Problems solved by technology
[0003] Due to the heavy weight of the elevator car and the counterweight, there is a large friction force between the elevator traction steel wire and the elevator brake wheel. After frequent reciprocating use, it is easy to cause the elevator brake wheel to wear out or the elevator drags. Dangerous situations such as wear and tear of the lead wire may cause elevator safety accidents. Therefore, it is necessary to regularly check the wear degree of the elevator brake wheel and the elevator pull wire
[0004] At present, the relevant safety inspection work of the elevator is completed by inspectors on site, and the elevator needs to stop running during the safety inspection, and the elevator stoppage will inevitably bring inconvenience to people going up and down the stairs, and there are low inspection efficiency and detection The lack of low precision
In addition, the relevant safety inspections of elevators are carried out regularly, that is, they are intermittent inspections. If the brake wheels of the elevator are severely worn during the two safety inspections, safety accidents may occur

The invention provides an elevator brake wheel abrasion degree monitoring system which comprises a laser transmitter, a laser receiver, an infrared video camera, a sound signal collecting sensor, a height positioning sensor, a wireless data transmission equipment and a computer. The transverse position variation of an elevator traction steel wire between an elevator brake wheel and an elevator carand a balance weight is detected through the laser transmitter and the laser receiver. By means of the infrared video camera, a solid image of the elevator traction steel wire between the elevator brake wheel and the elevator car and the balance weight is obtained. By means of the computer, the appearance form of the solid image of the elevator traction steel wire is analyzed. By means of the sound signal collecting sensor, sound signals generated by rubbing between the elevator brake wheel and the elevator traction steel wire are collected, and the collected sound signals are analyzed by thecomputer. By means of the height positioning sensor, the actual space heights and positions of the elevator car and the balance weight are detected. By means of the computer, the actual space heightand position data of the elevator car are analyzed.
Description
technical field [0001] The invention belongs to the technical field of elevator safety monitoring, in particular to a monitoring system for the wear degree of an elevator brake wheel. Background technique [0002] The elevator brake wheel is the main component of the elevator brake, and it is also the structural part that is in direct contact between the elevator brake and the elevator dragging wire, and plays an important role in the working process of the elevator. The elevator pull wire is hung on the brake wheel of the elevator. One end of the elevator pull wire is connected to the elevator car, and the other end of the elevator pull wire is connected to the balance weight. When the elevator brake works, the elevator pull wire will follow the elevator brake. The rotation of the moving wheel drives the elevator car to move up and down. [0003] Due to the heavy weight of the elevator car and the counterweight, there is a large friction force between the elevator traction...
