2. Description of the Related Art When a railroad vehicle derails, the only way to return it to its original position is to wait for the crane vehicle to be dispatched. This is because the distance between the abdominal surface of the vehicle and the ground surface is small, and no suitable device that can be inserted between them is found. If the guide wheel is damaged by derailment, the crane truck must be used to transfer it to the nearest depot. In either case, the track is blocked for a long time. There has been a strong demand for using a small member that can be carried by a vehicle such as a railroad vehicle or a truck, and assembling it in a small space under the vehicle so that it can be returned or temporarily transferred.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 and 2, a railroad vehicle has front and rear guide wheels C and D made of iron in addition to front and rear wheels A and B made of rubber. The guide wheels C and D are retracted upward, and the rear wheels B are driven to travel on the road. At the center of the vehicle, there is provided a turntable E capable of turning up and down and a drive device for the turntable E. When traveling on the rail,
The guide wheels C and D are lowered. Front guide wheel is vehicle front wheel A
Or the rear guide wheel travels in a state where the rear wheel B of the vehicle comes into contact with the rail and is drivable. It is assumed that the railroad vehicle derails to the left of the rail R as shown in FIG. Pull up the turntable E to the vicinity of the upper limit, and insert the inclusion k1 below. Next, lower the turntable E to the lower limit and lift the front and rear wheels A and B.
Insert k2 underneath. The inclusion k1 is removed to create a small space under the car. The lifting stroke of the turntable E is about 35 cm at most.

In this space, the guide frame 1 and the boat body 2 are inserted onto the lower rails of the turntable E. As shown in FIGS. 4 to 7, the guide frame 1 is formed by connecting the long member 1a and the short member 1b to each other in an L shape with bolts 1e, inserting them from left and right under the vehicle, and integrally assembling them. It is designed to have an appropriate extension length by passing it between both rails. FIG. 7 shows a connecting portion when the L-shaped member is assembled into a rectangle. A flanged retaining ring 1c is projected from the end of the long member of the L-shaped member, and is fitted into a retaining hole 1d of the end of the short member to prevent the stopper from coming off. On one short member 1b, an opening 1f is provided at the center and a central through hole (not shown) is bored. The screw rod 3 has a handle 3b fixed to one end thereof and is rotatably supported by the screw block 3a. Screw block 3a
Can be detachably fitted into the opening 1f. The mounting is fixed by the fixing pin 1g. Vessel 2 is long and short member 2
It is composed of a rectangular frame body a and 2b, and the long side member 2a is attached to the guide frame 1
It is possible that the rollers 2c of each short side member roll on the long member 1a of the guide frame 1 while being guided and positioned inside the long member 1a. One short side member 2b of the boat body 2 has a through hole at the center, and a screw rod 3 is screwed into a nut 2d fixed to the inside of the boat body 2 to rotate the handlebar 3 in a direction perpendicular to the rail. It is possible to move back and forth. Rolling stand E for derailed vehicles
The vehicle can be re-run by placing it on the boat 2, returning it to its original position by operating the screw rod 3, and removing the guide frame and the boat.

If the guide wheel is damaged by derailment,
First, the vehicle is returned to its original position by the above-mentioned method, the broken guide wheel is separated from the rail, and then the front and rear wheels A and B are put on the emergency vehicles F and M, respectively. As shown in FIGS. 8 to 11, the front wheel receiving wheel F is formed into a rectangular shape by inserting the parallel pins 4a at both ends of the two temporary shafts 4 into the corresponding locking holes 5a of the side plate 5 and fixing them by the pins 5b. It is a thing. A guide wheel 6 is rotatably supported on the temporary shaft 4 at a position corresponding to each rail,
A front wheel support plate 7 is attached to the corresponding position of the rubber front wheel A of the vehicle, and is raised so that the lower surface of the front wheel A does not come into contact with a railroad crossing or the like. The front wheels A are lifted up and the guide wheels 6 alone drive the vehicle.

As shown in FIGS. 12 to 14, the emergency vehicle M for the rear wheels has side plates 9 on both ends of the two temporary shafts 8 as in the case of the front wheels.
It is also the same as that in which the guide wheel 10 is rotatably supported by the temporary shaft 8 in the form of a square fixed by fixing. However, since the side plate is inside the guide wheel, a U-shaped notch 9a is formed so that it can be fitted into the U-shaped block 8a of the temporary shaft 8 from above, and each of them has a pin 8b.
To fix. A guide roller 9c is rotatably attached to the outside of the side plate 9 so as to be rotatable. Further, the side plate 9 is provided with a convex piece 9b at the center of the upper surface. First, the side plate 9 is attached to the temporary shaft 8 on the opposite side of the guide roller so that the guide roller 9c can be mounted in a U-shape so that the guide roller 9c can be mounted on the rail and transferred from the rear of the vehicle. Then, another temporary shaft 8 is attached at the front position of the rear wheel. There are springs S on both sides of the lower surface of the rear axle housing of the vehicle, which are locked by spring receiving plates K.
Is in contact with the spring receiving plate K and is integrated with the rear axle housing and the emergency receiving vehicle M.
