[0002] When building a foundation wind turbine in a river or on the seabed, it is necessary to first sink multiple engineering piles to the bottom of the river or the seabed. At this time, the engineering piles must first be hoisted to the pile sinking point, and then the piles must be sunk. In order to ensure that the engineering piles can be smoothly inserted into the mud and the verticality of the pile body is within 3‰ during the pile sinking process, a pile stabilization platform is often used to stabilize the engineering piles. Existing pile stabilization platforms generally use clamps to fix the engineering piles. The fixing principle is to fix the telescopic mechanism on the clamp. The telescopic mechanism is telescoped in a plane parallel to the plane where the clamp is located to hold the engineering pile. Since the telescopic mechanism itself has a certain length and the telescopic length of the telescopic mechanism is limited, it is necessary to dismantle the telescopic mechanism and reinstall it for some ultra-wide engineering piles or ultra-thin engineering piles, which is very troublesome.

[0003] Therefore, a pile gripper with a hydraulic cylinder obliquely arranged is provided to solve the above-mentioned problem. Summary of the invention
