It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0031] Please refer to Figures 1 to 6 , the present invention provides a technical solution: a portable anchor cable hole forming and grouting device, including: a fixed plate 1, round holes 3 are opened at the upper ends of the fixed plate 1, the round holes 3 are detachably installed with a fixed cylinder 7 through a connecting component, a sharp cone 8 is fixedly installed at the lower end of the fixed cylinder 7, and the sharp cone 8 is provided to facilitate driving the fixed cylinder 7 into the ground. The connecting component includes a limit hole 4, a ring 9 and a fastening nut 15. There are several limit holes 4, which are evenly opened on the inner wall of the round hole 3. The ring 9 is sleeved on the outer side of the upper end of the fixed cylinder 7 and fixedly connected to the outer wall of the fixed cylinder 7. Several limit blocks 10 are evenly and fixedly installed at the upper end of the fixed cylinder 7. An external thread one 11 is opened at the upper end of the fixed cylinder 7. The diameter of the ring 9 is larger than the diameter of the round hole 3.

[0032] Pass the upper end of the fixed cylinder 7 through the round hole 3 from below the fixed plate 1, make the ring 9 contact the lower end side wall of the fixed plate 1, and at the same time insert the limit block 10 into the limit hole 4. The upper end of the fixed cylinder 7 is threadedly connected to the inner wall of the fastening nut 15 through the external thread one 11. By screwing the fastening nut 15 tightly, the fixed cylinder 7 is fixed. By driving the fixed cylinder 7 into the ground, the fixed plate 1 is fixed on the ground, and at the same time, it is convenient to disassemble and assemble the fixed cylinder 7.

[0033] On the left and right sides of the lower end of the fixed cylinder 7, there are symmetrically provided with upwardly inclined inclined holes 12 and rectangular openings 13. The rectangular opening 13 is located at the lower end of the inclined hole 12. Inside the fixed cylinder 7, there is a threaded rod 16 rotatably connected by a bearing. The upper end of the threaded rod 16 passes through the outer end of the fixed cylinder 7, and the lower end of the threaded rod 16 is fixedly connected to the inner wall of the bearing. The outer wall of the bearing is fixed on the inner wall of the bottom end of the fixed cylinder 7, so that the threaded rod 16 can rotate in place. On the outer wall of the lower end of the threaded rod 16, there are threadedly sleeved with a first thread sleeve 17 and a second thread sleeve 18 from top to bottom. Both the left and right ends of the first thread sleeve 17 are rotatably connected with arc-shaped plates 19. On the outer wall of the arc-shaped plate 19, a number of inclined plates 20 are uniformly fixedly installed. The outer ends of the inclined plates 20 are slidably inserted into the inclined holes 12. The inner end of the arc-shaped plate 19 is fixedly installed with a slide rail 21. Inside the slide rail 21, there is a slider 22 slidably connected. The lower sides of the front and rear ends of the slider 22 are rotatably connected with a first rotating rod 23. The other end of the first rotating rod 23 is threadedly connected to the outer wall of the first thread sleeve 17. By rotating the threaded rod 16, the threaded rod 16 drives the first thread sleeve 17 to move downward. When the first thread sleeve 17 moves downward, it will drive one end of the first rotating rod 23 to move downward synchronously. The first rotating rod 23 drives the slider 22 to slide on the slide rail 21, and at the same time, pushes the arc-shaped plate 19 and the inclined plate 20 outward, so as to drive the outer ends of the inclined plate 20 and the rotating plate 14 to the outside of the fixed cylinder 7, increasing the contact area between the fixed cylinder 7 and the soil, and fixing the fixed cylinder 7 more firmly.

[0034] On the outer walls of the left and right ends of the second thread sleeve 18, there are rotatably connected with rotating plates 14. The rotating plates 14 are located inside the rectangular openings 13. The lower ends of the rotating plates 14 are rotatably connected to the outer wall of the fixed cylinder 7 through hinges. The inner sides of the upper ends of the rotating plates 14 are rotatably connected with second rotating rods 24 through ear plates. The upper ends of the second rotating rods 24 are rotatably connected to the outer walls of the second thread sleeves 18. By rotating the threaded rod 16 to drive the second thread sleeve 18 to move downward, when the second thread sleeve 18 moves downward, it will drive one end of the second rotating rod 24 to move downward. When the second rotating rod 24 moves downward, it will push the upper ends of the rotating plates 14 outward, and the upper ends of the rotating plates 14 are inserted into the soil, increasing the contact area between the fixed cylinder 7 and the soil, and fixing the fixed cylinder 7 more firmly.

[0035] On both the left and right sides of the upper end of the fixing plate 1, threaded cylinders 2 are fixedly installed. The lower end of the threaded cylinder 2 penetrates through the upper and lower ends of the fixing plate 1. The upper end of the threaded cylinder 2 is detachably installed with a drilling cylinder 25. A moving ring 29 is sleeved on the outer end of the threaded cylinder 2. A number of springs 31 are evenly and fixedly installed at the lower end of the moving ring 29. The lower ends of the springs 31 are fixedly installed on the upper end of the fixing plate 1. A number of inserting columns 30 are evenly and fixedly installed at the upper end of the moving ring 29. The upper end of the threaded cylinder 2 is provided with a drilling cylinder 25. External threads two 26 are provided on the outer walls of the upper and lower ends of the drilling cylinder 25. A retaining ring 27 is fixedly installed on the outer wall of the middle end of the drilling cylinder 25. A number of inserting holes 28 corresponding to the inserting columns 30 are evenly provided on the outer wall of the retaining ring 27. The lower end of the drilling cylinder 25 is threadedly connected to the threaded cylinder 2. When the drilling cylinder 25 and the threaded cylinder 2 are threadedly connected, first push down the moving ring 29 by compressing the springs 31. After the drilling cylinder 25 and the threaded cylinder 2 are connected, release the moving ring 29. Under the reaction force of the springs 31, the inserting columns 30 slide and insert into the inserting holes 28 to fix the drilling cylinder 25. Then, the drill rod can be inserted into the drill rod hole, and the remote control is operated to carry out the drilling construction. After the hole is formed, the drill rod is pulled out.

[0036] The upper end of the drilling cylinder 25 is connected with a grouting pipe 33 through a sealing cover 32. The upper end of the drilling cylinder 25 is threadedly connected to the sealing cover 32. And the grouting pipe 33 is fixedly installed at the upper end of the sealing cover 32 and communicated with the inner end of the sealing cover 32. After the drilling is completed, the external slurry conveying pipe is connected to the grouting pipe 33 for grouting.

[0037] A construction method of a lightweight anchor cable hole forming and grouting device specifically includes the following steps:

[0038] First, the fixed cylinder 7 is fixedly installed at the four ends of the fixing plate 1 through the connecting components. Mark the position where drilling is required. Fix the fixing plate 1 on the ground by driving the fixed cylinder 7 into the ground, so that the threaded cylinder 2 is located above the position where drilling is required.

[0039] Then, drive the thread sleeve one 17 and the thread sleeve two 18 to move downward by rotating the threaded rod 16, so as to drive the inclined plate 20 and the rotating plate 14 to the outer end of the fixed cylinder 7. When the thread sleeve one 17 and the thread sleeve two 18 move downward, they will drive the rotating rod one 23 and the rotating rod two 24 to move downward. The rotating rod one 23 drives the slider 22 to slide on the slide rail 21, and at the same time pushes the arc plate 19 and the inclined plate 20 outward. When the rotating rod two 24 moves downward, it pushes the upper end of the rotating plate 14 outward, so as to drive the outer ends of the inclined plate 20 and the rotating plate 14 to the outside of the fixed cylinder 7 and further fix the fixed cylinder 7.

[0040] Next, install the drilling cylinder 25 at the upper end of the threaded cylinder 2. When the drilling cylinder 25 is threadedly connected to the threaded cylinder 2, first push down the moving ring 29 through the compression spring 31. After the drilling cylinder 25 and the threaded cylinder 2 are connected, release the moving ring 29. Under the reaction force of the spring 31, the insertion column 30 slides and inserts into the insertion hole 28 to fix the drilling cylinder 25. Then, insert the drill rod into the drill rod hole, operate the remote control to perform the drilling construction, and pull out the drill rod after the hole is formed.

[0041] Finally, after the anchor cable is processed, insert it into the drill hole. Then, install the sealing cover 32 and the grouting pipe 33 at the upper end of the drilling cylinder 25, and connect the external grouting pipe to the grouting pipe 33 to perform grouting.

[0042] As Figure 1 and Figure 2 shown, in some embodiments, a power sensor 5 is fixedly installed on one side of the upper end of the fixing plate 1, and a pressure sensor 6 is fixedly installed on the other side. More specifically, the first-piece control device fixes the fixing plate 1 on the soil layer. After confirming that it is firmly fixed, insert the drill rod into the drill rod hole, operate the remote control to perform the drilling construction, and pull out the drill rod after the hole is formed. The device is equipped with a power sensor 5, and the drilling power can be adjusted during the hole-forming process. When encountering a harder rock layer, the force can be increased, and a smaller power can be used for general soil layers.

[0043] After the anchor cable is processed and inserted into the drill hole, then insert the grouting pipe 33 into the grouting hole to perform grouting. The grouting pressure can be controlled by a pressure regulator to ensure that the pressure meets the design requirements.

[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
