Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for transporting cargo such as containers by a cargo handling vehicle that utilizes a cargo handling vehicle having a cargo handling arm that can be raised and lowered and a towed vehicle.

(Prior art) A cargo handling vehicle is known in which a cargo handling arm is provided on the vehicle body frame so that it can be raised and lowered, and cargo such as containers is loaded and unloaded between the vehicle body frame and the ground by the raising and lowering of the cargo handling arm (for example,
49−45806).

(Problems to be Solved by the Invention) The cargo handling vehicle has a loading/unloading function, but due to its mechanism, it can only handle a single large cargo.

(Means for Solving the Problem) The present invention provides a cargo handling arm that can be raised and lowered on a vehicle body frame,
The cargo handling arm is connected to cargo such as a container and can be lifted up and down to load and unload between the vehicle body frame and the ground.A towed vehicle can be connected to the cargo handling vehicle via a coupling device, and the cargo handling arm After loading the cargo onto the cargo handling vehicle, the cargo handling arm connects the towed vehicle and transfers the cargo to the towed vehicle, then once the towed vehicle is disconnected, the cargo handling arm loads the cargo onto the cargo handling vehicle again. By connecting the cargo handling vehicle and the towed vehicle, it is possible to transport a plurality of loads.

(Embodiment) Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
It is pivoted 3 so that it can be raised and rotated back and forth.

The cargo handling arm 2 consists of a base arm 4 and an L-shaped tip arm 5 that is telescopically inserted into the base arm 4. A telescopic cylinder 6 is connected between the base arm 4 and the leading arm 5. 6, the tip arm 5 becomes the base arm 4.
It can be expanded or contracted.

A lift cylinder 7 is connected between the vehicle body frame 1 and the base arm 4, and by the expansion and contraction operation of the lift cylinder 7, the cargo handling arm 2 can be raised and rotated back and forth around the pivot 3.

A hook 8 is fixed to the tip of the front arm 5 of the cargo handling arm 2, and the hook 8 can be engaged with and detached from a locking piece 9 of a container C, which is cargo.

Container C is placed at the upper rear end of body frame 1 of cargo handling vehicle V.
A pair of guide rollers 10 that support and guide the lower surface are rotatably supported, and a connector 11 is fixed to the center of the rear end, and a full trailer as a towed vehicle is connected to the connector via a drawbar 12. T is connected (the coupling tool 11 and the drawbar 12 constitute a coupling device). The full trailer T has a loading platform 14 on the upper surface of the frame 13, which is approximately at the same height as the upper surface of the vehicle body frame 1, and an appropriate number of locking means 15 for the container C are disposed so as to be freely retractable. In addition, 16 is a frame 13 with jack.
Appropriate number of them will be placed.

Next, to explain the operation of the present invention, loading and unloading is performed according to the following procedure.

(1) As shown in Figure 2, the cargo handling vehicle V approaches the waiting container C.

(2) After contracting the telescopic cylinder 6 and retracting the front arm 5, the cargo handling arm 2 is raised rearward, and the hook 8 is engaged with the locking piece 9 of the container C. Next, the cargo handling arm 2 is laid forward and loaded onto the vehicle body frame 1 (FIG. 3).

(3) When loading of container C is completed (Fig. 4),
The cargo handling vehicle V is brought close to the parking place of the full trailer T and stopped.

After that, the telescopic cylinder 6 is contracted and the tip arm 5 is
and move the container C backward and place the rear end of the container C on the loading platform 14 of the full trailer T (fifth
figure).

(4) Extend the lift cylinder 7, raise the cargo handling arm 2 rearward, and unload the container C onto the loading platform 14 of the full trailer T (Fig. 6).

(5) Unload the container C onto the full trailer T, actuate the locking means 15, and after it is completely loaded, lay down the cargo handling arm 2 and return it to the vehicle body frame 1 (Fig. 7), and the cargo handling vehicle V Leave the full trailer T (Figure 8).

(6) When the cargo handling vehicle V reaches the waiting area of another container C', the cargo handling arm 2 is raised rearward again, the hook 8 is engaged with the locking piece 9 of the container C', and then the vehicle body frame 1 is (Figure 9).

(7) When the container C' is completely loaded onto the vehicle body frame 1, the cargo handling vehicle V approaches the parking place of the full trailer T again, connects the two with the drawbar 12 and the coupling device 11, and then drives to the destination. Transport by running (Figure 10).

Moreover, when unloading a container, the above procedure can be reversed.

In (5) and (6) above, only the cargo handling vehicle V was run, but when the distance between the full trailer T and the container C' is large, the full trailer T is moved once to the cargo handling vehicle V.
It is also possible to connect it to the container C' and tow it to the location of container C'. Furthermore, if the full trailer T can be made longer, two or more containers may be loaded thereon.

(Effects of the Invention) As described above, the present invention significantly improves transportation efficiency by loading and unloading cargo such as containers not only between a cargo handling vehicle and the ground, but also between a full trailer. .

Claims (1)

[Claims] 1. A coupling device is installed on a cargo handling vehicle in which a cargo handling arm is provided on the vehicle body frame so that it can be raised and lowered, and the cargo handling arm is connected to cargo such as a container so that it can be loaded and unloaded between the vehicle body frame and the ground by raising and lowering the cargo handling arm. After loading cargo onto the cargo handling vehicle using the cargo handling arm, the towed vehicle is coupled and the cargo is transferred to the towed vehicle using the cargo handling arm, and once the towed vehicle is separated, the cargo is transferred to the towed vehicle. A transportation method using a cargo handling vehicle, in which a plurality of cargoes can be transported by loading the cargo onto the cargo handling vehicle again using the cargo handling arm and connecting the cargo handling vehicle and a towed vehicle.
