3 will be described. The work vehicle 1 of the present invention is a guide rail type vehicle applied to a guide rail having a running surface of a vehicle and at least one guide surface provided along at least a laying direction of the running surface. The work vehicle 1 of this embodiment shown in FIG. 1 is used for rail construction, maintenance, and maintenance of a superconducting floating railway vehicle, and for rescue of a floating railway vehicle.

have.

Although not shown, a floating railway vehicle as a guide rail vehicle is drawn into a garage line by a work vehicle 1 as a guide rail vehicle. After the floating railway vehicle is stored in the garage, the work vehicle 1 pulling the floating railway vehicle enters the detention yard behind the garage. The detention area is flat and there is no guideway.

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

As shown in FIGS. 2 to 4, the vehicle body 11 of the working vehicle 1 is provided with traveling wheels 10 each of which is 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 king pin 13a so that it can swing in a plane. The tips of knuckle arms 14 (or steering arms) attached to the knuckles 13 are connected to each other by tie rods 15. Therefore, by operating each knuckle arm 14 and tie rod 15, a pair of running wheels 1
0 can be steered in the desired direction.

FIGS. 5 and 6 show the guide wheel device 20. FIG. In the figure, other guide devices are not shown for simplicity. The guide wheel device 20 has a structure symmetrical with respect to the center axis of the vehicle body 11. An arm receiver 21 is attached to a side surface of the vehicle main body 11 in parallel with a horizontal direction orthogonal to the central axis of the vehicle main body 11. The center of a 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. Mounting shafts 24 are fixed to both ends of the support arm 22, respectively.
Guide wheels 25 are rotatably attached to the upper ends of the four, respectively.

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 rail is a curved section,
The support arm 22 supporting the guide wheel 25 is a main guide surface 5 of the rail.
Rotates along. The rotation angle is approximately (1/2 of the dimension between the vehicle axles) / the radius of the curve. When the support arm 22 swings in this manner, the pair of knuckle arms 14 connected to the tie rods 15
The pair of running wheels 10 are steered in the same direction as the moving direction 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 cylinder at a predetermined position
7 are provided. Each air cylinder 27
A pin is connected to the vehicle body 11 at the rear end of the barrel.

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. When the stopper plate 28 swings outward, the stopper rubber 29
It is constituted so that it may be crimped to the inner surface of.

The tip of the rod of the air cylinder 27 is
The other end of the stopper plate 28 is connected by 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 air cylinder 27 extends the rod, each stopper plate 28 is pushed outward, and each stopper rubber 29 is pressed against the support arm 22, whereby the support arm 22 is parallel to the center 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 fixed without being steered and always oriented in a direction of traveling parallel to the central axis of the vehicle body 11.

When the traveling wheel 10 is constantly steered by the guide wheel device 20, it is caused by irregularities in the main guide surface 5, irregularities in the traveling surface 3, gaps between the guide wheel 25 and the main guide surface 5, and the like. Since the running wheels 10 are steered even by lateral movement during running, if the vehicle is driven at high speed in this state, the frequency of the steering operation increases, and the running stability of the vehicle may be impaired and snake behavior may occur. There is. However, in a state where the guide wheels 25 are fixed by driving the air cylinder 27 as in the present embodiment, the running wheels 10 are no longer steered, so that the stability of the vehicle when traveling at high speed in a straight section of the rail or the like is high. Is significantly improved.

Also, as described above, the guide wheel 25 and the traveling wheel 10
In the state where is fixed, the guide wheels 25 of the vehicle are bent by receiving a force from the main guide surface 5 when passing through a curved section of the rail or the like, and the traveling wheels 10 of the vehicle also undergo lateral deflection or slip. That is, although the vehicle travels while being guided by the forced guidance system, the inconvenience such as wear of the traveling wheel 10 due to slippage or the like hardly causes a problem with a large radius curve.
High-speed driving stability is ensured.

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 as to be a semi-forced guide system in which the piston of No. 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 employed. For example, if the strength of the side wall 4 constituting the main guide surface 5 is 1 ton, 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. Is driven by the forced guide system, and only when there is a step such as a seam 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 a fixing means of the guide wheel device 20, in addition to the air cylinder 27, a hydraulic cylinder provided in a hydraulic circuit having an accumulator can be used.

As described above, since the work vehicle 1 of this 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 as the fixing means is reduced. If the fixing force is adjusted by adjusting, the condition of the traveling rail and the traveling speed are selected from the forced guidance system, the semi-forced guidance system, and the guide steering system in which the guide wheel device 20 and the traveling wheel 10 are linked. Can be selected in accordance with the method. Thus, the work vehicle 1 of the present embodiment can achieve both stable high-speed traveling and low-speed traveling in a curved section with a small radius.

FIGS. 7 to 9 show the guide wheel device 30. FIG. In the figure, other guide devices are not shown for simplicity except for common parts. The guide wheel device 30 has a symmetrical structure with respect to the center axis of the vehicle body 11. 31
Is a steering arm having the same function in structure as the knuckle arm 14 shown in FIGS. Each of the steering arms 31 is connected to the knuckle 13, and among the pair of steering arms 31, 31 located symmetrically with respect to the center axis of the vehicle body 11, each of the pair of steering arms 31, 31 located forward with respect to the kingpin 13 a. The tip is connected by a pin by a tie rod 32.

At the front end of the steering arm 31 forward with respect to the king pin 13a and at the rear end of the steering arm 31 rear with respect to the king pin 13a, brackets 35 for mounting the rotating shafts 34 of the guide wheels 33 are provided.
Is provided. The bracket 35 is attached to the vehicle body 1
A pin is attached to the steering arm 31 so as to be swingable in a vertical plane parallel to the center axis of the steering arm 31.
A guide wheel 33 is rotatably provided at a lower end of a rotating shaft 34 fixed to the bracket 35. The front end of the front steering arm 31 and the rear end of the rear steering arm 31 are respectively connected by pins to the rear end of the barrel of the air cylinder 36 that is the driving means. The tip of the rod of each air cylinder 36 is connected to the corresponding bracket 35 by a pin.

When the rod of the air cylinder 36 extends,
The rotating shaft 34 of the guide wheel 33 is set at a guide position parallel to the vertical line, and the guide wheel 33 is
Touch the side of the When the rod of the air cylinder 36 is retracted, the rotating shaft 34 of the guide wheel 33 is pulled upward, and the guide wheel 33 is set at the upper retreat position away from the guide blade 9 on the side line 8.

When the guide wheel 33 is guided by the guide blade 9, the pair of steering arms 31 to which the guide wheel 33 is attached and which are connected to each other interlock with this, and the traveling wheels 10 provided on the steering arm 31 are operated. Turned

FIGS. 10 to 12 show the auxiliary wheel device 40. FIG.
In the figure, other guide devices are not shown for simplicity except for common parts. The auxiliary wheel device 40 has a symmetrical structure with respect to the center axis of the vehicle body 11.

An auxiliary wheel 42 is provided at each end of the steering arm 31 via an auxiliary wheel bearing 41. The auxiliary wheel 42 has a rotation axis parallel to the vertical line, and is guided in contact with the auxiliary guide surface 7 of the groove 6 provided at the center of the running surface 3.

As shown in FIG. 10, a pair of steering arms 31, 31 disposed behind the king pin 13a.
The auxiliary wheel bearing 41 provided at each rear end of the tie rod 4
3 are connected. The tie rod 43 and the auxiliary wheel 42 are attached only during the construction work of the main line 2 or the like, and are removed in other cases. During normal use, the steering arm 31 is connected with the tie rod 32 shown in FIG. However, the tie rods 15, 32,
The operation of linking the steering arm 31 (or the knuckle arm 14) is not changed if any one of the steering arms 31 is attached. However, the auxiliary wheel bearing 41 is attached to a position where the steering arm 31 is extended from the structure shown in FIG. In such a case, if the tie rod 43 is attached here, the burden load on the tie rod is reduced.

When the auxiliary wheel 42 is guided by the auxiliary guide surface 7, the pair of steering arms 31 to which the auxiliary wheel 42 is attached and which are connected to each other interlock with this, and the traveling wheel 10 provided on the steering arm 31 is moved. 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. This steering device is a device for directly steering the traveling wheel 10, and is useful when traveling on a flat field without a guide surface of each of the guide devices.

The guide wheel device 20, the guide wheel device 3
0, or when the traveling wheel 10 is steered by the auxiliary wheel device 40, that is, when the work vehicle 1 travels on a rail having some guide surface, the handle of the steering wheel steering device is on the traveling wheel 10 side. It is driven by and rotates. However, switching means may be provided in the steering wheel steering device so that the traveling wheels 10 can be steered by the steering wheel steering device only when traveling on a flat surface, and the steering wheel may not move during rail running.

Next, the operation of the above configuration will be described. When traveling on the main line 2, the guide wheel device 20 is used. The guide wheel device 30 is retracted to the upper evacuation position. The auxiliary wheel device 40 is removed. When the work vehicle 1 travels on the traveling surface 3 of the main line 2, the guide wheel 25 contacts the main guide surface 5 of the side wall 4 of the main line 2 and rotates.

When the vehicle travels at a low speed in a small radius curve section of the main line 2, the rod of the air cylinder 27 of the guide wheel device 20 is retracted. Support arm 22 having guide wheels 25
Is not fixed and can swing about the bearing 23. Therefore, when the rail is curved, the guide arm 25 rolls along the curved surface of the main guide surface 5, and the support arm 22 swings. The swing of the support arm 22 is transmitted to the knuckle arm 14 (steering arm 31) and the knuckle 13 via the rod 26, and the traveling wheel 10 is steered so as to face the direction in which the rail is bent.

When the vehicle travels at high speed in the straight section of the main line 2, the rod of the air cylinder 27 of the guide wheel device 20 is made to protrude. The support arm 22 having the guide wheel 25 is fixed in a posture parallel to the central axis of the vehicle body 11. Therefore, the guide wheel device 20 and the traveling wheel 10 do not swing, and the traveling wheel 1
The direction of 0 is fixed toward the front of the rail. For this reason,
Even when the work vehicle 1 travels at high speed, the entire movement of the guide wheels 25 is not transmitted to the travel wheels 10, and no snake action occurs in the travel of the work vehicle 1.

As described above, if the force by which the air cylinder 27 fixes the support arm 22 is appropriately set, particularly when the air cylinder 27 passes through a joint or the like of the main guide surface 5 where a strong force acts on the guide wheel 25. Only the support arm 22 receives the force and swings, so that the traveling wheel 10 can be steered.

When traveling on the side line 8, the guide wheel device 3
0 is used. That is, as shown in FIG.
Is extended to set the guide wheel device 30 to the lower guide position. Since there is no main guide surface 5 on the side line 8, the guide wheel device 20 does not operate. The auxiliary wheel device 40 is removed. When the work vehicle 1 travels on the traveling surface 3 of the side line 8, the guide wheel 33 contacts the guide blade 9 of the side line 8 and rotates.

When traveling on the main line 2 under construction, the auxiliary wheel device 40 is attached to the steering arm 31 of the vehicle body 11.
Attach. When constructing the main line,
Is constructed, and then the side wall 4 is constructed. Side wall 4
The guide wheel device 20 does not operate because the main guideway 5 does not exist on the main line under construction without the guideway. The guide wheel 33 retracts the rod of the air cylinder 36 and retracts it to the upper retreat position. When the work vehicle 1 runs on the running surface 3 of the main line 2 under construction, the auxiliary wheel 42 comes into contact with the auxiliary guide surface 7 of the groove of the running surface 3 and rotates.

After pulling the linear car into the garage, the working vehicle 1 exits the garage and enters a flat field. When traveling on a flat ground, there is no guide surface, so the driver steers the work vehicle 1 with the steering wheel steering device.

As described above, the working vehicle 1 of the present embodiment
According to the present invention, the guide wheel device 2 provided with a means for fixing the guide wheel 25
0 allows both high-speed running and low-speed running, and the guide wheel device 30 allows the vehicle to run on the side line 8, and the auxiliary wheel device 40 allows the vehicle to run on a main line under construction without the main guide surface 5. .
