Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of drilling machinery equipment, and particularly relates to a coal mine caterpillar full-hydraulic gallery drilling machine. BACKGROUND

[0002] The coal mine caterpillar full-hydraulic gallery drilling machine is a main drilling equipment for mining operation in a mine gallery, and is mainly used for surveying the strike and thickness of a coal mine, extracting gas in the coal mine, and water injection and grouting in a coal seam, and is now widely applied to the drilling operation of a gallery in a coal mine and other underground engineering.

[0003] The existing gallery drilling machine generally adopts a discrete design concept of "one function one power", that is, independent driving sources are respectively configured for the rotation angle adjustment, height adjustment and drilling feed of the drilling machine. This design mode will lead to a bulky equipment structure and complex pipeline arrangement. In the coal mine gallery with extremely limited space, the large driving assembly not only occupies valuable space, but also increases the difficulty of equipment passability and deployment. Multiple power sources mean higher manufacturing cost, more complex control system and multiplied failure points, so that the maintenance complexity and later operation and maintenance cost are high. Finally, the coordination of various actions is poor, the operation process is cumbersome, and the operator needs to control multiple switches or valve groups to complete the alignment of the drilling machine, which is low in efficiency and cannot meet the agility requirement of modern high-efficiency mining operation.
