動的に作用解除される状態で設けた運搬車に関する。[Detailed description of the invention] The present invention has two methods: dumping the cargo bed relative to the machine base in the front and rear directions around the horizontal axis that is almost horizontal, and dumping it in the left and right direction around the horizontal axis that is almost horizontal. A mechanism is provided to automatically fix the loading platform side plate, which is swingable around the horizontal axis on the upper end side in the dumping direction, in a closed position as the loading platform swings downward. The present invention relates to a transport vehicle that is provided in a state in which the action is automatically released as the vehicle moves.

。In order to selectively dump the cargo platform in three directions, conventionally,
Two sets of connecting structures having left and right axes and two sets of right and left connecting structures having front and rear axes are provided between the machine platform and the loading platform, respectively.
Two connecting pins are detachably attached to each of the two sets of connection structures, and only the side plate of the loading platform in the dumping direction is automatically opened and closed in conjunction with the up-and-down movement of the loading platform. The first loading platform side plate that swings in the front-rear direction and the second and third loading platform side plates that swing in the left-right direction are each provided with a mechanism for fixing and maintaining the closed state of the side plates, and the two connecting pins are At the same time as the dumping direction is selected by the attachment/detachment operation, the fixing/maintaining mechanism corresponding to the dumping direction is unlocked, resulting in extremely poor operability in setting the dumping direction.

なければ極めて不経済であった。In addition, in the fixing mechanism for the side plate of the loading platform that swings from side to side, the loading platform side plate is fixed and held in a biased state, and the flexibility is made to absorb the stroke difference of the stopper that fixes the side plate in conjunction with the vertical movement of the loading platform. However, since the cylinder with the flexible spring inside and the interlocking member are welded together, it is difficult to disassemble the flexible mechanism, and it is difficult to adjust the biasing force and stroke absorption. In the event that a breakage of a welded part occurs due to static noise and vibration, it would be extremely uneconomical to have to replace most of the accommodating mechanism.

たダンプ方向における荷台側板１６，１７，１８のみを
ダンプ操作に連動して自動的に開閉させられるようにな
り、三方向における荷台１３のダンプ操作を極めて操作
性良く行なわせられるようになった。In the side plate fixing mechanisms A, B, and C, by setting the shapes and positioning of the first to third cam floors 25, 39° 40 and the cams 24, 37, and 38 relative thereto, no human operation is required. Only the loading platform side plates 16, 17, and 18 in the selected dumping direction can be automatically opened and closed in conjunction with the dumping operation without any need, and the dumping operation of the loading platform 13 in three directions can be performed with extremely high operability. It became so.
