Example Embodiment

[0024] Example: A method for turning over a duplex stainless steel P-type total section, including the following steps:

[0025] Step 1. Arrange four main turning hooks 1, four secondary turning hooks 2 and two main translation hooks 3 on the P-type general section. The four turning main hooks 1 are all arranged on the side section 4 deck. The four main turning hooks 1 respectively correspond to the four T rows 6 on the deck section 5, and the four turning main hooks 1 are on the same horizontal line, and the four turning auxiliary hooks 2 are arranged on the side of the ship. On the rib 7 of section 4, and two auxiliary turning hooks 2 are located on one side of the transversal compartment section 8, and the other two turning auxiliary hooks 2 are located on the other side of the transversal compartment section 8. The main translational hooks 3 are respectively arranged on the two T rows 6 on the deck section 5 that are closest to the transom compartment section 8, and the two m...

Abstract

The invention discloses a turning method for a duplex stainless steel P-type block, and belongs to the technical field of ship building. The method comprises the following steps that firstly, turningmain hooks, turning auxiliary hooks and translation main hooks are arranged on the P-type block; secondly, lifting hooks of a first crane are connected with the turning main hooks, lifting hooks of asecond crane are connected with the turning auxiliary hooks, and the lifting hooks of the first crane and the lifting hooks of the second crane rise; thirdly, when the rising height of the P-type block is two times the height of the P-type block, the lifting hooks of the first crane and the lifting hooks of the second crane stop rising, and the lifting hooks of the second crane fall; and fourthly,when the stress of the lifting hooks of the second crane is zero, connection between the lifting hooks of the second crane and the turning auxiliary hooks is relieved, the lifting hooks of the secondcrane are connected with the translation main hooks and rise, and turning of the P-type block is achieved. According to the method, by reasonably arranging lifting rings, direct contact between the lifting rings and a stainless steel material is avoided, and it is guaranteed that the performance of duplex stainless steel is not influenced.

Description

technical field [0001] The invention belongs to the technical field of shipbuilding, in particular to a method for turning over a P-type general section of duplex stainless steel. Background technique [0002] The cargo tanks of modern chemical tankers are made of duplex stainless steel, which has high strength and good corrosion resistance. At the same time, the protection of stainless steel materials is also particularly important. Not only can they not be in contact with carbon steel materials, but also need to avoid cuts and high temperature effects. In the construction of this type of ship, the inner longitudinal wall of the side section, the deck section deck, and the section of the transverse compartment included in the P-type general section are all duplex stainless steel materials. After the P-type general section is assembled based on the side-side subsection outer plate, it needs to go through two processes of turning over at 90° and hoisting. During this process,...
