[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Refer to the instruction manual appendix Figure 1-5 This utility model provides a PHC pipe pile joint anti-misalignment device, including a positioning component for preventing misalignment of the PHC pipe pile joint; the positioning component includes two front and rear corresponding fixed clamps 4 and two front and rear corresponding movable clamps 5, the movable clamps 5 being disposed on the top of the fixed clamps 4; multiple spaced positioning plates 6 are installed between the two front and rear corresponding fixed clamps 4 and between the two front and rear corresponding movable clamps 5, the protective wire mesh 1 being sleeved on the outside of the multiple positioning plates 6; the fastening bolt 3 located at the bottom of the movable clamp 5 extends into the interior of the fixed clamp 4, the fastening bolt 3 being threadedly connected to the fixed clamp 4, and the fastening bolt 3 located at the bottom of the fixed clamp 4 extending into the interior of the movable clamp 5, the fastening bolt 3 being threadedly connected to the movable clamp 5.

[0025] During use, the staff will put the movable hoop 5 and the fixed hoop 4 on the outside of the two PHC pipe piles to be assembled, and then use the positioning plate 6 to support the movable hoop 5 and the fixed hoop 4, thereby limiting the PHC pipe piles during assembly, ensuring the stability of the PHC pipe piles during assembly, and avoiding skewness or misalignment.

[0026] Meanwhile, to improve the assembly stability of the movable hoop 5 and the fixed hoop 4, it is necessary to enhance the tightness of the connection between the movable hoop 5 and the fixed hoop 4, such as... Figure 4 and 5As shown, movable seats 10 are installed at both ends of the movable hoop 5, and a fixing bolt 11 is provided on the top of the movable seat 10. The bottom end of the fixing bolt 11 passes through the movable seat 10 and extends to the bottom of the movable seat 10. Fixing seats 12 are installed at both ends of the fixing hoop 4, and a fixing groove 13 is opened on the top of the fixing seat 12. The bottom end of the fixing bolt 11 extends into the inside of the fixing groove 13. The fixing bolt 11 is threadedly connected to the fixing groove 13. Through the threaded connection between the fixing bolt 11 and the fixing groove 13, the movable seat 10 and the fixing seat 12 can be assembled and fixed together. This can enhance the tightness of the connection between the movable hoop 5 and the fixing hoop 4, avoid the situation of loosening and separation, and also improve the positioning stability of the movable hoop 5 and the fixing hoop 4 for the PHC pipe pile.

[0027] To improve assembly safety, such as Figure 1-3 As shown, the positioning component is provided with two sets of protective components to prevent injury from flying objects; each set of protective components includes a protective wire mesh 1, which is sleeved on the outside of the positioning component. Two mirror-distributed connecting seats 2 are installed inside the front and rear ends of the protective wire mesh 1, and two fastening bolts 3 are provided between the two corresponding connecting seats 2. The ends of the two fastening bolts 3 that are far apart extend to the side of the two connecting seats 2 that are far apart.

[0028] In use, workers use fastening bolts 3 to attach two protective wire meshes 1 to the outside of the movable hoop 5 and the fixed hoop 4 respectively. If the positioning component breaks due to assembly error at the PHC pipe pile joint, the damaged positioning component is prone to generating flying debris. This flying debris has a certain kinetic energy and can easily damage other equipment and facilities in the surrounding area or cause harm to personnel, thus affecting operational safety. At this time, the protective wire meshes 1 can be used to block the impact of the flying debris, preventing it from flying directly to the surrounding area and establishing a safety barrier, greatly reducing the risk of workers being hit by flying debris, thereby ensuring the operational safety of this utility model.

[0029] At the same time, to prevent the protective wire mesh 1 from shaking or shifting, it is necessary to limit and fix the protective wire mesh 1, such as... Figure 1-3 As shown, the protective wire mesh 1 has multiple spaced limiting holes 7 on both the front and rear ends. Each limiting hole 7 has a limiting post 8 inside. The end of the limiting post 8 near the protective wire mesh 1 passes through the limiting hole 7 and is fixed together with the positioning plate 6. By engaging the limiting post 8 with the limiting hole 7, when the worker assembles the protective wire mesh 1, the protective wire mesh 1 can be limited to the outside of the positioning plate 6 through the engagement of the limiting hole 7 and the limiting post 8, so as to prevent the protective wire mesh 1 from being skewed or offset.

[0030] To improve the ease of assembling the protective wire mesh 1, sufficient space is needed to rotate the fastening bolts 3, such as... Figure 1-3As shown, both ends of the protective wire mesh 1 are provided with through holes 9, which are used to adjust the space between the two protective wire meshes 1 to facilitate the operation of the fastening bolts 3. By setting the through holes 9, a certain space can be released for the workers to put their hands into the protective wire mesh 1, which makes it easier for the workers to assemble the fastening bolts 3, thereby improving the convenience of assembling the fastening bolts 3.

[0031] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
