Embodiment Construction
[0028] A method for detecting three times the rotational torque of the braking device of a mine hoist. The hoisting motor is driven by the transmission device of the electric control system, and the output torque of the motor of the hoist is detected by the transmission device software. It is collected and automatically calculated by the testing software and converted into the rotational torque of the hoist. , the moment value Rotational torque value with hoist 1 / 2 brake Comparison (one test for each mode of brake adjustment I and brake adjustment II), a method to automatically judge whether the braking torque generated by the braking device is less than three times the rotational torque, and display the detection results in Chinese form "torque test meets requirements" or "torque Test does not meet requirements" is displayed in the superordinate monitoring system.
[0029] The specific operation method is: add a detection switch, a torque test button and a test program to...

The invention belongs to the technical field of braking device moment detection methods, and provides a detection method for the triple rotation moment of a shaft hoist braking device in order to solve the technical problem that in an existing moment detection method for the hoist braking device, moment testing of the hoist braking device can not be conveniently conducted at any time. The detection method comprises the steps that an electric control system driving device is adopted to drive a hoist motor, the output torque of the hoist motor is detected, the output torque of the hoist motor is automatically collected by adopting testing software and automatically calculated to be converted into the hoist rotation torque, a hoist rotation torque value is automatically compared with a hoist brake rotation moment value, whether the braking moment generated by the braking device is smaller than the triple rotation moment or not is automatically judged, and a detection result is displayed on an upper monitoring system. By adopting the detection method, moment testing of the braking device can be conveniently conducted at any time, and compared with an existing detection method, the efficiency is high, and the moment detection time is greatly shortened.
Description
technical field [0001] The invention belongs to the technical field of torque detection methods for braking devices, and in particular relates to a detection method for three times the rotational torque of a braking device of a mine hoist. Background technique [0002] Hoists are widely used in vertical shafts and inclined shafts of mines. They are mainly responsible for lifting minerals, lifting personnel, materials and equipment, etc., and are the throat of mine system equipment. The work is carried out safely and smoothly. Article 426 of the 2016 edition of the "Coal Mine Safety Regulations" stipulates that the performance of the mechanical brake device of the hoist must meet the following requirements: [0003] The braking torque multiple must meet the following requirements: [0004] 1. The ratio K value of the braking torque generated by the braking device to the actual lifting maximum load rotation torque shall not be less than 3. [0005] 2. For hoists with a small...
