DETAILED DESCRIPTION

[0020] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0021] Example 1:

[0022] This embodiment provides an arch anchor arm, such as Figure 1 As shown, the boom 1 includes a rock drilling device 2 mounted thereon. The rock drilling device 2 is rotatable along the length of the boom 1. That is, the rotation axis of the rock drilling device 2 is parallel to the length of the boom 1, and the extension of the rotation axis of the rock drilling device 2 coincides with the boom 1. The boom 1 also includes a first gripping mechanism 3 and a hanging basket 9. Of course, the boom 1 may also be provided with a separate gripping mechanism 3 or hanging basket 9.

[0023] The rock drilling device 2 can rotate around the length direction of the boom 1, that is, after the rock drilling device 2 is constructed on one side of the boom 1, it can be quickly rotated to the other side relative to the boom 1 for construction, thereby improving work efficiency; the rotation axis of the traditional rock drilling device 2 is on the outside of the boom 1, and the impact force generated by the rock drilling device 2 when working acts laterally on the boom 1, which will cause the boom 1 to bend and reduce the movement accuracy of the arch anchor arm. However, when the rotation axis of the rock drilling device 2 is aligned with the boom 1, the impact force generated by the rock drilling device 2 when working is transmitted along the direction of the boom 1, which has good bearing capacity and long service life, and the distance between the rock drilling device 2 and the boom 1 is closer, and the space occupied on the outside is less, which is conducive to use in tunnels.

[0024] To ensure reliable rotation of the rock drilling device 2, the rock drilling device 2 is connected to the boom 1 via a first slewing mechanism 4, the slewing direction of which is perpendicular to the length direction of the boom 1. The design of the first slewing mechanism 4 ensures reliable rotation of the rock drilling device 2 along the length direction of the boom 1.

[0025] To expand the operating range of the rock drilling device 2, the device is designed to rotate within a vertical plane. The device is connected to the first slewing mechanism 4 via a first connecting base 5. A second slewing mechanism 6 is provided on the side of the device 2, with the first connecting base 5 connected to the first slewing mechanism 4 and the second slewing mechanism 6, respectively. The design of the first connecting base 5 facilitates the rock drilling device 2 to avoid the first slewing mechanism 4, allowing the first slewing mechanism 4 to drive the rock drilling device 2 in rotation. The design of the second slewing mechanism 6 ensures reliable rotation of the rock drilling device 2 within the vertical plane.

[0026] In this embodiment, the first connecting seat 5 is L-shaped as a whole and is made of a square tube. The two sides of the L-shape are connected to the first rotating mechanism 4 and the second rotating mechanism 6 respectively.

[0027] To ensure a secure connection between the first slewing mechanism 4 and the boom 1, a second connecting seat 7 is provided. The first slewing mechanism 4 is located at the end of the second connecting seat 7 that is distal to the boom 1. The design of the second connecting seat 7 ensures that the operating pressure exerted on the first slewing mechanism 4 is transmitted to the boom 1 through the second connecting seat 7, ensuring reliable overall load-bearing. In this embodiment, the rotation axis of the first slewing mechanism 4 coincides with the longitudinal centerline of the boom 1.

[0028] In order to facilitate the construction of workers, Figure 2 As shown, a crossbeam assembly 8 is provided below the boom 1. One end of the crossbeam assembly 8 is connected to the boom 1, and the first gripping mechanism 3 and the hanging basket 9 are connected to the other end of the crossbeam assembly 8. The hanging basket 9 is used for workers to stand and facilitate their work. The design of the crossbeam assembly 8 allows the first gripping mechanism 3 and the hanging basket 9 to extend outward, which is more convenient for workers to operate and reduces the interference of the first gripping mechanism 3 and the hanging basket 9 with the operation of the rock drilling device 2.

[0029] To ensure the reliability of the crossbeam assembly 8, the crossbeam assembly 8 includes a third connecting seat 10, a crossbeam 11, and a driving cylinder 12. One end of the crossbeam 11 is hinged to the third connecting seat 10, the first gripping mechanism 3 and the hanging basket 9 are connected to the other end of the crossbeam 11, the third connecting seat 10 is connected to the boom 1, one end of the driving cylinder 12 is hinged to the third connecting seat 10, and the other end of the driving cylinder 12 is hinged to the crossbeam 11. The driving cylinder 12 can make the crossbeam 11 swing up and down, realizing the pitch adjustment of the first gripping mechanism 3 and the hanging basket 9.

[0030] In order to expand the working range of the hanging basket 9, the third connecting seat 10 is connected to the boom 1 via the third rotating mechanism 13; the first gripping mechanism 3 and the hanging basket 9 are connected to the crossbeam 11 via the fourth rotating mechanism 14. One side of the third rotating mechanism 13 is connected to the second connecting seat 7, and the other side is connected to the third connecting seat 10; one side of the fourth rotating mechanism 14 is connected to the crossbeam 11, and the other side is connected to the hanging basket 9 and the first gripping mechanism 3. The first gripping mechanism 3 is located on the side of the hanging basket 9 away from the boom 1. The third rotating mechanism 13 is used to drive the hanging basket 9 and the first gripping mechanism 3 to rotate around the second connecting seat 7, which can not only expand the working range of the hanging basket 9 and the first gripping mechanism 3, but also rotate to avoid the rock drilling device 2; the fourth rotating mechanism 14 is used to drive the hanging basket 9 and the first gripping mechanism 3 to rotate themselves, making it easier to adjust the working direction.

[0031] To expand the working range, the telescopic arm 15 is further provided. The boom 1 is sleeved on the telescopic arm 15 and can move relative to the boom 1. The rock drilling device 2 is located at the end of the telescopic arm 15 away from the boom 1. The first gripping mechanism 3 and the hanging basket 9 are located at the end of the telescopic arm 15 away from the boom 1. The second connecting seat 7 is located at the end of the telescopic arm 15 away from the boom 1.

[0032] In this embodiment, the first rotary mechanism 4, the second rotary mechanism 6, the third rotary mechanism 13, and the fourth rotary mechanism 14 can all utilize rotary reducers, which is a prior art and will not be further described. Of course, the gripping mechanism 3 can be replaced by a crushing mechanism; the rotation axis of the first rotary mechanism 4 and the rotation axis of the second rotary mechanism 6 are arranged perpendicularly. The rotation of the first rotary mechanism 4 can drive the rotation of the second rotary mechanism 6, thereby allowing the rotation plane of the second rotary mechanism 6 to rotate about the rotation axis of the first rotary mechanism 4.

[0033] Example 2:

[0034] This embodiment provides a rock drilling arch anchor trolley, such as Figure 3 As shown, the vehicle comprises a vehicle body 16 and an anchor arm as described in Example 1. The anchor arm is located at the front of the vehicle body 16 and is rotatably connected to the vehicle body 16. The anchor arms are symmetrically arranged. A fifth swivel mechanism 19 is provided between the anchor arm and the vehicle body 16 to drive the anchor arm's rotation. The symmetrical arrangement of the anchor arms enables simultaneous construction on both sides of the vehicle body 16, improving overall work efficiency.

[0035] For more secure gripping, a third arm 17 is positioned between the two arch anchor arms. A second gripping mechanism 18 is mounted on this arm. This arm 17 is located at the front of the vehicle body 16 and is pivotally connected to the vehicle body 16. The first gripping mechanism 3 faces each side, while the second gripping mechanism 18 faces the top, ensuring reliable gripping of the arch. The third arm 17 is used to lift the second gripping mechanism 18.
