Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a pipe pile clamping mechanism. Background Technology

[0002] When geological conditions are poor and the bearing capacity of the foundation is low, pile foundations must be used. Pile foundations are used to drive piles one by one into the ground, transferring the weight of the building above to the lower soil layer with higher bearing capacity. If the lower soil layer with high bearing capacity is very deep, the friction between the pile foundation and the surrounding soil can also be used to support the weight of the building above.

[0003] Prestressed concrete pipe piles are a type of pile foundation. Different pile types are available for different geological conditions. They are mainly composed of a cylindrical pile body, end plates, and steel sleeves.

[0004] In traditional techniques, before driving pipe piles into the ground, steel wire ropes need to be manually tied to the piles. Then, a crane or other equipment is used to lift the steel wire ropes, which in turn lifts the pipe pile to the designated location for driving. This method has two drawbacks: 1. The pipe piles require manual tying, which is inefficient; 2. After tying with steel wire ropes, slippage is likely, resulting in a low safety factor and poor reliability. Utility Model Content

[0005] The purpose of this utility model is to provide a pipe pile clamping mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pipe pile clamping mechanism, comprising a mounting base, a first clamping block, a connecting base, and a second clamping block. The first clamping block is installed in the middle of the surface of the mounting base. A plurality of buffer plates are evenly laid on the inner surface of the first clamping block. First hydraulic telescopic rods are installed on both sides of the surface of the mounting base. One end of the first hydraulic telescopic rod is connected to the connecting base. A fixing frame is installed on the inner surface of the connecting base. A plurality of second hydraulic telescopic rods are evenly installed on the back of the fixing frame. A second clamping block is installed at the output end of the second hydraulic telescopic rod on the front of the fixing frame. A plurality of rubber pads are evenly laid on the surface of the second clamping block.

[0007] Preferably, the mounting base has hoist mounting holes on both sides of its top.

[0008] Preferably, the mounting base has limit grooves on both sides of the top, and the connecting base has a limit rod connected to one side of the bottom, with the limit rod engaging and slidingly connected to the limit groove.

[0009] Preferably, a plurality of friction plates are mounted on the surface of the buffer plate by fixing screws.

[0010] Preferably, a rubber pad is laid on the inner surface of the second clamping block, and a pressure sensor is installed on the surface of the rubber pad.

[0011] Preferably, the first clamping block and the second clamping block are arc-shaped, with the second clamping block facing the first clamping block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model has a simple structure and strong practicality. It only requires hoisting the clamping device above the pipe pile to be clamped through the hoist mounting hole using equipment such as a crane, and then lowering the device so that the first clamping block can be fitted onto the outside of the pipe pile. Then, the first and second hydraulic telescopic rods are manually controlled to make the second clamping block clamp the outside of the pipe pile, thus clamping the pipe pile between the first and second clamping blocks. The degree of clamping is detected by a pressure sensor. The operation is simple and convenient, and it is safer and more reliable than the traditional manual binding of steel wire ropes. By setting a buffer plate and friction plate on the surface of the first clamping block and a rubber pad on the surface of the second clamping block, the friction between the clamping device and the pipe pile can be effectively increased, thereby further improving safety.
