The invention discloses a safety fire ladder, and relates to the technical field of fire ladders, the safety fire ladder comprises a fire ladder main support, a kick pedal support and a stay bar, the fire ladder main support comprises a main fixing support, a first ladder stand frame and a second ladder stand frame, and the side end of the first ladder stand frame is fixedly provided with an anti-clamping support guide mechanism; the second ladder stand frame is sleeved with a clamping groove of the anti-clamping type supporting and guiding mechanism, a supporting clamping groove base can limit the second ladder stand frame, the second ladder stand frame does not deviate when moving upwards in the supporting clamping groove base, friction between the outer end of the second ladder stand frame and the inner side of the first ladder stand frame does not occur, and therefore the ladder stand frame can stably work. Through the anti-clamping pulleys, the second ladder stand frame can move upwards more smoothly, and the phenomenon of clamping is avoided; the anti-winding sleeve seat can play a limiting role, so that the part, passing through the limiting type anti-winding assembly at the side end of each kick pedal support, of the pull rope and the transmission rope can slide in a proper range, and the phenomenon that the pull rope and the transmission rope are wound is effectively avoided.
本发明公开一种安全消防梯，涉及消防梯技术领域，包括消防梯主支架、踢蹬支架和撑杆，消防梯主支架包括主固定支架、第一爬梯架和第二爬梯架，第一爬梯架侧端固定装设有防卡式支撑导向机构，第二爬梯架套接于防卡式支撑导向机构卡槽内，支撑卡槽座能够对第二爬梯架起到限位的作用，通过将第二爬梯架在支撑卡槽座内向上运动时不会产生偏移，使得第二爬梯架外端与第一爬梯架内侧不会产生摩擦，通过防卡滑轮能够使得第二爬梯架向上运动时会更加的顺畅，不会出现卡顿的现象；防缠绕套座能够起到限位的作用，使得拉绳及传动绳经过每个踢蹬支架侧端的限位式防缠绕组件的部分能够在适当的范围内滑动，有效避免拉绳及传动绳发生缠绕的现象。
