The drive source E, the rotating drum 5, the winch 6, and the operation unit 4 are provided in a construction machine such as a self-propelled power shovel having a crawler track or a forest work vehicle.

The transport rope 2 is suspended (strung) by a number of erection parts 30 having pulleys 3 provided between the felling land J and the logging ground S. The pulley 3 has a pair of upper and lower outer casings that form a concave circumferential groove, and the lower outer casing has a sprocket shape.
A large number (ten or more) of hook ropes 7 on which the felling material W is hung through a metal fitting 79 such as a hook member are attached to the transport rope 2. In other words, a number of hooking portions 21 including hooking ropes 7 on which the felling material W is hung are attached to the transport rope 2 at a number of locations.

As shown in FIGS. 4 and 5, the transport rope 2 is a transport cross rope 1 having a larger diameter (12 mm or more in a natural state) and a longer length (overall length of 50 m or more) than the hook rope 7. .
The hooking rope 7 is a hooking cross rope 9 having a smaller diameter (10 mm or less in a natural state) and a shorter dimension (100 mm or more and 500 mm or less) than the conveyance rope 2. The hook rope 7 is formed in a taper shape while preventing fraying by either or a combination of winding with an adhesive tape, adhesion with an adhesive, thermal fusion, or a combination of both ends.

  The cross rope 1 for conveyance and the cross rope 9 for hook are the same in structure (structure) except that the thickness and length are different, and strands 10 and 10 (90, 90) made of a large number of synthetic fibers are used. Six pairs, eight pieces, or twelve pieces of synthetic fiber rope formed into a hollow shape (cylindrical mesh bag shape) by superimposing (incorporating) the sets as two (bundle) pairs. It is also called. For example, it is used for sea anchors, buoy ropes, stationary nets and the like. Synthetic fibers are, for example, polyacid nylon, polyethylene, vinylon, polypropylene and the like. In order to obtain sufficient strength, it is preferable to use cross ropes 1 and 9 (12-strand synthetic fiber ropes) composed of 12 (bundle) strands 10 and 90. The carrying cross rope 1 is formed with a hollow portion 1e along the axis in a tension non-acting state (natural state or longitudinal compressive force acting state).

In FIG. 4, the hooking rope 7 is inserted in the longitudinal direction N of the conveying rope 2 whose opposite ends 7a and 7b are opposed to the conveying rope 2 from the outer peripheral surface so that the intermediate portion 7c is formed in a U-shaped curve. And inserted into the hollow portion 1e.
That is, one end 7a is inserted into the hollow portion 1e along one longitudinal direction N1 and the other end 7b is inserted into the hollow portion 1e along the other longitudinal direction N2 in a state where no tension is applied or a small pressure is applied. Yes. A number of hooking ropes 7 are attached in the longitudinal direction N of the transport rope 2. In other words, a hooking portion 21 formed with a U-shaped curved intermediate portion 7 c is attached to the transport rope 2.

Here, the method of connecting the transport rope 2 and the hooking rope 7 according to the present invention uses a rod-shaped insertion jig 8 as shown in FIGS. The insertion jig 8 for the hooking rope 7 is light and small and portable. As shown in FIGS. 6 and 7, a tip 81 formed in a hemispherical tip round shape, and a tip 81 A straight introduction portion (straight guide portion) 82 toward the base end portion 84 and a taper portion 83 that gradually increases in diameter from the diameter of the introduction portion 82 and contacts the base end portion 84 are provided. The base end portion 84 is formed to have a larger diameter than the introduction portion 82, and has a holding hole 85 that opens to the base end face 84a side and into which the end portion of the hooking rope 7 is inserted. In addition, the holding hole 85 is formed with an inner diameter that is smaller than the diameter of the hooking rope 7 in the natural state or in the radial compression-reduced state. Further, the holding hole 85 has a bottom surface 85a for hitting that regulates the amount of the hook rope 7 inserted. Further, a slit 86 is provided that divides the base end portion 84 and the taper portion 83 into a half.
As shown in FIG. 7, for example, when one end 7 a of the hooking rope 7 is inserted into the holding hole 85, the holding hole 85 is expanded in diameter by the slit 86 and is held like a collet by a restoring force (spring force). To prevent omissions.

  In FIG. 8, one end of the hooking rope 7 is inserted (connected) into the insertion jig 8. The longitudinal direction N1 side of the conveyance rope 2 (the middle part thereof) is compressed in the longitudinal direction N to expand the inner diameter in a bellows shape. That is, the hollow part 1e is enlarged. Further, the texture (knitting) between the strand 10 and the strand 10 is expanded. The distal end portion 81 and the introduction portion 82 of the insertion jig 8 connected to the transport rope 2 are inserted into the transport rope 2 whose diameter has been expanded from the outer peripheral surface. Further, one end of the hooking rope 7 is inserted together with the base end portion 84 of the insertion jig 8. The tapered portion 83 expands the diameter of the hollow portion 1e of the transport rope 2 and smoothly inserts the proximal end portion 84.

  As shown in FIG. 9, one end of one of the insertion jig 8 and the hooking rope 7 is inserted into the longitudinal direction N1 side by a predetermined dimension from the position where it is inserted into the conveyance rope 2, and penetrates the conveyance rope 2 obliquely in side view. In this way, the strands 10 and the weaves of the strands 10 are inserted in the longitudinal direction N1 side.

  As shown in FIG. 10, the insertion jig 8 is removed from the hooking rope 7. The hooking rope 7 is pulled back in the other longitudinal direction N2 side, and the hooking rope 7 is housed in the transport rope 2 without cutting one end 7a thereof.

  As shown in FIG. 11, the transport rope 2 into which the one end 7 a of the hooking rope 7 is inserted is pulled in the longitudinal direction N. Then, the hollow portion 1e of the transport rope 2 is reduced in diameter, and the one end 7a of the hooking rope 7 is tightened (pressed), and the one end (insertion portion) 7a of the hooking rope 7 is pressed by the frictional friction force (tightening frictional force). Connected strongly, never pull out.

  Then, as shown in FIG. 12, the other end 7 b of the hooking rope 7 and the insertion jig 8 are connected, the diameter of the intermediate portion of the transport rope 2 in the other longitudinal direction N 2 is increased, and the insertion jig connected to the transport rope 2 is connected. The distal end portion 81 and the introduction portion 82 of the tool 8 are inserted into the hollow portion 1e of the transport rope 2 whose diameter is increased from the outer peripheral surface, and the intermediate portion 7c of the hooking rope 7 is formed in a U-shaped curve. Further, the other end 7 b of the hooking rope 7 is inserted together with the base end portion 84 of the insertion jig 8. The insertion jig 8 is operated similarly to the case of the one end 7 a side, the other end 7 b of the hooking rope 7 is stored in the transport rope 2 without being cut, and the transport rope 2 is pulled in the longitudinal direction N.

As shown in FIG. 4, one end 7a of the hook rope 7 is connected to the longitudinal one direction N1 side of the transport rope 2 (the hook rope 7 and the transport rope 2 are unified on the one longitudinal direction N1 side). Is connected to the other longitudinal direction N2 side of the transport rope 2 (the hook rope 7 and the transport rope 2 are unified on the other longitudinal direction N2 side).
The transport rope 2 is subjected to a strong tensile force in the longitudinal direction N under the condition of use. With this tensile force, the strand 10 of the transport rope 2 composed of the cross rope 1 is narrowed so that the hollow portion 1e is reduced in diameter. As a result, the both ends 7a and 7b of the inserted hook rope 7 are not pulled out by a frictional force caused by pressure contact (tightening) (strongly connected).

  If the transport rope 2 is compressed in the longitudinal direction N, the space between the strands 10 and the strands 10 opens and the hollow portion 1e expands, so that both ends 7a and 7b of the hooking rope 7 are smoothly pulled out. The connection between the transport rope 2 and the hook rope 7 is easily released without the need for a tool, and the hook rope 7 (the hook portion 21) can be easily and quickly attached to and detached from the transport rope 2.

  Next, as shown in FIGS. 1 and 2, the transport rope 2 is composed of a plurality or a plurality of transport cross ropes 1, 1, one transport cross rope 1 (1 </ b> A) and the other transport rope. The cross ropes 1 (1B) are sequentially connected at the connecting portion 20 to form a closed loop (annular).

  As shown in FIG. 13, the structure of the connecting portion 20 and the formation method (connection method between the cross ropes 1A and 1B for transport) are one of the two cross ropes 1 and 1 for transport. The tip 12 on the one end 11 side of the cross rope 1A and the tip 14 on the other end 13 side of the other transporting cross rope 1B are arranged close to each other. Each cutting edge is prevented from being frayed by an adhesive tape or the like in the same manner as the hooking rope 7. Moreover, it is the structure (shape) similar to the insertion jig 8 for the hooking rope 7 demonstrated using FIG.6 and FIG.7, and a magnitude | size differs (the outer diameter size of each part and the inner diameter dimension of a holding hole are hooking ropes 7). Use an insertion jig for a transport rope (formed with a size larger than that of the above).

  First, the tip 14 of the other transport cross rope 1B is connected to an insertion jig. One end portion 11 of one conveying cross rope 1A is compressed in the longitudinal direction N to increase the diameter, and the texture between the strand 10 and the strand 10 is expanded. Insert the insertion jig connected to the tip 14 of the other conveyance cross rope 1B into one end portion 11 (the hollow portion 1e) of one of the conveyance cross ropes 1A whose diameter has been increased in one longitudinal direction N1. Let After a predetermined dimension is inserted in the longitudinal direction from the position inserted into the one end 11 of one of the cross ropes 1A for conveyance, the strand 10 and the strand 10 are pulled obliquely from the weave of the strand 10 and the strand 10 toward the longitudinal one direction N1. . Remove the insertion jig from the tip 14 of the other transporting cross rope 1B, pull back the other transporting cross rope 1B in the other longitudinal direction N2, and cut the tip 14 of the other transporting cross rope 1B. Instead, it is housed in one end 11 of one cross rope 1A for conveyance.

  Next, the tip 12 of one conveyance cross rope 1A is connected to the insertion jig, the other end 13 of the other conveyance cross rope 1B is expanded in diameter, and the other conveyance cross rope 1B is expanded. The distal end 12 of one conveyance cross rope 1A is accommodated in the end portion 13 without cutting, and the other end portion 13 of the other conveyance cross rope 1B is pulled in the longitudinal direction N.

Then, as shown in FIG. 14, the leading end 12 of one transport cross rope 1A is connected (stored) to the other end 13 of the other transport cross rope 1B, and the other transport cross rope 1B A connecting portion 20 is formed in which the tip end 14 is connected (stored) to one end portion 11 of one of the conveying cross ropes 1A. Then, a plurality of cross ropes 1 and 1 for conveyance are sequentially connected (forming the connecting portion 20) to form a closed loop conveyance rope 2.
Two cross ropes 1A and 1B are merged at both ends (positions) of the connecting portion 20 to form a merged portion, and two cross ropes 1A and 1B are formed at an intermediate portion (position) of the connecting portion 20. A bifurcated portion (separating portion) is formed in which the (center axis) is arranged in a divided state (divided into two).
Thus, by forming the connecting part 20 in a lip shape (bifurcated shape), it is possible to easily and quickly find the connected part (connecting part 20), and one cross rope 1A, 1B is provided at the branch part. It can be gripped one by one and can be easily separated.
Moreover, it is easy to insert the insertion jig 8 and the connection work can be performed quickly.

  Further, if the cross ropes 1A and 1B for transport on the swallowing (storage) side are compressed in the longitudinal direction N, the cross ropes 1A and 1B for transport on the inserted side are easily pulled out, and the connection portion 20 is connected. It is easily released. That is, the connecting portion 20 can be easily connected and disconnected, and is strong against the tensile force in the longitudinal direction N. Detachment is performed by a tightening force that reduces the diameter of the hollow portion 1e in a tensioned state. In addition, even the thickest part has about two cross ropes 1 for conveyance, and troubles such as catching between the pulley 3 and the rotating drum 5 are prevented.

Next, the effect | action of the felling material carrying-out apparatus of this invention, a conveyance rope, and a hook rope connection method is demonstrated.
In FIG. 1 thru | or FIG. 4, the construction route through which the conveyance rope 2 passes is provided so that it may pass through the vicinity of cutting objects, such as a tree and a bamboo. The closed-loop conveyance rope 2 is driven to circulate between the logging area S and the logging area J (from the logging area S to the logging area J). Appropriate tension acts in the longitudinal direction N by being drawn toward the operation unit 4 by the rotating drum 5 and the winch 6. The hollow portion 1e is reduced in diameter by the tension for driving and rotating the transport rope 2 and inserted into both ends 7a and 7b of the hook rope 7 inserted into the transport rope 2 and the connecting portion 20. A tightening force acts on the end of the carrying cross rope 1 to prevent it from coming off. The felling material W is connected to the hooking rope 7 (the hooking portion 21) via a hook 79, pulled by the transport rope 2, and carried out to the logging area S.

  A U-shaped curved hooking portion 21 projecting downwardly from the transport rope 2 is attached, and there are no unnecessary protrusions on the upper surface side and the left and right side surfaces of the outer surface of the transport rope 2, and a sudden There are no stepped portions or knots, and the hooking rope 7 is a flexible deformable rope. Therefore, the conveying rope 2 smoothly rotates without being caught by the rotating drum 5 or the pulley 3. .

Moreover, since the hooking rope 7 is detachable with respect to the conveyance rope 2, the pitch of the hooking ropes 7 can be changed flexibly and easily at the site, which contributes to the realization of efficient work.
Moreover, the length (insertion dimension) by which the hooking rope 7 is inserted into the transport rope 2 is adjustable, and the protruding length (hanging dimension) of the U-shaped curved intermediate part 7c can be adjusted to be long or short. Yes. In other words. A variety of hanging brackets 79 can be flexibly supported. Further, by inserting the one end 7a and the other end 7b close to or apart from each other, it is possible to form a narrow or wide U-shaped curve. That is, the width dimension of the U-shaped curved intermediate portion 7c is adjustable. In other words, the size of the hook portion 21 can be easily changed.

  In addition, the cutting of the transportation rope 2 near the erection route is completed, and the length of the transportation rope 2 is set to the site in order to extend / add the suspension route to the vicinity of the next logging object or to avoid obstacles. Need to be extended (added) or shortened accordingly. The hooking rope 7 is easily attached to the extended part (the newly added transport cross rope 1), and the hook rope 7 is easily separated from the shortened part (the transport cross rope 1 that is no longer needed). .

  Further, the extension or shortening of the transport rope 2 can be achieved by releasing the connection of the connecting portion 20 of the transport rope 2 and adding or reducing the number of transport cross ropes 1 to form the connecting portion 20 sequentially. A transport rope 2 having a desired length is obtained. They are connected without the use of special connection fittings or the formation of a complicated ice braid. The erection route can be changed freely (sequentially) flexibly according to the surrounding environment (situation) such as terrain. There is no need for a large cutting machine such as a hydraulic cutter that requires a drive source or a connecting fitting for connection, and the work of extending and shortening the transport rope 2 can be performed efficiently and quickly.

Next, in another embodiment, the hooking portion 21 of the transport rope 2 is different from the above-described embodiment, and the other is the same configuration.
As shown in FIG. 15, the transport rope 2 (transport cross) is formed so that the intermediate portion 7c is formed in a U-shaped curve with the end 7a and the other end 7b of the hook rope 7 at a predetermined interval in the longitudinal direction N. The strand 1 and the strand 10 are inserted from the direction substantially orthogonal to the axis of the rope 1), and the one end 7a and the other end 7b through which the transport rope 2 is inserted are bundled as shown in FIG. An annulus is formed. A hook portion 21 is formed by the suspension ring portion. By inserting the strand 10 between the strands 10 in the vertical direction (substantially vertical direction), the positional displacement in the longitudinal direction is prevented, and in addition, the tension between the strand 10 and the strand 10 of the transport rope 2 in the tensioned state. The frictional force is increased by the force and the engagement between the strand 10 of the conveying rope 2 and the strand 10 of the hooking rope 7.

  The design of the present invention can be changed, and after the one end 1a or the other end 7b of the hooking rope 7 is stored together with the insertion jig 8 in the transport rope 2, only the insertion jig 8 is pulled out, and the transport rope 2 A method in which the one end 7a or the other end 7b is left in the connection is also possible. That is, after introducing the one end 7 a and the other end 7 b into the transport rope 2, a method of removing only the insertion jig 8 from the transport rope 2 may be used. Similarly, the connection between the transport ropes 2 (formation of the connecting portion 20) may be removed in such a manner that only the insertion jig for the transport rope 2 is inserted after the leading ends 12 and 14 are introduced.

  As described above, the felling material carry-out device of the present invention is provided with the felling material carry-out device 2 that is suspended in a closed loop between the felling land J and the lumbering land S and driven around and pulls the felling material W.
