Example Embodiment

[0018] like figure 1 As shown, the present invention discloses a technique for standing up on the ground in section 1, and the structure involved in the section includes section 1, a pair of first lifting lugs 2 and fourth lifting lugs respectively arranged on the sides of the two major axes of section 1. Lifting lug 3 , a pair of second lifting lug 4 and third lifting lug 5 arranged on the same minor axis side of segment 1 .

[0019] When turning over in the above subsection 1, the supporting force of the ground is used to reduce the lifting load of the crane, so as to achieve the purpose of turning over. The specific steps are as follows:

[0020] (1) Production of protective cover for turning over on the ground: I-shaped steel is used, and the I-shaped steel is bent into a U-shaped structure that matches the end of the segment to complete the production of protective cover for turning over on the ground;

[0021] (2) Install the turn over protective cover: such as figure...

Abstract

The invention relates to a touchdown turning process of a subsection. During turning, a first steel wire rope and a second steel wire rope are respectively connected with a first lug on the side of a long shaft and a second lug on the side of a short shaft on the same side of the subsection; the first steel wire rope is released slowly by retracting and releasing of the first and second steel wire ropes; meanwhile, a third steel wire rope is connected with the other third lug positioned on the short shaft of the subsection to ensure that the third lug is stressed and a lower foot point of a touchdown turning protective sleeve touches down; then, when the foothold point of the touchdown turning protective sleeve touches down, the touchdown turning protective sleeve slowly rotates to ensure that the subsection is vertical; finally, the second steel wire rope is released slowly, and a fourth lug on the side of the other long shaft is connected with a fourth steel wire rope and the fourth lug is stressed; an upper foot point of the turning protective sleeve touches down and rotates, the subsection keeps flat, and the turning of the subsection is completed. The touchdown turning process of the subsection has the advantages that the cost is reduced and the turning efficiency is increased.

Description

technical field [0001] The invention discloses a staged turning process on the ground, specifically a cost-saving and efficient turning process on the ground. Background technique [0002] On a ship, the segment located on the larger and heavier double bottom or side is often turned over 180° during the manufacturing process due to the need for assembly and welding to complete the assembly and welding work on the other side. [0003] like figure 1 As shown, the above-mentioned segment 1 is a rectangular structure made of I-shaped steel, and the first lifting lug 2 and the fourth lifting lug 3 are respectively arranged on the sides of the two major axes, and the second lifting lug is symmetrically arranged on the side of the short axis. Ear 4 and the third lug 5, this segment needs to be turned over 180° horizontally during the installation process. [0004] When the section is close to the lifting limit of the crane and needs to be turned over, usually for the sake of ...
