Novel bridge height limiting device for highway engineering

The invention provides a novel bridge height limiting device for highway engineering, which comprises a height limiting cross beam and supporting beams arranged at two ends of the height limiting cross beam, and further comprises a base, and a lifting adjusting device is connected between the base and the supporting beams. The lifting adjusting device comprises an upper platform connected with the lower end of the supporting beam, a lower platform connected with the upper end of the base, an electric lifting adjusting mechanism and a guide mechanism, wherein the electric lifting adjusting mechanism and the guide mechanism are movably arranged between the upper platform and the lower platform. Compared with the prior art, the height limiting device is simple in structure, the height of the height limiting cross beam can be adjusted according to needs, under the condition that an ultra-high vehicle forcibly passes and is clamped under the height limiting device, the clamping condition is relieved by adjusting t
