A emergency power equipment design of direct current full hydraulic tunnel for coal mine

In the case of a coal mine power failure, the hydraulic equipment is stuck and cannot be reset in the working state. There is a problem of potential safety hazards, and to meet the short-term operation requirements of hydraulic equipment in the coal mine roadway where there is no power source. The hydraulic tunnel emergency power device is used to solve the confusion encountered in the process of underground coal mine construction. In the device design process, the explosion-proof lead-acid battery pack and inverter were optimized, the working principle of the inverter was analyzed, and the hydraulic pump station, control console and walking mechanism were designed. Finally, the feasibility and the feasibility of the hydraulic power device were verified through experiments. Promotion should be the case.
