Embodiment Construction
[0010] Such as figure 1 As shown, the dragging winch of the present invention includes a main shaft 4 with a damping rope release mechanism, and the two ends of the main shaft 4 are respectively mounted on the first support 1 and the second support 5 in a movable manner by means of bearings 2, and the center of the main shaft 4 is fixed with a reel The gear on the shaft meshes with the gear 3. One end of the main shaft 4 protrudes outside the second bracket 5, the extended end of the main shaft 4 is connected with a support shaft 11, and the static friction plates 6 are evenly distributed along the outer circular axis of the support shaft 11, and the static friction plates 6 are connected with the support The shafts 7 are fixed together. There are gaps between adjacent static friction plates 6 . The radially outer side of the static friction plate 6 is provided with a support rod 7, and the inner end of the support rod 7 is fixed on the second bracket 5, and a dynamic fricti...

The invention discloses a damping pay-off mechanism for towing winches, and particularly relates to a damping pay-off mechanism used for tensioning of cables between the towing winches and towed ships. The damping pay-off mechanism is characterized in that the damping pay-off mechanism comprises a spindle, two ends of the spindle are movably mounted on a first support and a second support respectively, and a gear is fixed in the middle of the spindle. One end of the spindle extends out of the second support and is connected with a supporting shaft. Static friction pieces are evenly and axially distributed on the outer circle of the supporting shaft. Supporting rods are arranged on the radial outer sides of the static friction pieces. The inner ends of the supporting rods are connected with the second support. Dynamic friction pieces are evenly distributed between the supporting rods and the supporting shaft. The number of the dynamic friction pieces is identical to and corresponding to the number of gaps of the dynamic friction pieces. The outer ends of the dynamic friction pieces are connected to the supporting rods, and the other ends of the dynamic friction pieces extend into gaps between every two corresponding static friction pieces. Air bags are sleeved at the outer ends of the supporting rods, and compacting pieces are arranged on the air bags. By the damping pay-off mechanism, service life of the cables can be prolonged, and pay-off efficiency is improved.
Description
technical field [0001] The invention relates to a winch. Specifically, it is a damping rope release mechanism used to tension the cable between the towing winch and the towed ship. Background technique [0002] It is well known in the shipbuilding and application fields that large ships are equipped with towing winches in order to tow some special ships. When the towing winch is needed to tow the ship, the cables on the towing winch need to be unclamped so that the towed ship is connected. In the process of releasing the rope, due to the heavy weight of the cable, the middle part of the cable sags to touch the water surface or sink into the seabed, so it is difficult to accurately know the actual length of the cable to be released. Because the sagging middle part of the cable will touch the water surface or sink into the seabed, the cable will be rusted and damaged over time, thereby reducing the service life of the cable. Again because it is difficult to know the actual ...
