Description

Technical Field

[0002] In current tunnel support technology, anchor bolt support mostly employs a work mode of mechanical drilling, manual filling of anchoring agent, and tightening of anchor bolts. This not only leads to slow tunnel formation but also compromises worker safety because the anchor bolt support work is carried out in an elevated area. Existing anchor bolt drilling rigs suffer from low automation levels, requiring manual assistance in many stages, which increases the construction process without eliminating existing safety hazards. Furthermore, the numerous transmission components required increase the machine's failure rate, indirectly raising production costs. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] The purpose of this invention is to provide a turret-type automatic anchor bolt drilling rig for coal mines, so as to solve the problems existing in the prior art, reduce the labor intensity of workers, eliminate existing safety hazards, and at the same time increase the reliability of the equipment and improve the work efficiency.

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, the turret-type fully automatic anchor bolt drilling frame provided by the present invention includes a drilling mechanism 1, a chemical injection mechanism 3, an anchoring mechanism 5, an anchor bolt chamber 4, and a fixed support mechanism 2.

[0035] Specifically, the fixed support mechanism 2 includes a support shaft 10, a guide rail support seat 9, a guide rail support seat 7, an anchor bolt chamber support seat 8, and a rotary hydraulic motor 6. The guide rail support seat 9 and the guide rail support seat 7 are respectively installed at the upper and lower ends of the fixed support shaft 10, mainly used to support the drilling and anchor bolt guide rails; the anchor bolt chamber support seat 8 is installed in the middle of the support shaft 10, mainly used to support the anchor bolt chamber 4; the rotary hydraulic motor 6 is installed at the bottom of the support shaft, mainly used to rotate the support shaft 10, thereby driving the drilling frame position switching.

[0036] The drilling mechanism includes a first propulsion beam bracket 13, a second propulsion beam bracket 17, a first propulsion beam 15, a drill box support 12, a first propulsion beam moving hydraulic cylinder 14, a top plate 18, a hydraulic motor 11, and a chain drive mechanism 16. The first propulsion beam bracket 13 and the second propulsion beam bracket 17 are mounted on one side of the first guide rail support 9 and the second guide rail support 7. The first propulsion beam 15 is mounted on the first propulsion beam bracket 13 and the second propulsion beam bracket 17. The drill box support 12 is mounted on the first propulsion beam 15, allowing the drill box to move back and forth along the first propulsion beam 15. One end of the first propulsion beam moving hydraulic cylinder 14 is fixed to the second guide rail support 7, and the other end is fixed to the first propulsion beam 15, allowing the first propulsion beam 15 to move back and forth along the first propulsion beam bracket 13 and the second propulsion beam bracket 17. The top plate 18 is mounted at the front end of the first propulsion beam 15 and is mainly used to maintain close contact with the anchoring environment and to constrain the direction of drill rod movement during drilling. Hydraulic motor 11 is installed below the rear end of the push beam 15, mainly to provide power to the chain drive mechanism 16. The chain drive mechanism 16 is installed in the groove of the push beam 15, mainly to drive the drill box to move forward and backward along the direction of the push beam. At the drilling location, the push beam moving hydraulic cylinder 14 moves, making the roof 18 in close contact with the coal wall or rock wall. Then, hydraulic motor 11 drives chain drive mechanism 16 to move, driving the drill box and drill rod forward along the direction of the push beam 15 to complete the drilling operation. After the operation is completed, hydraulic motor 11 reverses, driving the drill box back to its initial position on the push beam 15. Then, the push beam moving hydraulic cylinder 14 retracts, causing the push beam 15 to return to its initial position.

[0037] The injection mechanism includes an injection tube 20, an injection tube fixing element 19, an injection tube fixing element 21, an injection tube moving hydraulic cylinder 22, and a connector 23. The injection tube 20 is mainly used to deliver the anchoring agent. The injection tube fixing element 19 and the injection tube fixing element 21 are respectively installed in the middle and upper parts of the drilling mechanism's propulsion beam. One end is fixed to the propulsion beam 15, and the other end connects to the injection tube 20 and the injection tube moving hydraulic cylinder 22. The injection tube moving hydraulic cylinder 22 is connected to the injection tube 20 through the injection tube fixing element 19, the injection tube fixing element 21, and the connector 23, and is mainly used to feed the injection tube 20 into the anchor hole. The connector 23 has two through holes, an upper through hole for installing the injection tube 20, and a lower through hole for installing the injection tube moving hydraulic cylinder 22. The injection tube fixing element 19 and the injection tube fixing element 21 are designed with a certain inclination angle. The inclination angle can be determined according to the distance between the drilling position and the anchoring position and the height of the drill box and the anchor box, so as to ensure that the drill rod, anchor rod and injection tube are on the same circumference (the same distance from the support shaft 10), so that the position can be switched by rotating the support shaft 10. When it is necessary to fill the anchoring agent, the drilling mechanism push beam moving hydraulic cylinder 14 moves to push the injection tube 20 to the anchor hole. Then the injection tube moving hydraulic cylinder 22 retracts, pushing the injection tube 20 into the anchor hole. After the anchoring agent is filled, the injection tube moving hydraulic cylinder 22 extends, and then the push beam moving hydraulic cylinder 14 retracts, so that the injection tube 20 exits the anchor hole and returns to the initial position.

[0038] A further preferred embodiment of the anchoring mechanism includes a third propulsion beam bracket 25, a fourth propulsion beam bracket 29, a second propulsion beam 30, an anchor box support 24, a second propulsion beam moving hydraulic cylinder 32, an anchor clamp 28, a second hydraulic motor 31, a second chain drive mechanism 26, and an anchor clamping mechanism 27. The third propulsion beam bracket 25 and the fourth propulsion beam bracket 29 are mounted on the other side of the first guide rail support 9 and the second guide rail support 7, respectively. The second propulsion beam 30 is mounted on the third propulsion beam bracket 25 and the fourth propulsion beam bracket 29. The anchor box support 24 is mounted on the second propulsion beam 30, allowing the anchor box to move back and forth along the second propulsion beam 30. One end of the second propulsion beam moving hydraulic cylinder 32 is fixed to the second guide rail support 7, and the other end is fixed to the second propulsion beam 30, allowing the second propulsion beam 30 to move back and forth along the third propulsion beam bracket 25 and the fourth propulsion beam bracket 29. The anchor clamp 28 is mounted at the front end of the second propulsion beam 30 and is mainly used to maintain the stability of the anchor during the anchor installation process. Hydraulic motor 21 is installed below the rear end of propulsion beam 20, mainly to provide power to chain drive mechanism 26. Chain drive mechanism 26 is connected to hydraulic motor 21 and installed in the groove of propulsion beam 20, mainly to drive anchor box forward and backward along propulsion beam 20. Anchor bolt grabbing mechanism 27 is installed in the middle of propulsion beam 20, mainly to remove anchor bolts from anchor bolt chamber 4 and onto anchor box, and to assist in anchor bolt stability during installation. Anchor bolt grabbing mechanism 27 includes connecting rod 41, grabbing device 1 40, grabbing device 2 43, and beam connecting seat 42.

Clamp claw 1 46 and clamp claw 2 47 are fixed to clamp seat 50 via clamp pin 1 45 and clamp pin 2 48. When anchor bolt clamp 28 is working, hydraulic cylinder 44 extends rack 49 to open the clamp, and hydraulic cylinder 44 retracts the clamp to tighten it. Clamp claw 1 46 and clamp claw 2 47 have the same structure, with a semi-circular groove at the front end for clamping the anchor bolt, and a semi-circular gear at the rear end for meshing with rack 49. Additionally, a through hole is machined to connect the clamp pin and allow rotation around it.Once the anchor bolt is secured, the anchor bolt gripping mechanism 27 grips the anchor bolt to the front end of the anchor box. Then, the second hydraulic cylinder 32 moves, causing the anchor bolt clamp 28 to come into close contact with the external environment. Afterward, the second hydraulic motor 31 drives the second chain transmission mechanism 26 to move, causing the anchor box to move forward along the direction of the second propulsion beam 30. After the securing is completed, the second hydraulic motor 31 reverses, causing the anchor box to return to its initial position on the second propulsion beam 30. Then, the second hydraulic cylinder 32 retracts, causing the second propulsion beam 30 to return to its initial position.

The bolt groove plate 1 38 is fixed to the upper part of the rotating shaft 36, and the bolt groove plate 2 35 is fixed to the lower part of the rotating shaft 36, mainly used to move the bolts to the bolt gripping mechanism 27. The ratchet mechanism 33 is installed at the lower end of the rotating shaft 36, converting the rotational motion of the support shaft 10 into the rotational motion of the bolt magazine rotating shaft 36, thereby driving the bolts to the bolt gripping mechanism 27. The bolt base 39 is mainly used to hold the bolts 37 and moves synchronously with the bolts, preventing the tray from being scratched or damaged by the bolts. The ratchet mechanism 33 is mainly used to transmit the rotational motion of the support shaft 10 to the rotating shaft of the anchor bolt chamber 4. It mainly includes a ratchet 54, a pawl 56, a telescopic rod 58, a spring 57, a first connecting rod 51, a ratchet disc 55, a connecting pin 52, and a second connecting rod 53.

The second connecting rod 53 has through holes in the middle and on one side; the middle through hole connects to the rotating shaft 36, and the other through hole connects to the second connecting rod 53 via the connecting pin 52. The first connecting rod 51 is installed on the guide rail support seat 7. The anchor bolt base 39 is mainly used to hold the anchor bolts and moves synchronously with the anchor bolt 37 as it rotates, preventing the tray 34 from being scratched or damaged by the anchor bolts. After the drilling-injection-anchoring anchor installation is completed, the support shaft 10 rotates, driving the guide rail support seat 2 7 back to its initial position. The connecting rod 1 51 and connecting rod 2 53 in the ratchet mechanism 33 rotate accordingly. The telescopic rod 58 and spring 57 drive the pawl 56 and ratchet 54 to rotate. In turn, the rotating shaft 36 of the anchor bolt chamber, the anchor bolt groove 1 38, the anchor bolt groove 2 35 and the anchor bolt base 39 rotate at the corresponding angle, driving the anchor bolt 37 to the anchor bolt gripping mechanism 27.
