Description
Technical field
The utility model relates to the manufacture field of high vacuum multiple layer heat insulation LNG gas tank peculiar to vessel, specifically relates to a kind of self-powered tractor truck of high vacuum multiple layer heat insulation LNG gas tank fit technique.
Background technology
According to existing codes and standards, current LNG peculiar to vessel (Liquefied Natural Gas, liquefied natural gas) gas tank generally adopts double-layer stainless steel horizontal tank, comprise shell and inner bag, through inspection, after inner bag is qualified, inner bag is sleeved in shell, then two ends end socket is installed, the mezzanine space between shell and inner bag is closed, finally mezzanine space is vacuumized.In whole manufacturing process, fit is the link that difficulty of construction is larger, has direct impact to the quality of product.
At present, the fit technique of each LNG gas tank manufacturer peculiar to vessel generally comprises following steps: shown in Figure 1, LNG gas tank peculiar to vessel comprises shell 2, inner bag 6, existing socket unit comprises and scoops out frame 1, flat truck 4, overhead traveling crane 7, suspender belt 8, scoop out the side that frame 1 is positioned at flat truck 4, inner bag 6, overhead traveling crane 7, suspender belt 8 is positioned at the opposite side of flat truck 4, flat truck 4 is fixed with roller moulding bed 3, the shell 2 of LNG gas tank peculiar to vessel is fixed on roller moulding bed 3, pilot trolley 5 is provided with in shell 2, pilot trolley 5 in shell 2 is connected with one end of inner bag 6, overhead traveling crane 7 is sling by the other end of suspender belt 8 by inner bag 6.The wheel of pilot trolley 5 is by being fixed on the guide rail walking of shell 2 inwall, but pilot trolley 5 does not have power, can only apply horizontal drag force, delivered in shell 2 by inner bag 6 by overhead traveling crane 7 pairs of inner bags 6 and pilot trolley 5.Overhead traveling crane 7 level is to left movement, draw inner bag 6 together with pilot trolley 5 to left movement, scoop out on frame 1 until pilot trolley 5 falls within, then the center regulating inner bag 6 and shell 2 point-blank, swing roller moulding bed 3, until the circumference location completing inner bag 6 and shell 2; Overhead traveling crane 7, by side-to-side movement, has carried out the axial location of inner bag 6 and shell 2, and finally, fixing inner bag 6, completes the fit of inner bag 6 and shell 2.
