[0021] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0022] like Figure 1 As shown, the cable reel provided in this embodiment includes a first fixed flange 1, a bushing 2, a cover plate 3, a cylinder 4, a base 5, a drive source 23, a first slip ring box 18, a second slip ring box 11, a drive source 23, a limiting device 25, a support block 28, and a support frame 8.

[0023] like Figure 1 , Figure 2 The drive source 23 includes a reduction gearbox 6, a gear set 21 disposed inside the reduction gearbox 6, and a motor 22 mounted outside the reduction gearbox 6. The output shaft of the motor 22 is connected to the input end of the gear set 21, and the output end of the gear set 21 is connected to the first main shaft 20. A first slip ring box 18 and a second slip ring box 11 are arranged sequentially from the reduction gearbox 6. In addition, the drive source 23 may also include bearings, bearing seats, bearing covers, retaining rings, and reinforcing ribs, etc., which are common structures for the gears inside the reduction gearbox 6, and their specific connection methods will not be described in detail here. The first slip ring box 18 may be made of 304 stainless steel and sealed with a gasket to achieve rust prevention.

[0024] The base 5 has a gearbox 6 mounted on one end of its upper surface and a support frame 8 mounted on the other end of its outer surface. The support frame 8 has a vertically extending oblong hole 81, and the base 5 has a mounting hole 51. The oblong hole 81 is aligned with the mounting hole 51 and fixed by bolts 29. The second slip ring box 11 is placed on the support frame 8. The oblong hole 81 has an adjustable distance, allowing adjustment of the installation height of the second slip ring box 11 so that the axis of the second spindle 24 coincides with the axis of the first spindle 20. The support block 28 is located on the base 5, and the first slip ring box 18 is placed on the support block 28.

[0025] The first spindle 20 passes through the gear set 21. One end of the first spindle 20 extends out of the gearbox 6 and is fitted with a bushing 2. A cover plate 3 is fitted onto the outer end of the bushing 2. The other end of the first spindle 20 extends out of the gearbox 6 and into the first slip ring box 18, where it connects to the first support plate 26. A first fixing flange 1 is bolted to the bushing 2, and a cylinder 4 is bolted to the first fixing flange 1. The cylinder 4 is used to wind up the power cable, control signal cable, and fiber optic signal cable.

[0026] The first slip ring box 18 contains a high-voltage slip ring 19. One end of the high-voltage slip ring 19 is connected to a first support plate 26, and the other end is connected to a second support plate 27. A second main shaft 24 is connected to the second support plate 27. Before assembly, the high-voltage slip ring 19 should be tested for runout, which must not exceed 0.3 mm. The high-voltage slip ring assembly 19 must undergo withstand voltage and insulation resistance tests, requiring an AC withstand voltage of 42 kV for 1 minute, and an insulation resistance of not less than 2500 ohms between phases and between phase and ground.

[0027] The second slip ring box 11 contains a conductive slip ring 10, a control line terminal 9, an optical fiber rotary transmitter 13, a rotary junction box 14, and a limiting device 25. The optical fiber rotary transmitter 13 is installed in the second slip ring box 11 via a second fixed flange 12. The rotary junction box 14, the conductive slip ring 10, and the optical fiber rotary transmitter 13 are arranged sequentially from one side of the first slip ring box 18. The second main shaft 24 passes through the rotary junction box 14 and the conductive slip ring 10 and then connects to the optical fiber rotary transmitter 13. The second slip ring box 11, the first support plate 26, and the second support plate 27 are all made of 304 stainless steel.

[0028] The first spindle 20 and the second spindle 24 are hollow inside. The power line runs from inside the first spindle 20 and connects to the high-voltage slip ring 19. The control signal line and the fiber optic signal line run from inside the second spindle 24, pass through the rotating terminal block 14, and are respectively connected to the conductive slip ring 10 and the fiber optic rotary transmitter 13. Then, the control signal line and the fiber optic signal line are led out from the conductive slip ring 10 and the fiber optic rotary transmitter 13 and connected to the corresponding interfaces on the control line terminal 9.

[0029] The limiting device 25 includes a limit switch 15, a first sprocket 16, a chain 17, and a second sprocket 7. The second sprocket 7 is mounted on the second main shaft 24 and moves with the second main shaft 24. The limit switch 15 is located beside the second main shaft 24. The input end of the limit switch 15 is connected to the first sprocket 16. The chain 17 connects the first sprocket 16 and the second sprocket 7. The limit switch 15 is electrically connected to the drive source 23. The first main shaft 20 is driven to rotate by the drive source 23, thereby causing the high-pressure slip ring 19 and the second main shaft 24 to rotate together. The rotation of the second main shaft 24 causes the second sprocket 7 on it to move. The second sprocket 7 drives the first sprocket 16 to rotate via the chain 17, thereby driving the limit switch 15 to rotate via the first sprocket 16. The limit switch 15 is model LX-36-88, and its working principle is omitted here.

[0030] The cable winding and unwinding process of the cable reel provided by this utility model is as follows: When winding the cable, the magnetic field rotation direction of the motor 22 (torque motor) is the same as the rotation direction of the drum 4. The motor 22 performs positive work, and its output torque is transmitted to the drum 4 through the gear set 21, thereby winding the cable onto the drum 4 and completing the winding operation. When unwinding the cable, the magnetic field rotation direction of the motor 22 is opposite to the rotation direction of the drum 4. The drum 4 reverses direction under the drag force of the cable. At this time, the motor 22 performs negative work, and its output torque is transmitted to the drum 4 through the gear set 21, forming cable tension. Under the action of tension, the cable smoothly detaches from the drum 4, completing the unwinding operation.

[0031] The cable reel provided by this utility model has the following wiring method: Since the cable is of three types—power cable, control signal cable, and optical fiber—it includes a high-voltage slip ring, a conductive slip ring, and an optical fiber rotary transmitter. The power slip ring mainly transfers electrical power, the conductive slip ring mainly transmits analog control signals, and the optical fiber rotary transmitter is mainly responsible for transferring digital signals such as video and telephone signals.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
