[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator mainly installed in a high-rise building, and relates to an elevator for mass transportation corresponding to an increase or decrease in the number of users.

[0002]

2. Description of the Related Art Conventionally, in a high-rise building or a skyscraper, a high-speed elevator and a low-speed elevator are separately provided as a conventional example or a low-rise floor is stopped as a conventional example in order to transport users to the upper part at high speed. It is known that an elevator for high floors that stops sequentially from a predetermined floor or higher and an elevator for low floors that stops only on low floors are provided without doing so.

[0003]

However, in a high-rise building equipped with an elevator as in the above-mentioned conventional example, the proportion of the elevator shaft in the floor becomes large, and the floor area cannot be effectively used. was there.

Further, the mass transportation method using the high-speed elevator is naturally limited because the elevator speed is limited. On the other hand, if the elevator is divided into high-rise and low-rise elevators, the high-speed elevator cannot stop. When a person on the middle floor goes to a higher floor, they have to change from a low-rise elevator to a high-rise elevator, and to eliminate the inconvenience, a low-speed elevator that stops on all floors is added. There was a problem that I had to do it.

As described above, conventional elevators for high-rise buildings have problems to be solved in terms of effective use of floor area and transportation. The present invention has been made in view of the above problems, and an object of the present invention is to provide an elevator that can reduce the number of elevator shafts to effectively utilize a floor area and can be transported in large quantities.

[0006]

The gist of the present invention to solve the above problems and achieve the above objects is to provide a parent basket and a slave basket on one elevator shaft in a freely connectable manner.

Further, a locking tool is provided on the lower surface of the master basket, and a deflecting wheel having a locking device for engaging with the locking tool is provided on the upper surface of the slave cage.

[0008]

According to the elevator of the present invention, it is possible to carry out mass transportation and reduce the number of elevator shafts. Further, a lock device is provided on the deflecting wheel of the child cage so that the parent and child cages can be connected or can be moved up and down separately.

[0009]

Next, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a vertical sectional view when the elevator according to the present invention is applied to a high-rise building or the like.

In this elevator A, a parent cage 1 and a child cage 2 are connected in a tandem type in one elevator shaft, and are connectable so that they can be disconnected.

An end of a rope 1a for raising and lowering is connected to the main basket 1, the rope 1a is wound around a winding machine 3 and a deflecting wheel 4, and the other end is connected to a counterweight 5. ing.

On the other hand, the child cage 2 is hung by the deflecting wheels 4 and 4 provided on the lower end surface of the parent cage 1, and the rope 2 for raising and lowering is used.
A has one end connected to a child cage and the other end connected to the upper frame of the building and wound.

In the middle of the rope 2a, as shown in FIG. 2, the baffle wheel 4, provided on the upper frame of the building, is provided.
4 and the deflecting wheel 4 provided on the upper end surface of the linear motor 6
It is wound around a and 4a. The linear motor 6 moves up and down along guide rails 7 laid vertically.

Since the rope 2a is wound in this manner, the raising / lowering amount 6a of the sub cage 2 is, for example, about 1/4 of the feeding amount 2f of the rope 2a, as shown in the figure. Naturally, it is also possible to make the lifting amount 6a half of the feeding amount 2f or the like depending on how the rope is hung.

As a method of connecting the main basket 1 and the sub basket 2, for example, as shown in FIG. 3, a frame 1b attached to the lower end face of the main basket 1 is provided with protrusions protruding from the left and right side surfaces thereof. The connecting rods 1c and 1d are driven by an electric motor 1e so as to be retractable by rack and pinion means.

On the upper end surface of the sub basket 2, a coil spring 2b is provided in a frame body 2e provided on both left and right sides, and a tip portion is constantly urged inward by the coil spring 2b from a side surface of the frame body 2e. Engaging plates 2c and 2d are provided. The tip ends of the engagement plates 2c and 2d are arranged so as to engage with the engagement rods 1c and 1d.

According to this connecting device, the child cage 2 is attached to the rope 2
When it is lifted by a, the tip portions of the engaging plates 2c, 2d come into contact with the tip portions of the engaging rods 1c, 1d, and the respective tip portions have slanted slopes. The tip ends of the engaging plates 2c and 2d are recessed into the frame body against the elastic force of the coil spring 2b while slidingly contacting each other on the inclined surface.

Further, the child cage 2 is lifted up to finish the slidable contact of the slopes of the respective tip portions, and the engaging plates 2c and 2d are returned to the inner side by the coil spring 2b so as to appear and disappear. When is lowered, the upper surfaces of the engaging rods 1c and 1d and the lower surfaces of the engaging plates 2c and 2d abut and engage with each other, and the parent cage 1 and the child cage 2 are brought into a connected state.

When releasing the connection state,
The child cage 2 is raised by the rope 2a, and the engaging rods 1c, 1
The upper surface of d is separated from the lower surfaces of the engaging plates 2c and 2d to release the engagement, and then the electric motor 1e is driven to retract the engaging rods 1c and 1d into the frame 1b.

Next, the rope 2a is paid out by the linear motor 6 to lower the cage 2. Although the tip portions of the engaging plates 2c and 2d are in a state of protruding and retracting from the frame, the engaging rod 1
Since c and 1d do not project from the side surface by sinking into the frame 1b, they do not abut. In this way, the parent basket 1 and the child basket 2 can be operated separately.

Not only the connecting device as described above, but also the main basket 1 and the sub basket 2 may be provided with a connector for a freight car, an electric train, or the like.

Further, in the hoisting machine 3, the suspension load is approximately doubled by providing the disc brake 3a on the drive shaft in preparation for the case where the master basket 1 and the slave basket 2 are connected and moved up and down. Be prepared to control enough even when it becomes.

By providing a plurality of elevator cages having the parent cage 1 and the child cage 2 on one skyscraper in a skyscraper, various operations can be performed by controlling the elevator operation by a computer system. It will be possible.

For example, when there are many users in the morning and evening, the parent cage 1 and the child cage 2 are connected by the connecting device to operate as a double deck elevator.

The hoisting machine 3 is used for raising and lowering the main cage 1 and the slave cage 2, and the linear motor 6 stops the energization to use the counterweight of the rope 2a for the slave cage 2.

As a result, a large number of users can be transported on the double deck by the parent cage 1 and the child cage 2, and the transportation efficiency is improved.

On the other hand, when there are few users, it is not necessary to use a double deck, so the parent basket 1 or the child basket 2 can be used.
Run only.

In this case, when the parent cage 1 is operated, the child cage 2 is evacuated to the evacuation floor 8 at the bottom of the elevator shaft. Also, when operating the child cage 2, the parent cage 1
Is fixedly stopped on the upper part of the elevator shaft, and the linear cage 6 drives the child cage 2.

In addition, the parent cage 1 and the child cage 2 can be operated at the same time so that the parent cage 1 is for the upper floors and the child cage 2 is for the lower floors. In this case, which floor is the transfer floor can be set arbitrarily. Therefore, the transfer floors of the plurality of elevator shafts may be different from each other or may be the same, so that the convenience of use can be improved.

The linear motor 6 for winding up the ropes of the sub basket 2 moves up and down together with the deflecting wheels 4 and 4 provided on the lower end surface of the main basket 1, so that the main basket 1 and the sub basket 1 Up and down control will be performed along the guide rails 7 so as to match the difference in operation between the two.

In this way, the two elevators are simultaneously moved up and down separately on one elevator shaft, and the operating efficiency is improved.

[0032]

As described above, in the elevator of the present invention, the parent cage and the child cage are provided on one elevator shaft in a freely connectable manner. For transportation, one of the parent basket and the child basket can be operated independently to go directly to the floor to be used for convenience and small energy, and the parent basket for higher floors, and There is an excellent effect that various settings can be made, such as operating the child cages for lower floors at the same time to improve operation efficiency.

Further, as compared with the conventional elevator system, since two cages are provided on one elevator shaft, there is an excellent effect that the floor area of the building can be effectively utilized.

Further, a locking tool is provided on the lower surface of the parent basket,
Since it was decided that a baffle wheel having a locking device that engages with the locking device was provided on the upper surface of the sub cage, it is possible to use the double cage elevator by arbitrarily connecting the main cage and the sub cage. It has an excellent effect that it can be done.
