[0080] like Figure 1 As shown, the tensioner support device 1 in the first embodiment includes a first rod 2, a second rod 3 and a spacing change device 4. The first rod 2 and the second rod 3 can each be composed of one part or a combination of multiple parts. The spacing change device 4 is composed of a combination of multiple parts.

[0081] like Figure 1 As shown, the first rod 2 has a first tensioner 110 (see Figure 5 ) is connected to a first front end portion 21 and a first base end portion 23.

[0082] like Figure 1 As shown, the second rod 3 has a second tensioner 120 (see Figure 5 ) is connected to a second front end portion 31 and a second base end portion 33.

[0083] The interval changing device 4 has a first connection part 41c, a second connection part 43c and an operating component 45, wherein the first connection part 41c is connected to the first base end part 23 of the first rod 2, the second connection part 43c is connected to the second base end part 33 of the second rod 3, and the operating component 45 changes the interval between the first connection part 41c and the second connection part 43c.

[0084] exist Figure 2In the example described, when the operating member 45 is operated in the first operating direction MR1, the distance between the first connection portion 41c and the second connection portion 43c decreases. On the other hand, when the operating member 45 is operated in the second operating direction MR2, the distance between the first connection portion 41c and the second connection portion 43c increases.

[0085] The first rod 2 is connected to the interval changing device 4 so as to be tiltable relative to the interval changing device 4 (see Fig.21 and Fig. 22 In addition, the second rod 3 is connected to the interval changing device 4 in a manner that it can be tilted relative to the interval changing device 4 (see Fig.21 and Fig. 22 Arrow AR4).

[0086] Next, the wire cutting tool 100 in the first embodiment will be described. Figure 5 As shown, the wire cutting tool 100 includes a first wire tensioner 110 and a second wire tensioner 120 in addition to the wire tensioner support device 1 .

[0087] The first tensioner 110 is connected to the first front end 21 of the first rod 2 so as to be swingable relative to the first rod 2. The second tensioner 120 is connected to the second front end 31 of the second rod 3 so as to be swingable relative to the second rod 3.

[0088] In the first embodiment, the first rod 2 and the second rod 3 can be tilted relative to the interval changing device 4. In addition, the interval between the first connecting portion 41c and the second connecting portion 43c can be changed to reduce the interval between the first rod 2 and the second rod 3. As a result, the wire cutting tool can be used to easily perform the wire cutting operation. More specifically, Fig.19 and Fig. 20 As shown in the example, the first tensioner 110 and the second tensioner 120 can be easily brought close to the wire W. In addition, by moving the interval changing device 4 upward, the first rod 2 and the second rod 3 can be tilted relative to the interval changing device 4 (see Figure 21 to Figure 23 ). By this tilting, the interval between the first tensioner 110 and the second tensioner 120 is expanded, and a wire W of a sufficient length can be arranged between the first tensioner 110 and the second tensioner 120 (refer to Fig.23 ). In addition, by operating the operating member 45 in the first operating direction MR1, the interval between the first connecting portion 41c and the second connecting portion 43c can be reduced (refer to Fig.26The distance between the first connecting portion 41c and the second connecting portion 43c is reduced, that is, the distance between the first tensioner 110 and the second tensioner 120 can be reduced. As a result, the wire W can be effectively relaxed in the area between the first tensioner 110 and the second tensioner 120 (in other words, the relaxation of the wire W can be ensured). By cutting the relaxed wire W, the wire W can be easily cut (refer to Fig. 27 ).

[0089] In the description of this specification, the wire material W is, for example, an electric wire (more specifically, an overhead wire).

[0090] Next, refer to Figures 1 to 33 , describing any additional structures that may be used in the wire tensioner support device 1 of the first embodiment and the wire cutting tool of the first embodiment.

[0091] (Changes in the positions of the first baton 2 and the second baton 3)

[0092] exist Figure 3 In the example described, the first rod 2 can be in the first horizontal position (refer to Figure 3 ) and the first standing posture (refer to Figure 3 The first horizontal posture is a posture along the first straight line SL connecting the first connecting portion 41c and the second connecting portion 43c, and the first standing posture is a posture standing from the first straight line SL. In addition, the second rod 3 can change its posture in the second horizontal posture (refer to Figure 3 The second standing posture (see the figure on the upper side) and the second standing posture (see Figure 3 The second lying posture is a posture along the first straight line SL, and the second standing posture is a posture standing up from the first straight line SL.

[0093] exist Fig.19 In the example described, when the first rod 2 and the second rod are in the standing position, the first tensioner 110 and the second tensioner 120 can be easily brought close to the wire W. In addition, by changing the first rod 2 and the second rod from the standing position to the lying position, a sufficient length of wire W can be arranged between the first tensioner 110 and the second tensioner 120 (see Fig.23 ).

[0094] exist Figure 4 In the example described, the first rod 2 and the second rod 3 are tilted relative to the interval changing device 4 (see arrow AR1), thereby the first rod 2, the interval changing device 4 and the second rod 3 can be arranged in a U shape (see Figure 4More specifically, the first rod 2, the interval changing device 4, and the second rod 3 may be arranged in a U-shape, so that the first rod 2 constitutes a first side portion of the U-shape, the interval changing device 4 constitutes a bottom portion of the U-shape, and the second rod 3 constitutes a second side portion of the U-shape.

[0095] The first rod 2, the interval changing device 4 and the third rod 3 can be arranged in a U shape, so that the first tensioner 110 and the second tensioner 120 can be easily approached to the wire W (see Fig.19 ).exist Fig.19 In the example described, since the direction of the gravity acting on the first tensioner 110 is roughly the same as the extension direction of the first rod 2, the operator can easily support the first tensioner 110 via the first rod 2. In addition, since the direction of the gravity acting on the second tensioner 120 is roughly the same as the extension direction of the second rod 3, the operator can easily support the second tensioner 120 via the second rod 3. Fig.19 In the described example, since the distance between the first tensioner 110 and the second tensioner 120 is short, the operator can easily perform the operation of hooking the first tensioner 110 and the second tensioner 120 on the wire W.

[0096] In addition, Fig. 20 In the example described, the separation distance between the first tensioner 110 hooked on the wire W and one of the operator's hands can be fully ensured by the first rod 2. In addition, the separation distance between the second tensioner 120 hooked on the wire W and the other hand of the operator can be fully ensured by the second rod 3. Thus, the operation of hooking the first tensioner 110 and the second tensioner 120 on the wire W (more specifically, the overhead wire) can be safely implemented without using a remote operation tool. In other words, the function of the remote operation rod (more specifically, an electrically insulating remote operation rod) used when hooking the first tensioner and the second tensioner on the wire W can be performed by the first rod 2 and the second rod 3.

[0097] For example, in Fig. 20 In the described example, the operator can hook the first tensioner 110 and the second tensioner 120 on the wire W respectively while holding the first base end 23 of the first rod 2 and the second base end 33 of the second rod 3 .

[0098] For example, in Fig. 20In the example described, the operator can operate two rods (i.e., the first rod 2 and the second rod 3) to replace one remote control rod, and respectively hook the first tensioner 110 and the second tensioner 120 on the wire W. Therefore, the operator can more easily perform the operation of respectively hooking the first tensioner 110 and the second tensioner 120 on the wire W. In addition, in the first embodiment, the use of the remote control rod T1 is not excluded. For example, Figure 7 As illustrated, the remote control rod T1 may be used to respectively hook the first tensioner 110 and the second tensioner 120 onto the wire W.

[0099] exist Figure 4 In the example described above, the first rod 2 and the second rod 3 are tilted relative to the interval changing device 4 (see arrow AR2), so that the first rod 2, the interval changing device 4 and the second rod 3 can be arranged in a straight line (see Figure 4 ). Fig.23 In the described example, the shape of the tensioner support device 1 (more specifically, the first rod 2, the interval changing device 4 and the second rod 3) is switched from a U-shape to a straight shape, thereby allowing a sufficient length of wire W to be arranged between the first tensioner 110 and the second tensioner 120.

[0100] exist Figure 4 In the example described, the first rod 2 and the second rod 3 are tilted relative to the interval changing device 4 (see arrow AR1), thereby enabling the first rod 2 and the second rod 3 to be arranged in parallel (see Figure 4 The first rod 2 and the second rod 3 are arranged in parallel, so that the tensioner support device 1 can be compactly folded. Therefore, the tensioner support device 1 (or the wire cutting tool 100 including the tensioner support device 1) can be easily transported using a vehicle or the like.

[0101] exist Figure 4 In the described example, when the maximum value of the distance between the first front end 21 of the first rod 2 and the second front end 31 of the second rod 3 (more specifically, the distance between the first front end 21 and the second front end 31 when the interval change device 4 is extended to the maximum and the first rod 2, the interval change device 4 and the second rod 3 are arranged in a straight line) is defined as the first value L1, the tensioner support device 1 can be folded so that the total length L2 of the tensioner support device 1 is less than 2 / 3 of the first value L1, less than 3 / 5 of the first value L1, or less than 1 / 2 of the first value L1. More specifically, when the first rod 2 and the second rod 3 are arranged in parallel, the total length L2 of the tensioner support device 1 is less than 2 / 3 of the first value L1, less than 3 / 5 of the first value L1, or less than 1 / 2 of the first value L1.

[0102] As an additional solution, by tilting the first rod 2 and the second rod 3 respectively relative to the interval changing device 4, the structure including the first rod 2, the interval changing device 4 and the second rod 3 (in other words, the tensioner support device 1) can also be reversed from a concave shape to a convex shape, wherein the concave shape has the interval changing device 4 as the bottom and the convex shape has the interval changing device 4 as the top.

[0103] (First runner 2 and second runner 3)

[0104] Preferably, the first rod 2 and the second rod 3 are electrically insulating rods. The first rod 2 and the second rod 3 are made of, for example, fiber reinforced plastic. When the first rod 2 and the second rod 3 are made of fiber reinforced plastic, the first rod 2 and the second rod 3 can be made lighter.

[0105] The length L3 of the first rod 2 (see Figure 4 ) is, for example, 50 cm or more, 60 cm or more, or 70 cm or more. The length L4 of the second rod 3 is, for example, 50 cm or more, 60 cm or more, or 70 cm or more. Since the lengths of the first rod 2 and the second rod 3 are each 50 cm or more, the separation distance between the first tensioner 110 hooked on the wire W and the second tensioner 120 hooked on the wire W and the operator's hand can be ensured.

[0106] like Figure 5 As shown in the example, the first umbrella body 25a and / or the second umbrella body 25b may also be installed on the outer peripheral surface of the first rod 2. The first umbrella body 25a prevents rainwater flowing on the outer surface of the first rod 2 from reaching the hands of the operator. In this way, the current path through the rainwater can be prevented from reaching the operator. The second umbrella body 25b defines the grip limit position that the operator is allowed to hold. More specifically, in the first rod 2, the operator is allowed to hold the portion closer to the base end than the second umbrella body 25b. Figure 5 In the described example, the second umbrella body 25b is arranged closer to the first base end portion 23 of the first rod 2 than the first umbrella body 25b. The second umbrella body 25b prevents rainwater flowing on the outer surface of the first rod 2 from reaching the hands of the worker.

[0107] The third umbrella body 35a and / or the fourth umbrella body 35b may also be installed on the outer peripheral surface of the second rod 3. The third umbrella body 35a prevents rainwater flowing on the outer surface of the second rod 3 from reaching the hands of the operator. In this way, the current path through the rainwater can be prevented from reaching the operator. The fourth umbrella body 35b defines the grip limit position that the operator is allowed to hold. More specifically, in the second rod 3, the operator is allowed to hold the portion closer to the base end than the fourth umbrella body 35b. Figure 5In the described example, the fourth body 35b is disposed at a position closer to the second base end portion 33 of the second rod 3 than the third body 35a. The fourth body 35b prevents rainwater flowing on the outer surface of the second rod 3 from reaching the hands of the worker.

[0108] (Wire support 60)

[0109] The first cut end Wd of the wire W (see if necessary) is efficiently cut. Fig.28 ) and the second cut end We of the wire (if necessary, refer to Fig.28 ) from the perspective of separate operations, the wire cutting tool 100 (more specifically, the wire tensioner support device 1) may also include at least one wire support member 60.

[0110] The wire support 60 is a member that supports the wire W in the region between the first tensioner 110 and the second tensioner 120. Figure 5 In the described example, the wire cutting tool 100 includes a first wire support 60a and a second wire support 60b. Figure 5 In the described example, the first wire support 60a is mounted on the first rod 2. The first wire support 60a may be mounted on the first rod 2 in a manner rotatable around the longitudinal axis of the first rod 2. The first wire support 60a may also be mounted on the first rod 2 at a position between the first umbrella body 25a and the first front end portion 21 of the first rod 2. Figure 5 In the described example, the second wire support 60b is mounted on the second rod 3. The second wire support 60b may be mounted on the second rod 3 in a manner rotatable around the longitudinal axis of the second rod 3. The second wire support 60b may also be mounted on the second rod 3 at a position between the third umbrella body 35a and the second front end portion 31 of the second rod 3.

[0111] exist Figure 6 In the example described, the first wire support 60a specifies a receiving space CP for receiving the wire W. The first wire support 60a has a frame member 61 and an opening and closing member 62 for opening and closing the opening of the frame member 61. The opening and closing member 62 is connected to the opening and closing operating member 63, and the opening and closing member 62 can be switched from a closed state to an open state (refer to arrow AR3) by operating the opening and closing operating member 63. When the opening and closing member 62 is in an open state, the operator can use a remote operation tool to insert the wire W into the receiving space CP of the first wire support 60a. In addition, when the opening and closing member 62 is in an open state, the operator can use a remote operation tool to take out the wire W from the receiving space CP of the first wire support 60a.

[0112] When separating the first cut end portion of the wire from the second cut end portion, for example, in a state where the wire connected to the first cut end portion Wd is already arranged in the receiving space CP, the first wire support 60a can be rotated around the longitudinal axis of the first rod 2 (see Fig.28 ).

[0113] exist Figure 5 In the described example, the second wire support 60b includes a frame member 64, an opening and closing member 65 for opening and closing the opening of the frame member 64, and an opening and closing operating member 66 for operating the opening and closing member 65. The frame member 64 has the same structure as the frame member 61, the opening and closing member 65 has the same structure as the opening and closing member 62, and the opening and closing operating member 66 has the same structure as the opening and closing operating member 63. Therefore, repeated descriptions of the frame member 64, the opening and closing member 65, and the opening and closing operating member 63 are omitted.

[0115] exist Figure 5 In the described example, the first base end portion 23 of the first rod 2 is connected to the first connection portion 41c of the interval changing device 4, and can be tilted around the first axis AX1. More specifically, the tensioner support device 1 has a first pin 91 arranged along the first axis AX1, and the first base end portion 23 of the first rod 2 and the first connection portion 41c of the interval changing device 4 are connected via the first pin 91. Preferably, the first rod 2 can rotate around the first axis AX1 relative to the interval changing device 4 by more than 1 / 4 turn (more preferably more than 1 / 3 turn or more than 1 / 2 turn). Figure 5 In the described example, the extending direction of the first axis AX1 is a direction perpendicular to the longitudinal direction of the first rod 2 .

[0116] exist Figure 5 In the example described, the second base end portion 33 of the second rod 3 is connected to the second connection portion 43c of the interval changing device 4, and can be tilted around the second axis AX2. More specifically, the tensioner support device 1 has a second latch 92 arranged along the second axis AX2, and the second base end portion 33 of the second rod 3 and the second connection portion 43c of the interval changing device 4 are connected via the second latch 92. Figure 5 In the example described, the second axis AX2 is parallel to the first axis AX1. Preferably, the second rod 3 can rotate about the second axis AX2 relative to the interval changing device 4 by more than 1 / 4 turn (more preferably more than 1 / 3 turn or more than 1 / 2 turn). Figure 5 In the described example, the extending direction of the second axis AX2 is a direction perpendicular to the longitudinal direction of the second rod 3 .

[0117] (First Locking Member 51 and Second Locking Member 56)

[0118] exist Figure 3 In the examples described (see Figure 3 ), the tensioner support device 1 has a first locking member 51, which fixes the inclination angle of the first rod 2 relative to the interval changing device 4 (more specifically, the inclination angle α1 of the first rod 2 relative to the first straight line SL, the first straight line SL is a straight line connecting the first connecting part 41c and the second connecting part 43c). In addition, the tensioner support device 1 has a second locking member 56, which fixes the inclination angle of the second rod 3 relative to the interval changing device 4 (more specifically, the inclination angle α2 of the second rod 3 relative to the first straight line SL, the first straight line SL is a straight line connecting the first connecting part 41c and the second connecting part 43c).

[0119] exist Figure 3 In the examples described (see Figure 3 ), the first locking member 51 can fix the inclination angle of the first rod 2 relative to the interval changing device 4 to maintain the first standing posture of the first rod 2 relative to the interval changing device 4. In addition, the second locking member 56 can fix the inclination angle of the second rod 3 relative to the interval changing device 4 to maintain the second standing posture of the second rod 3 relative to the interval changing device 4. The first locking member 51 can also fix the inclination angle α1 of the first rod 2 relative to the above-mentioned first straight line SL to a specified angle of not less than 70 degrees and not more than 110 degrees. For example, the first locking member 51 can also fix the inclination angle α1 of the first rod 2 relative to the above-mentioned first straight line SL to 90 degrees. In addition, the second locking member 56 can also fix the inclination angle α2 of the second rod 3 relative to the above-mentioned first straight line SL to a specified angle of not less than 70 degrees and not more than 110 degrees. For example, the second locking member 56 can also fix the inclination angle α2 of the second rod 3 relative to the above-mentioned first straight line SL to 90 degrees.

[0120] exist Figure 5 In the example described, the first locking component 51 can fix the inclination angle of the first rod 2 relative to the interval changing device 4, and the second locking component 56 can fix the inclination angle of the second rod 3 relative to the interval changing device 4, so as to maintain the U-shape formed by the first rod 2, the interval changing device 4 and the second rod 3 (in other words, maintain the overall shape of the tensioner support device 1 in a U-shape).

[0121] The first locking member 51 and the second locking member 56 are used to maintain the U-shape formed by the first rod 2, the interval changing device 4 and the second rod 3, so that the operator can more easily make the first tensioner 110 and the second tensioner 120 close to the wire W (refer to Fig.19 ).

[0122] exist Figure 3 In the examples described (see Figure 3 ), the first locking member 51 can fix the inclination angle of the first rod 2 relative to the interval changing device 4 to maintain the first horizontal position of the first rod 2 relative to the interval changing device 4. In addition, the second locking member 56 can fix the inclination angle of the second rod 3 relative to the interval changing device 4 to maintain the second horizontal position of the second rod 3 relative to the interval changing device 4. The first locking member 51 can also fix the inclination angle α1 of the first rod 2 relative to the above-mentioned first straight line SL to a specified angle of 160 degrees or more and 200 degrees or less. For example, the first locking member 51 can also fix the inclination angle α1 of the first rod 2 relative to the above-mentioned first straight line SL to 180 degrees. In addition, the second locking member 56 can also fix the inclination angle α2 of the second rod 3 relative to the above-mentioned first straight line SL to a specified angle of 160 degrees or more and 200 degrees or less. For example, the second locking member 56 can also fix the inclination angle α2 of the second rod 3 relative to the above-mentioned first straight line SL to 180 degrees.

[0123] exist Figure 7 In the described example, the first locking component 51 can fix the inclination angle of the first rod 2 relative to the interval changing device 4, and the second locking component 56 can fix the inclination angle of the second rod 3 relative to the interval changing device 4, so as to maintain the straight line shape formed by the first rod 2, the interval changing device 4 and the second rod 3 (in other words, the overall shape of the tensioner support device 1 is substantially maintained as a straight line shape).

[0124] By maintaining the straight line shape formed by the first rod 2, the interval changing device 4 and the second rod 3, the operator can avoid obstacles (such as the sleeve SV) arranged on the wire W, and make the first tensioner 110 and the second tensioner 120 close to the wire W (refer to Figure 7 In other words, the tensioner support device 1 in the first embodiment can also be configured to selectively perform: (1) when the overall shape of the tensioner support device 1 is in a U-shape, the first tensioner 110 and the second tensioner 120 are respectively close to the wire W (refer to Fig.19 ), (2) when the overall shape of the tensioner support device 1 is substantially a straight line, the first tensioner 110 and the second tensioner 120 are respectively brought close to the wire W (refer to Figure 7 ).

As an alternative, the first locking member 51 may lock the inclination angle of the first rod 2 relative to the interval changing device 4 so that the inclination angle of the first rod 2 relative to the interval changing device 4 becomes one of three or more angles. In this case, a plate having a plurality of engaging holes may be used as a mechanism for adjusting the inclination angle of the first rod 2 relative to the interval changing device 4, and the first locking member 51 is configured to selectively engage with the plurality of engaging holes, and the plurality of engaging holes are arranged at equal angle intervals around the first axis AX1. As an alternative, a daisy seat may be used as a mechanism for adjusting the inclination angle of the first rod 2 relative to the interval changing device 4.

Figure 8 In the described example, the first locking member 51 has an operating ring 52 that can be operated by a remote operating tool. When the operating ring 52 is operated against the urging force of the urging member 53, the first locking member 51 moves from the advanced position P1 to the retracted position P2. In this way, the angle fixation of the first rod 2 relative to the interval changing device 4 is released.

As an alternative, the first locking member 51 can also be disposed on the first rod 2, and the first locking member 51 can be engaged with the first connecting portion 41c of the interval changing device 4. As another alternative, the first locking member 51 can also be omitted.

The tensioner support device 1 may also include an energy imparting member 58 (e.g., a spring member) that imparts energy to the second locking member 56 from the retracted position toward the advanced position P3. Fig.11 In the described example, the second locking member 56 has an operating ring 57 that can be operated by a remote operating tool. When the operating ring 57 is operated against the urging force of the urging member 58, the second locking member 56 moves from the advanced position P3 to the retracted position. In this way, the angle fixation of the second rod 3 relative to the interval changing device 4 is released.

[0132] exist Fig.11 In the described example, the second locking member 56 (more specifically, the second locking pin 56a) is disposed on the interval changing device 4, and the second locking member 56 can be engaged with the second base end portion 33 of the second rod 3.

In other words, the structure for fixing the angle of the second rod 3 relative to the interval changing device 4 can also be omitted.

[0133] (First tensioner 110 and second tensioner 120)

[0134] exist Fig.12 In the example described, the first tensioner 110 is connected to the first front end 21 of the first rod 2 so as to be swingable about the third axis AX3. In addition, the second tensioner 120 is connected to the second front end 31 of the second rod 3 so as to be swingable about the fourth axis AX4.

[0135] The first tensioner 110 includes a first holding member 111 and a second holding member 112. The first portion Wa of the wire W can be held by the holding surface 111a of the first holding member 111 and the holding surface 112a of the second holding member 112. Fig.12 In the described example, the first tensioner 110 includes a swing member 113 and a first lever member 114. Fig.12 In the described example, the first gripping member 111 and the second gripping member 112 are connected via the swinging member 113. In addition, the first lever member 114 is swingably connected to the swinging member 113. The base end portion 114a of the first lever member 114 is connected to the first front end portion 21 of the first rod 2 so as to be swingable relative to the first rod 2.

[0136] exist Fig.13In the described example, when the first lever member 114 is pulled by the first rod 2, the swing member 113 swings relative to the first holding member 111. In addition, when the swing member 113 swings relative to the first holding member 111, the distance between the holding surface of the first holding member 111 and the holding surface of the second holding member 112 is reduced. In this way, the first portion Wa of the wire W is held by the first holding member 111 and the second holding member 112.

[0137] exist Fig.13 In the example described, the first tensioner 110 has a third locking member 115 and an operating portion 116 (more specifically, an operating ring) for operating the third locking member 115. The third locking member 115 limits the distance between the holding surface of the first holding member 111 and the holding surface of the second holding member 112 from increasing. Fig.13 In the described example, the third locking member 115 is supported by the first lever member 114 so that the third locking member 115 can move relative to the first lever member 114 .

[0138] When the operation portion 116 is operated by the remote operation tool, the front end of the third locking member 115 moves toward the swing member 113. The front end of the third locking member 115 abuts against the swing member 113, thereby limiting the swing of the swing member 113. In this way, the distance between the holding surface of the first holding member 111 and the holding surface of the second holding member 112 can be limited from expanding.

[0139] In addition, Fig.13 In the example described, the swing member 113 includes a first swing member 113a and a second swing member 113b arranged substantially parallel to the first swing member 113a. The first swing member 113a, the second swing member 113b, the first gripping member 111 and the first lever member 114 form a parallel link mechanism. Fig.13 In the described example, the first tensioner 110 includes two swing members (113a, 113b), but the first tensioner 110 may include only one swing member.

Fig.13 In the described example, the fall-off prevention member 117 is disposed on the swing member 113 (more specifically, the second swing member 113b), and is connected to the second holding member 112 in a manner that allows swinging around the fifth axis AX5. Fig.13In the example described, when the operating portion 116 is operated by the remote operating tool, the front end of the third locking member 115 moves toward the swing member 113, and the position of the fall-off preventing member 117 moves from the retreat position P4 (see Fig. 20 ) changes to the forward position P5 (refer to Fig.13 ), the retreat position P4 is a position that allows the first tensioner 110 to be hooked on the wire W, and the forward position P5 is a position that prevents the first tensioner 110 from falling off from the wire W.

[0141] The second tensioner 120 has a third holding member 121 and a fourth holding member 122. The third holding member 121 and the fourth holding member 122 can hold the second portion Wb of the wire W. Fig.13 In the described example, the second tensioner 120 includes the swing member 123 and the second lever member 124. The second tensioner 120 may also include a fourth locking member 125, an operating portion 126, and a fall-off prevention member 127.

[0142] The second tensioner 120 has the same structure as the first tensioner 110.

[0143] (First Example of Interval Changing Device 4)

[0144] exist Fig.14 In the described example, the interval changing device 4A includes a base 46, an operation block 47, a first block 41, and an operation member 45. The interval changing device 4A may include a second block 43 as an additional aspect.

[0145] The base 46 supports the operating block 47 so that the operating block 47 can move relative to the base 46 in the first direction DR1. The base 46 supports the first block 41 so that the first block 41 can move relative to the base 46 in the second direction DR2. In addition, the base 46 supports the second block 43 so that the second block 43 can move relative to the base 46 in the third direction DR3. In addition, it is preferred that the second direction DR2 is a direction perpendicular to the first direction DR1. In addition, it is preferred that the third direction DR3 is a direction opposite to the second direction DR2. The base 46 may be composed of one part or a combination of multiple parts.

[0146] When the operating member 45 is operated in the first operating direction MR1, the operating block 47 moves relative to the base 46 in the first direction DR1. In addition, when the operating member 45 is operated in the second operating direction MR2, the operating block 47 moves relative to the base 46 in the fourth direction DR4 opposite to the first direction DR1. Preferably, the second operating direction MR2 is the opposite direction to the first operating direction MR1. In addition, preferably, the fourth direction DR4 is the opposite direction to the first direction DR1. The operating block 47 may be composed of one part or a combination of multiple parts.

[0147] The first block 41 is provided with a first connection portion 41c. By operating the block 47 to move relative to the base 46 in the first direction DR1, the first block 41 moves in the direction approaching the second connection portion 43c, that is, the second direction DR2. Furthermore, by operating the block 47 to move relative to the base 46 in the first direction DR1, the first block 41 moves relative to the base 46 in the second direction DR2. On the other hand, by operating the block 47 to move relative to the base 46 in the fourth direction DR4, the first block 41 moves in the direction away from the second connection portion 43c, that is, the third direction DR3, and moves relative to the base 46 in the third direction DR3. The first block 41 may be composed of one part or a combination of a plurality of parts.

[0148] The second block 43 is provided with a second connection portion 43c. By operating the block 47 to move relative to the base 46 in the first direction DR1, the second block 43 moves in a direction approaching the first connection portion 41c, i.e., the third direction DR3. Furthermore, by operating the block 47 to move relative to the base 46 in the first direction DR1, the second block 43 moves relative to the base 46 in the third direction DR3. On the other hand, by operating the block 47 to move relative to the base 46 in the fourth direction DR4, the second block 43 moves in a direction away from the first connection portion 41c, i.e., the second direction DR2, and moves relative to the base 46 in the second direction DR2. The second block 43 may be composed of one part or a combination of a plurality of parts.

[0149] exist Fig.14 In the example described, the operating member 45 includes an operating portion 451 that can be engaged with a tool such as a remote operating tool, a threaded rod 453, and the like. Fig.14 In the described example, the base end portion 453 a of the screw rod 453 is connected to the operation portion 451 . In addition, the front end portion 453 b of the screw rod 453 is connected to the operation block 47 .

[0150] The threaded rod 453 has a central portion 453c between the base end portion 453a and the front end portion 453b in addition to the base end portion 453a and the front end portion 453b. A thread is formed on the outer peripheral surface of the central portion 453c. Fig.14 In the described example, the front end portion 453 b of the threaded rod 453 and the center portion 453 c of the threaded rod 453 are connected to each other so as to be relatively rotatable around the center axis of the threaded rod 453 .

[0151] The threaded rod 453 (more specifically, the central portion 453c of the threaded rod 453) is screwed to the base 46. Fig.14 In the example described, when the operating portion 451 is operated in the first operating direction MR1 around the central axis of the threaded rod 453, the threaded rod 453 and the operating block 47 move relatively to the first direction DR1 relative to the base 46 as a whole. As the operating block 47 moves relatively to the base 46 in the first direction DR1, the first connecting portion 41c of the first block 41 and the second connecting portion 43c of the second block 43 move toward each other. In this way, the interval between the first connecting portion 41c and the second connecting portion 43c is reduced, the interval between the first rod 2 and the second rod 3 is reduced, and the interval between the first tensioner 110 connected to the first rod 2 and the second tensioner 120 connected to the second rod 3 is reduced.

[0152] On the other hand, when the operating portion 451 is operated in the second operating direction MR2 around the central axis of the threaded rod 453, the threaded rod 453 and the operating block 47 will move relatively to the fourth direction DR4 relative to the base 46 as a whole. As the operating block 47 moves relatively to the fourth direction DR4 relative to the base 46, the first connecting portion 41c of the first block 41 and the second connecting portion 43c of the second block 43 move in a direction away from each other. In this way, the interval between the first connecting portion 41c and the second connecting portion 43c increases.

[0153] In addition, Fig.14 In the described example, in the wire cutting tool in an upright state (more specifically, in the wire cutting tool in a state where the front end 453b of the threaded rod 453 is located vertically above the base end 453a of the threaded rod 453), the first direction DR1 corresponds to the downward direction, and the fourth direction DR4 corresponds to the upward direction.

[0154] exist Fig.14 In the described example, the interval changing device 4A includes: a first guide portion 421 disposed on the first block 41 and a second guide portion 471 disposed on the operating block 47. The first guide portion 421 moves relative to the second guide portion 471. In addition, the first guide portion 421 and the second guide portion 471 convert the movement of the operating block 47 in the first direction DR1 into the movement of the first block 41 in the second direction DR2, which is a direction different from the first direction DR1. Fig.14 In the described example, the first guide portion 421 moves relative to the second guide portion 471 by the operation block 47 moving relative to the base 46 in the first direction DR1. As a result, the operation block 47 including the second guide portion 471 moves relative to the base 46 in the first direction DR1, and the first block 41 including the first guide portion 421 moves relative to the base 46 in the second direction DR2.

[0155] The first guide portion 421 may include a guide groove 421v extending in the inclined direction CR1, a guide hole extending in the inclined direction CR1, or an inclined surface formed on the outer surface of the first block 41 and extending in the inclined direction CR1, wherein the inclined direction CR1 is inclined relative to both the first direction DR1 and the second direction DR2. Fig.15 In the described example, the second guide portion 471 includes a guide pin 471p that moves relative to the first guide portion 421. Alternatively, the first guide portion 421 disposed on the first block 41 may include a guide pin, and the second guide portion 471 disposed on the operating block 47 may include a guide groove, a guide hole, or an inclined surface extending in the inclined direction CR1.

[0156] exist Fig.15 In the described example, the interval changing device 4A includes: a first auxiliary guide portion 423 disposed on the first block 41 and a second auxiliary guide portion 461 disposed on the base 46. The first auxiliary guide portion 423 moves relative to the second auxiliary guide portion 461. As a result, the first auxiliary guide portion 423 and the second auxiliary guide portion 461 assist the relative movement of the first block 41 relative to the base 46 in the second direction DR2.

[0157] The first auxiliary guide portion 423 may also include a guide groove 423v extending along the second direction DR2, and may also include a guide hole extending along the second direction DR2. Fig.15 In the described example, the second auxiliary guide portion 461 includes a guide pin 461p that moves relative to the first auxiliary guide portion 423. As an alternative, the first auxiliary guide portion 423 disposed on the first block 41 may include a guide pin, and the second auxiliary guide portion 461 disposed on the base 46 may include a guide groove or a guide hole extending along the second direction DR2.

[0158] exist Fig.14 In the described example, the interval changing device 4A has: a third guide portion 441 disposed on the second block 43 and a fourth guide portion 473 disposed on the operating block 47. The third guide portion 441 moves relative to the fourth guide portion 473. In addition, the third guide portion 441 and the fourth guide portion 473 convert the movement of the operating block 47 in the first direction DR1 into the movement of the second block 43 in the third direction DR3, which is a direction different from the first direction DR1. Fig.14 In the described example, the third guide portion 441 moves relative to the fourth guide portion 473 by the operation block 47 moving relative to the base 46 in the first direction DR1. As a result, the operation block 47 including the fourth guide portion 473 moves relative to the base 46 in the first direction DR1, and the second block 43 including the third guide portion 441 moves relative to the base 46 in the third direction DR3.

[0159] The third guide portion 441 may include a guide groove 441v extending in the inclined direction CR2, a guide hole extending in the inclined direction CR2, or an inclined surface formed on the outer surface of the second block 43 and extending in the inclined direction CR2, wherein the inclined direction CR2 is inclined relative to both the first direction DR1 and the second direction DR2. Fig.15In the described example, the fourth guide portion 473 includes a guide pin 473p that moves relative to the third guide portion 441. Alternatively, the third guide portion 441 disposed on the second block 43 may include a guide pin, and the fourth guide portion 473 disposed on the operating block 47 may include a guide groove, a guide hole, or an inclined surface extending in the inclined direction CR2.

[0160] exist Fig.15 In the described example, the interval changing device 4A includes: a third auxiliary guide portion 443 disposed on the second block 43 and a fourth auxiliary guide portion 463 disposed on the base 46. The third auxiliary guide portion 443 moves relative to the fourth auxiliary guide portion 463. As a result, the third auxiliary guide portion 443 and the fourth auxiliary guide portion 463 assist the relative movement of the second block 43 relative to the base 46 in the third direction DR3.

[0161] The third auxiliary guide portion 443 may also include a guide groove 443v extending along the third direction DR3, and may also include a guide hole extending along the third direction DR3. Fig.15 In the described example, the fourth auxiliary guide portion 463 includes a guide pin 463p that moves relative to the third auxiliary guide portion 443. Alternatively, the third auxiliary guide portion 443 disposed on the second block 43 may include a guide pin, and the fourth auxiliary guide portion 463 disposed on the base 46 may include a guide groove or a guide hole extending along the third direction DR3.

[0162] exist Fig.14 In the example described, when the operating member 45 is operated in the first operating direction MR1, both the first block 41 and the second block 43 move toward the direction close to the central axis of the threaded rod 453. As an alternative, Fig.16 As shown in the example, one of the first block 41 and the second block 43 may be fixed so as not to move relative to the base 46. When only one of the first block 41 and the second block 43 can move relative to the base 46 along the second direction DR2, the interval between the first connection portion 41c and the second connection portion 43c can still be changed.

[0163] exist Fig.14 or Fig.16 In the example described, when the operating member 45 is operated in the first operating direction MR1, the portion other than the base 46 of the interval changing device 4A is configured so that the protruding length from the upper end of the base 46 does not increase. Fig.14 or Fig.16In the described example, when the operating member 45 is operated in the first operating direction MR1, the operating member 45 and the operating block 47 move downward relative to the base 46, and the first block 41 (or the first block 41 and the second block 43) move relatively in the horizontal direction relative to the base 46. Therefore, even if the interval changing device 4A has a protruding portion that protrudes upward from the upper end of the base 46, when the operating member 45 is operated in the first operating direction MR1, the protruding length of the protruding portion does not increase.

[0164] By preventing the protruding length of the protruding portion from increasing, the protruding portion will not hinder the work after the wire W is cut.

[0165] exist Fig.14 or Fig.16 In the example described, the number of parts constituting the interval changing device 4A is small. Therefore, the assembly of the interval changing device 4A and the maintenance of the interval changing device 4A are relatively easy. In addition, the interval changing device 4A can be made lighter. In addition, the manufacturing cost of the interval changing device 4A can be reduced.

[0166] (Second Example of Interval Changing Device 4)

[0167] Reference Fig.17 Next, a second example of the interval changing device 4 will be described. Fig.17 In the described example, the interval changing device 4B includes an operating member 45, a first operating block 47a, a second operating block 47b, a first block 41 provided with a first connecting portion 41c, a second block 43 provided with a second connecting portion 43c, a first arm 481 connecting the first operating block 47a and the first block 41, a second arm 482 connecting the second operating block 47b and the first block 41, a third arm 483 connecting the first operating block 47a and the second block 43, and a fourth arm 484 connecting the second operating block 47b and the second block 43. The plurality of arms (481, 482, 483, 484) convert the movement of the first operating block 47a in the fourth direction DR4 and the movement of the second operating block 47b in the first direction DR1 into the movement of the first block 41 in the second direction DR2 perpendicular to the first direction DR1 and the movement of the second block 43 in the third direction DR3 opposite to the second direction DR2.

[0168] The operating member 45 includes an operating portion 451 that can be engaged with a tool such as a remote operating tool, a threaded rod 453, etc. The threaded rod 453 includes a threaded portion 453d and a reverse threaded portion 453e. The base end portion 453a of the threaded rod 453 is connected to the operating portion 451. In addition, the threaded portion 453d of the threaded rod 453 is screwed into the second operating block 47d, and the reverse threaded portion 453e of the threaded rod 453 is screwed into the first operating block 47a.

[0169] exist Fig.17 In the example described, when the operating member 45 (more specifically, the operating portion 451) is operated in the first operating direction MR1, the first operating block 47a screwed on the reverse threaded portion 453e moves in a direction away from the second operating block 47d (more specifically, in an upward direction), and the second operating block 47b screwed on the threaded portion 453d moves in a direction away from the first operating block 47a (more specifically, in a downward direction). In this way, the interval between the first operating block 47a and the second operating block 47d increases.

[0170] When the interval between the first operating block 47a and the second operating block 47d increases, the first arm 481, the second arm 482, the third arm 483, and the fourth arm 484 are tilted respectively to reduce the interval between the first connection portion 41c of the first block 41 and the second connection portion 43c of the second block 43. In this way, the interval between the first block 41 provided with the first connection portion 41c and the second block 43 provided with the second connection portion 43c is reduced, and as a result, the interval between the first rod 2 and the second rod 3 is reduced, and the interval between the first tensioner 110 connected to the first rod 2 and the second tensioner 120 connected to the second rod 3 is reduced.

[0171] exist Fig.17 In the examples described, and Fig.14 Compared with the example described above, the length of the threaded rod 453 protruding upward relative to the straight line connecting the first connecting portion 41c and the second connecting portion 43c is greater. Therefore, the threaded rod 453 (or the first operating block 47a) may cause an obstruction in the operation after the cutting operation of the wire W. However, in the first embodiment, it is not excluded to use Fig.17 The operation of the described interval changing device 4B.

[0172] (Third Example of Interval Changing Device 4)

[0173] Reference Fig.18 Next, a third example of the interval changing device 4 will be described. Fig.18 In the described example, the interval changing device 4C has: an operating part 45, a base 46, a first block 41 that can move relative to the base 46 in the second direction DR2, a second block 43 that can move relative to the base 46 in the third direction DR3, a first bevel gear 491, a second bevel gear 492 and a threaded rod 493.

[0174] The operating member 45 includes an operating portion 451 that can be engaged with a tool such as a remote operating tool, and a shaft 454. The base end of the shaft 454 is connected to the operating portion 451, and the front end of the shaft 454 is connected to the first bevel gear 491. The second bevel gear 492 is fixed to a threaded rod 493 extending along the second direction DR2. In addition, the threaded portion 493d of the threaded rod 493 is screwed to the first block 41, and the reverse threaded portion 493e of the threaded rod 493 is screwed to the second block 43.

[0175] exist Fig.18 In the example described, the first bevel gear 491 and the second bevel gear 492 are arranged in the internal space of the base 46. In addition, the first bevel gear 491 and the second bevel gear 492 convert the rotation of the operating member 45 around the central axis of the shaft 454 into the rotation of the threaded rod 493 around the central axis of the threaded rod 493. When the threaded rod 493 rotates around the central axis of the threaded rod 493, the first block 41 and the second block 43 move in a direction approaching each other (or, the first block 41 and the second block 43 move in a direction away from each other). For example, when the operating member 45 is operated in the first operating direction MR1, the first block 41 moves in the second direction DR2 to approach the second block 43, and the second block 43 moves in the third direction DR3 opposite to the second direction DR2 to approach the first block 41. In this way, the interval between the first connecting portion 41c arranged in the first block 41 and the second connecting portion 43c arranged in the second block 43 is reduced.

[0176] exist Fig.18 In the example described, the first block 41, the second block 43 and the base 46 each have a cylindrical shape extending along the second direction DR2. Therefore, in the third example, the dimension of the spacing change device 4C along the second direction DR2 is relatively large. In addition, the number of parts constituting the spacing change device 4C is large. Therefore, the assembly and maintenance of the spacing change device 4C are relatively complicated. However, in the first embodiment, the use of Fig.18 The operation of the described interval changing device 4C.

[0177] (Wire cutting method)

[0178] Next, refer to Figures 1 to 27 and Fig.34 , the wire cutting method in the first embodiment is described. Fig.34 This is a flowchart showing an example of the wire cutting method in the first embodiment.

[0179] In the wire cutting method of the first embodiment, a wire cutting tool is used to perform the wire cutting operation. The wire cutting tool used in the wire cutting method of the first embodiment may be the wire cutting tool 100 of the first embodiment or another wire cutting tool.

[0180] In the first step ST1, a wire cutting tool is prepared. The first step ST1 is a preparation step. Figure 5 As illustrated, the wire cutting tool prepared in the preparation step (first step ST1) includes: a first wire tensioner 110, a second wire tensioner 120, a first rod 2, a second rod 3 and a spacing change device 4, the first rod 2 is connected to the first wire tensioner 110, the second rod 3 is connected to the second wire tensioner 120, and the spacing change device 4 has a first connection portion 41c connected to the first rod 2 and a second connection portion 43c connected to the second rod 3. As an additional solution, the wire cutting tool prepared in the preparation step (first step ST1) may also include an umbrella body (25a, 25b, 35a, 35b) and / or a wire support 60. Figure 5 An example of the wire cutting tool 100 prepared in the preparation step is shown in FIG.

[0181] Since the first tensioner 110, the second tensioner 120, the first rod 2, the second rod 3, the interval changing device 4, the umbrella body (25a, 25b, 35a, 35b), and the wire support 60 have been described above, repeated descriptions of these structures are omitted.

[0182] In the second step ST2, the first tensioner 110 and the second tensioner 120 are hooked on the wire W respectively. The second step ST2 is a hooking step. Fig.19 and Fig. 20 As shown in the example, the hooking step (second step ST2) is performed in a state where the first rod 2 and the second rod 3 are respectively raised upward from the interval changing device 4. More specifically, the hooking step is performed in a state where the first rod 2 is in a first raised posture raised from a first straight line, the first straight line connecting the first connecting portion 41c and the second connecting portion 43c. In addition, the hooking step is performed in a state where the second rod 3 is in a second raised posture raised from a first straight line, the first straight line connecting the first connecting portion 41c and the second connecting portion 43c.

[0183] like Fig.19 and Fig. 20 As shown in the example, the hooking step can also be performed when the first rod 2, the interval changing device 4 and the second rod 3 are arranged in a U shape (in other words, when the overall shape of the tensioner support device 1 is in a U shape). In addition, the hooking step can also be performed when the first rod 2 and the second rod 3 are arranged in parallel.

[0184] like Fig.19 and Fig. 20 As shown in the example, the hooking step may be performed while the operator holds the first base end portion 23 of the first rod 2 and the second base end portion 33 of the second rod 3. Fig.19 and Fig. 20 In the described example, the hooking step can be performed without using a remote operating wand.

[0185] like Fig.19 and Fig. 20 As shown in the example, the hooking step can also be performed in a state where the inclination angle of the first rod 2 relative to the interval changing device 4 has been locked by the first locking member 51 (more specifically, the posture of the first rod 2 relative to the interval changing device 4 has been maintained in the first standing posture by the first locking member 51). In addition, the hooking step can also be performed in a state where the inclination angle of the second rod 3 relative to the interval changing device 4 has been locked by the second locking member 56 (more specifically, the posture of the second rod 3 relative to the interval changing device 4 has been maintained in the second standing posture by the second locking member 56). Figure 3 As shown in the example, in the first standing posture, the angle (α1) formed between the first straight line SL connecting the first connecting portion 41c and the second connecting portion 43c and the first rod 2 may be 90 degrees, or a predetermined angle of 70 degrees or more and 110 degrees or less. In addition, in the second standing posture, the angle (α2) formed between the first straight line SL and the second rod 3 may be 90 degrees, or a predetermined angle of 70 degrees or more and 110 degrees or less.

[0186] exist Fig.19 and Fig. 20 In the example described, since the first rod 2 and the second rod 3 are in a standing position, the operator can easily perform the hooking step. For example, since the direction of the gravity acting on the first tensioner 110 is roughly consistent with the extension direction of the first rod 2, the operator can easily support the first tensioner 110 via the first rod 2. In addition, since the direction of the gravity acting on the second tensioner 120 is roughly consistent with the extension direction of the second rod 3, the operator can easily support the second tensioner 120 via the second rod 3. In addition, since the distance between the first tensioner 110 and the second tensioner 120 is short, the operator can easily perform the operation of hooking both the first tensioner 110 and the second tensioner 120 on the wire W.

[0187] As an alternative, Figure 7As shown in the example, the hooking step (second step ST2) is performed when the first rod 2 and the second rod 3 are in a horizontal position relative to the interval changing device 4. More specifically, the hooking step (second step ST2) is performed when the overall shape of the tensioner support device 1 is substantially a straight line. The state of the wire W (for example, the arrangement of obstacles such as a sleeve installed on the wire W) may be taken into consideration. Fig.19 and Fig. 20 The hooking steps shown and Figure 7 One of the hooking steps shown.

[0188] In the third step ST3, the fall-off prevention component 117 and the fall-off prevention component 127 are set to prevent the first tensioner 110 from falling off from the wire W through the fall-off prevention component 117 of the first tensioner 110, and to prevent the second tensioner 120 from falling off from the wire W through the fall-off prevention component 127 of the second tensioner 120. The third step ST3 is a step of setting the fall-off prevention component. Fig.21 In the example described, the step of setting the fall-off prevention component includes: operating the operating unit 116 of the first tensioner 110 by a remote operation tool, thereby changing the position of the fall-off prevention component 117 of the first tensioner 110 from the retreat position (refer to Fig. 20 ) changes to the forward position (refer to Fig.21 ). In addition, the step of setting the fall-off prevention component includes: operating the operating part 126 of the second tensioner 120 by a remote operation tool, thereby changing the position of the fall-off prevention component 127 of the second tensioner 120 from the retreat position (refer to Fig. 20 ) changes to the forward position (refer to Fig.21 ).

[0189] exist Figures 19 to 21 In the example described, the step of setting the fall-off prevention component (third step ST3) is a step independent of the hooking step (second step ST2). As an alternative, the third step ST3 (step of setting the fall-off prevention component) can also be configured to be automatically executed in conjunction with the execution of the hooking step (second step ST2). In addition, when the wire cutting tool 100 does not have a fall-off prevention component (117, 127), the third step ST3 can also be omitted.

[0190] As an alternative or additional solution, in the third step ST3, the distance between the holding surface of the first holding member 111 and the holding surface of the second holding member 112 may be reduced. Fig.21In the example described, the following two are performed: the operating portion 116 of the first tensioner 110 is operated by a remote operating tool, thereby moving the fall-prevention component 117 of the first tensioner 110 from the retreat position to the advance position, and reducing the distance between the holding surface of the first holding component 111 and the holding surface of the second holding component 112. In addition, in the third step ST3, the distance between the holding surface of the third holding component 121 and the holding surface of the fourth holding component 122 can also be reduced. Fig.21 In the described example, the following two are performed: the operating portion 126 of the second tensioner 120 is operated by a remote operating tool, thereby moving the fall prevention component 127 of the second tensioner 120 from the retracted position to the forward position, and reducing the distance between the holding surfaces of the third holding component 121 and the fourth holding component 122.

[0191] In addition, in the third step ST3, the gap between the holding surface of the first holding member 111 and the holding surface of the second holding member 112 is reduced to such an extent that the first tensioner 110 is not fixed to the wire W. In addition, in the third step ST3, the gap between the holding surface of the third holding member 121 and the holding surface of the fourth holding member 122 is reduced to such an extent that the second tensioner 120 is not fixed to the wire W.

[0192] In the fourth step, the lock of the inclination angle of the first rod 2 relative to the interval changing device 4 is released, and the lock of the inclination angle of the second rod 3 relative to the interval changing device 4 is released. The fourth step ST4 is a lock release step.

[0193] exist Fig.21 In the described example, the locking release of the tilt angle of the first rod 2 relative to the interval changing device 4 is performed by operating the first locking member 51 (more specifically, the operating ring 52 of the first locking member 51). This locking release can also be performed using a tool or by directly operating the operating ring 52 by hand. By this locking release, the first rod 2 can be tilted relative to the interval changing device 4.

[0194] exist Fig.21 In the described example, the locking release of the tilt angle of the second rod 3 relative to the interval changing device 4 is performed by operating the second locking member 56 (more specifically, the operating ring 57 of the second locking member 56). This locking release can also be performed using a tool or by directly operating the operating ring 57 by hand. By this locking release, the second rod 3 can be tilted relative to the interval changing device 4.

[0195] In addition, when the wire cutting tool 100 does not have the first locking member 51 and the second locking member 56, or when the hooking step is performed without fixing the tilt angle with the first locking member 56 and the second locking member 56, the fourth step ST4 can be omitted.

[0196] In addition, when the wire cutting method includes both the third step ST3 (the step of setting the fall-off prevention component) and the fourth step ST4 (the step of releasing the lock), it is preferred that the third step ST3 is executed before the execution of the fourth step ST4. However, in the first embodiment, the situation in which the third step ST3 is executed after the execution of the fourth step ST4 is not excluded.

[0197] In the fifth step ST5, the first rod 2 and the second rod 3 are tilted relative to the interval changing device 4. The fifth step ST5 is a first tilting step. The first tilting step (fifth step ST5) is performed by moving the interval changing device 4 upward. The upward movement of the interval changing device 4 is performed, for example, using the remote control rod T1. Fig. 22 In the described example, when the tip of the remote control rod T1 is attached to the operating member 45 of the interval changing device 4, the interval changing device 4 is moved upward by moving the remote control rod T1 upward. Fig. 22 In the described example, the first tilting step includes tilting the first rod 2 relative to the interval changing device 4 around a first axis AX1 perpendicular to the first rod 2 , and tilting the second rod 3 relative to the interval changing device 4 around a second axis AX2 perpendicular to the second rod 3 .

[0198] like Figure 21 to Figure 23 As illustrated, the first tilting step (fifth step ST5) may also include: moving the first tensioner 110 away from the second tensioner 120 along the wire W, and moving the second tensioner 120 away from the first tensioner 110 along the wire W. In addition, if the step of setting the fall-off prevention component (third step ST3) has been performed before the first tilting step is performed, when the first tensioner 110 and the second tensioner 120 move along the wire W, the first tensioner 110 and the second tensioner 120 can be appropriately prevented from falling off from the wire W.

[0199] exist Figures 19 to 23In the example described, from the start of the hooking step (second step ST2) to the completion of the first tilting step (fifth step ST5), the position of the interval changing device 4 does not substantially change from a planar perspective. Imagine a situation where an operator located in the cage of a high-altitude working vehicle performs the above-mentioned hooking step and the above-mentioned first tilting step. In this case, from the start of the hooking step (second step ST2) to the completion of the first tilting step (fifth step ST5), there is no need to change the position of the cage of the high-altitude working vehicle. In addition, from the start of the hooking step (second step ST2) to the completion of the first tilting step (fifth step ST5), the operator does not need to change his or her own position. Thus, the operator can quickly and easily perform the steps including the hooking step and the first tilting step.

[0200] In the sixth step ST6, the wire W is supported by at least one wire support member 60. The sixth step ST6 is a wire support step. The wire support step (the sixth step ST6) may also include: inserting the wire W into the receiving space CP (refer to the receiving space CP of the first wire support member 60a) Figure 6 ). In addition, the wire supporting step (sixth step ST6) may also include: inserting the wire W into the receiving space of the second wire supporting member 60b. Fig.24 The status after the wire support step has been executed is shown in .

[0201] In the seventh step ST7, the first portion Wa of the wire W is held by the first tensioner 110, and the second portion Wb of the wire W is held by the second tensioner 120. The seventh step ST7 is a wire holding step.

[0202] exist Fig.25 In the example described, the wire holding step (the seventh step ST7) includes: moving the interval changing device 4 upward so that the interval changing device 4 protrudes upward more than the wire W. More specifically, Fig.25 As shown in the example, the wire holding step may also include: moving the interval changing device 4 upward so that the first base end 23 of the first rod 2 is located higher than the first front end 21 of the first rod 2, and the second base end 33 of the second rod 3 is located higher than the second front end 31 of the second rod 3. Fig.25 In the described example, the upward movement of the interval changing device 4 is performed by moving the remote operating rod T1 connected to the operating member 45 of the interval changing device 4 upward.

[0203] By moving the interval changing device 4 in this way, the interval between the first tensioner 110 and the second tensioner 120 is reduced, and the first tensioner 110 and the second tensioner 120 respectively hold the wire W. More specifically, the first lever member 114 of the first tensioner 110 is pulled toward the second tensioner 120, thereby the swing member 113 swings, and the distance between the holding surface of the first holding member 111 and the holding surface of the second holding member 112 is reduced. In this way, the first portion Wa of the wire W can be held by the first tensioner 110 (more specifically, by the holding surface of the first holding member 111 and the holding surface of the second holding member 112). In addition, the second lever member 124 of the second tensioner 120 is pulled toward the first tensioner 110, thereby the swing member 123 swings, and the distance between the holding surface of the third holding member 121 and the holding surface of the fourth holding member 122 is reduced. In this way, the second portion Wb of the wire W can be held by the second tensioner 120 (more specifically, by the holding surface of the third holding member 121 and the holding surface of the fourth holding member 122 ).

[0204] As an alternative or additional solution, the wire holding step (seventh step ST7) may also include: operating the operating portion 116 of the first tensioner 110 by a remote operating tool, thereby reducing the gap between the holding surface of the first holding member 111 and the holding surface of the second holding member 112. In addition, the wire holding step (seventh step ST7) may also include: operating the operating portion 126 of the second tensioner 120 by a remote operating tool, thereby reducing the gap between the holding surface of the third holding member 121 and the holding surface of the fourth holding member 122.

[0205] In the eighth step ST8, the interval between the first connection portion 41c of the interval changing device 4 and the second connection portion 43c of the interval changing device 4 is reduced (see Fig.26 The eighth step ST8 is a step of reducing the interval. Fig.26 As illustrated, by executing the interval reduction step (eighth step ST8), a slack portion Wc of the wire W is formed between the first tensioner 110 and the second tensioner 120. Fig.26 In the described example, the slack portion Wc is bent upward with respect to the straight line connecting the first portion Wa of the wire W and the second portion Wb of the wire W.

[0206] exist Fig.26 In the example described, the interval reduction step (eighth step ST8) is performed by operating the operating member 45 of the interval changing device 4 in the first operating direction MR1 using the remote operating stick T1. Fig.25 and Fig.26In the example described, both the wire holding step (seventh step ST7) and the interval reduction step (eighth step ST8) are performed by operating the remote operating rod T1. More specifically, the wire holding step (seventh step ST7) is performed by moving the remote operating rod T1 upward, and the interval reduction step (eighth step ST8) is performed by rotating the remote operating rod T1 around the central axis of the remote operating rod T1. Thus, the wire holding step and the interval reduction step can be performed continuously and quickly.

[0207] In addition, the interval changing device 4 may also be Fig.14 or Fig.16 The interval changing device 4A shown as an example may also be Fig.17 The interval changing device 4B shown as an example may also be Fig.18 The interval changing device 4C shown as an example may be another interval changing device.

[0208] like Fig. 27 As shown in the ninth step ST9, the wire W is cut at the slack portion Wc. The ninth step ST9 is a cutting step. By executing the cutting step (ninth step ST9), the wire W is cut into two parts. The cutting step (ninth step ST9) is performed using an arbitrary cutting tool T2. By executing the cutting step, a first cut end Wd and a second cut end We are formed on the wire W.

[0209] In the wire rod cutting method of the first embodiment, the first rod 2 and the second rod 3 are respectively tilted relative to the interval changing device 4 (see Figure 21 to Figure 23 ). In addition, the interval between the first connecting portion 41c and the second connecting portion 43c is changed so that the interval between the first rod 2 and the second rod 3 is reduced (refer to Fig.26 As a result, the wire W can be easily cut using a wire cutting tool. More specifically, Fig.19 and Fig. 20 As shown in the example, the first tensioner 110 and the second tensioner 120 can be easily brought close to the wire W. In addition, by moving the interval changing device 4 upward, the first rod 2 and the second rod 3 can be tilted relative to the interval changing device 4 (see Figure 21 to Figure 23 ). By this tilting, the interval between the first tensioner 110 and the second tensioner 120 is expanded, and a wire W of a sufficient length can be arranged between the first tensioner 110 and the second tensioner 120 (refer to Fig.23 ). In addition, by operating the operating member 45 in the first operating direction MR1, the interval between the first connecting portion 41c and the second connecting portion 43c can be reduced (refer to Fig.26The distance between the first connecting portion 41c and the second connecting portion 43c is reduced, that is, the distance between the first tensioner 110 and the second tensioner 120 can be reduced. As a result, the wire W can be effectively relaxed in the area between the first tensioner 110 and the second tensioner 120 (in other words, the relaxation of the wire W can be ensured). By cutting the relaxed wire W, the wire W can be easily cut (refer to Fig. 27 ).

[0210] (Wire processing method)

[0211] Reference Figures 1 to 35 , the wire material processing method in the first embodiment is described. Fig.34 and Fig.35 1 is a flowchart showing an example of the wire material processing method in the first embodiment. The wire material processing method in the first embodiment includes the steps described in the wire material cutting method in the first embodiment and a plurality of steps to be performed thereafter.

[0212] After the ninth step ST9 is performed, in the tenth step ST10, the first cut end Wd formed by cutting the slack portion Wc and the second cut end We formed by cutting the slack portion Wc are separated to be away from each other. The tenth step ST10 is an end separation step. The end separation step (the tenth step ST10) is performed by rotating the wire support 60 around the first rod 2 or the second rod 3. Fig.28 In the described example, the end separation step (the tenth step ST10) includes: rotating the first wire support 60a around the first rod 2, thereby rotating the first cut end Wd of the wire W around the first rod 2. Alternatively, the end separation step (the tenth step ST10) may also include: rotating the second wire support 60b around the second rod 3, thereby rotating the second cut end We of the wire W around the second rod 3.

[0213] After any operation is performed in a state where the first cut end Wd and the second cut end We are separated, in the eleventh step ST11, the first cut end Wd and the second cut end We are connected. The eleventh step ST11 is an end connection step. The end connection step (eleventh step ST11) includes, for example: stripping the coating from the wire at each of the first cut end Wd and the second cut end We, and connecting the first cut end Wd and the second cut end We via the sleeve SV. Fig.29 As illustrated, the end connecting step (eleventh step ST11 ) may include covering the first end of the sleeve SV with the first sleeve cover SC1 , and may include covering the second end of the sleeve SV with the second sleeve cover SC2 .

[0214] In the twelfth step ST12, the first tensioner 110 releases the grip of the first portion Wa of the wire W, and the second tensioner 120 releases the grip of the second portion Wb of the wire W. The twelfth step ST12 is a grip release step. Fig.30 In the example described, the gripping release step (the twelfth step ST12) includes: operating the operating portion 116 of the first tensioner 110 by the remote control tool T3 (see arrow AR6). By operating the operating portion 116 of the first tensioner 110, the locking of the first tensioner 110 by the third locking member 115 is released (more specifically, the position restriction of the second gripping member 112 relative to the first gripping member 111 is released). In addition, Fig.30 In the example described, the gripping release step (the twelfth step ST12) includes: operating the operating portion 126 of the second tensioner 120 by the remote operating tool T3 (see arrow AR7). By operating the operating portion 126 of the second tensioner 120, the locking of the second tensioner 120 by the fourth locking member 125 is released (more specifically, the position restriction of the fourth holding member 122 relative to the third holding member 121 is released).

[0215] As an additional solution, Fig.31 As shown in the example, the gripping release step (the twelfth step ST12) may also include: moving the interval changing device 4 upward so that the interval changing device 4 protrudes upward more than the wire W. More specifically, Fig.31 As illustrated, the gripping release step may also include: moving the interval changing device 4 upward so that the first base end 23 of the first rod 2 is positioned higher than the first front end 21 of the first rod 2, and the second base end 33 of the second rod 3 is positioned higher than the second front end 31 of the second rod 3. Fig.31 In the described example, the upward movement of the interval changing device 4 is performed by moving the remote operating rod T1 , which is the operating member 45 connected to the interval changing device 4 , upward.

[0216] By the upward movement of the interval changing device 4, the second holding member 112 of the first tensioner 110 is pressed downward by the wire W, and the fourth holding member 122 of the second tensioner 120 is pressed downward by the wire W. As a result, the distance between the holding surface of the first holding member 111 and the holding surface of the second holding member 112 is increased, and the distance between the holding surface of the third holding member 121 and the holding surface of the fourth holding member 122 is increased. In this way, the first tensioner 110 effectively releases the holding of the first part Wa of the wire W, and the second tensioner 120 effectively releases the holding of the second part Wb of the wire W.

[0217] In the thirteenth step ST13, the first rod 2 and the second rod 3 are tilted relative to the interval changing device 4. The thirteenth step ST13 is a second tilting step. The second tilting step (the thirteenth step ST13) includes: moving the interval changing device 4 downward, and moving the first tensioner 110 and the second tensioner 120 in a direction close to each other. Fig.32 In the example described, the downward movement of the interval changing device 4 is performed by moving the remote control rod T1 downward, which is the operating member 45 connected to the interval changing device 4. Fig.32 In the described example, moving the first tensioner 110 and the second tensioner 120 in a direction approaching each other includes: moving the first tensioner 110 and the second tensioner 120 along the wire W, respectively. Moving the first tensioner 110 along the wire W and moving the second tensioner 120 along the wire W may be performed simultaneously or sequentially. In addition, moving the first tensioner 110 along the wire W may be performed by pulling the first tensioner 110 toward the second tensioner 120 using any remote operation tool. Moving the second tensioner 120 along the wire W may be performed by pulling the second tensioner 120 toward the first tensioner 110 using any remote operation tool.

[0218] By executing the second tilting step (the thirteenth step ST13), the shape of the structure including the first rod 2, the interval changing device 4 and the second rod 3 (in other words, the shape of the tensioner support device 1) is changed from a straight line shape to a U-shape (refer to Fig.33 ).

[0219] In the fourteenth step ST14, the first tensioner 110 and the second tensioner 120 are removed from the wire W. The fourteenth step ST14 is a removal step. The removal step (the fourteenth step ST14) is performed when the shape of the structure including the first rod 2, the interval change device 4 and the second rod 3 (in other words, the shape of the tensioner support device 1) is in a U-shape. Fig.33 As illustrated, the removing step may be performed by the operator moving the first rod 2 and the second rod 3 while the operator holds the first base end 23 of the first rod 2 and the second base end 33 of the second rod 3 .

In addition, any constituent element can be omitted in the first embodiment or the modification.
