Title:
COOPERATIVE CONTROL METHOD FOR MULTI-CHANNEL BRAKING SYSTEM OF MINE HOIST
Document Type and Number:
WIPO Patent Application WO/2024/055769
Kind Code:
A1
Abstract:
A cooperative control method for a multi-channel braking system of a mine hoist. The abrasion loss of a brake shoe is obtained by means of detecting, in real time, position information of the brake shoe of each disk brake; an abrasion grade is divided by means of the abrasion degree of the brake shoe; three braking force distribution modes, namely, equal distribution, proportional distribution and exponential distribution, are formulated according to the abrasion grade, so as to dynamically adjust a set braking pressure of each disk brake; and each disk brake tracks and controls the set braking pressure by using a feedback pressure signal of an oil pressure sensor and using a pressure closed-loop control method. Therefore, the cooperative braking control which is based on the abrasion loss of a brake shoe and over a multi-channel braking system of a mine hoist is realized, and the problems of the service life of one or more disk brakes being shortened, the braking performance thereof being reduced, the braking thereof failing, etc., due to uneven abrasion of brake shoes are prevented, such that the usage safety and reliability of the braking system are improved.
