The device for preventing the cable in the bridge from being pulled off is characterized in that the belt transmission mechanism comprises a driving pulley (22) and a driven pulley (23), the driving pulley (22) is fixedly connected with an output shaft of the cleaning motor (21), the driven pulley (23) is fixedly connected to the outside of the cleaning drum (19), and a transmission belt (24) is connected between the driving pulley (22) and the driven pulley (23).
8. The operation method of the device for preventing the cable in the bridge from being pulled off as claimed in any one of claims 1 to 7, comprising the following steps:
step one, fixing a shell (3) on one side of a wire outlet of a junction box (1), enabling a cable (2) connected in the junction box (1) to penetrate through the device, and fixing a first limiting block (27) on one side, close to the junction box (1), of the cable (2).
And step two, one end of the pulled cable (2) is connected with the dismounting machine, and the dismounting machine is connected with the cable (2) to move back and forth in the operation process.
Step three, when the cable (2) is driven to be retracted by the dismounting machine, an output shaft of the cleaning motor (21) drives a driving belt wheel (22) to rotate, the driving belt wheel (22) drives a driven belt wheel (23) to rotate through a driving belt (24), and the driven belt wheel (23) drives a cleaning barrel (19) to rotate, so that a dust cleaning brush in the cleaning barrel (19) is driven to clean dust or dirt and the like adhered to the outside of the cable (2), and the dust or the dirt is prevented from entering the shell (3) along with the cable (2) and affecting devices in the shell (3);
fourthly, when the cable (2) is not wound well when being coiled, the total length of the cable (2) is shortened, at the moment, the disassembling and assembling machine drives the cable (2) to move, the cable (2) which is originally in friction connection with the friction layer (26) of the inner sliding cylinder (7) is dragged out of the shell (3), meanwhile, the cable (2) is connected with a limiting block I (27) and is driven to one side of the connecting seat (8), the connecting seat (8) extrudes the pressure spring I (9), the pressure spring I (9) contracts and drives the inner sliding cylinder (7) to slide to one side of the movable plate (4), the inner sliding cylinder (7) then drives the movable plate (4) to move towards the inner wall of one side of the shell (3), the pressure spring II (11) of the movable plate (4) is compressed under stress, the movable plate (4) drives the metal sheet (14) to be in contact with the electric contact point I (12) and the electric contact point II (13), and the electric contact point I (12) is communicated, the power supply circuit of the buzzer (5) is closed, and the buzzer (5) starts to sound to prompt a worker; meanwhile, the normally closed relay is powered off, so that a power circuit of the disassembling and assembling machine is disconnected, the disassembling and assembling machine stops working, and the cable (2) is prevented from being broken.
