The invention discloses a safety protection device for a housing construction elevator. The safety protection device comprises a first guide rail, a first sliding block, a speed limiting locking device, a second guide rail, a second sliding block, an elastic cushion and a buffering device. When the lift car stalls and moves down quickly, a first gear can drive a transmission shaft to rotate at a high speed, and the transmission shaft rotates at a high speed to enable a speed limiting block to get rid of tension of a tension spring to move outwards to clamp the inner wall of a sleeve body for speed reduction, so that it can be ensured that the lift car can only move at a safe speed, and the real-time protection effect of an elevator is achieved; when heavy materials or equipment are transported, the lift car still stalls and moves downwards quickly after speed reduction, the sleeve body gets rid of frictional resistance between the overload clamping block and the overload clamping groove and rotates, and the sleeve body rotates to drive the screw rod to rotate through the second gear. And through rotation of the screw rod, the telescopic block extends out to enable the brake block to clamp the first guide rail and the second guide rail for locking, so that the car can be completely prevented from moving, and maintenance personnel can conveniently maintain the elevator.

    本发明公开了一种房建施工电梯安全防护装置,包括导轨一、滑块一、限速锁紧装置、导轨二、滑块二、弹性垫和缓冲装置;本发明中当轿厢出现失速加快下移时齿轮一会带动传动轴高速旋转,而传动轴高速旋转则会使限速块摆脱拉簧拉力外移卡紧套体内壁进行减速,从而能够确保轿厢只能在安全速度移动,也就满足了电梯实时防护的效果;本发明中当运输较重的材料或设备后轿厢减速后依然失速加快下移时会使套体摆脱过载卡块与过载卡槽的摩擦阻力发生旋转,而套体的旋转则通过齿轮二带动螺杆旋转,而螺杆的旋转则使伸缩块伸出使刹车块卡住导轨一和导轨二进行锁紧,也就能够完全阻止轿厢发生移动,进而便于维修人员对电梯进行维修。
