JPH03152078A - Cage direct drive type elevator - Google Patents

Abstract

PURPOSE:To freely carry out the vertical motion, the horizontal motion of a cage or the combination thereof without restricting the elevating height, by providing such a cage direct drive type elevator in which drive coils for linear motors are provided on both side surfaces of each cage, and secondary plates are laid on the wall surfaces of a passage. CONSTITUTION:During vertical travel of each cage 1, a.c. current is applied to vertical drive coils 3 which therefore generate an advancing magnetic field so as to induce an induction current on the secondary plate 5 side to generate a vertical thrust force by which the cage 1 is elevated. Then, horizontal drive coils 4 on the cage 1 are energized so as to similarly drive the same in a horizontal direction. With this arrangement, an extremely smooth transition from the vertical movement to the horizontal movement or vice versa can be made. Further, if the cage passage 2 is curved, the coils 3, 4 are simultaneously energized so as to produce a resultant force in an inclined direction between vertical and horizontal thrust forces. Accordingly, the cage 1 can travel through the curved passage 2C with its floor surface being always horizontally held.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an elevator of the type in which a carrier is directly driven without using wire lobes.

<Prior Art> Conventional elevators are driven by wire lobes. Therefore, the following problems arise.

<Problems to be solved by the present invention> Since lobes are used for lifting, the lift height is large (
The larger the lobe, the larger the diameter and weight of the lobe, requiring more powerful driving power, and there was a limit to the speed at which it could ascend.

Furthermore, since lobes are used, multiple carriers cannot be moved freely within one carrier path.

Furthermore, it has been impossible to adopt a structure that combines vertical movement and horizontal movement.

However, in the future, the height of skyscrapers will continue to increase, and the development of deep underground structures as well as structures extending above ground will become more active.

In such cases, the need for high-speed, large-volume, three-dimensional (a combination of horizontal and vertical) transportation will only increase.

<Objective of the present invention> The present invention was made in order to solve such problems, and an object of the present invention is to provide the following carrier direct drive elevator.

<A> Elevator that can move without being subject to any restrictions on rising and descending heights <Exit> Elevator that can freely move multiple carriers in the same passage <C> Not only vertical movement (horizontal movement and An elevator capable of moving a combination of these <Means for solving the problem> In other words, the present invention comprises a drive coil for a linear motor consisting of a carrier and a passage in which a secondary plate is installed, and the drive coil is connected to the carrier. On the side, the secondary plates are each installed on the wall of the passage, and the elevator is directly driven by the carriage.

The present invention also provides a direct drive for the carriage, which is composed of a passage having a drive coil for a linear motor and a carriage on which a secondary plate is installed, the drive coil being installed on the wall of the passage, and the secondary plate being installed on the side of the carriage. It is a type elevator.

<Description of the present invention> The present invention will be explained in detail below.

<A> The carrier 1 is a normal container, and all containers such as those carrying people and cargo are subject to the present invention.

It is preferable that the entrances and exits of this carrier 1 are not opened only in one direction like conventional general carriers, but are installed on four sides depending on the approach position of people and objects.

Furthermore, considering the ejection and reception of articles, it is also possible to adopt a structure in which a door is provided on the floor or ceiling and the door is opened and closed.

<Exit> Passageway A building or structure is provided with a passageway 2 through which the carrier 1 moves.

In the example of the drawing, the passage 2 is assumed to be in a skyscraper or a super high-rise building with a height of around 1,000 meters, but it can of course be used in a normal building or a structure installed underground. .

This passage 2 is not only a vertical passage 2v installed in the vertical direction like a conventional elevator (but also a horizontal passage 2H (Fig. 5) connected to the vertical passage 2v), or a curved passage 2C (
It is characterized by the fact that it also targets the following: (Fig. 3).

<C> Linear motor mechanism A drive coil and a secondary plate constituting the linear motor are arranged on the side surface of the carrier 1 and the wall surface of the passage 2 with a slight gap between them.

The secondary plate is made of a conductive material such as aluminum, in which eddy currents easily flow due to electromagnetic induction.

If the driving coil is provided on the side, front and rear surfaces of the carrier 1, the secondary plate will be provided on the wall of the passage 2 with a slight gap from the driving coil.

If the driving coil is provided on the wall of the passageway 2, the secondary plate will be provided on the side of the carrier 1.

The installation will be explained below according to the position.

<2> When installing the coil on the carrier In Fig. 1.2, the case where the drive coil is attached to the side of the carrier 1 will be explained.

For example, a vertical drive coil 3 is installed on the upper side of the carrier 1.

On the other hand, a horizontal drive coil 4 is installed at the lower part of the side surface of the carrier 1.

In this case, a secondary plate 5 is laid on the wall of the passage 2.

As mentioned above, the passage 2 includes a vertical passage 2V and a horizontal passage 2V.
H, or because there is a curved passage 2C, the secondary plate 5
are also laid on the wall surface according to the direction and shape of the passageway 2.

By laying the secondary plate 5 on a wall surface (instead of laying it on the floor surface), it becomes possible to lay it continuously on a vertical, horizontal, or curved surface.

<E> When attaching the coil to the passage In FIG. 4, the horizontal drive coil 4 is attached to the wall of the passage 2.

On the other hand, the vertical drive coil 3 is attached to the wall of the elevating passage.

In this case, a secondary plate 5 is attached to the side surface of the carrier 1.

The floor above the lift passage is configured to be openable and closable.

Then, by inputting signals to each drive coil and the floor opening/closing mechanism, the objects to be transported in the carrier 1 can be sorted horizontally and vertically.

Sorting into vertical elevator passages is performed as follows.

1) Stopping the horizontal drive coil, 2) Activating the vertical drive coil, supporting the carrier, 3) Opening the floor, 4) Lowering the carrier. Of course, in the embodiment shown in Fig. 4, the drive coil and secondary plate are It is also possible to arrange them in opposite positions.

<Action of the present invention> Next, the operation of the present invention will be explained.

<A> In order to move the vertically moving carrier 1 in the vertical direction, a traveling magnetic field is generated in the coil by passing an alternating current through the vertically driving coil 3.

Then, an induced current is generated on the secondary plate 5 side, and according to Fleming's left hand rule, the vertical thrust causes the carrier 1 to
will rise and fall.

In this case, the operation of the horizontal drive coil 4 is stopped.

Exit> The signal is input to the horizontal drive coil 4 of the horizontal moving carrier 1, and the horizontal drive is similarly performed.

In this case, the operation of the vertical drive coil 3 is stopped.

In this way, vertical to horizontal movement, or vice versa, can be performed very smoothly.

(c) Movement in a curved path (FIG. 3) When the carrier path 2 is formed in a curved line, the vertical drive coil 3 and the horizontal drive coil 4 are operated at the same time.

Then, a diagonal resultant force is generated by combining the vertical thrust and the horizontal thrust.

For this reason, the carrier 1 always maintains the floor level horizontally.
To move and travel smoothly on a curved passage 2C.

<2> The loading and unloading of passengers and the loading and unloading of goods is carried out by opening and closing the door, floor, and ceiling of the carrier 1 at positions corresponding to the aisle and floor positions.

Therefore, the secondary plate 5 to be installed on the wall surface of the carrier passageway 2 should be installed in consideration of the arrangement and direction of the approach path for people and goods.

<Other Embodiments> Although the linear induction motor of the type that combines a drive coil and a secondary plate has been described above as an example, it is of course possible to employ other types of linear induction motors that are conventionally known.

<Effects of the Present Invention> Since the present invention has the above-described configuration, the following effects can be achieved.

<B> The carrier can be moved without being restricted by height.

<Exit> Multiple carriers can be operated simultaneously on the same path.

Therefore, the floor space of the building can be used more effectively than in the conventional structure of one cart in the aisle.

<C> Not only vertical movement but also horizontal movement and movement in combinations thereof are possible.

<2> It is also possible to connect the carrier passages in an annular manner, and a circulation type elevator configuration is also possible.

<E> If a coil is installed on the carrier side, each carrier can move and stop freely within a range that does not collide with the carriers in front and behind.

Since a linear motor is formed by the wall surface of the passageway and the side surface of the carrier, the carrier can be kept vertical at all times even in curved passages, that is, the floor of the carrier can be kept horizontal at all times when traveling.
