The invention discloses a structure provided with a ratchet wheel assembly and used for preventing a clamping rope from loosening. The structure comprises a rotating shaft used for driving a forward rotating and reverse braking ratchet wheel to rotate, and the ratchet wheel is matched with a braking structure to prevent the steel wire rope from falling off due to reverse movement of a tapered wedge used for clamping the steel wire rope. The brake structure comprises a pawl matched with the ratchet wheel for braking and a push-off handle matched with the pawl, and the brake structure is used for releasing reverse braking force of the ratchet wheel. The structure has the beneficial effects that the structure occupies small space and is time-saving and labor-saving, the ratchet wheel assembly is used for preventing reverse rotation, motor braking and manual operation are replaced, operation is simple, maintenance and repair are convenient, and it is ensured that the tapered wedge does not move reversely to cause falling of the steel wire rope. The rope can be quickly adjusted, and the safety coefficient is greatly improved.

    本发明公开了一种带有棘轮组件防止卡绳松动的结构,包括用于带动正向旋转反向制动棘轮旋转的旋转轴,所述棘轮与制动结构相配合,实现防止用于夹紧钢丝绳的斜楔反向运动致使钢丝绳脱落。所述制动结构包括与棘轮相配合制动的棘爪及与所述棘爪相配合的推离柄,用于脱离与所述棘轮的反向制动力。本发明的有益效果是:结构占用空间小,省时省力,用棘轮组件防止反转,代替电机制动,手动操作,操作简单,便于维护和维修,确保斜楔不会形成反向运动致使钢丝绳脱落。能够实现快速调绳,极大的提升安全系数。
