The utility model discloses a main changing sleeve pipe mounting storing frame and relates to a storing frame. Currently, when a main changing sleeve pipe is mounted and stored, a steel pipe scaffold needs to be erected, efficiency is low, and binding fixing stability and safety are poor. The main changing sleeve pipe mounting storing frame comprises a support and a plurality of horizontal beams arranged on the support. The horizontal beams comprise fixed horizontal beams and adjustable horizontal beams. A fixed horizontal beam and an adjustable horizontal beam form a main changing sleeve pipe storage base. The support comprises four stand columns on the four corners, a plurality of oblique columns connected obliquely with the four stand columns, a bottom plate arranged at the lower ends of the oblique columns and the stand columns and supporting beams arranged at the upper ends of the stand columns and the oblique columns. The supporting beams and the horizontal beams intersect perpendicularly. The lower ends of the oblique columns and the lower ends of the stand columns are connected with the bottom plate. The oblique columns are arranged on the inner sides of the adjacent stand columns. The upper ends of the oblique columns are connected with the supporting beams which are provided with a plurality of kidney-shaped grooves. The horizontal beams and the supporting beams are connected through fastening pieces which penetrate through the kidney-shaped grooves and are connected with the adjustable horizontal beams. According to the technical scheme, labor intensity is lowered, sleeve pipe placing stability is improved, using is convenient and reliable, and disassembling and conveying are convenient.
