Rack structure of rail-type site 3D building printer

Abstract

The invention relates to a rack structure of a rail-type site 3D building printer. The rack structure comprises two rows of rail guides which are symmetrically arranged at a certain interval, operating mechanisms, a metal structure frame, a lifting mechanism and a balance component; the metal structure frame comprises symmetrically-arranged left and right support legs and a transverse beam, the lifting mechanism comprises a power component and a lifting component, the power component is composed of a motor, a reduction gearbox and a gear of an output shaft of the reduction gearbox, and the lifting component comprises a lifting body, a plurality of rollers and hinge pin seats. The balance component comprises a steel wire rope, a pulley and an additional weight, the rollers are installed onthe four walls of the upper and lower layers of the lifting body to form a moving pair together with a rectangular guide rail column of a frame stand column, the two ends of the transverse beam of themetal structure frame are hinged to hinge pin seats of a short beam of the lifting body through hinge pin shafts. The rack structure has the advantages that stress of the transverse beam is simplified into a simply-supported beam, supports at the two ends of the transverse beam only provide vertical restraining, no corner restraining is provided, no additional internal force can be generated on the transverse beam and the support legs, and stress improvement of the transverse beam and the support legs develops in the direction of light weight.

Description

technical field [0001] The invention relates to a building construction machine, in particular to a frame structure of a rail-type site 3D construction printer. Background technique [0002] In recent years, with the further development, research and development of 3D printing technology, it is more and more widely used in various technical fields, and the construction industry that was unimaginable in the past has also made remarkable progress. All components of cement products should be able to be 3D printed, and it is required not only to be able to print in the factory, but also to be able to print directly in outdoor venues. However, the current construction 3D printers often use large-scale gantry machine tools or large-scale cranes. Due to the asymmetry between the two and the load, they do not match and cannot meet the needs of the market. Especially, the construction printing on the site is almost blank. The market expects further breakthrough. Contents of the in...
