Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of marine cable winch, in particular to a marine armored cable winch auxiliary equipment. BACKGROUND

[0002] It is usually necessary to equip a cable winch for cable extension on a ship, since the ship can only be parked on the water surface of the port and is far away from the land, a long cable needs to be used for connection with the land equipment in power supply, data transmission and other aspects, and therefore a cable winch needs to be provided for realizing the winding and extension of the cable.

[0003] The existing marine tow cable winch with publication number CN107381392A includes a base, limit plates are symmetrically arranged on the upper end of the base, a rotating shaft is rotatably arranged in the middle of the limit plate, a winch drum is arranged on the middle of the rotating shaft, the output end of a speed reducer is connected to the left end of the rotating shaft, the cooperation of the rotating shaft, the winch drum, the speed reducer, the winch motor and the brake device can realize the winding and unwinding of the cable, the cooperation of the sliding block, the supporting rod and the fairlead can control the winding order of the cable on the winch drum, the cooperation of the pressure sensor, the supporting rod, the through hole, the threaded hole, the threaded rod and the small motor can make the sliding block and the fairlead move back and forth between the supporting plates, the back and forth movement of the fairlead in front of the winch drum makes the cable uniformly and neatly wound on the winch drum, which ensures the accommodation capacity of the winch drum for the cable and avoids the uneven abrasion of the cable caused by the uneven extrusion friction force, thereby increasing the service life of the cable.

[0039] The pressure in the adjusting inner cavity 22 is controlled by the adjusting air pump 9, so as to adjust the position of the piston 23, when the pressure increases, the piston 23 drives the top rod 40 to press the telescopic shaft 28, so that the spring 32 is pressed, and then the insertion strip 35 is separated from the insertion slot 31.

[0040] Working principle: first use lining component 8 to realize the hollow inner cavity of the reel 4 support, prevent deformation, using the transmission of gear assembly, realize the rotation of the shaft 7 drive reel 4 rotation, achieve the purpose of winding cable.

[0041] In the winding process, due to the restriction of the environment, the free end of the cable is stuck in a position, so that the cable cannot be wound to the reel 4, under the action of winding rotation, the cable appears tight state, at this time the drive motor 2 will be stopped due to tension monitoring alarm, to avoid continuous winding causes the cable to be tight, when the emergency stop, the drive motor 2 can't immediately reverse rotation, to relieve the tight state of the cable.

[0042] The use of adjusting air pump 9 increases the internal pressure of the adjusting inner cavity 22, so that the piston 23 drives the ejector rod 40 to extrude the telescopic shaft 28, the spring 32 is extruded, and then the plug 35 is driven to separate from the plug groove 31, at this time the telescopic shaft 28 and the fixed shaft 29 can rotate relative to each other, at this time the reel can be driven by manpower to reverse rotation, to relieve the tight state of the cable, reverse rotation will only be transmitted to the transmission gear 27 by the gear ring 20, and will not cause the reverse engagement drive of the driving gear 25 and the linkage gear 26, so as to ensure the stability of the transmission between the gears, avoid the cutting phenomenon between the teeth.

[0043] Example 2: based on example 1, in order to realize the monitoring of tension, while ensuring the orderly winding of the cable on the reel axis.

[0045] By arranging a pair of clamping arc plates 15, the clamping of the winding cable is realized, and the axial sliding of the wire arranging block 14 makes the cable limited and orderly wound, when the free end of the cable is stuck, the lateral sliding of the wire arranging block 14 will cause the cable to be excessively pressed to one side, so that the air bag 16 is compressed, and the internal pressure of the air bag 16 can be monitored in time by using the pressure gauge, once the excessive compression, can alarm in time, to stop winding in time.

[0046] In the embodiment 3, the reverse rotation angle of the winding drum 4 is difficult to control, which causes the subsequent difficulty in the insertion of the strip 35 into the slot 31, and the manual reverse driving of the winding drum is too laborious. Therefore, the side frame 3 is designed. The side frame 3 comprises a side frame 5 and a cover plate 6. The side hole, in which the telescopic shaft 28 extends into the inner cavity of the side frame 5, is arranged on the side of the side frame 5 close to the winding drum 4.

The end of the adjusting shaft 11 is provided with the telescopic rod which can extend to the outside of the cover plate 6 along the aperture.

[0047] The cooperation of the adjusting shaft 11, the long gear 12 and the adjusting gear 10 extends the driving of the transmission gear 27 and the tooth ring 20 to the side frame 3. In the reverse driving process, the rotation of the telescopic shaft 28 can be driven by the driving of the adjusting shaft 11, the engagement of the long gear 12 and the adjusting gear 10, so as to facilitate the reverse driving of the winding drum 4 and the fine adjustment of the angle of the strip 35 on the telescopic shaft 28, so that the strip 35 is re-inserted into the slot 31.

[0048] The length of the strip 35 is less than the width of the teeth engaged between the tooth ring 20 and the transmission gear 27, and the length of the strip 35 is less than the width of the teeth engaged between the long gear 12 and the adjusting gear 10. The end nut of the stepped connecting rod 41 is fixedly sleeved on the auxiliary frame 18 arranged on the outer wall of the rotating shaft 7. The through hole opposite to the telescopic shaft 28 is arranged on the auxiliary frame 18. The telescopic shaft 28 is slidably penetrated through the auxiliary frame 18 through the bearing 19 arranged in the through hole.

[0049] By limiting the length of the strip 35, it is ensured that the telescopic driving of the telescopic shaft 28 will not cause the disengagement of the gear transmission. By arranging the auxiliary frame 18, the deformation of the free end of the telescopic shaft 28 due to the gravity is avoided, and the stability of the transmission connection is further ensured.
