The working principle is as follows: penetrating a cable between the extrusion wheel and the conveyor belt 3, then rotating the screw 5 according to the diameter of the cable, wherein when the screw 5 rotates, the screw 5 drives the connecting block 6 to press downwards and simultaneously drives the top plate 4 to move upwards; when the joining block 6 moves downwards, the extrusion wheel 7 is driven to move towards the conveying belt 3 and extrude the surface of the cable, when the top plate 4 moves upwards, the conveying belt 3 is pushed upwards, the conveying belt 3 is extruded on the surface of the cable, and the conveying belt 3 is propped against by the top plate 4 at the moment, so that the conveying belt 3 can be stably attached to the cable, the contact area and the friction force between the conveying belt 3 and the cable are ensured, and the cable is smoothly pulled; before the cable is pulled, lubricating oil can be smeared between the top plate 4 and the conveyor belt 3, so that the smoothness of relative movement between the top plate 4 and the conveyor belt 3 is ensured, meanwhile, the abrasion between the top plate 4 and the conveyor belt 3 is reduced, and the service life is prolonged;
the rotating roller body 8 is arranged on the top plate 4, so that when the conveyor belt 3 moves along the top plate 4, sliding friction between the conveyor belt 3 and the top plate 4 is converted into rolling friction through the roller body 8, meanwhile, lubricating oil is coated on the roller body 8, the friction force is further reduced, meanwhile, the roller body 8 can be set to be in a shape with a small middle diameter and gradually enlarged diameters at two ends, the conveyor belt 3 can be extruded and sunken when the top plate 4 extrudes the conveyor belt 3, the contact area between the surface of a cable and the surface of the conveyor belt 3 is increased, and the friction force is ensured;
the end part of the shaft body 10 eccentrically rotates and penetrates through the connecting block 6, and is fixedly connected with an external motor, the motor drives the extrusion wheel 7 to rotate, so that the conveying belt 3 and the extrusion wheel 7 are both driving force, and the cable is pulled to move; when water adheres to the surface of the cable or primary pollutants are generated, the friction force between the cable and the conveyor belt 3 is reduced, so that a slipping phenomenon occurs between the cable and the conveyor belt 3, therefore, the telescopic plate 13 which can move in a telescopic manner is arranged on the extrusion wheel 7, the threaded sleeve 11 is rotated to rotate towards the telescopic plate 13, the chamfer on the threaded sleeve 11 extrudes the inclined surface 15 on the outer top telescopic plate 13, the telescopic plate 13 gradually extends out of the telescopic groove 12, the arc-shaped opening 14 on the telescopic plate 13 wraps the surface of the cable, the pressure of the extrusion wheel 7 on the cable is increased, and the effective friction effect of the extrusion wheel 7 on the cable is increased;
by arranging the rod body 16, when the threaded sleeve 11 is rotationally pushed towards the telescopic plate 13, the chamfer angle on the threaded sleeve 11 can cross the upper inclined plane 15 of the outer stable jacking telescopic plate 13, so that each telescopic plate 13 can synchronously jack out the telescopic groove 12, and the lengths of the telescopic grooves 12 extending out are the same, and the top plate 4 can be stably extruded on the surface of a cable;
when the traction device is placed on the ground, the stability of the vehicle body 1 needs to be considered, due to the fact that the cable is drawn, the cable has opposite traction force to the vehicle body 1, in order to prevent the vehicle body 1 from being pulled by reaction force of the traction force, an adjusting mechanism is arranged on the vehicle body 1, an adjusting screw rod 19 is rotated, when the adjusting screw rod 19 rotates clockwise on a box body 20, the adjusting screw rod 19 moves downwards, relative rotation between the adjusting screw rod 19 and a lifting plate 18 enables the lifting plate 18 to move upwards, the tip end position of the lower end of the adjusting screw rod 19 is inserted into the ground, meanwhile, a wheel 17 moves upwards through the lifting plate 18, the wheel 17 is erected on the vehicle body 1 in the air, the vehicle body 1 is fixed on the ground through the adjusting screw rod 19, and the stability of the vehicle body 1 is improved;
the elastic rod 24 is taken out of the insertion hole 23, the rotating shaft 22 is rotated, so that the adjusting screw rod 19 connected to the rotating shaft 22 inclines towards the cable traction direction, then the elastic rod 24 is inserted into the insertion hole 23, the relative rotation between the rotating shaft 22 and the fixed seat 21 is fixed again, and at the moment, the adjusting screw rod 19 is inserted into the ground in an inclined state, so that the vehicle body 1 can resist larger traction reaction force;
after the cable penetrates through the pipe body 26, the cable is laid on the conveyor belt 3, then clean water is injected into the ring body 27 by using an external pump body, and the water is discharged from the water spraying holes to clean substances attached to the surface of the cable; because some cables penetrate through the underground passage, pollutants in the passage are attached to the cables, if the cables are not treated in time, corrosive substances are attached to the surfaces of the cables or corrode the conductive cores in the cables, and the pollutants are attached to the surfaces of the cables, cracks or cracking points on the surfaces of the cables are not easy to see, and the cables are washed by clean water in time, so that the problems can be found in time and solved in time when the cables are released or wound;
cable intermediate position disconnection department, the junction passes through the pipe fitting and connects together, and the diameter is greater than the diameter that passes through of body 26, sets up body 26 and ring body 27 half and half for this reason, and the setting of elastic plate 25 both makes things convenient for the part of body 26 and ring body 27, can quick closure again, and half ring body 27's intercommunication can be realized fast to the cooperation of fixed orifices 28 and intubate 29 simultaneously.
