Description

맨홀뚜껑 개폐장치Manhole Cover Switch

본 고안은 통신 맨홀뚜껑을 개폐하기 위한 장치에 관한 것으로, 특히 지렛대의 원리를 이용하여 작업자가 작은 힘으로 맨홀뚜껑을 용이하게 개폐할 수 있는 맨홀뚜껑 개폐장치에 관한 것이다.The present invention relates to a device for opening and closing a communication manhole cover, and more particularly, to a manhole cover opening and closing device that can be easily opened and closed the manhole cover with a small force by using the principle of the lever.

일반적으로, 도로 밑에 매설되어 있는 통신케이블의 유지보수 또는 점검작업시에 맨홀뚜껑을 열고 그 내부로 들어가서 보수, 점검을 하고 있다.In general, during the maintenance or inspection work of communication cables buried beneath the road, the manhole cover is opened and entered into it for maintenance and inspection.

여기서, 상기 맨홀뚜껑은 통상 주물로 제작되어 있기 때문에 무게가 상당히 무겁다. 따라서, 통신케리블 유지보수에 따른 맨홀뚜껑 개방시에는 곡괭이나 삽, 갈고리 등으로 맨홀뚜껑의 홀에 삽입한 후 들어 이탈시키는데, 이때 여럿의 작업자가 투입되어 맨홀을 이동시키고 있으며, 또한 작업완료 후에는 역순으로 여러 작업자가 들어 맨홀에 닫고 있는 실정이다.Here, since the manhole cover is usually made of castings, the weight is quite heavy. Therefore, when opening the manhole cover according to the maintenance of communication cable, it is inserted into the hole of the manhole cover with a pickaxe, shovel, hook, etc., and then lifted off. At this time, several workers are put in to move the manhole, and after the work is completed, Is the situation where several workers in the reverse order to close the manhole.

이에 따라, 맨홀의 개폐시에는 항상 여럿의 작업자가 대기하고 있어야 하므로 작업능률 저하 및 인력손실을 가져오며, 또한 맨홀뚜껑을 여러 작업자가 함께 힘을 쓰면서 개폐해야 하므로 이 과정에서 자칫 실수하여 안전사고가 발생하는 문제점을 내포하고 있었다.Accordingly, when opening and closing the manhole, several workers must be waiting at all times, resulting in deterioration of work efficiency and loss of manpower, and in addition, the manhole cover must be opened and closed while several workers work together. There was a problem that occurred.

따라서, 본 고안은 상기의 제반 문제점을 해결하기 위하여 안출된 것으로서, 도로상에 산재한 통신 맨홀뚜껑을 지렛대의 원리를 이용하여 작업자가 작은 힘으로 쉽고 안전하게 개폐할 수 있도록 하는 맨홀뚜껑 개폐장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, to provide a manhole cover opening and closing device that allows the operator to open and close easily and safely with a small force using the principle of the lever of the communication manhole cover scattered on the road. The purpose is.

본 고안에 의한 맨홀뚜껑 개폐장치는 자체하중이 무거운 맨홀뚜껑을 작업자가 작은 힘으로 쉽게 들어올려 개폐를 용이하게 할 수 있도록 구현한 것으로, 본 실시예에서는 지렛대의 원리를 이용하여 맨홀뚜껑을 개폐할 수 있도록 한 구조로 되어 있다. 제1도를 참조하여 좀더 상세히 설명하면, 그 일측단부에서 소정길이만큼 떨어진 지점에서 소정각도로 굴곡되어 힘의 수평이동을 가질 수 있도록 하며, 굴곡부(1a)를 이루는 상부측 직선부 상단에 손잡이(2)가 일체로 장착된 중공봉 향상의 중심지지바(1)가 구비된다.The manhole cover opening and closing device according to the present invention implements a manhole cover with a heavy load so that an operator can easily lift and close it with a small force. In this embodiment, the manhole cover can be opened and closed using the principle of a lever. It is structured so that. In more detail with reference to Figure 1, it is bent at a predetermined distance from the one end portion to be bent at a predetermined angle to have a horizontal movement of the force, the handle on the top of the upper straight portion forming the bent portion (1a) ( 2) is provided with a central support bar (1) of the hollow rod enhancement.

여기서, 상기 굴곡부(1a)는 작업자가 최소의 힘으로 끌어내릴 수 있도록 45°~ 65°정도로 구부러지도록 형성한다.Here, the bent portion (1a) is formed to be bent at about 45 ° ~ 65 ° so that the operator can be pulled down with a minimum force.

그리고, 상기 중심지지바(1)의 굴곡부(1a) 아랫측 직선부에는 맨홀뚜껑(11)을 들어 올릴 때 받침대기능을 하며, 또한 상기 중심지지바(1)에 이동력을 제공하는 바퀴축(4) 및 바퀴(3)가 설치된다. 이때, 상기 굴곡부(1a)와 바퀴축(4)은 서로 용접되어 고정된다.In addition, the wheel shaft 4 which functions as a pedestal when lifting the manhole cover 11 on the straight side of the lower portion of the bent portion 1a of the center support bar 1 and also provides a movement force to the center support bar 1. And wheels 3 are installed. At this time, the bent portion (1a) and the wheel shaft (4) is fixed to each other by welding.

본 실시예에서는 바퀴(3)에 베어링(5)을 내장하여 그의 구름을 원활히 하며, 상기 맨홀뚜껑(11) 견인시 힘의 모멘트가 수평으로 쉽게 이동되도록 한다.In this embodiment, the bearing (5) is built into the wheel (3) to smooth the rolling thereof, the force of the force when the manhole cover 11 is to be easily moved horizontally.

상기 중심지지바(1)의 굴곡부(1a) 단부 내측에는 소정길이만큼 암나사(1b)가 형성되어 있으며, 굴곡부(1a)의 둘레면에는 스토퍼(6)가 고정되어 있다. 또한, 상기 암나사(1b)에는 캡(7)이 체결되는데, 이때 상기 캡(7)의 둘레면에는 스토퍼 기능을 하는 이탈방지링(7a)가 일체로 구비되어 있다.A female screw 1b is formed inside the end of the bent portion 1a of the central support bar 1 by a predetermined length, and the stopper 6 is fixed to the circumferential surface of the bent portion 1a. In addition, the cap 7 is fastened to the female screw 1b, in which the release preventing ring 7a having a stopper function is integrally provided on the circumferential surface of the cap 7.

상기 캡(7)의 이탈방지링(7a)과 스토퍼(6) 사이의 중심지지바(1)에는 맨홀뚜껑(1)에 형성된 홈에 걸수 있도록 환형 고리(8)가 유동가능하게 끼워진다. 따라서, 상기 환형고리(8)를 맨홀뚜껑(11)의 홈에 걸고 바퀴(3)를 받침지지대로 하여 손잡이(2)를 누르게 되면, 지렛대의 원리에 의해 맨홀뚜껑(11)이 쉽게 들리게 된다.An annular ring 8 is fitted in the center support bar 1 between the release preventing ring 7a and the stopper 6 of the cap 7 so as to be hooked into a groove formed in the manhole cover 1. Therefore, when the hook 2 is pressed into the groove of the manhole cover 11 and the wheel 3 is supported as a support, the manhole cover 11 is easily lifted by the principle of the lever.

이때, 본 고안에서는 소정길이를 가지는 받침봉(9)을 적어도 하나 이상 구비하여 들려진 맨홀뚜껑(11) 사이에 끼워넣어 그를 이동시키는 롤러기능을 할 수 있도록 한다.At this time, the present invention is provided with at least one or more supporting rods 9 having a predetermined length to be sandwiched between the lifted manhole cover 11 to enable the roller function to move them.

또한, 상기 중심지지바(1)의 굴곡부(1a) 상측 직선부 소정위치에 지지돌기(10)를 구비하여 받침봉(9)에 형성된 홀(9a)이 끼워져 지지되도록 함으로써 휴대를 간편히 할 수 있도록 한 구조로 되어 있다.In addition, the support protrusion 10 is provided at a predetermined position on the upper straight portion of the bent portion 1a of the center support bar 1 so that the hole 9a formed in the support bar 9 is inserted and supported to facilitate carrying. It is structured.

상기와 같이 구성된 본 고안의 사용상태를 제4A도 내지 제4D도를 통하여 설명하면 다음과 같다.Referring to the use state of the present invention configured as described above with reference to FIGS. 4A to 4D.

도면에 도시한 바와 같이 맨홀뚜껑(11)을 열 경우에는 중심지지바(1)에 구비된 스토퍼(6)와 캡(7) 사이에 설치된 환형고리(8)를 맨홀뚜껑(11)의 홈에 끼우고 바퀴(3)를 받침대로 하여 손잡이(2)를 눌러 들어올린다.When opening the manhole cover 11 as shown in the drawing, the annular ring 8 provided between the stopper 6 and the cap 7 provided on the center support bar 1 is inserted into the groove of the manhole cover 11. Then press the handle (2) to lift the wheel (3) as a base.

그리고, 상기 받침봉(9)을 맨홀뚜껑(11)의 하부에 끼워넣고 밀거나 당긴다. 이에 따라, 상기 중심지지바(1)가 바퀴(3)의 구름동작에 의해 이동됨과 동시에, 상기 받침봉(9)이 구르면서 맨홀뚜껑(11)을 쉽게 외부로 이탈시키게 되는 것이다. 이와는 반대로, 상기 맨홀뚜껑(11)을 닫을 경우에는 받침봉(9)의 상부측에 놓인 맨홀뚜껑(11)에 환형고리(8)를 걸고 중심지지바(1)를 밀거나 당기면서 맨홀 위치로 위치시킨다. 그리고 상기, 맨홀뚜껑(11)의 일부가 맨홀에 삽입되면, 바퀴(3)를 받침대로 하여 중심지지바(1)를 눌러 맨홀뚜껑(11)을 들러올리고 받침봉(9)을 빼낸 다음 닫게 하는 것이다.Then, the supporting rod 9 is inserted into the lower portion of the manhole cover 11 and pushed or pulled. Accordingly, the center support bar 1 is moved by the rolling motion of the wheel 3, and at the same time, the support rod 9 is rolled to easily detach the manhole cover 11 to the outside. On the contrary, when the manhole cover 11 is closed, the annular ring 8 is hung on the manhole cover 11 placed on the upper side of the support bar 9, and the center support bar 1 is pushed or pulled to the manhole position. Let's do it. And, when a part of the manhole cover 11 is inserted into the manhole, by pressing the center support bar (1) with the wheel (3) as a pedestal lifts the manhole cover 11 and removes the backing rod (9) and then closes it. .

이상에서 설명한 본 고안은 정술한 실시예 및 첨부된 도면에 의해 한정되는 것은 아니고, 본 고안의 기술적 사상을 벗어나지 않는 범위 내에서 여러가지 치환, 변형 및 변경이 가능함은 본 고안이 속하는 기술분야에서 통상의 지식을 가진자에게 있어 명백할 것이다.The present invention described above is not limited to the embodiments described and the accompanying drawings, and various substitutions, modifications, and changes are possible within the scope without departing from the spirit of the present invention is common in the art. It will be apparent to those who have knowledge.

전술한 바와 같이 본 고안에 따르면, 지렛대의 원리와 받침봉을 이용하여 통신용 맨홀뚜껑을 작업자가 작은 힘으로 쉽게 개폐시키므로써 인력의 과다손실을 막고 또한 개폐작업을 간단히 하여 작업효율을 향상시키며, 안전사고의 발생을 경감하는 효과를 가진다.As described above, according to the present invention, by using the principle of the lever and the support rod, the operator easily opens and closes the communication manhole cover with a small force, thereby preventing excessive loss of manpower and simplifying the opening and closing work, thereby improving work efficiency and safety. It has the effect of reducing the occurrence of accidents.
