Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an unmanned vehicle used in an unmanned transportation system or the like.

[Conventional technology] Conventionally, this type of unmanned vehicle is shown in Fig. 6, for example.

As shown, an unmanned vehicle 2 includes a loading platform 22 on the top surface of a vehicle body 21.
3 is generally known. This unmanned vehicle 23 has been designed in advance in consideration of transportation using a forklift.

That is, a pair of hollow battery storage sections 24 extending in the vehicle width direction are provided at positions near both the front and rear sides of the vehicle body 21, and a battery 25 for power supply is removably housed in each storage section 24. When transporting the unmanned vehicle 23 to an appropriate location, remove the battery 25 from each storage section 24, insert the fork 27 of the forklift 26 into each storage section 24 as shown in FIG. 21 to be lifted and transported.

[Problems to be Solved by the Invention] However, in the conventional unmanned vehicle 23, preparations such as removing the battery 25 from the storage section 24 must be made every time it is transported, and transportation using a forklift 26 is required. The work was time-consuming.

Furthermore, when inserting the fork 27 into the storage section 24, the inserted state is hidden behind the loading platform 22, so the forklift 2
I couldn't see it from the driver's seat. For this reason, fork 27
When checking the insertion status of the driver, the operator has to get out of the driver's seat, which is troublesome.

Furthermore, since the fork 27 is inserted into or pulled out from the storage portion 24, there is a risk that the storage portion 24 may be damaged by the fork 27 at that time.

This invention was made in view of the above-mentioned circumstances, and its purpose is to simplify the work by eliminating the need for preparatory work such as removing parts such as batteries when carrying out transport work using a forklift. To provide an unmanned vehicle that can perform work accurately while confirming the work, and can further prevent injuries to the vehicle body as much as possible.

[Means for Solving the Problems] In order to achieve the above object, in the present invention, a transportation hook into which a fork of a forklift can be inserted is provided on the upper surface of the vehicle body.

[Operation] Therefore, by inserting the fork of the forklift into the transportation hook and lifting the fork, the vehicle body is lifted and the unmanned vehicle can be transported.

Further, during this transportation, there is no need to make preparations such as removing parts such as batteries from the vehicle body of the unmanned vehicle. or,
Since the transportation hook is provided on the top surface of the vehicle body, the inserted state of the fork can be seen from the driver's seat of the forklift. Furthermore, it becomes possible to limit the fork to contact with the transport hook, thereby avoiding damage to the vehicle body.

[Example] Hereinafter, an example embodying the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, the unmanned vehicle 1 of this embodiment is a transport trolley used in an unmanned transportation system, and is configured to travel controlled, that is, to be driven unmanned, along a guide line (not shown). A recess 3 is formed at the center of the upper surface of the vehicle body 2, and this recess 3 serves as a loading platform 4 on which objects to be transported are mounted.

In addition, on the front and rear sides of the loading platform 4 on the upper surface of the vehicle body 2,
A pair of transport hooks 5 are respectively provided.

As shown in FIG. 1.2, each hook 5 consists of a mouth-shaped frame 6 and a plate 7 welded to the frame 6. The plate 7 is welded to the upper surface of the vehicle body 2 and the hook 5 is is fixed to the vehicle body 2. The hooks 5 forming each moon are for inserting the fork 9 of the forklift 8 as shown in FIG. They are arranged in parallel at predetermined intervals in the vehicle width direction. That is, the forks 9 can be inserted into the hooks 5 forming each moon from both left and right sides of the vehicle body 2.

Further, in this embodiment, a band-shaped buffer member lO is attached near each hook 5 to prevent interference between the fork 9 and the vehicle body 2.

Therefore, when transporting the unmanned vehicle 1 to an appropriate location by deviating from the guide line, the forklift 8 is approached from one side of the vehicle body 2, and the fork 9 is moved in correspondence with each hook 5 as shown in FIG. Insert and lift fork 9. As a result, the vehicle body 2 is lifted up, and the unmanned vehicle 1 can be transported by the forklift 8.

The unmanned vehicle 1 of this embodiment does not require preparatory work such as removing parts such as the battery from the vehicle body 2 when transporting the vehicle, and the transport work can be carried out simply by operating the forklift 8. That is, the transportation work using the forklift 8 can be simplified.

Also, since each hook 5 is provided on the top surface of the vehicle body 2,
The inserted state of the fork 9 can be seen from the driver's seat of the forklift 8. That is, the operator of the forklift 8 can accurately transport the unmanned vehicle 1 while checking the insertion state of the fork 9.

Furthermore, when transporting the unmanned vehicle 1, the work can be carried out by simply bringing the fork 9 into contact with each hook 5, so damage to the vehicle body 2 due to contact of the fork 9 can be avoided as much as possible. Moreover, in this embodiment, since the buffer member 10 is attached to the upper surface of the vehicle body 2 near each hook 5, when the fork 9 is inserted or pulled out, the fork 9
Buffering between the vehicle body 2 and the vehicle body 2 can be prevented, and damage to the vehicle body 2 can be prevented.

Further, as described above, each hook 5 is provided for carrying out transportation work using the forklift 8, but the unmanned vehicle 1 can also be towed by hooking a rope or the like to the hook 5.

Note that this invention is not limited to the above embodiments,
In the above embodiment, each hook 5 was constructed from a mouth-shaped frame 6 and a plate 7 welded to the frame 6, but as shown in FIG. A simple configuration is also possible. or,
In addition to the square pipe 11, a round pipe may also be used.

Furthermore, as shown in FIG. 5, parts shelves 12 are provided upright on both front and rear sides of the loading platform 4 on the upper surface of the vehicle body 2, and the legs of the parts shelves 12 are formed into their own shapes to provide transportation hooks 13. You can also use it as

[Effects of the Invention] As detailed above, according to the present invention, there is no need to perform preparatory work such as removing parts such as batteries when carrying out transport work using a forklift, thereby simplifying the transport work. At the same time, the transportation work can be carried out accurately while being checked, and damage to the vehicle body can be prevented as much as possible, which is an excellent effect.
