Description

Technical Field

[0001] The utility model relates to the technical field of bridge erection machines, in particular to an adjustable bridge erection machine suitable for ramp bridges. Background Art

[0002] A highway ramp bridge is a connecting section to or from a main highway, and can be either a level crossing ramp or an interchange ramp. A bridge-erecting machine is the equipment that places prefabricated beams onto prefabricated bridge piers. A bridge-erecting machine falls under the category of cranes, as its primary function is to lift beams, transport them to their location, and then lower them. A bridge-erecting machine differs significantly from a typical crane. It operates under stringent conditions and can move vertically over the beams. Several types of bridge-erecting machines are used for highway bridges, conventional railway bridges, and passenger-dedicated railway bridges.

[0003] In the prior art, when a ramp bridge is in use, the bridge erection machine is usually placed on the ramp bridge to transport and erect the beams. However, the existing ramp bridge erection machine is unable to perform rapid steering adjustments. Since the ramp usually has a small turning radius, and the bridge erection machine is difficult to turn smoothly in a narrow space, it is unable to adapt to the curve of the ramp, which in turn affects work efficiency and makes it difficult to meet actual usage needs.
