The invention discloses a hoisting and lifting device used for a steel structure net rack rod piece. A first motor is installed on a base, an output end of the first motor is connected with a speed reducer, two ends of an output shaft of the speed reducer are connected with speed regulating wheels and winding discs respectively, a speed regulating frame used for controlling the rotating speeds of the speed regulating wheels is further arranged on the speed reducers, and cables of the winding discs are wound around movable pulleys on a rack to be connected with lifting frames. Triangular blocks of the lifting frames are inserted into a steel structure net rack rod piece, third motors drive lead screws to rotate, the lead screws drive nut bases to move upwards, each nut base drives corresponding sliding blocks at two sides to move oppositely on a corresponding guide rod through corresponding connecting plates, thus each two triangular blocks move oppositely, corresponding positioning rods of each two triangular blocks are mutually crossed and locked, and the speed reducer is driven by the first motor to drive the two winding discs to synchronously wind, so that lifting of the steel structure net rack rod piece is more stable, and rollover, of the steel structure net rack rod piece, due to uneven stress in the lifting process is effectively avoided.

    本发明公开了一种用于钢结构网架杆件的吊装抬升装置,底座上安装有电机一,电机一的输出端连接有减速器,减速器的输出轴两端分别连接有调速轮和收卷盘,减速器上还设置有用于调速轮进行转速控制的调速架,收卷盘的缆绳绕过机架上的动滑轮连接有起吊架,将起吊架的三角形块插入钢结构网架杆件内,通过电机三驱动丝杆转动,通过丝杆驱动丝母座向上移动,丝母座通过连接板带动两侧的滑动块在导向杆上相向移动,使两个三角形块相向移动,使两个三角形块的定位杆相互交叉锁紧,通过电机一驱动减速器带动两个收卷盘同步收卷,使钢结构网架杆件的提升更加稳定,有限避免钢结构网架杆件在提升过程中由于受力不均发生侧翻。
