Problems solved by technology

[0003] During the piling process, if there is a slight skew, the pile holder needs to be readjusted. At present, the method of adjusting the pile holder at sea is to use the ship to drive the pile holder to adjust the pile. The efficiency is low and the adjustment is difficult. Therefore, Need a kind of improved technology urgently to solve this problem that exists in the prior art

Abstract

The invention discloses a large-deviation-rectifying-force pile holding machine and an operation process thereof. The machine comprises a ship deck, double H-shaped steel rails, an upper platform, round stand columns, a stand column assembly, a pull cable, left pile claw arms, right pile claw arms, a pile claw tail oil cylinder, middle contacts, a stand column stretching-out box body, a locking device, end contacts, end plug pin mechanisms and tail positioning contacts. The double H-shaped steel rails are fixedly mounted on the upper surface of the ship deck; the upper platform is fixedly mounted at the top ends of the double-H-shaped steel rails; two round stand columns and the stand column assembly are fixedly installed on the upper surface of the upper platform; the number of the left pile claw arms and the number of the right pile claw arms are both two; the middle contacts, the end contacts and the tail positioning contacts are mounted on the inner sides of the left pile claw armsand the right pile claw arms; and one end, away from the connecting round stand column, of the stand column stretching-out box body is flexibly connected with a locking device, and one end, away fromthe connected round stand column, of each left pile claw arm is equipped with the end plug pin mechanism. According to the invention, the structure and the operation process are reasonable, deviationrectification can be conducted in time, the working efficiency is greatly improved, the applicability is high, and the overall service life is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of pile-holding machines, in particular to a pile-holding machine with large deviation-correcting force and its operating process. Background technique [0002] One of the difficulties in the construction of offshore wind farms is the installation of piles. The piles with a diameter of 3 to 8 meters and a weight of 500 to 2,500 tons are inserted into the underwater mud with a pile hammer. The hoisting height (about 80-120 meters), hoisting weight and position requirements must also ensure the verticality of the pile, that is, perpendicular to the sea level. [0003] During the piling process, if there is a slight skew, the pile holder needs to be readjusted. At present, the method of adjusting the pile holder at sea is to use the ship to drive the pile holder to adjust the pile. The efficiency is low and the adjustment is difficult. Therefore, A kind of improved technology is urgently needed to solve this p...
