before piling operation, firstly measuring to obtain the side length of the pile body, then adjusting a clamping device A4, adjusting the distance between the clamping action parts 42 by the hydraulic cylinder 43 through the clamping arm 41 to ensure that the clamping action parts 42 can be attached to the pile body during operation (the upper side and the lower side of the inner end surface of the clamping action parts 42 are arc-shaped to ensure that the pile body is easier to be clamped by the clamping action parts 42, and the roller 421 rotatably connected on the clamping action parts 42 ensures that the resistance between the pile body and the clamping action parts 42 is greatly reduced, thereby being more beneficial to the falling of the pile body), since the lengths of the sides of most of the pile body interface are considered to be consistent, the synchronous rod 44 drives the synchronous slide block 411 to synchronously move the clamping arm 41, this makes it possible to achieve position adjustment of all the clamp-acting portions 42 in the clamp device a4 with only one set of hydraulic cylinders 43, reducing the weight of the device and also reducing the manufacturing cost.
