At this time, the cable reel 150 is rotated to perform the cable winding or unwinding operation. After the winding or unwinding operation is completed, the cable reel 150 is released by the fixing assembly, so that the cable reel 150 can be preferably removed from the carrier 110.

[0030] The bottom side wall of the fixing frame 100 is provided with mounting grooves 410 on both sides along its length direction. The bottom ends of the mounting grooves 410 are provided with mounting holes 411 opposite to each other.

[0031] When the cable drum 150 is taken off the ground, the cable drum 150 can be fixed on the carrier 110 by the fixing assembly, thereby realizing the fixing of the cable drum 150 on the carrier 110.

[0032] Among them, by setting the driving component, it is possible to drive the carrier 110 to rotate on the fixing frame 100, and the carrier 110 can be kept in the current position without having to be manually maintained, which is more convenient;

[0033] Among them, by setting up the counting component, the number of rotations of the cable reel 150 can be recorded, and the length of the cable reel 150 that is used to retract and release the cable can be obtained according to the circumference of the cable reel 150.

[0034] like Figure 1-3 As shown, in this embodiment, the driving member includes a protruding block 300 provided on a side wall of the supporting frame 110 and located at the upper end, the protruding block 300 is hingedly connected to the driving rod 140, the fixing frame 100 is provided with a fixing bracket 120, and a rotatable connecting shaft 121 is provided between the fixing brackets 120, and the connecting shaft 121 is threadedly connected to a first threaded rod 130, the bottom end of the first threaded rod 130 passes through the connecting shaft 121 and is rotatably connected to the top end of the driving rod 140, and the rotating first threaded rod 130 is used to drive the supporting frame 110 to rotate.

[0035] In this embodiment, the bottom end of the first threaded rod 130 is rotatably connected to the top end of the driving rod 140 via a bearing. Since the first threaded rod 130 is threaded through the connecting shaft 121, and the connecting shaft 121 is rotatably mounted between the fixing brackets 120, when the first threaded rod 130 rotates forward and backward, it drives the driving rod 140 to pull the carrier 110 to rotate around the fixing rod 400, driving the cable reel 150 on the carrier 110 away from or contacting the ground.

[0036] The supporting frame 110 is U-shaped, and the cable reel 150 is fixed at both ends of the supporting frame 110 away from the fixing rod 400 through a fixing assembly. In order to increase the strength of the supporting frame 110, reinforcing ribs 111 are provided at the ends of the supporting frame 110 that are close to each other.

The cable reel 150 is moved by the fixing assembly so that it is pressed tightly between the clamping plate 340 and the fixing assembly. When the carrier 110 rotates, the cable reel 150 on it can be driven to rotate accordingly, and can be separated from or contacted with the ground.

[0039] In actual use of this embodiment, the fixed shaft 310 is rotatably mounted on a side wall of the carrier 110 via a rotating shaft, and the chuck 340 is fixedly mounted on the inner end of the fixed shaft 310;

[0040] The positioning pin 342 is provided to fix the cable reel 150 and the clamping disc 340 so that they can rotate synchronously.

[0045] The turntable is rotatably mounted on the end of the second threaded rod 160 through a bearing;

[0046] In actual use of this embodiment, in order to facilitate the operator to rotate the second threaded rod 160, a hand wheel 161 is provided on the side of the second threaded rod 160 away from the cable drum 150. Turning the hand wheel 161 can drive the second threaded rod 160 to rotate;

[0047] The top end of the first threaded rod 130 is also provided with a driving disc 131 for easy gripping and rotation.

[0048] Working principle: When the cable on the cable reel 150 needs to be reeled or unreeled, first roll the cable reel 150 to the carrier frame 110, align the center hole 501 with the first protrusion 341, rotate the second threaded rod 160, and move the turntable toward the cable reel 150 until the second protrusion 162 on the turntable extends into the center hole 501, and move the cable reel 150 until the first protrusion 341 is inserted into the center hole 501. At this time, align the positioning hole 502 with the positioning pin 342, so that the cable The cable reel 150 is pressed tightly between the clamping disc 340 and the rotating shaft, and then the first threaded rod 130 is rotated to make the carrier 110 rotate around the fixed rod 400, driving the cable reel 150 on the carrier 110 away from the ground. At this time, the cable reel 150 is moved to rotate the cable on it to be retracted and unreeled. After the reeling and unreeling operation is completed, the first threaded rod 130 is rotated in the opposite direction to make the cable reel 150 contact the ground, and the second threaded rod 160 is rotated in the opposite direction to release the fixation of the cable reel 150 and remove the cable reel 150.
