Abstract
The inspection robot for thin coal seam can replace workers to make the daily inspection in fully mechanized mining surface. Based on the narrow and poor environment of thin coal seam, we designed a joint swing arm inspection robot, which is able to adapt to the unstructured terrain in a thin coal seam. The structure of the moving mechanism of the inspection robot has been designed. It can be realized that there are two DOF for moving on a single drive central axis through design of the shaft inside and shaft sleeve outside. The strength check and the modal analysis of the key parts of the moving mechanism such as the hollow shaft sleeve and the drive shaft, are made by Ansys Workbench. According to the analysis results, the maximum stress caused by internal load and external impact load is far less than the yield strength of the material. The modal shape diagram shows that, when the meshing frequency and the external excitation frequency are much less than the first-order natural frequency of the parts, there will be no resonance and noise. The analysis results show that the design is reasonable and reliable.
Highlights
In China, thin coal resources are rich and widely distributed, the reserves of which account for more than 20% of the national coal reserves
In view of the above requirements, we have developed an inspection robot with articulated swing arms and crawlers, which is adaptable to the terrain environment of fully mechanized working surface in thin coal seam
DESIGN FOR MOVING MECHANISM The moving mechanism of the inspection robot includes its joint swing arms, which are the main parts used for crossing obstacles [8, 9], and the sizes of which are determined by the maximum ability of crossing obstacles and its overall volume
Summary
In China, thin coal resources are rich and widely distributed, the reserves of which account for more than 20% of the national coal reserves. With the development of new mining technologies, new processes, mechanized mining mechanization and automation mining equipments, the automation and unmanned operation of the thin coal seam mining become an important research direction of mining industry at home and abroad. In the mining surface of thin coal seam, the working conditions are poor, the labor intensity is high and the production efficiency is low. In order to reduce the labor intensity of workers, it is urgent to research and design an inspection robot working in the thin coal seam to replace the workers to carry out the routine inspections [1]. In order to improve the safety level and reduce casualties, it is important to develop a visual inspection robot adapting to the environment of fully mechanized mining surface in the thin coal seam to replace the workers
