Safe anti-falling buffer device for building hoistway and implementation method of safe anti-falling buffer device

Abstract

The invention discloses a safe anti-falling buffering device for an building hoistway and an implementation method of the safe anti-falling buffer device, belongs to the technical field of hoistway inner buffering, solves the problem that a lift car tilts laterally and rotates in the process of falling along a hoistway to impact the side wall. The device comprises a lift car base, a rope sling buffering mechanism, a spiral sliding way and an anti-falling ferrule mechanism. The spiral sliding way is formed in the inner wall of the lift car base, the rope sling buffering mechanism is connected into the spiral sliding way in a sliding mode, and the anti-falling ferrule mechanism fixed to the inner wall is arranged at an end opening of the lower end of the spiral sliding way. When a falling object and the lift car base fall downwards, the falling object and the lift car base make contact with the rope sling buffering mechanism firstly, the rotating impact force of the rope sling buffering mechanism pushes a first sliding block assembly and a second sliding block assembly to slide downwards along the spiral sliding way, the rotating impact force is eliminated, the overall falling inertia of the falling object is buffered, the distance difference between the two sides of the falling object is reduced, and the falling angle of the falling object is corrected.

Description

technical field [0001] The invention relates to the technical field of buffering in a well, in particular to a safety anti-falling buffer device for a building well and an implementation method thereof. Background technique [0002] The elevator shaft is the space where the car and the counterweight or the plunger of the hydraulic cylinder move. This space is bounded by the bottom of the hoistway pit, the hoistway wall and the hoistway roof. The size of the hoistway determines the inner net size of the car according to the rated load quality and rated speed of the elevator, and further calculates the outline size of the car and the hoistway. size. The size of the hoistway refers to the internal width and depth determined by the outer dimensions of the car, the size of the counterweight, the clearance between the car and the counterweight, and the clearance between each of them and the hoistway wall. During the operation of the building hoistway, there may be derailment and ...

AI Technical Summary

Problems solved by technology

[0005] However, the above-mentioned patent does not solve the problem that the car touches the wall of the hoistway during the process of falling along the hoistway, thereby causing a secondary impact. The car is considered to fall as a whole, and when the car hits, some parts fall off and cause the same hazard. It did not consider, nor did it take into account the non-vertical falling of the car. It only considered and solved the overall vertical falling problem of the car during the process of falling along the hoistway, resulting in a large defect in the safety of the hoistway.
