Background technique

Existing bridge-building machines need to anchor the traveling beams to the existing girder deck, and the traveling beams and the main beams of the hanging basket are connected through reverse hanging wheels to prevent the hanging basket from overturning during travel. During the running process, the hanging basket needs to re-lay and anchor the traveling beams on the top surface of the poured bridge, then guide the main beam to the new walking beam, and then dismantle the old walking beam; or by connecting the walking beam and the hanging basket An additional device is installed between the main beams to realize the relative movement of the main beam and the walking beam of the hanging basket, and finally complete the walking process. However, both methods require pre-setting numerous vertical anchoring holes for traveling on the bridge. During the traveling process, it is necessary to manually dismantle and install the rail beams and anchoring steel bars of the traveling beams repeatedly.
