Description

[Detailed Description of the Invention] The present invention relates to a pad for preventing cargo from collapsing in a forklift for transporting annular articles such as wheels, flanges, gear materials, etc.

For example, several wheels are stacked vertically using a forklift, or several wheels are stacked horizontally, and the axle portion is skewered using a fork for transportation. However, conventional stacking of plates tends to cause the load to collapse, so pads are placed around the wheels of stacked plates to prevent the load from collapsing. In the case of a skewer, the part was removed, and in the case of stacking plates, the part was attached. Therefore, the operator has to get off the vehicle and attach/detach each time, which is a cumbersome task.

The present invention solves all of the above-mentioned conventional problems at once, by placing a part on the front of the fork mounting plate, and when using a skewer, the part is brought out to the front so that it does not get in the way of the skewer. In the case of stacking plates, the part is moved back to the fork mounting plate and is not used as the original part to prevent the load from collapsing.

The present invention will be described below with reference to an embodiment shown in the drawings. Reference numeral 1 denotes a forklift truck, and a fork mounting plate 2 is provided on the front side of the truck. Reference numerals 3 and 3 denote L-shaped forks, and L-shaped engagement pieces 4 and 4' are attached to the rear upper part, and guide bodies 5 and 5' are attached to the rear lower part, and these are attached to the fork mounting plate. 2, and engages with an engagement receiver 6 provided on the upper part of the fork mounting plate and a guide receiver 7 provided on the lower part of the fork mounting plate, respectively. When a fork drive device (not shown) is operated, the forks 3, 3 can be moved toward or away from each other in the left-right direction while maintaining engagement with the fork mounting plate 2.

On the other hand, a support post 8 is provided upright on the upper part of the fork mounting plate 2. Reference numeral 9 denotes a part for preventing cargo from collapsing, which is arranged on the front side of the fork mounting plate 2. Links 10 and 11 are installed to straddle this part 9 and the support post 8, and both ends of the parts are pivotally connected. The mechanism is configured. Furthermore, the links 10 and 11 are arranged so that the post-side pivot point of one link is always located above the pad-side pivot point. Further, as shown in FIG. 4, the forks 3, 3 have a cam 12 having an inclined surface 12a

In the device configured as described above, when the plates are stacked and transported, as shown in FIGS.
retreating to the side. In this state, the flange portion 13a of the lowermost wheel of the wheels 13, 13, . At that time, wheels 13,1
3... hits part 9 and prevents the load from collapsing.

In the case of skewering, when the forks 3, 3 are brought close together, the inclined surface 12a of the cam 12 hits the side of the part 9. If the part 9 is brought closer still, the side portion of the part 9 will protrude forward while slidingly contacting the inclined surface 12a. Therefore, even if the forks 3 and 3 are brought close together, the parts 9 will not get in the way. Thus fork 3,

Pass through the axle part of 3, 13... and transport it in a lifted state.

As mentioned above, in this invention, the parts are always attached to the forklift, and the parts, posts, and links constitute a parallel crank mechanism, so when inserting a skewer, it can be moved forward so as not to get in the way. This is effective in improving work efficiency, since it is not necessary to get off the forklift and attach/detach the parts at each shift of transportation work, as is the case in the past. In addition, if the part is automatically released via the cam as the fork approaches, as in the above embodiment, there is an effect that the operations are linked and reliable.

Claims (1)

[Scope of Claim for Utility Model Registration] L-shaped forks are provided on the front of the fork mounting plate so as to be movable in the left and right direction, and the shafts of annular products arranged in the front and back direction are interdigitated with the forks brought close to each other. In a forklift that holds and transports circular articles stacked vertically in an expanded state, a part for preventing the load from collapsing is arranged on the front of the fork mounting plate, and a part is placed on the top of the fork mounting plate. A parallel crank mechanism is constituted by an upright post, the part, and a link extending over these parts, and the part is always in an upright position and is freely movable back and forth, and the part is moved backward by its own weight when the fork is extended. ni, 1
The links are arranged so that the pivot points on the post side of the two links are always located above the pivot points on the part side, and the parts are attached to the forks so that the parts protrude forward when the forks are brought close together. A part for preventing a load from collapsing in a forklift, characterized by being provided with a cam that can push the part forward by coming into contact with a side part of the part.
