Abstract

PURPOSE: To optionally move a passenger car along a wall surface by arranging a normally conductive coil in a lattice form vertically and horizontally along the wall surface, setting a superconductive magnet in the passenger car, and changing the polarity of the generated magnetic field vertically and horizontally. CONSTITUTION: Normally conductive coils 13 are set in a lattice form vertically and horizontally on two opposed parallel wall surfaces of a hoistway, and superconductive magnets 12 are set on both surfaces of a passenger car 11 opposed thereto in the same lattice form to constitute a linear motor by the both. The polarity and magnetic flux density of the magnetic field generated by each of the normally conductive coils 13 are controlled by a control device 114, whereby the passenger car 11 is moved vertically or horizontally, or in an optional direction in the state separated from the wall surfaces. Thus, an excellent elevator device can be realized.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an elevator device that is movable in any direction on a wall surface.

BACKGROUND OF THE INVENTION Traditionally, elevator systems have been designed for vertical movement. A conventional elevator system will be explained below.

FIG. 4 shows the configuration of a conventional elevator system, where 1 is a seat, 2 is a rope, 3 is a pulley, and 4 is a motor.

The operation of the elevator system configured as described above will be described below with reference to the drawings.

The seat 1 is connected to a rope 2, and the rope 2 is connected to a motor 4 via a pulley 3. The direction of rotation of this motor 4 is controlled to move the seat up and down in the vertical direction.

Problems to be Solved by the Invention However, the conventional structure described above has a drawback in that the direction of movement of the car is limited to the vertical direction and cannot be moved in any other direction.

The present invention solves the above-mentioned conventional problems, and aims to provide an elevator device that can move along a wall surface not only in a vertical direction but also in a horizontal or diagonal direction. .

Means for Solving the Problems To achieve this objective, the elevator system of the present invention comprises:
A car with normal conducting coils arranged in a grid pattern in the vertical and horizontal directions of the wall and superconducting magnets installed on the wall side, and vertical and horizontal targets arranged on the wall depending on the direction in which the car is moved. It has a configuration including a control device that controls the polarity of the magnetic field generated by the conductive coil.

Function: With this configuration, a linear motor is constructed by arranging normal conducting coils in a lattice pattern on the wall and superconducting magnets installed at the ride legs, and a method of changing the polarity of the magnetic field generated by the normal conducting coils placed on the wall. By changing it, you can move it in any direction along the wall.

EXAMPLE An example of the present invention will be described below with reference to the drawings.

FIG. 1 shows the configuration of an elevator system according to an embodiment of the present invention, FIG. 1A is a top view thereof, and FIG. 2B is a front view thereof. In FIG. 1, reference numeral 11 denotes a car, and a superconducting magnet 12 is formed on the surface facing the wall surface. 1
3 is a normal conducting coil provided on the wall surface, and 14 is a control device for controlling the polarity of the magnetic field generated by the normal conducting coil 13.

The operation of this embodiment configured as above will be described below.

The elevator system of this embodiment moves a passenger seat between two opposing parallel wall surfaces. Normal conducting coils 13 are installed on the wall surface in a grid pattern in the vertical and horizontal directions, and the polarity and magnetic flux density of the magnetic field generated by each normal conducting coil 13 are controlled by a control device 14, respectively.

Superconducting magnets are installed on each of the two walls of the car.

FIG. 2 is a view of the wall surface viewed from the normal direction, and normal conducting coils are arranged on the surface of the wall surface in a grid pattern in the vertical and horizontal directions. First, in order to move in the vertical direction, as shown in FIG. 2, the polarity of the normally conducting coil 13 is changed to form a linear motor in the vertical direction of the wall surface, and a propulsion force is applied in the vertical direction. At this time, the two opposing wall surfaces change the polarity in the same way, and the range in which the polarity of the normally conducting coil 13 is changed is limited to the width of the heel 11 so that the heel does not move in the lateral direction of the wall surface.

The force acting on the seat 11 in the normal direction of the wall surface which the seat 11 receives from the two opposing wall surfaces is still the same, and the seat 11 can move vertically away from the wall surface.

Similarly to FIG. 2, FIG. 3 is a view of the wall surface viewed from the normal direction, and the normal conducting coils 13 are arranged in a grid pattern in the vertical and horizontal directions on the surface of the wall surface. In order to move in the horizontal direction, as shown in FIG. 3, the polarity of the normally conducting coil 13 is changed to form a linear motor in the horizontal direction of the wall surface to provide a horizontal propulsion force. At this time, the two opposing walls change their polarity in the same way, and the normal conducting coil 13
The range in which the polarity of is changed is limited to the height of the power and 11. Further, the forces acting in the normal direction of the wall surfaces that the rider heel 11 receives from the two opposing wall surfaces are the same, and the rider heel 11 can move in the horizontal direction while being separated from the wall surface.

Note that if the normally conducting coil 13 is controlled simultaneously in the vertical and horizontal directions, it is also possible to move the seat heel 11 in an oblique direction.

As described above, according to this embodiment, the normal conducting coils 13 are arranged in a grid pattern on two opposing walls, and the superconducting magnets 12 are installed in the seats 11, so that the seats 11 are magnetically levitated and linear The motor allows it to move not only vertically but also horizontally.

Effects of the Invention The present invention arranges normal conducting coils in a grid pattern along the wall surface in the vertical and horizontal directions, installs superconducting magnets in the seats, and uses a control circuit to control changes in the polarity of the magnetic field generated by the normal conducting coils. By controlling the vertical and horizontal directions, it is possible to realize an excellent elevator system that can move in any direction on the wall surface.
