The invention relates to the technical field of construction hoists, in particular to a safety type construction hoist which comprises a guide rail frame, a cage, a transmission device and an anti-impact assembly. The anti-pinch device has the advantages that the anti-pinch device can effectively prevent the feeding door from pinching workers below the door, normal operation of the anti-pinch device cannot be affected by power failure due to the fact that the anti-pinch device does not depend on an electrical structure, the failure rate is low, and the safety coefficient is high. The anti-impact assembly has a buffering effect, rigid collision is avoided, and personnel driving the trolley (operating the trolley) are prevented from being injured; when impact is large and the transverse rod continues to move outwards, the second limiting part limits the transverse rod, the transverse rod is limited from moving outwards, a vehicle (trolley) in the elevator is prevented from rushing out of the feeding door, and the safety coefficient of the feeding door is greatly improved through the two safety measures of arranging the buffering piece and the second limiting part.

    本发明涉及施工升降机技术领域,特别是涉及一种安全型施工升降机,包括导轨架、吊笼、传动装置和防冲组件。有益效果:防夹装置能有效防止进料门夹伤门下的工作人员,由于不依赖电气结构,停电不会影响防夹装置的正常运作,故障率低,安全系数高。防冲组件起到缓冲的效果,避免了刚性碰撞,防止驾驶车辆(操作斗车)的人员受伤;当冲击较大,横杆继续向外移动时,第二限位部对横杆进行限位,限制横杆外移,防止升降机内的车辆(斗车)冲出进料门,通过设置缓冲件和第二限位部两道安全措施,大大提升了进料门的安全系数。
