The construction safety lifter comprises a lifting frame, a lift car is arranged on one side of the lifting frame in a liftable mode, two guide rails allowing the lift car to slide are fixed to one side of the lifting frame, two top plates corresponding to the guide rails are fixed to the top end of the lift car, and two clamping plates for clamping the guide rails are arranged on one sides of the top plates in a slidable mode; according to the construction safety elevator, when the elevator car breaks down and freely falls, a person turns on a telescopic rod switch in the elevator car, an electric telescopic rod can drive a second sliding block to move, the second sliding block drives a pull plate to move through a connecting plate, the pull plate drives a pull rod to move, the pull rod drives a first sliding block to move, and the first sliding block drives a clamping plate to move; meanwhile, the clamping plates drive the friction plates to abut against the guide rails, the friction force between the clamping plates and the guide rails is increased, and therefore the lift car can be conveniently clamped and decelerated until the lift car stops, safety accidents caused by falling of the lift car are avoided, and the use safety of the lift is improved.
本申请公开了一种施工安全升降机,其包括升降架,升降架的一侧可升降的设有轿厢,升降架的一侧固定有两个供轿厢滑动的导轨,轿厢的顶端固定有两个与导轨相对应的顶板,顶板的一侧可滑动的设有两个对导轨夹持的夹板;该施工安全升降机,当轿厢发生故障而自由下落时,人员将轿厢内的伸缩杆开关打开,电动伸缩杆即可带动第二滑块的运动,第二滑块通过连板带动拉板的运动,拉板带动拉杆的运动,拉杆即带动第一滑块的运动,第一滑块带动夹板的运动,使夹板对导轨夹紧,同时夹板带动摩擦板与导轨抵触,增大夹板与导轨间的摩擦力,从而方便对轿厢夹紧减速至停止不动,避免轿厢掉落而发生安全事故,提高了升降机使用的安全性。
