AI Technical Summary
Technical Problem
The existing non-contact inverter has a short buffering time during the reverse stop, which may cause safety hazards.
Method used
A non-friction reverser with a double-stage dynamic rotation is designed. By setting multiple movable arc sleeves and bidirectional fan plates on the inner liner, the instantaneous reverse stop effect is achieved by using the cooperation of the limit stop and the give way fixed block.
Benefits of technology
The buffering time during the reverse stop process is effectively avoided, instantaneous reverse stop is achieved, and safety is improved.

Abstract
The utility model discloses a two-stage dynamic rotation non-friction backstop, which relates to the technical field of backstops, and comprises an outer bushing, an inner bushing and a plurality of special-shaped wedge blocks, the inner bushing is positioned in the outer bushing and is rotatably connected with the outer bushing, the special-shaped wedge blocks are arranged on the inner bushing, a plurality of movable arc sleeves are arranged on the lower side of the inner bushing, and the movable arc sleeves are arranged on the outer bushing. The multiple movable arc sleeves are arranged along the circle center point of the inner lining in an annular array mode, bidirectional sector plates are arranged in the movable arc sleeves and arranged in the length direction corresponding to the outer lining, and the center point positions of the upper side surfaces and the lower side surfaces of the bidirectional sector plates are rotationally connected with the movable arc sleeves. On the basis that the neck bush rotates, the movable arc sleeves are matched with the neck bush to perform adaptive rotation, and at the moment that the neck bush reversely rotates, the bidirectional sector plates are quickly matched with the limiting stop blocks, so that the reverse rotation process of the neck bush is directly limited by the movable arc sleeves; and the movable arc sleeve does not interfere with the rotating process of the neck bush.
