Description

TECHNICAL FIELD

The bridge steel structure support frame comprises a mobile lifting mechanism and a folding support mechanism. Under the action of the mobile lifting mechanism, when the two groups of storage columns and the telescopic rods move, the folding support mechanism can be unfolded or folded. That is, under the action of the hinge rod, when the multiple support plates are close to each other, the hinge rod will shrink into the folding groove. At this time, it is convenient to support the bridge with smaller size. When the two groups of storage columns and the telescopic rods move away from each other, the multiple support plates can be unfolded under the action of the hinge rod. At this time, it is convenient for bridges with larger size. The top plate at the upper end of the support plate will press and support the support point, thereby facilitating the folding support mechanism to support bridges of different sizes.
