Description

[Detailed Description of the Invention] The present invention relates to a rail branching and switching device installed at a rail branching section of a suspended monorail or the like.

To explain a conventional example of a rail branching and switching device for a suspended monorail, as shown in Figs. 1 to 3, the rail structure is such that a space a is provided for suspending a passenger car (not shown), and bogies are placed on the left and right sides of the rail. A pair of running surfaces b, b for running side running wheels (not shown), and a pair of guide surfaces c, c for guiding guide wheels (not shown) on the bogie side to prevent lateral vibration. Main rail 1 having this rail structure
At the center of the rail branch part where the branch rail 10a and the direct rail 10b are arranged in series, there is a movable rail 1 for switching that is operated to alternately switch between the branch rail 10a side and the direct rail 10b side by turning. are arranged by a drive shaft 4. Further, a tip rail 2 is pivotally supported at the tip of the movable side of the movable rail 1 via a vertical shaft 3 so as to be movable in a horizontal angle, and as the movable rail 1 is switched, the tip rail 2 guides the outside of the through rail 10b side at the branching part. A branching guide angle α that corresponds to the side surface 5c and becomes a guiding side toward the branching rail 10a side.
and the outer guide side surface 6 on the side of the branch rail 10a.
c, the main rail 1 is rotated by the direct guide angle β which becomes the guide side toward the direct rail 10b side, and the movable rail 1 and the tip rail 2 rotate the main rail 1.
0, the branch rail 10a, and the direct rail 10b, the structure of the rail branching and switching device is such that it can perform branch running (see FIG. 2) and direct running (see FIG. 3).

However, in the conventional switching device, the fourth
In order to switch from the branch running posture between the main rail 10 and the branch rail 10a shown in the figure to straight running,
When the movable rail 1 is rotated to the left (counterclockwise) about the drive shaft 4 by a drive device not shown, the vertical axis 3 between the movable rail 1 and the tip rail 2 is rotated.
Since a moderate rotational resistance is provided in the portion, after the tip rail 2 is similarly turned with a branching guide angle α with respect to the movable rail 1, the tip rail 2 is rotated as shown in FIG. The sharp tip 2a (see FIG. 7B) is the outer guide side surface 6c of the branch rail 10a.
, the movable rail 1 is further rotated, and the tip rail 2 is rotated to the through-guiding angle β and comes to be in contact with the outer guiding side surface 6c, so that the movable rail 1 is rotated to the through-travel posture as shown in FIG. At the same time, as shown in FIGS. 6 to 4, the movable rail 1
Similarly, when turning right to switch to branch travel, the sharp tip 2a of the tip rail 2 is connected to the direct rail 1.
Due to the collision with the outer guide surface 5c on the 0b side, portions A (see FIGS. 4 and 6) of the outer guide surface 5c on the direct rail 10b side and the outer guide surface 6c on the branch rail 10a side are significantly damaged by the collision. The drawback is that it also generates noise.

Therefore, in the past, rubber was stretched over the A section to cushion the impact and reduce noise, but as mentioned above, the tip of the tip rail 1 was formed sharply to allow the guide wheel to move smoothly. Therefore, there is a disadvantage that the rubber in the A part is easily damaged and the troublesome work of replacing the rubber is required.

This proposal is an idea to solve the above-mentioned drawbacks of conventional rail branching and switching devices, and the main rail is connected to the branch rail side at the center of the rail branch where the main rail is branched into the branch rail side and the direct rail side. A movable rail that is operated to switch between the direct rail side and the direct rail side is provided, and the movable side tip of the movable rail is provided with a tip that is rotated to a branch guide angle to the branch rail side and a direct guide angle to the direct rail side. In a rail branching and switching device equipped with a rail, the tip rail is adsorbed to an outer guide surface on the through rail side and an outer guide surface on the branch rail side, with which the tip end of the tip rail comes into contact. The feature is that each end rail is equipped with a magnet that can automatically change the horizontal angle.

The present invention has the above-mentioned configuration, in which the movable rail disposed at the center of the rail branch is rotated and switched, and the end rail extending from the movable end of the movable rail is connected to the outside of the direct rail side. It is possible to switch between a branching running posture toward the branching rail side in which the tip rail is along the guide side surface and a direct running posture toward the direct rail side in which the tip rail is along the outer guiding side surface of the branching rail side. In either case, the tip of the tip rail is attracted and held by the magnet to the outer guide side surface, and the guiding performance and reliability of the tip rail are significantly improved. When the rail separates from the outer guide side, the tip of the tip rail, which is attracted by the magnet, is moved slowly and the horizontal angle of the tip rail with respect to the movable rail is automatically changed. Collision of the tip end of the tip rail can be prevented and noise generation can be prevented, and damage to the outer guide side surfaces on the through rail side and the branch rail side is significantly reduced, and turning performance and reliability are significantly improved.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. An embodiment of the present invention is shown in FIGS. 7 to 10. In FIGS. 8 to 10, 10 is the main rail before branching, and 10a is the branch that is switched and connected to the main rail 10. The rail 10b is a direct rail that is switched and connected to the main rail 10, and the main rail 10, the branch rail 10a, and the direct rail 10b are arranged on the left and right sides with an interval a, respectively, as shown in FIG. 7A. It has a configuration including a pair of running surfaces b, b and a pair of guide surfaces c, c, and furthermore, a first
As shown in Figures 0, 8, and 9, the movable rail 1 is operated to switch between the branch rail 10a side and the direct rail 10b side by turning in a horizontal plane with the drive shaft 4 as the turning center by a switching drive device (not shown). established,
The base side of the tip rail 2 is pivotally connected to the tip of the movable side of the movable rail 1 via the vertical shaft 3, and the tip rail 2 of the movable side of the movable rail 1 is extended so as to be horizontally movable in a horizontal plane. For example, when the movable rail 1 is turned to the right (clockwise), the tip rail 2 is turned to the branch rail 10a side or the direct rail 10b. is in contact with the outer guide side surface 5c on the direct rail 10b side, and the tip rail 2 has a branching guide angle α toward the branch rail 10a side with respect to the movable rail 1, and the tip rail 2 and the movable rail 1 are connected to the main rail 10. One guiding side surface between the branching rails 10a forms a running surface, and as shown in the figure, the branching running posture is achieved. Also, when the movable rail 1 is switched to left turn (counterclockwise), the second As shown in FIG. 10, the tip rail 2 is placed along the outer guide side surface 6c on the side of the branch rail 10a, and the tip rail 2 forms a branch guide angle β toward the direct rail 10a with respect to the movable rail 1. The rail 2 and the movable rail 1 are connected to the main rail 10 and the direct rail 10b.
As shown in the figure, the structure is such that one guide side surface and the running surface are formed in between, and the vehicle is in a direct running position as shown in the figure.

Furthermore, in this embodiment, magnets 7 are respectively disposed on the outer guide side surface 5c of the direct rail 10b and the outer guide side surface 6c of the branch rail 10a, which the tip end of the tip rail 2 comes into contact with. The sharply formed tip end portion 2a of the tip rail 2 that is in contact with the outer guide side surface 5c or 6c is attracted and held by the suction force of the magnet 7.

Further, the magnet 7 is disposed below the outer guide surfaces 5c and 6c as shown in FIG. The suction force is
It is much smaller than the turning force of the movable rail 1, and is configured to urge the tip rail 2 toward the running surface b of the rail to prevent it from floating. Furthermore, the magnet 7 can be provided above the outer guide surfaces 5c, 6c as required.

Furthermore, a portion of the vertical shaft 3 that connects the movable side tip of the movable rail 1, the tip rail 2, and the base is provided with an appropriate frictional force and a spring to prevent the tip rail 2 from rotating unnecessarily when the movable rail 1 turns. An appropriate biasing force is applied to add rotation resistance, and the tip rail 2 is restricted to be able to rotate only within the range of the branch guide angle α and the direct guide angle β with respect to the movable rail 1. A stopper (not shown) is provided.

The illustrated embodiment of the present invention has the structure described above, and its effects will be explained below. As shown in FIG. 8, the movable rail 1 is rotated to the right so that the tip rail 2 is aligned with the outer guide surface 5 on the direct rail 10b side.
c, the tip rail 2 becomes a branch guide angle α with respect to the movable rail 1, and the main rail 10
One guide side and running surface between the branch rail 10a and the movable rail 1 are formed by the movable rail 1 and the tip rail 2, and the movable rail 1 is in a branch running posture as shown in the figure. Then, at the beginning of the turning operation, the tip rail 2
Since the tip end 2a of the rail 2a is attracted by the magnet 7, the tip rail 2 is rotated relative to the movable rail 1 as shown in FIG. , the same direct guide angle becomes β, and the movable rail 1 and the tip rail 2
is rotated, and the tip end 2a of the tip rail 2 enters a slow movement state, and as shown in FIG. Since the end rail 2 is brought into contact with the outer guide side surface 6c to take a direct running posture, the collision of the tip rail 2 with the outer guide side surface 6c is avoided, and at the same time, the tip rail 2 comes into contact with the outer guide side surface 6c at a slower speed, so that noise is almost eliminated and the outer guide side surface 6c is not damaged. Therefore, even if rubber or the like is provided for cushioning on the outer guide side surface 6c, there is almost no damage to it, and impact and noise can be completely prevented.

Conversely, when the movable rail 1 is switched from the direct running attitude shown in FIG. 10 to the branching running attitude shown in FIG. When separating from the outer guide side surface 6c, the tip of the tip rail 2 moves slowly with respect to the movable rail 1 due to the attraction force of the magnet 7, and automatically changes to the branch running angle α, so that the tip rail 2 is guided to the outside. Abutting on the side surface 5c in a parallel state,
The above-mentioned effects can be obtained.

Furthermore, in the branch running position shown in FIG. 8 and the direct running position shown in FIG. The actuation is precise and the holding force significantly increases the guiding performance, significantly improving turning performance and reliability.

In addition, although the rail branch switching device for a suspended monorail has been described in the above embodiment, the present invention can also be applied to a similar switching device at a rail branch section having a guide side surface.
