[0028] In the existing production of threaded pipes, the conveying device used lacks stability and is prone to the rolling of the pipe body during the conveying process of the threaded pipe, resulting in corresponding radial displacement and affecting the docking with the equipment of the next threaded pipe production process.

[0029] As Figures 1 to 4 shown, a conveying device for the production of threaded pipes disclosed by the present utility model realizes a wrapped conveying effect during the conveying of threaded pipes through the mutual cooperation of a plurality of arc-shaped support seats 10, and ensures the stability during the conveying of threaded pipes by driving all sprockets 14 to rotate synchronously in three groups through three chains 3.

[0030] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0031] As Figures 1 to 4 shown, a conveying device for the production of threaded pipes includes a support structure 1; there are a plurality of support structures 1, and the plurality of support structures 1 are horizontally aligned and arranged at equal intervals, and adjacent two support structures 1 are fixedly connected through a connecting plate;

[0032] The support structure 1 includes an arc-shaped support base 10; at both ends and the middle position of the concave surface of the support base 10, support arms 11 are provided. At the free ends of the three support arms 11, rotatable friction wheels 12 are provided. On each friction wheel 12, a sprocket 14 fixedly connected coaxially is provided, and the diameter of the sprocket 14 is smaller than the diameter of the friction wheel 12.

[0033] The sprockets 14 at the same setting positions on all the support bases 10 are rotationally connected in synchronization through a chain 3; the rotating shafts of the three sprockets 14 on the outermost support base 10 are respectively connected to the output shafts of three driving motors 13.

[0034] In the practical application of the present utility model, first, the pipe body of the threaded pipe is placed on the outermost support base 10. At this time, the three friction wheels 12 on the support base 10 are respectively in contact with the pipe body of the threaded pipe, forming a wrapped support. Further, the three driving motors 13 are turned on. The three driving motors 13 respectively drive the three chains 3 to rotate through the three sprockets 14 connected thereto. Further, the three chains 3 respectively drive the other sprockets 14 connected thereto to rotate. Since a sprocket 14 fixedly connected coaxially is provided on each friction wheel 12, all the friction wheels 12 rotate synchronously. At this time, the pipe body of the threaded pipe starts to move step by step on this conveying device driven by the friction wheels 12, realizing the conveying of the threaded pipe.

[0035] In another embodiment of the present utility model, as Figure 2 shown, at both ends of the convex surface of the support base 10, support plates 2 in contact with the ground are provided.

[0036] In this embodiment, the driving motor 13 is a servo motor, and the driving motor 13 is connected to a driving controller.

[0037] In this embodiment, the driving controller controls the driving motor 13 to maintain the same rotational speed to realize the synchronous rotation of all the friction wheels 12 and improve the conveying stability of the threaded pipe.

[0038] In another embodiment of the present utility model, as Figure 3 shown, the outer surface of the friction wheel 12 is provided with protrusions for contacting the surface of the threaded pipe.

[0039] In this embodiment, the driving motor 13 is fixed on a mounting frame, and the mounting frame is fixed on the concave surface of the support base 10.

[0040] In another embodiment of the present utility model, as Figure 4 shown, the support base 10 is semi-circular arc-shaped.

[0041] In this embodiment, the semi-circular arc-shaped structure design of the support base 10 realizes the wrapped support for the threaded pipe.

[0042] In this embodiment, a rubber layer for anti-slip is provided at the bottom end of the support plate 2.

[0043] The anti-slip rubber layer design helps to improve the stability of the device when it is set on the ground.
