Description

Pile extractor for hydraulic engineering Technical Field The utility model relates to the technical field of hydraulic engineering, in particular to a pile extractor for hydraulic engineering. Background The hydraulic engineering is a built engineering for controlling and allocating surface water and underground water in nature to achieve the aim of removing harm and benefiting. Also known as water engineering. Water is an essential valuable resource for human production and life, but its naturally occurring state does not fully meet the needs of humans. Only when the hydraulic engineering is built, the water flow can be controlled, flood disasters are prevented, and the water quantity is regulated and distributed so as to meet the needs of people living and production on water resources. Hydraulic engineering needs to build different types of hydraulic structures such as dams, dykes, spillways, sluice gates, water inlets, channels, raft grooves, raft ways, fishways and the like so as to achieve the aim. Through searching, the water conservancy pile pulling machine disclosed in China patent with the publication number of CN222140029 is technically characterized by comprising a bottom plate, wherein a driving mechanism is arranged on the top side of the bottom plate, a clamping mechanism is arranged in the center position of the top side of the bottom plate, a moving mechanism is arranged on the bottom side of the bottom plate, the driving mechanism comprises a hydraulic cylinder, a hydraulic rod is slidably arranged in the hydraulic cylinder, a supporting plate is fixed at the bottom end of the hydraulic rod, a supporting seat is fixed at the top end of the hydraulic cylinder, a connecting rod is rotatably arranged on the supporting seat, a limiting ring is arranged at the top end of the connecting rod, a connecting seat is fixedly arranged on the circumferential surface of the limiting ring, screws are rotatably inserted on the circumferential surface of the limiting ring, after the pile body is clamped and fixed, the hydraulic cylinder is controlled to extend an inner hydraulic rod to pull up the pile body, when the hydraulic rod extends to the longest, the bottom plate is moved to the ground again, and at the moment, the top end of the pile body is positioned on the inner side of the limiting ring, and the screws are rotated to enable the pile body to be abutted against the surface of the pile pulling machine, so that a supporting effect is achieved, and the problem that the existing pile pulling machine easily tilts due to gravity shifting is solved.
