[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] like Figure 1 As shown, the electromagnetic stabilization structure for the internal blowing process of hot-dip galvanized steel pipe includes a frame 1, a feeding assembly 2, a lateral displacement assembly 3, an internal blowing assembly 4, and a cooling assembly 5.

The lateral displacement assembly 3 is installed below the internal blowing assembly 4. The feeding assembly 2 is used to drive the galvanized steel pipe to move linearly, and the lateral displacement assembly 3 is used to drive the galvanized steel pipe to move laterally. The cooling assembly 5 is used to cool and collect the galvanized steel pipe after internal blowing. The lateral displacement assembly 3 can move the galvanized steel pipe in the feeding assembly 2 to the internal blowing assembly 4, and at the same time, it can also move the galvanized steel pipe in the internal blowing assembly 4 to the cooling assembly 5, connecting the entire internal blowing process in series, reducing manual labor and improving work efficiency.

The fixed platform 45 is provided, and the built-in electromagnetic coil controls the position of the fixed platform 45 adsorbing the galvanized steel pipe through the touch switch 452 to prevent it from shifting. This ensures the stability of the galvanized steel pipe during the internal blowing process, reduces the problem of uneven galvanization caused by the galvanized steel pipe sliding down or shaking itself, reduces the waste of manpower and material resources, improves work efficiency, and improves product quality. The touch switch 452 is existing technology and is a TC-TLC54-C type switch made of high-temperature resistant material.

[0039] like Figure 5 As shown, the linear motion module 42 includes a second rotary motor 421, a lead screw 422, and a moving platform 423.

The moving platform 423 has a threaded hole in the middle, and the lead screw 422 is threadedly connected to the threaded hole. The first connecting rod 43 is installed on the moving platform 423. The linear motion module 42 is set up to ensure the stability of the running trajectory of the inner blowing head 44 during the inner blowing process through the bracket 41 and the lead screw 422, reduce the unevenness of the zinc coating caused by the shaking of the inner blowing head 44, and improve product quality.

[0040] like Figure 6 As shown, the cooling assembly 5 is located on one side of the frame 1, including an input unit 51, an output unit 52, and a cooling pool 53.

The conveyor belt 54 connects the input unit 51 and the output unit 52, increases the continuity of production, improves production efficiency, and reduces manual labor.

[0041] like Figure 7As shown, the input unit 51 and the output unit 52 have the same structure. The input unit 51 includes a driving shaft 511, a driven shaft 512, multiple sets of transmission belts 513, and a third rotating motor 514.

The third rotating motor 514 is fixedly connected to one side of the cooling pool 53. The outer periphery of the driving shaft 511 is connected to the inner ring of each set of transmission belts 513, and the inner ring of each set of transmission belts 513 is simultaneously connected to the outer ring of the driven shaft 512. The driven shaft 512 is set inside the cooling pool 53. The input unit 51 reduces the danger and damage of galvanized steel pipes falling freely from the internal blowing assembly 4 into the cooling pool and splashing water. The protrusion 5131 stabilizes the relative position of the galvanized steel pipes on the input unit 51, improving production safety and product quality.

[0042] The working process of the electromagnetic stabilization structure in the internal blowing process of hot-dip galvanized steel pipes:

[0043] After the galvanized steel pipe is moved to the corresponding position by the feeding assembly 2, the lifting cylinder 31 pushes the platform 32 to move the support plate 34 upward, touching the trigger switch 452 and disconnecting the electrical connection of the electromagnetic coil. At the same time, the multiple first grooves 342 on the support plate contact and lift the galvanized steel pipe in the feeding assembly 2 and the internal blowing assembly 4 respectively. The cylinder 33 pushes the support plate 34 to slide along the slide groove 321, sending the galvanized steel pipe on the multiple first grooves 342 to the internal blowing assembly 4 and the input unit 51 respectively. The lifting cylinder 31 descends, driving the platform 32 to descend, so that the trigger switch 452 is in the normally open state, connecting the electrical connection of the electromagnetic coil, stabilizing the position of the galvanized steel pipe during internal blowing. The steel pipe is stably transported to the cooling pool 53 through the input unit 51 and the protrusion 5131, and then transported to the output unit 52 by the conveyor belt 54, completing the collection of galvanized steel pipe.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
