Electric ladder truck

The electric ladder truck device of the invention is applied to novel products in which people, goods are loaded up, down stairs, flat land, and can be easily rotated on the stairs relay layer.

Recently, various advanced industrial countries have encountered the problem of population aging, as well as many illnesses or disability caused by aging. The problem is that people who are old or disabled have to rely on wheelchairs or handicapped vehicles. Nowadays, many people live in apartments that generally have no elevators. They need to rely on stairs and between homes and flats. The large and small items or people in the house must go up and down on the stairs. Tao, but for a person with old age and disability at home, it is very painful. Usually, such an elderly family will buy a wheelchair for use at home, but the elderly live in the apartment for a long time. The limitation is that the body and the mind are prone to aging, the mood is not good, or the disease is caused. Therefore, it is necessary to go downstairs and walk outside. In addition to breathing fresh air, you can communicate with people, which can promote physical and mental health and forget the troubles. People often have to go in and out between the family and the hospital. We can imagine that it is quite difficult for the elderly living in the apartment to enter and exit the stairwell. One thing, you need to support many people at the same time to go down the stairs, which will be in trouble for those who are young and strong at home; and for those who live in apartments without elevators, if there is more bulky goods in the house, When going down the stairs and going out of the house, it needs to be carried by manpower. However, this kind of handling method is extremely wasteful of physical strength and poor work efficiency, and it consumes physical strength during the handling process, and it is easy to cause mistakes caused by fatigue when stepping on the ladder, resulting in a loss of ups and downs. Drops and other accidents, so that the way of manpower to move up and down the stairs to hide the upper and lower floors hides a huge accident crisis, another way is to install a simple lift on the outer wall to transport the goods to the home, which is installed on the outer wall Lifting and carrying operations can be carried out under the conditions of a simple lift and a space for hanging work. However, as urban development has fewer and fewer apartments with the above two conditions, the demand in the apartment has not stopped. It is obvious that for those who live in apartments that do not have elevators or who are engaged in handling work, it is clear that there is hope A safe, fast, and easy-to-operate handling tool that will help them easily transport people and cargo between the apartment and the flat will be a great benefit; in the case of the conventional ladder truck (200) (see The first figure shows an L-shaped body (100) having a relatively large angle. The body (100) is provided with a motor (101) at a position near the front end, and a front wheel (102) is disposed at the rear end of the body (100). The rear wheel (103) and the driven wheel (104) are provided with pulleys (105) on both sides to pass between the three wheels (102, 103, 104), and on the upper side of the body (100), a detachable group positioning armrest bracket is provided ( 106), the bracket is at a predetermined position on one side and is provided with a bearing portion (107) for carrying the human body. When the motor is started, it can travel in the stairwell, and the utility model mainly uses the outer edge of the pulley (105) to contact the card. The force is driven by the stepped edge. When walking between the stairwells, the flat portion (108) and the rear inclined portion (109) of the pulley (105) are used to crawl up and down the stairwell, and the flat ground is flat. Department (108) travels; however, the actual experience of this conventional ladder truck (200) found that the following problems still exist, the conventional crawl Although the ladder structure can work on the upper and lower steps to carry the human body or heavy objects, the rotary relay floor of the general house is about 3M/1.3M/1.2M because of its height × length × width, so the length × The wide floor area has a narrow space for rotation, and thus the total length of the integrally fixed ladder body (100) and the bearing portion (107) and the bracket (106) is too long, and often encounters when the stairs are to be relayed on the stairs. The wall surface may not be swung, which causes inconvenience in use. In addition, the flat portion (108) and the rear inclined portion (109) of the pulley (105) are integrally formed in a fixed form, and the angle cannot be bent to adjust the angle to the stairs of various inclinations. The layer is used because the slope design of each staircase cannot be applied in one piece. In addition, the conventional ladder truck carrier (107) is a fixed form that is not comfortable when it is used. The above various reasons cause the ladder car market to not respond. Jia can't promote it in a large amount. In view of the problems existing in the above-mentioned structure of the ladder truck, how to develop a new technology that is comfortable to ride and can be rotated in the stairwell is a eagerly awaited by consumers, and it is also a goal of the relevant industry to strive to develop breakthroughs.
