  However, as shown in Patent Literature 1, when different types of indirect hot-line tools are accommodated in the same long tool storage bag, it is easy to appropriately select and remove a necessary indirect hot-line tool from the tool bag. Was not. In addition, there is a possibility that the indirect hot-line tools come into contact with each other in the long tool storage bag and the insulation performance of the indirect hot-line tool is impaired.

  In this regard, the invention related to the indirect hot-line insulated operating rod disclosed in Patent Literature 2 enables the indirect hot-line insulated operating rod to be hooked on a scaffold bolt of a utility pole by itself. Since it is assumed that a structural change is made to itself, there is an inconvenience that existing indirect hot-line tools cannot be used.

  In addition, the tool suspending tool disclosed in Patent Document 3 is shown as a tool for removing a handle and replacing it with an indirect hot-line tool that a handle of an operator can remove from an insulating rod. However, it cannot be said that it is compatible with existing indirect hot-line tools. Furthermore, a part on the hanging part side of the main body of the tool hanging tool cannot be moved with respect to other parts of the main body. Therefore, for example, in the case of a structure in which only the hooks provided directly on the main body of the hanging portion, it is not possible to adjust only the direction of the hooks of the hanging portion without changing the direction of the portion on the connecting portion side of the main body. In addition, there is a problem that the work of hooking the indirect live tool on the hooking target becomes complicated.

  Therefore, the present invention is to connect a connecting portion of an indirect hot-line tool to an existing indirect hot-line tool, such as a scaffold bolt of a utility pole or a horizontal bar of a movable body having a working floor of an aerial work vehicle. The main object of the present invention is to provide a connecting tool for an indirect hot-line tool, which can be hooked on a hooking object and can easily adjust the direction of a hooking mechanism on the hooking object.

  In order to achieve the above object, a connecting tool for an indirect hot-line tool according to the present invention includes a main body and a connecting portion provided on the main body and connected to a connecting portion of the indirect hot-line tool, A hooking mechanism is provided on a side opposite to the connecting portion of the main body, and has a hooking mechanism for hooking on a hooking object.The hooking mechanism is connected to the main body via a rotating shaft, and the rotating shaft is It is characterized by being rotatable with respect to the main body as an axis (claim 1). Examples of the tool for the indirect hot wire include a hot stick and an insulating plug.

  By connecting the connecting part of the connecting tool to the connecting part of the existing indirect hot-line tool, the existing indirect hot-line tool can be connected to the scaffold on the pole of the utility pole by using the hooking mechanism of the connecting tool. It can be hooked on a desired object to be hooked such as a bolt, an upper edge of a side surface of a bucket of an aerial work platform, an arm of a utility pole, or the like.

  And since the direction of the hooking mechanism of the connecting tool can be changed without moving the connecting portion of the indirect hot-line tool and the connecting tool connected thereto, the direction of the hooking mechanism can be easily hooked on the hooking target. This makes it easy to adjust so that the work for hooking the indirect hot-line tool can be simplified.

  In the connecting tool for an indirect hot-line tool according to claim 2, the hook mechanism includes a head having a tip portion having an inner peripheral surface capable of contacting an outer peripheral surface of the hooking target; A movable portion for holding the hooking target in a state where the outer peripheral surface is in contact with the inner peripheral surface of the portion. By using a hook-shaped hooking mechanism in this manner, even if both sides of the object to be hooked are connected to other members, such as a horizontal bar extending between the vertical pillars, the hooking is performed. It becomes possible to hook on the target.

  The connecting tool for an indirect hot-line tool according to claim 3, further comprising a second hooking mechanism attached to a head of the hooking mechanism and capable of hooking on a hooking object different from the hooking mechanism. It is characterized by: By having a plurality of hooking mechanisms capable of hooking on different hooking targets, it is difficult to select a hooking target on a pole of a power pole even when one connecting tool is connected to a tool for an indirect hot wire. Disappears.

  In the connecting tool for an indirect hot-line tool according to claim 4, a spherical joint is formed at a portion of the rotary shaft on a main body side end, and a spherical hole for accommodating the spherical joint of the rotary shaft in the main body. And a mounting hole having a tapered hole portion extending outward from the spherical hole portion is formed, and the spherical joint is received in the spherical hole portion of the mounting hole. Is pivotally connected to the main body part with the fulcrum as a fulcrum. In this way, the hooking mechanism can swing (tilt) in all directions with respect to the axial direction of the main body with the sphere joint accommodated in the main body as a fulcrum, thereby hooking the direction of the hooking mechanism. The work can be directed to the hooking object so that the work can be performed reliably and easily.

  In the connecting tool for an indirect hot-line tool according to claim 5, the hooking mechanism has an annular or U-shaped hooking rope. By using a hooking mechanism having such a hooking rope, when hooking a scaffold bolt or the like on an open hooking object, the hooking mechanism is not affected by the outer diameter and shape of the hooking object. It becomes possible to hook on the hanging object.

  As described above, according to the present invention, by connecting the connecting portion of the connecting tool to the connecting portion of the existing indirect hot-line tool, the existing indirect hot-line tool can be used as the hooking mechanism of the connecting tool. Utilizing it, it is possible to hook it on a desired object to be hooked such as a scaffold bolt on a pole of a utility pole, a side surface of a bucket of an aerial work platform, a metal arm of a utility pole, or the like.

  According to the present invention, the direction of the hook mechanism of the connecting tool can be changed without moving the connecting part of the indirect hot-line tool and the connecting tool connected to the tool. Since it is easy to adjust the direction of hooking to the target, it is possible to simplify the hooking work of the indirect hot-line tool to which the coupler is connected.

  In particular, according to the fourth aspect of the present invention, the hooking mechanism can swing (tilt) in all directions with respect to the axial direction of the main body with the spherical joint accommodated in the main body as a fulcrum. Since the direction of the hook mechanism can be adjusted to a more reliable and suitable direction by performing the hooking operation on the hooking target, the hooking operation of the indirect hot-line tool connected with the coupling tool is further performed. It can be simplified.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIGS. 1 to 3 show a connecting tool 1 according to a first embodiment as an example of a connecting tool (hereinafter referred to as a connecting tool) 1 for a tool for an indirect hot wire to which the present invention is applied. The connecting tool 1 is used by being temporarily connected to an indirect hot-line tool used for indirect hot-line work. The indirect hot-line tool includes, for example, a hot stick (also referred to as a common operation stick), an insulating yoke, and the like. First, as an example of the indirect hot-line tool, the hot stick 100 will be outlined with reference to FIG.

  The hot stick 100 shown in FIG. 2 includes a rod 101, a connecting portion 102 provided at a longitudinal end of the rod 101, and a connecting portion 103 provided at a longitudinal end of the rod 101. And is basically configured. The portion of the rod 101 closer to the distal end than the connection portion 103 is a handle for an operator to grip during the indirect hot-line operation.

  The connecting portion 102 has a substantially columnar outer shape, and has a columnar movable protrusion 102a on a distal end surface thereof. The movable protrusion 102a is attached to the connecting part 102 so as to be able to advance and retreat along the axial direction of the connecting part 102, and is moved in the protruding direction from the connecting part 102 by a spring (not shown) built in the connecting part 102. Being energized. Further, the connecting portion 102 is provided with a pair of locking projections 102b, 102b on the peripheral surface. These locking projections 102b, 102b have a columnar shape, and one of the locking projections 102b and the other of the locking projections 102b are connected at a position on the opposite side in the circumferential direction of the connecting portion 102. The portion 102 protrudes outward in the radial direction. In other words, one of the locking projections 102b and the other locking projection 102b project radially from a position 180 degrees out of phase.

  A portion of the rod 101 closer to the connection portion 103 than the connection portion 102 is provided with a flange 110 projecting from the outer peripheral surface of the rod 101 to the outside in the radial direction of the rod 101. A lock nut 111 that can move the outer peripheral surface of the rod 101 along the axial direction of the rod 101 is provided between the rod 102 and the part 102. Thus, by rotating the lock nut 111 in a predetermined direction, the connecting portion 102 and, for example, a connecting portion of a tip tool (not shown) can be securely fastened.

  The connecting portion 103 includes a substantially cylindrical tubular portion 105 having an opening 103a on the opposite side to the connecting portion 102 and having an internal space 104 communicating with the outside through the opening 103a. The inner space 104 has an inner diameter dimension into which the connecting portion 102 of the hot stick 100 and the connecting portion 20 of the connecting tool 1 described below can be inserted.

  In the cylindrical portion 105, a pair of slits 106, 106 are formed at positions substantially symmetric with respect to the center of the internal space 104 on the side of the opening 103a. These slits 106, 106 have a required dimension along the axial direction of the internal space 104 from the opening end of the opening 103a (for example, the same dimension as the dimension from the lock nut 111 side end of the connecting part 102 to the locking projection 102b). ) After the extension, it has a substantially T-shape extending along both sides of the cylindrical portion 105 in the circumferential direction. That is, the slit 106 is basically constituted by the slit portion 106a extending along the axial direction of the internal space 104 and the slit portion 106b extending along the circumferential direction of the tubular portion 105.

  As shown in FIG. 1, in the first embodiment, the connecting tool 1 according to the present invention includes a main body 10 and a connecting portion 20 connected to a connecting portion 103 of an indirect hot-line tool (such as a hot stick 100). , A flange 21, a lock nut 22, and a hooking mechanism 30. The configurations and functions of the connecting portion 20 (movable projection 20a, locking projection 20b), flange 21, and lock nut 22 of the connecting tool 1 are the same as those of the above-described connecting portion 102, flange 110, and lock nut 111 of the hot stick 100. Since it is the same, the description is omitted.

  The main body 10 of the connecting tool 1 is integrally formed with the flange 21, the lock nut 22 and the connecting portion 20, and is connected to the hooking mechanism 30 via a rotating shaft 25. In this embodiment, the hooking mechanism 30 is connected to the rotating shaft 25 so as to rotate integrally with the rotating shaft 25.

  In the first embodiment, as shown in FIG. 1, the hooking mechanism 30 includes a substantially C-shaped distal end portion 32, a base portion 33 facing the distal end portion 32, and a connecting portion 34 connecting the distal end portion 32 and the base portion 33. It has a configured head 31. The base 33 has an inclined portion 33 a having a width increasing from the connecting portion 34 toward the main body 10, thereby forming an inclined portion 33 a, and a flat portion provided at the most distal end surface of the distal end portion 32 and the inclined portion 33 a of the base 33. A predetermined opening S is provided between the upper surface of 33b and the side surface of the tip end.

  The hooking mechanism 30 has a movable part 40 for opening and closing the opening S between the tip of the tip part 32 and the upper surface of the flat part 33b of the base 33. In FIG. 1, the movable section 40 includes a plate-shaped section 41 and an elastic body 42. By filling the inside of the plate-like portion 41 with the elastic body 42 in this way, an obstacle enters the inside of the plate-like portion 41, and the plate-like portion 41 cannot move because the opening S is opened. Can be avoided. The plate-shaped portion 41 is rotatable about the shaft 36 as a shaft center, through which shafts 36 provided on the columns 35 provided on the flat portion 33b of the base 33 are inserted. In this embodiment, one of the elastic members 42 is connected to the inner surface of the plate-shaped portion 41, and the other is connected to the inclined portion 33 a of the base 33, and biases the plate-shaped portion 41 in a direction to close the opening S. It is supposed to. That is, the hooking mechanism 30 contracts toward the inclined portion 33a side of the base 33 from a state in which the elastic body 42 contracts due to, for example, a force of the operator holding the movable portion 40 and the plate-shaped portion 41 closes the opening S. However, when the pressing force on the plate-shaped portion 41 is removed, the plate-shaped portion 41 returns to the state in which the opening S is closed by the restoring force of the elastic body 42.

  Although not shown, the movable portion 40 of the hooking mechanism 30 is provided with a lock device on the back of the head 31, for example, at the back of the connecting portion 34, and unless the button of the lock device is pressed, the movable portion 40 opens the opening S. May not be moved in the opening direction. Although not shown, the movable portion 40 of the hooking mechanism 30 may have a stopper so that the plate-shaped portion 41 does not further rotate outward from the state in which the opening S is closed.

  The movable section 40 of the hooking mechanism 30 has various variations, and is not limited to the configuration of the movable section 40 shown in FIG. 1 and the like. As another example, although not shown, the movable portion 40 includes a long plate-shaped back portion, and a pair of plate-shaped facing portions extending substantially in parallel in the same direction from both edges along the longitudinal direction of the back portion. , The section may be substantially U-shaped. With such a configuration of the movable portion 40, the space S between the distal end portion 32 and the base portion 33 can be closed by the back portion, and the movable portion 40 is moved from the state in which the space S is closed to the head portion. The space S can be opened by rotating all or a part of the base portion 33 and the connecting portion 34 of the base 31 so as to be covered by a pair of facing portions. When the opening S is closed, the pair of opposing portions fills the space inside the opening S, so that an obstacle enters the inside of the opening S, and the movable portion 40 moves to open the opening S. Can be avoided. Further, the movable section 40 can be rotated so as to open the opening S by holding the facing section of the movable section 40.

  A process of attaching the connecting portion 20 of the connecting tool 1 having the above-described configuration to the connecting portion 103 of the hot stick 100 which is a kind of an existing indirect hot-line tool will be outlined with reference to FIGS. 1, 2 and 3. It is to be noted that the illustrated movable part 40 is an example of the movable part 40 applicable to the present invention, as described above.

  First, the lock nut 22 is turned to displace the lock nut 22 to the unlock position where the lock nut 22 contacts the flange 21, and in this state, the connecting portion 20 of the connecting tool 1 is inserted into the connecting portion 103 of the hot stick 100. At the same time, the locking projections 20b are inserted into the slit 106a of the slit 106. Next, the connecting portion 20 of the connecting tool 1 is axially pressed against the inner surface of the connecting portion 103 to sink the movable projection 20a of the connecting portion 20 against the elastic force of the built-in spring. By rotating the portion 20, the locking projection 20b is slid along the slit portion 106b. Then, by releasing the axial force of the connecting portion 20 and returning the connecting portion 20 in the axial direction by the urging force of the movable protrusion 20a, the locking protrusion 20b is formed at the tip of the slit portion 106b. The groove is irremovably engaged with the groove. Further, after these operations are completed, the lock nut 22 is rotated to displace the lock nut 22 to a lock position where the lock nut 22 is strongly contacted with the connection portion 103 of the hot stick 100, so that the connection tool 1 to the connection portion 103 is displaced. The attachment of the connecting portion 20 is completed.

  Next, a process of hooking the connecting tool 1 attached to an existing indirect hot-line tool such as a hot stick 100 on a rod 200 extending in a lateral direction shown as an example of a hooking target will be described with reference to FIG. Outline.

  After the direction of the indirect hot-line tool is turned upside down so that the connecting tool 1 is located upward, first, the plate-shaped portion 41 of the hooking mechanism 30 closes the opening S as shown in FIG. Is disposed at a position where the plate-shaped portion 41 (opening S) matches the rod 200. At this time, when the opening S of the hooking mechanism 30 is not facing the rod 200 side, the head 31 is rotated integrally with the rotating shaft 25 with respect to the main body 10 so that the opening S of the hooking mechanism 30 is Adjust so that it faces the 200 side. Next, as shown in FIG. 3A to FIG. 3B, the operator holds the movable portion 40 (the plate-shaped portion 41) and pushes the movable portion 40 with the hand of the worker, or pushes the movable portion 40 with the rod 200. Thus, a force that pushes the movable portion 40 inward is given. As a result, the plate-shaped portion 41 rotates about the shaft 36 as a rotation center, and the plate-shaped portion 41 is tilted to open the opening S. While the plate-shaped portion 41 in FIG. 3B is tilted and the opening S is opened, the stick 200 is operated to operate the hot stick 100 to which the connecting tool 1 is connected, so that the tip end portion 32 of the connecting tool 1 is moved. To the arcuate inner surface of. Then, with the rod 200 in contact with the arc-shaped inner surface of the distal end portion 32 of the connector 1, the force for pushing the movable portion 40 inward is released. Thereby, as shown in FIG. 3C, the movable portion 40 returns to the original state, and the hot stick 100 can be hooked on the rod 200 via the connector 1.

  Removal of the connecting tool 1 from the rod 200 is performed, for example, by pressing the movable part 40 to incline it toward the inclined part 33a, so that the state shown in FIG. 3C is changed to the state shown in FIG. After that, the opening S is removed from the rod 200.

  FIG. 4 shows a first modification of the coupler 1 shown in the first embodiment. 1 and the like are denoted by the same reference numerals, and description thereof is omitted. The connecting tool 1 shown in FIG. 4 has a holder 51 attached to these back sides from the connecting portion 34 to the base 33 of the head 31, a base attached to the holder 51, and a tip of the holder 51 having an inverted U-shape. The configuration further includes a second hooking mechanism 50 including the curved insertion portion 52. Thus, for example, by inserting the insertion portion 52 into a hole opened on the side surface of the arm (not shown), the indirect live wire tool can be hooked on the object other than the rod 200 (the arm (not shown) Money). Therefore, it is possible to increase the number of hooking targets that can be hooked by the indirect hot-line tool such as the hot stick 100 to which the connecting tool 1 is attached, and to indicate the hooking target that can be hooked on the pole of the telephone pole. You don't have to make a choice.

  FIG. 5 shows a modified example 2 of the coupler 1 shown in the first embodiment. The connecting device 1 shown in FIG. 5 is different from the first embodiment shown in FIG. 1 and the like. The spherical joint 26 is formed, and the mounting hole 11 for accommodating the spherical joint 26 is formed in the main body 10.

  The mounting hole 11 has a spherical hole portion 12 having a substantially spherical internal space, and a tapered hole portion 13 which is connected to the spherical hole portion 12 and gradually expands outward from the spherical hole portion 12 (toward the hooking mechanism 30). And The inner diameter of the spherical hole 12 is such that the spherical joint 26 can slide smoothly on the inner peripheral surface of the spherical hole 12 without rattling. The dimensions are such that the inner surface of the spherical hole 12 is in contact with the outer surface of the spherical joint 26 so that the spherical joint 26 does not move freely. The inside diameter of the connecting portion between the spherical hole portion 12 and the tapered hole portion 13 is smaller than the outer diameter of the spherical joint 26 so that the spherical joint 26 does not fall out of the mounting hole 11, while the rotary shaft 25 is inserted through the joint. In addition, it is slightly larger than the radial dimension of the rotating shaft 25 to such an extent that no rattling or slicking movement occurs when the rotating shaft 25 rotates.

  The rotating shaft 25 and the hooking mechanism 30 that moves integrally with the rotating shaft 25 can swing (tilt) in all directions in this embodiment, while a reference line along the axial direction of the main body 10. The tiltable angle with respect to L <b> 1 is until the rotation shaft 25 contacts the inner peripheral surface of the tapered hole portion 13 of the mounting hole 11 or the hook mechanism 30 contacts the main body 10. That is, when the hooking mechanism 30 and the main body 10 are connected by the rotating shaft 25, it is necessary that there is a certain gap between them.

  Thereby, the hooking mechanism 30 swings the head 31 in all directions with respect to the reference line L1 along the axial direction of the main body 10 with the spherical joint 26 accommodated in the main body 10 as a fulcrum. ) Is possible, so that only the hooking mechanism 30 can be tilted in a direction in which the opening S of the hooking mechanism 30 can be reliably and easily made by the rod 200.

  Although the spherical joint 26 is formed at the end of the rotating shaft 25 on the side of the main body 10 and the mounting hole 11 for accommodating the spherical joint 26 is formed in the main body 10, the hooking mechanism 30 and the hooking mechanism are not shown. 50 can also be used in the first modified example of the first embodiment having both of the first and second embodiments. By using the head 31 in the modification 1 of the first embodiment, the head 31 is set to the reference line so that the tip of the insertion portion 52 of the hooking mechanism 50 is oriented in a direction suitable for being inserted into the hole opened in the side surface of the arm. It can swing (tilt) with respect to L1.

  In the connection tool 1 shown in the first embodiment and the first and second modifications of the first embodiment, the inner diameter of the arc-shaped inner surface of the distal end portion 32 is adjusted to the diameter of the rod 200 to be hooked. Preferably there are a plurality of different types.

  FIG. 6 shows an example of Embodiment 2 of the connector 1 to which the present invention is applied. Hereinafter, the connector 1 of the second embodiment will be described with reference to FIG. However, the description of the same configuration and function as those of the coupler 1 of the first embodiment is omitted. Further, the process of mounting the connecting tool 1 of the second embodiment to the indirect hot-line tool such as the hot stick 100 is the same as that of the connecting tool 1 of the first embodiment, and therefore the description thereof is omitted.

  The connector 1 includes a main body 10, a plate-shaped pedestal 37 rotatably attached to the main body 10 via a rotation shaft 25, and an annular or substantially U-shaped hanging rope attached to the pedestal 37. And a hook mechanism 30 composed of That is, in the second embodiment, the connecting tool 1 has the hooking rope 38 instead of the head 31 and the movable portion 40 of the first embodiment as the hooking mechanism 30 of the second embodiment.

  With such a configuration of the connecting tool 1, for example, the hooking rope 38 constituting the hooking mechanism 30 is hooked on a hooking object whose tip such as a scaffold bolt on a pole of a utility pole (not shown) is opened. It is possible to hook a tool for an indirect hot wire (hot stick 100 or the like) via the connecting tool 1. In addition, since the structure of the hooking mechanism 30 can be simplified, manufacturing costs can be reduced, and it is not necessary to prepare a plurality of connecting tools 1 according to the diameter of the hooking target.
