Guiding sliding shoe of coal cutter walking part

Abstract

The invention relates to a guiding sliding shoe of a coal cutter walking part, which is engaged with a pin row of a conveyer to allow a walking wheel to roll on the pin. The guiding sliding shoe is characterized by comprising a guiding sliding shoe hook and a guiding sliding shoe plate which are respectively connected with the main body of the coal cutter, wherein the guiding sliding shoe hook and the guiding sliding shoe plate are clamped at two sides of the walking wheel of the coal cutter walking part. Because of being separately equipped in the guiding sliding shoe provided by the invention, the guiding sliding shoe hook and the guiding sliding shoe plate can be separately installed and replaced easily. And by increasing the widths of the guiding sliding shoe plate and the guiding sliding shoe hook, the invention enables the guiding sliding shoe to be endowed with increased strength and prolonged service life.

Description

technical field [0001] The invention relates to a guide slide shoe, in particular to a guide slide shoe used for the running part of a coal mining machine. Background technique [0002] The walking part of the shearer is the action pushing mechanism of the shearer, which not only plays the role of supporting the total weight of the shearer, but also has a guide shoe to mesh with the pin row of the conveyor, and rolls on the pin row through the walking wheel Drive the shearer to move. Since the guide shoe hook and the guide shoe plate of the guide shoe are subjected to the tension, compression and bending stress of the pin row during the working process, and often rub against the surface of the pin row, the guide shoe is very easy to wear, so that the It is prone to cracks and breaks and needs to be replaced frequently. [0003] See figure 1 As shown, however, on the existing coal mining machine walking part, the guide shoe hook 2 and the guide shoe plate 1 of the guide sh...

Problems solved by technology

[0003] See figure 1 As shown, however, on the existing coal mining machine walking part, the guide shoe hook 2 and the guide shoe plate 1 of the guide shoe are usually produced as a whole, so any part of it will need to be replaced if it wears out The entire guide shoe brings great material waste and increases the maintenance cost of the shearer
