  The drawings show an embodiment of a transport cart of the present invention. The embodiment is a reaction cart or a rail transport cart that travels along a track rail using a power vehicle as a power source. Although the applied embodiment is shown, there is no inconvenience even if the present invention is applied to a self-propelled carriage.

  In the reaction plate B, a back plate 81 and a cap 82 are overlapped on the substrate 80a of the bracket 80 having a substantially groove-like cross section in which leg pieces 80a 'and 80a' are relatively provided on opposite sides of the substrate 80a. However, the transport vehicle of the embodiment can also be applied to transporting only the bracket 80 in which the back plate 81 and the cap 82 are omitted from the reaction plate B. Conveying the reaction plate B in which the back plate 81 or the like and the bracket 80 are integrated has an advantage that the on-site assembly work of the reaction plate B can be omitted.

  The transport cart A according to the embodiment (the transport object according to the present invention is applicable not only to the reaction plate B and the rail Ra but also to transport of a relatively long track transport material) and an appropriate number of wheels 1 traveling on the track rail R. ,... Are arranged on the upper surface of the loading platform 2 arranged side by side in the left-right direction of the loading platform 2, and the middle portion in the front-rear direction of the loading platform 2 is separated from the loading platform 3. A base frame 4 consisting of a leg 4b erected on both sides and a base 4a supported across the left and right legs 4b is erected, and a crane device 5 is mounted on the base 4a of the base 4 It is provided.

  The mounting portion 3 includes a pair of support members 6 each having an L-shaped cross section composed of a fixed piece 6a and an upright piece 6b. The fixed portions 6a are fixed to the upper surface of the loading platform 2 and arranged side by side. A support roller 8 is supported at both ends (on the outer surface side of the stand-up piece 6b) of the support shaft 7 through and supported by the stand-up piece 6b. The reaction plate B is movably mounted on the leg support pieces 80a ′ and 80a ′ on the cylindrical support roller 8 having a flange 8a at the base portion on the side.

  In the crane apparatus 5, the suspension member 5b provided at the tip of the boom 5a can be moved to both side end positions in the juxtaposition direction of the placement units 3, 3,... Arranged in parallel with each other. The reaction plate B which has a turning function and is held by the suspension member 5b is retracted to a position where it is detached from the upper surface 2a of the loading platform 2 due to the expansion and contraction of the boom 5a, or is expanded and contracted to the position where it is removed and lifted. It has a function that can be moved up to 2. That is, the crane device 5 is configured to be able to move between the loading platform 2 and the road bed in a state where the reaction plate B can be held horizontally.

  In the drawing, reference numeral 11 denotes a hydraulic unit for the crane device 5, which is raised on the platform 40 and provided on the loading platform 2 in the same manner as the crane device 5.

  At the time of loading operation, the reaction plate B is assembled to the suspension member 5b of the crane apparatus 5 and moved to the loading platform 2 side (FIG. 5). When reaching the limit position of the movement, the reaction plate B is separated from the suspension member 5b. The loading work state is finished by manually pressing the reaction plate B partially fitted in the placement portion 3 and pushing it into the placement portion 3 using the rolling of the support roller 8 (FIG. 7). (In the embodiment, four reaction plates B are transported), and this state is maintained by a stopper device (not shown).

  In addition, when loading and unloading, a part of the reaction plate B is manually protruded from the mounting portion 3 by using the rolling of the support roller 8, and the crane member 5 is combined with the hanging material 5 b in the protruding portion. The plate B can be wholesaled in the space between the track rails R.

  The reaction plate B is supported on the receiving roller 8 group by utilizing the relationship between the pair of receiving rollers 8 and 8 opposed to each other at the base portion of the mounting portion 3 on the flange 8a side. As shown in FIG. 10 and FIG. 11, in the case of the rail Ra, it is supported by the group of receiving rollers 8 using the relationship between a pair of receiving rollers 8, 8 adjacent to each other at the tip, and the mounting portion 3 is placed.

  Then, as in the case of the reaction plate B, at the time of loading operation, the rail Ra is lifted by being assembled to the suspension member 5b of the crane apparatus 5 and moved to the loading platform 2 side. 5b, the rail Ra partially fitted into the mounting portion 3 is manually pressed and pushed into the mounting portion 3 using the rolling of the support roller 8 to complete the loading operation state ( In the embodiment, the three rails Ra are transported when the length is substantially the same as the reaction plate B), and this state is maintained by a stopper (movement prevention) device (not shown). .

  Further, when unloading, a part of the rail Ra is manually protruded from the mounting portion 3 by using the rolling of the support roller 8, and the crane device 5 is assembled by combining the hanging material 5 b with the protruding portion. By operating the rail Ra, the rail Ra can be wholesaled between the rails of the track rail R.
