Embodiment Construction

[0020] refer to Figure 1 to Figure 3 , the present invention is a kind of positioning method of tank body, and it comprises the following steps:

[0021] S1: Equally measure the radius data of the outside of the wooden block structure 20 of the tank body 10;

[0022] S2: Equally measure the radius data of the structural groove 40, the structural groove 40 is assembled on the hull structure 30, and the measurement position of the structural groove 40 is consistent with the measurement position of the wooden block structure 20;

[0023] S3: Comparatively analyze the radius data of the wooden block structure 20 and the radius data of the structural groove 40, adjust the structural groove 40 according to the radius data of the wooden block structure 20, ensure the clearance requirements between the wooden block structure 20 and the structural groove 40, and control the over-tolerance The position of the structural groove 40 is rectified, and then the structural groove 40 is weld...

Abstract

The invention discloses a positioning method of a tank body. According to the method, the measurement data of a wood block structure and a structural groove are matched and adjusted, the structural groove on a hull structure is arranged according to the installation data of the wood block structure, a 45-degree positioning line of the tank body and a 45-degree positioning line of the hull structure are drawn and matched so that the tank body can be quickly and accurately positioned on the hull structure, the positioning precision requirement is met, the positioning time is shortened, and the situation that the tank body is damaged due to the fact that the wood block structure collides with the hull structure is avoided. The method is used in the technical field of ship construction.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a tank body positioning method. Background technique [0002] There are three vertical LNG tanks in the middle of the cargo hold of the 1400TEU dual-fuel container ship undertaken by our factory. The wooden block structure of the pipe body and the hull structure are an embedded connection method. Epoxy is injected into the embedded groove, and the tank body is close to the ring. Oxygen is fixed to the hull structure. Due to the high positioning accuracy requirements of LNG tanks, and the production of tanks is relatively expensive, the damage caused during the positioning process is irreversible, and in severe cases, LNG tanks will be remade. In order to solve this problem, we invented a tank positioning method, precise positioning, one-time success, complete the positioning of the tank, eliminate rework, and shorten the ship construction cycle. Contents of the invention ...
