Description
Центратор работает следующим образом.The centralizer works as follows.
Ось нижнего звена 2 выдвигаетс из впадины фигурного паза рамки 3. При этом все звено опускаетс , и центратор освобождает трубу. Пружина 8, взаимодейству через толкатели 7 с рычагами 5, поднимает верхнее звено 1 над трубой на роликах 6.The axis of the lower link 2 extends from the hollow of the shaped groove of frame 3. At the same time, the whole link is lowered and the centralizer releases the pipe. Spring 8, interact through the pushers 7 with the levers 5, raises the upper link 1 above the tube on the rollers 6.
При перемещении центратора от стыка к стыку он может занимать различные наклонные положени . При этом также пружина 8 занимает различные положени в корпусе 9, а ролики 6 наход тс в посто нном контакте с поверхностью трубы, так как нри подъеме одного ролика противоположный ролик опуститс .When moving the centralizer from the junction to the junction, it can occupy various inclined positions. Moreover, the spring 8 occupies different positions in the housing 9, and the rollers 6 are in constant contact with the surface of the pipe, as the opposite roller is lowered when one roller is lifted.
После установки центратора на стык ось звена 2 вновь вводитс во впадину фигурного паза рамки 3. Силовой привод 4, перемеща рамку 3, производит зат жку центратора .After the centralizer is installed on the joint, the axis of the link 2 is reintroduced into the hollow of the figure of the groove of the frame 3. The actuator 4, moving the frame 3, tightens the centralizer.
При использовании наружного центратора предлагаемой конструкции значительно упрост тс операции перемещени центратора и установки его на стык, так как его перемещение может осуществл тьс по свариваемому трубопроводу, что особенноWhen using the outer centralizer of the proposed design, the operation of moving the centralizer and installing it at the joint is greatly simplified, since its movement can be carried out along the pipeline being welded, which is especially
важно в услови х труднопроходимой, болотистой и пересеченной местности.important in difficult, swampy and rough terrain.
При этом также сократитс врем сборки стыков магистральных трубопроводов.At the same time, the assembly time of the pipelines joints will also be shortened.
