Embodiment 1

[0037] Embodiment 1: This embodiment takes the construction of a thermal cooling tower in a certain power plant as an example. In order to ensure the cooling effect, the thermal cooling tower is a cylindrical structure with a hyperboloid shape, that is, the thermal cooling tower has a continuously variable section. In order to clarify the direction relationship, press It is necessary to set the xyz Cartesian coordinate system with the z-axis direction as the height extension direction of the printed cylinder structure 700, combined below Figure 1 to Figure 8 Describe the 3D printing device for the cylindrical structure of the present invention, which includes a height direction self-adaptive expansion device 200, a printing device 300 and a standard section lifting device 600 connected sequentially from bottom to top;

[0038] Such as figure 1 with image 3 As shown, the height-direction adaptive expansion device 200 includes a guide rail base 210 that is vertically arranged...

Embodiment 2

[0048] Embodiment 2: Combination Figure 1 to Figure 8 Illustrate the 3D printing method of cylinder structure of the present invention, concrete steps are as follows:

[0049] S101: if image 3 As shown, construct the underground foundation 100 of the 3D printing device, and fix the 3D printing device on the underground foundation 100;

[0050] S102: if Figure 5 As shown, the control command is sent to the 3D printing device through the power control system, and the guide rail beam 350 is controlled by the guide rail beam to drive the brake mechanism 380 to rotate around the center O in the annular plane between the inner guide rail beam 310 and the outer guide rail beam 320. Braking, the printing head 370 is controlled by the printing head driving brake mechanism 360 to perform linear movement and braking in the annular plane relative to the printing head guide rail beam 350, and the printing head 370 is made to perform telescopic movement in the vertical direction by con...

Abstract

The invention discloses a 3D printing device of a drum body structure and method, and relates to the technical field of building construction. According to the 3D printing device of the drum body structure and method, the problems that an existing 3D printing device is low in stability and low in positioning precision and printing efficiency are solved. The 3D printing device comprises a height direction self-adapting extending device, a printing device and a standard joint lifting device. The height direction self-adapting extending device comprises a guide rail base and a jacking mechanism capable of climbing or dropping along the guide rail base. An inner guide rail beam of the printing device is connected with the jacking mechanism through an inner supporting beam. An outer guide rail beam is connected with the jacking mechanism through an outer supporting beam. A printing head guide rail transverse beam can slide along rails of the inner guide rail beam and the outer guide rail beam. The standard joint lifting device comprises a frame structure, a lifting rotating driving mechanism and a lifting support frame. The 3D printing method comprises the following steps that a printing head is controlled to spray building materials in an annular plane between the inner guide rail beam and the outer guide rail beam for printing all section layers of a drum body structure, a hung base standard joint is installed at the top end of the guide rail base for extending the height of the guide rail base, and the drum body structure is printed layer-by-layer in the height direction.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a 3D printing device and method for a cylindrical structure. Background technique [0002] The degree of mechanization and automation of the traditional construction industry is low, and the development of the industry urgently needs transformation and upgrading. In recent years, the increasingly mature 3D printing technology has brought great changes and technological innovations to the labor-intensive construction industry. Architectural 3D printing technology uses printing intelligent control to make buildings one-time shape, with less construction consumables and process losses, while mechanization and automation Therefore, architectural 3D printing technology is an important means to realize the transformation and upgrading of the construction industry, and it is also an effective way to realize efficient, safe, digital, automated and intelligent construction o...
