The embodiment of the invention provides a rope skipping prevention structure and engineering machinery, and relates to the technical field of engineering machinery. The rope skipping prevention structure comprises a support, a check ring and a damping assembly, the check ring is movably connected with the support, the support and the check ring jointly form a containing frame, a steel wire rope penetrates through the containing frame, and the damping assembly is connected with the check ring and the support; and the damping assembly is used for reducing the motion amplitude of the steel wirerope in the containing frame. The containing frame formed by the rope skipping prevention structure can limit the moving range of the steel wire rope, the damping assembly can relieve impact of the steel wire rope on the check ring and the support, the structure is reliable, the buffering effect is good, and the problem of rope skipping caused by too large amplitude of the steel wire rope can be effectively avoided.

    本发明的实施例提供了一种防跳绳结构和工程机械,涉及工程机械技术领域。该防跳绳结构包括支架、挡圈和减震组件,挡圈可活动地连接在支架上,支架和挡圈共同形成容置框,容置框用于供钢丝绳穿过,减震组件分别与挡圈和支架连接;减震组件用于减小钢丝绳在容置框内的运动振幅。该防跳绳结构形成的容置框能够限定钢丝绳的移动范围,并且减震组件的设置能够缓减钢丝绳对挡圈以及支架的冲击,结构可靠,缓冲效果好,能够有效避免钢丝绳振幅过大而“跳绳”的问题。
