[0020] A pressure roller is fixedly installed on the left side of the inner wall of the bin body and below the through hole, and the pressure roller is located between the two squeezing rollers.

[0021] Specifically, the threshold value of the cable winding speed is set by the controller, the laser speed sensor monitors the cable winding speed in real time, and uploads the monitored cable winding speed value to the controller. When the uploaded cable winding speed value is greater than or equal to the threshold value of the cable winding speed, the controller operates the hydraulic push rod to move the squeezing roller downward quickly, thereby pressing the cable between the squeezing roller and the pressure roller, realizing automatic emergency braking.
