Problems solved by technology
If the judgment of the contact position between the pin and the leg hole is wrong, the lifting system will not work, and the platform is already on the sea level at this time. If the seawater is facing high tide at this time, it may cause the seawater to submerge the platform, resulting in major accidents.

A device and method for detecting the position of a bolt and a leg hole. By setting a fixed contact mechanism in a branch cylinder of a packaging cylinder, the movable contact mechanism slides and cooperates with the packaging cylinder, and the thimble of the movable contact mechanism protrudes out of the packaging cylinder to adjust The mechanism conflicts with the movable contact mechanism. The movable contact at the end of the thimble corresponds to the fixed contact. The upper surface and the lower surface of the pin ends of the fixed ring beam and the movable ring beam of the lifting system are provided with corresponding detection holes. The device is located in the detection hole and electrically connected with the lifting system. The invention overcomes the problem that the original offshore platform lifting system manually observes the pressure of the oil cylinder and the displacement of the oil cylinder to judge the switching of working conditions, which is easy to make wrong judgments, cause the system to fail to work, and cause major accidents on the flooded platform. It has the characteristics of simple structure, switching working conditions through the signal transfer of the detection device on the upper surface and the lower surface of the bolt, avoiding the misjudgment of the contact position between the bolt and the leg hole and causing the lifting system to fail to work, flexible operation, safe and reliable.
Description
technical field [0001] The invention belongs to the technical field of offshore platforms, and relates to a device and method for detecting the position of a bolt and a leg hole. Background technique [0002] With the continuous development of marine technology, people exploit and utilize marine resources more and more widely. Among them, the offshore platform is one of the main supporting equipment. The offshore platform is generally equipped with a corresponding lifting system. The common lifting systems of the offshore platform include friction winch type, rack and pinion type and hydraulic pin type. Among them, due to the simple structure and relatively low manufacturing cost of the hydraulic pin-type lifting system, the pin-type lifting system is widely used on offshore platforms. [0003] The main operation process of the offshore platform of the hydraulic bolt lifting system is as follows: navigating to the destination, lowering the legs, pre-ballasting, raising the ...
