[Industrial applications]

 The present invention relates to a loading device having a loading guide plate for moving a loaded product onto a loading platform of a vehicle, and more particularly to a loading device for a loaded vehicle suitable for loading a vehicle or the like.

[0002]

[Prior art]

 Conventionally, when transporting vehicles and the like, they have been loaded onto freight vehicles and transported. In this case, a loading guide plate is laid between the platform of the lorry and the ground for loading. FIG. 8 is a diagram showing a vehicle loading method using a conventional loading guide plate. According to the width of the left and right wheels of the loading vehicle 41, the two loading guide plates 40 are bridged between the loading platform 42 and the ground 43, and the loading vehicle 41 is advanced through the loading guide plates 40. Place it on the loading platform 42.

Also, in recent years, as shown in FIG. 9, one end of the loading guide plate 40a is attached to the rear end of the loading platform 42a and rotated by hydraulic drive or the like so that the loading platform 42a and the ground 43 can be connected to each other. There is also a dedicated vehicle 44 for loading vehicles. This is done by lifting the front wheel side of the vehicle with a hydraulic jack 45 or the like, inclining the loading platform 42a to the rear downward, rotating the standing loading guide plate 40a to the ground 43 side by hydraulically driving it, and tilting it. The loading vehicle is loaded through the loading guide plate 40a by connecting the loading guide plate 40a with the loading platform 42a, and after loading, the loading guide plate 40a is inverted, and is erected and conveyed. According to this loading device, the loading guide plate 40a can be easily handled, and the loading space of the loading guide plate 40a is not wasted. In the case of loading a heavy vehicle such as a bulldozer, since the loading guide plate 40a is also sturdy and heavy and cannot be handled manually, the rotary loading device as described above is provided.

In addition, as shown in FIG. 10, a box-shaped loading guide plate 40b is projected rearward from a box-shaped hosing 42b provided in the lower portion of the loading platform (Actual No. Sho 59-92045). ), And as shown in FIG. 11, various ideas such as the one in which the loading platform 42c itself is moved rearward so that the loading platform rear end portion 42d is in contact with the ground 43 (Actual No. Sho 59-327). Has been done.

[Problems to be solved by the device]

 However, in the rotary loading device as shown in FIG. 9, since the loading guide plate 40a is conveyed in an upright state, it is considered that the loading guide plate 40a may fall down due to oil leakage of the hydraulic device, which is a safety problem. . For this reason, the driver's vehicle must run while constantly checking the loading guide plate 40a. Further, when carrying a load other than a vehicle, the load guide plate 40a becomes an obstacle.

In the case of the slide type loading device using the box type hosing 42b as shown in FIG. 10, the lengths of the hosing 42b and the loading guide plate 40b are limited, and the rear wheels 46 to the rear end of the loading platform. In the case of a vehicle in which the length up to the portion 42e is short, there arises a problem that the cargo bed must be remodeled for a long time. Further, there are many economical problems such as one hydraulic cylinder is required for each box-shaped hosing 42b for driving the loading guide plate 40b, and it has not been put into practical use at present.

In the case of the loading platform moving type loading device as shown in FIG. 11, since a loaded object is moved while being placed on the loading platform 42c, a strong drive device is required, resulting in high cost. In addition, it cannot be applied to a large-sized vehicle in which a plurality of vehicles are loaded.
