The present invention relates to a lifting support member for lifting and supporting at a height of a structure such as the above.

  In general, in an indirect hot line work in which a high place such as a structure, for example, a delivery electric wire or the like installed between utility poles is worked in a live line state, an indirect hot wire tool such as a hot stick and a clipper is used. These indirect hot-wire tools are accommodated in, for example, a storage bag and are lifted up to the upper part of the utility pole. During the operation, the storage bag is in a state of being suspended on a scaffold bolt, for example. And an operator performs indirect hot wire construction, taking in and out the indirect hot wire tool from a storage bag. There is a case where the indirect hot line work is carried out by getting on a bucket of an aerial work vehicle, but in this case, the storage bag is suspended from the bucket.

  Here, FIGS. 14 and 15 are views showing a state in which the storage bag 12 is suspended from the scaffold bolt 13a of the utility pole 13 in a state where the indirect hot wire tool 11 is stored in the storage bag 12, The storage bag 12 is made of, for example, a material such as canvas, and includes a bag-shaped storage bag portion 12a in which the indirect hot-line tool 11 is stored. One side of the storage bag portion 12a (in the illustrated example, The upper surface side) is opened as an opening surface.

  A suspension belt 12b is attached to the storage bag portion 12a. The length (length in the longitudinal direction) of the storage bag portion 12a is approximately 1 meter, and the length of the indirect hot wire tool 11 is approximately 1.3 meters to 1.6 meters, depending on the type. It is.

  When performing indirect hot wire construction, a rope or the like is connected to the hanging belt 12b in advance, the indirect hot wire tool 11 is stored in the storage bag portion 12a, and the operator climbs the electric pole 13, and then the rope. To lift the storage bag 12. When the operator pulls up the storage bag 12 on the electric pole 13, the rope is removed from the suspension belt 12b, and then the suspension belt 12b is hooked on the scaffold bolt 13a and the storage bag 12 is suspended on the scaffold bolt 13a as shown in the figure. And an operator performs indirect hot wire construction, taking in and out the indirect hot wire tool 11 from the storage bag 12.

On the other hand, in order to carry out indirect hot wire construction while ensuring safety, hold the power distribution material of the electric wire with the indirect hot wire tool such as an insulation operation rod fixed to the arm of the utility pole, or connect the indirect hot wire tool to the electric wire. Indirect hot-wire work may be carried out by temporarily suspending the wire in an electric wire, and as an indirect hot wire tool used at this time, in order to lock an insulating operation rod having a construction work member at the tip to the electric wire The one provided with the hook may be used (for example, see Patent Document 1).

  Hereinafter, an example of a lifting support member for an indirect hot wire tool according to an embodiment of the present invention will be described with reference to the drawings. A lifting support member for an indirect hot wire tool (hereinafter simply referred to as a support member) according to the present embodiment is used to lift the indirect hot wire tool to a high place such as a utility pole during indirect hot wire construction. Indirect hot-wire tools include, for example, a biaxial rotating operation bar, a stray link tong, an insulating jacket, and a common operating bar (insulating operating bar) shown in FIGS. In the following description, a stray link tong will be described as an example of the indirect hot tool.

  FIG. 2 is a view showing a stray link tong, FIG. 2 (a) is a view showing the whole, and FIG. 2 (b) is a view showing a tip portion thereof. The stray link tong 21 has an insulating main body 21a, and a holding portion (gripping portion) 21b shown in FIG. The illustrated holding portion 21b has a hook-shaped claw portion 211 having one end attached to the main body portion 21a, and a moving body 212 that is opposed to the claw portion 211 and is movably attached to the main body portion 21a in the axial direction. And have. For example, a screw shaft body 213 is inserted (arranged) along the central axis in the main body portion 21a, and a moving body 212 is attached to the tip of the screw shaft body 213.

  Then, when the rear end portion of the main body portion 21a is rotated rightward, the screw shaft body 213 is retracted, and the interval (gap) between the claw portion 211 and the moving body 212 is increased (that is, the holding portion 21b is open). On the other hand, when the rear end portion of the main body portion 21a is rotated leftward, the screw shaft body 213 moves forward, and the interval between the claw portion 211 and the moving body 212 is narrowed (that is, the holding portion 21b is closed). In this way, during the indirect hot-wire construction, the holding portion 21b is opened and closed by rotating the main body portion 21a, and the holding portion 21b (that is, between the claw portion 211 and the moving body 212) has an electric wire. Hold with a pinch.

  As shown in FIG. 2B, the holding portion 21b is provided with a knob portion (lock mechanism) 214. When the knob portion 214 is operated, the screw shaft body 213 is prevented from moving, and the main body portion. The screw shaft body 213 does not advance or retract even if the 21a is rotated. That is, the holding part 21b is locked. When the knob portion 214 is operated again, the lock is released.

  By the way, when performing indirect hot wire construction, as described above, an indirect hot wire tool such as a stray link tong is housed in a storage bag portion of a storage bag (not shown), and an operator makes a utility pole (not shown). After that, the storage bag is pulled up by the rope. When the worker pulls up the storage bag on the utility pole, the worker hooks the suspension belt on the scaffolding bolt and suspends the storage bag on the scaffolding bolt. Thereafter, the operator performs indirect hot line work while taking in and out an indirect hot line tool such as a stray link tong from the storage bag.

  On the other hand, when the stray link tong 21 is pulled up to the utility pole as a single unit, a rope or the like is wound around the stray link tong 21 and the stray link tong 21 is pulled up to the utility pole. However, the winding of the rope is just troublesome. In addition, the work of unwinding the rope must be performed on the utility pole, which is not preferable from the viewpoint of safety. Therefore, in the present embodiment, the stray link tong 21 is suspended from the utility pole using the support member.

  First, referring to FIG. 3A, the illustrated support member 31 has a round bar-shaped support portion 32, and a pair of clamping portions 33 a and 33 b are attached to the surface of the support portion 32. ing. Each of these clamping parts 33a and 33b is shape | molded, for example with the elastic material. Here, paying attention to the sandwiching portion 33a, the sandwiching portion 33a has an attachment portion 34a and a pair of gripping bodies 34b and 34c formed integrally with the attachment portion 34a. The inner peripheral surfaces of the attachment portion 34a and the gripping bodies 34b and 34c are formed into arcuate surfaces, and the tip portions of the gripping bodies 34b and 34c are opposed to each other with a slight gap.

  As shown in FIG. 3A, the outer peripheral surface of the cylinder is defined by the inner peripheral surfaces of the mounting portion 34 a and the gripping bodies 34 b and 34 c, and the diameter of the cylinder is the same as that of the main body portion 21 a of the stray link tongue 21. Smaller than the diameter. In addition, the clamping part 33b is comprised similarly to the clamping part 33a.

  Referring to FIG. 3 (b), the holding portions 33a and 33b are fixed to the surface of the support portion 32 with a screw 35 at a predetermined interval (in the example shown, the attachment portion 34a is supported by the screw 35 with the support portion 32). 32). Subsequently, referring to FIGS. 3C and 3D, the diameters of the gripping bodies 34 b and 34 c are smaller than the outer diameter of the main body (rod-shaped part) 21 a of the stray link tongue 21, but the gripping bodies 34 b and 34 c Is molded from an elastic material (for example, resin). When the main body portion 21a is pushed into from the opening end side, the opening end side widens and the main body portion 21a is inserted into the gripping bodies 34b and 34c.

  After insertion of the main body 21a, the inner peripheral surfaces of the gripping bodies 34b and 34c abut on the outer peripheral surface of the main body 21a, and the diameters of the gripping bodies 34b and 34c are smaller than the outer diameter of the main body 21a. Thus, the main body 21a is gripped by the grippers 34b and 34c.

  As described above, after the support member 31 is mounted on the main body portion 21a, the support member 31 and the rope are connected to each other through a lifting device such as a rope between the support member 31 and the main body portion 21a. The tongs 21 may be lifted.

  When the stray link tong 21 is lifted, it is only necessary to insert a rope or the like between the support member 31 and the main body portion 21a, so that it is not necessary to bind the stray link tong 21 itself with a rope or the like as in the prior art. The stray link tongs 21 can be lifted up very easily.

  By the way, the stray link tong 21 has a holding portion 21b attached to the tip thereof, so that the tip side is slightly heavy. For this reason, as shown in FIGS. 3C and 3D, the support member 31 is preferably mounted in the vicinity of the distal end portion of the stray link tongue 21. And the clamping force by clamping part 33a and 33b is set more than the clamping force which can fully bear the dead weight when the stray link tong 21 is lifted.

  Subsequently, another example of the support member according to the embodiment of the present invention will be described with reference to FIGS. 4 and 5. A support member 41 shown in FIG. 4 is formed of an elastic material (for example, resin), and includes a cylindrical tubular body 42 and a hook portion 43 formed integrally with the tubular body 42. As shown in the drawing, a cut portion (slit) 44 is formed along the longitudinal direction of the cylindrical body 42, and the width of the cut portion 44 is larger than the outer diameter of the main body portion 21 a of the stray link tongue 21. small. Further, the inner diameter of the cylindrical body 42 is slightly larger than the outer diameter of the main body portion 21a.

  Since the support member 41 is formed of an elastic material, when the support member 41 is mounted on the main body portion 21a, the cut portion 44 may be expanded and the main body portion 21a may be inserted from the cut portion 44. . After the main body portion 21a is inserted from the cut portion 44 in this way, the cylindrical body 42 returns to its original shape, that is, the width of the cut portion 44 returns to its original state, and the cylindrical body 42 is returned to the main body portion. There is no way out of 21a.

  On the other hand, as shown in the drawing, the support member 41 is mounted on the main body 21a between the holding portion 21b and the flange 21c attached to the main body 21a. Therefore, although the inner diameter of the cylindrical body 42 is slightly larger than the outer diameter of the main body portion 21a, the movement of the support member 41 in the longitudinal direction of the main body portion 21a is blocked by the holding portion 21b and the flange portion 21c. The support member 41 will not fall out of the main body 21a.

  When the stray link tong 21 is lifted, after attaching the support member 41 to the main body 21a as described above, the tip of a rope (not shown) is hooked on the hook 43 (at this time, the tip of the rope Is preferably in the form of a ring). Then, the stray link tongs 21 are lifted up by a rope. And after lifting the stray link tong 21, the rope is removed from the hook portion 43, and the stray link tong 21 is used in the indirect hot wire construction.

  In addition, when using it by indirect hot wire construction, it is desirable to leave the support member 41 attached to the main body 21 a of the stray link tong 21. That is, when the storage bag (not shown) is already suspended from the scaffolding bolt of the utility pole (not shown), after the stray link tong 21 is used, the stray link tong 21 is temporarily stored in the storage bag. It will be.

  At this time, if the side surface of the storage bag portion of the storage bag is inserted between the hook portion 43 and the cylindrical body 42, the stray link tongue 21 is supported by the storage bag portion by the hook portion 43. Thus, the stray link tongue 21 does not wobble (since the cylindrical body 42 can move on the main body portion 21a between the holding portion 21b and the flange portion 21c, the stray link tongue 21 can be easily moved by the hook portion 43. Can be supported by the storage bag).

  If the above-mentioned support member 41 is used, the support member 41 can be easily attached to the main body portion 21a of the stray link tong 21, and a rope or the like is hooked on the hook portion 43 to easily lift the stray link tong 21 on the power pole. be able to.

  Further, when the stray link tong 21 is stored in the storage bag, the stray link tong 21 is held by the storage bag by the hook portion 43, so that the stray link tong 21 can be prevented from wobbling. As a result, the storage bag suspended from the scaffolding bolt does not become unstable, and the situation of the storage bag falling can be avoided.

  Next, referring to FIG. 5, in the illustrated support member 51, the same components as those of the support member 41 shown in FIG. In the support member 51, similarly to the support member 41, a cut portion 52 is formed along the longitudinal direction of the cylindrical body 42, and the fracture surface of the cut portion 52 is corrugated.

  Here, referring to FIG. 6, when the illustrated support member 51 is attached to the main body 21 a of the stray link tongue 21, the main body 21 a is inclined from the upper or lower opening surface of the cylindrical body 42. Insert into. Then, since the support member 51 is formed of an elastic material, the cylindrical body 42 is pushed and spread, and as shown in the drawing, both fractured surfaces of the cut portion 52 are portions where the outer peripheral surface of the main body portion 21a abuts. As shown in the figure, the contact portion with the main body portion 21a is distorted to the outside, and when viewed from the front, the peak portion becomes smaller and becomes a small peak.

  Then, after inserting the main body portion 21a into the cylindrical body 42, as shown in FIG. 7, when the main body portion 21a is brought upright, the distortion of the cylindrical body 42 is eliminated, and the notch portion 52 returns to the original state. However, both broken surfaces of the cut portion 52 are in a state in which large mountain portions are continuous.

  As shown in the figure, in the state where the main body portion 21a is inserted into the cylindrical body 42 and the main body portion 21a is upright, the cut portion 52 is bent (because it is wavy in a curved shape), so that the peak portion Alternately becomes a state (overlapping state) covering the outer peripheral surface of the main body portion 21a, so that the support member 51 can be reliably attached to the main body portion 21a, and the support member 51 may fall off from the main body portion 21a. Absent.

  Next, still another example of the support member according to the embodiment of the present invention will be described with reference to FIG. The support member 61 shown in the figure has a cylindrical shape, and a strip-shaped notch is formed along the outer periphery at the center thereof (the notch is, for example, approximately half the size of the outer peripheral surface). is there). A pair of arcuate flange body portions 62a and 62b are positioned above the notch and are opposed to each other with a predetermined gap.

  Similarly, a pair of arcuate flange body parts 63a and 63b are positioned below the notch part and face each other with a predetermined gap.

  The flange body portions 62a, 62b, 63a, and 63b constitute a part of the outer peripheral surface of the support member 61. The flange body portions 62a, 62b, 63a, and 63b have flange body portions 62a, Bending portions 62c, 62d, 63c, and 63d are formed by bending in the direction opposite to the extending direction of 62b, 63a, and 63b, respectively.

  As shown in the figure, the flange body portions 62a and 63a are connected to each other, and the end portions of the ring guide bodies 64a are respectively attached to the flange body portions 62a and 63a. Similarly, the flange body portions 62b and 63b are connected. Thus, the end portions of the ring guide body 64b are attached to the flange body portions 62b and 63b, respectively. A half ring body 65 is disposed in the support member 61 (the diameter of the half ring body 65 is slightly smaller than the inner diameter of the support member 61). As shown in the figure, the half ring body 65 is a ring guide body. It can be rotated along the peripheral surface of the support member 61 by 64a and 64b.

  Although not appearing in FIG. 8, the half ring body 65 has an outer circumferential length that is substantially half of the ring body, and bent portions (not shown) similar to the bent portions 62c, 62d, 63c, and 63d described above are provided at both ends thereof. ) Is formed. Therefore, when the half ring body 65 is rotated, the half ring body 65 can be rotated until the bent portion is caught by the ring guide body 64a or 64b. The half ring body 65 described above is positioned at the position of the above-described notch, and has a width slightly smaller than the width of the notch.

  When mounting the above-described support member 61 on the main body 21a of the stray link tongue 21, the half ring body 65 is rotated in the direction indicated by the solid line arrow or the broken line arrow in the figure to open the notch. When the main body portion 21a is pushed through the gap, the support member 61 is formed of an elastic material. Therefore, the flange body portions 62a, 62b, 63a, and 63b are bent, and the gap is expanded. 21 a can be inserted into the support member 61.

  After inserting the main body portion 21a into the support member 61, the half ring body 65 is rotated to close (close) the notch as shown in FIG. As a result, the wall surface is formed on a part of the support member 61 over the entire circumference, so that the support member 61 does not fall out of the main body portion 21a. In addition, the hook part is abbreviate | omitted in FIG.

  As described above, in the example shown in FIG. 8, when the support member 61 is attached to the main body 21 a, the peripheral surface is opened, the main body 21 a is inserted into the support member 61, and the main body 21 a is attached to the support member 61. Since the peripheral surface of the support member 61 is closed after the insertion, the support member 61 never falls out of the main body 21a after the support member 61 is attached to the main body 21a.

  Next, still another example of the lifting support member will be described with reference to FIGS. First, referring to FIGS. 9A and 9B, the illustrated support member 71 is made of, for example, canvas and is formed in a substantially rectangular shape in an open state. Hook fasteners (so-called magic tape (registered trademark)) 71a and 71b having hook surfaces and loop surfaces are formed on both end surfaces of the support member 71 in the longitudinal direction.

  As shown in FIG. 9A, the magic tape (registered trademark) 71 a is formed on the front surface side of the support member 71, and the magic tape (registered trademark) 71 b is formed on the back surface side of the support member 71. As shown in the figure, a rope locking portion (hook portion) 71 c is formed on one surface (front surface side) of the support member 71.

  When the above-described support member 71 is attached to the main body portion 21a of the stray link tongue 21, the support member 71 is wound around the main body portion 21a as indicated by the solid line arrow in the figure, and Velcro tapes 71a and 71b are wound around. The support members 71 are formed in a cylindrical shape (see FIG. 9B, and the hook portion 71c is omitted in FIG. 9B).

  In addition, when the support member 71 is bonded with Velcro (registered trademark) 71a and 71b to form a cylinder, the inner diameter of the cylinder is slightly smaller than the outer diameter of the main body 21a. As a result, when the support member 71 is wound around the main body portion 21a and the Velcro tapes 71a and 71b are bonded to each other, the main body portion 21a is held by the support member 71.

  In this manner, after the support member 71 is wound around the main body portion 21a, the stray link tongs 21 are suspended from the utility pole through the rope through the hook portion 71c. Note that the adhesive strength of the Velcro (registered trademark) 71 a and 71 b is set to allow for a safety factor at least for the weight of the stray link tongue 21.

  In the example shown in FIG. 9, there is an advantage that the support member 71 can be easily mounted on the stray link tongue 21 simply by winding the support member 71 around the stray link tongue 21 and bonding the Velcro (registered trademark) together. .

  Subsequently, referring to FIGS. 10A and 10B, the illustrated support member 72 includes an inner member 73 and an outer member 74. The outer member 74 has a cylindrical shape and is disposed outside the inner member 73 concentrically with the inner member 73. A part of the peripheral surface (side surface) of the external member 74 is cut off in the longitudinal direction to form an opening 74a. The inner member 73 has first and second inner member pieces 73a and 73b, and the first and second inner member pieces 73a and 73b are outer members 74 by first and second springs 73c and 73d, respectively. It is supported by the inner peripheral surface of.

  In the state where the first and second inner member pieces 73a and 73b are supported by the outer member 74 by the first and second springs 73c and 73d, as shown in FIG. A cylindrical part is formed by the material pieces 73a and 73b.

  As shown in the drawing, flange-shaped portions 73e and 73f are formed on one end portions of the first and second inner member pieces 73a and 73b, respectively, and the flange-shaped portions 73e and 73f are formed on the opening 74a described above. The insertion port 73g is formed by the flange-shaped portions 73e and 73f. A screw hole is formed in the peripheral surface of the outer member 74, and the screw portion 75 is inserted through the screw hole. The tip of the screw portion 75 is in contact with the outer peripheral surface of the first inner member piece 73a.

  When the support member 72 is mounted on the main body portion 21a of the stray link tongue 21, the main body portion 21a is pushed from the insertion port 73g as shown by the solid line arrow in FIG. Although the insertion port 73g is smaller than the outer diameter of the main body 21a, the first and second inner member pieces 73a and 73b are supported by the outer member 74 by the first and second springs 73c and 73d. If it is going to push in the main-body part 21a in the insertion port 73g, the insertion port 73g will spread and it can insert the main-body part 21a easily.

  When the main body portion 21a is inserted inside the cylindrical portion defined by the first and second inner member pieces 73a and 73b and then the screw portion 75 is rotated in the tightening direction, the screw portion 75 becomes the first inner member. It advances to the piece 73a side and presses the 1st inner member piece 73a. As a result, the diameter of the cylindrical portion defined by the first and second inner member pieces 73a and 73b is reduced, and the main body portion 21a is tightened by the first and second inner member pieces 73a and 73b. And the main-body part 21a is clamped by the 2nd inner member pieces 73a and 73b.

  As described above, after the support member 72 is attached to the main body portion 21a, the stray link tong 21 is suspended from the utility pole through a rope through a hook portion (not shown).

  As shown in FIG. 11B, on the opposite side of the leaf spring 77, an insertion port 76c is defined by the first and second member pieces 76a and 76b. Further, a screw hole is formed in the peripheral surface of the first member piece 76a, and the screw portion 78 is inserted through the screw hole.

  When the above-described support member 76 is attached to the main body portion 21a of the stray link tongue 21, the main body portion 21a is pushed from the insertion port 76c as shown by a solid arrow in FIG. Although the insertion port 76c is smaller than the outer diameter of the main body 21a, the first and second member pieces 76a and 76b are connected by a leaf spring 77, so that the main body 21a is pushed into the insertion port 76c. Then, the insertion port 76c can be expanded and the main body 21a can be easily inserted.

  After the main body portion 21a is inserted into the inside of the cylindrical portion defined by the first and second member pieces 76a and 76b, when the screw portion 78 is rotated in the tightening direction, the screw portion 78 moves forward, and the main body portion 21a. Press. As a result, the diameter of the cylindrical portion defined by the first and second member pieces 76a and 76b is reduced, and the main body portion 21a is tightened by the first and second member pieces 76a and 76b, whereby the first and second member pieces 76a and 76b are tightened. The main body 21a is sandwiched between the two member pieces 76a and 76b.

  As described above, after the support member 76 is mounted on the main body portion 21a, the leaf spring 77 is used as a locking portion (that is, a hook portion), the rope is passed through the leaf spring 77, and the stray link tongue 21 is suspended from the utility pole. increase. In the example shown in FIG. 11, since the main body portion 21a is securely gripped by the first and second member pieces 76a and 76b by operating the screw portion 78, there is no possibility that the stray link tongue 21 falls off. .

  Next, referring to FIG. 12, the illustrated support member 79 is formed of an elastic material such as resin and has a substantially truncated cone shape. The outer peripheral surface (outer peripheral wall) 79a has a ridge line (longitudinal direction). A cutout portion is formed along. The support member 79 has an inner peripheral surface (inner wall) 79b. The inner wall 79b is formed in a semi-cylindrical shape, and the opening portion thereof coincides with the above-described notch portion to define the insertion port 79c. .

  A main body portion 21a of the stray link tongue 21 described later is housed in a space (groove portion) defined by the inner wall 79b. Further, a locking portion (loop-shaped locking portion) 79d is formed on the outer peripheral wall 79a.

  In the illustrated support member 79, except for the space defined by the inner wall 79 b, the bottom surface of the support member 79 is closed (that is, has a bottom), and the operation shaft piece 80 penetrates through the bottom surface. The operation shaft piece 80 is inserted into a space defined by the outer peripheral wall 79a and the inner wall 79b, and is rotatably supported on the bottom surface (specifically, a long hole 80b is formed on the bottom surface, However, racks are disposed on both sides of the long hole 80b, and pinions (not shown) attached to the operation shaft piece 80 are screwed into these racks (the pinion is Sandwiched by rack))). A bevel gear 80 a is formed at the tip of the operation shaft piece 80.

  On the other hand, a screw hole is also formed in the inner wall 79b, and a screw shaft body 81 is screwed into the screw hole, and a bevel gear 81a is formed on the head of the screw shaft body 81. And the front-end | tip of the screw shaft body 81 has faced the space (groove part) prescribed | regulated by the inner wall 79b. The aforementioned bevel gear 80a meshes with the bevel gear 81a.

  When the above-described support member 79 is attached to the main body portion 21a of the stray link tongue 21, the main body portion 21a is pushed from the insertion port 79c as shown by a solid line arrow in FIG. Although the insertion port 79c is smaller than the outer diameter of the main body 21a, the support member 79 is formed of an elastic material. Therefore, when the main body 21a is pushed into the insertion port 76c, the insertion port 76c is widened easily. The main body 21a can be inserted into the main body 21a.

  When the operation shaft piece 80 is rotated after the main body portion 21a is inserted into the space defined by the inner wall 79b, the rotation is transmitted to the screw shaft body 81 via the bevel gears 80a and 81a, and the screw shaft body 81 advances. Then, the main body 21a is pressed. As a result, the space defined by the inner wall 79b is narrowed, the main body 21a is tightened by the inner wall 79b, and the main body 21a is sandwiched by the inner wall 79b.

  As described above, after the support member 79 is attached to the main body 21a, the stray link tong 21 is suspended from the utility pole by passing the rope through the loop-shaped locking portion 79d. In the example shown in FIG. 12, since the main body portion 21a is securely gripped by the inner wall 79b by operating the operation shaft piece 80, the stray link tongue 21 does not fall off. Further, since the operation shaft piece 80 is disposed so as to protrude from the bottom surface side of the support member 79, the operation shaft piece 80 does not get in the way when the stray link tongue 21 is lifted.

  Further, since the locking portion is in a loop shape, the rope can be passed very easily. After the suspension portion is lifted on the utility pole, the stray link tongs 21 can be attached to the scaffold bolt (not shown) by the loop-shaped locking portion. Can also be hung.

  Referring to FIG. 13, the illustrated support member 82 is formed into a hollow substantially disk shape with an elastic material such as resin.

And the main-body part 21a (not shown in FIG. 13) of the stray link tongue 21 is accommodated in the space prescribed | regulated by this groove part 82a. A loop-shaped locking portion 82 b is formed on the lower surface (bottom surface) side of the support member 82.

  In the illustrated support member 82, the operation shaft piece 83 is inserted into the support member 82 through the bottom surface, and the operation shaft piece 83 is rotatably supported on the bottom surface (specifically, on the bottom surface). A long hole 83b is formed, and racks are arranged on both sides of the long hole 83b (not shown), and pinions (not shown) attached to the operation shaft piece 83 are attached to these racks. ) Are screwed together (the pinion is clamped by the rack)). A bevel gear 83 a is formed at the tip of the operation shaft piece 83.

  On the other hand, a screw hole is also formed in the wall surface of the groove 82 a described above, and a screw shaft body 84 is screwed into the screw hole, and a bevel gear 84 a is formed at the head of the screw shaft body 84. The tip of the screw shaft body 84 faces the space defined by the groove 82a. The aforementioned bevel gear 83a is meshed with the bevel gear 84a.

  When the above-described support member 82 is attached to the main body portion 21a of the stray link tongue 21, the main body portion 21a is inserted into the groove portion 82a from the side surface side of the support member 82 as shown by a solid line arrow in FIG. Since the diameter of the groove 82a is substantially equal to the outer diameter of the main body 21a and the support member 82 is formed of an elastic material, insertion of the main body 21a is not hindered.

  When the operation shaft piece 83 is rotated after the main body portion 21a is inserted into the space defined by the groove portion 82a, the rotation is transmitted to the screw shaft body 84 via the bevel gears 83a and 84a, and the screw shaft body 84 advances. Then, the main body 21a is pressed. As a result, the space defined by the groove 82a is slightly narrowed, and the main body 21a is held in the space defined by the groove 82a by the tip of the screw shaft body 84 and the groove 82a.

  As described above, after attaching the support member 82 to the main body portion 21a, the stray link tong 21 is suspended from the power pole through the rope through the loop-shaped locking portion 82b. In the example shown in FIG. 13, by operating the operating shaft piece 80, the main body portion 21a is held in the space defined by the groove portion 82a, and there is no possibility that the stray link tong 21 falls off.

  Further, since the operation shaft piece 83 is disposed so as to protrude from the bottom surface side of the support member 82, the operation shaft piece 83 does not get in the way when the stray link tongue 21 is lifted. Further, since the locking portion 82b has a loop shape, the rope can be passed very easily. After the suspension portion 82b is suspended from the utility pole, the stray link tongs 21 can be individually attached to the scaffolding bolt 21 by the loop-shaped locking portion (see FIG. (Not shown).
