Problems solved by technology

[0003] Some cities at home and abroad have adopted a double-layer or multi-layer operation and maintenance depot structure when building modern tram vehicle bases. Although the floor area has been reduced, it is necessary to extend the vehicle access and exit lines to make the tram crawl. Slope, so that the tram from the first floor of the vehicle base to the second floor or higher, which will undoubtedly require an increase in the area of ​​the vehicle base

Abstract

The invention provides a tramcar lifting device. The tramcar lifting device comprises at least one lifting unit, wherein one lifting unit comprises a lifting platform, a lifting power device, a support device, a base support mechanism and multiple guiding wheel sets. The tramcar lifting device provides driving force for the lifting platform through the lifting power device, and a support pile is adopted to provide support for the lifting platform, and therefore the vertical transportation towards the tramcar is realized, the trouble that expansion a vehicle entrance and exit section line enables the tramcar to enter the high level of a vehicle base is avoided, and the floor space of the vehicle base is reduced. Further, multiple guiding wheel sets are also arranged between a second side wall of the lifting platform and a first side wall of the base support mechanism, not only does the swinging in the horizontal direction of the lifting platform during the lifting or dropping process not exist, but also the resistance of the lifting platform in lifting or dropping is also reduced.

Description

technical field [0001] The invention relates to the technical field of hoisting, in particular to a hoisting device for a tram. Background technique [0002] At present, domestic modern tram vehicle bases occupy a large area, especially the application warehouse and maintenance warehouse for vehicle parking and maintenance, which increase the project investment scale and cost. [0003] Some cities at home and abroad have adopted a double-layer or multi-layer operation and maintenance warehouse structure when building modern tram vehicle bases. Although the occupied area has been reduced, it is necessary to extend the vehicle access section line to make the tram climb. Slope, so that trams drive into the second floor or higher floors from the first floor of the vehicle base, this undoubtedly needs to increase the area of ​​the vehicle base. Contents of the invention [0004] The invention provides a hoisting device for trams, which can transport trams between multi-storey ...
