Abstract
Description
Technical Field
[0001] This invention belongs to the field of marine technology, specifically a winch control system with a load adaptive mechanism. Background Technology
[0002] A high-speed workboat launching and recovering device is a piece of equipment installed on ships for launching and recovering workboats. Since workboats often operate in high sea states, this device is crucial for quickly and safely lowering the workboat to the surface and safely recovering the boat and personnel back to the mother ship. The hydraulic winch of the launching and recovering device is typically equipped with wave compensation, i.e., constant tension. As the workboat is slowly lowered to the surface, the constant tension system automatically activates. At this time, the winch wire rope connected to the workboat hook quickly tensions and maintains a constant tension, ensuring the workboat follows the waves until the rescue boat disengages from the hook. The magnitude of the winch's constant tension is adjusted by the overflow valve on the winch's hydraulic motor valve assembly.
[0003] The varying number of crew members on the workboat leads to significant variations in the winch load of the retrieval and deployment system. Furthermore, for workboats with dual lifting points, the shift in the boat's center of gravity results in completely different loads on the bow and stern hooks. Maintaining a fixed constant tension throughout the retrieval and deployment process would lead to poor compensation for changes in the winch wire rope load, and could even cause accidents such as the workboat being pulled off course due to excessive tension. Therefore, it is necessary to design a control system that can sense the winch wire rope load in real time and automatically adjust the overflow valve setting to adapt to the load, enabling safer and more efficient retrieval and deployment of the workboat. Summary of the Invention

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0024] Implementation examples, by Figures 1 to 7The present invention discloses a winch control system with a load adaptive mechanism, comprising a workboat 1, a wire rope 2, a fixed pulley 3, a pin-type tension sensor 4, a hydraulic winch 5, a rotary encoder 6, a PLC controller 7, a hydraulic motor 8, a hydraulic brake 9, an electro-proportional relief valve 10, a hydraulically controlled switching valve 11, a solenoid switching valve 12, a hydraulically controlled directional valve 13, a shuttle valve 14, a pressure reducing valve 15, a main control valve 16, and a main boom 17. The main control valve 16, the main boom 17, and the PLC controller 7 are all mounted on the top of the hull 18. The fixed pulley 3 is connected to the main boom 17 via the pin-type tension sensor 4, which bears the load and converts changes in load into current signals that are transmitted to the PLC controller 7. The hydraulic winch 5 is mounted on the main boom 17. At one end, the rotary encoder 6, hydraulic motor 8, and hydraulic brake 9 are all mounted on the hydraulic winch 5. The rotary encoder 6 is used to detect the working height of the wire rope 2. The output shaft of the rotary encoder 6 is connected to the output shaft of the hydraulic winch 5 through a coupling, and can operate synchronously with the hydraulic winch 5. It can convert the motion signal of the hydraulic winch 5 into an electrical pulse signal and transmit it to the PLC controller 7. The hydraulic motor 8 is connected to the main control valve 16 through the hydraulic pipeline. The electro-proportional relief valve 10, the hydraulic control switch valve 11, the solenoid switch valve 12, the hydraulic control directional valve 13, the shuttle valve 14, and the pressure reducing valve 15 are all mounted on the hydraulic pipeline and are used to control the flow direction, flow rate, and pressure of the hydraulic oil. One end of the wire rope 2 is connected to the hydraulic winch 5, and the other end of the wire rope 2 passes through the fixed pulley 3 and is connected to the hook of the workboat 1.
[0025] The hydraulic winch 5 is mounted on the main boom 17 of the launching and retracting device. The wire rope 2 of the hydraulic winch 5 is connected to the hook of the working boat 1 through the fixed pulley 3. The support shaft of the fixed pulley 3 adopts a pin-type tension sensor 4 with tension sensing function. This sensor can not only bear the load but also convert the change of the load into a current signal and transmit it to the PLC controller 7. A rotary encoder 6 is installed on the side of the hydraulic winch 5 to detect the working height of the winch wire rope. The output shaft of the encoder is directly connected to the output shaft of the winch and always operates synchronously with the winch. The motion signal of the winch is also converted into an electrical pulse signal and transmitted to the PLC controller 7.
[0026] When the winch is operating in constant tension mode, the electric control handle of the main control valve 16 is always in the "lifting" state. The hydraulic power source outputs hydraulic oil through the main control valve, one path directly to port B of the hydraulic motor 8 for lifting, and the other path through the shuttle valve 14, pressure reducing valve 15, and hydraulic control directional valve 13 to open the hydraulic brake 9, so that the hydraulic motor 8 always remains in a floating state, following the rise and fall of the waves in both directions. When the winch is in constant tension mode, the solenoid switch valve 12 and the hydraulic control directional valve 13 are also energized at the same time, so that the electro-proportional relief valve 10 is in working state. The magnitude of the constant tension is adjusted by the electro-proportional relief valve 10. This valve can adjust the relief valve setting value by the input current signal. When the wave is descending and the tension of the winch wire rope is greater than the relief valve setting value, the winch is passively lowered. When the wave is rising and the tension of the winch wire rope is less than the relief valve setting value, the winch is actively lifted, thereby completing the wave-following action.
[0027] If the constant tension setting value of the electro-proportional relief valve 10 is set according to the full crew of the boat, but there are fewer crew members on board during actual operation, the pin-type tension sensor 4 detects that the weight of the boat is lighter than the set value. Then, the weight change signal is transmitted to the PLC controller 7. After comparison and calculation by the PLC controller 7, the current signal output to the electromagnetic proportional relief valve 10 is reduced, which reduces the opening pressure of the relief valve and reduces the constant tension value of the winch. When the waves drop, the tension of the winch wire rope is greater than the set value of the relief valve, and the speed of the winch being passively lowered becomes faster, thus better adapting to the sea conditions.
[0028] The hydraulic winch 5 consists of a frame 19, a reducer 20, a drum 21, and a wire rope limiting assembly 22. The frame 19 is fixedly mounted on the main boom 17. The drum 21 is installed inside the frame 19. The reducer 20 is installed between the hydraulic motor 8 and the frame 19 and connected to the drum 21. The wire rope limiting assembly 22 is installed on the side of the frame 19 and fits against the wire rope 2. The wire rope limiting assembly 22 consists of a support 23, a V-shaped support arm 24, a support shaft 25, a first limiting pressure roller 26, a second limiting pressure roller 27, a tension spring 28, and a tension spring 29. The support 23 is fixedly connected to the frame 19, and the V-shaped support arm... One end of the support arm 24 is hinged to the support 23, and the support shaft 25 is fixedly connected to the other end of the V-shaped support arm 24. The first limiting pressure roller 26 and the second limiting pressure roller 27 are respectively sleeved on both ends of the support shaft 25 and rotatably connected to the support shaft 25 through bearings. Tension spring 1 28 and tension spring 29 are both connected between the V-shaped support arm 24 and the frame 19. One end of tension spring 1 28 and tension spring 29 are fixedly connected to the frame 19 through the L-shaped connecting plate 30. The other end of tension spring 1 28 and tension spring 29 are fixedly connected to the end of the V-shaped support arm 24 near the first limiting pressure roller 26 and the second limiting pressure roller 27 through the hole bolt 31.
[0029] The frame 19 supports the reducer 20, drum 21 and wire rope limiting assembly 22. The reducer 20 can reduce the speed of the drum 21. The wire rope limiting assembly 22 can press and limit the wire rope 2 on the drum 21 to prevent the wire rope 2 from loosening. Tension spring 1 28 and tension spring 29 continuously apply tension to the V-shaped support arm 24. The V-shaped support arm 24 drives the support shaft 25 to press down. The support shaft 25 drives the first limiting pressure roller 26 and the second limiting pressure roller 27 to continuously press the wire rope 2 and has a rotation function, thereby reducing friction.
[0030] One end of the main boom 17 is hinged to the hull 18. A hydraulic rod 32 is provided between the main boom 17 and the hull 18. The two ends of the hydraulic rod 32 are respectively hinged to the main boom 17 and the hull 18, which can adjust the main boom 17. Inside the main boom 17, at the end away from the hull 18, there are guide wheels 33 and 34 that match the wire rope 2, which can limit the bearing position of the wire rope 2.
[0031] A deflection prevention and positioning component 35 is fixedly installed at the end of the main boom 17 away from the hull 18, which is sleeved on the wire rope 2. The deflection prevention and positioning component 35 consists of a support column 36, a telescopic sleeve 37, a telescopic sleeve 38, two hydraulic telescopic rods 39 and 40. The telescopic sleeve 37 is sleeved on the bottom end of the support column 36. The hydraulic telescopic rod 39 is connected between the support column 36 and the telescopic sleeve 37. The telescopic sleeve 38 is sleeved on the bottom end of the telescopic sleeve 37. The hydraulic telescopic rods 39 and 40 are also connected. 40 is connected between telescopic sleeve 1 37 and telescopic sleeve 2 38. The support column 36 is welded with mounting plate 1 41 that matches hydraulic telescopic rod 1 39. The telescopic sleeve 1 37 is welded with mounting plate 2 42 that matches hydraulic telescopic rod 1 39 and hydraulic telescopic rod 2 40. The telescopic sleeve 2 38 is welded with mounting plate 3 43 that matches hydraulic telescopic rod 2 40. The two sides of the bottom end of the telescopic sleeve 2 38 are rotatably provided with limiting groove wheel 1 44 and limiting groove wheel 2 45 that match wire rope 2.
[0032] During the deployment and retrieval of workboat 1, it may sway violently due to the sea breeze and waves. At this time, hydraulic telescopic rod 2 40 drives telescopic sleeve 2 38 to rise and fall, and hydraulic telescopic rod 1 39 drives telescopic sleeve 1 37 to rise and fall. This can help limit the steel wire rope 2, reduce the swaying amplitude of workboat 1, and improve the safety of workboat 1. Limiting groove wheel 1 44 and limiting groove wheel 2 45 can prevent the steel wire rope 2 from rubbing against telescopic sleeve 2 38.
[0033] In operation, a control system comprised of a fixed pulley, a pin-type tension sensor, a hydraulic winch, a rotary encoder, a PLC controller, a hydraulic motor, a hydraulic brake, an electro-proportional relief valve, a hydraulically controlled switching valve, a solenoid switching valve, a hydraulically controlled directional valve, a shuttle valve, a pressure reducing valve, a main control valve, and a main boom structure can automatically adjust the tension value according to changes in the wire rope load. This allows the retrieval and deployment device to launch and retrieve the workboat more safely and efficiently, better adapting to sea conditions and improving the safety and stability of the workboat's launch and retrieval. A wire rope limiting assembly, consisting of a support, a V-shaped support arm, a support shaft, a first limiting pressure roller, a second limiting pressure roller, and tension springs one and two, is installed to compress and limit the wire rope, preventing it from loosening. An anti-deviation positioning assembly, consisting of a support column, a telescopic sleeve one, a telescopic sleeve two, two hydraulic telescopic rods one and two hydraulic telescopic rods two, is installed to further limit the wire rope, preventing violent swaying of the workboat due to wind, waves, etc., thus further improving the workboat's stability.
