Abstract

The invention provides a large-scale portal frame. The large-scale portal frame comprises two rails, two trolleys, two stand columns, a movable main beam and a connection beam. Two ends of the movable main beam are respectively erected on the stand columns and are connected to a lifting device. Upper ends of the two stand columns are connected by the connection beam. The large-scale portal frame also comprises at least two counterweight mechanisms, a connection beam adjustment mechanism and two suspention beams for fixing manipulators. The counterweight mechanism comprises a guide wheel group, a suspension cable and a counterweight block. The connection beam adjustment mechanism comprises at least one adjusting nut, at least one adjusting screw and an adjusting seat. The two suspention beams are symmetrically fixed to the movable main beam, one end of each one of the suspention beams is close to the center of the movable main beam and any one of the suspention beams is provided with a horizontal movement mechanism. The manipulators are connected to the suspention beams by the horizontal movement mechanisms. The large-scale portal frame satisfies span and height requirements and is suitable for 3D printing building extruding head arrangement.

Description

technical field [0001] The invention relates to a large gantry frame. Background technique [0002] 3D printing architecture is a building constructed by 3D printing technology. It is composed of a giant three-dimensional extrusion machine. The extrusion head extrudes building materials such as concrete to create foundations and walls for houses, and directly manufactures buildings. The indenter must be supported and moved by a gantry, so that the foundation and walls of the house can be printed at different positions and heights. [0003] The span of the gantry must be greater than the size of the building to be printed, at least 10m, and the height must be at least two or three stories high, so it is a large gantry. In the process of printing the building, the gantry needs to move along the guide rail as a whole , and the gantry needs to have a movable main beam that can be lifted and lowered, and the main beam must provide guide rails for the print head to move along the...
