The invention relates to the field of pulleys, in particular to a combined pulley set achieving moving and fixed pulley conversion. The combined pulley set comprises a pulley carrier. A bearing frameis arranged in the middle of the outer surface of the front end of the pulley carrier. A first through hole is formed in the middle of the upper end of the pulley carrier in a penetrating manner. A load-bearing hook is arranged in the first through hole. Second through holes are formed in the front end of the pulley carrier and the front end of the load-bearing hook in a penetrating manner. A round hole is formed in the front end of the bearing frame in a penetrating manner. Bearing blocks are arranged on the inner side of the round hole and the inner side of the bearing frame. A pulling ringis fixedly connected to the front end of each bearing block. A reset spring is arranged on the inner side of the bearing frame. A limiting clamp column is arranged in each second through hole. The middle of the rear end of the pulley carrier is fixedly connected with a connecting block. According to the combined pulley set achieving moving and fixed pulley conversion, a moving pulley and a fixed pulley can be converted conveniently, the load-bearing hook can be replaced conveniently, and better application prospects are brought.

    本发明涉及滑轮领域,特别涉及一种动、定滑轮转换的组合式滑轮组,包括滑轮架,所述滑轮架的前端外表面中部设置有承载框,所述滑轮架的上端中部贯穿设置有一号通孔,所述一号通孔的内部设置有承重挂钩,所述滑轮架的前端与承重挂钩的前端均贯穿设置有二号通孔,所述承载框的前端贯穿设置有圆形孔,所述圆形孔的内侧与承载框的内侧均设置有承载块,所述承载块的前端固连有拉动环,所述承载框的内侧设置有复位弹簧,所述二号通孔的内部设置有限制卡柱,所述滑轮架的后端中部固连有连接块。本发明所述的一种动、定滑轮转换的组合式滑轮组,能够便于对动、定滑轮进行转换,且能够便于对承重挂钩进行更换,带来更好的使用前景。
