[0014] As a preferred technical solution of the present invention, fixing bolts are installed on the internal threads of the two fixing frames, and the two groups of fixing bolts are threadedly connected to the locking rods.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The car ro-ro ship deck turning hoisting device, through the hoisting structure, when hoisting and turning the car ro-ro ship deck, firstly, the loading and unloading buckle is inserted into the lifting ear, and locked by the first pin and the first locking nut, then the edge of the deck is inserted into the two chucks, and the hole of the edge is aligned with the fixing hole, and the second pin is inserted into the fixing hole and the hole of the deck, and then the second locking nut is used to fix it, so that the hoisting and turning can be carried out. When the hoisting and turning are completed, only the second pin at the fixed deck needs to be removed, and the next step of the deck hoisting and turning work can be carried out. This structure can be shaken in the lifting ear through the loading and unloading buckle, which is convenient for the turning of the deck, thereby achieving the purpose of stable structure, convenient disassembly and high durability;

[0017] 2. The deck turning hoisting device for a car ro-ro ship has a locking structure. When the hoisting structure hoists the deck, in order to prevent the loading and unloading buckles from shaking inside the lifting ears, the locking rod is inserted from a fixing frame on one side, passed between two loading and unloading buckles, and then passed out from a fixing frame on the other side, and fixed by four fixing bolts. In this way, the two loading and unloading buckles can be locked in position to prevent the deck from shaking in the air and causing risks. When the hoisting structure drives the deck to turn over, the locking rod can be pulled out from the loading and unloading buckles;

[0018] 3. The car roll-on / roll-off ship deck turning hoisting device, through the mobile structure, when the deck is hoisted and turned over, is driven by the servo motor so that its output shaft drives the bidirectional screw to rotate. Due to the limitation of the limit rod on the other side, the two sets of reinforcing connecting plates can move horizontally in opposite directions on the outer surface of the bidirectional screw at the same time, thereby driving the hoisting structure to move as a whole, so that it can adapt to decks of different sizes, improving the wide applicability of the device. At the same time, due to the setting of the three counterweights, the hoisting beam as a whole can maintain balance and stability when hoisting and moving. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-8 The deck turning hoisting device for a car ro-ro ship comprises a hoisting beam 1 and two hoisting structures 2. Hangers 5 are fixedly installed on both sides of the top of the hoisting beam 1, and a movable structure 6 is arranged inside the hoisting beam 1; the two hoisting structures 2 comprise lifting ears 21, loading and unloading buckles 22 are movably installed inside the two lifting ears 21, plug plates 23 are fixedly installed on both sides of the bottom of the two loading and unloading buckles 22, first pins 24 are inserted inside the two plug plates 23, first locking nuts 25 are threadedly installed on both sides of the outer surfaces of the two first pins 24, chucks 26 are inserted on the outer surfaces of the two first pins 24, two groups of fixing holes 27 are opened on the outer surfaces of the two chucks 26, second pins 28 are inserted inside the fixing holes 27, and second locking nuts 29 are threadedly installed on both ends of the outer surfaces of the two second pins 28.

[0030] See also Figure 3-5 , rolling groups 3 are slidably installed on both sides of the outer surface of the lifting beam 1, and reinforcing connecting plates 31 are installed on both sides of the two rolling groups 3, and the two reinforcing connecting plates 31 are fixedly connected to the two lifting ears 21. The moving structure 6 includes two groups of support plates 61 and three counterweights 65, and a fixing ring 62 is fixedly installed on one side of the outer surface of one of the support plates 61. A servo motor 63 is fixedly installed inside the fixing ring 62, and a bidirectional screw rod 64 is fixedly installed on one end of the output shaft of the servo motor 63. The bidirectional screw rod 64 is rotatably connected to the support plate 61, and the bidirectional screw rod 64 is threadedly connected to the reinforcing connecting plates 31 on both sides. A limit rod 66 is rotatably installed between the other group of support plates 61, and the limit rod 66 is movably connected to the two groups of reinforcing connecting plates 31. The three counterweights 65 are fixedly connected to the two groups of support plates 61.

[0031] The servo motor 63 is driven to make its output shaft drive the bidirectional screw 64 to rotate. Due to the limitation of the limiting rod 66 on the other side, the two sets of reinforcing connecting plates 31 can move horizontally in opposite directions on the outer surface of the bidirectional screw 64 at the same time, thereby driving the lifting structure 2 to move as a whole, so that it can adapt to decks of different sizes.

[0032] See also Figure 6-8A locking structure 4 is fixedly installed on one side of the outer surface of the two lifting ears 21, and the locking structure 4 includes two side plates 41. The two side plates 41 are fixedly connected to the lifting ears 21, and a fixing frame 42 is fixedly installed at one end of the bottom of the two side plates 41. Locking rods 43 are movably installed inside the two fixing frames 42. Fixing bolts 44 are threadedly installed inside the two fixing frames 42, and two sets of fixing bolts 44 are threadedly connected to the locking rods 43.

[0033] When the deck is lifted by the lifting structure 2, in order to prevent the loading and unloading buckles 22 from shaking inside the lifting ears 21, the locking rod 43 is inserted into the fixed frame 42 on one side, passed through between the two loading and unloading buckles 22 and then out of the fixed frame 42 on the other side, and fixed by four fixing bolts 44. In this way, the two loading and unloading buckles 22 can be limited and locked to avoid the risk of the deck shaking in the air.

[0034] Working principle: when the deck turning hoisting device for car roll-on / roll-off ship is used, the positions of the two hoisting structures 2 are first adjusted according to the size of the deck. The servo motor 63 is driven to make its output shaft drive the bidirectional screw 64 to rotate. Due to the limitation of the limit rod 66 on the other side, the two sets of reinforcing connecting plates 31 can move horizontally in opposite directions on the outer surface of the bidirectional screw 64 at the same time, thereby driving the hoisting structure 2 to move as a whole, so that it can adapt to the turning deck. Then, the loading and unloading buckle 22 is inserted into the lifting ear 21, and locked by the first pin 24 and the first locking nut 25. Then, the edge of the deck is inserted into the two chucks 26, and the edge holes are aligned with the fixing holes 27. The second pin 28 is inserted to fix it. The second locking nut 29 is used to fix the hole 27 and the hole in the deck, so that the deck can be hoisted and turned over. When the hoisting structure 2 lifts the deck, in order to prevent the loading and unloading buckle 22 from shaking inside the lifting ear 21, the locking rod 43 is inserted from the fixed frame 42 on one side, passes through between the two loading and unloading buckles 22 and then passes through the fixed frame 42 on the other side, and is fixed by four fixing bolts 44. In this way, the two loading and unloading buckles 22 can be limited and stuck to avoid the risk of the deck shaking in the air. When the hoisting structure 2 drives the deck to turn over, the locking rod 43 can be pulled out from the loading and unloading buckle 22. When the hoisting and turning disassembly is completed, it is only necessary to remove the second pin 28 at the fixed deck to proceed to the next step of hoisting and turning over the deck.
