Embodiment Construction

[0040] The method for turning over of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the scope of protection of the present invention cannot be limited by this.

[0041] like Figure 5-Figure 15 As shown, the present embodiment is used for the method of subsection and total section turning over, and the method of turning over comprises the following steps:

[0042] S1, according to the weight of the small section A is 113t, and the B-type lifting ring is used as the main hook, four B-40T lifting rings are needed. Determine the type and number of Type B lifting rings, and then obtain the installation diagram of Type B lifting rings according to the hull structure. According to the distribution of the center of gravity, Type B lifting rings should be placed on FR197, FR201, FR211, and FR215 ribs According to the structural characteristics of the turning tool, the fixed bottom plate must...

Abstract

The invention discloses a method for turning over in subsections and total sections. According to the method, B-type lifting rings of corresponding tonnage are selected according to the weight center of gravity of the subsections and the total section, and B-type suspension rings with lighter weight are installed on the rebates of the subsections and the total section. Lifting ring, pull the turning tooling to the position of the segmental and general segmental rings, when the center line of the tooling connecting ear plate hole and the segmental and total segmental ring holes is basically on the same straight line, insert the connecting pin, screw on the fastening nut, Insert the cotter pin. When the section and the total section need to turn over, connect the hook to the lifting part structure and tighten it slowly, so that the active top plate of the tooling can be attached to the installation plane of the lifting ring. After turning over the subsection and the total section, loosen the hook, pull out the connecting pin, remove the tooling, and recycle it. The invention greatly reduces the installation time of turning over suspension rings, reduces the workload of welding and cutting and grinding of suspension rings, improves the turning efficiency of sections and total sections, and saves costs.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a method for turning over in sections and total sections, using B-shaped lifting rings instead of D-shaped lifting rings to turn over. Background technique [0002] During ship construction, D-shaped lifting rings need to be installed when the subsections and the total section turn over, such as Figure 1-Figure 4 As shown, the current installation process is as follows: first install the horse board, pull the D-shaped lifting ring close to the reverse side of the segment with a chain block, and the construction personnel weld the D-shaped lifting ring to the general segment of the segment through overhead welding. [0003] This method has the following drawbacks: [0004] First, due to the heavy weight and complex structure of the D-shaped lifting ring, and it is often installed in reverse, overhead welding is required, and the installation workload is heavy. [0005] Second, the D-...
