Description

Novel guide slipper Technical Field The utility model relates to the technical field of guide sliding shoes, in particular to a novel guide sliding shoe. Background The guide sliding shoe is an important part for the coal mining machine, and the coal mining machine can move along the arrangement direction of the scraper machine through the support and the guide of the sliding shoe on the pin rail of the scraper machine. Because the contact area between the guide sliding shoe and the pin rail of the coal mining machine is limited, the surface contact area is small, the guide sliding shoe is long-time working and is easy to wear in the interior, the surface of the guide sliding shoe is treated, and the wear resistance of the inner surface of the sliding shoe is improved so as to prolong the service life of the sliding shoe. There are three ways to weld the wear-resistant plate, weld the wear-resistant material layer and surface heat treatment in the sliding boot generally, weld the wear-resistant material layer scheme and generally appear two problems: 1. If the mode of welding the wear-resistant material is adopted, the wear-resistant material is easy to collapse at the corners due to high brittleness, and the peripheral material is further influenced. 2. The surface of the wear-resistant material layer needs to be processed, so that the surface hardness is high, the processing time is long, and the processing cost is high; Through searching, the patent number CN117588211A, named as a guide sliding shoe, a coal mining machine and a guide sliding shoe manufacturing method, is relatively closest to the prior art in principle, because the patent proposes to process grooves, provide a buffer layer and a buffer part, and improve the welding firmness, but the design form cannot avoid the characteristic that the surface of a material needs to be processed, and has higher production cost. Through careful analysis, the above-mentioned patent emphasizes the fusion of materials by using layered welding of various materials to transition the materials from softer to harder materials, with emphasis on improving the firmness of the wear-resistant material. The novel structural coal mining machine sliding shoe is similar to the working principle of the patent, but the novel structural coal mining machine sliding shoe is convenient to control the height of the wear-resistant layer by processing the groove on the surface of the sliding shoe and then welding the groove, and the periphery of the wear-resistant layer is wrapped by using a material with toughness on the periphery of the groove, so that the problem that the high-hardness wear-resistant material is easy to crack after being stressed is avoided, the impact resistance of the sliding shoe is improved, the underlying buffer layer and the buffer part are omitted, the structure is simpler and more convenient, the processing procedure is reduced, and the novel structural coal mining machine sliding shoe is more convenient to process. Disclosure of utility model First technical problem The utility model aims at least solving the problems of more processing procedures, high difficulty and insufficient impact resistance in the prior art. (II) technical content The technical scheme provides a novel guide sliding shoe, which is achieved by the following specific technical means: The sliding shoe body is provided with a groove on the contact surface of the inner wall of the sliding shoe body and the pin rail; And the wear-resistant layers are provided with a plurality of groups, are placed in the corresponding grooves and are fixed, and the thickness of the wear-resistant layers is not greater than the depth of the grooves. According to the first preferred technical scheme, the wear-resistant coating is formed by welding, cladding or plug welding the wear-resistant layer around the wear-resistant layer by using a welding material, cladding material or plug welding material. In the second preferred technical scheme, the side, close to the groove, of the wrapping edge is equal to the inner wall of the sliding shoe body in height.
