  However, when the presser part of the presser device shown in Patent Document 1 has an optimum shape for sandwiching the upper part of a sleeve cover such as a jumper sleeve cover, a high pressure as shown in FIG. With respect to the underline connector cover, it is difficult to securely pinch the upper portion of the insulating cover between the U-shaped top portion and the spread portion of the holding portion of the holding fitting without rattling. For this reason, when the connector cover is brought close to the overhead wire, the use of a cover pressing device having an optimal shape for sandwiching the upper portion of the sleeve cover may cause the connector cover to fall. Therefore, when using a cover presser device that has an optimal shape for holding the upper part of the sleeve cover, the insulation cover other than the sleeve cover is placed close to the overhead line and placed on the overhead line with an insulating jacket. There is a need.

  Even when the insulation cover other than the sleeve cover is placed close to the overhead wire and placed on the overhead wire, even when the insulation cover is held by the insulation cover, the operator can grasp the operation lever to Since the movable gripping piece swings and the gripping part of the insulating cover is gripped by the fixed gripping piece and the movable gripping piece, if the operator's gripping force on the operation lever is loosened for any reason, the insulating cover There is also a risk of falling off and falling.

  On the other hand, even if the insulating cover is a sleeve cover and the pressing portion of the pressing device has an optimum shape for sandwiching the upper portion of the sleeve cover, the inverted U-shaped top portion and the spreading portion of the pressing portion are referred to. Since the sleeve cover is only clamped from above by the bracket, it cannot be said that clamping the sleeve cover is necessarily stable, and when the presser device is moved closer to the overhead wire with the sleeve cover attached, the sleeve cover comes off from the presser part. There is a risk of falling.

  Therefore, the present invention can deal with a plurality of types of insulating covers attached to the overhead wire, and can securely hold the insulating cover so that it can be brought close to the overhead wire in a stable state. It is an object of the present invention to provide an apparatus for attaching an insulating cover overhead wire that makes it easy to release the holding of the insulating cover and can easily attach the insulating cover to the overhead wire.

  An insulated cover overhead wire mounting apparatus according to the present invention is an insulated cover overhead wire mounting apparatus for mounting an insulating cover having a pair of cover structural members and the cover structural member opening downward. A pressing portion for pressing the pair of open cover components in the closing direction by contacting the upper portion of the insulating cover from above; and any one of the cover components of the pair of cover components A clamping mechanism for clamping the lower part, and the positional relationship between the pressing part and the clamping mechanism is such that when the pressing part comes into contact with the upper part of the insulating cover, the clamping mechanism Located below the lower part of the component member, and when the clamping mechanism clamps the lower part of the cover component member, a gap is provided between the pressing portion and the upper part of the insulating cover. Is characterized by being adapted occurs (claim 1). The overhead line is, for example, an underline, a high-voltage distribution line, or the like. The insulating cover is, for example, various sleeve covers, underline connector covers, and the like.

  Thus, with respect to the insulating cover in a state where the lower part of the pair of cover constituent members is opened, the lower part of one cover constituent member is first clamped by the clamping mechanism of the insulating cover overhead wire mounting device, and the insulating cover is brought close to the overhead wire. After the overhead wire is positioned at a required position between one cover constituent member and the other cover constituent member of the insulating cover, the insulation cover overhead wire mounting device is displaced downward, so that the presser portion Abuts against the upper part of the insulating cover from above, and further pushes both of the pair of cover components in the closing direction, so that the insulated cover overhead wire mounting device of the present invention is mainly used to install the insulated cover in the opened state. A series of operations including the operation of approaching and the operation of closing the insulating cover can be performed. In addition, the lower part of the insulating cover is held between the upper part of the insulating cover and not the upper part of the insulating cover until it is placed on the overhead line. In this state, the insulating cover can be brought close to the overhead wire. And only by displacing the insulation cover overhead wire mounting device downward, the clamping mechanism is displaced downward from the lower part of the insulating cover and the lower part of the insulating cover is released. The work for removing the part is not necessary.

  More specifically, with respect to the insulated cover overhead wire mounting apparatus according to the present invention, the presser portion includes two contact portions for contacting the upper portion of the insulating cover and pressing it from two directions, and the two contact portions. The holding mechanism includes a first holding member that is fixedly connected to the support portion of the pressing portion, and a shaft holder portion that is connected to the bearing holder portion of the first holding member. A second holding member that is swingably attached to the first holding member, one end is connected to the first holding member, and the other end is connected to the second holding member. The second clamping member has a clamping part for clamping the lower part of the cover component member with the first clamping member extending from the shaft part, and An operation for moving the clamping part closer to the lower part of the cover component. The portion extends from the shaft portion in a direction different from the extending direction of the clamping portion, and the operation portion is urged in a direction in which the gripping portion is close to the first clamping member, It is connected with the other end of the elastic mechanism (Claim 2). The elastic mechanism is, for example, a coil spring.

  Thereby, the first clamping member of the clamping mechanism comes into contact with the lateral outer surface of the cover constituent member, the clamping part of the second clamping member of the clamping mechanism comes into contact with the mating surface of the lower part of the cover constituent member, and Since the holding portion of the second holding member is pressed toward the first holding member by the elastic mechanism of the holding mechanism, the lower portion of the insulating cover is held between the first holding member and the holding portion of the second holding member. It can be securely clamped.

  Here, the insulated cover overhead wire mounting device according to the present invention is an insulated cover overhead wire mounting device configured to have two each of the holding portion and the holding mechanism, and each of the two holding mechanisms. An extension part extending from the receiving part of the first clamping member to be configured to the opposite side of the clamping part, and a base part disposed between the clamping mechanisms, and a first part of the extension part An end opposite to the clamping member side of 1 is fixed to the base, and a connecting portion for connecting to the connecting portion of the indirect hot wire tool is provided on the side opposite to the side where the extending portion of the base is fixed. (Claim 3). The indirect hot-line tool shown here is a common operation stick etc., for example.

  Thereby, while being able to use the apparatus for attaching an insulating cover overhead wire as a tip tool of an indirect hot wire tool, it can be clamped at two locations by two clamping mechanisms with respect to the lower portion of the insulating cover. In a stable state, the insulating cover can be brought close to the overhead wire and placed on the overhead wire.

  In the insulated cover overhead wire mounting apparatus according to the present invention, the operation part of one second clamping member and the operation part of the other second clamping member constituting the two clamping mechanisms are integrated. In addition, the operation portion is provided with a grip portion that can be gripped with an indirect live tool (Claim 4). The indirect hot wire tool shown here is an indirect hot wire tool for gripping, such as an insulating Yatsuko, for example.

  As a result, when the second clamping member swings in the direction in which the second clamping member of the two clamping mechanisms moves away from the first clamping member, the operation parts of the two clamping mechanisms are shared by one. As a result, the operation of swinging the two second holding members can be performed simultaneously.

  Here, the insulated cover overhead wire attaching device according to the present invention is an insulated cover overhead wire attaching device configured to have one each of the holding portion and the holding mechanism, wherein the holding mechanism constitutes the holding mechanism. A connecting portion for an indirect hot wire tool having an extending portion extending from the receiving portion of the first holding member to the side opposite to the holding portion, and the side of the extending portion opposite to the first holding member side And a connecting portion for connecting to the head. (Claim 5).

Since the overhead wire can be positioned, the work to move the insulation cover to the overhead wire in a stable state and place it on the overhead wire while using the apparatus for attaching the insulated cover overhead wire of the present invention mainly Is possible.
Next, at the stage of closing the cover constituent member of the insulating cover, the presser part comes into contact with the upper part of the insulating cover from above by displacing the device for attaching the insulating cover overhead wire downward. Since both are pushed in the closing direction, it is possible to perform the operation of closing the lower part of the pair of cover components of the insulating cover while mainly using the apparatus for attaching the insulating cover overhead wire of the present invention, and to attach the insulated cover overhead wire. To disengage the lower part of the insulating cover, the holding mechanism is displaced downward from the lower part of the insulating cover and the lower part of the insulating cover is released. This work can be made unnecessary.

In particular, according to the second aspect of the present invention, the first clamping member of the clamping mechanism is brought into contact with the lateral outer surface of the cover constituent member, and the clamping part of the second clamping member of the clamping mechanism is placed under the cover constituent member. Since the urging force that presses the gripping portion of the second clamping member toward the first clamping member by the elastic mechanism of the clamping mechanism is applied to the side portion mating surface, the lower portion of the insulating cover is The first holding member and the holding portion of the second holding member can be securely held.
Further, by operating the operation part of the second clamping member, the clamping part of the second clamping member can be swung in the direction away from the first clamping member, so that the lower part of the cover component member is When holding, the holding part is tilted in a direction in which the tip of the holding part is separated from the first holding member by holding the operation part, and the holding part and the first holding member are provided on both sides of the lower part of the cover constituent member. When the position of the cover member is located, the lower part of the cover constituent member can be sandwiched between the sandwiching part and the first sandwiching member by using the biasing force of the elastic mechanism by separating the operation part. Become.

  In particular, according to the third aspect of the invention, since the connecting portion for connecting with the connecting portion of the indirect hot wire tool is provided, the insulating cover overhead wire mounting device according to the present invention is used as a tip tool of the indirect hot wire tool. Since it has two clamping mechanisms, the lower part of the insulation cover can be clamped at two locations, so the work until the insulation cover is brought closer to the overhead wire and placed on the overhead wire in a more stable state. It is possible to prevent the accident that the insulating cover falls.

  In particular, according to the invention described in claim 4, when the second clamping member swings in a direction in which the clamping part of the second clamping member of the two clamping mechanisms is away from the first clamping member, Since the operation part of the mechanism is made common to one, it is possible to simultaneously perform the operation of swinging the two second holding members, so the lower part of the insulating cover is attached to the insulating cover overhead wire of the present invention. The work of holding by the holding mechanism of the device for use can be simplified.

  In particular, according to the invention described in claim 5, it is possible to use the insulating cover overhead wire mounting device as a tip tool of an indirect hot wire tool, and the shape of the insulating cover overhead wire mounting device becomes relatively small. It is possible to use the device for attaching an insulating cover overhead wire according to the invention even in a place where the working environment is narrow.

  Next, the process of attaching the insulating cover 100 to the overhead wire 200 using the insulation cover overhead wire attaching apparatus 1 having such a configuration will be described with reference to FIGS. 3 and 4.

  First, after attaching the connecting portion of the common operation rod 300 to the connecting portion 5, the gripping portion 6 is gripped by an insulating jacket (not shown), and the operating portion 32 c is pushed toward the inclined portion 31 b side of the sandwiching member 31 for clamping. The portion 32b is separated from the standing portion 31a of the sandwiching member 31, that is, the sandwiching portion 32b and the standing portion 31a of the sandwiching member 31 are opened, and the sandwiching portion 32b and the standing portion 31a of the sandwiching member 31 are covered. With respect to the cover 100 in a state where the constituent member 101 and the cover constituent member 102 are opened downward, the cover member 102 and the cover constituent member 102 are arranged on both sides with respect to the outer surface and the mating surface of the lower part of the cover constituent member 102.

  Next, the insulating yoke is removed, and the lower portion of the cover constituent member 102 is clamped by the clamping portion 32 b and the standing portion 31 a of the clamping member 31 by the urging force of the coil spring 33. At this time, the contact portions 21 and 22 of the presser portion 2 are not in contact with the upper portion of the insulating cover 100, and a gap is opened with a required dimension.

In order to be able to contact with certainty, after extending diagonally from the shaft portion 32a along the radial direction, it is linearly extended straight upward, as shown in Example 1. It is the same as the holding member 32 to be held.

  On the other hand, as shown in FIG. 5, the shaft portion 32 a has one cylindrical shape so as to be shared by the clamping member 32 included in one clamping mechanism 3 and the clamping member 32 included in the other clamping mechanism 3. Along with this, it is pivotally supported by the bearing holder portions 31 c of both of the two clamping members 31. In addition, the operation portion 32c is configured so that the shaft portion 32a extends from the shaft portion 32a so as to be lower than the inclined portion 31b of the holding member 31 when the holding portion 32b is positioned above the inclined portion 31b of the holding member 31. Is the same as that of the first embodiment in that it extends linearly along the radial direction and is substantially L-shaped with the clamping portion 32b. However, as shown in FIG. And the clamping member 32 of the other clamping mechanism 3 are integrated into one plate. And the grip part which can be gripped with an indirect live tool for gripping such as an insulating jacket at the tip in the extending direction from the shaft part 32a at the intermediate part between the sandwiching part 32b and the sandwiching part 32b of the operation part 32c 1 is included. This gripping portion 6 is provided so as to extend downward when the operation portion 32c is oriented in the horizontal or nearly horizontal direction so that it can be easily gripped from below with a gripping indirect live tool such as an insulated jacket.

One end of the coil spring 33 is outside the inclined portion 31 b of the clamping member 31 as in the first embodiment. While being connected to a side surface (a side surface opposite to the sandwiching portion 32b), the other end is coupled to an upper surface of the operation portion 32c of the sandwiching member 32 (a side surface of the inclined portion 31b of the sandwiching member 31). The coil spring 33 also urges the operation portion 32 c away from the inclined portion 31 b, that is, the direction in which the clamping portion 32 b is close to the standing portion 31 a of the clamping member 31.

  Although not shown, the shaft portion 32a and the operation portion 32c included in the clamping member 32 of each clamping mechanism 3 are not shared between the two clamping mechanisms 3 and 3 and are the same as described in the first embodiment. In addition, the clamping member 32 may be provided separately with the shaft portion 32a and the operation portion 32c.

  And the extension part 4 extended toward the lower side from the bearing holder part 31c of both clamping members 31, respectively is provided, and the lower end of this extension part 4 is connected with the base part 7. ing. That is, the base part 7 is constructed so as to extend between the two clamping mechanisms 3 and 3. And the connection part 5 for connecting with the connection part of the common operation rod 300 shown by FIG. 6, FIG. 7 through the columnar member 71 on the opposite side in which the extension part 4 of the base part 7 was provided. Is provided.

  Next, the process of attaching the insulating cover 100 to the overhead wire 200 using the insulation cover overhead wire attaching apparatus 1 having such a configuration will be described with reference to FIGS. 6 and 7.

  First, after attaching the connecting portion of the common operation rod 300 to the connecting portion 5, the gripping portion 6 is gripped by an insulating jacket and the operation portion 32 c is pushed toward the inclined portion 31 b side of the sandwiching member 31. The sandwiching portion 32b and the standing portion 31a of the sandwiching member 31 are opened. Thereby, it is possible to operate the two clamping parts 32b with one insulating jacket.

  For any of the sandwiching portions 32b and the standing portion 31a of the sandwiching member 31, the outer surface of the lower portion of the cover constituent member 102 with respect to the insulating cover 100 with the cover constituent member 101 and the cover constituent member 102 open. Arrange it on both sides of the mating surface.

  Further, the insulating yoke is removed, and the lower portion of the cover constituting member 102 is held between the holding portion 32 b and the standing portion 31 a of the holding member 31 by the urging force of the coil spring 33. At this time, the lower part of the cover constituent member 102 is sandwiched at two places. Further, the contact portions 21 and 22 of the presser portion 2 are not in contact with the upper portion of the insulating cover 100 and are in a state where a gap is opened with a required dimension.

  Furthermore, as shown in FIG. 6, the insulated cover overhead wire mounting device 1 is installed while the lower part of the cover component member 102 is sandwiched between the clamping part 32 b and the standing part 31 a of the clamping member 31 at two locations. 200, and further, as shown in FIG. 7A, the overhead line 200 is formed at a required position between the cover constituent member 101 and the cover constituent member 102, that is, the insulating cover 100 is connected to the overhead line 200. The insulation cover overhead wire attaching device 1 is appropriately displaced in the left-right direction or the like so as to be on the board.

  Finally, as shown by the white arrow in FIG. 7A, the insulation cover overhead wire mounting device 1 is displaced downward. Thereby, after each contact part 21 and contact part 22 of two presser parts 2 contact the upper part of insulating cover 100, each contact part 21 and contact part 22 are cover constituent members. Since 101 and 102 are continuously pressed toward the center in the width direction of the insulating cover 100 from above, the lower part of the cover constituent members 101 and 102 is further closed. Further, since the clamping portion 32b of the clamping member 32 of the clamping mechanism 3 is displaced below the lower part of the cover constituent members 101 and 102, the lower part of the cover constituent member 102 is also clamped by the clamping mechanism 3. Canceled. When the insulation cover overhead wire mounting device 1 is displaced downward, the gripping portion 6 is gripped by the insulating jacket and the operation portion 32c is pushed toward the inclined portion 31b side of the sandwiching member 31, so that the sandwiching portion 32b and the sandwiching member 31 are The standing portion 31a may be in an open state, whereby the holding of the lower portion of the cover constituent member 102 by the holding mechanism 3 is more smoothly released.

  According to the above, also in the insulating cover overhead wire mounting apparatus 1 shown in the second embodiment, the clamping portion 32b is biased by the coil spring 33 between the standing portion 31a of the clamping member 31 of the clamping mechanism 3 and the clamping portion 32b of the clamping member 32. Since the lower part of the cover constituent member 102 of the insulating cover 100 sandwiched between the two can be sandwiched by pressing it against the upright portion 31a, the insulating cover 100 can be securely sandwiched and the insulating cover 100 can be securely sandwiched. It is possible to prevent the insulation cover 100 from coming off and falling when the insulation cover overhead wire attaching device 1 is brought close to the overhead wire 200 and the insulation cover 100 is put on the overhead wire 200 in a state where the insulation cover 100 is sandwiched. Become.

  In addition, in the insulating cover overhead wire mounting apparatus 1 shown in the second embodiment, the insulating cover 100 can be sandwiched at two locations, so that the insulating cover 100 is a pull-down connector cover and has a protrusion 105 at the center in the longitudinal direction. Even if it has, it is possible to avoid this protrusion part 105 and to clamp. Further, even when the insulating cover 100 is a sleeve cover such as a high-pressure branch sleeve cover that does not have a protruding portion, the insulating cover 100 can be clamped at two locations, so that the insulating cover 100 can be brought close to the overhead wire 200 in a stable state. Can be done.

  In addition, since the insulating cover overhead wire mounting apparatus 1 is configured to clamp the lower portion of one cover component member with the clamping mechanism 3 rather than from above with respect to the insulating cover, the upper edge is in the horizontal direction. Even in a high-pressure tension clamp cover that extends obliquely, the lower portion of one cover component of the clamp cover can be clamped by the clamping mechanism 3 of the insulation cover overhead-line mounting device 1. It is possible to use it for the work which approaches 200 and gets on overhead line 200.
