[0002] A steel structure bridge is a bridge built with steel structure. Generally, such bridges use more than 50% steel in total and are called "large steel structure bridges". During the manufacturing process of steel structure bridges, auxiliary tooling is required to position the steel structure.

[0003] In the use of auxiliary tooling for existing steel structure bridge manufacturing, there is no equipment to support the existing H-shaped steel structure during the painting or spraying of anti-corrosion materials, resulting in the H-shaped steel structure being not very convenient during the manufacturing process. When installing or processing the inclined H-shaped steel structure, it is easy to cause safety hazards due to poor support. Utility Model Content

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] An auxiliary tooling for manufacturing steel structure bridges comprises a connecting seat, an extrusion platform is arranged on the upper surface of the connecting seat, first notches are opened on two opposite surfaces of the connecting seat, a hydraulic rod is arranged on one surface inside the first notch, an output end of the hydraulic rod is fixedly connected to the extrusion platform, a plurality of transmission rollers are arranged inside the extrusion platform, a servo motor is arranged on one end of one side of the extrusion platform, the fixed seat is a "U"-shaped plate structure, an output end of the servo motor is fixedly connected to the rotating shaft of the leftmost transmission roller, a second notch is arranged on one side of the connecting seat, a sliding rod is arranged in the second notch, and an extrusion mechanism is slidably connected to both sides of the peripheral side of the sliding rod, the extrusion mechanism comprises a support frame, a screw is threadedly inserted on the upper surface of the support frame, a fixed seat is fixedly connected to the lower end of the screw, a limited block is fixedly connected to one side of the fixed seat, and an extrusion wheel is arranged in the fixed seat.

[0007] Furthermore, the support frame is a "C"-shaped plate structure, the shape and size of the support frame are adapted to the second notch, and the support frame is slidably matched with the second notch.

[0008] Furthermore, a plurality of third slots are provided on the bottom surface of the connecting seat, and movable wheels are arranged inside the third slots, and the movable wheels have a self-locking function.

[0009] Furthermore, mounting plates are fixedly connected to the lower sides of both ends of the connecting seat, and positioning holes are provided on the upper surface of the mounting plates.

[0010] Furthermore, one end of the limit block abuts against a surface of the support frame, and the limit block and the support frame cooperate with each other.

[0011] The utility model has the following beneficial effects:

[0012] By placing the H-shaped steel structure between the driving roller and the extrusion wheel, and providing limited support through the driving roller and the extrusion wheel, the coating processing of the H-shaped steel structure is facilitated; and by setting a servo motor to drive the driving roller, the H-shaped steel structure can be flexibly driven to move horizontally on the driving roller according to the actual processing situation; the overall lifting and lowering of the extrusion platform can be achieved by adjusting the hydraulic rod, so as to reach a suitable height, meet the use of different processing platforms, and increase its applicability.
