DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 2 shows an example of a truck with a removable bed according to the present invention.

The illustrated truck includes a chassis 10 and a container tank 11 (“packing platform” in the present invention) mounted on a chassis body 10 a having a horizontally long rectangular frame shape.

As shown in FIGS. 3 and 4, the container tank 11 is a horizontally long tank with a frame, and is formed by mounting a tank 13 and the like on a container frame 12.

The tank 13 is formed by a body 13a and mirrors 13b and 13c before and after the body 13a, and contains a chemical such as sodium hypochlorite therein. Then, as shown in FIG. 2, the rear portion of the container frame 12 is detachably attached to the chassis body 10a by tightening with a fastening member 15. The tightening fitting 15 is, for example, a twist lock device conforming to a marine container standard, and rotates the lever 15a to tighten the container frame 12 to the chassis body 10a as shown in FIG.

As shown in FIG. 3 and FIG. 4, four arms 20 are provided below the floor of the container tank 11, that is, before and after the lower side of the container frame 12, in a direction orthogonal to the longitudinal direction of the container frame 11. Attach. The arms 20 are installed horizontally so that they can be pulled out to the outside of the chassis body 10a.

A support leg 25 is connected to the tip of each of the arms 20 so as to be rotatable in a range of approximately 90 degrees. The support leg 25 is formed to be slightly longer than the height of the chassis body 10a using, for example, a square pipe. When not in use, the support leg 25 is folded over the container frame 12 and stored in a horizontal storage position.

On the other hand, the chassis main body 10 a includes an elevating device for elevating and lowering the container tank 11, although not shown. The lifting device is, for example, of a hydraulic drive type using a battery, and has a structure in which the container tank 11 is raised and lowered via four cylinders on the chassis body 10a.

In this case, the above-mentioned detachable type truck has a configuration in which a plurality of container tanks 11 similar to those described above are arranged for one chassis 10 in this example.

When the cargo is transported by the above-mentioned truck with a removable carrier and the cargo is unloaded at the destination, the container tank 11 is detached from the chassis 10 and separated.

At this time, after the mounting of the chassis 10 and the container tank 11 by the tension fittings 15 is removed, the container tank 11 is once raised by operating the elevating device. Then, first, the arms 20 are manually pulled out from the storage positions one step forward, respectively, and the support legs 25 are protruded to the outside of the chassis main body 10a as shown by the dashed line in FIG. 6, and then the support legs are lowered. After turning about 90 degrees and hanging down, the arm 20 is further pulled out as shown by the solid line, and the supporting leg 25 is locked by the automatic locking device (not shown) at the hanging position.

Thereafter, the container tank 11 is lowered by the elevating device, the four support legs 25 are grounded, and the container tank 11 is supported by the support legs 25. Then, the chassis 10 is driven to move forward from below the container tank 11, and the container tank 11 is separated from the chassis 10 as shown in FIG. Then, the unloading for extracting the chemical from the container tank 11 is performed.

At this time, when the illustrated truck is used, in this example, after the container tank 11 is separated, only the chassis 10 is driven immediately after returning to the transportation source without waiting for the unloading operation. Then, the container is loaded with the chemical liquid in advance at the transportation source, and the container tank 11 supported and supported by the support legs 25 as shown in FIG. 1 is mounted on the chassis 10 and delivered to the destination again. I do.

When the container tank 11 is mounted on the chassis 10, the chassis 10 is driven to move backward and the chassis body 10 a is inserted between the support legs 25 below the container tank 11. Then, the elevating device is operated to raise the container tank 11 and separate the support leg 25 from the ground. Then, the arm 20 is pushed one step deeper to unlock the support leg 25 by the automatic locking device, and then the support leg 25 is rotated in the opposite direction to return to the horizontal position. Push it into the back of and store it.

Thereafter, the container tank 11 may be lowered to the original height position by the elevating device, and then mounted on the chassis main body 10 a with the tension fittings 19.

Thus, the cargo is transported by mounting the already loaded container tank 11 on the same chassis 10, and after separating the container tank 11 without waiting for the unloading operation at the destination, The loading / unloading of these container tanks is repeated so that the pistons are transported in sequence, such as immediately driving only the chassis 10 and returning to the transportation source.

When the truck is transported in this way, when returning from the destination, the unloading of the chemical solution is completed in advance, and the empty container tank 11, which stands upright on the support legs 25, is mounted on the chassis 10. You can also return.

In this case, instead of the empty container tank 11, a container tank in which another type of cargo has been loaded may be attached to the same chassis 10 and returned.

Further, in the above-described example, a configuration is adopted in which one chassis is provided with a plurality of the same container tanks 11 as a loading platform. However, according to the present invention, not only such a tank type according to the characteristics of the cargo is used. For example, it is also possible to arrange a plurality of different types of loading platforms such as a van type, a deep body type, and a flat body type, and to replace and use them as appropriate.

[0026]

Therefore, according to the invention as set forth in claim 1, the loading platform can be separated from the chassis, and when the loading platform is separated, the loading platform can be erected by supporting legs and independently supported. A truck can be constructed by arranging a plurality of loading platforms for one vehicle, and the cost of trucks when investing in equipment can be significantly reduced.

Further, by arranging a plurality of different types of loading platforms according to the characteristics of the cargo, one chassis can be used for multipurpose use, and it is not necessary to provide trucks by the number of types. The cost can be reduced accordingly.

Further, during loading the one loading platform on the chassis, during transportation, the loading platform can be loaded and unloaded in advance on another loading platform that stands upright on the support legs. In the case of transportation that takes a long time to load and unload, the load can be efficiently delivered without waiting time, and as a result, the transportation efficiency can be further improved.

[0029] The carrier separated from the chassis can be used as an independent warehouse that is optimal for loading. In addition, the next day's cargo can be loaded on the previous day, and the delivery procedure can be made more flexible.
