The invention relates to the technical field of hoisting devices, in particular to a hoisting device for mounting a steel fireproof door, which comprises a suspension plate, a linkage mechanism, a direction adjusting mechanism, a rotating mechanism, a matching mechanism, a tensioning mechanism and a positioning mechanism. The two winding rollers rotate to release the drawstring at the same time, the two winding rollers wind the drawstring at the same time and force the suspension plate to ascend, suspension can be completed, the roller shutter door can be forced to be close to the installation position through tightening of the drawstring and sliding of the moving box, and the roller shutter door can be driven to be close to the installation position through simultaneous rotation of the direction adjusting mechanism and the transmission mechanism. The roller shutter door can be forced to rotate through the one-way tightening effect of the drawstring, so that a fixing screw hole of the roller shutter door can be conveniently adjusted, overall work is facilitated, the working efficiency is improved, the allowance, located on the surfaces of the two winding rollers, of the drawstring can be adjusted through simultaneous rotation of the linkage mechanism and the matching mechanism, and the practicability is high. And it is guaranteed that when the drawstring works again, the rolling length for smooth work can be reserved, and normal work is guaranteed.

    本发明涉及吊运装置技术领域,具体涉及一种钢质防火门安装用吊运装置,包括悬吊板、联动机构、调向机构、转动机构、配合机构、张紧机构以及定位机构。本发明通过两个卷辊转动同时释放拉带,并通过两个卷辊同时收卷拉带并迫使悬吊板上升,即可完成悬吊,并通过拉带的收紧及移动盒的滑动,可迫使卷帘门靠近安装部位,通过调向机构及传动机构同时转动,可以通过拉带的单向收紧效果迫使卷帘门进行转动,以此可方便对卷帘门的固定螺孔进行调整,方便整体的工作并提高工作效率,通过联动机构及配合机构的同时转动,可以对拉带位于两个卷辊表面的余量进行调整,保证拉带可以在再次工作时,可以存留有顺利工作的收卷长度,保证工作的正常进行。
