[Configuration of stray link tongs]
First, prior to describing the indirect hot-wire tool adapter 1 according to an embodiment of the present invention, the stray link tong 100 to which the indirect hot-wire tool adapter 1 is attached will be described.

  4 is a side view showing the appearance of the stray link tongue 100, FIG. 5 is a perspective view showing the front end portion of the stray link tongue 100, and FIG. 6 is a side view showing the front end portion of the stray link tongue 100. As shown in FIG. 4, the stray link tongue 100 includes a tip tool 110 corresponding to an indirect hot wire tool provided on the tip side, and a long insulating operation rod 150 having insulating properties.

  The tip tool 110 includes a fixed portion 112 and a movable portion 114 that moves so as to advance and retreat in the axial direction of the insulating operation rod 150.

  As shown in FIG. 5, the fixing portion 112 includes a main body 116, a rotating body 117, and a knob portion 118.

  The main body 116 includes a claw-shaped distal end portion 120, a central portion 123 extending from the proximal end side of the distal end portion 120, and a proximal end portion extending from the end portion of the central portion 123 in the same direction as the distal end portion 120 extends. 124 is a substantially U-shaped member. A circular through hole 124a (see FIG. 6) is formed in the approximate center of the base end portion 124.

  The rotating body 117 is a substantially cylindrical member that is inserted into the through-hole 124 a of the base end portion 124, and a thread groove is formed on the inner peripheral surface of the rotating body 117. The outer diameter of one end of the rotator 117 is formed larger than the diameter of the through hole 124 a, and the one end of the rotator 117 is disposed inside the substantially U shape and faces the tip 120. A gear 136 having an outer diameter larger than the diameter of the through hole 124a is connected to the other end of the rotating body 117. As a result, the rotating body 117 is supported so as to be detached from the main body 116 and to be rotatable independently of the main body 116.

  The knob portion 118 is provided in front of the base end portion 124, and restricts the unlocked state in which the rotating body 117 is rotatable with respect to the main body 116 and the right rotation of the rotating body 117 with respect to the main body 116 by the operation of the operator. On the other hand, it is switched to a locked state that allows left rotation.

  The movable part 114 is a movable part that can hold (grip) the electric wire in cooperation with the fixed part 112 and a rod-shaped screw shaft body 130 that is threaded so as to mesh with the thread groove on the inner peripheral surface of the rotating body 117. And a body 132. The movable body 132 has a shape in which the long side portion of one of the rectangular side surfaces is formed in an isosceles trapezoid, and is a member thicker than the fixed portion 112. The movable body 132 is disposed so that the isosceles trapezoidal portion faces the fixed portion 112. The movable body 132 has a concave portion 132a on the surface facing the central portion 123 of the fixed portion 112, and is rotatably attached to the distal end portion of the screw shaft body 130 with the concave portion 132a fitted in the central portion 123. It has been. In addition, the fixing portion 112 includes a knob portion 118 that is a part of a lock mechanism that holds the electric wire so that it is not easily loosened when the electric wire is tightened.

  A gear 136 is fixed to the tip of the insulating operation rod 150 as shown in FIG. In addition, a space that can be stored when the screw shaft body 130 of the movable portion 114 is retracted is formed at the distal end portion of the insulating operation rod 150. Further, in order to prevent an electric shock accident in the indirect hot wire operation, a safety limit collar 152 is provided in the middle of the insulating operation rod 150. This is provided in order to clarify the boundary between a portion that does not receive an electric shock even when the operator grips it and a portion that does not receive an electric shock and a portion that does not receive an electric shock when gripped. Further, the insulation operation rod 150 is provided with a draining collar 154 in the middle of the safety limit collar 152 from the tip side of the insulation operation rod 150 as a measure against rain.

  Next, a method of using the stray link tongue 100 will be described with reference to FIGS. First, the degree of opening between the distal end of the distal end portion 120 of the fixed portion 112 and the distal end of the movable body 132 of the movable portion 114 is adjusted to such an extent that an electric wire can be inserted. Then, holding the insulating operation rod 150, the tip tool 110 is brought close to the electric wire, the electric wire is passed through the gap 140 between the tip of the tip 120 of the fixed portion 112 and the tip of the movable body 132 of the movable portion 114, and the tip 120 Hang on. When the insulation operating rod 150 is rotated in this state, a force is applied to the fixing portion 112 so that the electric wire is twisted with the distal end portion of the distal end portion 120 and the proximal end portion of the distal end portion 120 as contacts, and the fixing portion 112 rotates. Stopped. Then, when the insulating operation rod 150 is further rotated, since the fixed portion 112 is prevented from rotating, the rotating body 117 that is rotatably attached to the base end portion 124 rotates. On the other hand, in the movable portion 114, since the rotating body 117 rotates, a rotational force is applied to the screw shaft body 130 screwed into the through hole 124 a of the rotating body 117 and the movable body 132 fixed to the screw shaft body 130. On the other hand, the concave portion of the movable body 132 is fitted into the central portion 123 of the fixed portion 112, and the movable body 132 is prevented from rotating.

  Therefore, when the insulating operation rod 150 is rotated counterclockwise, the fixed portion 112 is prevented from rotating by the electric wire, and the movable body 132 is prevented from rotating by the fixed portion 112, so that the rotating body 117 rotates counterclockwise. When the rotating body 117 rotates counterclockwise, the screw shaft body 130 moves toward the tip portion 120, and the movable body 132 moves toward the tip portion 120 together with the screw shaft body 130. Thereby, the clearance gap 140 becomes narrow and the electric wire hooked on the front-end | tip part 120 can be clamped. Further, when the insulating operation rod 150 is rotated to the right, the fixed portion 112 is prevented from rotating by the electric wire and the movable body 132 is prevented from rotating by the fixed portion 112, so that the rotating body 117 rotates to the right. When the rotating body 117 rotates to the right, the screw shaft body 130 and the movable body 132 are retracted toward the insulating operation rod 150 by the screw of the screw shaft body 130, and the gap 140 is widened. In addition, although mentioned later for details, when it is set to the locked state by operation of the knob part 118, the clockwise rotation of the insulation operation stick | rod 150 is controlled. In other words, the wire can be loosened in the unlocked state.

  Further, the electric wire is tightly tightened by the distal end portion 120 and the movable body 132 by hooking the electric wire on the distal end portion 120 of the fixed portion 112 and rotating the insulating operation rod 150 counterclockwise. Thereby, the electric wire is held by the stray link tong 100.

  Here, the stray link tong 100 has a function of locking the backward movement of the movable portion 114 so that the tightened electric wire does not loosen easily. That is, as shown in FIG. 5, a ring-shaped gear 136 is fixed to the tip of the insulating operation rod 150. The gear 136 is connected to the fixed portion 112 and has irregularities arranged in the circumferential direction. The unevenness has a smooth slope on the surface facing when the insulating operation rod 150 is rotated counterclockwise, and the surface facing when the insulating operation rod 150 is rotated clockwise is a substantially vertical surface. The knob portion 118 includes a protrusion (not shown) that protrudes toward the gear 136, and is attached so as to be movable toward the unevenness of the gear 136. Then, when the knob portion 118 is moved to the insulating operation rod 150 side, that is, to the lower side and the insulation operation rod 150 is rotated to the right, the protrusion of the knob portion 118 comes into contact with the substantially vertical surface of the unevenness, and the insulation operation rod 150 right rotations are limited. Thereby, the backward movement of the movable body 132 is limited. On the other hand, when the insulating operation rod 150 is rotated counterclockwise, it comes into contact with the smooth inclination of the unevenness, but can easily get over along the inclination, so the left rotation of the insulating operation rod 150 is not limited. That is, in the locked state in which the knob portion 118 is moved downward, the left rotation of the insulating operation rod 150 is allowed and the right rotation is restricted. Thereby, the movable body 132 can advance. Further, in the unlocked state in which the knob portion 118 is moved to the distal end portion 120 side of the fixed portion 112, that is, the knob portion 118 is moved upward, the protrusion of the knob portion 118 does not come into contact with the unevenness. Is also acceptable.

  The indirect hot-wire tool adapter 1 includes a fixed adapter 10 that is fixed to the distal end portion 120 of the fixed portion 112 and a movable adapter 30 that is fixed to the movable body 132 of the movable portion 114. For convenience of the following description, in the axial direction of the insulating operation rod 150 of the stray link tongue 100, the tip tool 110 side is referred to as the upper side or the upper side, and the side gripped by the operator is referred to as the lower side or the lower side. In addition, the direction perpendicular to the axial direction of the insulating operation rod 150 of the stray link tongue 100 and the gap 140 of the fixing portion 112 in the tip tool 110 is directed to the front or front side, and the opposite direction of the front or front side is the rear or rear side. Called. Further, when the gap 140 of the fixing portion 112 in the tip tool 110 is viewed from the front, the left hand side with respect to the fixing portion 112 is referred to as the left side or the left side, and the right hand side with respect to the fixing portion 112 is referred to as the right side or the right side. It is assumed that the vertical direction, the front-rear direction, and the left-right direction are perpendicular to each other.

  As shown in FIG. 2, the fixed adapter 10 includes a fixed adapter body 12 that sandwiches the tip of the fixed part 112, and a fixed adapter that extends from the fixed adapter body 12 to the tip of the fixed part 112, that is, forward. A head portion 14 and a fixing screw 16 are provided. Here, the front end portion of the fixing portion 112 in the stray link tongue 100 is assumed to indicate a portion above the front end of the fixing portion 112.

  The fixed-side adapter main body 12 has a front part 12a and a pair of gripping pieces 12b and 12b that extend from both side parts of the front part 12a and are bent at the front end part. The fixed-side adapter main body 12 is formed in a C shape when viewed in plan (the insulating operation rod 150 is viewed in the axial direction). The area surrounded by the C-shape is substantially equal to the shape of the fixed portion 112 in plan view. For this reason, the fixed-side adapter main body 12 is configured to be able to cover the distal end portion 120 of the stationary portion 112 and sandwich the distal end portion 120 between the pair of gripping pieces 12b and 12b.

  Moreover, the fixed side adapter head part 14 is extended from the upper part of the front part 12a, and a pair of holding piece is extended in the opposite direction with respect to the extension direction of the fixed side adapter head part 14, ie, back.

  On the surfaces of the pair of gripping pieces 12b, 12b, fixing screws 16 are attached to the left and right sides at three locations, respectively. Then, the fixed adapter 10 is fixed to the fixed portion 112 by covering the fixed adapter body 12 with the distal end portion 120 of the fixed portion 112 and tightening the fixed portion 112 from both sides with the fixing screw 16. In this state, the tip portions of the pair of grip pieces 12b, 12b are located on the opposite side of the portion of the fixing portion 112 that faces the tip of the fixing portion 112, that is, on the rear side. The tip ends of the pair of gripping pieces 12 b and 12 b are connected by a hook 18.

  The hook 18 includes a slightly warped metal member 18a having a leaf spring property and an engagement piece 18b that engages with the metal member 18a. One end of the metal member 18a is rotatably fixed to the surface of the tip of one gripping piece 12b, and the other end is formed in a bowl shape. The engaging piece 18b is fixed to the surface of the distal end portion of the other gripping piece 12b.

  Then, after the fixed adapter body 12 is placed on the tip of the fixing portion 112 and fixed by the fixing screw 16, the metal member 18a is rotated and engaged with the engaging piece 18b of the other gripping piece 12b. As a result, the fixed adapter 10 is fixed to the fixing portion 112. In a state where the fixed adapter 10 is fixed to the fixed portion 112, the fixed adapter head portion 14 extends forward from the tip of the fixed portion. The distal end of the fixed adapter head portion 14 is disposed above the distal end of the fixed portion 112.

  As shown in FIG. 2, the movable adapter 30 includes a movable adapter fixing part 32, a movable adapter jaw part 34, and a lock pin 36.

  The movable adapter fixing portion 32 is a portion fixed to the movable portion 114 and includes a pair of gripping pieces 38 and 38, a coil spring 40, a support shaft 42, and a stopper 44.

  The movable adapter jaw portion 34 is a member that extends from the movable adapter fixing portion 32 and faces the fixed adapter head portion 14 of the fixed adapter 10.

  The lock pin 36 is a member for locking the movable adapter fixing portion 32 so as not to be detached from the movable portion 114.

  Specifically, the movable adapter jaw portion 34 includes a substantially rectangular base portion 34a extending in the left-right direction, a holding piece 34b extending forward from the center portion and both end portions in the longitudinal direction of the base portion 34a, and the length of the base portion 34a. It is comprised from the protrusion part 34c which protrudes in a rectangular parallelepiped shape back from the center part of a direction. The base part 34 a is set longer than the width of the movable part 114. The holding piece 34b has a tip end that is curved in an arc shape, and a central portion that is formed into a rough surface as a slip stopper. The protruding portion 34c is formed slightly shorter than the width of the movable portion 114, and the movable side adapter fixing portion 32 is attached to the protruding portion 34c.

  A hexagonal columnar through hole (not shown) extending in the left-right direction is formed in the protruding portion 34c. The support shaft 42 is inserted into the through hole. At this time, the support shaft 42 protrudes from both ends in the left-right direction of the protrusion 34c. Since the support shaft 42 is a hexagonal rod-shaped member, the support shaft 42 can slide with respect to the protrusion 34c, but cannot rotate. A pair of grip pieces 38 are slidably attached to both ends of the support shaft 42.

  The gripping piece 38 is made of a plate-like member that covers a region on the side surface of the movable portion 114 excluding the concave portion 132a that engages with the central portion 112b of the fixed portion 112. Further, the gripping piece 38 has a rectangular shape when viewed from the side, and the upper part of one gripping piece 38 is formed in an L shape. Furthermore, a hexagonal through hole (not shown) is formed on the front side of the gripping piece 38 on the surface facing the movable portion 114.

  FIG. 3 is a plan view when the movable-side adapter fixing portion 32 shown in FIG. 2 is viewed from below. The support shaft 42 is inserted into the through hole of the protrusion 34c, the coil spring 40 is inserted into both ends of the support shaft 42 protruding from both sides of the protrusion 34c, and the support shaft 42 is inserted into the through hole of the gripping piece 38. The One end of each of the two coil springs 40 and 40 is fixed to the protruding portion 34 c, and the other end of the coil spring 40 is fixed to the gripping piece 38. As a result, the movable adapter fixing portion 32 is attached to the movable adapter jaw portion 34.

  A through hole is formed in the lower part of the rear side of the gripping pieces 38, 38. After the movable side adapter fixing part 32 is attached to the movable part 114, the lock pin 36 is inserted into the through hole.

Next, attachment of the movable adapter fixing portion 32 to the movable portion 114 will be described.
The movable-side adapter fixing part 32 has a size of the protruding part 34 c and the coil springs 40, 40 so that the distance between the pair of gripping pieces 38, 38 is narrower than the width of the movable part 114 before being attached to the movable part 114. Is set.

  When attaching the movable adapter 30 to the movable part 114, first, an operator widens the pair of gripping pieces 38, 38 to the left and right so as to be larger than the width of the movable part 114. After positioning the movable part 114 between the pair of gripping pieces 38, the pair of gripping pieces 38, 38 are released. As a result, the pair of gripping pieces 38 and 38 are moved toward the movable portion 114 by the biasing force of the coil spring 40. Thus, the movable portion 114 is sandwiched between the pair of gripping pieces 38, 38, the upper L-shaped gripping piece 38 covers the upper portion of the movable portion 114, and the upper portion of the other gripping piece 38 is covered. . Then, the lock pin 36 is inserted into the through-holes of the pair of gripping pieces 38, 38 so that the tip end portion of the lock pin 36 protrudes toward the movable portion 114.

  Thereby, the movable adapter 30 is attached to the movable part 114. At this time, the movable side adapter jaw part 34 extends forward from the tip of the movable part 114, and the fixed side adapter head part 14 and the movable side adapter jaw part 34 face each other in the vertical direction. The distal end of the movable adapter jaw portion 34 is arranged substantially the same as the distal end of the movable portion 114. The distal end of the movable adapter jaw portion 34 may be disposed above the distal end of the movable portion 114. Further, since the distal end of the fixed adapter head portion 14 is disposed above the distal end of the fixed portion 112, the gap 50 between the distal end of the fixed adapter head portion 14 and the distal end of the movable adapter jaw portion 34 is the largest. Significantly, the maximum width of the gap 140 between the distal end of the fixed portion 112 and the distal end of the movable portion 114 can be made larger.

  Next, the usage method of the stray link tong 100 using this embodiment is demonstrated. When the object to be gripped is thicker than the electric wire and cannot be gripped by the stray link tongue 100, the indirect live tool adapter 1 of this embodiment is attached to the tip tool 110. Specifically, the worker fixes the fixed adapter 10 to the distal end portion 122 a of the fixed portion 112 and fixes the movable adapter 30 to the movable portion 114. Next, the worker adjusts the opening degree of the gap 50 to such an extent that an object to be grasped can be inserted. Then, the worker inserts the object into the gap 50, positions the object between the fixed adapter head portion 14 and the movable adapter jaw portion 34, and the worker rotates the insulating operation rod 150 counterclockwise. As a result, the movable adapter jaw portion 34 moves upward, and an object is gripped between the fixed adapter head portion 14 and the movable adapter jaw portion 34.

  In the present embodiment, the width of the fixed adapter head portion 14 and the movable adapter jaw portion 34 can be adjusted to a maximum of 13.0 cm and a minimum of 9.5 cm. For this reason, it becomes possible to hold | maintain a tension insulator, for example.

  According to the present embodiment configured as described above, the fixed adapter 10 is attached to the fixed part 112 of the tip tool 110, and the movable adapter 30 is attached to the movable part 114. An object can be gripped between the side adapter jaw portion 34. At this time, the maximum gap between the fixed adapter head portion 14 and the movable adapter jaw portion 34 can be made larger than the maximum gap between the fixed portion 112 and the movable portion 114 in the tip tool 110. An object that cannot be gripped by the tip tool 110 such as a tension insulator can be gripped by attaching the adapter 1 for an indirect live tool to the tip tool 110. As described above, it is possible to provide the adapter 1 for an indirect hot wire tool that can have a function of gripping a thick object that cannot be gripped by the tip tool 110.

  Further, according to the present embodiment, the fixed adapter 10 further includes hooks 18 that connect both ends of the fixed adapter main body 12, so that the fixed adapter main body 12 formed in a substantially U shape is It is possible to prevent the object from being opened when the object is gripped through the indirect hot wire tool adapter 1. Thereby, it is possible to reliably maintain the state where the stationary adapter 10 is attached to the stationary portion 112 of the tip tool 110.

  Moreover, according to this embodiment, the movable side adapter 30 is further provided with the lock pin 36 which protrudes to the movable part 114 side, and the state which attached the movable side adapter to the movable part of an indirect hot wire tool is maintained reliably. It becomes possible. That is, when a downward force is applied to the movable adapter jaw 34 when gripping an object via the indirect hot-wire tool adapter 1, the movable adapter jaw 34 rotates and a pair of gripping pieces 38. , 38 try to move upward. At that time, since the lock pin 36 contacts the movable portion 114, the rotation of the movable adapter jaw portion 34 is restricted. This makes it possible to prevent the movable adapter jaw portion 34 from moving when an object is gripped via the indirect hot tool adapter 1.
