도 4는 도 3의 A-A'선 단면예시도. 4 is a cross-sectional view taken along the line AA ′ of FIG. 3.

본 발명은 관체 용접용 로테이터에 관한 것이다. The present invention relates to a rotator for pipe welding.

보다 상세하게는 관체를 받쳐 줌과 동시에 저속회전시켜주는 한 쌍의 받침롤러에 동력을 전달함에 있어서, 동력전달구성이 동체 내부에 위치하게끔 구성하여 단정한 외관을 구현함과 동시에 작업시 안전사고를 예방하고, 더불어 용접하고자 하는 관체의 크기에 따라 한 쌍의 받침롤러를 이송시켜 그 간격을 벌리거나 오므릴 때 매우 신속간편하면서도 안정적으로 할 수 있게 함으로서 안전성과 신뢰성을 극대화시킬 수 있게 하기 위한 것이다.More specifically, in transmitting power to a pair of support rollers that support the tube and rotate it at low speed, the power transmission configuration is located inside the fuselage to realize a neat appearance and safety accidents during work. It is to prevent safety and to maximize the safety and reliability by transporting a pair of supporting rollers according to the size of the pipe to be welded so that it can be very quick and easy when opening or closing the gap.

주지된 바와 같이 로테이터는 관체와 관체를 용접 연결하거나 관체 선단 또는 소정위치에 플렌지를 용접 연결하거나 또는 관체 선단에 엘보우나 티형관 등을 용접 연결할 때 등 주로 원통형의 관체를 안정적으로 안착시켜 저속회전시켜줌으로서 안정적인 용접을 할 수 있게 유도하는 장치를 말한다.As is well known, the rotator makes a stable rotation of a cylindrical tube such as when welding a tube to a tube, welding a flange to a pipe tip or a predetermined position, or welding an elbow or a tee tube to a pipe tip. It refers to a device for inducing stable welding.

한편, 종래의 로테이터는 한 쌍의 받침롤러 각각의 축 선단에 체인휠을 설치하여 모터 및 감속기를 통하여 전달되는 동력이 체인에 의해 체인휠에 전달됨으로서 받침롤러가 저속으로 균일하게 회전되게 하였으며, 더불어 받침롤러의 간격조절을 가능하게 하기 위해 장력조절장치의 이송폭을 크게 구성하여 받침롤러의 회전과 간격조절이 상기 체인 및 장력조절장치 그리고 받침롤러의 유기적인 작용에 의해 이루어질 수 있도록 구성되어 있다.On the other hand, in the conventional rotator, the chain wheel is installed at the tip of each shaft of the pair of support rollers so that the power transmitted through the motor and the reducer is transmitted to the chain wheel by the chain so that the support rollers are uniformly rotated at low speed. In order to enable adjustment of the spacing of the support roller, the feed width of the tension control device is largely configured so that the rotation and spacing of the support roller can be achieved by the organic action of the chain and the tension control device and the support roller.

그러나 상기한 종래의 로테이터는 다음과 같은 문제점이 필연적으로 따랐다.However, the above conventional rotator inevitably has the following problems.

즉, 한쌍의 받침롤러 전방으로 동력을 전달하는 체인 및 체인휠 등의 동력전달구성이 노출되어 있는 상태이기에 작업과정에서 작업자의 옷자락이나 장갑 등이 끼거나 걸리게 되어 안전사고가 발생될 염려가 매우 높은 등의 폐단이 따랐고, 더불어 용접하고자 하는 관체의 직경이나 형상에 따라 받침롤러의 간격을 조절하고자 할 때는 먼저 장력조절장치를 풀어 체인이 느슨하게 한 다음 받침롤러를 인위적으로 이송시켜 조절 고정시키고, 이어서 느슨한 장력조절장치를 다시 팽팽하도록 조절하는 구성임에 따라 관체직경이나 형태에 따른 받침롤러의 간격조절이 매우 번거롭고 불편하였음은 물론 조절에 따른 시간이 과다소요되어 작업효율이 떨어지면서 생산성 또한 크게 떨어지는 등의 문제점이 따랐다는 것이다. In other words, since the power transmission components such as the chain and chain wheel that transmit power to the front of the pair of support rollers are exposed, there is a high risk of safety accidents caused by the worker's hem or gloves being caught or caught in the working process. If you want to adjust the distance between the supporting rollers according to the diameter or shape of the pipe to be welded, first loosen the tension adjusting device to loosen the chain, then artificially transfer the supporting rollers to fix and fix them, and then loosen them. Since the tension adjusting device is adjusted to be taut again, it is very cumbersome and inconvenient to adjust the spacing of the supporting rollers according to the pipe diameter or shape. The problem followed.

따라서 본 발명은 전술한 종래의 제반문제점을 감안하여 발명한 것으로서, 특히 받침롤러를 회전시키기 위한 동력전달구성과 받침롤러의 간격조절구성을 이원화시켜 안정적인 동력전달이 이루어지게 함은 물론 한 쌍의 받침롤러를 양방향스크류우로서 동시에 벌리거나 오므릴 수 있게 하여 간격조절이 매우 신속간편하게 이루어지는 로테이터를 제공하려는데 그 목적이 있는 것이다. Therefore, the present invention has been invented in view of the above-mentioned conventional problems, and in particular, the power transmission configuration for rotating the support rollers and the spacing control configuration of the support rollers are dualized to allow stable power transmission, as well as a pair of support. It is an object of the present invention to provide a rotator in which the gap can be adjusted very quickly and easily by allowing the roller to be opened or closed simultaneously as a bidirectional screw.

한 쌍의 받침롤러(2)는 각각 양측에 마찰부(21)가 형성되면서 중앙부에는 하부에 치합된 웜(22)에 의해 회전방향을 90°로 변화감속시켜주면서 받침롤러(2)의 저속회전을 유도하는 웜휠(23)이 각각 장착되고, 상기 한 쌍의 받침롤러(2) 각각에 동력을 전달하는 웜(22)의 중앙부 축공(24)에는 키이의 작용과 함께 가이드의 작용을 동시에 수행하는 수평키이(25)를 장착 고정시켜, 이 곳에 선단에 체인휠(31)이 장착되고 길이 방향으로 길게 키이용 가이드홈(32)을 가진 장축(3)을 삽입 관통시킴으로서 동체(1) 내부에 설치된 모터(16) 및 감속기(16')의 동력을 체인(17)을 통하여 장축(3)이 전달받아 받침롤러(2)를 안정적으로 회전시킬 수 있게 한 것이다. The pair of supporting rollers 2 are formed at both sides of the friction rollers 21, respectively, and the lower portion rotates at a low speed while the rotational direction is reduced by 90 ° by the worm 22 engaged at the lower portion of the supporting rollers 2. Each of the worm wheels 23 for guiding the worm wheels 23 is mounted, and the central shaft hole 24 of the worm 22 which transmits power to each of the pair of supporting rollers 2 simultaneously performs the action of the guide together with the action of the key. The horizontal key 25 is mounted and fixed, and the chain wheel 31 is mounted at the tip and inserted into the fuselage 1 by inserting the long shaft 3 having the key guide groove 32 in the longitudinal direction. Power of the motor 16 and the reducer 16 ′ is transmitted to the long shaft 3 through the chain 17 so that the support roller 2 can be stably rotated.

또, 상기한 한쌍의 받침롤러(2)는 한 쌍의 가이드레일(43)을 타고 이송조절되게 하되, 상기 한 쌍의 받침롤러(2)에는, 받침롤러(2) 각각의 양 측단부에 하단에 안내단턱(26')을 가진 수직프레임(26)을 설치하되 상기 안내단턱(26')과 소정의 간격을 유지하여 양측 수직프레임(26)을 연결시킴과 동시에 중앙 상면에는 웜(22)을, 그리고 저면에는 너트 즉, 암나사관(27)을 장착 구성한 지지프레임(28)으로 이루어진 롤러프레임(29)을 설치구성하여 상기 안내단턱(26')과 지지프레임(28)이 가이드레일(43)의 저면과 상면에 마찰 이송되게 한 것이다.In addition, the pair of support rollers (2) is to be transported and controlled by a pair of guide rails 43, the pair of support rollers (2), the lower end of both side ends of each of the support rollers (2) A vertical frame 26 having a guide step 26 'is installed on the vertical frame 26', while maintaining a predetermined distance from the guide step 26 'to connect both vertical frames 26, and at the same time, a worm 22 is provided on the center upper surface. In addition, the guide frame (26 ') and the support frame (28) is formed by installing the roller frame (29) consisting of a support frame (28) on which a nut, that is, a female thread pipe (27), is mounted on the bottom surface.

미 설명 부호 6은 웜휠 캡이다.Reference numeral 6 is a worm wheel cap.

이와 같이 구성된 본 발명의 로테이터(100)는 한 쌍의 받침롤러(2)를 구동시키는 구성은 물론 관체(P)의 크기에 따라 상기 받침롤러(2) 각각을 동시에 이송시켜 간격을 벌리거나 오므리는 구성이 모두 동체 내부에 위치하도록 구성되어 있기 때문에 조작 또는 작동과정에서 작업자의 신체나 옷자락 등이 걸리는 등의 안전사고 발생 염려가 전혀 없고, 동시에 관체직경의 크기에 따른 받침롤러(2)의 간격조 절이 매우 손쉽게 이루어지는 특징이 따르게 된다.The rotator 100 of the present invention configured as described above is configured to drive a pair of support rollers 2 as well as to simultaneously transport or support each of the support rollers 2 according to the size of the tubular body P. Since the components are all located inside the fuselage, there is no concern about the occurrence of safety accidents such as the body or the hem of the worker being caught during the operation or operation, and at the same time, the gap between the supporting rollers 2 according to the size of the pipe diameter. The feature is that the clause is very easy to follow.

즉, 종래에는 한 쌍의 받침롤러 각각의 축에 체인휠(도시하지 않음)을 장착하고 상기 각각의 체인휠과 모터축에 장착된 체인휠(도시하지 않음)을 체인(도시하지 않음)으로 연결함과 동시에 상기 체인에 장력을 유지시켜 줌과 동시에 받침롤러의 간격조절을 원활하게 할 수 있게 하기 위해 장력조절기(도시하지 않음)를 설치함으로서 체인휠과 체인, 장력조절기 등이 모두 동체(1) 외부로 노출되는 등의 문제점이 따랐던 것이지만, 본 발명에서는 한 쌍의 받침롤러(2)에 동력을 전달함에 있어서, 받침롤러(2) 각각의 중앙부에 웜휠(23)을 장착 구성함과 동시에 상기 각각의 웜휠(23)에 웜(22)이 치합되고, 더불어 상기 각각의 웜(22)에는 선단에 체인휠(31)이 장착됨과 동시에 키이용가이드홈(32)이 길게 형성된 장축(2)이 관통설치되어 있는 상태임으로 동체(1) 내부에 설치된 모터(16)의 동력이 감속기(16')를 통하여 감속된 상태에서 체인(17)에 의해 체인휠(31)을 회전시키게 됨에 따라 장축(3)이 회전하면서 궁극적으로 받침롤러(2)를 회전시킬 수 있게 되기 때문에 종래 처럼 받침롤러를 회전시키기 위한 체인휠이나 체인 등의 외부노출이 전혀 없게 되어 안전성이 극대화되면서 외관이 깔끔하게 유지된다는 것이다. That is, in the related art, a chain wheel (not shown) is mounted on each shaft of a pair of support rollers, and the chain wheel (not shown) mounted on each of the chain wheels and the motor shaft is connected by a chain (not shown). Simultaneously, the chain wheel, the chain, the tension controller, etc. are all installed by installing a tension regulator (not shown) to maintain tension on the chain and to smoothly adjust the spacing of the support roller. In the present invention, the worm wheel 23 is mounted at the center of each of the support rollers 2, and the respective worm wheels 23 are mounted at the center of the support rollers 2. The worm 22 is engaged with the worm wheel 23 of the worm wheel 23. In addition, the worm 22 is fitted with a chain wheel 31 mounted at the distal end of the worm wheel 23, and a long shaft 2 having a long keyed groove 32 is penetrated therethrough. Inside the fuselage (1) in the installed state As the chain wheel 31 is rotated by the chain 17 while the power of the installed motor 16 is decelerated through the reducer 16 ', the long shaft 3 rotates and ultimately the support roller 2 is rotated. Since it can be rotated, there is no external exposure such as a chain wheel or a chain for rotating the support roller as in the prior art, thereby maximizing safety and maintaining the appearance neatly.

따라서 상기 받침롤러에 관체(P)를 안착시킨 상태에서 수작업 또는 자동으로 피용접물인 관체이음 또는 플렌지이음을 위해 용접할 경우 안전성이 크게 향상되는 것이며 외관이 단정한 등의 특징이 따르게 된다는 것이다.Therefore, when welding for pipe joints or flange joints, which are welded by hand or automatically in a state in which the tubular body (P) is seated on the support roller, safety is greatly improved and appearance is neat.

또, 용접하고자 하는 관체(P)가 더 커지거나 작아짐에 따라 한 쌍의 받침롤러(2)를 벌리거나 오므리는 방향으로 이송조절하고자 할 때는 육각머리(41)를 가진 스크류우(4)를 시계방향 또는 반시계방향으로 돌려주면 되는데, 이때는 육각홈을 가진 렌치(도시하지 않음)를 이용하여 스크류우(4)를 시계방향 또는 반시계방향으로 회전시키면 스크류우(4) 자체에 오른나사부 및 왼나사부가 일체로 형성된 상태이고, 더불어 상기 스크류우는 받침롤러(2)의 지지프레임(28) 저면에 고정되어 있는 암나사관(27)에 체결되어 있는 상태이기에 시계방향 또는 반시계방향으로 회전할 때 한 쌍의 받침롤러(2) 또한 서로 벌어지는 방향 또는 오므러드는 방향으로 동시에 동일한 거리만큼 이송조절되게 되는 것이다.Also, when the pipe P to be welded is larger or smaller, watch the screw 4 having a hexagonal head 41 to adjust the feed in the direction of opening or closing the pair of support rollers 2. Or counterclockwise rotation. In this case, if the screw right 4 is rotated clockwise or counterclockwise using a wrench (not shown) having a hexagonal groove, the right and left threads of the screw right 4 itself are rotated. It is a state in which the unit is integrally formed, and when the screw is rotated in the clockwise or counterclockwise direction because it is fastened to the female threaded pipe 27 fixed to the bottom of the support frame 28 of the support roller 2. The supporting roller 2 is also to be controlled to be fed at the same time in the direction of spreading or retracting the same distance at the same time.

또, 상기와 같이 스크류우(4)를 시계방향 또는 반시계방향으로 회전시켜 받침롤러(2)를 이송시키는 과정에서 상기 받침롤러(2)와 일체로 구성된 웜휠(23)을 회전시키기 위한 웜(22)에는 수평키이(25)가 장착 고정되어 있고 상기 웜(22)을 회전시키는 장축(3)에는 길이방향으로 키이용가이드홈(32)이 길게 형성된 상태임으로 받침롤러(2)가 자체회전과 더불어 키이용가이드홈(32)을 따라 이송이 가능하게 되는 특징이 따르게 된다. In addition, a worm for rotating the worm wheel 23 integrally formed with the support roller 2 in the process of transporting the support roller 2 by rotating the screw right 4 clockwise or counterclockwise as described above. 22, the horizontal key 25 is fixed and the support shaft (2) is self-rotating and the long axis (3) for rotating the worm 22 is formed in the longitudinal direction of the key guide groove 32 in the longitudinal direction In addition, the feature is to be transported along the key guide groove (32).

따라서 스크류우(4)를 회전시키면 한 쌍의 받침롤러(2)가 안정적으로 벌어지거나 오므러드는 방향으로 이송조절될 수 있게 되는 것이며, 따라서 관체 크기에 따라 받침롤러(2)의 간격조절을 매우 신속정확하게 할 수 있게 된다. Therefore, when the screw 4 is rotated, the pair of support rollers 2 can be stably opened or retracted in the direction of movement, and accordingly, the adjustment of the space between the support rollers 2 is very large depending on the tube size. It can be done quickly and accurately.

상술한 바와 같이 본 발명은 받침롤러(2)를 회전시키기 위한 동력과 간격조절구성이 이원화됨과 동시에 동력전달에 있어 필수구성인 장축(3)에 키이용가이드홈(32)이 길게 형성되어 있고 웜(22)에 수평키이(25)가 설치되어 있어 스크류우(4) 회전시 받침롤러(2)가 장축(3)을 타고 이송조절되게 되어 용접하고자 하는 관체(P)의 직경이나 형태에 따른 간격조절이 매우 신속정확하게 이루어질 수 있으며, 더불어 동력전달에 따른 구성이 동체(1)의 내부측에 위치하게 됨에 따라 외관이 매우 깔끔함과 동시에 작업자의 옷자락이나 소매자락 또는 장갑 등이 끌려 들어가게 되어 발생되는 안전사고를 사전에 예방할 수 있는 등의 특징이 따르게 되는 매우 유용한 발명인 것이다. As described above, in the present invention, the power and the space adjusting configuration for rotating the support roller 2 are dualized and at the same time, the key guide groove 32 is formed in the long axis 3 which is an essential component for power transmission, and the worm Horizontal key 25 is installed on the 22 so that the support roller 2 is transported and adjusted along the long shaft 3 when the screw 4 is rotated, and thus the gap according to the diameter or shape of the pipe P to be welded. The adjustment can be made very quickly and precisely, as the configuration according to the power transmission is located inside the fuselage 1, the appearance is very neat and the safety caused by the worker's hem, sleeves or gloves are drawn in. It is a very useful invention that comes with features such as preventing accidents in advance.
