It is a side view of the truck for rail vehicles of FIG. It is explanatory drawing of the state which mounted the gauge land vehicle on the trolley | bogie.

An embodiment of the present invention will be described based on the drawings.
The transport carriage 1 of this embodiment is for transporting the railcar 21 shown in FIG. The track and land vehicle 21 is configured based on a truck vehicle, and can travel on the road by tire wheels (wheels for road travel) 22 attached to four places in the front, rear, left, and right of the vehicle body. Further, a track traveling device 23 having iron wheels 24 for traveling on the track R is attached to four places in the front, rear, left, and right of the vehicle body. The track traveling device 23 is bent and stretched by hydraulic drive, and pushes up the vehicle body so that the tire wheel 22 is lifted when the iron wheel 24 is disposed on the track R. At the center of the lower part of the vehicle body, a rolling stock 25 is mounted for transferring and moving the rail vehicle 21 onto the rails. The rolling stock 25 can move up and down by hydraulic drive, push up the vehicle body at the time of descent, and horizontally turn the pushed up vehicle body by motor drive or manually. The rolling stock 25 is provided with ground plate portions 26 which respectively form stepped portions and project downward at the front and back of the lower surface thereof.

  In FIG. 1 to FIG. 3, the carriage 1 has a pair of left and right carriage bodies 2 respectively mounted on a pair of parallel tracks R, and front and rear to connect between these two carriage bodies 2 at their front and rear A pair of connecting pipes 3 are provided.

  The bogie main body 2 includes a gantry 4, a pair of front and rear wheels 5 pivotally supported on the gantry 4 by an axle 11, and a pedestal 6 fixed on the gantry 4. The gantry 4 includes a pair of left and right side plates 7, a horizontal support plate 8 connecting between the upper edges of the side plates 7 at the middle in the front-rear direction, and a vertical connecting both plates 7 And a directional coupling plate 9,10.

  The pedestal 6 is fixed on the support plate 8. The pedestal 6 has an engaging recess 6a fitted to the ground plate portion 26 at any of the front and rear of the rolling stock 25 and a bottom surface 6b of the engaging recess 6a, that is, a support surface on which the grounding plate 26 of the rolling stock 25 is mounted.

  The connecting pipe 3 is inserted into the connecting shaft 12 and is prevented from coming off by a retaining pin 13 penetrating these in the orthogonal direction.

  The transport carriage 1 according to this embodiment is stored on the track and truck 21 in a state of being disassembled into four parts consisting of two carriage main bodies 2 and two connection pipes 3. When traveling by a pair of iron wheels 24 before or after the rail vehicle 21 becomes impossible due to a derailment accident or the like, as shown in FIG. 4, the rolling stock 25 is placed on the transport carriage 1 to move the rail vehicle 21 to the evacuation location. . In this case, first, the transport carriage 1 disassembled and stored on the track truck 21 is carried out and assembled. Next, the ground wheel 21 is pushed up and inclined by a jack (not shown) so that the broken iron wheel 24 of the ground wheel 21 floats on the track R and the other normal pair of tire wheels 22 is lowered on the track R. An attached outrigger (not shown) can be used as the jack. Next, the transport carriage 1 is disposed on the track R at the lower position of the rolling stock 25. At this time, the slope 6 b of the pedestal 6 corresponds to the inclination of the ground contact plate portion 26 of the rolling stock 2. Next, the rolling stock 25 of the rail vehicle 21 is lowered, and the ground contact plate portion 26 is placed on the slope 6 b of the pedestal 6. Next, the jacks are contracted, and the load of the track / truck 21 is made to bear on the transport carriage 1 in a state where the required inclination of the track / truck 21 is maintained. In this state, the track truck 21 is moved by the transport truck 1 to the nearest evacuation location by a method such as self-force or traction.

  The transport carriage 1 supports the rolling stock 25. Therefore, even if the broken iron wheel 24 is deformed, the ground vehicle 21 can be reliably and stably carried and received, and can be transported safely. Since the base 6 has the front and rear direction slopes 6b, the unreachable broken iron wheel 24 floats on the track R, and the normal iron ring 24 on the opposite side to the front and rear falls on the track R. The vehicle body can be supported by being inclined in the front-rear direction. As a result, the load applied to the transport carriage 1 can be halved, so that the size and weight of the transport carriage 1 can be reduced.
