Light small-curve segment assembling and bridging machine
The invention provides a light small-curve segment assembling and bridging machine, belongs to the technical field of span-by-span assembling and bridging of prefabricated segments and mainly solves the problems that the operation is complex and the efficiency is lower as the permanent structure design is limited by the fact that the existing double-girder structure bridging machine is heavier in dead weight, and girders are required to be bent when a bridge with the small curve radius is erected. The light small-curve segment assembling and bridging machine is mainly characterized by comprising a girder, end suspensions, a front auxiliary supporting leg, a front middle supporting leg, a hoisting crown block, a rear middle supporting leg and a rear auxiliary supporting leg. The girder is of a single-rectangle frame truss structure; the two end suspensions are responsible for lowering of a full span box girder; the front auxiliary supporting leg and the rear auxiliary supporting leg are used for assisting the bridging machine in hole passing; the front middle supporting leg and the rear middle supporting leg are used for supporting an erection beam of the bridging machine; the bridging machine can be integrally traversed to erect the small curve and the complex line through the rotation beam and sliding beam structure of the middle supporting legs; the hoisting crown block is of an inverted structure. The light small-curve segment assembling and bridging machine has the characteristics of safety, lightness and practicality, and is mainly used for erecting small-curve radius bridges.
