Problems solved by technology
[0002] In the related technology, the coal shearer is supported on the pin rail of the scraper machine through the guide shoe assembly of the walking part, and the road wheel is engaged with the pin rail for transmission. The guide shoe assembly plays a supporting and guiding role, and the guide shoe is In addition, the wear-resistant plate of the guide shoe is welded on the guide shoe assembly, and the wear-resistant plate will be worn when the shearer is running. When the wear is serious, the wear-resistant plate needs to be replaced, otherwise It will cause damage to the walking wheel. Because the traditional guide shoe assembly is an integral casting, the wear plate is directly welded to the guide shoe assembly. It is inconvenient to replace the wear plate. It is necessary to directly replace the guide shoe assembly and disassemble the road wheel. Therefore Can lead to increased replacement time and cost

The invention provides a guide foot assembly and a coal mining machine. The guide foot assembly comprises a guide foot base, a guide foot fixing rack and assembling pins, wherein the guide foot base is detachably assembled at a walking part of the coal mining machine and provided with first-type assembling holes; the guide foot fixing rack comprises two buckled semi-ring connecting lugs, and second-type of assembling holes matched with the first-type assembling holes are formed in the semi-ring connecting lugs; the assembling pins penetrate through the first-type assembling holes and the second-type assembling holes and are used for assembling and fixing the guide foot base and a guide foot fixing seat. According to the technical scheme, a guide foot is conveniently detached and assembled, meanwhile, the structure of the guide foot fixing rack is strengthened, the adaptability between the guide foot and the guide foot assembly is enhanced by means of the waist-shaped holes, and accordingly, the structural reliability of the guide foot assembly is improved.
Description
technical field [0001] The invention relates to the technical field of coal shearers, in particular to a guide shoe assembly and a coal shearer. Background technique [0002] In the related technology, the coal mining machine is supported on the pin rail of the scraper machine through the guide shoe assembly of the walking part, and the traveling wheel is engaged with the pin rail for transmission. The guide shoe assembly plays a supporting and guiding role, and the guide shoe is In addition, the wear-resistant plate of the guide shoe is welded on the guide shoe assembly, and the wear-resistant plate will be worn when the shearer is running. When the wear is serious, the wear-resistant plate needs to be replaced, otherwise It will cause damage to the walking wheel. Because the traditional guide shoe assembly is an integral casting, the wear plate is directly welded to the guide shoe assembly. It is inconvenient to replace the wear plate. It is necessary to directly replace t...
