DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions in the present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] Refer to Figures 1-4, A marine windlass automatic locking device, including a bottom plate 1 and an emergency unlocking mechanism. Both ends of the bottom plate 1 are fixedly connected with mounting plates 2. A cable roller 3 is rotatably connected between the upper parts of the two mounting plates 2. One end of the cable roller 3 is fixedly connected with a rotating rod 4. The rotating rod 4 is rotatably connected through the mounting plate 2. The outer end of the rotating rod 4 is fixedly connected with a chuck 5. Four card slots 6 are arranged in a circumferential array on the outer edge of the chuck 5. The part between every two card slots 6 on the chuck 5 is an arc with continuously decreasing diameter, that is, both sides of the opening of each card slot 6 are one high and one low. The bottom end of the mounting plate 2 close to the chuck 5 is fixedly connected with a sliding seat 14. Both sides inside the sliding seat 14 are provided with sliding grooves 15. A base 7 is slidably connected inside the sliding seat 14 through the sliding grooves 15. The upper surface of the base 7 is fixedly connected with a hydraulic cylinder 8. The top end of the hydraulic cylinder 8 is slidably connected with a hydraulic rod 9. The top end of the hydraulic rod 9 is fixedly connected with a fixed clamping block 10. The fixed clamping block 10 is movably clamped with the card slot 6. When the chuck 5 rotates, the fixed clamping block 10 slides from the low side to the high side of the card slot 6 and inserts into the card slot 6 to stop the rotation of the chuck 5. The connection parts between the fixed clamping block 10 and the card slot 6 are all rounded corners, ensuring that the connection between the fixed clamping block 10 and the card slot 6 is smoother, reducing friction and wear, enhancing the structural stability. The upper end of the fixed clamping block 10 is a U-shaped block matching the card slot 6. The U-shaped block is slidably connected with the inner surface of the card slot 6. The non-clamping part of the fixed clamping block 10 outside the card slot 6 is thicker than the clamping part inside the card slot 6, making the fixed clamping block 10 more durable, more resistant to impact, not easily damaged, and having a longer service life;

[0023] The device drives the hydraulic mechanism to make the fixed clamping block 10 clamped with the card slot 6 on the chuck 5, so that the chuck 5 is fixed to stop rotating, thereby realizing the self-locking of the cable roller 3. This self-locking mechanism has a simple structure, is easy to install and maintain. It not only reduces the material cost and manufacturing cost, but also saves the time and labor cost in the installation and maintenance process, and improves the overall reliability of the device;

[0024] The emergency unlocking mechanism includes a sliding seat 14 and a limiting plate 16 movably clamped on the sliding seat 14. The limiting plate 16 is attached to one side of the outer surface of the base 7 to limit the position of the base 7 to ensure the stability of the hydraulic mechanism. The top of the limiting plate 16 is fixedly connected with a first pull rod 17 for pulling out the limiting plate 16 during emergency unlocking. Both ends of the side of the base 7 attached to the limiting plate 16 are fixedly connected with fixed rods 18. A connecting rod 19 is fixedly connected between the two fixed rods 18. The top of the connecting rod 19 is fixedly connected with a second pull rod 20 for pulling the base 7 during emergency unlocking, thereby driving the fixed clamping block 10 on the hydraulic rod 9 to disengage from the card slot 6 to achieve emergency unlocking. By setting the emergency unlocking mechanism, in case of an emergency, even if the hydraulic mechanism fails, it can be emergently unlocked to ensure the normal operation of the windlass;

[0025] A support plate 11 is fixedly connected to the outer side of a mounting plate 2 away from the chuck 5, a motor 12 is fixedly connected to the support plate 11, an output shaft of the motor 12 is fixedly connected to one end of the cable winding roller 3, two mounting feet 13 are fixedly connected to the outer bottom ends of the two mounting plates 2, the mounting feet 13 are provided with fixing holes, the mounting feet 13 are connected to the deck through the fixing holes, so that the device is fixed on the deck of the ship.

[0026] The functional principle of the utility model can be explained through the following operation modes:

[0027] When in use, the motor 12 is started, and the motor 12 drives the cable winding roller 3 to rotate to release the anchor chain, and the cable winding roller 3 drives the chuck 5 to rotate at the same time. When the anchor chain is placed in a suitable position, the hydraulic mechanism is started at this time, and the hydraulic cylinder 8 drives the hydraulic rod 9 to move upward, driving the fixed clamping block 10 at the top of the hydraulic rod 9 to move upward, and constantly approach the chuck 5 until it contacts the outer edge of the chuck 5. Since the chuck 5 is rotating, relatively, the fixed clamping block 10 slides from the low side of a certain slot 6 along the outer contour of the chuck 5 to the high side and is inserted into the slot 6, so that the chuck 5 stops rotating, and then the cable winding roller 3 stops rotating, realizing the self-locking of the cable winding roller 3. The self-locking mechanism has a simple structure and is easy to install and maintain, which not only reduces the material cost and manufacturing cost, but also saves time and labor costs during installation and maintenance, and improves the overall reliability of the device;

[0028] When it is necessary to release the self-locking of the cable winding roller 3, it is only necessary to drive the hydraulic mechanism to make the hydraulic rod 9 drive the fixed block 10 to move downward and disengage from the slot 6 on the chuck 5. If the hydraulic mechanism fails, the limit plate 16 can be pulled out first, and then the base 7 can be pulled to drive the fixed block 10 on the hydraulic rod 9 to disengage from the slot 6 to achieve emergency unlocking. By setting up an emergency unlocking mechanism, in an emergency, even if the hydraulic mechanism fails, emergency unlocking can be achieved to ensure the normal operation of the anchor machine.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
