Combined multi-car elevator system

Abstract

The invention provides a combined multi-car elevator system which comprises a plurality of cars, at least two main rails and a plurality of switching rails, the switching rails are used for connecting two different main rails, the main rails and the switching rails are installed in hoistways, at least two main rails are arranged in one hoistway, and the switching rails are used for connecting two different main rails. The elevator system further comprises a linkage interlocking device, the two ends of the linkage interlocking device are detachably connected with the two to-be-combined communicated lift cars on the two adjacent main rails in the hoistway respectively, and at least one side wall of each lift car can be opened except the wall face where the car door is located. According to the elevator system, through the mode of combining the lift cars, in-out and transportation of oversized goods can be achieved, hoistway resources are not increased, independent operation of all the lift cars can be recovered after transportation is completed, the flexibility and passing efficiency of the elevator system are ensured, the stretcher form is not changed, and the general applicability is wider.

Description

technical field [0001] The invention belongs to the technical field of elevators, in particular to a combined multi-car elevator system. Background technique [0002] In modern social and economic activities, elevators have become an indispensable means of vertical transportation for people or goods. Since the invention of the elevator in 1854, the elevator car has been driven by wire rope pulleys. By setting up the machine room, traction motor and deceleration device on the top floor of the building, the wire rope is driven to pull the car and the counterweight on the track in the hoistway. run. This driving method makes it possible to run only one car in a single well, and the elevator in the single-car operation mode can still meet the use requirements in 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 have sprung up, and the shortcomings...

Problems solved by technology

[0005] However, for a multi-car elevator, if a single car is equipped with a size larger than that of an ordinary passenger elevator, the size of the shaft that the car runs through will be larger than that of the ordinary passenger elevator shaft, which leads to an increase in the size of the shaft. It wastes hoistway resources and increases the cost. On the other hand, it reduces the flexibility and traffic efficiency of the car switching of the multi-car elevator system
