Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a forklift cargo handling device which is excellent in handling long loads.

[0002]

2. Description of the Related Art Generally, a forklift is provided with a pair of left and right forks, and the forks are mainly inserted into the front of the pallet to carry the pallet.
In some cases, the load g may be directly placed on the forks f, f to be transported, as shown in FIG.

[0003] Above all, when the load to be conveyed is, for example, a bundle of log members h having a long shape, the fork width W of the forks f, f is raised and lowered by the lifting tool c for moving the mast b up and down.
The load g is expanded along the finger bar d to maximize the stability of the load g in the left-right direction, and the forks f, f are tilted rearward to maintain the stability in the front-rear direction.

[0004]

However, in the above-mentioned prior art, when the length L of the load g is larger than the fork width W (for example, L / W is twice or more). Is
There is a risk that the load g during transportation is not stable and may fall from the fork f.

The present invention has been devised in view of the above problems, and is based on the provision of a link-shaped load holder having a plurality of arms protruding outward from the fork base body in the vehicle width direction. It is an object of the present invention to provide a cargo handling device for a forklift that can solve the above problems.

[0006]

DISCLOSURE OF THE INVENTION The present invention is directed to a fork base body which is arranged on an elevator for raising and lowering a mast of a forklift and extends to the front of the vehicle body. A cargo handling device for a forklift, comprising a link-shaped load holder having a plurality of arms protruding outward in the vehicle width direction.

[0007]

By making the link-shaped load holder project outward from the fork base body in the width direction of the vehicle body, the width dimension for holding the load together with the fork base body is increased, and stable load support is possible.

Further, the fork base body is composed of a fork of a forklift and a sheath-like body which is detachably mounted on the fork, and a load holder is provided on the sheath-like body, so that a long load can be loaded. It is easy to handle and can also be handled by a normal fork.

Further, by fixing the load holder in a state along the fork base body and in a state of protruding outward,
This is preferable in that the load holder can hold the load without inadvertently changing the position due to vibration, centrifugal force, or the like generated while the forklift is traveling.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The cargo handling device 1 of the present invention is composed of a fork base 2 which is arranged on an elevator for raising and lowering a mast of a forklift and extends to the front of the vehicle body, and a load holder 3 which can project outward from the fork base 2 in the vehicle width direction. .

In the present example, the fork base body 2 is a fork 6 which is engaged with, for example, a finger bar of a lift bracket for moving up and down the mast of the forklift, and this fork 6.
And a long sheath-like body 7 having a hollow portion 7A that can be detachably attached to the shell-like body 7, and both are integrally fixed by screwing a bolt B from a hole portion 7B formed in the sheath-like body 7. To be done.

In this example, the load holder 3 has two slidable arms 4A and 4B pivotally supported by brackets 10 and 11 fixed to the side wall of the sheath 7 and the arms 4A and 4A.
4B and a link body 5 rotatably supported by pins P1 and P2 to form a substantially parallel link mechanism, and the arms 4A and 4B are swung to move the link body 5 to the fork base 2 Can project outward from the width of the vehicle,
The width dimension for supporting the load by the arms 4A, 4B and the link body 5 is increased.

Further, in this example, the arms 4A and 4B are fixed by the fixing means 9 fixed at a position along the fork base body 3 (shown by a solid line in FIG. 1) and in a state of protruding outward (shown by a chain line). Equipped with.

The fixing means 9 is, in this example, the arm 4A.
In addition, the overhanging portion 12 extending beyond the pin P1 and the first locking hole H1 are formed in the overhanging portion 12, and the link body 5 is placed so that the link body 5 is closest to the fork base body 2. Projection 13 that substantially overlaps the overhanging portion 12 at the open position
The second locking hole H2 that communicates with the first locking hole H1 is provided at the same time, while the arms 4A and 4B are moved from this position by approximately 90 °.
A third portion that communicates with the first locking hole H1 in a swinging state.
Locking holes H3 and the first, second, and third locking holes H
1, H2, and H3, and a fixing pin 14 that can be inserted therethrough.

Therefore, in order to fix the arms 4A, 4B and the link body 5 along the fork base body 2, the fixing pin 1
4 is inserted into the first and second locking holes H1 and H2, while the arms 4A and 4B and the link body 5 are fixed in a state of protruding outward, the fixing pin 14 is fixed to the first and third positions. Locking hole H
1. Insert in H3.

By providing the fixing means 9 for fixing the load holder 3 at any one of the positions as described above, rattling of the load holder 3 and the position thereof are changed by vibration, centrifugal force and the like during traveling of the forklift. This helps prevent the load from falling.

Further, in this example, the height dimension K1 of the sheath 7 is
Is smaller than the height of the insertion port of the wooden flat pallet, and the thickness K2 of the load holder 3 is smaller than the height K1 and is located within the height K1. The load holder 3 is arranged so that it can be inserted into an ordinary wooden flat pallet while being placed along the fork base body 2. In such a case, it functions as a so-called sheath fork, which simply increases the fork length.

FIG. 2 shows another embodiment. As shown in the figure, the load holders 3 are provided on the left and right side walls of the fork base body 3, and according to this configuration, two long loads g1,
This is preferable in that g2 can be juxtaposed to perform cargo handling.

Further, FIG. 3 shows another embodiment of the fixing means. This one has an arc-shaped projecting piece 15 formed around the pin P1 in the link body 5 and, in this example, has five locking holes H4 at an equal angular pitch centered around the pin P1. The thing is illustrated. According to such a configuration, the load holder 3 can be adjusted to a width dimension suitable for the long dimension of the load, and the passage width required for traveling can be suppressed to the minimum, which is preferable.

As described above in detail, the cargo handling device of the forklift according to the present invention is modified into various modes such as directly mounting the load holder on the fork of the forklift and improving the strength by providing three or more arms. sell.

[0021]

As described above, the cargo handling device for a forklift according to the present invention is excellent in handling a load of a long object, and can also handle a load of a normal fork. Further, the position of the load holder can be fixed to improve workability and perform safe work.
