Catwalk erection traction system and control method thereof

The catwalk erection traction system comprises a supporting structure, a traction mechanism, a winding device, a distance detection device and a control device, and the supporting structure comprises two oppositely-arranged towers and a bracket arranged between the two towers; the traction mechanism comprises a pilot cable arranged between the two towers in a stretching mode and a traction device fixedly installed on the pilot cable, and a traction part is arranged at the lower end of the traction device and used for pulling a catwalk bearing cable to move; the winding device is used for winding or releasing the pilot cable so that the pilot cable can move in the length direction of the pilot cable; the distance detection device is used for detecting the distance between the traction device and the bracket; and the control device is electrically connected with the winding device and the distance detection device. Potential safety hazards in the catwalk erecting process can be reduced, and the catwalk erecting
