Hole-finding angle adjusting mechanism for jumbolter

Abstract

The invention discloses a hole-finding angle adjusting mechanism for a jumbolter. The hole-finding angle adjusting mechanism comprises a sliding frame assembly, a power assembly, a drill boom and twoswing mechanisms, wherein the power assembly comprises a hydraulic motor, a speed reducer, a propelling oil cylinder, a drill rod and a drill bit, the propelling oil cylinder is arranged on the rear portion of the sliding frame assembly, the hydraulic motor is connected with the speed reducer and connected to the propelling oil cylinder through a supporting base, the supporting base is slidably arranged on the rear portion of the sliding frame assembly, the speed reducer is sequentially connected with the drill rod and the drill bit, the drill rod penetrates through a front base of the slidingframe assembly, the front end of the drill arm is connected with the rear portion of the sliding frame assembly through one swing mechanism, the rear end of the drill arm is connected with a connecting base through one swing mechanism, and the connecting base is used for connecting with a main chine. According to the hole-finding angle adjusting mechanism for the jumbolter, the problem that whenan existing jumbolter drills a hole, hole position finding is difficult is solved, the power assembly of the jumbolter can be operated to drill an anchor rod hole or an anchor cable hole after preliminary rough and accurate hole finding, hole finding operation is easy, time is short, and precision and efficiency are high.

Description

technical field [0001] The invention relates to the technical field of roadway drilling rock bolts, in particular to a hole-seeking angle adjustment mechanism for a rock bolt. Background technique [0002] At present, in the roadway excavation construction process in our country, most of the roadways adopt the support form of hanging nets and spray paddles, and the hanging nets must be fixed on the top of the roadway or the two side walls through anchor bolts and cables. It is used to drill anchor rod and anchor cable holes, and after drilling, push the anchor rod and anchor cable into the anchor rod hole or anchor cable hole and perform the locking operation of the anchor net. [0003] And the existing rock bolt rig is all by adjusting the drill arm or The angle of the telescopic boom can be adjusted to achieve the required angle parameters. Since the drill boom or the telescopic boom is farther away from the propulsion assembly on the carriage of the rock bolter, both the...

Problems solved by technology

[0003] And the existing rock bolt rig is all by adjusting the drill arm or The angle of the telescopic boom can be adjusted to achieve the required angle parameters. Since the drill boom or the telescopic boom is farther away from the propulsion assembly on the carriage of the rock bolter, both the boom and the carriage assembly are larger in size and heavier in weight. Especially when the bolt hole at the top of the roadway is turned to the second anchor hole or from the second anchor hole to the top anchor hole, the center of gravity of the rock bolt rig changes greatly, so the adjustment process is difficult and time-consuming, resulting in The drilling accuracy is not high and the efficiency is low
