본 고안은 원통형작업물의 이송용집게(Tongs)에 관한 것으로 특히 죠오(Jaw) 일체의 하부링크를 역행없이 안내로를 따라 일주하는 회전핀일체의 피스톤의 승강으로서 벌리거나 좁히도록 하여 원통형 작업물을 집을 수 있도록 하는 원통형작업물의 이송용집게에 관한 것이다.The present invention relates to the transfer tongs of cylindrical workpieces. In particular, the lower links of the jaws are opened or narrowed by lifting and narrowing the pistons of the rotary pins that circulate along the guide path without backing. The present invention relates to a tong for conveying a cylindrical workpiece that can be picked up.

종래에 알려진 작업물 이송용 집게로는 일본국 공개실용신안공보소 58-1069호와 같은 것이 공지되어 있었다.Conventionally known work transfer tongs are known, such as Japanese Laid-Open Utility Model Publication No. 58-1069.

즉, 상부 접속블럭과 하부고정레바 사이에 양측으로 레버와 걸림레바를 핀으로 연결하여 벌리거나 좁혀지도록 하고 그와 같은 접속블럭의 중앙에는 스프링으로 탄발되는 피스톤을 장치하여 상기 고정레바 사이에 실린더로서 축지하여 피스톤의 돌기가 90간격으로 회전될때마다 레바와 걸림레바가 벌려지거나 좁혀져 걸림레바의 하단이 작업물의 걸림부에 걸려지도록 하는 것이 알려져 있었다.In other words, between the upper connection block and the lower fixing lever by connecting the lever and the locking lever to the pins on both sides so as to be opened or narrowed. 90 degrees of piston projection by moistening It is known that the lever and the locking lever are opened or narrowed every time the interval is rotated so that the bottom of the locking lever is caught by the catch of the workpiece.

그러나 이와 같은 이송용 집게장치는 걸림레바의 걸림턱에 걸려지는 작업물의 걸림부분이 필수적으로 수반되어야 하므로 결국 원통형 둥근주면을 갖는 작업물의 집게장치로는 부적당한 문제점이 있었다.However, such a transfer forceps device has to be accompanied by a catching part of the workpiece caught on the locking jaw of the locking lever is essentially an inadequate problem as the clamping device of the workpiece having a cylindrical round surface.

뿐만 아니라 이와같은 구조가 작동되기 위해서는 피스톤의 돌기가 90회전될때마다 레바와 걸림레바가 바깥 또는 안쪽으로 구부러져야 하며 이경우 90회전의 방향이 좌, 우 임의 방향으로 회전되게 되어있어 그방향에 따른 레바의 구부러짐도 임의대로 되어 걸림부안쪽 또는 바깥쪽으로 정해지지 않고 걸리게 되는 사용상의 문제점이 있었다.In addition, in order for this structure to work, the piston Each time it is rotated, the lever and the latch should be bent outward or inward. Since the direction of rotation is to be rotated in any of the left and right directions, the bending of the lever according to the direction is also arbitrary, there is a problem in use that is caught without being fixed to the inside or the outside of the locking portion.

본 고안의 원통형 작업물의 이송용집게 장치를 새로이하고 더불어 피스톤과 실린더의 승강작동의 구조를 간단하고도 확실한 작동을 하도록 하고자 하는데에 그목적이 있다.The purpose of the new tong device for conveying the cylindrical workpiece of the present invention is to make the structure of the lifting operation of the piston and the cylinder simple and reliable.

이를 첨부도면에 따라 상세히 설명하면 다음과 같다.This will be described in detail with reference to the accompanying drawings.

본 고안은 대, 소직경의 작업물(13)(13')을 집는 죠오(Jaw)(1)가 일체로된 X자형 하부링크(2')와, 고리(4)와 연결되는 상부링크(2)와, 이 상, 하링크(2)(2')를 작동시키는 실린더(5) 및 피스톤(6)으로 구성된다.The present invention is an X-shaped lower link (2 ') in which a jaw (1), which picks up a large-diameter workpiece (13) (13'), is integrated, and an upper link (14) connected to the ring (4). 2) and a cylinder 5 and a piston 6 for operating the lower link 2 and 2 '.

죠오(1)는 제5도와 같이 작업물(13)(13')의 직경크기에 따라 선택되어 하부링크(2')하단에 핀(11)으로 조립되는 구조를 갖이며 하나의 죠오(1)는 약 2개의 서로 다른 직경을 갖는 작업물을 집어올릴 수 있다. (실린더의 구조에 의함)The jaw (1) is selected according to the diameter size of the workpiece 13 (13 ') as shown in FIG. 5, and has a structure in which the pin 11 is assembled under the lower link (2'). Can pick up workpieces having about two different diameters. (By the structure of the cylinder)

이와같은 죠오(1)가 조립체결된 X자형 하부링크(2')는 핀(3)으로 상부링크(2)와 연결되고, X자형의 중심축지점에는 핀(3')이 피스톤(6)의 하부와 함께 축지된다.The X-shaped lower link 2 'in which the jaw 1 is assembled is connected to the upper link 2 by the pin 3, and the pin 3' is connected to the piston 6 at the central axis of the X-shape. It is moistened with the lower part of it.

상부링크(2)는 고리(4)에 핀(3'')으로 축지되고 피스톤(6)이 삽입된 실린더(5)의 상부역시 고리(4)에 상부가 현착축지되고 실린더(5)는 제2도 및 제3도와같이 일차걸림턱(10a), 이차걸림턱(10b), 정상부(10c), 풀림부(10d)를 이루는 안내로(10)를 형성하되 일차걸림턱(10a)을 지나 이차걸림턱(10b)전까지를 A구역으로 하고, 이차걸림턱(10b)를 포함하여 정상부(10c)까지는 B구역으로 한다.The upper link 2 is pinned to the ring 4 with a pin 3 '' and the upper portion of the cylinder 5 with the piston 6 inserted therein is also superimposed on the ring 4 and the cylinder 5 is removed. As shown in FIGS. 2 and 3, a guide path 10 constituting the primary locking jaw 10a, the secondary locking jaw 10b, the top portion 10c, and the unwinding portion 10d is formed, but passes through the secondary locking jaw 10a. The area up to the locking step 10b is defined as the A zone, and the area up to the top portion 10c is the zone B including the secondary locking step 10b.

즉, A구역과 일차걸림턱(10a)에는 보다 적은 직경으로 죠어(1)가 벌어질 경우의 작동로이고 B구역과 이차걸림턱(10b)은 보다 큰 직경의 작업물을 집고자 벌어질 경우의 작동로를 나타낸다. 이와같은 안내로(10)를 따라 안내되는 회전핀(8)은 피스톤(6)에 환착된 회전링(7)에서 돌출 구성되어 있다. 즉, 피스톤(6)은 일측단부측으로 회전핀(8)이 구성된 회전링(7)을 환착시킨뒤 록너트(9)으로서 고정하여서된 것으로 회전핀(8)이 안내로(10)상에 위치하게 실린더(5)에 삽입하게 된다. 미설명부호 12는 크레인 또는 호이스트의 후크이다. 이와같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.That is, in the case where the jaws 1 are opened with a smaller diameter in the zone A and the primary jaw 10a, the operation zone when the jaws 1 are opened in the zone A and the secondary jaw 10b is opened to pick up the workpiece having a larger diameter. Indicates the operation of. The rotary pin 8 guided along the guide path 10 is configured to protrude from the rotary ring 7 returned to the piston 6. That is, the piston (6) is to return the rotary ring (7) consisting of the rotary pin (8) to one side end side and fixed as a lock nut (9), the rotary pin (8) is located on the guideway (10) It is inserted into the cylinder (5). Reference numeral 12 is a hook of the crane or hoist. Referring to the effect of the present invention configured as described above are as follows.

크레인 또는 호이스트의 후크(12)를 고리(4)에 걸고 크레인이나, 호이스트를 운전하여 고리(4)를 누르면 하부링크(2')의 핀(3')과 상부링크(2)의 핀(3") 사이가 좁아지므로 피스톤(6)이 실린더(5)내로 점차로 들어가게 되며 동시에 피스톤(6)의 회전링(7)에 일체로된 회전핀(8)이 풀림부(10d)로부터 A구역쪽으로 상승되며 따라서 죠오(1)의 간격이 점차 벌어지게 된다.Hook the hook 12 of the crane or hoist to the hook 4 and drive the crane or hoist to press the hook 4 to release the pin 3 'of the lower link 2' and the pin 3 of the upper link 2 ") Becomes narrower, the piston (6) gradually enters the cylinder (5), and at the same time the rotary pin (8) integral with the rotary ring (7) of the piston (6) rises from the release portion (10d) toward the A zone. Therefore, the gap of the jaw (1) is gradually opened.

이때 회전핀(8)이 A구역에 위치할때 고리(4)를 누르면 작동을 정지함과 동시에 들어올리면 죠오(1)의 무게에 의해서 피스톤(6)이 하강되어 회전핀(8)이 걸림턱(10a)에 걸려 있게 된다. 이 상태는 죠오(1)의 간격이 작업물(13)직경보다 커지게된 상태로 작업물(13)이 쉽게 죠오(1)내에 들어오게 되며 작업물(13)을 완전하게 집기 위해서는 다시 고리(4)를 눌러 회전핀(8)이 안내홈(10)의 일차걸림턱(10a)을 지나 A구역 B구역을 거쳐 정상부(10c)에 위치되도록 한뒤 고리(4)를 누르던 작동을 정지함과 동시에 들어올리면 회전핀(8)이 정상부(10c)에서 역행되지 않고 풀림부(10d)쪽으로 하강되어 일정위치에 정지하게 된다.At this time, when the rotating pin (8) is located in the A zone, press the hook (4) to stop the operation and at the same time lift the piston (6) by the weight of the jaw (1) to lower the rotating pin (8). It is caught in (10a). In this state, the gap of the jaw (1) becomes larger than the diameter of the workpiece (13), the workpiece 13 easily enters the jaw (1), and in order to completely pick up the workpiece (13) 4) by pressing the rotary pin (8) through the primary catching jaw (10a) of the guide groove 10 through the A zone B zone to the top portion (10c) and stop the operation of pressing the ring (4) and At the same time, the lifting pin 8 is lowered toward the unwinding portion 10d without being backed from the top portion 10c and stopped at a predetermined position.

따라서 죠오(1)가 작업물(13)을 빠지지 않게 집게된다. 작업물(13)을 죠오(1)로부터 분리시킬 경우에는 회전핀(8)이 풀림부(10d)에 위치한 상태에서 호이스트나 크레인을 내려 자중으로써 고리(4)를 누르면 회전핀(8)이 다시 상승되어 일차걸림턱(10a)에 걸리게 되므로 죠오(1)가 벌어져 작업물(13)의 분리가 이루어지게 된다. 또한, 작업물(13')의 직경이 클경우에는 (제6도 (a) 참조) 회전핀(8)의 일차걸림턱(10a), A구역을 지나 B구역의 이차걸림턱(10b)에 걸리도록 하여 죠오(1)의 벌림각을 최대로 할 수도 있다. 즉, 회전핀(8)이 B구역까지 상승되도록 고리(4)를 눌러주다가 B구역에 도달하면 크레인을 들어올려 회전핀(8)이 이차걸림턱(10b)에 걸리도록 하게되므로 일차걸림턱(10a)에 회전핀(8)이 걸려있을 때보다 핀(3')과 실린더 상부핀(3") 사이가 최대로 좁아지고 따라서 피스톤(6)과 핀(3) 사이의 거리도 멀어져 죠오(1)의 폭이 최대로 넓어질 수 있게 된다.Therefore, the jaw 1 is picked up so that the workpiece 13 does not fall out. In the case of separating the workpiece 13 from the jaw 1, when the rotary pin 8 is positioned at the release portion 10d and the weight 4 is pushed down by the hoist or the crane, the rotary pin 8 is pressed again. As it rises and is caught by the primary catching jaw 10a, the jaw 1 is opened to separate the workpiece 13. In addition, when the diameter of the workpiece 13 'is large (see FIG. 6 (a)), the primary catching jaw 10a of the rotary pin 8 and the second catching jaw 10b of the B section pass through the A section. The opening angle of the jaw (1) can be maximized. That is, while pressing the ring (4) so that the rotary pin 8 is raised to the zone B, and reaches the zone B, the lifting pin (8) is caught by the secondary locking jaw (10b) to lift the crane, so The distance between the pin 3 'and the cylinder upper pin 3 "is narrower than that when the rotating pin 8 is suspended in 10a), and thus the distance between the piston 6 and the pin 3 is further reduced. ) Width can be maximized.

따라서 한개의 죠오(1)에 따라 항상 두 가지의 서로 다른 직경을 갖는 작업물(13)(13')을 집을 수 있게되는 것인바, 죠오(1)를 제5도의(a), (b)와 같이 더욱 작은것 또는 더욱 큰것으로 교체할때마다 작업물(13)(13')의 직경을 두가지로 선택하여 작업할 수 있게되는 것이다. 또한 이차걸림턱(10b)에서 작업물(13')을 집을 경우에는 고리(4)를 눌러 정상부(10c)까지 도달하도록 한뒤 들어올리면 역행하지 않고 풀림부(10d)로 내려가 작업물(13')을 견고하게 집게 되며 작업물(13')을 집어 이송하고 난뒤에도 전술한 바와같이 다시 고리(4)를 눌러 풀림부(10d)로부터 일차걸림턱(10a)을 지나 이차걸림턱(10b)에 걸려지게 한뒤 들어올림으로써 간단히 작업물이 분리케되어 작업물(13')을 집고 이송한뒤 다시분리시키는 일주기의 작동을 완료하게 되는 것이다.Therefore, it is possible to pick up the workpieces 13 and 13 'having two different diameters according to one jaw 1, so that the jaw 1 is shown in FIGS. 5A and 5B. Whenever you replace it with a smaller or larger one, you can work by choosing two diameters of the workpiece (13) (13 '). In addition, in the case of picking up the workpiece 13 'from the secondary catching jaw 10b, pressing the hook 4 to reach the top portion 10c and then lifting it down to the unwinding portion 10d without lifting the workpiece 13'. After picking up and transporting the workpiece 13 'and pressing the hook 4 again as described above, it is caught by the secondary catching jaw 10b after passing through the primary catching jaw 10a from the unwinding portion 10d. By lifting up and lifting, the workpiece is simply separated to complete the work cycle of picking up and transporting the workpiece 13 'and then separating it again.

특히 본 고안은 안내로(10)를 따라 회전핀(8)이 안내되는 중에 한쪽방향(시계방향)으로만 순환안내되는 것으로 역행이되지 않는다.In particular, the present invention is not reversed by being circulated in only one direction (clockwise) while the rotating pin 8 is guided along the guide path 10.

이와같이 본 고안은 크레인이나 호이스트작업자 혼자서 원통형 작업물을 간단히 이송시킬 수 있는 고안으로 종래 걸림부분이 있는 작업물만을 이송하는 이송용집게장치가 갖는 문제점을 개선하여 부품수도 간단화하며 피스톤과 실린더의 작동구조도 새로이하여 원통형 작업물이송을 보다 편리하게한 효과가 있다.As such, the present invention is designed to easily transfer cylindrical workpieces by a crane or hoist worker alone, and improves the problem of the transfer clamp device for transferring only workpieces with conventional hooks, thereby simplifying the number of parts and operating pistons and cylinders. The new structure also makes it easier to transport cylindrical workpieces.
