Description

Technical Field

[0001] A ship shore power cable retracting winch, used for the retracting of shore power cables when the ship is docked at the port.

[0002] The invention relates to the technical field of design and manufacturing of shore power cable retracting and releasing equipment. Background Art

[0003] When existing ships are anchored in seaports or inland ships are anchored in ports on rivers, for the sake of environmental protection and energy saving, ships anchored in ports are required to shut down the shipboard generator that supplies power to the hull and instead supply power to the ship through the power supply located on the shore side of the port. Therefore, cables are needed for circuit connection, and at this time, the cables are often needed to be reeled in by a cable winch, which mainly involves pulling the connecting cable on the ship to the shore and connecting it to the shore power connection device to obtain electricity. The connecting cable is generally stored in the drum of a winch or an electric hoist, which basically includes an equipment base and a drum on the base, on which there is a threaded rope groove for winding a wire rope, one end of the wire rope is fixed to one side of the drum, and the wire rope is wound on the threaded rope groove of the drum, and the wire rope on the drum is wound around the threaded rope groove on the drum or moved horizontally left or right through the guide wheel device in the guide rod type threaded guide mechanism, so that the cable will not be tangled, and is arranged on the same drum as above Although traditional shore power winches can realize the retraction and release of cables, most of them are still manually controlled and cannot automatically retract and release cables according to the rise and fall of water levels or the movement of pontoons. In order to prevent improper tension on cables caused by ship movement due to water level fluctuations or other reasons, special personnel are required to be on duty; in seasons with frequent water level changes, the need to retract and release cables is very frequent, which is time-consuming and labor-intensive. Slow manual operation or improper operation may also easily lead to the risk of cable breaking and deformation; in addition, traditional technology also has electric winches, including brackets, partitions, heat dissipation fan blades, connecting rings, motors and fixing seats. The advantage of this cable winch is that it can continuously dissipate heat to the drive box when the drive box is heated, thereby ensuring that the drive device inside the drive box can work normally; however, in order to dissipate heat, the electric winch of the prior art has a relatively complex mechanism, and it is not easy to clean up adhering debris, which is not conducive to the storage of cables.

[0004] The technology with patent announcement number CN218841371U discloses "a shore power cable winch for ships with a guiding function". The utility model discloses a shore power cable winch for ships with a guiding function, which relates to the technical field of cable winches and includes a base plate, a support seat is fixedly installed at the bottom end of the base plate, and the surface of the base plate is connected to a vertical plate, a rotating rod is arranged above the vertical plate, and the outer wall of the rotating rod is connected to a cable drum, and a servo motor is connected to one side of the rotating rod. The utility model arranges a cross plate on the front end face of the cable drum, and under the action of a sliding column and a slideway, the adjusting rod can drive the fixed base to move flexibly, and by arranging a telescopic spring on the outer wall of the adjusting rod, the adjusting rod can be adjusted in position with the force applied by the shore power cable when it moves. Compared with the existing external force driving the reciprocating movement of the cable guide seat, the cable is more flexible when guiding the cable, avoiding interference with the moving quality and moving efficiency of the cable, and the structure is simple, saving driving resources, and energy saving and environmental protection. This technology requires adjusting the adjustment rod set on the slide to drive the fixed base to move in position to adjust the length of the cable. It is inconvenient to operate when the tide changes at night, and the position cannot be adjusted in real time. There is still a risk of breaking the cable.

[0005] Another utility model patent with patent announcement number CN211283284U discloses "a shore power cable winch for ships with a cable guiding function". This utility model is a shore power cable winch for ships with a cable guiding function, including a support platform, a fixing frame and a function box, the fixing frame is fixedly connected to the upper surface of the support platform, the function box is fixedly connected to the side of the support platform, the inside of the function box is fixedly connected to a fixed platform, the upper surface of the fixed platform is fixedly connected to a first motor, the other end of the output shaft of the first motor is fixedly connected to a first rotating shaft, and a first bearing is penetrated through the surface of the support platform; this utility model, by arranging a sliding rod and a sliding sleeve, prevents the threaded nut carrying the cable guide rod from being offset during the movement process.

[0006] The above two patents can realize the electrically driven cable retraction and release, but these electric cable retraction and release winches are driven by electric motors. In order to reduce speed, a set of deceleration mechanism must be set up so that the winch can have a suitable rotation speed when retracting and releasing the cable. In addition, only electrically driven cable winches cannot automatically realize cable retraction and release when the water level changes. Therefore, manual supervision is still required to ensure that no damage is caused to the cable when the water level changes, or only short-term docking can be achieved, which is not suitable for ships that need to stay overnight or dock for a long time.

[0039] Example 1: Connection of left-right rotating ball screw and cable guide

[0040] A continuous integral structure with a rotating diamond block 104 in the middle and rotating diamond block tail ends 103 at both ends is formed to surround the left-handed and right-handed rolling ball screws 10. Two groups of left-handed and right-handed rolling ball screws 10 arranged alternately form a rotating rolling ball tie rod. The two tail ends of the rotating diamond block tail ends 103 of the first group intersect with the protruding part of the diamond block protruding in the middle of the second group of rotating diamond blocks 104, forming the left-handed and right-handed rolling ball screws 10. The formed left-handed and right-handed rolling ball is square.

[0041] The same alternating concave-convex structure is arranged at both ends of the left-right rotating ball screw 10, specifically: the protruding block corresponds to the tail end 103 of the rotating diamond block at both ends on the ball screw, and the concave block corresponds to the protruding block of the rotating diamond block 104, so as to form a reversal of the cable arrangement moving slide 29 at the front end of the cable arrangement 12;

[0042] The cable arranger 12 has a square hole in the middle, and the square hole is slidably sleeved on the corresponding square cable arranger sliding rod 11. The fixed parts at both ends of the cable arranger sliding rod 11 are circular bolt structures, which are fixed to the rack side plates 17 on both sides by bolts; a slide connector 28 is provided at the front end of the cable arranger 12, and the slide connector 28 is rotatably arranged on the side of the cable arranger 12 opposite to the left and right rotating roller screw 10, and a cable arranger moving slide 29 is provided at the front end of the slide connector 28. Since the slide connector 28 is rotatably arranged at the front end of the cable arranger 12, the cable arranger moving slide 29 can be moved. The slide structure for realizing left-right deflection is driven by the screw motor 102. When the slide of the cable displacer moving slide 29 moves to the two ends of the screw, it will encounter the concave-convex structure that appears alternately at the two ends of the left-right rotating roller screw 10. Since the cable displacer moving slide 29 is set on the rotatable slide connector 28, and the slide connector 28 can rotate at the front end of the cable displacer 12, when the protruding block meets the cable displacer moving slide 29, it is forced by the protruding block and driven by the mechanical structure to automatically reverse direction and be forced to reverse direction into the slideway in the other direction, thereby realizing the reversing movement.

[0043] Preferably: when the shore power is connected and there is no electricity temporarily, since the cable has a certain weight, the left-right rotating ball screw 10 is also driven to rotate when the cable is pulled, and the cable arranger 12 arranged in front of the left-right rotating ball screw 10 is also driven to move left and right in the slideway of the left-right rotating ball screw 10 because the cable arranger moves the sliding piece 29, so as to realize the arrangement of cables in the absence of electricity;

[0044] Example 2: Installation and use of tension sensor and planetary gear

[0045] There are two tension sensors 8, one on the top and one on the bottom, and the cable passes between the two tension sensors 8; when there is high tide or low tide, the cable is affected by the change in distance, and the tension will be different. When the set tension value is reached, the tension data detection box 9 will collect the tension data of all cables 14 and transmit it to the controller 1. The controller 1 will start the solenoid valve 23 in real time according to the change of data, loosen the brake belt 20 set in the inner frame 24, and release the cable 14, which can ensure that the cable will not be broken; when the cable is too long, the tension sensor 8 will also transmit the data to the controller 1 through the tension data detection box 9, and supply power to the motor 2, and transmit the power to the planetary gear 6 through the driving gear 3 and the transmission gear 4, so as to drive the cable reel 7 to rotate and retract the cable;

[0046] The planetary gear 6 is fixed to one end of the cable reel 7, so when the planetary gear 6 rotates, it drives the cable reel 7 to rotate and retract the loose cable to prevent it from being cut or damaged by friction.

[0047] A bearing is sleeved in the center of the planetary gear 39, and a sleeve 46 is sleeved in the inner hole of the bearing. The length of the sleeve 46 is greater than the gear width of the planetary gear 39;

[0048] Cover plates 45 are provided on both sides of the planetary gear 6, and right-angle flanges 47 turned inward are provided on the edges of the cover plates 45;

[0049] The planetary gear ring 50 of the planetary gear 6 is a structure with inner teeth 38 and outer teeth 48. A groove 49 is provided between the inner teeth 38 and the outer teeth 48. The width and depth of the groove 49 are matched with the right-angle flange 47 provided on the edge of the cover plate 45. After installation, the planetary gear ring 50 of the planetary gear 6 is driven to rotate by the transmission gear 4, and the inner teeth 38 of the planetary gear ring 50 drive the planetary wheel 39 to rotate, and the planetary wheel 39 drives the sun gear 40 to rotate, and then drives the cable reel 7 to rotate, so as to realize the work of retracting and releasing the cable;

[0050] Example 3: Manual Brake

[0051] In order to meet the needs of emergency, a manual brake handle 26 for emergency braking is designed. When there is no power supply and it is urgent to retract or release the cable 14, a manual brake mechanism is also arranged in the frame of the machine. The manual brake mechanism is fixed in the frame and includes a brake cylinder 22 and a manual brake handle 26. Under normal circumstances, before retracting or releasing the cable 14, the controller 1 is started to supply power to the solenoid valve 23 to release the brake. After the work of retracting or releasing the cable 14 is completed, since the solenoid valve is a double-side battery valve, the controller 1 supplies power to the other end of the solenoid valve 23 to tighten the brake belt 20. After the brake disc 21 is braked, the cable reel 7 is also braked; in the absence of electricity, the brake belt 20 can be pulled by the brake handle 26 to implement braking;

[0052] Embodiment 4: Control of electrical appliances:

[0053] Connection of wires: The rear end of the controller 1 is connected with the motor 2, the tension sensor 8, the screw motor 102, the tension data detection box 9 and the brake battery valve wire 23; when the machine needs to be used, first unplug the cable plugged into the cable input socket 18 of the machine, then turn on the switch set on the controller 1, release the cable, start the machine and connect it to the shore power box;

[0054] After the shore power is plugged in, the cable on board is connected to the cable input socket 18. According to this sequence, it is possible to prevent the cable on board from being entangled with the cable on board when the cable reel 7 rotates, causing confusion of the cable on board;

[0055] When the water level changes during high tide or low tide, the tension sensor 8 detects the tension of the cable, transmits the data to the control box 1 through the data detection box 9, and starts the motor 2 to tighten or release the cable in real time to prevent the cable 14 from being broken or squeezed;

[0056] Example 5: Equipment Installation

[0057] Installation of the rack: The rack 17 is fixedly installed on the base 37, and a rack fixing bolt hole 25 is provided on the bottom surface of the rack side plate 17.

First, assemble the left baffle plate 30 and the right baffle plate 32 of the drum with the cable drum 7, preferably by welding. The cable drum 7 is a hollow cylinder with a central axis passing through the middle. The central axis is also a hollow tube structure. Then, drill a cable insertion hole 31 from the cable drum 7 close to the left baffle plate 30 of the drum. The inclined hole is inclined to the left until the central axis of the center is drilled through. Insert a curved cable guide 41 into the drilled cable insertion hole 31, and then The tail end of the cable conduit 41 is welded to the cable insertion hole 31, and the welding surface is polished flat so as not to wear the cable; then the planetary gear 6 is inserted into the central shaft outside the baffle 32 of the cable drum 7, and a keyway is provided on the central shaft, and a fixed key is provided in the keyway, and the fixed key is matched with the keyway provided in the inner hole of the sun gear 40 at the center of the planetary gear 6, and the inner hole diameter of the sun gear 40 at the center of the planetary gear 6 matches the outer diameter of the central shaft. After installation, under the fixation of the keyway, the sun gear 40 can rotate with the cable drum 7 to implement the retraction or release of the cable;

[0059] See also Figure 5: Three fixing bolt holes are provided on the right frame 171 for inserting fixing bolts 33 that pass through the three planetary wheels 39 in the planetary gear 6. After the planetary gear 6 is installed, the fixing bolts 33 fix the three planetary wheels 39 and fix the planetary gear 6 to the right frame 171 at the same time; the inner and outer surfaces of the planetary gear ring 50 are provided with gear teeth, and planetary gear cover plates 45 are provided on both sides of the planetary gear 6.

[0060] Left and right bearings 42 and 421 are respectively arranged at both ends of the central axis of the cable drum 7. The bearings are ball bearings with balls 43. The left and right bearings 42 and 421 are respectively sleeved on the left and right frames 17 and 171 on both sides. In order to prevent the central axis from being separated from the frames when rotating, bearing glands 34 and 341 are arranged on the left and right frames 17 and 171 on both sides. The diameter of the center hole of the bearing glands 34 and 341 on both sides is smaller than the outer diameter of the bearing.

[0062] Furthermore, the installation of the motor, the installation of the device on the base, and the connection of the power supply wires are all well known to those skilled in the art, and will not be described in detail here.

[0063] Further: when the cable is inserted through the cable insertion hole 31 and the cable conduit 41 provided on the cable reel 7, since the cable has a certain strength and the diameter of the cable insertion hole 31 and the cable conduit 41 is larger than the diameter of the cable, under the guidance of the cable conduit 41, the installation technician will easily insert the cable into the central axis and to one end of the cable input socket 18 on one side of the frame 17, and the technician will connect the wire of the cable to the cable input socket 18, and then fix the cable input socket 18 on the axis;

[0064] Preferably: the cable input socket 18 can be formed by setting a pen holder-shaped structure with an internal thread and a cable entry hole on the bottom, fixing the cable input socket 18 to the bottom of the pen holder with screws, and then screwing the internal thread into the thread at the tail end of the central shaft.
