[0002] In the operation and maintenance process of hydropower stations, tool cabinets are key facilities for carrying various professional tools. Their transportation and storage have long relied mainly on manual operations. Although this traditional model is widely used in the industry, with the increase in the demand for improved operation and maintenance efficiency of hydropower stations, labor cost control, safe working environment and refined warehouse management, the traditional tool cabinet storage method has the following disadvantages: high labor intensity. Hydropower station tool cabinets are usually loaded with a large number of heavy and precise professional tools. The manual handling process is laborious and easily causes excessive physical exhaustion of operators. Long-term repetitive operations may lead to an increase in the risk of occupational diseases and a decrease in work efficiency. In addition, it takes a long time to manually carry the tool cabinet to the designated location and adjust the stacking order.
