Description

  The present invention relates to an operating rod made of an insulating material suitable for indirect hot-wire work, and in particular, extends the overall length by connecting to the base end of a standard shared operating rod equipped with an indirect hot-wire tool such as an insulating Yatco or a tip tool. It is related with the structure of the operation rod for the extension used for this purpose.

  When using an indirect hot wire tool in indirect hot wire work, in order to be able to work from a remote location on a live wire member such as a high-voltage overhead wire, the joint bracket of the indirect hot wire tool For example, it is generally performed to connect an attachment main body of a common operation rod extending linearly as shown in Patent Document 1, for example. When rotating the common operation rod, as shown in Patent Document 1, the operator holds the vicinity of the base end of the common operation rod with both hands and holds the common operation rod with the axis of the common operation rod. The operation of rotating many times as the center of rotation was performed.

  However, when an operator rotates the shared operation rod with both hands holding the part near the base end of the shared operation rod that extends in a straight line, the operator's hand slides, etc. May be difficult to transmit, or it may be difficult to increase the rotation speed of the common operation rod, which may result in insufficient tightening of the object. In this case, it is conceivable that the base end side of the common operation rod can be bent with respect to the axial direction of other portions of the common operation rod, and the bent side is used as a handle.

  In this respect, as an auxiliary tool for an insulating operation bar that assists the connection between the insulating operation bar and a tip tool attached to the distal end of the insulating operation bar, for example, as shown in Patent Document 2 and the like, It is provided with a tip tool side connecting portion, and the operating rod side connecting portion and the tip tool side connecting portion are connected via a connecting means, and are connected to the operating rod at an angle of about 90 degrees via a Kiza seat adapter. An auxiliary tool for an insulating operation rod that can be used is already known.

  The connecting means for connecting the operating rod side connecting portion and the tip tool side connecting portion of the insulated operating rod auxiliary tool shown in Patent Document 2 is composed of an operating rod side structure and a tip tool side structure. . The operation rod side structure includes a cylindrical body, a slide rod, and a tray member, and the tip tool side structure includes a cylindrical body having an opening, and a rod and a rod inserted into the cylindrical body from the opening. It has a spherical body provided at the tip of the body. Furthermore, the saucer member of the operating rod side structure can be viewed from the spherical body of the tip tool side structure, and the inner diameter dimension of the opening of the cylindrical body is smaller than the outer diameter dimension of the spherical body, The required width is larger than the outer diameter dimension of the rod body. With this, in a state where the rod body is displaced so as to be inclined with respect to the axial direction of the opening portion, The operating rod side connecting portion and the tip tool side connecting portion are connected to the tip tool by pressing the body and the receiving plate portion and fitting the convex portion of the spherical body with the concave portion of the receiving plate portion. It will be connected and fixed in the state displaced with respect to the axis of a side connection part.

  In addition, the mechanism that can connect the auxiliary tool for the insulating operation rod and the operation rod shown in Patent Document 2 at an angle of 90 degrees via the Kikuza adapter is the receiving portion of the operation rod side structure. The opposite end is provided with a Kikuza structure, which is structured to be able to mesh with the Kikuza structure of the Kikuza adapter. And the Kikuza adapter has the attachment main body which can be connected with the joint metal fitting of an insulation operating rod on the opposite side to the side which has the Kikuza structure part.

  But in the structure of the connection means which connects the operation-bar side connection part of the auxiliary tool for insulation operation bars shown in the said patent document 2, and the front-end tool side connection part, the rod body of a front-end tool side connection part is the operation-bar side. Since it cannot be displaced, for example, at an angle of 90 degrees with respect to the axis of the connecting portion, even if this connecting means is adopted as an insulating operating rod, the operating rod side connecting portion can be easily used as a handle for the operator to grip. Not.

  In addition, the mechanism that can connect the auxiliary tool for the insulating operation rod and the operation rod shown in Patent Document 2 at an angle of 90 degrees requires a Kikuza adapter in addition to the auxiliary tool for the insulating operation rod. Therefore, the number of parts increases, and the operation for connecting the Kikuza structure part of the operating rod side structure and the Kikuza structure part of the Kikuza adapter is not always easy.

  Furthermore, even with the insulating operation bar auxiliary tool disclosed in Patent Document 2, in order to rotate an indirect live tool such as a common operation bar to which the insulating operation bar auxiliary tool is connected, the insulating operation bar auxiliary tool is used. In order to make the remote operation suitable after connecting the insulation operation rod auxiliary tool and the insulation operation rod, it is necessary to rotate the shaft center of the insulation operation rod auxiliary tool many times. In addition, it is impossible to adjust the total length of the assembly composed of the auxiliary tool for the insulating operation rod and the insulating operation rod.

  Accordingly, the present invention provides an angle formed by separating a bar body of an insulating operation bar from one bar body member into the other bar body member, and forming one rod body member and the other bar body member. An object of the present invention is to provide an insulating operating rod that can be displaced in a range from a right angle to an obtuse angle and that is also easy to displace the angle. Further, the present invention can rotate the indirect live tool to which the insulating operation rod is connected without having to rotate the axis of the insulating operation rod about the axis of the insulation operation rod as a rotation center. Another object of the present invention is to provide an insulating operation rod capable of changing the dimension along the axial direction of the rod body of the insulating operation rod in order to make the operation suitable.

  The insulating operation rod according to the present invention includes a rod body made of an insulating material, and the rod body includes a first rod body component member and a second rod body component member, and the first rod body configuration. One end side of the member and one end side of the second rod member constituting member are connected by a connecting mechanism, and the connecting mechanism is provided on the one end side of the first rod member constituting member. A direction in which the meshing structure, the second meshing structure provided on one end side of the second rod-constituting member, and the first meshing structure and the second meshing structure are in contact with each other The first meshing structure has at least an arcuate circumferential surface, and a plurality of protrusions are arranged radially on the circumferential surface, and the second meshing structure. The body has an arcuate circumferential surface capable of contacting at least the arcuate circumferential surface of the first meshing structure, and the circumferential surface A plurality of indentations are arranged radially so as to be able to mesh with the projections of the first meshing structure, and the projections of the first meshing structure and the depressions of the second meshing structure The angle formed by the first rod member and the second rod member can be varied in a range from a right angle to an obtuse angle. 1). The insulating operation rod may be, for example, an extension rod connected to the common operation rod, the common operation rod itself, or a rod portion that is a part of an indirect live tool such as an insulation tool. good. In the case where the insulating operation rod is, for example, an extension rod connected to the common operation rod or a common operation rod, the first rod member is, for example, a rod member on the side having the attachment body, This rod member is, for example, the rod member on the side having the joint fitting. However, the first rod member may be a rod member on the side having the joint fitting, and the second rod member may be the rod member on the side having the attachment body.

  As a result, the first bar constituting member and the second bar constituting member constituting the rod body of the insulating operation rod are separated from the protrusion of the first meshing structure body of the coupling mechanism and the second rod body by a predetermined procedure. The position where the indented portion of the meshing structure meshes with each other can be displaced, and as a result, the angle formed by the first rod member and the second rod member can be varied from a right angle to an obtuse angle. From the above, when the first bar constituting member of the insulating operating rod is connected to the common operating rod, the force is applied when the second rod constituting member of the insulating operating rod is grasped by any of the workers' hands. It is possible to rotate the common operation rod by making the handle portion easy to add. In addition, since the angle formed by the first rod member and the second rod member can be adjusted in a range from a right angle to an obtuse angle, the first rod member and the second rod Even in a narrow working environment where it is difficult to make the angle formed by the body component members at right angles, it is easy to apply force when the second rod member of the insulating operation rod is grasped with any hand of the worker. It can be a handle portion.

A protrusion that can be inserted into the cutout portion of the first rod member is provided, and the protrusion has an arcuate peripheral surface in which the recess is disposed. A linear spring that is possible, and the second rod from the first rod-constituting member side of the spring. The direction extending toward the rod-constituting member is variable so as to match the position where the protrusion of the first meshing structure and the recess of the second meshing structure are meshed with each other (claim 2). ). The linear spring that can be expanded and contracted is, for example, a coil spring, and this also applies to the spring shown in claim 3.

  As a result, the first bar constituting member and the second bar constituting member constituting the rod body of the insulating operation rod pull the second meshing structure body and the protrusions of the first meshing structure body. After the meshing with the recess of the second meshing structure is released, the second meshing structure is rotated in a required direction along the circumferential direction of the circumferential surface of the first meshing structure, and then the second By stopping the pulling of the meshing structure, the first meshing structure of the coupling mechanism is re-engaged with the protrusion of the first meshing structure and the recess of the second meshing structure. The position where the protrusion of the body and the recess of the second meshing structure mesh with each other is displaced, and as a result, the angle formed by the first rod component and the second rod component is changed from a right angle to an obtuse angle The range can be varied. Therefore, it is possible to easily perform an operation for changing the angle formed by the first rod member and the second rod member from a right angle to an obtuse angle.

  Further, in the insulating operating rod according to the present invention, the first meshing structure extends along the axial direction of the first rod-constituting member to a portion on one end side of the first rod-constituting member.

Provided with a projecting portion that can be inserted into the cutout portion of the first rod component member, and has an arcuate peripheral surface in which the recess portion is disposed on the projecting portion, The elastic mechanism has a linear spring that can be expanded and contracted, and the first rod structure of the spring One end is aligned so that the direction extending from the material side to the second rod-constituting member side is aligned with the position where the protrusion of the first meshing structure and the recess of the second meshing structure mesh. The first engagement structure is connected to the engagement structure main body, and the other end is connected to the peripheral surface of the second rod-constituting member (Claim 3).

  Thereby, the 1st rod body constituent member and the 2nd rod body constituent member which constitute the bar body of an insulation operation rod are the projection of the 1st meshing structure, and the hollow part of the 2nd meshing structure. By rotating the first meshing structure while meshing with each other, the position where the projection of the first meshing structure of the coupling mechanism and the recess of the second meshing structure mesh with each other is displaced. The angle formed by the first bar-constituting member and the second bar-constituting member can be varied from a right angle to an obtuse angle. Therefore, it is possible to easily perform an operation for changing the angle formed by the first rod member and the second rod member from a right angle to an obtuse angle.

  On the other hand, in the insulating operation rod according to the present invention, the rod body is provided with a ratchet mechanism at a portion in the middle of the longitudinal direction, and the portion located on one side with the portion having the ratchet mechanism as a boundary. By swinging at a relatively small angle, the part located on the other side can be rotated with the part having the ratchet mechanism as a boundary. Of the rod bodies, the ratchet mechanism may be provided on the first rod member or the second rod member.

  As a result, when the rotation is transmitted from the insulation operation rod to the indirect live tool such as the common operation rod or the tip tool thereof, the first rod body component member of the insulation operation rod has the part having the ratchet mechanism as a boundary. It is only necessary to swing the part located on one side at a relatively small angle with respect to the part located on the side or the part having the second rod member constituting member ratchet mechanism.

  First, as shown in FIG. 3A, the rod member 22 is held slightly in the direction of the arrow in FIG. 3A along the axial direction of the rod member 22 with the grip portion 7. move. As a result, the coil spring 121 is extended in a manner that resists the urging force. As shown in FIG. 3B, the protrusion formed on the peripheral surface 101 a of the meshing structure 10 and the meshing structure 11. Engagement with the depression formed in the peripheral surface 111 is released.

As shown in FIG. 3 (c), the axis of the rod component member 21 and the axis of the rod component member 22 are perpendicular to each other in the surrounding direction and along the peripheral surface 101a of the meshing structure 10. To be. At this time, since the rotating shaft 122 also rotates in the same direction and at the same rate in accordance with the movement of the rod member 22, the extending direction of the coil spring 121 that connects the rotating shaft 122 and the meshing structure 11 is also the rod body. This is perpendicular to the axis of the component 21.

  Further, as shown in FIG. 3C, the pull of the rod member 22 is loosened in a state where the axis of the rod member 21 and the axis of the rod member 22 are at right angles. As a result, the engagement structure 11 of the rod member 22 approaches the engagement structure 10 of the rod member 21 as indicated by the arrow in FIG. 3C due to the biasing force (restoring force) of the coil spring 121. It will be done.
