Abstract: Compared with the conventional two-sectioned friction guide plate, a new type guide plate of the spiral pipe plant is introduced here in the article. It features adoption of an intermediate connecting plate which turns the original two-sectioned structure into a three-sectioned one, and employment of the concave-convex stepped force transmission method. As a result, the intrinsic weak point to the original friction guide plate, i.e., excessive load the guiding plane bears, which leads to a trend to be deformed and sliding is solved effectively.
