Problems solved by technology

There are two problems during this period. One is that due to the high density of cement raw materials and the large amount of extrusion per unit time, the load on the print head is much larger than the range of traditional 3D printers. The large load can easily cause the vibration of the print head, which affects Processing accuracy, so in order to ensure the processing accuracy of the existing construction industry 3D printing system, the size of the printable workpiece is limited, which cannot meet the needs of the construction entity
The second is that due to the inherent characteristics of bulky and overweight building entities, it brings a lot of risks to the transportation and assembly process, which leads to the high cost of 3D printing building entities, which seriously limits the application of 3D printing technology in the construction industry. application and promotion

Embodiment 1

[0063] Such as Figure 1-12 shown.

[0064] An on-site concrete 3D printing system includes two ballastless tracks 1 , two sets of X-Z direction movement mechanisms 2 and one set of Y direction movement mechanisms 3 .

[0065] The ballastless track 1 includes two seamless steel rails 1-1, one X-direction rack 1-2 and a plurality of sleepers 1-3; the X-direction rack 1-2 is assembled inside the seamless steel rail 1-1 ;

[0066] The X-Z direction movement mechanism 2 includes a mobile platform 2-1, front and rear side columns 2-2, left and right side columns 2-3 and a Z direction movement mechanism 2-4; the mobile platform 2-1 is composed of a plurality of modular units, Each modular unit includes a car body 2-1-1, an axle 2-1-2, a wheel 2-1-3, an X direction motor 2-1-4 and an X direction gear 2-1-5. direct fixed connection between them; the wheel 2-1-3 has a flange structure feature, and is symmetrically assembled under the car body 2-1-1 through the wheel shaft 2-1-2, and...

Embodiment 2

[0073] As in the on-site concrete 3D printing system described in Example 1, further, the mobile platform 2-1 can be modularly assembled according to the requirements of load and size. For modular units, see Figure 4 ;

Embodiment 3

[0075] As in the on-site concrete 3D printing system described in Example 1, further, the first connector 3-4 and the second connector 3-15 have similar structural features, the difference lies in the installation groove and installation The directions of the hole arrays are alternated;

Abstract

The invention relates to a field operation type concrete 3D printing system and an assembling method thereof. The field operation type concrete 3D printing system comprises two ballastless tracks, twoX-Z direction movement mechanisms and a Y direction movement mechanism. According to the system and the method, a size standard is established by utilizing the ballastless tracks, so that field positioning of large-scale concrete 3D printing systems is realized; through modularized combination of a wheel type moving platform, requirements for different loads and different printing sizes are realized; and the assembling method is reasonably designed, the system is capable of effectively counteracting influences, caused by mechanism deformation due to large load, on system work while ensuring the precision. The field operation type concrete 3D printing system is simple in structure, safe, reliable and low in environment requirement, and can be widely applied to various construction sites.

Description

technical field [0001] The invention relates to a concrete 3D printing system for on-site operation and an assembly method thereof, belonging to the technical field of 3D printing. Background technique [0002] The traditional definition of 3D printing technology refers to a technology based on digital models, using bondable materials such as powdered metal or plastic, and using layer-by-layer printing to construct objects. Expanding printing materials to building materials such as cement has formed the 3D printing technology of the construction industry. The 3D printing of the construction industry originated from a free-form component that is suitable for layer-by-layer accumulation and selective solidification of cement materials proposed by American scholar Joseph Pegna in 1997. 3D printing plays an extremely important role in realizing informatization and greening of the construction industry. Compared with traditional construction methods, it is more environmentally fr...
