The invention discloses a hoisted object falling preventing device for a crane. The hoisted object falling preventing device comprises a fixing base, a fixing structure, a rotating rod, a binding belt, a first gear, a first screw rod, a second screw rod, a second gear, a sliding block and a connecting structure. The hoisted object falling preventing device has the beneficial effects that the firstgear is fixedly mounted on the rotating rod and is engaged with the second gear, the first screw is rotatably mounted on the inner wall of the fixing base, the first screw rod penetrates through andis in threaded connection with the sliding block, and the sliding block is in sliding connection with the fixing base, the binding belt and the sliding block pass by a tree to be connected to the fixing base, the rotating rod is rotated, the rotating rod can drive the first gear to rotate, the first gear can drive the second gear and the first screw rod to rotate, the first screw rod is in threaded connection with the sliding block, and the sliding block is in sliding connection with the inner wall of the fixing base, so that the sliding block is driven to slide on the inner wall of the fixingbase, the sliding block and the binding belt move towards the top of the fixing base together, and the tree can be firmly pressed and fixed to the bottom of the fixing base through the binding belt.
本发明公开了一种用于吊车的吊物防掉落装置,包括固定座、固定结构、转动杆、绑带、第一齿轮、第一螺杆、第二螺杆、第二齿轮、滑块和连接结构。本发明的有益效果是:转动杆上固定安装有第一齿轮,第一齿轮与第二齿轮啮合,第一螺杆转动安装有固定座的内壁,第一螺杆贯穿并螺纹连接有滑块,滑块与固定座滑动连接,因而将绑带和滑块穿过树木连接至固定座,并转动转动杆,转动杆会带动第一齿轮转动,第一齿轮会带动第二齿轮和第一螺杆转动,第一螺杆上螺纹连接有滑块,滑块和固定座内壁之间滑动连接,因而会带动滑块在固定座内壁滑动,从而滑块和绑带一起向着固定座顶部运动,绑带会将树木牢牢地压紧并固定在固定座的底部。
