Description

Traction-driven multi-car-shared multi-well circulating operation elevator

The technical field is as follows:

the invention belongs to the technical field of elevators, and particularly relates to a traction-driven multi-car-shared multi-well-way circulating running elevator.

Background art:

with the popularization of high-rise buildings, elevators become indispensable vertical transportation equipment in buildings, and after the development of nearly one hundred years, the safety, reliability and energy conservation of the elevators are greatly improved, the driving mode of the elevators is gradually a driving mode dominated by traction driving, wherein one end of a traction rope is connected with a car, the other end of the traction rope is connected with a counterweight, and the gravity of the car and the counterweight causes the traction steel wire rope to be tightly pressed in a traction wheel groove to generate friction force, so that the motor rotates to drive the traction wheel to rotate, the steel wire rope is driven, the car and the counterweight move relatively, namely the car rises, the counterweight falls, the counterweight rises and the car falls, thereby achieving the purpose of safely and efficiently driving the elevators to move vertically, at present, the mature traction driving has dominated in elevator application, and the traction driving can greatly reduce the volume of a transmission mechanism, the power consumption is greatly reduced, the elevator stroke is greatly increased, the popularization of traction drive enables a high-speed long-stroke elevator with good universality, safety and energy conservation to become a mainstream machine type applied in the market at present, but the traction drive elevator mainly operates in a single car and a single shaft at present, and has the defect of low shaft utilization efficiency, along with the rapid increase of super high-rise buildings in modern cities, the length of the shaft in the building is continuously lengthened, the time for the car to stop at each layer and go back and forth once at high and low layers is greatly prolonged, the utilization rate of the shaft is greatly reduced, the shaft waiting time of people is increased, in order to ensure the conveying efficiency of the high-rise building elevator and reduce the shaft waiting time of people, architects have to build more shafts in the building, the number of the elevators in the modern skyscraper building is dozens or even hundreds, and the shaft area of the elevator usually occupies more than 20 percent of the total area, this greatly occupies the usable floor space of the building and increases the construction cost. Therefore, how to improve the utilization ratio of the elevator shaft, on the premise of ensuring and improving the conveying efficiency of the elevator, the number and the occupied area of the elevator shaft are reduced, and huge social benefits and economic benefits are achieved.

Because the single-car elevator is difficult to meet the requirement of vertical transportation of large passenger flows of high-rise buildings, people begin to research a method for increasing the number of cars in an original elevator shaft, a plurality of teams are in research and development of double-deck elevators and multi-car circulating operation elevators, and certain achievements are achieved in the aspects of structural design, multi-car group optimized operation management, adjacent car anti-collision control and the like, the initial double-deck elevator is formed by hanging 2 cars together and has the same operation and stop states, although the passenger carrying capacity is increased, the improvement of the operation efficiency is not greatly facilitated; the existing double-deck elevator is upgraded into 2 traction driving cages which independently run, anti-collision management is arranged among the traction driving cages, the 2 cages optimally allocate respective running routes of the 2 cages by a control system according to calling instructions of people outside the elevator, although partial efficiency is improved, the 2 cages still run vertically in an upper section and a lower section in the same shaft, the efficiency potential is limited, and the passenger possibly has inconvenience of needing to transfer when arriving at a target floor; the multi-car circulating elevator can effectively improve the utilization efficiency of an elevator shaft theoretically, but in the existing design concept, the multi-car circulating elevator is also based on chain transmission or rack transmission, the cars are respectively hung on chains in series, all the cars in the system have the same running and stopping states at any time, cannot run independently of each other and have extra energy consumption, and the improvement of the running efficiency is not greatly facilitated; at present, as the technology of a linear motor matures, a team develops a magnetic suspension multi-car direct-drive cordless elevator through the technology, and although the magnetic suspension driving technology has matured commercial application on a high-speed train running horizontally, the problems of high cost and difficult driving exist on a vertical running cordless elevator drive.
