Problems solved by technology

[0003] 1. In the daily elevator car, when the elevator traction rope breaks or the drive motor fails, due to the small friction between the car and the wall, the car is prone to slide down rapidly, causing psychological panic or even the circumstances of the injury;
[0004] 2. When the car rapidly slides down to the bottom, due to the reaction of the force, it is easy to have a large impact on the car itself and the passengers in the car, which will affect the service life of the car and the personal safety of passengers

Abstract

The invention relates to an anti-fall elevator car, which includes a car body, an anti-fall device, a base and a return frame. The upper and lower ends of the car body are symmetrically equipped with anti-fall devices, and the anti-fall devices are symmetrically arranged front and rear. The lower part of the body is provided with a base, and the left and right ends of the base are installed with a return frame. The car body is located in the middle of the return frame. Falling setting, the anti-falling device set by this device can change the friction between the elevator car and the wall when the elevator car fails and falls rapidly, so as to improve the friction between the elevator car and the wall and reduce the friction between the elevator car and the wall. The falling speed of the car can be controlled to achieve a good anti-drop effect of the car.

Description

technical field [0001] The invention relates to the field of elevator cars, in particular to an anti-fall elevator car. Background technique [0002] The car is a box-shaped space used by the elevator to carry and transport people and materials. The car is generally composed of car bottom, car wall, car roof, car door and other main components. Its internal net height should be at least 2m. The car frame is the load-bearing structure of the car. Passed to the traction wire rope, the car frame is generally composed of upper beams, columns, bottom beams and pull bars (to adjust the level of the car bottom and prevent the floor from tilting), etc. The car body is a closed wall that forms the car space. There must be no other openings outside the necessary entrances and exits and ventilation holes. The car body is made of materials that are non-flammable and do not produce harmful gases and smoke. For the safety and comfort of the passengers, the clear height of the car entranc...
