Description

Multi-car intelligent parallel elevator

Technical Field

The invention belongs to the technical field of elevators, and particularly relates to a multi-car intelligent parallel elevator.

Background

Elevators have become an indispensable manned or cargo vertical transport vehicle in modern society and economic activities. Since 1854 the invention of elevators, elevator cars have been operated by wire rope sheave traction drive, and machine rooms, traction motors and reduction gears were installed on the top floors of buildings to drive wire ropes to pull the cars and counterweights to operate on rails in the hoistway. The driving mode enables only one elevator car to normally run in a single shaft, and the elevator in the single-elevator-car running mode can meet the use requirement on low-rise buildings and floors with small passenger flow. With the rapid development of modern cities, high-rise buildings and super high-rise buildings with large population density are pulled out, the defects of long elevator waiting time and low conveying efficiency of elevators in a single-car operation mode are continuously enlarged, and the traditional single-car elevator operation mode is difficult to adapt to the rapid development requirements of modern city buildings.

The multi-car parallel elevator adopts the direct drive technology without the traction steel wire rope, so that a plurality of elevator cars can be operated simultaneously in the same shaft, and the elevators among the shafts can be switched to operate in the shafts, so as to realize the overrunning operation.

The multi-car intelligent parallel elevator needs to be switched to a nearby hoistway to operate from one hoistway through a switching mechanism, and the switching mechanism is provided with an arc rail to realize transition between an inclined rail and a vertical rail. When the elevator runs on the arc rail and the inclined rail, the elevator suspension and the car can rotate relatively, so that the car cannot deviate from a vertical state greatly, and the riding comfort of passengers is improved.

The existing elevator car without the traction steel wire rope is hung on the car through a suspension device, and the car is hinged with the suspension device, so that the effect that the car can rotate relative to the suspension device is achieved. However, the mode of hanging the car through articulated hanging axle can have the possibility that the hanging axle breaks off, and when hanging the axle fracture, the car will drop the well, and the overspeed protection system can't implement the protection.
