The number of cable reels is odd, including fixed reels 19 and movable reels 21. The fixed reels 19 are odd-numbered and are all fixedly connected to the hollow shaft. The movable reels 21 are even-numbered and slide on the hollow shaft. Fixing plates 20 are fixed on the left side of the even-numbered reels. The lower part of the fixing plates 20 passes through the elongated holes 25 and is fixed to the connecting rod 24. Both ends of the hollow shaft are set in bearing seats 3 of the fixed crossbar 18 located in the middle of the fixed frame 1.

The support plate 13 is C-shaped and fixed to the pad on the upper part of the fixed crossbar 18 with its opening facing upward. The push rod 14 is L-shaped and horizontally inserted into the through holes of the two arms of the support plate 13. The spring 12 is sleeved in the middle of the push rod 14 and is located in the opening of the support plate 13. A vertical through hole is provided in front of the spring 12 on the push rod 14. The pin 11 passes through the through hole and is located on the inner surface of the arm plate of the support plate 13.

[0027] Furthermore, a support base 5 is fixed at the lower part between the vertical supports of the fixed frame 1, and adjustable height support feet and casters are installed at the four corners of the lower part of the fixed frame 1 to facilitate movement and fixation in different terrains.

[0028] When using a thin cable, the position of the cable reel 2 in the multifunctional cable winding device described in this utility model is as shown in the attached figure. Figure 3 As shown, in this embodiment of the invention, nine cable winding reels 2 are used, with eight spaces for winding cables. A drive motor 6 starts and drives a tension motor 7 to rotate. A tension sensor is fixed to the transmission shaft B on which the large gear is mounted, monitoring the tension in real time and feeding it back to the external control system. When the tension is abnormal, the control system controls the tension motor 7 to adjust its speed to maintain the tension within a set range. A clutch 8 is fixedly connected to the output end of the tension motor 7. When the knob of the clutch 8 is rotated to the "engaged" position, the output shaft of the clutch 8 is fixedly connected to the small gear 10 of the transmission assembly. The small gear drives the large gear to rotate via a chain. The drive shaft B on the wheel is fixedly connected to the rotating shaft 4, thereby driving the drive wheel 15 on the rotating shaft 4 and the nine cable take-up and drop reels 2 to rotate, realizing the take-up and drop of the cable; when the drive motor 6 is de-energized, it no longer drives the nine cable take-up and drop reels 2 to rotate, the knob of the clutch 8 is rotated to "disengage", the clutch 8 is disengaged from the pinion 10 of the transmission component, the rightmost cable take-up and drop reel 2 is manually fine-tuned, so that the push rod 14 is aligned with the through hole on the cable take-up and drop reel 2 and pressed in, the pin 11 is inserted into the insertion hole on the push rod 14, and the spring 12 is pressed against the pin 11 for limiting; multiple weight-reducing holes 16 are opened on the cable take-up and drop reel 2 along its circumference.

[0029] When replacing with a thicker cable, pull the push rod 22 to the left. The push rod 22 moves the connecting rod 24 to the left. At the same time, the fixing plate 20 fixed on the connecting rod 24 moves the moving plate 21 along the elongated hole 25 towards the leftmost fixing plate 19. The rightmost fixing plate 19 remains stationary. The previous eight spaces are merged into four spaces, making the space larger and suitable for the use of thicker cables. When replacing with a thinner cable, push the push rod 22 to the right. The push rod 22 moves the connecting rod 24 to the right. At the same time, the fixing plate 20 fixed on the connecting rod 24 moves the moving plate 21 along the elongated hole 25 towards the rightmost fixing plate 19. The drive motor 6, tension motor 7, and tension sensor described in this utility model are all connected to the external control system via signals. The handbrake assembly 26 is existing technology. It is fixed to the lower side of the transmission wheel 15 by the handbrake fixing plate 27, which is fixed to the lower part of the fixed crossbar. The handbrake assembly 26 is located between the two columns of the fixed frame 1. Its working principle is to generate braking force by using the friction force between the drum brake and the brake gear. The transmission shaft C29 connected by bearings is installed on the handbrake fixing plate 27. Both the brake gear and the drum brake are fixed on the transmission shaft C29. The brake gear meshes with the transmission wheel 15, thereby effectively braking the cable reel 2. The drum brake is used for braking and is connected to a steel wire rope. The tightness of the brake is controlled by the steel wire rope. The steel wire rope is connected to the steel wire rope adjuster to adjust the tightness of the steel wire rope, thereby controlling the tightness of the drum brake. Other specific connection relationships are not detailed. When the power is off, the drive motor 6 cannot work. In order to prevent the cable from falling too fast due to gravity and causing safety factors, the clutch 8's engagement / disengagement knob is mainly used when the motor cannot be driven. The clutch knob can be rotated to "disengage" so that the cable can be manually reeled in and out.

[0030] The parts of this utility model not described in detail are existing technologies.

[0031] The embodiments selected herein for the purpose of disclosing the inventive objectives of this utility model are currently considered appropriate; however, it should be understood that this utility model is intended to include all variations and modifications of the embodiments that fall within the scope of this concept and utility model.
