Embodiment Construction

[0033] The technical solutions in this application will be further described in detail below in conjunction with the accompanying drawings.

[0034] The embodiment of the present application discloses an inverted tire frame for steel box girder welding. Please refer to figure 1 , an overturn tire frame for steel box girder welding includes a base 11 . Two ends of the base 11 are fixedly provided with brackets 12 , and a workbench 2 is rotatably arranged between the two brackets 12 . Place the steel box girder on the workbench 2, and then weld the steel box girder by the staff. The workbench 2 has a semi-cylindrical structure, and an arc-shaped rack 31 is fixedly arranged on the circumferential surface of the workbench 2 . A gear 32 is rotatably arranged on the base 11 , and the gear 32 meshes with the arc-shaped rack 31 . The base 11 is provided with a power assembly for driving the gear 32 to rotate. The power assembly drives the gear 32 to rotate. The gear 32 can drive t...

Description

technical field [0001] The present application relates to the technical field of steel structure processing equipment, in particular to a flip tire frame for steel box girder welding. Background technique [0002] Box girder is a kind of beam in bridge engineering. It is hollow inside and has flanges on both sides of the upper part, which is similar to a box, hence the name. Common box girders are divided into materials, and there are two main types, one is prestressed reinforced concrete box girder, and the other is steel box girder. Among them, prestressed reinforced concrete box girders are constructed on site, and in addition to longitudinal prestress, some also have transverse prestress. Among them, steel box girder, also known as steel plate box girder, is a commonly used structural form of long-span bridges, and is used on bridges with large spans. Steel box girders are generally processed in the factory and then transported to the site for installation. There are a...
