Abstract
The invention provides an excavation device for multi-angle tunnel excavation in a two-dimensional similarity simulation test, and belongs to the technical field of excavation devices for similarity simulation tests. The excavation device comprises an adjustable fixed frame, a rotary mechanism, a left-right sliding frame, a front-back sliding frame, a motor, a spiral drill bit and a drive assembly, wherein the adjustable fixed frame is parallel to a to-be-excavated surface, and comprises a transverse beam, a fixed vertical beam, an adjustable vertical beam and a tightening screw; the rotary mechanism comprises a rotary platform, a vertical rotary connecting block and a horizontal rotary member which is used for driving the rotary platform to rotate on a horizontal plane; the horizontal rotary member comprises a frame body, a rotary shaft and a slide table, the rotary shaft is rotationally arranged on the frame body and is provided with threads, and the slide table sleeves the rotary shaft; the left-right sliding frame is glidingly arranged on the rotary platform; the front-back sliding frame is glidingly arranged on the left-right sliding frame, and is vertical to the left-right sliding frame; the motor, the spiral drill bit and the drive assembly are arranged on the front-back sliding frame. The excavation device has the advantages that the artificial excavation can be replaced, and various defects in artificial excavation can be relieved.
Description
technical field [0001] The invention relates to the technical field of excavation devices for similar simulation tests, in particular to an excavation device for multi-angle roadway excavation in two-dimensional similar simulation tests. Background technique [0002] Because the working face of the mining project is underground, and the mining technology of each mine is complex and changeable, according to the research, many mine disasters are inseparable from the overlying rock structure and other problems, and the overlying rock layer is in the blind spot of observation, and the observation of the disaster surface alone cannot To achieve satisfactory results, and cannot completely and accurately reflect the specific conditions and the rock movement caused by mining during the mining process. Therefore, my country has introduced physical similarity simulation experiments. In the process of mining research in my country, physical similarity simulation research still occupies a...
