[0003] In existing rock splitters, the position of the splitting arm (the working end of the rock splitter) is not adjustable, limiting splitting operations to a fixed position. This results in poor adaptability to complex rock shapes or rock fissures with different orientations. Furthermore, the position of the splitting arm can only be adjusted by changing the overall position of the rock splitter, making it difficult to efficiently split complex rock shapes or rocks with different orientations, leading to low construction efficiency. Therefore, inventing a rock splitting device with an adjustable splitting arm position is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0032] In embodiments of this utility model, such as Figures 1 to 4 As shown, the adjustable arm splitting device includes a rotating support 1 and a splitting body 2; wherein,
[0033] The cross-sectional shape of the rotating support 1 is annular, see [reference]. Figure 3 The rotating bracket 1 is rotatably mounted on the mounting body. In this embodiment, the mounting body can be a robotic arm or a needle beam used to support the trolley. The rotating bracket 1 can rotate on the robotic arm or the needle beam. A guide arm 12 is provided on the outer side wall of the rotating bracket 1. The free end of the guide arm 12 extends away from the center of the rotating bracket 1 to form an adjustable arm structure.
[0034] The splitting body 2 is slidably mounted on the guide arm 12 along the length of the guide arm 12, so that the splitting body 2 can rotate around the circumference of the rotating bracket 1 under its drive, and can also slide along the length of the guide arm 12 to achieve rapid adjustment of the position of the guide arm 12.
[0035] The adjustable arm splitting device has a rotating bracket 1 that can rotate on the mounting body, and a guide arm 12 is provided on the rotating bracket 1. The splitting body 2 is set on the guide arm 12. The splitting body 2 can rotate around the rotating bracket 1 under its circumference and can slide along the length direction of the guide arm 12 to adjust the position of the splitting body 2. It can quickly complete the splitting work of rocks with complex shapes or rocks with different orientations, and improve the splitting efficiency.
[0036] In practical use, workers can use a robotic arm or needle beam to send the splitting body 2 into the tunnel face. Then, by rotating the rotating bracket 1, the splitting body 2 can rotate around the robotic arm or needle beam, thereby changing its circumferential position in the tunnel. The radial position of the splitting body 2 in the tunnel can also be adjusted by sliding the splitting body 2 (sliding along the length of the guide arm 12) to a suitable position for splitting work, thereby improving splitting efficiency.
[0037] Preferably, the inner sidewall of the rotating bracket 1 is provided with a toothed ring and an annular sliding groove. Both the toothed ring and the sliding groove are coaxial with the rotating bracket 1. A sliding rail and a drive motor are provided on the mounting body. The sliding groove and the sliding rail are slidably engaged. The actuating end of the drive motor is provided with a drive gear, which meshes with the toothed ring.
[0038] The operator only needs to control the drive motor to rotate the rotating bracket 1, making the operation of the adjustable arm splitting device more convenient.
[0039] In some embodiments, the guide arm 12 described above is provided with two slide rails 121, the length direction of the slide rails 121 being parallel to the length direction of the guide arm 12, see [reference]. Figure 4 The splitting body 2 is slidably mounted on two slide rails 121 so that the splitting body 2 slides more smoothly and steadily on the guide arm 12.
[0040] In some embodiments, a displacement cylinder 122 is provided on the guide arm 12, and the extension and retraction direction of the displacement cylinder 122 is parallel to the length direction of the guide arm 12. See [reference needed]. Figure 4 The actuating end of the displacement cylinder 122 is connected to the splitting body 2;
[0041] By controlling the extension and retraction of the displacement cylinder 122, the splitting body 2 can slide on the guide arm 12, thereby adjusting the radial position of the splitting body 2 in the tunnel. Preferably, the displacement cylinder 122 is located between two slide rails 121 to prevent the splitting body 2 from shifting during movement, that is, to prevent the length direction of the splitting body 2 from forming an angle with the axis of the rotating support 1, which could cause the splitting body 2 to jam or its working end to be unable to insert into the blast hole for normal splitting work, thus making the use of the adjustable arm splitting device more convenient.
[0042] In some embodiments, the splitting body 2 described above includes a sliding seat 21 and a splitting portion 22, see [link to previous description]. Figure 1 and Figure 2 ;in,
[0043] The two ends of the sliding seat 21 are respectively set on the two slide rails 121, the splitting part 22 is set on the sliding seat 21, and the actuating end of the displacement cylinder 122 is connected to the sliding seat 21.
[0044] The aforementioned splitting section 22 is a splitting arm, which is a commonly used splitting device in the prior art.
[0045] In some embodiments, the sliding seat 21 is provided with a telescopic mechanism, the direction of movement of the telescopic mechanism is parallel to the axis of the rotating support 1, and the splitting part 22 is provided at the moving end of the telescopic mechanism. The telescopic mechanism can drive the splitting part 22 toward or away from the working face to better achieve the rock splitting work.
[0046] Specifically, when there is a certain gap between the rotating support 1 and the working face, and the working end of the splitting part 22 cannot be inserted into the blast hole, the operator can control the telescopic mechanism to push the splitting part 22 towards the working face, thereby reducing the gap between the splitting part 22 and the working face until the working end of the splitting part 22 can be inserted into the blast hole.
[0047] After the splitting work is completed, the telescopic mechanism can be controlled to pull the splitting part 22 away from the working face, so that the splitting part 22 retracts onto the rotating support 1.
[0048] If the telescopic mechanism cannot insert the working end of the splitting part 22 into the blast hole even when it is extended to its limit, the operator can only move the rotating bracket 1 towards the face of the working hole by installing the main body so that the working end of the splitting part 22 can be inserted into the blast hole for splitting work.
[0049] In some embodiments, the circumferential outer wall of the rotating bracket 1 is provided with a mounting surface 11 to facilitate the installation of the guide arm 12, so as to make the installation of the guide arm 12 more convenient.
[0050] In some embodiments, there are multiple guide arms 12, which are arranged circumferentially around the rotating bracket 1 at equal intervals. Each guide arm 12 is provided with a splitting body 2, and the multiple splitting bodies 2 can work together to split the target, thereby improving the working efficiency of the adjustable arm splitting device.
[0051] Preferably, the fixed end of the guide arm 12 is hinged to the mounting plane 11 via a hinge shaft 13, see [reference]. Figure 1 and Figure 2 The axis of the hinge shaft 13 is parallel to the axis of the rotating bracket 1;
[0052] The rotating bracket 1 is provided with an angle adjustment part 14 that can extend and retract. The angle adjustment part 14 is located on one side of the guide arm 12. The extension end of the angle adjustment part 14 is hinged to the movable end of the guide arm 12. By controlling the extension and retraction of the angle adjustment part 14, the guide arm 12 can swing around the axis of the hinge shaft 13.
[0053] If the distance between two adjacent boreholes is less than or greater than the distance between two guide arms 12, the operator can adjust the position of the two adjacent guide arms 12 by controlling the extension and retraction of the angle adjustment unit 14, so that the splitting body 2 on the two adjacent guide arms 12 can be inserted into the two adjacent boreholes at the same time to carry out splitting work, thereby further improving the working efficiency of the adjustable arm splitting device.
[0054] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
