Pushing device applied to steel box girder and bidirectional pushing construction method thereof
The invention relates to a pushing device applied to a steel box girder and a bidirectional pushing construction method of the pushing device, and relates to the technical field of road and bridge construction.The pushing device comprises a base, a sliding seat, a pushing assembly, a resistance reduction connecting mechanism and a driving assembly, and the resistance reduction connecting mechanism comprises a connecting block, an inner resistance reduction wheel and an outer resistance reduction wheel; the connecting block and the outer drag reduction wheel are both fixedly connected to the sliding seat, the inner drag reduction wheel is installed on the connecting block, a connecting groove is formed in the base, the connecting block and the inner drag reduction wheel are inserted into the connecting groove, the inner drag reduction wheel abuts against the groove wall of the connecting groove, the outer drag reduction wheel is located between the base and the sliding seat, and the outer drag reduction wheel abuts against the base. The driving assembly is fixedly connected to the sliding base, a motor shaft of the driving motor is fixedly connected with the driving gear, the braking piece is installed on the sliding base and connected with the driving gear in a clamped mode, and the pushing assembly is installed on the sliding base. The steel box girder can be moved in two directions, obstruction of friction force to the moving seat can be reduced, the pushing efficiency is improved, and manual interference is reduced.
