Safe anti-falling brake structure
The invention provides a safe anti-falling brake structure, which relates to the technical field of rolling door structures, and comprises a fixed bottom plate and a rotating cover plate, a ratchet wheel and a roller are arranged between the fixed bottom plate and the rotating cover plate, an accommodating cavity is formed in the inner side of the rotating cover plate, two sides of the upper end of the accommodating cavity are respectively provided with a limiting clamping groove, and the two limiting clamping grooves are symmetrically arranged; the curvature of the end, close to the upper end of the containing cavity, of the limiting clamping groove is larger than that of the end, away from the upper end of the containing cavity, of the limiting clamping groove, so that the roller is clamped between the ratchet wheel and the end of the limiting clamping groove under the action of centrifugal force, a stroke groove is formed in the upper end of the rotating cover plate, and a stroke switch matched with the stroke groove is arranged on the fixed bottom plate. The limiting clamping grooves symmetrically formed in the two ends are adopted, the bending radians of the two ends of the limiting clamping grooves are different, rotation of the roller in the two directions under the centrifugal force effect is effectively clamped, braking stress is more uniform, abrasion to the rotating cover plate is small, the service life is long, and multiple times of safe braking can be conducted.
本发明提供一种安全防坠制动结构，涉及卷门结构技术领域，包括固定底板和转动盖板，固定底板和转动盖板之间设有棘轮和滚柱，转动盖板内侧形成容纳腔，容纳腔上端的两侧分别设置有限位卡槽，两个限位卡槽对称设置，且限位卡槽靠近容纳腔上端的一端的弯曲度大于限位卡槽远离容纳腔上端的一端的弯曲度，使得滚柱在离心力作用下卡在棘轮和限位卡槽的端部之间，转动盖板上端设置有行程槽，固定底板上设置与行程槽配合的行程开关。本发明采用两端对称设置的限位卡槽，且限位卡槽两端的弯曲弧度不同，分别对滚柱在离心力作用下的两个方向的转动进行有效卡紧，制动受力更均匀，对转动盖板的磨损小，使用寿命长，可以进行多次安全制动。
