Automatic welding system for corrugated membrane sheet of membrane type liquefied-gas cargo hold, structure for guiding and fixing automatic welding apparatus for corrugated membrane sheet of membrane type liquefied-gas cargo hold, and structure for guiding automatic welding apparatus for corrugated membrane sheet of membrane type liquefied-gas cargo hold

Abstract

The present invention relates to an automatic welding system for a corrugated membrane sheet of a membrane type liquefied-gas cargo hold, a structure for guiding and fixing an automatic welding apparatus for a corrugated membrane sheet of a membrane type liquefied-gas cargo hold, and a structure for guiding an automatic welding apparatus for a corrugated membrane sheet of a membrane type liquefied-gas cargo hold. When a corrugated membrane sheet is welded, a cross-anchor strip having a fixing groove is installed on a portion where longitudinal and lateral anchor strips, which are attached to the upper surface of a heat insulating panel on which the corrugated membrane sheet is mounted, cross each other, which makes it possible to install a welding guide that supports the automatic weldingapparatus and guides a movement of the automatic welding apparatus using the fixing groove, thereby stably performing automatic welding on the corrugated membrane sheet.

Description

technical field [0001] The present invention relates to a corrugated diaphragm automatic welding system for membrane-type liquefied gas cargo tanks, and more specifically to a corrugated diaphragm automatic welding system for membrane-type liquefied gas cargo tanks, a method for guiding and fastening membrane-type liquefied gas The structure of the automatic welding device for the corrugated diaphragm of the gas cargo tank, and the structure of the automatic welding device for the corrugated diaphragm used to guide the membrane-type liquefied gas cargo tank, the automatic welding system for the corrugated diaphragm of the membrane-type liquefied gas cargo tank includes a tight Cross-anchoring strips for fixed grooves, wherein the cross-anchoring strips are provided at the junction between the longitudinal and transverse anchoring strips attached to the upper surface of the insulating plate on which the corrugated diaphragm to be welded is placed , so that the welding guide for...

Problems solved by technology

[0032] However, typical structures for fastening automatic welding machines are difficult to stably support automatic welding machines during automatic welding of corrugated diaphragms

Especially, during the welding of the upper surface and the side surface of the warehouse, it is more difficult to support the automatic welding machine with such a typical fastening structure due to the weight of the automatic welding machine, thereby deteriorating workability and stability
