The present invention relates to a power cable curve support device for underground distribution, and more particularly, a load concentrated on a local part by adjusting a cleat for supporting a power cable bent in a curved shape due to deflection to a curvature radius such as a power cable. The present invention relates to a power cable curve support device for underground distribution, which can protect the insulation coating of the power cable by evenly distributing.

일반적으로 송배전 케이블은 지상에 설치되는 가공선과 지하에 설치되는 지중선으로 대별된다. 이중 지중선은 지중의 전력구에 설치하여 도시미관을 깔끔하게 할 수 있고 점검이 용이하게 되는 장점이 있다.In general, transmission and distribution cables are roughly divided into overhead lines installed underground and underground cables installed underground. The double underground line has the advantage that can be installed in the underground power port to clean the city view and easy to check.

이러한 전력구에는 중앙에 작업자가 통행할 수 있는 통로가 마련되어 있으며, 전력구 벽면에 설치된 앵글에 수평하게 설치된 행거 위에 전력케이블들이 걸쳐지는 형태로 배치된다.The power port is provided with a passage for the operator to pass in the center, and arranged in such a way that the power cables are placed on a hanger horizontally installed at an angle installed on the wall of the power port.

종래 지중배전용 케이블 지지장치는 첨부도면 도1에 도시된 바와 같이 전력구 벽면에 수직으로 설치된 앵글(10)에 행거(11)가 수평하게 설치되어 있었으며, 그 행거(11)에는 전력케이블(12)을 지지하기 위한 반원형의 케이블안착홈(13)이 형성된 클리트(14)가 설치되어 있었고, 클리트(14)에 형성된 케이블안착홈(13)에 전력케이블(12)이 걸쳐진 형태로 설치되어 있었다.In the conventional underground cable support apparatus for the underground distribution, as shown in FIG. 1, a hanger 11 is horizontally installed at an angle 10 vertically installed on a wall of a power outlet, and the power cable 12 is mounted on the hanger 11. The cleat 14 in which the semicircular cable seating groove 13 for supporting) was provided, and the power cable 12 was installed in the cable seating groove 13 formed in the cleat 14.

그런데, 클리트(14)에 걸치는 전력케이블(12)은 플렉시블하게 만들어져 있기 때문에 일직선을 이루지 못하고 클리트(14)와 멀어질수록 밑으로 처지면서 정현파모양으로 휘게 된다.However, since the power cable 12 that extends over the cleats 14 is made flexible, the power cables 12 do not form a straight line and are bent in a sinusoidal wave shape as they move away from the cleats 14.

따라서 종래 클리트(14)에 지지된 전력케이블(12)은 도1에 도시된 바와 같이 클리트(14)의 중앙부에서는 들뜨는 현상이 나타나게 되고, 클리트(14)의 모서리부(14a)(14b)에서는 선접촉 형태로 하중이 집중되기 때문에 전력케이블(12)의 국부에 하중이 집중되면서 절연피복부가 쉽게 손상되는 문제점이 있었다.Therefore, as shown in FIG. 1, the power cable 12 supported by the conventional cleats 14 appears to be lifted at the center of the cleats 14, and the edges 14a and 14b of the cleats 14 are wired. Since the load is concentrated in the contact form, the load is concentrated on the local portion of the power cable 12, so that the insulation coating is easily damaged.

본 발명은 상기와 같은 문제점을 해결하기 위하여 이루어진 것으로, 그 목적은 곡선형으로 처진 전력케이블의 곡률반경에 일치되게 클리트의 곡률반경을 가변시킬 수 있도록 함으로써 전력케이블의 절연피복부를 보호할 수 있는 지중배전용 전력케이블 곡선지지장치를 제공함에 있다.The present invention has been made to solve the above problems, the object of which is to make the curvature radius of the cleats to match the curvature radius of the sagging power cable in a curve that can protect the insulation coating of the power cable underground The present invention provides a curved support device for power distribution.

이러한 본 발명의 목적을 달성하기 위하여 완만한 곡면으로 형성된 고무클리트에 형성된 케이블안착부를 가로지르는 방향으로 복수의 절개홈을 형성하고, 상면에 고무클리트가 올려지는 판스프링의 양단에 원형으로 말린 경첩부를 형성하며, 판스프링에 형성된 체결공에 삽입되는 버섯머리모양의 체결보스를 고무클리트의 저면에 형성하고, 경첩부에 삽입되는 슬리브의 중공홀에 고정핀과 슬라이드핀을 삽입하며, 고정바를 안내하기 위한 “C”형 단면의 직선안내부를 슬라이드바의 일측단부에 형성하고, 고정바와 슬라이드바의 타측단부에 각각 형성된 핀구멍에 고정핀과 슬라이드핀의 양단을 결합하며, 슬라이드바에 형성된 볼트걸림부를 관통하는 길이조정볼트를 고정바의 일측단부에 형성된 너트부에 결합하고, 크로스바에 의해 간격을 이루면서 결합되고 행거에 의해 지지되는 하부프레임의 양측단부에 고정핀과 슬라이드핀 지지를 위한 힌지구멍과 가이드장공을 형성하여 지중배전용 전력케이블 곡선지지장치가 제공된다.In order to achieve the object of the present invention, a plurality of cutting grooves are formed in a direction crossing the cable seating portion formed in the rubber cleat formed with a smooth curved surface, and the hinge portion is circularly wound at both ends of the leaf spring on which the rubber cleat is raised. And forming a mushroom head-shaped fastening boss inserted into the fastening hole formed in the leaf spring on the bottom of the rubber cleat, inserting the fixing pin and the slide pin into the hollow hole of the sleeve inserted into the hinge portion, and guiding the fixing bar. A straight guide portion having a “C” -shaped cross section is formed at one end of the slide bar, and both ends of the fixing pin and the slide pin are coupled to pin holes respectively formed at the fixed bar and the other end of the slide bar, and penetrate the bolt catching portion formed in the slide bar. The length adjusting bolt to the nut part formed at one end of the fixing bar, And a hinge hole and a guide hole for supporting the fixing pin and the slide pin at both ends of the lower frame, which are coupled and supported by the hanger, provide a power cable curve support device for underground distribution.

이상에서 설명한 바와 같은 본 발명은 처진 전력케이블의 곡률반경에 맞게 고무클리트의 곡률반경을 조정할 수 있으므로, 전력케이블의 절연피복부와 고무클리트의 케이블안착부가 면접촉되어 하중이 고르게 분포되기 때문에 전력케이블의 절연피복부를 보호할 수 있게 되는 효과가 있다.The present invention as described above can adjust the radius of curvature of the rubber cleat to the radius of curvature of the sagging power cable, so that the load is evenly distributed by the surface contact of the insulation coating of the power cable and the cable seat of the rubber cleat power cable It is effective to protect the insulation coating of the.

더 나아가서 본 발명은 전력케이블을 지지하기 위한 고무클리트의 곡률반경을 길이조정볼트와 판스프링 및 주변장치에 의해 가변시킬 수 있도록 구성되어 있기 때문에 전력케이블의 처짐량에 따라 고무클리트의 곡률반경을 임의로 설정할 수 있게 되는 효과가 있다.Furthermore, since the curvature radius of the rubber cleat for supporting the power cable is configured to be changed by the length adjusting bolt, the leaf spring and the peripheral device, the curvature radius of the rubber cleat can be arbitrarily set according to the deflection amount of the power cable. There is an effect that becomes possible.

또한, 본 발명은 고무클리트에 절개홈이 형성되어 있기 때문에 판스프링에 의해 고무클리트가 탄성변형될 때 고무클리트가 터지는 현상을 방지할 수 있을 뿐만 아니라 고무클리트에 의한 탄성저항이 줄어들기 때문에 길이조정볼트에 가하는 회전력을 보다 작게 할 수 있기 때문에 조작성이 향상되는 효과가 있다.In addition, the present invention not only prevents the rubber cleats from popping when the rubber cleats are elastically deformed by the leaf springs because the incision grooves are formed in the rubber cleats, and the length of the rubber cleats is reduced because the elastic resistance is reduced. Since the rotational force applied to the bolt can be made smaller, the operability is improved.

이때 하부프레임(90)(92)에 형성되어 있는 힌지구멍(93)(94)에 고정핀(60)을 통해 결합되어 있는 고정바(70)(72)는 행거(24) 위에서 정지된 상태이며, 하부프레임(90)(92)에 형성되어 있는 가이드장공(95)(96)에 미끄럼 결합되어 있는 슬라이드핀(62)에 결합되어 있는 슬라이드바(80)(82)는 행거(24) 위에서 움직임을 갖게 된다.In this case, the fixing bars 70 and 72 coupled to the hinge holes 93 and 94 formed in the lower frames 90 and 92 through the fixing pins 60 are stopped on the hanger 24. The slide bars 80 and 82 coupled to the slide pins 62 sliding to the guide slots 95 and 96 formed on the lower frames 90 and 92 move on the hangers 24. Will have

이때 고무클리트(30)에 형성되어 있는 절개홈(32)은 고무클리트(30)의 탄성변형시 터짐을 방지하는 작용을 하고, 고무클리트(30)에 의해 발생될 수 있는 탄성저항력을 줄여 주는 작용을 하여 길이조정볼트(74)(75)를 돌릴 때 좀 더 작은 힘으로 조정할 수 있도록 하게 된다.At this time, the cutting groove 32 formed in the rubber cleat 30 serves to prevent bursting when the rubber cleat 30 is elastically deformed, and reduces the elastic resistance that may be generated by the rubber cleat 30. When the length adjustment bolt (74) (75) is to be adjusted to a smaller force.

즉, 길이조정볼트(74)(75)를 느슨하게 풀면 판스프링(40)의 탄성복원력에 의해 판스프링(40)의 곡률반경이 커지면서 동시에 고무클리트(30)의 곡률반경도 커지게 되고, 길이조정볼트(74)(75)를 조이게 되면, 판스프링(40)의 곡률반경이 작아지면서 동시에 고무클리트(30)의 곡률반경도 작아지면서 전력케이블(220)의 처짐에 따른 곡률반경에 맞게 고무클리트(30)의 곡률반경을 임의로 조정할 수 있게 된다.That is, when the length adjustment bolts 74 and 75 are loosened, the radius of curvature of the leaf spring 40 is increased by the elastic restoring force of the leaf spring 40, and at the same time, the radius of curvature of the rubber cleat 30 is also increased. When the bolts 74 and 75 are tightened, the radius of curvature of the leaf spring 40 is reduced and at the same time the radius of curvature of the rubber cleat 30 is also reduced, so that the rubber cleats (according to the curvature radius according to the sag of the power cable 220) are reduced. The radius of curvature of 30) can be adjusted arbitrarily.

이와 같이 고무클리트(30)의 곡률반경이 처진 전력케이블(220)의 곡률반경에 맞게 조정되면, 고무클리트(30)의 케이블안착부(31)에 전력케이블(220)이 밀착되어 면접촉되기 때문에 전력케이블(220)과 고무클리트(30)에 작용되는 하중이 고르게 분포되어 전력케이블(220)의 절연피복부를 보호할 수 있게 된다.As such, when the radius of curvature of the rubber cleat 30 is adjusted to the radius of curvature of the sagging power cable 220, the power cable 220 is brought into close contact with the cable seating portion 31 of the rubber cleat 30. The load applied to the power cable 220 and the rubber cleat 30 is evenly distributed to protect the insulation coating of the power cable 220.
