Description

개폐가 용이한 맨홀뚜껑{Easily closed manhole cover}Easily closed manhole cover < RTI ID = 0.0 >

본 발명은 개폐가 용이한 맨홀뚜껑에 관한 것으로, 보다 상세하게는 지렛대의 원리를 이용하여 보다 적은 힘으로도 맨홀의 개폐가 가능하도록 개선한 맨홀뚜껑에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manhole cover which can be easily opened and closed, and more particularly, to a manhole cover improved to enable a manhole to be opened and closed even with less force using the principle of a lever.

주지하는 바와 같이 지하에 매설된 상수, 하수, 가스, 전기 및 통신 케이블 등 기반시설들의 유지관리 및 보수를 위하여 작업자가 드나들 수 있도록 맨홀을 설치하는데, 이러한 맨홀의 입구에는 안전과 위생 등의 이유로 원형 내지 사각형의 맨홀뚜껑을 병설하여 필요시에만 개폐하게 된다.As well known, manholes are installed for the maintenance and repair of infrastructures such as water, sewage, gas, electricity, and communication cables buried in the underground. For the safety and hygiene reasons, A round or square manhole cover is attached and opened only when necessary.

맨홀뚜껑은 주로 차도나 보도 등에 설치되기 때문에 외부 하중에 노출이 잦은 만큼 주철재나 콘크리트 등의 강성재료를 사용하는데, 통상 무게가 40kg 이상이며 틈새에 이물질이 끼거나 겨울에 습기가 동결되면 개폐가 더욱 힘들어진다.Since the manhole cover is mainly installed on a road or a sidewalk, it is often used as a steel material or a concrete material because it is frequently exposed to external load. Normally, when the weight of the manhole cover is 40kg or more, foreign matter is caught in the gap, It becomes more difficult.

종래의 맨홀뚜껑은 개폐용 홈에 쇠지레 등의 연장을 삽입하여 들어내는 방식을 흔히 사용하는데, 보통 2명의 작업자가 양쪽에서 도구를 사용하여 장시간 작업하므로 인력이 낭비될 뿐 아니라 전체 작업시간이 지체되고 작업의 효율이 저하되는 문제점이 있었다.Conventional manhole covers are often used by inserting an extension such as a crowbar into a groove for opening and closing. Usually, two workers use tools on both sides for a long time, which causes waste of manpower, There has been a problem that the efficiency of the work is deteriorated.

한국 공개특허 제20-0361658호(밀폐, 개폐 및 제조가 용이한 맨홀뚜껑)Korean Patent Laid-Open No. 20-0361658 (a manhole cover which is hermetically sealed, opened and closed and easy to manufacture)

본 발명은 상기한 종래의 문제점을 해결하기 위해 안출된 것으로서, 맨홀뚜껑을 개폐함에 있어서 보다 쉽고 편리한 수단을 제공하는 것을 목적으로 한다.SUMMARY OF THE INVENTION It is an object of the present invention to provide a more convenient and convenient means for opening and closing a manhole cover.

좀더 구체적으로는 더 적은 힘으로도 맨홀뚜껑을 들어올릴 수 있게 개선하여 작업자의 수고를 덜고 혼자서도 개폐작업을 수행할 수 있도록 함으로써 작업시간의 낭비를 막고 업무의 효율성을 향상하는데 목적이 있다.More specifically, it is possible to lift the manhole cover with less force, thereby reducing the labor of the worker and performing the opening / closing work alone, thereby preventing waste of work time and improving work efficiency.

상기와 같은 기술적 과제를 달성하기 위하여 본 발명은 맨홀 입구에 설치되어 맨홀뚜껑(2)을 수용하기 위한 구멍을 갖고 구멍의 아래쪽에 단이 형성된 맨홀뚜껑 지지구(1)와 상기 맨홀뚜껑 지지구(1)에 수용되고 맨홀뚜껑 거치면(1-1)에 얹혀져 맨홀 입구를 막는 맨홀뚜껑(2)과 상기 맨홀뚜껑(2)의 측면에 하나 이상 형성된 홈을 가로지르는 원통형의 힌지축(3)과 상기 힌지축(3)이 끼워지는 구멍을 갖고 구멍의 지름방향으로 양측단에 한쌍의 회전날개가 형성된 힌지(4)로 이루어진다.According to an aspect of the present invention, there is provided a manhole cover including a manhole cover provided with a hole for receiving the manhole cover and an end of the hole formed at the bottom of the manhole cover, 1, a manhole cover 2 which is placed on the manhole cover mounting surface 1-1 to block the manhole entrance, a cylindrical hinge shaft 3 which crosses a groove formed on one side of the manhole cover 2, And a hinge 4 having a hole through which the hinge shaft 3 is inserted and having a pair of rotary blades at both side ends thereof in the radial direction of the hole.

이와 같이 개폐용 홈에 힌지를 장착하는 단순한 구조개선으로 지렛대의 원리를 이용함으로써 더 적은 힘으로 맨홀뚜껑의 개폐가 가능하게 되는 것이다.In this way, by merely improving the structure of mounting the hinge in the opening-closing groove, the manhole cover can be opened and closed with less force by utilizing the principle of the lever.

본 발명은 지렛대의 원리를 이용하여 더 적은 힘으로도 맨홀뚜껑을 들어올릴 수 있기 때문에 맨홀뚜껑의 개폐작업시 작업자의 수고를 덜고 혼자서도 작업을 수행할 수 있게 되므로 작업시간의 지연을 방지하고 효율성이 향상되는 효과가 있다.Since the manhole cover can be lifted even with less force by using the principle of leverage, it is possible to reduce the labor of the operator in opening and closing the manhole cover and to perform the work alone, There is an effect to be improved.

이하, 본 발명의 개폐가 용이한 맨홀뚜껑을 구현하기 위한 바람직한 구성 실시예를 첨부된 도면에 의거하여 상세히 살펴보면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 맨홀 입구에 설치되어 맨홀뚜껑(2)을 수용하기 위해 중심을 관통하는 구멍을 갖고 구멍의 아래쪽에 단이 형성된 맨홀뚜껑 지지구(1)와; 상기 맨홀뚜껑 지지구(1)에 형성된 단의 윗면이면서 맨홀뚜껑(2)을 닫았을 때 맨홀뚜껑(2)의 아래면과 맞닿는 맨홀뚜껑 거치면(1-1)과; 상기 맨홀뚜껑 지지구(1)에 수용되고 맨홀뚜껑 거치면(1-1)에 얹혀져 맨홀 입구를 막는 맨홀뚜껑(2)과; 상기 맨홀뚜껑(2)의 측면에 하나 이상 형성된 홈을 가로지르는 원통형의 힌지축(3)과; 중심에 상기 힌지축(3)과 같은 지름으로 관통되어 힌지축(3)이 끼워지는 구멍을 갖고 구멍의 지름방향으로 양측단에 한쌍의 회전날개가 형성된 힌지(4)와; 상기 힌지(4)의 날개 중 쇠지레 등의 연장이 걸리도록 구부러진 형상을 갖는 연장 걸림부(4-1)와; 상기 힌지(4)의 날개 중 맨홀뚜껑(2)을 닫았을 때 상기 맨홀뚜껑 거치면(1-1)과 마주보게 되는 평평한 면인 힌지 바닥부(4-2)와; 상기 맨홀뚜껑(2)의 외주연과 같은 곡률을 갖고 맨홀뚜껑(2)을 닫았을 때 상기 맨홀뚜껑 지지구(1)의 내측면과 맞닿게 형성되는 힌지 후면(4-3)으로 이루어진다.The present invention relates to a manhole cover (1) provided at a manhole entrance and having a hole penetrating the center for receiving the manhole cover (2) and having an end at the lower end of the hole; A manhole cover mounting surface 1-1 which is an upper surface of an end of the manhole cover 1 and abuts against a lower surface of the manhole cover 2 when the manhole cover 2 is closed; A manhole cover 2 housed in the manhole cover 1 and resting on the manhole cover mounting surface 1-1 to block a manhole entrance; A cylindrical hinge shaft 3 crossing a groove formed at least one side of the manhole cover 2; A hinge (4) having a hole at the center thereof, the hinge shaft (3) having a diameter the same as the diameter of the hinge shaft (3) and having a pair of rotary blades at both side ends thereof in the radial direction of the hole; An extending hook portion 4-1 having a bent shape so as to be extended from the wing of the hinge 4; A hinge bottom 4-2, which is a flat surface facing the manhole cover mounting surface 1-1 when the manhole cover 2 is closed from the wings of the hinge 4; And a hinge rear surface (4-3) having a curvature equal to the outer circumference of the manhole cover (2) and formed to abut the inner surface of the manhole cover (1) when the manhole cover (2) is closed.

상기와 같이 구성된 본 발명의 작용에 대하여 살펴보면 다음과 같다.Hereinafter, the operation of the present invention will be described.

맨홀 설치시 입구에 맨홀뚜껑 지지구(1)가 구비되고 상기 맨홀뚜껑 지지구(1)에 형성된 맨홀뚜껑 거치면(1-1) 상에 맨홀뚜껑(2)을 얹음으로써 닫힌 상태를 유지한다.A manhole cover 1 is provided at the entrance of the manhole and a closed state is maintained by placing the manhole cover 2 on the manhole cover mounting surface 1-1 formed in the manhole cover 1. [

필요시 맨홀뚜껑(2)을 열 때는 쇠지레와 같은 긴 형상의 연장 끝부분을 맨홀뚜껑(2)과 연장 걸림부(4-1) 사이의 공간에 넣고 연장 걸림부(4-1)를 위쪽으로 당겨 연장 걸림부(4-1)가 수직으로 세워지게 한다.When the manhole cover 2 is opened when necessary, a long elongated end portion such as a crowbar is inserted into a space between the manhole cover 2 and the extending portion 4-1, and the extending portion 4-1 is moved upward So that the extension latching portion 4-1 is vertically erected.

이렇게 연장 걸림부(4-1)를 위쪽으로 당기면 반대쪽 날개의 힌지 바닥부(4-2)가 맨홀뚜껑 거치면(1-1)을 미는 힘의 반작용으로 맨홀뚜껑(2)이 기울면서 들어올려지고 힌지(4)가 완전히 수직으로 세워졌을 때는 힌지 후면(4-3)이 맨홀뚜껑 거치면(1-1)과 맞닿게 된다.When the extension latching part 4-1 is pulled upwards, the hinge bottom part 4-2 of the opposite wing is lifted by inclining the manhole cover 2 by the reaction force of pushing the manhole cover mounting surface 1-1 When the hinge 4 is completely vertically erected, the hinge rear surface 4-3 comes into contact with the manhole cover mounting surface 1-1.

이 과정에서 지렛대의 원리에 의해 힌지축(3)을 중심으로 적은 힘으로도 맨홀뚜껑(2)을 필요한 만큼 들어올릴 수 있기 때문에 작업자 혼자서도 개폐작업이 가능하게 된다.In this process, the manhole cover 2 can be lifted as much as necessary around the hinge shaft 3 by the principle of the leverage, so that the worker can open / close the work alone.

또한, 맨홀뚜껑(2)이 닫힌 상태에서는 도구를 사용하여 연장 걸림부(4-1)를 위쪽으로 당기지 않는 한 힌지(4)가 움직이지 않고, 만일 외부 힘에 의해 힌지(4)가 눌리더라도 힌지 후면(4-3)이 맨홀뚜껑 지지구(1)와 맞닿아 있으므로 힌지(4) 또는 맨홀뚜껑(2)이 움직이거나 돌출되어 안전사고가 발생할 수 있는 위험을 구조적으로 예방할 수 있다.In the state where the manhole cover 2 is closed, the hinge 4 does not move unless the extension latch portion 4-1 is pulled upward by using the tool, and if the hinge 4 is pushed by the external force, The risk that the hinge 4 or the manhole cover 2 moves or protrudes and a safety accident occurs can be structurally prevented because the rear surface 4-3 of the hinge 4 abuts against the manhole cover 1.
