The invention discloses a vertical shaft air pipe lifting tool and a lifting device thereof, and belongs to the technical field of building equipment.The lifting tool comprises a lifting frame connected to the upper surface of an air pipe flange of a vertical shaft air pipe through bolts, and the lifting frame is provided with a lifting component hooked by a lifting hook; the hoisting component is provided with a hoisting point capable of guaranteeing that the vertical projection of the hoisting hook coincides with the gravity center of the hoisting frame in the hoisting process. The lifting device comprises a rolling device with a lifting hook and a lifting tool, the rolling device is fixed in the vertical shaft, and the lifting hook is located over the lifting point. After the lifting frame provided with the lifting component is in bolted connection with an air pipe flange on the vertical shaft air pipe, lifting can be carried out by hooking a lifting point of the lifting component through the lifting hook, the vertical shaft air pipe in the vertical shaft is installed, and force can be evenly distributed on the air pipe flange in the mode that the lifting frame is connected with the air pipe flange. And the problem of easy deformation caused by the traditional mode of hooping the vertical shaft air pipe body is avoided.
本发明公开了一种竖井风管提升工装及其提升装置,属于建筑设备技术领域,提升工装包括螺栓连接在竖井风管的风管法兰上表面的提升框架,提升框架上设有供提升吊钩勾住的吊装构件,吊装构件上设有能够保证提升吊钩的竖向投影在提升过程中与提升框架的重心重合的吊装点;提升装置包括自带提升吊钩的卷升设备和提升工装,卷升设备固定在竖井内,提升吊钩位于吊装点的正上方。设有吊装构件的提升框架和竖井风管上自带的风管法兰进行螺栓连接后,通过使提升吊钩勾住吊装构件的吊装点便可进行提升,实现竖井内竖井风管的安装,利用提升框架和风管法兰连接的方式,可使力均匀分布在风管法兰上,避免了传统箍紧竖井风管本体的方式所带来的易变形的问题。
