It will be appreciated that the two rollers of each roller set 228 roll in opposite directions, as in the example of fig. 5, with the roller on the outside of the arcuate portion 227 rotating clockwise and the roller on the inside of the arcuate portion 227 rotating counterclockwise during the wire takeup process, thereby drawing the exposed cable into the housing structure 6; correspondingly, in the paying-off process, the roller positioned on the outer side of the arc-shaped part 227 rotates anticlockwise, and the roller positioned on the inner side of the arc-shaped part 227 rotates clockwise in the anticlockwise direction, so that the cable stored in the shell structure 6 is paid-off.

The wire take-up and pay-off process of the device is described in detail with reference to the wire take-up and pay-off device shown in fig. 1:
in a state before the wire rewinding, as shown in fig. 8, the cable located outside the housing structure 6 is a cable of an exposed portion, and it should be noted that the exposed portion is only used for indicating that the cable needs to be retracted into the housing structure 6 in the wire rewinding process, and parameters such as the length and the shape of the cable exposed outside are not limited. At this time, the supporting platform is located at one end of the first guide rail 211 and located at the point a, and the centers of the frame structures 222 of the quarter circles of the two moving portions 221 are also located at the point a.

The overall reverse process of the wire rewinding process is a wire unwinding process, and is not described herein again.
A comparison of the fully retracted state of the cable 3 with the fully extended state of the cable 3 is shown in fig. 5, where R represents the corresponding circle radius of the quarter-circle frame structure 222, i.e. the minimum winding radius, which is the minimum radius to which the cable can be bent without any damage; LX represents the distance moved by the moving part 221; LB represents the height at which the support platform 21 is raised; LB' represents the length of the fixed end of the cable 3 inside the take-up and pay-off device (i.e., the length of the cable inside the housing structure 6 before being taken up); s represents the exposed length of the cable. In this embodiment, when the fixed end of the cable 3 and the supporting platform 21 are located at the point a, the position of one end far away from the outlet 61 coincides. When the free end of the cable 3 is received in the outlet 61, the reception is completed, and thus, it is understood that S is 2LX + LB'. However, it should be noted that if the height of the housing structure 6 is sufficient, the height of the supporting platform 21 can be higher than LB, and if the height of the housing structure 6 is sufficient, the moving distance of the moving part 221 can be greater than LX, and the exposed part of the cable 3 can be accommodated in the housing structure 6 in the above case, but it is understood that 2LX + LB' is required to be greater than or equal to the cable length S. In the illustrated embodiment, the fixing portion 1 is disposed obliquely with respect to the support platform 21, which reduces the width required for the housing structure 6, but it is understood that the fixing portion 1 may be disposed vertically with respect to the support platform 21 if the width of the housing structure 6 is sufficient. From this, it can be seen that the height at which the support platform 21 is raised, the distance by which the moving portion 221 moves, and the angle at which the fixing portion 1 is inclined with respect to the support platform 21 can be specifically set according to the length of the cable 3 and the height and width of the housing structure 6.
The take-up and pay-off device further comprises a power part 5 which is arranged in the connecting part 4 and used for providing power for the lifting part 2 and the translation part 22. As an example, the power unit 5 includes a first motor connected to the lifting unit 2, the moving unit 221 and the roller unit 223 for simultaneously controlling the movements of the lifting unit 2, the moving unit 221 and the roller unit 223. As another example, the power part 5 includes a second motor, a third motor and a fourth motor, wherein the second motor is connected with the lifting part 2 for controlling the movement of the lifting part 2; the third motor is connected to the moving part 221, and is used for controlling the movement of the moving part 221; the fourth motor is connected with the roller part 223 and is used for controlling the roller part 223 to move.

As an example, the charging pile further includes an angle sensor, which is installed on at least one roller of the roller set 228 close to the outlet 61 of the housing structure 6 of the pay-off and take-up device, when the external force applied to the cable 3 is greater than a preset external force value, the roller rotates, and when the rotation angle is greater than a preset angle value, the angle sensor sends a power-on signal to the pay-off and take-up device to start the pay-off and take-up device to pay off. Fill electric pile and insert rifle charging process, take-up and pay-off are in the complete unwrapping wire state. It should be noted that the preset external force value and the preset angle value are set according to specific use requirements and specific parameters of the winding and unwinding device.
