본 발명은 맨홀부재용 집게 관한 것으로, 더욱 상세하게는 중량이 나가는 맨홀 받침틀과 뚜껑으로 구성된 맨홀부재를 집게로 파지한 후 연결된 와이어를 중장비가 들어올려 운반되도록 한 맨홀부재용 집게에 관한 것이다.The present invention relates to a manhole member tongs, and more particularly, to a manhole member tongs for carrying heavy equipment is carried by lifting the connected wire after holding a manhole member consisting of a heavy weight manhole support frame and a lid with forceps.

종전 통신케이블 공사 및 저수변 작업 현장 등에서는 흔히 중량체인 맨홀 뚜껑을 개폐하기 위해서는 곡괭이 및 지렛대, 갈고리로 맨홀뚜껑의 홀에 삽입한 후 들어 이탈시키는데, 이때 여러 작업자가 투입되어 맨홀을 이동시키거나 역순으로 맨홀뚜껑을 들어올려 닫는 실정이다. 이같이 반복되는 일들이 현장 작업인들에게는 매우 곤혹스러운 일로 여겨졌었다.In the past, such as communication cable construction and waterside work sites, in order to open and close the heavy chain manhole cover, it is inserted into the hole of the manhole cover with a pickaxe, crowbar, and hook, and then lifted off. The situation is closed by lifting the manhole cover. This repetition was considered very embarrassing to field workers.

그리고 맨홀을 시공 후 맨홀 받침틀과 뚜껑을 동시에 올려놓는 작업은 다수의 작업인원만으로는 할 수 없어 중장비를 동원하여 하는데, 이때 맨홀 받침틀과 뚜껑을 간단히 파지할 수 없어 와이어나 밧줄을 이용하여 들어올린 후 작업자들이 자세를 잡아준 후 시공을 하게 된다.And the manhole support frame and the lid at the same time after the construction of the manhole can not be done by a large number of workers alone to mobilize heavy equipment, in which case the manhole support frame and lid can not be easily gripped by lifting the wire using a rope or a worker After the postures are set, they will begin construction.

맨홀부재의 설치에 따른 작업에 중장비와 다수의 작업인원을 사용 작업함에 따라 시공비용의 상승이 초래되어 원가 상승과 뿐만 아니라 작업이 신속하게 이루어지지 못한 문제점이 있었다.The use of heavy equipment and a large number of workers in the work according to the installation of the manhole member resulted in an increase in construction cost, and there was a problem in that the work was not performed quickly as well as the cost increase.

이 때문에 발주자나 시공사 모두 작업이 비효율적으로 운영됨에 따라 공사비 의 상승을 가져오는 문제점이 있었다.For this reason, there was a problem that both the owner and the contractor resulted in an increase in construction cost because the work was inefficiently operated.

Accordingly, when the manhole member 50 is to be lifted up, it is placed in the center line of the manhole member 50 as it is in the open state and then lifted up, and the clamping portion 10 is tightened by its own weight.

상기 치판(11)은 측 단면 형상이 디귿 자로 형성되고, 맨홀부재(50)의 파지가 용이하게 치끝(12)에 일정 곡률의 파지홈(13)이 형성된다. 그리고 치판(11)을 일정 면적으로 형성되고 있어 중심 선상에 간단히 위치시켜 놓는 것이 가능하다. 또 치판(11)이 면적을 갖고 있음에 따라 면접촉이 증대되어 안정된 자세로 들어올릴 수 있게 된다. The tooth plate 11 has a side cross-sectional shape formed of a recess, and a grip groove 13 having a predetermined curvature is formed at the tooth tip 12 to easily grip the manhole member 50. And the tooth plate 11 is formed in a predetermined area, and it is possible to simply position it on the center line. In addition, as the tooth plate 11 has an area, the surface contact is increased, so that the tooth plate 11 can be lifted in a stable posture.

또 치판(11)은 높이(14)를 조정하면 다양한 종류의 맨홀부재를 들어올리는 것도 가능하다.The tooth plate 11 can also lift various types of manhole members by adjusting the height 14.

상기 조임부(30)에는 치판(11)의 벌어짐이 유지되도록 가장자리에 스톱퍼(31)가 형성된다. 상기 스톱퍼(31)는 치판(11)을 벌려 놓을 상태로 위치시켜 세워놓는 것을 가능하게 하며, 이어지는 작업에 신속히 대응할 수 있게 한다.A stopper 31 is formed at the edge of the tightening part 30 to maintain the gap of the tooth plate 11. The stopper 31 allows the tooth plate 11 to be placed in a state in which the tooth plate 11 is to be opened, and to stand up, and to quickly respond to subsequent work.

상기 집게(2)는 집게부(10)와 힌지부(20)사이가 꼬여 치판(11)을 형성하게 된다. 이는 내구성을 높이기 위하여 일체인 하나의 소재로 제작된다. 즉, 다른 소재를 이용한 용접 없이도 하나의 편만으로 제작된다. The tongs 2 are twisted between the tongs 10 and the hinge 20 to form the tooth plate 11. It is made of a single material to increase durability. In other words, it is manufactured with only one piece without welding using different materials.

상기 치판(11) 간의 간격은 맨홀을 집을 수 있는 간격으로 벌려질 수 있으면 된다.The spacing between the tooth plate 11 may be widened at intervals for picking up the manhole.

상기한 바와 같이 이루어지는 본 발명의 작용을 설명하면, 치판(11)간을 벌린 상태에서 들어올릴 맨홀부재(50)의 외곽에 위치시켜 둔다. 이때 맨홀부재(50)의 중심 선상에 위치되도록 한다.When explaining the operation of the present invention made as described above, it is placed on the outer side of the manhole member 50 to be lifted in a state in which the tooth plate 11 is opened. At this time, to be positioned on the center line of the manhole member 50.

그리고 나서 미리 조임부(30)의 단부에 연결된 클램프(40)에 연결된 와이어(41)를 이용 무게중심이 맞도록 중장비에 걸은 후, 예비동작을 통해 치판(11)의 파지홈(13)이 맨홀부재(50)의 외주면에 정확히 밀착시킨다.Then, the wire 41 connected to the clamp 40 connected to the end of the tightening part 30 is hooked to the heavy equipment so that the center of gravity fits, and then the gripping groove 13 of the tooth plate 11 is manhole through a preliminary operation.
