Portal type building 3D printer achieving integral and alternate lifting

Abstract

The invention discloses a portal type building 3D printer achieving integral and alternate lifting and belongs to the technical field of constructional engineering 3D printing. The two ends of a supporting frame of the printer are connected with Z-axis slide rails, so that a portal type supporting structure is formed. The bottom of each Z-axis slide rail is connected to a Y-axis rail through a Y-axis drive mechanism and a guide wheel in a sliding manner. A pulley a and a pulley b are connected to each Z-axis slide rail in a sliding manner, wherein each pulley a and each pulley b are provided with locking mechanisms. The pulleys b are connected with the two ends of an X-axis slide rail. A sliding trolley is driven by an X-axis drive motor to be connected with the X-axis sliding rail in a sliding manner. The sliding trolley is connected with a printing mechanism. The Y-axis drive mechanisms, the X-axis drive motor, an alternate lifting mechanism, the printing mechanism and the locking mechanisms are connected with a control system. The portal type building 3D printer achieving integral and alternate lifting has the beneficial effects that the Y-axis rails can be prolonged, and outstanding advantages existing when an ultra-long building or a townhouse building is printed; in addition, the portal rail manner is adopted, so that the mechanism and the structure are greatly simplified, the manufacturing cost is greatly reduced, and conversion of a scientific and technological achievement is facilitated.

Description

technical field [0001] The invention relates to a gantry-type 3D printer, which belongs to the technical field of construction engineering 3D printing. Background technique [0002] After the 3D printers for construction projects came out and were put into use, there is a defect that only one set of houses can be printed for one installation, while for townhouses, it needs to be disassembled and assembled before construction. The length of the printer’s printing house is limited by the design length of the printer. If the length of the printer is too long, the design, manufacture and cost of machinery, structure, transmission, etc. have a great impact, which affects the practicability and economy of this type of equipment. Contents of the invention [0003] In order to solve the defects existing in the prior art, the object of the present invention is to provide a gantry-type overall alternate lifting building 3D printer for printing super-long buildings or row buildings. ...
