[0027] See also Figure 5The winch 6 includes a capstan, a motor, a bracket and a central axis. The bracket is welded on the second deck, the motor is arranged inside the capstan, and the capstan is fixed to the bracket through the central axis. A rotating rail 17 is arranged at the front end of the bracket, and two cross rails are arranged on the outer surface of the rotating rail 17. The rotating rail 17 is slidably connected to the guide chain block 16. The internal pin of the guide chain block 16 is connected to the slider 18. The bottom of the guide chain block 16 is threadedly connected to the connecting rod 19. The connecting rod 19 is slidably connected to the second slide rail 20.

[0028] See also Figure 6 The reel 21 includes a reel holder, a reel and a connecting shaft. The reel holder is welded in the second storage box 8. The reel holder and the reel are connected with a connecting shaft. The connecting shaft gear is connected to the pneumatic motor 22. The pneumatic motor 22 needs to be connected to an external air source.

[0029] In order to cope with LNG fuel tankers of different tonnages, in the embodiment of the utility model, the diameter of the anti-friction chain 4 includes one or more combinations of 60mm, 70mm, 76mm, and the diameter of the towing rope 11 includes one or more combinations of 70mm, 80mm, 90mm steel wire cables, ensuring that the steel wire cables will not break during emergency towing.

[0030] In order to cope with LNG fuel tankers of different tonnages, in the embodiment of the present utility model, the length of the traction rope 13 is between 140m and 160m. For example, when the second deck of the LNG fuel tanker is too high, the length of the traction rope 13 needs to be lengthened.

[0031] Working principle: In the storage state, the anti-friction chain 4 is hoisted into the first storage box 5 by using the crane 14, the traction rope 13 is wound up on the reel using the drum 21 and stored in the second storage box 8, and when the winch 6 is wound up, the internal motor drives the belt 15, and the belt 15 drives the rotating rail 17 to rotate, and the slider 18 slides along the track inside the rotating rail 17 to drive the guide chain block 16 to move, and the guide chain block 16 drives the connecting rod 19 to move left and right on the second slide rail 20, and the connecting rod 19 remains vertical to ensure that the guide chain block 16 does not rotate, and the winch 6 winds the retrieval rope 10 and the towing cable 11 on the winch.

[0032] When emergency towing is needed, the crane 14 lifts the anti-scratch chain 4, fixes one end of the anti-scratch chain 4 in the chain stopper 1, and the other end passes through the first fairlead 3 and is connected to the tugboat for front emergency towing. The winch 6 releases the retrieval rope 10 and the towing cable 11 and passes one end of the towing cable 11 through the towing pile 9, uses the connecting chain 12 to connect the towing cable 11 with the towing rope 13, releases the drum 21, and passes the other end of the towing rope 13 through the second fairlead 7 to connect to the tugboat for rear emergency towing. The first fairlead 3 and the second fairlead 7 can allow the anti-scratch chain 4 and the towing cable 11 to be towed in two directions at the same time, 90 degrees to the left and right and 30 degrees downward, respectively, to ensure that the chain will not break.

[0033] When an LNG fuel tanker is operating at a port, if a serious fire or explosion occurs on the ship or the shore, or the main power of the ship fails, the front and rear emergency towing devices can be connected to the tugboat at the same time, and the lateral movement can quickly move the relevant ship to a safe area to reduce losses. This realizes the use of special functions of special equipment, solves the problem of complicated and laborious actual operation caused by the use of multiple devices, and has complete functions to meet various needs for emergency towing.
