Problems solved by technology
Especially in the commissioning stage, the crew observes at the surrounding well of the pile fixing room, and it is very easy to make operational mistakes, causing the spud shoes to hit or even tear the surrounding well (bottom) of the platform, resulting in deformation of the bottom and pile legs, seriously affecting the work of the platform efficiency

A device and method suitable for detecting the position of a spud shoe in a cylindrical pile leg lifting system. The sleeve of the adjustment mechanism is connected to the base of the jacking mechanism, the limit mechanism is located in the sleeve and connected to the base, and the sealing device is covered on the sleeve. In addition, the signal detection device is located in the sealing device and connected to the cover plate of the adjustment mechanism. The ejector rod of the adjustment mechanism extends out of the base through the limit mechanism and the adjustment mechanism. When the ejector rod rises, it is detected by the signal detection device to control the start and stop of the lifting system and the lifting speed. The invention overcomes the problem that when the original pile leg is lifted, relying on the operator's intuitive judgment on the position of entering the well will easily lead to damage and deformation of the collision hull. It has the characteristics of simple structure, the set position of the spud shoes entering the surrounding well under the platform does not collide with the bottom of the ship, accurate entry into the well, effectively avoiding the deformation of the pile legs and the bottom of the ship, high lifting efficiency, and simple and convenient operation.
Description
technical field [0001] The invention belongs to the technical field of offshore platforms, and relates to a device and method suitable for detecting the position of spud cans in a cylinder leg lifting system. Background technique [0002] With the continuous development of marine technology, offshore platforms are used more and more widely, and common offshore platforms are equipped with corresponding lifting systems. Common lifting systems for offshore platforms can be divided into rack-and-pinion and hydraulic pin-type. Due to the relatively low cost of hydraulic pin-lift systems of the same tonnage, offshore wind power has widely used offshore platforms with hydraulic pin-lift systems in recent years. The hydraulic bolt lifting system is generally used in cylindrical legs, and is welded and fixed at the bottom of the legs and the spud shoe. [0003] When the offshore platform is working, the offshore platform is raised to a corresponding height from the sea level by the ...
