Problems solved by technology

[0005] (1) It is difficult to effectively control the accuracy of assembly and manufacturing. For example, using manual or semi-automatic spreaders to stack glued plywood or polyurethane foam boards layer by layer, it is inevitable that there will be misalignment between layers. Once misalignment occurs, Most of them are corrected by hand or with the help of simple molds, and the production efficiency is low
[0006] (2) Manual assembly of wooden splints, poor quality stability
For the NO.96L03/L03+ series insulation box, the four sides of the special wooden plywood (Cleat) need to be connected with polyurethane and plywood by gluing. The

Embodiment 1

[0036]L03, L03+ and other types of reinforced polyurethane insulation boxes are composed of multiple polyurethane boards, plywood and wooden splints and other components that are glued and assembled; this embodiment overcomes the shortcomings of the prior art in the assembly quality control method, and designs a The control system and method for the box assembly accuracy of LNG-enhanced polyurethane standard insulation boxes in the form of L03, L03+, etc., which are suitable for multi-type L03, L03+, etc., take advantage of the high efficiency of automation equipment, and the key points for glued plywood, polyurethane board and wooden plywood, etc. The final assembly dimensional accuracy of the part and the reliability of the glued joint are overall corrected.

[0037] The part of the insulating box assembled in the previous process is sent into the assembly system by the material conveying mechanism, and then the corrected insulating box is sent out by the material conveying m...

Embodiment 2

[0139] Such as figure 1 As shown, the L03 type insulation box includes the bottom plywood 5, the bottom polyurethane board 6, the middle plywood 7, the top polyurethane board 8, the top plywood 9 and four layers respectively arranged on the bottom polyurethane board 6. Wood splint 10 at four corners.

[0140] Such as figure 2 As shown, the L03+ type insulating box includes a bottom plywood 5, a bottom polyurethane board 6, a top plywood 9 and four wooden splints 10 respectively arranged at the four corners of the bottom polyurethane board 6, which are laminated together from bottom to top.

[0141] Such as image 3 The box assembly system of the polyurethane insulation box for LNG ships shown includes a base 1 and an X-direction positioning correction mechanism 2 , a Y-direction positioning correction mechanism 3 , and a wooden splint correction mechanism 4 respectively arranged on the base 1 . A pair of X-direction positioning correction mechanisms are arranged along the ...

Abstract

The invention relates to a box body assembling system and method of a polyurethane insulation box for liquefied natural gas (LNG) ships. The box body assembling system of the polyurethane insulation box for liquefied natural gas (LNG) ships comprises a base, an X-direction positioning and correcting mechanism, a Y-direction positioning and correcting mechanism and a wood clamping-plate correctingmechanism, wherein the X-direction positioning and correcting mechanism, the Y-direction positioning and correcting mechanism and the wood clamping-plate correcting mechanism are separately arranged on the base. During assembling, the X-direction positioning and correcting mechanism and the Y-direction positioning and correcting mechanism are used for positioning and correcting the X-direction andY-direction of the polyurethane insulation box, and a wood clamping-plate is tightly pressed by the wood clamping-plate correcting mechanism. Compared with the prior art, the box assembling precisionof a plurality of modes of NO.96L03/L03+ series enhanced polyurethane standard insulation boxes can be controlled, the assembling precision requirements under different production conditions can be met, the operation is simple and convenient, and good product quality consistency is achieved.

Description

technical field [0001] The invention belongs to the technical field of liquefied natural gas ships, and relates to a box body assembly system and method for polyurethane insulating boxes used in LNG ships. Background technique [0002] The insulation box is an important part to ensure that the liquid cargo tank in the liquid cargo containment system of a large liquefied natural gas (LNG) ship is at an ultra-low temperature of -163°C. The reinforced polyurethane standard insulation box is made of rigid polyurethane foam board It is assembled and pressed together with plywood and other components. It is the core component of the membrane-type LNG ship containment system. In the NO.96 containment system, reinforced polyurethane standard insulation boxes include L03, L03+ and other forms, and a film-type LNG ship with NO.96 containment system needs 20,000 NO.96L03+ series reinforced polyurethane standard insulation boxes; The reinforced polyurethane standard insulation box has ...
