DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred first embodiment of a railroad vehicle for welding work according to the present invention will be described below in detail with reference to FIGS. In the railroad vehicle A for exclusive use of welding, the fixed-length rail conveyed to the construction site is made into a long rail which is the temporary track 50a mainly by gas pressure welding at the side of the track, and after the main line is laid, both ends are mainly joined by thermite welding. This is a vehicle on which a welding device is loaded and what is needed at the site is unloaded from the vehicle to perform the welding operation.

The railroad vehicle A for welding work according to the present invention includes, in addition to the tires 11 and 12 for traveling on a general road, track wheels 13 and 14 for traveling on a track 50 and a body of the railroad vehicle for lifting and rotating. And a lifting support device 3 provided at the center of the lower surface of the vehicle body for use in changing the direction of the vehicle, placing the vehicle on the track, and removing the vehicle from the track. Rail-car A is small,
Iron wheels 13 and 14 are attached to the front and rear and left and right sides of the vehicle body by iron wheel overhanging mechanisms 16 and 17 so that they can be easily stored and transported anywhere, based on a medium-sized truck. It should be noted that an idle roller 15 is interposed between the rear iron wheel 14 and the rear wheel 12 to transmit the torque of the rear wheel 12 to the iron wheel 14 in the same rotation direction. Rear wheel 12 and idle roller 15

[0028]

As described above in detail, the railroad vehicle for welding work according to the present invention has the following effects.

The equipment and devices for welding work are collectively transported to the rail laying site by using the track, the large equipment is placed in the vehicle, and only the necessary equipment and equipment required at the site are moved down the rear door of the rail-land vehicle. It can be lowered horizontally, taken out of the vehicle with a trolley, and installed on site from the vehicle side via cables, pipes, hoses, etc., so the preparation for welding work and cleaning up can be greatly reduced,
Further, the labor for installation can be greatly reduced.
In addition, the track can be used every time the welding location is moved, so that the track-land vehicle, the bogie, and the rear door that also serves as the bogie can be moved each time.

Since all the devices, tools and equipment necessary for the welding operation can be stored in the light van, it is easy to manage welding tools without leakage.

When the rear door descends, rises and rises in a horizontal posture, a heavy object can be easily moved from the track-and-land vehicle to the outside of the vehicle to the track or site. Conversely, it can be easily mounted on a railway land vehicle.
