Description

Description: TECHNICAL FIELD The present invention relates to a guide rail structure of an elevator apparatus that guides movement of a linear motor elevator cage.

[Conventional technology]

In recent years, in order to increase the carrying amount per unit time and building unit area of building users, a plurality of cages are accommodated in an elevator elevator passage so that they can travel freely.
A linear motor type elevator system has been proposed.

In this elevator system, as shown in FIG. 9, the upper and lower ends of the ascending passage 90 and the descending passage 92 are connected by an upper traverse passage 94 and a lower traverse passage 96 to form a loop shape. Inside the elevator passage 12, multiple cages
18 is circulated and driven by a linear motor.

In such an elevator system, the operation control is simple because the cage 18 moves only in a fixed direction (counterclockwise in FIG. 9). However, since the cage moves only in a certain direction, it takes time until the next cage arrives immediately after passing the cage, and the waiting time before boarding the cage increases accordingly.

To resolve this issue, the floor with the passengers waiting for boarding cage 18 and the closest cage
It is necessary to utilize 18 effectively.

To this end, traverse passages 94 and 96 of the cage 18 must be provided for each floor so that the cage 18 arranged in the elevator passage 12 can move not only in a certain direction but also in the vertical and horizontal directions to home. .

However, for each floor there is a walkway 9 for the cage 18
In order to provide 4, 96, it is necessary to install a guide rail for guiding the cage 18 laterally on each floor.

In order to allow the cage 18 to stably traverse, the guide rail is a pair of transverse members, namely, a suspension guide rail that suspends the upper end of the cage 18 and a support guide rail that supports the lower end of the cage 18. It is configured. Therefore, in order to provide the traverse passage for each floor, it is necessary to install two traverse guide rails, respectively, which is disadvantageous in that the construction cost increases.

[Problems to be solved by the invention]

In view of the above facts, an object of the present invention is to provide a guide rail structure capable of reducing the number of guide rails that guide the lateral movement of the cage.

[Means for solving the problem]

The present invention is a guide rail structure which is disposed in a passage for an elevator cage and which guides the elevator cage. The guide rail structure is extended in a vertical direction of the passage for the elevator cage, and a mounting portion is rotatable in a transverse direction of the elevator cage. And a guide rail for raising and lowering which is sandwiched by the rollers to guide the elevator cage, and a part of the guide rail for raising and lowering, which can be rotated vertically or horizontally while being sandwiched by the rollers. A rail, a rotating means for rotating the rotary rail, and a horizontal arrangement of the rotary rail, the horizontal rail being connected, the roller being sandwiched by the rollers, and the elevator cage being guided horizontally. A guide rail for traversing, and the guide rail for traverse, when the elevator cage traverses in the horizontal direction, Is clamped to the roller upper and attached to the lower portion of the cage is characterized in that it is arranged so that the supporting and for the lower hanging.

[Action]

According to the present invention, the elevator cage is guided in the vertical direction by the rollers sandwiching the vertically moving guide rails arranged in the elevator passage.

On the other hand, the rotary rail constitutes a part of the elevating guide rail, and is rotatable in the vertical direction or the horizontal direction. Further, the mounting portion of the roller is rotatable in the direction traversing the elevator car. Therefore, when the rotating rail is sandwiched between the rollers and rotated by the rotating means, the roller also rotates integrally with the rotating rail.

Then, when the rotary rail becomes horizontal, it is connected to the horizontally arranged guide rails, and the rollers hold the transverse guide rails to guide the elevator cage in the horizontal direction.

Further, a pair of traverse guide rails are provided above and below the traverse oil passage so that when the elevator cage traverses in the horizontal direction, the traversing guide rails are sandwiched by rollers attached to the upper and lower portions of the elevator cage.

Thus, for example, the traverse guide rail that functions as a suspension when the elevator cage horizontally traverses on the first floor functions as a support when the elevator cage horizontally traverses on the second floor. Therefore, the number of members of the traverse guide rail can be reduced.

As described above, in this embodiment, the vertical spacing of the traverse guide rails 22 is set to be the same as the axial spacing L of the rollers 46 attached to the upper and lower ends of the cage 18, respectively.
The two guide rails 22 for traverse can be used both for supporting and suspending the cage 18, and the number of the guide rails 22 for traverse installed can be reduced.

In addition, the transverse guide rails 21 are not provided between the adjacent rotary rails 21, but the cages 18 are connected by connecting the rotary rails 21 to each other.
The horizontal elevator passage 12
The arrangement space can be reduced.

In this embodiment, the elevating linear motor 54 is of a synchronous type and is composed of the electromagnet 50 and the permanent magnet 52, but the elevating linear motor 54 is not limited to this. For example, an induction type linear motor using an iron plate coated with aluminum may be used instead of the permanent magnet 52, or a synchronous type linear motor using an electromagnet may be used instead of the permanent magnet 52.

Further, the driving device of the rotating rail 21 is not limited to a linear motor, but may be a normal motor or a hydraulic device.
