Background

The capacity of the traction transformer for the vehicle is 580-11000 kVA, so the weight of the body of the traction transformer is greatly different due to the large difference of the body size of the traction transformer. The vehicle traction transformer is different from other transformers in that the vehicle traction transformer body is horizontally placed, and other transformers are vertically placed. Because the capacities of the transformers are different and the sizes of the clamping pieces are different, the diameters of the used horizontal transformer body placing devices are different; the height difference of the horizontal support surfaces of the upper clamp piece end and the lower clamp piece end of each vehicle type is different; when a new vehicle different from the former vehicle type appears, a special lying device needs to be designed. The diameter of the existing horizontal placing foot pad for the body of the large-capacity transformer is larger than the width of the clamping piece, so that the horizontal placing foot pad cannot be used for the horizontal placing of the body of the small-capacity transformer; the lying foot pad for the small-capacity transformer body has a small diameter, bears limited load and cannot be used for lying the large-capacity transformer body, so that the lying foot pad for the small-capacity transformer body cannot be used for lying the large-capacity transformer body. Therefore, the body horizontal placing device is mostly a special device, a plurality of body horizontal placing devices are stored on site due to a plurality of vehicle types, a large amount of operation fields are occupied, a new horizontal placing device needs to be purchased when a new vehicle type is produced, and the manufacturing cost is increased. At present, the device for horizontally placing the body of the transformer is a special tool, and various tools are placed on the site to occupy a large amount of operation sites. The frock is changed again when the motorcycle type changes, because the frock is heavier, changes and consumes a large amount of physical stamina. When a new vehicle is trial-manufactured, a new tool needs to be purchased, and the trial-manufacturing cost of the new product is increased. Therefore, the transformer horizontal universal device which can flexibly adapt to the horizontal height of the transformer and the outer diameter of the support has important significance in the field.
