Telescopic ladder device
The invention discloses a telescopic ladder device. A movable support is installed at the bottom of a first-stage ladder, can rotate around a bottom rotating shaft by 0-270 degrees, and can be fixed when rotated to a required position in use, so that the surface contact between the bottom and a supporting plane is realized; a second-stage ladder is installed inside the first-stage ladder, a handle of the second-stage ladder is a movable handle, the movable handle can be folded when the second-stage ladder is folded, a ratchet wheel clamping device is opened, and then the second-stage ladder can be folded; the second-stage ladder is lifted by adopting a pulley block, a pulley integrated with a ratchet wheel is rotated clockwise, and a rope is folded, so that the purpose of lifting the second-stage ladder can be achieved; and small pulleys are installed on the left side, the right side, the front side and the back side of the second-stage ladder, so that the friction between the second-stage ladder and the first-stage ladder is reduced, and the lifting resistance is reduced. The telescopic ladder device has important significance for realizing climbing operation.
本发明公开了一种伸缩梯装置，本发明的活动支撑安装在第一级梯底部，可绕底部旋转轴0‑270°旋转，并且在使用时转到需求位置可进行固定，实现底部与支撑平面的面接触；第二级梯安装在第一级梯内部，且第二级梯把手为活动把手，收缩时可将活动把手收起，打开棘轮卡死装置，即可收缩第二级梯；第二级梯的升起采用滑轮组，顺时针旋转与棘轮一体的滑轮，收缩绳索便可达到升起第二级梯的目的；第二级梯的左右正反两侧均装有小滑轮，减少与第一级梯的摩擦，降低上升的阻力。对于实现登高作业重要意义。
