Description

Technical Field

[0001] This invention relates to the field of marine cable winch technology, specifically to an auxiliary equipment for a marine armored cable winch. Background Technology

[0002] Ships typically need to be equipped with cable winches for cable extension. Since ships can only be moored on the water in ports and are far from land, long cables are needed to connect to land-based equipment for power supply, data transmission, and other purposes. Therefore, cable winches are required to achieve cable winding and extension.

[0003] A marine towing winch with publication number CN107381392A includes a base. A limiting plate is symmetrically arranged at the upper center of the base. A rotating shaft is rotatably mounted through the center of the limiting plate. A cable drum is located at the center of the rotating shaft. The output end of a reducer is connected to the left end of the rotating shaft. The cable can be wound and unwound through the coordinated arrangement of the rotating shaft, cable drum, reducer, cable motor, and braking device. The order in which the cable winds on the cable drum can be controlled through the coordinated arrangement of a sliding block, support rod, and cable guide ring. The sliding block and cable guide ring can reciprocate between the support plates through the coordinated arrangement of a pressure sensor, support rod, through hole, threaded hole, threaded rod, and small motor. This invention ensures that the cable is wound evenly and neatly on the cable drum by the reciprocating movement of the cable guide ring in front of the cable drum. This guarantees the cable drum's capacity to take in the cable and avoids wear caused by uneven compression friction on the cable, thus increasing the cable's service life.

[0004] However, with existing technology, during the cable retraction process, if a loose cable gets stuck at a certain position, the continuous winding of the drum can cause excessive traction deformation or even breakage. Existing technology can prevent this problem by monitoring the winding tension and achieving timely stopping of the winding rotation. However, the state after stopping is inevitably that the cable is in a taut state. In a taut state, it is difficult to release the stuck position of the free end of the cable. Even if it is released, the taut tension at the time of release will cause the cable to spring back, which can easily cause safety accidents. Summary of the Invention

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

[0020] Please see Figures 1 to 8 The present invention provides a technical solution: A marine armored cable winch auxiliary equipment includes an inner liner assembly 8 and a gear assembly. The inner liner assembly 8 is sleeved inside a drum 4 driven by a drive motor 2 for winding cables. The output end of the drive motor 2 is connected to a rotating shaft 7, and the inner liner assembly 8 is sleeved on the rotating shaft 7. The inner liner assembly 8 includes an inner sleeve 43, an outer arc plate 42, and a middle arc plate 21. Three sets of middle arc plates 21 are arranged in a circumferential array on the outer side of the inner sleeve 43. Outer arc plates 42 are arranged at intervals on the outer side of the middle arc plates 21 and rotate to fit against the inner arc wall of the drum 4. Multiple sets of circumferentially distributed support columns 45 are arranged in the intervals between the inner sleeve 43, the middle arc plate 21, and the outer arc plate 42.

[0021] To increase the winding length, the outer diameter of the drum 4 is usually increased. To reduce the weight of the drum 4 and reduce the driving force for the drum rotation, the drum 4 is designed as a hollow structure. However, the hollow structure will deform due to the winding of the cable. Therefore, the inner lining component 8 is set to support the hollow cavity of the drum 4 and prevent deformation.

[0022] The drive motor 2 is mounted on the base 1, and a pair of spaced-apart side frames 3 are provided on the base 1. The drum 4 is rotatably mounted in the gap between the pair of side frames 3. The rotating shaft 7 passes through the inner cavity of the drum 4. The middle of the inner lining assembly 8 is fixedly sleeved on the rotating shaft 7. The inner sleeve 43 is sleeved on the rotating shaft 7 and fixedly connected to the rotating shaft 7 by a pin 44. The outer side of the inner lining assembly 8 rotates to fit against the inner wall of the drum 4.

[0023] The inner liner assembly 8 and the rotating shaft 7 are fixedly connected by setting the pin 44, and the two ends of the rotating shaft 7 are supported by setting a pair of side frames 3 to ensure the smoothness of the winding rotation.

[0024] Gear rings 20 are fixedly installed at both ends of the inner cavity of the drum 4. A gear assembly for driving the gear rings 20 to mesh and rotate is installed on the inner liner assembly 8. The gear assembly includes a drive gear 25, a linkage gear 26, and a transmission gear 27. The drive gear 25 is fixedly sleeved on the rotating shaft 7. Three sets of stepped connecting rods 41 arranged in a circular array are provided at the end of the inner sleeve 43. The stepped connecting rods 41 slide through the drive gear 25. A fixed shaft 29 is rotatably provided at the end of the inner liner assembly 8. The linkage gear 26 is fixedly sleeved on the fixed shaft 29 and meshes with the drive gear 25. A telescopic shaft 28 is telescopically connected to the end of the fixed shaft 29 near the gear ring 20. A transmission gear 27 that meshes with the gear ring 20 is fixedly sleeved on the telescopic shaft 28.

[0025] By setting a stepped connecting rod 41, the drive gear 25 and the inner liner assembly 8 are fixedly connected. Then, the rotating shaft 7 drives the drive gear 25 and the inner liner assembly 8 to rotate synchronously. During the rotation, the meshing of the drive gear 25 and the linkage gear 26 drives the fixed shaft 29 to rotate, which in turn drives the transmission gear 27 to rotate synchronously. The meshing of the transmission gear 27 and the gear ring 22 drives the drum 4 to rotate, thereby achieving the purpose of winding the cable.

[0026] One end of the fixed shaft 29 is provided with a fixed seat 24, which is fixed to the inner liner assembly 8 with screws. One end of the fixed shaft 29 is rotatably mounted on the fixed seat 24 via a bearing. The other end of the fixed shaft 29 is provided with a stepped telescopic inner cavity 30 and an extension cavity 36. The inner wall of the connecting section between the telescopic inner cavity 30 and the extension cavity 36 is provided with a circumferentially arrayed slot 31. The end of the telescopic shaft 28 is elastically slidably inserted into the telescopic inner cavity 30, and the middle section of the telescopic shaft 28 is arc-shaped. The outer wall is provided with insert strips 35 that mate with slots 31. The end of the telescopic shaft 28 slides into the extension cavity 36. Multiple sets of insert strips 35 are provided with a fixing ring 34 near the end of the transmission gear 27. The fixing ring 34 is fixedly sleeved on the outer wall of the telescopic shaft 28. The port of the telescopic inner cavity 30 is fixedly installed with a limit cover 33 by screws. The telescopic shaft 28 slides through the limit cover 33. A spring 32 is sleeved on the telescopic shaft 28. The spring 32 is pressed between the limit cover 33 and the fixing ring 34.

[0027] The fixed shaft 29 is limited and rotated by the fixed base 24. The telescopic inner cavity 30 and the extension cavity 36 are used to telescopically insert the telescopic shaft 28 at the end of the fixed shaft 29. The limiting cover 33 is used to prevent the telescopic connection from falling off. The spring 32 is used to achieve elastic insertion. Then, under the action of elastic force, the insert 35 is inserted into the slot 31. At this time, the fixed shaft 29 and the telescopic shaft 28 are misaligned, so that the rotation of the fixed shaft 29 can drive the telescopic shaft 28 to rotate.

[0028] The end of the intermediate arc plate 21 is provided with an adjusting inner cavity 22 that is recessed inward. The fixed seat 24 seals the outer port of the adjusting inner cavity 22 by a sealing ring 37. The end of the fixed shaft 29 is provided with a through hole 39 that connects the adjusting inner cavity 22 and the extension cavity 36. A piston 23 is slidably installed in the adjusting inner cavity 22. A push rod 40 that slides along the through hole 39 is rotatably installed on one side of the piston 23 bearing. The push rod 40 is fixed to the end of the telescopic shaft 28. An adjusting air pump 9 that controls the internal pressure of the adjusting inner cavity 22 is provided in the inner liner assembly 8.

[0029] The position of the piston 23 is adjusted by regulating the internal pressure of the inner cavity 22 through the air pump 9. When the internal pressure increases, the piston 23 drives the push rod 40 to squeeze the telescopic shaft 28, which squeezes the spring 32 and drives the insert 35 to separate from the slot 31.

[0030] Working principle: First, the inner lining component 8 supports the hollow inner cavity of the drum 4 to prevent deformation. Then, the gear assembly drives the rotating shaft 7 to rotate the drum 4, thereby achieving the purpose of winding the cable.

[0031] During the winding process, due to environmental limitations, the free end of the cable gets stuck at a certain position, preventing the cable from being wound onto the drum 4. Under the action of the winding rotation, the cable becomes taut. At this time, the drive motor 2 will be stopped abruptly due to tension monitoring alarm to avoid the cable breaking due to continuous winding. After the emergency stop, the drive motor 2 cannot immediately reverse the rotation to release the cable from the taut state.

[0032] By increasing the internal pressure of the regulating cavity 22 using the regulating air pump 9, the piston 23 drives the push rod 40 to press the telescopic shaft 28. The spring 32 is compressed, which in turn drives the insert 35 to separate from the slot 31. At this time, the telescopic shaft 28 and the fixed shaft 29 can rotate relative to each other. At this time, the drum can be manually driven to rotate in the opposite direction to release the tension of the cable. The reverse rotation will only be transmitted from the gear ring 20 to the transmission gear 27, and will not cause the reverse meshing drive of the driving gear 25 and the linkage gear 26, thus ensuring the stability of the transmission between the gears and avoiding the phenomenon of tooth cutting between the teeth.

[0033] Example 2: Based on Example 1, in order to monitor the tension and ensure the orderly winding of the cable in the axial direction of the drum.

[0034] A cable laying assembly is provided on one side of the base 1, facing the extension direction of the drum 4. The cable laying assembly includes a screw 17 driven by a cable laying motor 13. A cable laying block 14 is provided on the screw 17, which slides along the axial direction of the drum 4. A pair of clamping arc plates 15 for clamping cables are symmetrically distributed on the upper end of the cable laying block 14. An air bladder 16 is pressed between the other side of the clamping arc plates 15 and the side wall of the cable laying block 14. A threaded hole 38 is provided through the lower end of the cable laying block 14, which is threadedly connected to the screw 17. A barometer for monitoring the internal pressure of the air bladder 16 is provided in the cable laying block 14.

[0035] By setting a pair of clamping arc plates 15, the cable winding is clamped. With the axial sliding of the cable guide block 14, the cable is wound in an orderly manner with limited positioning. When the free end of the cable is stuck, the cable will be excessively squeezed to one side as the cable guide block 14 slides laterally, causing the airbag 16 to be compressed. The internal pressure of the airbag 16 can be monitored in time using a barometer. Once excessive compression occurs, an alarm can be set in time to stop the winding.

[0036] Example 3: Based on Example 1, since the reverse rotation angle of the drum 4 is difficult to control, it will cause the insert 35 and the slot 31 to be difficult to be inserted into each other. Moreover, it is too laborious to manually reverse drive the drum. Therefore, a side frame 3 is also designed. The side frame 3 includes a side frame 5 and a cover plate 6. The side frame 5 is provided with a side hole on the side near the drum 4 to accommodate the extension shaft 28 into the inner cavity of the side frame 5. One end of the extension shaft 28 extends into the side frame 5, and a long gear 12 is provided at the end of the extension shaft 28. An adjusting shaft 11 is rotatably installed in the side frame 5. An adjusting gear 10 that meshes with the long gear 12 is fixedly sleeved on the adjusting shaft 11. A hole is provided on the cover plate 6 facing the adjusting shaft 11. A telescopic rod that can extend and retract along the hole to the outside of the cover plate 6 is provided at the end of the adjusting shaft 11.

[0037] By setting the adjustment shaft 11, long gear 12 and adjustment gear 10 to cooperate, the drive of transmission gear 27 and gear ring 20 is extended to the side frame 3. During the reverse drive, the adjustment shaft 11 can drive the long gear 12 and adjustment gear 10 to mesh, thereby driving the rotation of telescopic shaft 28, which facilitates the reverse drive of drum 4, and at the same time facilitates fine adjustment of the angle of insert 35 on telescopic shaft 28, so that insert 35 and slot 31 are re-corresponding and inserted.

[0038] The length of the insert 35 that is inserted into the slot 31 is less than the width of the teeth that mesh between the gear ring 20 and the transmission gear 27. The length of the insert 35 is less than the width of the teeth that mesh between the long gear 12 and the adjusting gear 10. The end nut of the stepped connecting rod 41 is fixed with an auxiliary frame 18 that is sleeved on the outer wall of the rotating shaft 7. The auxiliary frame 18 is provided with a through hole facing the telescopic shaft 28. The telescopic shaft 28 slides through the auxiliary frame 18 through the bearing 19 installed in the through hole.

[0039] By limiting the length of the insert 35, the telescopic drive of the telescopic shaft 28 will not cause the gear transmission to fall off. By setting the auxiliary frame 18, the free end of the telescopic shaft 28 will not be deformed due to gravity due to excessive extension, thus further ensuring the stability of the transmission connection.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
