When the scraping belt 601 just contacts the deformation part of the inner wall of the pipeline, the scraping belt 601 can be bent, meanwhile, the support block 701 can be pulled by the rotating shaft of the scraping belt 601 to receive the downward pressing force, and the downward pressing support block 701 can bend the adjusting groove 702, so that the scraping belt 601 can be normally bent to pass through the deformation part of the inner wall of the pipeline.
As shown in fig. 3, when the scraping belt 601 with the clamping block 603 moves to the deformed position of the pipeline, since the applicator 8 includes the socket column 801 connected with the support block 701 and having an L-shaped structure, one end of the sleeving connection column 801 far away from the supporting block 701 is connected with a clamping piece 802, one end of the clamping piece 802 is provided with a rotating adjusting block 803 connected with the downward pressing adjusting column 604, the other end of the clamping piece 802 is provided with a clamping groove 804, a deflection column 805 with a side wall sleeved with a torsion spring is connected in the clamping groove 804, the outer side of the deflection column 805 is sleeved with a deflection block 806, so that the clamping block 603 drives the downward pressing adjustment column 604 to move towards the correction cylinder 1, the movable downward-pressing adjusting column 604 drives the rotating adjusting block 803 to deflect towards the clamping block 603, and then the deflected rotating adjusting block 803 drives the clamping piece 802 to move together, so that the movable clamping piece 802 can push the scraping belt 601 to clamp the deformed position, and the scraping effect of the scraping belt 601 is better.
And when the clamping piece 802 clamps, the clamping piece can drive the deflection block 806 to move together and cling to the scraping belt 601, at this time, the torsion spring can play a role of pressing the deflection block 806 on the scraping belt 601 all the time, even if the correction barrel 1 moves continuously, the shape of the scraping belt 601 at the deflection block 806 changes, the deflection block 806 pressing the scraping belt 601 can cling to the scraping belt 601 all the time (because the torsion spring exists, the torsion spring has a certain movement amount, and the torsion spring exists in the clamping groove 804, the torsion spring can only push the deflection block 806 to cling to the scraping belt 601, but cannot have other conditions) (the number of the deflection blocks 806 is provided with a plurality of deflection blocks, the size is small (the specific size is adjusted according to requirements, the size of the clamping piece 802 can be the same as or different from that of the deflection block 806, but the shapes of the two are the same), thus, the purpose of enabling the scraping belt 601 to move along the track of the pipeline deformation position can be met), namely, the dust at the pipeline deformation position is scraped by the movable scraping belt 601 (because the, which can pull the wiping tape 601, so that the wiping tape 601 can be sufficiently attached to the deformed portion without slipping between the holding piece 802 and the wiping tape 601).

When the clamping piece 802 deflects towards the direction of the clamping block 603, the pulling column 809 can be driven to move together, then the moving pulling column 809 can push the return spring seat 807 (a selectable spring) and extrude the return spring seat 807, so that the movement of the clamping piece 802 is not affected, and meanwhile, when the scraping belt 601 is deformed through a pipeline, the return spring seat 807 can reset, so that the scraping belt 601 is indirectly pushed to reset.

The structure in the measuring cylinder 3 detects the deformation thickness of the deformation position by detecting the movement amount of the adjusting block 5, when the adjusting block 5 moves, the length detector 304 and the tension spring 303 are pulled by the pull column 305, so that the tension spring 303 is gradually stretched, meanwhile, the length detector 304 starts to gradually move, and when the tension spring 303 is not stretched, the distance detected by the length detector 304 is the deformation amount of the inner wall of the pipeline.
Meanwhile, the tension spring 303 applies a force to the tension detector 302 during the process of being stretched, so that the tension detector 302 starts to detect the force, when the tension detector 302 detects that the force is not changed, the detected position reaches the maximum deformation position (time is required to be recorded during the detection), then once the tension spring 303 is reset, the tension detector represents that the tension spring starts to pass through the deformation position, when the force of the tension detector 302 starts to be reduced until the tension spring returns to the initial position, the tension spring represents that the deformation position is passed, the time is recorded at the moment, the time is added to the time recorded before, and the deformation length is known by looking at the moving distance of the correction cylinder 1 in the time.
