  The present invention includes a cutout body in which an accommodation space capable of accommodating a fuse is formed, an opening that is continuous with the accommodation space, and a lid that is attached to the opening of the cutout body. The present invention relates to a cylindrical cutout lid mounting tool.

  Conventionally, a cut-out for preventing abnormal power from being supplied to various devices is connected to an electric circuit to which various devices such as a transformer are connected. There are various types of such cutouts, and one of them is a cylindrical cutout. The cylindrical cutout is a cutout body 60 having a first end and a second end opposite to the first end, as shown in FIGS. 7 (a) and 7 (b). A cut-out body 60 in which a housing space (not shown) capable of housing a fuse (not shown) is formed, and an opening 600 continuous with the housing space is formed at the first end; A lid 61 configured to be detachable from the opening 600 of the main body 60, and a rope 62 connecting the cutout main body 60 and the lid 61 are provided.

  The cutout main body 60 includes a first connecting portion 601 for connecting the rope 62. The first connecting portion 601 is provided on the outer periphery of the first end portion of the cutout main body 60.

  The lid 61 includes a lid main body 610 that can be fitted into the opening 600 of the cutout main body 60, a cylindrical portion 611 that protrudes from the outer surface of the lid main body 610, and a second for connecting the cord 62. And a connecting portion 612. The second connecting part 612 is provided on the outer periphery of the cylindrical part 611.

  The first end portion of the rope 62 is connected to the first connection portion 601 of the cutout body 60. Then, the second end portion of the rope 62 is connected to the second connection portion 612 of the lid body 61. Thereby, the cutout main body 60 and the lid body 61 are connected by the rope 62.

  In the cylindrical cutout 6 having the above-described configuration, the fuse built in the cutout body 60 is electrically connected to the electric circuit on the upstream side in the power transmission direction and the electric circuit on the downstream side in the power transmission direction. In the cylindrical cutout 6 having the above configuration, when abnormal power is supplied from the upstream side in the power transmission direction to the downstream side in the power transmission direction, the fuse electrically connects the electric circuit on the upstream side in the power transmission direction and the electric circuit on the downstream side in the power transmission direction. It is designed to shut off.

  By the way, in the cylindrical cutout 6 having the above-described configuration, the lid 61 is removed from the cutout main body 60 by an indirect hot wire method when performing various operations such as fuse replacement work and maintenance / inspection work. In such various operations, the lid 61 is removed from the cutout main body 60 using an indirect hot-wire operation bar or an insulating jacket. When the work is completed, the lid body 61 is attached to the cutout main body 60 using an indirect hot wire operation rod. At this time, a lid attachment tool (hereinafter simply referred to as an attachment tool) of the cylindrical cutout 6 is attached to the distal end portion of the indirect hot wire operation rod.

  The mounting tool includes a base having a first end connected to the indirect hot wire operating rod and a second end opposite to the first end, and a base end connected to the second end of the base. And an insertion portion that is connected to the distal end portion of the arm and can be inserted into the cylindrical portion 611 of the lid body 61. The arm is provided in a fixed posture with respect to the indirect hot wire operating rod connected to the base. The insertion portion is disposed so as to extend in a direction intersecting with the axis of the indirect live-line operating rod connected to the base.

  And when attaching the cover body 61 to the cutout main body 60, the indirect hot wire operation stick | rod with which the attachment tool was attached is operated by the operator. Specifically, as described above, the lid 61 is provided with the second connecting portion 612 on the outer periphery of the cylindrical portion 611. Therefore, in a state where the lid body 61 is suspended from the cutout main body 60, the cylindrical portion 611 extends from the lid main body 610 in the lateral direction (mainly obliquely upward) (see FIG. 7B). ). Accordingly, with this type of mounting tool, the insertion portion is inserted into the cylindrical portion 611 after the insertion portion is brought into a posture capable of being inserted into the cylindrical portion 611 of the lid 61. In other words, the insertion portion is inserted into the cylindrical portion 611 after the posture is changed so as to be concentric with the cylindrical portion 611 of the lid 61 by the operation of the indirect hot wire operation rod by the operator.

  Thereafter, the direction in which the center line of the insertion portion extends (the insertion direction of the insertion portion with respect to the tubular portion 661) matches the attachment direction of the lid body 61 with respect to the cutout body 60 (the insertion direction of the lid body 610 with respect to the opening portion 600). As described above, the posture of the indirect live-line operation rod is changed. Thereby, the attitude | position of the cover body 61 is changed from the state which the cylindrical part 611 extended toward the horizontal direction (diagonal upper direction) to the state where the cylindrical part 611 extended toward the downward direction. And the cover body 61 is attached to the cutout main body 60 by moving the insertion part of an attachment tool upwards.

  By the way, the attachment tool of the said structure is extended in the direction which an insertion part cross | intersects with respect to the axial center of an indirect hot wire operation stick | rod as mentioned above. Therefore, in the mounting tool having the above-described configuration, the posture of the insertion portion is cut out from the posture in which the insertion portion can be inserted into the cylindrical portion 611 of the lid body 61 (or the posture inserted into the cylindrical portion 611 of the lid body 61). When changing to the posture corresponding to the mounting direction of the lid body 61 with respect to the main body 60 (the fitting direction of the lid main body 610 with respect to the opening portion 600), it is necessary to greatly change the posture of the indirect live-line operation rod.

  Furthermore, when using the attachment tool of the said structure, the base end part of the indirect hot wire operation stick | rod which was separated from the insertion part becomes an operator's operation position (gripping position). Moreover, the insertion part is extended in the direction which cross | intersects the axis line of an indirect hot wire operation stick | rod. Accordingly, the operator attaches the lid 61 to the cutout main body 60 (inserts the lid main body 611 into the opening 600 of the cutout main body 60), and the cutout main body 60 ( The lid 61 must be pushed up from the obliquely lower side of the opening 600). Therefore, it is difficult for the operator's force to be transmitted to the lid body 61, and it is difficult to attach the lid body 61 to the cutout body 60.

  Then, in view of such a situation, the present invention has an object to provide a cylindrical cutout lid attaching tool capable of improving the workability of the lid attaching operation to the cutout body in which the fuse is built. To do.

A lid attachment tool for a cylindrical cutout according to the present invention is a cutout body having a first end and a second end opposite to the first end, and can accommodate a fuse therein. A cutout body having an accommodation space formed therein, an opening continuous with the accommodation space formed at the first end, and a lid configured to be detachable from the opening of the cutout body. A cylindrical cutout lid mounting tool comprising a lid with a cylindrical portion projecting on the outer surface and a rope connecting the cutout main body and the lid, and an indirect hot wire operation rod is connected A base having a first end portion and a second end portion opposite to the first end portion, a base end portion rotatably connected to the second end portion of the base, and the base end portion An arm having a distal end on the opposite side, and an insertion that is connected to the distal end of the arm and can be inserted into the cylindrical part of the lid And parts, and a regulating locking mechanism the rotation of the arm insertion portion for indirect hot-line operation bar which is connected to the base in a state arranged in a row, the lock mechanism, the second end of the base A lock pin that is inserted into the arm and is slidable between the tip and the base end of the arm, and the indirect live wire operation rod and the insertion portion are in a line. A lock pin configured to be fitted into the notch, a biasing member that biases the lock pin toward the proximal end of the arm, and a cover body in which the arm is inserted and the lock pin is fixed And it is provided with the cover body which can be slid with a lock pin .

  With the cylindrical cutout lid mounting tool having the above-described configuration, when the operator rotates the arm, the insertion unit connected to the arm rotates together, and the posture of the insertion unit intersects with the indirect hot-line operation rod. The posture can be extended in the direction. Accordingly, the cylindrical cutout lid mounting tool having the above-described configuration can match the posture of the insertion portion to the posture of the cylindrical portion of the lid when attaching the lid to the cutout body. It can be easily inserted into the cylindrical part of the lid.

  And if an operator moves the front end side of an indirect hot wire operation rod below in the state where the insertion part was inserted in the cylindrical part of the lid, the insertion part will be caught in the cylindrical part of the lid. Accordingly, a rotational force acts on the insertion portion and the arm, and the insertion portion rotates together with the arm. As a result, in the cylindrical cutout lid mounting tool having the above-described configuration, the posture of the insertion portion is changed, and the insertion portion is in a line with respect to the indirect live-line operation rod connected to the base. In this state, the lock mechanism restricts the rotation of the arm with respect to the base. In other words, when the insertion portion is aligned with the indirect hot wire operation rod connected to the base, the insertion portion is fixed to the base while being maintained inserted in the cylindrical portion of the lid. The Accordingly, with the cylindrical cutout lid mounting tool having the above-described configuration, the posture of the insertion portion is inserted into the cylindrical portion of the lid without largely changing the posture of the indirect hot-wire operation rod. The posture can be changed from (or the posture inserted into the cylindrical portion of the lid) to the posture corresponding to the attachment direction of the lid with respect to the cut-out main body (insertion direction of the lid main body with respect to the opening).

  Then, by arranging the indirect live line operation rod so as to be aligned with the cutout body, the opening of the cutout body and the lid body are aligned with each other, so that the operator can connect the indirect live line operation rod. By pushing up from just below the lid, the lid can be attached to the cutout body. Therefore, the cylindrical cutout lid attaching tool having the above-described configuration can sufficiently transmit the operator's force to the lid, so that the lid can be easily attached to the cutout body.

As described above, with the cylindrical cutout lid mounting tool configured as described above, switching between the state in which the posture change of the insertion portion is restricted and the state in which the restriction on the posture change of the insertion portion is released is performed by a simple operation. Therefore, the efficiency of attaching the lid to the cutout body can be improved. In addition, according to the cylindrical cutout lid mounting tool configured as described above, when the insertion portion is aligned with the indirect hot wire operation rod connected to the base, the lock pin fits into the notch portion. Then, the rotation of the arm (change in the posture of the insertion portion) is restricted. On the other hand, when the lock pin is slid from the proximal end portion of the arm toward the distal end portion, the engagement of the lock pin with the cutout portion is released. As a result, the arm can be rotated again, and the insertion portion can change its posture. Therefore, the cylindrical cutout lid mounting tool having the above-described configuration can be switched between a state in which the posture change of the insertion portion is restricted and a state in which the restriction on the posture change of the insertion portion is released by a simple operation.

  In this case, the insertion portion has a first posture arranged in a line with respect to the indirect hot wire operation rod connected to the base by rotation of the arm, and the distal end portion of the insertion portion is more than the proximal end portion of the insertion portion. It is preferable that the posture can be changed between the second posture positioned on the side of the indirect live line operation rod. In this way, even if the cylindrical portion of the lid suspended from the cutout body extends obliquely upward, the posture of the insertion portion can be made to correspond to the posture of the cylindrical portion of the lid. . Therefore, the cylindrical cutout lid mounting tool having the above-described configuration can easily insert the insertion portion into the cylindrical portion extending obliquely upward.

  As described above, according to the lid attachment tool for a cylindrical cutout according to the present invention, it is possible to achieve an excellent effect that the workability of attaching the lid to the cutout body in which the fuse is housed can be improved. .
