Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a construction method of a plug-type lifting ring beam, which can solve the problem that the common lifting ring beam is installed by integral molding, and the deformation generated during the welding process cannot be well controlled. The welding deformation of the ring beam and the welding deformation of the leg piles are likely to cause problems that the two cannot cooperate well during use

Embodiment Construction

[0024] The following examples can enable those skilled in the art to understand the present invention more comprehensively, but the present invention is not limited to the scope of the described examples.

[0025] A construction method of a bolt-type lifting ring beam, the construction technology of the lifting ring beam mainly includes making upper and lower cover plates, making anti-rotation device 2, making lug plate 3 and making shaft sleeve 4, and then proceeding to general assembly, the present invention The construction technology of the lowering ring beam firstly forms the overall structure of the lifting ring beam, and then carries out the internal continuous welding of the ring beam. The specific construction steps are as follows: figure 1 Shown below:

[0026] Step 1, the construction of the lifting ring beam box: first splice the 4 arcs made into a complete lower cover plate on the pyrotechnic platform, then fix the lower cover plate on the tire frame to mark the l...

Abstract

The present invention relates to a method of constructing a plug-pin lifting ring beam, and the method mainly comprises the following construction steps of: constructing a lifting ring beam box body;forming a lifting ring beam structure and installing an anti-rotating device, namely, welding all parts after forming a frame of the lifting ring beam structure; in the construction process of the method, installation of a shaft sleeve is effectively improved in precision and a middle backing plate of a wear-resisting plate is vertically processed after being installed, so that irregular deformation caused in a welding process is eliminated and a gap between the wear-resisting plate and leg piles is ensured; the construction period of the ring beam is integrally reduced by the method so as toreduce labor cost, and thus the method has a wide large-scale production prospect.

Description

technical field [0001] The invention relates to the field of marine engineering, in particular to a construction method of a bolt type lifting ring beam. Background technique [0002] Compared with oil platforms, the lifting system of wind power installation ships is used more frequently. The ring beam lifting structure has the characteristics of light weight of the overall structure, relatively simple system and large maintenance space. It has become an excellent choice for the lifting method of wind power installation ships. The lifting cylinder has a certain buffering effect when the platform is raised and lowered, and the latch has a locking function for the platform, which greatly improves the safety performance of the platform. The use of wind power generation is very environmentally friendly, and the wind energy is huge, so it is increasingly valued by countries all over the world. my country is rich in wind energy resources, and the wind energy reserves that can be...
