Matched three-dimensional physical model test robot system

Abstract

The invention relates to a matched three-dimensional physical model test robot system, which comprises two major parts including a three-dimensional physical model test and a matched robot. The outer part of the matched three-dimensional physical model test robot system is a reaction frame; at least one cube framework surface of the reaction frame adopts the following arrangement that at least two mutually parallel rectangular large steel plates are arranged between upright posts in opposite arrangement; at least one row of small rectangular steel plates are arranged between the two adjacent rectangular large steel plates; a rock body model is arranged inside the reaction frame; a vertical loading system, a horizontal left and right loading system and a horizontal front and back loading system are arranged between the reaction frame and the rock body model; the matched robot mainly comprises a robot body; an anchor rod support system and a grouting system are arranged in a matched way; a cutter disc is arranged on the top end of the head of the robot body; at least one group of support boots and at least one group of driving wheels are arranged on the robot body; a robot operation and control system is connected with the driving wheels through an operation and control pipeline. The system provided by the invention has the advantages that the surrounding rock evolution rule of the roadway digging and work face stoping can be accurately shown, and a reliable test measure can be provided.

Description

technical field [0001] The invention belongs to the technical field of a three-dimensional physical model test device for rock mechanics, and in particular relates to a matching three-dimensional physical model test robot system. Background technique [0002] With the development of the social economy and the needs of the national economy, the construction of underground mines and tunnels has shifted to the deep, and the research focus of rock mechanics has increasingly shifted to the underground. In the fields of mining engineering and hydropower engineering, the length, span and buried depth of underground roadways are also increasing. Therefore, the stress adjustment process and stability of the surrounding rock caused by roadway excavation under complex geological conditions become more important, while on-site surrounding rock monitoring requires more manpower, material and financial resources, and the workload is large and the cycle time is large. However, the change a...

Problems solved by technology

Manual excavation is time-consuming and laborious, and the effect of roadway formation is not good. The method of pre-embedded cylinders is divided into taking out the cylinders before loading to form a roadway and pushing out the cylinders to form roadways during the loading process. The former is far from the actual excavation process on site. Large, the latter is difficult to achieve when the stress is high and multiple roadways are interlaced

In the 3D simulation of coal mining face mining, manual and simple mechanical excavation are basically used, which is inconsistent with the actual excavation process, and it is impossible to realize coal cutting and mining with a certain inclination angle.
