Technical Field

[0001] This utility model relates to the field of wrench technology, and in particular to a quick-connect wrench for prestressed pipe piles. Background Technology

[0002] In the construction of prestressed concrete pipe piles, the connection of the piles is a crucial step. Traditional connection methods typically involve tightening the connecting bolts using ordinary wrenches or simple tools, which has several drawbacks. Firstly, ordinary wrenches come in specific models, each suitable only for one type of bolt, causing inconvenience and hindering rapid bolt assembly on the construction site. Secondly, traditional wrenches are inefficient, requiring significant time and manpower in large-scale pipe pile construction projects, severely slowing down the construction progress. Furthermore, the complex environment of construction sites further complicates matters, making ordinary wrenches less versatile and inconvenient to operate, further reducing construction efficiency. Therefore, it is necessary to develop a wrench for prestressed concrete pipe piles that allows for quick, accurate, and convenient connection. Summary of the Invention

[0030] Example 1

[0031] like Figure 1-3 As shown, the quick connection wrench for prestressed pipe piles proposed in this utility model includes a wrench body 1. The wrench body 1 includes a handle part 11 and a fixed wrench end 12 and a plum blossom open end 13 located at both ends of the handle part 11. A built-in spline assembly 2 is detachably installed in the plum blossom open end 13. A limiting assembly 3 for connecting the two is provided between the built-in spline assembly 2 and the plum blossom open end 13.

[0032] Reference Figure 2As shown, the inner wall of the plum blossom opening end 13 has a connecting groove 130, the built-in spline assembly 2 includes an outer ring 21, the inner wall of the outer ring 21 is fixedly connected to an annular spline 22, and the outer wall of the outer ring 21 is connected to a connecting block 23 that is adapted to and installed in the connecting groove 130.

[0033] The limiting component 3 includes a mounting rod 33 that passes through the connecting groove 130. A mounting hole 230 corresponding to the diameter of the mounting rod 33 is opened on a connecting block 23. The cross-section of the connecting block 23 and the connecting groove 130 is a "T" shaped structure. The connecting block 23 and the connecting groove 130 are used to quickly detach and assemble the built-in spline component 2 and the inner wall of the plum blossom opening end 13. A sliding groove 131 located at the bottom of the plum blossom opening end 13 is opened on one side of the connecting groove 130. A through hole is opened between the sliding groove 131 and the connecting groove 130. The mounting rod 33 passes through the inner wall of the through hole and slides relative to the through hole. A sliding block 32 is fixedly connected to one end of the mounting rod 33 located in the sliding groove 131. A toggle block is fixedly connected to the bottom of the sliding block 32. A spring 31 is fixedly connected to one side of the sliding block 32. The other end of the spring 31 is fixedly connected to the inner wall of one side of the sliding groove 131.

[0034] In this embodiment, when installing prestressed pipe piles at the construction site, if different types of bolts need to be disassembled or installed, and if different types require the use of annular splines 22 with different inner diameters, the actuating block is pushed, causing the spring 31 to compress and the synchronous sliding block 32 to move, so that one end of the mounting rod 33 is disengaged from the mounting hole 230. The thumb can be inserted into the annular spline 22 and pulled out from the open end 13. When installing the annular spline 22, the connecting block 23 is pressed down on the two corresponding connecting grooves 130, and one actuating block is released at the same time, so that the spring 31 rebounds, and the connecting groove 130 slides along the inner wall of the through hole and locks into the mounting hole 230, thus realizing the installation of the annular spline 22.

[0035] Example 2

[0036] like Figure 1 and Figure 2 As shown, based on Embodiment 1, raised anti-slip parts 15 are provided on both sides of the handle part 11, and a hook plate 14 is fixedly connected to one side of the handle part 11.

[0037] In this embodiment, the hook plate 14 is used to hang the entire wrench body 1 for storage, making it convenient and quick to retrieve the wrench for use without having to search in the toolbox. The raised anti-slip part 15 is also provided to ensure a non-slip grip, further improving the safety of wrench use.

[0038] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
