Abstract

The invention discloses a complete machine in-situ swivel device of a bridge girder erection machine, which comprises a first carrier loader, a second carrier loader, a first bridge girder erection machine carrying frame and a second bridge girder erection machine carrying frame, the first bridge girder erection machine carrying frame comprises a fixed part, a connecting part and a rotating part;the connecting part is arranged between the fixed part and the rotating part and used for supporting and rotationally connecting the rotating part to the upper portion of the fixed part, the upper endof the connecting part is fixedly connected with the rotating part, and the rotating part can rotate around the central axis of the connecting part relative to the fixed part. The second bridge girder erection machine carrying frame is mounted on the second carrying vehicle and used for carrying one end of the bridge girder erection machine, so that the bridge girder erection machine rotates around the central axis of the connecting part under the support of the first bridge girder erection machine carrying frame and the carrying of the second bridge girder erection machine carrying frame. During steering, the whole bridge girder erection machine rotates, disassembly and reassembly are not needed, the labor intensity of field staff is relieved, and the cost for renting hoisting equipmentis saved.

Description

technical field [0001] The invention relates to the technical field of bridge erection construction, in particular to an in-situ rotating head device and a rotating head method of a complete bridge erecting machine. Background technique [0002] Because the JQL185 bridge erection machine can replace the traditional "track change method" laying operation, it realizes the purpose of laying the seamless line at one time, reduces the construction cost and improves the construction efficiency. Over the past few years, it has been more and more popular among paving construction units and construction units. [0003] However, due to its structural characteristics, the bridge can only be bridged forward in one direction. When encountering the construction of seamless line laying with many points and long lines, it is necessary to constantly turn around. There are two more primitive methods: 1. Disassemble into parts, turn them one by one, and then assemble them one by one; it take...
