The invention relates to the technical field of engineering machinery, and discloses a pulley rope winding structure of a trolley and a lifting hook and a tower crane. The pulley rope winding structure comprises a trolley pulley module, a lifting hook pulley module, a switching pulley module and a steel wire rope, the trolley pulley module comprises a first pulley, a second pulley and a third pulley which are arranged on the trolley and distributed in the linear direction, and the included angle between the connecting line direction and the length direction of the trolley is an acute angle. The lifting hook pulley module is arranged below the trolley pulley module; the switching pulley module is arranged between the lifting hook pulley module and the trolley pulley module, and the switching pulley module can be in switching connection with the trolley or the lifting hook pulley module; and the steel wire rope penetrates in from the first pulley, sequentially bypasses the second pulley, the switching pulley module, the second pulley, the third pulley and the lifting hook pulley module, and then penetrates out from the first pulley. According to the rope winding structure, the steel wire rope does not interfere with the pulley, the neutral performance of the hook pulley module is good, and automatic multiplying power switching is achieved.
本申请涉及工程机械技术领域,公开一种小车与吊钩的滑轮绕绳结构及塔式起重机。该滑轮绕绳结构包括小车滑轮模组、吊钩滑轮模组、切换滑轮模组和钢丝绳;小车滑轮模组包括设置于小车上并沿直线方向分布的第一滑轮、第二滑轮和第三滑轮,且连线方向与小车的长度方向的夹角为锐角;吊钩滑轮模组布置于小车滑轮模组的下方;切换滑轮模组布置于吊钩滑轮模组和小车滑轮模组之间,切换滑轮模组能够与小车或吊钩滑轮模组切换连接;钢丝绳由第一滑轮穿入并依序穿绕过第二滑轮、切换滑轮模组、第二滑轮、第三滑轮及吊钩滑轮模组,再由第一滑轮穿出。本申请公开的绕绳结构钢丝绳不与滑轮干涉,吊钩滑轮模组居中性好,实现自动倍率切换。
