Description

Technical Field

[0001] The utility model relates to the technical field of bridge erection machines, in particular to a main beam slope adjustment device for a bridge erection machine. Background Art

[0002] A bridge-erecting machine is a device that places prefabricated beams onto prefabricated bridge piers. A bridge-erecting machine belongs to the category of cranes because its main function is to lift the beams, transport them to the location, and then lower them.

[0003] A device for adjusting the slope of the main beam of a bridge erecting machine is disclosed in the Chinese utility model patent application publication specification CN202222864530.3. During the erection process, the bridge erecting machine needs to meet the requirements of the slope of the railway line. Sometimes the longitudinal slope of the railway line is very large, and the bridge erecting machine needs to adjust the slope of its main beam within a safe range to complete the beam erection work. If the slope of an existing bridge erecting machine is to be adjusted, the main beam slope is often adjusted by adjusting the heightening segment on the front vehicle of the bridge erecting machine or by adjusting the heightening segment on the outrigger. However, in order to adjust the slope by the heightening segment, the supporting effect is poor when supporting the crossbeam. Therefore, a device for adjusting the slope of the main beam of a bridge erecting machine is needed. Utility Model Content
