Overturn-resistant self-elevating platform pile shoe

Abstract

The invention discloses an overturn-resistant self-elevating platform pile shoe which comprises an iron-plate-shaped hollow flat circular shell body connected by an upper top board and a lower bottom board. At least three tubular sliding ways fixedly connected with the shell body are horizontally arranged along the circumference wall of the shell body in an equally spaced mode; the front end of each tubular sliding way is provided with a limiting ring and a sealing ring, the rear end of each tubular sliding way is provided with a flange, a hydraulic oil cylinder and at least one section of telescopic pipe are sequentially arranged from the rear end to the front end, one end of a piston rod of the hydraulic oil cylinder is connected with a reinforced bar inside the shell body, a rod head arranged at the other end of the piston rod is connected with the inner end face of the front end of the telescopic pipe, the front end of the telescopic pipe is closed, and the rear end of the telescopic pipe is provided with a flange; the upper top board of the shell body is further provided with a watertight stuffing box, a watertight door is arranged at the bottom of the lower bottom board, and the hydraulic oil cylinder is communicated with a hydraulic servo system installed on a self-elevating platform through a high-pressure oil pipe. The overturn-resistant self-elevating platform pile shoe has the advantages of being flexible in operation, safe, reliable, resistant to overturning and sliding and strong in puncturing capacity.

Description

technical field [0001] The invention relates to a self-elevating ocean platform equipment, in particular to a spud shoe applied to the self-elevating ocean platform. It belongs to the field of marine engineering machinery. Background technique [0002] The spud shoe is a device installed under the truss legs of the jack-up platform. Its function is to transmit the force of the legs to the seabed soil and support the entire platform through the legs. Due to the mechanical independence between the various spud cans of the platform, the platform supported by the spud can is more adaptable than the platform supported by the ground (sinking pad), which can work on uneven seabed or slightly inclined sea area. [0003] At present, under the conditions of soft seabed and deep pile insertion, the traditional spud can is similar to an enlarged "discus"; increasing its diameter improves the bearing capacity of the spud can, but it will make it difficult to lift the pile, and even the ...

AI Technical Summary

Problems solved by technology

During the pile insertion process, the spud can is quickly inserted in a cylindrical shape by shrinking the steel skeleton. After reaching the target depth, the steel skeleton is opened to expand the bearing area of ​​the spud can. However, because its own structure is a strip bracket, the internal Lack of stiffeners, etc., so, in the case of the same radius as the traditional spud can, its bearing capacity is reduced, and the hinged structure also reduces the strength of the spud can; in addition, the internal design of the transparent spud can is not conducive to hydraulic pressure Cylinder work, the reliability of the spud can is poor, so it is difficult to put into use in practice
