Description

Cable Support Device Of The Telegraph Pole For Supply Of Electric Power}

The present invention relates to a wire support device for distribution poles, and in particular, when external force is generated by inserting a support member capable of supporting a high voltage cable in a rectangular bar disposed on the left and right sides of a cap covered on the top of the pole for stable support of the high voltage cable. The present invention relates to a wire support apparatus for power distribution poles which prevents safety accidents in advance by securing and providing a solid support force against radially acting external force.

In general, when looking at the path of power, the power plant transmits high-voltage power to each substation through the transmission line of the transmission tower, and then performs a multi-stage transformation process. To feed.

Therefore, by installing a support (called hard light) on the top of the pole, it is fixed by connecting the high-voltage cables.

The light arm is installed on top of the pole is to enable the construction of wire cable by fastening a plurality of suspension insulators and support insulators to the pole, the light arm is arranged on both sides of the pole, separate "U" shaped Wrapping the pole with a binding hole (hereinafter referred to as “U” type bolt) and binding it through the light arm, and install and fix it to the pole with the fastening nut.

However, since the conventional light arm mounting structure is simply a structure supported by a "U" type fastener, when the fatigue load caused by the electric wire cable is continuously applied to the fastener, the binding force with the light arm is lowered. The phenomenon that the gold falls to the bottom occurs, which is a structure that leads to a significant decrease in the bearing capacity of the high-voltage cable, which eventually triggers a safety accident, and the number of light weights installed in one binding means is limited. There is a difficult problem in construction because a large number of fasteners are required when installing a plurality of light wrists, and such a conventional light arm fastening structure includes a structure in which jumper wires connecting high voltage cables swing around in the influence of the wind. As a result, the connection with the high voltage cable is lost.

Patent registration No. 10-818556 (Patent Document 1) has been proposed as a way to solve the conventional problems, but the pair of upper and lower front and rear prevention zones of the left and right diameter brace is a high-voltage cable that always requires tension from the line post insulator It is a part to be connected to both sides, and the force corresponding to the tensile force is largely required, whereas the shape of the support is formed in the direction perpendicular to the direction of the high-tension cable tension, so the elastic support of the support alone is not sufficient to handle the unexpected external force. Because of its weakness, when the unexpected external force is applied to high voltage cable or telephone pole, its mechanical strength alone does not guarantee stable support.

Such unexpected external force can occur in various ways. For example, a high-ladder vehicle for moving a vehicle loses its center when the ladder is lifted and overturns a safety accident that covers a high-voltage cable by surrounding buildings or telegraph poles. It is not easy to prevent an accident in advance because the force direction of the external force acts radially in case of accidents that involve telephone poles and inequality in the ground where telephone poles are installed.

In order to solve the above problems, the Utility Model Registration No. 20-0445770 (Patent Document 2) and the Registration Utility Model No. 20-0445769 (Patent Document 3) filed by the same applicant have been proposed.

The technology of Patent Document 2 and Patent Document 3, when the external force is generated, forming a rhombus in preparation for the external force and the distribution including a light braided upper and lower front and rear prevention zone is formed so that the high-voltage cable is installed on both sides of the top and bottom of the rhombus In providing the upper support while providing an elastic means to absorb the impact of external force on the upper support in the upper and lower front and rear prevention jaw provided at equal intervals between each outer surface, support bars having male threads on both sides edge, the support A spring stay formed through the bar close to the engaging jaw and formed with a release prevention jaw at the edge of the edge, and a female thread portion screwed with the male screw portion of the support bar in a direction facing the spring stay. In the gap between the cap nut and the spring stay and the cap nut In order to provide the elastic force against the tension force applied to the upper and lower front and rear prevention zones, the flexible rubber material and the elastic spring, which are combined, are installed in the upper and lower front and rear prevention zones to provide a firm support force of the high-voltage cable against external forces. Secured,

Cross section between upper and lower prevention zone and rhombus is weak. Of course, it is possible to absorb some of the impact of the external force by the elastic means installed in the upper and lower front and rear zones, but the upper and lower front and rear guards facing each other at a distance between the rhombuses and one intersection does not respond properly to the generated external force breakage This often happens.

In addition, since the external force does not act only in a constant direction, but in a radial irregular direction, there is a limit in absorbing shock only by tension means installed in the upper and lower front and rear prevention zones.

Hereinafter, the electric wire support device for power distribution poles according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figures 1 to 4, the present invention is to cover the cap portion 10 formed with a rectangular bar (10a) in the left and right direction to the upper end of the pole pole rectangular bar (10a) arranged in the left and right in a fastening state fixed with a bolt In the insertion of the support member 20 having the 'H' shape in the hollow hollow 23 of the center shape is inserted into the rectangular bar (10a) is inserted into the fastening hole 24 by a bolt inserted into the support member The fixing of (20) can be achieved even when the external force is generated.

The support member 20 forms each of the binding pieces 21 facing each other while being spaced apart from each other in the upper and lower parts on the basis of the hollow 23, and the opposite binding pieces 21 are multi-stage in the high-voltage cable 41. Suspension insulator 40 is connected to the front and rear to form a fixed by fastening bolts.

Each of the binding pieces 21 of the upper and lower sides opposed to the hollow 23 has an opposing surface, that is, an inner surface of which forms a recessed rounded portion 22, and forms an arc shape, and each of the binding pieces ( An outer surface and an inner surface of 21) form a long hole 22a through which the hole is transversely formed.

Therefore, an elastic means capable of absorbing an external force shock is provided at each of the long holes 22a of the opposed binding pieces 21. To be more specific, rods are formed at the respective long holes 22a of the binding pieces 21. 30 is inserted, and the rod 30 has two stepped portions 31, two fastening portions 32, and two elastic springs 33.

One of the stepped portions 31 of the two stepped portions 31 is the inner surface of any one of the binding pieces 21 of the opposed binding pieces 21, that is, fixed to the recessed rounded portion 22 and The other stepped part 31 is fixed to the recessed rounding part 22 which is the inner surface of the other binding piece 21.

Hereinafter will be described the operating state of the present invention according to the external pressure generation.

Unexpected external force is generated. For example, a high-ladder vehicle for moving a vehicle loses its center when lifting a ladder, and is overturned to cover a high-voltage cable by surrounding buildings or telephone poles. In case of accidental settlement and uneven settlement in the ground where telegraph pole is installed, the direction of external force is acting in a radial and irregular direction. At this time, the external force is transmitted to the high-voltage cable 41, and the external force is also transmitted to the support member 20 that supports the suspension insulator 40 so that the opposite binding pieces 21 of the support member 20 reduce the irregular strength of the external force. And control.

Looking in more detail, as shown in Figures 4 and 5, each of the elastic spring 33 installed in the long hole 22a of the opposed binding piece 21, the instant of the opposite binding piece 21 reacts by an external force Absorbs the impact due to refraction, and at the same time, the rod 30 is transverse to the binding piece 21 opposite to what is intended to move by an external force impact force acting in the diagonal direction or the vertical drop direction, which is, for example, a radial direction. By the long hole 22a formed in the above, the movement force of the rod 30 to be moved in the diagonal direction or the vertical drop direction by allowing the movement in the left and right directions is first attenuated, and at the same time, the stepped portion fixed to the rod 30 The depression rounding portion 22 controls that 31 is an inner surface of the binding piece 21 opposed by the left and right movement directions of the rod 30, that is, the movement is to be moved in the left and right directions along the depression rounding portion 22. External force by secondly damping the moving force of the stepped part 31 The effect of the intensity decay is able to achieve.

That is, the stepped portion 31 fixed to the rod 30 by the movement force of the rod 30 to move in the left and right moving direction of the long hole 22a also tries to achieve the left and right movement of the recessed rounding portion 22, but As the directional movement is achieved, the recessed rounded portion 22 has an arc shape, thereby controlling the lateral movement of the stepped portion 31 by increasing the round inclination angle.

Thus, the electric wire support structure of the electric power distribution pole according to the present invention, while the external force generated unexpectedly, attenuates both the movement force of the rod 30 and the movement force of the step portion 31 at the same time, and firmly responds to the external force. Securing support has the effect of preventing accidents in advance.
