The invention discloses an elevator anti-falling safety device for a building. The elevator anti-falling safety device for the building comprises a transmission device, a first speed reduction device, a second speed reduction device and a damping device, all of which are installed on a rack. The damping device on the elevator anti-falling safety device is connected with the lower portion of an elevator, when the elevator fails and drops, a mechanical set in the transmission device operates to drive a first speed reduction piece on the first speed reduction device to be supported outwards to form friction with an elevator bin side plate for first speed reduction, and a mechanical set in the second speed reduction device operates to drive a second speed reduction piece to be attached to a speed reduction block to form friction for second speed reduction; and when the elevator drops to the ground, a damping spring on the damping device is pressed down to release residual force so as to ensure the safety of people in the elevator.
本发明公开了一种建筑用电梯防坠落安全装置,包括传动装置、第一减速装置、第二减速装置和减震装置安装在机架上,装置上的减震装置与电梯下方连接,当电梯出现故障坠落时,传动装置内部机械组运转带动第一减速装置上的第一减速片向外支撑与电梯仓侧板形成摩擦进行第一次减速,第二减速装置内部机械组运转带动第二减速片与减速块贴合形成摩擦进行第二次减速,当电梯坠落至地面时,减震装置上的减震弹簧下压卸下余力以保证电梯内人员安全。
