The invention provides a steel wire rope winding preventing device for a crane trolley. The problems that the internal stress of a steel wire rope is increased or decreased and the service life of thesteel wire rope is seriously influenced due to the fact that the lay length of the steel wire rope is not checked before rope winding of a lifting device in the prior art are not effectively solved.According to the technical scheme, the steel wire rope winding preventing device comprises a shell, a roller is arranged in the shell, a hollow cylinder is arranged on the right side of the roller, the end, arranged outside the shell, of the hollow cylinder is sleeved with a rotating cylinder, and a movable plate is arranged on the front side of the shell; a disc is arranged on the front side of the movable plate, a fixed shaft is arranged on the end face of the disc, a sliding cylinder is arranged on the fixed shaft in a sleeving mode, and a plurality of fan-shaped blocks are arranged on thefront side of the disc; and a plurality of connecting rods are hinged to the periphery of the sliding cylinder, the other ends of the connecting rods are hinged to sliding blocks, the disc, the fan-shaped blocks, the connecting rods, the fixed shaft and the sliding cylinder form a variable diameter wheel, a worm capable of rotating in the front-back direction is arranged at the lower end of the movable plate, a worm wheel matched with the worm is arranged on a rotary cylinder, a belt wheel is fixed to the front end of the worm, and the variable diameter wheel and a belt wheel are connected together through a belt.

    本发明提供了一种起重行车防止钢丝绳缠绕装置,有效的解决了现有技术中起吊装置在收绳前没有对钢丝绳的捻距进行校核,造成钢丝绳内部应力变大或者变小,严重影响钢丝绳寿命的问题;其解决的技术方案是,包括壳体,壳体内有滚轮,滚轮右侧有空心筒,空心筒置于壳体外侧的一端上套装有转筒,壳体前侧有活动板;活动板前侧有圆盘,圆盘端面上有固定轴,固定轴上套装有滑筒,圆盘前侧有多个扇形块,滑筒四周铰接有多个连杆,连杆另一端与其滑块铰接,圆盘、多个扇形块、多个连杆及固定轴、滑筒组成变径轮,活动板的下端有沿前后方向且能转动的蜗杆,转筒上有与蜗杆配合的蜗轮,蜗杆前端固定有带轮,变径轮与带轮之间经皮带连接在一起。
