Abstract
The invention relates to a capsule trolley jacking device. The jacking device is provided with a multi-column force adjustment rubber base plate. The pressure differences between the bottom surfaces of cover plates, making contact with the top surfaces of trolleys, on the bottom surfaces of sink boxes are adjusted so that the pressure differences between the trolleys can be adjusted. The multi-column force adjustment rubber base plate is provided with inner reinforcing ribs and outer reinforcing ribs, so that the elasticity of the multi-column force adjustment rubber base plate is improved, and the service life of the multi-column force adjustment rubber base plate is greatly prolonged. A rubber rail base plate is laid between a steel rail of the jacking device and a steel base plate in the whole length direction. Steel strips are embedded in the position where the upper surface of the rubber rail base plate makes contact with the steel rail and can be used for evenly distributing the wheel pressure of a frame wheel track on the base portion and adjusting the flatness between the steel rail and the supporting surface. Grooves consistent with the extension direction of the steel rail are formed in the upper surfaces of the steel strips so that the rubber rail base plate has both the rigid bending-load bearing characteristic and the elastic bending-load bearing characteristic, the abrasion resistance of the rubber rail base plate is improved through the two bending-load bearing characteristics, and it is ensured that too high internal stress cannot be generated by the steel rail.
