The invention relates to the technical field of machinery, and discloses a novel movable pulley block device which comprises a fixing frame, two first pulleys are arranged at the bottom end of the fixing frame, two second pulleys are arranged on one side of the fixing frame, a limiting structure for fixing the second pulleys is arranged in the fixing frame, and a protective shell is fixedly installed at the top end of the fixing frame. The fixing structures are symmetrically arranged in the protective shell, the clamping structures are arranged on one sides of the fixing structures, by arranging the limiting structures, the second pulley can be effectively and rapidly installed, the first pulley and the second pulley can rotate on the two planes at the same time, and a steel wire rope of the crane can be wound at different angles; a worker installs two second pulleys, inserts a fixing block on a support into a fixing cylinder and aligns a fixing pile on the fixing block to a clamping groove, the length of a positioning column in a containing cavity is shortened, a spring deforms to generate elastic potential energy, after the support is rotated, the fixing pile moves along the clamping groove, and finally the fixing cylinder and the support are clamped.

    本发明涉及机械技术领域,且公开了一种新型动滑轮组装置,包括固定架,固定架的底端设置有两个滑轮一,固定架的一侧设置有两个滑轮二,固定架的内部设置有固定滑轮二的限位结构,固定架的顶端固定安装有防护壳,防护壳的内部对称设置有固定结构,固定结构的一侧设置有夹持结构,通过设置限位结构,可以有效快速安装滑轮二,使滑轮一和滑轮二可以同时在两个平面旋转,起重机的钢丝绳就可以实现不同角度的缠绕,使用时,工作人员安装两个滑轮二,将支架上的固定块插入固定圆筒,将固定块上的固定桩对准卡槽,容纳腔内部的定位柱缩短长度,并且弹簧发生形变产生弹性势能,转动支架后,固定桩沿着卡槽移动,最终使固定圆筒和支架形成卡接。
