Description

Technical Field

[0001] This utility model relates to the field of open-pit mine slope treatment, specifically an anchor cable structure for open-pit mine slope treatment. Background Technology

[0002] An open-pit mine is a type of mine that extracts minerals from the ground up. This method is mainly suitable for situations where the ore body is shallow or exposed. Open-pit mines are characterized by high production efficiency and low cost, and are widely used globally for mining various mineral resources such as iron ore, copper ore, and coal.

[0003] During the mining process in open-pit mines, slope stabilization anchor cable structures are often installed to treat the slopes. However, during the installation of these anchor cable structures, the grouting solution in the grouting holes is often blocked by gravel from the slope, preventing the grouting holes from being completely filled and thus affecting the construction of the anchor cable structure. Utility Model Content

[0004] The purpose of this utility model is to provide an anchor cable structure for slope treatment in open-pit mines, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An anchor cable structure for slope stabilization in open-pit mines includes a tensioning plate. The outer end of the tensioning plate has several equally spaced insertion holes into which anchor cable bodies are inserted. A second reinforcing rod is located at the center of the tensioning plate, between the anchor cable bodies. Several clamping components for clamping each anchor cable body are equally spaced on the second reinforcing rod. A mounting base is located at the end of the second reinforcing rod. A connecting hole is located inside the second reinforcing rod, and a through hole is provided between the connecting hole and the mounting base. Several connecting recesses are equally spaced on the outer end of the second reinforcing rod. Several through cavities are equally spaced on the second reinforcing rod inside the connecting recesses. An outlet hole connected to the connecting recess is located at the outer end of each through cavity, and an inlet hole connected to the connecting hole is located at the inner end of each through cavity. An arc-shaped sealing block for sealing the inlet hole is located at the bottom of the through cavity, and the outer end of the arc-shaped sealing block is elastically connected to the inner wall of the through cavity via a return spring.

[0007] Preferably, a fixing nut for fixing the end of the anchor cable body is installed on the anchor cable body located on one side of the tensioning plate.

[0008] Preferably, the clamping assembly includes a fixing block fixedly mounted on the second reinforcing rod, and a plurality of first reinforcing rods are evenly spaced at the outer end of the fixing block. A connecting sleeve is provided at the outer end of the first reinforcing rod, and the connecting sleeve is provided on the outside of each anchor cable body.

[0009] Preferably, the outer wall of the connecting sleeve is provided with a threaded hole, and a brake bolt is provided inside the threaded hole.

[0010] Preferably, the inner wall and outer wall of the mounting base are respectively provided with an internal thread and an external thread.

[0011] Preferably, a connecting rod is provided at the center of the outer end of the arc-shaped sealing block, and a sealing plug is provided at the outer end of the connecting rod, with the sealing plug located at the outer opening of the liquid outlet.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model allows the grouting solution to enter the connecting hole through the guide hole via the mounting base. The grouting solution squeezes the arc-shaped sealing block to move outward, and the return spring compresses to generate elastic force. The grouting solution is then added into the mounting hole through the guide cavity and the outlet hole, thereby achieving grouting treatment of the mounting hole for the anchor cable structure. This facilitates the fixed connection between the anchor cable structure and the open-pit mine slope, thus facilitating the treatment of the open-pit mine slope. Moreover, the arc-shaped sealing block can seal the inlet hole, preventing gravel from the slope from falling into the inlet hole and blocking the grouting hole. This allows for complete grouting treatment of the mounting hole, facilitating the safe treatment of the open-pit mine slope. Attached Figure Description

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of this utility model to enable the reader to better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and with various changes and modifications based on the following embodiments.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] See Figure 1-4 In this embodiment of the utility model, an anchor cable structure for slope treatment in an open-pit mine includes a tensioning pad 1. The tensioning pad 1 has several equally spaced insertion holes 2 at its outer end, into which anchor cable bodies 3 are inserted. A second reinforcing rod 10 is located at the center of the tensioning pad 1, between the anchor cable bodies 3. Several clamping components for clamping each anchor cable body 3 are equally spaced on the second reinforcing rod 10. A mounting base 12 is located at the end of the second reinforcing rod 10. A connecting hole 11 is formed inside the second reinforcing rod 10, and a connection is provided between the connecting hole 11 and the mounting base 12. The second reinforcing rod 10 has a number of connecting recesses 16 at equal intervals on its outer end. The second reinforcing rod 10 located inside the connecting recesses 16 has a number of connecting cavities 17 at equal intervals. The outer end of the connecting cavity 17 is provided with an outlet hole 18 that is connected to the connecting recesses 16. The inner end of the connecting cavity 17 is provided with an inlet hole 19 that is connected to the connecting hole 11. The bottom of the inner part of the connecting cavity 17 is provided with an arc-shaped sealing block 20 for sealing the inlet hole 19. The outer end of the arc-shaped sealing block 20 is elastically connected to the inner wall of the connecting cavity 17 through a return spring 23.

[0022] The anchor cable body 3 is installed by inserting it into the various insertion holes 2 on the tensioning plate 1. The anchor cable body 3 is clamped in multiple places by the clamping assembly. After clamping, the anchor cable structure is installed in the installation hole opened for the treatment of the open-pit mine slope. The grouting solution is introduced into the connection hole 11 through the guide hole 13 through the mounting seat 12. The grouting solution squeezes the arc-shaped sealing block 20 to move outward. The return spring 23 is compressed to generate elastic force. The grouting solution is added into the installation hole through the guide cavity 17 and the liquid outlet 18, thereby realizing the grouting treatment of the installation hole for the anchor cable structure. This makes it convenient to fix the anchor cable structure to the open-pit mine slope, thus facilitating the treatment of the open-pit mine slope.

[0023] See Figure 1 In one embodiment of this utility model, a fixing nut 4 for fixing the end of the anchor cable body 3 is installed on the anchor cable body 3 located on one side of the tensioning pad 1. The fixing nut 4 can facilitate the braking of the anchor cable body 3, thereby facilitating the installation between the anchor cable body 3 and the tensioning pad 1.

[0024] See Figure 1 In one embodiment of this utility model, the clamping assembly includes a fixing block 5 fixedly installed on the second reinforcing rod 10. A plurality of first reinforcing rods 6 are evenly spaced on the outer end of the fixing block 5. A connecting sleeve 7 is provided on the outer end of the first reinforcing rod 6. The connecting sleeve 7 is located on the outside of each anchor cable body 3. By installing a plurality of fixing blocks 5 on the second reinforcing rod 10, the fixing blocks 5 clamp the anchor cable bodies 3 through the first reinforcing rods 6 and the connecting sleeve 7. This facilitates the limiting treatment of each anchor cable body 3, effectively preventing the installed anchor cable bodies 3 from spreading out. This allows the anchor cable structure to be easily inserted into the installation hole opened in the slope, thus facilitating the use of the anchor cable structure.

[0025] See Figure 1 In one embodiment of this utility model, a threaded hole 8 is provided on the outer wall of the connecting sleeve 7, and a brake bolt 9 is provided inside the threaded hole 8. By manually rotating the brake bolt 9, it moves inward inside the threaded hole 8 and contacts the surface of the anchor cable body 3, so as to achieve a stable connection between the connecting sleeve 7 and the anchor cable body 3, thereby facilitating the use of the equipment.

[0026] See Figure 1 In one embodiment of this utility model, an internal thread 14 and an external thread 15 are respectively provided on the inner and outer walls of the mounting base 12. The provision of the internal thread 14 and the external thread 15 can facilitate the threaded sealing connection between the mounting base 12 and the grouting pipe.

[0027] See Figure 1 In one embodiment of this utility model, a connecting rod 21 is provided at the center of the outer end of the arc-shaped sealing block 20, and a sealing plug 22 is provided at the outer end of the connecting rod 21. The sealing plug 22 is provided at the outer opening of the liquid outlet hole 18. The sealing plug 22 can block the liquid outlet hole 18, thus preventing the crushed stone from the open-pit mine from falling into the liquid outlet hole 18 and causing the equipment to be unable to perform grouting.

[0028] Working principle: This utility model involves sequentially inserting the anchor cable body 3 into each insertion hole 2, braking the anchor cable body 3 with a fixing nut 4, fixing the fixing block 5 onto the second reinforcing rod 10, inserting each anchor cable body 3 into each connecting sleeve 7, and manually rotating the braking bolt 9 to connect with the threaded hole 8. The inner end of the braking bolt 9 contacts the surface of the anchor cable body 3, thereby achieving stable installation between the connecting sleeve 7 and the anchor cable body 3. The anchor cable structure is then inserted into the installation hole opened for open-pit mine slope treatment. The tensioning plate 1 seals the outer end of the mounting hole. The grouting pipe is threaded to the internal thread 14 and external thread 15 on the mounting base 12. The grouting pipe delivers the grouting solution into the connecting hole 11 through the guide hole 13. The grouting solution inside the connecting hole 11 enters the inlet hole 19. The grouting solution squeezes the arc-shaped sealing block 20 to move outward. The grouting solution is then injected into the space inside the mounting hole through the guide cavity 17 and the outlet hole 18. This allows the anchor cable structure to be used for the treatment of open-pit mine slopes.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
