Description

  The present invention relates to an electric wire bender device, and more particularly to an electric wire bender device that can easily bend an electric wire installed at a high place such as a utility pole.

  Conventionally, a transmission line for supplying power from a commercial power source is connected within a sleeve cover 103 to a connection wire (interrupt edge line) 102 drawn from a device 101 installed on a utility pole 100 as shown in FIG. Therefore, the power transmission line D itself is bent at a curvature that fits within the holding cover 104. Further, as shown in FIG. 7, in order to hold the electric wire D on the electric pole 100, the electric wire D is bent and connected to the insulator 111 installed on the arm metal 110 of the electric pole 100, or as shown in FIG. In order to branch the electric wire D in a plurality of directions, the electric wire D held by the insulator 111 via the holder 112 is bent after being branched in the cover 114, or as shown in FIG. In order to change this, the electric wire D is also bent and connected to the insulator 111 installed on a different arm 110. 7 to 9, reference numeral 120 denotes a pin insulator that supports the electric wire D so that the electric wire D does not approach the armrest 110, as shown in FIG.

  In such an electric wire D, a portion called a “edge line” where no tension is applied is generated, as shown by an arrow E in FIGS. 8 to 11. Since no tension is applied to this part, it can be installed in a free shape, but since it is charged, it is installed with the necessary separation distance between the wires, arms and support. Has been. In addition, even if it is installed with a proper separation distance at the time of new installation, if it is exposed to wind or the like for a long time, the electric wire may move and come into contact with other electric wires or armbands. In such a case, construction is performed to restore the original state.

Therefore, it is necessary to braze such an electric wire (edge line) so that an appropriate separation distance can be taken between the electric wires, the brace, and the support. As a result, electric wires have become thicker and cannot be bent easily by hand. In addition, since the operation of brazing a charged wire by hand is dangerous, a safe tool that can be remotely operated has been desired. For this reason, various electric wire bender apparatuses are proposed (for example, refer patent documents 1 and 2).
Registered Utility Model No. 3024046 JP 10-174236 A

  However, it is necessary to work on the wires that need to be brazed while observing the positional relationship with other wires or braces depending on the situation. In the wire bender device described in the above document, the wire can be bent gently by supporting the three points, or bend by bending strongly, and bend while correcting at the work site. Can be used.

  However, in the electric wire bender device described in this document, since the portion that bends and bends the electric wire is operated by the hydraulic cylinder, the hydraulic hose has to be hung, resulting in a considerable weight. That is, in order to use such an electric wire bender device at a high place such as a utility pole where electric wires are installed, it is practical to work on a high place working bucket or the like. However, if possible, it would be convenient if it was possible to easily carry out the work of bending the electric wire at a high place from the ground or from the top of the utility pole, without having to take out the aerial work vehicle.

  Therefore, the present invention is lightweight and inexpensive that can be easily engaged with an electric wire in a high place and curved, etc., so that the engagement position with the electric wire can be displaced without using hydraulic pressure or the like. An object of the present invention is to provide an electric wire bender device.

  1st invention of the electric wire bender apparatus which solves the said subject is provided in the position which extended the operation bar attached to the front-end | tip of a long operation rod, and the operation rod attached to this attachment part, and extension of this operation rod An inner engagement portion that protrudes in a direction perpendicular to the wire and engages one of the upper or lower peripheral surface of the electric wire and a position that is separated from the extension line of the operation rod attached to the attachment portion to the left and right And a pair of outer engaging portions that protrude in the same direction as the inner engaging portion and engage with the other of the upper peripheral surface or the lower peripheral surface of the electric wire, one of the inner engaging portion or the outer engaging portion, and the mounting portion A first support member that supports the positional relationship to be fixed, a second support member that supports the other positional relationship of the inner engagement portion or the outer engagement portion, and the first support member and the second support In addition to connecting the members, the internal Screwed mechanism for relatively vertically moving part or the one of the outer engaging portion relative to the other and is characterized in that it comprises.

  In this invention, the inner engagement portion is engaged with one of the upper peripheral surface or the lower peripheral surface of the electric wire on the extension side of the operation rod, and the upper peripheral surface or the lower peripheral surface of the electric wire on the left and right sides of the inner engagement portion. After the outer engagement portion is engaged with the other of the two, the operating rod is rotated to operate the screwing mechanism, whereby the first and second support members are relatively moved up and down to move the inner engagement portion and the outer engagement portion. The positional relationship between the engaging portions can be separated in the vertical direction. Therefore, the middle of the electric wire that is hooked on the pair of outer engagement portions can be hooked on the inner engagement portion to be bent, and the separation interval between the pair of outer engagement portions and the outer engagement portion and the inner engagement can be obtained. The electric wire can be bent to a desired degree according to the separation interval in the vertical direction of the portion.

  In addition to the specific matters of the first invention, the second invention of the electric wire bender device that solves the above-mentioned problems is characterized in that the first support member includes an inner engagement portion disposed on the upper side and an attachment disposed on the lower side. And a male screw constituting a screwing mechanism is engraved on the outer peripheral surface formed in a columnar shape between the inner engagement portion and the attachment portion, while the second support member is a pair of The outer engagement portion of the outer engagement portion is connected while being positioned at a separation position, and a female that constitutes a screwing mechanism on the inner peripheral surface of the through hole that is drilled so as to be continuous in a direction orthogonal to the separation direction of the outer engagement portion. A screw is engraved.

  In this invention, the male screw on the first support member side that supports the inner engagement portion and the female screw on the second support member side that supports the outer engagement portion are screwed together, and the operating rod rotates. When the screwing position is shifted, the positional relationship between the inner engagement portion and the outer engagement portion is separated in the vertical direction. Therefore, according to the rotation of the operation rod, the screwing position of the male screw and the female screw can be shifted so as not to return, and the inner engagement portion and the outer engagement portion are shifted up and down by applying a direct force. However, it is possible to bend the electric wires by separating them with a small force. At this time, the second support member of the outer engagement portion is engaged with two places where the outer engagement portion is separated from the electric wire, so that it rotates together with the first support member due to the rotation from the operation rod. There is no.

  According to a third aspect of the wire bender device for solving the above-mentioned problems, in addition to the specific matter of the second aspect, the mounting portion of the first support member is mounted in the inner engagement while the operation rod is mounted so as not to be relatively rotatable. The support part for supporting the part is characterized in that it is connected and supported coaxially relative to the threaded part in which the male thread is engraved.

  In this invention, the rotation of the operating rod is transmitted and the male screw of the threaded portion is transmitted to the second supporting member without causing the screw portion to rotate relative to the mounting portion of the first supporting member connecting the operating rod. The inner engagement portion that engages with the electric wire can be prevented from rotating relative to the screw portion and coming off the electric wire. Here, the inner engagement portion may be formed in a disk shape extending in the rotation direction, and the engagement state may be maintained even if the inner engagement portion is rotated. It is possible to avoid the sliding contact with the electric wire and deteriorating the coating. Therefore, the wire can be reliably engaged and bent without deteriorating the wire.

  According to a fourth aspect of the electric wire bender device for solving the above-mentioned problems, in addition to the specific matter of the second or third aspect, the second support member is configured to be able to change the mounting position of the pair of outer engagement portions. It is characterized by being.

  In this invention, according to the extent to which the electric wire is bent or the like, the position of the outer engaging portion that engages with the electric wire outside the inner engaging portion can be changed and the interval can be adjusted. Therefore, it is possible to cope with this by simply adjusting the distance between the outer engaging portions without preparing various types of wire bender devices according to the size and angle of bending.

  According to a fifth invention of an electric wire bender device that solves the above-mentioned problems, in addition to the specific matter of any of the first to fourth inventions, one or both of the inner engagement portion and the outer engagement portion is an electric wire. It is comprised by a pair of protrusion member spaced apart up and down by the space | interval which can be equipped internally.

  In this invention, it can be engaged so that a protrusion member may pinch the upper and lower sides of an electric wire. Therefore, the protruding member can be engaged with the electric wire regardless of the direction in which the inner engagement portion and the outer engagement portion move relatively up and down.

  In a sixth invention of the wire bender device that solves the above-described problems, in addition to the specific matters of the first to fifth inventions, one or both of the inner engagement portion and the outer engagement portion are engaged at the tip. It is produced in the shape which protrudes in the electric wire side.

  In this invention, the front-end | tip of an inner engaging part or an outer engaging part protrudes in the electric wire side, and engages with the electric wire. Therefore, when the inner engagement portion and the outer engagement portion are moved relative to each other in the vertical direction and separated from each other, when the force is applied to the wire, the engagement state is maintained without the wire being detached and escaping. be able to.

  According to a seventh aspect of the electric wire bender device for solving the above-mentioned problems, in addition to the specific matter of any of the first to sixth aspects, the inner engagement portion is extended in the extending direction of the electric wire to be engaged. And is made of a plate-like material that curves in the outer peripheral direction of the electric wire.

  In this invention, the plate-like material of the inner engagement portion can be engaged by wrapping the upper peripheral surface of the electric wire along its longitudinal direction. Therefore, it can restrict | limit that an inner engaging part rotates with respect to the extension direction of an electric wire, and can engage an outer engaging part with an electric wire easily.

  According to the present invention, after the operation rod is held and the inner engagement portion and the outer engagement portion are made engageable with the electric wire, the electric wire between the outer engagement portions is engaged by simply rotating the operation rod. The joint portion can be curved by relative movement in the vertical direction, and the vertical movement of the inner engagement portion and the outer engagement portion can be realized by a screwing mechanism. Therefore, it is possible to easily bend the electric wire with a lightweight electric wire bender that does not require the use of a hydraulic device, etc., and to easily hook the electric wire installed at a high place such as a utility pole to bend it to a desired degree. be able to.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, the best embodiment of the invention will be described with reference to the drawings. 1-4 is a figure which shows one Embodiment of the electric wire bender apparatus which concerns on this invention.

  In FIG. 1, an electric wire bender device 10 includes a first support member 11 formed in a substantially I-shape and a second support member 21 formed in a substantially inverted triangle, and is a general-purpose long insulation described later. It is attached to the tip of the operation rod 30 for use.

  The first support member 11 includes a rod-like long portion 12 that is formed in a cylindrical shape and has an external thread 12a engraved on the outer peripheral surface thereof, and a short portion that is connected to the upper portion of the long portion 12 so as to be coaxially rotatable. 13, and a joint (attachment portion) 14 that is fixed to the lower portion of the long portion 12 so as not to rotate and attaches the tip of the insulating operation rod 30.

  As shown in FIG. 2, the long portion 12 is formed in a cylindrical shape in which the end portion connected to the short portion 13 is not formed with the male screw 12 a, and the end portion is continuous in the circumferential direction. A circumferential groove 12b is engraved. The short part 13 has a cylindrical shape with an outer shape, and has a bottomed cylindrical connection in which the columnar end of the long part 12 can be inserted on the end part side connected to the long part 12. A hole 13b is perforated, and a wall surface portion defining the connecting hole 13b can be screwed with an embedded screw 15 at a symmetrical position around the axis, corresponding to the circumferential groove 12b. A female screw 13c is engraved. Thereby, after inserting the end part of the long part 12 in the connection hole 13b of the short part 13, the 1st support member 11 screwed the embedded screw 15 in the female screw 13c of the short part 13, and is long. By entering the circumferential groove 12b at the end of the portion 12, the short portion 13 can be connected to the end of the long portion 12 so that it cannot be pulled out and can rotate coaxially.

  In addition, the short portion 13 is provided with mounting holes 13a of pins (protruding members) 16 longer than the wire diameter d adjacent to each other in the extending direction of the front surface and at positions spaced apart wider than the wire diameter d. The mounting hole 13a is engraved with a female screw that can be screwed into the male screw at the base end of the pin 16. Thereby, it attaches to the front surface of the short part 13 in the state which stands up in the direction orthogonal to a pair of pins 16, and can position an electric wire between the pins 16. FIG.

  That is, the pin 16 of the short part 13 of the first support member 11 constitutes an inner engagement part that separates the electric wire so that the electric wire can be housed and engages the upper peripheral surface or the lower peripheral surface thereof. 13 constitutes a support portion for supporting the pin 16.

  The joint 14 is formed in a bottomed cylindrical shape that opens on the rear end surface side of the long portion 12, and can be attached by inserting the distal end portion of the insulating operation rod 30 from the extending direction of the long portion 12. In addition, a pair of a notch portion 14a cut out toward the insulating operation rod 30 side and a notch portion 14b bent continuously in an orthogonal direction to the notch portion 14a are formed on the peripheral surface portion of the joint 14. The pin 31 of the insulating operation rod 30 can be attached so as not to be pulled out (cannot be dropped off) by entering the hook 31 from the cutout portion 14a to the back of the cutout portion 14b.

  As shown in FIG. 3, the insulating operation rod 30 is attached to a pin 31 to be engaged with the notches 14 a and 14 b of the joint 14, a proximal end side grasping portion 32 grasped by an operator, and an intermediate portion. Umbrella covers 33 and 34, which are made entirely of an insulating material such as plastic to ensure insulation.

  The pin 31 is provided opposite to the side surface of the tip of the insulating operation rod 30 and is fixed in a protruding shape on the opposite side to enter the two cutout portions 14a and 14b of the joint 14 and engage. Can be combined. The grip portion 32 is provided with a replaceable non-slip material that is difficult to slip. The umbrella covers 33 and 34 are disposed at two positions on the distal end side and the proximal end side in the intermediate portion, and the umbrella cover 33 on the distal end side drops moisture from the first support member 11 (electric wire bender device 10) side. In addition, the umbrella cover 34 on the base end side indicates the limit position where the work can be performed safely, and the safety during the work is ensured.

  Here, after the insulating operating rod 30 is rotated by causing both the pins 31 to enter the notches 14a and 14b of the joint 14 while sinking the protrusion 35 at the tip against the elastic force of the built-in spring. When the force to be entered is released, the projection 35 protrudes due to the elastic force of the spring and pushes out the joint 14, whereby the pin 31 can be engaged in the engagement groove 14c bent from the notch portion 14b in a non-detachable manner. it can. Further, the insulating operation rod 30 is rotated so that the grip 36 screwed into a screw shape engraved at the center portion is rotated toward the joint 14 so that the pin 31 is not detached from the engagement groove 14c and does not rotate. The insulating operation rod 30 can be handled while reliably preventing the first support member 11 (the wire bender device 10) from rotating and disengaging with high reliability.

  On the other hand, the second support member 21 has an inverted triangular bottom 22 formed in a cylindrical shape and is screwed into the inner peripheral surface of the through hole with the male screw 12a of the long portion 12 of the first support member 11. A female screw 22a is engraved. In addition, a pair of mounting holes 23a into which the pins 16 can be screwed are formed on the upper side 23 of the inverted triangle of the second support member 21 similarly to the short portion 13 of the first support member 11 from both ends. It is engraved at four intervals. Here, it is needless to say that the setting locations of the mounting holes 23a for attaching the pins 16 are not limited to four equally spaced locations, and can be arbitrarily set according to the size of the wire to bend in order to bend the wires. What is necessary is just to set to a space | interval and a location.

  That is, the pin 16 of the upper side portion 23 of the second support member 21 protrudes in the same direction as the pin 16 (inner engagement portion) of the short portion 13 of the first support member 11 so that the electric wires can be separated. Thus, an outer engaging portion that engages with the upper peripheral surface or the lower peripheral surface is configured, and the mounting holes 23a are arranged at a plurality of locations so that the separation interval can be adjusted by changing the mounting position of the pin 16. Is set to Further, the first and second support members 11 and 21 are configured such that the male screw 12a of the long portion 12 and the female screw 22a of the top portion 22 are screwed together, whereby the pin 16 of the short portion 13 and the pin 16 of the upper side portion 23 are engaged. And the joint 14 (insulating operation rod 30) below the long portion 12 can be positioned and fixed, and by rotating the joint 14 (insulating operation rod 30) while restricting the rotation of the upper side 23. The pin 16 of the short portion 13 can be moved up and down relatively with respect to the pin 16 of the upper side portion 23 by changing the screwing position.

  When the second support member 21 is assembled by screwing the male screw 12a of the long portion 12 of the first support member 11 into the female screw 22a of the top portion 22, the head of the short portion 13 is the upper side portion. The central portion 23 b of the upper side portion 23 is along the rectangular outer surface of the short portion 13 (first support member 11) on the back side of the pin 16 so that it does not come into contact with the central portion 23 b of the pin 23 and is blocked. Thus, it is formed in a shape that bypasses the U-shape.

  As a result, the electric wire D installed at a high place such as the utility pole 100 shown in FIGS. 2 When the insulating operation rod 30 is rotated while being inserted between the pins 16 attached to the support members 11 and 21, the male screws 12a of the first and second support members 11 and 21 and The screwing position of the female screw 22a shifts and moves up and down relatively. Therefore, for example, when the first support member 11 is lowered with respect to the second support member 21, the left and right lower pins 16 of the second support member 21 are separated from the lower peripheral surface of the electric wire D as shown in FIG. 4. While abutting and supporting, the pin 16 of the first support member 11 descends while abutting and supporting the upper peripheral surface of the electric wire D therebetween. In this case, in a state where the left and right pins 16 of the second support member 21 are hooked on the separated portion of the electric wire D, the pin 16 of the first support member 11 hooked therebetween is pulled down (displaced), and the electric wire D Can be curved downward.

  At this time, in the first support member 11, the long portion 12 rotates integrally with the insulating operation rod 30 attached to the joint 14 on the lower end side, whereas the short portion 13 is on the upper end side of the long portion 12. While being relatively rotatable, the female screw 22a of the second support member 21 is screwed onto the male screw 12a of the elongated portion 12. For this reason, even if the short part 13 and the second support member 21 do not rotate integrally with the long part 12, the short part 13 and the second support member 21 try to rotate with the rotation of the insulating operation rod 30 connected to the long part 12.

  However, the short portion 13 can be moved up and down while pressing the plane of the prismatic front surface against the electric wire D, and the pin 16 standing on the front surface is kept hooked without coming off the electric wire D. can do. Moreover, the 2nd support member 21 can press the upper side part 23 against the electric wire D, and can maintain the state hooked without the pin 16 standingly arranged in the front surface removing from the electric wire D.

  In addition, since the first and second support members 11 and 21 maintain the mutual positional relationship with the male screw 12a and the female screw 22a, the reaction force from the curved electric wire D is applied to the pin 16. In addition, the insulating operating rod 30 is not rotated in the opposite direction, and the electric wire D can be bent so that the insulating operating rod 30 is gradually rotated with a small force so that a desired wrinkle is attached.

  Here, the distance between the pins 16 of the second support member 21 can be adjusted by changing the position where the pins 16 are attached to the attachment holes 23a of the upper side portion 23 in accordance with the magnitude of the curvature for attaching the wrinkles to the electric wires D. And there is no need to prepare multiple types of members.

  In addition, since the pins 16 of the first and second support members 11 and 21 are attached so as to be paired up and down, the electric wire D positioned between them by rotating the insulating operation rod 30 in the forward and reverse directions. Can be curved in either the top or bottom direction. Further, the pin 16 is simply screwed into the mounting holes 13a and 23a, and one or both of the first and second support members 11 and 21 are attached to the upper or lower peripheral surface of the electric wire D. Only the lower side or the upper side to be brought into contact with each other can be provided, and in this case, the electric wire D can be easily positioned by greatly separating the vertical interval of the pins 16.

  As described above, in the present embodiment, the wire bender device 10 capable of moving the first and second support members 11 and 21 up and down by the screwing mechanism of the male screw 12a and the female screw 22a is attached to the insulating operation rod 30. The pin 16 hooked on the electric wire D is moved up and down simply by rotating the insulation operating rod 30 with the pin 16 of the first and second support members 11 and 21 hooked on the electric wire D at a high place. The electric wire D can be easily bent. Accordingly, the electric wire D at a high place can be easily bent from the ground by the light and inexpensive electric wire bender device 10 without requiring a hydraulic device or the like and without riding on a bucket for working at high places. Can be attached.

  As a first other aspect of the present embodiment, instead of the pin 16 of the present embodiment, a pin 46 shown in FIG. 5 is attached to the short portion 13 of the first support member 11 or the upper side portion 23 of the second support member 21. You may make it attach by screwing in the formed attachment holes 13a and 23a. The pin 46 is formed in a T shape projecting in the vertical direction with the distal end facing the short portion 13 and the upper side portion 23, and the proximal end is formed in a conical shape. By configuring in this way, the pin 46 can maintain a state in which the electric wire D is prevented from coming off by the protruding portion 46a on the distal end side, and can be kept hooked. By receiving the load when moving up and down in the bending direction at the conical portion 46b on the base end side, it is possible to avoid the base end side from being bent or deformed.

  As a second other aspect of the present embodiment, the pin 56 shown in FIG. 6 is replaced with the short portion 13 of the first support member 11 or the upper side portion of the second support member 21 instead of the pin 16 of the present embodiment. 23 may be screwed into the mounting holes 13a and 23a formed in the head 23. The pin 56 is formed in a shape that curves toward the electric wire D side with the distal end side positioned therebetween, and the proximal end side thereof is formed with a large diameter. With this configuration, the pin 56 can maintain the hooked state by restricting the electric wire D to be hooked from the curved shape portion 56a and trying to move the pin. By receiving the load at the time of moving up and down in the bending direction by the large-diameter portion 56b on the base end side, it is possible to avoid deformation such as bending of the base end side.

  As a third other aspect of the present embodiment, the pin 66 shown in FIG. 7 is screwed into the mounting hole 13a formed in the short portion 13 of the first support member 11 instead of the pin 16 of the present embodiment. You may make it attach. The pin 66 is extended in the extending direction of the electric wire D, and a curved plate 67 that is curved along the outer peripheral surface of the electric wire D is fixed, and the base end side is formed in a conical shape. Yes. By configuring in this way, the pin 66 can be supported and hooked so that the upper peripheral surface side or the lower peripheral surface side of the electric wire D is wrapped by the curved plate 67, and the pin 66 tries to rotate as the insulating operation rod 30 rotates. It is possible to maintain the hooked state without restricting the operation by the electric wire D itself. Further, the pin 66 is prevented from being deformed, for example, the base end side is bent by receiving the load at the time of moving up and down in the direction in which the electric wire D is hooked and bent in the base end side conical portion 66b. Can do.

  Although one embodiment of the present invention has been described so far, it is needless to say that the present invention is not limited to the above-described embodiment, and may be implemented in various forms within the scope of the technical idea. For example, in the above-described embodiment, a case where a desired wire is attached by bending the high-level electric wire D from the ground will be described. Needless to say, you can also work.
