Climbing frame with automatic ratchet wheel positioning and cooperative stress centrifugal anti-falling guide seat
The invention discloses a climbing frame with an automatic ratchet wheel positioning and cooperative stress centrifugal anti-falling guide seat. The climbing frame with the automatic ratchet wheel positioning and cooperative stress centrifugal anti-falling guide seat comprises a guide rail, a plurality of wall-attached guide seats and anti-falling devices; the anti-falling devices comprise positioning anti-falling wheels, elastic pre-tightening devices and pawls; and ratchet teeth are arranged at the side parts of the positioning anti-falling wheels. The elastic pre-tightening devices are adjusted to be in a first pre-tightening state when the guide rail needs to ascend; due to the distances from the pawls to the ratchet teeth, the ratchet teeth are enabled to be meshed with the pawls; inthe anticlockwise rotating process of the positioning anti-falling wheels due to ascending of the guide rail, the pawls are pulled open relative to the ratchet teeth through mutual thrust of inclinedplanes when the ratchet teeth and the pawls collide, so that the ratchet teeth can rotationally pass through; and in the clockwise rotating process of the positioning anti-falling wheels due to descending of the guide rail, the ratchet teeth are meshed with the pawls to prevent the ratchet teeth from rotationally passing through; and when the guide rail needs to descend, the elastic pre-tighteningdevices are adjusted to be in a second pre-tightening state, and the pawls are separated from the ratchet teeth due to the distances between the pawl and the ratchet teeth. The climbing frame with the automatic ratchet wheel positioning and cooperative stress centrifugal anti-falling guide seat has the advantages that the structure is simple, the automatic positioning function is achieved, and the climbing frame can move up and down.
本发明公开了一种自动棘轮定位协同受力离心防坠导座的爬架，包括导轨、多个附墙导座、防坠装置，防坠装置包括定位防坠轮、弹性预紧装置、棘爪，定位防坠轮的侧部具有棘轮齿，导轨需要上升时弹性预紧装置被调节到第一预紧状态，棘爪相对棘轮齿的距离使得棘轮齿和棘爪啮合，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将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，棘轮齿和棘爪啮合以阻止棘轮齿旋转通过；导轨需要下降时弹性预紧装置被调节到所述第二预紧状态，棘爪相对棘轮齿的距离使得所述棘爪与所述棘轮齿的脱离，本发明结构简单，具有自动定位的功能，爬架可以上下移动。
