Directly Connected Screw Hoist

The direct-connected screw hoist is a mechanical device that directly drives the gate's opening and closing through a screw. Its core feature is the direct transmission of motor power to the screw, enabling the lifting and lowering control of the gate. The following is a detailed introduction:
Working Principle
The direct-connected screw hoist employs an electric drive method. The motor transmits power to the worm through a gearbox, which then drives the worm gear and nut to rotate. Ultimately, the linear motion of the screw drives the gate to open or close. This structure achieves a direct connection between the power source and the actuating mechanism, simplifying the transmission process. ‌
Structural Features
‌Compactness: Compact structure with a small footprint, suitable for engineering scenarios with limited space.
‌Safety: Equipped with an operating lever to enable the separation/engagement operation between the motor and the worm, enhancing flexibility in use.
‌Protection: Manual/electric interlock device ensures operational safety, preventing equipment damage caused by misuse. ‌
Applicable Scenarios
Primarily used for controlling flat gates in hydraulic engineering, such as reservoirs, rivers, and hydropower stations, where precise opening and closing are required. It features strong anti-damage capabilities and convenient installation. However, it is important to note that it is not suitable for prolonged overload or continuous operation. ‌
Installation Requirements
During installation, ensure the foundation plane is level and the screw axis is perpendicular to the gate lifting lug hole. Conduct trial runs to verify installation accuracy. After initial use, regularly maintain and lubricate components to extend service life.
