Description

Technical Field

[0001] The utility model relates to the field of supporting equipment, in particular to a supporting bracket used for bridge construction. Background Art

[0002] Bridges are highway routes that cross rivers, harbors, lakes, reservoirs, irrigation canals and other water bodies, or cross deep valleys with large elevation differences, or cross passages of other traffic routes. In order to keep traffic flowing, bridges need to be built. Busy urban areas sometimes need to have elevated roads consisting of viaducts. Support brackets are often used in bridge construction and maintenance operations. Therefore, construction support brackets used for elevated bridges are an important building support device.

The positioning mechanisms include a baffle, multiple hydraulic cylinders and multiple positioning plates. One side of the top of the support plate is fixedly connected to the bottom of the baffle, one side of the multiple hydraulic cylinders is fixedly connected to one side of the baffle, and the output ends of the multiple hydraulic cylinders are respectively fixedly connected to one side of the multiple positioning plates. By starting the multiple hydraulic cylinders, the output ends of the multiple hydraulic cylinders respectively push the multiple baffles to clamp and fix the two sides of the bridge to avoid lateral displacement of the bridge. However, the two sides of the bridge are generally inclined, and the degree of inclination of the two sides of different bridges is different. Since the positioning plate is fixedly connected to the output end of the hydraulic cylinder, the angle of the positioning plate cannot be adjusted according to the degree of inclination of the inclined surfaces on both sides of the bridge, so that the contact area between the positioning plate and the two sides of the bridge is reduced, and the clamping stability is low.
