[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-3The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0021] like Figure 1-3 As shown: This embodiment provides an anchor pushing device, including a base plate 100. The base plate 100 has seven mounting holes 200 corresponding to the locking holes of the anchor. Each mounting hole 200 corresponds to one of the seven locking holes on the anchor. A sleeve 300 is inserted into each mounting hole 200. A threading hole 400 is provided on the axis of the sleeve 300. The threading holes 400 decrease in size sequentially along the direction of the steel strand insertion, and the smallest diameter of the threading hole 400 transitions with the steel strand. This invention enables quick and convenient threading of multiple steel cables by setting sleeves 300 on the base plate 100 corresponding to the locking holes of the anchor. Furthermore, the design of the threading holes 400 decreasing in size sequentially along the direction of the steel strand insertion facilitates smooth insertion of the steel strand and subsequent guiding and positioning operations, greatly improving the efficiency of steel strand threading and tensioning installation, reducing the workload of workers, and increasing construction efficiency.

[0022] According to one embodiment of the present invention, such as Figure 1-3 As shown, a guide post 500 is provided on the outer wall of the jacket 300, and guide holes are provided on both the anchor and the base plate 100. This utility model can guide the installation of the jacket 300 through the guide post 500 on the outer side of the jacket 300, which greatly improves the installation efficiency of the jacket 300 and makes the operation more convenient.

[0023] According to another embodiment of the present invention, such as Figure 1 and Figure 2 As shown, a gripping part 600 is provided at the base of the sleeve 300, which is a handle. Two handles are provided on the outer side of each sleeve 300. A cross-shaped through groove 700 is provided at the head of the sleeve 300. This utility model allows the operator to quickly and efficiently install the sleeve 300 into the base plate 100 by holding the gripping part 600. It also allows for the individual and quick disassembly, repair and replacement of the corresponding faulty sleeve 300, making the operation more convenient.

[0024] The mounting hole 200 is a threaded hole, and the outer wall of the sleeve 300 is provided with an external thread that matches the threaded hole. This utility model can achieve quick assembly of the sleeve 300 and the base plate 100 by screwing the external thread of the sleeve 300 into the threaded hole, which is more portable and convenient.

[0025] According to another embodiment of the present invention, such as Figure 1 and Figure 3 As shown, the outer wall of the head of the jacket 300 has a corrugated constriction structure. This utility model improves the overall structural strength and rigidity of the jacket 300 by increasing the surface area ratio and thickness variation of the material through the design of the corrugated constriction structure, making it more pressure resistant and playing a good role in preventing deformation. This greatly improves the service life of the jacket 300, and also improves the flexibility of the jacket 300, increasing its bending ability and flexibility. This makes it easier to adapt to different geometric shapes and bending requirements during installation and use. It can also compensate for thermal expansion and contraction, and has the advantages of good sealing performance and easy installation and maintenance.

[0026] How to use this utility model:

[0027] First, it needs to be clarified that the propulsion device involved in this utility model is mainly used for guiding the insertion of steel strands into the locking holes of anchors. The propulsion method can be achieved by using a mechanical, hydraulic, pneumatic, or electric telescopic push rod to move the base plate 100, or by manually pushing the base plate 100 so that the front end of the clamp 300 smoothly enters the appropriate depth position at the end of the locking hole. This utility model will describe the usage method in detail using the propulsion device as an example. When installing steel strands, first select the appropriate size clamp 300 according to the size of the anchor's locking hole, and then the operator holds the handle... The operator aligns the guide post 500 on the jacket 300 with the positioning hole on the anchor and the base plate 100, and then screws the jacket 300 so that its threaded connection is in the threaded hole on the base plate 100. Then, the operator holds the base plate 100 and inserts the corrugated constricted part of the head of the jacket 300 into the locking hole a certain distance. Then, the operator can insert the steel strand into the wire hole 400 in the jacket 300 in one go. After the wire is inserted, the operator presses the base plate 100 inward until the wire hole 400 and the steel strand inside are completely inserted into the locking hole of the anchor. This completes the installation of the strand of the anchor propulsion device.

[0028] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
