Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an operation path of a car driven by a linear motor without using a main rope.

[Prior Art] Conventionally, as is well known, in an elevator, a car and a counterweight are connected by a main rope, and this is driven by a hoist installed in a machine room to raise and lower the car. .
On the other hand, without using a hoisting machine, counterweight, main rope, etc.,
An elevator has been proposed in which a car is driven by a linear motor.

FIG. 6 is a vertical cross-sectional view of a service route showing a conventional elevator without a main rope.

In the figure, (1) and (2) are vertical paths arranged in parallel, and (3)
(4) is a horizontal road that connects the upper and lower ends of the vertical roads (1) and (2). The vertical roads (1) and (2) and the horizontal roads (3) and (4)
A service route (5) that circulates in is formed. (6) is a floor, and (7) to (9) are a plurality of cars housed in the operation path (5) and driven by a linear motor (the arrangement of the linear motor will be described later).

The conventional elevator without a main rope is configured as described above, and a plurality of cars (7) to (9) are driven by a linear motor to circulate in a certain direction in the operation path (5) to drive and call. Stop on the floor (6) with.

[Problems to be Solved by the Invention] In the conventional elevator without main rope as described above, the operation route (5) including the vertical routes (1) and (2) and the horizontal routes (3) and (4) is used for the car (7). Since the car (7) is circulated, for example, when the car (7) stops at the floor (5) and passengers are getting on and off, another car (8) rises, Not only does the stopped car (7) get in the way, the car (8) has to stop somewhere along the vertical path (1) and wait for the car (7) to depart, but this stop will be delayed. There is a problem in that it becomes a hindrance to the car (9) coming from the car, which significantly deteriorates the operation efficiency.

The present invention has been made to solve the above-mentioned problems. Even if the car stops on the floor, the operation of the elevator without the main rope is made possible to continue the operation without obstructing the traveling of the car that comes later. The purpose is to provide a path.

[Means for Solving the Problems] The operation route of the elevator without main rope according to the present invention is provided with a space for retreating a car that also serves as a landing, on the side of the floor position of the vertical route.

Further, an operation route of an elevator without a main rope according to another invention of the present invention is one in which a space for evacuation of a car that also serves as a landing is provided on the side of a plurality of horizontal roads connecting vertical roads at a floor position. Is.

[Operation] In the present invention and another invention of the present invention, since the space for retreating the car is provided on the vertical path or the horizontal path, the other car can freely run when the car enters the space.

[Embodiment] FIGS. 1 to 4 are views showing an embodiment of the present invention. FIG. 1 is a longitudinal sectional view of an operation route, FIG. 2 is an enlarged sectional view taken along line II-II of FIG. FIG. 3 is a perspective view inside the vertical path, and FIG. 4 is a perspective view of FIG.
FIG. 3 is an enlarged cross-sectional view taken along line III-III, in which parts similar to those of the conventional device are designated by the same reference numerals.

In the figure, (11) is a guide rail that is fixed to the side walls of the vertical paths (1) and (2) and guides up and down of the car (7) (same for other cars), and (12) is both sides of the guide rail (11). Primary coil of the linear motor arranged along the line (13) are secondary conductors of the linear motor that are provided on both sides of the car (7) and face the secondary conductors (12), and (14) is the car (7) A brake that is provided on the vehicle and applies a brake to the car (7) by pressing the guide rail (11). The brake (14) and the guide rail (1)
Guide shoe (not shown) guided to 1) moves forward
It is configured to be retractable. (15) is a car door that opens and closes the entrance and exit of the car (7), (16) is a wheel installed on the lower surface of the car (7), and (17) is the floor position side of the vertical path (1) (2) Is a space for car evacuation that is located on one side and communicates with the vertical paths (1) and (2), and a primary coil (12) is arranged on the side wall thereof.
Rails (18) on the floor that guide the wheels (16) of the car (7)
Has been laid. (19) is a landing door that opens and closes the entrance of the evacuation space. Note that the horizontal paths (3) and (4) are similarly provided with the primary coil (12) and the rail (18).

In the operation route of the elevator without the main rope configured as described above, the primary coil (12) is sequentially energized to generate an electromagnetic force between the primary conductor (12) and the secondary conductor (13), and the car (7) The items (9) to (9) circulate in the operation route (5) as in the conventional device. When the car (7) stops on the floor with the evacuation space (17), the car (7) is driven in the horizontal direction and moves in the evacuation space (17) guided by the rail (18) to stop. Then, the car door (15) and the landing door (19) are opened to allow passengers to get on and off. With this, if the following car (8) responds to a call above the floor with the evacuation space (17), it is possible to skip the preceding car (7) and service the upper floor, thus improving operational efficiency. Will be greatly improved.

FIG. 5 is a perspective view of an operation road showing another embodiment of the present invention.

In the figure, (21) and (22) are horizontal roads that connect the vertical roads (1) and (2) at an intermediate floor position, and (23) are horizontal roads (3) that are arranged beside the horizontal road (3). ), A space for evacuation that communicates with ()
4) (25) is a retreat space also provided on the horizontal road (21), (26) and (27) are retreat spaces provided on the horizontal road (22), and (28) is a retreat space (4) ), The landing door (19) is provided in each of the evacuation spaces (23) to (28). In addition, horizontal road (3)
(4) A turntable, for example, is installed in the part of the retreat spaces (23) to (28) of (21) and (22), and the moving direction is 90 degrees.
It is rotated so that the car door (15) and the landing door (19) face each other.

In this embodiment, not only the horizontal roads (3) and (4) but also the intermediate horizontal roads (21) and (22) are circulated through the cars (7) to (9). Then, if the car (7) is in the escape space (24), the other cars (8) and (9) can run freely without the car (7).

The retreat spaces (23) to (28) may be divided into an ascending car and a descending car.

Further, although the cars (7) to (9) are supposed to be turned by the turntable, they can be turned by themselves.

[Effects of the Invention] As described above, according to the present invention and another invention of the present invention, a space for evacuation of a car that also serves as a landing is provided on a vertical path or a horizontal path of an operation path in which a car of an elevator driven by a linear motor circulates. So, if the car enters the above space,
Other cars can run freely, and it is possible to eliminate wasteful stoppage of the car due to waiting for passage, which has the effect of significantly improving operating efficiency.
