Climbing frame with ratchet wheel automatic positioning guide seat
The invention discloses a climbing frame with a ratchet wheel automatic positioning guide seat. The climbing frame with the ratchet wheel automatic positioning guide seat comprises a guide rail, wall-attached guide seats and anti-falling devices; the anti-falling devices comprise positioning anti-falling wheels, elastic pre-tightening devices and pawls; ratchet teeth are arranged at the side partsof the positioning anti-falling wheels; and pawl springs for providing an acting force for hindering rotation of the pawls when the pawls rotate clockwise are further arranged on the wall-attached guide seats. In the anticlockwise rotating process of the positioning anti-falling wheels due to ascending of the guide rail, when the ratchet teeth collide with the pawls, the pre-tightening forces ofthe elastic pre-tightening devices are overcome through mutual thrust of inclined planes so as to pull open the pawls relative to the ratchet teeth, so that the ratchet teeth can rotationally pass through; and in the process that the positioning anti-falling wheels rotate clockwise due to descending of the guide rail, the ratchet teeth and the pawls are meshed and rotate clockwise together, part or all of the pawl springs provide acting force to prevent the corresponding pawls from continuously rotating, and finally, the corresponding positioning anti-falling wheels are stressed in an up-and-down cooperation mode to support the guide rail. The climbing frame with the ratchet wheel automatic positioning guide seat has the advantages that the structure is simple, maintenance is convenient, reliability is high, and an up-and-down cooperative stress self-positioning function is achieved.
本发明公开了一种棘轮自动定位导座的爬架，包括导轨、附墙导座、防坠装置，防坠装置包括定位防坠轮、弹性预紧装置和棘爪，定位防坠轮的侧部具有棘轮齿，附墙导座上还设置有在棘爪顺时针旋转时提供阻碍其旋转的作用力的棘爪弹簧；定位防坠轮因导轨上升而逆时针旋转过程中，棘轮齿和棘爪碰撞时通过斜面互推力克服弹性预紧装置的预紧力将所述棘爪相对棘轮齿拉开以便棘轮齿旋转通过；定位防坠轮因导轨下降而顺时针旋转过程中，棘轮齿和棘爪啮合并一起顺时针旋转，部分或者全部的棘爪弹簧提供作用力以阻碍对应的棘爪继续旋转，最终使对应的定位防坠轮上下协同受力支撑导轨，本发明结构简单，维护方便，可靠性高，具有上下协同受力自定位的功能。
