  However, in order to perform a series of operations such as pulling the wire coating stripping tool on the overhead wire and stripping the sheath of the overhead wire, a shared operation with an indirect live wire gripping tool such as Quick and a bind hitter installed as a tip tool There is a need for a different type of indirect live tool, a bar. For this reason, at the time of transporting the tool for indirect hot-wire to the work site, inconvenience and inconvenience occurred in a temporary storage place at the work site. In addition, it is necessary to change the indirect hot line tool during the operation, to operate by a plurality of workers, or to hold the indirect hot wire tool in both hands by one worker.

  In addition, in order to turn the engagement ring of the wire coating stripping tool to bring the blade for stripping the overhead wire away from the overhead wire, the hook of the bind punch is inserted into the through hole of the engagement ring. There is also a problem that the base part may enter the through hole of the engagement ring, and the engagement ring may not be able to be rotated well with the bind hammer.

  Furthermore, as shown in Patent Document 1, the wire coating stripping tool is generally arranged such that the axis of the screw rod having the engagement ring at the tip and the axis of the arm intersect at 90 degrees. Therefore, when the entire wire coating stripping tool is rotated around the overhead wire in order to strip off the coating of the overhead wire, there is also a disadvantage that the wire coating stripping tool cannot be rotated well.

  Therefore, the present invention can perform a series of operations of pulling the wire coating stripping tool over the overhead wire with one type of indirect live wire tool and stripping off the coating of the overhead wire. When used, the problem of causing a problem in inserting the engagement ring into the through hole is fundamentally solved, and the operation of rotating the wire to remove the wire covering can be smoothly performed. The purpose is to provide a collection device.

  The overhead wire sheath stripping device of the present invention is an overhead wire sheath stripping device for stripping the sheath of the overhead wire formed by covering the periphery of the core wire with an insulating coating, and can contact the side surface of the overhead wire. The holding part in which the concave part is formed, the blade holder that is close to the holding part, and the blade body holder that bites only into the covering of the overhead wire that contacts the concave part of the holding part when the blade holder is closest to the holding part. The blade attached to the blade holder and extending away from the holding portion, and the end on the holding portion side is attached to the blade holder so that the blade holder is attached to the holding portion. A screw rod that is movable in the direction of distance, and a base portion that is provided on a side facing the recess with respect to the holding portion and has a threaded insertion hole through which the screw rod can be inserted. Take the blade holder A gripped portion that can be sandwiched and gripped by a pair of gripping portions of an indirect live wire gripping tool is provided at the opposite end to the gripped side, and the blade holder side is closer to the gripped portion. And a gripping part for rotating the whole wire stripping stripping device around the axis of the overhead wire as a center of rotation by the gripping part of the indirect live wire gripping tool. It is characterized in that it can be rotated about the axis of the center of rotation (claim 1). The indirect hot-wire gripping tool is, for example, a quick type insulating jacket.

  As a result, in the indirect hot wire operation, the screw rod is removed to lift the overhead wire stripping device and hook the holding portion on the overhead wire or to bring the blade holder of the overhead wire stripping device closer to the holding portion. In both the rotating operation and the operation of lifting the overhead wire stripping device and rotating it around the overhead wire, the gripping portion of the screw rod is held by a pair of holding portions of the same indirect live wire gripping tool. It is possible to do so.

  In the overhead wire stripping device of the present invention, the gripping part is disposed at the annular part, a pair of rod-like parts extending radially outward from the annular part, and the distal ends of the stick-like parts in the extending direction. And a gripping part body gripped by a pair of gripping parts of the indirect live wire gripping tool, and the annular part is formed closer to the blade holder than the gripped part of the screw rod. In addition, the screw rod is extrapolated to a small-diameter portion having a smaller outer diameter than other portions of the screw rod (claim 2).

  As a result, when the gripping part is difficult to rotate the sheathing stripping device around the overhead line because the direction of the pair of rod-shaped parts protruding from the annular part is not parallel to the axial direction of the overhead line The gripping part main body of the gripping part is gripped by a pair of gripping parts of an indirect live wire gripping tool, the annular part is rotated, and the direction of the pair of rod-like parts protruding from the annular part is parallel to the axial direction of the overhead wire It is possible.

  In the wire stripping stripping device of the present invention, the annular portion of the grip portion has an outer diameter smaller than an outer diameter of a portion other than the small-diameter portion of the screw rod, and the rod-shaped portion An engaging portion is formed on the side facing the screw rod, and the screw rod has a contact surface that can contact the annular portion on the outer peripheral side of the small diameter portion, and further from the contact surface. Further, a plurality of engaging portions that can engage with the engaging portion of the rod-shaped portion are formed radially on the outer peripheral side with the small diameter portion as a base point (claim 3).

  As a result, when the gripping part main body of the gripping part is gripped by the pair of gripping parts of the gripping tool for indirect live wire and the gripping part is rotated in order to rotate the wire stripping stripping device around the overhead line, the gripping part Since the ring-shaped portion is securely engaged with the screw rod, the grip portion can be easily turned.

  In the overhead wire sheath stripping device of the present invention, the holding portion is formed with an arm extending coaxially with respect to the extending direction of the screw rod and in a direction opposite to the screw rod, A pair of rod-shaped portions extending radially outward from the arm, and a grip portion main body disposed at the distal ends of the rod-shaped portions in the extending direction and gripped by the pair of gripping portions of the indirect live wire gripping tool And a gripping part constituted by the following: (Claim 4).

  As a result, the screw rod having the gripping portion at the tip and the arm having the gripping portion are arranged in opposite directions with the overhead line as the center. Since the arm comes down by its own weight, both the gripping parts are positioned more than the case where the screw rod having the gripping part at the tip and the arm having the gripping part are shifted by 90 degrees about the overhead line. It is possible to use the overhead wire covering stripping device when the overhead wire stripping device is rotated around the overhead wire.

  As described above, according to the overhead wire stripping device according to the present invention, in an indirect hot-wire operation, the operation of lifting the overhead wire stripping device and hooking the holding portion on the overhead wire, or stripping the overhead wire Both the operation to rotate the screw rod to bring the blade holder of the instrument closer to the holding part and the operation to lift the cable stripping removal instrument and rotate it around the overhead line are the same as the gripped part of the screw bar. It can be performed by sandwiching and gripping with a pair of gripping portions of the indirect live wire gripping tool. For this reason, a series of operations for lifting the overhead wire stripping device and rotating it around the overhead wire can be performed with one indirect live wire gripping tool, so that a plurality of indirect live wire gripping tools can be stored. It is not necessary to store the indirect live wire gripping tool in the middle of work, operate the two indirect live wire gripping tools with both hands, or perform the series of operations by two people.

  Moreover, in the operation of rotating the threaded rod to move the blade holder of the wire stripping stripping tool away from the holding portion, it is not necessary to insert the hook of the bind hammer into the through hole of the threading ring of the threaded rod and turn it. Therefore, there is no problem that the hook of the bind hammer enters the threaded hole of the threaded engagement ring to the base.

  Particularly, according to the overhead wire stripping device according to the invention of claim 2, when the screw rod is rotated in the direction approaching the holding portion, and the blade body is appropriately brought into contact with the overhead wire, the grip portion If the direction of the pair of rod-shaped parts protruding from the annular part is not parallel to the axial direction of the overhead wire, the grip part main body of the grip part is gripped by the pair of gripping parts of the indirect live wire gripping tool. By rotating the part, the direction of the pair of rod-shaped parts protruding from the annular part can be made parallel to the axial direction of the overhead wire. For this reason, it is possible to easily perform an operation of rotating the overhead wire covering stripping tool around the overhead wire without being restricted by the rotational speed of the screw rod.

  Particularly, according to the overhead wire stripping device according to the invention of claim 3, in order to rotate the overhead wire sheath stripping device around the overhead wire, the grip portion main body of the grip portion is paired with a pair of indirect live wire gripping tools. When gripping with the gripping part and turning the gripping part, the gripping part's annular part is securely engaged with the screw rod, so that the gripping part can be easily rotated, so the operation of the wire stripping stripping device It is possible to improve the property.

  In particular, according to the overhead wire stripping device of the invention of claim 4, the screw rod having the grip portion at the tip and the arm having the grip portion are arranged in opposite directions with the overhead wire as the center. For this reason, since the screw rod having the grip portion at the tip and the arm having the grip portion are arranged in opposite directions with the overhead line as the center, when the screw rod is turned above the horizontal, the arm is lowered below the horizontal. Since the arm comes down by its own weight, both the gripping portions are made to be more than the case where the screw rod having the gripping portion at the tip and the arm having the gripping portion are shifted by 90 degrees about the overhead line. Utilizing it, it is possible to successfully rotate the overhead wire stripping device when rotating the overhead wire stripping device around the overhead wire, so that the operability of the overhead wire sheath stripping device can be further improved. Is possible.
