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

Abstract

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 being convenient to demount and mount and wide in application range, the expanding excavation construction cost of a power station can be reduced, the field welding workload is reduced, and the structural stability and safety are improved.

Description

technical field [0001] The invention relates to an expanding and excavating jumbo for inclined shaft construction of a pumped-storage power station, in particular to a variable-angle expanding and excavating jumbo for inclined-well construction of a pumped-storage power station. Background technique [0002] The trolley, that is, the platform car, is generally used in tunnels, hydropower inclined shafts and mining systems, etc., to provide operators with an operating platform. Commonly used are tunnel lining formwork support trolley, mine excavation trolley and inclined shaft expansion excavation trolley, etc. It is inconvenient to assemble and disassemble the excavation jumbo for the expansion of the pumped storage power station. Moreover, the slopes of inclined shafts in different pumped storage power stations are different, and the existing excavation expansion vehicles cannot meet the construction requirements of different slopes. Excavation costs are high. Therefore,...

It is inconvenient to assemble and disassemble the excavation jumbo for pumped storage power station expansion

Moreover, the slopes of inclined shafts in different pumped storage power stations are different, and the existing excavation expansion vehicles cannot meet the construction requirements of different slopes. Excavation costs are high

Therefore, the existing pumped storage power station expansion trolley has the problems of inconvenient disassembly and assembly, a small scope of application, and high construction costs for power station expansion.
