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 power transmission line that supplies 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, there is a portion where no tension is applied, so-called “edge line”, as shown by an arrow E in FIGS. 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. Moreover, 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 Japanese Patent Laid-Open No. 10-174236

  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-mentioned document, the wire can be bent gently by supporting 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 realistic to work on a high place working bucket or the like. However, it would be convenient if it would be possible to easily carry out the work of bending the electric wire in the high place from the ground or from the top of the power pole without taking out the high place working vehicle if possible.

  Accordingly, the present invention is lightweight and inexpensive that can be easily engaged with a wire at a high place and curved or the like so that the engagement position with the 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.

The inventions of the wire vendor system to solve the above problems, a pair of engaging portions to be engaged on the peripheral surface and the lower peripheral surface of the electric wire spaced apart greater than the thickness of the wire, the engaging portion vertically A first rod-shaped member formed in a short length to be attached to be separated, a second rod-shaped member formed in a long shape to which the first rod-shaped member is coupled to the distal end side, and sandwiched by the first and second rod-shaped members. and angle setting member capable of setting a corner at an arbitrary angle, a wire vendor device Ru provided with the angle setting member is arranged in juncture connecting the first rod-like member and the second rod-like member On the other hand, the engaging portion is provided with a plurality of attachment points so that the interval can be adjusted at a position away from the connection point of the first rod member with the second rod member, and the first rod member has an extending direction in the extending direction. A slide hole formed in the interior so as to be continuous; A slide groove that is formed narrower than the slide hole that communicates with the id hole and opens to the outside, and an engagement hole that is formed by recessing a plurality of edges of the slide groove. , And the engaging portion projects so that the outer shape is smaller than the engaging hole of the first rod-like member, and one end side passes through the slide groove from the inside of the main body portion. A slide bar facing the inner surface of the slide hole, and a biasing material housed in the main body part and biasing the main body part toward the engagement hole by abutting one end side against the other end side of the slide bar, It is characterized by providing .

In this invention, after positioning an electric wire between a pair of engaging parts of the 1st rod-shaped member connected so that it may become an arbitrary angle at the front-end | tip of a 2nd rod-shaped member, the 2nd rod-shaped member is rotated. By this, the engaging part of the location separated in the length direction of an electric wire is press-contacted so that it may move to the downward direction and the upward direction on the upper peripheral surface and lower surface of the electric wire, respectively. Therefore, it is possible to bend the portion where the engagement portion of the electric wire is pressed.
Further, according to the present invention, it is possible to adjust the separation interval of the engaging portion that is pressed against the electric wire to be bent. Therefore, it is possible to arbitrarily adjust the bending rate and the size of the shape for bending the electric wire.
Furthermore, in this invention, without exchanging the engaging portion that is pressed against the electric wire and bent or the like, the one end side of the slide rod is not pulled out by pulling up the main body portion from within the engaging hole of the first rod-like member. The slide rod can be slid in the slide groove with one end of the slide bar facing the inner surface of the slide hole. Just release the main body at the desired position and move it in the direction of another engagement hole. Positioning. Therefore, the separation interval can be easily adjusted without performing the work of attaching and detaching as in the case where the engaging portion is constituted by a screw.

According to the present invention, with a second rod-like member, with easily adjust the spacing of the engaging portion of the first rod-like member, only operated to pivot the hook to the wire during its is located Thus, the engagement portion can be pressed and bent at different positions of the electric wire in the opposite direction. Therefore, it is possible to easily bend the electric wire with a lightweight electric wire bender device that does not require the use of a hydraulic device, etc., and even an electric wire installed at a high place such as a utility pole can be easily hooked and bent to a desired degree Etc.

Further, a male screw (not shown) on the base end side of a pin (protruding member) 15 longer than the wire diameter d can be screwed into the female screw 12, and the pin 15 is orthogonal to the extending direction. It can be made to stand in the direction to do. That is, the two pins 15 constitute an engaging portion that engages with the upper peripheral surface or the lower peripheral surface of the electric wire D so that the electric wire D can be installed in the interior, and is spaced at an adjustable interval.

  Further, as shown in FIG. 2, the pin 15 to be attached to the short member 11 has conical conical portions 15a and 15b formed on the distal end side and the proximal end side, and rotates as described later. When engaging and supporting D, the distal end side conical portion 15a restricts the electric wire D from escaping and escaping, and the load when rotating the electric wire D in the bending direction is limited to the proximal end side. By receiving at the conical portion 15b, the base end side is prevented from being bent or deformed.

  The elongate member 21 includes a grip portion 22 on the base end side gripped by an operator, and umbrella covers 23 and 24 attached to an intermediate portion, and is entirely made of an insulating material such as plastic. Insulation. The grip portion 22 is provided with a replaceable non-slip material made of a material that is difficult to slip. The umbrella covers 23 and 24 are disposed at two positions on the distal end side and the proximal end side in the intermediate portion, and the umbrella cover 23 on the distal end side drips moisture from the short member 11 side, and the umbrella on the proximal end side. The limit position at which the cover 24 can safely perform work is indicated to ensure safety when working.

In addition, the second facing member 33 is fixed to the distal end portion of the long member 21. As shown in FIG. 3A, the first facing member 32 has a notch 32a that opens from the rear end side toward the center portion, and a normal direction from the bottom portion (center portion) of the notch 32a that projects to the one surface side. And a plurality of protrusions 32b extending to the surface. As shown in FIG. 3 (b), the second facing member 33 includes an insertion hole 33a of a thumbscrew 34 formed in the central portion, and a plurality of second protrusions projecting to one side and extending in the normal direction from the insertion hole 33a. The projection 33b is formed. With this configuration, the Kikuza adapter 31 is faced so that the protrusions 32b and 33b of the first and second facing members 32 and 33 are engaged with each other, and tightened with a thumbscrew 34 penetrating the notch 32a and the insertion hole 33a. Can be linked.

  Thereby, the electric wire bender apparatus 10 inserts the electric wire D installed in high places, such as the utility pole 100 shown in FIGS. 6-9 first, between the pins 15 attached to the short member 11, and the electric wire D's The first and second facing members 32 and 33 of the Kikuza adapter 31 face each other so that the grip portion 22 of the long member 21 can be gripped when the pin 15 is brought close to each of the upper and lower peripheral surfaces. The position to be adjusted is adjusted (adjusting the included angle θ between the short member 11 and the long member 21) and connected by being brought into pressure contact with the thumbscrew 34. Thereafter, for example, as shown in FIG. 4, the grip 22 of the long member 21 is gripped, and the electric wire D at the high position is inserted between the pins 15 of the short member 11 and hooked. When the member 21 is rotated, the member 21 rotates about the upper peripheral surface of the electric wire D with which the upper pin 15 of the short member 11 abuts. Therefore, the lower pin 15 comes into contact with the lower peripheral surface of the electric wire D and moves upward with respect to the upper pin 15 in accordance with the amount of rotation, so that the press contact portion of the electric wire D can be curved. it can.

  At this time, since there is no member at other positions between the pins 15 of the short member 11 and is not obstructed, the electric wire D can be easily inserted and hooked. It can be adjusted by changing the mounting position on the short member 11 according to the size of the curved member to be bent, and there is no need to prepare a plurality of types of members.

Therefore, the electric wire bender device 10 that is light and inexpensive does not require a hydraulic device or the like and does not ride on a bucket or the like for working at high places, so that a desired wire can be obtained by bending the electric wires D at high places from the ground. Can be attached.

Next, FIG. 5 is a figure which shows 2nd Embodiment of the apparatus which applied the electric wire bender apparatus based on this invention. Since the present embodiment is configured in substantially the same manner as the above-described embodiment, the same reference numerals are given to the same configurations, and the characteristic portions will be described.

In FIG. 5, the short member 11 of the present embodiment is formed in a prismatic shape instead of engraving the female screw 12 of the above-described embodiment, and a slide hole 42 that opens at least at the upper end at the center thereof. And a slide groove 43 that communicates with the slide hole 42 and opens to the front side is cut out. The short member 11 is formed with a bottomed cylindrical engagement hole 44 by recessing the edge of the slide groove 43 corresponding to the position where the female screw 12 is formed. Instead of the pin 15, a slide pin (engagement portion) 45 engages with the engagement hole 44.

The slide pin 45 is a cylindrical portion which is formed to be fitted is set to smaller diameter than the engaging hole 44 (the main body) 46, a slide hole 42 while being housed in the cylindrical portion 46 A slide rod 47 that is mounted so that it cannot be pulled out and slides in the slide groove 43, and a spring that is housed in the cylindrical portion 46 and biases the cylindrical portion 46 toward the short member 11 (engagement hole 44) . Material) 48.

  The cylindrical portion 46 is formed with an insertion hole 46a that opens to the end surface on the one end side of the cylindrical shape so that the slide rod 47 can enter or withdraw. The cylindrical portion 46 can be assembled by dividing the slide rod 47 and the spring 48 so that they can be installed.

The slide bar 47 is formed to have a diameter smaller than the groove width of the slide groove 43, and a disk 47 a having a large diameter is fixed to both ends thereof. The slide bar 47 is inserted into the insertion hole 46a to position (stor) one disk 47a in the cylindrical portion 46, and the other disk 47a protruding so as to pass through the slide groove 43 has a short length. The inner surface of the slide hole 42 of the member 11 is faced so as not to be pulled out.

  The spring 48 is housed in the cylindrical portion 46, with one end abutting against the edge of the insertion hole 46 a and the other end abutting against the inside of the disk 47 a of the slide rod 47, thereby The short member 11 (engagement hole 44) is biased.

  Thus, without changing the mounting position of the pin 15 as in the above-described embodiment, the slide pin 45 is pulled away from the short member 11 to be detached from the engagement hole 44 and is slid in the direction of the position to be mounted. The mounting position can be changed by fitting the cylindrical portion 46 into the engagement hole 44 that opens to a desired mounting position, and the distance from the other slide pin 45 can be adjusted.

  As described above, in the present embodiment, in addition to the operational effects of the above-described embodiment, the slide pin 45 for bending the electric wire D can be slid and positioned without performing the attaching / detaching operation like the pin 15. The interval can be easily adjusted.

  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. However, since the electric wire bender device 10 according to the above-described embodiment is lightweight, the electric wire bender device 10 climbs to a utility pole. Needless to say, you can also work.
