The invention relates to the technical field of hoisting equipment, in particular to a stable hoisting device for loading and unloading of a building tower crane, which comprises a group of support frame, a clamping mechanism comprises two groups of chain wheels mounted at the top and the bottom of the support frame, the two chain wheels at the top of the support frame are connected through a rotating shaft, and a chain is arranged outside the chain wheels. The chain is movably connected with a group of clamping blocks; the transmission mechanism comprises a worm wheel fixedly installed outside the rotating shaft, a first connecting plate and a second connecting plate are arranged on the two sides of the worm wheel respectively and connected through a worm, a movable plate is rotationally connected to one side of the first connecting plate, and a spring is fixedly connected to the bottom of the second connecting plate. A fastening mechanism used for fixing the second connecting plate is arranged on one side of the second connecting plate. A clamping mechanism is matched with a transmission mechanism, and a pipe is pressed to a movable plate, so that a worm is separated from a worm gear, the pipe moves downwards under the support of a first connecting piece, when the pipe is separated from the movable plate, the first connecting plate is reset, two adjacent clamping blocks completely clamp the pipe, and the stability of the pipe during hoisting is guaranteed; and friction between the clamping blocks and the pipe is increased.
本发明涉及吊装设备技术领域,具体的说是一种建筑塔吊装卸用稳固吊装装置,包括一组支撑架,夹持机构包括安装在支撑架顶部和底部的两组链轮,支撑架顶部的两个链轮之间有转轴连接,链轮外设置有链条,链条上活动连接有一组夹持块;传动机构包括固定安装在转轴外部的蜗轮,蜗轮两侧分别设置有第一连接板和第二连接板,第一连接板与第二连接板之间有蜗杆连接,第一连接板一侧转动连接有活动板,第二连接板底部固定连接有弹簧,第二连接板一侧设置有用于固定第二连接板的紧固机构。通过夹持机构配合传动机构,管材按压到活动板,从而使得蜗杆与蜗轮分离,管材在第一连接件的支撑下下移,管材与活动板分离时,第一连接板复位,两个相邻夹持块将管材完全夹持住,保证在起吊时管材的稳定性,增大夹持块与管材之间的摩擦。
