place the one end of pipeline 2 in the arc groove 53 on fixing base 52, stretching out of cylinder 54 piston rod drives the both ends of fixture block 55 and slides downwards at the surface of support column 51, thereby arc groove 53 on the fixture block 55 contacts with pipeline 2 and extrudes slipmat 56, and slipmat 56 receives the elasticity that the extrusion produced to drive fixture block 55 and presss from both sides tightly the one end terminal surface of pipeline 2, reaches the effect of fixed pipeline 2.

S1, firstly winding the optical fiber to be drawn on the outer surface of the take-up and pay-off roller 3, then stretching one end of the optical fiber to the conveying caterpillar 4104 on the lower end bracket 41 at one side of the tractor body 1, and clamping the optical fiber with the gap formed between the outer flange glue 4105 on the conveying caterpillar 4104, placing one end of the pipeline 2 in the arc groove 53 formed on the fixed seat 52 in the support frame 5, extending the piston rod of the cylinder 54 to drive the fixture block 55 to move downwards, simultaneously driving the two ends of the fixture block 55 to slide downwards on the outer surface at one side of the support column 51 until the arc groove 53 on the fixture block 55 is contacted with the outer surface of the pipeline 2, extruding the non-slip mat 56 by the pipeline 2, and clamping the outer surface of the pipeline 2 by the elastic force generated by extrusion of the non-slip mat 56;

s2, rotating the hand wheel 422, wherein the rotation of the hand wheel 422 drives the threaded rod 421 to rotate, and the rotation of the threaded rod 421 drives the fixing plate 42 to move downward along the inner wall of the sliding groove 423 on the outer surface of the threaded rod 421, so as to drive the upper bracket 41 and the transmission caterpillar 4104 to move downward until the transmission caterpillar 4104 at the upper end contacts with the outer surface of the optical fiber on the transmission caterpillar 4104 at the lower end;

s3, starting the servo motor 4, the rotation of the output shaft of the servo motor 4 drives the first gear 4101 in the lower end bracket 41 at one side of the tractor body 1 to rotate, the rotation of the first gear 4101 drives the connecting shaft 4102 to rotate, the rotation of the connecting shaft 4102 drives the second gear 4103 to rotate, the rotation of the second gear 4103 drives the transmission caterpillar 4104 to rotate, the other first gear 4101 engaged with the outer surface of the first gear 4101 drives the first gear 4101 in the upper end bracket 41 to rotate, thereby driving the other connecting shaft 4102 to rotate and driving the other second gear 4103 to rotate in the opposite direction, and the transmission caterpillar 4104 on the upper and lower brackets 41 is driven to rotate in different directions due to the different rotation directions of the second gear 4103;

s4, the optical fiber presses the outer flange glue 4105 along with the rotation of the transmission caterpillar 4104, and the lubricating oil in the cavity 4106 of the outer flange glue 4105 overflows through the capillary holes 4107, so as to moisten the outer surface of the optical fiber;

s5, the rotation of servo motor 4 output shaft drives third gear 4110 simultaneously and rotates, the rotation of third gear 4110 drives another third gear 4110 through belt 4111 and rotates, thereby drive transmission shaft 4109 rotates, the rotation of transmission shaft 4109 drives wire guide wheel 4108 to rotate, the rotation of wire guide wheel 4108 will move the optic fibre guide that goes up on wire guide wheel 4108 through conveying track 4104 and enter pipeline 2, the optic fibre lubricating oil that the optic fibre surface is infected with is convenient for optic fibre and is removed in pipeline 2.

The working principle is as follows: before the tractor body 1 is used, one end of an optical fiber wound on a take-up and pay-off roller 3 is stretched into a transmission crawler belt on a support 41 at the lower end of one side of the tractor body 1, the optical fiber is clamped with gaps between outer flange glue 4105 at two sides of the transmission crawler belt 4104, then a hand wheel 422 is rotated to drive a threaded rod 421 to rotate, the rotation of the threaded rod 421 drives a fixing plate 42 to move downwards on the outer surface of the threaded rod 421 along the inner wall of a sliding groove 423 until the fixing plate 42 drives a first gear 4101 on the transmission crawler belt 4104 on the support 41 at the upper end of one side of the tractor body 1 to be meshed with another gear, simultaneously drives the outer flange glue 4105 on the transmission crawler belt 4104 to be contacted with the optical fiber, then one end of a pipeline 2 is placed in an arc groove 53 on a fixing seat 52, the two ends of a clamping block 55 are driven by the extending of a piston rod of an air cylinder 54 to slide downwards on the outer surface of a supporting column 51 until the arc groove 53 on the clamping block 55 is contacted with the pipeline 2 so as to extrude an anti-skid pad 56, the anti-skid pad 56 is pressed to generate elastic force to drive the fixture block 55 to clamp the end face of one end of the pipeline 2;

after the pipeline 2 is fixed and the optical fiber is placed, the servo motor 4 is started, the rotation of the output shaft of the servo motor 4 drives the first gear 4101 in the lower end bracket 41 at one side of the tractor body 1 to rotate, the rotation of the first gear 4101 drives the connecting shaft 4102 to rotate, the rotation of the connecting shaft 4102 drives the second gear 4103 to rotate, the rotation of the second gear 4103 drives the transmission crawler 4104 to rotate, the other first gear 4101 meshed with the outer surface of the first gear 4101 drives the first gear 4101 in the upper end bracket 41 to rotate, thereby driving the other connecting shaft 4102 to rotate and driving the other second gear 4103 to rotate in the opposite direction, because the rotation direction of the second gear 4103 is inconsistent, the transmission crawler 4104 on the upper bracket 41 is driven to rotate in different directions, the outer flange of the transmission crawler 4104 is driven to extrude the optical fiber glue 4105 along with the rotation of the transmission crawler 4104, lubricating oil in the outer flange glue 4105 cavity 4106 overflows through the capillary 4107 and moistens the outer surface of the optical fiber;
