The invention discloses an anti-falling suspension device which comprises a working box, a moving unit used for pulling back and decelerating, a rope locking unit and a rotating unit used for detecting falling. A suspension box is arranged at the lower end of the working box, a hoist is arranged on one side in the working box, a traction rope is arranged on the hoist, and a rotating unit is arranged on one side in the working box; the moving unit comprises shaft grooves symmetrically formed in the front end and the rear end of the interior of the working box, wheel shafts are slidably connected into the shaft grooves, and cone pulleys used for reducing and pulling back are rotatably and slidably connected to the wheel shafts; at the moment of falling, the cone pulley moves upwards and backwards at the same time, the diameter wound by the traction rope is increased, a heavy object is pulled back, meanwhile, the rubber hemisphere on the T-shaped cylinder is tightly attached to the rubber hemisphere in the annular groove, friction force is increased, the falling acceleration of the traction rope is reduced, and due to the eccentric effect, the cone block rotates to further pull the traction rope back, and under the cooperation with the fixed block, the traction rope is fixed. The staggered traction rope is fixed, and the anti-falling effect is better and more stable.

    本发明公开了一种防坠落悬挂装置,包括工作箱、用于回拉减速的移动单元、锁绳单元和用于检测下坠的旋转单元;工作箱下端设有悬挂箱,工作箱的内部一侧设有葫芦吊,葫芦吊上设有牵引绳,工作箱的内部一侧设有旋转单元;移动单元包含对称开设在工作箱内部前后两端的轴槽,轴槽内滑动连接有轮轴,轮轴上转动且滑动连接有用于变径回拉的锥轮;本发明在发生坠落瞬间,锥轮上移同时后移,增大牵引绳绕过的直径,回拉重物,同时T型筒上的橡胶半球紧贴环槽内的橡胶半球,增大摩擦力,减缓牵引绳下坠的加速度,由于偏心的作用,锥块转动进一步回拉牵引绳,在与定块配合下,对错位的牵引绳进行固定,防坠落的效果更好更稳定。
