Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a track branching device including a plurality of movable track girders for reducing the angle of incidence in a branching device such as an new transportation system.

This type of branching device has more relative moving parts compared to the conventional branching device with one movable track girder, so the structure is overloaded and the weight increases, which only increases equipment costs and maintenance costs. However, there were also problems from a safety standpoint, and improvements to these shortcomings were desired.

The present invention was made against the background of this situation, and the hinge part of each movable track girder is divided into a plurality of parts. At the movable side end of the girder, the movable track girder one movable track girder in the following order had a center bin support at the movable side end, and the movable track girder's movable side end was placed on the ground side with a sliding plate support tw was a roller bearing. Alternatively, in the present invention, the insertion hole of at least one center bin is formed as a long hole in the direction of the track axis, so that the moving side end of the movable track girder can be guided at right angles to the track axis direction. It is characterized by a guide that corresponds to the change in length in the track direction when the movable track girder turns, and has a simple structure with a fixed track girder, a movable track girder, and a pivotal support KIIL with the ground side. The object of this invention is to provide an inexpensive branching device that is not only light in weight but also excellent in safety.

Below is a single opening 2 of a 3-wire track with a running guide rail in the center
An embodiment of a horizontal rotation type branching device for a joint binge joint will be described based on the drawings.

Figures 1 and 2 are plan views of the tip in the normal and reverse positions, respectively, and Figures 3 and 4 are the plan views of the center bottle insertion hole in the full length hole in the normal and reverse positions. FIG. 5 is a side view of FIG. 1, and FIGS. 6, 7, and 8 are cross-sectional views of VI-VI, ■-■, and tow-■ of FIG. 1, respectively. .

The movable part disposed between the entrance side fixed orbit girder l and the branch side fixed orbit girder 2 is divided into two, and a first movable orbit girder 3 and a second movable orbit girder 4t are sequentially provided. The end portion 6 of the fixed orbit girder 1 on the entrance side is fixed to the basic structure 6 provided on the ground side.
A center bin 7 is erected at the center, and an insertion hole 9 formed at the end 8 of the first movable track girder 3 on the rotation center side is loosely fitted into the bin 7. It is supported so that it can rotate horizontally. This first movable orbit girder 30 rotation center end portion 8
The vertical load is supported by a sliding plate 1G provided at the end 6 of the input fixed track girder 1 and a sliding plate 11 provided at the end 8 of the first movable track girder 30 on the rotation center side, as shown in FIG. As shown in FIG. 7, the vertical load on the movable end 12 of the first movable track girder 3 is applied to the sliding plate 13 provided at the end 12, which is fixed onto the base plate 14 provided on the ground side. It is slidably supported by 15.

Center pin 1 erected on the moving end portion 12 of the first movable track girder 3
The gIC second movable track girder 4 is loosely fitted into the insertion hole 18 formed at the end 17 on the rotation center side, and is supported so as to rotate horizontally about the second movable track girder 4t - center bin 16t. Second
As shown in FIG. 7, the vertical load on the end 17 of the movable track girder 40 on the rotation center side is caused by the sliding plate 19 provided on the end 17 and the sliding plate provided on the end 12 of the first movable track girder 3 on the moving side. The plate 20t is supported at the moving end. A flanged roller 22 is pivotally supported at the lower part of the moving side end 2112) of the second movable track girder 4,
The roller 22t is installed on the ground side and laid on the friend foundation girder 23, and is engaged with the friend guide rail 24 so that the movable side end 21 of the second movable track girder 4 is guided at right angles to the track axis direction. It is rotatable in the horizontal direction, and as shown in FIG. 8, the vertical load at the movable end is supported by rollers through the body rollers 22 and guide rails 24.

Further, the insertion hole 18 formed in the second movable track girder 4 is formed as a long hole in the direction of the track axis. For convenience of manufacturing the guide rail 24t and for mutual compatibility between the branching devices, this is formed into a general arc centered on the center bin 7 of the fixed track girder l on the input side, as shown in FIG. Because the track axis length of the track girder 4 is bent between the first and second movable track girders 3 and 4, I when in the upright position in Figure 1 is shorter than 6 in the reverse position in Figure 2. I have to write it. For this purpose, the insertion hole 18 of the second movable track girder 4 is formed into a long hole in the track axis direction, so that the center bin 16 and allowing the insertion hole 18 to be displaced on the orbital axis;
The distance between the movable end 21 of the second movable track girder 4 and the end 25 of the branch fixed track girder 2 is configured to be constant. This elongated hole can effectively cope with out-of-synchronization of the movement of each movable track girder at the intermediate point of the switch.

In addition, in the above example, the movable track girder? The present invention is not limited to this, but the insertion hole may be a long hole in the direction of the sound axis, or a track girder other than the second movable track girder may be used, and the supporting means may be a sliding plate or a roller. Depending on the support requirements, horizontal guidance of the movable end of the movable track girder perpendicular to the track axis direction may also be achieved by uneven engagement between sliding plates instead of the combination of rollers and guide rails. .

Since the present invention is configured as described above, each movable track girder of the branching device, which is divided into the number of movable track girder movements and the angle of incidence is relaxed, is easily and firmly supported, and furthermore, it is safe. This has great effects, such as being able to cope with synchronization deviations in the movement of each movable track girder.
