Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a cargo handling vehicle such as a pallet loader used for carrying cargo into and out of a truck.

[Prior art] For example, when unloading cargo from a truck loaded with air cargo onto a dolly (a trolley towed exclusively for the airport) at an airport, the cargo previously placed on a pallet is moved by a forklift. In some cases, the entire pallet is transported.

[Problems to be Solved by the Invention] However, when loading and unloading cargo using a forklift in this manner, there is a risk that the cargo may become loose depending on the cargo being loaded, and it is difficult to prevent this. Furthermore, since forklifts usually load cargo in front of the driver's seat, there is a problem in that the visibility from the driver's seat is poor and driving is highly dangerous.

[Means for Solving the Problems] The present invention has been made to solve the above problems, and includes a traveling trolley, a cargo loading platform provided on the traveling trolley so as to be movable up and down, a driver's seat for driving a traveling trolley, and a cargo loading position adjustment mechanism is provided on the top surface of the platform to transfer the loaded tribute to approximately the center of the platform and fix the cargo at that position, The feature is that the driver's seat for driving the traveling bogie is provided on the side of the traveling bogie.

[Operation] The cargo sent onto the platform is transferred to approximately the center of the Blatt Bohm by the cargo loading position adjustment mechanism and fixed at that position, so that it is stably loaded on the platform.

In addition, the driver's seat is located on the side of the traveling truck, and its visibility is not affected by the cargo loaded on the Blattbohm installed on the traveling truck, so you can drive safely.

[Embodiment] Hereinafter, a pallet loader (cargo handling vehicle) according to an embodiment of the present invention will be described with reference to FIGS. 1 to 5.

1 to 3 show an overall plan view, side view, and front view of this pallet loader, respectively.

In these figures, reference numeral I indicates a traveling truck equipped with wheels 2, and numeral 3 denotes a cargo loading platform provided on the truck I.

A driver's seat 4 for driving the truck is provided on the right side of the truck 1 in the forward direction (to the right in FIGS. 1 and 2), and a box 5 behind the driver's seat 4 is provided to drive the truck 1. It is equipped with an engine 6.

The wheels 2 are made of hard rubber that hardly deforms even when loaded with heavy cargo.

As shown in FIGS. 2 and 3, the Blattbohm 3 is attached to the trolleys 1 and h via scissor links 8 that are bent and extended by a hydraulic cylinder 7, and can be raised and lowered. Guides 9 are provided at both ends of the platform 3 to prevent the pallet from falling.

As shown in FIG. 1, hard balls 10 are rotatably embedded in the edge of the upper surface of the platform 3 at appropriate intervals. Since this ball 10 is rotatable in all directions, it serves as a roller for transporting loaded pallets on the platform 3.

Further, rollers 11 are rotatably provided at the front and rear ends of the Blatt Baum 3, and furthermore, on the platform 3 side of these rollers 11, there are drive rollers 12 for feeding and feeding the pallet onto the Plan/Bohm 3. is provided.

In addition, on the upper surface of the platform 3, as shown in FIG. 1, two rows of transport tires 13 are arranged on the left and right (one row consists of three tires) for transporting pallets onto the platform 3. Further, a pair of lateral moving tires I4 for moving the pallet in the lateral direction of the Blatt Baum 3 are arranged at the rear of the pallet.

On the left and right sides of the lateral movement tires 14, plate-shaped stoppers 15 are provided at positions equidistant from the front and rear ends of the platform 3 to stop the pallet from moving back and forth. These stoppers 15 are made into a pair on the front side and a pair on the rear side, and as shown in FIG. 4, by operating one cylinder 16, the stopper I5 is rotated in conjunction with the link I7. However, it was made so that it could jump out on top of Blattbohm 3 or connect with it.

It should be noted that the distance between the stoppers I5 after the surface substantially matches the length of the normally used pallet.

Furthermore, at the left end of the platform 3, on the front and rear end sides of the platform 3 relative to the stopper 15, pallet locks are provided for pressing the pallet against the guide 9 at the right end and fixing the pallet on the platform 3. A mechanism 18 is provided. This lock machine +1■I8 is,
As shown in Fig. 5, f is fixed on the platform 3 side.
As for the temporary guide I9, the lock plate 20, which has an angular cross-section and whose tip protrudes from the upper surface of the platform 3, is moved in the width direction of the platform 3, so that the I hyperactivity is caused by the cylinder. 21 (Thus, this locking mechanism ■8 lock plate 20
The tip is usually located outside the end of the platform 3.

In addition, this locking machine fM I 8 is Bratbohm 3
This board is used when fixing a pallet on the platform 3, which has a length approximately equal to the entire length of the pallet.

The above-described transport tire I3, lateral +3 tire 1-1, stopper 15, and lock mechanism 18 constitute an adjustment mechanism that places the pallet approximately at the center of the pla-sotopome 3 and fixes it at that position.

Next, an explanation will be given of the operating procedure when such a pallet loader is used to, for example, load and unload a pallet loaded with cargo on a truck bed.

First, the rear of the pallet loader is brought close to the truck bed, and the hydraulic cylinder 7 is activated to raise the platform 3 to the truck bed.

Next, raise the front stopper 15 and raise the rear stopper 1.
5 is lowered, the drive roller 12 and transport tires 13 are rotated, and the pallet is transported onto the platform 3 until it hits the stopper 15 on the front side.

After that, the rear stopper 15 is raised to prevent the pallet from shifting in the front-back direction. If the pallet is shifted to either the left or right on the platform 3 at this point, the lateral moving tires 14 are rotated to move the pallet laterally to the center.

As a result, the center of gravity of the pallet is fixed at the center position 12 on the platform 3 in this state.

Then, lower platform 3 and drive to the desired location, for example, the location where Dori is waiting.
Transfer the pallet onto the dori.

Next, a case will be described in which a pallet having a length longer than the length between the front and rear stoppers 15 and approximately the same as the length of the platform 3 is loaded and fixed on the platform 3.

In this case, the pallet is transported by the transport tires 13 so that its longitudinal center of gravity is at the center of the platform 3, and then the locking mechanism 18 is
0 is actuated to move inward, and this lock plate 20 forces the pallet against the guide 9 on the right side. This leaves the pallet fixed on the platform 3.

As described above, according to the pallet loader of this embodiment, by using the transport tires 13 and the lateral movement tires 14, the pallet to be loaded can be easily placed in the center on the platform 3, and further, Stopper 15
Alternatively, the locking mechanism 18 could be used to fix it in that position. Therefore, it has become possible to transport cargo in a stable state without the pallet shifting.

Further, the driver's seat 4 of this pallet loader is located on the front right side of the truck 1, so that the driver's field of view is not affected by the cargo on the pallet to be loaded. Therefore, the vehicle can be operated safely even when loaded with cargo.

Furthermore, the wheels on the trolley l are loaded with Shigenobu cargo.
Since it is made of hard rubber that hardly deforms even when the weight is lifted, there is no need to provide a stabilizer on the cart side to support the weight.

[Effects of the Invention] As explained above, according to the cargo handling vehicle of the present invention,
There is a cargo loading position adjustment mechanism on the top of the cargo loading platform that moves the cargo to the approximate center of the platform and fixes the cargo in that position, so it is easy to move the cargo to the center of the platform. Furthermore, it is possible to secure the cargo in the first place. Therefore, it has become possible to transport the cargo in a stable state without shifting the cargo. Further, since the driver's seat is provided on the side of the traveling truck, the vehicle can drive safely without having its visibility affected by the cargo loaded onto the platform provided on the traveling truck.
