Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to an elevator installed in an ultra-high-rise building or the like having a building height of several hundred meters to 1,000 meters.

<< Conventional technology >> In a conventional general elevator, an elevator cage is hung with a wire and the wire is hoisted by a hoist.
I was lowering.

Then, in order to reduce the capacity of the hoisting machine required for hoisting the elevator cage, a balance weight is arranged in the elevator shaft so that the weight of the balancing weight is balanced with that of the elevator cage.

<< Problems to be Solved by the Invention >> In the above conventional elevator, since the elevator cage is directly wound in the vertical direction, consideration is given to increasing the winding power capacity or slowing the winding speed. However, the practical use of an elevator with a long transport distance of several hundred to 1,000 meters made it difficult to move the elevator up and down due to the increased weight of the rope.

In addition, as the height of hoisting the cage increases, it becomes necessary to increase the hoisting speed and shorten the number of elevators to shorten the waiting time.
It was also supposed to increase the capacity of the hoisting machine and add an elevator shaft.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an elevator in which a large number of elevator cages are simultaneously moved up and down without using balance weights and the number of elevator shafts is small.

<< Means for Solving the Problem >> In order to achieve the above object, an elevator such as an ultra-high-rise building according to the present invention is provided with a spiral first reaction rail forming a linear motor on the inner surface of an elevator shaft, and further The elevator shaft includes an outer cylinder movably installed along the axial direction of the shaft and an inner cylinder which is housed in the outer cylinder and serves as an elevator cage. The outer cylinder is provided on the outer peripheral surface of the outer cylinder. Having a first locking piece for supporting the first reaction rail on the first reaction rail and a first stator attached to the locking piece, and having a horizontal circular ring-shaped first inner surface of the outer cylinder. A second reaction piece is provided on the outer peripheral surface of the inner cylinder while facing the second reaction rail, and a second stator attached to the second reaction piece. Of the outer cylinder The rotational movement of the inner cylinder is controlled so as to be in reverse phase with the outer cylinder at a constant speed with respect to the rotational movement direction.

<Operation> When the first reaction rail on the inner surface of the elevator shaft and the locking piece mounted on the outer peripheral surface of the outer cylinder are fixed for the first time, the linear induction motor is configured, and the reaction rail corresponds to its secondary side. The stator side corresponds to the primary side, and the moving magnetic field is formed on the stator side. Therefore, the outer cylinder moves upward or downward depending on the rotating direction according to the laying direction of the first reaction rail by the moving magnetic field formed by the fixed piece side. At that time, the second reaction rail has a circular ring shape horizontal to the inner peripheral surface of the outer cylinder, and the second stator constitutes a linear motor together with the second reaction rail. Since the inner cylinder is controlled to rotate at a constant rotation speed in the opposite direction, that is, in the direction opposite to the rotation direction of the outer cylinder, the inner cylinder is supported by the second reaction rail on the inner peripheral surface of the outer cylinder. As a result of the state, the outer cylinder moves up and down according to the vertical direction, but with respect to rotation, it remains stationary with respect to the elevator shaft.

<Example> Hereinafter, a preferred example of the present invention will be described in detail with reference to the drawings.

A schematic configuration is shown in FIG. 1, and an outer cylinder 2 and an inner cylinder 3 are housed inside a cylindrical elevator shaft 1, and the outer cylinder 2 and the inner cylinder 3 can be taken out of the elevator shaft 1. A take-out port is provided at an arbitrary height of the shaft 1, and the take-out port is a moving door 4 at a part of the elevator shaft 1. The outer cylinder 2 is a cylindrical one loosely fitted in the elevator shaft,
The inner cylinder is a cylinder that is loosely fitted in the outer cylinder 2, and the inner cylinder 3 also serves as an elevator cage. The inside of the inner cylinder 3 which also serves as an elevator cage may be divided into upper and lower parts, which is a two-story structure so that a person can ride on the upper side and luggage can be stored on the lower side. A plurality of the outer cylinder 2 and the inner cylinder 3 that are integrated are housed at appropriate intervals in the axial direction of the elevator shaft 1, that is, in the height direction thereof. When the cylinder 3 is taken out from the moving door 4, the moving door 4 is returned to its original position before the outer cylinder 2 and the inner cylinder 3 which come after the cylinder 3 come. For this, another moving door may be prepared in advance and replaced immediately.

A first reaction rail 5 made of carbon steel or the like is provided on the inner peripheral surface of the elevator shaft 1, and the outer peripheral surface of the outer cylinder 2 is intermittently vertically adjusted in accordance with the inclination angle of the first reaction rail 5. A first skip 6 is provided, which is protruded at a distance. A first stator 7 that faces the first reaction rail 5 and forms a moving magnetic field by a three-phase winding is attached to the first skip 6.

In addition, the second reaction rail 8 is formed in a horizontal ring shape on the inner peripheral surface of the outer cylinder 2, which is formed by connecting the inner cylinder 3 to the outer cylinder 2.
It is intended to be loosely fitted in the housing, and only one step is shown in the drawing, but it may be two steps or three steps in the vertical direction.

A second skip 9 is formed so as to project from above so as to be locked to the second reaction rail 8, and a second fixed piece 10 is attached to the second skip 9.

The first reaction rail 5 and the first stator 7 are linear members for rotating the outer cylinder 2 along the first reaction rail 5 formed on the inner peripheral surface of the elevator shaft 1 and moving up and down depending on the rotation direction. It constitutes a motor. The second skip 9 provided on the inner peripheral surface of the outer cylinder 2 and the second stator 10 on the outer peripheral surface of the inner cylinder 3 constitute another linear motor for rotating the inner cylinder 3. .

That is, the outer cylinder 2 is supported on the first reaction rail 5 by the first stator 7, and the inner cylinder 3 is mounted on the second reaction rail 8 on the inner peripheral surface of the outer cylinder 2 by the second stator 10. We support. This is shown in FIG. The linear motor control device composed of the first reaction rail 5 and the first stator 7 is controlled by the linear motor machine room 11 provided at the upper portion of the outer cylinder 2, and the second reaction rail 8 and the second reaction rail 8 are controlled. The so-called second linear motor constituted by the stator 10 is controlled by the linear motor machine room 12 provided above the inner cylinder 3. Then, for safety, the inner cylinder 3 passes from the axis of the inner cylinder 3 to the axis of the outer cylinder 2, and is connected to the outer cylinder 2 by the inner cylinder shaft 13 locked to the upper portion of the outer cylinder 2 by a thrust shaft or the like. It is mechanically suspended to reduce the mechanical and magnetic load applied to the second reaction rail 8 and the second stator 10. Therefore, the second reaction rail 8 and the second stator 12 do not need a magnetic force to levitate the inner cylinder 3, and a torque for rotating the inner cylinder 3 is sufficient. However, it goes without saying that the inner cylinder 3 may be magnetically levitated and supported by the second stator 10 and the second reaction rail 8.

In the linear motor mechanical type 11 and the linear motor mechanical type 12 on the inner cylinder 3 side, the inner cylinder 3 is given a reverse rotation that is the same speed as the rotation speed of the outer cylinder 2. The first stator 7 and the second stator 12 give a moving magnetic field by an inverter or the like,
It suffices to control these inverters just in opposite phase. The difference in speed resulting from the difference in diameter between the outer cylinder 2 and the inner cylinder 3 is controlled by controlling the respective stators 7 and 10 so that the inner cylinder 3 is maintained in a state not rotating with respect to the elevator shaft 1 and operated. To do.

<Effects> As described in detail above, according to the elevator for an ultra-high-rise building or the like according to the present invention, the elevator having the spiral reaction rail formed on the inner surface of the elevator shaft provided on the outer peripheral surface of the outer cylinder is lifted The inner cylinder that also functions as a cage can be moved vertically while rotating the outer cylinder that is supported by the second reaction rail and the second stator. When used as an elevator for high-rise buildings, there is no rope for the elevator cage inside the elevator shaft, and a considerably large amount of power to wind the rope is installed at the apex of the ultra-high-rise building compared to the elevator that winds the elevator cage with conventional ropes. It has the effect of avoiding the disadvantage that this is super On the center of gravity distribution of the case where the high-rise building is also advantageous.

Furthermore, since a large number of outer cylinders and inner cylinders can be arranged inside the elevator shaft while maintaining a certain vertical distance in the height direction, it is not necessary to install multiple elevator shafts. An effect equivalent to driving an elevator is obtained. As a result, it is also advantageous in terms of the area occupied by elevator equipment per floor area of an ultra-high-rise building, and it is also possible to transfer the inner cylinder and outer cylinder taken out in the elevator shaft to other parts as they are. Is.
