Specific embodiments
[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0025] An anti-corrosion paint spraying device inside a pipeline includes a main beam 1, and the cross-section of the main beam 1 is rectangular. A first support structure 2 and a second support structure 3 are respectively provided at both ends of the main beam 1.
[0026] The first support structure 2 includes a first support foot 4 and a second support foot 5. The first support foot 4 and the second support foot 5 are both hinged to the same end of the main material beam 1, and the first support foot 4 and the second support foot 5 are vertically distributed. Since both the first support foot 4 and the second support foot 5 are connected in a hinged manner, both the first support foot 4 and the second support foot 5 can only be folded outward with respect to the main beam 1. When the first support foot 4 and the second support foot 5 are perpendicular to the main beam 1, both the first support foot 4 and the second support foot 5 cannot be further folded inward with respect to the main beam 1, ensuring the stability of the first support foot 4 and the second support foot 5. In order to adapt to different pipe diameters of different metal pipes, both the first support foot 4 and the second support foot 5 are adjustable. The first support foot 4 and the second support foot 5 include a main support column 6 and an auxiliary support column 7. The main support column 6 and the auxiliary support column 7 are telescopically connected, and a fixing bolt 8 is provided between the main support column 6 and the auxiliary support column 7 to fix the main support column 6 and the auxiliary support column 7 through the fixing bolt 8. In order to facilitate the expansion of the first support foot 4 and the second support foot 5, arc-shaped support feet 9 are provided at the ends of both the first support foot 4 and the support frame 25. In order to increase the friction of the arc-shaped support feet 9, a rubber surface 10 is provided at the arc surface of the arc-shaped support feet 9.
[0027] The second support structure 3 includes an adjustment base 11. A fixing bolt 8 is provided at the adjustment base 11, and the adjustment base 11 is fixed by the fixing bolt 8. The third support leg 12, the fourth support leg 13, the fifth support leg 14, and the sixth support leg 15 are fixedly arranged in a cross-shaped array on the adjustment base 11. The cross-section of the main beam 1 is rectangular. Correspondingly, the adjustment base 11 is integrally rectangular. When the two are sleeved together, it can ensure the stable translation of the third support leg 12, the fourth support leg 13, the fifth support leg 14, and the sixth support leg 15. The third support leg 12, the fourth support leg 13, the fifth support leg 14, and the sixth support leg 15 are of equal length. At the same time, since the first support leg 4 and the second support leg 5 are of equal length, the main beam 1 can be located at the central axis position of the metal pipe. In order to adapt to metal pipes of different diameters, the third support leg 12, the fourth support leg 13, the fifth support leg 14, and the sixth support leg 15 are all adjustable. The third support leg 12, the fourth support leg 13, the fifth support leg 14, and the sixth support leg 15 all include a main support column 6 and a secondary support column 7. The main support column 6 and the secondary support column 7 are telescopically connected, and a fixing bolt 8 is provided between the main support column 6 and the secondary support column 7. Through the fixing bolt 8, the main support column 6 and the secondary support column 7 can be fixed. Also, in order to facilitate the placement of this device into the metal pipe, arc-shaped support feet 9 are provided at the ends of the third support leg 12, the fourth support leg 13, the fifth support leg 14, and the sixth support leg 15. A rubber surface 10 is provided at the arc surface of the arc-shaped support feet 9.
[0028] A paint spraying machine head 16 is provided at the main beam 1. The paint spraying machine head 16 is located between the first support structure 2 and the second support structure 3. The paint spraying machine head 16 moves back and forth between the two to spray paint on the inner wall of the metal pipe. The main beam 1 passes through the paint spraying machine head 16. The paint spraying machine head 16 includes a machine head main body 17. The cross-section of the main beam 1 is rectangular. Correspondingly, a rectangular hole 18 is provided at the central position of the machine head main body 17, which enables the paint spraying machine head 16 to move stably on the main beam 1. Two pulleys 22 are provided on each of the four inner side walls of the rectangular hole 18. The outer wall of the machine head main body 17 is a cylindrical surface, and six paint spraying nozzles 20 are provided on the outer wall of the machine head main body 17. The six paint spraying nozzles 20 are evenly distributed in a circular array on the outer wall of the machine head main body 17. In order to continuously supply materials to the paint spraying machine head 16, a material pipe 19 is connected to the paint spraying machine head 16. In order to enable the paint spraying machine head 16 to move, a towing rod 21 is connected to the paint spraying machine head 16. Through the towing rod 21, the paint spraying machine head 16 can be pushed or pulled in, so that the paint spraying machine head 16 can move on the main beam 1.
