Description

Technical Field

[0001] This utility model belongs to the field of steel pipe tower welding technology, and in particular relates to an auxiliary tooling for welding flanges of steel pipe towers. Background Technology

[0002] A steel pipe tower is a type of power transmission tower with steel pipes as its main components. It is widely used in high-voltage, ultra-high-voltage, and extra-high-voltage transmission lines. A steel pipe tower is mainly assembled by connecting multiple steel pipes together. Flanges are required during assembly and need to be welded and fixed to the steel pipe tower. Auxiliary tooling is required when welding the flanges to the steel pipe tower.

[0003] Chinese patent CN212977264U discloses a flange welding positioning device for steel pipe towers. The device includes a base with a movable chamber inside. A first bearing is mounted on the surface of the base, and a first rotating shaft is mounted inside the first bearing. This invention, by incorporating a turntable, a first rotating shaft, a second rotating shaft, and a threaded column, allows adjustment of the height of the first movable plate carrying the flange. Rotating the turntable drives the first rotating shaft, which in turn drives the drive wheel. The interaction between the drive wheel and the driven wheel drives the second rotating shaft, which in turn drives the threaded column. The interaction between the threaded column and the threaded pipe allows for adjustment of the height of the first movable plate, making height adjustment quicker and improving work efficiency.

[0004] However, the above scheme is inconvenient to use. It is not convenient to automatically position the flange and the steel pipe tower when fixing. The positioning operation is more troublesome. At the same time, it is not convenient to protect the steel pipe tower, making the steel pipe tower prone to friction and wear between the steel pipe tower and the tooling. Utility Model Content

[0017] Beneficial effects:

[0018] 1. First, the flanges to be welded are placed on the outside of multiple movable frames. Then, the fixed cylinder is inserted into the inside of one end of the steel pipe tower. By driving the screw to rotate, the movable block is threadedly connected to the screw, allowing the screw to rotate in different directions to move the movable block left and right. By moving the movable block to the left, one end of the movable rod moves to the left simultaneously, causing the other end of the movable rod to push the movable frame outward. The movable frame is supported by two support rods, ensuring that it remains parallel to the fixed cylinder during movement. By moving multiple movable frames outward, they all come into contact with the inner wall of the steel pipe tower, aligning the flanges with the steel pipe tower. Automatic alignment is achieved when supporting the flanges and the steel pipe tower. By moving the movable frames outward to different positions, flanges of different diameters of steel pipe towers can be supported, facilitating welding of flanges of different diameters.

[0019] 2. By moving multiple movable frames outwards, the belt can contact the inner wall of the steel pipe tower. Then, the fixed cylinder is pushed to move inwards along the steel pipe tower, simultaneously moving the movable frames. The belt is supported by support rollers, allowing it to rotate and roll against the inner wall of the steel pipe tower, preventing friction and wear caused by the movable frames. The flange is limited and supported by a limit rod, allowing the movable frames to move synchronously with the flange, bringing the flange into contact with one end of the steel pipe tower. Then, the movable frames are moved outwards again, causing the steel pipe tower to push the belt to retract to the inside of the movable frames. This allows the outer side of the movable frames to contact and support the inner wall of the steel pipe tower, providing support and fixation between the flange and the steel pipe tower, facilitating welding and fixing between the steel pipe tower and the flange.

[0028] Example 1

[0029] A preferred embodiment of the auxiliary tooling for welding steel pipe tower flanges provided by this utility model is as follows: Figures 1 to 5As shown: A welding auxiliary fixture for steel pipe tower flanges includes a fixed frame 1; a fixed cylinder 2 is fixedly installed on one side of the fixed frame 1; multiple movable frames 4 are movably connected to the periphery of the fixed cylinder 2; each movable frame 4 is movably connected to the fixed cylinder 2 via two support rods 3; a support cylinder 10 is fixedly installed on one side of the fixed frame 1, and the support cylinder 10 is located inside the fixed cylinder 2; a movable block 15 is slidably installed on the inner side of the support cylinder 10; multiple movable rods 13 are movably connected to the periphery of the movable block 15, and each movable rod 13 extends outwards... The support cylinder 10 and the fixed cylinder 2 are connected. One end of each movable rod 13 is movably installed on the inner side of a movable frame 4.
