The powder transport vehicle is a whole vehicle formed by connecting a tank body and an automobile chassis. The tank body is a main body part of the powder transport vehicle, and the tank body assembly comprises a tank body and a gasification chamber. In view of the safety of the transport tanker when driving fast or turning, the centre of gravity of the tank on the transport vehicle is usually lowered as low as possible, so that the radius of curvature of the lower part of the tank of the powder transport vehicle currently used is larger than that of the upper part. When the tank body is manufactured, an assembling mode is generally adopted, namely the tank body is separated into two half tank bodies from the middle position, and the two half tank bodies are respectively separated into a tank shell front cone and a tank shell middle cone and then are assembled and welded to form the half tank bodies. When the shell front cone and the shell middle cone are assembled, the shell middle cone is usually erected on the ground, and then the shell front cone is hoisted to the shell middle cone by a crane or a travelling crane to be lofted, assembled and welded. But the welding stress is applied to deformation, so that the deviation of the axes of the front cone and the middle cone of the tank shell is too large, the product quality is influenced, or wrinkles are generated at the last part of welding, the wrinkles must be processed, the manufacturing progress is influenced, and even the two parts are staggered too much, so that the distortion is caused, the reworking is required, and the labor and the time are wasted. In order to improve the processing quality and the processing efficiency of the tank body, supports are usually arranged in a front cone and a middle cone of the tank shell before welding, so that deformation generated in welding is reduced as much as possible.
