Abstract

This paper introduces the design of a bridge transport system with a telescopic tube for positioning equipment to perform remote handling tasks in a radioactive facility. It consists of an extensible and retractable telescopic tube assembly for z-direction motion, a cabling system for management of power and signal cables, and a trolley system for transverse motion and accommodating servo drives. The working environment for the bridge transport system with the telescopic tube requires strict geometrical constraints, including a short height, short telescopic tube length when retracted, and a long stroke. These constraints were met by solving a nonlinear programming problem involving the optimal dimensions. This paper introduces a cabling system for effective management of cables with changeable lengths to accommodate telescopic motions and a selection guide for servo drives that are sufficient to drive the system.

본 논문은 방사성시설에서 원격취급 작업을 위해 사용되는 서보조작기와 같은 장비의 이송을 위해 개발된 텔레스코픽 튜브를 갖는 천정이동장치의 설계에 관해 소개한다. 천정이동장치는 z-방향으로 신장, 수축이 가능한 텔레스코픽 튜브, 전력 및 신호 케이블의 관리를 위한 케이블 시스템, 횡행 움직임과 서보구동부 모듈수납을 위한 트롤리 시스템으로 이루어져 있다. 천정이동장치의 작업환경은 설계에 기하학적인 제약을 주게 되는데, 시설의 높이가 낮고 텔레스코픽 튜브의 수축시 길이가 짧아야하며 스트로크는 커야한다는 요구사항을 갖는다. 텔레스코픽 튜브 어셈블리는 위 제약조건을 만족하도록 비선형계획법을 풀어 최적의 치수를 선정하였다. 텔레스코픽 모션으로 발생하는 케이블 길이의 변화를 수용할 수 있는 케이블 시스템을 소개하였고, 또한 천정이동장치 시스템의 충분한 구동을 위한 서보구동부의 선택지침을 소개하였다.
