[0002] Ship hoist is an important mechanical equipment on board. It is a device and machinery used by the ship to load and unload cargo. It mainly includes boom devices, deck cranes and other loading and unloading machinery. It is mainly used for important tasks such as transportation and transfer of cargo between ships, marine replenishment, and the deployment and recovery of underwater operating equipment. The special application environment at sea brings great challenges to the control of marine cranes. The crane is fixed on a moving platform such as a ship. The movement of the platform itself will have a strong impact on the movement of the load. In many cases, the movement of the load at the lifting and landing point is inconsistent with the movement of the crane itself.

[0003] During operation, the ship elevator will pitch, roll or heave with the waves, sliding friction will be generated when the wire rope moves, and the wire rope will wear when lifting cargo. Long-term use may cause breakage, which poses certain safety hazards. In addition, the ship elevator is generally fixed on the deck and has poor flexibility. For this reason, we propose a ship lifting device based on image monitoring and a method thereof. Summary of the invention

[0022] S2. When the angle needs to be adjusted, the output end of the second motor drives the transmission gear to rotate, the transmission gear drives the crown gear to rotate at a reduced speed, the crown gear drives the linkage shaft to rotate slowly, and finally drives the support seat to rotate horizontally. The output end of the first hydraulic rod is extended or shortened to adjust the support angle of the multi-stage boom.

[0024] S5. During the movement of the wire rope, the through-axis tension detector can monitor the surface tension of the wire rope in real time, and the second camera can record the surface of the wire rope in real time to detect whether there is any breakage on the surface.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. In this scheme, both steel wire ropes are wound in the double-track gallows. When working, the output end of the third motor drives the active sprocket to rotate, and finally drives the double-track gallows to rotate. The hook rises and falls with the movement of the steel wire rope. Compared with the existing lifting object with one steel wire rope, it can enhance the strength and reduce the occurrence of breakage.

[0027] 2. In this solution, during the movement of the wire rope, both wire ropes will pass through the through-axis tension detector, and the tension of the wire rope will be monitored in real time through the through-axis tension detector. The second camera can capture the surface condition of the wire rope in real time, and the hook can record the condition of the connection between the hook and the wire rope. In actual use, the through-axis tension detector, the second camera and the hook can be connected to the monitoring equipment, and the wire rope, the second camera and the hook will send data information to the monitoring equipment in real time. The monitoring equipment can judge the use of the wire rope to avoid breakage and improve safety.

[0028] 3. When movement is required, the output end of the first motor drives the ball screw to rotate, and the ball screw drives the screw sleeve to move, thereby driving the bottom plate to move, so as to achieve the purpose of moving the base. The base is moved within a certain range and the lifting position is adjusted. Compared with the existing ship crane, it is more flexible to use, and the roller rolls in the wheel rail as the base moves, making the base movement more stable and will not deviate.

[0029] 4. When the mounting plate is not in use, the output end of the cylinder drives the block to move so that the block is inserted into the slot. The block blocks the mounting plate from rotating, thereby blocking the double-track gallows from rotating. This can prevent the third motor from malfunctioning and causing the hook to fall rapidly, thereby improving safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] In a specific embodiment of the present invention, the steel wire rope 29 passes through the through-axis tension detector 31 when it moves. The tension of the steel wire rope 29 can be monitored in real time through the double-track gallows 21. When the tension of the steel wire rope 29 changes, the steel wire rope 29 may break, reminding the staff to conduct inspection. The steel wire rope 29 passes through the upper side of the second camera 37 when it moves. The second camera 37 can photograph the surface condition of the movable shaft 39 to observe whether there are signs of breakage on its surface, thereby effectively improving safety.

[0073] S4. When it is necessary to lift an object, the output end of the third motor 18 drives the active sprocket 19 to rotate, and then drives the double-track gallows 21 to rotate. When the double-track gallows 21 rotates, it can drive the two steel wire ropes 29 to move, and finally drive the hook 36 to rise and fall, so as to achieve the purpose of lifting the object.

2. A method for a ship lifting device based on image monitoring, characterized in that: The ship lifting device based on image monitoring described in claim 1 is used, comprising the following steps: S1. When the position of the base (1) needs to be moved, the ball screw (6) is driven to rotate through the output end of the first motor (7), and finally the base (1) is driven to move. When the base (1) moves, the roller (9) rolls in the wheel rail (5) to keep the base (1) able to move stably; S2. When the angle needs to be adjusted, the output end of the second motor (13) drives the transmission gear (14) to rotate, the transmission gear (14) drives the crown gear (12) to rotate at a reduced speed, the crown gear (12) drives the linkage shaft (11) to rotate slowly, and finally drives the support seat (3) to rotate horizontally. The output end of the first hydraulic rod (38) is extended or shortened, so that the support angle of the multi-stage boom (16) can be adjusted; S4. When it is necessary to lift an object, the output end of the third motor (18) drives the driving sprocket (19) to rotate, and then drives the double-track gallows (21) to rotate. When the double-track gallows (21) rotates, it can drive the two steel wire ropes (29) to move, and finally drive the hook (36) to rise and fall, so as to achieve the purpose of lifting the object; S5. During the movement of the steel wire rope (29), the through-axis tension detector (31) can monitor the surface tension of the steel wire rope (29) in real time, and the second camera (37) can record the surface of the steel wire rope (29) in real time to detect whether there is any breakage on the surface.
