AI Technical Summary
Traditional steel box girder installation supports have fixed support height and position, which cannot adapt to changes in the height and position of the steel box girder, resulting in reduced support effectiveness.
The system employs a drive assembly and an adjustment assembly. A drive motor rotates the drive rod and drive bevel gear, which in turn drives the bidirectional screw and scissor fork to move the mounting plate. An adjustment motor rotates the adjustment worm and adjustment worm wheel, which in turn moves the adjustment screw and slider to move the adjustment plate, thus enabling flexible adjustment of the height and position of the steel box girder material.
It enables flexible adjustment of the height and position of the steel box girder material, improving the effectiveness and adaptability of the support system.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge construction technology, and in particular to a steel box girder installation bracket. Background Technology
[0002] Steel box girders, also known as steel plate box girders, are a common structural form for long-span bridges, mostly used on bridges with large spans. They are called steel box girders because their shape resembles a box. The main components of the steel box girder installation support include steel pipe columns, strip foundations, temporary support systems, and temporary crash barriers. These components are temporarily connected to the steel crossbeams on both sides of the steel pipe columns through crossbeam connectors, and then hoisted to the top of the steel pipe columns and secured. The erection of the steel box girder is assisted by three-way jacks and adjusting supports. Traditional temporary supports usually have the support arms welded and fixed to the bottom beam, resulting in a fixed support height and position. This makes it impossible to adapt to changes in the height and position of the steel box girder, requiring the support to be disassembled and reassembled, thus reducing its effectiveness. Utility Model Content
