[0002] The traditional method for driving steel sheet piles mainly uses an excavator combined with a pile driving arm to drive the piles, or a crawler crane combined with a vibratory hammer to vibrate and drive the steel sheet piles into the ground. This construction method will generate relatively large noise during construction. At the same time, due to the vibration effect, it will have a greater impact on the surrounding adjacent structures, underground pipelines and the verticality of the pile body.

[0003] In the prior art, the Chinese utility model patent document with the authorization announcement number of CN219386303U discloses a static pile press applicable to different specifications of steel sheet piles, which can walk on its own while pressing piles on the top of the steel sheet piles that have been driven. When this static pile press is under construction, it needs to be supplied with steel sheet piles in cooperation with a lifting device. The hook of the lifting device is connected to the steel sheet pile through a steel wire rope and lifted to the static pile press. This lifting method is prone to slipping and poses a safety hazard.

[0004] Therefore, it is necessary to design a construction auxiliary tool for a river deep-water cofferdam static pile press that can stably clamp steel sheet piles, is not prone to slipping, and reduces potential safety hazards to solve the current technical problems. Summary of the Invention

[0023] As Figures 1 to 4 shown, a construction auxiliary tool for a static pressure pile driver for a deep river channel cofferdam includes a clamp body 1. A moving clamp plate 2 is slidably arranged horizontally inside the clamp body 1. A hydraulic cylinder 4 for driving the moving clamp plate 2 to reciprocate is arranged on one side of the clamp body 1. The moving clamp plate 2 and the clamp body 1 cooperate to clamp or release one end of a steel sheet pile. A hanging mechanism is arranged on the top of the clamp body 1, and the hanging mechanism is used to connect with the hook of a lifting device; in this embodiment, the hanging mechanism is connected with the hook of the lifting device, and the tool is hoisted by the lifting device. When hoisting the steel sheet pile, one end of the steel sheet pile is inserted between the moving clamp plate 2 and the clamp body 1. The hydraulic cylinder 4 is driven to move the moving clamp plate 2. The moving clamp plate 2 and the clamp body 1 cooperate to clamp and fix one end of the steel sheet pile. Then, the lifting device slowly hoists one end of the steel sheet pile, and finally the steel sheet pile is transported to the static pressure pile driver for static pressure construction; wherein one end of the steel sheet pile is driven by the hydraulic cylinder 4 to move the moving clamp plate 2. The moving clamp plate 2 and the clamp body 1 cooperate to clamp and fix one end of the steel sheet pile. The hydraulic cylinder 4 can provide a large clamping force to stably clamp one end of the steel sheet pile, which can avoid slipping during hoisting and reduce potential safety hazards; the construction auxiliary tool for the static pressure pile driver for the deep river channel cofferdam can be directly connected with the hook of the crane through the hanging mechanism, and can be directly hung and used, which is convenient and fast and improves the convenience of use.

[0024] In some embodiments, the hanging mechanism has two parallel support plates 7 symmetrically arranged on the top of the clamp body. The bottom ends of the support plates 7 are welded and fixed to the top of the clamp body 1. A hanging rod 8 is fixed between the support plates 7. The hook of the lifting equipment can be directly hung on the outside of the hanging rod 8 for lifting, which is convenient and quick, and improves the convenience of use.

[0025] In some embodiments, a guide rod 5 is evenly arranged on one side of the movable clamping plate 2, and the guide rod 5 is connected to one side of the clamp body 1 in a sliding manner in the horizontal direction. A limit plate 6 is fixedly arranged on the end of the guide rod 5 that is away from the movable clamping plate 2. The movable clamping plate 2 cooperates with the clamp body 1 through the guide rod 5, thereby realizing the sliding of the movable clamping plate 2 in the horizontal direction inside the clamp body 1.

[0026] In some embodiments, the clamp body 1 has a top plate 13, and a support plate 12 and a fixed clamping plate 11 are arranged parallel to each other at the bottom of both ends of the top plate 13. The top plate 13, the support plate 12 and the fixed clamping plate 11 are an integrated structure, and the movable clamping plate 2 is connected to the support plate 12 in a horizontal sliding direction; specifically, the guide rod 5 and the support plate 12 are connected in a vertical sliding direction.

[0027] In some embodiments, a backing plate 3 is fixedly disposed on one side of the movable clamping plate 2 and the fixed clamping plate 11.

[0028] In some embodiments, the pad 3 is a plate structure made of PA6. The PA6 (nylon 6) material has good wear resistance and is not easy to wear during use. Anti-slip ridges 31 are evenly arranged on one side of the pad 3. By setting the anti-slip ridges 31, the friction between the pad 3 and the steel sheet pile can be increased during lifting to avoid slipping.

[0029] In some embodiments, Figure 4 As shown, the hydraulic cylinder 4 has a piston rod 41, and the end of the piston rod 41 is slidably connected to the movable clamping plate 2. A pressure sensor 9 is arranged between the end of the piston rod 41 and the movable clamping plate 2. The pressure sensor 9 can detect the clamping force of the movable clamping plate 2, and can obtain the clamping force when the movable clamping plate 2 clamps the steel sheet pile. When the clamping force reaches a certain value, the steel sheet pile is lifted to avoid the clamping force being too small, which may cause the steel sheet pile to slip during the lifting process.

[0030] In some embodiments, a sliding groove 23 is provided on the side of the movable clamping plate 2 close to the hydraulic cylinder 4, and a support tube 22 is concentrically fixedly arranged on the outer side of the sliding groove 23, and a convex ring 42 is provided at the end of the piston rod 41, and the convex ring 42 is slidably arranged inside the support tube 22 and the sliding groove 23. A retaining ring 21 corresponding to the convex ring 42 is fixedly arranged on the end of the support tube 22 facing away from the movable clamping plate 2, and the pressure sensor 9 is arranged between the movable clamping plate 2 and the end of the piston rod 41 inside the sliding groove 23. When the movable clamping plate 2 clamps the steel sheet pile, the thrust of the piston rod 41 acts on the movable clamping plate 2 through the pressure sensor 9. At this time, the pressure sensor 9 can obtain the clamping force of the movable clamping plate 2. When the movable clamping plate 2 releases the steel sheet pile, the piston rod 41 is retracted, and the end of the piston rod 41 slides in the sliding groove 23 and the support tube 22 in a direction away from the movable clamping plate 2, and the convex ring 42 abuts against the retaining ring 21, pulling the movable clamping plate 2 to move and reset, thereby releasing the steel sheet pile.

In order to avoid obscuring the concept of the present invention, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution disclosed here.
