The invention provides a rope skipping prevention device for winding multiple layers of steel wire ropes on a duplex winding drum, the rope skipping prevention device is arranged on a trolley frame and located between the trolley frame and the duplex winding drum, and the rope skipping prevention device comprises a first mounting seat, a second mounting seat and a guide rod, the rope skipping prevention device comprises a first installation base and a second installation base, the two ends of each guide rod are arranged on the first installation base and the second installation base respectively, a plurality of guide grooves are formed in the outer side of each guide rod, and at least one end of each guide rod can move in the direction close to the duplex winding drum. When the steel wire rope is wound or released on the duplex winding drum, a large included angle is not generated between the steel wire rope and the radial direction of the duplex winding drum corresponding to the position of the steel wire rope, so that the rope skipping phenomenon is effectively avoided; therefore, the safety of the duplex winding drum in the process of winding or releasing the steel wire rope is improved.

    本发明提供一种用于双联卷筒卷绕多层钢丝绳的防跳绳装置,所述防跳绳装置设于小车架上,并位于所述小车架与双联卷筒之间,所述防跳绳装置包括第一安装座、第二安装座和导杆,所述导杆的两端分别设于所述第一安装座和所述第二安装座上,所述导杆外侧设有多个导槽,所述导杆至少一端可朝着靠近所述双联卷筒的方向运动,本发明通过对应的所述防跳绳装置对所述钢丝绳进行导绳,能够使得所述钢丝绳在所述双联卷筒上进行卷绕至或释放时,不会与所述钢丝绳所在位置所对应的所述双联卷筒的径向之间产生较大的夹角,从而有效的避免了跳绳现象的发生,从而提升了所述双联卷筒在进行所述钢丝绳卷绕或释放过程中的安全性。
