Powder-sowing and crack-making intelligent machine arm assembled on cement-based material 3D printing system

Abstract

The invention relates to a powder-sowing and crack-making intelligent machine arm assembled on a cement-based material 3D printing system. The intelligent machine arm comprises a shoulder, an upper arm, an elbow, a lower arm and a wrist portion, wherein the shoulder, the upper arm, the elbow, the lower arm and the wrist portion are sequentially connected to form the mechanical arm. The intelligentmachine arm is characterized by further comprising a crack cutting device, wherein the intelligent machine arm is a bearing of the crack cutting device; the mechanical arm is capable of driving the crack cutting device to perform corresponding movement and rotation; the crack cutting device is installed on the wrist portion; the crack cutting device comprises a powder storage unit, a fine sand storage unit, spraying pumps, spraying pipelines, a U-shaped hollow tool bit, a motion sensor and a connecting flange; the rear portion of the crack cutting device is fixedly connected to the wrist portion through the connecting flange; the U-shaped hollow tool bit is installed on the front portion of the crack cutting device; the powder storage unit and the fine sand storage unit are arranged at the position, close to the connecting flange, in the crack cutting device by taking the center shaft of the crack cutting device as the center; and both the powder storage unit and the fine sand storageunit are sealed cavities.

Description

technical field [0001] The invention relates to an intelligent robot hand for spreading powder and making cracks assembled in a cement-based material 3D printing system, belonging to the field of 3D printing machinery and equipment. Background technique [0002] In recent years, with the rapid development of my country's major infrastructure and energy engineering construction, high hydropower slopes, road and railway tunnels, underground caverns, nuclear power plant foundations, nuclear waste storage, underground oil and gas storage, mineral development, shale oil and gas and Major projects such as geothermal development involve complex geological structures with faults and three-dimensional fracture network rock masses. Physical model test is one of the main research methods in the field of geotechnical engineering, and its basis is to prepare a physical model that can accurately characterize complex geological structures. Due to the existence of these discontinuous surfac...
