AI Technical Summary
During the production process of steel bridge decks, when the U-rib bridge top plate flips, due to design requirements, the lifting lugs cannot be installed, resulting in the use of hooks to directly hook the steel plate, which can easily cause scratches to the steel plate.
A flap workpiece with U-rib bridge top plate is designed, including sliding plate, suspending ring, adjustment mechanism and clamping mechanism. The position of the clamping plate is manually adjusted through the adjustment mechanism, which corresponds to the holes of the U-rib. The tooling is bolted to the bridge top plate by fixing bolts and nuts to achieve flip plates and prevent scratches.
The safe flip of the bridge top plate is achieved, which avoids scratches on the steel plate, facilitates subsequent welding treatment, and improves construction efficiency.
