[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0023] Please see Figures 1 to 5 This utility model provides a repair device for anchor cable steel strand sleeves, which includes an air guide pipe 1, a sleeve pipe 2, and a grinding cylinder 3.
[0024] In the embodiments of this utility model, please refer to Figures 1 to 5 The air guide pipe 1 is fitted with a rotatably connected sleeve pipe 2, and the end of the sleeve pipe 2 is fixedly installed with a coaxially arranged and interconnected grinding cylinder 3. The outer wall of the air guide pipe 1 is fixedly fitted with a plurality of equidistantly distributed rotating rings 12. The rotating rings 12 are rotatably connected to the annular grooves opened on the inner wall of the sleeve pipe 2 and / or the grinding cylinder 3. A handle 11 is fixedly installed at one end of the air guide pipe 1 that extends out of the sleeve pipe 2.
[0025] The grinding cylinder 3 is fitted with sandpaper 4 rolled into a cylindrical structure. An insertion ring 31 is fixedly fitted to one end of the grinding cylinder 3 near the sleeve 2. An insertion ring groove 31a is opened at the root of the connection between the insertion ring 31 and the grinding cylinder 3. The other end of the grinding cylinder 3 is fitted with a threaded engagement cap 32. Specifically, an external threaded interface 33 is opened on the head of the grinding cylinder 3. An internal threaded interface 321 for threaded connection of the external threaded interface 33 is provided at the connecting end of the engagement cap 32. An annular pressing edge 322 is fixedly fitted at the threaded connecting end of the engagement cap 32. An annular gap structure is left between the pressing edge 322 and the outer wall of the grinding cylinder 3. One end of the sandpaper 4 rolled into a cylindrical structure is inserted into the insertion ring groove 31a opened in the insertion ring 31. The other end of the sandpaper 4 is inserted into the annular gap structure between the pressing edge 322 and the outer wall of the grinding cylinder 3.
[0026] Furthermore, a number of annularly distributed drive rods 21 are fixedly fitted onto the pipe section of the sleeve 2 near the handle 11, and the drive rods 21 are arranged radially along the sleeve 2.
[0027] It should be noted that: one end of the cylindrical sandpaper 4 is inserted into the insertion annular groove 31a, and then the abutment cap 32 is fitted onto the external threaded interface 33 and threaded connection is made. As the abutment cap 32 is screwed into the external threaded interface 33, the pressing edge 322 presses against the other end of the cylindrical sandpaper 4, thereby realizing the installation of the cylindrical sandpaper 4 on the grinding cylinder 3. When replacing it later, the abutment cap 32 needs to be unscrewed and the sandpaper 4 needs to be slid out before replacing it with a new cylindrical sandpaper 4.
[0028] Subsequently, the staff used the handle 11 to lightly polish the surface of the sleeve damage area by moving the polishing cylinder 3, which was fitted with sandpaper 4, back and forth to increase the surface roughness. At the same time, the staff could also use their thumb and forefinger to drive the drive rod 21, thus causing the polishing cylinder 3 at the end of the sleeve 2 to rotate. Therefore, when needed, the polishing cylinder 3 could be driven to rotate and polish the surface of the sleeve damage area, so that the polishing cylinder 3 could be driven to rotate and polish the sleeve damage area. This made it convenient to polish the sleeve damage areas of various shapes and sizes. Whether it is a round, square or other special-shaped sleeve, a suitable polishing method can be found. It has strong versatility and flexibility. Since the polishing cylinder 3 is driven manually, it will not cause the sleeve damage due to excessive polishing of the tube damage area. In addition, the sleeve repair structure designed in this application has a certain length, so that the debris that falls off the sleeve after polishing is not likely to fall into the hands of the staff.
[0029] In this embodiment, the sandpaper 4 rolled into a cylindrical structure can be cut from a normal-sized sandpaper 4 into a shape with the same length and circumference as the sanding cylinder 3, and then rolled up. The rolled-up connection can be bonded with adhesive.
[0030] In the embodiments of this utility model, please refer to Figure 1 , Figure 3 and Figure 5 A fan 5 is mounted inside the handle 11 via a frame, and a conical air nozzle 32a is provided at the end of the abutment cap 32 away from the internal thread interface 321.
[0031] It should be noted that after the sleeve is polished, turn on the blower 5 and drive the conical air nozzle 32a toward the polished area of the sleeve. This will quickly clean the debris attached to the polished area of the sleeve, so that the workers can use watertight tape to repair the sleeve later. Specifically, align one end of the cut watertight tape with the damaged end, ensuring that the tape adheres tightly to the surface of the sleeve. Then, slowly start to stick the tape to the other end, pressing the tape with your hand or a tool (such as a scraper) while sticking it to ensure that it makes full contact with the surface of the sleeve and removes the air between the tape and the sleeve.
[0032] The working principle of the anchor cable steel strand sleeve repair device provided by this utility model is as follows:
[0033] One end of the cylindrical sandpaper 4 is inserted into the insertion annular groove 31a. Then, the abutment cap 32 is fitted onto the external threaded interface 33 and threaded connection is made. As the abutment cap 32 is screwed into the external threaded interface 33, the pressing edge 322 presses against the other end of the cylindrical sandpaper 4, thereby realizing the installation of the cylindrical sandpaper 4 on the grinding cylinder 3. When replacing it later, the abutment cap 32 needs to be unscrewed and the sandpaper 4 needs to be slid out before replacing it with a new cylindrical sandpaper 4.
[0034] Subsequently, the staff uses the handle 11 to lightly grind the surface of the sleeve damage area by moving the grinding cylinder 3, which is fitted with sandpaper 4, back and forth to increase the surface roughness. At the same time, the staff can also use their thumb and forefinger to drive the drive rod 21, thus rotating the grinding cylinder 3 at the end of the sleeve 2. This allows for convenient grinding of sleeve damage areas of various shapes and sizes. Whether the sleeve is round, square, or has other special shapes, a suitable grinding method can be found, which has strong versatility and flexibility. Therefore, when needed, the grinding cylinder 3 can be driven to rotate so that the sandpaper 4 can rotate and grind along the surface of the sleeve damage area. Since the grinding cylinder 3 is driven manually, there is no risk of the sleeve being damaged due to excessive grinding. In addition, the sleeve repair structure designed in this application has a certain length, so that the debris that falls off the sleeve after grinding is not likely to fall into the staff's hands.
[0035] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
