One. introduction

China electric stair climbing dolly is a new type of stair climbing equipment. Electric load stair climbing machines are widely used in transportation, distribution, and other related industries. It can reduce the burden of heavy object handling at work and improve work efficiency. Without the help of others, a stair-climbing trolley, which can quickly complete the work of heavy objects upstairs, is efficient transportation and distribution equipment.

How can we find the proper stair climber? What kind of electric stair climbing car is good? Share some relevant information for your reference.

Two. Design principle of electric dolly stair climber

China electric stair climbing dolly is divided into two parts: the control part and the body part.

• The primary function of the control part is to control the motor movement of each part of the car body, including the forward and reverse rotation of the front and rear gears and the forward and reverse process of the front and rear wheels.

• The critical part of the car body is the climbing mechanism. The climbing mechanism adopts two sets of rack and pinion mechanisms, each located at the front and rear.

The principle of electric stair climbing dolly is that the front gear rotates forward to lift the front load and the front wheel when the first step is started. When the front wheel rises to a height of a degree, the rear wheel turns, and the front wheel is placed on the next step. The rear wheel stops rotating, the front gear reverses, and the rear gear rotates forward so that the middle of the car body can be lifted; at this time, the front and rear wheels move forward at the same time so that the seat of the car also falls to the upper step, and then reverse the rear gear and lift the rear wheel Level with the front wheel and move on. In this way, the car went up a step smoothly. In this way, the cycle has been continued, and the trolley can smoothly climb the stairs.

Compared with other cars that can go upstairs, China electric stair climbing dolly has the following advantages:

(1) The design principle is intuitive.

(2) The trolley has a simple structure and is easy to manufacture.

(3) Stairs with variable height can be climbed.

(4) The whole climbing process can keep the body moving safely and smoothly.

(5) According to the principle of ascending, descending steps can also be performed.

Three. electric stair climbing dolly structure

1. Materials

The most widely used materials for electric dolly stair climbers on the market are carbon steel and aluminum alloy. The carbon steel material is economical and can achieve high-strength rigidity, making the machine more durable; the aluminum alloy material is lighter and easier to carry. Its material strength is equally strong and durable.

2. Battery

China electric stair climbing dolly battery recommends the use of lithium batteries. Lithium batteries have a high cost, strong energy density, and are relatively lightweight, which can better control the weight of the entire machine (lead-acid batteries are about 4-5 times heavier than lithium batteries); it can significantly reduce the labor generated by carrying.

3. Protection level

We will inevitably encounter bad weather and environment in our daily distribution process. The electric dolly stair climber must provide a safe operation design and corresponding protection measures such as waterproof and dustproof. It can effectively avoid water splashing and dusty situations in life and prevent the machine from malfunctioning during operation.

4. Tires

Solid tires are wear-resistant and puncture-resistant, and are more suitable for use in harsh environments; pneumatic tires have better shock resistance. In the process of handling heavy objects such as household appliances and fragile goods, pneumatic tires can better buffer and reduce damage to goods.

Four. China electric stair climbing dollyEase of operation

The key to using a stair climbing machine is the operation skills. A good stair climbing machine should be easy to learn and master the operation quickly.

1. Security

In addition to skilled operation skills, the machine operation switch adopts a touch-type (click to move) design, press to move, release to stop; the touch-type design can effectively avoid accidents during distribution and handling.

2. Stair climbing speed

It is a mistake to blindly pursue speed without considering the safety of operators and items. The rate of the electric dolly stair climber needs to be reasonably assumed. The speed should be well designed to ensure the weight limit of the operator and the safe handling of the equipment. It is recommended to have two speeds, one fast and one slow. The slow gear setting is usually used for beginners to practice. After you are proficient, you can choose the quick file to improve work efficiency.

3. Noise

When working indoors, it is necessary to consider whether the noise generated during the operation of the stair climber affects people's everyday life. When the electric dolly stair climber operates, most noise comes from the motor. To better control the noise, the selection of the motor is also a knowledge. The brushless DC motor is recommended. To ensure the maximum load of 200 kg, the noise can be kept at a reasonable level and controlled below 70 decibels.

4. The core technology of the product

The core technology is like the human brain for electric machines like the electric dolly stair climber. The control system of the heavy object climbing operation must be stable, have a low failure rate, and durable. Therefore, it is essential to choose an experienced R&D team who can provide strong support for our core technology. This will give you more peace of mind when using the device.

5. Fast after-sales service

The quality and function of the product itself must be considered when purchasing a suitable electric dolly stair climber, but after-sales service is also essential. Choosing a company with strength and brand protection can solve your worries.

Five. How to maintain China's electric stair climbing dolly?

1. If the electric stair climbing dolly works in a high temperature and high humidity environment like this summer, it is prone to performance degradation, so the workers should usually place the stair climbing dolly indoors to ensure that its metal The structure is more stable, can exert its performance, and can prolong the life of the battery at the same time!

2. Do not put the stair climber in the car's trunk. After using the electric dolly stair climber, many customers directly prevent the stair climber from the box and then park it in the sun exposure environment because of the electric dolly stair climber. The power supply is the battery. For any storm, we must be careful not to prevent it from being in a high temperature and airtight environment, which is a dangerous thing.

3. It is necessary to regularly check the parts of the electric dolly stair climber to effectively avoid the damage of the plastic parts from breaking or deforming due to the high temperature and ensure the safety of the stair climber. Before using the stair climbing machine, carefully check the screws and other parts of the stair climbing machine to ensure that there is no problem before starting to use it.

4. Pay attention to charging in time. In summer, it is necessary to change frequently to ensure that the battery is always in a "full" state to ensure the battery life and the electric dolly stair climber operate normally. At the same time, choose to charge it in a dry, ventilated, and no direct sunlight environment, but do not charge overnight, and the charging time should not be too long. It is recommended to set it at least once a month. Otherwise, it will seriously affect the battery life!

We recommend the stair climbing machine developed by China DRAGON based on the above points.

How to choose an electric wheelchair? The first thing we need to consider is that electric wheelchairs are for users, and each user's situation is different. From the perspective of the user, based on basic data such as height and weight, daily needs, use environment and special surrounding factors, etc., a comprehensive and detailed assessment should be carried out from the perspective of the user, so that effective selection can be carried out, gradually subtracted until a suitable electric wheelchair is selected.

How to choose an electric wheelchair? In fact, the conditions for selecting electric wheelchairs and ordinary wheelchairs are basically similar. When selecting the seat back height and seat width, the user can sit on the electric wheelchair, the knees are not curved, and the calf can be naturally lowered at a 90° right angle. The appropriate width of the seat is, at the widest position of the hips, add 1-2cm to the left and right.

If the user sits, the knees are slightly high, and the legs will be curled, and it is very uncomfortable to sit for a long time. If the seat surface is narrow, the sitting will be crowded and wide, and long-term sedentary will cause secondary injuries such as spinal deformation.

Then consider the weight of the user. If the weight is low, the use environment is flat, and the brushless motor is cost-effective; if the weight is heavy, the road condition is not very good and needs to drive long distances, it is recommended to choose a worm gear motor (brushed motor).

The easiest way to detect the power of a motor is a climbing test, whether the climbing test motor is easy or slightly strenuous. Try not to choose the motor of the horse-drawn cart. There will be many faults in the later stages. If the user has more mountain roads, it is recommended to use a worm motor.

The battery life of an electric wheelchair is also a concern for many users. To understand the properties of the battery and the AH capacity, if the product description is about 25 kilometers, it is recommended that the budget life be 20 kilometers, because the test environment and the actual use environment will differ. For example, the battery life in the north will be reduced in winter, and try not to drive an electric wheelchair out during colder times, which will cause great and irreversible damage to the battery.

Generally speaking, the battery in AH capacity and range is approximately:

• 6AH battery life 8-10 km

• 12AH battery life 15-20 km

• 20AH battery life 30-35 km

• 40AH battery life 60-70 km

Battery life is related to battery quality, weight of electric wheelchairs, passenger weight, and road conditions.

How to choose an electric wheelchair? It is also important to note the overall width of the electric wheelchair. Some families have narrow doors and need to measure the width and choose an electric wheelchair that can be freely accessed. Most electric wheelchairs have a width of 55-63cm, and some have made it more than 63cm.

When buying products, you need to carefully understand the instructions, check whether the product label brand is consistent with the manufacturer. If the product label brand is not consistent with the manufacturer, it is an OEM product.

Finally, let's talk about the warranty time. Most of them are one-year warranty for the whole vehicle, and there are also separate warranties. The controller is regular for one year, the motor is for one year, and the battery is 6-12 months.

There are also merchants who have long warranties, and ultimately follow the warranty instructions in the manual. It's worth noting that some brands have warranties based on the factory date, and some are based on the sell-by date.

When buying, try to choose a production date that is closer to the date of purchase, because most electric wheelchairs have batteries that are installed directly on the electric wheelchair and are sealed and stored and cannot be maintained separately. If left for a long time, the battery life will be affected.

Instructions for charging and using batteries

Friends who have been using electric wheelchairs for a long time may find that the battery life is slowly short, and an inspection finds that the battery drum is packed. Either you run full and run out of power, or you can't charge it how you charge it. Don't be in a hurry, tell you how to properly maintain your battery today.

1. Never charge an electric wheelchair immediately after using it for a long time

In the driving state of the electric wheelchair, the battery itself will heat up, plus the weather is hot, the temperature of the battery is even as high as 70 ℃. In the case of the battery not cooled to the ambient temperature, the electric wheelchair will be charged immediately as soon as it stops, which will exacerbate the battery's lack of water, reduce the service life of the battery, and increase the risk of battery charging.

It is recommended to park the electric vehicle for more than half an hour and charge it after the battery is fully cooled. If the battery or motor is abnormally heated during the driving of the electric wheelchair, please go to the professional electric wheelchair maintenance department for inspection and repair in time.

2. Don't charge an electric wheelchair under the sun

The battery also heats up during charging, and if charged under direct sunlight, it can also cause the battery to lose water and cause a drum bag to the battery. Try to charge the battery in a cool place or choose to charge an electric wheelchair in the evening.

3. Don't mess with chargers to charge electric wheelchairs

Charging an electric wheelchair with a mismatched charger may result in damage to the charger or damage to the battery. For example, using a charger with a large output current to charge a small battery can easily cause the battery to charge the drum pack.

It is recommended to go to a professional electric wheelchair after-sales repair shop to replace the matching high-quality brand charger to ensure the charging quality and prolong the service life of the battery.

4. Not charging for a long time or even charging all night

Many electric wheelchair users often charge all night for convenience. The charging time often exceeds 12 hours, and sometimes forgets to cut off the power to charge for more than 20 hours, which will inevitably cause great damage to the battery. Charging multiple times for a long time can easily cause the battery to charge the drum due to overcharging. Generally, electric wheelchairs can be charged for 8 hours with a matching charger.

5. Infrequent use of fast charging stations to charge batteries

Try to keep the electric wheelchair battery fully charged before traveling, and depending on the actual range of the electric wheelchair, you can choose to take public transportation for long-distance travel.

After reading this article, do you have a general understanding of how to choose an electric wheelchair?

People eat grains and cereals, it is inevitable that there are times when they get sick, and nowadays, with advanced medical care, when you get sick, of course, you will go to the hospital for treatment. Most people are treated through intravenous infusions to reduce inflammation and cough, etc. Therefore, when there is a high incidence of some diseases, we will see a large number of people sitting in the infusion room are dripping or waiting for the drip. There are even some elderly people who do not have enough nutrients in the heat of the day and go for nutrient delivery by IV. So for hospitals, IV stand are an indispensable tool. So what are the different varieties of IV stand, what materials are they made of, and are the prices of IV stand on the market now high? Let's talk about it briefly today!

1. the price of IV stand depends on different varieties

1.1 children's IV stand price is higher

Children's illness often makes all parents very heartbroken. Especially when the fever does not go down, parents will take their children to the IV drip, but look at the child is very mobile, so in the past, only the parents can only hold the child's hand throughout the IV drip, and the previous IV stand are for adults, did not take the child's small into account, and now the IV stand have special can provide for children to use, such as in the children's hospital infusion room inside the There are a large number of stand that are specifically provided for children's IV infusion, and the price of these children's IV stand is slightly higher. Not only can they be adjusted up and down according to the size of the child, they can also be adjusted according to the length of the arm, and they can also have the function of fixing the child's arm, which greatly liberates the parents and the child.

1.2 the price of removable IV stand is relatively high

Most of the intravenous infusion is fixed directly on the seat, generally speaking, the left and right front and rear can be provided to four people for infusion use. But now there are also many are movable IV stand, these IV stand can be used one to one. The main function is that when some patients need to go to the bathroom, or when inpatients need to take a drip to the examination, they can move directly to their desired destination. Then the price of this kind of IV stand will be higher, in addition to the original structure, it also needs to have a wheel function underneath.

2. The price of IV stand depends on different materials and patents

2.1 The price of IV stand is slightly higher for high quality material

In fact, many of the IV stand used to be quite simple, and were made of wooden sticks, similar to coat hangers, to place the infusion. But because the loss of wood is relatively large, and the hospital because itself is the need for high-intensity sterilization, so the wooden loss will be particularly fast, now most of the use of stainless steel infusion rod, so that can be carried out for many years without changing, and can be for the role of corrosion to reduce the impact to a minimum. Therefore, the price of stainless steel IV stand is slightly higher.

2.2 Various patented IV stand are slightly more expensive

Even simple IV stand need to take into account the actual use of the patient's problems, and also the handling, installation and other problems. Previously, the IV stand were all integral, so handling often required a special height of the carrier to handle. But now many IV stand manufacturers have made more disassembly features, not only that, but also more perfect support devices for smooth infusion paths according to the length and height of the patient's infusion, so that the patient can avoid backflow of blood due to low height or poor infusion, so the price of these patented IV stand is slightly higher.

3. IV stand price increase reflects humanization

3.1 IV stand price control

In fact, nowadays, many hospitals, even some private hospitals, are quite attached to IV stand, and the price also varies greatly, some cheaper ones may be a hundred dollars, but some multi-functional ones need to be priced at several thousand dollars. Then you can buy in bulk by more than one to reduce the price of IV stand to some extent.

3.2 What does the higher price of IV stand reflect?

When the price of an item is getting higher, it directly means that the demand for that product is getting higher, and IV stand are one of them. The patient is already in pain, is it possible that the patient enjoys limited comfort in the process of treatment is also what many people are seeking now. From the previous single sitting straight to infusion, to now being able to lie down and be able to infuse according to their most comfortable angle and height is already an improvement. This is why the price of IV stand is getting higher and higher, especially for the many details that are now being improved to enhance the experience, with patented IV stand being a very good example.

Patients in the hospital are more concerned about their condition, the best treatment they can do, the best treatment effect, not the price of IV stand, but for the hospital or clinic, if you can use the best and most modern, the most humane IV stand, can provide more convenient services to patients of the equipment, so that is the real patient-oriented!

Examination bed is a kind of medical bed, also called diagnosis bed. The examination bed mainly assists doctors in examining patients to achieve the following expected purposes: 1. Prevention, diagnosis, treatment, monitoring, and relief of diseases; 2. Diagnosis and treatment of injury or disability , guardianship, mitigation, compensation.

Exam beds are mainly used in clinics and hospitals, and are basically used in different departments. Commonly used in gynecological examination beds, it is also often used in pediatric examinations, CT examinations, obstetrics and gynecology examinations, electrocardiogram examination beds, color ultrasound examinations, endoscopy examinations, dental examinations, ophthalmological examinations, gastroenteroscopy examinations, magnetic resonance examinations, ultrasound examinations Examinations, urological examinations, portable imaging examinations, anorectal examinations, neurological examinations, TCM internal medicine examinations and many other departments.

For example, the movable multifunctional gynecological examination bed can be used for patients with illness, postoperative patients, critically ill patients, and fracture patients. For deformed and fractured patients who cannot get out of bed, the movable multifunctional gynecological examination bed can reduce the number of getting out of bed and prevent the risk of falling on the gynecological examination bed again.

Gynecology is a department that occupies a large proportion in the hospital, so it is equipped with more inspection equipment. Among them, the gynecological examination bed is one of them. Our examination bed is mainly made of stainless steel, which is reasonably set according to the human body structure. The gynecological examination bed is also known as the gynecological operating table. It is an auxiliary medical equipment to provide various hospitals, clinics, family planning stations, mobile gynecological examination vehicles for various gynecological examinations, diagnostic operations and family planning examinations. This series of products can arbitrarily adjust various body positions of patients when they visit a doctor according to the actual situation. The curve design of the product focuses on humanization and comfort, and the seamless design of the bed surface is more conducive to the cleaning of equipment and the cleaning and protection of medical staff. The power system of this series of products is driven by three power systems: full hydraulic, motor and mechanical operation.

 For example, CT examination bed, which belongs to high-end imaging examination, can clearly reflect the internal anatomical structure of human tissue, and can also clearly reflect the nature of the lesion, which provides great help for clinical treatment. CT can examine many organs and tissues of the human body, such as the skull, facial features, lungs, mediastinum, heart, liver, gallbladder, pancreas, spleen and kidney, stomach, biliary system, bowel, bladder, uterine appendages, prostate, vertebral body, limb bones, blood vessels, etc. Among them, the diagnosis of lesions by chest CT and the screening of small pulmonary nodules by artificial intelligence are the most widely used in all imaging examinations, and the advantages are also obvious.

Through magnetic resonance, we can also perform good localization and characterization of tumor tissue, as well as follow-up after treatment. For example, the more common brain tumors are in the brain or outside the brain. What functional areas are affected by its scope and region, and how to do it, magnetic resonance can also give good guidance. For example, breast cancer, we all know mammography, but most of us Chinese have dense breasts, the contrast on mammography is not very good, and sometimes the lesions are missed. Magnetic resonance imaging has a good contrast. After dynamic enhancement, it can reflect the blood supply characteristics of the lesions, and can also distinguish benign from malignant. For example, for parenchymal organs such as liver and pancreas, MRI also plays an important role. Especially in the detection of early liver cancer, in the process of the development and change of benign regenerative nodules, such as malignant liver tumors,

We can detect very small lesions very early through magnetic resonance imaging, so as to make early diagnosis and early treatment, so that the patient's prognosis is very good. For example, benign prostatic hyperplasia and even prostate cancer, which are more common in older men, can be well positioned and diagnosed on MRI. Women's uterus, uterine body cancer, cervical cancer, its staging, the accurate preoperative staging is also based on our magnetic resonance above - some characteristic signs. In addition, the application of MRI in bone and joints is also very extensive. For example, whether the bones, cortical bone, and marrow are affected, and whether the components of ligaments and soft tissues have lesions, can be well identified on MRI.

Doctors ask patients a lot of questions when making orders. For example, has the pacemaker been spared, because Dr. Chang will ask patients a lot of questions when prescribing orders. For example, have you spared the pacemaker, because often Regular pacemakers cannot enter the magnetic field. With the advancement of technology, there are also magnetic resonance compatible pacing.

However, the MRI examination should be carried out under the guidance and accompaniment of a cardiologist. The doctor will also ask if

Let go of the brackets. Currently, all brackets can enter the magnetic field, but it is limited in time. Usually within 3 weeks. To be safe, the doctor will advise the patient to re-enter after 3 months, if necessary. Check the magnetic field. Have you ever replaced artificial joints? This is also a question often asked by doctors. because of the metal joints

It cannot enter the magnetic field. But currently, most artificial joints are alloy components that can be safely entered magnetic field. Of course, there are other implants, such as electronic ear sockets, prosthetic eyes, etc., when the doctor asks

When waiting, you must answer truthfully, - everything is considered from the perspective of patient safety.

In addition, we should also pay attention to some external metals, such as keys, coins, watches, banks

Cards, mobile phones, etc., cannot enter the magnetic field. - Typically, they degauss the device or cause it to malfunction. In severe cases, these metal-containing substances will hurt the human body after entering the magnetic field, especially if they are large. A little metal object will also hurt the machine and cause the machine to malfunction, so these are also what we are entering

Special attention should be paid to magnetic fields.
