As a result, for example, the standby place of the transport vehicle 10 in the maintenance factory can be reduced.

( Embodiment )
A transport vehicle according to an embodiment of the present invention is shown in FIG. The difference from the reference example is that a turntable (steering means) is also provided in a vehicle portion on which the rear portion of the railway vehicle body S is mounted.

The vehicle portions 110a and 110b of the transport vehicle 110 have substantially the same configuration as the vehicle portion 10a of the transport vehicle 10 of the reference example .

The difference between the vehicle portion 110a and the vehicle portion 10a of the reference example is that a link arm 130a extending from one wheel 114a side of the base 118a toward the vehicle portion 110b is provided.

On the other hand, the vehicle portion 110b is configured by removing the traction tool 26 from the vehicle portion 10a of the reference example , and further includes a link arm 130b extending from the other wheel 114b side of the base 118b toward the vehicle portion 110a. The turntable 124b is the same as the turntable 26 of the reference example .

  The link arm 130a of the vehicle portion 110a and the link arm 130b of the vehicle portion 110b do not face the parallel direction 132 of the vehicle portion 110a and the vehicle portion 110b, but face each other so as to intersect the parallel direction. The link arms 130a and 130b are connected by a link bar 134.

  As shown in FIG. 8, the link arms 130 a and 130 b have joint holes 140 a and 140 b at their tips, and the joint holes 140 a (140 b) are inserted into joint pins 142 provided at both ends of the link bar 134. . The joint pin 142 is rotatable in the joint hole 140 and is detachable. This is because, when the link bar 134 and the link arm 130a (130b) are always connected, the standby position of the transport vehicle 110 becomes large. When the transport vehicle 110 is not used, the link bar 134 is connected to the link arm 130a (130b). ).

  As shown in FIG. 9, for example, when the base 118a of the vehicle portion 110a rotates clockwise about the rotation axis CLa, the link bar 134 is pushed toward the vehicle portion 118b via the link arm 130a, thereby The base 118b of the vehicle portion 110b is rotated counterclockwise about the rotation axis CLb. That is, when a steering angle is given to the wheel 114a of the vehicle part 110a, a steering angle is also given to the wheel 114b of the vehicle part 110b.

According to the transport vehicle of this embodiment, since the steering angle can be given to the wheel of the vehicle portion on which the rear portion of the railway vehicle body is placed, the turning radius is smaller than that in the reference example during transportation of the rail vehicle body. You can turn.

Having described the present invention by way of embodiments, the present invention is not limited thereto.

  For example, in the above-described embodiment, the steering means is a turntable, but the present invention is not limited to this.

FIG. 10 and FIG. 11 show a reference example of the steering means, and the vehicle portion 210a of the transport vehicle on which the front portion of the railway vehicle body is mounted has a steering mechanism similar to the steering mechanism of the automobile.

  More specifically, each of the two wheels 214a of the vehicle portion 210a is supported by a base 218a integral with the loading platform 212 via a knuckle arm 250. The two knuckle arms 250 are respectively supported at both ends of the base 218a so as to be rotatable about a rotation axis CL2 extending in the vertical direction.

  Further, the traction tool 226 of the vehicle portion 210 a is attached to the movable base 252. The movable base 252 is supported so as to be rotatable around a shaft 254 that extends in the vertical direction and is attached between the loading platform 212 and the base 218a.

  The other end of a tie rod 256 having one end connected to the knuckle arm 250 is connected to the opposite side of the movable base 252 to which the traction tool 226 is attached. The other ends of the two tie rods 256 are connected to the base 252 so as to face each other with the movable base 252 interposed therebetween.

  According to such a configuration, as shown in FIG. 12, when the movable base 252 is rotated about the shaft 254 via the traction tool 226, the tie rod 256 rotates the knuckle arm 250. As a result, a steering angle is given to the wheel 214a.

  Moreover, in the above-mentioned embodiment, since two vehicle parts of a conveyance vehicle are two wheels, they cannot become independent. As a countermeasure, each auxiliary vehicle may be provided with a removable auxiliary wheel.

For example, FIG. 13 and FIG. 14 show a case where the vehicle portion 10b of the transport vehicle 10 includes auxiliary wheels, taking the reference example as an example . FIG. 14 is a cross-sectional view of the vehicle portion 10b as viewed from the direction C shown in FIG.

  As shown in the figure, the vehicle portion 10b includes two mounting pins 360 extending in the vertical direction for mounting the auxiliary wheels on the loading platform 12b. The two attachment pins 360 are provided in each of the front part and the rear part of the cargo bed part 12b.

  Each of the two auxiliary wheels 362 has a mounting hole 364 inserted into the mounting pin 360 at one end and a wheel 366 at the other end.

  When two auxiliary wheels 362 are attached to the vehicle portion 10b, the vehicle portion 10b becomes a four-wheel vehicle and can run independently. Further, after the vehicle portion 10b places the railcar body and is fixed to the loading platform 12b, the auxiliary wheel 362 can be removed to secure a large work area for the worker (the auxiliary wheel 362 allows the worker to work). Will not be disturbed.)

  As described above, according to the present invention, the standby place of the transport vehicle that transports the railway vehicle body becomes small. Therefore, there is a possibility of being suitably used in a field related to the railway vehicle body, for example, a manufacturing field, a transportation field, or a maintenance field.
