Title:
GRADIENT-ADAPTIVE INCLINED RUNNING SPECIAL ELEVATOR
Document Type and Number:
WIPO Patent Application WO/2017/071029
Kind Code:
A1
Abstract:
A gradient-adaptive inclined running special elevator, comprising a buffering device (1), an elevator car system (2), a ramp guide rail system (4), a counterweight system (7), a traction machine (11), a speed-limit rope speed limiter (12), and a traction rope guide wheel (13). Both ends of the traction rope are respectively connected to the elevator car system (2) and the counterweight system (7), and traction lifting is implemented, being driven by means of the traction machine (11) and guided by means of the traction rope guide wheel (13). Automatic levelling of the car body by means of an automatic levelling assembly is necessary in order to adapt to changes in gradient; forced guidance of the traction rope is implemented by means of a traction rope lifting apparatus (5) and a traction rope pressing apparatus (6), and forced guidance of the speed-limit rope is implemented by means of a speed-limit rope lifting apparatus (16) and a speed-limit rope pressing apparatus (14). The present elevator is structurally simple, safe, and reliable, has a wide application, and can implement running of an inclined elevator on a variable gradient track.
