Problems solved by technology

[0012] Although protected by four lines of defense, 19 people died in the fall of an elevator in Wuhan; a major accident involving the death of 5 people in a high-rise construction elevator fall in Changzhou, Jiangsu, caused frequent minor faults in the elevator, which caused a bad experience for users. Without more comprehensive protection, the life safety of users cannot be guaranteed. No matter how good the quality is, accidents cannot be avoided. Elevator protection is still limited. While it is convenient to travel, there are also dangers that threaten life safety. , the existing elevator needs a safer and more stable protective device

Abstract

The invention discloses an out-of-control falling buffer control device for an elevator car, and belongs to the field of elevators. The out-of-control falling buffer control device for the elevator car comprises a control cabinet, a guide rail, a buffer base, a traction machine and an elevator shaft, wherein the control cabinet and the traction machine are mounted at the upper end of the elevatorshaft; the guide rail is mounted in the elevator shaft; the buffer base is positioned on the bottom of the elevator shaft; a car is connected on the guide rail; a control panel is mounted in the car;the lower end of the car is equipped with a buffer mechanism; the buffer mechanism comprises a friction pad and an air inflation bag; one end of the friction pad is fixedly connected with a heat conducting plate; and one end, away from the friction pad, of the heat conducting plate is fixedly connected with a thermal expansion layer. In case of realizing that four defense lines of an elevator loseefficacy, a fifth defense line can be provided to achieve the buffer control effect while the car is out of control to fall, so that a last defense line of life is provided for personnel in the elevator, and therefore, personnel casualties are reduced.

Description

technical field [0001] The invention relates to the field of elevators, in particular to a buffer control device for an elevator car falling out of control. Background technique [0002] When the elevator falls, the person and the elevator accelerate down together, and the speed of both becomes the same. Falling to the ground, because the elevator hit the bottom, the speed changed from extremely large to zero in a very short period of time, and people were injured or even died due to the great impact. [0003] Now there are four lines of defense in the elevator: [0004] The first line of defense: steel wire rope [0005] Generally speaking, there are at least 5 elevator wire ropes. With the strength of the wire rope, it is not a problem to break 1-2 wire ropes. However, in a static state, a wire rope can pull a car. At the same time, the probability of the wire rope breaking completely is basically 0. [0006] The second layer of defense: car safety gear [0007] Eve...
