[0018] Beneficial effects of the present invention:

[0019] The present invention provides a marine rope ladder winch and a ship. The marine rope ladder winch includes a winch body, a connection assembly, and a limit assembly. The winch body includes a drum; the connection assembly includes a first lead screw shaft, a first slider screwed to the first lead screw shaft, and a connection plate fixedly provided on the winch body. The first lead screw shaft is drivingly connected to the drum, and the first slider is slidably connected to the connection plate. The drum can drive the first lead screw shaft to rotate, so that the first slider slides axially along the first lead screw shaft and is located on the connection plate; the limit assembly can slide on the connection plate and can be locked to the connection plate, and the first slider can axially abut against the limit assembly along the first lead screw shaft. For this marine rope ladder winch, by drivingly connecting the first lead screw shaft to the drum, the drum drives the first lead screw shaft to rotate, thereby driving the first slider to slide axially along the first lead screw shaft and be located on the connection plate. By slidably arranging the limit assembly on the connection plate, the first slider can slide axially along the first lead screw shaft and abut against the limit assembly. When the first slider axially abuts against the limit assembly along the first lead screw shaft, the first slider stops sliding. At the same time, the drum stops rotating and the drum stops releasing the rope ladder. Specifically, when it is necessary to release a certain length of the rope ladder, first slide and adjust the position of the limit assembly according to the length of the rope ladder to be released by the drum, slide and adjust the limit assembly to an appropriate position and lock the limit assembly to the connection plate, and then control the drum to drive the first lead screw shaft to rotate, thereby driving the first slider to slide axially along the first lead screw shaft. When the first slider axially abuts against the first slider, the length of the rope ladder released by the drum reaches the required length. At this time, the drum stops rotating. It can be understood that by setting the limit assembly to be slidably connected to the connection plate and capable of being locked to the connection plate, the limit assembly can be slidably adjusted axially along the first lead screw shaft to any position, so as to limit the drum to release rope ladders of various lengths, thereby improving the practicability and versatility of the marine rope ladder winch, and the structure is simple.

[0026] To make the technical problems solved by the present invention, the technical solutions adopted, and the achieved technical effects clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0028] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "above the", and "on the" second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the first feature is at a higher horizontal height than the second feature. The first feature being "below", "below the", and "under the" second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the first feature is at a lower horizontal height than the second feature.

[0029] The present invention provides a marine rope ladder winch, such as Figure 1As shown in the figure, the marine rope ladder winch includes a winch body, a connecting component 1 and a limiting component. The winch body includes a drum; the connecting component 1 includes a first lead screw shaft 11, a first slider 12 screwed to the first lead screw shaft 11, and a connecting plate 13 fixedly arranged on the winch body. The first lead screw shaft 11 is drivingly connected to the drum, the first slider 12 is slidably connected to the connecting plate 13, and the drum can drive the first lead screw shaft 11 to rotate so that the first slider 12 slides axially along the first lead screw shaft 11 and is located on the connecting plate 13; the limiting component can slide on the connecting plate 13 and can be locked to the connecting plate 13, and the first slider 12 can axially abut against the limiting structure along the first lead screw shaft 11. For this marine rope ladder winch, by drivingly connecting the first lead screw shaft 11 to the drum, the drum drives the first lead screw shaft 11 to rotate, thereby driving the first slider 12 to slide axially along the first lead screw shaft 11 and be located on the connecting plate 13. By slidably arranging the limiting component on the connecting plate 13, the first slider 12 can slide axially along the first lead screw shaft 11 and abut against the limiting component. When the first slider 12 axially abuts against the limiting component along the first lead screw shaft 11, the first slider 12 stops sliding. At the same time, the drum stops rotating and the drum stops releasing the rope ladder. Specifically, when a certain length of the rope ladder needs to be released, first slide and adjust the position of the limiting component according to the length of the rope ladder that the drum needs to release, slide and adjust the limiting component to an appropriate position and lock the limiting component to the connecting plate 13, and then control the drum to drive the first lead screw shaft 11 to rotate, thereby driving the first slider 12 to slide axially along the first lead screw shaft 11. When the first slider 12 axially abuts against the first slider 12 (should be against the limiting component), the length of the rope ladder released by the drum reaches the required length. At this time, the drum stops rotating. It can be understood that by setting the limiting component to be slidably connected to the connecting plate 13 and can be locked to the connecting plate 13, the limiting component can be slidably adjusted axially along the first lead screw shaft 11 to any position, so that the drum can be limited to release rope ladders of various lengths, thereby improving the practicability and versatility of the marine rope ladder winch, and the structure is simple.

[0030] Specifically, the marine rope ladder winch further includes a second driving member. The second driving member and the first lead screw shaft 11 are connected by a clutch, and the second driving member can drive the drum to rotate, thereby driving the first lead screw shaft 11 to rotate. Among them, the second driving member is a motor.

[0031] Among them, as Figure 1As shown in the figure, the marine rope ladder winch further includes a locking member. The limiting assembly includes a second slider 21. The connecting plate 13 is provided with a first sliding rail 131 along the axial direction of the first lead screw shaft 11. The second slider 21 is slidably located on the first sliding rail 131 and can abut against the first slider 12. The locking member can lock the second slider 21 to the first sliding rail 131. By arranging the second slider 21 to be slidably located on the first sliding rail 131, sliding the second slider 21 along the extending direction of the first sliding rail 131 to the corresponding position, and locking the second slider 21 to the first sliding rail 131 through the locking member, the position of the second slider 21 along the axial direction of the first sliding rail 131 is limited and unchanged. When the first slider 12 abuts against the second slider 21 along the axial direction of the first lead screw shaft 11, the length of the rope ladder released by the drum reaches the required length. At this time, the first slider 12 cannot continue to move along the axial direction of the first lead screw shaft 11, thereby limiting the drum to stop rotating. It can be understood that by arranging the second slider 21 to be slidably connected to the connecting plate 13 and capable of being locked to the first sliding rail 131 through the locking member, the second slider 21 can be adjusted to any position along the extending direction of the first sliding rail 131, so that the drum can be limited to release rope ladders of various lengths, thereby improving the practicability and versatility of the marine rope ladder car, and the structure is simple.

[0032] Specifically, as Figure 1 and Figure 2 shown in the figure, the second slider 21 is provided with a through hole 211. The bottom wall of the first sliding rail 131 is provided with a plurality of threaded holes 1311 at intervals along the axial direction. The locking member passes through the through hole 211 and is screwed into one of the threaded holes 1311. With such an arrangement, the locking member can pass through the through hole 211 and be screwed into any one of the threaded holes 1311. It can be understood that the position of each threaded hole 1311 corresponds to a locking position of the second slider 21 on the first sliding rail 131, and each locking position corresponds to a release length of the rope ladder released by the drum, so that the drum can be limited to release rope ladders of various lengths, thereby improving the practicability and versatility of the marine rope ladder car, and the structure is simple. Preferably, the locking member is a bolt.

[0033] As an alternative solution, the second slider 21 is provided with a clamping protrusion, and the side wall of the first sliding rail 131 is provided with a plurality of clamping grooves at intervals along the axial direction. The clamping protrusion can be clamped into one of the clamping grooves. It can be understood that the position of each clamping groove corresponds to a locking position of the second slider 21 on the first sliding rail 131, and each locking position corresponds to a release length of the rope ladder released by the drum, so that the drum can be limited to release rope ladders of various lengths, thereby improving the practicability and versatility of the marine rope ladder car, and the structure is simple.

[0034] Among them, as Figure 1As shown in the figure, the marine rope ladder winch further includes a first driving member 3. The first driving member 3 is drivingly connected to the second slider 21, and the first driving member 3 can drive the second slider 21 to slide on the first slide rail 131. Thus, the first driving member 3 can drive the second slider 21 to slide on the first slide rail 131, so that the second slider 21 can slide along the extension direction of the first slide rail 131 and stop at any position on the first slide rail 131.

[0035] Specifically, as Figure 1 shown in the figure, the first driving member 3 is a motor. The marine rope ladder winch further includes a second lead screw shaft 22 drivingly connected to the motor. The second slider 21 is screwed onto the second lead screw shaft 22. The motor can drive the second lead screw shaft 22 to rotate, so that the second slider 21 slides on the first slide rail 131. Specifically, the output shaft of the motor is fixedly connected to the second lead screw shaft 22 through a coupling. In this way, it is set to realize that the first driving member 3 drives the second lead screw shaft 22 to rotate, thereby driving the second slider 21 to slide on the first slide rail 131. As an alternative, the first driving member 3 is a cylinder. The output shaft of the cylinder is fixedly connected to the second slider 21, and the output shaft of the cylinder is parallel to the axial direction of the first lead screw shaft 11, thereby driving the second slider 21 to slide along the extension direction of the first slide rail 131 on the first slide rail 131.

[0036] Preferably, as Figure 1 shown in the figure, the second slider 21 slides on the first slide rail 131, and the first slider 12 is located between the second slider 21 and the drum. Thus, it is ensured that the first slider 12 can always effectively press against the second slider 21, thereby effectively limiting the drum from stopping rotating.

[0037] Preferably, at least the part of the second slider 21 in contact with the first slider 12 is provided with an elastic cushion layer. By providing the elastic cushion layer, during the process of the first slider 12 pressing against the second slider 21, the elastic cushion layer can effectively buffer the axial impact force exerted by the first slider 12 on the second slider 21.

[0038] Among them, as Figure 1 shown in the figure, the connecting plate 13 is further provided with a second slide rail 132 extending along the axial direction of the first lead screw shaft 11. The first slider 12 slides on the second slide rail 132. The second driving member drives the first lead screw shaft 11 to rotate, thereby driving the first slider 12 to slide along the extension direction of the second slide rail 132 on the second slide rail 132.

[0039] It can be understood that the central rotation axes of the drum, the first lead screw shaft 11, the second lead screw shaft 22, the extension direction of the first slide rail 131, and the extension direction of the second slide rail 132 are all parallel.

[0040] Specifically, as Figure 1As shown, the connecting plate 13 is L-shaped, and the first slide rail 131 and the second slide rail 132 are respectively located on two mutually perpendicular plate surfaces of the connecting plate 13.

[0041] Among them, as Figure 1 shown, a first limiting surface 133 is provided on the connecting plate 13. The first limiting surface 133 is located at one end of the first slide rail 131 away from the drum, and the second slider 21 can abut against the first limiting surface 133. By providing the first limiting surface 133, the first limiting surface 133 can prevent the second slider 21 from disengaging from the first slide rail 131 when sliding along the first slide rail 131. It can be understood that when the second slider 21 slides to one end of the first slide rail 131 away from the drum, the second slider 21 abuts against the first limiting surface 133.

[0042] Among them, as Figure 1 shown, a second limiting surface 134 is provided on the connecting plate 13. The second limiting surface 134 is located at one end of the second slide rail 132 away from the drum, and the first slider 12 can abut against the second limiting surface 134. By providing the second limiting surface 134, the second limiting surface 134 can prevent the first slider 12 from disengaging from the second slide rail 132 when sliding along the second slide rail 132. It can be understood that when the first slider 12 slides to one end of the second slide rail 132 away from the drum, the first slider 12 abuts against the second limiting surface 134.

[0043] The present invention also provides a ship, which includes the above-mentioned marine rope ladder winch, and also includes a deck. The marine rope ladder winch is fixedly arranged on the deck. Thus, the marine rope ladder winch can be applied to the ship, and the marine rope ladder winch can limit the drum to release rope ladders of various lengths, so as to improve the practicability and versatility of the marine rope ladder winch applied to the ship. Among them, the marine rope ladder winch can be assembled to the ship by a screwed connection method. In other embodiments, the marine rope ladder winch can also be assembled to the ship by welding or other connection methods.

[0044] Among them, the specific structure of the winch body belongs to the prior art and will not be elaborated here.

[0045] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
