Disc type brake performance detection method and the device

Abstract

The invention relates to a brake property check method of disc damper brake, and a relative device, wherein the back end of a disc spring of the disc damper brake is arranged with a sensor which signal is output via a lead wire. When the damper brake works, the pressure on the disc spring via the sensor can directly be used to measure the positive pressure on the disc damper brake. A support of the disc damper brake along the axle of the damper brake is arranged with a touch Hall displacement sensor which measuring rod is contacted with the side end of a block base to effectively measure the displacement of brake space. The invention uses a data pickup and process system to measure the idle time and brake decelerate value of the damper brake. The inventive method can confirm the reliability of damper brake in use, with high measurement accuracy, strong interference resistance, small volume, and long service life, more particularly to be used for checking the brake property of disc damper brake. The inventive method has simple and easy operation, high check accuracy, simple structure, easy installment, easy maintenance, and wide application.

Description

technical field [0001] The invention relates to a method and a device for detecting the braking performance of a disc brake, and is especially suitable for detecting the braking performance of a front-mounted or rear-mounted disc brake of a mine hoist. Background technique [0002] At present, the disc brakes installed on the hoist include the old disc spring rear type and the new disc spring front type. The main reason for accidents such as high-speed overwinding and enlarged slippage of mine hoisting equipment is the insufficient braking torque of the brake, and the insufficient positive pressure is the main reason for the insufficient braking torque of the brake. The "Coal Mine Safety Regulations" stipulates that the mine hoisting device "must be inspected once a year and tested every three years. It can be used only after it is qualified." The test content includes the idle time of the brake, the braking deceleration, Applied brake pressure, the gap between the brake sh...

AI Technical Summary

Problems solved by technology

This method requires a large amount of modification to the disc brake, and it is inconvenient to install on site

The above two detection devices do not have the function of detecting brake clearance and braking deceleration

At the same time, these two devices are test instruments developed based on single-chip microcomputers. Their automation level is low, their data storage capacity is small, and they do not have the function of network communication, so they cannot meet the requirements of monitoring integration, digitalization and networking proposed by coal mines.
