The application discloses a railway cast-in-place
box girder hydraulic inner mold and relates to the technical field of railway cast-in-place
box girder construction. The hydraulic inner mold comprises an adjusting
assembly, the adjusting
assembly comprises an inner mold, a connecting support is arranged in the inner mold, a hydraulic oil cylinder is arranged at the top of the connecting support, a supporting beam is arranged at the top end of the hydraulic oil cylinder, connecting seats are symmetrically arranged at the two ends of the supporting beam, a fixing frame is rotatably installed through the connecting seats, and a first adjusting frame is connected to one side of the fixing frame. The adjusting
assembly is arranged to adjust the two symmetrically arranged first adjusting frames through
hydraulic pressure. When the inner mold is controlled to move in the
box girder, the inner mold can be controlled to shrink according to the moving condition through
hydraulic pressure adjustment, so that the normal movement of the inner mold is ensured, the movement interference between the inner mold and the web plate in the box girder is avoided, the problem that the existing device cannot be adjusted and is prone to movement interference during movement and cannot support movement is solved, the normal construction is ensured, and the construction efficiency is effectively improved.
