The invention relates to the technical field of drilling machines and discloses a drilling machine rack angle adjustment and positioning mechanism which comprises a base. The base is provided with two parallel stand columns; a beam is arranged between the stand columns and provided with a rack which is in rotary connection with the beam; the base is provided two supporting rods and connected with the lower ends of the supporting rods through hinge bases; the two supporting rods are both provided with hoops and in slide connection with the hoops; the two hoops are connected through a connecting rod; the bottom of the rack is provided with a supporting base which is in rotary connection with the connecting rod; hydraulic locking mechanisms are arranged between the hoops and the supporting rods correspondingly; and an angle adjustment oil cylinder is arranged between the bottom face of the rack and a rotary base. The drilling machine rack angle adjustment and positioning mechanism have the beneficial effects of convenient drill bit assembly angle adjustment, flexible drilling and good stability.
Description
technical field [0001] The invention relates to the technical field of drilling rigs, in particular to a drilling rig frame angle adjustment and positioning mechanism. 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 whose drill bit assembly structure can automatically adjust th...
