Highway-railway dual-purpose bridge erecting machine suitable for small-curvature-radius tunnel
The invention discloses a highway-railway dual-purpose bridge erecting machine suitable for a small-curvature-radius tunnel. The machine comprises a girder and supporting legs installed at the bottom of the girder. The girder comprises multiple sections of cross beams sequentially hinged in an end-to-end mode; the hinge portion between every two adjacent sections of cross beams is provided with a vertical pin hole and provided with a vertical pin shaft; the two sides, on the hinge portion, of one end of every two adjacent sections of cross beams are each provided with a transverse pin hole and a transverse pin shaft, and every two adjacent sections of cross beams are fixedly connected together. By means of the machine, the girder of the bridge erecting machine can be bent and adjusted under the condition that one section of bridge is erected, gets ready to pass the tunnel and accords with the curvature radius of the tunnel, and the problem that when the bridge erecting machine passes the tunnel and is moved, a large hoisting device is needed and the girder is disassembled and assembled is solved. Meanwhile, reassembly time is saved, large-scale disassembly and assembly cost is reduced, labor intensity of workers is reduced, and the bridge erecting machine is easy to manufacture, low in cost, good in adaptability, safe and reliable.
