Ratchet wheel positioning anti-falling climbing frame
The invention discloses a ratchet wheel positioning anti-falling climbing frame. The frame comprises a guide rail, wall-attached guide bases, anti-falling devices and the like, each anti-falling device comprises an anti-falling wheel, an elastic device and a pair of pawls distributed on the two sides of the corresponding anti-falling wheel, wherein each elastic device is connected between the corresponding pair of pawls and maintains the distance between the pair of pawls by providing pre-tightening force, and ratchet wheel teeth are arranged on the side surface of each anti-falling wheel; andwhen the guide rail ascends, the anti-falling wheels rotate clockwise, and when the ratchet wheel teeth collide with the pawls, the pre-tightening force is overcome by inclined face mutual thrust sothat each pair of pawls are pulled open to enable the ratchet wheel teeth to rotationally pass; and when the guide rail descends, the anti-falling wheels rotate anticlockwise, the ratchet wheel teethmeshes with the pawls when colliding with the pawls to prevent the ratchet wheel teeth from rotationally passing, so that the guide rail is braked, and the guide rail is prevented from descending. Theframe is simple in structure, low in machining cost, convenient to maintain and high in reliability and has an automatic positioning function.
本发明公开了一种棘轮定位防坠的爬架，包括导轨、附墙导座、防坠装置等，所述防坠装置包括防坠轮、弹性装置和分布在所述防坠轮两侧的一对棘爪，所述弹性装置连接于所述一对棘爪之间并通过提供预紧力维持所述一对棘爪之间的距离，所述防坠轮的侧面具有棘轮齿；导轨上升时所述防坠轮顺时针旋转，所述棘轮齿和棘爪碰撞时通过斜面互推力克服所述预紧力将所述一对棘爪相互拉开以便所述棘轮齿旋转通过；导轨下坠时所述防坠轮逆时针旋转，所述棘轮齿和棘爪碰撞时啮合以阻止所述棘轮齿旋转通过，从而对导轨进行制动，防止导轨下坠，本发明结构简单，加工成本低，维护方便，可靠性高，具有自动定位的功能。
