Traditional construction methods, using hand-operated hoists in conjunction with total stations, suffer from low positioning accuracy, time-consuming adjustments, and high risks associated with working at heights. Pressure steel pipes are typically used in the water diversion systems of hydropower stations, and high-precision positioning is essential during installation; otherwise, the overall structural safety and operational efficiency will be compromised. Traditional methods may involve hoisting equipment combined with manual adjustments, which are inefficient, lack sufficient accuracy, and pose safety hazards. Existing positioning devices have limitations, including a single adjustment dimension and poor pipe diameter adaptability. Utility Model Content
