FIG. 1 is a front view partially showing an example of the derailment recovery device of the present invention, and FIG. 2 is a side view thereof. Four vehicle moving devices 2 as shown in FIG. 1 and FIG. 2 are arranged at lower portions on both front and rear sides of the track maintenance vehicle 1. The wheel moving device 2 has a jack means 3 and a horizontal moving means 4 which is moved up and down by the jack means 3. A main body base 5 and a reinforcing member 6 are coupled to the lower portion of the track maintenance vehicle 1, and the horizontal moving means 4 and the lower portion of the track maintenance vehicle 1 are connected via these. In addition, 7 is a wheel of a track maintenance vehicle, and 8 is a rail.

FIG. 3 is an enlarged front view of the vehicle moving device 2 portion in FIG. 1 (and FIG. 2), and FIG. 4 is a sectional view taken along line AA. As the jack means 3, for example, a hydraulic jack is used, and a base plate 11 for stably standing the jack means 3 on the ground such as a track is provided at the tip of an output portion (piston rod) 10 protruding from the lower end of the cylinder 9. It is provided. Further, a pair of hydraulic pipe connecting portions 1 are provided on the side surfaces of the cylinder 9.
2 and 13 are provided, which are connected by a hydraulic hose 14 to a hydraulic circuit (not shown) provided in the track maintenance vehicle. A turning means 15 is attached to the upper end of the cylinder 9 of the jack means 3, and the horizontal moving means 4 is connected to the turning means 15. The turning means 15 is a bearing 1 provided on the lower surface of the block 16 in the horizontal moving means 4.
7, a swivel plate 18 that is pivotally supported, a pin engaging portion 19 provided between the tip of the swivel plate 18 and the lower surface of the block 16, and each pin hole of the pin engaging portion 19, It has a pin 20 for engaging and locking the tip of the block with the block 16.

The horizontal moving means 4 has a hydraulically operated cylinder 21, a bracket 23 connected to an output portion (piston rod) 22 of the cylinder 21 by a pin, and a guide rail 24 fixed to the track maintenance vehicle side. As shown in FIG. 4, the rail 24 has a pair of guide portions 26 each having a groove 25 on the outer surface on both sides.
6 is slidable along a groove 27 provided on the upper surface. The groove 25 is engaged with the protrusions 28 provided on the inner surfaces of both sides of the groove 27. A pair of connecting brackets 29 having a space for fitting the cylinders 21 are provided at the center of the upper portion of the block 16, and the cylinders 2 are inserted into the holes 30 of the connecting brackets 29 through the pins 31.
The outer periphery of 1 is connected to the block 16. The cylinder 21 is connected to a hydraulic circuit provided in the track maintenance vehicle 1 by a hydraulic hose (not shown).

To explain the operation of the above device, when the track maintenance vehicle 1 travels normally on the track, the pin 20 of the turning means 15 is pulled out to move the jack means 3 clockwise from the state of FIG. 4 as an example. The cylinder 9 is turned 90 degrees and the cylinder 9 portion is held horizontally on the vehicle side through a locking means (not shown). When, for example, the front wheels of the track maintenance vehicle are derailed, first, as shown in FIG. 1, appropriate support blocks 32 and the like are placed on the tracks outside the left and right front wheels 7 that have been derailed. At the same time, the cylinder 9 is unfixed on the vehicle side and the jack means 3 is turned counterclockwise to make it vertical as shown in FIG. 1 and then the pin 20 is inserted into the pin hole of the pin engaging portion 19 to turn the turning means 15. Lock it. Next, the hydraulic pressure of the cylinder 9 is operated to extend the output unit 10 as indicated by the arrow, and the tip of the output unit 10 is brought into contact with the support block 32.

After the jack means 3 to be used is brought into the above-mentioned state, the vehicle moving device 2 is operated synchronously in the following manner so that the left and right derailed wheels are simultaneously returned to the rails. That is, first, the cylinders 9 of the left and right jack means 3 are
The hydraulic circuit is operated to further extend the output section 10, and the track maintenance vehicle 1 is lifted until the lower part of the derailed wheel is positioned higher than the rail. Next, the left and right horizontal moving means 4
The hydraulic circuit of the cylinder 21 is operated to horizontally move the track maintenance vehicle in the width direction until the derailed wheels 7 are positioned on the rails 8, and then the hydraulic circuits of the left and right cylinders 9 are operated again.
The wheels 7 are returned to the rails 8 by retracting the output unit 10. Further, when the rear wheels are also derailed, the above operation for lifting the track maintenance vehicle and the following operations are repeated for the rear parts. After the derailment of the track maintenance vehicle is recovered by the above-mentioned operation, the hydraulic circuit of the cylinder 9 is operated to retract the output portion 10 thereof, and the pin 20 is again engaged with the pin engaging portion 1.
Then, the cylinder 9 is swung clockwise and fixed to the track maintenance vehicle side. It should be noted that the turning means 15 can be omitted, and in that case, of course, these turning operations do not exist.

In the above example, the driving method of the jack means 3 and the horizontal moving means 4 is performed by a hydraulic cylinder, but either one or both may be another driving method, for example, a pneumatic driving method or an electric driving method. . In addition, since the left and right derailed wheel parts are lifted and moved horizontally,
The left and right jack means 3 and the horizontal movement means 4 are operated in synchronization, but this operation can be achieved by using a hydraulic circuit common to the left and right. Furthermore, by installing a sensor that detects the left and right inclination of the track maintenance vehicle on the vehicle and providing a controller that controls the hydraulic circuit so that the difference between the signal and the normal posture is minimized, the balance of the track maintenance vehicle can be more accurate. It can be operated synchronously while maintaining.
