Description

Rope type multi elevator

The present invention relates to a rope-type multi-elevator, and more particularly, by using a rope to arrange a plurality of elevator cars (Car) in series in the same one hoistway, so that it can be operated independently, installation of the elevator And it relates to a rope-type multi elevator to maximize the running efficiency.

Recently, high-rise buildings are being constructed one after another due to the high density of the city. Accordingly, various types of elevators are proposed to move more passengers quickly and efficiently. There is a double elevator that can arrange and operate two or more elevator cars in series, and a ropeless multi elevator.

First, FIG. 1 illustrates a configuration of a conventional double elevator, in which two first and second cars 2a and 2b are coupled in series in a vertical direction in the same single hoistway 1. In the center of the upper surface of the first car 2a, a rope engaging portion 7 is formed in which a rope 3 for lifting up and down the first and second cars is wound.

In addition, at the other end of the rope 3, a balance weight 6 is provided to provide a balance when the first and second cars are lifted, and the first and second cars are driven using the rope. A drive / reduction gear 5 including a driving motor for the driving, and a plurality of rollers 4a, 4b, and 4c are provided to secure the movement path of the rope.

Accordingly, the double elevator can move twice as many passengers at once as compared to the normal elevator in which only one car is lifted on one hoistway.

However, the double elevator as described above, since the first car and the second car are integrally coupled to operate at the same time, even when moving a small number of passengers, the two cars are simultaneously driven, thus causing unnecessary energy consumption. There is this.

On the other hand, Figure 2 shows a configuration for a conventional ropeless multi elevator, the ropeless multi-elevate, two first and second cars (2a, 2b) in the same one hoistway 1 in the vertical direction Arranged in series, but separated so that each can operate independently, the rail guide 12 is formed on both side surfaces of the first and second cars, the lifting rail 13 is installed vertically on both sides of the hoistway That is, it is connected with a lifting rail for providing a lifting path of the first car and the second car.

In addition, on both sides of the elevating rail 13 and the first and second cars 2a and 2b, primary members 14 and 2 for allowing the first and second cars to move up and down by electromagnetic force. The vehicle side members are provided respectively.

Accordingly, the ropeless multi-elevate, unlike a conventional elevator in which only one car is lifted on one hoistway, can be used to quickly move more passengers by using a plurality of cars that are independently separated and operated. In the case of moving a small number of passengers, only one car can be selected and operated, so as to prevent unnecessary consumption of energy as in the double elevator described above.

However, the ropeless multi-elevator as described above is driven by the electromagnetic force induced between the elevating rail and the cars, respectively, on the primary side member and the secondary side, so that a large amount of energy is consumed. Even in the state of stopping in the middle floor, the electromagnetic force for stopping and fixing the car is required, which leads to the continuous generation of large power consumption, as well as to the conventional rope type elevator using rope in case of power failure or disaster. There is a problem that can cause a large accident.

Therefore, the present invention has been created to solve the above problems, it is possible to arrange a plurality of elevator cars (Car) in series in the same one hoistway, and to operate them independently, while safe driving and energy consumption It is an object of the present invention to provide a rope-type multi elevator using a rope method that can be minimized.
