Abstract

The invention discloses a 3D printing trough wall robot and a construction method thereof, including a hydraulic walking system, a material storage system, a stirring and extruding system, a three-dimensional right-angle printer, a nozzle and a control system, and the like. The three-dimensional right-angle printer is located on the side of the hydraulic walking system. The control system controls the mixing and extrusion system to mix and extrude concrete, and at the same time controls the three-dimensional right-angle printer and nozzles to print three-dimensional concrete. After the printing along the groove is completed, the next working face is excavated along the wall along the groove to form a gob-side entry. The invention realizes the 3D printing of the tunnel wall along the gob-side roadway without templates, and the 3D printing robot can walk by itself, which improves the mechanization degree and construction speed of underground concrete operations, and is suitable for fields such as coal mines, metallurgical mines, underground engineering, and tunnel engineering. .

Description

technical field [0001] The invention belongs to the technical field of coal mining machinery and coal pillar-free mining, and in particular relates to a 3D-printed trough wall robot and a construction method for gob-side digging. Background technique [0002] Pillarless mining is an important research direction of green mining. Pillarless mining includes gob-side entry without pillar mining and gob-side entry without pillar mining. Gobside entry retention can save a trough for each working face, recover coal pillars, and ease the tension in mining. At the same time, it can realize Y-shaped ventilation to solve the problem of gas exceeding the limit in the upper corner, and turn losses into profits, improve quality and efficiency, and Safe and efficient production is of great significance. Due to the impact of two mining operations on the gob-side retaining roadway, it is difficult to preserve the roadway and it is very difficult. Gob-side excavation bears the impact of on...
