Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a truck bed moving apparatus for horizontally moving a truck bed, unloading it to the ground, loading and unloading it, and then mounting it on a chassis.

[0002]

2. Description of the Related Art Generally, a farmer uses agricultural equipment, fertilizer, straw,
Small so-called light trucks are used for transporting agricultural products and the like, and for delivering products to small-scale shops.
In such a truck, the loading platform is fixed on the chassis, and the loading and unloading of the loading is done manually, so it takes a lot of work to lift the load from the ground to the loading platform or lift it from the loading platform to the ground. Is required.

Although labor is reduced if a cargo handling machine such as a crane or a forklift is used for unloading cargo, a cargo handling machine is used for unloading a relatively small load on a small truck having a small load capacity. It is troublesome and inefficient to prepare and use.

[0004]

SUMMARY OF THE INVENTION The present invention is to solve such a problem in the loading and unloading work of a small truck, and when loading and unloading a load, the bed of the truck is horizontally moved and unloaded to the ground to load and unload the load. It is an object of the present invention to provide a truck bed moving device capable of reducing the labor and improving the work efficiency by mounting it on the chassis after carrying out.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a guide rail is laid on a chassis frame of a truck in the front-rear direction, a feed chain is stretched in parallel with the guide rail, and a lifter for supporting and lifting the front end of a cargo bed is lifted. The above problem is solved by constructing a truck bed moving device by mounting the carriage so that it can move forward and backward along the guide rail and connecting it to the feed chain, and providing an outrigger at the rear end of the truck. ing.

[0006]

In loading and unloading work, after fixing the outrigger to the ground, the lifter is moved backward by the feed chain to the rear end of the guide rail, and the load platform is lowered by the lifter to the ground. When the loading platform is placed on the ground, the operator can easily load and unload the loading. When the loading and unloading is finished, the loader is lifted to the position of the guide rail with the lifter, and the lifter is advanced to the front end of the guide rail with the feed chain to mount the loader on the chassis frame. After that, the outrigger is stored and the truck is driven.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view showing the construction of a truck bed moving device according to an embodiment of the present invention, FIG. 2 is an explanatory view of the arrangement of guide rollers, and FIG. FIG. 4 is a perspective view showing a state where the luggage carrier is mounted on the chassis frame. In this embodiment, the truck 1 is provided with a cab 2 in the front part of the chassis frame 3, and guide rails 8 are laid along the left and right sides on the upper surface of the chassis frame 3 behind the cab 2.

On the side faces of the front and rear ends of the guide rail 8,
Sprockets 30 and 31 are axially mounted, and an endless feed chain 32 is wound around the sprockets 30 and 31 and stretched in parallel with the guide rail 8. A geared motor 33 is installed above the front end of the guide rail 8, and a drive sprocket 34 for the geared motor 33 is installed.
From a drive chain 36 to transmit rotation to a driven sprocket 35 mounted coaxially with the sprocket 30.

A lifter 4 is mounted on the guide rail 8 so as to be able to move forward and backward, and the lifter 4 is connected to a connecting bracket 37.
And is connected to the feed chain 32. The lifter 4 comprises a pedestal 10 having guide wheels 9 that are guided by guide rails 8 to roll, and a guide frame 11 for supporting the front end of a loading platform 5 of a truck 1 and moving the guide frame 11 upright. An electric winch 38 is provided on the upper end of the guide frame 11.
Is installed, and one end of the wire 39 of the electric winch 38 is attached to the luggage carrier 5. The loading platform 5 is provided with a supporting frame 14 provided with a guide roller 13 at the front end thereof in a standing manner.
This guide roller 13 is a guide frame 11 of the lifter 4.
Guided by and rolls up and down by raising and lowering the electric winch 38. Further, the loading platform 5 is provided with guide wheels 15 on its lower surface, which are guided by the guide rails 8 to roll.

Gard motor 33 and electric winch 38
Is driven by the on-vehicle battery 18 of the truck 1. A manually attached and detachable outrigger 7 is attached to the rear end of the guide rail 8.
Is provided. In this embodiment, since the truck 1 is small, a manual type outrigger is used, but a hydraulic type outrigger may be provided if necessary.

In loading and unloading work, after mounting the outrigger 7 from the state shown in FIG. 4 and fixing it on the ground, the gear motor 33 is driven to move the lifter 4 backward by the feed chain 32 to the rear end of the guide rail 8. . Next, electric winch 3
8 is lowered and the loading platform 5 is lowered along the guide frame 11 to the ground. When the loading platform 5 is placed on the ground as shown in FIG. 1, the worker can easily load and unload loads manually.

When the loading and unloading is finished, the electric winch 38
Is wound up, and the loading platform 5 is raised to the position of the guide rail 8 along the guide frame 11. Then, the geared motor 33 is driven to move the lifter 4 forward by the feed chain 32 to the front end of the guide rail 8. The carrier 5 is the lifter 4
Along with it, it advances along the guide rails 8 and is mounted on the chassis frame 3. Thereafter, as shown in FIG. 4, the outrigger 7 is removed and stored, and the truck 1 is run.

FIG. 5 is a perspective view showing the construction of a truck bed moving device according to another embodiment of the present invention. In this embodiment, as a drive means for the feed chain 32, a drive frame 40 is installed above the front end of the guide rail 8 instead of the geared motor 33. Drive frame 40
Is the drive hydraulic cylinder 41 and the drive hydraulic cylinder 41
A drive sub-frame 42 that moves up and down along the drive frame 40 by expansion and contraction of the drive frame 40 is provided, and a drive sprocket 43 axially attached to the upper end of the drive frame 40 and a driven sprocket 35 coaxially attached to the sprocket 30 are provided. A drive chain 36 is hung around the drive chain 36, and a drive subframe 42 is connected to the drive chain 36 by a connection bracket 44. Therefore, the expansion and contraction of the drive hydraulic cylinder 41 transmits the rotation to the driven sprocket 35. By setting the driven sprocket 35 to have a smaller diameter than the sprocket 30, the feed chain 32 can be moved largely as compared with the expansion and contraction stroke of the drive hydraulic cylinder 41.

Further, in place of the electric winch 38, the guide frame 11 is provided with an elevating hydraulic cylinder 46 having an elevating sprocket 45 at the upper end, and one end of which is lifter 4.
The lifting chain 47 attached to the pedestal 10 is folded around the lifting sprocket 45, and the other end is attached to the loading platform 5. Therefore, the lifting distance of the loading platform 5 is double the stroke of expansion and contraction of the lifting hydraulic cylinder 46.

In this embodiment, a drive hydraulic cylinder 41 for moving the lifter 4 back and forth and a hydraulic cylinder 4 for raising and lowering the platform 5.
A hydraulic power unit 19 driven by a vehicle-mounted battery 18 is provided as a hydraulic power source of No. 6. During the unloading work, the loading platform 5 can be moved as in the case of the embodiment shown in FIG.

[0016]

As described above, in the loading platform moving apparatus of the present invention, the loading platform of the truck is horizontally moved and unloaded to the ground at the time of loading and unloading, and then the loading platform is mounted on the chassis. As a result, the labor of the worker can be reduced and the work efficiency can be improved.
