Road and bridge construction protection device

Abstract

This utility model discloses a road and bridge construction protection device, relating to the field of construction protection. Multiple rollers A are installed on the inner wall of the support frame, and two electric telescopic rods A are also installed on the inner wall of the support frame. Rollers B are installed at the output ends of the electric telescopic rods A. A support frame is bolted to the left side of the support frame, and two threaded rods are threadedly connected internally to the support frame. One end of each threaded rod is connected to an adjustment knob, and the other end is connected to a fixing pad. This utility model uses the electric telescopic rods A to drive the rollers B to form a clamping structure with the rollers A, which can adapt to bridge railings or temporary support beams of different diameters, achieving width adjustment and solving the problem of repeated manual adjustments required by traditional devices. The rollers B and A allow for horizontal movement of the entire device. Adjusting the knob to contact the fixing pad with the bridge railing temporarily fixes the device, preventing it from moving due to stress during construction.
