The invention provides a pulley structure for avoiding rope winding. The pulley structure comprises a support body, a fixed pulley arranged at the lower end of the support body, a movable pulley arranged at the lower end of the fixed pulley, and a lifting hook arranged at the lower end of the movable pulley. The fixed pulley is connected with the movable pulley through a pulley rope, and the lifting hook is arranged on a movable pulley seat. The pulley structure further comprises an anti-winding mechanism for preventing the rope from winding, the top end of the anti-winding mechanism is arranged on the fixed pulley seat, and the bottom end of the anti-winding mechanism is arranged on the movable pulley seat. According to the pulley structure for avoiding rope winding, when the pulley is used for hoisting a heavy object, the problem that the pulley rope is frequently rotated and twisted is solved, and damage to an insulated wire is avoided.
本发明提供了一种用于避免绳索缠绕的滑轮结构,包括支撑体、设置在支撑体下端的定滑轮、设置在定滑轮下端的动滑轮、设置在动滑轮下端的吊钩,定滑轮通过滑轮绳与动滑轮连接,吊钩设置在动滑轮座上,还包括用于避免绳索缠绕的防缠绕机构,防缠绕机构顶端设置在定滑轮座上,防缠绕机构底端设置在动滑轮座上。本发明提供的用于避免绳索缠绕的滑轮结构,使得滑轮在起吊重物时,避免了滑轮绳经常旋转拧动的问题,避免了绝缘线的损坏。
