Elevator car with emergency fall prevention function

Abstract

The invention relates to an elevator car with an emergency anti-falling function. The elevator car comprises a car body, wherein a top plate is mounted on the upper end face of the car body; a top auxiliary device is mounted on the top plate; side wall buffering devices are symmetrically mounted on the outer walls of the left end and the right end of the car body; and a bottom anti-falling deviceis mounted at the lower end of the car body. The elevator car can solve the following problems existing in the using process of an existing elevator with a car structure that a, when the car falls inan elevator shaft, huge impact force generated by free falling cannot ensure the stability of emergency braking of the car only by depending on a steel wire rope for pulling the car, the safety performance is poor, and the life safety of a user in the car is seriously endangered; and b, when the elevator falls, a gap between the elevator and the elevator shaft cannot buffer the falling elevator, the impact force in the falling process of the elevator cannot be reduced, the position of the elevator after stopping cannot be ensured, and rescue of the user in the car under the fault condition ofthe elevator is not facilitated.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator car with an emergency fall prevention function. Background technique [0002] A vertical lift has one car. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary to use elevators as a general term for vertical transportation in buildings regardless of their driving methods. With the development and progress of society, high-rise buildings have become the mainstream buildings in the current society. Elevators are indispensable supporting facilities in high-rise buildings. Elevators The safety and stability of elevators are related to the safety of users. Although the production technology of elevators has been significantly improved, safety accidents caused by elevator falls are not uncommon. [0003] The following problems exist in the use of existing car structure elevators, a. When the car f...

Problems solved by technology

It is customary to use elevators as a general term for vertical transportation in buildings regardless of their driving methods. With the development and progress of society, high-rise buildings have become the mainstream buildings in the current society. Elevators are indispensable supporting facilities in high-rise buildings. Elevators The safety and stability of elevators are related to the safety of users. Although the production technology of elevators has been significantly improved, safety accidents caused by elevator falls are not uncommon.

[0003] The following problems exist in the use of existing car structure elevators, a. When the car falls in the elevator shaft, the huge impact force generated by the free fall can not be ensured by the car’s emergency braking stability simply by relying on the steel wire rope that pulls the car , the safety performance is poor, which seriously endangers the life safety of the users in the car. b. When the elevator falls, the gap between the elevator and the elevator shaft cannot buffer the falling elevator, and cannot reduce the impact of the elevator falling. Force, unable to guarantee the position of the elevator after it stops, which is not conducive to the rescue of people in the car when the elevator fails

[0004] For the technical problems existing in the use of elevators at present, personnel in related technical fields have made adaptive improvements after research, such as the Chinese utility model patent No. 2014202019968, a car elevator, which can not only easily trigger the elevator The brake switch effectively prevents the car from being overloaded and has a high safety index. However, the above-mentioned problems in the use of the car structure elevator are not mentioned.
