Description

[Technical field]

[0001] The present invention relates to a technique for attaching a binding wire (hereinafter referred to as a "binding wire") that has been preliminarily processed into a spiral shape to an electric wire, and more specifically, to a binding wire device that can attach a binding wire to an electric wire by rotating a ring-shaped rotating body, and a method for installing a binding wire using the same, and a method for removing the binding wire. [Background technology]

[0002] Power plants generate electricity at several thousand to tens of thousands of volts, but to avoid losses due to electrical resistance, this electricity is converted to ultra-high voltage of around hundreds of thousands of volts before being transmitted. The voltage is then gradually reduced at each substation, such as ultra-high voltage substations, primary substations, secondary substations, and distribution substations, before being supplied to factories and other facilities, and the voltage is further reduced by pole-mounted transformers before being supplied to homes. In any case, the electricity generated at power plants is supplied to users via transmission and distribution lines that use electric wires and cables (hereinafter collectively referred to as "transmission lines, etc."), and naturally, there are a great number of transmission lines, etc., deployed throughout the country.

[0003] Power lines include overhead transmission lines (overhead transmission lines and overhead distribution lines) that are strung on power poles, and underground transmission lines (underground transmission lines and underground distribution lines) that are buried underground, and three-phase (i.e., three) transmission lines are sometimes laid in parallel. In other words, in the case of overhead transmission lines, three transmission lines are strung side-by-side between power poles. In this case, spacers may be installed on the transmission lines to ensure that they are spaced apart from each other, or to prevent them from falling if one of the wires is cut. Transmission lines may also be fixed to high-voltage pin insulators.

[0004] When attaching spacers to power lines or fastening them to high-voltage pin insulators, a binding wire that has already been processed into a spiral shape (sometimes called a "preform binding wire") is generally used. The binding wire is wound around the power lines, which are then fastened to the spacer or high-voltage pin insulator via the binding wire. The work of winding binding wire around power lines is often considered live-line work that does not stop the transmission of electricity, and therefore, when working with high-voltage power lines, it is considered "direct live-line work" in which the worker wears insulating protective equipment such as high-voltage rubber gloves and insulating jackets and directly touches the high-voltage power lines.

[0005] However, this direct live-line work involves the risk of electric shock and is vulnerable to weather conditions. In recent years, various technologies related to the so-called "hot stick method" using an insulated control rod such as a stick or pliers have been proposed. For example, Patent Document 1 discloses a technology for attaching a wrapped binding wire using a "U"-shaped tool attached to the control rod. Patent Document 2 discloses a technology for attaching a wrapped binding wire using a hook-shaped tool attached to the control rod that rotates in a vertical plane, and Patent Document 3 discloses a technology for attaching a wrapped binding wire using a hook-shaped tool attached to the control rod. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2016-46984 A [Patent Document 2] JP 2008-42990 A [Patent Document 3] JP 2004-153900 A Summary of the Invention [Problem to be solved by the invention]

[0007] However, in all conventional hot stick methods, the task of attaching the binding wire to the power transmission line, etc. is extremely difficult, and since the work is performed from a distance using a control rod, considerable training is required in advance. Furthermore, the technology disclosed in Patent Document 1 requires someone to hold the binding wire and someone to attach the binding wire to the power transmission line, etc., which means that the work costs including the labor of two workers are high.

[0008] The object of the present invention is to solve the problems associated with the prior art, that is, to provide a binding wire device that can easily attach and detach a binding wire to and from a power transmission line, etc., and a method for installing and removing a binding wire using the same. [Means for solving the problem]

[0009] The present invention was made based on an unprecedented idea that utilizes an annular (ring-shaped) member included in a support such as a rotary stick, in other words, by rotating the annular member holding the binding wire around a cable (such as a power line), the binding wire is wrapped around the cable.

[0010] The binding wire device of the present invention is a device for winding a binding wire around a cable, and includes an annular rotating body, a locking body installed on the rotating body, a support body for supporting the rotating body, and a rotation mechanism for rotating the rotating body. Of these, the rotating body is formed with an insertion space through which the cable is inserted and rotates around the cable, and the locking body rotates around the cable together with the rotating body. The insertion space is divided by the locking body to form a "cable insertion space" and a "binding wire insertion space." Then, when the cable is inserted into the cable insertion space and the binding wire temporarily fixed to the cable is inserted into the binding wire insertion space, the rotating body is rotated by the rotation mechanism, and the binding wire is wound around the cable.

[0011] The binding wire device of the present invention may be configured so that the binding wire insertion space is a closed space surrounded by the rotating body and the locking body.

[0012] The binding wire device of the present invention may be configured so that the binding wire insertion space is a partially open space with a gap between the tip of the engaging body and the rotating body.

[0013] The binding wire device of the present invention may have a recess in which the cable can be placed, formed in a portion of the engaging body on the cable insertion space side.

[0014] The binding wire device of the present invention may also be one in which the rotating body has a "main member" and an "opening / closing member." The opening / closing member is hinged to the main member so that a part of the annular rotating body is open. That is, when the opening / closing member rotates in one direction relative to the main member, the insertion space is in a "constrained state (a state in which the cable inserted in the insertion space does not deviate from the insertion space)," whereas when the opening / closing member rotates in the other direction relative to the main member, the insertion space is in an "open state (a state in which an opening for accommodating the cable is formed in the insertion space)."

[0015] The binding wire device of the present invention may further include a temporary fixing device. This temporary fixing device is configured to include a hook-shaped "upper clamp" and a "lower clamp." The lower clamp moves toward and away from the upper clamp. The cable and the binding wire can be clamped by the upper clamp and the lower clamp that is close to the upper clamp.

[0016] The binding wire device of the present invention may further include a rod-shaped operating support. This operating support is directly (or via a connecting jig) detachably attached to the support. In this case, the rotation mechanism is a mechanism for rotating the rotating body by rotating an operating handle provided on the operating support.

[0017] The binding wire device of the present invention may be configured such that the rotating body is rotated by rotating an operating handle. Note that the direction of rotation of the rotating body changes depending on the direction of rotation of the operating handle.

[0018] The binding wire installation method of the present invention is a method for winding a binding wire around a cable using the binding wire device of the present invention, and includes a temporary fixing step, a cable insertion step, a binding wire insertion step, and a winding step. In the temporary fixing step, the binding wire is temporarily fixed to the cable, and in the cable insertion step, the cable is inserted into the cable insertion space. In the binding wire insertion step, the binding wire temporarily fixed to the cable is inserted into the binding wire insertion space, and in the winding step, the binding wire is wound around the cable by rotating a rotating body using a rotating mechanism.

[0019] The binding wire installation method of the present invention can also be a method of temporarily fixing the binding wire using a temporary fixing device. In this case, in the temporary fixing step, the binding wire is temporarily fixed to the cable using the temporary fixing device attached to the operating pole, and the operating pole is removed from the temporary fixing device that temporarily fixed the binding wire to the cable. In the winding step, the operating pole removed from the temporary fixing device is attached to a support, and the rotating body is rotated by rotating an operating handle provided on the operating pole.

[0020] The binding wire installation method of the present invention is a method for removing a binding wire wound around a cable using the binding wire device of the present invention, and includes a cable insertion step, a binding wire insertion step, and a removal step. In the cable insertion step, the cable is inserted into the cable insertion space, and in the binding wire insertion step, the binding wire is inserted into the binding wire insertion space from its end. In the removal step, the binding wire is removed from the cable by rotating a rotating body using a rotating mechanism. Effect of the Invention

[0021] The bind wire device, the bind wire installation method, and the bind wire removal method of the present invention have the following effects. (1) By simply inserting the binding wire into the binding wire insertion space and then rotating the rotating body, the binding wire can be wound around the cable or removed from the cable, making the work easier to perform than with prior art. (2) There is no need to rely on skilled workers, meaning that workers can be easily secured. (3) The work from temporarily fixing the binding wire to winding it can be done by a single person, which reduces the cost of workers. (4) The so-called “hot stick method” is possible, which reduces the risk of electric shock and other accidents and can be carried out without being affected by weather conditions.

[0023] An embodiment of the binding wire device, the binding wire installation method, and the binding wire removal method of the present invention will be described with reference to the drawings. For convenience, the various electrical conductors used in power transmission lines, power distribution lines, etc. will be referred to simply as "cables".

[0024] 1.Overview First, an outline of the present invention will be described with reference to Fig. 1. Fig. 1 is a perspective view that shows a schematic state of winding a bind wire BW (preform bind wire) around a cable CB using a bind wire device 100 of the present invention. As shown in this figure, the bind wire device 100 of the present invention can attach the bind wire BW to the cable CB or remove the bind wire BW wound around the cable CB. The bind wire BW is a linear member that has been processed into a spiral shape in advance as shown in Fig. 2(a), and is attached so as to be wound around the cable CB as shown in Fig. 2(b).

[0025] In FIG. 1, the binding wire BW is temporarily fixed to the cable CB by the temporary fixing device 300, and in this state, the attachment / detachment device 200 winds the binding wire BW around the cable CB. Specifically, the cable CB and the binding wire BW are housed inside the attachment / detachment device 200, and then a rotating body, which will be described later, is rotated around the cable CB. As a result, the attachment / detachment device 200 automatically moves in the axial direction of the cable CB (white arrow in FIG. 1) as the rotating body rotates, due to the effect that the binding wire BW is processed into a spiral shape. Then, the binding wire BW rotates together with the rotating body, so that the binding wire BW is wound around the cable CB. In addition, by using the operation support 400, that is, by installing the attachment / detachment device 200 at the top of the operation support 400, it is possible to realize a so-called "hot stick method" in which the cable CB is not directly touched. As the operation support 400, a so-called rotary stick can be used, or a simple rod-shaped or tubular columnar body (hereinafter referred to as a "stick") can be used.

[0026] 2. Binding wire device The binding wire device 100 of the present invention will be described in detail. The binding wire installation method of the present invention is a method of attaching a binding wire to a cable using the binding wire device 100, and the binding wire removal method of the present invention is a method of removing a binding wire from a cable using the binding wire device 100. Therefore, the binding wire device 100 will be described first, and then the binding wire installation method and the binding wire removal method of the present invention will be described.

[0027] 1, the binding wire device 100 includes an attachment / detachment device 200, and may further include a temporary fixing device 300 and an operation support 400. Each of the main elements that make up the binding wire device 100 will be described in detail below.

[0028] (Detachable device) FIG. 3 is a front view showing the attachment / detachment device 200, and FIG. 4 is a front view showing the rotating body 210. Note that FIG. 3(a) shows a state in which a part of the rotating body 210 is open, and FIG. 3(b) and FIG. 4 show a state in which the rotating body 210 is closed. As shown in FIG. 4, the rotating body 210 is annular (ring-shaped) with a circular space (hereinafter referred to as an "insertion space") formed therein, and rotates by a rotation mechanism with the center of the insertion space as the center of rotation. This rotation mechanism can be configured to rotate using gears, for example, or can be configured to rotate using belts or rollers. In addition, the rotating body 210 can be configured to rotate by an operator operating a handle, or can be configured to rotate the rotating body 210 using other power such as electric or hydraulic. Note that FIG. 4 shows an example in which the rotating body 210 rotates in one direction (clockwise in the figure), but the rotating body 210 can also be configured to rotate in both directions. For example, when an operator rotates a rotary handle in one direction, the rotor 210 rotates in a forward direction (e.g., clockwise), and when the operator rotates the handle in the other direction, the rotor 210 rotates in the reverse direction (e.g., counterclockwise).

[0029] 3 and 4, the rotating body 210 can be configured to include a main member 211 and an opening / closing member 212. One end of the opening / closing member 212 (the lower end in the figure) is hinged to the main member 211, so that the opening / closing member 212 can rotate relative to the main member 211. When the opening / closing member 212 rotates in one direction (clockwise in FIG. 4), the rotating body 210 is in an "open state" in which the opening AP is formed, as shown in FIG. 3(a), and when the opening / closing member 212 rotates in the other direction (counterclockwise in FIG. 3), the rotating body 210 is in a "constrained state" in which the opening AP is closed, as shown in FIG. 3(b).

[0030] The support 230 supports the rotating body 210. However, the support 230 itself does not rotate. In other words, the rotating body 210 rotates relative to the support 230 while being supported by the support 230. The locking body 220 is installed on the rotating body 210, so that the locking body 220 rotates together with the rotating body 210. Also, by installing the locking body 220 on the rotating body 210, the insertion space of the rotating body 210 is divided into two spaces, and a "binding wire insertion space SB" and a "cable insertion space SC" are formed as shown in FIG. 4. Of these, the binding wire insertion space SB is a space inside the locking body 220 surrounded by the locking body 220 and the rotating body 210, while the "cable insertion space SC" is a space outside the locking body 220 in the insertion space. Since the locking body 220 rotates together with the rotating body 210, the binding wire insertion space SB also rotates together with the rotating body 210.

[0031] When using the bind wire device 100 of the present invention, that is, when attaching the bind wire BW to the cable CB or removing the bind wire BW from the cable CB, the cable CB is accommodated in the cable insertion space SC and the bind wire BW is inserted into the bind wire insertion space SB as shown in Fig. 5. Then, the rotation mechanism rotates the rotating body 210 around the cable CB, thereby rotating the bind wire BW in the bind wire insertion space SB around the cable CB. When the rotating body 210 starts to rotate, the cable CB in the cable insertion space SC automatically approaches the bind wire BW, so as to be arranged as shown in Fig. 5.

[0032] The support 230 may be one that closes the binding wire insertion space SB (hereinafter referred to as the "closed type locking body 220C"), or one that opens a part of the binding wire insertion space SB (hereinafter referred to as the "open type locking body 220G"). When the closed type locking body 220C is used, the binding wire insertion space SB is a closed space surrounded by the closed type locking body 220C and the rotating body 210 as shown in FIG. 5. On the other hand, when the open type locking body 220G is used, a gap GP is generated between the tip of the open type locking body 220G (the right end in the figure) and the rotating body 210 as shown in FIG. 6, so that the binding wire insertion space SB is a partly open space. As shown in FIG. 7, a recess RC for placing the cable CB may be formed in the back of the support 230 on the cable insertion space SC side (the portion shown by the broken line in FIG. 5 and FIG. 6). Fig. 7 is a partial front view showing a part of the locking body 220 in which a recess RC is formed on the cable insertion space SC side. This recess RC can be formed in a curved shape as shown in Fig. 7(a) or in a linearly bent shape as shown in Fig. 7(b). Of course, the recess RC can be formed on the back of the open-type locking body 220G or the closed-type locking body 220C.

[0033] As shown in Fig. 3(a), an opening AP is formed in the rotating body 210 in the open state, and the cable CB can be inserted and removed from the cable insertion space SC through this opening AP. On the other hand, as shown in Fig. 3(b) and Fig. 5, the rotating body 210 in the constrained state has a closed annular opening AP, and therefore the cable CB can be restricted from escaping (disengaging) from the cable insertion space SC. Therefore, it is preferable to set the rotating body 210 in the open state when the cable CB is accommodated in the cable insertion space SC, and to set the rotating body 210 in the constrained state when the bind wire BW is rotated around the cable CB.

[0034] (operation column) FIG. 8 is a front view showing a state in which the attachment / detachment device 200 is attached to the top of the operation column 400. As shown in this figure, the attachment / detachment device 200 can be attached to a part of the operation column 400, and can also be detached from the operation column 400. As described above, a so-called rotary stick can be used as the operation column 400, or a stick can be used. For example, the attachment / detachment device 200 can be attached to the operation column 400 by using the first column attachment part 250 (FIG. 3) provided on the support body 230 of the attachment / detachment device 200. In this case, a part (or the whole) of the operation column 400 is made into a hollow tube, and the attachment / detachment device 200 is attached by inserting the first column attachment part 250 into the hollow part (for example, the top). In this way, the attachment / detachment device 200 can be attached to the operating column 400 by directly connecting the support body 230 (particularly the first column mounting portion 250) and the operating column 400, or the attachment / detachment device 200 can be attached to the operating column 400 by connecting the support body 230 and the operating column 400 via a separate "connection jig."

[0035] As shown in FIG. 8, by installing the attachment / detachment device 200 on the top of the operation column 400, it is possible to realize a so-called "hot stick method" that does not require direct contact with the cable CB. In this case, it is preferable that the operation of rotating the rotating body 210 by the rotation mechanism can also be performed at a position away from the cable CB. For example, in FIG. 8, an operation handle 240 as a rotation mechanism is provided below the operation column 400, and the rotating body 210 is rotated by rotating this operation handle 240. This allows the worker to rotate the rotating body 210 at a position away from the cable CB, that is, to attach the binding wire BW to the cable CB or to remove the binding wire BW from the cable CB.

[0036] (Temporary Fixation Device) 9 is a diagram showing a temporary fixing device 300, where (a) is a perspective view and (b) is a front view. As shown in this figure, the temporary fixing device 300 temporarily fixes the binding wire BW to the cable CB, and is configured to include an upper clamping body 310 and a lower clamping body 320, and can also be configured to further include a slide locking tool 330 and a second support pole mounting part 340.

[0037] The slide locking tool 330 locks a part of the bind wire BW to the temporary fixing device 300. This slide locking tool 330 can be structured to slide as shown in Fig. 10. With this, when the slide locking tool 330 is slid with a part of the bind wire BW set in place, a part of the bind wire BW is housed in the slide locking tool 330, and as a result, a part of the bind wire BW is locked.

[0038] The upper clamping body 310 is hook-shaped, and can accommodate the cable CB inside thereof, as shown in FIG. 9(b). The lower clamping body 320 is structured to move toward and away from the upper clamping body 310. With this, when the lower clamping body 320 is brought closer to the upper clamping body 310 with the cable CB accommodated inside the upper clamping body 310, the cable CB can be clamped by the upper clamping body 310 and the lower clamping body 320. That is, the bind wire BW can be temporarily fixed to the cable CB by locking a part of the bind wire BW to the temporary fixing device 300 by the slide locking tool 330 and clamping the cable CB between the upper clamping body 310 and the lower clamping body 320.

[0039] As with the attachment / detachment device 200, the temporary fixing device 300 can also be configured to be attached to the top of the operation column 400. As described above, a so-called rotary stick or a stick can be used as the operation column 400. For example, in FIG. 9(b), the second column attachment part 340 is hollow and tubular with an open lower end, and the temporary fixing device 300 is attached to the operation column 400 by inserting the top of the operation column 400 into the hollow part. In this way, the temporary fixing device 300 can be directly attached to the operation column 400, or the temporary fixing device 300 can be attached to the operation column 400 via a separate "connection jig."

[0040] (Example of use) An example of using the binding wire device 100 of the present invention will be described with reference to FIG. 11. FIG. 11 is a step diagram showing a procedure for winding a binding wire BW around a cable CB using the binding wire device 100 of the present invention. First, as shown in FIG. 10, a part of the binding wire BW is locked to the temporary fixing device 300, and the temporary fixing device 300 with the part of the binding wire BW locked is attached to the top of the operation support 400. Then, as shown in FIG. 11(a), the cable CB is accommodated inside the upper clamp 310, and the lower clamp 320 is moved closer to the upper clamp 310 to clamp the cable CB, thereby temporarily fixing the binding wire BW to the cable CB. At this time, if the structure is such that the lower clamp 320 approaches the upper clamp 310 by operating the operation handle 240 provided below the operation support 400, the temporary fixing here can also be a "hot stick method".

[0041] Once the binding wire BW is temporarily fixed to the cable CB, the operation support 400 is removed from the temporary fixing device 300 as shown in Fig. 11(b). Even after the operation support 400 is removed, the binding wire BW remains temporarily fixed to the cable CB. Then, the attachment / detachment device 200 is attached to the top of the operation support 400. At this time, the operation support 400 removed from the temporary fixing device 300 can be used as is, or a separate operation support 400 for the attachment / detachment device 200 can be used.

[0042] When the attachment / detachment device 200 is attached to the top of the operation column 400, the cable CB is accommodated in the cable insertion space SC and the binding wire BW is inserted into the binding wire insertion space SB as shown in FIG. 11(c). In the case where the closed type locking body 220C is used as the locking body 220, the rotating body 210 is set in the "open state", and the cable CB is accommodated at a position away from the temporarily fixed binding wire BW, and the attachment / detachment device 200 is moved toward the binding wire BW, and the binding wire BW is inserted into the binding wire insertion space SB from its end. At this time, the rotating body 210 can be set in the "restrained state" and then the binding wire BW can be inserted into the binding wire insertion space SB, or the rotating body 210 can be set in the "restrained state" after the binding wire BW is inserted into the binding wire insertion space SB. On the other hand, in the case where the open-type locking body 220G is used as the locking body 220, the rotating body 210 is also set in the "open state," and the attachment / detachment device 200 is moved in a direction substantially perpendicular to the axis of the cable CB (to the left in the figure) from the side of the cable CB (however, in the range where the bind wire BW is temporarily fixed) as shown in Fig. 12, while the cable CB is accommodated in the cable insertion space SC and the bind wire BW is accommodated in the bind wire insertion space SB. Note that if the opening / closing member 212 is structured to rotate (open and close) by operating the operation handle 240 provided below the operation pillar 400, the work here can also be considered as the "hot stick method."

[0043] When the attachment / detachment device 200 with the bind wire BW inserted in the bind wire insertion space SB is placed near the temporary fixing device 300, the rotation mechanism rotates the rotating body 210. As a result, the attachment / detachment device 200 automatically moves toward the end of the bind wire BW while the bind wire BW in the bind wire insertion space SB rotates around the cable CB, causing the bind wire BW to wind around the cable CB.

[0044] When the bind wire BW is wound around the cable CB from near the temporary fixing device 300 to one end of the bind wire BW, the temporary fixing device 300 is removed from the cable CB as shown in Fig. 11(d). At this time, it is preferable to remove the operation support 400 from the attachment / detachment device 200, attach the operation support 400 to the temporary fixing device 300, and then remove the temporary fixing device 300.

[0045] When the temporary fixing device 300 is removed from the cable CB, the cable CB is accommodated in the cable insertion space SC as shown in FIG. 11(e), and the bind wire BW is inserted into the bind wire insertion space SB. The procedure at this time is the same as that described in FIG. 11(c). Then, the rotating body 210 is rotated by the rotation mechanism. As a result, the attachment / detachment device 200 automatically moves in a direction toward the other end of the bind wire BW (the opposite end in FIG. 11(c)), while the bind wire BW in the bind wire insertion space SB rotates around the cable CB, i.e., the bind wire BW is wound around the cable CB.

[0046] 3. How to install the binding wire Next, the bind wire installation method of the present invention will be described. The bind wire installation method of the present invention is a method for attaching a bind wire BW to a cable CB using the bind wire device 100 described above. Therefore, we will avoid any overlapping description with the description of the bind wire device 100, and will only describe the contents unique to the bind wire installation method of the present invention. In other words, the contents not described here are the same as those described in "2. Bind Wire Device".

[0047] Fig. 13 is a flow diagram showing the flow of the main steps of the binding wire installation method of the present invention. When attaching the binding wire BW to the cable CB using the binding wire device 100 of the present invention, the binding wire BW is first temporarily fixed to the cable CB using the temporary fixing device 300 (Step 501 in Fig. 13). After the binding wire BW is temporarily fixed to the cable CB, the operation support 400 is removed from the temporary fixing device 300, and the attachment / detachment device 200 is attached to the top of the operation support 400. Next, the cable CB is accommodated in the cable insertion space SC of the rotating body 210 in the "open state" (Step 502 in Fig. 13), and the end of the binding wire BW is inserted into the binding wire insertion space SB (Step 503 in Fig. 13).

[0048] In the case where the closed type locking body 220C is used as the locking body 220, the rotating body 210 is put in the "open state", the cable CB is accommodated at a position away from the temporarily fixed bind wire BW, and the attachment / detachment device 200 is moved toward the bind wire BW while inserting the end of the bind wire BW into the bind wire insertion space SB. At this time, the rotating body 210 can be put in the "constrained state" and then the bind wire BW can be inserted into the bind wire insertion space SB, or the rotating body 210 can be put in the "constrained state" after the bind wire BW has been inserted into the bind wire insertion space SB. On the other hand, in the case where the open-type locking body 220G is used as the locking body 220, the rotating body 210 is also set in the "open state", and the attachment / detachment device 200 is moved from the side of the cable CB (however, in the range where the bind wire BW is temporarily fixed) in a direction substantially perpendicular to the axis of the cable CB (to the left in the figure) as shown in Fig. 12, while accommodating the cable CB in the cable insertion space SC and accommodating the bind wire BW in the bind wire insertion space SB. Then, when the attachment / detachment device 200 with the bind wire BW inserted in the bind wire insertion space SB is placed near the temporary fixing device 300, the rotating body 210 is rotated by the rotation mechanism (Step 504 in Fig. 13). As a result, the attachment / detachment device 200 automatically moves toward the end of the bind wire BW, while the bind wire BW in the bind wire insertion space SB rotates around the cable CB, that is, the bind wire BW is wound around the cable CB.

[0049] When the bind wire BW is wound around the cable CB from near the temporary fixing device 300 to one end of the bind wire BW, the temporary fixing device 300 is removed from the cable CB (Step 505 in FIG. 13). After the temporary fixing device 300 is removed from the cable CB, the same operations (Steps 502 to 504) are repeated for the bind wire BW on the opposite side until all of the bind wire BW is wound around the cable CB.

[0050] 4. How to remove the binding wire Next, the bind wire removal method of the present invention will be described. The bind wire removal method of the present invention is a method for removing the bind wire BW from the cable CB using the bind wire device 100 described above. Therefore, we will avoid overlapping explanations with the contents explained about the bind wire device 100, and only explain the contents unique to the bind wire removal method of the present invention. In other words, the contents not described here are the same as those explained in "2. Bind wire device" or "3. Bind wire installation method".

[0051] Fig. 14 is a flow diagram showing the flow of the main steps of the binding wire removal method of the present invention. When removing the binding wire BW from the cable CB using the binding wire device 100 of the present invention, first, the cable CB is accommodated in the cable insertion space SC of the rotating body 210 in the "open state" (Step 601 in Fig. 14). At this time, the cable CB is accommodated at a position away from the binding wire BW wound around the cable CB.

[0052] When the cable CB is accommodated in the cable insertion space SC, the opening / closing member 212 is closed to place the rotating body 210 in a "restrained state," and the attachment / detachment device 200 is moved toward the binding wire BW, and the "front end" of the binding wire BW wound around the cable CB is inserted into the binding wire insertion space SB from the end of the binding wire BW (Step 602 in FIG. 14). Then, the rotating body 210 is rotated by the rotation mechanism (Step 603 in FIG. 14). As a result, the attachment / detachment device 200 automatically moves toward the "rear end" of the binding wire BW, while the binding wire BW in the binding wire insertion space SB rotates around the cable CB, i.e., the binding wire BW is gradually removed from the cable CB. [Industrial Applicability]
