Existing conveying structures generally use simple conveyor belts or conveyor rollers for transport. When the diameter of the steel pipe changes, the contact points between the simple conveyor belt or conveyor roller and the steel pipe of different diameters are different, which affects the transport operation and changes the stability of the steel pipe during the transport process. Summary of the Invention

[0019] This utility model provides an embodiment, such as Figure 1As shown, a precision steel pipe conveying device includes a platform 1, on which two adjustable bases 2 are provided that can move away from or close to each other. The platform 1 is provided with two parallel linear guide rails. The two adjustable bases 2 are equipped with linear motors that cooperate with the linear guide rails. Each of the two adjustable bases 2 is provided with a set of supporting conveying mechanisms 3. Each set of supporting conveying mechanisms 3 includes a set of conveying roller assemblies 310, a support frame 320 rotatably connected to the conveying roller assembly 310, a base 330 fixedly connected to the support frame 320, and a drive assembly 340 fixed on the base 330 and drivenly connected to the conveying roller assembly 310. The side of the two bases 330 that is close to each other is rotatably connected to the platform 1.

[0023] In this embodiment, the telescopic guide 314 includes a guide hole coaxially arranged with the active roller 312, and a guide rod coaxially connected to the driven roller 313 is movably arranged in the guide hole. By adjusting the distance between the active roller 312 and the driven roller 313, it can adapt to steel pipes of different diameters, so that the active roller 312 and the driven roller 313 can have good contact with the surface of the steel pipe and achieve the support and limiting effect.

[0024] The cross-section of the guide hole can be an equilateral triangle or a regular quadrilateral, and the cross-sectional shape of the guide rod is the same. In the case of the rotating drive roller 312, it can drive the driven roller 313 to rotate.

[0025] Specifically, the base 330 is provided with a slide groove 332, and the adjusting member 331 includes a slide block 333 movably disposed in the slide groove 332 and a first telescopic member 334 fixed in the slide groove 332 and connected to the slide block 333.
