Technical Field

[0001] This utility model relates to the field of pipe winding technology, and in particular to a rapid winding device for marine pipes. Background Technology

[0002] Marine pipelines serve multiple important functions, such as drawing water from nature for firefighting and backup purposes, as well as draining water from the ship's hull. These pipelines are usually quite long and need to be properly stored when not in use to avoid taking up too much space and getting tangled, which requires rapid roll-up and unrolling equipment for marine pipelines.

[0003] Most of the fast winding and unwinding equipment on the market can only quickly wind up a single set of pipes, and it is inconvenient to replace another set of pipe winding and unwinding equipment. This will affect the winding and unwinding efficiency of multiple sets of marine pipes. Therefore, a fast winding and unwinding equipment for marine pipes is needed. Utility Model Content

[0004] The purpose of this invention is to provide a rapid winding and unwinding device for marine pipes, which solves the problem that most existing rapid winding and unwinding devices can only quickly wind up a single set of pipes, and it is inconvenient to replace another set of pipe winding drums, which affects the winding and unwinding efficiency of multiple sets of marine pipes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid winding and unwinding device for marine pipes, comprising a housing, a support frame at the front end of the housing, a first motor fixed to the side wall of the support frame, a first rotating shaft at the rotating end of the first motor, a hollow rotating cylinder fixed to the other end of the first rotating shaft, a threaded groove on the inner wall of the hollow rotating cylinder, a threaded post threadedly connected to the inner side of the threaded groove, a hollow support fixed to the top of the threaded post, a movable plate on one side of the hollow support, a second rotating shaft at the connection between the hollow support and the movable plate, an arc-shaped top plate at the other end of the movable plate, a third rotating shaft at the connection between the movable plate and the arc-shaped top plate, a first slider fixed to the bottom end of the arc-shaped top plate, and a first slide rail on the outer side of the first slider.

[0006] Preferably, a second motor is fixed inside the outer casing. A fourth rotating shaft is provided at the rotating end of the second motor. A gear plate is fixed at the other end of the fourth rotating shaft. A rack plate is meshed with the upper side of the gear plate. A rack cylinder is meshed with the upper side of the rack plate. A connecting column is fixed at one end of the rack plate. A first bearing is provided around the connecting column. A fixing plate is provided around the first bearing. A rotating roller is fixed at the other end of the connecting column. An arc-shaped groove is formed on the side wall of the rotating roller. A cylindrical slider is provided inside the arc-shaped groove. A transmission plate is fixed on the side wall of the cylindrical slider. A movable column is provided at the other end of the transmission plate. A fifth rotating shaft is provided at the connection between the transmission plate and the movable column. A second slider is fixed on the side wall of the movable column. A second slide rail is provided outside the second slider. A second bearing is provided at the connection between the movable column and the rack cylinder. A pipe winding drum is provided on the outside of the arc-shaped top plate.

[0007] Preferably, the hollow drum and the first rotating shaft form a rotating structure through the operation of the first motor, and the hollow drum is connected to the threaded column through the threaded groove, and the threaded column and the hollow support form a fixed structure.

[0008] Preferably, the hollow support column forms a rotating structure with the movable plate via the second rotating shaft, and the movable plate forms a rotating structure with the arc-shaped top plate via the third rotating shaft, and the arc-shaped top plate forms a sliding structure with the first slider and the first slide rail.

[0009] Preferably, the gear plate and the fourth rotating shaft form a rotating structure through the operation of the second motor, the gear plate and the rack plate form a meshing structure, the rack plate and the rack cylinder form a meshing structure, and the rack cylinder forms a rotating structure with the movable column through the second bearing.

[0010] Preferably, the rack plate forms a fixed structure with the rotating roller through the connecting column, and the connecting column forms a rotating structure with the fixed plate through the first bearing. The rotating roller forms a sliding structure with the transmission plate through the arc-shaped sliding groove and the cylindrical slider. The transmission plate forms a rotating structure with the movable column through the fifth rotating shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The rapid winding and unwinding equipment for marine pipes is equipped with threaded grooves and threaded columns. By turning on the first motor, the hollow drum can be driven to rotate. Since the threaded column cannot rotate, the rotation of the hollow drum can cause the threaded column to rise and fall, which indirectly drives the hollow support column to rise and fall. During the rise and fall of the hollow support column, the movable plate can move. The movement of the movable plate can cause the arc-shaped top plate to slide through the first slider and the first slide rail. The relative movement of the four sets of arc-shaped top plates can quickly fix or disassemble the pipe winding drum from the inside, and replace different pipe winding drums. This avoids the situation where most rapid winding and unwinding equipment can only quickly wind and unwind a single set of pipe winding drums, and it is inconvenient to replace another set of pipe winding drums, which would affect the winding and unwinding efficiency of multiple sets of marine pipes.

[0013] 2. The rapid winding and unwinding equipment for marine pipes is equipped with a rotating drum. By turning on the second motor, the gear plate can be driven to rotate. Through the meshing structure of the gear plate and the rack plate, the rotation of the gear plate can cause the rack plate to rotate, which indirectly drives the rotating drum to rotate. The rotation of the rotating drum can cause the cylindrical slider to slide through the arc-shaped slide groove, thereby driving the movable column to move back and forth. Then, through the meshing structure of the rack plate and the rack cylinder, the rotation of the rack plate can cause the rack cylinder to rotate, which drives the support frame and the pipe winding drum to rotate, facilitating the reciprocating movement of the pipe winding drum and the winding and unwinding of the pipe.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the figure, a rapid winding and unwinding device for marine pipes includes a housing 1. A support frame 2 is provided at the front end of the housing 1. A first motor 3 is fixed to the side wall of the support frame 2. A first rotating shaft 4 is provided at the rotating end of the first motor 3. A hollow rotating cylinder 5 is fixed to the other end of the first rotating shaft 4. A threaded groove 6 is provided on the inner wall of the hollow rotating cylinder 5. A threaded post 7 is threadedly connected to the inner side of the threaded groove 6. A hollow support column 8 is fixed to the top of the threaded post 7. A movable plate 10 is provided on one side of the hollow support column 8. A second rotating shaft 9 is provided at the connection between the hollow support column 8 and the movable plate 10. An arc-shaped top plate 12 is provided at the other end of the movable plate 10. A third rotating shaft 11 is provided at the connection between the movable plate 10 and the arc-shaped top plate 12. A first slider 13 is fixed to the bottom end of the arc-shaped top plate 12. A first slide rail 14 is provided on the outer side of the first slider 13.

[0022] The hollow rotating drum 5 and the first rotating shaft 4 form a rotating structure through the operation of the first motor 3. The hollow rotating drum 5 is connected to the threaded column 7 through the threaded groove 6, and the threaded column 7 and the hollow support column 8 form a fixed structure. When the first motor 3 is turned on, the hollow rotating drum 5 can be driven to rotate. Since the threaded column 7 cannot rotate, the rotation of the hollow rotating drum 5 can make the threaded column 7 rise and fall, which indirectly drives the hollow support column 8 to rise and fall.

[0023] The hollow support column 8 forms a rotating structure with the movable plate 10 via the second rotating shaft 9, and the movable plate 10 forms a rotating structure with the arc-shaped top plate 12 via the third rotating shaft 11. The arc-shaped top plate 12 forms a sliding structure with the first slider 13 and the first slide rail 14. During the lifting and lowering process of the hollow support column 8, the movable plate 10 can move, and the movement of the movable plate 10 can cause the arc-shaped top plate 12 to slide via the first slider 13 and the first slide rail 14. The relative movement of the four sets of arc-shaped top plates 12 can quickly fix or disassemble them from the inside of the pipe winding drum 32, and replace different pipe winding drums 32.

[0024] Example 2

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment further illustrates Example 1. A second motor 15 is fixed inside the outer casing 1. A fourth rotating shaft 16 is provided at the rotating end of the second motor 15. A gear plate 17 is fixed at the other end of the fourth rotating shaft 16. A rack plate 18 is meshed with the upper side of the gear plate 17. A rack cylinder 19 is meshed with the upper side of the rack plate 18. A connecting post 20 is fixed at one end of the rack plate 18. A first bearing 21 is provided around the connecting post 20. A fixing plate 22 is provided around the first bearing 21. A rotating roller 2 is fixed at the other end of the connecting post 20. 3. The side wall of the rotating drum 23 is provided with an arc-shaped slide groove 24. A cylindrical slider 25 is provided on the inner side of the arc-shaped slide groove 24. A transmission plate 26 is fixed on the side wall of the cylindrical slider 25. A movable column 28 is provided at the other end of the transmission plate 26. A fifth rotating shaft 27 is provided at the connection between the transmission plate 26 and the movable column 28. A second slider 29 is fixed on the side wall of the movable column 28. A second slide rail 30 is provided on the outer side of the second slider 29. A second bearing 31 is provided at the connection between the movable column 28 and the rack cylinder 19. A pipe winding drum 32 is provided on the outer side of the arc-shaped top plate 12.

[0026] The gear plate 17 and the fourth rotating shaft 16 form a rotating structure through the operation of the second motor 15. The gear plate 17 and the rack plate 18 form a meshing structure, and the rack plate 18 and the rack cylinder 19 form a meshing structure. The rack cylinder 19 forms a rotating structure through the second bearing 31 and the movable column 28. Through the meshing structure of the rack plate 18 and the rack cylinder 19, the rotation of the rack plate 18 can make the rack cylinder 19 rotate, which drives the support frame 2 and the pipe winding drum 32 to rotate, facilitating the reciprocating movement of the pipe winding drum 32 and the winding and unwinding of the pipe.

[0027] The rack plate 18 forms a fixed structure with the rotating roller 23 via the connecting column 20, and the connecting column 20 forms a rotating structure with the fixed plate 22 via the first bearing 21. The rotating roller 23 forms a sliding structure with the transmission plate 26 via the arc-shaped sliding groove 24 and the cylindrical slider 25. The transmission plate 26 forms a rotating structure with the movable column 28 via the fifth rotating shaft 27. When the second motor 15 is turned on, the gear plate 17 can be driven to rotate. Through the meshing structure of the gear plate 17 and the rack plate 18, the rotation of the gear plate 17 can cause the rack plate 18 to rotate, which indirectly drives the rotating roller 23 to rotate. The rotation of the rotating roller 23 can cause the cylindrical slider 25 to slide through the arc-shaped sliding groove 24, thereby driving the movable column 28 to reciprocate.

[0028] Working principle: First, the operator needs to turn on the first motor 3 to drive the hollow drum 5 to rotate. Since the threaded column 7 cannot rotate, the rotation of the hollow drum 5 can cause the threaded column 7 to rise and fall, indirectly driving the hollow support column 8 to rise and fall. During the rising and falling of the hollow support column 8, the movable plate 10 can move. The movement of the movable plate 10 can cause the arc-shaped top plate 12 to slide through the first slider 13 and the first slide rail 14. The relative movement of the four sets of arc-shaped top plates 12 can quickly fix and install them on the inside of the pipe winding drum 32. Then, by turning on the second motor 15, the gear plate 17 can be driven to rotate. The rotation of the gear plate 17 can cause the rack plate 18 to rotate, indirectly driving the rotating drum 23 to rotate. The rotation of the rotating drum 23 can cause the cylindrical slider 25 to slide through the arc-shaped slide groove 24, thereby driving the movable column 28 to move back and forth. The rotation of the rack plate 18 can cause the rack cylinder 19 to rotate, driving the support frame 2 and the pipe winding drum 32 to rotate, facilitating the back and forth movement of the pipe winding drum 32 and the winding and unwinding of the pipe.
