実施の形態１．
　図１は、エレベーターの構造の一例を示す模式図である。 Embodiment 1.
FIG. 1 is a schematic diagram showing an example of the structure of an elevator.
　図１は、ロープ式エレベーターの一例を示す。エレベーター１は、例えば、かご２、釣合おもり３、巻上ロープ４、巻上機５、及びそらせ車６を備える。巻上ロープ４は、巻上機５の綱車５ａ及びそらせ車６に巻き掛けられる。かご２及び釣合おもり３は、巻上ロープ４によって昇降路内に吊り下げられる。巻上ロープ４の両端は、例えば、楔式留め装置７を介してかご枠２ａ及び釣合おもり３に連結される。 Figure 1 shows an example of a rope elevator. The elevator 1 includes, for example, a car 2, a counterweight 3, a hoisting rope 4, a hoisting machine 5, and a deflector wheel 6. The hoisting rope 4 is wound around the sheave 5a and the deflecting wheel 6 of the hoisting machine 5. The car 2 and the counterweight 3 are suspended in the hoistway by a hoisting rope 4. Both ends of the hoisting rope 4 are connected to the car frame 2a and the counterweight 3 via a wedge type fastening device 7, for example.
　楔式留め装置７は、エレベーター１の索状体をかご枠２ａ、釣合おもり３又は昇降路内の梁などに連結するために用いられる。エレベーター１の索状体は、巻上ロープ４に限らず、例えば、補償ロープ及びベルト等を含む。 The wedge type fastening device 7 is used to connect the rope-like body of the elevator 1 to the car frame 2a, the counterweight 3 or the beam in the hoistway. The rope-shaped body of the elevator 1 includes not only the hoisting rope 4 but also, for example, a compensating rope and a belt.
　図２及び図３は、楔式留め装置の一例を示す図である。 2 and 3 are views showing an example of a wedge type fastening device.
　図２及び図３は、ワイヤーロープ用の楔式留め装置７に巻上ロープ４が取り付けられた状態を例示する。図３は、図２に示すものとは異なる形状の楔式留め装置７を示す。 2 and 3 illustrate a state in which the hoisting rope 4 is attached to the wedge type fastening device 7 for a wire rope. FIG. 3 shows a wedge-type fastening device 7 of a different shape than that shown in FIG.
　楔式留め装置７は、ロッド８、ソケット９、楔１０及びナット１１を備える。ロッド８には、ネジ部８ａが形成されている。ソケット９は、ロッド８の一端部に接続されている。ネジ部８ａは、例えば、ロッド８の他端部側の一定の範囲に形成されている。ネジ部８ａの長さは、楔式留め装置７の種類によって異なり得る。ネジ部８ａには、１つ又は複数のナット１１が取り付けられる。ナット１１は、締め付ける方向に回転されるとソケット９側に向かって移動する。ナット１１は、例えば、右ネジナットである。 The wedge type fastening device 7 includes a rod 8, a socket 9, a wedge 10 and a nut 11. The rod 8 is formed with a screw portion 8a. The socket 9 is connected to one end of the rod 8. The screw portion 8a is formed, for example, in a certain range on the other end side of the rod 8. The length of the screw portion 8a may vary depending on the type of the wedge type fastening device 7. One or a plurality of nuts 11 are attached to the screw portion 8a. The nut 11 moves toward the socket 9 side when rotated in the tightening direction. The nut 11 is, for example, a right-hand screw nut.
　巻上ロープ４は、ソケット９の先端から挿し込まれ、楔１０に巻き付けられた状態で折り返され、ソケット９の先端から引き出される。楔１０は、先端が露出するまでソケット９の中に引き込まれる。その後、楔１０の先端に形成された穴に抜け防止用の割りピン１０ａが取り付けられる。折り返されて２本並んだ巻上ロープ４は、ソケット９の先端付近において、ワイヤークリップ１２で固定される。このようにして、巻上ロープ４の端部が楔式留め装置７に取り付けられる。 The hoisting rope 4 is inserted from the tip of the socket 9, folded back around the wedge 10, and pulled out from the tip of the socket 9. The wedge 10 is pulled into the socket 9 until the tip is exposed. After that, the split pin 10a for preventing slipping out is attached to the hole formed at the tip of the wedge 10. The two hoisting ropes 4 that are folded back and lined up are fixed by a wire clip 12 near the tip of the socket 9. In this way, the end of the hoisting rope 4 is attached to the wedge type fastening device 7.

FIG. 5 is a side view of the cord attachment jig according to the first embodiment as viewed from the lateral direction. FIG. 6 is a side view of the cord attachment jig according to the first embodiment as viewed from the longitudinal direction.
　索状体取付治具１３は、エレベーター１の索状体を楔式留め装置７に取り付ける作業で用いられる。図４から図６は、ワイヤーロープ用の楔式留め装置７に対して用いられる索状体取付治具１３を例示する。 The cord attachment jig 13 is used for attaching the cord of the elevator 1 to the wedge type fastening device 7. 4 to 6 exemplify a cord attachment jig 13 used for the wedge type fastening device 7 for a wire rope.
　索状体取付治具１３は、ベース体１４を備える。ベース体１４は、例えば、ナット締込用フレーム１５及び索状体固定用フレーム１６を有する。ベース体１４には、受け部１７及び掴み部１８が設けられる。 The cord attachment jig 13 includes a base body 14. The base body 14 has, for example, a nut tightening frame 15 and a cord fixing frame 16. The base body 14 is provided with a receiving portion 17 and a grip portion 18.
　ナット締込用フレーム１５及び索状体固定用フレーム１６は、例えば、上方が開放された同様の形状を呈する。索状体固定用フレーム１６は、ナット締込用フレーム１５の内側に嵌め込むように配置される。索状体固定用フレーム１６は、ナット締込用フレーム１５に対して長手方向にスライド可能である。索状体固定用フレーム１６は、例えば、ナット締込用フレーム１５に対してボルト等で固定可能である。 The nut tightening frame 15 and the cord fixing frame 16 have, for example, the same shape with the upper part opened. The cord fixing frame 16 is arranged so as to be fitted inside the nut tightening frame 15. The cord fixing frame 16 is slidable in the longitudinal direction with respect to the nut tightening frame 15. The cord fixing frame 16 can be fixed to the nut tightening frame 15 with a bolt or the like, for example.
　受け部１７は、ナット締込用フレーム１５の長手方向における端部に設けられる。掴み部１８は、例えば、索状体固定用フレーム１６の長手方向における端部に設けられる。索状体固定用フレーム１６は、掴み部１８が設けられていない端部を受け部１７側に向けてナット締込用フレーム１５と組み合わせられる。ナット締込用フレーム１５と索状体固定用フレーム１６とが組み合わせられた状態において、受け部１７及び掴み部１８は、同一直線上に位置する。ベース体１４の長手方向における全長は、ナット締込用フレーム１５と索状体固定用フレーム１６とが組み合わせられた状態での受け部１７から掴み部１８までの長さに相当する。 The receiving portion 17 is provided at the end of the nut tightening frame 15 in the longitudinal direction. The grip portion 18 is provided, for example, at an end portion in the longitudinal direction of the cord fixing frame 16. The cord fixing frame 16 is combined with the nut tightening frame 15 toward the receiving portion 17 side, where the end portion where the grip portion 18 is not provided. When the nut tightening frame 15 and the cord fixing frame 16 are combined, the receiving portion 17 and the grip portion 18 are located on the same straight line. The entire length of the base body 14 in the longitudinal direction corresponds to the length from the receiving portion 17 to the grip portion 18 in a state in which the nut tightening frame 15 and the cord fixing frame 16 are combined.
　受け部１７は、例えば、ナット締込用フレーム１５の短手方向に沿って設けられる。受け部１７には、例えば、ナット締込用フレーム１５の長手方向から見てロッド８の径よりも大きく且つナット１１の外径よりも小さい溝又は穴が形成される。 The receiving portion 17 is provided, for example, along the lateral direction of the nut tightening frame 15. In the receiving portion 17, for example, a groove or a hole that is larger than the diameter of the rod 8 and smaller than the outer diameter of the nut 11 when viewed in the longitudinal direction of the nut tightening frame 15 is formed.
　掴み部１８は、例えば、上下に対向する２つのブロック部材を有する。索状体固定用フレーム１６の長手方向から見て、２つのブロック部材の互いに対向する面には、切欠き１８ａが形成されている。掴み部１８は、例えば、ナット締込用フレーム１５及び索状体固定用フレーム１６に対して着脱可能である。 The grip portion 18 has, for example, two block members facing each other vertically. A notch 18a is formed on the surfaces of the two block members facing each other when viewed in the longitudinal direction of the cord fixing frame 16. The grip 18 is attachable to and detachable from the nut tightening frame 15 and the cord fixing frame 16, for example.
　ブロック部材は、例えば、硬鋼線材で形成されるワイヤーロープよりも軟らかい材質で形成される。ブロック部材の材質としては、例えば、通常の鋼材、鋳物材、アルミニウム、合成樹脂又はゴム等を用いることが可能である。 The block member is made of a material softer than the wire rope made of hard steel wire, for example. As the material of the block member, for example, an ordinary steel material, cast material, aluminum, synthetic resin, rubber or the like can be used.
　ベース体１４は、底部１４ａ、奥側壁部１４ｂ及び手前側壁部１４ｃを有する。奥側壁部１４ｂは、例えば、受け部１７を右向きにした状態で底部１４ａの奥側端部から上方に突出するように形成されている。手前側壁部１４ｃは、例えば、受け部１７を右向きにした状態で底部１４ａの手前側端部から上方に突出するように形成されている。ナット締込用フレーム１５及び索状体固定用フレーム１６は、互いの底部１４ａ同士、奥側壁部１４ｂ同士及び手前側壁部１４ｃ同士が重なるように組み合わせられる。 The base body 14 has a bottom portion 14a, a back side wall portion 14b, and a front side wall portion 14c. The back side wall portion 14b is formed, for example, so as to project upward from the back side end portion of the bottom portion 14a with the receiving portion 17 facing right. The front side wall portion 14c is formed, for example, so as to project upward from the front end portion of the bottom portion 14a with the receiving portion 17 facing right. The nut tightening frame 15 and the cord-like body fixing frame 16 are combined so that the bottom portions 14a thereof, the rear side wall portions 14b, and the front side wall portion 14c overlap each other.
　底部１４ａは、例えば、短手方向における幅がソケット９の厚さに対応した大きさに形成されている。手前側壁部１４ｃは、奥側壁部１４ｂよりも低く形成されている。手前側壁部１４ｃの高さは、例えば、奥側壁部１４ｂの高さの半分である。手前側壁部１４ｃの高さは、例えば、掴み部１８の下側のブロック部材の高さと同等である。 The bottom portion 14a is formed such that the width in the lateral direction corresponds to the thickness of the socket 9. The front side wall portion 14c is formed lower than the back side wall portion 14b. The height of the front side wall portion 14c is, for example, half the height of the back side wall portion 14b. The height of the front side wall portion 14c is, for example, equal to the height of the block member below the grip portion 18.
　図７は、実施の形態１における索状体取付治具の使用時の状態を示す上面図である。図８は、実施の形態１における索状体取付治具の使用時の状態を短手方向から見た側面図である。図９は、実施の形態１における索状体取付治具の使用時の状態を長手方向から見た側面図である。 FIG. 7 is a top view showing a state of using the cord-like body mounting jig in the first embodiment. FIG. 8 is a side view of the cord-attaching jig according to the first embodiment when it is used, as viewed from the lateral direction. FIG. 9 is a side view of the cord-attaching jig according to the first embodiment when it is used, as viewed from the longitudinal direction.
　図７から図９は、ワイヤーロープ用の楔式留め装置７に対して用いられる索状体取付治具１３の使用時の状態を例示する。 7 to 9 exemplify a state of using the cord attachment jig 13 used for the wedge type fastening device 7 for a wire rope.
　索状体取付治具１３は、例えば、ベース体１４の長手方向における全長が楔式留め装置７の長手方向における全長よりも長い状態で使用される。ベース体１４の全長は、索状体固定用フレーム１６をナット締込用フレーム１５に対してスライドさせることで調整可能である。楔式留め装置７の全長は、ロッド８のネジ部８ａが形成された側の端部からソケット９の先端までの長さに相当する。 The cord attachment jig 13 is used, for example, in a state where the entire length of the base body 14 in the longitudinal direction is longer than the entire length of the wedge type fastening device 7 in the longitudinal direction. The total length of the base body 14 can be adjusted by sliding the cord fixing frame 16 with respect to the nut tightening frame 15. The entire length of the wedge type fastening device 7 corresponds to the length from the end of the rod 8 on the side where the threaded portion 8a is formed to the tip of the socket 9.
　楔式留め装置７は、ソケット９の先端を掴み部１８側に向けて、ベース体１４の内側に配置される。ソケット９に通されて楔１０に巻き付けられた巻上ロープ４は、掴み部１８の２つの切欠き１８ａで挟み込まれることで把持される。ロッド８は、ネジ部８ａの一部のみが索状体取付治具１３の外側に突き出す状態で受け部１７に支持される。ナット１１は、ネジ部８ａのうち索状体取付治具１３の外側に突き出した部分に取り付けられる。 The wedge type fastening device 7 is arranged inside the base body 14 with the tip of the socket 9 facing the grip portion 18 side. The hoisting rope 4 passed through the socket 9 and wound around the wedge 10 is gripped by being sandwiched by the two notches 18 a of the grip portion 18. The rod 8 is supported by the receiving portion 17 in a state where only a part of the screw portion 8 a projects to the outside of the cord-shaped body attachment jig 13. The nut 11 is attached to a portion of the threaded portion 8a that protrudes to the outside of the cord-shaped body attachment jig 13.
　受け部１７には、例えば、摩擦低減部材１９が設けられる。摩擦低減部材１９は、例えば、スラストベアリング又はドライベアリング等である。摩擦低減部材１９は、例えば、摩擦係数の低いコーティングであってもよい。 The receiving portion 17 is provided with a friction reducing member 19, for example. The friction reducing member 19 is, for example, a thrust bearing or a dry bearing. The friction reducing member 19 may be, for example, a coating having a low coefficient of friction.
　図１０から図１４は、実施の形態１における索状体取付治具を用いた取付作業の手順を説明するための図である。 10 to 14 are diagrams for explaining the procedure of the attachment work using the cord attachment jig in the first embodiment.
　以下、図１０から図１４を参照して、楔式留め装置７への巻上ロープ４の取付作業を説明する。 Hereinafter, the work of attaching the hoisting rope 4 to the wedge type fastening device 7 will be described with reference to FIGS. 10 to 14.
　まず、図１０に示すように、巻上ロープ４がソケット９に通される。この時点では、楔１０は、ソケット９の中に十分に引き込まれなくともよい。折り返されて２本並んだ巻上ロープ４のうち、下側の一方は荷重側ロープ４ａである。折り返されて２本並んだ巻上ロープ４のうち、上側の他方は非荷重側ロープ４ｂである。 First, as shown in FIG. 10, the hoisting rope 4 is passed through the socket 9. At this point, the wedge 10 may not be fully retracted into the socket 9. Of the two hoisting ropes 4 folded back and lined up, one on the lower side is the load side rope 4a. Of the two hoisting ropes 4 folded back and lined up, the other one on the upper side is the non-load side rope 4b.
　次に、図１１に示す位置関係となるように、楔式留め装置７の位置及びベース体１４の全長が調整される。楔式留め装置７は、例えば、ロッド８がベース体１４の外側に５０ｍｍから１００ｍｍ程度突き出すように配置される。ベース体１４の全長は、荷重側ロープ４ａを掴み部１８で把持できるように調整される。掴み部１８は、例えば、非荷重側ロープ４ｂに接触しないように配置される。 Next, the position of the wedge type fastening device 7 and the total length of the base body 14 are adjusted so that the positional relationship shown in FIG. 11 is obtained. The wedge type fastening device 7 is arranged, for example, such that the rod 8 projects to the outside of the base body 14 by about 50 mm to 100 mm. The entire length of the base body 14 is adjusted so that the load side rope 4a can be gripped by the grip portion 18. The grip portion 18 is arranged, for example, so as not to contact the rope 4b on the non-load side.
　なお、楔式留め装置７の全長がナット締込用フレーム１５よりも短い場合は、ナット締込用フレーム１５に掴み部１８が取り付けられてもよい。この場合、索状体固定用フレーム１６は使用されなくともよい。 If the overall length of the wedge type fastening device 7 is shorter than the nut tightening frame 15, the gripping part 18 may be attached to the nut tightening frame 15. In this case, the cord fixing frame 16 may not be used.
　次に、図１２に示すように、荷重側ロープ４ａが掴み部１８で把持される。掴み部１８の２つのブロック部材は、例えば、底部１４ａの裏側からベース体１４の内側へ立ち上げられた複数のボルトによってベース体１４に取り付けられる。荷重側ロープ４ａは、例えば、上側のブロック部材の上方から当該ボルトに取り付けられたナットが締め付けられることで、２つのブロック部材によって挟み込まれる。 Next, as shown in FIG. 12, the load-side rope 4a is gripped by the grip portion 18. The two block members of the grip portion 18 are attached to the base body 14 by, for example, a plurality of bolts raised from the back side of the bottom portion 14a to the inside of the base body 14. The load-side rope 4a is sandwiched between two block members, for example, by tightening a nut attached to the bolt from above the upper block member.
　次に、図１３に示すように、受け部１７の溝又は穴でロッド８が支持される。例えば、摩擦低減部材１９としてベアリングが用いられる場合には、ベアリング、平座２０及びナット１１が順番にロッド８のネジ部８ａに取り付けられる。ベアリングは、受け部１７で支持される。平座２０及びナット１１は、ナット締込用フレーム１５の外側に配置される。平座２０及びナット１１は、例えば、楔式留め装置７が元から備える部品である。 Next, as shown in FIG. 13, the rod 8 is supported by the groove or hole of the receiving portion 17. For example, when a bearing is used as the friction reducing member 19, the bearing, the flat seat 20, and the nut 11 are sequentially attached to the threaded portion 8 a of the rod 8. The bearing is supported by the receiving portion 17. The flat seat 20 and the nut 11 are arranged outside the nut tightening frame 15. The flat seat 20 and the nut 11 are parts originally included in the wedge type fastening device 7, for example.
　次に、図１３の矢印が示すように、締め付ける方向にナット１１が回転される。図１３は、ナット１１が右ネジナットである場合を例示する。受け部１７は、ナット１１がロッド８に対して回転することでソケット９側に向かって移動する力を受ける。ナット１１が回転すると、ロッド８及びソケット９が掴み部１８側から受け部１７側に向かって移動する。ロッド８及びソケット９が移動する力により、相対的に、楔１０がソケット９の中に引き込まれる。 Next, as shown by the arrow in Fig. 13, the nut 11 is rotated in the tightening direction. FIG. 13 illustrates a case where the nut 11 is a right-handed screw nut. The receiving portion 17 receives a force that moves toward the socket 9 side as the nut 11 rotates with respect to the rod 8. When the nut 11 rotates, the rod 8 and the socket 9 move from the grip portion 18 side toward the receiving portion 17 side. The force of movement of the rod 8 and the socket 9 relatively draws the wedge 10 into the socket 9.
　ナット１１の回転に伴ってロッド８及びソケット９が回転しようとする力は、ソケット９がベース体１４の奥側壁部１４ｂに当たることで受けられる。つまり、ナット１１が回転する際に楔式留め装置７がベース体１４の内側で空回りすることはない。 The force that the rod 8 and the socket 9 try to rotate with the rotation of the nut 11 is received by the socket 9 hitting the inner side wall portion 14 b of the base body 14. That is, when the nut 11 rotates, the wedge type fastening device 7 does not idle inside the base body 14.
　ナット１１の回転は、図１４に示すように、楔１０の先端に形成された穴１０ｂがソケット９の先端から露出するまで継続される。その後、楔１０の穴１０ｂに割りピン１０ａが取り付けられることで、楔式留め装置７への巻上ロープ４の取付作業が完了する。 The rotation of the nut 11 is continued until the hole 10b formed at the tip of the wedge 10 is exposed from the tip of the socket 9, as shown in FIG. After that, the split pin 10a is attached to the hole 10b of the wedge 10, whereby the work of attaching the hoisting rope 4 to the wedge type fastening device 7 is completed.
　なお、索状体取付治具１３の使用時において、ベース体１４の長手方向における全長は、必ずしも楔式留め装置７の長手方向における全長よりも長い必要はない。例えば、ロッド８の全体にネジ部８ａが形成されている場合は、ロッド８の大部分がベース体１４の外側に突き出す状態で、受け部１７付近にソケット９が位置するように楔式留め装置７が配置されたとしても、ナット１１を回転させることで楔１０をソケット９の中に引き込むことが可能である。この場合、ベース体１４の全長は、少なくともソケット９の全長よりは長い必要があるが、楔式留め装置７の全長よりも短くてもよい。ベース体１４の全長は、荷重側ロープ４ａが掴み部１８で把持された状態でネジ部８ａが受け部１７上に位置することが可能な長さであればよい。ベース体１４の全長は、例えば、楔式留め装置７のソケット９の先端からネジ部８ａのソケット９側の端部までの長さよりも長く設定される。 Note that, when using the cord attachment jig 13, the total length of the base body 14 in the longitudinal direction does not necessarily need to be longer than the total length of the wedge type fastening device 7 in the longitudinal direction. For example, when the threaded portion 8a is formed on the entire rod 8, the wedge-type fastening device is arranged so that the socket 9 is located near the receiving portion 17 with most of the rod 8 protruding outside the base body 14. Even if 7 is arranged, it is possible to pull the wedge 10 into the socket 9 by rotating the nut 11. In this case, the total length of the base body 14 needs to be at least longer than the total length of the socket 9, but may be shorter than the total length of the wedge type fastening device 7. The entire length of the base body 14 may be a length that allows the screw portion 8a to be positioned on the receiving portion 17 in a state where the load side rope 4a is gripped by the grip portion 18. The total length of the base body 14 is set to be longer than, for example, the length from the tip of the socket 9 of the wedge type fastening device 7 to the end of the screw portion 8a on the socket 9 side.

FIG. 16 is a cross-sectional view showing a second example of the grip portion of the cord attachment jig in the first embodiment. FIG. 17 is a cross-sectional view showing a third example of the grip portion of the cord attachment jig in the first embodiment.
　図１５から図１７は、ワイヤーロープ用の楔式留め装置７に対して用いられる索状体取付治具１３の掴み部１８を例示する。 15 to 17 exemplify the grip portion 18 of the cord attachment jig 13 used for the wedge type fastening device 7 for a wire rope.
　図１５に示す掴み部１８の第１例では、断面が半円形の切欠き１８ａがブロック部材に形成されている。この場合、巻上ロープ４は、切欠き１８ａの曲面で押さえつけられることで把持される。 In the first example of the grip portion 18 shown in FIG. 15, a notch 18a having a semicircular cross section is formed in the block member. In this case, the hoisting rope 4 is gripped by being pressed by the curved surface of the notch 18a.
　図１６に示す掴み部１８の第２例では、断面がＶ字形の切欠き１８ａがブロック部材に形成されている。この場合、巻上ロープ４は、切欠き１８ａの平面で４方向から押さえつけられることで把持される。 In the second example of the grip portion 18 shown in FIG. 16, a notch 18a having a V-shaped cross section is formed in the block member. In this case, the hoisting rope 4 is grasped by being pressed from the four directions by the plane of the notch 18a.
　図１７に示す掴み部１８の第３例では、断面が台形の切欠き１８ａがブロック部材に形成されている。この場合、巻上ロープ４は、切欠き１８ａの平面で６方向から押さえつけられることで把持される。 In the third example of the grip portion 18 shown in FIG. 17, a notch 18a having a trapezoidal cross section is formed in the block member. In this case, the hoisting rope 4 is gripped by being pressed from the six directions by the plane of the notch 18a.
　以上で説明した実施の形態１によれば、楔式留め装置７への索状体取付治具１３は、ベース体１４、掴み部１８及び受け部１７を備える。ベース体１４は、例えば、楔式留め装置７のソケット９の全長よりも長手方向における全長が大きい。ベース体１４の全長は、例えば、楔式留め装置７のソケット９の先端からロッド８に形成されたネジ部８ａのソケット９側の端部までの長さよりも大きい。掴み部１８は、ベース体１４の長手方向における一端部に設けられ、楔式留め装置７のソケット９に通されたエレベーター１の索状体を固定可能である。受け部１７は、ベース体１４の長手方向における他端部に設けられ、楔式留め装置７のロッド８のネジ部８ａに取り付けられたナット１１が回転することでソケット９側に向かって移動する力を受ける。つまり、索状体取付治具１３を用いれば、楔式留め装置７の一部であるネジ部８ａ及びナット１１を利用して、索状体に大きな引っ張り荷重を付加することができる。このため、簡単な構成で、エレベーター１の索状体が巻き付けられた楔１０を容易にソケット９の中に引き込むことができる。 According to the first embodiment described above, the cord attachment jig 13 for the wedge type fastening device 7 includes the base body 14, the grip portion 18, and the receiving portion 17. The base body 14 has a total length in the longitudinal direction larger than the total length of the socket 9 of the wedge type fastening device 7, for example. The total length of the base body 14 is, for example, larger than the length from the tip of the socket 9 of the wedge type fastening device 7 to the end of the threaded portion 8a formed on the rod 8 on the socket 9 side. The grip portion 18 is provided at one end portion in the longitudinal direction of the base body 14 and can fix the cord-shaped body of the elevator 1 which is passed through the socket 9 of the wedge type fastening device 7. The receiving portion 17 is provided at the other end portion in the longitudinal direction of the base body 14 and moves toward the socket 9 side by rotation of the nut 11 attached to the screw portion 8a of the rod 8 of the wedge type fastening device 7. Receive power. That is, if the cord-shaped body attachment jig 13 is used, a large tensile load can be applied to the cord-shaped body by using the screw portion 8a and the nut 11 which are a part of the wedge type fastening device 7. Therefore, the wedge 10 around which the cord of the elevator 1 is wound can be easily pulled into the socket 9 with a simple configuration.
　また、例えば、受け部１７には、摩擦低減部材１９が設けられる。この場合、ナット１１が滑らかに回転するため、より小さい力で楔式留め装置７への索状体の取付作業を行うことができる。 Further, for example, the receiving portion 17 is provided with a friction reducing member 19. In this case, since the nut 11 rotates smoothly, the work of attaching the cord to the wedge type fastening device 7 can be performed with a smaller force.
　また、例えば、ベース体１４は、受け部１７が設けられたナット締込用フレーム１５及び掴み部１８が設けられた索状体固定用フレーム１６を有する。索状体固定用フレーム１６は、ナット締込用フレーム１５に対して長手方向にスライド可能である。この場合、１つの索状体取付治具１３で様々な長さの楔式留め装置７に対応可能となる。 Further, for example, the base body 14 has a nut tightening frame 15 provided with a receiving portion 17 and a cord fixing frame 16 provided with a grip portion 18. The cord fixing frame 16 is slidable in the longitudinal direction with respect to the nut tightening frame 15. In this case, one cord attachment jig 13 can be used for the wedge type fastening devices 7 of various lengths.
　また、例えば、ベース体１４は、底部１４ａ、奥側壁部１４ｂ及び手前側壁部１４ｃを有する。奥側壁部１４ｂは、例えば、受け部１７を右向きにした状態で底部１４ａの奥側から上方に突出する。手前側壁部１４ｃは、例えば、受け部１７を右向きにした状態で底部１４ａの手前側から上方に突出し、奥側壁部１４ｂよりも低い。この場合、ナット１１が回転する際に楔式留め装置７がベース体１４の内側で空回りすることを防止できる。また、手前側壁部１４ｃが低いため、ナット１１を回転させている際に、楔１０の穴１０ｂがソケット９の先端から露出したか否かを容易に視認できる。 Further, for example, the base body 14 has a bottom portion 14a, a back side wall portion 14b, and a front side wall portion 14c. The back side wall portion 14b projects upward from the back side of the bottom portion 14a with the receiving portion 17 facing right, for example. The front side wall portion 14c protrudes upward from the front side of the bottom portion 14a with the receiving portion 17 facing right, and is lower than the back side wall portion 14b. In this case, it is possible to prevent the wedge type fastening device 7 from idling inside the base body 14 when the nut 11 rotates. Further, since the front side wall portion 14c is low, it can be easily visually recognized whether the hole 10b of the wedge 10 is exposed from the tip of the socket 9 while the nut 11 is rotated.
　なお、ナット１１が左ネジナットである場合には、左右反転した形状の索状体取付治具１３を用いれば、奥側壁部１４ｂ及び手前側壁部１４ｃによる効果が得られる。この場合、奥側壁部１４ｂは、受け部１７を左向きにした状態で底部１４ａの奥側から上方に突出する。この場合、手前側壁部１４ｃは、受け部１７を左向きにした状態で底部１４ａの手前側から上方に突出し、奥側壁部１４ｂよりも低い。 If the nut 11 is a left-handed screw nut, the effect of the back side wall portion 14b and the front side wall portion 14c can be obtained by using the cord-shaped body attachment jig 13 having a horizontally inverted shape. In this case, the back side wall portion 14b projects upward from the back side of the bottom portion 14a with the receiving portion 17 facing left. In this case, the front side wall portion 14c protrudes upward from the front side of the bottom portion 14a with the receiving portion 17 facing left and is lower than the back side wall portion 14b.
　また、例えば、掴み部１８は、ベース体１４に対して着脱可能である。このため、索状体の太さ又は形状に応じて掴み部１８を使い分けることが可能となる。 Further, for example, the grip portion 18 can be attached to and detached from the base body 14. Therefore, it is possible to properly use the grip portion 18 according to the thickness or shape of the cord.
　また、例えば、掴み部１８は、断面が半円形の切欠き１８ａが形成された２つの部材で挟み込むことで索状体を把持する。この場合、曲面からワイヤーロープの中心に向かって力が加わるため、ワイヤーロープを変形させることなく把持力が得られる。 Further, for example, the grip portion 18 grips the cord-shaped body by sandwiching the grip portion 18 with two members each having a notch 18a having a semicircular cross section. In this case, since a force is applied from the curved surface toward the center of the wire rope, a gripping force can be obtained without deforming the wire rope.
　また、例えば、掴み部１８は、断面がＶ字形の切欠き１８ａが形成された２つの部材で挟み込むことで索状体を把持する。この場合、４面からワイヤーロープの中心に向かって力が加わるため、ワイヤーロープの変形を抑制しつつ把持力が得られる。また、平面でワイヤーロープを押さえるため、複数の太さのワイヤーロープに対応可能である。 Further, for example, the grasping portion 18 grasps the cord-like body by sandwiching the grasping portion 18 with two members in which a notch 18a having a V-shaped cross section is formed. In this case, since a force is applied from the four surfaces toward the center of the wire rope, the gripping force can be obtained while suppressing the deformation of the wire rope. Also, since the wire rope is pressed down on a flat surface, it is possible to handle wire ropes of different thicknesses.
　また、例えば、掴み部１８は、断面が台形の切欠き１８ａが形成された２つの部材で挟み込むことで索状体を把持する。この場合、６面からワイヤーロープの中心に向かって力が加わるため、ワイヤーロープの変形を抑制しつつ把持力が得られる。また、平面でワイヤーロープを押さえるため、複数の太さのワイヤーロープに対応可能である。 Further, for example, the grasping portion 18 grasps the cord-like body by sandwiching the grasping portion 18 with two members each having a notch 18a having a trapezoidal cross section. In this case, a force is applied from the six faces toward the center of the wire rope, so that the gripping force can be obtained while suppressing the deformation of the wire rope. Also, since the wire rope is pressed down on a flat surface, it is possible to handle wire ropes of different thicknesses.
　実施の形態１における索状体取付治具１３は、掴み部１８を変更すれば、ベルト用の楔式留め装置７に対して用いることが可能である。この場合、例えば、断面が長方形の切欠き１８ａが形成された掴み部１８をベース体１４に取り付ければよい。 The cord attachment jig 13 in the first embodiment can be used for the wedge type fastening device 7 for the belt by changing the grip portion 18. In this case, for example, the grip portion 18 in which the notch 18a having a rectangular cross section is formed may be attached to the base body 14.
　以上のように、この発明に係る楔式留め装置への索状体取付治具は、エレベーターの索状体を楔式留め装置に取り付ける作業に利用できる。 As described above, the cord attachment jig for the wedge type fastening device according to the present invention can be used for the work of attaching the rope type body of the elevator to the wedge type fastening device.
