DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-4 , the present invention provides a technical solution: a steel anti-corrosion coating spraying device, comprising a base 1 and a plurality of clamping and driving mechanisms 20;

[0031] The upper surface of the base 1 is laterally fixedly connected with a device seat 2, and the upper surface of the device seat 2 is vertically rotatably connected with a rotating disk 3, and the top of the rotating disk 3 is laterally fixedly connected with a connecting block 7 whose length matches its diameter, and the top of the connecting block 7 is provided with a slide groove 8 along its length direction, and the inside of the slide groove 8 is provided with a sliding seat 11 movable along its length direction, and the top of the sliding seat 11 is fixedly connected with a vertically arranged fixing ring 15, and the inner ring surface of the fixing ring 15 is laterally rotatably connected with a rotating ring 16, and a plurality of clamping and driving mechanisms 20 are all provided on the inner ring surface of the rotating ring 16;

[0032] The structures of multiple clamping and driving mechanisms 20 are all the same, and one of the clamping and driving mechanisms 20 includes a connecting ring block 201 which is fixedly connected to the inner ring surface of the rotating ring 16 and is semi-annular, and the inner surface of the connecting ring block 201 is slidably connected to a sliding block 202 along its inner contour direction, and the inner side of the sliding block 202 is fixedly connected to multiple cylinders 206 which are perpendicular to each other, and the other ends of the multiple cylinders 206 are fixedly connected to a connecting plate 207, and the front and rear ends of the inner surface of the connecting plate 207 are fixedly connected to an external connecting frame 208, and the insides of the two external connecting frames 208 are both rotatably connected to power rollers 209, and the middle part of the inner surface of the connecting plate 207 is fixedly connected to an inner connecting frame 210, and the inner end of the inner connecting frame 210 is fixedly connected to multiple contact rollers 211 whose inner ends are located on the same horizontal line, and the two power rollers 209 and the multiple contact rollers 211 are connected by a transmission belt.

The pipe material can be clamped by the conveyor belt mechanisms on the multiple clamping and driving mechanisms 20 to make the pipe material in a horizontal state. Then, the multiple conveyor belts start running synchronously to drive the pipe material to move in the horizontal direction. When the pipe material moves to the position of the arc spray gun 23, the arc spray gun 23 will start and spray the outer surface of the pipe material, so that a layer of anti-corrosion coating is formed on the outer surface.

[0042] When the second motor 13 is running, the rotation of its output shaft will drive the threaded rod 9 fixedly connected to it to rotate, and the threaded sleeve 10 on the outer surface of the threaded rod 9 will move along the length direction of the threaded rod 9, and then synchronously drive the sliding seat 11 fixedly connected to the threaded sleeve 10 to move horizontally. The multiple guide rods 12 can support and guide the sliding seat 11, thereby improving the stability of the sliding seat 11 during movement.

[0043] A second gear ring 17 coaxial with the rotating ring 16 is fixedly connected to its outer surface, a mounting groove is transversely opened on the same side surface of the sliding seat 14, a third motor 18 is transversely fixedly connected to the inside of the mounting groove, and a second gear 19 meshing with the second gear ring 17 is fixedly connected to the outer surface of the output shaft of the third motor 18.

[0044] When the third motor 18 is running, the second gear 19 on the output shaft surface thereof will drive the second gear ring 17 meshing therewith to rotate, and then synchronously drive the rotating ring 16 fixedly connected thereto to rotate.
