  The protection target according to the present embodiment is a utility pole P having a predetermined length in the vertical direction L. Moreover, the protector 1 which concerns on this embodiment is used by the indirect hot wire operation | work performed close to this utility pole P, and in order to insulate and protect the utility pole P, it operates with the tool for indirect hot wire work, such as an insulated yacht. Possible insulation armor.

  The covering portion 2 covers a predetermined protection range of the utility pole P along the vertical direction L thereof. The protection range according to the present embodiment is a range that includes at least a half-circumferential portion that is an upper portion of a utility pole P that performs work on an aerial work vehicle or the like and that faces a live line that performs indirect hot line work. That is, the protection range according to the present embodiment does not cover the entire circumference of the utility pole P.

  The covering portion 2 is a rectangular sheet material, and in order to cover the protection range of the utility pole P, the vertical direction L1 has a length equal to or greater than the vertical length L of the protection range, and the width direction W1 (particularly 3) has a length equal to or greater than the length of the protection range in the circumferential direction R. The covering portion 2 is fixed at its upper end 21 portion, which is one end portion in the vertical direction L, to the fixing means 3 formed in an arc shape along the circumferential direction R of the utility pole P. The covering portion 2 is held in an arc shape along the circumferential direction R of the utility pole P by fixing the upper end 21 portion along the other end 51b portion from the one end 51a portion of the fixing means 3. The covering portion 2 covers the protection range of the utility pole P by being held in the shape of the fixing means 3.

  The covering portion 2 is held by being rounded into an arc shape by bringing the edge portions 23 and 24 on both sides in the width direction W1 closer to each other. That is, the covering portion 2 becomes rectangular when the one edge portion 23 and the other edge portion 24 are separated from each other and a gap formed between the one edge portion 23 and the other edge portion 24 is widened. However, when one edge 23 and the other edge 24 are brought close to each other and rounded, a cylindrical shape having a single cut is formed. Although the coating | coated part 2 which concerns on this embodiment is rounded and formed to such an extent that one edge part 23 and the other edge part 24 do not contact or overlap, the coating | coated part which concerns on this invention is limited to this. In addition, a cylindrical shape formed by winding one edge portion and the other edge portion so as to contact or overlap each other (the cross-sectional shape is circular, elliptical, rectangular, or other shape) is also included.

  The covering portion 2 is made of an insulating material, for example, E.C. V. It is made of A (ethylene-vinyl acetate copolymer) resin. The covering portion 2 is held in an arc shape by fixing the upper end 41 to the fixing means 3, but the covering portion 2 itself is a flexible sheet. On the utility pole P, utility pole accessories such as a free band, various electric conduits, and terminals are arranged so as to project radially from the outer periphery of the substantially cylindrical utility pole P and are mounted on the utility pole P. The covering portion 2 deforms its shape corresponding to the utility pole appendage protruding from the utility pole P. Therefore, the coating | coated part 2 can coat | cover the utility pole P, even if these utility pole accessories are attached to a utility pole.

  The fixing means 3 is formed in an arc shape along the circumferential direction R of the utility pole P, and fixes the covering portion 2 along the circumferential direction R of the utility pole P. The fixing means 3 includes a first fixing member 5 that fixes the upper end 21 side of the covering portion 2 to the utility pole P, and a second fixing member 6 that fixes the covering portion 2 on the lower end 22 side of the first fixing member 5. And comprising.

  The first fixing member 5 includes a clamping member 51 that clamps the covering portion 2 along the circumferential direction R of the utility pole P, and a binding member 52 that binds the both ends of the clamping member 51 so as to draw each other.

  The sandwiching member 51 includes an arc-shaped sandwiching portion 53 having an inner peripheral diameter substantially the same as the outer peripheral diameter of the utility pole P, guide portions 54 and 54 formed by turning both ends of the sandwiching portion 53 outward, The protection part 55 which protects the clamping part 53 and the guide parts 54 and 54 from the sliding contact with the utility pole P, and the holding part 56 which can hold | maintain the tool for indirect hot wire work are provided.

  The sandwiching portion 53 is elastically deformed in a direction in which both end portions thereof are separated so as to sandwich the peripheral side surface of the utility pole P and suspend the covering portion 2 from the utility pole P. The clamping portion 53 is formed of a reinforced plastic or an insulating steel material and has an insulating property.

  The guide portions 54 and 54 form a gap 54a (see FIGS. 2 and 3A) between them. As shown in FIGS. 4 (a) to 4 (c), by pressing the circumferential side surface of the utility pole P against the gap 54a and further pressing the guide portion 54, 54, the one end and the other end of the sandwiching portion 53 are placed outside. The gap 54a is widened (see FIG. 4B) while widening (in the direction in which they are separated from each other). The utility pole P is inserted inside the clamping part 53 through the gap 54a. And if the utility pole P is completely inserted inside the clamping part 53, the clamping part 53 will clamp the utility pole P along the circumferential direction R by the inner peripheral surface side (refer FIG.4 (c)).

  The protection part 55 is affixed to the inner peripheral surface of the clamping part 53 and the guide parts 54 and 54 (refer Fig.3 (a)). The protection part 55 is made of wear-resistant polyethylene and is configured to withstand wear due to friction with the utility pole P.

  The gripping part 56 is fixed to the outer peripheral surface of the clamping part 53. Specifically, the grip portion 56 is fixed at a substantially intermediate position in the circumferential direction of the sandwiching portion 53. Therefore, the gripping part 56 is arranged so that a force is evenly applied to both sides of the guide parts 54, 54 by being pressed toward the utility pole P from directly in front of the protection range of the utility pole P.

  As shown in FIG. 2, the constraining member 52 includes a long constraining rope 57 having insulating properties, and annular engaging portions 58 and 58 that can engage with the guide portions 54 and 54. The constraining rope 57 has a sufficient length to wind the space between one guide part 54 and the other guide part 54 in a shape of 8 and to restrain the guide parts 54, 54 to each other. The engaging portions 58 and 58 are fixed to both ends of the binding rope 57. The engaging portion 58 is fitted to the guide portion 54 and provided to fix one end of the binding rope 57 to the guide portion 54.

  The second fixing member 6 is elastically deformed so that the holding means 4 allows the one edge portion 23 and the other edge portion 24 of the covering portion 2 to be separated and held (see FIG. 5). Further, the second fixing member 6 moves the covering portion 2 in the circumferential direction R of the utility pole P as the holding means 4 releases the holding of the one edge portion 23 and the other edge portion 24 of the covering portion 2. It returns to the arc shape along (see FIGS. 1 and 2).

  The second fixing member 6 is a plate-like member that is formed by rounding in an arc shape along the circumferential direction R of the utility pole P. The second fixing member 6 is formed in an inverted V shape when the one end 61 and the other end 62 are spaced apart and spread in a planar shape. The second fixing member 6 is continuously wound and fixed from the one edge 23 to the other edge 24 on the lower end 22 side of the covering portion 2 rounded in an arc shape. The second fixing member 6 is arranged along the longitudinal direction in a direction in which the covering portion 2 is lifted from the edge portions 23 and 24 on the lower end 22 side of the covering portion 4. The second fixing member 6 has flexibility or flexibility such that the one end 61 side and the other end 62 side in the direction along the circumferential direction R of the utility pole P can be separated and deformed.

  The second fixing member 6 is formed of an elastic material having an elastic force that is weaker than an elastic force necessary for separating the one end 51a and the other end 51b of the holding portion 53 from each other. That is, when the one edge portion 43 and the other edge portion 44 of the covering portion 2 are separated due to the separation between the one end 51a and the other end 51b of the sandwiching portion 53, the second fixing member 6 is also separated from the one end portion and the other. The end portion is separated. However, even if the one end 61 and the other end 62 of the second fixing member 6 are separated from each other, the one edge portion 23 and the other edge portion 24 of the covering portion 2 are separated from each other. It is not separated from the other end 51b.

  As shown in FIGS. 1, 2, and 5, when the first fixing member 5 is fixed to the utility pole P, the holding means 4 contacts at least a part of the lower end 22 side of the covering portion 2 with the utility pole P. The edge portions 23 and 24 along the vertical direction L1 of the covering portion 2 can be held in the shape of the covering portion 2 that is separated from the utility pole P.

  The holding means 4 is arranged so that one edge 23 and the other edge 24 of the covering portion 2 are held away from the utility pole P, and the lower end 22 side of the one edge 23 and the other edge 24 is provided. In order to hold the first connecting portion 7 to be connected, the one edge portion 23 of the covering portion 2 and the other edge portion 24 along the utility pole P, the one edge portion 23 and the other edge portion 24 are connected. And a second connecting portion 8 to be provided.

  The first connecting portion 7 elastically deforms the second fixing member 6 with one edge portion 23 and the other edge portion 24 of the covering portion 2 formed in an arc shape along the circumferential direction R of the utility pole P. Thus, the one edge 23 and the other edge 24 are detachably connected in a state where the edges 23 and 24 are separated from the utility pole P. The 1st connection part 7 is provided in the lower end 22 side of the one edge part 23 and the other edge part 24, respectively. The first connecting portion 7 is in a state where one edge 23 and the other edge 24 of the covering portion 2 formed in an arc shape along the periphery of the utility pole P are separated from each other while being elastically deformed. The edge 23 and the other edge 24 are detachably coupled. The 1st connection part 7 is arrange | positioned at the surface F side of the one edge part 23 and the other edge part 24, respectively. The 1st connection parts 7 and 7 which concern on this embodiment are rectangular plate-shaped permanent magnets. This magnet has a magnetic force that couples more strongly than the force that separates one edge 23 and the other edge 24 of the covering portion 2 due to the elastic force of the second fixing member 6.

  The second connecting portion 8 removably connects the one edge portion 23 and the other edge portion 24 in a state where the covering portion 2 is formed in an arc shape along the circumferential direction R of the utility pole P. The 2nd connection part 8 which concerns on this embodiment is a hook_and_loop | surface fastener, has a hooking surface (hook) in one edge part 23, and has a to-be-latched surface (loop) in the other edge part 24. FIG. ing.

  Next, a method for mounting the protector 1 on the utility pole P according to the embodiment will be described with reference to FIGS. 4 and 5.

  The covering portion 2 is rolled up so that the lower end portion 22 of the edge portions 23 and 24 is not caught when the first fixing member 5 is fixed to the electric pole P and the first posture covering the protection range of the electric pole P. The posture can be changed to two postures. The covering portion 2 has a first posture suspended in an arc shape by first fixing the upper end 21 of the covering portion 2 to the first fixing member 5 of the fixing means 3. As shown in FIG. 5, the operator separates one edge 23 and the other edge 24 of the covering portion 2 from the covering portion 2 in the first posture, and places one end on the lower end 22 side. The edge portion 23 and the other edge portion 24 are rolled up so that the covering portion 2 is in the second posture. At this time, the second fixing member 6 is elastically deformed in a direction away from the one end 61 and the other end 62 while being repelled by an elastic force. The first fixing member 5 is not elastically deformed.

  The operator keeps the one edge portion 23 and the other edge portion 24 as they are, and in the state where the front and back of the lower end side of the covering portion 2 are reversed, the first connecting portion 71 and the other first edge portion are reversed. The connection part 72 is connected. An operator can maintain the covering portion 2 in the second posture without holding it with an indirect hot wire working instrument or the like.

  Next, the worker grips the grip portion 56 of the clamping member 51 with the indirect hot-wire work tool to bring it close to the protection range of the utility pole P that is the protection target (see FIG. 4A). The operator presses the utility pole P against the gap 54a between the guide portions 54, 54, and presses the utility pole P as it is. In the protector 1, the guide portions 54, 54 are separated from each other, one end and the other end of the holding portion 53 are separated, and a gap 54 a between the one end and the other end is opened. (See FIG. 4B). At this time, the covering portion 2 has one edge portion 23 and the other edge portion 24 on the upper end side of the covering portion 2 fixed to the sandwiching member 51 due to the separation between the one end 51 a portion and the other end 52 b portion of the sandwiching member 51. Are separated from each other, and the shape is maintained in a U-shape in a top view.

  When the operator completely holds the utility pole P inside the clamping portion 53, the protector 1 is temporarily attached to the utility pole P (see FIG. 4C). Therefore, the worker removes the indirect hot-wire working tool from the grip portion 56, separates the first connecting portion 71 from the other first connecting portion 72, and releases the connection. In addition, according to this procedure, the worker can perform this work by one person, while using the other indirect live-line work instrument while holding the indirect live-line work instrument in the gripping part 56, The first connecting portions 71 and 72 may be removed.

  When the connection by the first connecting portion 7 is released, the second fixing member 6 bent in an elastically deformed state is restored to the original arc shape by the elastic restoring force. When the second fixing member 6 is restored to the arc shape, the spread covering portion 2 is also restored to the original arc shape and covers the outer peripheral surface of the utility pole P.

  An operator goes to the opposite side of the utility pole P and connects one edge 23 and the other edge 24 of the covering portion 2 with the second connecting portions 8. In addition, the operator hooks the engaging portion 58 of the binding member 52 on one guide portion 54 and winds a binding rope 57 between the one guide portion 54 and the other guide portion 54, so that the guide portions 54, 54 is bound.

  In this way, after the operator holds the covering portion 2 and the utility pole P separated by the holding means 4, the fixing means 3 is fixed to the utility pole P, so that at least the lower end 22 side of the covering portion 2 is at least. Some do not contact the utility pole P. Therefore, since at least a part of the lower end 22 side of the covering portion 2 is not caught inside, the operator can easily fix the protector 1 to the utility pole P. Further, by releasing the holding of the covering portion 2 that is held away from the electric pole P, the electric pole P can be covered with the covering portion 2, so that the operator can easily protect the protective device 1 on the object to be protected. Can be installed.

  When the holding means 4 releases the holding of the one edge portion 23 and the other edge portion 24 of the covering portion 2, the covering portion 2 is moved in the circumferential direction R of the utility pole P by the elastic restoring force of the second fixing member 6. The original arc shape is restored along and is fixed to the utility pole P. Therefore, the worker can easily fix the covering portion 2 to the utility pole P on the lower end 22 side.

  The first connecting portion 7 can be held in a state where the one edge portion 23 and the other edge portion 24 of the covering portion 2 are separated from each other, and the first fixing member 5 is fixed to the utility pole P. Even at times, the lower end 22 side of one edge 23 and the other edge 24 of the covering portion 2 can be held away from the utility pole P.

  After the covering portion 2 is fixed to the utility pole P by the fixing means 3, the second connecting portion 8 connects one edge portion 23 and the other edge portion 24 of the covering portion 2, The edge portion 23 and the other edge portion 24 can be fixed so as not to be easily peeled off from the utility pole P.

  In addition, although the process which binds the guide parts 54 and 54 with the binding member 52 demonstrated the example performed after removing the holding | maintenance part 5 and coat | covering the coating | coated part 2 in the protection range of the utility pole P, it is limited to this. It is not a thing. That is, the step of binding the guide portions 54, 54 with the binding member 52 may be performed before or after any step, as long as the holding portion 53 is sandwiched between the utility poles P. It may be done at the same time.

  Next, a protector according to a second embodiment of the present invention will be described with reference to FIGS. The protector according to the second embodiment has the same configuration as the protector 1 according to the first embodiment. The configuration of the second embodiment that is the same as the protector 1 according to the first embodiment is given the same reference numeral, and the description thereof is omitted.

  Similarly to the first embodiment, the protector 101 according to the embodiment includes a covering means 2, a fixing means 103, and a second connecting portion (holding means) 8. In addition, since the 1st fixing member 5 and the 2nd connection part 8 are the same as the structure which concerns on 1st Embodiment among the coating | coated means 2 and the fixing means 103, below, the 2nd of the fixing means 103 is demonstrated. Only the fixing member 106 will be described.

  The second fixing member 106 is attached to the back surface R side of the covering portion 2 and holds the shape of the covering portion 2. The second fixing member 106 is provided with a fixing base 161 formed in an arc shape along the width direction W1 of the covering portion 2 and extending from both ends of the fixing base 161, and can be wound around the utility pole P. Appendices 162 and 162 are provided.

  The fixed base 161 is a semicircular plate material and has an inner peripheral diameter that is substantially the same as the outer peripheral diameter of the utility pole P. The fixed base portion 161 is disposed at a substantially intermediate position in the width direction W1 of the covering portion 2 and holds the shape of the covering portion 2 so that the covering portion 2 is along the outer peripheral half surface of the utility pole P.

  As shown in FIG. 8D, the winding parts 162 and 162 are long springs (spiral springs) in which the width direction W2 is curved in an arc shape. This spring is formed from an insulating material (for example, hard plastic), or is formed from an insulating coated metal plate.

  The winding parts 162 and 162 according to the present embodiment have wraps wound in the longitudinal direction L2 such that the convex surface 163 side curved in an arc shape is on the inner side. In addition, although the winding part 162,162 which concerns on this embodiment demonstrates the example which makes a convex surface 163 side become an inner side, you may make it the concave surface 164 side of the back side of the convex surface 163 become an inner side.

  The winding portions 162 and 162 can be changed between a first posture held in a straight line (see FIG. 8A) and a second posture wound in a spiral (see FIG. 8B). It is configured. In a state where the winding portions 162 and 162 are flattened in the longitudinal direction L, the elastic force is restricted, and the posture is held linearly (first posture). On the other hand, by bending the convex surface 163 side to the inside (in the direction of arrow F in FIG. 8D), the winding portions 162 and 162 are released from the restriction of the elastic force of the spiral spring (the elasticity of the spiral spring). When the force is applied), the posture is wound in the longitudinal direction L and deformed into a spiral shape (second posture).

  The winding portions 162 and 162 are attached to the covering portion 2 so that the surface wound in a spiral shape faces the inside of the covering portion 2 so as to be bent toward the back surface R side of the covering portion 2 in the second posture. . That is, the winding parts 162 and 162 according to the present embodiment are attached to the back surface R side of the covering part 2 over the entire length in the longitudinal direction L2 with the convex surface 163 side facing inward. The winding parts 162 and 162 hold the shape of the covering part 2 in a deformable manner. That is, when the winding portions 162 and 162 are in the first posture, the covering portion 2 is in a state where one edge portion 23 and the other edge portion 24 are widened in a U shape in a sectional view (FIG. 8 ( a)), in the second posture, one edge 23 and the other edge 24 are closed in a circular cross-sectional view (see FIG. 8C).

  Note that the second fixing member 106 according to the second embodiment is configured such that when the first fixing member 5 is fixed to the utility pole P, at least a part on the lower end 22 side of the covering portion 2 does not contact the utility pole P. Moreover, since the edge parts 23 and 24 along the up-down direction L of the coating | coated part 2 can be hold | maintained in the shape of the coating | coated part 2 spaced apart from the utility pole P, the lower end side of one edge part 23 and the other edge part 24 It also has a function as a holding means that eliminates the need for connection.
