Description

공동주택용 지중선로 케이블 지지장치{Underground power lines support apparatus for apartment house}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an underground power line support apparatus for an apartment house,

본 발명은 공동주택용 지중선로 케이블 지지장치에 관한 것으로, 더욱 상세하게는 지중전력구 곡선구간에 설치되는 지중케이블을 곡선구간의 곡률반경에 맞게 조절하여 설치할 수 있고, 지중전력구의 직선구간에도 적용할 수 있는 공동주택용 지중선로 케이블 지지장치에 관한 것이다.The present invention relates to an underground cable support device for a residential area, and more particularly, to a cable support device for a subway underground cable which can be installed by adjusting an underground cable installed in a subway underground power curve to a radius of curvature of a curve section, To an underground cable support device for a residential house.

지중선로는 도시미관 확보와 가공선로 시설이 기술적으로 불가능하고, 유지보수가 곤란한 지역에 주로 설치되며, 가공선이 집중되어 있는 변전소 인출 부근, 부하밀도가 높고 고층빌딩으로서 공급여력을 확보하는데 다회선 구성이 기술적으로 곤란한 개소 등에 설치된다.The underground line is mainly installed in the area where maintenance of the city is difficult and the maintenance of the city is not technically possible due to the securing of aesthetics of the city and the substation where the service lines are concentrated. The load density is high and the supply capacity is secured as high-rise buildings. Is installed in a technically difficult position or the like.

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 수직장공(12)이 상하방향으로 일정한 간격을 이루도록 형성되어 있고, 그 수직장공(12)에 끼워져 걸리는 "T"자 모양의 걸림쇠(13)가 케이블지지대(14)의 측면에 형성되어 있으며, 케이블지지대(14)의 하단 중앙에는 직각으로 절곡된 걸림턱(15)이 형성되어 케이블지지대(14)를 상측으로 기울인 상태에서 걸림쇠(13)를 수직장공(12)에 끼운 다음 케이블지지대(14)를 수평하게 내리게 되면, 걸림쇠(13)가 수직장공(12)에 걸리는 동시에 케이블지지대(14)에 형성된 걸림턱(15)이 앵글(11)의 단부에 걸리도록 되어 있었다.The conventional cable support structure used for such an underground cable has a structure in which a vertical slot 12 is formed in an angle 11 vertically installed on a power hole wall 10 as shown in FIGS. 1 and 2, Quot; T "-shaped latch 13, which is inserted into the vertical slot 12, is formed on the side of the cable support 14, and the lower end of the cable support 14 is formed at a right angle When the cable support 14 is lowered horizontally after the bent portion 15 is formed and the cable support 14 is tilted upward and the cable 13 is inserted into the vertical slot 12, The engagement protrusion 15 formed on the cable support 14 is caught by the end of the angle 11 while being caught by the vertical slot 12.

또, 케이블지지대(14)에 형성된 걸림쇠(13)는 측방향으로 이탈되는 것을 방지하는 작용을 하고, 걸림턱(15)은 케이블지지대(14)가 수평을 유지하도록 하는 작용을 하게 된다.In addition, the latch 13 formed on the cable support 14 acts to prevent lateral deviation, and the latching jaw 15 acts to keep the cable support 14 horizontal.

그러나, 이와 같은 종래 지중선로용 케이블 지지구조는 지중전력구의 곡선구간에 맞게 지중케이블의 곡률반경을 조절할 수 없기 때문에 지중케이블이 지중전력구의 벽면과 균일한 간격을 이루지 못하여 지중전력구의 곡선구간 통행로가 좁아지거나 불규칙하게 되는 문제점이 있었다.However, since the conventional cable supporting structure for the underground cable can not control the radius of curvature of the underground cable in accordance with the curve section of the underground power cable, the underground cable can not be uniformly spaced from the wall surface of the underground power cable, There is a problem in that it becomes narrow or irregular.

이러한 본 발명의 목적을 달성하기 위하여 전력케이블의 곡률반경에 맞게 휘어지는 플렉시블한 "T"자 모양의 고무스페이서를 중앙지지대의 상면에 설치된 고무판 위에 일정 간격을 이루도록 수직으로 세워서 설치하고, 고정홈이 등각도로 형성된 고정링을 보강리브를 통해 중앙지지대의 후부에 설치하며, 회전홈이 등각도로 형성된 회전링을 고정링 위에 중심이 일치되도록 상하방향으로 적층하여 설치하고, 중앙지지대의 좌우측에 위치되는 각도조절지지대를 연결암을 통해 회전링에 설치하며, 고정홈과 회전홈에 삽입되어 맞물리는 결합리브가 외주면에 형성된 중공축을 회전링과 고정링에 삽입 설치하고, 중공축의 중심에 형성된 중공홀로 삽입된 고정볼트 단부에 너트를 결합하여 공동주택용 지중선로 케이블 지지장치가 제공된다.In order to achieve the object of the present invention, a flexible "T" -shaped rubber spacer bent according to the radius of curvature of the power cable is installed vertically upright on the rubber plate provided on the upper surface of the center support, A rotary ring formed by turning is formed on the rear side of the central support through a reinforcing rib and the rotating ring formed with an equal angle of rotation is stacked in the vertical direction so that its center is on the fixed ring, A support shaft is installed in the rotary ring through a connection arm. A hollow shaft having an engaging rib inserted and engaged with the rotary groove is inserted into the rotary ring and the fixed ring. The fixed bolt inserted into the hollow hole formed at the center of the hollow shaft A cable support device is provided with an underground line for a residential house by combining the nut at the end.

이상에서 설명한 바와 같은 본 발명은 회전링과 고정링 및 중공축에 의해 지중케이블의 곡률반경을 지중전력구의 곡선구간 벽면의 곡률반경에 맞게 조절할 수 있도록 구성되어 있기 때문에 지중케이블과 지중전력구의 벽면과의 거리를 일정한 거리로 유지할 수 있게 되어 지중전력구의 통행로를 일정한 폭으로 유지할 수 있으므로, 점검자의 통행을 자유롭게 하여 유지보수 및 점검을 편리하게 할 수 있는 효과가 있다.As described above, according to the present invention, since the radius of curvature of the underground cable can be adjusted to the radius of curvature of the underground power wall by the rotating ring, the stationary ring and the hollow shaft, It is possible to keep the distance of the underground electric power section at a constant distance, so that the passage of the underground electric power section can be maintained at a constant width, so that the passage of the inspector can be freely made and the maintenance and inspection can be made convenient.

또한, 중앙지지대 위의 고무판에 형성된 고무스페이서에 의해 전력케이블의 곡선부위 간격을 일정하게 유지하면서 동시에 전력케이블을 구부릴 때 플렉시블 한 고무스페이서도 함께 휘도록 되어 있으므로, 곡률조절작업이 편리하게 될 뿐만 아니라 휘어진 고무스페이서에 의해 전력케이블의 절연피복부 손상을 줄일 수 있는 효과도 있다.In addition, since the rubber spacers formed on the rubber plate on the central support stand keep the distance between the curved portions of the power cable constant and bend the flexible cable when bending the power cable, the curvature adjustment operation is convenient There is also an effect of reducing the insulation damages of the power cable by the bent rubber spacer.
