The invention discloses a rescue tug traction device with a protection structure, and relates to the field of rescue tugs. The steel wire rope is adopted as the traction rope, the steel wire rope is high in strength and not prone to breakage, so that the risk of breakage of the traction rope in the traction process can be reduced, meanwhile, the steel wire rope is buffered through the lifting buffering assembly, impulse borne by the steel wire rope at the tightening moment is reduced, and then tension borne by the steel wire rope at the tightening moment is reduced; the steel wire rope is prevented from being snapped, the service life of the steel wire rope is prolonged, and the working safety of the traction device is improved; the steel wire rope is high in strength and small in elastic coefficient, and the deformation cannot be quickly continued by huge tensile force during traction, so that the deformation on the two sides is maximum, and if the steel wire rope is broken, the two ends with the maximum deformation are generally broken, and binding and locking protection structures are arranged at the two ends of the steel wire rope; even if the two ends of the steel wire rope are broken, the steel wire rope cannot be broken, and the use safety of the traction device is further improved.

本发明公开了一种具有防护结构的救助拖轮牵引装置，涉及救助托轮领域。本发明采用钢丝绳作为牵引绳，钢丝绳的强度高，不易断裂，从而能减小牵引过程中牵引绳断裂的风险，同时通过升降缓冲组件对钢丝绳进行缓冲，减小钢丝绳绷紧瞬间所受冲量的大小，进而减小钢丝绳绷紧瞬间所受的拉力，防止钢丝绳被绷断，提高了钢丝绳的使用寿命和牵引装置工作时的安全性；且由于钢丝绳强度高、弹性系数小，牵引时巨大的拉力无法使形变迅速延续下去，从而在两边形变最大，进而使得钢丝绳若发生断裂，一般是形变最大的两端断裂，而通过在钢丝绳的两端设置绑接和锁定防护结构，使得钢丝绳即使两端断裂也不会被崩飞，进一步提高了牵引装置使用时安全性。
