The invention provides a telescopic device of a vacuum pipeline. The telescopic device comprises an arc-shaped annular plate, a supporting ring and a supporting cylinder. The arc-shaped annular plate circumferentially surrounds the outer side of a thermal expansion gap between the two sections of vacuum pipelines, the first end of the arc-shaped annular plate is fixedly connected with the outer surface of the first section of vacuum pipeline, and the second end of the arc-shaped annular plate is fixedly connected with the outer surface of the second section of vacuum pipeline; the supporting cylinder circumferentially surrounds the upper portion of the thermal expansion seam and is located on the inner side of the arc-shaped annular plate, one end of the supporting cylinder is fixedly connected with the first section of vacuum pipeline, and a first seam is formed between the other end of the supporting cylinder and the second section of vacuum pipeline; the supporting ring is arranged above the supporting cylinder in a surrounding mode, the top of the supporting ring is fixedly connected with the arc-shaped annular plate, and a second gap is formed between the bottom of the supporting ring and the outer surface of the supporting cylinder. The method can be better applied to vacuum pipelines with large sections or square sections.
本发明提供了一种真空管道的伸缩装置,包括:弧形环板、支撑环和支撑筒;所述弧形环板周向环绕在两段真空管道间的热膨胀缝的外侧,弧形环板的第一端与第一段真空管道的外表面固定连接,弧形环板的第二端与第二段真空管道的外表面固定连接;所述支撑筒周向环绕在热膨胀缝的上方,且位于弧形环板的内侧,支撑筒的一端与第一段真空管道固定连接,另一端与第二段真空管道间设置有第一缝隙;所述支撑环环绕设置在支撑筒的上方,且支撑环的顶部与弧形环板固定连接,支撑环的底部与支撑筒的外表面间设置有第二缝隙。应用本发明可以更好地适用于大截面或方形截面的真空管道。
