Description

Technical Field

[0001] The present invention relates to a construction machine, in particular to a frame structure of a 3D printer for on-site construction. Background Art

[0002] In existing technology, the construction of exterior walls, insulation, and exterior decoration for most buildings is typically carried out in separate steps. Exterior wall construction requires internal and external formwork, while insulation and exterior decoration require scaffolding. This results in complex construction procedures, long construction periods, and significant waste. Recent advances in digital technology have enabled some building components to be 3D printed in factories and then delivered for on-site assembly. However, this is not on-site printing and is still some distance from true 3D-printed buildings. Some buildings currently under construction on site face the following challenges: For example, the 3D printing head must be raised as the building height increases. Currently, no effective solution has been found, limiting the printing of only one or two floors, hindering the development of 3D printing. Another significant issue is that the cement slurry used in 3D printing is less fluid than that used in traditional cast-in-place methods, making it more difficult to transport. Furthermore, a series of issues, such as the simultaneous construction of water and electrical equipment, remain to be resolved, further improving the printing of buildings. Summary of the Invention

[0003] The purpose of the present invention is to address the shortcomings of the existing technology and provide a frame structure for an on-site construction house 3D printer that can elevate the 3D printing head as the height of the building increases, thereby reducing the cement slurry transportation distance.

[0004] The present invention is achieved through the following technical solutions: a frame structure of an on-site construction house 3D printer, comprising two symmetrically arranged columns connected by a plurality of standard column sections, characterized by a printing platform, a power and material storage platform, and a lifting mechanism; wherein:

[0005] The printing platform is an annular frame composed of a horizontal beam and a longitudinal beam. Each of the two horizontal beams is provided with a cavity that forms a movable pair with the corresponding column column. Holes for anchoring the horizontal beam to the column are provided on both longitudinal sides of the cavity. A base for mounting the side pulley group of the lifting mechanism printing platform is provided on the right side of the cavity. The upper surface of the horizontal beam is provided with a guide rail for the sliding of the 3D printing head carriage. The longitudinal beam is fixedly connected to both ends of the horizontal beam.

[0006] The power and storage platform is an annular outer frame composed of horizontal beams and longitudinal beams and an I-shaped inner frame composed of horizontal beams and longitudinal beams. The two horizontal beams of the annular outer frame are each provided with a cavity that forms a moving pair with the corresponding column row. Hole seats for anchoring the horizontal beams to the columns are provided on both longitudinal sides of the cavity. A base for installing the lifting mechanism power and storage platform side pulley group, and a base for fixing the elevator power unit are provided on the lateral left side of the cavity. The horizontal beams of the I-shaped inner frame are fixed on the two longitudinal beams, and the two ends of the two longitudinal beams are fixed on the horizontal beams of the annular outer frame. A base for installing a crane is provided on the longitudinal beams of the annular outer frame, and a guide rail for the transverse movement of the storage hopper is provided on the horizontal beams of the I-shaped inner frame.

[0007] The column is provided with a plurality of groups of anchor holes on both longitudinal side walls corresponding to the hole seats of the printing platform, and the power and storage platforms, and the top of the column is provided with a fixing seat for fixing the middle pulley group of the lifting mechanism;

[0008] The lifting mechanism includes a power unit composed of a machine base, a motor, a reduction gear box, a brake, and a winch drum, an intermediate pulley group, a pulley group on the printing platform side, a pulley group on the power and storage platform side, and a steel rope; the intermediate pulley group is fixed to the column, the pulley group on one side of the intermediate pulley group corresponds to the pulley group on the power and storage platform side, the pulley group on the other side of the intermediate pulley group corresponds to the pulley group on the printing platform side, and the winch drum of the power unit corresponds to the pulley group on the power and storage platform side;

[0009] The two rows of columns are symmetrically arranged and fixed on the ground. The printing platform, the power and storage platform are sleeved on the columns through their respective cavities, and the printing platform, the power and storage platform are fixed to the columns in turn through anchor bolts. The steel rope passes through the winch drum to the side pulley group of the power and storage platform, and then through the intermediate pulley group to the side pulley group of the printing platform.

[0010] Compared with the existing technology, the frame structure of the on-site construction house 3D printer proposed in the present invention has the following advantages: the present invention arranges the printing platform, power and storage platform in layers, and then lifts the lifting mechanism to lift the printing platform or the power and storage platform according to actual needs, thereby solving the problem of lifting the 3D print head for continuous printing and the problem of feeding, and achieving substantial progress.
