The existing tail rope winding and unwinding device adopts a movable guide wheel or guide roller as a wire distributor.

The one-to-four tail frame retracting and releasing rope control system according to claim 3 is characterized in that: The linkage assembly includes a sliding frame (25) fixedly connected to the side wall of the lower end of the plastic brush (24), the sliding frame (25) passes through the fixed cylinder (16) and is slidably connected thereto, the sliding frame (25) is clamped with an eccentric disk (26), the eccentric disk (26) is rotatably connected to the inner wall of the fixed cylinder (16) through a mounting shaft (27), the mounting shaft (27) is fixedly connected to a passive gear (28), and the passive gear (28) is meshed with a driving gear (29) fixedly connected to the output shaft of the second motor (20).
9. The one-to-four tail frame retracting and releasing rope control system according to claim 8, characterized in that: The sliding frame (25) includes a sliding block (2501) and a rectangular frame (2502) fixed to the inner end of the sliding block (2501). The fixed cylinder (16) is provided with a transverse sliding groove for the sliding block (2501) to slide transversely. The eccentric disk (26) includes an eccentric column (2601). The eccentric column (2601) passes through the rectangular frame (2502) and is slidably connected thereto.
10. The one-to-four tail frame retracting and releasing rope control system according to claim 1, characterized in that: When winding the wire tail rope, the following steps are included: Step 1: monitoring the real-time torque of the winding frame (4) through the torque sensor (6), and obtaining the real-time tension value of the real-time steel wire tail rope based on the real-time torque value; Step 2: When the real-time tension is lower than the set tension threshold range, the controller starts the first motor (8) to drive the winding frame (4) to wind the steel wire tail rope, thereby increasing the tension of the steel wire tail rope until the real-time tension reaches the set tension threshold range; when the real-time tension is greater than the set tension threshold range, the controller starts the first motor (8) to drive the winding frame (4) to release the steel wire tail rope, thereby reducing the tension of the steel wire tail rope until the real-time tension reaches the set tension threshold range; Step three, monitoring the real-time temperature of the guide ring (17) through the first temperature sensor (15), when the real-time temperature of the guide ring (17) is greater than the set temperature threshold, starting the second motor (20), the second motor (20) drives the fan impeller (19) to rotate, so that the external air enters the fixed cylinder (16) through the filter (21), and then is injected into the annular cavity (1701) of the guide ring (17), and finally discharged from the gap between the ball (18) and the spherical groove (1702), and the ball (18) and the wire tail rope are sprayed until the real-time temperature of the guide ring (17) is lower than the set temperature threshold.
