  • Measuring-robot device for fully mechanized coal mining face and automatic measuring system
    Patent number: 11435183
    Abstract: A measuring-robot device for fully mechanized coal mining faces and an automatic measuring system are provided. The measuring robot includes a suspension cage, a total station, a prism and an industrial computer. Firstly, the suspension cage with automatic leveling function is fixed on the top beam of a hydraulic support, then the total station and the industrial computer are fixed in the suspension cage, and finally the prism with a plug connector is installed under the base of the total station, forming a measuring-robot device. According to the fluctuations of the fully mechanized coal mining face, several measuring robots will be deployed along the fully mechanized coal mining face, and the adjacent measuring robots are line of sight to each other, forming the automatic measuring system covering the fully mechanized coal mining.
