  In the case of the above-mentioned transport truck with crane, the crane apparatus must be arranged in one side direction of the truck because of securing the loading place, etc. According to this, it is arranged on both sides, and a relatively long track material such as a reaction plate is loaded on the loading platform of the cart, and it is wholesaled to the side when it is loaded at the destination (the left side if it is the left side of the cart). Therefore, in order to move the loaded and unloaded items into the track, it is necessary to remove the unloaded items from the place where the long items are located. After that, it must be done using a lifting device such as Yamakoshi. In other words, for example, long objects that have been installed in the track and have become unnecessary due to deterioration are moved from the track to the track, and those required are moved from the track to the track. Need.

  The present invention is one of the long objects, for example, reaction plates can be directly unloaded from the loading platform into the track, and the reaction plates in the track can be loaded onto the loading platform. It was devised for the purpose of providing a relatively long track material carrier that can be omitted.

  For example, a carriage that transports track materials such as a reaction plate formed by overlapping a back plate and a cap on the substrate having a substantially cross-sectional groove-like bracket in which leg pieces are provided on opposite sides of the substrate. A platform frame comprising a platform covering the center of the platform in the width direction and left and right legs supporting the platform on a platform supported by wheels traveling on the rail, And a crane device for loading and unloading the track material in which the suspension material at the tip of the telescopic boom extends from the rear end of the load bed is provided on the platform. It is a basic means that a mounting portion dedicated to the track material is provided between the legs.

  In this basic means, in the case of the reaction plate mounting portion, a group of receiving rollers for receiving one leg piece of the bracket arranged side by side in the front-rear direction of the loading platform, and for receiving and receiving the other leg piece A carriage that can efficiently handle the reaction plate on the loading platform by adding a point that is provided with a group of receiving rollers and that allows the reaction plate to be received and supported by the receiving roller of the mounting portion. In the case of the rail mounting portion, a group of receiving rollers for receiving and supporting the rail are arranged in the front-rear direction of the loading platform, and the rail is supported by the receiving roller of the mounting portion. By adding the points, it is possible to provide a cart that can efficiently handle rails on the loading platform.

  According to the present invention, since the crane device is located in the middle of the gauge of the loading platform that runs on the track rail, the loading and unloading work of the track material related to the inside of the gauge is performed using the crane device ( Therefore, a cart that can smoothly perform the next stage work on the track material for loading and unloading articles can be provided.

  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 and 8 which are adjacent to each other at the tip 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.
