[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1-Figure 3The utility model provides an embodiment of a rock drilling rig working arm, including a main support arm 1, the top of the main support arm 1 is rotatably connected to the auxiliary support arm 2, the outer wall of the main support arm 1 is rotatably connected to a hydraulic rod 3, the output end of the hydraulic rod 3 is rotatably connected to the bottom of the auxiliary support arm 2, one end of the auxiliary support arm 2 is rotatably connected to a connecting seat 4, the bottom of the auxiliary support arm 2 is rotatably connected to a hydraulic rod 2 5, the output end of the hydraulic rod 2 5 is rotatably connected to the bottom of the connecting seat 4, the outer wall of the connecting seat 4 is fixedly connected to a bracket 6, one side of the bracket 6 is fixedly connected to a motor 7, and the output end of the motor 7 A bidirectional threaded rod 8 is fixedly connected, and a clamping block 9 is threadedly connected to the outer wall of the bidirectional threaded rod 8. A limiting groove 11 is provided inside the clamping block 9. A limiting component is provided inside the connecting seat 4. The limiting component is used to limit the clamping block 9 in the connecting seat 4. A locking groove 12 is provided inside the clamping block 9. A connecting block 10 is provided inside the connecting seat 4. The outer wall of the connecting block 10 is embedded in the locking groove 12. The limiting component includes a limiting block 13. The top of the limiting block 13 is fixedly connected to the inside of the connecting seat 4, and the outer wall of the limiting block 13 is slidably connected to the inside of the limiting groove 11;

[0032] Specifically, when the fixture needs to be replaced in order to use other equipment, the output end of the motor 7 drives the bidirectional threaded rod 8 to rotate. This is the first step of the entire operation. The function of the bidirectional threaded rod 8 is to control the separation of the clamping block 9. Next, the clamping block 9 slides on the outer wall of the limit block 13 through the limit groove 11 to limit the position. This step ensures the safety and stability of the operation and prevents the clamping block 9 from accidentally moving during the replacement process. After completing the limitation, the connecting block 10 is separated from the locking groove 12. This step lays the foundation for realizing equipment replacement. At this time, you only need to take out the connecting block 10 to complete the disassembly of the old equipment. Then, insert the new equipment into the connecting seat 4 through the connecting block 10. This step ensures the accurate position of the new equipment and prepares for subsequent operations. Finally, the output end of the motor 7 is reversed to close the clamping block 9. This step ensures that the connecting block 10 is clamped, thereby achieving the fixation of the new equipment. At this point, the equipment replacement process is completed and the new equipment can be used.

[0033] Reference Figure 4 , one side of the connecting block 10 is fixedly connected to the base plate 14, and the bottom plate 14 is rotatably connected to the clamping arm 18. One side of the bottom plate 14 is fixedly connected to the hydraulic rod 3 15, and the output end of the hydraulic rod 3 15 is fixedly connected to the connecting plate 16. The outer wall of the connecting plate 16 is rotatably connected to the universal shaft 17, and one end of the universal shaft 17 is rotatably connected to the connecting block 2 19. One side of the connecting block 2 19 is rotatably connected to one side of the clamping arm 18. The clamping arms 18 are arranged in a circular array and rotatably connected to the inside of the bottom plate 14. One end of the clamping arm 18 is rotatably connected to the anti-sliding block 20. The outer wall of the clamping block 9 is symmetrically arranged and slidably connected to the inside of the connecting seat 4;

[0034] Specifically, during the stone clamping process, first, the main support arm 1 is fixed on the trolley, which is the basis of the entire clamping device and provides stable support for subsequent operations. The hydraulic rod 1 3 serves as a power source to drive the auxiliary support arm 2 to rotate on the main support arm 1 to achieve a large-scale pitch angle adjustment. This design allows the operator to flexibly adjust the angle of the clamping device according to actual needs to adapt to various complex environments. Next, the output end of the hydraulic rod 2 5 extends to drive the connecting seat 4 to rotate on the auxiliary support arm 2. This step is to fine-tune the pitch angle so that the clamp can be more flexible. In order to more accurately adapt to the shape and size of the stone and improve the stability of the clamping, the rotation of the connecting seat 4 drives the movement of the hydraulic rod 2 5 to further finely adjust the pitch angle of the clamp. Finally, the output end of the hydraulic rod 3 15 drives the connecting plate 16 to extend, and the connecting plate 16 moves through the universal joint 17. The universal joint 17 is connected to the connecting block 2 19, and then drives the clamping arm 18 to close. In this process, the anti-sliding block 20 plays a key role. It can effectively prevent the stone from sliding or falling during the clamping process. During the closing process, the clamping arm 18 tightly grasps the stone to ensure its stability.

[0035] Working principle: When using the working arm of the rock drilling rig, the main support arm 1 is fixed on the trolley when clamping the stone. The output end of the hydraulic rod 1 drives the auxiliary support arm 2 to rotate on the main support arm 1 to adjust the large pitch angle. Then the output end of the hydraulic rod 2 5 extends to drive the connecting seat 4 to rotate on the auxiliary support arm 2, thereby finely adjusting the pitch angle of the clamp. Then the output end of the hydraulic rod 3 15 drives the connecting plate 16 to extend. The connecting plate 16 moves through the universal joint 17. The universal joint 17 drives the clamping arm 18 to close through the connecting block 2 19. The clamping arm 18 is pressed against the anti-sliding block 20. The stone is fixed, and the anti-sliding block 20 can prevent the stone from slipping and falling. When it is necessary to replace the fixture and use other equipment, the output end of the motor 7 drives the bidirectional threaded rod 8 to rotate, and the bidirectional threaded rod 8 drives the clamping block 9 to separate. The clamping block 9 slides on the outer wall of the limit block 13 through the limit groove 11 to limit the position, and then the connecting block 10 is separated from the locking groove 12, and the connecting block 10 is directly taken out, and then the new equipment is inserted into the connecting seat 4 through the connecting block 10, and then the output end of the motor 7 is reversed to close the clamping block 9, and then the connecting block 10 is clamped and fixed.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
