Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a forklift suitable for carrying hot articles such as a hot slab mass.

[0002]

2. Description of the Related Art Conventionally, as a forklift, for example, there is a standard structure having a fork 42 and a mast 43 for moving the fork 42 up and down, as shown in FIG. The fork 42 is formed in an L shape by a horizontal arm 44 and a vertical arm 45 rising from the rear end of the horizontal arm 44.

[0003]

However, when carrying a hot slab mass 46 or other high-temperature article by a conventional forklift, the hot slab mass 46 is directly forked.
As the fork 42 contacts the 42, the fork 42 becomes hot and
There was a problem that the strength of 42 decreased and it was damaged by heat.

Conventionally, when carrying a large article or when the forklift cannot access the article and must pick it up from a distance, the standard fork 42 is too short, so as shown in FIG. Sheath fork
The 47 was plugged in and used.

When the sheath fork 47 is inserted into the fork 42 in this way to support the hot slab mass 46, the hot slab mass 46 does not directly contact the lateral arm 44 of the fork 42, but is shown in FIG. So that the upper plate 47 of the sheath fork 47
Since a and the upper surface of the lateral arm 44 are in full contact,
The heat of the hot slab mass 46 is easily transferred from the upper plate 47a of the sheath fork 47 to the lateral arm 44, and when the mast 43 is tilted rearward (tilt), the hot slab mass 46 shifts backward and is forked 42. The vertical arm 45 was contacted with the vertical arm 45, and the problem that the vertical arm 45 was weakened or damaged by the heat of the hot slab mass 46 still occurred. Further, when the forklift is turned while supporting the hot slab mass 46, there is a risk that the hot slab mass 46 slips sideways and falls from the sheath fork 47.

In view of the above, the first aspect of the present invention is to provide a forklift having a fork suitable for carrying high-temperature articles at a low cost.

[0007]

In order to achieve the above-mentioned object, the invention according to claim 1 of the present invention is a forklift having a fork and a mast for moving the fork up and down. The fork is formed in an L shape by a lateral arm that supports an article and a vertical arm provided at a rear end of the lateral arm.
A heat shield sheath fork is detachably inserted, a support surface capable of supporting an article is formed on the upper surface of the heat shield sheath fork, and a heat insulating space is formed between the heat shield sheath fork and the lateral arm. Spacer, a contact prevention stopper that prevents the article supported by the support surface from contacting the vertical arm of the fork, and a skid prevention stopper that prevents the article supported by the support surface from sliding sideways in the width direction. And are provided.

According to this, when a high-temperature article is transported, a heat insulating sheath fork is inserted into the lateral arm of the fork to form a heat insulating space between the thermal insulating sheath fork and the lateral arm via a spacer. To be done. After that, when a high temperature article is supported on the supporting surface of the heat insulating sheath fork, the article does not directly contact the lateral arm, and the stopper for contact prevention regulates backward displacement, so that the vertical arm is also prevented. Do not touch. Therefore, when carrying a hot article, the hot article does not come into direct contact with the fork, and since the heat insulating sheath fork and the lateral arm form a heat insulating space, the heat of the article is It is difficult for the heat-proof sheath fork to be transmitted from the fork to the fork, which prevents the fork from reaching a high temperature. This solves the problem that the strength of the fork is reduced or damaged due to heat.

Further, the high-temperature article is prevented from sliding sideways in the width direction by the side-slip preventing stopper when supported by the supporting surface of the heat-insulating sheath fork. Therefore, when the forklift turns, it is possible to prevent hot articles from falling from the supporting surface of the heat insulating sheath fork.

Further, in the case of carrying a general article which is not at high temperature, the heat shield sheath fork may be removed from the lateral arm of the fork. In this way, by simply inserting the heat shield sheath fork into the fork of a conventional standard forklift, it is possible to handle high-temperature items sufficiently, which is very convenient, and it can be used as a dedicated vehicle only for handling high-temperature items. It is cheaper than that and can be versatile.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to FIG.
~ It demonstrates based on FIG. The forklift 1 is provided at the front of the vehicle body 2 and can be tilted back and forth (tilt is possible)
The mast 3, a finger bar 5 which is guided by the mast 3 via the lift bracket 4 and moves up and down, and a pair of left and right forks 6 provided on the finger bar 5.

The fork 6 is formed in an L shape by a horizontal arm 7 and a vertical arm 8 standing up from the rear end of the horizontal arm 7. The vertical arm 8 is attached to the finger bar 5 so as to be slidable in the left-right direction, whereby the distance between the forks 6 can be adjusted.

The lateral arm 7 has a heat insulating sheath fork 9
Is plugged in freely. The heat shield sheath fork 9 is formed in a rectangular tube shape by the upper plate 10, the left and right side plates 11, and the lower plate 12, and the tip of the heat shield sheath fork 9 is formed in a tapered shape according to the tip shape of the fork 6. ing. A supporting surface 9a capable of supporting the hot slab mass 14 (an example of a high temperature article) is formed on the upper surface of the heat insulating sheath fork 9.

Further, as shown in FIG. 3, the lateral arm 7 of the fork 6 is provided on the lower surface of the upper plate 10 of the heat insulating sheath fork 9.
A pair of left and right strip plate-shaped spacers 15 supported on the upper surface of the above are attached, and these spacers 15 form a heat insulating space 16 between the heat insulating sheath fork 9 and the lateral arm 7.

At the rear portion of the upper plate 10 of the heat insulating sheath fork 9, a contact preventing stopper 17 for preventing the hot slab mass 14 supported by the supporting surface 9a from contacting the vertical arm 8 is provided. . Further, on the outer side of the upper plate 10 of the heat insulating sheath fork 9, there is provided a skid prevention stopper 18 for preventing the hot slab mass 14 supported by the supporting surface 9a from skiding in the width direction (left and right direction). ing.

The heat insulating sheath fork 9 is inserted into the lateral arm 7 and is retained by a detachable retaining device 19. The stoppers 19 are the side plates 11 of the heat insulating sheath fork 9.
It is composed of a retaining bolt 20 which is inserted between the rear end portions and traverses the rear side of the vertical arm 8 in the left-right direction, and a nut 21 which is screwed into the retaining bolt 20. Since the retaining bolt 20 contacts the rear surface of the vertical arm 8, the heat insulating sheath fork 9 is not removed from the horizontal arm 7.

The hot slab mass 14 is placed on a carriage 23 and conveyed to a predetermined location, where the carriage is moved to a predetermined location.
Transported from 23 by forklift 1. The carriage 23 is provided with a plurality of receiving seats 24 for receiving the hot slab mass 14.

The operation of the above configuration will be described below.
When transporting the hot slab block 14, insert the heat shield sheath fork 9 into the lateral arm 7 and use both side plates of the heat shield sheath fork 9.
Insert a retaining bolt (20) between the rear ends of (11) and tighten with a nut (21). As a result, the heat shield sheath fork 9 is retained and attached to the lateral arm 7, and a heat insulating space 16 is formed between the heat shield sheath fork 9 and the horizontal arm 7.

Thereafter, the fork 6 fitted with the heat insulating sheath fork 9 is inserted between the hot slab mass 14 and the carriage 23. Then, the hot slab mass 14 is lifted from the carriage 23 by tilting the mast 3 to the rear side and raising the fork 6. At this time, since the hot slab mass 14 is supported by the supporting surface 9a of the heat insulating sheath fork 9, the hot slab mass 14 does not directly contact the lateral arm 7 and the contact preventing stopper 17 regulates the backward displacement. It also does not touch the vertical arm 8. Therefore, the hot slab mass 14 does not come into direct contact with the forks 6, and the heat insulating space 16 is formed between the heat insulating sheath fork 9 and the lateral arm 7. It becomes difficult for the sheath sheath fork 9 to be transmitted to the fork 6. Therefore, it is possible to prevent the fork 6 from reaching a high temperature,
The problem that the strength of the fork 6 is lowered or damaged due to heat is solved.

When the hot slab mass 14 is supported by the supporting surface 9a of the heat insulating sheath fork 9, the hot slab mass 14 is prevented from laterally sliding in the width direction by the lateral skid prevention stopper 18.
Therefore, when the forklift 1 turns, the hot slab mass 14 can be prevented from falling from the supporting surface 9a of the heat insulating sheath fork 9. As shown by an arrow A in FIG. 1, by sliding the vertical arm 8 in the left-right direction with respect to the finger bar 5, the distance between the forks 6 can be adjusted, so that the hot slab masses of different sizes can be adjusted. 14
Can be transported by the forklift 1.

After that, the fork 6 is lowered to lower the hot slab mass 14 to a predetermined position, and when the fork 6 is removed from the lower part of the hot slab mass 14, the heat insulating sheath fork 9 is fixed by the retaining bolt 20 and the nut 21. Since it is retained by the lateral arm 7, the heat insulation sheath fork 9 is also reliably removed from the lower part of the hot slab mass 14 integrally with the fork 6.

When carrying general articles that are not at high temperature, as shown by the phantom lines in FIG. 4, the retaining bolt 20 and the nut 21 are removed from the heat insulating sheath fork 9, and the lateral arm 7 of the fork 6 is removed. The heat shield sheath fork 9 may be removed from the cover.

In this way, by simply inserting the heat insulating sheath fork 9 into the fork 6 of the conventional standard forklift 1 and retaining it with the retaining bolt 20 and the nut 21,
Since it can sufficiently cope with high-temperature articles such as the hot slab mass 14, it is very convenient, is cheaper than a dedicated vehicle only for handling high-temperature articles, and is versatile.

In the above embodiment, the heat insulating space
A heat insulating material may be inserted into 16 to enhance the heat insulating effect between the heat insulating sheath fork 9 and the lateral arm 7. Moreover, a fin for heat dissipation may be provided on the surface of the heat shield sheath fork 9 to effectively dissipate the heat of the heat shield sheath fork 9.

[0025]

As described above, according to the invention described in claim 1 of the present invention, when carrying a high temperature article,
Since the high temperature article does not directly contact the fork, and because a heat insulating space is formed between the heat insulating sheath fork and the lateral arm, it becomes difficult for the heat of the article to be transmitted from the heat insulating sheath fork to the fork. Therefore, it is possible to prevent the fork from reaching a high temperature, and the problem that the strength of the fork is reduced or damaged due to heat is solved.

Further, since the high temperature article is prevented from laterally slipping in the width direction by the side slip prevention stopper when supported by the supporting surface of the heat insulating sheath fork, the high temperature article is rotated when the forklift turns. Can be prevented from falling from the supporting surface of the heat insulating sheath fork.

When a general article that is not hot is to be carried, the heat shield sheath fork may be removed from the lateral arm of the fork. In this way, by simply inserting the heat shield sheath fork into the fork of a conventional standard forklift, it is possible to handle high-temperature items sufficiently, which is very convenient, and it can be used as a dedicated vehicle only for handling high-temperature items. It is cheaper than that and can be versatile.
