Description

Technical fields:

[0001] This utility model relates to a gate opening and closing machine drive device based on relay signals. Background technology:

[0002] Gate hoists are devices used in various large-scale water supply and drainage, water conservancy and hydropower projects. They can control the lifting and lowering of various large and medium-sized cast iron gates and steel gates to achieve the function of opening and closing. Gate hoists include components such as motors, frames, and protective covers. They are driven by a screw pair through a three-stage reduction method to obtain greater output torque.
