[0039] A method for detecting the surface flatness of a gate, which uses a device for detecting the surface flatness of a gate, comprising the following operation steps:

[0040] (1) Install the detection device for the surface flatness of the gate: two longitudinal slideways are symmetrically arranged on both sides of the upstream surface of the gate, a moving plate is symmetrically arranged in the two longitudinal slideways, a horizontal track is arranged in the middle of the moving plate, and elastic is installed in the horizontal track The pressure-sensitive box, the moving plate and the elastic pressure-sensitive box are respectively connected with the reel in the data meter above the gate through the lifting rope and the measuring rope, and the pressure sensor in the elastic pressure-sensitive box is connected with the data collector in the data meter through the data cable. connect;
