Subsection assembly auxiliary tool

Abstract

The invention discloses a subsection assembly auxiliary tool which is used in cross section closure in a manufacturing process of a pile leg on a drilling platform. The subsection assembly auxiliary tool is characterized in that in a manufacturing process of a quadrangular pile leg with a single rack on a self-elevating drilling platform, the pile leg is required to be manufactured by sections and then is hoisted onto a slipway, and the sections of the pile leg are connected one by one and the closure is carried out from the bottom up; the construction of a scaffold on the very high pile leg is a big problem, so that a construction platform is arranged at each subsection closure seam, hanging ropes are arranged at the peripheries of the construction platforms by employing a pile leg structure for hanging the outer sides, fixture tools are arranged inside for fixing the inner sides, clamping bars and connecting devices are arranged at rack structures for fixing the four corners, and four platforms are fixed to the pile leg for the cross section closure at the periphery. The subsection assembly auxiliary tool has the beneficial effects that the construction problem of the cross section closure of the pile leg in a high position is solved, a large number of scaffolds and a construction period for the cross section closure are saved substantially, the construction safety is improved, and a new pile leg closure technology is created.

Description

technical field [0001] A segmented assembly auxiliary tooling relates to the technical field of tooling in which pile legs with a single rack are assembled into whole pile legs during the manufacturing process of an offshore drilling platform. Background technique [0002] Since the pile legs are used to support the offshore platform, their length determines the depth of drilling and the operating area, so the pile legs of the current offshore platform are getting longer and longer, ranging from hundreds of meters to hundreds of meters, and the size of the cross-sectional area It is directly related to the size, economic benefit and value of the platform, so the design should reduce its cross-sectional area as much as possible, and the construction difficulty and The material and manpower consumption is very huge. In order to ensure the safety of personnel, the existing technology often consumes a lot of scaffolding to ensure the closure of the general section. The construct...

Problems solved by technology

[0002] Since the pile legs are used to support the offshore platform, their length determines the depth of drilling and the operating area, so the pile legs of the current offshore platform are getting longer and longer, ranging from hundreds of meters to hundreds of meters, and the size of the cross-sectional area It is directly related to the size, economic benefits and value of the platform, so the design should minimize its cross-sectional area, and the construction difficulty and The material and manpower consumption is huge. In order to ensure the safety of personnel, the existing technology often consumes a lot of scaffolding to ensure the closure of the general section. The construction period is long, the safety is not easy to guarantee, and the construction is extremely difficult.
