Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a curved elevator with an automatic leveling elevator cage. Background Art

[0002] Ordinary construction elevators transport construction personnel or materials from the ground to the desired height by moving the cage up and down, or transport personnel and materials from a specified height to the ground; the working rails of ordinary construction elevators are vertical to the horizontal plane, but in the construction of some thermal power plant cooling tower projects and bridge columns, the surface of the building is often curved, and ordinary construction elevators cannot meet their construction needs. Most construction parties adopt the method of building a high-speed derrick platform outside the building. Construction personnel walk to the construction site at a height of tens of meters or more than one hundred meters through the stairs set in the derrick platform, which is very inconvenient, with high labor intensity and extremely low work efficiency, and poor safety; or use ordinary construction elevators, installed on derricks or other temporary steel structures, when the elevator cage reaches a certain height, it reaches the construction site through the temporary construction platform built on the steel structure; this construction process is very traditional and troublesome. Every time the project is increased in height, the construction platform needs to be rebuilt, and the distance between the construction platforms is getting longer and longer.

[0003] At present, the existing technology also manufactures the running guide rail of the elevator cage into a curved shape to suit the curved shape of the engineering surface and to meet the requirement that the guide rail is close to the building or formwork surface to the greatest extent. However, when the cage climbs along the curved track, the bottom of the cage cannot remain horizontal as the angle of the cage's running trajectory changes, resulting in the driver and passengers being unable to stand upright. This will make the driver and passengers feel that they are in an unsafe state and the transported goods are also in danger of tipping over.

[0004] For this reason, a curved elevator with an automatic leveling elevator cage is proposed. Utility Model Content
