The invention discloses a double-pulley transition guide mechanism and a lifting device. The double-pulley transition guide mechanism comprises a connecting frame, a first guide assembly and a second guide assembly. The connecting frame is installed between the main cargo boom and the auxiliary boom, the first guide assembly is installed on the connecting frame, and the second guide assembly is installed on the auxiliary boom; when the fly jib is in a working state, the first guide assembly and the second guide assembly are vertical relative to the fly jib and are assembled in the same direction; when the auxiliary arm is in a folded state, the first guide assembly and the second guide assembly are transversely assembled in the direction perpendicular to the axis of the auxiliary arm, and the assembling directions are opposite. The first guide assembly and the second guide assembly are small in size, the risk that a steel wire rope interferes with the main cargo boom or the auxiliary boom in the working state of the auxiliary boom is reduced, and the lightweight level can be improved easily; the first guide assembly and the second guide assembly are transversely assembled in opposite directions when the auxiliary arm is in the folded state, the occupied space is reduced, the rope winding function is achieved, and operation convenience is improved.
本发明公开了一种双滑轮过渡导向机构及起重装置,包括连接架、第一导向组件和第二导向组件;所述连接架安装于主起重臂和副臂之间,所述第一导向组件安装于连接架,所述第二导向组件安装于副臂;所述副臂呈工作状态时,所述第一导向组件和第二导向组件相对副臂竖直且同向装配;所述副臂呈折叠状态时,所述第一导向组件和第二导向组件在垂直于副臂轴线的方向上横向装配且装配方向相反。本发明的第一导向组件和第二导向组件尺寸小,减少了副臂工作状态下钢丝绳与主起重臂或副臂干涉的风险,且有利于提高轻量化水平;第一导向组件和第二导向组件在副臂呈折叠状态时横向装配且装配方向相反,既减少了占用空间,又兼具绕绳功能,提高了操作便捷性。
