Embodiment Construction

[0031] Below, the present invention will be clearly and completely described through the preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0032] Such as figure 1 As shown, a leg displacement method involved in this embodiment includes the following steps:

[0033] S 1 1. Fixedly connecting the first overall group and the second overall group to complete the assembly of the pile legs.

[0034] Such as figure 2 As shown, in this embodiment, since the total number of legs is 3, the first group 101 and the second group 102 that make up the legs are 3 respectively. The three first general groups 101 are arranged at predetermined fixed positions, and the tops of the three first general groups 101 are provided with tie rods 1011 , and are detachably connected through the tie rods 1011 . The three first general groups 101 form a whole, which enhances its torsion resistance.

[0035] Afterwards, the three second general groups 102 ar...

Abstract

The invention discloses a pile leg shifting method. The pile leg comprises a first main group and a second main group. The pile leg shifting method is characterized by comprising the following steps: S1, fixedly connecting the first main group and the second main group so as to finish the assembly of the pile leg; S2, shifting the pile leg to a wharf; and S3, shifting the pile leg to a pile leg fixing position through a lifting sling so as to finish the fixing and mounting of the pile leg. According to the shifting method provided by the invention, the upper and lower two main groups of pile legs are assembled at a time, and then shifted through shifting equipment, such as a docking block and carried by a floating crane together, so that the condition that the pile leg main groups are assembled, shifted and finally mounted at a destination is avoided, and the carrying time of the pile legs can be saved.

Description

technical field [0001] The invention relates to a displacement method of a pile leg assembly. Background technique [0002] Pile legs are supporting devices used to support drilling platforms or other offshore engineering equipment. Due to the volume and quality of the pile legs are relatively large. Moving and hoisting pile legs is a comprehensive construction that requires the mobilization of various heavy equipment. At present, there are mainly two loading methods in the process of leg displacement. One is to send the legs to the designated position through the platform itself to complete the loading, and the other is to use a floating crane for loading. Among them, the displacement and loading of floating suspension legs are easier to realize. However, due to the small number of floating cranes that can meet this requirement in China at present, the process of carrying and shifting the pile legs is time-consuming and laborious. At present, both at home and abroad, a ...
