[0028] To make the objectives, features, and advantages of the present utility model more obvious and understandable, the technical solutions in the present utility model will be clearly and completely described below with reference to the accompanying drawings in the specific embodiments of the present utility model. Obviously, the embodiments described below are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this patent.

[0029] This specific embodiment provides a feeding platform for spiral finned tubes, as Figures 1-9 shown; it includes a groove steel frame 1, the groove steel frame 1 is arranged along the Y-axis direction, a through groove 3 is provided inside the groove steel frame 1, and the two ends of the through groove 3 are respectively the inlet end and the outlet end of the spiral finned tube 2; the spiral finned tube 2 can enter the groove steel frame 1 from the left inlet end of the through groove 3 and flow out of the groove steel frame 1 from the right outlet end of the through groove 3, so as to realize the feeding of the spiral finned tube 2.

[0030] A plurality of through holes 13 are formed in the bottom of the through groove 3, and every two through holes 13 form a group. The linear center distance dimension between the two through holes 13 in the same group is greater than the width dimension of the through groove 3. By setting the linear center distance dimension between the two through holes 13 in the same group, it can be ensured that the two through holes 13 in the same group are arranged obliquely and are distributed on both sides of the center line of the through groove 3. Ball seats 14 are installed in the through holes 13, and the universal balls 4 are rotatably installed in the ball seats 14. By setting the universal balls 4, the surface of the universal balls 4 can be brought into contact with the outer wall of the spiral finned tube 2.

The second square beam 36 and the first square beam 35 are firmly connected by a second long bolt 37. By adjusting the position of the second square beam 36 inside the first square beam 35, the layout height of the channel steel frames 1 and the bottom plate 5 can be adjusted, so as to adapt to the spiral finned tube 2 production lines with various height requirements; and by providing the second long bolt 37, the connection stability between the first square beam 35 and the second square beam 36 can be enhanced.

[0036] The working principle of the present utility model is as follows:

[0037] The spiral finned tube 2 enters from the left inlet end of the through groove 3 of the channel steel frame 1. When the spiral finned tube 2 passes through the through groove 3, the surface of the spiral finned tube 2 comes into contact with the universal balls 4, thereby ensuring that the surface of the spiral finned tube 2 is not damaged. When the spiral finned tube 2 is completely arranged in the through groove 3, the quality inspection personnel can bring the magnetic suction head 12 at the bottom of the probe rod 11 into contact with the surface of the spiral finned tube 2, so as to magnetically attract the spiral finned tube 2 with the magnetic suction head 12. By rotating the hand wheel 28, the height of the second support plate 8 can be increased, thereby lifting the spiral finned tube 2 and making the spiral finned tube 2 come out of the through groove 3. The quality inspection personnel can fully observe the surface of the spiral finned tube 2, so as to ensure that the processing quality of the spiral finned tube 2 meets the production requirements; if there are scratches or damages on the surface of the spiral finned tube 2, the quality inspection personnel can move the first support plate 6 through the handle 17 to arrange the current spiral finned tube 2 above the bottom plate 5, so as to facilitate the next spiral finned tube 2 to enter the through groove; at this time, the quality inspection personnel can remove the damaged spiral finned tube 2 from this platform and perform reprocessing, so as to ensure the production quality of the spiral finned tube 2.

[0038] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be apparent to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
