[0002] In the field of mining engineering, anchor bolting is a crucial technical means of ensuring tunnel stability and safety, and is widely used in various mining operations. By penetrating deep into the rock mass and forming an integral part with the surrounding rock, anchor bolts effectively control deformation and prevent collapse. During anchor bolt installation, precise positioning and reliable clamping are key elements in ensuring effective anchor bolting.

[0003] Some devices use mechanical clamps or bolts for fastening, which are cumbersome to operate and require workers to use multiple tools for repeated debugging, consuming a lot of time and manpower. Moreover, such devices have poor versatility and are difficult to adapt to anchor rods of different diameters and specifications. When faced with diverse mining operation needs, different clamping components often need to be frequently replaced, seriously affecting the construction progress. Therefore, a mining anchor rod installation device is proposed. Utility Model Content

[0026] 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.

[0027] Reference Figure 1-Figure 3 The utility model provides an embodiment of a mining anchor installation device, including a base plate 1, a support plate 2 is fixedly connected to the outer wall of the rear side of the base plate 1, and the support plate 2 plays the role of supporting and fixing the motor 3 so that the motor 3 can run stably. The top of the support plate 2 is fixedly connected to the motor 3. The motor 3 serves as the power source of the entire device, outputs rotational power through the output end, drives the screw rod 4 to rotate, thereby realizing the movement of other components in the device, and the output end of the motor 3 is fixedly connected to the screw rod 4. The outer wall of the screw rod 4 is threadedly connected to a threaded block 5. When the screw rod 4 rotates, due to the cooperation of the thread, the threaded block 5 can perform linear motion along the axial direction of the screw rod 4, converting the rotational motion of the screw rod 4 into linear motion. The outer wall of the threaded block 5 is fixedly connected to a mounting plate 6, and a fastening assembly is fixedly connected to the side of the mounting plate 6 away from the threaded block 5. The linear movement of the threaded block 5 drives the mounting plate 6 to move synchronously. The mounting plate 6 is used to install the fastening assembly, so that the fastening assembly can be adjusted along with the mounting plate 6 to adapt to different anchor installation requirements. A positioning hole 16 is opened in the middle of the base plate 1. The positioning hole 16 is used to locate the installation position of the mining anchor so that the anchor can be accurately installed in the predetermined position. A limit assembly is provided on the surface of the base plate 1. The limit assembly is used to limit the position of the mining anchor during the installation process to prevent the anchor from deflecting during the installation process, thereby further ensuring the accuracy and stability of the installation.

[0028] Reference Figure 1-Figure 3The fastening assembly includes a mounting tube 7, which is fixedly connected to the outer wall of the mounting plate 6. The mounting tube 7 serves as the main part of the fastening assembly and provides installation space and support for other components. The outer wall of the mounting tube 7 is threadedly connected with a rotating cover 8. By rotating the rotating cover 8, the rotating cover 8 can be screwed in or out on the mounting tube 7, thereby adjusting the size of the internal space of the fastening assembly to accommodate anchor rods of different sizes. A circular ring 9 is fixedly connected to the inner wall of the rotating cover 8. The circular ring 9 plays a role in positioning and guiding the clamping block 10, so that the clamping block 10 can move and work stably in the circular ring 9. The inner wall of the circular ring 9 is clamped with a clamping block 10, which is used to directly clamp the anchor rod. When the rotating cover 8 is rotated, the clamping block 10 will be squeezed or relaxed, thereby achieving clamping or loosening of the anchor rod to meet the needs of anchor rod installation and disassembly.

[0029] Reference Figure 1-Figure 3 The limiting assembly includes two guide rods 11, which are fixedly connected to the inner wall of the bottom plate 1. The guide rods 11 provide a guide for the sliding of the slide rod 12, so that the slide rod 12 can move linearly along a fixed direction. The outer wall of the guide rod 11 is slidably connected with the slide rod 12. The slide rod 12 can slide freely on the guide rod 11. The sliding of the slide rod 12 drives the connecting plate 13 and the splint 14 to move, thereby realizing the limiting function of the anchor rod. The top of the slide rod 12 is fixedly connected with a connecting plate 13, which is used to connect the slide rod 12 and the splint 14. The movement of the slide rod 12 is transmitted to the splint 14, so that the splint 14 can limit the anchor rod. The two connecting plates 13 are fixedly connected to the splint 14 on the opposite side. The splint 14 is used to clamp and limit the anchor rod. The anchor rod is restricted to a predetermined position through the relative movement of the two splints 14 to prevent the anchor rod from shifting during the installation process. The outer wall of the guide rod 11 is provided with a spring 15. The spring 15 provides a reset force for the slide rod 12 and the splint 14. When the anchor rod is installed, the spring 15 can automatically reset the splint 14 to facilitate the installation of the next anchor rod.

[0030] Reference Figure 1-Figure 3 The diameter of the clamping block 10 decreases from top to bottom, and the diameter of the inner wall of the mounting tube 7 decreases from top to bottom, so that when the rotating cover 8 is rotated, the clamping block 10 will be gradually squeezed during the downward movement in the mounting tube 7, thereby achieving clamping of the anchor rod, and can adapt to anchor rods of different diameters, improving the stability and applicability of the clamping.

[0031] Reference Figure 1-Figure 3 The clamping plate 14 is arc-shaped. The arc-shaped clamping plate 14 can better fit the surface of the anchor rod, increase the contact area with the anchor rod, and thus improve the clamping effect of the anchor rod.

[0032] Reference Figure 1-Figure 3One end of the spring 15 is fixedly connected to the inner wall of the base plate 1, and the other end of the spring 15 is fixedly connected to the outer wall of the slide rod 12, so that the spring 15 can provide an effective reset force for the slide rod 12. When the slide rod 12 moves under the action of external force, the spring 15 can pull the slide rod 12 back to its original position, ensuring the normal operation of the limit assembly.

[0033] Reference Figure 1-Figure 3 The outer wall of the slide rod 12 is slidably connected to the inner wall of the base plate 1. The inner wall of the base plate 1 provides guidance and support for the sliding of the slide rod 12, so that the slide rod 12 can stably perform linear motion in the base plate 1, ensuring the movement accuracy and reliability of the limit assembly.

[0034] Working principle: When the anchor rod needs to be installed, the anchor rod is placed inside the clamping block 10. Then, the rotating cover 8 is rotated and screwed into the outer wall of the installation tube 7. Since the ring 9 on the inner wall of the rotating cover 8 is engaged with the clamping block 10, the screwing of the rotating cover 8 will push the clamping block 10 to move downward in the installation tube 7. Since the diameter of the clamping block 10 decreases from top to bottom, and the diameter of the inner wall of the installation tube 7 also decreases from top to bottom, the clamping block 10 will be gradually squeezed during the downward movement, thereby clamping the anchor rod.

[0035] Subsequently, the motor 3 is started, and the output end of the motor 3 drives the screw rod 4 to rotate. The screw rod 4 cooperates with the thread of the threaded block 5, causing the threaded block 5 to move downward along the axial direction of the screw rod 4, thereby driving the mounting plate 6 and the fastening assembly mounted on the mounting plate 6 to move downward. As the anchor rod moves downward, the anchor rod pushes the clamping plate 14 to move to both sides, and the sliding rod 12 slides on the guide rod 11, compressing the spring 15. As the spring 15 compresses, the elastic force generated by the spring 15 pushes the clamping plate 14 to clamp the anchor rod in place, preventing the anchor rod from deflecting during installation.

[0036] Subsequently, the screw rod 4 drives the fastening assembly and the anchor rod to move downward, and the anchor rod is inserted into the predetermined installation position through the positioning hole 16 .

[0037] 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.
