  FIG. 1 is a front view of a power transmission line binding device 101 attached to a common operation rod 201. A transmission line bundling device 101 for bundling a plurality of overhead transmission lines 13 (see FIGS. 10 and 11) covered with a protective tube 14 has a triangular plate-shaped transmission line holding unit 102. The unit 102 forms the basic form. The power transmission line holding part 102 has three storage holes 103 so that the three overhead power transmission lines 13 covered with the protective tube 14 can be bundled. These storage holes 103 are formed in a size and shape capable of storing the protective tube 14 covering the overhead power transmission line 13.

  At three edge portions of the power transmission line holding portion 102, introduction ports 104 communicating with the storage holes 103 are formed. The path from these inlets 104 to the storage holes 103 is the introduction part 105, and is formed in a size and shape that allows the protective tube 14 to be introduced from the inlets 104 to the storage holes 103.

  The power transmission line holding part 102 is provided with a lid part 106 that opens and closes each inlet 104. These lid portions 106 are attached to a rotating piece 107 that is rotatably attached to the power transmission line holding portion 102. The rotating piece 107 supports the lid portion 106 so as to be displaced between a position for opening and closing the introduction port 104 by rotating. Further, the power transmission line holding unit 102 is provided with a clamper 108 that clamps the rotating piece 107 at a position where the lid unit 106 closes the introduction port 104. The clamper 108 has an action piece 109 that controls the clamping and releasing of the rotating piece 107 by a pushing operation and a pulling operation. The lid 106, the rotating piece 107, and the clamper 108 will be described in detail later with reference to FIGS.

  The power transmission line binding device 101 has an adapter 110 that is detachably attached to the common operation rod 201. The adapter 110 is fixedly provided at the lower edge of the power transmission line holding unit 102 and is detachably attached to the mounting unit 202 of the common operation rod 201. Next, the attachment / detachment structure of the power transmission line binding device 101 with respect to the common operation rod 201 will be described.

  FIG. 2 is a front view showing an example of the common operation bar 201 used when bundling a plurality of overhead power transmission lines 13. The common operation rod 201 has a mounting portion 202 at its tip. Various adapters suitable for the work to be performed can be mounted on the mounting unit 202 and used.

  FIG. 3 is an enlarged perspective view showing the mounting portion 202 provided at the distal end portion of the common operation rod 201. The mounting portion 202 is configured such that a pair of mounting pins 204 protrude from the outer peripheral surface of a cylindrical base body 203, and a push rod 205 and a push ring 206 are provided on the base body 203. The push rod 205 is provided so as to be able to move in and out of the head of the base 203, and the push ring 206 is provided below the base 203 so as to be slidable along the longitudinal direction of the common operation rod 201. The push rod 205 is urged in a direction of protruding from the base body 203 by a coil spring (not shown). The push ring 206 is urged toward the base 203 by a coil spring (not shown). Therefore, the push rod 205 and the push ring 206 are urged in the same direction.

  FIG. 4 is a perspective view of the power transmission wire binding device 101. Here, first, the adapter 110 included in the power transmission line binding device 101 will be described, and the mounting structure of the adapter 110 to the mounting portion 202 of the common operation rod 201 will be introduced. The adapter 110 has a shape that allows the common operation rod 201 to be attached to the attachment portion 202. That is, the adapter 110 is formed with a fitting hole 111 that allows the base 203 of the mounting portion 202 to be fitted. A pair of T-shaped pin grooves 112 that allow insertion of the mounting pins 204 included in the mounting portion 202 are formed in a shape cut from the fitting holes 111. These pin grooves 112 have folded portions 113 that are folded back at the end portions thereof.

  As shown in FIG. 1, in a state where the transmission line binding device 101 is mounted on the common operation rod 201, a pair of mounting pins 204 provided on the common operation rod 201 side is provided with pin grooves provided on the adapter 110 side. The adapter 110 is fixed to the mounting portion 202 of the common operation rod 201. That is, in order to attach the power transmission line binding device 101 to the common operation rod 201, the base 203 included in the attachment portion 202 of the common operation rod 201 is fitted into the fitting hole 111 of the adapter 110 and the pin groove 112 is fitted. The mounting pin 204 is inserted. At this time, the push rod 205 and the push ring 206 are pushed in, and an urging force is applied to the adapter 110. The adapter 110 is pushed to a position where the mounting pin 204 can move in the pin groove 112 against the urging force, and the power transmission cable binding device 101 is rotated in the horizontal direction to the movement limit position at that position. When the hand is released at this position, the adapter 110 is urged by the push rod 205 and the push ring 206, and a pair of mounting pins 204 provided on the common operation rod 201 side is provided with a pin groove 112 provided on the adapter 110 side. The power line binding device 101 is fixed to the common operation rod 201.

  FIG. 5 is an enlarged perspective view showing a mechanism for holding the overhead power transmission line 13 in the power transmission cable binding apparatus 101. Here, such a mechanism mainly including the lid 106, the rotating piece 107, and the clamper 108 will be described.

  A pair of L-shaped support pieces 115 are screwed to the power transmission line holding portion 102 so as to be adjacent to the introduction port 104 at one edge where the introduction port 104 is formed. Pin holes 115a are formed in these support pieces 115, and a pair of action piece arms 109a constituting the action pieces 109 are rotatably attached to these pin holes 115a by pins 109b. The action piece 109 is formed by connecting a pair of action piece arms 109a with a connecting rod 109c. The pin 109b is formed to protrude from the end of the action piece arm 109a opposite to the connecting rod 109c. The action piece 109 is rotatably attached to the support piece 115 by preventing a pin 109b inserted through the pin hole 115a formed in the support piece 115 by an E ring 116.

  The rotation piece 107 that supports the lid portion 106 is a wire-like member that is rotatably attached to a pair of action piece arms 109 a included in the action piece 109. That is, the rotating piece 107 is formed by bending a wire-like member into a U-shape and bending both ends further at right angles toward the outside. Here, the central portion of the U-shape is called the hooking portion 107a, and the portions bent at right angles at both ends are called the insertion portion 107b. An insertion hole 109d is formed in the pair of action piece arms 109a so as to be positioned in the vicinity of the pin 109b. By inserting the insertion portion 107b of the rotation piece 107 into these insertion holes 109d, the rotation piece 107 is rotatably attached to the action piece 109.

  Here, the dimensional relationship between the rotating piece 107 and the action piece 109 will be described. The action piece 109 forms a space between the pair of action piece arms 109a from the position at which the rotation piece 107 is supported to the position at which the connecting rod 109c is provided. The rotating piece 107 is formed in such a size that it can rotate without hitting the connecting rod 109c in the space.

  The lid portion 106 is configured such that a hard lid portion main body 106b is bonded and fixed to a base portion 106a formed of sheet metal, and a flexible elastic body 106c is bonded and fixed to the lid portion main body 106b. The lid main body 106b is bonded and fixed to the base 106a by, for example, screwing. The elastic body 106c is bonded and fixed to the lid main body 106b using, for example, an adhesive. Such a lid portion 106 is attached to the hooking portion 107a of the rotating piece 107 by bending both ends of the base portion 106a.

  An elastic hook 117 is screwed to one edge of the power transmission line holding portion 102 where the introduction port 104 is formed, on the side opposite to the pair of support pieces 115 with the introduction port 104 interposed therebetween. The hook 117 is a hook for hooking the hook portion 107 a of the rotating piece 107. When the action piece 109 is tilted to the opposite side of the hook 117 with the hook portion 107 a being hooked on the hook 117, the hook portion 107 a of the rotating piece 107 is hooked on the hook 117. At this time, the dimensions of each part are determined so that the rotating piece 107 maintains a pulled state between the insertion hole 109 d of the pair of action piece arms 109 a of the action piece 109 and the hook 117. That is, as shown in FIG. 1, the insertion portion 107b of the rotating piece 107 inserted into the insertion hole 109d has a position where the hooking portion 107a of the rotating piece 107 is hooked on the hook 117 and the rotation of the action piece 109. It is positioned on one edge side of the power transmission line holding unit 102 with respect to the line connecting the moving center (position of the pin 109b). This is because the action piece 109 is tilted to the opposite side of the hook 117 while the hook 107 is hooked on the hook 117, the insertion part 107 b of the rotating piece 107 is hooked to the hooking part 107 a of the rotating piece 107. This is a result of overcoming a position on a line connecting the position hooked by 117 and the rotation center of the action piece 109 (the position of the pin 109b). At this time, the elastic hook 117 slightly bends to allow such overcoming. As a result, turning force in a direction approaching one edge of the transmission line holding unit 102 acts on the rotating piece 107. In order to rotate in the opposite direction, the line connecting the position where the hook 107a of the rotating piece 107 is hooked to the hook 117 and the center of rotation of the action piece 109 (the position of the pin 109b). You have to get over the upper position and require some external force. Thereby, the rotation piece 107 is clamped. Here, a clamper 108 that clamps the rotating piece 107 at a position where the lid 106 closes the introduction port 104 is configured.

  Further, as shown in FIGS. 1, 4 and 5, the pair of action piece arms 109 a constituting the action piece 109 is bent in a dogleg shape. Thereby, even if the action piece 109 is completely tilted to the side opposite to the hook 117, a gap is formed between the connecting rod 109c of the action piece 109 and one edge of the power transmission line holding portion 102.

  FIG. 6 is a front view showing an example of the Kikuza adapter 301 attached to the common operation rod 201 used for bundling a plurality of overhead power transmission lines 13. The Chrysanthemum adapter 301 has a structure in which an action part 303 having a Chrysanthemum 302 is connected and fixed to an adapter part having the same configuration as that of the adapter 110. The Chrysanthemum 302 has a structure in which a plurality of concave and convex portions 302a are arranged on the circumference, and has a thumbscrew 302b at the center. Therefore, it can be freely attached to and detached from the mounting portion 202 of the common operation rod 201.

  FIG. 7 is a front view showing an example of a bind hammer 401 that is attached to the Kikuza adapter 301 and is used for bundling a plurality of overhead power transmission lines 13. The bind striker 401 has a chrysanthemum 402 that is detachably attached to the chrysanthemum 302 of the chrysanthemum adapter 301, and has a flange 403 and a hitting stick 404 as an action part. The Kikuza 402 has a size and shape that allows the concave and convex portions 402a to be fitted to the concave and convex portions 302a provided on the chrysanthemum 302 of the Kikuza adapter 301 to be arranged on the circumference and fit into the thumbscrew 302b. A mounting groove 402b is provided. Therefore, the Kikuza adapter 301 can be fixed to the bind hammer 401 by loosening the butterfly screw 302b of the chrysanthemum adapter 301 and inserting and tightening the screw portion of the butterfly screw 302b into the mounting groove 402b of the bind hammer 401. . In this state, the bind striker 401 can be attached to the common operation rod 201 via the Kikuza adapter 301.

  The operation | work which binds the three overhead power transmission lines 13 which covered the protection pipe | tube 14 in such a structure with the power transmission line binding tool 101 is demonstrated. First, two common operation bars 201 are prepared. One is fitted with a power line binding device 101. On the other side, a bind hammer 401 to which a Kikuza adapter 301 is fixed is attached. Then, with the lid 106 opened and the introduction port 104 opened, the protective tube 14 is inserted into the accommodation hole 103 from each introduction port 104 and the introduction unit 105. At this time, the clamper 108 is in a state as shown in FIG. Therefore, the hook portion 107a of the rotating piece 107 is hooked on the hook 117 using the flange portion 403 of the bind hammer 401, and in this state, the action piece arm 109a of the action piece 109 is turned to the opposite side to the hook 117. Let me defeat. Thereby, the rotation piece 107 is clamped by the hook 117, and the cover part 106 maintains the state which closed the inlet 104. FIG. By performing such an operation individually for the three protective pipes 14, the three overhead power transmission lines 13 covered with the protective pipes 14 can be bundled by the transmission line bundling tool 101. Therefore, after binding the three overhead power transmission lines 13 with the power transmission line binding device 101, the common operation rod 201 is pushed and rotated to rotate the mounting portion 202 of the common operation rod 201 from the adapter 110 of the power transmission line binding device 101. It can be removed and the work is completed.

  When the power transmission line binding device 101 is removed from the three overhead power transmission lines 13 bound by the power transmission line binding device 101, the common operation rod 201 is attached to the adapter 110 of the power transmission line binding device 101. For mounting, the common operation rod 201 is pushed up with the base 203 of the mounting portion 202 of the common operation rod 201 inserted into the fitting hole 111 of the adapter 110, and the mounting pin 204 settles on the folded portion 113 of the pin groove 112. The common operation rod 201 may be rotated up to. In this state, the bind hammer 401 attached to the other common operation rod 201 is used, the tip of the hook 403 is hooked on the action piece arm 109a of the action piece 109, and the action piece 109 is turned to the hook 117 side. Move. As a result, the rotating piece 107 falls off the hook 117, and the clamp is released. At this time, since the lid portion 106 is in a state where the introduction port 104 is opened, the protective tube 14 placed on the overhead power transmission line 13 can be dropped from the storage hole 103 by operating the common operation rod 201. By performing such an operation individually for the three protective pipes 14, all of the three overhead power transmission lines 13 covered with the protective pipes 14 can be dropped from the transmission line binding device 101.

  As described above, according to the present embodiment, the protective tube 14 covering the overhead power transmission line 13 is accommodated in the accommodation hole 103 from the introduction portion 105, and the introduction port 104 is closed by the lid portion 106 by the clamp of the clamper 108. Thus, the plurality of protective tubes 14 can be reliably bundled without being damaged. In addition, since the clamp 110 of the clamper 108 can be clamped and released in the state where the adapter 110 of the power line binding device 101 is mounted on the mounting portion 202 of the common operation rod 201, the operation piece 109 can be pressed and pulled. Bundling and bundling work of a plurality of overhead power transmission lines 13 can be performed safely and easily by an indirect hot wire method.

  Moreover, since the cover part 106 has the elastic body 106c which has a softness | flexibility in the part which faces the accommodation hole 103, the protective tube 14 accommodated in the accommodation hole 103 can be elastically suppressed with the elastic body 106c. Accordingly, the movement of the protective tube 14 inside the storage hole 103 is suppressed, and damage to the protective tube 14 that is likely to occur due to the movement of the protective tube 14 inside the storage hole 103 can be prevented.

  In addition, since the power transmission line holding part 102 is formed of a plate-like member, it is small and lightweight, and furthermore, the work for inserting the protective tube 14 from the introduction port 104 and the introduction part 105 into the accommodation hole 103 is facilitated. Can do.

  Furthermore, in the power transmission line binding device 101, the two introduction parts 105 are arranged at the lower edge of the power transmission line holding part 102 and on both sides via the adapter 110, so that it is easy to balance during work and workability is improved. improves. In addition, there is an advantage that the common operation rod 201 can be easily attached to and detached from the adapter 110 of the power line binding device 101.

  FIG. 8 is a front view showing a modified example of the power transmission line binding device 101. In this example, the power transmission line holding unit 102 is formed in a trapezoidal shape, and two introduction ports 104 and two introduction parts 105 are provided on the lower edge of the power transmission line holding unit 102 and on both sides via the adapter 110. One piece is arranged on the upper edge of each part 102.

  FIG. 9 is a front view showing another modification of the power transmission line binding device 101. In this example, all of the three inlets 104 and the introduction part 105 are arranged at the lower edge of the power transmission line holding part 102. Two of them are arranged one on each side of the adapter 110. The remaining one has a step in the power transmission line holding portion 102 and is positioned above the two introduction ports 104 and the introduction portion 105 arranged on both sides of the adapter 110. According to the transmission line bundling device 101 illustrated in FIG. 9, all the inlets 104 face the same direction, and the direction is downward, so that the protective pipe 14 placed on the overhead power transmission line 13 is attached and detached. Work can be made easier.
