A jacking mechanism for steel tiles in inclined shafts

technical field

The utility model relates to a jacking mechanism for steel tiles in inclined shafts. The utility model is suitable for the technical field of inclined shaft construction in pumped storage power stations.

Background technique

As an important building in the pumped storage power station, the diversion inclined shaft has the characteristics of steep inclination, large diameter and long length, and the construction of the inclined shaft is extremely difficult. In the construction of the inclined shaft, in order to ensure the stability of the inner wall structure of the inclined shaft, it is necessary to assemble steel tiles on the inner wall of the inclined shaft for support to ensure the overall stability of the inner wall of the inclined shaft. Therefore, it is necessary to assemble the steel tiles with the help of an assembly machine.

At present, the steel tiles of the shield on the inner wall of the inclined shaft are usually assembled by hoisting machinery to hoist the steel tiles to the appropriate position, combined with manual assembly. Since the inner wall of the inclined shaft is a curved structure, the hoisting method cannot ensure that the steel tiles can Quickly and accurately move to the assembly position, and because the steel tiles are heavy and bulky, manual operation will bring a greater burden, and it is impossible to automatically and flexibly assemble the steel tiles.
