Pile gripper for offshore piling

Abstract

The invention relates to a pile gripper for offshore piling. The pile gripper for offshore piling is composed of a pile gripper mechanism system, a hydraulic system and an electrical control system. A large base is connected with a sliding base through a sliding rail. A cross beam is installed in a sliding groove of the sliding base. A lateral thrust cylinder is installed on the portion, between a deck and the sliding base, of a mounting base. A main thrust cylinder is installed on the portion, between the sliding base and the cross beam, of the mounting base. A hoop is installed at the front end of the cross beam. The left side and the right side of the front end of a hoop base are connected with a left hoop body and a right hoop body separately. The left hoop body and the right hoop body are connected with the two sides of the cross beam through hoop opening and closing cylinders correspondingly. The hoop is provided with a pile gripping and clamping mechanism. Two sets of locking mechanisms are installed at the front end of the left hoop body. The right hoop body is provided with pin holes corresponding to taper pins of the locking mechanisms. Each pile gripping cylinder is connected with a proportional valve and controlled to act by the proportional valve. A programmable logic controller (PLC) performs closed-loop control over the opening degree and direction of the proportional valves according to a feedback signal of a magnetostrictive displacement sensor, so that the pile gripping cylinders are controlled to perform pile jacking guidance on steel piles and keep guidance on the steel piles within a required range.

Description

technical field [0001] The invention relates to piling construction equipment for offshore wind power installation platforms (ships), in particular to a pile holding device for offshore piling, which belongs to the technical field of offshore piling and pile holding. Background technique [0002] my country's offshore wind power is still in its infancy, and many devices need to be developed and manufactured by relevant manufacturers to break through the bottleneck of offshore wind power. Among them, the piling construction of steel piles is a difficult point that offshore wind farms need to face, especially when the working water depth is large and the diameter of steel piles is large. It is more difficult to construct steel pile foundations under conditions such as high winds and high waves. The pile holding device is a professional equipment that solves the difficulties in piling construction of offshore wind power foundation steel pipe piles (hereinafter referred to as ste...

AI Technical Summary

Problems solved by technology

[0012] Aiming at the disadvantages of existing pile holders, such as large size and weight, relatively low piling efficiency, and insufficient piling safety, a pile holder for offshore piling is provided, which has a more compact structure, lighter weight, and easier operation. While being intuitive, it further improves offshore piling efficiency and piling safety
