Problems solved by technology

However, the existing locking mechanisms are all fixed installations, that is, collision or extrusion occurs between the locking mechanism and the pile legs under the impact of sea waves, etc., so that the pile legs are stressed unevenly, so that the pile legs are deformed, and there is a huge problem. security risks

Abstract

The invention discloses an octagonal pile leg provided with a safe floating mechanism. The octagonal pile leg comprises a pile leg main body, a floating lockpin mechanism and a lockpin installation ring beam, wherein the pile leg main body comprises a platform partition board, a coaming and a guide plate; the floating lockpin mechanism comprises a locking pin assembly, a floating base, a plurality of shock absorbers and a plurality of sliding plates. The octagonal pile leg installs the floating lockpin mechanism on the lockpin installation ring beam in a suspension manner through the sliding plates and the shock absorbers, the pile leg main body is locked, and at the same time, the pile leg main body and the floating lockpin mechanism move together under impact of the sea wave, that is, the floating lockpin mechanism and the pile leg main body keep relative rest; and compared with the existing plug pin mechanism fixedly mounted on the lockpin installation ring beam, the floating lockpin mechanism avoids impact deformation of a locking pin shaft and the pile leg main body to improve safe reliability and prolong service life.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to an octagonal pile leg with a safety floating mechanism. Background technique [0002] The pile legs are an important part of the offshore operation platform. They are used to support the weight of the upper hull and bear environmental loads such as wind, waves and currents. The structural forms are mainly cylindrical pile legs and truss pile legs. There are two types of hydraulic bolt type and rack and pinion type. In the bolt-type offshore work platform, the cylinder legs and the hydraulic bolt-type lifting system are used to cooperate with each other to realize the lifting and lowering of the legs. The existing cylindrical pile legs are not easy to assemble, the space utilization rate is low, the overall strength is low, and there is a problem of stress concentration. [0003] Moreover, due to the complex and changeable offshore environment, the offshore operation ...
