Technical Field

[0001] The utility model belongs to the technical field of ship parts, and more specifically relates to a ship anchor cable stall brake. Background Art

[0002] Ships frequently deploy and retract anchor cables. This is accomplished using windlasses. However, existing technologies often fail to protect against anchor cable stalls, as the heavy weight of the anchor cable often leads to increased speed during deployment, increasing the risk of a stall on the deck and causing significant economic losses.

[0003] There is a technology in the prior art named "tension control device for anchor rope" and publication number "WO2011139160A1", which relates to a tension control device (20) for a large diameter anchor rope (10), which is wound on a winch drum (4) on a ship (6), and is characterized by having a first and a second intermediate link arm (24), which can be rotatably adjusted on a first inner link arm and a second intermediate pulley (25) is arranged near the outer side of the second link arm, the outer end of the second intermediate pulley link arm, and a third outer link arm (26), which can be rotatably adjusted on the second intermediate link arm and a third pulley (27) is arranged near the outer end of the third outer link arm, wherein the second intermediate link arm is adjusted in angle by using a first actuator (24a) arranged between the first inner link arm and the second link arm, wherein the relative angle of the third outer link arm to the second intermediate link arm is controlled by a second actuator (26a). Each pulley includes a brake (23m, 25m, 27m).

[0004] However, this technology does not involve the technical problems and technical solutions of the present application. Utility Model Content

[0005] The technical problem to be solved by the utility model is: to address the deficiencies of the existing technology, to provide a ship anchor cable stall brake which has a simple structure and can reliably achieve braking when a stall problem occurs during anchor cable release, thereby playing a protective role and eliminating the safety hazards caused by anchor cable stall.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is:

[0007] The utility model is a ship anchor cable stall brake. An anchor cable channel is arranged on a base. A track arranged obliquely from top to bottom is arranged on the base. A gear is movably connected to a connecting seat. The connecting seat is movably connected to the track. A limiter is arranged between the connecting seat and the track. The distance between the upper end of the track and the anchor cable channel is greater than the distance between the lower end of the track and the anchor cable channel.

[0008] The base comprises a first base component and a second base component, and an anchor cable channel is formed between the first base component and the second base component.

[0009] The track comprises a first track and a second track, wherein the first track is arranged on the first component of the base, and the second track is arranged on the second component of the base.

[0010] The gears include a first gear and a second gear, the first gear is arranged on a first track, and the second gear is arranged on a second track.

[0011] The first track and the second track are in a V-shaped structure.

[0012] The limiter includes a first limiter and a second limiter, and the connecting seat includes a first connecting seat and a second connecting seat.

[0013] A first limiter is provided between the first connecting seat and the first track, and a second limiter is provided between the second connecting seat and the second track.

[0014] A trumpet-shaped channel entrance is provided on the upper portion of the anchor cable channel between the first base component and the second base component.

[0015] The technical solution of this utility model is adopted, and the working principle and beneficial effects are as follows:

[0016] The ship anchor cable stall brake described in the present invention has an anchor cable channel provided on the base during structural setting, and the anchor cable channel is a channel for releasing and retracting the anchor cable. A track arranged obliquely from top to bottom is provided on the base, and the gear is movably connected to the connecting seat, and the connecting seat is movably connected to the track, so that on the one hand the gear can rotate relative to the connecting seat, and on the other hand the connecting seat can move up and down relative to the track. A limiter is provided between the connecting seat and the track, and the function of the limiter is to limit the position of the connecting seat on the track. When the anchor cable is released normally, the force applied by the limiter is applied to the connecting seat to ensure that the connecting seat does not slide downward relative to the track. At this time, the gear can only rotate and will not affect the normal release of the anchor cable. If the anchor cable is released too quickly and stalls, the force generated by the anchor cable is greater than the force applied by the stopper, and the stopper cannot limit the connector. The connector moves downward along the track, allowing the gear to move downward. However, the distance between the upper end of the track and the anchor cable channel is greater than the distance between the lower end of the track and the anchor cable channel. In other words, as the gear moves downward, it moves closer to the anchor cable channel. After the gear moves downward to a certain extent, it clamps the anchor cable, applying a braking force to the anchor cable, preventing further release and stopping the release of the anchor cable. This locks the anchor cable when it stalls, eliminating the hidden dangers of anchor cable stall. The anchor cable is driven upward by the windlass, and the upward movement of the anchor cable drives the gear upward, which is controlled by the stopper again. The anchor cable is then released again, and normal operation can be resumed. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following is a detailed description of the embodiments of the present invention, such as the shapes, structures, positions and connections of the various components involved, the functions and working principles of the various components, etc., by referring to the accompanying drawings.

[0021] As attached Figure 1As shown, the utility model is a ship anchor cable stall brake, an anchor cable channel 2 is provided on the base 1, a track 3 arranged obliquely from top to bottom is provided on the base 1, a gear 4 is movably connected to the connecting seat, the connecting seat is movably connected to the track 3, a limiter 10 is provided between the connecting seat and the track 3, and the distance between the upper end of the track 3 and the anchor cable channel 2 is greater than the distance between the lower end of the track 3 and the anchor cable channel 2. The above structure proposes an improved technical solution to the deficiencies in the prior art. When the structure is set up, an anchor cable channel 2 is provided on the base 1, and the anchor cable channel 2 is a channel for releasing and retracting the anchor cable 7. A track 3 arranged obliquely from top to bottom is provided on the base 1, a gear 4 is movably connected to the connecting seat, and the connecting seat is movably connected to the track 3, so that, on the one hand, the gear 4 can rotate relative to the connecting seat, and on the other hand, the connecting seat can move up and down relative to the track 3. A limiter 10 is provided between the connecting seat and the track 3. The function of the limiter 10 is to limit the position of the connecting seat on the track 3. When the anchor cable 7 is released normally, the force exerted by the limiter 7 is applied to the connecting seat, ensuring that the connecting seat does not slide downward relative to the track 3. At this time, the gear 4 can only rotate and will not affect the normal release of the anchor cable. However, if the anchor cable 7 is released too fast and stalls, the force generated by the anchor cable 7 is large. When the force generated by the anchor cable 7 is greater than the force exerted by the limiter 10, the limiter 10 cannot limit the connecting seat. At this time, the connecting seat moves downward along the track 3, and the gear 4 can move downward. However, the distance between the upper end of the track 3 and the anchor cable channel 2 is greater than the distance between the lower end of the track 3 and the anchor cable channel 2. That is, during the downward movement of the gear 4, it moves toward the anchor cable channel 2. After the gear 4 moves downward to a certain extent, the gear 4 clamps the anchor cable 7, forming a braking force on the anchor cable, preventing the anchor cable 7 from continuing to be released, and achieving a stop in the release of the anchor cable 7. In this way, the anchor cable 7 is locked when it stalls, eliminating the potential safety hazard caused by the anchor cable 7 stalling. The anchor cable 7 is driven upward by the windlass, and the upward movement of the anchor cable 7 drives the gear 4 upward, which is then controlled by the limiter 10 again, and then the anchor cable 7 is re-released, allowing normal operation to resume. The ship anchor cable stall brake described in the utility model has a simple structure and reliably brakes when the anchor cable stalls during release, providing protection and eliminating the potential safety hazard caused by the anchor cable stall.

[0022] The base 1 includes a first base assembly 5 and a second base assembly 6, with an anchor cable passage 2 formed between the first base assembly 5 and the second base assembly 6. In the above structure, the first base assembly 5 and the second base assembly 6 are symmetrically arranged to form an anchor cable passage. The anchor cable passage is used for the passage of the anchor cable. When the anchor cable is released, the track 3, gear 4, and limiter 10 are arranged near the anchor cable passage to reliably prevent the anchor cable from stalling during release.

[0023] The track 3 comprises a first track 8 and a second track 9. The first track 8 is mounted on the first base component 5, while the second track 9 is mounted on the second base component 6. The first and second tracks 8 and 9 are symmetrically arranged, with each track corresponding to a connecting seat, each connecting seat corresponding to a gear. Limiters are used to limit the position of the connecting seat and the corresponding track. When an external force exceeds the force applied by the limiter, the connecting seat overcomes the resistance and moves downward along the track.

[0024] The gear 4 includes a first gear 11 and a second gear 12. The first gear 11 is arranged on the first track 8, and the second gear 12 is arranged on the second track 9. The first track 8 and the second track 9 are V-shaped. In the above structure, the first gear 11 and the second gear 12 are symmetrically arranged. As the first track 8 and the second track 9 move downward, the first gear 11 and the second gear 12 actually approach each other, and the distance between them gradually decreases. When the distance is less than the width of the anchor cable, the anchor cable can be limited, preventing the anchor cable from being further released, effectively solving the problem of anchor cable failure.

[0025] The limiter 10 includes a first limiter 13 and a second limiter 14, and the connecting base includes a first connecting base and a second connecting base. The first limiter 13 is set between the first connecting base and the first track 8, and the second limiter 14 is set between the second connecting base and the second track 9. In the above structure, the limiter is a mature product in the existing technology and is not the focus of improvement. The simplest limiter can be a spring that can apply external force between the connecting base and the track.

[0026] A trumpet-shaped channel entrance 15 is provided on the upper portion of the anchor cable channel 2 between the first base component 5 and the second base component 6. With the above structure, the channel entrance facilitates the passage of the anchor cable.

[0027] The ship anchor cable stall brake described in the present invention is provided with an anchor cable channel 2 on the base 1, and the anchor cable channel 2 is a channel for releasing and retrieving the anchor cable 7. A track 3 arranged obliquely from top to bottom is provided on the base 1, and the gear 4 is movably connected to the connecting seat, and the connecting seat is movably connected to the track 3, so that, on the one hand, the gear 4 can rotate relative to the connecting seat, and on the other hand, the connecting seat can move up and down relative to the track 3. A limiter 10 is provided between the connecting seat and the track 3, and the function of the limiter 10 is to limit the position of the connecting seat on the track 3. When the anchor cable 7 is released normally, the force applied by the limiter 7 is applied to the connecting seat to ensure that the connecting seat does not slide downward relative to the track 3. At this time, the gear 4 can only rotate and will not affect the normal release of the anchor cable. Once the anchor cable 7 is released too quickly and stalls, the force generated by the anchor cable 7 is greater than the force applied by the stopper 10, and the stopper 10 cannot limit the connection base. At this time, the connection base moves downward along the track 3, and the gear 4 can move downward. However, the distance between the upper end of the track 3 and the anchor cable channel 2 is greater than the distance between the lower end of the track 3 and the anchor cable channel 2. That is, during the downward movement of the gear 4, it moves closer to the anchor cable channel 2. After the gear 4 moves downward to a certain extent, it clamps the anchor cable 7, generating a braking force on the anchor cable, preventing the anchor cable 7 from being released further and stopping the anchor cable 7. In this way, the anchor cable 7 is locked when it stalls, eliminating the hidden danger caused by the stall of the anchor cable 7. The anchor cable 7 is driven upward by the windlass, and the upward movement of the anchor cable 7 drives the gear 4 upward again, which is controlled by the stopper 10, and then the anchor cable 7 is released again, and normal operation can be resumed.

[0028] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
