Pumped storage power station inclined shaft construction variable-angle expanding excavation trolley

The invention discloses a pumped storage power station inclined shaft construction variable-angle expanding excavation trolley which comprises a trolley bottom plate (2) parallel to an inclined shaft rail (1). The side, corresponding to the inclined shaft rail (1), of the trolley bottom plate (2) is connected with trolley wheels (3), and the other side of the trolley bottom plate (2) is connected with a horizontal main platform (6). A roll shaft (7) rotationally connected with one end of the main platform (6) is arranged at the top of the trolley bottom plate (2), the other end of the main platform (6) is connected with inclined trolley columns (8), and the lower portion of the middle of the main platform (6) is connected with vertical trolley columns (9). The middles of the inclined trolley columns (8) and the middles of the vertical trolley columns (9) are connected with jacks (10). The pumped storage power station inclined shaft construction variable-angle expanding excavation trolley has the advantages of
