Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a guide path bending device for a traverser branching device of a superconducting magnetically levitated railway.
[0002]
[Prior art]
Conventionally, the structure of a traverser branching device for a superconducting magnetic levitation railway has the following configuration.
[0003]
FIG. 6 is a cross-sectional view of such a conventional superconducting maglev railway traverser branching device.
[0004]
In this figure, 211 is a vehicle body, 212 is a guide wheel (hereinafter referred to as a guide wheel), 213 is a ground coil, 214 is a support wheel, 215 is a superconducting magnet, 216 is a support wheel travel path, and a concrete branch beam ( Guideway) 217 and a steel guideway 218.
[0005]
A magnetically levitated railway vehicle runs on a concrete track with a “U” -shaped cross section consisting of left and right walls and a floor instead of tracks. This trajectory is called the “guideway”.
[0006]
A support wheel traveling path 216 that runs on the support wheels 214 is installed on the floor, a ground coil 213 that conducts electricity from the substation is arranged on the wall, and a steel guide on which the left and right guide wheels 212 roll. Road 218 is attached.
[0007]
Therefore, when the magnetic levitation railway vehicle does not levitate and travel, the traveling support wheels 214 and the left and right guide wheels 212 travel in the guideway. The travel support wheel 214 and the left and right guide wheels 212 are both rubber tires.
[0008]
FIG. 7 is a schematic view of such a conventional superconducting magnetic levitation railway traverser branching device. FIG. 7 (a) is a schematic plan view showing a case where the guide path is in a straight state without being bent, and FIG. 7 (b). FIG. 5 is a schematic plan view showing a case where the guide path is curved and in a curved state.
[0009]
In these drawings, 201 indicates an inner track, 202 indicates an outer track, a white line portion indicates a branching girder 217, and a hatched portion indicates a steel guide path 218.
[0010]
When the guide path is in a straight line without being curved, the steel guide path 218 extends linearly in the same manner as the branch beam 217 as shown in FIG. On the other hand, when in the curved state, the branch beam 217 is in a bent state (described later), but as shown in FIG. 7B, a hydraulic jack (not shown) is arranged at the position indicated by the arrow. By pushing in this direction, the steel guide path 218 is curved so as to draw an arc so that the guide wheels 212 can smoothly travel.
[0011]
That is, since the branch girder (guideway) is made of a straight structure, a complete curve cannot be formed when both the function of both a straight line and a curve are required as in a branch device (point). For this reason, it is good if a plurality of branching girders (guideways) manufactured in units of length 12.6m are arranged in a straight line as in the case of a straight line configuration, but in the case of curve construction, a straight branching girder in units of 12.6m. (Guideway) will be lined up while changing the direction little by little.
[0012]
At this time, when two adjacent branch beams are viewed in plan, they are arranged in the shape of “<”, and this is called “corner break”.
[0013]
The gap between the branching girder and the next branching girder is typically 6 cm, but when forming a curve, the left and right gaps slightly expand on the outer rail side and slightly narrow on the inner rail side.
[0014]
If a magnetically levitated railway vehicle runs on a wheel with a branching girder in such a corner-folded state, the ride comfort becomes worse due to left-right swaying, but only on the surface through which the guide wheel 212 serving as a guide passes is broken. If it is possible to construct a curve without any problem, the vehicle can run smoothly.
[0015]
In the present branching device, the steel guide path 218 is separated from the concrete branch girder 217. When straight, both the branch girder 217 and the steel guide path 218 are straight [see FIG. 7 (a). However, the curved guideway is made of curved steel by pressing it with hydraulic jacks dedicated to the guideway at several places using the bending of steel.
[0016]
[Problems to be solved by the invention]
As described above, in the guide path of the conventional superconducting magnetic levitation railway traverser branching device, joints (joints) are provided for each girder in the same manner as the branching girder. In order to make the guide path curved when the curve is constructed, the guide path is curved in order to avoid contact between the vehicle and the ground coil 213, which is generated by extending the guide path from the straight line to the outside of the guide way. When doing so, make sure to operate in the direction of pressing. Therefore, the outer side (outer track) and the inner side (inner track) of the curve must be pressed at different positions, and the outer track must press the seam part of the guide path, so that there is no mistake in the joint. Two points are pressed. Further, since a plurality of hydraulic jacks dedicated to the guide path are provided, the configuration becomes complicated, and maintenance is difficult.
[0017]
The present invention eliminates the above-described problems, and the joints of the guide paths are arranged in a staggered manner, thereby eliminating the two points of pressing at the joints of the outer-rail guide paths, simplifying the mechanism, and guiding wheels. It is an object of the present invention to provide a guide path bending device for a traverser branching device that can perform smooth running according to the above.
[0018]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides
[1] the joint of trajectories side guide path and the outer trajectories side guide path of faces arranged to be staggered with each other, pressing the portion other than the seam portion of the guideway, traverser curving the guide path A guide path bending device of a branching device, wherein a guide path bending central mechanism of an inner gauge is disposed at a joint portion of the guide path of the inner gauge and connected to a link mechanism extending from both sides of the guide path bending central mechanism of the inner gauge. And a guide path bending mechanism that presses the position of approximately one third of the guide path of the inner gauge, and a guide path bending mechanism that is disposed at the center of the guide path of the outer gauge. To do.
[0019]
[ 2 ] In the guide path bending apparatus of the traverser branching apparatus according to [ 1 ], the guide path is obtained by using the amount of change in the gap between the branching girders caused by the corner folds of the branching girders generated when the branching device forms a curve. And a mechanism for bending the guide path.

Is pressed and curved. This is because the gap between the inner gauge side branching girders is reduced compared to the case of the straight state, and conversely, the gap between the outer gauge side branching girders is transmitted to expand. It is.
