The invention belongs to the technical field of pipeline construction, and provides a lifting device for fire-fighting ventilation pipeline construction.The lifting device comprises a supporting frame, a base, a clamping block, a first push block, a first spring, an electromagnetic switch, a second spring and a second push block, a brake unit is arranged around a lead screw, and when power is accidentally cut off, the second spring in the stretching state pulls the second push block to slide downwards; the clamping blocks are subjected to thrust transmitted by the first spring in the contraction state, so that the clamping block heads are tightly attached to the outer wall of the lead screw, and the effect of emergency braking of the lead screw for supporting the pipeline is achieved. The multiple supporting arms are arranged on the side face of the sliding block, and the tail ends of the supporting arms are arranged to be in a bent shape, so that the reinforcing effect of supporting and fixing the pipeline is achieved; the lifting device for fire-fighting ventilation pipeline construction solves the problems that an existing lifting device for fire-fighting ventilation pipeline construction often causes the ventilation pipeline to fall from a high place to be damaged due to misoperation or sudden power failure and the like, and the safety in the using process is reduced, the safety in the using process of the device is improved, and the using steps of the device are simplified.

    本发明属于管道施工技术领域,提供一种消防通风管道施工用提升装置,包括支撑架、底座、夹块、推块一、弹簧一、电磁开关、弹簧二和推块二,通过在丝杆的周围设置制动单元,当意外断电时,伸长状态的弹簧二拉动推块二向下滑动,夹块受到处于收缩状态的弹簧一传递的推力,使得夹块头紧贴着丝杆的外壁,实现对支撑管道的丝杆进行紧急制动的效果;通过在滑块的侧面设置多个支撑臂以及将支撑臂的末端设置为弯曲形状,实现对管道支撑和固定的强化效果;解决了现有的消防通风管道施工用提升装置常因为操作不当或突然断电等原因,导致通风管道从高处落下摔坏,降低了使用过程安全性的问题,提高了装置使用过程的安全性,简化了装置的使用步骤。
