Manufacture method for steel structure lifting system

Abstract

The invention discloses a manufacturing method for a steel structure lifting system, which comprises the following steps: S1 constructs a vertical universal foundation pit under the ground plane; S2 after the shape of foundation pit is fixed, the vertical lifting guide rail is erected on the perimeter wall of the foundation pit, and the lifting platform is constructed on the base of the foundationpit; S3 the pre-constructed lifting system is divided into several lifting monomers with equal length in the vertical direction by design; S4 controls the lifting platform and the ground plane level,and builds the first lifting unit vertically up on the lifting platform. After completion, controls the lifting platform to descend the length of a single lifting unit to make the top of the first lifting unit level with the ground plane; and then on the basis of the first lifting unit, the second lifting unit is constructed, and after completion, descends the length of a single lifting unit to make the top of the second lifting unit level with the ground plane; in this way, the final lifting unit is constructed; S5 controls the lifting platform in the foundation pit to level with the groundplane when rising upward to the lifting platform.

Description

technical field [0001] The invention relates to the field of steel structures, in particular to a method for manufacturing a steel structure lifting system that ensures safety, reduces production costs and has strong applicability. Background technique [0002] The lifting system is widely used in various jack-up platforms, such as jack-up drilling platforms, wind power installation ships (platforms), salvage, drilling, piling, riprap leveling and other construction operation platforms, pile insertion, pile extraction, platform rise and fall , and a very complex set of devices that can fix the platform at a certain height. The jack-up drilling platform has legs that can be raised and lowered freely. During operation, the legs extend down to the seabed, stand on the seabed, use the legs to support the hull, and keep the bottom of the hull a certain distance from the sea surface (air gap) . It is composed of platform structure, pile legs and lifting mechanism. The main hull ...

Problems solved by technology

This places a high requirement on the height of the lifting system, so the production process of the traditional lifting system basically requires high-altitude operations, which leads to a greater threat to the safety of production workers. The lifting system of each project needs to be built separately, and the production cost High, poor applicability and costing material resources to build a production platform, which greatly increases production costs
