Rail

Abstract

The invention relates to a rail comprising a plurality of rail units and a rail base. The rail units are sequentially arranged left and right. The ends, close to each other, of every two adjacent railunits are connected through the same rail base. Each rail unit comprises a front vertical plate, a rear vertical plate and a plurality of rail teeth which are connected between the front vertical plate and the rear vertical plate and distributed at intervals in the left-right direction. The bottom face and the front side face of the front vertical plate are both arranged to be hardened surfaces,the upper portion of the rear vertical plate is provided with a step protruding backwards, and the top face of the rear vertical plate, the rear side face of the step and the bottom face of the step are all arranged to be hardened surfaces. The adaptability of the guide system of the drum-type mining machine to high-hardness and high-lumpiness mineral aggregate can be improved, rapid abrasion andcrushing of the guide system are avoided, and the fault processing time is short.

Description

technical field [0001] The invention relates to a track on which a mining machine can walk and slide, and is especially suitable for the situation that the mineral material is in the form of a block, and the existing guide shoes are worn obviously, especially the bottom hook of the existing guide shoes is seriously worn. , belonging to the technical field of well mining machinery. Background technique [0002] When a drum mining machine is used to mine high-hardness ore, the reaction force (especially the impact) generated by cutting the hard ore has a great impact on the mining machine's walking meshing system, and the larger ore makes the mining machine walk and meshing system. The adaptability (the faster the contact surface wears, the crush, etc. caused by the eccentric load, the worse the adaptability) faces severe tests, such as Figure 12 The walking meshing system of the existing structure shown, when encountering high hardness at the track and the large accumulated ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a track, which can solve the problem of the adaptability of the walking meshing system of the drum mining machine to high-hardness and high-agglomeration mineral materials, and avoid the rapid wear and tear of the walking meshing system under such conditions, and the need for a large number of replacements The problem
