Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a load holding device in a forklift.

BACKGROUND TECHNOLOGY Normally, Tetra Pots (registered trademark) for use in seas, rivers, etc. are installed using cranes, but from the viewpoint of workability, it is desirable to use forklifts. 2. Description of the Related Art Conventionally, a cargo holding device for a forklift has a swing frame body swingably attached to the front of a vehicle body, and a cargo holding arm that is movable up and down.

Problems to be Solved by the Invention According to the conventional cargo holding device described above, when transporting a tetrapod, the tetrapod is suspended from an arm via a wire or the like. There was a problem in that the swinging frame was damaged by contact with the body, and in some cases, the tetrapod and the vehicle body were damaged.

Therefore, an object of the present invention is to provide a load holding device for a forklift that can solve the above problems.

Means for Solving the Problems In order to solve the above problems, the load holding device for the forklift of the present invention has a load holding arm that can be raised and lowered on a swinging frame that is swingably attached to the vehicle body. A horizontal mounting frame is provided on the front surface of the arm protruding side of the lower part of the swing frame, and a first mounting bracket is provided on both sides of the horizontal mounting frame so that the position of the first mounting bracket can be adjusted in the front and back direction via a first bolt. and a second bolt is provided on each of the first mounting brackets to support the second mounting bracket so as to be tiltable in the front-rear direction via a horizontal pin, and to fix the tilting angle of the second mounting bracket so as to be adjustable; Each of the second mounting brackets is provided with a pneumatic annular elastic member for supporting cargo.

Effect: In the above configuration, when a load such as a tetrapod is suspended by an arm, the tetrapod can be brought into contact with the elastic member. Therefore, even if the tetrapod swings, the impact force is absorbed by the elastic member. Since the pressure is relaxed, it is possible to prevent damage not only to the tetrapod itself but also to the swing frame side and the vehicle body side. Furthermore, annular elastic members for supporting the cargo are provided on both sides, and the first and second mounting brackets to which the annular elastic members are attached are provided so as to be tiltable in the horizontal direction and in the front-rear direction. The support position and support direction can be optimally set according to the shape of the luggage.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the drawings.

In FIGS. 1 to 4, reference numeral 1 denotes a swinging frame body attached to the front lower part of the vehicle main body 2 so as to be swingable back and forth via a horizontal shaft 3. An elevating frame 4 that can be freely raised and lowered is arranged along a swinging frame 1. Further, inside the elevating frame 4, a guide member 6 having a load hanging arm 5 fixed to the front surface thereof is disposed so as to be movable up and down. The tip of this arm 5 projects diagonally forward, and a shackle 7 for suspending cargo is attached to the tip. Furthermore, a pneumatic rubber tire (pneumatic annular elastic member) 8 is attached to the lower front surface of the swing frame 1 on the arm 5 side so as to be movable back and forth and tiltable back and forth. That is, a horizontal mounting frame 9 is fixed to the front lower part of the swinging frame 1, and first mounting brackets 10 are mounted to the left and right positions of the horizontal mounting frame 9 with first bolts 11, and each first mounting bracket A second mounting bracket 13 is tiltably attached to the bracket 10 via a horizontal pin 12, and a rubber tire 8 is disposed on the second mounting bracket 13 in a substantially horizontal direction. Bolt holes (not shown) for fixing the first mounting bracket 10 formed in the horizontal mounting frame 9 are lengthened in the front-rear direction, and the second mounting bracket 13 has a tilting hole with respect to the first mounting bracket 10. A second bolt 14 for position fixing is provided, and the bolt hole 15 formed on the first mounting bracket 10 side is arcuate. Therefore, loosen the first bolt 11 and
By moving the mounting bracket 10, the position of the rubber tire 8 can be adjusted back and forth as shown by arrow A, and by loosening the second bolt 14, the second mounting bracket 13 is tilted relative to the first mounting bracket 10. As a result, the inclination of the rubber tire 8 in the longitudinal direction can be adjusted as shown by arrow B. In addition, in the figure, 16 is a swinging cylinder device for swinging the swinging frame 1, and 17 is a swinging cylinder device for swinging the lifting frame 4.
Cylinder device for lifting and lowering, 18
is a chain whose one end is connected to the swinging frame 4 and the other end is connected to the guide member 6 via a guide sprocket 19 at the upper end of the lifting frame 4. Therefore, when the elevating cylinder device 17 is extended, the guide member 6 moves up and down with respect to the elevating frame 4 simultaneously with the elevating and lowering of the elevating frame 4.

In the above configuration, as shown in FIG. 3 and FIG.
After connecting the tetrapod 20 via
By bringing the two rear legs 20a into contact with the rubber tire 8, it is possible to prevent the tetrapod 20 from swinging in a suspended state. There is no problem even if the vehicle main body 2 is driven in this state, and even if the tetrapod 20 swings, the impact force is absorbed and alleviated by the rubber tires 8, so it not only prevents damage to the tetrapod 20 itself, but also prevents the shaking. Damage to the moving frame 1 side and the vehicle body 2 side can also be prevented.

Effects of the Invention According to the above-mentioned configuration of the present invention, since the pneumatic elastic member is provided on the arm protruding side of the lower portion of the swinging frame, when a load such as a tetrapod is suspended by the arm, the tetrapod can not come into contact with the elastic member. Therefore, even if the tetrapod swings, the impact force is absorbed and alleviated by the elastic member, which not only prevents damage to the tetrapod itself but also prevents damage to the swinging frame and the vehicle body. It can be prevented. Furthermore, the annular elastic members supporting the cargo are provided on both sides, and the first and second mounting brackets to which the annular elastic members are attached are provided so as to be tiltable in the horizontal direction and the front-rear direction. Since the support position and support direction can be optimally set according to the shape of the load, even if the load has a complicated shape such as a tetrapod, it can be supported reliably and safely.
