Pile leg segmented butt-joint guide device

Abstract

The invention belongs to the manufacturing field of pile legs of a self-elevating drilling platform, and particularly relates to a pile leg segmented butt-joint guide device. The pile leg segmented butt-joint guide device comprises an upper wedge block and a lower wedge block, wherein the upper wedge block comprises two upper wedge block fixed plates, two upper wedge block connecting plates and two upper wedge block guide plates which are symmetrically arranged; the outer sides of the upper wedge block fixed plates are in welded connection with a rack plate; the lower parts of the upper wedge block guide plates which are symmetrically arranged form a V shape and form a guide structure with the lower wedge block; the upper wedge block fixed plates and the upper wedge block guide plates are fixed by the upper wedge block connecting plates in a welding manner to form the upper wedge block of the guide device; and the lower wedge block comprises lower wedge block fixed plates, a lower wedge block baseplate and a pin. The pile leg segmented butt-joint guide device solves the problem of complex working process of pile leg segmented closure in the prior art and greatly facilitates the segmented closure working of pile legs.

Description

technical field [0001] The invention belongs to the field of pile leg manufacturing of self-elevating drilling platforms, and in particular relates to a piecewise butt joint guide device for pile legs. Background technique [0002] During the production process of the jack-up drilling platform pile legs, the pile legs need to be closed in sections to form the entire pile leg structure. Due to the long height and heavy weight of the pile leg sections, the rack plate of the main side tube must be fixed during the hoisting process. The thickness is relatively small compared to the size of the entire pile leg segment, and it is difficult to accurately dock the closing mouth of the pile leg segment during the hoisting process. The positioning device moves the legs to the specified position, which makes the process of closing the legs complicated, which is unfavorable for the closing of the legs. [0003] Introduce prior art such as patents and literature. Contents of the inven...

[0002] During the production process of the jack-up drilling platform pile legs, the pile legs need to be closed in sections to form the entire pile leg structure. Due to the long height and heavy weight of the pile leg sections, the rack plate of the main side tube must be fixed during the hoisting process. The thickness is relatively small compared to the size of the entire pile leg segment, and it is difficult to accurately dock the closing mouth of the pile leg segment during the hoisting process. The positioning device moves the legs to the designated position, which makes the process of closing the legs more complicated, which is not conducive to the closing of the legs
