An automatic detection device for a traction machine brake

Abstract

The invention discloses an automatic detection device of a traction machine brake. The automatic detection device comprises a detection module, a short message module and a plurality of indicator lights. The detection module and the short message module are connected with an elevator master controller, and bidirectional communication is performed. The input end of the detection module is connected with all sensors of the brake, the working state of the brake is monitored constantly, and the output end of the detection module is connected with all the indicator lights. According to the automatic detection device of the traction machine brake, CPU redundancy control of the elevator controller is fully utilized, automatic detection and fault early-warning functions of the traction machine brake are achieved, and cost is low. Compared with traditional detection, the automatic detection work is safer, operation is more convenient, troublesome procedures of manually overhauling the brake by inspectors are omitted, the controller can automatically detect the working states of all parts of the brake through the automatic detection device, the repairing and maintaining frequency and the quality of an elevator are easily ensured, elevator operation faults are greatly reduced, and elevator accidents are easily reduced.

Description

technical field [0001] The invention relates to an automatic detection device for a traction machine brake, which belongs to the technical field of automatic detection. Background technique [0002] As the country's urbanization continues to deepen and a large number of high-rise buildings have sprung up, the demand for elevators as the main means of transportation for high-rise buildings has risen rapidly in recent years. While the use of elevators has grown rapidly, the incidence of elevator accidents has also increased. In recent years, reports on elevator accidents have become commonplace. Behind the frequent occurrence of elevator accidents, there may be many reasons, including: installation, repair, maintenance, use, quality of accessories, etc. According to statistics, the elevator accident caused by elevator traction machine failure is one of the main reasons. The traction machine is an important part of every elevator and the main source of power to drive the elev...
