Problems solved by technology

[0003] Such as the Chinese Patent No.: 200720102731.2 disclosed crawler-type liftable roof anchor bolt anchor cable construction drilling rig, there are two drilling rig devices, one advance support, crawler-type walking mechanism; The drilling rig platform is installed on the frame; there is a coal pushing shovel plate at the front part of the crawler walking part under the drilling rig platform; a hydraulic cylinder type advance support is installed at the front end of the platform, and one side of the advance support is equipped with a The hydraulic drilling rig for roof anchor and anchor cable; the hydraulic drilling rig for roof anchor and anchor cable construction adopts double columns, and the slideways of the left and right moving parts are installed on the double columns, and the hydraulic drilling rig rotates left or right; The hydraulic drilling rig for cable construction is installed on the middle side of the drilling rig platform, or on the left side, or on the right side. On the slideway, the oil cylinder installed on the drilling rig platform pushes the drilling rig to move back and forth as a whole. The construction drilling rig uses the column lifting device, the beam slideway and the swinging device to complete the lifting, left and right movement and swing angle of the hydraulic rock bolter rig, so as to It meets the construction requirements, but the disadvantage of this construction drilling rig is that the hydraulic rock bolter can only construct upwards, leftwards or rightwards, and cannot construct forwards, and cannot adapt to the construction of gas discharge holes, gas prediction holes, Requirements for geological drilling and water exploration holes; technical personnel in the field are also constantly trying to solve this problem, but most of the equipment on the market is complex in structure, high in cost, and troublesome to disassemble and maintain when problems occur. , there is an urgent need for a new technical solution to solve this technical problem

Embodiment 1

[0018] see figure 1 — image 3 , a drill arm device of a two-arm hydraulic rock bolt drilling rig, the drill arm device comprises a drill arm hinge seat 1, an outer cylinder of a telescopic arm 2, a telescopic oil cylinder 3, a clearance adjustment block 4, a telescopic arm 5, and a drill arm support oil cylinder 6. Adjusting oil cylinder 7, propulsion mechanism 8, drill arm swinging oil cylinder 9, drill arm fixing support 10, the telescopic oil cylinder 3 is arranged between the telescopic arm 5 and the telescopic arm outer cylinder 2, and the telescopic arm outer cylinder 2 passes through. The pin shaft is pivotally connected with the drill arm hinge seat 1, and the drill arm hinge seat 1 is fixed on the drill arm fixed support 10 through the pin shaft; the drill arm support oil cylinder 6 is respectively connected with the drill arm hinge seat 1 through the pin shaft. Connected to the outer cylinder 2 of the telescopic arm, the adjusting oil cylinder 7 is respectively con...

Embodiment 2

[0020] see figure 1 — image 3 , as an improvement of the present invention, the telescopic arm 5 and the adjusting oil cylinder 7 are parallel, which facilitates the control of the propulsion mechanism 8 .

Embodiment 3

[0022] see figure 1 — image 3 , as an improvement of the present invention, the drill arm also includes a clearance adjustment block 4, the number of the clearance adjustment block is 4, and the upper, lower, left and right sides of the front end of the outer cylinder 2 of the telescopic arm are provided with Gap adjustment block, the function of the gap adjustment block is to adjust the gap between the outer cylinder of the telescopic arm and the telescopic arm.

[0023] How it works: as figure 1 As shown in the figure, when the hydraulic rock bolt drilling rig operates at a high position, the drilling arm support cylinder 6 feeds oil and pushes the outer cylinder 2 of the telescopic arm to raise; the telescopic arm 5 is extended through the telescopic oil cylinder 3 and the adjustment oil cylinder 7, Push the propulsion mechanism 8 up to the working height, adjust the oil return of the oil cylinder 7 and pull the propulsion mechanism 8 to rotate around the upper pin of th...
