The ship emergency towing device is a mandatory requirement of (SOLAS) maritime life safety convention, and particularly for liquid cargo carrying ships, special emergency towing devices must be arranged at the two ends of a bow and a stern, and the device can be rapidly unfolded and easily connected with a tugboat when the main power of the ship fails. The emergency towing device should be sufficiently strong and adapted to operate in inclement weather conditions.
The stern tug boat accompanying and towing device is the requirement of international petroleum company association (OCIMF) on liquid cargo carrying ships, and particularly relates to stern accompanying and towing devices which are used for assisting in controlling the state of the ships and completing the control of the ships, wherein the stern accompanying and towing devices are required by all types of liquid cargo ships with the capacity of more than 2 ten thousand tons and are also required to be arranged when the ships pass through narrow water areas or perform special operation besides the emergency towing bands. The accompanying navigation and towing device comprises a strong point with the working load of 100 tons or 200 tons determined by the displacement of the ship and a guide cable block which is arranged on a stern sealing plate and has the same working load.
In the past, the technical scheme that one set of emergency towing device is arranged on a stern deck of a ship and the other set of accompanying and rear towing devices are additionally arranged respectively occupies large space and is difficult to arrange, and the number of outfitting equipment involved is large, so that the defects are obvious. And the latest mooring equipment guide published 2018 by the international oil company association (OCIMF) chapter 4.5.2, concerning the requirement that the emergency towing and accompanying voyage and towing device described above can be arranged in the vessel at the same time, and that there can be a direct towing recovery device for guiding the towing and towing tug towing streamers. Based on the current situations and the characteristic of space limitation of the stern deck of a ship, a towing device with the combined functions of emergency towing, towing ship navigation and towing behind is expected by the industry.

Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1 to 5, a combined function marine towing device includes a pneumatic winch 1, a towing pile 3 and a fairlead block 4 which are fixed on the stern of a ship and sequentially arranged from the bow to the stern along the central axis of the ship; the pneumatic winch 1 is provided with a rope drum, and a rotating shaft of the rope drum is vertical to the central axis of the ship;
a streamer 22 is wound on the rope drum; the front end of the towing cable 22 is provided with an annular cable joint 21, and the tail end of the towing cable 22 is provided with a stop block 23;
a through towing cable passing opening is formed in the middle of the towing pile 3 along the direction of the central axis of the ship; a limiting block extends from the top of the towing pile 3 towards the bow direction of the ship; the caliber of the towing cable passing opening is smaller than that of the stop block 23 and larger than that of the cable joint 21;
the middle part of the cable guide block 4 is provided with a through cable guide port along the direction of the central axis of the ship; the caliber of the cable guide port is larger than that of the cable joint 21.
The trailing pile 3 is of cylindrical configuration.
The pneumatic winch 1, the towing pile 3 and the cable guide block 4 are all fixed on a ship deck.
The fairlead block 4 is arranged at the tail end of the stern part of the ship deck.
The rope reel comprises a main rope reel 11 and a secondary rope reel 12 which are separated from each other, the tread area of the main rope reel 11 is larger than that of the secondary rope reel 12, and the towrope 22 is wound on the main rope reel 11.
The two ends of the rotating shaft of the rope drum are also extended and fixed on the auxiliary winding drum 13.
The streamer 22 is greater than 90 meters in length.
The cable guide opening and the towing cable passing opening are positioned on the same horizontal straight line, and the horizontal straight line is cut at the lower extreme point of the cable drum.
The invention has two using states when using, one is that the device (located in a ship) of the invention extends out the towing rope 22 and connects to other ships to finish connecting, another is that other ships throw out the main cable and connect to the device of the invention to finish connecting, the former is the emergency towing operating mode, the latter is the accompanying navigation and trailing operating mode, the emergency towing and accompanying navigation and trailing under the prior art need two sets of independent devices to realize, and the invention concentrates the function of two sets of devices into one set, its specific use process is as follows:
in the first state, the towing cable 22 is stored on the main rope barrel 11 of the pneumatic winch 1, the stop block 23 on the towing cable 22 is firstly rolled in, the cable joint 21 can extend out to bring the towing cable 22 to sequentially pass through the towing cable passing opening on the towing pile 3 and the cable guiding opening on the cable guiding block 4, the pneumatic winch 1 is driven by the ship emergency air system (when the main power fails) to enable the towing cable 22 to be rolled out of the main rope barrel 11 to be thrown to the sea surface through cooperation of workers, other ships can complete connection of the two ships by picking up the cable joint 21 and connecting the cable joint 21 to a strong point facility special for the other ships, and then emergency towing operation can be carried out, for example, the other ships tow accident power-losing ships back to ports for maintenance. The whole emergency towing device deployment process is very smooth and fast, and completely meets the requirement that the emergency towing device deployment is finished within minutes corresponding to the maritime life safety convention (SOLAS).
In the second state, the main cable is thrown out by other ships, the main cable is connected with a guide cable (the guide cable is light in weight and convenient to operate, and a connecting ring is arranged on the main cable), the guide cable can be thrown to a stern deck of the ship where the device is located, workers on the ship guide the guide cable to an auxiliary drum 13 of the pneumatic winch 1 through a cable guide port, then the pneumatic winch 1 is started to gradually pull the main cable to the position of the towing pile 3 through the auxiliary drum 13, the workers sleeve the double-end connecting ring at the end part of the main cable on the towing pile 3 and limit the position through a limiting block, so that the connection of the two ships is completed, and the accompanying and post towing operation can be carried out.
The main rope reel 11 also rotates integrally with the air winch 1 during the recovery operation of the sub-reel 13, and therefore, the recovery of the knot 21 at the end of the streamer 22 is also carried out. The secondary rope reel 12 can be separately added on the main rope reel 11, the stop block 23 can be firstly wound and stored on the secondary rope reel 12 before the towing rope 22 is wound, and then when the rope section 21 reaches the main rope reel 11, a worker can store the rope section 21 on the secondary rope reel 12 to complete simple binding and fixing. The cable joint 21 after storage and binding can rotate along with the pneumatic winch 1, and the operation of withdrawing the guide cable of the whole system is not influenced.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical solutions and the inventive concepts of the present invention within the technical scope of the present invention.
