The invention relates to a hoisting machinery lifting rope anti-overwinding protection structure which comprises an installation plate fixedly connected with an external fixing frame, a winch is fixedly installed on the installation plate, a steel wire rope is hinged to a winding roller of the winch, and a hook is fixedly installed at the bottom of the steel wire rope. A protection mechanism used for preventing the hook from colliding with the winch is arranged at the bottom of the mounting plate, and a limiting mechanism used for preventing a winding roller of the winch from rotating is further arranged on the mounting plate. When the top of the hook provides thrust to the baffle, the position of the supporting plate does not move, the distance between the baffle and the supporting plate becomes small, the push rod moves upwards to be matched with the first shifting rod to drive the two L-shaped frames to rotate at the same time, the four supporting blocks press the top of the hook, and the baffle is matched to limit the hook. Dead point damage caused by inclination of the hook is prevented, and therefore the phenomenon that the hook is still prone to overwinding is avoided.

    本发明涉及一种起重机械吊绳防过卷保护结构,包括与外部固定架固定连接的安装板,所述安装板上固定安装有卷扬机,所述卷扬机的收卷辊上铰接有钢丝绳,所述钢丝绳的底部固定安装有挂钩,所述安装板的底部设置有用于防止挂钩与卷扬机发生碰撞的防护机构,所述安装板上还设置有用于阻碍卷扬机的收卷辊转动的限位机构;当挂钩的顶部对挡板提供推力时,而支撑板的位置不发生移动,使得挡板与支撑板之间的距离变小,通过推杆向上移动,配合第一拨杆带动两个L形架同时发生转动,使得四个支撑块对挂钩的顶部提供按压,配合挡板对挂钩提供限位,防止挂钩倾斜导致死点被破坏,从而避免挂钩依旧容易出现过卷现象。
