A disc brake for diagnosing brake failure and monitoring braking force

Abstract

The invention discloses a disc brake capable of diagnosing a braking fault and monitoring braking force. The disc brake is characterized in that a disc spring force sensor and a braking force sensor are arranged; the disc spring force sensor is used for monitoring disc spring force generated by deformation of a disc spring set; and the braking force sensor is used for monitoring braking force applied to a brake disc by a brake shoe component. The working principle of the disc brake is as follows: under a braking state, the disc spring force is totally applied to the brake shoe; and according to experiments, friction force is very small and ignorable compared with the disc spring force, so that the braking force is equal to the disc spring force. Under the braking state, values monitored by the two sensors are compared; if the two values are equal, the value is taken as the monitored braking force; if the values are not equal, the braking fault of the disc brake is diagnosed. By adopting the disc brake capable of diagnosing the braking fault and monitoring the braking force, the braking fault can be diagnosed; the braking force monitoring precision is high; braking is reliable; and the disc brake has wide practicability.

Description

technical field [0001] The invention relates to a disc brake for diagnosing braking failure and monitoring braking force, especially suitable for the disc brake capable of diagnosing braking failure and monitoring braking force for mine hoists. Background technique [0002] Mine hoist is an important means of transportation in coal mine production, mainly used for transportation of equipment, materials and personnel, which is directly related to the life safety of miners and the safe production of coal mines. The braking performance of the brake plays a decisive role in the safe operation of the hoist, because the braking failure of the brake leads to the braking failure of the hoist, causing serious production safety accidents from time to time, especially the accurate monitoring of the braking force of the brake is very important for the hoist The safe operation of the machine plays a vital role.
