The present invention relates to a ring frame alignment mounting device for a short pipe, and relates to a ring frame alignment mounting device for a short pipe that can be mounted by aligning the ring frame on a short pipe outer plate in order to weld the ring frame to the pressure pipe.

일반적으로 압력관인 경우 강도를 구비하기 위해서는 내부에 보강재가 붙으며, 그 구조는 형상의 특성상 원형의 보강재인 'Ｔ' 형상의 링 프레임 보강재가 사용되고 있다. 단관의 제작공정은 먼저 준비된 링 프레임을 정렬하고, 단관의 외판에 하나씩 순서대로 취부작업을 실시하게 되며, 다음 공정인 용접품질 때문에 갭 관리와 정확한 취부선에 링 프레임을 취부하는 것이 중요하다.In general, in the case of a pressure pipe, a reinforcement is attached to the inside to provide strength, and a structure of the ring frame reinforcement having a 'T' shape, which is a circular reinforcement, is used in its structure. In the manufacturing process of the short pipe, the prepared ring frame is arranged first, and the mounting work is performed on the outer plate of the short pipe one by one, and it is important to install the ring frame on the gap management and the correct mounting line because of the welding quality, which is the next process.

압력관 내부에 링 프레임의 취부는 대부분 수작업에 의존하고 있으며, 간이 치공구와 공장내에 설치된 크레인을 이용하여 작업부재를 고정하거나 작업시 다루고 있어서 안전을 위협하고 있다. 또한 전용장치가 없어 생산성 뿐만 아니라 용접을 위한 취부갭 관리와 취부선에 대한 링 프레임의 취부 맞춤 등의 정도관리에도 어려움과 문제점을 가지고 있었다. The mounting of the ring frame inside the pressure pipe is mostly dependent on the manual work, and the working tools are fixed or handled at the time using simple tools and cranes installed in the factory, which threatens safety. In addition, there was a difficulty and problem in not only the productivity but also the control of the mounting gap for welding and the control of the fitting of the ring frame to the mounting line because there is no dedicated device.

본 발명은 상기와 같은 문제점을 고려하여 이루어진 것으로, 그 목적은 단관 내면에 링 프레임를 정확한 위치로 정렬한 후 취부하여, 생산성 및 제작에 대한 정도관리를 향상시키며, 불량률을 저하시킴과 동시에, 작업자의 용이한 조작에 의해 작업능률 및 작업속도를 향상시킬 수 있는 단관의 링 프레임 정렬 취부장치를 제공하는 것이다.The present invention has been made in consideration of the above problems, and its purpose is to align the ring frame with the correct position on the inner surface of the short pipe and then install it, thereby improving the quality control for productivity and manufacturing, and reducing the defective rate, It is to provide a single frame ring frame alignment mounting apparatus that can improve the work efficiency and work speed by easy operation.
