Pick fault detection method, detection device and use method

Abstract

The invention relates to the field of intelligent coal mining equipment, in particular to a cutting tooth fault detection method, a detection device, a use method and a cutting tooth fault detection method, aiming at each cutting tooth, a detection device is correspondingly arranged, the angular position information of the cutting tooth in the cutting process is detected, a curve of the angular position changing along with time is generated, and feature recognition is carried out on the curve. The cutting tooth fault detection device comprises a cutting tooth detection unit and a maintenance terminal, the cutting tooth detection unit is arranged corresponding to each cutting tooth, the cutting tooth detection unit comprises a signal generation ring and a tooth holder, the signal generation ring is arranged outside the cutting tooth in a sleeving mode and rotates together with the cutting tooth, the signal generation ring is arranged in the tooth holder, a permanent magnet is arranged on the signal generation ring, and the signal generation ring is connected with the maintenance terminal. A Hall sensor is arranged in the tooth holder. Self-sharpening of the cutting teeth is utilized, fault and service life monitoring of a single cutting tooth is achieved, long-time work with faults of a roller of the coal mining machine is effectively prevented, the position of the faulted cutting tooth is rapidly positioned, the maintenance difficulty is reduced, the utilization rate of the cutting teeth is increased, and the operation cost of a coal mine is reduced.

Description

technical field [0001] The invention relates to the field of intelligent coal mining equipment, in particular to a method for detecting faults of a pick, a detecting device and a method for using the same. Background technique [0002] As an important part in the mining process, the pick is very easy to be damaged due to harsh working conditions. As far as the prior art is concerned, the pick is directly installed in the tooth holder, and a single pick does not have a fault detection function, so the fault of a single pick cannot be found in time, resulting in the malfunction of the coal mining drum, which seriously affects the The coal breaking efficiency of the shearer. If the method of regular batch replacement is adopted, some of the picks that have not reached their service life will inevitably be replaced together, resulting in waste of labor and materials, and increasing the operating cost of coal mines. SUMMARY OF THE INVENTION [0003] The present invention aims...

[0002] As an important part in the mining process, picks are subject to harsh working conditions and are prone to damage

As far as the existing technology is concerned, the pick is directly installed in the tooth seat, and a single pick does not have the fault detection function, so the fault of a single pick is often not found in time, resulting in the coal mining drum working with diseases, which seriously affects Shearer Coal Breaking Efficiency

If the method of regular batch replacement is adopted, some picks that have not reached their service life will inevitably be replaced together, resulting in waste of labor and materials, and increasing the operating cost of the coal mine
