The screw-type double-lift hoist is a device used for gate control in hydraulic engineering. It employs a double-lift point design to enhance stability and load-bearing capacity, making it suitable for complex environments with high flow rates and high pressure. ?
Structural Composition
It mainly consists of a motor, screw, transmission device, and frame. The core component is the threaded transmission structure between the screw and nut, which converts rotational motion into linear motion to achieve the lifting and lowering of the gate. ?
Features
?High Stability?: The double-lift point structure ensures that the two screw rods are parallel and perpendicular to the gate lifting lug axis, preventing equipment damage caused by uneven force distribution at a single point; ?
Wide Applicability?: Suitable for hydraulic and hydroelectric projects such as reservoirs, river dams, and hydroelectric power stations, as well as gate control in urban sewage treatment; ?
Safety Design?: Equipped with torque protection and travel limit devices, supports remote and on-site operation, and features opening indication and signal light prompts. ?
Installation and Maintenance
During installation, ensure the foundation is level and solid, the screw rod axis is perpendicular to the gate lifting lug axis, and the double-lift points are balanced; ?
Regularly inspect lubrication conditions, bolt tightness, and electrical connections. Initial operation requires no-load and load tests; ?
During maintenance, clean metal debris and re-lubricate. A major overhaul is recommended every 3-5 years.
