Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a universal traveling elevator for simultaneously traveling a plurality of universal traveling elevator cars using a linear motor as a drive device and capable of traveling in vertical and horizontal directions in the same traveling path.

[0002]

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

In this crane type elevator system, a hoisting machine installed in a machine room above the hoistway is provided with a car and a counterweight provided in the hoistway with guide rails (guide rails) provided therebetween. Through the sheaves and deflecting sheaves of the two, it is a structure that connects the two in a rope shape with a rope.

In recent years, a three-phase induction motor has been widely used as a driving motor for a hoisting machine, and an inverter device having a microprocessor in its control device has been widely used.

In such a slip elevator system, a balance weight and a driving force corresponding to an unbalanced load are sufficient to drive the car, except for a traveling loss caused by a machine. It has a characteristic that it requires a small capacity, and since it is a method 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 concept of an inter-floor transportation system has been proposed to meet the demands of skyscrapers and ultra-high-rise buildings, but one of the proposed new transportation systems is one of the This is a self-propelled elevator system in which the car itself travels, which is a concept of an elevator system capable of traveling vertically and horizontally with a configuration capable of traveling not only vertically but also horizontally.

The concept of this self-propelled system breaks through the existing concept of a single car in one hoistway, and is an innovative technology capable of running a plurality of cars in one hoistway. Is being watched as.

FIG. 5 shows the construction of such a vertically and horizontally self-propelled elevator system.
The linear motor secondary conductor 2 is installed in the motor, and the driving thrust is obtained by the magnetic force between the linear motor secondary coil 2 and the linear motor primary coil 3 installed in the hoistway (elevating shaft). As a safety device, the brake 4 and the shock absorber 5 for alleviating the impact caused by mutual collisions of the car 1 and the superconducting magnet 6 provided inside or under the shock absorber 5 for connecting traveling are provided. There is. Furthermore, on the top floor, a hanging machine 7
And a movable plate 8 for horizontal travel, and a hydraulic jack 9 on the bottom floor as well.
It is possible to drive.

Various linear motors are known as a linear motor, but as a method in which the structure is relatively simple and a large thrust can be obtained, neodymium iron type or samarium cobalt type secondary conductors are used. A linear synchronous conductor (LSM) in which a permanent magnet is used and a coil having a three-phase AC winding structure is laid on the primary conductor is used.

[0010]

In the proposed self-propelled elevator system as described above, one elevator car does not occupy one hoistway space as in the conventional slip type elevator system. Since multiple cars can be arranged, transportation efficiency can be increased especially when the length of the hoistway is large, such as in a skyscraper or an ultra-high-rise building. In this case, if a plurality of cars 1 are arranged in a plurality of hoistways, the efficiency will be further improved.

However, in such an elevator that can travel freely, it is not possible to drive the elevator in the shortest time as instructed by the customer in the car as in the conventional case, and scheduling according to the traffic demand in the building is possible. Driving is required.
This is to reduce the lifting space that traverses the building.

[0012] In general, this traveling path is arranged so that each stopable floor can be moved horizontally, and at other portions, the express zone is set as long as possible so that high speed traveling can be achieved. It is required to improve the factor. In order to meet this demand, it is necessary to restrict entry into zones where high-speed driving is possible and to carry out effective operation.

This structure is similar to the structure of the current roads. Express zones are highways, vertical and horizontal sections are general roads, vertical and horizontal controls are traffic lights, and entrances and exits to express zones are controlled. Corresponds to the toll booth. In other words, in the past, since all hoistways were highways, it was possible to respond optimally to user requests, but due to the space of the building, the number of elevators could not be increased, Since the elevator is in charge of traffic demand, it often caused an increase in waiting time. Therefore, the waiting time for traffic flow control in the hoistway is expected to be long, while the waiting time is shortened by the increase in the number of cars even in an elevator that can travel freely in the vertical and horizontal directions.
Therefore, the construction of a system that can efficiently control this traffic flow is expected.

Further, the universal traveling elevator can freely operate in the vertical and horizontal directions, but in actuality, it is most efficient in terms of system to move at high speed in the vertical direction, and some kind of mechanical movement is required for the horizontal movement. It is conceivable that slow movement will occur due to various auxiliary mechanisms. Further, it is not efficient to control a plurality of cars in the vertical direction by a linear motor drive to control a single hoistway.

The present invention has been made in order to solve such a problem, and provides a universal traveling elevator which can avoid the problems of a large-capacity movement of a car and a collision, and enables efficient driving. The purpose is to do.

The following effects can be obtained. That is, it is possible to avoid a large capacity movement of a plurality of cars and a collision problem. In addition, since the three functions of high-speed transportation, transportation with living space, and zone-selective transportation are separated, efficient operation can be performed.

[0023]

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, as shown in FIG. 1 (longitudinal sectional view of an elevator traveling path) and FIG. 2 (transverse sectional view of an elevator traveling path), a large-capacity longitudinal traveling is performed as a hoistway (traveling path). A traveling route (low-speed vertical traveling route: general zone) 10, a high-speed longitudinal traveling route 11 and a zone selection route (horizontal moving route) 12 for selecting these traveling routes 10 and 11 are formed, and the car is loaded depending on the state of the traffic flow. It is configured so that it is possible to select either one to pass. With this configuration, the living space of the building is effectively used and the operation efficiency of the elevator is improved.

A mechanical lift drive mechanism 13 is constantly operating on the large-capacity vertical traveling path 10, and the car 1 is installed in a predetermined space of the lift drive mechanism 13 when necessary.
Move vertically.

The lift drive mechanism 13 is driven at a low speed as in the current parking lot building, and the lift mechanism (fork, etc.) into which each car 1 can be inserted is used to drive the individual car 1.
Is being driven.

Next, the high-speed vertical traveling road 11 (hereinafter referred to as the express zone) becomes a high-speed moving road by the original linear drive.
The car 1 itself may be created as a simple moving space regardless of the type of traveling road, and the propulsive force is given from each traveling road side. Further, these traveling paths are configured to move on the horizontally traveling movable plate 8 by a zone selection path 12 that is linearly driven.

As described above, the traffic demand in the building includes movement of the standard floor where many people come and go and surrounding floors and long-distance movement such as upper floors. Low-speed vertical road 1 that supports the former
Reference numeral 0 is a configuration of a traveling path which is configured to be vertically movable in a circulating manner on each service floor.

The express zone 11 connecting the next distant floors is a high-speed moving path and runs several hundred meters. In the express zone 11, the movement time is required to be shorter than that in the general zone 10, so that the operation of simply moving laterally will rather disturb the flow of traffic.

Further, the zone selection path 12 moves in the horizontal direction, so that a plurality of general zones 10 and express zones 11 can be selected.

This horizontal movement method is easy to implement by a mechanical mechanism.

A method of operating the zone selection path 12 according to the present invention will be described with reference to the flow chart of FIG. In this flowchart, the car 1 is from the general zone 10 to the express zone 1
The procedure for moving to 1 is described. In this case, a process for avoiding a collision with another car 1 while traveling in the zone is described.

Further, this flowchart is executed by the processing of the group management operation control device (not shown) which controls the operation of the plurality of cars 1 or the operation control device (not shown) in each car 1. The arrangement of these control devices is normally arranged in a general elevator system, and the car 1 is controlled in the elevator machine room.

In step 1, running in the general zone 10 is shown.

The car 1 is driven by the lift drive mechanism 13 to move a plurality of cars 1 in a large capacity. The car 1 is horizontally moved to the general zone 10 from the living space shown in FIG. 2 and incorporated into the mechanism, and a plurality of cars 1 are connected to operate.

In step 2, it is determined whether the zone needs to be changed. This is determining whether control to the express zone 11 is required. This requires a considerable amount of time to travel to the destination floor in the general zone 10, so after traveling to the position where the express zone 11 can be changed, the necessary time is determined and the change to the express zone 11 is made.

In step 3, movement to the zone selection path 12 is shown. In FIG. 2, the car 1 is traveling at a low speed in the general zone 10 by the drive mechanism 13, and the general zone 10 is switched to the zone selection path 12 at the switchable position.
Therefore, the vehicle moves laterally from the zone selection path 12.

After that, the car 1 moves on the horizontal moving plate 8 and has an entry into another zone at a predetermined position.

In step 4, the movement from the zone selection path 12 to the express zone 11 is shown. Contrary to step 3, step 5 shows movement to the express zone 11.

The movement to the express zone 11 is instructed by the traveling control conductor (secondary conductor etc.) attached to the building when the car 1 is traveling, but of course there is a risk of collision if there is not enough space. This calculation result is processed to avoid the collision. In general, this express zone 11
It is preferable for safety that there is only a single car 1, and when multiple cars 1 are mixed, 1 in the driveway
It is necessary to provide a space at a distance of 00 m or more.

In step 6, driving in the express zone 11 is shown.

In the express zone 11, high-speed transportation, which is one of the advantages of the self-propelled elevator, is used to drive to the higher floors.

With the above processing, the traveling control of the universal traveling elevator becomes possible.

FIG. 4 is a diagram showing the details of the general zone 10 and the zone selection path 12 in FIG. 1. The general zone 10 uses a circulation type gondola to travel at a low speed in a living space (living area) in a building. To do. A feature of this case is that the car 1 is located in the living space and is incorporated into the gondola 14 in the general zone 10 to run when necessary.

The gondola 14 is connected to the drive rope 15 via a fixing mechanism 16, and thrust is applied while the fixing mechanism 16 is connected to the drive rope 15. When the fixing mechanism 16 is released, the gondola 14 is stopped and the car 1 is permitted to enter.

At this time, it is necessary to implement a mechanism so that the gondola can be stopped for a short time at a position where it is required to get in and out of the building at a speed that is slow enough to get in and out of the running road and the inside of the building is fast. . This mechanism can be implemented by disconnecting the fixing mechanism and the gondola, and can run without stopping the car 1 other than the boarding / alighting car.

As the absorption of this time, as shown in the lower part of FIG. 4, the gondola stops after the entry position to absorb the time. Of course, when the car 1 is crowded, the car 1 at the bottom is temporarily stopped.

According to the embodiment of the invention described above, the general zone 10 and the express zone 11 are separated, so that the driving direction of the universal traveling elevator considered in the ultra-high-rise building is relatively easy. Therefore, it is possible to avoid the large-capacity movement of a plurality of cars and the collision problem, which are disadvantages of the universal traveling elevator. Particularly, there is an advantage that an efficient riding comfort can be provided without reducing the traffic volume in the express zone 11 which is required to move at high speed, and the influence of a traveling shock, which is a problem in vertical and horizontal traveling, can be suppressed. effective.

Further, as compared with the conventionally proposed vertical / horizontal free running, the three functions of high speed transportation, movement to the living space, and zone selective transportation are separated so that efficient operation can be performed.

Furthermore, since the space occupied by elevators, which is a problem in ultra-high-rise buildings, can be reduced, the required elevator space can be reduced by the number of cars currently in question, and the space can be used as a living space, which leads to an efficient operation. It can have a good building structure.

Further, the car 1 from the living space can be treated like an independent car unlike the conventional one, and not only high-speed movement but also the construction of the private elevator according to the request of each user is implemented. it can.

Further, of the dangerous vertical linear drives, the zone where a plurality of cars 1 are present is set to a mechanical drive method, so that not only the safety can be ensured but also the power consumption is reduced and the living space is reduced. It has the advantage of easy connection.

(Other Embodiments) The present invention is not limited to the above-described embodiments of the invention, but can be modified and implemented as follows. That is, it has been explained that the selection between the express zone 11 and the general zone 10 is calculated by the time to the destination floor, but it is obvious that some users do not like the ride comfort and the waiting time in high-speed driving, and the selection of this travel route is necessary. It is also possible to use a call button (not shown).

Further, means for comparing the traveling directions and speeds of the plurality of cars 1 and the destination floor are provided in the express zone 11
The priority order of travel may be switched depending on the time to reach the branch position of the general zone 10.

Furthermore, the express zone 11 and the general zone 10
The selection may be configured so that it can be selected by the instruction of the user of the car. By doing so, it becomes possible to drive according to the taste of the user.
