A connection device and connection method for a marine spud leg and a spud shoe

Abstract

The invention provides a pile leg and pile shoe connecting apparatus and method for a ship. The apparatus comprises a pile leg and a pile shoe, the pile leg comprises a latch hole, and a support sleeve is arranged on the inner side of the latch hole. The support sleeve internally comprises a pressure sensor, a manipulator, a compression spring and a connecting pin. The pile shoe comprises a pile shoe hole, and the position of the pile shoe hole corresponds to the position of the support sleeve when the pile leg is inserted into a guiding groove of the pile shoe. A hoisting device hoists the pile leg so as to connect the pile leg and the pile shoe, the pile leg slides downwardly along the guiding groove of the pile shoe, the compression spring compresses the connecting pin during a downward sliding process of the pile leg, then the connecting pin shrinks and is disposed inside the support sleeve. When the connecting pin reaches the pile shoe hole, the compression spring pushes the connecting pin into the pile shoe hole. The connecting apparatus is simple in structure, is convenient to install and maintain, is detachable, and improves the stability of the connection between the pile leg and the pile shoe.

Description

technical field [0001] The invention relates to the technical field of manufacturing marine engineering equipment, in particular to a connection device and connection method for marine spud legs and spud cans. Background technique [0002] With the increasing consumption of non-renewable energy and environmental protection issues have become increasingly prominent. People began to seek an environmentally friendly and clean renewable energy to meet human needs for energy. As a clean and renewable new energy, wind energy has been paid more and more attention, and wind power generation has gradually become one of the largest and most mature power generation methods in new energy technologies. The construction of offshore wind farms, whether it is the installation of wind turbines or basic equipment, requires transport vehicles with corresponding capabilities to transport them to the wind farm site, and is equipped with lifting equipment and positioning equipment suitable for v...

AI Technical Summary

Problems solved by technology

[0003] At present, marine spud boots are mainly connected to the spud legs by welding. For some marine steels, the weldability is poor, and cracks are prone to occur in the weld area of ​​ultra-thick plates, which seriously affects the connection performance of spud legs and spud boots.

The spud boots work in the complex seabed environment all the year round, and they are prone to failure or damage. The welding method is not removable, which brings a lot of inconvenience to the replacement and maintenance of the spud boots

[0004] The present invention is aimed at the connection device of the marine spud legs and spud cans in the prior art, and its connection method only uses welding to connect, resulting in poor connection performance, inconvenient installation, non-removable, and difficult maintenance.
