Description

Technical Field

[0001] This utility model relates to the field of anchor plate technology, specifically to a prestressed anchor plate protective component. Background Technology

[0002] A prestressed anchor bolt consists of an anchor head, a bolt body (or anchor cable), and a bearing plate. It applies a certain prestress to the surrounding rock or structure through the anchoring force generated by the anchor head, actively reinforcing the rock or structure. The anchor plate is a component that disperses the tensile force of the anchor head.

[0003] Currently, when prestressed anchor plates are pre-embedded and fixed, the grooves connecting to the anchor heads are generally covered with tape to prevent debris from falling into the grooves during the pre-embedding process. However, the tape covering is not easy to completely cover the grooves, and debris can still easily adhere to them. As a result, when the anchor head is stuck in the groove, the tension on it cannot be evenly distributed on the plate, and force deviation will occur. Utility Model Content

[0004] The purpose of this utility model is to provide a prestressed anchor plate protective component to solve the above-mentioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prestressed anchor plate protective component, comprising:

[0006] The pad body has an anchor head connection groove at one end and multiple reinforcing blocks integrally connected to one end of the pad body;

[0007] A protective plate is disposed inside the anchor head connecting groove. A number of fixing blocks corresponding to multiple reinforcing blocks are fixed on the outer side of the protective plate. A movable cavity is opened inside the fixing block. A limiting plate is provided inside the movable cavity. The outer end of the limiting plate slides in contact with the inner wall of the movable cavity. A limiting rod is fixed on the outer side of the limiting plate. A limiting groove is opened at the end of the reinforcing block near the fixing block. One end of the limiting rod passes through one end of the fixing block and extends into the limiting groove. A return spring is fixed between the inner side of the limiting plate and one end inside the movable cavity.

[0008] Preferably, the diameter of the protective plate is the same as the diameter of the anchor head, which facilitates comprehensive protection of the inside of the connecting groove.

[0009] Preferably, the end of the fixing block away from the protective plate has a connecting hole to facilitate the passage of the pull rope.

[0010] Preferably, a pull rope is fixedly connected to the inner side of the limiting plate. One end of the pull rope passes through the reset spring and the inside of the connecting hole and extends to one end of the fixed block, which facilitates the movement of the limiting plate and the limiting rod.

[0011] Preferably, a winding rod is rotatably connected to the middle of the outer side of the protective plate, and one end of each of the multiple pull ropes is fixedly connected to the outer end of the winding rod, which facilitates the winding of multiple pull ropes.

[0012] Preferably, a rotating groove is provided in the middle of the outer side of the protective plate, and a rotating plate is rotatably connected inside the rotating groove. One end of the winding rod passes through the middle of the outer side of the protective plate and is fixedly connected to the rotating plate, so as to facilitate the rotation of the winding rod.

[0013] Preferably, a rotating block is fixedly provided at the other end of the winding rod, and the outer end of the rotating block is provided with multiple anti-slip grooves to facilitate the rotation of the winding rod.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] By using multiple limiting rods to limit and fix the protective plate inside the anchor head connection groove, the inside of the anchor head connection groove can be effectively protected. This effectively avoids the situation where foreign matter sticks to the inside of the anchor head connection groove during the pre-embedding process of the pad body. As a result, the anchor head can be accurately locked inside the anchor head connection groove, and the tension on the anchor head can be evenly distributed on the pad body, avoiding force deviation. Moreover, the protective plate and the structure on it can be reused, which saves resources. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figures 1 to 5 The prestressed anchor plate protective component shown includes:

[0026] The pad body 1 has an anchor head connection groove 2 at one end and multiple reinforcing blocks 3 integrally connected to one end of the pad body 1.

[0027] The protective plate 4 is located inside the anchor head connecting groove 2. The diameter of the protective plate 4 is the same as that of the anchor head. A number of fixing blocks 5 corresponding to multiple reinforcing blocks 3 are fixed on the outside of the protective plate 4. A movable cavity 6 is opened inside the fixing block 5. A limiting plate 7 is provided inside the movable cavity 6. The outer end of the limiting plate 7 slides in contact with the inner wall of the movable cavity 6. A limiting rod 8 is fixed on the outside of the limiting plate 7. A limiting groove 9 is opened at one end of the reinforcing block 3 near the fixing block 5. One end of the limiting rod 8 passes through one end of the fixing block 5 and extends into the limiting groove 9. A return spring 10 is fixed between the inner side of the limiting plate 7 and one end inside the movable cavity 6.

[0028] A connecting hole 11 is provided at the end of the fixing block 5 away from the protective plate 4. A pull rope 12 is fixedly connected to the inner side of the limiting plate 7. One end of the pull rope 12 passes through the reset spring 10 and the interior of the connecting hole 11 and extends to one end of the fixing block 5. A winding rod 13 is rotatably connected to the middle of the outer side of the protective plate 4. One end of multiple pull ropes 12 is fixedly connected to the outer end of the winding rod 13. A rotating groove 14 is provided in the middle of the outer side of the protective plate 4. A rotating plate 15 is rotatably connected inside the rotating groove 14. One end of the winding rod 13 passes through the middle of the outer side of the protective plate 4 and is fixedly connected to the rotating plate 15. A rotating block 16 is fixedly provided at the other end of the winding rod 13. Multiple anti-slip textures are provided on the outer end of the rotating block 16.

[0029] When pre-embedding the pad body 1, rotate the rotating block 16. The rotating block 16 drives the winding rod 13 to rotate, and the winding rod 13 drives the rotating plate 15 to rotate inside the rotating groove 14. The winding rod 13 will simultaneously wind up multiple pull ropes 12. The pull ropes 12 drive the limiting plate 7 to move inward. The limiting plate 7 drives the limiting rod 8 to move into the movable cavity 6 and simultaneously compresses the reset spring 10. When one end of the limiting rod 8 enters the movable cavity 6, the protective plate 4 is inserted into the anchor head connecting groove 2, so that one end of the limiting rod 8 is located inside the limiting groove 9 on the reinforcing block 3. Then, release the rotating block 16, and the limiting plate 7 will... Under the elastic force of the return spring 10, one end of the limiting rod 8 is inserted into the limiting groove 9. In this way, the limiting rod 8 will limit and fix the protective plate 4 inside the anchor head connecting groove 2. The protective plate 4 will protect the inside of the anchor head connecting groove 2. After the pad body 1 is pre-embedded, rotate the rotating block 16 and the winding rod 13. At this time, one end of the limiting rod 8 will leave the inside of the limiting groove 9 under the pulling force of the limiting plate 7 and the pull rope 12. In this way, the protective plate 4 can be taken out from the inside of the anchor head connecting groove 2. Then the anchor head can be stuck inside the anchor head connecting groove 2. This can prevent debris stuck inside the anchor head connecting groove 2 from affecting the accurate insertion of the anchor head.

[0030] This utility model uses multiple limiting rods 8 to limit and fix the protective plate 4 inside the anchor head connecting groove 2, which can effectively protect the inside of the anchor head connecting groove 2 and effectively prevent the occurrence of foreign matter adhering inside the anchor head connecting groove 2 during the pre-embedding process of the pad body 1. This allows the anchor head to be accurately locked inside the anchor head connecting groove 2, and the tension on the anchor head can be evenly distributed on the pad body 1, avoiding force deviation. Moreover, the protective plate 4 and its structure can be reused, which saves resources. This embodiment specifically solves the problem in the prior art that when the prestressed anchor pad is pre-embedded and fixed, the groove connecting to the anchor head generally needs to be covered with tape to prevent foreign matter from falling into the groove during the pre-embedding process. However, the tape covering is not easy to completely cover the groove, and foreign matter can still easily adhere to the groove. Therefore, when the anchor head is locked inside the groove, the tension on it cannot be evenly distributed on the pad, resulting in force deviation.

[0031] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
