Single-wheel cycled multi-car elevator

Abstract

The invention discloses a single-wheel cycled multi-car elevator comprises cars, a driving mechanism and car positioning rails, wherein each car is provided with a car wheel; the car wheels are arranged inside car wheel positioning rails; each car wheel positioning rail comprises car wheel positioning rail vertical sections and car wheel positioning rail curved passage sections; each car is connected with the driving mechanism through a rotary disk and a connecting shaft; and each car positioning rail comprises car positioning rail vertical sections and car positioning rail curved passage sections. According to the single-wheel cycled multi-car elevator, the driving mechanism drives the cars to move along the car positioning rails, while the car wheels always run along the car wheel positioning rails so as to ensure that the cars cannot turn over during the running process; and the rails are continuous, so that the cycle of the cars is relatively simple. A plurality of cars can exist inside the car positioning rails simultaneously, so that the well space utilization rate of the elevator is improved, the elevator waiting time is shortened, the transport capacity is increased, and the single-wheel cycled multi-car elevator is particularly suitable for being used in high-rise buildings.

Description

technical field [0001] The invention relates to a circular elevator, in particular to a multi-car elevator. Background technique [0002] In traditional sheave traction hoistway elevators, only one car can run in each hoistway. Elevators with this structure are more practical in low-rise buildings, but for more and more high-rise buildings in modern cities, there are problems such as small number of cars, low transportation capacity, and long waiting time. use. The existing solution is to install more single-car elevators by increasing the number of elevator shafts, and double-deck car elevators using traditional sheave traction technology, which improves the transportation capacity to a certain extent and shortens the waiting time for elevators, but A large number of elevator shafts have taken up a lot of valuable building space and building costs, and have not fundamentally solved the problem. For high-rise and ultra-high-rise buildings with many people and heavy loads,...

Problems solved by technology

However, for this kind of multi-car elevator and its circulation system, the conversion mechanism needs to remove the car and its corresponding track when the car circulates and avoids. There is a discontinuity in the running track of the car, and the conversion mechanism needs a large driving force. , cycle avoidance process is complex and other issues

In addition, the utility model with the patent number "CN201020659140.7" discloses "a circular multi-car elevator", which proposes a multi-car elevator that can realize the circulation of multiple cars in a circular track, but there are When the car circulates from one hoistway to another, the car has the problem of overturning; at the same time, this multi-car elevator does not consider the problem of the track switch, and the car can only run in a closed cycle, and the operating efficiency is not high. limited
