Capsule bogie lifting device for caisson transportation
The invention relates to a capsule bogie lifting device for caisson transportation. Track rubber pads are laid between steel rails and steel pads of the lifting device generally, steel strips are inlaid in the positions where the upper surfaces of the track rubber pads and the steel rails are contacted, wheel pressure of frame wheel rails on the base can be uniformly distributed, the flatness between each steel rail and a corresponding support plane is adjusted, so that the track rubber pads have rigid and elastic dual-bending-loading characteristics, the abrasion resistance of the track rubber pads is enhanced, and the steel rails cannot generate overhigh internal stress; the lifting device is provided with multi-cylinder force-adjusting rubber pads for adjusting pressure difference between the bottom surface of each caisson and the bottom surface of a cover plate contacted with the top surface of each bogie, the pressure difference of each bogie is reduced, and safe caisson transportation is guaranteed; internal reinforcing ribs and external reinforcing ribs are arranged in the multi-cylinder force-adjusting rubber pads, the elasticity of the multi-cylinder force-adjusting rubber pads is improved accordingly, the amount of compression of the multi-cylinder force-adjusting rubber pads is reduced under the ultimate pressure value, and the service life of each multi-cylinder force-adjusting rubber pad is prolonged.
