도 7a 내지 도 7c는 본 발명에 따른 클램프활용 안전형 가공배전선 고정장치의 작용효과를 설명하기 위한 도면으로서, 이를 참조하여 설명하면 다음과 같다.7A to 7C are views for explaining the operation and effect of the safety type overhead distribution line fixing device using clamps according to the present invention, and will be described with reference to them.

도 3을 참조하여 애자유닛(200)에 애자클램프(400)를 설치하는 과정에 대해 설명하면, 먼저 제1지지체(410)와 제2지지체(430)를 리벳의 축을 중심으로 벌려 준 다음 애자유닛(200)에 배치한다.Referring to FIG. 3, the process of installing the insulator clamp 400 to the insulator unit 200 will be described. First, the first support 410 and the second support 430 are spread around the axis of the rivet, and then the insulator unit Place it at (200).

그 다음 애자유닛(200)의 제1바디(211)가 제1지지체(410)의 제1반원판(411)과 제2반원판(412) 사이, 제2지지체(430)의 제3반원판(431)과 제4반원판(432) 사이에 각각 배치되도록 한 상태에서 제1지지체(410)와 제2지지체(430)를 오무려주면, 감착홈(411a,412a,431a,432a)이 결합홈(211a)에 삽입되면서 제1지지체(410)와 제2지지체(430)가 원판형태를 이루게 된다.Then, the first body 211 of the insulator unit 200 is between the first semi-disc 411 and the second semi-disc 412 of the first support 410, the third semi-disc of the second support 430 When the first support 410 and the second support 430 are closed in a state in which they are disposed between the 431 and the fourth semi-disc 432, the mounting grooves 411a, 412a, 431a, and 432a are coupled. While being inserted into the groove 211a, the first support 410 and the second support 430 form a disk shape.

상기와 같이 결합한 상태에서 제1지지체(410)의 고정부(411b,412b)와 제2지지체(430)의 고정부(431b,432b)에 볼트(B)와 너트(N)를 각각 체결하여 제1지지체(410)와 제2지지체(430)가 벌어지지 않게 고정한다.In the coupled state as described above, bolts B and nuts N are fastened to the fixing parts 411b and 412b of the first support 410 and the fixing parts 431b and 432b of the second support 430, respectively. The first support 410 and the second support 430 are fixed so that they do not spread.

한편, 도 7a와 같이 설치된 상태에서, 상기 애자유닛(200)에 외력이 가해지게 되면, 애자유닛(200)에서 가장 취약한 부분인 크랙유도홈(212a)에서 크랙발생이 일어나게 되며, 도 7b에 도시된 바와 같이, 여기에 가공배전선(L)이 잡아당기는 인장력이 더해지면서 크랙(균열)은 급속도로 이루어지게 되면서 결국 제2바디(212)는 파단된다.On the other hand, when an external force is applied to the insulator unit 200 in the installed state as shown in FIG. 7A, cracks occur in the crack guide groove 212a, which is the most vulnerable part of the insulator unit 200, as shown in FIG. 7B As described above, as the tensile force of the overhead power distribution line (L) is added to this, cracks (cracks) are rapidly formed, and eventually the second body 212 is broken.

도 7c에 도시된 바와 같이, 상기 제2바디(212)의 파단으로 인해 절연애자(210)의 제2바디(212)는 파단된 면을 기준으로 상호 이격되며, 이에 따라 절연애자(210)의 타측에 고정된 제2지지체(430) 역시 연결봉(420)을 따라 슬라이드 이동되어 고정너트(440)에 걸림된다.As shown in FIG. 7C, due to the fracture of the second body 212, the second bodies 212 of the insulator 210 are spaced apart from each other based on the fractured surface, and accordingly, the The second support 430 fixed to the other side is also slid along the connecting rod 420 and is caught by the fixing nut 440 .

이때, 상기 절연애자(210)가 외력에 의해 파단되더라도 애자클램프(400)의 제1지지체(410)와 제2지지체(430)가 연결봉(420) 및 고정너트(440)를 매개로 상호 연결되어 절연애자(210)를 감싸서 고정하고 있기 때문에 절연애자(210)의 분리 및 이로 인한 추락사고를 최대한 늦출 수 있다는 점에서 안전사고를 지연할 수 있으며, 이에 따라 작업자는 신속한 후속조치를 실시할 수 있는 이점이 있다.At this time, even if the insulator 210 is broken by an external force, the first support body 410 and the second support body 430 of the insulator clamp 400 are connected to each other via the connecting rod 420 and the fixing nut 440. Since the insulation insulator 210 is wrapped and fixed, safety accidents can be delayed in that the separation of the insulator 210 and the resulting fall accident can be delayed as much as possible, and accordingly, the operator can take prompt follow-up measures. There is an advantage.
