Abstract
The invention discloses a lifting supporting device, which comprises platforms and bases. The platform consists of channel steel, nuts and lead screws. The lead screws which screw in the nuts are connected with the centers of the bottom surfaces of the channel steel. The structure of each base is a frame. A flat plate with a central through hole is connected with the top end of the frame. The lead screws of the platforms stretch into the central through holes of the flat plates at the top ends of the bases. A device for reducing friction resistance is arranged at the bottom of the frame of each base. The lifting supporting device is suitable for the construction of the subgrade of tracks which transversely penetrate through a box culvert. Firstly, an I-shaped beam is used for supporting a rail and then the device is supported between the I-shaped steel beam and the box culvert. Since columnar rollers or bearing cars are arranged between the lower surface of the device and the box culvert and can be replaced by solid lubricating materials such as polytetrafluoroethylene, graphite and the like, the friction resistance of the box culvert during jacking is reduced, the construction efficiency is improved, the labor intensity is reduced and trains can be ensured to pass safety during construction.
