Description

Technical Field

[0001] The utility model belongs to the technical field of precast piles, and particularly relates to a clamping mechanism for hoisting precast piles. Background Technique

[0002] Precast piles are widely used in modern construction projects, mainly for foundation support and reinforcement. The hoisting of precast piles is a key step, which needs to be completed with the help of a clamping mechanism. The clamping mechanism is used to ensure the safety and efficiency of precast piles during hoisting. The clamping mechanism can accurately control the position of the precast pile to ensure its accurate placement according to the construction requirements. This is crucial for ensuring the stability of the structure and the smooth progress of subsequent construction. During the hoisting process of precast piles, stability and safety are the primary considerations. Due to the insufficient clamping force of the fixtures in the related technology, the pile body may slide or even fall during handling and rotation. This will not only pose a serious threat to the construction site safety, but also may cause equipment damage and construction progress delay. Summary of the Invention

[0004] To achieve the above object, the technical solution of the utility model is realized as follows:

[0006] The clamping structure is arranged above the fixing structure, and both the clamping structure and the fixing structure are used to fix the top of the pile body;

[0007] The two first anti-slip structures are symmetrically arranged left and right. The top of the first anti-slip structure is fixedly connected with the clamping structure, and the bottom of the first anti-slip structure is detachably connected with the fixing structure;

[0008] The two second anti-slip structures are symmetrically arranged front and back. The top of the second anti-slip structure is detachably connected with the clamping structure, and the bottom of the second anti-slip structure is fixedly connected with the fixing structure;

[0010] Furthermore, the clamping structure includes two clamping plates and two side clamping plates. The two clamping plates are symmetrically arranged front and back, and the two side clamping plates are symmetrically arranged left and right. The front and rear ends of each side clamping plate are correspondingly detachably connected to one clamping plate.

[0019] 3. The front and rear symmetric clamping plates and the left and right symmetric side clamping plates can clamp the pile body simultaneously from multiple directions, improving the overall clamping stability and safety, and effectively preventing the pile body from sliding in any direction during the hoisting process. The detachable connection between each side clamping plate and the clamping plate makes the installation and disassembly process very fast and convenient, effectively improving the construction efficiency. A plurality of strip-shaped holes for connecting the pile body are evenly distributed on the side clamping plates, and can be freely adjusted according to different sizes and specific positions of the pile body, enhancing the versatility and flexibility of the clamping structure. The upper and lower ends of the clamping plate are provided with flanges facing inwards, which can be used in cooperation with the pre-set limit grooves at the top of the pile body, greatly increasing the clamping force and effectively preventing the pile body from slipping.
