Elevator traction machine safety detection device and elevator control equipment

Abstract

The invention discloses an elevator traction machine safety detection device and a traction machine control device.A traction machine is installed on a rack, the detection device comprises a plurality of trigger units and a detection circuit, and the multiple trigger units are arranged on the different sides and/or the same side of the traction machine at certain intervals; each trigger unit comprises a switch beating plate installed on one of the traction machine and the rack and a detection switch installed on the other of the traction machine and the rack, and the switch beating plate and the detection switch are oppositely arranged at a preset interval in the tiltable direction of the traction machine. The traction machine inclines or swings to enable the switch beating plate to move relative to the detection switch so as to trigger the detection switch, and the detection circuit is connected with the detection switch and outputs a fault signal when the detection switch acts. Compared with the prior art, when the traction machine swings due to inclination or vibration, the switch beating plate can be driven to trigger the detection switch so as to generate a fault signal, and the running safety of an elevator is ensured.

Description

technical field [0001] The invention relates to the field of elevators, in particular to an elevator traction machine safety detection device and elevator control equipment. Background technique [0002] During the operation of the elevator, the elevator traction machine is tilted due to external reasons (such as elevator overload operation, resonance, failure of the shock absorber, earthquake, etc.), which may cause a certain displacement of the traction machine, and the traction sheave If the tilt occurs, the swing or jump of the elevator traction rope will increase, resulting in resonance in the car and poor passenger ride experience. If it is serious, the traction machine will seriously deviate from the installation position, the swing or jump of the elevator traction rope will be too large, and the elevator will be damaged. Interference between components occurs during operation, which eventually leads to safety accidents. At present, the general design scheme for the ...

Problems solved by technology

[0002] During the operation of the elevator, the elevator traction machine is tilted due to external reasons (such as elevator overload operation, resonance, failure of the shock absorber, earthquake, etc.), which will cause a certain displacement of the traction machine, and the traction sheave If the tilt occurs, the swing or jump of the elevator traction rope will increase, which will cause resonance in the car and cause poor experience for passengers on the elevator. If it is heavy, the traction machine will seriously deviate from the installation position, and the swing or jump of the elevator traction rope will be too large. Interference between components occurs during operation, which eventually leads to safety accidents

At present, the general design scheme for the traction device of passenger elevators is to add a shock absorber (such as shock-absorbing rubber) at the traction machine. There is no safety detection device for an elevator traction machine, which greatly affects the elevator. security of operation
