tp1 hoist disc brake shoe monitoring and adjustment device

Abstract

The invention discloses a TP1 type hoist disc-shaped brake shoe monitoring and adjusting device, which includes a chassis and an end cover. hole, the chassis is screwed with the central threaded hole of the disc-shaped gate end cover through the thread on the outer circular surface, the outer end surface of the chassis is provided with a displacement sensor, and the inner end of the displacement sensor extends into the chassis In the central hole, the outer end surface of the chassis is connected to the end cover through connecting bolts, and a fixed cylinder is clamped between the end cover and the disc gate end cover, and the fixed cylinder covers the chassis and the displacement For the sensor, the fixed cylinder is provided with a wire outlet hole, and the signal wire of the displacement sensor passes through the wire outlet hole. The invention integrates the dual functions of fixing and adjusting the high-precision displacement sensor, and the high-precision displacement sensor detects the displacement of the connecting bolt of the disc brake piston, thereby effectively realizing the displacement monitoring of the disc brake shoe.

Description

[0001] Technical field: [0002] The invention relates to a disc brake shoe safety monitoring device for a hoist, in particular to a TP1 type disc brake shoe monitoring and adjusting device for a hoist. [0003] Background technique: [0004] The auxiliary shaft hoist of Chensilou Coal Mine was installed and put into operation in September 1993. The hoist is a JKMD-3.5×4 four-rope friction floor hoist produced by Luoyang Mining Machinery Factory. The hydraulic station is a TE163 constant produced by Luoyang Mining Machinery Factory. There are two torque braking hydraulic stations, and the braking unit is composed of 8 pairs of TP1-63 disc brakes and their brake shoe wear, brake disc deflection, and disc spring fatigue protection switches. The system has protection for disc brakes, including brake shoe wear, brake disc deflection, and disc brake disc spring fatigue. After nearly 22 years of operation, there are some problems as follows: (1) After long-term operation, the over D...

AI Technical Summary

Problems solved by technology

The system has protection for disc brakes, including brake shoe wear, brake disc deflection, and disc spring fatigue. After nearly 22 years of operation, there are some problems as follows: (1) After long-term operation, the over Due to the use of load fatigue, the components are aging, the performance is degraded, and the faults are frequent; (2) The original various protection devices are based on the traditional contact mechanical protection principle, which has been gradually eliminated in field use. The manufacturer’s spare parts have been discontinued, and the manufacturer’s supply cannot (3) The performance of the original protection devices is poor, the sensitivity is low, and it does not meet the needs of mine automation

(4) The fault diagnosis ability of the original system is poor, and it is difficult to judge the exact location and type of the hardware fault, which seriously affects the troubleshooting and prediction of the fault; (5) Due to the lack of spare parts and poor intelligent fault diagnosis ability, electromechanical accidents are caused after the fault occurs increase, the impact of the accident is prolonged, and the normal production of the coal mine is affected
