[0006] As a preferred technical solution of the present invention, rolling groups are slidably installed on both sides of the outer surface of the lifting beam, and reinforcing connecting plates are installed on both sides of the two groups of rolling groups. The two reinforcing connecting plates are fixedly connected to the two lifting ears.

[0007] As a preferred technical solution of the present invention, the movable structure includes two groups of support plates and three counterweights, wherein a fixing ring is fixedly installed on one side of the outer surface of one of the support plates.

[0008] As an optimal technical solution of the present invention, a servo motor is fixedly installed inside the fixing ring, and a bidirectional screw is fixedly installed at one end of the output shaft of the servo motor. The bidirectional screw is rotatably connected to the support plate, and the bidirectional screw is threadedly connected to the reinforcing connecting plates on both sides.

[0009] As a preferred technical solution of the present invention, a limiting rod is rotatably installed between the other group of support plates, and the limiting rod is movably connected to the two groups of reinforced connecting plates.

[0010] As a preferred technical solution of the present invention, the three counterweights are fixedly connected to the two groups of support plates.

[0011] As a preferred technical solution of the present invention, a locking structure is fixedly installed on one side of the outer surface of the two lifting ears, and the locking structure includes two side plates.

[0012] As a preferred technical solution of the present invention, the two side panels are fixedly connected to the lifting ears, and a fixing frame is fixedly installed at one end of the bottom of the two side panels.

[0013] As a preferred technical solution of the present invention, locking rods are movably installed inside the two fixing frames.

[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, first, the loading and unloading buckle is inserted into the lifting ear and locked with the first pin and the first locking nut. Then, the edge of the deck is inserted into the two clamps, and the hole of the edge is aligned with the fixing hole. The second pin is inserted into the fixing hole and the hole of the deck, and then fixed with the second locking nut. In this way, the hoisting and turning can be carried out. When the hoisting and turning is completed, only the second pin at the fixed deck needs to be removed to carry out the next step of the deck hoisting and turning. This structure can be shaken inside the lifting ear through the loading and unloading buckle, which facilitates the deck turning work, thereby achieving the purpose of structural stability, easy disassembly and high durability.

[0017] 2. The car ro-ro ship deck turning hoisting device uses a locking structure. When the hoisting structure lifts the deck, to prevent the loading and unloading buckles from shaking inside the lifting lugs, a locking rod is inserted from one fixing frame, passed between two loading and unloading buckles, and then passed out of the other fixing frame. It is fixed with four fixing bolts. This locks the two loading and unloading buckles in place, preventing the risk of the deck shaking at high altitude. When the hoisting structure drives the deck to turn over, the locking rod can be pulled out of the loading and unloading buckles.

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

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying 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 making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-8 The deck turning-over lifting device for a car roll-on / roll-off ship includes a lifting beam 1 and two lifting structures 2. Hangers 5 are fixedly installed on both sides of the top of the lifting beam 1, and a movable structure 6 is arranged inside the lifting beam 1; the two lifting structures 2 include lifting ears 21, loading and unloading buckles 22 are movably installed inside the two lifting ears 21, and plug-ins 23 are fixedly installed on both sides of the bottom of the two loading and unloading buckles 22, first pins 24 are inserted into the two plug-ins 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 into 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 into the fixing holes 27, and second locking nuts 29 are threadedly installed at 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. The two reinforcing connecting plates 31 are fixedly connected to the two lifting ears 21. The movable structure 6 includes two groups of support plates 61 and three counterweights 65. A fixing ring 62 is fixedly installed on one side of the outer surface of one support plate 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 limiting rod 66 is rotatably installed between the other group of support plates 61, and the limiting 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] Driven by the servo motor 63, its output shaft drives 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 at the same time on the outer surface of the bidirectional screw 64, 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 mounted on one side of the outer surface of the two lifting ears 21. The locking structure 4 comprises two side panels 41. The two side panels 41 are fixedly connected to the lifting ears 21. A fixing frame 42 is fixedly mounted on one end of the bottom of the two side panels 41. Locking rods 43 are movably mounted inside the two fixing frames 42. Fixing bolts 44 are threadedly mounted inside the two fixing frames 42. Two sets of fixing bolts 44 are threadedly connected to the locking rods 43.

[0033] When the hoisting structure 2 lifts the deck, in order to prevent the loading and unloading buckles 22 from shaking inside the lifting ears 21, the locking rod 43 is inserted from the fixed frame 42 on one side, passed through between the two loading and unloading buckles 22, and then passed out from 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 car roll-on / roll-off ship deck turning hoisting device is used, first adjust the position of the two hoisting structures 2 according to the size of the deck, and drive the servo motor 63 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 be simultaneously moved horizontally in opposite directions on the outer surface of the bidirectional screw 64, thereby driving the hoisting structure 2 to move as a whole, so that it can adapt to the turning deck, and then insert the loading and unloading buckle 22 into the lifting ear 21, lock it through the first pin 24 and the first locking nut 25, and then insert the edge of the deck into the two chucks 26, and align the edge holes with the fixing holes 27, and insert the second pin 28 to fix it. The second locking nut 29 is used to fix the hole 27 and the deck hole, 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 deck hoisting and turning over.
