[0001] This utility model relates to the field of ship fittings technology, and more specifically, it relates to a stable mooring winch. Background Technology

[0002] A mooring winch is a winch that can operate effectively when a ship is moored or docked, serving to drift, support, and position the ship, while also adjusting and compensating for deviations caused by vibration with constant tension.

[0019] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0021] Please see Figure 1-4 The present invention provides the following technical solution:

[0022] A stable mooring winch includes a motor 1, a gearbox 2 connected to the output shaft of the motor 1, and a reel 3 connected to the output end of the gearbox 2, forming the main body of the mooring winch. A cable management device 4 is connected to the central shaft of the reel 3, and a tension detector 5 is installed inside the cable management device 4. When the reel 3 rotates, it drives the cable management device 4 to move, thereby driving the cable to move along the reel 3, avoiding tangled winding and facilitating the detection of cable tension. The output shaft of the motor 1 extends out of the gearbox 2, and a braking device 6 is installed on both sides of the output shaft of the motor 1 in the gearbox 2. The braking devices 6 on both sides act synchronously, reducing the intensity of the force on the braking devices 6, while balancing the force on the output shaft of the motor 1 and preventing shaft deformation. The tension detector 5 transmits a signal to a controller 8. The controller 8 controls the braking intensity of the braking devices 6 according to the changes in tension. By controlling the braking intensity of the braking devices 6, the output speed is changed, thereby changing the speed of cable winding and unwinding to maintain constant tension without affecting the output torque of the motor 1, thus ensuring a stable tension on the cable and ensuring the overall stability of the mooring winch function.

[0023] The braking device 6 includes a hub 61 and a hydraulic cylinder 62. The hub 61 is fixed on the output shaft of the motor 1. Two brake pads 63 are connected to the output shaft of the hydraulic cylinder 62. The two brake pads 63 are symmetrically arranged on both sides of the hub 61. The two brake pads 63 can clamp the hub 61 from both sides. The brake pads 63 act directly on the hub 61, which extends the lever arm and reduces the force required on the brake pads 63 during braking. This ensures the braking effect while extending the service life of the device.

[0024] A cooling device 7 is installed on the braking device 6. A temperature sensor is installed on the braking device 6. Both the temperature sensor and the cooling device 7 are connected to the controller 8. The cooling device 7 is controlled by the detected temperature to cool down the braking device 6, which can prevent the braking device 6 from overheating and affecting the braking effect.

[0025] The cooling device 7 includes a water pump 71, the outlet of which is connected to a connecting pipe 72. The other end of the connecting pipe 72 is connected to a plurality of spray nozzles 73. The plurality of spray nozzles 73 are respectively arranged on the side of the brake pad 63 away from the wheel hub 61. The spray liquid only acts on the outside of the brake pad 63, which can cool the brake pad 63 and prevent overheating from affecting the braking effect and service life. The spray liquid will not enter between the brake pad 63 and the wheel hub 61, thus avoiding the liquid from affecting the lubrication of the friction surface and affecting the braking effect.

[0026] Specifically, the input end of the mooring winch gearbox 2 has a high speed and low torque. The brake device 6 is set on both sides of the input end of the gearbox 2, which can easily change the speed of the output end of the gearbox 2. The tension detector 5 can transmit the tension on the cable to the controller 8 in real time. The controller 8 adjusts the braking intensity of the brake device 6 accordingly, thereby realizing the adjustment of the cable winding and unwinding speed of the reel 3, achieving constant tension without affecting the torque at the output end, and providing stable tension for the cable.
