Abstract

The invention discloses a fault monitoring method and device for a coal mining machine brake, and relates to the technical field of coal mines. The method and the device mainly aim to solve the problem that the fault processing efficiency of a coal mining machine brake is low due to the fact that the maintenance time and maintenance target of an existing coal mining machine brake cannot be accurately determined. The method mainly comprises the following steps of acquiring monitoring state data for monitoring the brake in the coal mining process of the coal mining machine; comparing the monitoring state data with a preset state threshold value, and analyzing running state information of the coal mining machine brake according to a comparison result; and if the running state information is sub-abnormal state information, monitoring the monitoring state data based on an established fault monitoring model to obtain a fault monitoring result, and outputting the fault monitoring result. The method and the device are mainly used for fault monitoring of the coal mining machine brake.

Description

technical field

[0001] The invention relates to the technical field of coal mines, in particular to a fault monitoring method and device for a coal shearer brake. Background technique

[0002] The coal mining industry has always been the lifeline industry in my country's economy. With the rapid development of technology today, advanced technologies such as unmanned and intelligent are gradually replacing the original manual operation methods, especially in the coal mining industry. The machine completes the original manual coal mining operation. Among them, the brake is an important safety braking device of the shearer, and its performance and braking response speed are directly related to the safety and braking efficiency of the shearer. The brake is to rely on the mutual extrusion and friction of the friction plate inside the brake and the brake plate to convert the inertial kinetic energy of the shearer into the internal energy of friction, so that the position of the she...
