In practical application, the laser spraying device 6 melts and sprays the composite material 15 on the defect of the pipe 16 to be repaired after receiving the composite material, and the conventional laser spraying device 6 in the market in the field is adopted, so that the spraying process needs only to be satisfied.
In this embodiment, in order to improve flexibility of the device, a 45-degree rolling connection frame 7 for connecting the guide roller 5 and the roller support frame 4 is disposed between the guide roller 5 and the roller support frame 4, and the installation angle of the 45-degree rolling connection frame 7 in this embodiment means that when the guide roller 5 is installed, an included angle between a plane on which the guide roller 5 is located and a cross section of the pipe 16 is 45 degrees.
In the prior art, the installation angle of the guide roller 5 is generally right angle with the direction of the pipeline, the guide roller 5 can only do fixed encircling rolling motion on the surface of the pipeline, so that the guide roller 5 is too unilateral in repair, and if other damaged positions on the pipeline are required to be repaired, workers are required to manually move, in the invention, the connection frame of the guide roller 5 is changed to 45-degree deflection, so that the guide roller 5 can do encircling motion on the surface of the pipeline and can do linear motion along the extending direction of the pipeline, the guide roller has flexibility in repair, and different damaged positions of the pipeline can be more comprehensively taken care of, so that the flexibility and the practicability are higher. In addition, in order to improve the stability during movement, each roller support frame 4 is provided with two guide rollers 5, and the guide rollers are respectively positioned at two ends of the roller support frame 4.
In this embodiment, in order to facilitate the movement of the repairing device on the pipeline, a driving mechanism is disposed in the middle of the two roller support frames 4 corresponding to the symmetrical group of connecting beams 3, and the driving mechanism comprises a motor 8, a transmission gear 9, a driven gear 10, a synchronous belt 19 and a driving roller 11, wherein the sizes of the rotating gear 9 and the driven gear 10 are the same, and synchronous movement is performed through the synchronous belt 19.
The motor 8 is fixed on the roller support frame 4 through the fixing base, the transmission gear 9 is connected at the output shaft end of the motor 8, the driving rollers 11 are two and are all fixed on the roller support frame 4 through the connecting frame, the transmission gear 9 is coaxially connected with one driving roller 11, and the driven gear 10 is coaxially arranged with the other driving roller 11. The two driving rollers 11 are consistent with the guide roller 5 in size and installation angle, and the two driving rollers 11 are respectively positioned at two sides of the synchronous belt. The diameter of the driving roller 11 is not smaller than the diameters of the two gears.
In practical application, the motor 8 drives the transmission gear 9 to rotate, the synchronous belt 19 rotates with the transmission gear to drive the driven gear 10 to transmit, and finally, the two driving rollers 11 roll synchronously, so that the whole frame body moves on the pipeline 16 together. The two driving rollers 11 are distributed on two sides of the synchronous belt 19, and the size and the installation angle of the driving rollers 11 are consistent with those of the guide rollers 5, so that the running stability is improved.
In this embodiment, in order to facilitate the repair process applicable to pipelines with different diameters, a pushing mechanism is disposed between each roller support frame 4 and the connecting beam 3, and the roller support frames 4 are driven to reciprocate back and forth along the radial direction of the annular frame 1 by the pushing mechanism so as to adapt to pipelines with different diameters.
The pushing mechanism on each roller support frame 4 comprises a plurality of groups of electric push rods 12, and the guide rollers 5 on the whole roller support frame 4 can be abutted against the outer wall of the pipeline through arranging the plurality of electric push rods 12, so that the installation stability of the repairing device is ensured. The roller support frame 4 is driven to freely reciprocate relative to the connecting beam 3 by the electric push rod 12, and the guide roller 5 is driven to freely move relative to the pipeline by the telescopic electric push rod 12 so as to adjust the distance between the guide roller and the pipeline, thereby realizing the repair operation of different pipeline diameters.

If the pipe is corroded over a larger area, and more composite material is needed, the composite material wound around the material winding shaft 17 is thicker, and the chuck 18 with the diameter matching the diameter is replaced. The laser spraying device 6 is positioned on the inner side of the other material winding shaft 17, and when the repair is needed, the laser spraying device 6 melts the composite material 15 on the corresponding material winding shaft 17 and then sprays the composite material to the position where the repair of the pipeline 16 is needed.
