Description

ELECTRIC POLE FOR FIXING OVERHEAD WIRE AND HAVING DISTRIBUTION INSULATOR}

The present invention relates to a pole, and more particularly, to a pole with a fixed wire and the distribution wire is implemented to facilitate the change of the position of the light arm without separation of the processing wire process and the distribution insulator.

In general, electricity is an essential means of our lives, and with the development of civilization, the modern society demands high-quality electric power in the times of the past. In order to prevent a power outage, national efforts are being made.

For example, work outages, which accounted for the largest portion, were solved by the development and application of the uninterrupted electrostatic method, and power outages due to poor pressurization were greatly reduced by the development and supply of high-quality materials. It has been resolved to some extent by fire and simple bird-avoidance type lords and remedies. To prevent lightning strikes of the distribution lines, the protection measures of the distribution lines are based on the installation of overhead lines as well as guided lightning protection. In order to solve this problem, a large amount of lightning arresters and the like were installed.

In addition, other blackout accidents are caused by natural disasters such as typhoons and floods, poor customer equipment, errors of the general public, errors of workers, and unknown causes.

On the other hand, the pole is installed on the ground, at least one light arm is installed on the top of the pole. A plurality of insulators are provided on the upper surface or the side surface of the light arm for insulating and supporting the overhead wire.

The electric wire installed in the conventional telephone pole repeats expansion and contraction according to the season. As the temperature drops, the wire contracts and hangs tightly on the poles at both ends. On the contrary, when the temperature rises, the electric wire expands and falls on the telephone poles of both ends. If the wire is stretched on the telephone pole, it will not look good and the strong wind will cause the stretched wire to move. If the sagging wire is constantly moved by strong winds, the insulator supporting the wire may be impacted, causing the insulator to break or cause an accident that can lead to the insulator. Breakage of the insulators prevents the smooth supply of electricity, which can lead to an interruption in the area where the accident occurred. In addition, residents living in the area where the accident occurred can not use the electricity until the maintenance work proceeds, it is not possible to use various electronic devices and electrical devices driven by electrical energy.

Therefore, the light beam is installed at a certain height in the above-mentioned pole, the light support for supporting the wire can be said that the durability and efficiency of maintenance is very important.

However, the conventional light braid is fixed simply by fastening bolts and nuts at a certain height to the pole, and since it does not have a separate support means, when the supported wire becomes loose or too taut, or due to ground subsidence When the position adjustment (vertical direction) is required, there is an uncomfortable problem of disassembling the fastened bolts and nuts, and a separate expensive equipment is required because the light load is completely separated from the pole. The problem of increasing cost and time has arisen.

Is a main cross-sectional view showing a state coupled to the pole 10.

1 and 2, the electric pole 10 according to the present invention includes a pair of semicircular pole pole fixing pieces 21 and 21 fixed to surround the pole pole 10, and a pole pole fixing piece 20. And a pair of semi-circular rotating pieces 30 and 31 installed to surround the outer circumferential surfaces 201 and 211 of the 21 and the semi-circular rotating pieces 30 and 31, respectively, and rotate the rotating pieces 30 and 31. And a plurality of insulators (generally posts) for supporting the overhead wire 60, which are installed or formed to be pulled out of the lightly supported supports 40 and 41 which vertically reciprocate and And insulators 50 including light intensities 403 and 413.

In the electric pole 10, a pair is formed so that the locking grooves 11 and 12 of a predetermined depth are spaced apart at regular intervals along the outer circumferential surface at the height where the light beams 403 and 413 are installed. Therefore, the electric pole fixing piece 20 to be described later may be fixed so that the position is continuously maintained while wrapping the electric pole 10.

The pair of pole fixing pieces 20 and 21 described above is formed in a semicircular shape to surround the pole 10, and when a pair of pole pole fixing pieces 20 and 21 are installed, the pair of pole pole fixing pieces 20 and 21 may be circular. It becomes a shape. In describing the drawings, the pair of pole retaining pieces 20 and 21 each have the same shape, and portions not represented in the drawings are the symbols of one pole fixation piece 20 or the other pole fixation pieces 21. Is quoted in place of. Again, the rotary pieces 30 and 31 and the lightened supports 40 and 41 will also be described in the same manner.

Guide protrusions 203 and 213 protrude from the outer circumferential surface 201 of the pole fixing pieces 20 and 21 along the outer circumferential surface. The guide protrusions 203 and 213 serve to guide the rotation of the rotating pieces 30 and 31 to be described later. In addition, the inner circumferential surfaces 202 and 212 of the pole pole fixing pieces 20 and 21 are paired with the protrusions 204 and 205 to be caught after being seated in the engagement grooves 11 and 12 formed on the outer circumferential surface of the pole pole 10 described above. , 214 and 215 are provided at regular intervals. Therefore, when the pole fixing pieces 20 and 21 are coupled to each other by bolts and nuts by brackets 206 and 216 installed at four corners, the locking projections formed on the inner circumferential surfaces 202 and 212 of the pole fixing pieces 20 and 21 are respectively. 204, 205, 214, 215 caught on the engaging grooves (11, 12) formed on the outer circumferential surface of the pole 10, the pole mounting pieces 20, 21 installed can be tightly fixed to the pole without flowing in the vertical direction will be. This advantage overcomes the conventional technical shortcomings, which can be flowed in the vertical direction as time passes by winding the fastening rope for supporting the light arm to the pole and bolting both ends.

On the other hand, the pair of rotating pieces (30, 31) is installed to surround the outer circumferential surface (201, 211) of the above-described pole pole fixing pieces (20, 21), and after coupling itself rotates in pole pole fixing pieces (20, 21) This is possible. Threads 302 and 312 are formed on the outer circumferential surfaces 301 and 311 of each of the rotary pieces 30 and 31 described above, and levers 305 and 315 protruding outward are provided, respectively. In addition, the guide protrusions 203 and 213 protruding from the outer circumferential surfaces 201 and 211 of the electric pole fixing pieces 20 and 21 described above may be guided to the inner circumferential surfaces 303 and 313 of the respective rotating pieces 30 and 31. Guide grooves 304 and 314 are formed. At the same time, the guide protrusions 203 and 213 and the guide grooves 304 and 314 are formed at the respective outer peripheral surfaces 201 and 211 and the inner peripheral surfaces 303 and 313 of the electric pole fixing pieces 20 and 21 and the rotating pieces 30 and 31, respectively. It is formed in the circumferential direction, and each of the fixed pole and the rotating piece is combined to form a band shape. Therefore, when the rotating pieces 30 and 31 are installed in the pole fixing pieces 20 and 21, the rotating pieces 30 and 31 are formed in accordance with the coupling of the guide grooves 304 and 314 and the guide protrusions 203 and 213. Even when the levers 305 and 315 are rotated by holding the levers 305 and 315, only their own rotation is possible.

On the other hand, the pair of light braid support (40, 41) is a light braid provided to protrude or form a predetermined length on the outside of the semi-circular rotating piece fastening portion (401, 411) and the above-mentioned rotating piece fastening portion (401, 411) (403, 413). As illustrated in FIG. 2, a plurality of insulators (post insulators) 50 are supported by the light braids 403 and 413, and the overhead wires 60 may be supported by the insulators 50 described above. Although only post insulators are shown in the drawing, various insulators such as pin insulators for jumping a neutral wire may be supported by the light braking 403 described above.

The above-described rotating piece fastening parts 401 and 411 are threaded along the inner circumferential surfaces 402 and 412, and a pair of rotating piece fastening parts 401 and 411 are formed by brackets 406 and 416 formed at each corner. Is engaged, the threads formed on the inner circumferential surfaces 402, 412 of the rotating piece fastening portions 401, 411 are screwed into the threads 302, 312 formed on the outer circumferential surfaces 301, 311 of the rotating pieces 30, 31. . Preferably, since the rotary pieces 30 and 31 are interposed between the rotary piece fastening portions 401 and 411 and the electric pole fixing pieces 20 and 21, a separate fixing means may not be provided.

Therefore, the pole pole fixing pieces 20 and 21, the rotating pieces 30 and 31, and the light arm supports 40 and 41 are sequentially assembled to the pole pole 10 and the levers 305 and 315 protruding outward of the pole pole 10. When rotating), only the light arm supports 40 and 41 can be moved in the longitudinal direction (the direction of ② in FIG. 1) along the rotation direction (the direction of ① in FIG. 1).

3 is a view showing a state in which the height of the light support body 40, 42 is adjusted in the pole of FIG. 1 according to the present invention.

Referring to FIG. 3, when it is necessary to change the tensile degree of the processed wire for the change of season or maintenance, the operator rotates the levers of the rotating pieces 30 and 31 installed in the electric pole 10 in a predetermined direction. At this time, since the pole pole pieces 20 and 21 are fixed to the pole pole 10, only the rotary pieces 30 and 31 rotate, and the guides protruded to the outer circumferential surfaces 201 and 211 of the pole pole pole pieces 20 and 31. Since the projections 203 and 213 are guided after they are seated in the guide grooves 304 and 314 formed on the inner circumferential surfaces 303 and 313 of the rotating pieces 30 and 31, the above-described rotating pieces 30 and 31 only rotate by themselves. This is possible and does not move vertically.

According to the rotation of the rotary pieces 30 and 31, the outer circumferential surfaces 301 and 302 of the rotary pieces 30 and 31 and the inner circumferential surfaces 402 of the rotary piece fastening portions 401 and 411 of the light arm supports 40 and 41. , 412 is screwed in, so that only the light support body 40 moves in the vertical direction (arrow direction in FIG. 3).

In the case of FIG. 3, as the levers 305 and 315 rotate, the light support bodies 40 and 41 flow upward. In addition, since the rotary pieces 30 and 31 and the light support body 40 and 41 are in a threaded state, the rotary pieces 30 and 31 may have durability that can be maintained continuously without operating the levers 305 and 315.

This configuration has the advantage of vertically shifting the lightened support by rotating only the lever as compared to the complete dismantling or shifting the position by using expensive equipment to adjust the height of the high load lighter including multiple insulators. Has In addition, this configuration will be very advantageous in the case of Korea where the four seasons are distinctly loosely adjust the tension of the overhead wire in winter or tightly adjust the tension of the overhead wire in summer.

Apparently, there are many different ways to modify these embodiments while remaining within the scope of the claims. In other words, there may be many other ways in which the invention may be practiced without departing from the scope of the following claims.
