The disc brake of the mine hoist winch is a device that directly acts on the brake wheel or brake disc near the equipment, which can generate braking torque to make the mine hoist achieve functions such as deceleration, stopping or keeping the stop state. According to the structure, it can be divided into block brake and disc brake. In essence, the working reliability of the disc brake is composed of inherent reliability and use reliability. Among them, inherent reliability refers to the inherent properties of the brake itself, and use reliability refers to the properties determined by human factors after manufacturing, which belongs to acquired factors. The working reliability of the brake can be regarded as a series product of inherent reliability and use reliability. Only when the inherent reliability and use reliability are guaranteed at the same time on site, the reliability of the entire machine can reach the goal.
At present, hydraulic disc brakes are widely used because of their advantages such as easy adjustment of braking torque, good versatility, and high safety and reliability. In recent years, accidents caused by the failure of disc brakes to stop the car have been common on site, which has posed a great threat to the safety of mine production. Comprehensive analysis and real-time monitoring of the working reliability of disc brakes will help improve the safety of mine hoisting.
