Split-type guiding sliding shoe

Abstract

The invention relates to a split-type guiding sliding shoe, which includes a main sliding shoe and a bottom hook. A left-right extending guiding groove is formed in the front part of a main sliding shoe base of the main sliding shoe, an opening in the lower part of the guiding groove is in left-right penetrating, the surface of the guiding groove is provided with a front wear-resisting layer, a top wear-resisting layer and a rear wear-resisting layer which are successively connected in a head-to-tail mode. The bottom hook comprises a bottom hook base and two bottom hook convex stretching partsformed on the left part and the right part of the bottom hook base. The left part and the right part of the bottom hook are correspondingly connected with the left part and the right part of the rearpart of the main sliding shoe base in a top-to-bottom inserted mode. Positioning blocks are inserted in the front-rear direction of the inserted-connection parts correspondingly. Dowels are insertedin and fixed to the interfaces between the positioning blocks and themain sliding shoe in the left-right direction correspondingly. A bottom hook wear-resisting layer is arranged on the part, forwardbeyond the rear part of the main sliding shoe base, of the top face of thebottom hook base, and the front wear-resisting layer, the top wear-resisting layer, the rear wear-resisting layer and the bottom hook wear-resisting layer are successively arranged to enclose a square frame opening. The split-type guiding sliding shoe can be used for a drum-type mining machine for exploiting high-hardness and high-abradability mine materials, and the problems of short service life of a guiding sliding shoe and serious equipment wear are solved.

Description

technical field [0001] The invention relates to a guide shoe of a mining machine, which is a split structure, and is mainly suitable for use environments and occasions where the guide shoe wears seriously, such as mining high-hardness and / or highly abrasive mineral materials, etc., and belongs to underground mining. field of mechanical technology. Background technique [0002] For the mining method of using the drum mining machine to mine high-hardness mineral materials, the upward trend of the machine body is greatly increased due to the reaction force generated by cutting the hard mineral material, and the lower wear-resistant layer of the guide shoe of the mining machine walking system is severely worn . If the abrasiveness of the mined material is very high, the wear of the lower wear-resistant layer will be aggravated, resulting in a very low service life of the guide shoe and a significant shortening of the service life of the walking transmission system. The equipme...
