Description

Technical fields:

[0001] This utility model relates to the technical field of pipe pile production equipment, specifically to a pipe pile prestressing tensioning anti-slip device. Background technology:

[0002] In the production of concrete pipe piles, prestressing tensioning is a crucial process that determines the structural strength and bearing capacity of the pipe pile. It requires applying a pre-set tension to the prestressed steel bars using tensioning equipment, followed by the use of a pipe mold to complete the pipe pile formation. Currently, there are significant shortcomings in the industry's pipe pile tensioning positioning: First, existing devices mostly rely on single friction or simple clips for anti-slip, and during tensioning, the connecting columns are prone to axial slippage due to uneven stress, leading to prestress loss and affecting the stability of the pipe pile quality. Second, the anti-slip structure has poor adjustment flexibility, making it difficult to adapt to connecting columns of different diameters and tensioning strokes. When changing pipe pile specifications, the entire anti-slip component must be replaced, which is cumbersome. Third, some devices have insufficient fit between the anti-slip components and the connecting columns, requiring repeated calibration during installation and time-consuming disassembly, thus limiting production efficiency and failing to meet the high-efficiency operation requirements of large-scale pipe pile production. Therefore, this utility model proposes an anti-slip device for prestressed pipe pile tensioning to address the shortcomings and deficiencies of existing technologies. Utility Model Content:

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a prestressed tensioning anti-slip device for pipe piles.

[0004] The technical solution adopted in this utility model is as follows: A prestressed tensioning anti-slip device for pipe piles includes a pipe mold, a front plate, and a connecting column fixed to the front plate. The anti-slip column is fixedly provided on the front side of the pipe mold, and the connecting column movably passes through the anti-slip column. Anti-slip ring grooves are uniformly arrayed along the axial direction on the connecting column. A prestressed tensioning stud is provided at the end of the connecting column, and the prestressed tensioning stud is connected to a prestressed steel bar tensioning device. The anti-slip column is provided with an anti-slip structure.

[0005] Preferably, the anti-slip structure comprises a positioning block, an anti-slip stop block, a transmission rod, a bearing, and a threaded knob. The positioning block is fixedly connected to the anti-slip post, and the anti-slip post has a movable opening extending to the axis. The anti-slip stop block is movably disposed in the movable opening. A threaded hole is provided through the positioning block, and the threaded knob is threadedly connected to the threaded hole. The threaded hole extends to the upper surface of the anti-slip post and communicates with the movable opening. The bottom of the threaded knob is connected to the transmission rod through the bearing, and the transmission rod is fixedly connected to the top of the positioning block.

[0006] Preferably, the lower end of the anti-slip block is provided as a stepped section, and the bottom of the anti-slip block is provided as an arc-shaped opening.

[0007] Preferably, the width of the anti-slip ring groove is equal to the width of the anti-slip block.

[0008] Preferably, the anti-slip structures on the anti-slip posts are arranged symmetrically in the upper and lower parts.

[0009] The beneficial effects of this utility model are as follows: This utility model, through the cooperation of the anti-slip column and the anti-slip ring groove of the connecting column, combined with the adjustable anti-slip block of the anti-slip structure, can effectively prevent the connecting column from sliding during tensioning and ensure the accurate application of prestress; the stepped section and arc-shaped opening design of the anti-slip block improves the fit with the connecting column and is compatible with connecting columns of different specifications; the threaded knob of this utility model is easy to adjust, and installation and disassembly do not require complicated calibration, which significantly improves work efficiency. The structure is simple and practical, with strong adaptability and reliability. Attached image description:

[0015] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0016] like Figure 1-5 As shown, a prestressed tensioning anti-slip device for pipe piles includes a pipe mold 001, a front plate 002, and a connecting column 003 fixed to the front plate 002. An anti-slip column 004 is fixedly provided on the front side of the pipe mold 001, and the connecting column 003 movably passes through the anti-slip column 004. Anti-slip ring grooves 310 are evenly arrayed along the axial direction on the connecting column 003. A prestressed tensioning stud 007 is provided at the end of the connecting column 003, and the prestressed tensioning stud 007 is connected to the prestressed steel bar tensioning device 005. An anti-slip structure 006 is provided on the anti-slip column 004.

[0017] Start the prestressed steel bar tensioning device 005. The device applies axial tension to the connecting column 003 through the prestressed tensioning stud 007. The connecting column 003 drives the front plate 002 to tension the prestressed steel bars in the tube mold 001. Then, the anti-slip structure 006 limits the connecting column 003.

[0018] Further optimizations to this solution include: Figure 1-5 As shown, the anti-slip structure 006 consists of a positioning block 610, an anti-slip stop block 620, a transmission rod 630, a bearing 640, and a threaded knob 650. The positioning block 610 is fixedly connected to the anti-slip column 004. The anti-slip column 004 has a movable opening 401 extending to the shaft center. The anti-slip stop block 620 is movably disposed in the movable opening 401. A threaded hole 611 is provided through the positioning block 610. The threaded knob 650 is threadedly connected to the threaded hole 611. The threaded hole 611 extends to the upper surface of the anti-slip column 004 and communicates with the movable opening 401. The bottom of the threaded knob 650 is connected to the transmission rod 630 through the bearing 640. The transmission rod 630 is fixedly connected to the top of the positioning block 610.

[0019] After the prestressed steel bar tensioning equipment 005 tensions the steel bars, the threaded knob 650 of the anti-slip structure 006 is rotated. Because the threaded knob 650 is threadedly engaged with the threaded hole 611 of the positioning block 610, the knob moves downward along the axial direction of the threaded hole 611 when it rotates. This pushes the transmission rod 630 through the bearing 640, causing the anti-slip block 620 to move downward within the movable opening 401 until the arc-shaped opening 622 at the bottom of the anti-slip block 620 is fully embedded in the anti-slip ring groove 310 of the connecting column 003. At this time, the stepped section 621 of the anti-slip block 620 fits against the step on the inner wall of the movable opening 401, limiting the excessive downward movement of the anti-slip block 620 and ensuring that the anti-slip block 620 is tightly engaged with the anti-slip ring groove 310, thus preventing the connecting column 003 from radially shifting.

[0020] Further optimizations to this solution include: Figure 1-5 As shown, the lower end of the anti-slip block 620 is provided with a stepped section 621, and the bottom of the anti-slip block 620 is provided with an arc-shaped opening 622. The arc-shaped opening 622 is adapted to the anti-slip ring groove 310, and the contact area is increased after the engagement.

[0021] Further optimizations to this solution include: Figure 1-5 As shown, the width of the anti-slip ring groove 310 is equal to the width of the anti-slip block 620.

[0022] Further optimizations to this solution include: Figure 1-5As shown, the anti-slip structure 006 on the anti-slip column 004 is symmetrically arranged vertically. Because the anti-slip block 620 is inserted into the anti-slip ring groove 310 and the anti-slip column 004 is fixed to the tube mold 001, it can effectively prevent the connecting column 003 from sliding along the axial direction. At the same time, the anti-slip structure 006 arranged vertically and vertically makes the connecting column 003 bear force evenly, avoiding deformation of the connecting column or failure of anti-slip due to force on one side.

[0023] The positional relationships described in the figures are for illustrative purposes only and should not be construed as limiting this patent. Clearly, the above embodiments of this utility model are merely examples to clearly illustrate the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of the claims of this utility model.
