A number of upper rim steel plates are welded around the upper tank rim, and a number of lower rim steel plates are welded around the lower tank rim. The number of upper rim steel plates and lower rim steel plates is the same and they correspond to each other one by one. A positioning hole one and a positioning hole two that are matched with the positioning column are respectively formed on each upper rim steel plate and each lower rim steel plate. The positions of the positioning hole one on the corresponding upper rim steel plate and the positioning hole two on the lower rim steel plate are matched. The positioning column passes through the positioning hole one and the positioning hole two, and welds the lower tank rim and the upper tank rim together. One end of the positioning column is a conical structure, and the conical structure is located below the lower rim steel plate.
[0006] Both the upper rim steel plate and the lower rim steel plate are rectangular steel plates.
[0007] The length of the upper rim steel plate is greater than the length of the lower rim steel plate.
[0008] Both the positioning hole one and the positioning hole two are round holes. The distance from the center of the positioning hole one to both sides of the upper rim steel plate is the same, and the distance from the center of the positioning hole two to both sides of the lower rim steel plate is the same.
[0009] Both the upper rim steel plate and the lower rim steel plate are fourteen pieces.
[0010] The beneficial effect of the utility model is: simple in structure, easy to implement, and remarkable in effect. It can effectively achieve precise alignment by welding special steel plates on the tank rim and using a positioning column with a conical structure at the end, thereby improving the accuracy and efficiency of welding.
