DETAILED DESCRIPTION

[0027] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0028] like Figures 1 to 3 As shown, the following preferred technical solutions are provided:

[0029] A marine winch includes a winch body 1, mounted with a rope-laying mechanism 2 for guiding the arrangement and winding of steel cables, and a sweeping mechanism 3 for surrounding and cleaning the cables. The rope-laying mechanism 2 is mounted on the winch body 1 via a fixed frame 4 and faces the cable drum of the winch body 1. The sweeping mechanism 3 is mounted on the rope-laying mechanism 2 and faces the rope-laying mechanism 2. The rope-laying mechanism 2 includes a guide wheel assembly 21 and a reciprocating follower assembly 22. The reciprocating follower assembly 22 is mounted on the fixed frame 4 via a connecting plate 5, with the guide wheel assembly 21 and the connecting plate 5 being slidably connected. The sweeping mechanism 3 is mounted on the reciprocating follower assembly 22 via an outer ring seat 31 and is slidably connected to the guide wheel assembly 21. The fixed frame 4 is also provided with two sets of sponge rollers 6 for wiping water stains on the surface of the steel cables.

[0030] Specifically, in order to solve the technical problem that the steel cable of the ship winch is easily wrapped with water plants and other debris attached to the steel cable during use, thereby affecting the winding of the steel cable, and if it is not effectively cleaned, the attached water plants or debris will rot and corrode the steel cable, the present invention installs a rope arrangement mechanism 2 for guiding the arrangement and winding of the steel cable and a sweeping mechanism 3 that surrounds the steel cable and cleans the steel cable at the roller of the winch body 1, thereby achieving surrounding cleaning of the steel cable while guiding and arranging the steel cable, and utilizing the reciprocating follower assembly 22 to drive the guide wheel group 21 to constrain and guide the steel cable during the winding and unwinding process, so that it can be wound and released in an orderly manner to avoid the entanglement and jamming of the steel cable, and the surface of the steel cable is cleaned by the sweeping mechanism 3 while the steel cable is winding and releasing, and the attached water plants and the like are removed.

[0031] like Figures 1 to 8 As shown, the following preferred technical solutions are provided:

[0032] The reciprocating follower assembly 22 includes a reciprocating frame 221, a reciprocating roller 222 and a driving module 223. The reciprocating frame 221 and the driving module 223 are both fixedly mounted on the connecting plate 5. The reciprocating roller 222 is rotatably mounted on the reciprocating frame 221 and is transmission-connected to the driving module 223. The circular sweeping mechanism 3 is mounted on the reciprocating frame 221 through a follower seat 224, and the follower seat 224 is slidingly connected to the reciprocating roller 222.

[0033] Two spiral grooves 225 with opposite rotation directions are provided on the reciprocating roller 222. The follower seat 224 and the spiral groove 225 are slidingly connected via a connector 226. The connector 226 and the follower seat 224 are rotationally connected. The follower seat 224 and the reciprocating frame 221 are slidingly connected via a guide rod group 227. The guide rod group 227 is installed on the reciprocating frame 221. The ring sweeping mechanism 3 is connected to the follower seat 224 via an outer ring seat 31.

[0034] Specifically, in order to solve the technical problem that the circular sweeping mechanism 3 and the guide wheel group 21 can move accordingly with the winding and unwinding of the steel cable, the present invention drives the reciprocating roller 222 to rotate through the driving module 223, and utilizes the spiral groove 225 on the reciprocating roller 222 to realize the rotation of the reciprocating roller 222 while driving the connecting head 226 and the follower seat 224 slidably connected thereto to move back and forth along the guide rod group 227, thereby realizing the synchronous movement of the circular sweeping mechanism 3 and the guide wheel group 21 and the steel cable, completing the arrangement and cleaning of the ropes.

[0035] like Figures 3 to 7 As shown, the following preferred technical solutions are provided:

[0036] The guide wheel group 21 includes two constraint wheels 211 and a guide frame 212. The constraint wheels 211 abut against each other and are rotatably connected to the guide frame 212. The two constraint wheels 211 abut against each other to form a constraint circle. The steel cable passes through the constraint circle. The guide frame 212 is slidably connected to the outer ring seat 31, and the guide frame 212 is slidably connected to the connecting plate 5.

[0037] The guide frame 212 and the outer ring seat 31 are connected by a sliding rod 213, and the sliding rod 213 is fixed at the four corners of the guide seat. A sliding groove 311 is provided on the outer ring seat 31, and the sliding rod 213 and the sliding groove 311 are slidingly connected. The guide seat and the connecting plate 5 are slidingly connected by a guide groove 214, and the guide groove 214 is provided on the guide frame 212.

[0038] Specifically, in order to solve the technical problem that the guide wheel group 21 can move synchronously with the sweeping mechanism 3 and constrain and guide the steel cable, the present invention uses two constraining wheels 211 to form a constraining circle, so that the steel cable passes through the constraining circle. When the steel cable is wound, the two constraining wheels 211 and the guide frame 212 ensure that the steel cable is facing the sweeping mechanism 3, and when the reciprocating follower assembly 22 moves, the connection with the outer ring seat 31 is achieved through the sliding rod 213 and the sliding groove 311, and the sliding between the guide groove 214 and the connecting plate 5 is used to make the guide seat and the outer ring seat 31 move synchronously along the guide rod group 227, thereby realizing the synchronous guiding arrangement when the steel cable is wound.

[0039] like Figure 5 and 8 As shown, the following preferred technical solutions are provided:

[0040] The circular sweeping mechanism 3 includes an arc-shaped brush 32, a movable brush seat 33 and an inner ring seat 34. The arc-shaped brush 32 is slidably clamped on the movable brush seat 33. The movable brush seat 33 and the inner ring seat 34 are connected by an adjustment component 35. The inner ring seat 34 can be rotatably installed on the outer ring seat 31. The movable brush seat 33 and the adjustment component 35 are connected by a quick connector 36.

[0041] The adjustment assembly 35 includes an adjusting screw 351, multiple groups of rotating rods 352 and a rod sleeve 353. One end of the adjusting screw 351 is hinged to the outer ring seat 31 and the other end is hinged to the inner ring seat 34. The rotating rods 352 are distributed in an array along the circumferential direction of the outer ring seat 31, and one end of the rotating rod 352 is hinged to the outer ring seat 31, and the other end passes through the corresponding rod sleeve 353 to be connected to the quick connector 36. The rod sleeve 353 is distributed in an array along the circumferential direction of the inner ring seat 34 and is hinged to the inner ring seat 34.

[0042] Specifically, in order to solve the technical problem that the sweeping mechanism 3 can surround the steel cable and be close to the steel cable for cleaning, the present invention uses an adjustment component 35 to enable multiple groups of arc-shaped brushes 32 to form a cleaning sweeping circle, and each arc-shaped brush 32 is close to the steel cable. The adjusting screw 351 is rotated by a wrench, so that the adjusting screw 351 drives the inner ring seat 34 to rotate, and then the inner ring seat 34 is used to drive the corresponding rod sleeve 353 to move, so that each rotating rod 352 rotates. When each rotating rod 352 rotates toward the center of the inner ring seat 34, the arc-shaped brushes 32 on the rotating rod 352 will approach each other and form a sweeping circle to surround the steel cable for cleaning.

[0043] An air nozzle for blowing air onto the steel cable can be provided on the inner ring seat 34 to achieve blowing and air drying of the steel cable, thereby completing preliminary cleaning of the steel cable.

[0044] like Figure 8 As shown, the following preferred technical solutions are provided:

[0045] The quick connector 36 is hinged to the corresponding movable brush holder 33, and is slidably engaged with the corresponding rotating rod 352. A rectangular hole and a pin hole are respectively provided at both ends of the quick connector 36. The rotating rod 352 is inserted into the large rectangular hole of the quick connector 36. The rotating rod 352 and the pin hole of the quick connector 36 are connected by a pin head 361, and the pin head 361 is fixedly mounted on the corresponding rotating rod 352.

[0046] A spring pin 362 is installed at the pin hole of the quick connector 36, and the spring pin 362 can be pinned to the pin head 361. A pin ring 363 is slidably sleeved on the pin head 361. Both sides of the pin ring 363 are conical surfaces. A hemispherical head 364 is provided at the end of the pin head 361 away from the rotating rod 352, and a conical groove 365 that matches the conical surface of the pin ring 363 is provided on the side of the hemispherical head 364 close to the pin ring 363.

[0047] Specifically, in order to solve the technical problem of quick installation and replacement of the curved brush 32 and the movable brush holder 33, the present invention quickly pins the movable brush holder 33 and the curved brush 32 connected thereto on the rotating rod 352 through the quick connector 36. First, the rectangular hole of the quick connector 36 is docked with the rotating rod 352, and then the quick connector 36 is further pushed so that the pin head 361 is inserted into the pin hole of the quick connector 36. The spherical surface of the hemispherical head 364 presses the spring pin 362, so that the spring pin 362 retracts. When the hemispherical head 364 passes through the position of the spring pin 362, the spring pin 362 is reset, and the latch is between the pin ring 363 and the hemispherical head 364, thereby realizing the whole quick connector 3 6 is pinned to the rotating rod 352; when the curved brush 32 needs to be disassembled and replaced, the quick connector 36 is further pushed so that the spring pin 362 abuts against the front conical surface of the pin ring 363 to retract the spring pin 362. After continuing to push the quick connector 36, the spring pin 362 is reset. Then the quick connector 36 is pulled back. The spring pin 362 extends out and begins to abut against the conical surface on the other side of the pin ring 363, and the pin ring 363 is pushed to the hemispherical head 364, so that the pin ring 363 matches the conical groove 365 of the hemispherical head 364. Then the quick connector 36 is continued to be pulled. The pin ring 363 and the hemispherical head 364 retract the spring pin 362 again, thereby separating the quick connector 36 from the pin head 361.
