Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of anchor rod setting, specifically refers to a coal mine automatic anchor rod setting device. BACKGROUND

[0002] Anchor rod is the most basic component of roadway support in contemporary coal mine. After the roadway excavation in coal mine, the stress of surrounding rock mass is redistributed, which is easy to cause deformation or collapse. By deepening into the rock mass (usually 3-6 meters), the anchor rod anchors the surface broken rock mass and the deep stable rock mass into a whole, forming a "composite beam" or "reinforced arch", thereby reinforcing the surrounding rock and preventing collapse.

[0003] The existing anchor rod drill is usually held by hand when in use, and the drill bit of the anchor rod is aligned with the positioning point for direct drilling. However, the common equipment on the market is provided with an operating handle on the motor, and the anchor rod is connected to the output end of the motor. Since there is no guiding device, the anchor rod is easy to deviate due to vibration and other external factors during setting, which causes the anchor rod to deviate from the predetermined angle, resulting in poor contact between the anchor rod and the surrounding rock mass, thereby affecting the anchoring force and the protection effect.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0027] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0028] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0029] Example 1

[0030] Combined with appendix Figure 1 , Figure 2 , Figure 4 and Figure 6As shown, an automatic rock bolt driving device for coal mines includes a rock bolt driving machine body 1 and a guide mechanism for restricting the movement of the rock bolt driving machine body 1. The guide mechanism includes symmetrically arranged base plates 2, each with symmetrically arranged connecting holes 21. The two base plates 2 are connected by a connecting plate 3. A support frame 4 is connected to the base plates 2, and a limiting rod 5 is fixedly mounted on the support frame 4. A sliding member 6 is slidably sleeved on the limiting rod 5. A guide rod 7 is connected between the two sliding members 6 through an angle adjustment assembly. One side of the rock bolt driving machine body 1 is connected to the guide rod. 7. The connecting tube 8 is adapted. The angle adjustment assembly includes a rotating part 9 connected to one end of the guide rod 7. The sliding part 6 is connected to a fixed tube 10 through a connecting rod. The rotating part 9 is rotatably disposed between two fixed tubes 10. One side of the rotating part 9 is provided with a gear 11, and the other side is connected with a spring 12. On the inner wall of one of the fixed tubes 10 near the gear 11, there are several positioning teeth 13 arranged in a circular array to cooperate with the gear 11. These positioning teeth 13 form a structure that meshes with the gear 11. One end of the spring 12 is connected to the inner wall of the other fixed tube 10.

[0031] By passing bolts through the connecting hole 21, the guide mechanism is fixed at the required installation position. When the anchor rod needs to be installed, the angle of the guide rod 7 is first adjusted according to the actual needs. The rotating part 9 is pressed towards the spring 12, and the compressed spring 12 causes the gear 11 to disengage from the tooth groove formed by several positioning teeth 13, so as to adjust the angle of the guide rod 7. After adjusting to the required angle, the spring 12 pushes the rotating part 9 back to its original position, so that the gear 11 engages with the positioning teeth 13, and the position of the guide rod 7 is fixed to ensure stability during use.

[0032] At the same time, combined with the appendix Figure 4 and Figure 6 As shown, the outer wall of the rotating component 9 is provided with an indicator arrow 14, and the outer wall of the fixed tube 10 is provided with an angle marking line 15. By indicating the angle marking line 15 through the indicator arrow 14, the angle adjusted by the guide rod 7 can be intuitively understood.

[0033] Combined with appendix Figure 1 and Figure 3 As shown, a second spring 18 is connected to the support frame 4. The second spring 18 is sleeved on the outside of the limiting rod 5, and one end of the second spring 18 is connected to the bottom surface of the sliding member 6. The second spring 18 enables the guide rod 7 to automatically return to its original position when not in use, making it convenient for the next operation. The support frame 4 is provided with symmetrical grooves 19. Slider 20 is provided on both sides of the sliding member 6 and slides within the grooves 19. The grooves 19 restrict the movement trajectory of the sliding member 6, ensuring the smooth movement of the guide rod 7.

[0034] Example 2

[0035] During the installation of anchor bolts, vibrations from the motor may cause the guide mechanism to deviate, affecting the installation effect. Based on Example 1, and in conjunction with the attached... Figure 1 , Figure 5 and Figure 6 As shown, the guide rod 7 has multiple slots 16 arranged in a circular array. The inner wall of the connecting pipe 8 is provided with a block 17 that matches the slot 16. The number of blocks 17 is the same as the number of slots 16. The block 17 and the slot 16 cooperate to firmly fix the anchor bolt machine body 1 and prevent the anchor bolt machine body 1 from shifting during operation. Rubber pads are attached to the inner wall of the connecting pipe 8 where there are no blocks 17. The rubber pads can absorb some of the vibration generated during operation. Multiple dampers 22 are arranged in an array on the base plate 2. The bottom surface of the support frame 4 is connected to one end of the damper 22. The damper 22 absorbs the vibration generated during operation and prevents the guide mechanism from shifting due to vibration during the bolting process.

[0036] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
