Coal mining machine and guiding skid shoe component

Abstract

The invention relates to the mechanic field, in particular to a guiding skid shoe component, comprising a guiding skid shoe having a guide groove, a wear layer fixed on an upper surface of the guide groove, a movable measuring rod and a sensor; the guiding skid shoe comprises a mounting hole over the guide groove; the wear layer is provided with a measuring hole passing through the guide groove and the mounting hole, the movable measuring rod is located in the mounting hole, and a lower end of the movable measuring rod is in sliding fit with the measuring hole along the axial direction of the measuring hole; and the sensor is located in the mounting hole and used for measuring displacement of the movable measuring rod. With reduction of the thickness of the wear layer, the movable measuring rod gradually moves upwards, and the sensor can measure the displacement of the movable measuring rod and measure the wearing capacity of the wear layer. The sensor can conveniently and accurately measure the wearing capacity of the wear layer to perform real-time measurement on the wearing capacity of the wear layer, so that the wear layer can be repaired and the guiding skid shoe can be changed in time, and derailment of the guiding skid shoe and damage on other elements caused by excessive wearing of the wear layer are avoided.

Description

technical field [0001] The invention relates to the field of machinery, more specifically, to a guide shoe assembly. In addition, the present invention also relates to a coal shearer comprising any one of the above-mentioned guide shoe assemblies. Background technique [0002] The shearer is the core equipment of coal mining, and its main function is to break coal and load coal. The shearer in the prior art includes a guide shoe assembly, and the guide shoe assembly further includes a guide shoe and a wear-resistant layer. The guide slide The shoe has a guide groove on the upper surface of which the wear layer is fixed. When installing the shearer, set the guide groove of the guide shoe on the pin row of the conveyor, so that the guide shoe supports part of the weight of the shearer, and the shearer uses the pin row of the conveyor as the track. When the shearer is working, the shearer reciprocates on the pin row of the conveyor, so that the lower surface of the wear-resis...

AI Technical Summary

Problems solved by technology

In the prior art, regular manual measurement is used, but manual measurement cannot realize real-time monitoring, which leads to the inability to detect and timely replace the wear-resistant layer earlier, resulting in derailment and damage to other parts, and manual measurement also has cumbersome measurement operations. , inaccurate measurement results and other shortcomings
