1) hangs the centralized positioning steel wire to the center in length and breadth at independent tank top, draw in length and breadth to line of centers at cabin bottom transverse, longitudinal ligament beam correspondence position;
2) after independent cargo hold enters cabin soon near carrying out the adjustment of vertical, horizontal location before the lamination wood, the independent cargo hold that continues to fall allows the centralized positioning piece on the independent tank top centralized positioning alignment of a hole cabin support stringer;
3) continue to fall to dropping to fully on the lamination wood up to independent cargo hold, measure steel wire and line relative position, deviate is controlled in the 20mm scope, otherwise need readjust;
4) location is finished the back and is welded the located lateral piece, be specially the located lateral piece is clung on the gusset of the corresponding location of independent tank top, and with located lateral piece and hold beam spot welding.
6. the localization method of asphalt tanker independence cargo hold according to claim 5 and hull, it is characterized in that described independent cargo hold horizontal location step comprises: after 1) independent cargo hold drops to and compresses on the lamination wood, the height of adjusting every adiabatic cradle makes it fully contact with independent cargo hold bottom surface, and adiabatic cradle bottom nut locks;
2) prepare the adjustment cushion block of all size in advance, when the regional adiabatic cradle height adjustment range in part is not enough, can suitably increase the adjustment cushion block, adjust the bottom that cushion block need reliably be welded to independent cargo hold after finish the location, measure the thickness of required adjustment cushion block with clearance gauge.
7. the localization method of asphalt tanker independence cargo hold according to claim 6 and hull, it is characterized in that the cast step that described second lift independence cargo hold carries out located lateral block welding and epoxy mortar comprises: 1) promote independent cargo hold once more, use special-purpose stirrup to support independent cargo hold; 2) reinforce welding located lateral piece; Adiabatic cradle bottom nut locks; Epoxy mortar is poured into adiabatic cradle rapidly to be enclosed in the frame.
8. the localization method of asphalt tanker independence cargo hold according to claim 7 and hull is characterized in that the described independent cargo hold secondary step in place that descends comprises: 1) behind the epoxy mortar all dry, and all instruments, foreign material etc. in the cleaning cabin; 2) loop wheel machine that hoists is removed and is supported stirrup, all lamination wood, with independent cargo hold fall once more the position to before the position of location, finish the location work of independent cargo hold.
