After the above items are completed, the 1 st ring of tank plates 45 are jacked up by using special jacking equipment, the 2 nd ring of tank plates 43 are surrounded under the special jacking equipment, then the 1 st ring of tank plates 45 are dropped on the 2 nd ring of tank plates 43 and are butted with the 2 nd ring of tank plates, and then the vertical welding seams and the transverse welding seams of the 2 nd ring of tank plates 43 are welded by using an automatic welding vehicle. According to the method, the welding of the 3 rd circle of tank plates … …, the n-1 th circle of tank plates 41 and the n-th circle of tank plates 39 is sequentially completed in sequence.

1. Automatic welding of vertical weld of tank plate

When the tank plate needs to be welded with the vertical welding seam, firstly, the automatic welding vehicle for the vertical welding seam of the suspension type flip-chip tank shown in figure 5 is ridden and hung on the tank body. According to the figure 4, the driving road wheels 25 and the driven road wheels 7 on the riding trailer ride on the upper edge of the tank plate 45 of the 1 st circle, and under the action of the gravity of the riding trailer and the operation vehicle, the

top wheels

8 and 24 automatically push against the outer side surfaces of the tank plates 45 of the first circle close to the upper part. At the same time the vehicle is suspended outside the tank wall by means of the

wire ropes

9 and 23. The double-drum winch on the riding vehicle can work by controlling the three-position wrench handle switch 36 on the electric cabinet 18, the operating vehicle can be lifted to the height position required by welding the vertical welding seam by adjusting the lengths of the steel wire rope 9 and the steel wire rope 23, the operating vehicle is horizontally adjusted by the operating vehicle horizontal adjusting device, and then the three-position wrench handle switch 33 on the electric cabinet 18 is controlled to enable the riding vehicle and the operating vehicle to transversely walk to the position of the vertical welding seam to be welded. The telescopic top wheel 14 and the telescopic top wheel 20 are adjusted and retracted, so that the magnetic wheel 12 and the magnetic wheel 21 on the upper part of the operating vehicle are attracted to the steel plate of the tank wall, and the lower part of the operating vehicle is supported on the steel plate of the tank wall by the lower top wheel 16 and the lower top wheel 17. The welding rail 64 and the parallel vertical welding seam of the welding trolley 61 are attracted to the right side of the vertical welding seam of the steel plate on the tank wall by means of two magnet bases 57 and four magnets 56. After various preparations before welding are made, the vertical welding seam can be automatically welded. After the vertical weld is welded, the welding rail 64 is removed, and the trailer and the operating vehicle are moved to the next vertical weld to perform the same welding operation. And repeating the steps until all vertical welding seams of the circle of the tank wall steel plate are welded. And for the welding of the vertical welding seam of the newly added ring of tank plate, the whole process of the last ring of welding operation can be referred to.

2. Automatic welding of transverse weld of tank plate

When the tank plate is to be subjected to transverse welding seam automatic welding, a suspension type inverted tank transverse welding seam submerged arc automatic welding vehicle shown in figure 6 is placed on the tank wall steel plate in a mode shown in figure 4. The three-position handle-pulling switch 36 on the electric cabinet 18 is operated to enable the double-drum winch on the trailer to work, the length of the steel wire rope 9 and the steel wire rope 23 is adjusted, the roller 70 and the roller 76 on the pallet frame 68 of the operation vehicle and the supporting belt 74 are adjusted to be about 30 mm below a transverse welding line to be welded, the operation vehicle is horizontally adjusted through the horizontal adjusting device of the operation vehicle, the telescopic top wheel 14 and the telescopic top wheel 20 are retracted, and the magnetic wheel 12 and the magnetic wheel 21 are attracted to a steel plate on the wall of the tank. The lower top wheel 16 and the lower top wheel 17 are retreated, so that the front end surfaces of the

rollers

70 and 76 on the tray frame 68 are pressed against the steel plate of the tank wall. Because the front end faces of the roller 70 and the roller 76 are inclined by 10 degrees with the tank wall steel plate, only the upper edges of the front end faces of the two rollers are in contact with the tank wall steel plate, when the operation vehicle travels, the roller 70 and the roller 76 roll on the tank wall steel plate, and simultaneously, the supporting belt 74 is driven to be tightly attached to the tank wall steel plate to rotate. And finely adjusting the lifting adjusting mechanism 73 to enable the supporting belt 74 to be located at a proper position below the n-1 th circle of transverse welding line 40. By means of the suspension of the steel wire rope 9 and the steel wire rope 23 on the trailer, the suction force of the

magnetic wheels

12 and 21, the gravity of the operating vehicle and the support of the

rollers

70 and 76, the operating vehicle can stably attach to the steel plate on the wall of the tank and can transversely walk on the steel plate.

After the working position and the state of the operation vehicle are adjusted, other preparations before welding are completed, and then the submerged-arc automatic welding can be carried out on the n-1 th circle of transverse welding seam 40 through the welding control box 82. The subsequent welding of the transverse welding seam of the steel plate of the added tank wall can be finished by referring to the whole process of the welding operation of the transverse welding seam.

When the suspension type automatic welding vehicle for the flip-chip can is used and needs to be lifted away from the can body, the telescopic top wheel 14 and the telescopic top wheel 20 are firstly adjusted to extend outwards, so that the magnetic wheels 12 and the magnetic wheels 21 are separated from the steel plate on the can wall, and then the whole vehicle is lifted and separated from the can body through the lifting lugs 5 and the lifting lugs 27.

3. CO2 gas shielded welding

In the automatic welding vehicle for vertical welding seams of the suspended type inverted can shown in fig. 5, if the water-cooling welding torch 60 is replaced by a common CO2 gas shielded welding torch, and the vehicle is slightly adjusted, the vertical welding seams and the transverse welding seams of the inverted can be welded by using a CO2 gas shielded welding method.
