Description

Technical Field

[0001] This invention relates to an improvement in cable winding and unwinding technology, belonging to the field of power equipment, and particularly to a cable winding and unwinding device. Background Technology

[0002] The cable winding and unwinding mechanism is a core component in power equipment technology used to control rotating machinery. Currently, lifting equipment in offshore platforms (ports) and tower cranes in civil construction industries all require cables for winding during rotation. These devices can currently achieve 360° rotation during winding, and conductive slip rings are often used for cable connection.

[0003] Currently, the maximum current of commercially available conductive slip rings is 3000A. During use, they often experience burning, resulting in unstable performance and significantly impacting normal operation. If the current is increased further, they will fail to meet the usage requirements. A certain type of electromagnetic device operates at a normal current of 1mA, which is transmitted to a rotating device requiring 360° rotation. Currently available conductive slip rings cannot meet this requirement. Existing electromagnetic devices use a cable carrier + fixed base + guiding device for guidance and constraint, resulting in only 90° rotation to the left and right. Larger angle rotations require adjusting the attitude of the electromagnetic device's bottom. The bottom has numerous support structures, and adjusting the attitude of the bottom of the electromagnetic device is time-consuming and requires manual labor.

[0004] Chinese patent application CN201921574441.7, filed on September 21, 2019, discloses a cable winding mechanism for a telescopic beam electromagnet, belonging to the field of electromagnetic crane technology. It includes a beam body and a telescopic beam. The telescopic beam is movably installed within the beam body, extending or retracting relative to the beam body. A winding device is fixedly installed above the beam body. A cable clamp is installed at the end of the telescopic beam protruding from the beam body, through which a cable passes. One end of the cable passes through the cable clamp and protrudes, while the remaining cable within the clamp is fixedly connected to it. The other end of the cable is wound around the winding device. The extension or retraction of the telescopic beam relative to the beam body causes the cable on the winding device to be passively wound and unwound in coordination with the telescopic beam's extension and retraction. This application improves the reliability of cable winding and unwound; avoids the potential hazards of cable damage or electromagnet burnout due to friction between the cable and the cable tray, ensuring the safe and reliable operation of the electromagnet; however, it still does not solve the problem of the electromagnetic device's inability to withstand large currents.

An actuating mechanism is connected to the inner ring of a third cable assembly via an actuating shaft. One end of the first cable assembly is connected to one end of the third cable assembly, and one end of the second cable assembly is connected to the other end of the third cable assembly. The cable ring includes multiple cables and multiple twisted pairs, all of which are staggered within the outer ring.

Compared to commonly used conductive slip rings, its current-bearing capacity is significantly enhanced, it is less prone to burning, and its performance is more stable. Therefore, this design can withstand large currents and operates stably.

[0023] 2. In the cable winding and unwinding device of the present invention, a rotating mechanism is provided on the outer side of a first cable assembly, and two rotating mechanisms are provided on the outer side of a second cable assembly. An actuator is connected to the inner ring of a third cable assembly via an actuator shaft.

The first cable assembly includes a cable coil, one end of which is connected to one end of a sealing flange, and the other end of which passes through a rotating cable mounting base and is movably connected to the rotating cable mounting base. The other end of the cable coil is connected to one end of two sealing flanges, and the other end of the two sealing flanges is connected to one end of a watertight socket. The actuator... The device rotates clockwise in the direction of the instruction. The second cable assembly is stretched by the two rotating mechanisms, reducing the number of cable coils on it. The second rotating mechanism then extends, increasing the number of cable coils on the first cable assembly. The first rotating mechanism compresses the coils, keeping both the first and second cable assemblies taut. Friction occurs during the stretching process, allowing the cable coils to lengthen or shorten between the first and second rotating mechanisms. The rotating mechanism can adjust 180° clockwise, and similarly, the actuator can rotate 180° counterclockwise, enabling 360° adjustment of the high-current electromagnetic device. Therefore, this design allows for 360° adjustment and is easy to operate.

This locks the cable coil into the variable-diameter drum formed by the first, second, third, and fourth support blocks. The cable coil's entry and exit follow a predetermined track, thus preventing the cable coil from getting tangled in the variable-diameter drum. Therefore, this design is safe to use and has a good fastening effect. Attached Figure Description

[0046] The positioning screw 64 passes through the threaded hole 66 and is connected to the top of the extrusion plate 65. The bottom of the extrusion plate 65 abuts against the outer side of the cable ring 12. The extrusion plate 65 is an elastic plate. The bottom of the extrusion plate 65 is an arc-shaped surface 651. The curvature of the arc-shaped surface 651 is the same as the curvature of the outer ring of the cable ring 12.

[0047] The cable through hole 63 is provided with an O-ring 13. On the front side of the rotating frame 61, outside the cable through hole 63, two O-rings 14 are provided. One end of the cable ring 12 passes through the two O-rings 14, the first O-ring 13, and the cable through hole 63 in sequence and extends to the outside of the rotating frame 61.

[0050] The first support block 181, the second support block 182, the third support block 183, and the fourth support block 184 have the same shape and size. The arc surface 185 of the first support block 181 has the same arc as the inner diameter of the cable coil 12. Multiple cable grooves 186 are provided on the outer side of the fourth support block 184. The cable coil 12 is placed in the cable groove 186. The length of the fourth support block 184 increases along the Z-axis.

[0051] The principle of this invention is explained as follows: Upon receiving a system command, the actuator 19 rotates clockwise in the command direction. The actuator 19 contains a power source that drives its rotation. The two cable assemblies B are elongated by the two rotating mechanisms 180, reducing the number of cable coils 12 on them, and causing the rotating mechanisms 180 to extend. The cable assembly A is drawn into the variable-diameter drum by the rotating mechanism 18, and the cable coils 12 wind around a specific cable groove 186, increasing the number of cable coils 12 on the cable assembly A. A spring 171, a second spring 172, and a third spring 173... 73. The four springs 174 will be compressed; due to the action of the springs, the cable coils 12 of both cable assembly A and cable assembly B are in a taut state. During the stretching process, the cable coils 12 will generate a certain amount of friction. Each time the cable coils 12 are lengthened or shortened in the rotary mechanism, the rotary mechanism can be adjusted to a forward angle of 180°. The cable coils 12 will enter the specific cable groove 186, ensuring that the cable coils 12 of the first rotary mechanism 18, the second rotary mechanism 180 and the actuator 19 will not be entangled. Similarly, the actuator 19 can rotate 180° counterclockwise.

[0052] Example 1:

[0053] A cable winding and unwinding device includes a cable assembly A, a cable assembly B, a cable assembly C, a rotating mechanism 18, a rotating mechanism 180, and an actuator 19. A rotating mechanism 18 is disposed on the outer side of the cable assembly A, and two rotating mechanisms 180 are disposed on the outer side of the cable assembly B. The actuator 19 is connected to the inner ring of the cable assembly C via an actuating shaft 15. One end of the cable assembly A is connected to one end of the cable assembly C, and one end of the cable assembly B is connected to the other end of the cable assembly C. The structure of component C is the same, and the structure of the first rotating mechanism 18 and the second rotating mechanism 180 is the same; the cable assembly A includes a cable coil 12, one end of which is connected to one end of a sealing flange 3, and the other end of which passes through the rotating cable mounting seat 6 and is movably connected to the rotating cable mounting seat 6. The other end of the cable coil 12 is connected to one end of the second sealing flange 9, and the other end of the second sealing flange 9 is connected to one end of the watertight socket 11. The cable coil 12 includes multiple cables 121 and multiple twisted pairs 122, and all the cables 121 and twisted pairs 122 are interleaved and arranged in the outer ring 123.

[0054] In application: Upon receiving a system command, the actuator 19 rotates clockwise in the command direction; the second cable assembly B is stretched along with the second rotary mechanism 180, resulting in fewer cable coils 12 on the second cable assembly B. The second rotary mechanism 180 will extend, increasing the number of cable coils 12 on the first cable assembly A. Since the first rotary mechanism 18 will compress, the cable coils 12 in both the first cable assembly A and the second cable assembly B are in a taut state. During the stretching process, the cable coils 12 will generate a certain amount of friction. Each time, the cable coils 12 can be stretched or shortened between the first rotary mechanism 18 and the second rotary mechanism 180. At this time, the rotary mechanism can be adjusted by a forward 180° angle. Similarly, the actuator 19 can rotate counterclockwise by a 180° angle.

Compared to commonly used conductive slip rings, its current-bearing capacity is significantly enhanced, it is less prone to burning, and its performance is more stable. The length of the four support blocks 184 increases along the Z-axis. During the stretching process, the cable coil 12 enters the specific cable trough 186 through fixed clamps. The cable coil 12 is stretched in layers, with each cable having its own inherent track and a defined path. This locks the cable coil 12 into the variable-diameter drum formed by the first, second, third, and fourth support blocks 181, 182, 183, and 184. The cable coil 12's entry and exit follow a predetermined track, preventing it from becoming entangled within the variable-diameter drum.
