본 발명은 지중배전용 케이블 완충장치에 관한 것으로, 더욱 상세하게는 지중에 설치되어 있는 전력케이블을 외부로부터 작용되는 진동으로부터 보호할 수 있는 지중배전용 케이블 완충장치에 관한 것이다. The present invention relates to a cable shock absorber for underground distribution, and more particularly, to a cable shock absorber for underground distribution that can protect a power cable installed in the ground from vibrations applied from the outside.

지중선로는 도시미관확보와 가공선로 시설이 기술적으로 불가능하고, 유지보수가 곤란한 지역에 주로 설치되며, 특히, 가공선이 집중되어 있는 변전소 인출 부근, 부하밀도가 높고 고층빌딩으로서 공급여력을 확보하는데 다회선 구성이 기술적으로 곤란한 개소 등에 설치된다.Underground lines are mainly installed in areas where technological aesthetics and overhead line facilities are technically impossible and difficult to maintain. Especially, near underground substations where concentrated overhead lines are concentrated. It is installed in a place where a line configuration is technically difficult.

이와 같은 지중선로에 이용되는 종래 케이블 지지구조는 첨부도면 도 1 및 도 2에 도시된 바와 같이 전력구 벽면(10)에 수직으로 설치되는 앵글(11)에 파이형장공(12)이 상하방향으로 일정한 간격을 이루도록 형성되어 있었고, 그 파이형장공(12)에 끼워져 걸리는 “T”자 모양의 걸림핀(13)이 수평바(14)의 측면에 경사지게 형성되어 있었으며, 수평바(14)의 하단 중앙에는 직각걸림편(15)이 형성되어 수평바(14)를 상측으로 기울인 상태에서 걸림핀(13)을 수직장공(12)에 끼운 다음 수평바(14)를 수평하게 내리게 되면, 걸림핀(13)이 수직장공(12)에 걸리는 동시에 수평바(14)에 형성된 걸림턱(15)이 앵글(11)의 수직단부에 걸리도록 구성되어 있었다.The conventional cable support structure used in such underground lines has a piezo-hole 12 in an up-down direction at an angle 11 installed perpendicularly to the power outlet wall surface 10 as shown in FIGS. 1 and 2. It was formed to form a constant interval, and the "T" shaped locking pin 13 to be fitted to the pie-shaped hole 12 was formed to be inclined to the side of the horizontal bar 14, the lower end of the horizontal bar 14 In the center, a right angle catching piece 15 is formed, and when the horizontal bar 14 is tilted upward, the locking pin 13 is inserted into the vertical slot 12, and then the horizontal bar 14 is lowered horizontally. 13 is caught by the vertical hole 12, and the locking step 15 formed in the horizontal bar 14 is configured to be caught by the vertical end of the angle (11).

The locking grooves 57 and 58 are formed.

그리고, 키홈(43)(44)을 갖는 핀구멍(45)을 수평바(40)의 측면에 형성하며, 핀구멍(45)으로 삽입되는 힌지핀(53)을 수직판(52)의 측면에 편중되게 형성하고, 키홈(43)(44)으로 삽입되어 걸리는 걸림돌기(54)(55)를 힌지핀(53)의 단부에 형성한다.A pin hole 45 having key grooves 43 and 44 is formed on the side of the horizontal bar 40, and the hinge pin 53 inserted into the pin hole 45 is formed on the side of the vertical plate 52. It is formed to be biased, and engaging projections 54 and 55 that are inserted into the key grooves 43 and 44 are formed at the ends of the hinge pins 53.

또, “U”자형으로 절곡된 판스프링(60)의 일측단부를 수직판(52)에 형성된 사각구멍(56)으로 삽입하여 고정하고, 수평바(40)의 상단에 형성된 브이홈(46)에 걸려서 지지되는 가동핀(61)을 판스프링(60)의 자유단(62)에 결합하며, 브이홈(46)의 모서리부분에 걸리는 원형헤드부(63)를 가동핀(61)의 단부에 형성한다.In addition, the one end of the leaf spring (60) bent in a "U" shape is inserted and fixed to the square hole 56 formed in the vertical plate 52, the v-groove 46 formed on the upper end of the horizontal bar (40) Coupled to the free end 62 of the leaf spring 60, the movable pin 61 is supported by the hook, and the circular head portion 63 is caught in the corner portion of the v-groove 46 to the end of the movable pin 61 Form.

Take it.

이하 본 발명에 따른 작용을 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the operation according to the present invention will be described in detail with reference to the accompanying drawings.

첨부도면 도 3 내지 도 5에 도시된 바와 같이 지하전력구 벽면(20)에 앵글(30)을 설치하기 위해 해머기능을 갖는 전동드릴을 이용하여 앵글(30)에 형성되어 있는 장공(32)의 중심과 동일한 구멍을 벽면(20)에 천공한 다음 그 구멍에 앵커볼트(33)을 박아 넣고, 앵글(30)에 형성되어 있는 장공(32)과 앵커볼트(33)의 중심을 서로 일치시킨 상태에서 앵글(30)을 벽면(20)에 밀착시키게 되면, 앵커볼트(33)가 장공(32)을 통해 돌출되는데 이때 돌출된 앵커볼트(33)에 앵커너트(34)를 결합하여 조이게 되면, 앵글(30)이 벽면(20)에 수직으로 고정된다.3 to 5 of the long hole 32 formed in the angle 30 by using an electric drill having a hammer function to install the angle 30 on the underground power outlet wall surface 20 as shown in FIG. A hole identical to the center is drilled in the wall surface 20, and then anchor bolt 33 is inserted into the hole, and the center of the long hole 32 formed in the angle 30 and the anchor bolt 33 coincide with each other. When the angle 30 is in close contact with the wall surface 20, the anchor bolt 33 is protruded through the long hole 32, when the anchor bolt 34 is coupled to the protruding anchor bolt 33 and tightened, the angle 30 is fixed perpendicular to the wall surface 20.

이후 반원파이프(50)의 아래쪽에 형성되어 있는 수직판(52)에 판스프링(60)을 결합하기 위해 판스프링(60)의 고정단(64)을 수직판(52)에 형성되어 있는 사각구멍(56)으로 삽입하게 되면, 고정단(64)에 형성되어 있는 절곡부(65)가 반대편으로 돌출된다.After that, in order to couple the leaf spring 60 to the vertical plate 52 formed at the bottom of the semi-circular pipe 50, the fixed end 64 of the leaf spring 60 is formed in the vertical plate 52 When inserted into the 56, the bent portion 65 formed in the fixed end 64 protrudes to the opposite side.

이때 집게 등을 이용해서 절곡부(65)를 구부리게 되면, 절개부(66) 길이만큼 절곡부(65)가 절곡되면서 수직판(52)에 걸리게 되며, 결국 판스프링(60)의 고정단(64)이 수직판(52)에 견고하게 고정된다.At this time, when the bent portion 65 is bent by using a forceps, the bent portion 65 is bent by the length of the cut portion 66 and is caught on the vertical plate 52, and thus, the fixed end of the leaf spring 60 ( 64 is firmly fixed to the vertical plate 52.

이와 같이 판스프링(60)을 수직판(52)에 조립하는 작업은 현장에서 진행해도 되지만 편의를 위해 공장에서 제작한 후 현장으로 이동하여 사용하면 보다 편리하게 이용할 수 있다.Thus, the work of assembling the leaf spring 60 to the vertical plate 52 may be carried out in the field, but for convenience, it is more convenient to use after moving to the field after manufacturing in the factory.

그리고, 수평바(40)를 앵글(30)에 결합한 다음 반원파이프(50)를 수평바(40)에 조립하기 위해 수직판(52)의 측면으로부터 돌출형성되어 있는 힌지핀(53)의 중심과 수평바(40)에 형성되어 있는 핀구멍(45)의 중심을 일치시킨 다음 힌지핀(53)에 형성되어 있는 걸림돌기(54)(55)와 키홈(43)(44)이 일치되도록 반원파이프(50)와 수직판(52)을 기울인 상태에서 힌지핀(53)을 핀구멍(45)으로 삽입하게 되면, 걸림돌기(54)(55)가 키홈(43)(44)을 통해 삽입된다.Then, the center of the hinge pin (53) protruding from the side of the vertical plate (52) to couple the horizontal bar (40) to the angle (30) and then to assemble the semicircular pipe (50) to the horizontal bar (40). After matching the center of the pin hole 45 formed in the horizontal bar 40, the semicircular pipe so that the engaging projections 54, 55 and the key grooves 43, 44 formed in the hinge pin 53 is matched. When the hinge pin 53 is inserted into the pin hole 45 while the 50 and the vertical plate 52 are inclined, the locking protrusions 54 and 55 are inserted through the key grooves 43 and 44.

이때 반원파이프(50)와 수직판(52)을 수평하게 돌리게 되면, 힌지핀(53)에 형성되어 있는 걸림돌기(54)(55)가 핀구멍(45)의 모서리 부분에 걸리면서 결합되며, 수직판(52)에 결합되어 있는 판스프링(60)의 자유단(62)에 설치되어 있는 가동핀(61)은 수평바(40)의 상단에 형성되어 있는 브이홈(46)에 걸리게 된다.At this time, when the semi-circular pipe 50 and the vertical plate 52 is turned horizontally, the engaging projections 54 and 55 formed in the hinge pins 53 are engaged while being caught in the corner portions of the pin holes 45, The movable pin 61 provided at the free end 62 of the leaf spring 60 coupled to the direct plate 52 is caught by the v-groove 46 formed at the upper end of the horizontal bar 40.

또, 가동핀(61)의 단부에 형성되어 있는 원형헤드부(63)가 브이홈(46)의 모서리부분에 걸리면서 수직판(52)의 측방향 이탈을 방지하는데 도움을 주게 된다.In addition, the circular head portion 63 formed at the end of the movable pin 61 is caught by the corner portion of the v-groove 46 to help prevent the lateral separation of the vertical plate (52).

위와 같은 상태에서 반원파이프(50)의 케이블안착면(51)에 전력케이블(22)을 올려놓고 타이밴드, 결속와이어 등과 같은 밴드결속수단을 이용해서 전력케이블(22)과 반원파이프(50)를 감아서 결합하게 되면, 전력케이블(22)이 반원파이프(50)에 고정된다. In the above state, the power cable 22 is placed on the cable seating surface 51 of the semicircular pipe 50, and the power cable 22 and the semicircular pipe 50 are connected using a band binding means such as a tie band or a binding wire. When combined by winding, the power cable 22 is fixed to the semicircular pipe (50).

이때 밴드결속수단이 반원파이프(50)의 외주면에 형성되어 있는 밴드걸림홈(57)(58)에 위치되도록 하면 밴드결속수단의 이탈을 방지할 수 있게 된다.At this time, if the band binding means is located in the band engaging grooves 57 and 58 formed on the outer circumferential surface of the semicircular pipe 50, the band binding means can be prevented from being separated.

한편, 지상이나 지하로부터 전달되는 진동이 벽면(20)과 앵글(30)을 통해 수평바(40)로 전달되거나 그 반대로 전력케이블(22)로부터 전달된 진동이 수평바(40)를 통해 앵글(30)로 전달되는 경우 반원파이프(50)와 일체로 되어 있는 수직판(52)이 힌지핀(53)에 의해 지지되어 있고, 수직판(52)에 고정되어 있는 판스프링(60)에 설치된 가동핀(61)이 수평바(40)의 상단에 형성되어 있는 브이홈(46)에 지지되어 있으므로, 외력이 작용되는 경우 수직판(52)은 힌지핀(53)을 중심으로 회동되면서 동시에 판스프링(60)이 탄성변형을 일으켜 진동을 흡수하게 된다.On the other hand, the vibration transmitted from the ground or underground is transmitted to the horizontal bar 40 through the wall surface 20 and the angle 30, or vice versa, the vibration transmitted from the power cable 22 is transmitted through the horizontal bar 40 30, the vertical plate 52, which is integral with the semicircular pipe 50, is supported by the hinge pin 53 and is installed on the plate spring 60 fixed to the vertical plate 52. Since the pin 61 is supported by the V-groove 46 formed at the upper end of the horizontal bar 40, when the external force is applied, the vertical plate 52 is rotated about the hinge pin 53 and at the same time the leaf spring. 60 causes elastic deformation to absorb vibration.

즉, 판스프링(60)의 자유단(62)에 설치되어 있는 가동핀(61)은 브이홈(46)으로부터 미끄러지면서 판스프링(60)의 탄성변형을 돕게 되며, 동시에 수직판(52)을 지지하는 역할도 하게 된다.That is, the movable pin 61 installed at the free end 62 of the leaf spring 60 helps the elastic deformation of the leaf spring 60 while sliding from the v-groove 46, and at the same time the vertical plate 52 It also serves as a supporter.
