Multi-car balance elevator

Abstract

The invention provides a multi-car balance elevator. The elevator comprises an elevator frame, cars, a following chain cable, a driving wheel and a driven wheel; the following chain cable is wound on the cars, the following chain cable is driven through the driving wheel and the driven wheel to run, the cars, the following chain cable, the driving wheel and the driven wheel are arranged in the elevator frame, the cars comprise car bodies of the odd number, the car bodies of the odd number are divided into two sets on average, the two sets of car bodies are mounted on the two sides of the following chain cable to synchronously move, and a supporting frame used for adjusting the motion width of the chain cable is arranged on the following chain cable. The cars with the same number are arranged on the two sides of the following chain cable, use of a compensation chain is removed, in the ascending and descending process, weight balance of the elevator can be kept all the time, some unnecessary unsafe factors are avoided, other problems caused by adding of the compensation chain are solved, the number of persons borne by the elevator within the same time can be increased, and the elevator has the great advantage in the rush hour or the places, like the shopping mall with the large population density.

Description

technical field [0001] The invention relates to the technical field of elevator components, in particular to a multi-car balanced elevator. Background technique [0002] With the rapid development of high-rise buildings in our country, elevators are widely used in life, work and production. The traditional elevator consists of a car, a counterweight, a wire rope and its control system. Each group of elevators has only one car to move up and down in the elevator room. The number of people carried by the elevator with this structure is limited and the efficiency is not high, so it is difficult to quickly evacuate a large number of people in a short period of time when there is a danger and it is necessary to evacuate people urgently. Another one is that a compensation chain is generally installed in the elevator to compensate the weight of the wire rope for the elevator, but the compensation chain itself has no other practical functions, which is a bit of a waste of resources...

AI Technical Summary

Problems solved by technology

However, there must still be a compensation chain function in this scheme, and there is still a certain risk. Therefore, there is no corresponding improvement measure for the counterweight method or method in the prior art, and the defects still exist
