矢印Ｅ方向へ移動する。 First, when the second drive device 23 is operated to extend the piston rod 23b, the loading platform 16 is lifted upward relative to the carrier body 11 as shown in FIG. 3 as a result of this extension. That is, in FIG. 1, when the piston rod 23b extends, the second drive device 2
Since the intersecting angle θ 1 between the first support rod 14 and the second support rod 19 that sandwich the transport vehicle body 1 widens, the angle θ 2 between the first support rod 14 and the base 6 of the carrier body 1 also widens, and therefore,
The total length of the first drive device 11 and the first support rod 14 is l 1
If the angle between the first support rod 14 and the base 6 after the piston rod 23b is extended is θ 2 ' as shown in FIG. 1 sin θ 2 <l 1 sin θ 2 , and the piston rod 23b becomes larger after being stretched. On the other hand, the cosine of the total length l 2 of the first driving device 11 and the first support rod 14 with respect to the angle θ 2 is l 1 cosθ 2 ＞l 1 cos
θ 2 ', and the piston rod 23b becomes smaller after being stretched. Therefore, the loading platform 16 is the carrier body 1
When lifted up against the first support rod 14
A first roller 15 installed at the tip of the roller moves in the direction of arrow C in the figure using first rails 17, 17 fixed to the loading platform 16 as a guide, and at the same time is installed on a second support rod 19 whose overall length does not change. The second roller 20 also moves in the direction of arrow E in the figure using the second rail 18 fixed to the base 6 as a guide.

時、前記のように第２駆動装置１１のピストンロ
ツド１１ｂを延伸して荷台１６と運搬車本体１の
ベース６との角度をθ2′−θ2″としておけば荷台
１６は水平線に平行に保たれていることになる。 Next, a case will be described in which the first drive device 11 is operated to extend or contract the piston rod 11b. For example, in the loading platform displacement device for a carrier shown in FIG. The intersecting angle θ 1 ' between the first support rod 14 and the second support rod 19 sandwiching the support rod 23 remains unchanged due to the presence of the second drive device 23. Furthermore, the distance from the intersection of the first support rod 14 and the second support rod 19 to the second roller 20 provided on the second support rod 19 is always constant, and the second roller 20 guides the second rail 18. As the piston rod 11b is extended, the angle between the first support rod 14 and the base 6 gradually becomes smaller. That is, when the loading platform 16 is parallel to the base 6 of the carrier body 1 as shown in FIG. 3, the angle between the first support rod 14 and the base 6 is θ 2 ', 1 in the state shown in Fig. 4 where 11b is extended.
If the angle between the support rod 14 and the base 6 is θ 2 ″, the loading platform 16 is inclined with respect to the base 6 by θ 2 ′−θ 2 ″. Therefore, as shown in Fig. 4, when the transport vehicle is on a slope B inclined by θ 12 ′ - θ 2 ″ with respect to the horizontal line A, and the front side of the transport vehicle (the side in the direction of arrow A in the figure) is facing downward. As mentioned above, if the piston rod 11b of the second drive device 11 is extended and the angle between the loading platform 16 and the base 6 of the carrier body 1 is set to θ 2 '-θ 2 ' ', the loading platform 16 will be kept parallel to the horizontal line. This means that

ド１１ｂを収縮することにより荷台１６を水平線
に対して保つことができるが、この場合の動作説
明は上記したピストンロツド１１ｂを延伸した場
合と同様であるので省略する。 On the other hand, when the transport vehicle is on a slope with the front side facing upward, the loading platform 16 can be maintained relative to the horizontal line by contracting the piston rod 11b of the second drive device 11. This is the same as when the piston rod 11b is extended, so a description thereof will be omitted.

つてもよい。 In addition, the method of rotating the tip of the first support rod 14 shown in the above embodiment by the first roller 15 using the first rail 17 as a guide, and the method of rotating the tip of the second support rod 19
The method of rotationally moving the tip of the first support rod 14 by the second roller 20 using the second rail 18 as a guide is not necessarily limited to this method. Alternatively, a moving method other than that in the embodiment may be used, such as having the tip of the second support rod 19 on the side equipped with the roller slide on this sliding portion in the above embodiment. Further, the traveling method of the transport vehicle is not limited to the crawler type of the embodiment, but may be a method using wheels or the like.
以上の説明からも明らかなように、この考案に

地においても荷台を水平線に平行に保つことがで
き、荷台の荷崩れを防ぐことができるとともに、

性及び便利さ等に利点を得ることができる。 As is clear from the above explanation, by using the device for displacing the cargo platform of a transport vehicle according to this invention, it is possible to keep the cargo platform parallel to the horizontal line even on a slope, and it is possible to prevent the cargo from collapsing on the platform.
Since the loading platform can be raised and lowered freely, advantages can be obtained in terms of stability and convenience in transportation work.
