Description

  The present invention relates to an indirect hot wire tip tool used when attaching an electric wire cover or an insulating sheet to an electric wire in an indirect hot wire operation, and an indirect configuration in which the indirect hot wire tip tool is attached to an indirect active gripping tool. The present invention relates to a live work tool.

  Conventionally, in indirect hot wire work in which an electric wire cover or insulating sheet is attached to an electric wire, the electric wire cover or insulating sheet is gripped by using an indirect hot wire gripping tool called an insulating Yatsuko and approached to the electric wire in that state. I was trying to install it.

  As shown in FIG. 7, the indirect live-line gripping tool 100 has a pair of operating portions 102 a and 102 b on the distal end side of the main shaft 101, and a pair of gripping portions 103 a and 103 b provided at the distal ends of the operating portions. Is opened and closed by an operation unit 104 provided on the base end side of the main shaft 101.

  The operation unit 104 includes a handle 105 rotatably attached to the base end side of the main shaft 101, and has a structure in which the handle 105 is connected to one operating unit 102a by a connecting rod 106. The handle 105 is constantly urged in the direction of expansion by a coil spring 107 attached to the support shaft 105a, and the connecting rod 106 is pressed when the handle 105 is pushed and narrowed against the urging force of the coil spring 107 (handle). 105 is rotated so as to be close to the main shaft 101), and the base end portion of one of the operating portions 102a is pulled. The one actuating part 102a is rotatably attached to the other actuating part 102b by a support shaft 108. When the handle 105 is turned against the coil spring 107, the base end part of the actuating part 102a is provided. Is pulled by the connecting rod 106, and the gripping portion 103a moves toward and contacts the gripping portion 103b of the other operating portion 102b.

Further, when the handle 105 is released from the handle 105 and the handle 105 is returned to the original position by the spring force of the coil spring 107, the one end of the actuating portion 102a is pushed out by the connecting rod 106 with respect to the support shaft 108. The grip part 103a is separated from the grip part 103b of the other operation part 102b.
Therefore, the pair of grip portions 103a and 103b are opened and closed by an operation of gripping the handle 105 and an operation of releasing the grip (see, for example, Patent Document 1).

JP 2009-50053 A

  However, when gripping an electric wire cover or insulating sheet with such an indirect live wire gripping tool (insulating YATCO), the gripping portions 103a and 103b are narrow, so the electric wire cover or insulating sheet must be gripped only at one point. Therefore, the gripping position is easily shifted and it is difficult to perform stable work. For this reason, the electric wire cover and the insulating sheet have fallen off or cannot be operated as expected, and it has been necessary to return to the hand and start the operation again.

  In addition, when an indirect activation operation is performed using an insulating jacket in an operation of connecting an electric wire (for example, a high-voltage underline) to the sleeve, the electric wire is gripped only at one point. Skill was required in the work to insert and the work to hold firmly the state inserted in the metal sleeve, and workability was poor.

  The present invention has been made in view of such circumstances, and is configured by stabilizing the gripped state and capable of avoiding falling off and the like, and an indirect live wire gripping tool attached to the indirect live wire gripping tool. The main task is to provide an indirect hot wire working tool.

  In order to achieve the above object, an indirect live wire tip tool according to the present invention is attached to each of a pair of gripping portions provided at a tip portion of an indirect live wire gripping tool. A head portion provided, a Kikuza adapter integrally formed with a joint portion attached to the gripping portion, a base end portion provided with a Kikuza portion that meshes with the Kikuza seat portion of the Kikuza adapter, and the A gripping tool in which a plurality of gripping arm portions branched from a base end portion in a plurality of (for example, bifurcated) and whose distal end portion extends on the opposite side of the base end portion are integrally formed. It is characterized by.

  Moreover, the indirect hot wire working tool which concerns on this invention is the indirect hot wire working tool comprised by attaching the indirect hot wire tip tool which makes a pair to the holding part which makes the pair provided in the front-end | tip part of an indirect hot wire holding tool. Each of the indirect hot wire front end tools includes a head portion provided with a chrysanthemum portion, a chrysanthemum adapter in which a joint portion attached to the gripping portion is integrally formed, and a chrysanthemum of the chrysanthemum adapter. A base end portion having a chrysanthemum seat portion that meshes with the seat portion, and a plurality of (for example, bifurcated) branches from the base end portion, and the tip end portion is extended to the side opposite to the base end portion. And a gripping tool in which a plurality of gripping arm portions are integrally formed.

  Therefore, each indirect hot wire distal end tool is composed of a Kikuza adapter and a gripping tool attached to the adapter so that the angle can be adjusted, and the gripping tool is branched into a plurality of parts so that the distal end is opposite to the base end. Since it has a plurality of extended gripping arm sections, when gripping an object to be gripped, such as an electric wire cover or an insulation sheet, each indirect hot wire is adjusted after adjusting the mounting angle of the gripping tool. The plurality of gripping arm portions of the tip tool can be opposed to the plurality of gripping arm portions of the other indirect hot wire tip tool, and the object to be gripped can be sandwiched therebetween. For this reason, it is possible to sandwich the object to be grasped at a plurality of positions after adjusting the grasping direction of the object to be grasped, and it is possible to form a stable grasping state.

In the above-described configuration, the plurality of gripping arm portions of the gripping tool of each of the indirect live wire tip tools are formed symmetrically with respect to the base end portion, and the respective tip end portions of the plurality of gripping arm portions of the gripping tool In addition, a non-slip member may be provided.
In such a configuration, it becomes easier to hold the gripped state, and the gripped state can be strengthened.

  Here, the anti-slip member may be configured by making its surface non-flat. For example, the surface may be uneven, or the intermediate portion may be recessed to curve the surface. With such a configuration, it is possible to stabilize the gripped state even when gripping not only the sheet-like object to be gripped but also the electric wire.

  The indirect live-line gripping tool is always urged in the direction in which the paired gripping parts are separated from each other, and is operated by operating the operating unit provided on the terminal side of the indirect live-line gripping tool (gripping In other words, the distance between the gripping portions may be changed. Even when such an operation unit uses an indirect live wire gripping tool far from the gripping unit, a stable gripping state can be obtained by operating the operation unit when using the above-described pair of indirect live wire tip tools. It becomes.

As described above, according to the present invention, the pair of indirect live wire tip tools attached to the gripping portion forming the pair of indirect live wire gripping tools can be attached to the head portion and the gripping portion provided with the chrysanthemum portion. A Kikuza adapter configured with a joint portion, and a plurality of gripping arm portions attached to the Kiza seat adapter so that the angle can be adjusted, and having a distal end portion extending on the side opposite to the base end portion. Since it has a gripping tool, the joint part of the Kikuza adapter of each indirect live wire tip tool is attached to the gripping part of the indirect live wire gripping tool, and the angle of the gripping tool is adjusted with respect to the Kiza seat adapter. If the gripping parts of the indirect live gripping tool are brought close to each other in this state, it becomes possible to sandwich the object to be gripped by the plurality of gripping arm parts of the respective gripping tools, and the gripped state can be stabilized. Possible, omission It is possible to stop.
In addition, since the gripping tool can be fixed by adjusting the angle of the gripper adapter, it is not necessary to work in an unreasonable posture, and it is possible to work in a stable posture.
Furthermore, it is possible to further stabilize the gripping state by providing a plurality of gripping arm portions of the gripping tool symmetrically with respect to the base end portion and attaching a non-slip member to the distal end portion of each gripping arm portion. Become.

Fixing the state (engagement state of the chrysanthemum part 33 of the chrysanthemum adapter 3 and the chrysanthemum part 41 of the gripping tool 4), the base end part 42 of the gripping tool 4 can be connected at a desired mounting angle. Yes. Therefore, the gripping tool 4 is coupled so as to have a desired mounting angle only on the plane on which the chrysanthemum part 33 of the chrysanthemum adapter 3 is formed.

  As shown in FIG. 3, the gripping tool 4 is bifurcated from the base end portion 42 provided with a base seat portion 41 that meshes with the base seat portion 33 of the star base adapter 3 and the base end portion 42. The distal end portion is formed by integrally forming a pair of gripping arm portions 44 extending on the side opposite to the base end portion 42.

  The base end portion 42 is formed with a Kikuza portion 41 that engages and engages with the Kikuza portion 33 of the Kikuza adapter 3 on a flat surface. This Kikuza part 41 has a well-known configuration, and forms a notch 41a along the axial direction from a flat base end and extends radially around the notch 41a from the central part. The plurality of protrusions 41b are arranged in a ring shape at a predetermined interval.

  Each of the gripping arm portions 44 is formed integrally with the base end portion 42 and is substantially orthogonal to the extending direction of the base end portion 42 and is in a direction opposite to the other gripping arm portion 44. The distal end portion 44 a is extended to the side opposite to the base end portion 42 by being bent at a substantially right angle from the terminal end thereof. The base end portion 42 and the pair of gripping arm portions 44 are formed on substantially the same plane, and the axis of the base end portion 42 (the center extending through the center of the base end portion 42 in the extending direction of the base end portion).
