The invention provides a pulley mechanism based on a hoisting half-and-half track. The pulley mechanism comprises a bearing assembly, a pulley main body, a spherical fixing plate and a ball head connecting assembly, the pulley main body is hung below the bearing assembly through a countersunk pin column; spherical fixing plates are installed on the two sides of the bottom of the tackle body to form a semi-closed spherical cavity mechanism, a ball head bolt of the ball head connecting assembly and the cavity mechanism form a rotatable device, and external power drives a hanging piece connected with the ball head connecting assembly to operate through the tackle body.

    本发明提供一种基于吊装对半式轨道用的轮滑车机构,包括:轴承组件、滑车主体、球面固定板、球头连接组件;滑车主体通过沉头销柱悬挂在轴承组件下方;滑车主体的底部两侧安装球面固定板,形成半封闭球形腔体机构,球头连接组件的球头栓与腔体机构形成可转动装置,外部动力通过滑车主体带动与球头连接组件相连接的挂件运行。
