以下、図示の実施形態に基づき本発明を詳説する。
本発明の修羅設置方法は、図18に示すように、伐採材等の滑走対象物Wを滑走させるたに、山間部等の斜面に設置される樋状の滑道60を形成する方法である。
図1及び図2に示すように、滑道60を形成するための修羅部材70の搬送開始位置となる低位置Sから搬送すべき位置である高位置Jにわたって、修羅部材70を牽引する搬送ロープ2を架設する。
Hereinafter, the present invention will be described in detail based on illustrated embodiments.
As shown in FIG. 18, the shura installation method of the present invention is a method of forming a bowl-like runway 60 installed on a slope such as a mountainous area in order to slide a sliding object W such as a felled timber. .
As shown in FIGS. 1 and 2, a transport rope that pulls the shura member 70 from a low position S, which is a transport start position of the shura member 70 for forming the slide 60, to a high position J that is a position to be transported. 2 is installed.

搬送ロープ2は、複数本の中空状のクロスロープ1,1から成り、周回駆動される前に、複数本のクロスロープ1,1の内、一方のクロスロープ1(1A)と他方のクロスロープ1(1B)を連結部20にて順次接続して形成する。   The transport rope 2 is composed of a plurality of hollow cross ropes 1 and 1, and before being driven around, one cross rope 1 (1A) and the other cross rope of the plurality of cross ropes 1 and 1. 1 (1B) are sequentially connected at the connecting portion 20.

ここで、連結部20の形成方法は、図4に示すように、2本のクロスロープ1,1の内、一方のクロスロープ1Aの一端部11の先端12と、他方のクロスロープ1Bの他端部13の先端14を、接近させて配設する。各先端12,14に粘着テープ等を巻着しほつれを防止する。
クロスロープ1は、多数本の合成繊維から成るストランド10を、2本(束)1組として、その組を交互に重ね合わせて(組み込んで)中空状(円筒網袋状)に形成した、六つ打ち、又は、八つ打ち、或いは12打ち合成繊維ロープとも呼ばれるものとする。例えば、シーアンカー、ブイロープ、定置網等に使用される。合成繊維は、例えば、ポリアシド系ナイロン、ポリエチレン、ビニロン、ポリプロピレン等である。なお、十分な強度を得るために、本発明は、12本(束)のストランド10から成るクロスロープ1(12打ち合成繊維ロープ)とするのが好ましい。なお、クロスロープ1(1A,1B)を以下「ロープ」と呼ぶ場合もある。
Here, as shown in FIG. 4, the connecting portion 20 is formed by the other end of one cross rope 1A of the two cross ropes 1 and 1, and the other cross rope 1B. The tip 14 of the end 13 is disposed close to the end 13. Wrap adhesive tape around each end 12, 14 to prevent fraying.
The cross rope 1 is formed as a hollow (cylindrical mesh bag shape) in which strands 10 made of a large number of synthetic fibers are made into two (bundles) as a set, and the sets are alternately stacked (assembled). It shall also be called a one-punch, eight-punch, or twelve-pitch synthetic fiber rope. 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, the present invention is preferably a cross rope 1 (12-strand synthetic fiber rope) composed of 12 (bundle) strands 10. The cross rope 1 (1A, 1B) may be hereinafter referred to as “rope”.

図5に示すように、他方のロープ1Bの他端部13側の先端14を、棒状の挿入治具8に接続する。
挿入治具8は、現場に持ち込まれる前に、予め、軽量・小型な携帯自在に形成され、図3及び図5に示すように、半球状の先端丸型の先端部81と、先端部81から基端部84に向かってストレート状の導入部(ガイド部)82と、導入部82の直径から次第に拡径して基端部84と接するテーパ部83と、を有する形状に形成されている。基端部84は導入部82より大径に形成され、基端面84a側に開口すると共にロープ1が差し込まれる保持孔85を形成している。また、保持孔85は、ロープ1の自然状態乃至ラジアル方向圧縮縮径状態の直径より小さな寸法の内径寸法で形成されている。また、保持孔85に、ロープ1の差込量を規制する当り用の底面85aを形成している。また、基端部84及びテーパ部82を半割り状にするスリット86を形成している。
図5に示すように、例えば、他方のロープ1Bの先端14を保持孔85に差し込むと、スリット86によって保持孔85が拡径すると共に復元力(バネ力)によって、他方のロープ1Bの先端14及び他端部13をコレットのように挟持状に保持して抜けを防止する。
As shown in FIG. 5, the tip 14 on the other end 13 side of the other rope 1 </ b> B is connected to a rod-shaped insertion jig 8.
The insertion jig 8 is formed in advance so as to be lightweight and small and portable before being brought into the field. As shown in FIGS. 3 and 5, the hemispherical tip end 81 and the tip 81 The guide portion 82 is formed in a shape having a straight introduction portion (guide portion) 82 from the base end portion 84 toward the base end portion 84 and a tapered portion 83 that gradually increases in diameter from the diameter of the introduction portion 82 and contacts the base end portion 84. . The base end portion 84 is formed to have a larger diameter than the introduction portion 82, and forms a holding hole 85 into which the rope 1 is inserted while opening on the base end face 84a side. The holding hole 85 is formed with an inner diameter smaller than the diameter of the rope 1 in the natural state or in the radial compression-reduced state. Further, a bottom surface 85a for hitting that restricts the amount of insertion of the rope 1 is formed in the holding hole 85. In addition, a slit 86 is formed in which the base end portion 84 and the taper portion 82 are halved.
As shown in FIG. 5, for example, when the tip 14 of the other rope 1B is inserted into the holding hole 85, the diameter of the holding hole 85 is expanded by the slit 86 and the restoring force (spring force) causes the tip 14 of the other rope 1B. The other end 13 is held like a collet to prevent it from coming off.

図6に於て、一方のロープ1Aの一端部11を、長手方向に圧縮して蛇腹状に内径を拡径すると共に、ストランド10とストランド10の間の織目(編目)を広げる。ロープ1Bと接続した挿入治具8の先端部81及び導入部82を、長手一方向N1に、拡径したロープ1Aの一端部11に挿入する。こうすることで、一方のロープ1Aの先端12をほぐして(ストランド10毎に分けて)、先端開口部を形成して他方のロープ1Bを挿入する必要がなくなり作業性が向上する。   In FIG. 6, one end 11 of one rope 1A is compressed in the longitudinal direction to increase the inner diameter in a bellows shape, and 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 rope 1B are inserted into one end portion 11 of the rope 1A having an enlarged diameter in one longitudinal direction N1. By doing so, it is not necessary to loosen the tip 12 of one rope 1A (divided for each strand 10) to form a tip opening and insert the other rope 1B, thereby improving workability.

図7に示すように、一方のロープ1Aの一端部11に、挿入治具8の基端部84と共に他方のロープ1Bの先端14を挿入する。テーパ部83によって、一方のロープ1Aの一端部11が拡径してスムーズに基端部84が挿入される。
図8に示すように、挿入治具8及び他方のロープ1Bの先端14を、一方のロープ1Aの一端部11を、挿入した長手方向反対側のストランド10とストランド10の編目から引き抜くように挿通させる。
As shown in FIG. 7, the distal end 14 of the other rope 1B is inserted into the one end 11 of one rope 1A together with the base end 84 of the insertion jig 8. By the taper portion 83, the one end portion 11 of the one rope 1A is expanded in diameter, and the base end portion 84 is smoothly inserted.
As shown in FIG. 8, the insertion jig 8 and the tip 14 of the other rope 1B are inserted so that one end 11 of one rope 1A is pulled out from the inserted strand 10 and strand 10 on the opposite side in the longitudinal direction. Let

図9に示すように、他方のロープ1Bの先端14から挿入治具8を取り外す。そして、他方のロープ1Bを長手他方向N2に引き戻し、他方のロープ1Bの先端14を、一方のロープ1Aの一端部11に収納させる。
図10に示すように、他方のロープ1Bの先端14を内有する一方のロープ1Aの一端部11を、長手方向に引っ張る。すると、一方のロープ1Aが縮径し、他方のロープ1Bの先端14を締め付けて摩擦力を増加させると共に、一方のロープ1Aのストランド10と他方のロープ1Bのストランド10が互いに係止して(かみ合って)抜けが防止される。
As shown in FIG. 9, the insertion jig 8 is removed from the tip 14 of the other rope 1B. Then, the other rope 1B is pulled back in the other longitudinal direction N2, and the tip 14 of the other rope 1B is stored in one end 11 of the one rope 1A.
As shown in FIG. 10, one end 11 of one rope 1A having the tip 14 of the other rope 1B is pulled in the longitudinal direction. As a result, the diameter of one rope 1A is reduced, the tip 14 of the other rope 1B is tightened to increase the frictional force, and the strand 10 of one rope 1A and the strand 10 of the other rope 1B are locked together ( Occurrence is prevented).

そして、図11に示すように、一方のロープ1Aの先端12と挿入治具8を接続し、他方のロープ1Bの他端部13を拡径させ、上述のように挿入治具8を操作して、他方のロープ1Bの他端部13に、一方のロープ1Aの先端12を収納させて、他方のロープ1Bの他端部13を長手方向に引っ張る。
すると、図12に示すように、一方のロープ1Aの先端12が他方のロープ1Bの他端部13に接続し、他方のロープ1Bの先端14が一方のロープ1Aの一端部11に接続された、連結部20が形成される。このようにして形成された連結部20は、接続金具等が不要で、長手方向の引っ張り力に強く、太さも連結部20の中央部20aでロープ2本程度と成り、後述の滑車3及び回転ドラム5との間で引っ掛かり等の不具合が防止される。
Then, as shown in FIG. 11, the tip 12 of one rope 1A and the insertion jig 8 are connected, the other end 13 of the other rope 1B is expanded in diameter, and the insertion jig 8 is operated as described above. Then, the other end 13 of the other rope 1B is accommodated with the tip 12 of one rope 1A, and the other end 13 of the other rope 1B is pulled in the longitudinal direction.
Then, as shown in FIG. 12, the tip 12 of one rope 1A is connected to the other end 13 of the other rope 1B, and the tip 14 of the other rope 1B is connected to one end 11 of the one rope 1A. The connecting portion 20 is formed. The connecting part 20 formed in this way does not require a connection fitting or the like, is strong against a tensile force in the longitudinal direction, has a thickness of about two ropes at the central part 20a of the connecting part 20, and has a pulley 3 and a rotation described later. Problems such as catching with the drum 5 are prevented.

また、一方のロープ1Aの一端部11を長手方向に圧縮すれば、一方のロープ1Aの内径が拡径して、スムーズに他方のロープ1Bの先端14が引き抜かれる。また、他方のロープ1Bの他端部13を長手方向に圧縮すれば、他方のロープ1Bの内径が拡径して、スムーズに一方のロープ1Aの先端12が引き抜かれ、容易に連結部20の接続は解除される。
上述のように接続・分離自在な連結部20を構成し、複数本のクロスロープを順次連結部20にて接続して搬送ロープ2を形成する。
Further, if one end 11 of one rope 1A is compressed in the longitudinal direction, the inner diameter of one rope 1A is expanded, and the tip 14 of the other rope 1B is smoothly pulled out. Further, if the other end 13 of the other rope 1B is compressed in the longitudinal direction, the inner diameter of the other rope 1B is increased, and the tip 12 of one rope 1A is smoothly pulled out, so that the connecting portion 20 can be easily pulled out. The connection is released.
As described above, the connecting portion 20 that can be connected and separated is configured, and a plurality of cross ropes are sequentially connected by the connecting portion 20 to form the transport rope 2.

また、図13に示すように、搬送ロープ2に修羅部材70が掛けられる引掛部21を形成する。
図14に示すように、可撓性を有する紐体7の一端7aと他端7bを、所定の間隔をもって、クロスロープ1の軸心略直交方向からストランド10とストランド10の間を挿通させ、クロスロープ1を挿通した一端7a側部と他端7b側部を、図13に示すように、結束して、垂下状の吊り輪を形成する。
このように、紐体7を用いることで後述の回転ドラム5との間で引っ掛かり等の不具合が防止される。また、フック部材79で引っ掛けるだけで連結でき、作業性を向上させている。また、クロスロープ1と紐体7を工具なしで接続でき、引掛部21を容易に増減できる。また、引掛部21と引掛部21のピッチ寸法を容易に変更できる。
Further, as shown in FIG. 13, a hooking portion 21 on which the shawl member 70 is hung on the transport rope 2 is formed.
As shown in FIG. 14, one end 7a and the other end 7b of the flexible cord body 7 are inserted between the strand 10 and the strand 10 from the direction substantially perpendicular to the axis of the cross rope 1 with a predetermined interval. As shown in FIG. 13, the one end 7a side portion and the other end 7b side portion inserted through the cross rope 1 are bound to form a hanging suspension ring.
In this way, the use of the string 7 prevents problems such as catching with the rotary drum 5 described later. Further, it is possible to connect by simply hooking with the hook member 79, and the workability is improved. Moreover, the cross rope 1 and the string body 7 can be connected without a tool, and the hook portion 21 can be easily increased or decreased. Moreover, the pitch dimension of the hook part 21 and the hook part 21 can be easily changed.

また、図1及び図2に示すように、搬送ロープ2を周回駆動させるための回転ドラム5と、搬送ロープ2に適度な張り(テンション)を付与するためのウインチ(巻取り機)6と、パワーシャベル等の建設機械や林内作業車等のエンジンや油圧モータ又は電気モータ等の駆動源Eと、回転ドラム5とウインチ6を夫々操作可能な操作部9と、をトラック等の運搬車両が侵入可能な搬送開始位置となる低位置Sに配設している。駆動源Eと回転ドラム5とウインチ6と操作部9は、具体的には履帯を有する自走可能なパワーショベル等の建設機械や林内作業車等に設ける。   Moreover, as shown in FIG.1 and FIG.2, the rotating drum 5 for driving the conveyance rope 2 around, the winch (winding machine) 6 for providing moderate tension | tensile_strength (tension) to the conveyance rope 2, A transport vehicle such as a truck enters a construction machine such as a power shovel, a drive source E such as an engine, a hydraulic motor or an electric motor of a forest work vehicle, and an operation unit 9 capable of operating the rotating drum 5 and the winch 6 respectively. It is disposed at a low position S that is a possible transfer start position. Specifically, the drive source E, the rotary drum 5, the winch 6, and the operation unit 9 are provided in a construction machine such as a self-propelled power shovel having a crawler track or a work vehicle in a forest.

また、回転ドラム5に、搬送ロープ2を2回(2巻)以上巻き付ける。
また、低位置Sから高位置Jにわたって、滑道60を形成すべき場所の近傍に配設搬送ロープ2を懸架させるための架設部30を形成する。
また、回転ドラム5及びウインチ6の間に回転ドラム5の引込み方向と、ウインチ6の引っ張り方向を同方向とする折り返し用の滑車3(3B)を有する架設部30を形成する。
また、閉ループ状の搬送ロープ2に、ウインチ6で張りを付与するためのテンション用の滑車3(3A)を有する架設部30を形成する。
Further, the transport rope 2 is wound around the rotating drum 5 twice (two turns) or more.
In addition, from the low position S to the high position J, an installation portion 30 for suspending the arranged transport rope 2 is formed in the vicinity of the place where the runway 60 is to be formed.
Further, a erection part 30 having a folding pulley 3 (3B) is formed between the rotating drum 5 and the winch 6 so that the retracting direction of the rotating drum 5 and the pulling direction of the winch 6 are the same direction.
In addition, an erection portion 30 having a tension pulley 3 (3A) for applying tension with the winch 6 is formed on the closed loop-shaped conveyance rope 2.

図15に示すように、架設部30を、低位置Sや高位置Jに存在する樹木や竹等又は打設した杭等から成る支柱部31と、支柱部31に巻設され可撓性の帯状乃至紐状体を有する締め付けベルト等の締結部材32と、搬送ロープ2が懸架される回転体(プーリ)39を有する滑車3と、で構成する。   As shown in FIG. 15, the erection part 30 is composed of a pillar part 31 made of trees, bamboo, or the like existing in the low position S or the high position J, or a pile piled up, and a flexible part wound around the pillar part 31. A fastening member 32 such as a fastening belt having a belt-like or string-like body and a pulley 3 having a rotating body (pulley) 39 on which the transport rope 2 is suspended are configured.

図15(a)に示すように、滑車3を、締結部材32によって支柱部31に水平軸心La廻りに揺動自在に取着する。搬送ロープ2にテンションが付与されていない自然状態では、支柱部31に締結部材32を介して垂下状とし、搬送ロープ2にテンションが付与されると、図15(b)に示すように、回転体39側が上方へ揺動し、回転体39の回転軸心L3が鉛直状に回転可能にするように取着する。なお、鉛直状とは、水平面に対して、60度乃至120度の範囲を言う。   As shown in FIG. 15A, the pulley 3 is attached to the column 31 by a fastening member 32 so as to be swingable around the horizontal axis La. In a natural state where no tension is applied to the transport rope 2, the support 31 is suspended by a fastening member 32, and when tension is applied to the transport rope 2, as shown in FIG. The body 39 side swings upward, and the rotating shaft L3 of the rotating body 39 is attached so that it can rotate vertically. The vertical shape means a range of 60 degrees to 120 degrees with respect to the horizontal plane.

滑車3は、架設現場に持ち込まれる前に、予め、軽量・小型で持ち運び自在に形成され、図16と図17に示すように、回転体39の円周凹溝39dから搬送ロープ2が下方に脱落するのを防止する底壁部39aを形成している。底壁部39aを、回転軸心L3周りに所定の間隔で上下方向に開口する切欠部39bを形成したスプロケット状(歯車状)に形成している。言い換えると、回転体39の底面側に、搬送ロープ2が下方に脱落するのを防止する係止突片39cを回転軸心L3周りに所定の間隔に形成している。
つまり、搬送ロープ2の引掛部21が回転体39に懸架される際に、吊り輪状の紐体7が、切欠部39b(係止突片39cと係止突片39cの間)から垂れ下がり、回転体39に引っ掛かることなく、垂下状態が保持され、搬送ロープ2のスムーズな周回駆動を可能に形成している。
Prior to being brought into the construction site, the pulley 3 is formed in advance so as to be lightweight, small and portable, and as shown in FIGS. 16 and 17, the transport rope 2 extends downward from the circumferential concave groove 39d of the rotating body 39. A bottom wall 39a is formed to prevent the dropout. The bottom wall portion 39a is formed in a sprocket shape (gear shape) in which cutout portions 39b that open in the vertical direction at predetermined intervals around the rotation axis L3 are formed. In other words, locking protrusions 39c that prevent the transport rope 2 from dropping downward are formed on the bottom surface side of the rotating body 39 at predetermined intervals around the rotation axis L3.
That is, when the hooking portion 21 of the transport rope 2 is suspended from the rotating body 39, the hanging ring-like string body 7 hangs down from the notch 39b (between the locking protrusion 39c and the locking protrusion 39c) and rotates. The hanging state is maintained without being caught by the body 39, and the transport rope 2 can be driven smoothly.

A substantially straight main line portion 75 is formed from the upstream side to the downstream side, and a sub-line portion 76 that is inclined in a plan view and extends obliquely from the downstream side to the upstream side at a predetermined inclination angle θ from the axis 75a of the main line portion 75 is formed. . It is more preferable that the inclination angle θ is less than 90 degrees and less than 45 degrees so that when the sliding object W slides from the auxiliary line portion 76, it smoothly flows to the narrow downstream end portion 72. In addition, the main line portion 75 and the sub-line portion 76 have an upstream end width dimension Xa larger than the downstream end width dimension Xb to form an upstream wide shape, and a wide upstream end portion 71 and a narrow downstream end portion 72 are formed.

It is possible.

また、図23(b)に示すように、投入口用修羅部材70Cの側壁77を下流側から上流側に向かって低くなるように側面視傾斜状に形成する。
また、投入口用修羅部材70Cの幅狭下流端部72を、テーパ型修羅部材70Bの幅広上流端部71に載置した際に、投入口用修羅部材70Cの側壁77の下流側が、テーパ型修羅部材70Bの側壁77の上流側より上方(空側)に突出しないように形成し、滑走対象物Wを容易に載置可能としている。また、ローラ78によって、滑走対象物Wに勢いを付与することができ、スムーズな滑走を可能にしている。
Further, as shown in FIG. 23 (b), the side wall 77 of the loading port shawl member 70C is formed in an inclined shape in a side view so as to become lower from the downstream side toward the upstream side.
Further, when the narrow downstream end portion 72 of the inlet shura member 70C is placed on the wide upstream end portion 71 of the taper type shura member 70B, the downstream side of the side wall 77 of the inlet shura member 70C is tapered. The shura member 70B is formed so as not to protrude upward (empty side) from the upstream side of the side wall 77 of the shura member 70B, so that the sliding object W can be easily placed. In addition, the roller 78 can give momentum to the sliding object W, thereby enabling smooth sliding.

When the narrow downstream end 72 of the upstream shura member 70 is placed and fitted into the wide upstream end 71 of the downstream shura member 70, both members are positioned relative to each other, although not shown. In order not to be displaced, a joint portion or a connecting member that can be detachably connected is provided.
The material of the shura member 70 is vinyl chloride, plastic, FRP, duralumin, stainless steel, iron or the like.
Further, the upstream end width dimension Xa of the branching shura member 70A and the taper type shura member 70B is made the same dimension, and the downstream end width dimension Xb of the branch shura member 70A, the taper type shura member 70B and the inlet shura member 70C is the same dimension.

次に、図25(d)に示すような滑道60を形成する場合を例に説明する。
図24及び図25に於て、形成すべき滑道60の中心線を滑道予定線90として一点鎖線で示す。滑道予定線90は、形成される滑道60の投入口部61が対応し滑道予定線90の上流端位置に配設される投入口予定部91と、形成される滑道60のカーブ部62と対応する湾曲滑道予定部92と、形成される滑道60の合流部63と対応し滑道予定線90の中間位置に配設される合流予定部93と、形成される滑道60のストレート部64と対応する直線滑道予定部94と、を有している。
Next, the case where the runway 60 as shown in FIG.25 (d) is formed is demonstrated to an example.
In FIG. 24 and FIG. 25, the center line of the runway 60 to be formed is shown as a runway planned line 90 by a one-dot chain line. The planned runway 90 corresponds to the input port 61 of the runway 60 to be formed, the planned entrance 91 located at the upstream end position of the planned runway 90, and the curve of the runway 60 to be formed. A curved runway planned portion 92 corresponding to the portion 62, a merged planned portion 93 corresponding to the merged portion 63 of the formed slide 60 and disposed at an intermediate position of the planned runway 90, and a formed slide 60 straight portions 64 and corresponding straight runway planned portions 94.

図24(a)に示すように、低位置Sに多数の修羅部材70、回転ドラム5、ウインチ6、駆動源E、操作部9、テンション用滑車3(3A)、折り返し用滑車3(3B)を、配設する。また、低位置Sから高位置Jにわたって、滑道予定線90の下流側から所定の中間位置の近傍に、複数の架設部30を設置する。修羅部材70が牽引される往路側が滑道予定線90に沿って接近するように架設部30を設けるのが望ましい。   As shown in FIG. 24 (a), a number of shura members 70, a rotating drum 5, a winch 6, a drive source E, an operation unit 9, a tension pulley 3 (3A), and a folding pulley 3 (3B) at a low position S. Is disposed. In addition, a plurality of erection parts 30 are installed in the vicinity of a predetermined intermediate position from the downstream side of the planned runway 90 from the low position S to the high position J. It is desirable to provide the erection part 30 so that the outward path to which the shura member 70 is pulled approaches along the planned runway 90.

図24(b)に示すように、回転ドラム5、ウインチ6、架設部30を介して搬送ロープ2を、低位置Sから高位置Jにわたって閉ループ状に懸架(張架)し、ウインチ6にて張りを付与し、回転ドラム5を水平軸心周りに回転駆動させ、搬送ロープ2を引込みつつ送り出して、閉ループ状の搬送ロープ2を周回駆動させる。図1及び図13に示すように修羅部材70と連結したフック部材79を搬送ロープ2の吊り輪状の引掛部21に順次係止させて、修羅部材70を牽引する。   As shown in FIG. 24 (b), the conveying rope 2 is suspended (stretched) in a closed loop shape from the low position S to the high position J via the rotating drum 5, the winch 6, and the erection part 30. The tension is applied, the rotary drum 5 is driven to rotate around the horizontal axis, the transport rope 2 is sent out while being pulled, and the closed-loop transport rope 2 is driven to rotate. As shown in FIGS. 1 and 13, the hook member 79 connected to the shawl member 70 is sequentially locked to the hanging ring-shaped hooking portion 21 of the transport rope 2, and the shawl member 70 is pulled.

図24(c)に示すように、直線滑道予定部94に複数のテーパ型修羅部材70Bを下流側から順次直線状に配設して連結し、滑道予定線90の中間位置にある合流予定部93に分岐修羅部材70Aを配設して連結する。この最も下流位置に形成される合流部63より下流側にあるストレート部64は、滑道60の完成後に各投入口部61から投入された滑走対象物Wが低位置S側の1箇所(集材所)に滑走対象物Wを導く主流部65である。   As shown in FIG. 24 (c), a plurality of taper type shura members 70B are arranged in a straight line from the downstream side and connected to the straight runway planned portion 94, and are joined at the intermediate position of the runway planned line 90. A branching shura member 70A is arranged and connected to the planned portion 93. The straight portion 64 on the downstream side of the joining portion 63 formed at the most downstream position has a sliding object W introduced from each inlet portion 61 after completion of the runway 60 at one location (collection point) on the low position S side. This is a mainstream portion 65 that guides the sliding object W to the lumber).

そして、図24(c)、図25(a)、図25(b)、図25(c)、図25(d)と順次示すように、分岐修羅部材70Aを配設した位置から枝分かれして上流側に延伸する滑道予定線90の近傍に新たな架設部30を順次設ける。
また、搬送ロープ2を、増設した架設部30に懸架可能に調節する。搬送ロープ2の連結部20の一方のロープ1Aの一端部11及び他方のロープ1Bの他端部13を長手方向に圧縮させ、各先端12,14を引き抜いて接続を解除する。そして、図24(b)から図24(c)そして図25(a)に示すように変更する場合は、クロスロープ1の本数を追加して順次連結部20を形成することで、所望長さに延長した搬送ロープ2を形成し閉ループ状に懸架させる。また、図25(b)から図25(c)そして図25(d)に示すように変更する場合は、クロスロープ1の本数を減少させて、搬送ロープ2を短縮させる。つまり、滑道予定線90に合わせて搬送ロープ2を延長又は短縮すると共に架設部30を増減させ、架設ルート(修羅部材70の搬送ルート)を順次変更させて、修羅部材70を搬送する。
24 (c), 25 (a), 25 (b), 25 (c), and 25 (d) are sequentially branched from the position where the branching shawl member 70A is disposed. New construction portions 30 are sequentially provided in the vicinity of the planned runway 90 extending upstream.
Moreover, the conveyance rope 2 is adjusted so that it can be suspended in the extended erection part 30. One end 11 of one rope 1A of the connecting portion 20 of the transport rope 2 and the other end 13 of the other rope 1B are compressed in the longitudinal direction, and the tips 12 and 14 are pulled out to release the connection. And when changing as shown in FIG.24 (b) from FIG.24 (c) and FIG.25 (a), by adding the number of the cross rope 1 and forming the connection part 20 one by one, desired length A transfer rope 2 extended to the above is formed and suspended in a closed loop. Further, in the case of changing from FIG. 25 (b) to FIG. 25 (c) and FIG. 25 (d), the number of the cross ropes 1 is decreased and the transport rope 2 is shortened. That is, the transfer rope 2 is extended or shortened in accordance with the planned runway 90, and the erection part 30 is increased or decreased, and the erection route (the conveyance route of the sura member 70) is sequentially changed to convey the sura member 70.

搬送した修羅部材70を、滑道60が下流側から上流側に向かって分岐し枝状に延伸するように順次配設して連結する。直線滑道予定部94にテーパ型修羅部材70Bを下流側から上流側に直線状に配設して連結する。また、合流予定部93に分岐修羅部材70Aを配設して分岐部(合流部63)を形成する。分岐部からさらに上流側に向かって、ストレート部64や別の合流部63を複数形成する。また、投入口予定部91に投入口用修羅部材70Cを配設して投入口部61を複数形成する。また湾曲滑道予定部92に複数のテーパ型修羅部材70Bを円弧状に配設して連結しカーブ部62を形成する。   The transported shura members 70 are sequentially arranged and connected so that the runway 60 branches from the downstream side toward the upstream side and extends in a branch shape. A taper type shura member 70B is linearly arranged from the downstream side to the upstream side and connected to the planned straight runway 94. Further, a branching shura member 70A is arranged in the planned joining portion 93 to form a branching portion (merging portion 63). A plurality of straight portions 64 and other merging portions 63 are formed from the branch portion toward the upstream side. In addition, a plurality of input port portions 61 are formed by disposing the input port scull member 70C in the planned input port portion 91. Further, a plurality of taper type shura members 70B are arranged in an arc shape and connected to the planned curved runway portion 92 to form a curved portion 62.

図19に示すように、修羅部材70同士の連結は、下流側の修羅部材70の幅広上流端部71に、上流側の修羅部材70の幅狭下流端部72を、載置して嵌め込む。また、湾曲滑道予定部92に於ては、下流側のテーパ型修羅部材70Bと上流側のテーパ型修羅部材70Bを平面視ヘの字状に連結し、複数のテーパ型修羅部材70Bで円弧状に連結しカーブ部62を形成する。   As shown in FIG. 19, the shawl members 70 are connected to each other by placing and fitting the narrow downstream end 72 of the upstream shura member 70 into the wide upstream end 71 of the downstream shura member 70. . Further, in the planned curved runway 92, the downstream taper-shaped shura member 70B and the upstream taper-shaped shura member 70B are connected in a U-shape in plan view, and a plurality of taper-shaped shura members 70B are used to form a circle. A curved portion 62 is formed by connecting in an arc.

また、修羅部材70の搬送開始位置側に、回転ドラム5やウインチ6、駆動源E、操作部9を配置し、架設ルートを変更する必要のある高位置J側には、搬送ロープ2を駆動させる機械やテンションを負荷する機械等を配設しないので、架設ルートの変更を容易にしている。また、架設部30は、滑車3を締結部材32で支柱部31に結束させるだけなので、取付・取り外し(増減)が容易に行われ、架設ルートが迅速に変更される。   Further, the rotating drum 5, the winch 6, the drive source E, and the operation unit 9 are arranged on the transfer start position side of the shura member 70, and the transfer rope 2 is driven on the high position J side where the installation route needs to be changed. The installation route is easily changed because no machine or a machine that applies tension is provided. Further, since the erection unit 30 only binds the pulley 3 to the support column 31 with the fastening member 32, attachment / removal (increase / decrease) is easily performed, and the erection route is quickly changed.

図25(d)及び図18に示すように、完成した滑道60は、合流部63やカーブ部62を有し、木々を避けるように枝状に配設される。そして、滑走対象物Wは高位置Jの様々な箇所から低位置S内1箇所の集材所に効率良く集められる。また、滑道60の使用後は、修羅部材70に分解し、滑道60の近傍に架設ルートを設けて、搬送ロープ2で牽引して搬出する。   As shown in FIG. 25 (d) and FIG. 18, the completed runway 60 has a merging portion 63 and a curved portion 62, and is arranged in a branch shape so as to avoid trees. Then, the sliding object W is efficiently collected from various places in the high position J to one collecting place in the low position S. Further, after the use of the runway 60, it is disassembled into the shura member 70, a construction route is provided in the vicinity of the runway 60, and it is pulled out by the transport rope 2 and carried out.

なお、本発明は設計変更可能であって、図7に於て、一方のロープ1Aの一端部11内に、挿入治具8と共に他方のロープ1Bの先端14を収納した後、挿入治具8のみを引き抜いて、他方のロープ1Bの先端14を、一方のロープ1Aの一端部11内に残存させて接続しても良い。なお、低位置Sとは搬送すべき修羅部材70が集積され搬送すべき場所より低い場所であれば良い。高位置Jとは搬送すべき修羅部材70が集積されている場所よりも高い場所である。   The design of the present invention can be changed. In FIG. 7, after inserting the insertion jig 8 and the tip 14 of the other rope 1B into the one end 11 of one rope 1A, the insertion jig 8 is inserted. Only the tip of the other rope 1B may be withdrawn, and the tip 14 of the other rope 1B may remain in the one end portion 11 of the one rope 1A. Note that the low position S may be any place that is lower than the place where the shura members 70 to be transported are stacked and transported. The high position J is a place higher than the place where the shura members 70 to be transported are accumulated.

以上のように、本発明の修羅設置方法は、2本の中空状のクロスロープ1A,1Bの内、一方のクロスロープ1Aの一端部11に他方のクロスロープ1Bの他端部13側の先端14を挿入し、かつ、他方のクロスロープ1Bの他端部13に一方のクロスロープ1Aの一端部11側の先端12を挿入して、接続・分離自在な連結部20を構成し、複数本のクロスロープ1A,1Bを順次連結部20にて接続して搬送ロープ2を形成し、搬送ロープ2を低位置Sから高位置Jにわたって閉ループ状に懸架して周回駆動させ、滑道60を形成するための修羅部材70を低位置Sから牽引して高位置Jまで搬送するように構成し、さらに、接続する複数本のクロスロープ1A,1Bの本数を増減させて、搬送ロープ2が懸架される架設ルートを順次変更させてゆくので、搬送ロープ2を現場にて容易に延長又は短縮できる。架設ルートを地形等の周囲の環境に柔軟に対応させて自由に変更できる。油圧カッター等の大型で駆動源が必要となるような切断機械や、連結用の接続金具が必要なく、複雑に編み込むアイスプライスを形成せずに、迅速かつ安価に搬送ロープ2を延長・短縮作業を行うことができる。人の手によって修羅部材70を搬送する必要がなく、修羅部材70をステンレス等の重い金属や様々な形状にしても容易かつ迅速に搬送できる。   As described above, the shura installation method of the present invention is such that, of the two hollow cross ropes 1A and 1B, one end 11 of one cross rope 1A is connected to the tip of the other cross rope 1B on the other end 13 side. 14 is inserted, and the tip 12 on the one end 11 side of one cross rope 1A is inserted into the other end 13 of the other cross rope 1B to form a connectable / separable connecting portion 20, and a plurality of The cross ropes 1A and 1B are sequentially connected at the connecting portion 20 to form the transport rope 2, and the transport rope 2 is suspended in a closed loop from the low position S to the high position J to form a runway 60. The shawl member 70 is pulled from the low position S and transported to the high position J, and the transport rope 2 is suspended by increasing or decreasing the number of cross ropes 1A and 1B to be connected. The construction route will be changed sequentially, so 2 can be easily extended or shortened on site. The erection route can be changed freely according to the surrounding environment such as terrain. No need for a cutting machine such as a hydraulic cutter that requires a drive source or connecting fittings for connection, and without requiring the formation of a complicated knitting ice price, the conveyor rope 2 can be extended and shortened quickly and inexpensively. It can be performed. It is not necessary to transport the shura member 70 by human hands, and the shura member 70 can be transported easily and quickly even if it is made of a heavy metal such as stainless steel or various shapes.

また、搬送ロープ2を、回転駆動する回転ドラム5に複数回巻設して、搬送ロープ2を引込みつつ送り出すようにして、低位置Sと高位置Jの間を周回駆動させるので、滑りを防止して回転ドラム5の回転力を確実に搬送ロープ2に伝達でき、エネルギー効率良く周回駆動させることができる。搬送ロープ2を閉ループ状に形成でき架設作業を容易に行うことができる。   In addition, the conveyance rope 2 is wound around the rotary drum 5 that is driven to rotate, and the conveyance rope 2 is pulled out and sent out to rotate between the low position S and the high position J, thereby preventing slippage. Thus, the rotational force of the rotary drum 5 can be reliably transmitted to the transport rope 2 and can be driven around in an energy efficient manner. The transport rope 2 can be formed in a closed loop shape, and the erection work can be easily performed.

また、修羅部材70の内、予めY字状に形成した合流部形成用の分岐修羅部材70Aを、滑道予定線90の中間位置に配設し、下流側から上流側に向かって分岐させて滑道60を枝状に延伸させてゆくので、枝状の滑道60を容易に形成できる。現場に存在する木々や石等の障害物を避けて滑道60を形成できる。複数箇所からの滑走対象物Wを1箇所に集積させるように滑走させることが可能な効率の良い滑道60を形成できる。   Further, a branching shroud member 70A for forming a joining portion, which is formed in a Y-shape in advance, is arranged at an intermediate position of the planned runway 90 and branched from the downstream side toward the upstream side. Since the runway 60 is extended into branches, the branch-like runway 60 can be easily formed. The runway 60 can be formed avoiding obstacles such as trees and stones existing on the site. It is possible to form an efficient runway 60 that can be slid so that the sliding objects W from a plurality of places are accumulated in one place.

また、上記修羅部材70の内、予め上流側拡幅状に形成したテーパ型修羅部材70Bを、湾曲滑道予定部92に複数配設し、下流側のテーパ型修羅部材70Bの幅広上流端部71に、上流側のテーパ型修羅部材70Bの幅狭下流端部72を、嵌め込み、滑道60にカーブ部62を形成するので、斜面に存在する木々や石等の障害物を避けて滑道60を形成できる。滑道60を周囲の地形等の環境に柔軟に対応させて形成できる。   In addition, a plurality of taper type shura members 70B formed in advance in the upstream widened shape among the above-mentioned shura members 70 are disposed in the curved runway planned portion 92, and the wide upstream end portion 71 of the taper type shura member 70B on the downstream side. In addition, the narrow downstream end portion 72 of the upstream taper type shura member 70B is fitted and the curved portion 62 is formed on the runway 60. Therefore, the runway 60 avoids obstacles such as trees and stones existing on the slope. Can be formed. The runway 60 can be formed flexibly corresponding to the environment such as the surrounding terrain.
