Rolling support outside pipeline

The utility model relates to a pipeline outer rolling support which comprises a pipeline hoop piece, a pipeline supporting frame and idler wheels, the pipeline hoop piece is an annular hoop, the idler wheels are symmetrically and transversely installed on the two sides of the pipeline hoop piece, and the pipeline hoop piece is fixedly connected or detachably connected to the top of the pipeline supporting frame. And more than two rollers are vertically mounted at the bottom of the pipeline supporting piece. By the adoption of the pipeline outer rolling support, it is guaranteed that a pipeline can smoothly pass through a square culvert when passing through the square culvert, friction of the side wall is reduced, construction is convenient, and therefore construction efficiency is improved. The utility model is especially suitable for long-distance pipeline construction. 本实用新型涉及一种管道外滚动支架，包括管道抱箍件、管道支撑架和滚轮，所述管道抱箍件为环形抱箍，管道抱箍件的两侧对称地横向安装有滚轮，管道抱箍件固定连接或可拆卸连接于管道支撑架的顶部，管道支撑件的底部竖向安装有两个以上滚轮。采用本实用新型所述的管道外滚动支架，保证了管道在穿越方形涵
