Automatic disengaging device for steel wire rope

The invention discloses an automatic releasing device for a steel wire rope. According to the automatic releasing device, aiming at the characteristics that in the process of putting down a jacket from a vertical state to a horizontal state, a limiting column horizontally welded on the jacket is changed from the horizontal state to the vertical state, vertically upward buoyancy can be provided after a buoy enters water, and the buoyancy can drive a lute head of the steel wire rope to slide on the limiting column, the automatic releasing device solves the problem that the steel wire rope applies a reverse force to a tug in the process of dragging and putting down the jacket is successfully solved, and the construction risk and the construction difficulty in the process of dragging and putting down the jacket are greatly reduced. 本发明公开了一种钢丝绳自动解脱装置，针对导管架在由立式转为卧式的放倒过程中，其上水平焊接的限位柱则会由水平转为竖直，通过利用浮筒入水后可提供竖直向上的浮力，而该浮力能带动钢丝绳的琵琶头在限位柱上滑动的特点，本发明成功解决了导管架拖拉放倒过程中钢丝绳对拖轮施加反向力的问题，大大降低了导管架拖拉放倒作业过程中的施工风险和施工难度。
