The three container holding members 33 provided and the container mounting portions 3 on the left and right sides are connected to each other, and the upper and lower frames 23c of the connecting frame 22 and the guide frame 23 are slidably contacted with each other to prevent the elevating frame 31 from shaking. It is composed of a connecting plate 34 and a guide wheel 35 which is provided below the vertical frame 31d on the rear side and rolls on the front side surface of the guide column 23b.

The container mounting section 3 includes the lifting frame 31 as a whole.
The upper part is provided in a state of being tilted toward the guide frame 23 side by about 3 degrees with respect to the vertical direction, and the container mounting plate 32 provided vertically to the elevating frame 31 has a tip side of about 3 with respect to the horizontal direction. It has been raised. Therefore, when the gas container 4 is mounted on the container mounting portion 3, the gas container 4 leans toward the elevating frame 31 side, and the body of the gas container 4 holds the holding recess 33a provided in the container holding member 33. Will be held in

The elevating device 5 for elevating and lowering the container placing part 3 includes a hydraulic jack 51 provided on the upper surface of the upper end of the upper frame 23c of the guide frame 23 and an auxiliary device extended from the upper rear side of the guide frame 23. The support column 52 is composed of a support column 52 and a link 53 that connects the upper end of the auxiliary support column 52 and the rear upper part of the elevating frame 31 of the container mounting section 3.

That is, by operating a jack up lever (not shown) to extend the hydraulic jack 51, the link 53 is rotated around the connecting point 53a on the auxiliary support column 52 side, and the link on the upper end side of the elevating frame 31 is connected. The point 53b is configured to move upward to lift the container mounting portion 3. Further, when lowering the container mounting portion 3, the hydraulic jack 51 is contracted by the weight of the container mounting portion 3 by operating a pressure release valve (not shown) of the hydraulic jack 51, and the container mounting portion 3 is , Descend until its lower end touches the ground.

Here, as described above, by setting the operating point of the elevating device 5, that is, the connecting point 53b on the rear side of the elevating frame 31, the container mounting portion 3 is lifted at the connecting point 53b. From the relationship with the center of gravity of the container placing part 3, the container placing part 3 has a force that causes the lower part to rotate backward about the connecting point 53b (clockwise force in FIG. 1). ) Occurs. Then, this force becomes a force for pressing the guide wheel 35 against the guide column 23b.
Therefore, the container placing portion 3 is in a form of being supported by the connecting point 53b and the guide wheel 35.

As described above, the container mounting portion 3 is hung on the upper side of one side, so that the container mounting portion 3 can be used when the container mounting portion 3 is empty or when the gas container 4 is mounted. Since a force in the same direction can always be generated in the lower part of the container 3, only by providing the guide ring 35 between the lower one side of the container mounting part 3 and the guide column 23b, the container mounting part 3 can be kept in a stable state. You can raise and lower with.

For example, an elevating device may be provided in the center of the container placing part 3, but in this case, the gas container 4 is placed on the front side of the container placing part 3 or on the rear side thereof. Since the front-rear balance is lost depending on the placement, it is necessary to provide guide means on both the front and rear sides. However, by configuring so that the turning force in a constant direction is always generated as described above, one guide wheel 35 is provided. Only by providing the container mounting portion 3, it is possible to smoothly move up and down.

When the gas container 4 is transported by the container transport vehicle according to the present embodiment, first, the depressurizing valve of the hydraulic jack 51 is operated at the gas container mounting location to lower the container mounting portion 3 to move the container. After the bottom of the mounting plate 32 is grounded, the predetermined gas container 4
Are transferred onto the container mounting plate 32. At this time, the gas container 4
Is leaned to the side of the elevating frame 31 due to the inclination of the elevating frame 31 and the container mounting plate 32, so that it is fixed by a chain or a belt if necessary. The type of gas container to be mounted is not particularly limited, and almost any gas container that is normally distributed in the market can be mounted. The elevating frame 31 and the container mounting plate. Due to the inclination of 32 and a plurality of container holding members 33 provided at appropriate places, even a short gas container can be reliably held.

Next, the jack up lever is operated to extend the hydraulic jack 51 and raise the container mounting portion 3. At this time, the horizontal position of the container mounting portion 3 is held by the concave groove portions 34a of the upper and lower connecting plates 34 slidingly contacting the connecting frame 22 and the upper frame 23c, respectively, and the front-back direction is as described above. The guide wheel 35 is held by rolling on the surface of the guide column 23b.
