Abstract

The invention relates to the technical field of drilling equipment and discloses a drilling machine structure used for a coal mine. The drilling machine structure comprises a drilling machine body and caterpillar travelling mechanisms arranged on the two sides of the bottom of the drilling machine body. A front supporting oil cylinder is arranged on the lower side of the front end of the drilling machine body; a rear supporting oil cylinder is arranged on the lower side of the rear end of the drilling machine body; an operation table is arranged at one end of the upper side of the drilling machine body; a rotary base is arranged at the other end of the upper side of the drilling machine body and provided with two vertical double-head supporting oil cylinders; a beam is arranged between shells of the double-head supporting oil cylinders and provided with a rack which is in rotary connection with the beam and provided with a drilling assembly; and an angle adjustment oil cylinder is arranged between the bottom face of the rack and the rotary base. The drilling machine structure has the beneficial effects of stable supporting, flexible drilling and convenient operation.

Description

technical field [0001] The invention relates to the technical field of drilling equipment, in particular to a coal mine drilling machine structure. Background technique [0002] The gas content in underground coal mines is relatively high. In order to ensure safety, it is necessary to drill gas discharge holes in underground coal mines to discharge the gas. At present, there are many types of underground drilling machines in coal mines, including manual and semi-automatic drilling machines. However, manual and semi-automatic coal mining drilling machines require multiple people to cooperate, and the underground space of coal mines is complex, and the range of drilling angles is wide. Manual adjustment of drilling angles requires a lot of work. Large, low punching efficiency. In order to adapt to multi-angle drilling underground in coal mines, there is now a crawler-type automatic drilling rig that can automatically adjust the drilling angle. Drilling holes in small coal mi...
