Background

Coal mines are areas where humans mine coal resources in coal-rich mining areas, and are generally divided into underground coal mines and opencast coal mines. When the coal seam is far from the ground surface, a tunnel is usually dug to the underground, so that the coal is a mineworker coal mine. When the coal seam is very close to the earth surface, the coal is generally excavated by directly stripping the earth surface, which is an open pit coal mine. The vast majority of coal mines in China belong to underground coal mines. In coal mining, a coal mine drilling machine is needed to improve the coal mine collection efficiency. However, in the coal mine drilling machine lifting adjusting device in the prior art, the downward adjusting amplitude of the drilling machine is small, and the coal mine below cannot be deeply excavated. In view of this, we propose an adjustable lifting device for a coal mine drilling rig.

Detailed Description

Referring to fig. 1-3, the present invention provides a technical solution:

the utility model provides an adjust elevating gear for colliery rig, including tractor

main part

1, 1 right-hand member of tractor main part has set firmly backup pad 2, activity groove 3 has been seted up to 2 right parts of backup pad, the inner wall left end is equipped with installing frame 4 around the activity groove 3, installing frame 4 inner wall has seted up mounting

groove

5, 5 inside movable blocks 6 that are equipped with of mounting groove, the terminal surface has all set firmly spring 7 about the

movable block

6, 6 the inner of two movable blocks has set firmly mounting

panel
