Description

  The present invention relates to a method for collecting felled trees used for collecting thinned wood, logs, and other fallen trees that have been cut in a mountain forest in a gathering place.

  Thinned wood, logs, and other fallen trees that have been felled in the forest until now are gathered and transported from the harvested point to a gathering place near the road such as a forest road, and branches and leaves are used at this gathering place using a predetermined heavy machine. In addition, a method is used in which the sheet is cut into a predetermined length, loaded on a truck, and conveyed to a sawmill or the like.

  By the way, the method described below has been adopted as a logging method for transporting felled trees cut down in the mountain forest to the logging site. In this conventional gathering method, a main line (or main rope) made of a wire rope is stretched (or stretched or aerial) from the above-mentioned gathering place in the direction of inclination of the forest, and traveled while being guided by the main line.・ Mounting the transporter that can be moved (providing a cableway) On the other hand, on the lower side of this main line, the wire is fed out from one winch fixed in the vicinity of the above yard, and the hook is fixed at the tip Are arranged so as to form a part parallel to the main line. In addition, the other winch is disposed in the vicinity of the main line, a pulley is attached to the other end of the main line, the wire constituting the other winch is passed over the pulley, and the tip is fixed to the carrier. To do. Then, the carrier on one end side of the main line is moved and moved to the other end side (position where the felled tree is present) of the main line by driving the other winch, and then the hook constituting the one winch Is locked to a felled tree or a locking wire or rope wound around the felled tree, and then the one winch is driven on the felled tree from the felling point (position where the felled tree exists). This is a method of moving and conveying in the direction of the gathering place (see Patent Document 1). In such a material collecting method, after the other winch is driven and one carrier is moved to the other end side of the main line, the hook constituting the one winch is locked to the felled tree, and after this is finished, In this method, one of the winches is driven to wind the wire, thereby moving the felled tree together with the transporter moving in the direction of the gathering field, and then removing the hook constituting the one winch from the felled tree. In other words, the conventional gathering method described above is a method of gathering felled trees at a gathering place by reciprocating one carrier by driving one and the other winch alternately.

JP-A-5-51197

  By the way, the gathering method performed by reciprocating the carrier as in the above-described conventional gathering method, etc., is the logging that has been gathered and transferred to the gathering place where one end of the main line is fixed. A logging side operator who performs the work of removing the hook from the fallen tree, and a felling side work that engages the fallen tree with the hook constituting the one winch in the vicinity of the main line or in the vicinity thereof. Gathering work is carried out by each person performing work at each location. However, in such a gathering method so far, for example, when the logging side worker finishes the operation of locking the hook to the felled tree, the transporter reciprocates again and the logging side (position where the felled tree exists). In the same way, the worker on the side of the yard gathers again when the work to remove the felled tree transferred to the side of the yard from the hook is completed. We have to wait until we return to the lumber mill, and workability has deteriorated significantly. Incidentally, the gathering work of collecting and transporting felled trees to the gathering place is an extremely severe work performed on an unstable slope. On the other hand, Japan's forestry industry is exposed to price competition with cheap timber imported from abroad and has lost its competitiveness, coupled with the harsh working environment and rising labor costs. The sales volume of timber in Japan has declined, and as a result, the deforestation of forests is progressing. Therefore, the efficiency of gathering work that has been carried out in the forestry so far contributes to the competitiveness of imported wood and contributes to securing workers or creating jobs.

  Therefore, the present invention has been proposed in order to solve the problems of the above-described conventional method for collecting felled trees, and the felled trees cut down in the mountain forest are collected very efficiently to the gathering ground. The purpose is to provide a new method for collecting felled trees that can increase the price competitiveness of domestic timber, promote employment creation in forestry, and prevent the deforestation of forests. .

  The present invention has been proposed in order to solve the above-mentioned problems, and the first invention (the invention according to claim 1) is one of the wire rods formed along the inclined direction of the inclined surface of the forest. The main line and the other main line are extended in parallel with each other or inclined so that one end side or the other end side of the one main line and the other main line are separated from each other. A first carrier having a pulley is disposed in a state where it can run while being guided by the one main line, and a second carrier having a second pulley is guided to the other main line on the other main line. The first hook is fixed to the tip of the first hook that is locked to the felled tree or the winding wound around the felled tree at one end of the one main line. The first winch having the wire is fixed, and the middle part of the first wire is A second wire fixed to the tip of a second hook hooked to a felled tree or a winding wound around the felled tree is attached to one pulley of the other main line. And fixing the second winch having the intermediate portion of the second wire to the second pulley, and connecting one end of the connection line to either the first carrier or the second carrier. Connect the other end of the connection line to the other transporter different from the transporter to which the one end is connected, or connect one end of the connection line to either the first transporter or the second transporter The other end of the connection line is connected to the one end of the connection line, and the other end of the connection line is connected to the one end of the connection line. And using a plurality of connecting line pulleys, the middle part of the connecting line is connected to the one main line or A first carrier that is guided by the one main line by supporting the connection line so that a portion parallel to the main line is formed, driving the first winch and the second winch alternately And the second carrier guided by the other main line are alternately reciprocated so that the felled tree engaged with the first or second hook on the other end side of the one and other main lines is The one and the other main lines are alternately transferred to one end side or the first or second winch side.

  In the method for collecting felled trees according to the first invention, for example, when the first carrier is located on the first winch side (one end side of one main line), the second carrier is the first carrier. It is located in the other end side of the other main line rather than one carrier. Contrary to this positional relationship, when the second transporter is located on one end side of one main line, the first transporter is located on the other end side of the other main line with respect to the second transporter. Is located. In addition, in the case where the first or second carrier is located on one or the other main line side, the distance between the two depends at least on the length of the connecting line. In the case where the lengths of the one and the other main lines are constant, the longer the length of the connection line, the shorter the distance between the two in the positional relationship, and the shorter the length of the connection line (one and the other) The distance between the two in the positional relationship becomes longer. And when the 1st carrying device and the 2nd carrying device exist in the position explained previously, the work which removes the felled tree conveyed with the movement of the 1st carrying device from the 1st hook is made, At this time, in a place where the second transporter is located, an operation of locking the second hook on the felled felled tree or the winding wound around the fallen tree is performed. And the operation | work which removes the felled tree transferred to the one end side of said one main line from a 1st hook, and the operation | work which latches a felled tree to the 2nd hook in the other end side of the other main line are complete | finished. Then, the second winch is driven, and the second wire constituting the second winch is wound up. At this time, the first winch is kept free. When the driving of the second winch is started, the fallen tree is drawn to the second pulley, and when the second pulley and the fallen tree come close to each other as much as possible, the second transporter then guides the other main line. While being done, it gradually moves to the second winch side (one end side of the second main line). At this time, the second transporter and the first transporter are connected to each other by the connection line, and the middle part of the connection line is parallel to the one main line and the other Since the middle part is supported by a plurality of pulleys for connecting lines so that a part parallel to the main line is formed, the first transporter has the same distance as the travel distance of the second transporter. Move to the other end of one main line. When the second transporter moves (arrives) to one end side (second winch side) of the other main line, the first transporter arrives at a position close to the place where the second transporter was originally located. To do.

  Therefore, by using the method for collecting felled trees according to the first aspect of the present invention, it is extremely efficient to collect the logs as compared with the conventional method of collecting the logs by reciprocating a single carrier. Work (double work amount) can be realized.

  The one main line and the other main line are preferably stretched so as to be parallel to each other, but slightly inclined so that one end side or the other end side of the one main line and the other main line approach each other. And may be stretched. Each of the first and second transporters includes a mechanism or configuration (for example, a pulley or the like) supported and guided by at least the one main line or the other main line, and a first or second winch. Or what is necessary is just to provide the 1st or 2nd pulley over which the middle part of the 2nd wire is spanned, and the said 1st and 2nd pulley may be single or may be plural. In addition, the distance between the one main line and the other main line need only be such a distance that there is no obstacle such as collision when at least one and the other carrier pass each other, and the situation at the work site and the number of workers What is necessary is just to determine suitably by etc.

  In addition, according to a second invention (invention of claim 2), in the first invention, between the one end of the connection line and the first carrier, or the other end of the connection line and the second carrier. A plurality of adjusting wire members each having a connecting portion formed in a straight line, and arranged between one end of the connecting line and the first carrier or the connection A loop-shaped adjustment wire that can change the length of the circumference is arranged at least either between the wire and the second carrier, and the number of the adjustment wires is appropriately increased or decreased or the length of the circumference By changing the height, the distance between the first carrier and the second carrier when the first carrier or the second carrier is located closest to one end of the one main line or the other main line is changed. It is characterized by transporting felled trees while

  In the method for collecting felled trees according to the second invention, one end of the connection line constituting the first invention is connected to either the first or second carrier, and the other end of the connection line is connected, A plurality of adjustment wires or a single adjustment wire is further used for one connected to a carrier different from the carrier to which one end of the connection line is fixed. In the method for collecting felled trees according to the second aspect of the invention, the above-described adjusting wire is arranged between the first or second carrier and one end or the other end of the connection line to collect the felled trees. For this reason, felled trees cut down in a mountain forest can be collected by the method described below. For example, the plurality of adjusting wire rods are arranged so that the second transporter when the first transporter is located on one end side of the most main line is positioned, for example, 20 m away from the first transporter. It arrange | positions (intervenes) between the carrying device and one end of the connection line, or between the second carrying device and the other end of the connection line. When the second winch is driven or the first winch is driven thereafter as described above with the adjusting wire interposed, the distance between the first carrier and the second carrier is 20 m. It will reciprocate over. That is, according to this method, it is possible to collect felled trees that have been felled at a position about 20 m away from the gathering place on one end side of the one and the other main lines. Thereafter, when the number of the adjustment wires is decreased or increased, or when the loop-shaped adjustment wires are used, if the length of the circumference is shortened or lengthened, the first carrier and the second carrier The distance from the carrier becomes shorter or longer. For example, if the length of the first carrier and the second carrier is shortened, the first and second carriers over a distance longer than 20 m from one end side (gathering site) of the one and the other main lines. Will reciprocate, and conversely, if the lengths of the first and second transporters are increased, the distance from the one end side (gathering field) of the one and the other main lines will be shorter than 20 m. Each of the first and second transporters will reciprocate. Normally, felled trees harvested at a position close to the gathering ground are gathered, and then gathered while gradually increasing the distance from the gathering ground. In such a case, more adjustment wires may be connected in a straight line in advance, and then the adjustment wires may be removed in order. In addition, when using a loop-shaped adjusting wire, the length of the circumference is lengthened and arranged (intervened) at the above position, and then the length of the circumference is gradually shortened, Work becomes possible.

  The method for collecting felled trees according to the second aspect of the present invention includes at least one of the connection line and the first carrier, or at least one of the connection line and the second carrier. This is a method of collecting felled trees by arranging (intervening) adjusting wires in the transporter. Therefore, as described above, the adjustment wire is disposed only between one end of the connection line and the first transporter or between the other end of the connection line and the second transporter, Furthermore, you may arrange | position both between the one end of a connection line, and a 1st carrier, and between the other end of this connection line, and a 2nd carrier. The adjustment wire may be individual adjustment wires each having a connecting portion formed therein, and a plurality of the adjustment wires may be connected in a straight line, or the straight wire may be bent into a loop and the loop A single adjusting wire that can change the length of the circumference, or an adjusting wire formed by connecting a plurality of such adjusting wires may be used.

  Further, according to a third invention (invention according to claim 3), in the first invention, one end of the connection line is connected to the other end of one of the first carrier and the second carrier. Then, by connecting the other end of the connection line to one end of the one carrier, the connection line is disposed endlessly with the first carrier or the second carrier interposed therebetween. The other transporter, which is different from the one transporter to which the connection line is connected, is locked in the middle of the connection line, and the locked state between the other transporter that has locked the connection line and the connection line is released. By changing the stopping position and locking again, the first carrier and the second carrier when the first carrier or the second carrier is located closest to one end of the one main line or the other main line and the second carrier It is characterized in that felled trees are transferred while changing the distance from the carrier.

  In the method for collecting felled trees according to the third invention, the first (one) transporter (or the second transporter / the other transporter) is interposed between one end and the other end. The connection line arranged in is used. Therefore, the first (one) transporter (or the second transporter / the other transporter) drives the first winch (or the second winch) so that one main line (or the other main line) is driven. When traveling / moving while being guided, a second (other) transporter different from the first (one) transporter (or the second transporter / the other transporter) is also engaged in the middle of the connection line. Since it is stopped, the first (one) transporter (or the second transporter / the other transporter) moves in the opposite direction. For example, the second transporter (the other transporter) in the case where the first transporter (one transporter) is located on one end side of the most main line is at a position (for example) 20 m away from the first transporter. In this manner, the second carrier (the other carrier) is locked to the connection line. In such a state, when the second winch is driven or the first winch is subsequently driven, the first carrier and the second carrier (with respect to one or the other carrier) span a distance of 20 m. Will reciprocate. That is, according to this method, it is possible to collect felled trees that have been felled at a position about 20 m away from the gathering place on one end side of the one and the other main lines. After that, when the locking position of the second carrier (the other carrier) with respect to the connection line is moved / changed to the other end side or one end side of the other main line and is locked to the connection line again, the most main line The distance between the first transporter and the second transporter (the distance from one or the other transporter) in the state of being located on one end side of the is increased or decreased. For example, if the distance between the first transporter and the second transporter (distance with one or the other transporter) is shortened, the distance is longer than 20 m from one end side (gathering field) of the one and the other main lines. The first and second transporters (one and the other transporter) will reciprocate over each other, and conversely the distance between the first transporter and the second transporter (distance with one or the other transporter) is increased. If it does so, the 1st and 2nd carrying device (one or the other carrying device) will reciprocate over the distance shorter than 20 m from the one end side (gathering place) of the said one and the other main line, respectively. Normally, felled trees harvested at a position close to the gathering ground are gathered, and then gathered while gradually increasing the distance from the gathering ground, so it is located on one end side of the most main line In the state where the distance between the first transporter and the second transporter (one or the other transporter) is shortened, the second (other) transporter (or the first transporter / one transporter) is connected to the connection line. One and the other main lines by locking the middle part and transferring the felled tree, and then gradually increasing the distance between the first carrier and the second carrier (distance with one or the other carrier) It is possible to collect felled trees that have been felled at a position away from one end side (gathering ground).

  According to a fourth invention (invention of claim 4), the first intermediate pulley and the second pulley are arranged in a direction perpendicular to the length direction of the one or other main line constituting the invention of the third invention. The intermediate pulley is attached to the first intermediate pulley, and the first wire constituting the first winch or the second wire constituting the second winch is in the middle of the wire. The second intermediate pulley, the other wire that is the first wire or the second wire and is different from the wire that is passed over the first intermediate pulley, The tip of one wire spanned over one intermediate pulley is fixed at a position separated from the first intermediate pulley in a state where the midway portion of the one wire intersects the one main line and the other main line. And this one wire has a third pulley with a third pulley. A transporter is arranged in a state where it can run while being guided by the one wire, and a midway portion of the other wire that is stretched over the second intermediate pulley is stretched over the third pulley, and the one wire A third winch is fixed in the vicinity of the tip of the third winch, and the tip of the third wire drawn out from the third winch is connected to the third transporter to be hooked on the first intermediate pulley. While using one of the wires passed from the middle part to the tip as the third main line, the third carrier guided by the third main line and the hook fixed to the tip of the other wire Utilizing and transferring the felled tree cut in the direction perpendicular to the one and the other main lines to the one and the other main lines, and then performing the third lumbering method It is.

  In the method for collecting felled trees according to the fourth aspect of the present invention, for example, a first (one) wire constituting the first winch (or the second winch) that is a component of the third aspect of the invention ( Alternatively, the intermediate portion of the second wire / the other wire is stretched over the first intermediate pulley (or the second intermediate pulley), and the first (one) wire (or the second wire / the other wire). ) Is fixed at a position separated from the first intermediate pulley (or the second intermediate pulley) in a state in which the middle portion intersects one or the other main line, and the first (one) ) On the wire (or the second wire / the other wire), the second carrier provided with the third pulley is disposed in a state where it can run, and the second carrier is stretched over the second intermediate pulley. The third pulley in the middle of the other wire (or the first wire / one wire) The third winch is fixed in the vicinity of the tip of the first (one) wire (or the second wire / the other wire), and the third winch pulled out from the third winch The tip of the wire is fixed to the third carrier. Therefore, in the state where the third carrier is located on the base end side (first intermediate pulley side) of the first (one) wire (or the second wire / the other wire), When the third winch is driven while the one winch (or the second winch) is in a free state, the third carrier carries the first (one) wire (or the second wire / the other). Move to the third winch side while being guided by the wire). The second pulley (or the first hook) having the second hook (or the first hook) fixed to the tip is provided on the third pulley constituting the third transporter moved to the predetermined position in this way. Since the middle part of (or the first wire / one wire) is stretched over, the second hook (or the first hook) is attached to the felled tree or the winding wound around the felled tree. Lock and drive the second winch (or first winch) on it. At this time, the third winch is kept free. Then, the third transporter moves in the direction in which the second intermediate wheel side (or the first intermediate pulley side), that is, one or the other main line is stretched. In addition, when transferring a felled tree separated in the direction orthogonal to the one or the other main line to the one or the other main line by using the third carrier, it is close to the one or the other main line. It is preferable to collect the felled trees collected at a position and gradually collect the felled trees that have been fell at a position away from the one or the other main line.

  When the second hook (or the first hook) is locked to a specific felled tree or a winding wound around the felled tree, the second winch (or the first winch) is free. In addition to the felled tree that exists immediately below the third transporter, the felled tree that has been felled in the vicinity of the third transporter can also be transferred, but the second winch (or As long as the length of the second (other) wire (or first wire / one wire) constituting the first winch allows, the second (other) wire (or first wire) is allowed. The wire / one wire) may be stretched and the number of felled trees existing at a position away from the third carrier may be collected. However, it is extremely severe for the worker to move the forest through the second wire (or the first wire) in this way to the felled trees existing at a position away from the third carrier. Therefore, when the work of collecting felled trees in the vicinity of the moving range of the third carrier on the one or other main line side is completed, the position of the first and second intermediate pulleys, While moving to one end side or the other end side of one or the other main line, the first (one) wire (or the second wire / the other wire) whose tip has been fixed until then is removed, and the first And the second intermediate pulley is moved and fixed in the same direction as that of the second intermediate pulley, and the third winch is disposed near the tip of the one of the newly fixed wires. The same transfer / gathering is performed using the above. When such a collecting operation is completed, the collecting method according to the third aspect of the invention is then performed.

  Therefore, according to the method for collecting felled trees according to the fourth aspect of the present invention, the felled trees harvested at the site where one wire that is the first wire or the second wire is stretched or in the vicinity thereof are described above. It can be easily transferred to one or the other main line. In addition, as described above, the first and second intermediate pulleys are moved to one end side or the other end side of one or the other main line, and the first wire or the second wire whose front end has been fixed until then. One of the two wires is removed and moved in the same direction as the moving direction of the first and second intermediate pulleys to be newly fixed, and the third winch is newly fixed. When the same material is collected again by using the third carrier etc. again, there is no need for the operator to reciprocate to a place considerably away from the third carrier. Therefore, the burden on the operator can be further reduced.

  The first intermediate pulley and the second intermediate pulley may be separated from each other, but a so-called double pulley in which the respective rotation shafts are the same axis may be used. good.

Further, a fifth invention (invention according to claim 5) is the one wire constituting the fourth invention, wherein any position between the tip of the one wire and the third carrier In addition, a fourth carrier equipped with a fourth pulley and a fifth pulley capable of removing the suspended wire is fixed in a state of being movably supported with respect to the one wire. The third intermediate pulley is fixed at a position separated from the fourth carrier, and one hook and the other hook are attached to the tip of the third wire constituting the third winch. Provided, the middle portion of the third wire spans the fourth pulley, the third intermediate pulley, and the fifth pulley, and locks the one hook to the third carrier, A second or first hook having the other hook fixed to the tip of the one wire; And the third winch is moved to an arbitrary position in the length direction of the one wire by the driving of the third winch, and is then suspended over the fifth pulley until then. The third wire that has been removed is removed from the fifth pulley, and the one hook previously locked to the third carrier is removed from the third carrier,
Next, by driving the third winch, the tip of the third wire and the tip of the other wire that is the second or first wire locked to the other hook are moved to the fourth wire. Move to an arbitrary position between the transporter and the third intermediate pulley, and engage with a felled tree cut near the position or a winding wound around the felled tree, and then the second By driving the winch or the first winch, the felled tree is moved to the vicinity of the fourth carrier, and then the middle part of the third wire is passed over the fifth pulley, and then the second pulley is moved. By driving the winch No. 2 or the first winch, the felled tree is transferred to the one or the other main line side, and then the lumber gathering method according to the third invention is performed.

  In the fifth aspect of the invention, for example, the third winch is driven in a state where the third transporter is positioned in the vicinity of the first or second intermediate pulley (in this case, the second or first The third winch is moved closer to the fourth transporter, and conversely (with the third winch free) the first or second winch. By driving, the third transporter moves away from the fourth transporter. The operation of the third transporter is the same as that of the fourth invention. When the third transporter reaches an arbitrary position, the third wire that has been stretched over the fifth pulley until then is removed from the fifth pulley, and the third transporter until then. The one hook hooked to the second carrier is removed from the third transporter, and then the third winch is driven, whereby the tip of the third wire and the second hook hooked to the other hook are engaged. Alternatively, the tip of the other wire, which is the first wire, is moved to an arbitrary position between the fourth carrier and the third intermediate pulley. When the tip of the third wire and the tip of the other wire are moved in this way, the third winch and the second or first winch are kept free. Then, the second hook or the first hook fixed to the tip of the second wire or the first wire is locked to the felled tree or the winding wound around the felled tree. Then, the fallen tree is moved to the vicinity of the fourth carrier by driving the second or first winch while keeping the third winch in a free state, and then the third wire is moved. A midway portion is passed over the fifth pulley, and then the second winch or the first winch is driven to collect felled trees on the one or other main line side. When such a material collecting method is completed, the material collecting method according to the third invention is first performed.

  By such a gathering method or process, it is possible to easily gather felled trees that have been cut between or near the fourth carrier and the third intermediate pulley. After the completion, if the fixing position of the fourth carrier is changed and the fixing position of the third intermediate pulley is also changed, it is possible to further widen the gathering range, and more gathering work. The efficiency of the can be improved.

  Therefore, according to the method for collecting felled trees according to the fifth aspect of the present invention, not only the vicinity of one or the other main line described above or the range close to the movable range of the third carrier, It is easy and easy to collect even felled trees that have been felled between and near the transporter 4 and the third intermediate pulley, and the efficiency of gathering is significantly higher than that of conventional gathering methods. This can improve the harsh working environment, and can sufficiently contribute to improving the competitiveness of domestic timber.

  In the fifth aspect of the present invention, the fixed position of the third intermediate pulley is not necessarily set at a position parallel to the length direction of one or the other main line described above from the fourth carrier. The one main line or the other main line may be inclined with respect to the length direction. Further, the third intermediate pulley may be fixed further forward than the other end of the one or other main line (the side opposite to the side on which the first winch or the second winch is fixed). . By fixing the third intermediate pulley at such a position, felled trees can be collected over a wider range.

  In the method for collecting felled trees according to the first invention (the invention described in claim 1), the first winch and the second winch are alternately driven, whereby the first main line guides. By alternately reciprocating the first carrier and the second carrier guided by the other main line, the first or second hook is engaged with the first or second hook. The fallen tree is gathered alternately on one end side of the one and the other main lines or on the first or second winch side. For example, it is possible to realize a highly efficient gathering operation (double work amount) as compared with the conventional gathering method performed by reciprocating a single carrier.

  Moreover, in 2nd invention (invention of Claim 2), at least any one between the one end of a connection line and the said 1st carrier, or between the other end of this connection line, and the said 2nd carrier When the first carrying device or the second carrying device is located closest to one end side of the one main line or the other main line, for example, by arranging the adjusting wire described above and appropriately increasing or decreasing the number of the adjusting wires. Since the gathering is performed while changing the distance between the first carrier and the second carrier in the above, according to the method for gathering felled trees according to the second invention, one end side of one or the other main line The fallen trees existing on the other end side can be gathered in order, and the fallen trees fell over a wide range can be gathered easily and efficiently.

  In the third invention (the invention described in claim 3), the locking state between the carrier and the connection line, which is different from the carrier in which both ends of the connection line are fixed, is released, the locking position is changed, and the engagement is performed again. By stopping, while changing the distance between the first transporter and the second transporter when the first transporter or the second transporter is located closest to one end of the one main line or the other main line Since it is for gathering, even in the case of the felling tree gathering method according to the third invention, as in the second invention, from one end side of the other main line to the other. The felled trees existing on the end side can be gathered in order, and the fallen trees felled over a wide range can be gathered easily and efficiently.

  In the fourth invention (invention according to claim 4), the third main line is used while using one wire from the midway portion to the tip of the first intermediate pulley as the third main line. The felled tree cut in the direction orthogonal to the one and the other main line using the third carrier guided by the first and the hook fixed to the tip of the other wire, the one and the other main line And collecting the felled tree according to the fourth aspect of the present invention. In addition to the felled trees existing in the vicinity of one or the other main line as in the invention of 3, the felled trees existing in the direction perpendicular to the length direction of the one or the other main line are also collected easily and efficiently. be able to. In addition, the first and second intermediate pulleys are moved to one end or the other end of one or the other main line, and the first wire (or the second wire) whose tip has been fixed until then. ) Is removed and moved in the same direction as the moving direction of the first and second intermediate pulleys to be newly fixed, and the tip of the one wire to which the third winch is newly fixed By arranging in the vicinity and collecting the same material again using the third transporter or the like, it becomes possible to easily and efficiently collect felled trees existing over a wider area.

The second hook 62b is fixed to the tip of the second wire 62a. Note that the first wire 61a or the second wire spanned around the first pulley 21 or the second pulley 22 are respectively provided in the leading end side middle portions of the first wire 61a and the second wire 62a. A stopper 61c (62c) for preventing the 62a from falling off is attached.

In the method for collecting felled trees according to this embodiment, the first transporter 11 and the second transporter 12 are connected by a connection line 63. The connection line 63 is composed of a wire rope, and one connection line side hook 63a is fixed at one end, and the other connection line side hook 63b is fixed at the other end. The one connection line side hook 63a is locked to the other locking member 43 constituting the first transporter 11, and the other connection line side hook 63b is connected to the second transporter 12. It is latched by the other latching tool 44 which comprises. Further, the middle portion of the connection line 63 is stretched over a first connection line pulley 65 and a second connection line pulley 66. It said first connection line pulleys 65 is mounted through the wire to trees T ₂ to which the other end said one main line to the side 1 of one of the main line 1 above is fixed (reference numeral is omitted.) in addition, the second connection line pulleys 66 are mounted through the wire to trees T ₄ the main line 2 of said other on the other side of the other main line 2 is fixed (reference numeral is omitted.) (See FIG. 1). The connection line 63 is parallel to the one main line 1 from one end side to a portion spanned by the first connection line pulley 65, and is connected to the second connection line from the other end side. The portion spanned on the pulley 66 is parallel to the other main line 2. In the first embodiment, the length of the connection line 63 is the same as the length of one main line 1 and the other main line 2, and the first connection line pulley 65 and the second connection line. The length is approximately equal to the length to the pulley 66.

  Therefore, hereinafter, a method for collecting felled trees W in the state set in the above-described configuration will be described. First, the first winch 61 is driven and the second winch 62 is set in a free state. As shown in FIG. ), As described above, the length of the connection line 63 is equal to the length of the one main line 1 and the other main line 2, and the first connection line pulley 65 and the second connection are connected. Since the length is approximately equal to the length to the line pulley 66, the second transporter 12 is located on the other end side of the other main line 2. Therefore, in a state where the second transporter 12 is located on the other end side of the other main line 2, the wire rod wound around the felled tree W cut in the vicinity of the second transporter 12 (reference numerals are omitted). ) Is engaged with the second hook 62b. When the second winch 62 is in a free state, if the operator grasps and pulls out the second hook 62b, the second wire 62a is extended, so that the worker can It is possible to engage with the felled tree W existing in the vicinity of the second transporter 12 or within the range where the second hook 62b reaches in accordance with the length of the second wire 62a. Then, when such work is finished, when the second winch 62 is driven (with the first winch 61 in a free state), the felled tree W gradually moves to the second transporter 12 side, and eventually the above The second stopper 62c comes into contact with the cover 20, and the second transporter 12 travels and moves to one end side of the second main line 2 while being guided by the other main line 2, and arrives at the position shown in FIG. At this time, the driving of the second winch 62 is stopped, and the felled tree W locked on the second hook 62b is removed. As described above, when the second transporter 12 reaches one end side of the other main line 2, the first transporter 11 is located on the other end side of the one main line 1, as shown in FIG. Therefore, the worker performs an operation of locking to the felled tree W existing in the vicinity of the first hook 61b in the same manner as the above-described procedure.

  As described above, the first winch 61 and the second winch 62 are alternately driven, and the first carrier 11 and the second carrier 12 are alternately reciprocated, whereby one main line and the other main line. In the yard where one end of 1 and 2 is fixed, the work of removing the felled tree W moving by the first or second transporter 11 or 12 arriving alternately from the first or second hook 61b or 62b On the other hand, on the other end side of one and the other main lines 1 and 2, an operation for locking the felled tree W fell in the vicinity thereof to the first or second hook 61 b or 62 b is performed. Therefore, it is possible to increase the work efficiency by a factor of two compared to the conventional method for collecting felled trees W using a single carrier.

  Next, a method for collecting felled trees according to the second embodiment of the present invention will be described in detail. As shown in FIGS. 5 and 6, the method for collecting felled trees according to the second embodiment is configured to collect a plurality of adjustment wires 70 on the connection line 63 described in the above-described method of collecting trees. Is what you do. As shown in FIG. 7, the adjustment wire 70 is fixed to the wire main body 70a made of a wire or the like, a locking fitting 70b fixed to one end of the wire main body 70a, and the other end of the wire main body 70a. And a locking ring 70c. Then, in the method for collecting felled trees according to the second embodiment, as shown in FIG. 5, a plurality of adjustment wire rods 70 are connected using the locking metal fittings 70b and the locking rings 70c. The coupled adjustment wire group (reference numerals are omitted) is coupled between the first carrier 11 and one end of the connection line 63, and between the second carrier 12 and the other end of the connection line 63. Connected in between. That is, on the first transporter 11 side, the locking metal fitting 70b constituting the adjustment wire 70 connected to one end side is locked to the other locking tool 43, and the adjustment wire 70 connected to the other end is connected. The constituting locking ring 70c is locked to the one connecting line side hook 63a. On the second transporter 12 side, the locking metal fitting 70b constituting the adjustment wire 70 connected to the other end side is locked to one locking tool 44 constituting the second transporter 12, and is attached to one end. The locking ring 70c constituting the connected adjustment wire 70 is locked to the other connection line side hook 63b. In addition, when using the said adjustment wire 70 mutually connected, the number of this adjustment wire 70 is suitably selected according to the reciprocation distance of the said 1st or 2nd transporters 11 and 12, or the progress of the gathering work. If the number of adjustment wire rods 70 is increased, the total length, which is the sum of the length of the adjustment wire rod group and the length of the connection wires, is increased. Therefore, the first and second transporters The reciprocating distance of the first and second carriers 11 and 12 is shortened if the length of the adjustment wire group is shortened. Normally, when collecting many fallen trees W fell in the mountain forest at the gathering site, the gathering (transfer) from the felled trees W that are located close to the gathering site in order. Uses a relatively large number of adjusting wire rods 70, and removes the necessary number of adjusting wire rods 70 as needed as the collecting and transferring operations gradually proceed.

  For example, as shown in FIG. 5, when three adjustment wires 70 are arranged on each of the first carrier 11 side and the second carrier 12 side, the first carrier 11 is one end of the most main line 1. When located on the side, the second transporter 12 is closer to one end side of the other main line 2 than the position shown in FIG. 3. Then, from the state shown in FIG. 5, the second winch 62 is driven (with the first winch 61 in a free state) to move to the other end side of the other main line 2 as shown in FIG. To do. Further, from the state shown in FIG. 6, by driving the first winch 61 (with the second winch 62 in a free state), the first and second transporters 11 and 12 are again in the state shown in FIG. Return to. That is, according to the method for collecting felled trees according to the second embodiment, the first and second winches 61 and 62 are connected after the adjustment wire 70 is linearly connected by an appropriate number. By alternately driving, it becomes possible to gather and transfer the felled tree W existing at the midpoint of the one and the other main lines 1 and 2 to the gathering place. The length of one and the other main lines 1 and 2 is increased by increasing (or decreasing) the number of adjusting wire rods 70 and changing the reciprocating distances of the first and second transporters 11 and 12 to perform gathering. The felled tree W within the range can be collected easily and quickly.

  In the above embodiment, a plurality of adjusting wire rods 70 are disposed both between the first carrier 11 and one end of the connection line 63 and between the second carrier 12 and the other end of the connection line 63. Although the method of collecting and collecting the felled tree W has been described, the adjustment wire 70 may be arranged and connected to either the first transporter 11 side or the second transporter side for gathering. good.

  Further, in the above-described method for collecting felled trees, a plurality of adjustment wires 70 are connected to each other, but the adjustment wires constituting the present invention may use a single adjustment wire 71. good. As shown in FIG. 8, the adjustment wire 71 is formed by bringing one end side and the other end side of a wire 72 made of one wire or the like into contact with each other and holding and fastening them using a holding metal fitting 73. The loop portion 72a is formed, and the portion where the loop portion 72a is formed is inserted into a ring portion 74a formed at the base end of the hook 74. The holding metal fitting 73 includes a U-shaped bolt member 73a, a holding body 73b through which the bolt member 73a is inserted, and a middle portion of the wire 72 in cooperation with the bolt member 73a, and the bolt member 73a. And two nuts 73c screwed to both ends. Therefore, the length of the loop portion 72a can be changed by changing the holding position by the holding metal fitting 73. The hook 74 is locked to the other locking tool 43 constituting the first transporter 11 or the other locking tool 44 constituting the second transporter 12, and the loop portion 72 a is connected to the connecting line 63. The distance from the first transporter 11 to the second transporter 12 can be changed by engaging with one connection line side hook 63a or the other connection line side hook 63b fixed to one end of the As described above, the fallen tree W within the range of the lengths of the one and the other main lines 1 and 2 can be collected easily and quickly in the same manner as when a plurality of adjusting wire rods 70 are used.

Next, a method for collecting felled trees according to the third embodiment of the present invention will be described in detail. As shown in FIG. 9, this gathering method is such that the connection line 63 described above is long, and one connection line side hook 63a fixed to one end of the connection line 63 is connected to the first carrier. 11, the other connecting line side hook 63 b fixed to the other end of the connecting line 63 is locked to one locking tool 41, The connection line 63 is wired in a loop with the transporter 11 interposed. In addition to the first and second connection line pulleys 65 and 66, the midway part of the connection line 63 hangs over the third and fourth connection line pulleys 77 and 78. The third connection line pulleys 77, the wire to trees T ₃ which is fixed one end of the other main line 2 (reference numeral is omitted.) Are supported via, also, the pulley for the fourth connection line 78 Is supported on a standing tree T ₁ to which one end of the one main line 1 is fixed via a wire (reference numeral is omitted). Therefore, the connection line 63 from the fourth connection line pulley 78 to the first connection line pulley 65 with the first carrier 11 interposed therebetween is straight and parallel to the one main line 1. The connecting line 63 extending from the third connecting line pulley 77 to the second connecting line pulley 66 is in a state of being extended in parallel with the other main line 2. The second transporter 12 is locked and clamped by the clamping members 46 and 48 in the middle of the connection line 63 from the third connection line pulley 77 to the second connection line pulley 66. ing.

  Therefore, in the state shown in FIG. 9, when the second winch 62 is driven (the first winch 61 is in a free state), the connection line 63 is connected to the first carrier 11 and the second carrier 12 together. 9, the first carrier 11 travels and moves to the other end side of one main line 1, and the second carrier 12 moves to the other main line as shown in FIG. Runs and moves to one end of 2. Such operations are the same as the operations described in the first embodiment and the second embodiment, respectively, and thus the description thereof is omitted.

Then, in the state shown in FIG. 9, the nuts 57, 57, 58, 58 (see FIG. 2) constituting the clamping members 46, 48 constituting the second transporter 12 are screwed out, and the bolt members 50, 52 are with releasing the clamping state of the Kyojitai 54,56, to move the carriage 12 of the second to the other main line 2 on one end side (standing T ₃ side or the second winch 62 side), on the again By screwing the nuts 57, 57, 58, 58, the connecting wire 63 is clamped and fixed by the bolt members 50, 52 and the clamping bodies 54, 56. By moving the second transporter 12 by such a method, both the second range 12 and the first transporter 11 span the distance from the second transporter 12 to one end of the other main line 12. Will be able to reciprocate. That is, the locking position or the fixing position with respect to the connecting line 63 (running from the third connecting pulley 77 to the second connecting line pulley 66) is changed by the above-described method and process. By doing this, it is possible to achieve the same effect as the method for collecting felled trees performed using the plurality of adjustment wires 70 and the single adjustment wire 71 described in the second embodiment. In particular, according to the method for collecting felled trees according to the third embodiment, since there is no need to use the adjustment wire rods 70 and 71, the first and second transporters 11 and 12 can be more easily used. It is possible to change the reciprocating distance.

Next, a method for collecting felled trees according to the fourth embodiment will be described in detail with reference to FIG. The method for collecting felled trees according to the fourth embodiment is based on the configuration shown in FIGS. 9 and 10, and further includes a double pulley 80, a third carrier 81, and a third carrier described below. This is a method of collecting lumber using a winch 82. The double pulley 80 is arranged (fixed) in a direction orthogonal to the length direction of one and the other main lines 1 and 2. The double pulley 80 is fixed slightly below the stretched position of the one and the other main lines 1 and 2, and both the first intermediate pulley 80a and the second intermediate pulley 80b rotate. It is provided freely. In addition, the first wire 61a hung over the first pulley 21 is stretched over the first intermediate pulley 80a, and the middle portion thereof is hung over. Then, the first wire 61a is not cross the one and the other of the main lines 1 above, the leading end is fixed to the standing trees T _12. Then, utilizing a first portion which is stretched from the intermediate pulley 80a to trees T ₁₂ constituting the double pulley 80 (the one of the wires constituting the present invention) as the main line. The tip of the first wire 61a to be utilized in the vicinity of the trees T ₁₂ which is fixed, is installed and fixed the third winch 82 as the main line. A third hook 82b is fixed to the tip of the third wire 82a constituting the third wire 82.

  A third transporter 81 is supported by the first wire 61a used as the main line (one wire constituting the present invention) so as to be able to run while being guided by the first wire 61a. The third transporter 81 has the same configuration as the first and second transporters 11 and 12, and includes a transporter body 84, one and other traveling pulleys 85 and 86, and a third pulley 89. , One and the other locking devices 87, 88 and the like. And the 3rd hook 82b which comprises the said 3rd winch 82 latches to the other latching tool 88 which comprises the said 3rd carrying device 81. FIG. Further, the second wire 62a constituting the second winch 62 is further pulled out from the state shown in FIG. 9 or FIG. 10, and is passed over the second intermediate pulley 80b constituting the double pulley 80, and thereafter It spans over the third pulley 89 that constitutes the third transporter 83.

Then, the third winch 82 is driven (while the second winch 62 is in a free state), the third transporter 83 is moved from the fixed position of the double pulley 80 to an arbitrary position, The second wire 62a is pulled out and locked to a nearby felled tree W by the second hook 62b. In this state, when the second winch 62 is driven (with the third winch 82 in a free state), the second hook 62b pulled out together with the locked felled tree W is in the third carrier 83. When the stopper 62c comes into contact with the case 89a, the third carrier 83 is gradually guided below the other main line 2 or one main line 1 while being guided by the first wire 61a used as the main line. To reach. In this state, the driving of the second winch 62 is stopped, and the felled tree W is removed from the second hook 62b. When these operations are completed, the third winch 82 is then driven, and the third transporter 83 is moved and moved to a predetermined position. That is, while driving alternately said third winch 82 and a second winch 62, and the third first the double pulley 80 and the trees T ₁₂ along the wire 61a which functions carriage 83 as the main line of By reciprocating between the two, the felled tree W existing in a direction orthogonal to the one and the other main lines 1 and 2 is collected on the one and the other main lines 1 and 2 side. Then, when such a gathering operation is completed, the gathering is performed on one end side of one and the other main lines 1 and 2 using the method described above with reference to FIGS. 9 and 10.

  Therefore, according to the above-mentioned method for collecting felled trees, the one and other main lines 1, 2 and other members described with reference to FIG. 9 and FIG. By utilizing, the felled tree W felled in the direction orthogonal to the one and the other main lines 1 and 2 can be collected.

In the case where the fixed position of the tip of the first wire 61a from the fixed position of the double pulley 80 (standing position of the T ₁₂₎ collecting material felled W up to the present has been completed, then the double pulley 80 The fixed position of the first wire 61a is moved to one end side (or the other end side) of the one and the other main lines 1 and 2 and fixed again, and the position for fixing the tip of the first wire 61a is also moved and fixed in the same direction. In addition, it is also possible to collect the materials by the same method and procedure as described above. In the above-described material collecting method according to the fourth embodiment, an example in which the double pulley 80 is fixed to one main line 1 side in FIG. 11 has been described. Alternatively, the other main lines 1 and 2 may be arranged and fixed in the opposite direction. Incidentally, when such a method is adopted, the second wire 62a is stretched over the first intermediate pulley 80a and the tip thereof is fixed and used as a main line, and the second intermediate pulley 80b is used. In this case, the first wire 61a is hung and the tip end side is hung on the third pulley 89.

  Next, a method for collecting felled trees according to the fifth embodiment will be described in detail with reference to FIGS. The method for collecting felled trees according to the fifth embodiment is based on the method for collecting felled trees described with reference to FIG. 11, and further includes a fourth carrier 90, a third intermediate pulley 91, This is done using.

In the method for collecting felled trees according to this embodiment, the third wire 82a constituting the third winch 82 described above is passed over the fourth pulley 95, and then the third pulley It is hung on the intermediate pulley 91 and further on the fifth pulley 96. A fourth hook 82c is formed at the tip of the third wire 82a in addition to the third hook 82b described above. On the other hand, in the vicinity of the second hook 62b, a ring 62d to which the third hook 82b is locked is fixed or fitted. Then, the third hook 82b is locked to the ring 62d, and the fourth hook 82c is locked to the other locking tool 88 constituting the third transporter 83.

The fourth transporter 90 is fixed at an arbitrary position of the first wire 61a used as the main line so as not to move along the first wire 61a. The fourth carrier 90 may be fixed by, for example, fixing a wire rod (reference numeral is omitted) to the horizontal rod 98 using the nearby standing trees T ₁₄ and T ₁₅ . Further, the fixing position of the third intermediate pulley 91 may be a position separated from the fixing position of the fourth carrier 90, for example, in the length method of the one or other main lines 1 and 2 described above. Alternatively, the length method of the one or the other main lines 1 and 2 may be fixed at an inclined position.

  For example, when the fourth transporter 90 and the third intermediate pulley 91 are fixed and installed in the state shown in FIG. 12, first, the third winch 82 is driven, and the third transporter is driven. 81 is moved to the fourth carrier 90 side. At this time, the second winch 62 is kept free. When the third transporter 81 is moved to an appropriate position, the third wire 82a that has been stretched over the fifth pulley 96 until then is removed from the fifth pulley 96, and until then. The fourth hook 82c that has been locked to the other locking tool 88 constituting the third transporter 81 is removed from the other locking tool 88. As a result, the operator can extend each of the third winch 82 and the second winch 62 in a state where the third wire 82a and the second wire 62a are connected to each other. On the other hand, the second hook 62b can be locked. Then, when the second hook 62b is locked to the felled tree W in this way, the second winch 62 is then driven slightly (with the third winch 82 left free). The second wire 62a is wound up, and then the second wire 62a is passed over the fifth pulley 96 again, or the second winch 62 is not driven at all. The middle part of 62a is again passed over the fifth pulley 96, and then the second winch 62 is driven. Then, when the second hook 62b approaches the third pulley 89 together with the felled tree W and the stopper 62c fixed in the vicinity of the second hook 62b comes into contact with the case 89a, the third transporter 81 is Then, along the first wire 61a used as the main line, it gradually moves away from the fourth carrier 90 and moves to the one and other main lines 1 and 2 shown in FIG.

Then, when the operation of moving the felled tree W existing between the fixed position of the fourth transporter 90 to the third intermediate pulley 91 or in the vicinity thereof to the one and the other main lines 1 and 2 is completed, The fixed position of the fourth carrier 90 and the fixed position of the third intermediate pulley 91 are moved to, for example, the distal end side or the proximal end side (the one and the other main lines 1 and 2 side) of the first wire 61a. Fix it again and do the same. Then, when the work of transferring a number of felled trees W to the vicinity of or below the one and the other main lines 1 and 2 is completed by the above method, then, according to the method described above as the third embodiment, One side of the main line 1 or 2 on the other side of the felled tree W (gathering ground)
Gather.

  Therefore, if the felling tree gathering method according to the fifth embodiment described above is compared with the felling tree gathering method according to the third embodiment, by adopting this gathering method, The operator does not need to repeatedly reciprocate between the third carrier 81 and a position considerably away from the third carrier 81 while holding the second hook 62b. Further, according to this gathering method, the fixed position of the double pulley 80 shown in FIG. 11 is set to the other end side of the one and the other main lines 1 and 2, so that It is also possible to collect the felled tree W felled on the end extension line side.

  In addition, when the felling tree gathering method according to the fifth embodiment is adopted, the gathering method described with reference to FIG. The felled trees present in the vicinity are gathered, and then the double pulley 80 shown in FIG. 11 is fixed at a position relatively close to one and the other main lines 1 and 2, and the tip of the second wire 62 a And in the direction orthogonal to the other main lines 1 and 2, adopting the felling tree gathering method according to the fourth embodiment described above, after such a gathering method is finished, again the third implementation It is desirable to adopt the order of performing the gathering method according to the form. According to this method of gathering, highly efficient gathering work is achieved while preventing the fallen tree W that is not gathered and the moving fallen tree W from colliding and causing damage and reducing the value of the product. can do.

  In the description of each of the above embodiments, for example, one and the other main lines 1 and 2, the first wire 61a, or the connecting line pulleys 65 and 66, the double pulley 8, the third intermediate pulley 91, etc. Are supported and fixed using standing trees (reference numerals are omitted), but these may not necessarily use standing trees but may use poles or other separate members. The third winch 82 preferably has a size and weight that can be carried by an operator and can be started and stopped by remote control. By using this type of winch as the third winch 82, it is possible to simplify the movement, and in the work of stretching the one and the other main lines 1 and 2 over a long distance, By using the third hook 82b that constitutes the third winch 82 to lock and carry the other ends of the one and the other main lines 1 and 2, it becomes possible to reduce severe work. .
