Security protection air-cushion for lifter

Abstract

The invention relates to a safety protection air cushion of a lift, with reasonable structural design and fast motion, which solves problems existing when the existing lift is out of control and a safety device against falling is in failure and comprises a damping device assembled at the bottom of the car of the lift and a monitoring control circuit of a single chip thereof; technical points thereof comprises the following steps: the damping device adopts an air cushion with a gas generator and is fixed at the center-of-gravity position of the bottom of the car in a hiding mode; a speed sensor and a transmitting and receiving machine of a position sensor in the monitoring control circuit of the single chip are assembled at the top and the bottom of the car respectively and connected with a single chip circuit in series; the transmitting and receiving machine is connected with a relay in a gas generator circuit in series and a reflector of the position sensor is assembled at the setting position of a car rail at the opposite side of the transmitting and receiving machine; the air cushion can form landing buffering automatically at the instance of landing of the car when the lift is out of control, thus playing the role of protecting personal safety and reducing property loss.

Description

technical field [0001] The invention relates to an auxiliary safety protection device for vertical lifting equipment, in particular to an elevator that can automatically form buffer control when the elevator is out of control and the anti-fall safety device fails, and the fall is inevitable at the moment before the car falls to the ground. Air cushion for safety protection. It is mainly suitable for vertical lifting equipment such as elevators, construction hoists and mine vertical conveyors. Background technique [0002] At present, vertical lifting equipment such as elevators, construction hoists and mine vertical conveyors all have their own anti-falling safety devices, and their safety performance is better. However, these anti-fall safety devices are affected by factors such as manufacturing and installation, coupled with the occurrence of component wear and fatigue operation, operational errors and illegal operations during operation, which exacerbates the hidden dang...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide an elevator safety protection air cushion with reasonable structural design and quick action, which fundamentally solves the problem of a fall accident when the existing anti-fall safety device fails, and can prevent the elevator from being out of control and the anti-fall safety device. When the unavoidable situation of failure and fall occurs, the moment before the car lands, a landing buffer is automatically formed to protect personal safety and reduce property losses
