Building pipe conveying device

The invention provides a building pipe conveying device which comprises a bottom plate, and a plurality of sets of stand columns are arranged on the peripheral side of the bottom plate; the pressing plate assembly comprises a pressing shell, a clamping assembly arranged in the pressing shell and a pushing sliding rail for driving the clamping assembly to deform; a plurality of sets of openings are formed in the side wall of the pressing shell, and the clamping assembly extends from the interior of the pressing shell to the exterior of the pressing shell through the openings. The clamping assembly comprises two sets of clamping arms and a pushing unit, and the pushing unit changes the distance between the clamping arms under the action of the pushing sliding rail so as to be matched with the diameter of the pipe. The multiple sets of pressing plate assemblies are adjusted to be at intervals matched with the pipes and then placed in the stand columns to form the supporting faces, and the multiple layers of supp
