The invention relates to the technical field of pulleys, in particular to a safe lifting clutch which comprises a movable side plate, bearings transversely and linearly arranged are installed on the three side faces of the movable side plate in a penetrating mode, and a one-way pulley and a movable pulley are inserted between inner rings of every two adjacent bearings in a close fit mode. A rope brake wheel is inserted into an inner ring of one bearing in a close fit mode, a pawl cam is connected to the side face of the movable side plate, and the surface of the pawl cam makes contact with the surface of the one-way pulley. According to the scheme, the one-way pulley and the movable pulley are arranged, the rope can be sequentially wound on the surfaces of the one-way pulley and the movable pulley by 360 degrees, the friction force of contact between the rope and the pulley is increased, and then the stability and safety of connection between the rope and the pulley are improved.
本发明涉及滑轮技术领域,尤其是一种安全升降离合器,包括活动侧板,所述活动侧板的三个侧面均贯穿安装有横向线性排列的轴承,相邻两个所述轴承的内圈之间分别紧配插接有单向滑轮和动滑轮,其中一个所述轴承的内圈中紧配插接有绳索制动轮,所述活动侧板的侧面连接有棘爪凸轮,所述棘爪凸轮的表面与单向滑轮的表面接触。本方案中通过设置单向滑轮和动滑轮,绳索可360度依次绕接在单向滑轮和动滑轮的表面,增加了绳索与滑轮之间接触的摩擦力,进而提升了绳索和滑轮之间连接的稳定性和安全性。
