Due to the high shelves, relatively large quantities of goods can be stored, and the utilization rate of the upper three-dimensional space of the warehouse is high, but at the same time, higher requirements are placed on the overall and local safety and stability of the shelves. Existing monitoring equipment and inspection robots are difficult to quickly inspect evenly arranged shelves due to line of sight obstruction. In order to further improve warehouse safety and facilitate the inspection of goods, and to quickly carry out fire protection at high places in case of fire, a hanging rail robot and a method of using the same are proposed. A running track is configured between high-rise shelves, so that the hanging rail robot can move and lift between multiple high-rise shelves, so that the high-rise shelves can be monitored at the required height, and the fire-fighting box can be quickly connected in case of fire, and dry powder fire extinguishing treatment can be carried out on high-rise goods. It is suitable for safety monitoring and inspection work in warehouses with close spacing and many blind spots of vision. Summary of the invention
