Problems solved by technology
In the traditional pile pulling process, the equipment used for pulling piles and supporting piles is different. Steel wire ropes and jacks are generally used for pulling piles, and poles and jacks are used for supporting piles. To meet the design requirements, several jacks need to work at the same time, which increases the complexity and difficulty of the adjustment process of pulling piles; and the efficiency of the traditional pile pulling process is low, and the distance between piles cannot be adjusted without gaps, and it is necessary to repeatedly pull piles and piles to adjust The distance between the piles can meet the requirements

The invention relates to a pile tension device which is applied to an offshore pile foundation structure project. The pile tension device comprises a connecting rod A and a connecting rod B and also comprises a connecting cylinder connected between the connecting rod A and the connecting rod B, wherein an A-end channel and a B-end channel through which the connecting rod A and the connecting rod B penetrate are respectively arranged at the ends A and B of the connecting cylinder, and inner threads which are opposite in direction are arranged in the A-end channel and the B-end channel; one end of the connecting rod A is provided with a connecting mechanism A, and the other end of the connecting rod A is provided with an outer thread which corresponds to the inner thread of the end A of the connecting cylinder; one end of the connecting rod B is provided with a connecting mechanism B, and the other end of the connecting rod B is provided with an outer thread which corresponds to the inner thread of the end B of the connecting cylinder; and the connecting cylinder is provided with a rotation mechanism which can drive the connecting cylinder to rotate. According to the pile tension device, the zero clearance of the distance between the piles can be realized through the threaded connection between the connecting rods and the connecting cylinder, dismounting and mounting are convenient, and the construction efficiency of the offshore pile tension can be greatly improved.
Description
technical field [0001] The invention relates to a pile puller suitable for offshore pile foundation structure engineering. Background technique [0002] During the pile sinking construction of the offshore pile foundation structure, due to the influence of positioning instruments and wind and wave factors, the distance between the piles cannot fully meet the requirements of the construction drawings. After the pile sinking is completed, it is often necessary to adjust the distance between the piles by pulling the piles. In the traditional pile pulling process, the equipment used for pulling piles and supporting piles is different. Steel wire ropes and jacks are generally used for pulling piles, and poles and jacks are used for supporting piles. To meet the design requirements, several jacks need to work at the same time, which increases the complexity and difficulty of the adjustment process of pulling piles; and the efficiency of the traditional pile pulling process is low,...
