Description

Technical Field

[0001] The utility model relates to the technical field of coal mining, in particular to a climbing device for a large-height coal mining machine. Background Art

[0002] The coal mining machine cuts back and forth in the fully mechanized mining face. The installation position of the crusher varies according to the working face conditions and the thickness of the coal seam. Different working faces adopt different installation positions. Specifically, there are two mounting holes near the top of the coal mining machine shell, and four groups (two in each group) of mounting holes on the side of the coal mining machine shell, with a total of ten mounting holes for installing a crusher. Generally, the crusher installation position is located on both symmetrical sides of the coal mining machine. Therefore, mounting holes for installing the crusher are reserved on both symmetrical sides of the coal mining machine shell.

[0003] In addition, as the thickness of the coal seam mined in the large-height fully-mechanized mining face increases, the difficulty of regular maintenance of the coal mining machine also increases accordingly. Since the working platform is also a certain distance from the ground, a series of problems arise during the operation. For example, after the mining height increases, the working face support also increases, resulting in an increase in the center of gravity of the support used for climbing, which is prone to overturning. At the same time, each maintenance requires the construction of a platform, which wastes manpower, material resources and a lot of time. The constructed platform cannot move with the coal mining machine, making it inconvenient to use. Utility Model Content
