PORTAL 3D PRINTER Russian patent published in 2022 - IPC E04B1/16 B25J9/08 

FIELD: construction and robotics.

SUBSTANCE: invention relates to the construction industry and robotics, namely to construction robotic systems, and can be used as an installation for autonomous layer-by-layer building up of building and structure structures and performing surface machining. The effect is achieved by the fact that the portal-type 3D printer contains two vertical columns, made with the possibility of moving along the rail guides and interconnected by a horizontal fixed beam, the rail guides are installed on the base of the printer, while on the vertical columns with the possibility of moving in the vertical direction, a transverse a beam on which a carriage with a print head fixed to it is fixed with the possibility of longitudinal movement, while the rail guides are equipped with an alignment system that contains washers, nuts and screws, the last of which are mounted in the base of the printer, while the vertical columns and the cross beam are equipped with V-shaped rail guides with an additional alignment system, and the movement of the vertical columns and the cross beam is carried out using carriages with rollers due to the drive and helical rack, while the additional system alignment contains a base with grooves in which a pair of wedges is installed with the ability to move with the help of adjusting screws, a lodgement is installed in the wedges with the help of grooves, and a V-shaped rail guide is installed on the lodgement, while the lodgement has a through groove through which a screw passes, pressing the V-shaped rail guide and the lodgement to the base.

EFFECT: invention allows extending the functionality, speeding up and simplifying the process of manufacturing and assembling the printer structure, increasing the versatility and applicability of the printer.
