Closing process and positioning tooling of an offshore booster station

Abstract

The embodiment of the present invention discloses a closing process and positioning tool for an offshore step-up station, including: opening a notch inward along the central axis of the web on the side of the web protruding from the flange plate in the steel plate , extend the other side of the steel plate outward along the central axis of the web and install a positioning tool that is away from one end of the steel plate protruding from the outside of the flange plate of the web; One end of the steel plate is provided with a traction opening from the end face inward along the axis of the web; one end of one of the steel plates with a notch is inserted into the traction opening in the positioning tool installed on the other steel plate to the two The opposite webs of the above-mentioned steel plates are bonded together; multiple bonded steel plates are welded to close the offshore booster station. The positioning tool includes a plate body, a traction port and an installation port provided at both ends of the plate body. It achieves the effect of smooth butt joint and avoids deformation of the welding place during the welding process.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of closure of an offshore booster station, in particular to a closing process and a positioning tool of an offshore booster station. Background technique [0002] The offshore booster station is a transfer station and key hub for centralized boosting and transmission of wind farm power, and it is responsible for carrying the core electrical equipment of the wind farm. I-beam splicing structure. [0003] However, according to the regulations in GB50205, the distance between the flange plate seam and the web seam of the welded H-shaped steel should not be less than 200mm. The web plate and the flange plate at the location are not on the same surface, which will lead to the need to dig out the steel plate during the closing process, and once the digging is done, the two will be directly connected, which is not only difficult to connect, but also the work of welding The amount will al...

Problems solved by technology

[0003] However, according to the regulations in GB50205, the distance between the flange plate seam and the web seam of the welded H-shaped steel should not be less than 200mm. The web plate and the flange plate at the location are not on the same surface, which will lead to the need to dig out the steel plate during the closing process, and once the digging is done, the two will be directly connected, which is not only difficult to connect, but also the work of welding The amount will also increase greatly, resulting in a great waste of manpower and material resources

Moreover, the way of direct butt jointing of steel plates is more likely to cause deformation problems such as curling of steel plates due to welding stress and other problems during the later welding process, especially in the process of producing large-scale equipment such as offshore booster stations

[0004] In the prior art, the method of welding the steel plate after treatment is often still adopted. For example, the patent No. CN104923894A and CN104741744A all directly weld the steel plate, and the patent No. CN108817865A especially welds the steel plate. Material improvement, this method will undoubtedly greatly increase the manufacturing cost, and not every manufacturer and user of offshore booster stations has such a huge strength to remanufacture new steel plate materials
