[0029] Reference Figure 1-Figure 3 According to an embodiment of the utility model, a high-efficiency steel pipe phosphating device includes a box body 11, in which a processing pool 12 is arranged. The phosphating of the steel pipe requires that the phosphating liquid in the processing pool 12 is at a certain temperature, so a heat pipe is laid in the processing pool 12.

[0030] In addition, the processing pool 12 is equipped with a supporting plate 13, and the supporting plate 13 is provided with a through groove 14 that passes through from top to bottom. Two rotating shafts 15 are rotatably connected in the through groove 14. The two rotating shafts 15 are connected by a wear-resistant belt 16, and also include a toggle mechanism for driving the rotating shafts 15 to rotate.

[0031] When the steel pipe is phosphating, the steel pipe will be located on the supporting plate 13, and at this time the staff can drive the rotating shaft 15 to rotate through the toggle mechanism and move the wear-resistant belt 16. At this time, the steel pipe located on the supporting plate 13 will move so that it can fully contact the phosphating solution in the processing pool 12, thereby accelerating the phosphating efficiency.

[0032] In the second embodiment of the high-efficiency steel pipe phosphating device, in order to facilitate the removal of the processed steel pipe located on the supporting plate 13, the supporting plate 13 is configured to be hinged in the processing pool 12, and the upper side of the box body 11 is connected to a No. 1 motor 18 through a bracket 17, and the No. 1 output shaft in the No. 1 motor 18 is connected to a winding wheel 19, and the end of the rope in the winding wheel 19 is connected to the right end of the supporting plate 13. When the No. 1 motor 18 is energized, the rope can be tightened through the winding wheel 19, thereby lifting the right end of the supporting plate 13. In order to prevent the steel pipe located on the supporting plate 13 from sliding off the left side of the supporting plate 13 during this process, a left baffle 20 is provided at the left edge of the upper side of the supporting plate 13.

[0033] In this embodiment, the shifting mechanism comprises a wheel groove which is open downwards and is provided in the carrier plate 13, a rotating shaft 15 extends into the wheel groove and a first gear 21 is mounted on the rotating shaft 15;

[0034] The box body 11 is provided with a No. 2 motor 22, and the end of a No. 2 output shaft extending from the No. 2 motor 22 is provided with a No. 2 gear that can mesh with the No. 1 gear;

[0035] When the right end of the supporting plate 13 swings to the lowermost side, the No. 1 gear 21 meshes with the No. 2 gear. At this time, the No. 2 motor 22 can drive the rotating shaft 15 to rotate by driving the No. 2 output shaft, and make the wear-resistant belt 16 move. When the wear-resistant belt 16 moves, it can move the steel pipe located on the supporting plate 13 to make it fully contact with the phosphating solution located in the processing pool 12.

[0036] In order to prevent the steel pipe on the supporting plate 13 from tilting and being difficult to remove, the upper side of the supporting plate 13 is also slidably connected to two side baffles 23 , and also includes an adjustment mechanism for controlling the front and rear positions of the side baffles 23 .

[0037] In this embodiment, the adjustment mechanism includes a threaded shaft 24 installed on the supporting plate 13, and two opposite sections of threads are processed in the threaded shaft 24, and the two sections of threads are respectively connected to the two side baffles 23. The staff can rotate the threaded shaft 24 to adjust the distance between the two side baffles 23 so that the steel pipe located on the supporting plate 13 will not be skewed (so that the steel pipe extends in the left and right directions, which is convenient for the staff to pick up the steel pipe).

[0038] Alternatively, a third motor for driving the side baffles 24 to rotate is disposed on the carrier plate 13 so that the spacing between the side baffles 23 can be electrically adjusted.

[0039] In addition, in order to facilitate the precipitation of the phosphating solution and to increase the service life of the phosphating solution, the lower side of the processing pool 12 is inclined to the lower right, and a chip collecting groove 25 is provided in the processing pool 12. The chip collecting groove 25 is arranged at the bottom of the processing pool 12, and a drainage hole is provided in the chip collecting groove 25.

[0040] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
