Description

Annular elevator

Technical Field

The invention relates to the technical field of elevators, in particular to an annular lifting elevator.

Background

Elevators have become an indispensable tool in people's lives. The existing vertical transport elevator adopts a mode that one elevator car runs up and down in one hoistway. In a multi-storey public building with large people flow, even if a plurality of elevators are installed, the requirements of passengers in peak periods cannot be met, and a crowded scene appears in an elevator lobby frequently. In order to deal with the situation of elevator congestion, related patents are published, such as a single-shaft double-passage up-and-down independent operation vertical elevator disclosed in CN102229396A, and a car circulation and continuous hydraulic elevator disclosed in CN 1223960A.

In view of the practical needs of people's life, efficient elevator will become a new development direction. The prior patents of multi-channel, multi-car elevators are broadly divided into two forms: the common characteristic of the steel wire rope pulling type elevator is that the steel wire rope pulling type elevator is CN102229396A, and the hydraulic cylinder pushing type elevator is CN1223960A, the vertical movement and the horizontal movement are respectively completed by two sets of driving devices, and the movement is completed in an intermittent relay mode rather than in a discontinuous mode, so that the operation efficiency of the elevator is influenced. The steel wire rope pull type elevator (still taking CN102229396A as an example) can continuously run in a vertical channel, but only one car is arranged in one channel, so that the transportation efficiency of the channel cannot be improved. The hydraulic cylinder push type elevator (still taking CN1223960A as an example) utilizes a hydraulic rod to lift a car upwards from the bottom of the car, is limited by the stroke of the hydraulic cylinder, the car can only lift one floor once, then the car is supported by a movable supporting iron, the lifting hydraulic cylinder retracts, the horizontal hydraulic cylinder pushes out one car from the side surface of the bottom layer, the horizontal hydraulic cylinder retracts, the lifting hydraulic cylinder works again, each movement of the car is in an intermittent state, and the retraction time of one hydraulic cylinder is added, so the operation efficiency of the elevator is greatly reduced.
