BACKGROUND OF THE INVENTION
The present invention relates to a carrying device for collecting materials that hangs a load of wood or the like and travels on a rope.
[0002]
[Prior art]
In logging work in forestry, a cable with a wire cable is installed between the main column and the front column, and a carrier is attached to the rope so that it can run freely. Wood is suspended from the carrier, and the carrier is mounted by a winch that is a collector. By pulling or pulling back, the wood is transported and collected.
[0003]
With reference to FIG.4 and FIG.5, the typical example of the carrying device and the timber conveyance method using the same is demonstrated. A transporter 40 is movably attached to a pullback line 38 extending between the guide pulleys 36 and 37 of the main pillar 32 and the front pillar 34 from the pullback winch 30a of the gathering machine 30. The carrier 40 includes a pair of upper and lower pulleys 40b and 40c on a main body 40a. The upper pulley 40b is movably hung on a pull-back line 38, and the main body 40a is folded back through a pulley 37 of a leading post 34. An end 39 of the retracting line 38 is connected. A pulling rope 44 extending from the pulling winch 30b of the gathering machine 30 is passed through the lower pulley 40c through a guide pulley 42 attached to the main column 32, and a loading hook 46 is attached to the tip of the pulling rope 44c. .
[0004]
In order to transport the timber 48 to the gathering place 50 provided on the side of the main pillar 32, the winch driver first winds up the empty loader 40 and the loading hook 46 to the position of the carrier 40, and then pulls back the rope 38. And tension the drawline 44 and lift it into the air. Then, the retracting line 38 and the pulling line 44 are wound or unwound and sent to the vicinity of the wood 48 that conveys the transporter 40. When the transporter 40 reaches the target position, these cables are loosened and the transporter 40 is lowered to the ground. The sled worker near the lowered transporter 40 gives instructions to the winch driver to prompt the delivery line 44 to be sent out, and pulls out the pulling line 44 from the transporter 40, as indicated by K1 in FIG. The wire 46 of the drawing line 44 is dragged 46 to the wood 48 to be conveyed, and the loading hook 46 is hung on the wood 48.
[0005]
When the loading hook 46 is finished hanging on the wood 48, the winch driver operates the pullback winch 30a and the pulling winch 30b to tension each of them, and lifts the wood 48 (state K2 in FIG. 4). Then, the retracting line 44 is wound up, the retracting line 38 is fed out, and the transporter 40 with the timber 48 suspended is run on the retracting line 38, and the timber 48 is conveyed to the collecting place 50.
[0006]
[Problems to be solved by the invention]
However, the conventional carrying device for collecting materials as described above has the following problems to be solved.
[0007]
(1) Wire to wood:
When the loading hook 46 of the pulling line 44 is hung on the wood 48 to be conveyed, the wire is pulled to the position of the wood 48 while pulling the wire of the pulling line 44 from the transporter 40 that has descended to the ground. Since the drag resistance of the wire and the wire itself are greatly affected, a large amount of labor is required for the handling of the wire.
[0008]
(2) Carryer structure and mounting form:
In order to facilitate the handling of the wire, there is a case in which a winch is provided in the inside of the carrying device 40, but this is expensive, and the size and weight of the carrying device are also increased. As shown by a two-dot chain line in FIG. 4, a pulling cable 52 is connected to the carrier 40 and a guide pulley 54 is added to the base column 32 and pulled by a winch, and the carrier is positioned in the air without being lowered to the ground. Additional equipment and expenses are required, such as the installation of new collectors and construction work.
[0009]
(3) Carrying the carrier:
Carryers for hanging wood are strong and heavy. Therefore, a large amount of labor is required for transporting the transporter in an irregular gathering place when the gathering place is moved. In addition, it is necessary to move the transporter when handling the wire, such as hanging a wire on wood, and it is desired to reduce the weight of the transporter. As described above, when a winch is provided in a transporter, the weight becomes heavier and the transporter becomes more difficult to transport.
[0010]
The present invention has been made in view of the above-mentioned facts, and its technical problem is that it is possible to route the wire for collecting the material without lowering the carrier to the ground, and the carrier of the carrier at the time of moving the collecting site, etc. The purpose of the present invention is to provide a transporter for collecting materials that can be easily transported.
[0011]
[Means for Solving the Problems]
According to the first aspect of the present invention, the end of the return line is movably attached to the return line extending between the guide pulleys of the main column and the front column, and is turned back through the guide pulley of the front column.

[0027]
A material collecting operation using the transporter 2 will be described with reference to FIGS. 1 and 2.
[0028]
(1) Positioning of empty carrier:
The winch driver winds the pull-back line 38 of the empty loader 2 (the clamper 20 is detached) from which the timber 48 is lowered at the collecting place 50 on the main pillar 32 side, and the guide pulley 37 of the front pillar 34 is wound. At the end of the pull-back line 38 connected through, the pull-back line 44 is pulled back in the direction of the tip pillar 34 and sent to the target position near the wood 48 to be conveyed while being fed. When the transporter 2 reaches above the target position, the winch driver cooperates with the slinging operator to adjust the tension of the pull-back line 38 and bring the transporting unit 2 near the ground (for example, the height of the slinging worker's shoulder). ). At this stage, the slinging operator hangs the clamp portion 21 of the clamper 20 against the main pillar 32 side of the pull-back rope 38. When the winch driver makes the retracting cable 38 slightly wound up (in the direction indicated by the arrow P3), the main body 12 of the transporter 2 hung on the retracting cable 38 is guided by the front post 34. Pulled by the pulling cable 38 in the direction of the pulley 37, and the other is pulled by the clamper 20 and the connecting wire 22 through the pulling cable 38 in the direction of the guide pulley 36 of the main pillar 32, and is kept floating in the air. Is done. This state is maintained regardless of whether the drawing line 44 is wound or unwound.
[0029]
(2) Wire hook:
From the carrier 2 that has floated in the air, the slinging operator pulls the pulling line 44 that has been drawn out or released by the winch driver to the position of the wood 48 to be transported, and hangs on the wood 48 (R1 in FIG. 1). State).
[0030]
(3) Pulling wood to the carrier and removing the clamp:
When the pulling line 44 is hung on the wood 48, the winch driver pulls the pulling line 44 to the winder 2. Then, when the winch driver extends the tensioned pullback line 38 slightly in the direction of feed (in the direction indicated by the arrow P4), the connecting wire 22 connected to the clamper 20 is loosened, and the clamper 20 is automatically pulled from the pullback line 38. Come off. Since the clamper 20 is connected to the transporter 2 by the connecting wire 22, it does not fall off or be lost. The next clamping work can be done easily.
[0031]
(4) Transporting wood to the gathering location:
The winch driver winds up the pulling line 44 and feeds the pulling line 38, and draws the carrier 2 (the state of R2 in FIG. 1) in which the wood 48 is suspended to the collecting place 50 on the side of the main pillar 32. .
[0032]
The operation and effect of the collecting device 2 as described above will be described.
[0033]
(1) Facilitating sling work:
By fixing the travel of the transporter 2 to the pull-back line 38 by the clamper 20 of the fixing means 6, the transporter 2 can be held at a position floating from the ground at a target position where the wood is suspended. Accordingly, the pulling cable 44 hung on the wood is in a state of hanging from the airborne device 2, so that it is possible to easily perform operations such as pulling out a sling as compared with the case where the wire is pulled out and carried around from the conventional ground device. . Therefore, labor saving of the gathering work can be achieved.
[0034]
(2) Facilitating transport of transporters:
The transporter 2 further includes a clamper 20 when the pulley unit 10 and the main body unit 12 pull out the bolt 14b, and the main body unit 12 and the loading guide pulley 8 remove the shackle suspension 8a of the loading guide pulley 8. And the main body 12 can be easily separated by removing the shackle 18 and the tip of the pull-back line 38 and the main body 12 by removing the shackle 16. It is possible to easily carry the transporter when moving it.
[0035]
(3) Lighter transporter:
Since the transporter 2 includes the pulley unit 10, the single plate main body unit 12, and the load pulley 8, the transporter 2 itself is also simplified and reduced in weight. Therefore, even when the transporter needs to be moved in the handling of the wire or the like, the movement is easy.
[0036]
(4) Facilitation of carrying device:
Since the clamper 20 which is easy to operate is used as the fixing means 6 as means for fixing the traveling of the transporter 2 to the rope, it is possible to easily switch from the gathered state where the transporter 2 is fixed to the transported state where the fixing is released. . Further, since the clamper 20 is connected to the transporter 2 by the connecting cable 22, it is not lost. The clamper 20 can be operated with a single touch, and the carrier 2 is fixed to the pull-back line 38 as strongly as a load is applied via the connecting wire 22.
[0037]
(5) Reduction of logging costs:
The cost of collecting materials can be reduced by simplifying the structure of the transporter 2, facilitating wire handling work, simplifying overhead wire equipment, and facilitating transport of the transporter.
[0038]
