And a drive gear 65 fixed to the drive shaft 53, and a rolling gear 69 pivotally supported by a support plate 67 fixed to the driven shaft 49 and meshing with the internal gear 63 and the drive gear 65. The power is decelerated and transmitted from the driven shaft 49 to the driven shaft 49. The auxiliary wheel 55 is
It engages with guide rails 71, 71 installed on the ground near both sides of the entrance end of the monorail 21 to roll on the upper surface. On the outer surface of the side plates 47 on both sides, on the front part and the rear part,
A horizontal roller 75 is rotatably supported by a bracket 73 so as to contact the inner surfaces of auxiliary guide rails 77, 77 installed on the ground near both sides of the guide rails 71, 71 so that the vehicle 1 can enter the posture. It is for positioning. In the speed reducer 51, the speed reduction ratio is set so that the peripheral speeds of the auxiliary wheel 55 and the drive sprocket 3 match.

Note that FIG. 8 shows a power system for driving the drive roller 37, and is configured as follows. That is, the main pump 83 and the auxiliary pump 85 of variable displacement are rotated via the belt 81 by the driving of the engine 79. When the engine 79 is running at a low speed, the oil in the oil tank 87 is driven by the auxiliary pump 85 so that the oil in the oil tank 87, the check valve 91, the filter 93, the check valve 95, the main pump
It is provided so as to return to the oil tank 87 via 83 and the return circuit 97. In this case, the check valve 99 facing the check valve 95
The hydraulic pump 39 does not drive the hydraulic motor 39 by applying the same hydraulic pressure to the oil supply circuit 103 communicating from the check valve 95 to the oil supply port 101 of the hydraulic motor 39 and the discharge circuit 107 communicating to the discharge port 105. Oil is circulated through the throttle portion 113 provided in the pilot control valve 111 of the parallel circuit 109, and the hydraulic motor 39 rotates slightly. The hydraulic motor 39 is linked to the drive roller 37 via the speed reducer 115. Next, set the solenoid valve 89 to A in FIG.
When switching from the position to the B position, the pressure oil is transferred to the cylinder 117.
Is operated to release the hydraulic brake 119, the pressure valve 121 is opened, and while the engine is running at low speed, the check valve 95 is returned to the oil tank 87 in the same manner as described above, and the hydraulic motor 39 does not rotate. Next, set the engine to high speed or use the main pump
When increasing the capacity of 83, the oil of auxiliary pump 85
When the flow rate from the discharge port 125 increases, the pressure rises, the pilot control valve 111 is automatically switched and closed, and the oil rotationally drives the hydraulic motor 39. When the solenoid valve 89 is returned to the A position, the oil in the cylinder 117 returns to the oil tank 87 and the hydraulic brake 119 operates to brake the hydraulic motor 39, and the hydraulic pressure is not sent to the hydraulic motor 39 as described above.

In the above configuration, when the vehicle 1 traveling on the ground is transferred to the monorail 21, the vehicle 1 is made to enter the auxiliary guide rail 77 from the entry end. The power of the engine is that the endless belt 11 is rotated by the drive sprocket 3 via the chain 59, the speed reducer 51, and the drive sprocket 3. The horizontal rollers 75, 75 on both sides of the vehicle 1 come into contact with the auxiliary guide rail 77 to correct the posture, and the positioning for engaging the guide rail 71 is performed. Next, when the auxiliary wheel 55 rides on the guide rail 71, the auxiliary wheel 55
Reducer 51 so that the peripheral speeds of 55 and drive sprocket 3 match.
Since the reduction ratio of is set, auxiliary wheel 55 and guide rail
No slipping between 71. The auxiliary wheels 55 are engaged with the guide rails 71 to correct and position the height and lateral postures thereof, and the front horizontal rollers 41, 41 engage and roll on both sides of the monorail 21 and engage with each other. While the pin 35 is engaged with the engagement hole 33, the driving roller 37 is driven by the driving of the hydraulic motor 39.
Rolls on the upper surface of the monorail 21. Subsequently, the rear vertical roller 25 rolls on the monorail 21 to support the rear part of the vehicle 1, and the horizontal rollers 27, 27 roll and sandwich both sides of the monorail 21. When the engagement pin 35 starts to engage with the engagement hole 33, the engagement pin 35 comes into contact with the end surface of the monorail 21 and the engagement position is positioned. Since the engagement pin 35 does not coincide with the engagement hole 33 because of the driving of No. 3, the drive roller 37 moves to a position where the engagement pin 35 coincides with the engagement hole 33 while stopping the rotation. At this time, the solenoid valve 89 is set to the B position and the hydraulic brake 119 is released, but the engine 79 is set to a low speed, and the oil of the auxiliary pump 85 passes through the main pump 83 and the pilot control valve 11.
Since it passes through the first throttle portion 113, the high pressure and low pressure circuits of the hydraulic motor 39 are communicated with each other by the throttle portion 113 of the pilot control valve 111, until the engagement pin 35 engages with the engagement hole 33. Even if the drive roller 37 is stopped in the meantime, high pressure oil is not applied to the hydraulic motor 39, and a large load is not applied to the drive roller 37 and the like. When the rotation speed of the engine 79 is increased at the position where the engagement pin 35 starts to engage with the engagement hole 33 or the capacity of the main pump 83 is increased, the hydraulic pressure on the discharge side of the main pump 83 rises and the pilot pressure increases. The control valve 111 is automatically switched and closed, and the hydraulic motor 39 starts to rotate normally.

〔The invention's effect〕

According to the present invention, when the vehicle enters the monorail, first, the auxiliary guide rail is used to correct the lateral position and the deviation of the approach angle, and then the guide rail is used to accurately determine the lateral position and the vertical position. Therefore, even if the entry position or the entry angle of the vehicle is greatly deviated from the monorail, the monorail can be easily moved without re-entering.

Particularly, since the vehicle body is guided along the auxiliary guide rails by the horizontal rollers provided on both sides of the vehicle body, not on the side surface of the moving parts of the traveling device such as ordinary wheels and crawlers, without damaging the traveling device, Accurate positioning is possible without sideways swinging of the vehicle body, and since the auxiliary wheels driven by the engine drive the vehicle on the guide rails, unlike the ground traveling device that pushes the vehicle body on the guide rails, There is no rocking and the drive wheels can be stably driven.
