Then, after the levitation railway vehicle is stored in the garage, the work vehicle 1 that has pulled the levitation railway vehicle into the depot located behind the garage. The storage area is flat and there is no guideway.

A work vehicle 1 as a guide rail type vehicle is shown in FIG.
~ As shown in FIG. 4, a vehicle body 11 having traveling wheels 10
And three types of guide devices provided in the vehicle body 11. These guide devices are used properly according to the guide rails having various forms as described above. The guide wheel device 20, which is the first guide device, is used when traveling on the main line 2. The guide wheel device 30, which is the second guide device, is used when traveling on the lateral line 8. The auxiliary wheel device 40, which is a third guide device, is used when traveling on the main line 2 under construction.

As shown in FIGS. 2 to 4, the vehicle body 11 of the work vehicle 1 is provided with traveling wheels 10 that make a pair of left and right. Each running wheel 10 is rotatably attached to both ends of an axle 12 via knuckles 13. Each knuckle 13 is attached to the axle 12 via a kingpin 13a so that it can swing in a plane. The tips of knuckle arms 14 (or steering arms) attached to each knuckle 13 are connected to each other by a tie rod 15. Therefore, by operating each knuckle arm 14 and tie rod 15, the pair of running wheels 1
0 can be steered in the desired direction.

A guide wheel device 20 is shown in FIGS. In the figure, the other guide devices are not shown for the sake of clarity. The guide wheel device 20 has a symmetrical structure with respect to the central axis of the vehicle body 11. An arm receiver 21 is attached to a side surface of the vehicle body 11 in parallel with a horizontal direction orthogonal to a central axis of the vehicle body 11. The central portion of the support arm 22 is attached to the tip of the arm receiver 21 via a bearing 23. The support arm 22 swings about a bearing 23 in a horizontal plane. Attachment shafts 24 are fixed to both ends of the support arm 22, respectively.
A guide wheel 25 is rotatably attached to the upper end of each of the four.

The lower end of the mounting shaft 24 and the knuckle arm 14 are interlockingly connected by a rod 26 as interlocking means. Therefore, if the track is a curved section,
The support arm 22 supporting the guide wheel 25 is the main guide surface 5 of the rail.
Rotate along. The rotation angle is approximately (1/2 of the dimension between vehicle axles) / curve radius. When the support arm 22 swings in this manner, the pair of knuckle arms 14 connected to the tie rods 15 are connected to the kingpins 13 respectively.
Rotating about a, the pair of traveling wheels 10 are steered in the same direction as the direction of movement of the guide wheel device 20.

On the side surface of the vehicle body 11, guide wheels 25 to support arms 22 are provided at respective positions on both sides of the arm receiver 21.
Cylinder 2 as a fixing means for fixing the air cylinder in place
7 are provided respectively. Each air cylinder 27
The rear end of the barrel is pin-connected to the vehicle body 11.

Further, inside the support arm 22, stopper plates 28 are provided at positions on both sides of the arm receiver 21, respectively. One end of each stopper plate 28 is pin-connected to a portion of the support arm 22 near the arm receiver 21. A stopper rubber 29 is provided on the outer surface of the other end of the stopper plate 28, and when the stopper plate 28 swings outward, the stopper rubber 29 is used by the support arm 22.
It is configured to be crimped to the inner surface of the.

The tip of the rod of the air cylinder 27 is
The other end of the stopper plate 28 is connected with a pin. Therefore, when the air cylinder 27 is retracting the rod, the support arm 22 can freely swing along the curve of the main guide surface 5 of the rail. When the rod is extended by the air cylinder 27, the stopper plates 28 are pushed outward so that the stopper rubbers 29 are pressed against the support arms 22, so that the support arms 22 are parallel to the central axis of the vehicle body 11. Fixed in position.

When the support arm 22 is fixed by the air cylinder 27, the positional relationship between the guide wheel 25 and the vehicle body 11 is fixed. At this time, the traveling wheels 10 are not steered, and are fixed in such a state that they are always oriented in a traveling direction parallel to the central axis of the vehicle body 11.

When the traveling wheels 10 are constantly being steered by the guide wheel device 20, this is caused by irregularities in the main guide surface 5, irregularities in the traveling surface 3, gaps between the guide wheels 25 and the main guide surface 5, and the like. Since the traveling wheel 10 is steered even by left and right movements during traveling, if the vehicle is traveling at high speed in this state, the frequency of steering operation will increase, and the running stability of the vehicle will be impaired, and snake action may occur. There is. However, as in the present embodiment, when the guide wheels 25 are fixed by driving the air cylinder 27, the traveling wheels 10 are also not steered, so the stability of the vehicle when traveling at high speed in a straight section of the railroad or the like. Is much improved.

Further, in this way, the guide wheel 25 and the traveling wheel 10 are
When the vehicle is fixed, the guide wheel 25 of the vehicle bends by receiving a force from the main guide surface 5 when passing through a curved section of the rail, and the running wheels 10 of the vehicle also undergo lateral deflection or slip. That is, the vehicle travels while being guided by the forced guidance system, but the inconvenience such as wear due to slipping of the traveling wheels 10 causes almost no problem with a large radius curve,
High-speed driving stability is secured.

When a force that damages the main guide surface 5 is applied when passing through the curved section, the air cylinder 2
The pressure of the air cylinder may be set so that a semi-forced guide system is adopted in which the piston 7 is pushed and the displacement of the guide wheel 25 is allowed.

The magnitude of the reference force at that time is as follows.
For example, a force that the guide wheel 25 always receives from the main guide surface 5 may be adopted. For example, if the strength of the side wall 4 constituting the main guide surface 5 is 1 ton, if the inner diameter of the air cylinder 27 is 125 mm, the air pressure is 5 kgf / cm ² , and the force of the air cylinder 27 is 600 kgf, then the main line 2 is almost the same. Is driven by the forced guide system, and only when there is a step like the joint of the main guide surface 5, the support arm 22 receives the force from the guide wheel 25 to rotate, and the running wheel 10 is steered.

As the fixing means of the guide wheel device 20, in addition to the air cylinder 27, a hydraulic cylinder provided in a hydraulic circuit equipped with an accumulator may be used.

As described above, since the work vehicle 1 of the present embodiment, which is a guide rail type vehicle, has the guide wheel device 20 provided with the fixing means, the cylinder pressure of the air cylinder 27, which is the fixing means, is reduced. If the fixed force is adjusted by adjusting, the condition of the running track, the running speed, etc. can be selected from among the forced guide system, the semi-forced guide system, and the guide steering system in which the guide wheel device 20 and the running wheels 10 are interlocked. A method suitable for As a result, the work vehicle 1 of the present embodiment is capable of both stable high-speed traveling and low-speed traveling in a curved section with a small radius.

If any one of 43 is attached, the operation of interlocking the steering arm 31 (or the knuckle arm 14) is the same, but the auxiliary wheel bearing 41 is attached to the extended position of the steering arm 31 due to the structure. In such a case, if the tie rod 43 is attached here, the load on the tie rod is reduced.

When the auxiliary wheels 42 are guided to the auxiliary guide surface 7, the pair of steering arms 31 to which the auxiliary wheels 42 are attached and connected to each other interlock with each other, and the traveling wheels 10 provided on the steering arm 31 are connected. Steered.

Next, the working vehicle 1 of the present embodiment is a guide rail type vehicle, but a steering wheel steering device is provided in the cockpit of the vehicle. This steering device is a device for steering the traveling wheels 10 directly, and is useful when traveling on a flat field without the guide surface of each of the guide devices.
