The invention relates to the technical field of winch safety protection, and provides a twisted rope overload protection device which comprises an induction wheel. The shaft body is arranged in the axial through hole of the induction wheel in a penetrating manner; the insulation elastic sleeve is arranged between the induction wheel and the shaft body in a sleeving mode so as to support a gap between the induction wheel and the shaft body, the gap corresponds to the pressed position of the induction wheel, and the pressed position of the induction wheel is suitable for abutting against a twisted rope; the conductive part is used for being electrically connected with the induction wheel and the shaft body; the two ends of the shaft body are rotationally connected between the pair of supporting plates; the pressed position of the induction wheel is pressed by the twisted rope, the inner surface of the induction wheel makes contact with the shaft body, the conductive part conducts electricity and outputs an electric signal, the rope pressing effect on the twisted rope is achieved, the twisted rope is prevented from being too loose, meanwhile, when the twisted rope is overloaded, the load work of the twisted rope is closed in time, the structure is simple, and the cost is low.

    本发明涉及绞车安全保护技术领域,提供一种绞绳过载保护装置,包括感应轮;轴体,穿设于所述感应轮的轴向通孔;绝缘弹性套,所述绝缘弹性套套设于所述感应轮和所述轴体之间,以支撑所述感应轮与所述轴体之间具有间隙,且所述间隙对应于所述感应轮的受压位置,所述感应轮的受压位置适于抵接绞绳;导电部,用于分别与所述感应轮和所述轴体电连接;一对支撑板,所述轴体的两端转动连接于一对所述支撑板之间;在所述感应轮的受压位置受到绞绳压迫并使得所述感应轮的内表面与所述轴体接触,所述导电部导电并输出电信号,实现了对绞绳的压绳作用,避免绞绳过于松弛,同时在绞绳过载时,及时关闭绞绳的负载工作,结构简单,成本低廉。
