Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a monorail point device on a monorail track, and more particularly to a monorail point device suitable for branching one track into multiple tracks.

Conventionally, the connection between the garage parking line of the monorail track and the main line has been provided by a switch device having a drive device as shown in Patent No. 490849, etc., but with such a switch device, the number of branching tracks is limited. When the number of branches is small and a large number of branches are to be made, several of the above-mentioned switching devices are installed and the switching is performed by a combination of these devices. Such a configuration has the disadvantage that a large number of switch devices are required, and the installation area thereof increases, making it necessary to increase the area of the entire garage. In addition, a plurality of drive devices must be interlocked, making the control device complicated and the operation complicated.

An object of the present invention is to provide a monorail point device that can branch from one fixed girder to two or more fixed girders with a simple configuration.

The present invention relates to a monorail point device that branches from one fixed girder to a plurality of fixed girders, in which the plurality of point girders are connected in the longitudinal direction, and one of the connected plurality of point girders is The end portion is rotatably mounted so as to correspond to the end portion of the one fixed girder, and the other end of the plurality of point girders is attached to each point position corresponding to the plurality of fixed girders. A rotary arm is provided at the bottom of each point girder and can be rotated synchronously by a drive device. The present invention is characterized in that a guide means is provided on the base to allow displacement of the tip of the arm in the direction of the axis of the point girder and to restrain displacement in a direction perpendicular to the axis of the point girder.

Next, an embodiment of a monorail point device according to the present invention will be described with reference to FIGS. 1 to 8. In the figure, M is the fixed girder on the side that is the source of the branch, 1
5 is a plurality of fixed girders on the branch side arranged in parallel. The switch device is provided between the fixed girder M and the fixed girders 1 to 5. The one-dot chain lines in FIG. 1 indicate the switch positions of the switch girders 16 corresponding to the fixed girders 1 to 5. Reference numerals 7 to 9 designate groove guides corresponding to guide means provided on the ground foundation surface 6 so as to be located at the center of the point positions of the respective point girders 16.
The groove guides 7 to 9 have grooves that open upward and extend in the longitudinal direction of the point girder 16. Incidentally, in the case of this embodiment, the groove guides 7, 8, and 9 are provided not only at the center of the switch position but also on both sides of each switch position at a distance of half the switch pitch. That is, at the point positions of fixed girders 1 and 5, groove guides 7, 8, 9 are also provided on the outside.
has been established. By this, the point girder 16
is held and fixed in the same way no matter what point position it is in. Next, each point girder 16a, 16
b and 16c are connected to each other so that they can be bent horizontally around a vertical axis. By the way, for convenience of explanation, the alphanumeric characters (a, b, c) attached to the symbols are used when each switch digit is distinguished and explained, and are omitted when the switch digits are collectively referred to.

The point girder 16 is supported at both ends by a truck 15, and the truck 15 is configured to be movable on rails 19. However, the point digit 16
Only the end of c on the fixed girder M side is rotatably mounted on the ground foundation surface 6 with the center of rotation aligned with the end face of the fixed girder M. Further, the rail 19 is installed in an arc shape centered on the center of rotation of the point girder 16c.

A driving device 14 is provided on the lower surface of each point girder 16.
are provided for each. The drive device 14 has an electric motor 17 serving as a power source. Further, the drive device 14 is provided with a shaft 18 that projects downward and is rotationally driven by an electric motor 17 via a speed reduction mechanism such as a gear. The shaft 18 is provided with crank arms 11, 12, and 13, which correspond to rotating arms and have rollers 10 attached to their ends. That is, the crank arm 11 is attached to the shaft 18 of the point girder 16a, the crank arm 12 is attached to the point girder 16b,
A crank arm 13 is provided on the point girder 16c.

The crank arms 11, 12, 13 rotate in synchronization with each other during operation. Furthermore, the lengths of the crank arms 11, 12, 13 are different from each other in correspondence with the moving distance of each point girder 16.

Roller 1 of each crank arm 11, 12, 13
0 is a size that can fit into each groove of the groove guides 7, 8, and 9. In addition, the crank arm 11,1
2, 13 and the groove guides 7, 8, 9, as shown in FIG. 4, the roller 10 fits into the groove, and the crank arm 11,
12 and 13 are at positions perpendicular to the longitudinal axis of the point girder 16, and the rollers 10 at both ends are located in one of the grooves of the groove guides 7, 8, and 9 installed on both sides of the point girder 16. It is arranged so that it fits into the end.

In such a configuration, the operation status of the switch will be explained with reference to FIGS. 1 and 5 to 8. In FIG. 1, the switch girder 16 is in a switch position corresponding to the fixed girder 2, and the operating situation from this state to the switch position corresponding to the fixed girder 3 will be explained. First, in the state shown in FIG. 1, the crank arms 11, 12, and 13 are rotated by the drive device 14 in the direction shown by the arrow in the figure. Due to the rotation of the crank arms 11, 12, 13, the fixed girder 1 side of the crank arms 11, 12, 13 (lower side in the figure)
The roller 10 fitted in the groove guides 7, 8, 9 of
are removed from the groove guides 7, 8, and 9. On the other hand, the rollers 10 fitted in the groove guides 7, 8, 9 on the fixed girder 3 side (upper side in the figure) of the crank arms 11, 12, 13 move inside the grooves of the groove guides 7, 8, 9 along their longitudinal direction. move in the direction. This state is the state shown in FIG.

By the way, the crank arms 11, 12, 1
3, the position of each roller 10 gradually becomes shorter in distance from the longitudinal axis of the point girder 16. It also moves in the axial direction of the point girder 16. Therefore, the roller 10 is connected to the crank arm 1
1, 12, and 13, the rollers 10 move within the grooves of the groove guides 7, 8, and 9, and the rollers 10
The change in the distance between the point and the point girder 16 pushes the groove guides 7, 8, 9 in the direction opposite to the point movement direction. As a reaction force to the operating force of the roller 10 on the groove guides 7, 8, and 9, an operating force is generated in the rolling point girder 16 in the rolling direction. That is, the groove guides 7, 8, and 9 are configured to allow displacement of the roller 10 in the direction of the point girder axis, and to restrict displacement in a direction perpendicular to the point girder axis. .

Next, as shown in FIG.
With the points 1, 12, and 13 aligned with the axis of the point girder, the point girder 16 overlaps the center of the point position, that is, above the groove guides 7, 8, and 9. When the crank arms 11, 12, 13 further rotate from this state, the rollers 10 move in the grooves of the groove guides 7, 8, 9 in the opposite direction. That is, the state shown in FIG. 7 is reached.

In the state shown in FIG. 7, the rotation of the crank arms 11, 12, 13 causes the roller 10 to move away from the axis of the rolling girder. Therefore, the reaction force of the roller 10 pushing the groove guides 7, 8, 9 moves the point girder 16 in the direction of the point position corresponding to the fixed girder 3.

And the crank arms 11, 12, 13
When the point girder 16 is positioned perpendicular to the point girder axis, the point girder 16 reaches the point position corresponding to the fixed girder 3. In this state, crank arms 11, 1
2 and 13 are stopped, the point girder 16 is fixed at the point position corresponding to the fixed girder 3. At this time, the rollers 10 provided at both ends of the crank arms 11, 12, 13 fit into the groove guides 7, 8, 9 installed on both sides of the point position corresponding to the fixed girder 3. .

The above explanation deals with the situation in which the point girder 16 is moved from the point position of the fixed girder 2 to the point position of the fixed girder 3. If so, the point girder 16 moves in the direction of the fixed girders 4 and 5. Further, if the crank arms 11, 12, 13 are turned counterclockwise, the point girder 16 moves in the direction of the fixed girders 2 and 1. According to such a configuration, each point girder 16 is provided with the drive device 14 and the crank arms 11, 12, 13, which are drive means, and the respective drive means are operated synchronously. double digit 1
6 allows smooth rolling motion. In addition, the difference in the moving distance of each point girder 16 is
This can be solved by changing the lengths of 1, 12, and 13 and synchronizing their turning angles.

Next, according to such a configuration, the point girder 16 can be easily moved to each point position of the fixed girders 1 to 5 by simply rotating the crank arms 11, 12, and 13, which are rotating arms. be able to. In addition, according to the above-mentioned configuration, it is possible to transfer from the fixed girder M to a large number of fixed girders, that is, two or more fixed girders using one switching device, and the structure is simplified and It is possible to achieve a reduction in the installation area. That is, by providing a driving device and a rotary arm on the point girder and providing a guide means on the foundation, the rotary arm sequentially engages with the guide means simply by rotating the rotary arm, and the point girder can be moved and easily transferred to two or more fixed girders.

In the above-mentioned embodiment, the shapes of the groove guides 7, 8, 9 of the guide means installed on the ground foundation surface and the rollers 10 provided at the tips of the crank arms 11, 12, 13 of the rotating arms are the same as in the above-mentioned embodiment. However, the structure is such that the two can be removably engaged and allow displacement of the tip of the rotary arm in the direction of the axis of the point girder while restraining displacement in a direction perpendicular to the axis of the point girder. Good to have.

Furthermore, if the groove guide is installed at an arbitrary position and the length of the crank arm is set in accordance with the installation position of the groove guide, it is also possible to make the shaft roll in the same way as in the above embodiment.

As explained above, according to the present invention, one fixed girder can be branched into two or more fixed girders with a simple configuration.
