Embodiment

[0022] An embodiment of the present invention provides a latch leg for an offshore lifting platform, see figure 1 , the bolt leg 1 is provided with several stages of pin holes 3 along the axis 2 of the bolt leg, and the pin holes 3 of each stage include 4 pin holes 3, and the pin holes 3 of each stage are along the The direction of the outer contour line of the cross-section 4 is arranged at intervals, and the distance between the two pin holes on the same straight line along the axis 2 of the pin leg in the pin holes 3 of two adjacent stages is equal, and the pin holes 3 of each stage It is divided into two layers, and the cross-sections 4 of the bolt legs where the pin holes 3 of different layers are located are different. Among them, the pin hole 3 of each level corresponds to one rising or falling action of the marine lifting platform, and the pin hole 3 of two adjacent levels is located between the two pin holes 3 on the same straight line along the axis 2 of the pin leg....

Abstract

The invention discloses a pin pile leg for an offshore lifting platform and belongs to the technical field of offshore engineering equipment. A plurality of stages of pin holes are arranged on the pin pile leg along the axis direction of the pin pile leg, each stage of pin holes comprises a plurality of pin holes, each stage of pin holes is arranged at intervals along the direction of the outer contour line of the cross section of the pin pile leg, distance between every two pin holes of two adjacent stages of pin holes on the same line towards the axis direction of the pin pile leg is equal, each stage of pin holes is divided into at least two layers and the cross sections of the pin pile leg with the pin holes at different layers are different. By distributing each stage of pin holes which are distributed in the same cross section of the pin pile leg at at least two layers, the number of pin holes in the same cross section is reduced and the section area and the section modulus of the cross section of the pin pile leg is increased, so that reinforcing measures such as increasing the wall thickness of the pin pile leg for guaranteeing the technical requirement on the pin pile leg are not needed and the weight and the cost of the pin pile leg are reduced.

Description

technical field [0001] The invention relates to the technical field of ocean engineering equipment, in particular to a pin leg used for an ocean lifting platform. Background technique [0002] At present, the domestic marine lifting platform generally adopts the hydraulic bolt type, and the marine lifting platform includes a bolt leg, an upper bolt, a lower bolt, a lifting cylinder, and a hydraulic station. [0003] The existing pin legs are provided with several levels of pin holes along the axial direction of the pin legs, and the pin holes of each level include a plurality of pin holes, and the pin holes of each level are located on the same cross section of the pin legs, The distance between the two pin holes located on the same straight line along the axial direction of the pin leg in the pin holes of two adjacent stages is equal. [0004] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior a...
