[0028] Please refer to Figures 1-5A lifting cable feeder includes a base 1 with an inclined surface 2 on one side. A lifting seat 3 is movably mounted on the base 1. The base 1 has a placement groove 4 that mates with the lifting seat 3. A drive chamber 5 is located inside the base 1. A bidirectional lead screw 6 is rotatably mounted inside the drive chamber 5. One end of the bidirectional lead screw 6 passes through the base 1 and is fixedly connected to a motor 7. The motor 7 is fixedly mounted on the base 1. Two movable seats 8 are threaded onto the bidirectional lead screw 6. Each movable seat 8 is slidably connected to the drive chamber 5 via a track structure. The lower end of the lifting seat 3 extends into the drive chamber 5 and engages with the two movable seats. Two support rods 9 are hinged between the moving seats 8. The lifting seat 3 is provided with an arc groove 10. Two movable plates 11 are movably provided on the base 1. Each movable plate 11 is provided with a bearing 12. A rotating rod 13 is movably provided in the bearing 12. A cable reel 14 is fixed between the two rotating rods 13. Two limit blocks 22 are fixedly provided at the lower end of the movable plate 11. Four limit grooves 23 that cooperate with the limit blocks 22 are provided on the base 1. Two electric push rods 24 are fixedly provided on the base 1. The driving end of the electric push rod 24 is fixedly connected to the movable plate 11.

[0029] In this embodiment, when the cable reel 14 needs to be installed onto the entire cable feeding frame, push the cable reel 14 so that it moves along the inclined surface 2 to the base 1, and then moves into the arc groove 10 on the lifting seat 3. Start the motor 7, and the motor 7 drives the bidirectional lead screw 6 to rotate. Since the bidirectional lead screw 6 has two threaded areas with opposite directions, the two moving seats 8 move in adjacent directions. The moving seats 8 drive the support rod 9 to rotate, and the support rod 9 pushes the lifting seat 3 upward while rotating. The lifting seat 3 drives the cable reel 14 to move, so that the rotating rods 13 on both sides of the cable reel 14 are aligned with the bearings 12. Start the electric push rod 24, and the electric push rod 24 drives the moving plate 11 to move. The moving plate 11 drives the limiting block 22 to move along the limiting groove 23 to limit it. At the same time, the moving plate 11 drives the bearing 12 to move, so that the rotating rod 13 is inserted into the bearing 12, and the cable reel 14 can be installed. After installation, the lifting seat 3 can be moved back to its original position. When cable needs to be laid out, the cable reel 14 is wrapped with cable (not shown in the attached figure). Pulling one end of the cable causes the cable reel 14 to rotate under the action of the tension. The cable reel 14 drives the rotating rod 13 to rotate through the bearing 12, thereby laying out the cable.

[0030] Please see Figures 1-5As an embodiment of stopping the rotation of the cable reel: one side of the moving plate 11 is movably provided with a brake block 15 matched with the rotating rod 13, two limiting rods 16 are slidably arranged on the brake block 15, limiting plates 17 are fixedly arranged at both ends of each limiting rod 16, the limiting plates 17 are fixedly connected with the moving plate 11, springs 18 are movably arranged outside the limiting rods 16, lifting frames 19 are fixedly arranged at both ends of the brake block 15, one side of the lifting frame 19 is slidably connected with the moving plate 11 through a track structure, and a pedal 20 is fixedly arranged at the lower end of the lifting frame 19 penetrating through the base 1, and two movable grooves 21 matched with the lifting frame 19 are arranged on the base 1.

[0031] More specifically, when it is needed to stop the rotation of the cable reel 14 during the unwinding process, the pedal 20 is pressed down with the foot, the pedal 20 drives the lifting frame 19 to move downward, the lifting frame 19 drives the brake block 15 to move downward along the limiting rod 16, the spring 18 is compressed, the brake block 15 is in contact with the rotating rod 13 and limits the rotating rod 13 through friction, so that the rotating rod 13 stops rotating, that is, the cable reel 14 stops rotating, when the foot is separated from the pedal 20, the brake block 15 moves back to the original position and separates from the rotating rod 13 under the pushing of the spring 18, and the brake block 15 drives the lifting frame 19 and the pedal 20 to move back to the original position.

[0032] In summary, when the cable reel 14 needs to be installed on the whole unwinding frame, the cable reel 14 is pushed to move along the inclined surface 2 to the base 1, and then to the arc-shaped groove 10 on the lifting seat 3, the motor 7 is started, the motor 7 drives the bidirectional screw rod 6 to rotate, because the bidirectional screw rod 6 is provided with two threads with opposite directions, the two moving seats 8 move in the adjacent directions, the moving seat 8 drives the supporting rod 9 to rotate, the supporting rod 9 rotates and pushes the lifting seat 3 upward at the same time, the lifting seat 3 drives the cable reel 14 to move, so that the rotating rods 13 on both sides of the cable reel 14 are aligned with the bearings 12, the electric push rod 24 is started, the electric push rod 24 drives the moving plate 11 to move, the moving plate 11 drives the limiting block 22 to move along the limiting groove 23 to limit it, and at the same time, the moving plate 11 drives the bearing 12 to move, so that the rotating rod 13 is inserted into the bearing 12, that is, the cable reel 14 is installed, after the installation is completed, the lifting seat 3 can move back to the original position. When unwinding is needed, the cable is wound on the cable reel 14 (not shown in the drawing), one end of the cable is pulled, so that the cable reel 14 rotates under the action of the pulling force, the cable reel 14 drives the rotating rod 13 to rotate through the bearing 12, thereby unwinding the cable.

[0033] When it is needed to stop the rotation of the cable reel 14 in the process of paying out the cable, the pedal 20 is stepped down with the foot, the pedal 20 drives the lifting frame 19 to move downwards, the lifting frame 19 drives the brake block 15 to move downwards along the limiting rod 16, the spring 18 is compressed, the brake block 15 is in contact with the rotating rod 13 and limits the rotating rod 13 through the friction force, the rotating rod 13 stops rotating, the cable reel 14 stops rotating, when the foot is separated from the pedal 20, the brake block 15 is moved back to the original position and separated from the rotating rod 13 under the pushing of the spring 18, the brake block 15 drives the lifting frame 19 and the pedal 20 to move back to the original position.

[0034] The base 1 is provided with a controller on one side, and the whole device is controlled by the controller. Since the controller is matched with common devices, it belongs to the existing mature technology, and the electrical connection relationship and specific circuit structure are not described here.

[0035] In all the above-mentioned schemes, the connection between the two components can be selected according to the actual situation, such as welding, bolt and nut cooperation connection, bolt or screw connection or other known connection mode, which is not described one by one here. In the above, whenever it is mentioned that it is fixedly connected, it is preferred to consider welding.
