Description

Technical Field

[0001] This utility model relates to the field of marine equipment technology, specifically a marine protective mooring device. Background Technology

[0002] When a ship is berthed or anchored at a dock, the mooring device is the core component connecting the ship to the dock and anchor. Its performance is directly related to the stability of the ship's berthing and the safety of the operation. The ship's mooring device is exposed to the marine or dock environment for a long time and must continuously withstand the tension of the ship's cables, the impact of waves, and the alternating loads brought about by the rise and fall of tides.

[0003] Existing mooring systems, which use winches to wind and pull cables to bring ships ashore and maintain berthing stability, are susceptible to interference from various external forces, such as the impact of wind and waves in the dock area, water flow disturbances caused by passing ships, and water level changes due to tidal fluctuations. These external forces cause the ship to sway laterally or longitudinally, which in turn transmits alternating tension to the mooring winch through the cables. Due to the lack of protective and stabilizing structures, when the instantaneous tension caused by the ship's swaying exceeds the winch's pulling force, the winch's braking components are prone to overload, resulting in weakened or even failed braking effects. This causes the winch to lose tension, and the previously wound cable will unexpectedly unwind, reducing the cable tension and making it unable to continue providing stable traction restraint to the ship.

[0004] Therefore, those skilled in the art have provided a marine protective mooring device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a marine protective mooring device to solve the existing problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A marine protective mooring device includes: a winch base, a winch rotatably mounted in the winch base, a brake disc mounted on the right side of the winch, a support mounted below the brake disc, a brake pad pressure ring provided at the upper end of the brake disc, a through tube fixedly mounted on the top of the brake pad pressure ring, a pressure seat mounted on the outer side of the brake pad pressure ring, a rotating rod rotatably mounted through the upper end of the pressure seat, a reversing gearbox mounted on the left side of the winch, and a power failure braking motor for driving the winch mounted on the top of the reversing gearbox.

[0007] As a further improvement of this utility model: the support and the brake pad pressure ring are rotatably connected, and the inner wall of the brake pad pressure ring is in contact with the outer surface of the brake disc.

[0008] As a further improvement of this utility model: the rotating rod and the through-tube are connected by a thread, and the rotating rod and the pressure seat are connected by a rotating structure.

[0009] As a further improvement of this utility model: the power failure braking motor is connected to one end of the winch via a commutator gearbox.

[0010] As a further embodiment of this utility model: a top seat is fixedly installed above the winch base, the top seat has a slot, a clamping roller is fitted inside the slot, and a clamping plate is provided on the outside of the slot.

[0011] As a further improvement of this utility model: the slots are equidistantly opened along the surface of the top seat, and the internal structure of the slots matches the dimensions of the two ends of the clamping roller.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By combining the power failure braking motor and the auxiliary braking structure, the braking capacity of the winch is greatly enhanced. When the ship sways due to external forces such as wind, waves, currents, and tides, causing alternating tension to be transmitted to the winch, if the instantaneous tension is large, the pressure seat can be moved by rotating the rotating rod, so that the brake pad pressure ring is tightly attached to the brake disc. The friction between the two forms an auxiliary brake, which avoids the winch braking components from failing due to overload, thereby reducing the occurrence of winch slippage and ensuring that the pulling rope always maintains a stable tension, providing continuous and reliable pulling constraints for the ship. Using a power-off braking motor as the power source, and taking advantage of the characteristics of releasing the brake when the power is on and automatically braking when the power is off, the braking device of the power-off braking motor will immediately and automatically clamp the rotor in the event of an unexpected power outage, preventing the winch from releasing the rope unexpectedly due to loss of power and braking. At the same time, the brake pad pressure ring on the brake disc can further enhance the braking effect, forming a double emergency protection. Even in the event of a power outage, it can ensure that the winch remains in a braking state, preventing the ship from leaving the shore due to rope release, and greatly improving the safety of the mooring device.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 This utility model provides a marine protective mooring device, including: a winch base 1, a top seat 4 fixedly installed on the top of the winch base 1, a slot 12 opened on the top seat 4, a clamping roller 14 fitted inside the slot 12, a clamping plate 13 provided on the outside of the slot 12, the slot 12 is opened at equal intervals along the surface of the top seat 4, and the internal structure of the slot 12 matches the structural dimensions of the two ends of the clamping roller 14.

[0020] Specifically, by using the slot 12, the spacing between the clamping rollers 14 is adjusted, thereby enabling the clamping rollers 14 to clamp the pulling rope, increasing the friction at the output end of the pulling rope and improving the stability of the winch 2. The clamping plate 13 is staggered with the slot 12, pressing the end of the clamping roller 14 with the clamping plate 13, and the screws fix the clamping plate 13 to the outside of the slot 12 of the top seat 4, pressing down on the clamping roller 14 and maintaining the stability of the clamping roller 14.

[0021] A winch 2 is rotatably mounted in the winch base 1. A brake disc 3 is mounted on the right side of the winch 2. A support 11 is mounted below the brake disc 3. A brake pad pressure ring 7 is provided at the upper end of the brake disc 3. A through tube 8 is fixedly mounted on the top of the brake pad pressure ring 7. A pressure seat 9 is mounted on the outside of the brake pad pressure ring 7. A rotating rod 10 is rotatably mounted inside the upper end of the pressure seat 9. The support 11 and the brake pad pressure ring 7 are rotatably connected. The inner wall of the brake pad pressure ring 7 is in contact with the outer surface of the brake disc 3. The rotating rod 10 and the through tube 8 are threadedly connected. The rotating rod 10 and the pressure seat 9 are rotatable. Specifically, by utilizing the threaded connection between one end of the rotating rod 10 and the through pipe 8, rotating the rotating rod 10 causes it to move inward. As the rotating rod 10 moves inward, it also moves the pressure seat 9 inward. The inner side of the pressure seat 9 is connected to one end of the brake pad pressure ring 7, thereby pushing the brake pad pressure ring 7 close to the outer surface of the brake disc 3 until the brake pad pressure ring 7 is pressed tightly against the outer side of the brake disc 3. The friction between the brake pad pressure ring 7 and the brake disc 3 assists in achieving the braking effect of the winch 2, preventing the rope from slipping out under external force. A reversing gearbox 5 is installed on the left side of the winch 2, and a power failure brake motor 6 for driving is installed on the top of the reversing gearbox 5. The power failure brake motor 6 is connected to one end of the winch 2 through the reversing gearbox 5. Specifically, the reversing gearbox 5 is used to drive the winch 2 to rotate via the power failure braking motor 6. The reversing gearbox 5 contains a transmission device with multiple sets of gears, such as driving gears, driven gears, and idler gears. Through the meshing transmission between the gears, the power of the input shaft is transmitted to the output shaft. By switching different gear combinations, the direction of the driving force transmitted by the power failure braking motor 6 is changed, thereby driving the winch 2 to rotate and realize the winding and unwinding of the traction rope, thus helping the ship to dock. When the power failure braking motor 6 is powered on, the braking device is released. When the motor is powered off, the braking device automatically clamps the rotor, which can effectively prevent the winch from releasing the rope due to lack of braking when there is an accidental power failure. The brake pad pressure ring 7 on the brake disc 3 further improves the braking effect.

[0022] Working Principle: When using this invention, firstly, the winch base 1 of the mooring device is securely installed in the designated position. Then, the pull rope is passed through the gap between the clamping rollers 14. By adjusting the position of the clamping rollers 14 in the slot 12, the clamping rollers 14 can tightly clamp the pull rope, increasing the friction between the pull rope and the device and ensuring the stability of subsequent operations. When the ship needs to dock for mooring operations, the power-off brake motor 6 is activated. After the power-off brake motor 6 is powered on, the braking device is released, and power is transmitted to the winch 2 through the reversing gearbox 5. Multiple sets of gears in the reversing gearbox 5 mesh and drive each other. Different gear combinations are switched according to actual needs to change the direction of power transmission, driving the winch 2 to rotate, thereby realizing the operation of raising and lowering the pull rope and assisting in the operation. When a vessel docks smoothly, if enhanced braking is required during mooring, the rotating rod 10 can be rotated. Since the rotating rod 10 is threadedly connected to the through pipe 8, rotating the rotating rod 10 will move inward, thereby causing the pressure seat 9 to move inward. The pressure seat 9 pushes the brake pad pressure ring 7, making the brake pad pressure ring 7 tightly fit against the outer surface of the brake disc 3. The friction between the brake pad pressure ring 7 and the brake disc 3 assists in braking the winch 2, effectively preventing the rope from being released due to external forces. In the event of an unexpected power outage, the braking device of the power-off braking motor 6 will automatically clamp the rotor to prevent the winch from releasing the rope due to lack of braking. At the same time, the brake pad pressure ring 7 on the brake disc 3 can further enhance the braking effect, ensuring the safety and stability of the vessel's mooring.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
