Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a one-side pressing side guide type in which one of the left and right guide wheels installed on the guide shaft is pressed against a guide rail provided on the side of the track to guide the vehicle. The present invention relates to a vehicle guidance method and device.

Conventionally, in vehicle operation systems called new transportation systems, special tracks with different widths are created for large vehicles and small vehicles, depending on the size of the vehicle (overall length, width, distance between axles, etc.). Large vehicles and small vehicles run separately on this track.

However, when considering actually efficient transportation and operation modes, it is most rational to have vehicles of various sizes, both large and small, coexist on the same track, just as on general roads. In this case, the width of the track will be determined according to the travel trajectory of the largest vehicle.

However, when this method is applied to a one-sided push-and-side guide vehicle, the following problems arise.

For example, in a track branch as shown in FIG. 5, left and right guide shafts b+ are installed on guide shaft a.

In order to branch the small vehicle M running on the left side, where the left side guide wheels are in contact with the left side guide rail CIVC, to the right in the figure, it is necessary to switch to the right side guide before the branch point. Conventionally, this switching involves reversing to the right the leftward pressing force applied to the left guide wheel b1 through the guide shaft a by a spring, steering the running wheels Dw and D to the right, and switching the right guide wheel to the right.

This is done by pressing the right guide rail Ct. However, at the time of this switching, the running wheel DI.

Since D is steered to the right at the maximum angle, the running condition becomes extremely unstable, and there is a risk that the vehicle M may slip or fall.

In addition, in the case of electric cars, the current collector protruding from the car body is made to slide into contact with the power feeder line provided along the guide rails to receive power. Since there is a power outage section in which the device is far from either the left or right feeder lines, there is a risk that vehicles may become stuck in these sections, causing problems with running.

Such problems are not limited to branching sections, but occur in all track positioning devices where it is necessary to switch the guiding direction of a vehicle, such as when switching the guiding direction to make a large vehicle travel outward at a curved track section.

For PJLC, it was considered difficult to realize a mixed running system for large and small vehicles on the same track.

Therefore, the present invention solves the above-mentioned problems at branch points, etc., and allows the vehicle guidance direction to be switched smoothly and without any hindrance, thereby making it possible for large and small vehicles to coexist on the same track. It is an object of the present invention to provide a guiding method and device for a one-side push side guiding vehicle.

The method of the present invention is characterized in that the guide shaft is configured to be expandable and retractable into a normal length in which only one guide ring is in contact with the guide rail, and an extended length in which both guide wheels are in contact with the guide rail. When changing the guidance direction by the guide rail,
The guide shaft is extended from its normal length so that the left and right guide wheels are in contact with the guide rails on both sides, and in this state, the direction of pressing the guide wheels is reversed, and then the guide shaft is reduced to its normal length and the guide direction is It consists in switching between the two.

In addition, the device of the present invention includes a guide shaft equipped with guide wheels on both left and right sides, a biasing body that biases the guide shaft with a force directed toward either the left or right, and a biasing body that applies a force to the guide shaft. In a guide device for a one-sided pushing side guide type vehicle, which is equipped with a switching mechanism for switching the biasing direction of a force to the left or right side, and is configured to push a guide wheel on either the left or right side against a guide rail to guide the vehicle. , the guide shaft is formed by a guide shaft main body and a guide wheel mounting shaft connected to both sides of the main body so as to be movable from side to side. It is characterized in that it is configured to be able to expand and contract to an extended length that can come into contact with the rail, and that a telescopic cylinder is provided between the guide shaft main body and the guide wheel mounting shafts on both sides.

The invention will now be explained by means of illustrated embodiments.

FIG. 1 illustrates a case where the guiding direction of a small vehicle M is switched from left to right at a track branch.

The widths of the main track R and the branch track R' are set to match the travel trajectory of a large vehicle (not shown), and the small vehicle Y runs on the main track R with left-hand guidance.

That is, 1 is a guide shaft, 2 and 3 are left and right guide shafts installed on both sides of this guide shaft 1, 4 and 5 are guide rails on both sides of the main line and branch tracks R and R', and the vehicle M is on the left side. Guide wheel 2
runs in the direction of the arrow on the main track R with the left guide where it contacts the right guide rail 4, and at a predetermined position before entering the branch track R', the right bundle, the inner ring 3 contacts the right guide rail 5. Switched to guidance.

Details of the guide device will be explained with reference to FIGS. 2 to 4.

6 is the axle, 7 and 8 are the left and right running wheels (front wheels to be steered),
910 is a knuckle arm, and 11 is a tie rod. 1
2 is the steering arm, and the rear part is attached to the axle 6 with a vertical pin 1
3, the rear end is operatively connected to the left knuckle arm 9 via a link 14, and the front end is interlocked to the center of the guide shaft 1 via a link 15. A switching plate 16 is attached to the steering arm 12 via the pin 13.
A compression spring 17 is provided between the free end of the switching plate 16 and the axle 6. The spring force of this spring 17 is applied to the steering arm 12 via the switching plate 16, and the switching plate 16
When the is in the position shown by the solid line in Figure 2, a rotational moment in the direction of arrow A is applied to the steering arm 12 due to the spring force, so a pressing force is applied to the guide shaft 1 in the left direction as shown by arrow A'. It will be done. Furthermore, when the switching plate 16 is changed to the position shown by the imaginary line in FIG.
In order to apply a turning moment in the direction of the arrow to the guide shaft 1, a rightward pressing force as indicated by the arrow d is applied to the guide shaft 1. Reference numeral 18 denotes a switching cylinder for changing the attitude of the switching plate 16 as described above, and a support arm supporting the guide shaft 1 at 19.degree. and 20.degree. In addition, a left switching confirmation switch 21 is turned on when the switching plate 16 is set to the position shown by the solid line in FIG.
This is a right-hand switch that turns on when it is seen.

The guide shaft 1 is configured to be expandable and retractable by a guide shaft main body 23 supported by a support arm 19.20 and a guide wheel attachment shaft 24.24 to which guide wheels 2 and 3 are attached. That is, double-acting telescopic cylinders 25.25 are provided inside the left and right sides of the guide shaft main body 23, and the guide ring mounting shaft 24. 24 are fitted and connected.

The left and right telescopic cylinders 25.25 operate synchronously, and the telescopic operation of the cylinders 25.25 causes the guide wheel mounting shaft 24.2 to
4 moves in the axial direction, thereby allowing the guide shaft 1 to expand and contract as a whole.

Fig. 3 shows the guide shaft in its contracted state, and Fig. 4 shows its extended state. Normally, the guide shaft 1 is used at its normal length so that only the left guide wheel 2 can come into contact with the left guide rail 4 when leading. The length is changed to the extended length when the vehicle guidance direction is changed at the branching point. In addition, at the connecting portion between the guide shaft main body 23 and the guide wheel mounting shafts 24, 24 on both sides, a compression coil spring 27 for buffering is provided between the main body 23 and the connecting block 26 when the telescopic cylinder 25 is contracted from the extended position. It is provided. Further, the guide wheel mounting shaft 24 is connected to the connecting block 26 so as to be able to move a certain distance in the axial direction, and a pressure confirmation switch 28 is attached to the opposing surfaces of the two 24 and 26.
A convex portion 29 for pushing this is provided. 30 is a buffer spring for this switch operation, and 31 is a bellows-shaped cover.

On the other hand, a switching protrusion 32 is provided at the other end of the piston rod 25a of the telescopic cylinder 25.
2 operates a reduction confirmation switch 33 and an extension confirmation switch 34, which are provided on the inner surface of the guide shaft body 23 at a predetermined interval in the axial direction, in response to the expansion and contraction operations of the telescoping cylinder 25.

Therefore, at the track branch shown in FIG. 1, when switching the guidance direction of the vehicle M from the left-hand guidance to the right-hand guidance before entering the branching track R', for example, a guidance direction switching command signal is sent from the ground side. Based on this, first, the telescopic cylinder 25.25 is operated to extend and the guide shaft l is extended (
Figure 1 M1 state). According to this extension of the guide shaft 1, the running wheels 7 and 8 are steered to the right, and the vehicle M moves to the right. When the guide shaft 1 reaches a predetermined extension length, both the guide wheels 2 and 3 on both sides move toward the guide rail. 4 and 5 (state of M2 in Figure 1)
. This state is confirmed by the pressure contact confirmation switch 28.2 in the guide shaft 1.
8 and the extension confirmation switch 34, the switching cylinder 18 is operated to move the switching plate 16 to the second position.
The posture is changed to the posture shown by the imaginary line in the figure, and the direction of the pressing force acting on the guide shaft l by the compression spring 17 is changed to the right side.

After confirming this switching by operating the right switching confirmation switch 22, the telescopic cylinders 25.25 are contracted. As a result, while the right guide wheel 3 is in contact with the right guide rail 5, the vehicle M moves to the right while the guide shaft 1 is reduced to its normal length, and finally only the right guide wheel 3 is in contact with the guide rail 5. It is switched to the right-hand guide where the guides roll in contact with each other (state M3 in FIG. 1). In this state, the vehicle M shifts from the main track R to the branch track R'.

For example, when the vehicle M travels on the main track R with right-hand guidance, if you want the vehicle M to go straight ahead without moving to the branch track R1, the vehicle M may move straight on the main track R.
This can be done in the same way when moving a vehicle traveling on the right-hand side to the left-hand branch track. This method and device also apply when switching the guiding direction of a large vehicle in a curved track section with a small radius of curvature so that it runs outward.In accordance with the present invention, the guiding direction of the vehicle can be switched at a track branching section, etc. In this case, the guide direction can be smoothly switched by the following process: extension of the guide shaft - simultaneous contact of the guide wheels 2, 3 on both sides with the guide rails 4, 5 - reversal of the direction in which the guide wheels are pressed - contraction of the guide shaft. In other words, when a one-side push side guide type vehicle is run on a track with a width larger than the vehicle width, when switching the guidance direction of the vehicle, the guide wheels and guide rails come into a non-contact state and the vehicle control is lost. There is no risk of being destroyed.

Further, in the case of an electric vehicle, even when the guiding direction is switched, at least the current collector on either the left or right side maintains contact with the power supply line, so there is no possibility of a power outage section occurring. Therefore, it is practically possible to have vehicles of various sizes coexist on the same track. For this reason, for example, a large number of branch tracks for large vehicles and small vehicles are extended from the closed-loop main line track, and large and small vehicles coexist on the main line track.
It will become possible to adopt a completely new and efficient vehicle operation system, such as distributing each vehicle to branch tracks depending on its destination, or conversely, merging from branch tracks to the main track.

By the way, the above-mentioned guide direction switching action is basically performed by the pressure contact confirmation switch 28, the reduction and extension confirmation switches 33 and 34, and the left and right switching confirmation switches 21 and 22.
However, in consideration of safety, it is desirable to configure a control system that includes signal elements other than the above-mentioned switches. An example of this is given below.

(a) The duration of the extended state of the guide shaft 1 is monitored by a timer, and if there is an excessive delay, a signal indicating that the vehicle cannot run is outputted and the vehicle is stopped.

(b) Even in areas other than junctions, the above timer constantly matches the guidance direction command and AM to monitor for discrepancies, and even if the discrepancy continues excessively, a signal indicating that the vehicle cannot run is output and the vehicle to stop.

(-f) Add a mileage kakunta to the above timer,
The distance traveled by the vehicle from the start of extension is counted, and if the vehicle exceeds a predetermined distance required for switching the guidance direction, a signal indicating that the vehicle cannot travel is outputted to stop the vehicle.

By adding the condition of G4)@(c) as a control element, a more accurate and safe guide direction switching action can be performed.

In addition, the specific connection structure between the guide shaft main body that constitutes the expandable guide shaft and the guide wheel mounting shafts on both sides, the support structure of the guide shaft to the vehicle body, and the pressing force applied to the guide shaft from side to side. The structure of the switching mechanism of the switching stopper may be changed to something other than the above-mentioned embodiment as appropriate. Moreover, as a biasing body that applies a pressing force to the guide shaft, other components such as an air cylinder may be used instead of the compression spring 17.

As described above, according to the present invention, it is possible to smoothly switch the vehicle guidance direction at a track branch, etc. without causing troubles such as destabilizing the vehicle running condition. This makes it actually possible to adopt an efficient vehicle operation system that allows large and small vehicles to travel together.
