Description

  The present invention relates to a low-pressure rack that supports a low-pressure insulator and an adapter for a low-pressure rack used therefor.

  Conventionally, a low-voltage rack that supports a low-voltage insulator is connected to a utility pole or a metal fitting that is connected to the utility pole, and the low-voltage line is secured to the low-voltage insulator to construct a low-voltage line to a general household.

  When the low-voltage line is fastened to the low-pressure insulator, as an example, a low-voltage rack (low-pressure insulator support metal fitting in Patent Document 1) as shown in FIG. A low-voltage wire is bound to a low-pressure insulator supported by a low-pressure rack using a bind wire as described in Document 2. The low-pressure insulator has a penetrating shaft (bolt rod 7 in Patent Document 1) that passes through the axis in the vertical direction, and a concave outer peripheral surface formed around the axis of the through-shaft on the outer periphery of the low-pressure insulator (Patent Document 1). Then, the groove 10 ′) is supported by the low-pressure rack in a state in which the groove 10 ′ is oriented in the horizontal direction (see FIG. 1 of Patent Document 1). Then, the low-voltage line stretched substantially horizontally is caught and fixed to the low-pressure insulator by the bind line in a state where the low-pressure line is horizontally fitted to the concave outer peripheral surface (see paragraph number 0010 of Patent Document 1).

As another example, an electric wire rack having a hook for hooking a low-voltage wire and a support hole for attaching the low-voltage wire as shown in FIG. Thus, the low-voltage wire is also retained using this electric wire insulator.

  When constructing a low-voltage line across a plurality of utility poles standing on a straight street using a low-voltage rack as described in Patent Document 1, the bind line for securing and fixing the low-voltage line to the low-voltage insulator is always substantially horizontal. You will receive the weight of the low-voltage line installed in the building. When the street is a curved road, the bind line receives not only the weight of the low-voltage line but also the tension of the low-voltage line acting in the lateral direction as the low-voltage line is stretched along the street. Further, since the low-voltage line swings by receiving wind force, the bind line also receives the swinging force of the low-pressure line.

  As described above, when the low-voltage line is installed using the low-pressure rack as described in Patent Document 1, the bind line that holds and fixes the low-voltage line to the low-pressure insulator receives the weight, tension, and swinging force of the low-voltage line. It is placed in a situation where it becomes easy to loosen. If the binding wire is loosened, the low-voltage wire is likely to drop off from the low-pressure insulator, and the covering member that covers the low-voltage wire comes into contact with the low-voltage rack, and there is a risk that the current flowing through the low-voltage wire leaks to the low-voltage rack. .

  Moreover, the insulator for electric wires described in Patent Document 3 has a special shape including a hook and a support hole, and is suitable for supporting a low-voltage line laid in a predetermined direction. It is not suitable for constructing a low-voltage line on a utility pole standing on a street with a shape, and is not versatile.

  An object of the present invention is to place a bind line for securing and fixing a low-voltage line to a low-voltage insulator on a low-voltage line erected on a utility pole standing on a street having various shapes in a state where it is difficult to loosen.

  The low-pressure rack of the present invention includes a first contact region that can contact the power pole along the length direction of the power pole, and the first low-pressure insulator axis that supports the low-voltage wire on the concave outer peripheral surface. A first arm that supports one end side of the shaft center perpendicularly to the contact area; a second arm that is positioned parallel to the first arm and supports the other end side of the shaft center; A second contact region is provided that connects one arm and the second arm, is in a non-perpendicular state with respect to the first contact region, and can contact the power pole along a length direction of the power pole. A connection member.

  Further, the low-pressure rack of the present invention as viewed from another surface is (A) a first arm that supports one end side of the low-frequency insulator supporting the low-voltage line on the concave outer peripheral surface with the low-speed insulator axially oriented vertically. A second arm positioned parallel to the first arm and supporting the other end of the shaft, and arranged in parallel to the axial direction of the low-pressure insulator, the first arm and the second arm A low-pressure rack main body portion provided with a connecting member, (B) a first side member provided with a first contact region that can contact the power pole along the length direction of the power pole, and one end side A second side member connected to a lower end side of the first side member and extending perpendicularly from the first side member to the first contact region to connect and fix the connection member of the low-pressure rack body, and the first The upper end side of the side member and the other end side of the second side member are connected to the first contact region. A third side member comprising a second abutment region which can be abutted to the utility pole along a length direction of the electric pole extends at an acute angle direction Te comprises a.

  The present invention also defines the low-pressure rack adapter.

  According to the present invention, on a straight street, the first abutment region provided on the first arm (first side member) is arranged along the length of the utility pole, and the low-pressure rack is attached to the utility pole so that The outer peripheral surface of the cable is opened upward, and the low-voltage line is placed on the low-pressure insulator to reduce the force received by the bind line by applying the own weight of the low-pressure line to the low-pressure insulator. By attaching the low-pressure rack to the utility pole along the second contact area of the third side member) along the length of the utility pole, the outer peripheral surface on the concave surface of the low-pressure insulator opens obliquely upward, and the low-voltage line is placed on the concave surface. It is possible to reduce the force that the bind line receives by applying both the dead weight of the low-pressure line that works in the vertical direction and the tension of the low-pressure line that works in the lateral direction to the low-pressure insulator by fitting to the outer peripheral surface. Standing For low-pressure line to be laid in utility pole to be, it can be placed a low pressure line arrested under difficult loosening the binding wire situation which is fixed to the low pressure insulators.

  An embodiment of the present invention will be described with reference to FIGS.

  FIG. 1A is a schematic diagram showing a low voltage line 202 stretched around a utility pole 201 standing on a straight street 200. FIG. 1B is a schematic diagram showing a low-voltage line 202 stretched around a utility pole 201 standing on a curved street 200a. The low-voltage rack 101 is fixed to the upper part of the electric pole 201 by a support band 203 around which the electric pole 201 is wound. The low-pressure rack 101 is substantially U-shaped when viewed from the side, and includes a first arm 102a and a second arm 102b that are parallel to each other, and a connecting member 102c that connects both of them. The outer side 102ab of the first arm 102a forms a first contact region that can contact the power pole 201 along the length direction of the power pole 201. The first arm 102 a and the second arm 102 b support both end portions of the bolt 103 as an axis that penetrates the low-pressure insulator 301. A part of the connecting member 102c is bent, and as shown in FIGS. 2 and 4, a flat portion 102cx and a slope portion 102cy are formed. The outer side 102 cb of the slope portion 102 cy of the connection member 102 c forms a second contact region that can contact the power pole along the length direction of the power pole 201.

  The outer peripheral surface of the low-pressure insulator 301 is formed in a concave shape along the axial direction of the bolt 103, and a support groove 303 that supports the low-voltage line 202 is formed. The low-voltage wire 202 is captured and fixed to the low-pressure insulator 301 by the bind wire 204 in a state in which the low-voltage wire 202 is fitted in the support groove 303 of the low-pressure insulator 301.

  As shown in FIG. 1A, the low-pressure rack 101 is formed into a power pole by a support band 203 in a state where the outer side 102ab of the first arm 102a as the first contact region is along the length direction of the power pole 201. It is possible to attach. By installing the low-pressure rack 101 in this way, the support groove 303 of the low-pressure insulator 301 opens upward, and the low-pressure wire 202 can be placed on the low-pressure insulator 301. Thus, the method of attaching the low-voltage rack 101 to the utility pole 201 is effective in the straight street 200 where the tension of the low-voltage line 202 applied in the direction approaching or separating from the utility pole 201 is small.

  Further, as shown in FIG. 1B, the low-pressure rack 101 has a low-pressure rack 101 in a state in which the outer side 102 cb of the slope portion 102 cy of the connection member 102 c as the second contact region is along the length direction of the utility pole 201. The rack 101 can be attached to a utility pole. By installing the low-pressure rack 101 in this way, the support groove 303 of the low-pressure insulator 301 opens obliquely upward inclined toward the utility pole 201, and the low-voltage line 202 is fitted to the support groove 303 and placed on the low-pressure insulator 301. It becomes possible to do. The method of attaching the low-voltage rack 101 to the utility pole 201 in this way is effective on the curved street 200a where the tension of the low-voltage line 202 applied in the direction approaching or separating from the utility pole 201 is relatively large.

  As described above, by adopting the mounting method of the low-pressure rack 101 shown in FIG. 1A and the mounting method of the low-pressure rack 101 shown in FIG. Both the tensions of the low-voltage line 202 acting in the direction can be applied to the low-pressure insulator, and the force received by the bind line 204 can be relatively reduced.

  Details of the structure of the low-pressure rack 101 in which the electric pole 201 can be attached as shown in FIGS. 1A and 1B will be described below.

  FIG. 2 is a left side view of the low-pressure rack 101 in a state where the low-pressure insulator 301 is fixed by the bolt 103. FIG. 3 is a rear view of the low-pressure rack 101. FIG. 4 is an external perspective view of the low-pressure rack 101. The low-pressure rack 101 is integrally formed in a substantially U shape in a side view, with the connection member 102c connecting the upper ends of the first arm 102a and the second arm 102b. Each of the first arm 102a, the second arm 102b, and the connection member 102c has a long flat plate shape. The first arm 102a and the second arm 102b are in a positional relationship separated from each other in parallel. As shown in FIG. 2, the connecting member 102c is bent inward by approximately 45 degrees to form a flat portion 102cx and a slope portion 102cy. The length of the slope portion 102cy is longer than the length of the flat portion 102cx. In the connecting member 102c, the flat portion 102cx and the first arm 102a form a right angle, and the inclined surface portion 102cy and the second arm 102b form an angle of approximately 135 degrees, so that the first arm 102a and the second arm 102b Connected.

  A low-pressure insulator 301 is disposed between the first arm 102a and the second arm 102b that are spaced apart from each other in parallel. The first arm 102a and the second arm 102b have a structure in which the bolt 103 serving as the axis of the low-pressure insulator 301 is penetrated and the low-pressure insulator 301 is supported by a fastening structure 110 provided at both ends of the bolt 103. . More specifically, bolt holes 102aa and 102ba into which the bolt 103 can be inserted are formed in the first arm 102a and the second arm 102b, respectively, at positions facing each other. The bolt 103 is inserted in a state where the opening portion of the through hole 302 formed in the low-pressure insulator 301 is aligned with each of the bolt hole 102aa formed in the first arm 102a and the bolt hole 102ba formed in the second arm 102b. When the bolt head 103a is in contact with the first arm 102a, the nut 103c is attached to the bolt rod 103b that passes through the second arm 102b and protrudes from the bolt hole 102ba, and the nut 103c is tightened. Both end portions are fixed to the first arm 102 a and the second arm 102 b, and the low-pressure insulator 301 is supported by the bolt 103. That is, the bolt head 103a and the nut 103c constitute a fastening structure 110. Also, the bolt 103 can be inserted in the direction opposite to the direction shown in FIGS. 2 and 3 as a matter of course. In this case, the bolt head 103a comes into contact with the second arm 102b, and the nut 103c is attached to the bolt rod 103b that passes through the first arm 102a and protrudes from the bolt hole 102aa.

  In each of the first arm 102 a, the second arm 102 b, and the connection member 102 c constituting the low-pressure rack 101, the side edges of both long sides are long sides of the low-pressure rack 101 toward the outside of the substantially U-shaped side view. The side wall 104 is formed toward the outside of the low-pressure rack 101. Therefore, each of the first arm 102a, the second arm 102b, and the connection member 102c has a U-shaped cross section in the width direction. The bending height of this bending process is higher than the protruding height of the bolt head 103a protruding outward from the bolt hole 102aa of the first arm 102a. Therefore, the outer side of the side wall 104 of the first arm 102a is The first arm 102a protrudes outward from the bolt head 103a protruding outward from the bolt hole 102aa. Here, when the bolt 103 and the nut 103c are inserted in a direction opposite to the direction shown in FIGS. 2 and 3, the tip of the bolt rod 103b protrudes from the bolt hole 102aa of the first arm 102a. . In this case, the first arm 102a is bent so that the outer side of the side wall 104 of the first arm 102a protrudes outside the protruding height of the bolt rod 103b protruding from the bolt hole 102aa. In addition, all the outer sides of the side wall 104 have a linear shape.

  The low-voltage rack 101 formed in this way can be fixed to the utility pole 201 by the support band 203 with the first arm 102a being along the length direction of the utility pole 201. That is, the outer side 102ab of the side wall 104, which is a bent portion of the first arm 102a, serves as a first contact area that can contact the utility pole 201. In addition, the low-voltage rack 101 can be fixed to the utility pole 201 by the support band 203 in a state where the slope portion 102 cy of the connection member 102 c is along the length direction of the utility pole 201. In other words, the outer side 102 cb of the side wall 104 formed on the connection member 102 c serves as a second contact area that can contact the utility pole 201.

  FIG. 5A is a right side view of the low-pressure rack 101 in a state where the outer side 102ab of the first arm 102a is fixed to the electric pole 201 along the electric pole 201. FIG. FIG. 5B is a right side view of the low-voltage rack 101 fixed to the utility pole 201 with the outer side 102 cb of the slope portion 102 cy along the utility pole 201. As described above, the outer side of the side wall 104 formed on each of the first arm 102a, the second arm 102b, and the connection member 102c has a linear shape. Therefore, the low-pressure rack 101 of the present embodiment is fixed to the utility pole by the support band 203 with the outer side 102ab of the first arm 102a along the length direction of the utility pole 201, as shown in FIG. can do. Further, as shown in FIG. 5B, the low-pressure rack 101 of the present embodiment is supported by the support band 203 in a state where the outer side 102 cb of the slope portion 102 cy of the connection member 102 c is along the length direction of the utility pole 201. It can be fixed to a power pole.

  When the low-pressure rack 101 is fixed to the utility pole 201 by the method shown in FIG. 5A, the support groove 303 of the low-pressure insulator 301 opens upward. When the low-pressure line 202 is fitted to the support groove 303 in this state and the low-pressure line 202 is placed on the low-pressure insulator 301, the low-pressure line 202 is subjected to its own weight on the low-pressure insulator 301, and the low-pressure line 202 is bound to the low-pressure insulator 301 correspondingly. The force applied to the binding line 204 to be fixed is reduced. As a result, the bind line 204 is not easily loosened. Further, even if the bind wire 204 is slack, the low-pressure wire 202 is kept in the state of being fitted to the support groove 303 by its own weight, and the low-voltage wire 202 is less likely to fall off from the low-pressure insulator 301 and the low-voltage wire 202 is covered. It is possible to prevent the member from coming into contact with the low-pressure rack 101 and damaging the covering member.

  When the low-voltage rack 101 is fixed to the utility pole 201 by the method shown in FIG. 5B, the support groove 303 of the low-pressure insulator 301 opens in a direction inclined by approximately 45 degrees in the direction of the utility pole 201 with respect to the upward direction. When the low-voltage line 202 is fitted to the support groove 303 in this state and the low-voltage line 202 is placed on the low-pressure insulator 301, the weight of the low-voltage line 202 is applied to the support groove 303 portion of the low-pressure insulator 301 and is separated from the utility pole 201. The tension of the low pressure wire 202 acting in the direction is also applied to the support groove 303 portion of the low pressure insulator 301. The force applied to the bind line 204 that locks and fixes the low-pressure wire 202 to the low-pressure insulator 301 is reduced by the amount of force received by the low-pressure insulator 301. As a result, the bind line 204 is not easily loosened. Even if the bind line 204 is slack, the low-pressure line 202 is kept in the state of being fitted to the support groove 303 by its own weight and tension, so that the low-voltage line 202 is not easily dropped from the low-pressure insulator 301.

  Thus, according to the low-pressure rack 101 of the present embodiment, in the straight street 200 (refer to FIG. 1A), the outer side 102ab of the first arm 102a is placed along the length direction of the utility pole 201, and the low-pressure rack 101 By attaching 101 to the power pole 201, the support groove 303 of the low-pressure insulator 301 opens upward, the low-voltage wire 202 is placed on the low-pressure insulator 301, and the weight of the low-voltage wire 202 applied to the low-pressure insulator 301 is reduced. It becomes possible to make it. Further, according to the low-voltage rack 101 of the present embodiment, in the curved street 200a (see FIG. 1B), the low-side rack 102cy of the connecting member 102c has the outer side 102cb along the length direction of the utility pole 201. By attaching the rack 101 to the utility pole 201, the support groove 303 of the low-pressure insulator 301 opens obliquely upward, and the low-voltage line 202 is fitted in the support groove 303 so that the low-pressure line 202 works in the vertical direction. It is possible to reduce the force applied to the bind wire 204 by applying both of the tensions to the low-pressure insulator 301. That is, according to the low-voltage rack 101 of the present embodiment, the low-voltage line 202 is fixed to the low-voltage insulator 301 for the low-voltage line 202 erected on the utility pole 201 erected on a street of various shapes regardless of straight lines and curves. The bind line 204 can be placed in a situation where it is difficult to loosen.

  Furthermore, according to the low-pressure rack 101 of the present embodiment, even if the bind line 204 is loosened, the low-voltage line 202 is maintained in a state in which the low-voltage line 202 is fitted in the support groove 303. 101 can be prevented from contacting.

  In addition, according to the low-pressure rack 101 of the present embodiment, even when performing a binding operation in which the low-voltage wire 202 is captured and fixed to the low-pressure insulator 301 by the bind wire 204, the worker can reduce the weight of the low-voltage wire 202 by much. Can be received by the low-pressure insulator 301 and the low-voltage wire 202 and the low-pressure insulator 301 can be fixed and fixed more firmly.

  Next, another embodiment will be described with reference to FIGS. In this case, the same portions as those in the embodiment described with reference to FIGS. 1 to 5 are denoted by the same reference numerals, and description thereof is also omitted. A low-pressure rack 101 according to another embodiment of the present invention has two components, a low-pressure rack body 150 and a low-pressure rack adapter 151 connected to each other.

  FIG. 6 is a left side view of the low-pressure rack 101 according to the present embodiment. The low-pressure rack 101 of the present embodiment is configured by connecting and fixing a low-pressure rack body 150 and a low-pressure rack adapter 151.

  Similarly to the low-pressure rack 101 of the above-described embodiment, the low-pressure rack main body 150 is integrally formed in a substantially U shape in side view by connecting the upper ends of the first arm 102a and the second arm 102b to the connection member 102c. Has been. The connecting member 102c is not bent at approximately 45 degrees and is substantially perpendicular to each of the first arm 102a and the second arm 102b. That is, only the flat portion 102 cx is formed on the connecting member 102 c and extends in parallel with the axial direction of the low-pressure insulator 301. And the outer side 102cz of the side wall 104 positioned outside the connecting member 102c has a linear shape. Further, the flat portion 102cx of the connection member 102c is provided with a bolt hole 160a having the same shape as the bolt hole 160b provided in the second side member 153 of the low-voltage rack adapter 151 described later.

  The low-pressure rack adapter 151 includes a first side member 152, a second side member 153, and a third side member 154. The first side member 152, the second side member 153, and the third side member 154 of the low-voltage rack adapter 151 are all wider than the first arm 102a, the second arm 102b, and the connection member 102c of the low-pressure rack body 150. It is a flat plate shape. The second side member 153 has one end connected to the lower end side of the first side member 152, and extends from the first side member 152 perpendicular to the direction in which the first side member 152 extends. The third side member 154 connects the upper end side of the first side member 152 and the other end side of the second side member 153 and is inclined in an acute angle direction with respect to the extending direction of the first side member 152. In the low-voltage rack adapter 151, the first side member 152, the second side member 153, and the third side member 154 are integrally formed to form a substantially right triangle shape in side view.

  The second side member 153 is provided with a bolt hole 160b having the same shape as the bolt hole 160a described above. That is, the connecting member 102c of the low-pressure rack main body 150 and the second side member 153 of the low-pressure rack adapter 151 are connected to the connecting bolt 161 passing through the bolt holes 160a and 160b and the connecting bolt 161, as shown in FIG. The nuts 162 that are screwed together can be connected and fixed with their longitudinal directions aligned.

  In the first side member 152, the second side member 153, and the third side member 154 of the low-voltage rack adapter 151, as in the low-pressure rack 101 of the above-described embodiment, the side edges of both long sides are outside. The side wall 155 is bent and the cross section in the width direction is substantially U-shaped. Further, the outer side of the side wall 155 has a linear shape. Since the first side member 152 and the third side member 154 are connected at an acute angle, the outer side 152 a of the side wall 155 formed on the first side member 152 and the side wall 155 formed on the third side member 154. And the outer side 154a are at an acute angle with each other. The outer side 152 a of the side wall 155 formed on the first side member 152 protrudes from the first arm 102 a of the low-pressure rack 101 in a state where the connection member 102 c and the second side member 153 are connected by the connecting bolt 161 and the nut 162. It is positioned closer to the utility pole 201 than the outer side 102ab of the side wall 104. Therefore, the outer side 152 a of the side wall 155 formed on the first side member 152 serves as a first contact region that can contact along the length direction of the utility pole 201. In addition, the outer side 154 a of the side wall 155 formed in the third side member 154 serves as a second contact region that can contact along the length direction of the utility pole 201.

  FIG. 7 is a schematic diagram illustrating a state in which the low-voltage rack 101 according to the present embodiment is fixed to the utility pole 201. In the method of fixing the low-voltage rack 101 to the utility pole 201 of the present embodiment, the low-voltage rack 101 is fixed to the utility pole 201 in the direction in which the outer side 152 a of the side wall 155 formed on the first side member 152 is along the utility pole 201. The method of directing the support groove 303 of the low-pressure insulator 301 upward (see FIG. 7A) and the low-pressure rack 101 in the direction in which the outer side 154a of the side wall 155 formed on the third side member 154 is along the utility pole 201. There is a method (see FIG. 7B) in which the support groove 303 of the low-pressure insulator 301 is fixed to the utility pole 201 and is directed obliquely upward near the utility pole 201 rather than upward. According to these methods, the low-pressure insulator 301 can be applied with the own weight of the low-pressure wire 202 or the tension of the low-voltage wire 202 acting in the lateral direction, as in the above-described embodiment.

  As described above, the low-voltage rack 101 of the present embodiment also fixes and fixes the low-voltage line 202 to the low-voltage insulator 301 with respect to the low-voltage line 202 installed on the utility pole 201 standing on the streets of various shapes regardless of straight lines and curves.
