The invention relates to the technical field of cable detection work, in particular to a dragging device for winch towing cables. According to the technical scheme of the initiative dragging device, the initiative dragging device is arranged at the end, used for towing cable collecting and releasing, of the winch, and the towing cables of the winch penetrate the initiative dragging device; when the winch releases the cables, the cable releasing speed of a winch barrel is smaller than the cable releasing speed of the initiative dragging device, and outwards pulling acting force can be generatedon the towing cables through the initiative dragging device; and when the winch collects the cables, the cable collecting speed of the winch barrel is larger than the cable collecting speed of the initiative dragging device, and inwards pulling acting force is generated on the towing ropes through the initiative dragging device. By means of the initiative dragging device, it can be ensured that in the cable collecting/releasing process of the winch on the water or under the water, the cables at the end of the winch are in the tensioned state all the time, and it is ensured that the cables onthe winch are arranged in order.

    本发明涉及有缆探测作业技术领域,具体涉及一种绞车拖缆的牵引装置。一种主动牵引装置,其技术方案是:主动牵引装置设置在绞车收/放拖缆的一端,绞车的拖缆从主动牵引装置中穿过;当绞车放缆时,绞车卷筒的放缆线速度小于主动牵引装置放缆线速度,且主动牵引装置对拖缆产生向外拉的作用力;当绞车收缆时,绞车卷筒的收缆线速度大于主动牵引装置收缆线速度,且主动牵引装置对拖缆产生向内拉的作用力。本发明可以保证水上或者水下绞车在收/放缆过程中,绞车端的缆始终处于张紧状态,从而保证绞车上缆的有序排列。
