Description

The present invention relates to a load collapse prevention device for a forklift that can transport a material that is easily collapsed by a forklift without being directly fixed.

Conventionally, Patent Document 1 relating to a forklift load collapse prevention device discloses a technology of a forklift load collapse prevention device that can cope with irregularities on the upper surface of a load with a simple structure.

Japanese Patent Laid-Open No. 2004-175521

According to the technique described in Patent Document 1, there is a big problem that a power source for fixing a transported object is necessary.
In addition, there is a problem that a skid (plate pallet) is required for fixing and aligning the transported object in order to stabilize the transported object.
Furthermore, since the skid (plate pallet) is used, there is a problem that the size and shape of the transported goods are restricted.

The present invention has been made in view of the above problems, and proposes a forklift load collapse prevention apparatus that does not require any power source when transporting objects that are easily collapsed by a forklift.

In order to achieve the above object, a forklift load collapse prevention device according to claim 1 is provided.
A load collapse prevention device to be mounted on a forklift provided on a vehicle body with a load receiving portion configured such that a fork extended forward is moved up and down by a mast,
A columnar removable fixed column that is attached to the base of a pair of fork claws,
A column-shaped detachable holding column that is attached to the tip of the fork claw,
It consists of a beam plate for maintaining the distance between the fixed column and the holding column,
The claw portion mounting portion of the fixed column and the holding column is formed in a box shape, and the transported item is carried without being fixed.

According to the forklift load collapse prevention device configured as described above, a power source for fixing the transported object is not required at all, and a major problem that a power source is required can be solved.

Also, by taking advantage of the advantage of not having to use skids (plate pallets) to carry the goods, the problem of having to fix the goods is solved, and the size and shape of the goods There are no restrictions.

As described above, the forklift load collapse prevention device according to the present invention has a great effect that a power source for fixing a transported object is not required at all. In addition, a fixing column and a pressing column attached to the forklift are independent of each other. Therefore, there is a convenience that adjustment of the fork is not required regardless of the size of the transported goods.

Hereinafter, examples showing embodiments of the present invention will be described with reference to FIGS. First, FIG. 1 is a block diagram showing an outline of a forklift load collapse prevention apparatus to which the present invention is applied. Reference numerals 1 and 2 denote a pair of fork claws, which are mounted on a forklift main body provided with a cargo receiving portion configured so that a fork extended forward is moved up and down by a mast.
In this embodiment, a large number of iron plates cut to a fixed size are temporarily placed on a pair of rootstocks 4 and 5.

Reference numerals 6 and 7 denote a pair of fixed columns which are attached to the bases 8 and 9 of the fork claws 1 and 2, respectively. Reference numerals 10 and 11 denote a pair of pressing columns which are attached to the tip portions 12 and 13 of the fork claws 1 and 2, respectively. Reference numerals 14 and 15 denote a pair of beam plates, which are attached to the fixed columns 6 and 7 and the holding columns 10 and 11, respectively. The beam plate 14 maintains a distance between the fixed column 6 and the holding column 10, and the beam plate 15 is It is comprised so that the space | interval of the fixed pillar 7 and the pressing pillar 11 may be hold | maintained.

FIG. 2 is a conceptual diagram showing details of the fixed column 6, which has a box-shaped mounting hole 16 for mounting to the base 8 of the fork claw 1, and does not separate from the fork claw 1 during transportation. Yes.
Further, the head has a fitting hole 17 for mounting the beam plate 14. The fixed column 7 has the same configuration.

FIG. 3 is a conceptual diagram showing details of the presser column 10, which has a box-shaped mounting hole 18 for mounting to the tip end portion 12 of the fork claw 1, and does not separate from the fork claw 1 during transportation. ing. Further, the head has a fitting hole 19 for mounting the beam plate 14.
The holding column 11 is similarly configured.

FIG. 4 is a conceptual diagram showing details of the beam plate 14, and has a dowel 20 fitted in the fitting hole 17 of the fixed column 6 and a dowel 21 fitted in the fitting hole 19 of the holding column 10 at the lower part. It is used to maintain the distance between the fixed column 6 and the holding column 10. The beam plate 15 is similarly configured.

FIG. 5 is a side view showing a state in which the temporarily placed material (iron plate) 3 is lifted by a forklift. In order to use the forklift load collapse prevention device of the present invention, first, the base portions 8 of the fork claws 1 and 2 9, the fixing pillars 6 and 7 are mounted, and after the fork claws 1 and 2 are inserted under the iron plate 3 (outside of the rootstocks 4 and 5), the holding pillars 10 and 11 are attached to the front ends 12 of the fork claws 1 and 2. 13, the beam plate 14 is mounted on the fixed column 6 and the holding column 10, and the beam plate 15 is mounted on the fixed column 7 and the holding column 11, and then the entire plate can be lifted and transported.

The fork claws 1 and 2 can be removed from the iron plate after the iron plate is carried to a predetermined place and wholesaled on a rootstock or the like, and then the beam plates 14 and 15 and the holding columns 10 and 11 are removed. Thus, the forklift load collapse prevention device of the present invention can be used with a very simple operation.
In addition, since the fixing pillar and the holding pillar are provided with box-shaped mounting holes, they can be applied to all types of existing forklifts, and the effect of high quality and mass productivity is outstanding.

As mentioned above, although embodiment of this invention was described, this invention is not limited to this, As long as the summary of this invention is not changed, it can implement in various aspects.

It is a block diagram to which the present invention is applied. It is a conceptual diagram which shows the detail of a fixed pillar. It is a conceptual diagram which shows the detail of a pressing pillar. It is a conceptual diagram which shows the detail of a beam board. It is a side view which shows the state which the conveyed product lifted.
