Description

Technical Field

[0001] This invention relates to the field of anchor drilling rig technology, specifically to an anchor drilling rig for coal mines. Background Technology

[0002] Anchor bolt drilling rigs are specialized drilling equipment designed for reinforcement projects. In coal mine engineering, anchor bolt drilling rigs are used to reinforce the tunnel walls. By fixing the roof mesh to the tunnel wall with anchor bolts, the stability and safety of the tunnel are enhanced. Traditionally, the roof mesh is placed manually on top of the support structure, which then pushes the roof mesh onto the tunnel wall. The drilling rig then drills holes in the tunnel wall. After drilling, a testing rod is inserted into the borehole to test the soil layer inside. After testing, the anchor bolts are placed into the borehole, and the nuts on the anchor bolts are tightened to fix the roof mesh. The spacing between the anchor bolts used to fix the roof mesh is 1.2m to 1.5m.

[0003] In existing technologies, after the anchor drilling rig pushes the top mesh onto the tunnel wall, it first drills a hole in the tunnel wall. The drilling rig rotates to one side, and the detection rod rotates to the bottom of the hole before penetrating deeper into the hole to test the soil layer. After the test is completed, the detection rod rotates to one side again, and the anchor drilling rig is rotated to the bottom of the hole to fix the top mesh with anchor rods. This process of repeated rotation is time-consuming, and the switching between anchor rod fixing, detection rods, and drilling rods does not maximize work efficiency. Summary of the Invention

[0013] The working principle and beneficial effects of this invention are as follows: In this invention, a conveying mechanism is installed, and a cylinder drives the gripping tube to move downwards. After the magnet on the gripping tube attracts the top net, motor two drives threaded rod one to rotate. Threaded rod one drives the supporting square tube, gripping support plate, cylinder, gripping tube, and top net to move towards the conveyor belt. Motor three starts, driving the conveyor shaft and conveyor belt to rotate. The top net falls onto the conveyor belt and moves towards the support mechanism. At the same time, the lifting frame starts, driving the lifting plate to move upwards, which in turn drives the top net to move upwards, making it easier for the gripping tube to grab the next top net. This avoids manually placing the top net on the support mechanism and improves work efficiency. In this invention, by installing a support mechanism, the conveyor belt transports the top net to the support rod, and the branch pipe will lock the top net. The hydraulic cylinder two drives the hydraulic rod two to extend and retract, pushing the top net against the tunnel wall. At the same time, when fixing the top net to the tunnel walls on the left and right sides, the motor four is started, and the motor four drives the rotating shaft three to rotate. The rotating shaft three drives the hydraulic cylinder two, the hydraulic rod two, the support rod and the top net to rotate. Then the hydraulic cylinder two drives the hydraulic rod two to extend and retract, and the hydraulic rod two drives the support rod to push the top net against the tunnel wall, preventing the top net from detaching from the support rod. In this invention, by installing a drilling mechanism, motor nine drives threaded rod two to rotate, and threaded rod two simultaneously drives connecting block to move. Connecting block drives support base, cylinder one, shaft one, motor one, hydraulic rod one, fixing block one, and drilling assembly to a suitable position. Motor one then drives shaft one to rotate, and shaft one drives cylinder one, hydraulic rod one, and drilling assembly to rotate to a suitable position. Motor five then rotates, driving fixing block, connecting column, and drilling base plate to rotate, ensuring the drill rod, detection rod, and fixed drill bit are perpendicular to the tunnel wall. Simultaneously, electric shock seven drives drilling base plate to a suitable position. Motor six then starts, and cylinder one drives hydraulic rod one to extend and retract, providing thrust to motor six and drill rod, creating the first hole in the tunnel wall. Motor nine then rotates, driving threaded rod two to rotate... Rotating rod two causes motor six to drive the drill rod and drilling bit to rotate. Simultaneously, hydraulic cylinder one drives hydraulic rod one to extend and retract, providing a thrust to motor six and the drill rod to make a second hole at the next point. At the same time, the detection rod extends into the first hole for inspection. Correspondingly, as motor six drives the drill rod and drill bit to rotate, a third hole is made at the next point. The detection rod inspects the second hole. At the same time, motor eight drives the fixed drill bit to rotate, fixing the anchor rod in the first hole. This process continues. Correspondingly, while the drilling bit is making holes, the water pump starts, injecting water into the drill rod through the water supply pipe and rotating water ring, and cooling the drilling bit through the water spray holes. This saves the time of switching back and forth between the drill rod, detection rod, and fixed drill bit, and ensures the spacing between the anchor rods, improving work efficiency. In this invention, by installing a conveying mechanism, a support mechanism, and a drilling mechanism in coordination, the problem that anchor bolt fixing is time-consuming and the work efficiency is not maximized in the prior art is solved.

Motor 9 51 drives threaded rod 2 50 to rotate, simultaneously moving connecting block 52. Connecting block 52 then moves support base 4, hydraulic cylinder 1 7, shaft 1 5, motor 1 6, hydraulic rod 1 8, fixing block 1 9, and drilling components to the appropriate positions. Motor 6 drives shaft 5 to rotate. Shaft 5 then drives cylinder 7, hydraulic rod 8, and drilling components to rotate to the appropriate position.
