Abstract

The present invention relates to an electric pole for controlling a position of an electric power line, which is capable of more easily performing a position control operation by raising a light weight buffer material installed on the electric pole for an electric power line, or capable of supporting the light weight buffer material while rising the light weight buffer material. According to the present invention, when the light weight buffer material is positioned, the position control operation is performed in state that the light weight buffer material is raised by a retractor, so that the light weight buffer material is prevented from falling down even though a coupling bolt fixing the light weight buffer material is released. Thus, a worker can perform the position control operation of the light weight buffer material with both hands, so that the position control operation can be very easily performed, and the working time can be reduced. When the position of the light weight buffer material is changed, the worker moves the light weight buffer material by using the retractor without directly raising the light weight buffer material, so that the worker can easily perform the operation. In addition, after performing the position control operation, the light weight buffer material is supported while being pulled upwardly, so that the light weight buffer material can be prevented from drooping due to the weight of the light weight buffer material. An electric pole for controlling a position of an electric power line according to the present invention includes: an electric pole having a tapered cylindrical shape to have a diameter which is gradually decreased downwardly (in the gravity direction); a light weight buffer material elastically pressed on an outer surface of the tapered electric pole and having an insulator for supporting the electric power line; and a retractor fixed to the electric pole to raise the light weight buffer material.

Description

BACKGROUND OF THE INVENTION Field of the Invention [0001]

The present invention relates to a telephone pole for controlling the position of a distribution line, and more particularly, it is possible to conveniently change the position of a distribution line while firmly fixing a distribution line. Also, The present invention relates to a telecommunication pole for position control of a distribution line that can be installed with a pulling mechanism to make the position adjustment operation more convenient, and after the position adjustment, .

Generally, a telephone pole supports electric wires that connect with power stations and substations, and guides electric wires to places where electricity is required, such as a home or a company.

However, since the electric wire runs at a relatively high voltage, it may be short-circuited through the insulated electric pole. Therefore, in order to minimize the possibility, the electric wire should be fixed by insulator excellent in insulation so that the wire and the wire do not come into direct contact with each other. These insulators are called insulators.

FIG. 1 is a view showing a conventional electric pole, FIG. 2 is a view showing a light pole 120 for a pole of the pole of FIG. 1, and FIG. 3 is a sectional view of a main part of a pole of the pole with respect to the S-S line of FIG.

1 to 3, the insulator 123 is fixed to the light guide 120 and the light guide 120 is fixed to the pole 110 via belts 125 and 126. [

The light guide 120 has a cantilever type horizontal support 121 fixed to the pole 110 through a first belt 125 and a horizontal support 121 fixed to the pole 110 via a second belt 126, (Gravity direction) deflection of the support base 121. The support base 122 has a support base 122 for supporting the support base 121 in a downward direction.

The insulator 123 is fixed on the horizontal support 121 of the light guide 120 and the power line 130 is fixed to the insulator 123 so that the insulator 123 is not directly contacted to the power pole 110, It is exactly fixed.

The horizontal support 121 is deformed downward due to the weight of the distribution line 130 fixed to the insulator 123. The support support 122 includes a horizontal support 121 and a second belt 126 And the screws 131 and 133 are combined to solve this problem.

The first belt 125 has one end 1251 and the other end 1252 coupled to the hinge 127 and the other end 1252 can be opened and closed in the horizontal direction from the one end 1251. The second belt 126 can be coupled to the one end 1261 and the other end 1262 with the hinge 128 and the other end 1262 can be opened and closed from the one end 1261. [ Holes 1321 and 1322 are formed at the ends of the one end 1251 of the first belt 125 and the ends of the other end 1252 of the first belt 125. The operator inserts the first belt 125 into the pole 110 The first belt 125 can be fixed to the main body 110 by engaging the rear holes 1321 and 1322 with the screws 132. [ Holes 1331 and 1332 are formed at the ends of the one end 1261 and the other end 1262 of the second belt 126 respectively and the worker moves the second belt 126 to the pole 110, The second belt 125 can be fixed to the pole 110 by engaging the holes 1331 and 1332 with the screws 133. [

3, the main body 110 has a tapered shape having a larger diameter as it goes downward, while the first belt 125 and the second belt 126 have a non-tapered cylindrical shape And has a structure optimized to be closely fixed to the body. Therefore, when these belts 125 and 126 are fixed to the mains 110, there is a gap C between the belts 125 and 126 and the mains 110, 110) and the support base (120).

Also, the conventional method of fixing the distribution line 130 to the mains 110 using the light guide 120 is troublesome in changing the fixing position of the distribution line 130. [ For example, the operator can remove the first belt 125 and the second belt 126 from the pole 110 and then fasten the first belt 125 and the second belt 126 back to desired positions on the pole 110 And the gap between the first belt 125 and the second belt 126 is regulated so that the slope of the horizontal support 121 is adjusted.

In order to solve such a problem, a telephone pole for controlling the position of a distribution line of a domestic patent No. 10-1175315 (hereinafter referred to as "prior art") has been proposed.

According to the prior art described above, the light ends of the light poles, which are resiliently pressed on the tapered outer peripheral surface of the electric pole and are provided with insulators for supporting the distribution line, and the holes formed at both ends are screwed together, The power distribution line can be firmly fixed with the belt provided with the elastic repulsive force for the light armature to easily change the position of the power distribution line and can be firmly fixed to the electric pole by its own structure of the light arm.

However, in the above-described prior art, when the screw of the belt fixing the light guide is loosened to adjust the position of the distribution line, the light guide falls down due to its own weight, so the operator must hold the light guide in one hand, To unscrew the belt. Therefore, the worker has to unlock and tighten the screw of the belt with one hand, so that the position adjustment of the light arm is very troublesome and takes a long time.

In addition, since the operator must directly lift or lower the light arm when changing the position of the light arm, there is a problem that it is very difficult to work with the force in a state where the electric pole is high and the posture is unstable.

The present invention uses prior art No. 10-1175315. Therefore, the basic structure of the electric pole for controlling the position of the distribution line described below is all described in the registered patent No. 10-1175315.

However, the present invention further includes the structure of the pulling device 300 for lifting the light guide 220 installed in the telephone pole 210 among the structures disclosed in the Japanese Patent No. 10-1175315, Thereby achieving a constitutional characteristic.

Therefore, the device structure, characteristics, and operation relationship described below are mostly cited in the description of the similar structure among the contents of the above-mentioned Japanese Patent No. 10-1175315, and the detailed description related to the main features of the present invention .

4 to 6, the electric wire 210 for controlling the position of the distribution line according to the present invention has a tapered cylindrical shape whose diameter decreases toward the upward direction. According to the present invention, the tapered outer circumferential surface 211 of the telescope 210 is provided with a light-weighted joint 220 to be fixed by being elastically compressed.

The light guide 220 has a plurality of insulators 225 for fixing the distribution line 250. The insulator 225 refers to a connection member having excellent insulation so that the electric pole 210 and the distribution line 250 are not in direct contact with each other. For example, it is preferable to use a self-polymer material as the insulator 225.

In addition, the light guide plate 220 is installed so as to surround the phone main body 210, and then generates an elastic repulsive force of the light guide plate 220 relative to the phone main body 210.

[ For example, the operator can rotate the light guide 220 along the outer peripheral surface 211 of the electric telephone 210, move it up and down with the tightening bolts 231 released, The fastening bolts 220 can be securely fastened by tightening the fastening bolts 231 again.

In addition, the present invention can change the position of the distribution line 250 without using the light guide 220. That is, by inserting the fixing nut 226 mounted on the vertical axis 225a of the insulator 225, the insulator 225 is rotated or horizontally moved along the slot 223b, So as to have a buffer function as well as a positional change with respect to the path 250.

Therefore, by rotating the circular handle 353, rotational power is transmitted to the driving gear 352, the driven gear 332, and the pulling roller 333 so that the wire 340 can be unwound or wound. At this time, it is preferable that the circular handle 353 is formed to have a larger diameter than the driven gear 332 and the driven gear 352 to minimize the force required to rotate the circular handle 353.

The traction device 300 of the present invention includes a locking mechanism 400 installed between the inner wall of the protection box 320 and the second horizontal axis 351 to selectively fix the second horizontal axis 351 to prevent rotation, As shown in FIG.

9A and 10, the lock mechanism 400 includes a rotary plate 410 fixed to the second horizontal shaft 351 and rotated together with the rotary gear 352 and the circular handle 353, And a lock lever 430 installed on the inner wall of the box 320 so as to be rotatable about the center pin 420.

A plurality of locking grooves 411 are formed in the rotation plate 410 along the outer circumference and a locking pin 431 which is engaged with the locking groove 411 of the rotation plate 410 at one end And a handle 432 is provided at the other end of the lock lever 430 so that the locking position where the locking pin 431 is held by the locking groove 411 and the locking pin 431 are separated from the locking groove 411 As shown in Fig.

The first and second tension coil springs 441 and 442 are provided on the lock lever 430 so that one end of the first and second tension coil springs 441 and 442 is fixed to the lock lever 430, 430).

First and second elastic adjustment pins 443 and 444 are fixed to the other ends of the first and second tension coil springs 441 and 442. The first elastic adjustment pins 443 are formed on the inner wall of the protective box 320 The second elastic regulating fins 444 are inserted into the first or second unlocking holes 453 and 454 formed in the inner wall of the protective box 320. The first and second elastic regulating fins 444 and 442 are inserted into the first or second lock holes 451 and 452,

At this time, the positions of the first locking hole 451 and the first unlocking hole 453 are positioned farther away from the lock lever 430 than the positions of the second locking hole 452 and the second locking hole 454 So that the elasticity of the first and second tension coil springs 441 and 442 can be adjusted.

The second horizontal shaft 351, the circular handle 353, and the second rotary shaft 410 are fixed by inserting or separating the retaining pins 431 of the lock mechanism 400 into the retaining grooves 411 of the rotary plate 410, And the rotation of the traction roller 333 are artificially locked or unlocked.

Accordingly, the operator does not have to hold the light guide 220. Therefore, the operator can work to unfasten and fix the fixing bolt 231 of the light guide 220 using both hands and to fix the light guide 220 to the outer periphery of the pole 210 It is possible to conveniently carry out an operation of rotating the movable member 211 along its axis to change its position.

When opening the door 321 of the protective box 320 and rotating the circular handle 353 clockwise or counterclockwise in order to move the light guide bars 220 up and down, The driving gear 352 fixed to the driven gear 351 is rotated so that the driven gear 332 engaged with the driven gear 352 rotates and the pulling roller 333 fixed together with the first horizontal shaft 331 .

Accordingly, the wire 340 can be unwound or wound along the direction of rotation of the pulling roller 333, so that the light arm 220 can be moved upward and downward while being pulled, Since the light guide 220 can be pulled upward by using the pulling device 300 even after the position of the light guide 220 is changed, the light guide 220 can be firmly fixed and prevented from sagging due to its own weight .

At this time, by the lock mechanism 400 provided in the traction device 300, the rotation of the second horizontal shaft 351 is selectively locked or unlocked, and the light guide poles 220 are pulled and moved up and down Or can remain pulled from the stop position.
