Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention improves the transportation efficiency by organically combining a self-propelled elevator system, which is installed in the same building and is capable of traveling vertically and horizontally, and a plurality of rope type elevator systems. A possible elevator system.

[0002]

2. Description of the Related Art Most conventional elevator systems have been widely used except for a hydraulic elevator that raises and lowers a car by using a hydraulic plunger and a winding drum type elevator used in a relatively small capacity area. , A method in which a car and a counterweight are connected in a rope-like shape with a rope, and one car is arranged in one hoistway.

As shown in FIG. 6, this slip-type elevator system includes a car 1 and a counterweight 2 in a hoistway.
Guide rails (guide rails) 3 and 4 are provided and arranged between them, and a rope 8 is used to hang them both through the sheave 6 and the deflecting sheave 7 of the hoisting machine 5 installed in the machine room above the hoistway. It is a structure that is connected in a shape. In recent years, a three-phase induction motor has been widely used as a driving electric motor for the hoisting machine 5, and an inverter device having a microprocessor in its control device has been widely used.

In such a slip-type elevator system, the traveling force of the unbalanced load with the counterweight 2 is enough to drive the car 1 except for the traveling loss by the machine. It has a feature that the capacity of the control device can be small, and since it is a system that has been widely used from the past, the technology is established in terms of performance and safety, and it is reliable.

However, in recent years, as a future prospect,
A new idea of an inter-floor transportation system has been proposed to meet the demands of skyscrapers, etc., but one of the proposed new transportation systems is that the car itself runs without using ropes. This is a self-propelled elevator system, which is a concept of a vertically and horizontally movable traveling elevator system having a configuration capable of traveling not only in the vertical direction but also in the horizontal direction.

The concept of this self-propelled elevator system is as follows:
It breaks down the existing concept of one car for one hoistway and is attracting attention as an innovative technology capable of running a plurality of cars on one hoistway.

FIG. 7 shows the structure of such a self-propelled elevator system which can be vertically and horizontally run. A linear motor secondary conductor 10 is installed in a plurality of cars 9 and is installed in a hoistway (elevating shaft). Linear motor primary coil 11
The driving force is obtained by the magnetic force between the and. And, as a safety device, a shock absorber 13 for reducing the impact caused by the collision of the brake 12 and the car 9 with each other,
Further, a superconducting magnet 14 provided inside or under the shock absorber 13 is provided in order to perform connected traveling. Further, a suspender 15 and a movable plate 16 for horizontal traveling are installed on the uppermost floor, and a hydraulic jack 17 is similarly installed on the lowermost floor so that one elevator shaft can travel a plurality of cars 9 I am trying.

[0008]

However, in the climbing elevator system shown in FIG. 6, generally only one elevator can be installed in one hoistway (elevating shaft), so the elevator system can be installed in a building. From the viewpoint of occupied space, it is not preferable in terms of efficiency because it requires a space of (elevation shaft cross-sectional area per elevator x number of floors including express zone), and in particular, there is a tendency for higher buildings. Today, the higher the skyscrapers, the more pronounced this tendency.

On the other hand, as shown in FIG. 7, in a self-propelled elevator system in which a plurality of cars are run on one elevating shaft, a plurality of elevating shafts are equipped with a plurality of cars as compared to a slip elevator system. Since it is possible to install a car, it is expected to be improved from the viewpoint of the space occupied by the building. However, in the operation management, one elevator shaft has multiple cars, Even if many elevator cars are installed on one elevator shaft, there is a tendency for time to increase from the viewpoints of passenger waiting time and boarding time.
It is expected that operation control will become difficult due to the congestion of elevator cars.

Further, as compared with the slip-type elevator system of FIG. 6, a large capacity drive thrust is required and a linear motor primary coil is required to be installed in the hoistway (elevating shaft), so that the cost is reduced. It has the drawback of increasing significantly.

The present invention provides an elevator system which can improve transportation efficiency, occupy less space in an elevator system in the same building, can improve transportation efficiency, and can suppress elevator equipment cost. The purpose is to

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing the configuration of an elevator system according to an embodiment of the present invention. In the present embodiment, it is assumed that the building has 31 floors (floor) above ground and 1 floor below ground (B1 floor) and has 12 vertical shafts, but the present invention is not limited to this. The first and second shafts are provided with first and second self-propelled elevator systems (both systems form a self-propelled elevator bank) for traveling a car that can travel vertically and horizontally. The first floor and the 31st floor above the ground each have a lateral traveling path through which the car can move in the lateral direction (floor direction).

In each of the first and second self-propelled elevator systems, eight cars are installed in a shaft, the first shaft is a downward operating lift shaft, and the second shaft is an upward operating lift shaft. , 8 self-propelled elevator cars move up the 2nd shaft when departing from the B1 floor, move horizontally to the 1st shaft on the 31st floor, and again move to the 2nd shaft on the B1 floor The first and second shafts can be circulated. The main floors of the stop floors of the self-propelled elevator system are B1st floor, 1st floor, 6th floor, 10th floor, 16th floor, 21st floor, 2nd floor.
The 6th floor and the 31st floor are set, and the zones other than the above are set as express zones so as not to stop.

All of the systems can move up and down between the B1 floor and the 16th floor, and the rope type low rise bank is configured by these five rope type elevator systems.

Therefore, the hall passengers will go from the main floor to the floor near the destination floor by this self-propelled elevator and transfer to the rope elevator at that floor. On the contrary, passengers from the floors other than the main floor will get on the rope-type elevator, and if there is no destination floor in the bank, transfer to the self-propelled elevator on the nearest main floor. That is, in the structure of the entire building, the self-propelled elevator bank is configured to serve only the main floors except for the express zones on the B1st floor to the 31st floor, and to perform the basic transportation function that is the backbone of passenger movement.

According to the present embodiment described above, a plurality of self-propelled elevator systems are installed in a small number of shafts, and only the main floors limited in advance are serviced, so that the operation management can be performed relatively easily. Therefore, basic transportation for moving to the main floor in the building can be achieved.

Further, as a local transportation means for moving from the main floor to the passenger's destination floor, since it is possible to move by a rope type elevator system which is under normal group management control, the elevator system in the building occupies It is possible to improve the space used and to reduce the equipment cost of the elevator.

Further, the self-propelled elevator system is used as the main transportation means in the building so that only the main floor is serviced, and the local elevator that can serve each floor from the main floor is constructed by the rope type elevator system, thereby reducing the equipment cost. Since the self-propelled elevator system, which is expensive and difficult to control the operation of multiple elevators, is limited to the transportation means to the main floor, the number of operating lifting shafts can be limited to a relatively small number, which reduces equipment costs. In addition, since the number of service stop floors is limited, operation management can be realized relatively easily.

Further, the rope type elevator system is
Since the main purpose of transportation is only movement from the main floor,
It is possible to reduce the number of elevator group control units for each bank, and because it is not necessary to have an express zone for high-rise banks, it is possible to use elevator equipment at a relatively low speed comparable to low-rise banks, thus reducing equipment costs. And the effective floor area in the building can be expanded.

Further, since banks other than the low-rise bank do not have an express zone as in the conventional case, the express zone space can be utilized as an effective floor, so that the effective floor area can be dramatically expanded.

The present embodiment is not limited to the above-mentioned embodiment, but various modifications can be made without departing from the scope of the present invention. For example, in the present embodiment, the vertical and horizontal self-propelled elevator has been shown by the demand system by the hall call. However, the hall call is eliminated, and each hall is provided with a hall display device for arrival guidance and destination floor guidance. Alternatively, each self-propelled elevator may have a method of circulating the top floor / bottom floor by fixed scheduling like a train. In such a case, the passenger can determine the route to the destination floor according to the guidance from the hall display device of the self-propelled elevator hall.

Further, in this embodiment, the self-propelled bank and the rope type bank are not interlocked,
A transfer button is installed in the self-propelled elevator, and if the transfer button is registered before the specified time before the self-propelled elevator stops on the main stop floor, the landing call for the rope-type local elevator bank is automatically registered and the transfer is changed. It may be configured to improve the above usability.

Regarding the structure of the building, in the embodiment, the rope type elevator is divided into high-rise and low-rise banks, and the self-propelled elevator bank has one shaft for rising / falling, but the present invention is not limited to this. Raise the elevator bank /
2 shafts each descending, and transverse floors are set up in the middle floor,
Depending on the elevator demand, it may be set so that it can return to the middle floor. The rope bank is not limited to the two-layer bank structure, and the self-propelled elevator bank and the service floor number may not be matched.

[0048]

According to the present invention described above, it is possible to balance the self-propelled elevator system and the rope-type elevator system, and to realize a structure in which the mutual advantages are organically combined. As a result, the present invention can provide an elevator system that can improve transportation efficiency, occupy less space in the same building, can improve transportation efficiency, and can suppress elevator equipment costs. .
