Therefore, during manufacturing, four tank walls of the oil tank are required to be welded together in a seamless mode according to the size required by the drawing through positioning and pairing. However, because the transformer oil tank is large in size and heavy in weight (the length is 5-12m, the width is 2-4m, and the weight is 1-4 tons), the zero gap and the zero deviation of the assembly time between the tank walls are realized, 2-3 persons are required to cooperate under the cooperation of the aerocar, the lead screw is firstly welded and supported, then the lead screw is used for adjustment, and because the stroke of the lead screw is limited, the inner diameter of the oil tank is often exceeded or cannot be reached. Therefore, the distance and the gap between the walls of the box are adjusted by adjusting the stroke of the screw rod or the jack by using the jack for matching adjustment. However, because the height of the oil tank is higher, the wall of the oil tank has certain flexibility, and the weight of the jack and the screw rod is added, the screw rod and the jack are easy to fall down in the operation process, and the risk of injuring people by smashing exists; in addition, when each oil tank is processed, the purpose effect of adjustment can be achieved by matching a plurality of lead screws.

The technical scheme of the utility model is as follows:
a tool for adjusting assembly welding gaps of the tank wall of a transformer oil tank consists of a fixed seat and a rotating mechanism, wherein the fixed seat is a C-shaped clamp, and a screw hole is formed in the upper end of the C-shaped clamp; the rotating mechanism consists of a bolt, a first nut and a second nut which are welded together in a vertical mode, the bottom edge of the second nut is welded with the bolt, and the bolt, the first nut and the second nut are positioned on the same straight line; the bolt is matched with a screw hole on the C-shaped clamp.
The first nut and the second nut are hexagonal nuts, and the bottom edge of the first nut and the top edge of the second nut are welded together.
The bottom edge of the second nut is welded with the bolt cap of the bolt.
The length of the upper end of the C-shaped clamp is greater than that of the lower end of the C-shaped clamp, and the vertical face of the lower end of the C-shaped clamp is welded on the tank wall of the transformer oil tank and is close to a gap between adjacent tank walls.
The metal rod is inserted into the first nut or the second nut to rotate the rotating mechanism, the outer diameter of the metal rod is smaller than the inner diameters of the first nut and the second nut, and the metal rod is made of round steel or square steel.
Welding the vertical surface of the lower end of the C-shaped clamp on one box wall, enabling the C-shaped clamp to span a gap, enabling the end face of the upper end of the C-shaped clamp to be parallel to the other box wall, and enabling a bolt of the rotating mechanism to be perpendicular to the other box wall; the metal rod alternately penetrates into the first nut or the second nut of the rotating mechanism, and the metal rod is rotated so that the bolt of the rotating mechanism is downwards rotated to push the box walls to move, and therefore the purpose of adjusting gaps between the box walls is achieved. The utility model can be used for assembling between the walls of the large-scale transformer tank, between the walls of the tank and the tank cover, and between the walls of the tank and the tank bottom for adjusting gaps.
The utility model has the positive effects that: the device can be used at any butt joint position of the transformer oil tank, different angles are adjusted, the requirement on the operation space is small, the operation is safe and reliable, and the risk of falling and smashing of heavy objects is reduced; the operation method is simple, convenient, time-saving and labor-saving, and the labor efficiency is greatly improved.
