6. A steel structure performance detection method comprising the steel structure performance detection device of any one of claims 1 to 5, characterized by comprising the steps of:
the method comprises the following steps that firstly, a crane is used for hoisting a mobile detection machine onto an I-beam, two flange plates of the I-beam are vertical to a horizontal plane, four idler wheels at the bottom of the mobile detection machine are arranged on a web plate of the I-beam, two side plates of an installation frame are located between the two flange plates of the I-beam, and clamping plates on the mobile detection machine are located on two sides of the I-beam respectively;
step two, executing the operation of mutually drawing the two clamping plates together through the industrial touch panel computer, sending a control signal for controlling the two clamping plates to be drawn together by the industrial touch panel computer in the process, transmitting the control signal to the control module through the first signal transceiver module and the second signal transceiver module in sequence, controlling the starting of the adjusting motor by the control module, driving the rotating shaft to rotate for a certain number of turns by the adjusting motor so as to draw the two clamping plates together, and ensuring that the guide wheel on the inner side of the clamping plate is in contact with the flange plate of the I-steel;
step three, the operation of the forward detection of the mobile detector is executed through the industrial touch panel computer, in the process, the industrial touch panel computer sends out a control signal for controlling the forward detection of the mobile detector, the control signal is transmitted to the control module through the first signal transceiver module and the second signal transceiver module in sequence, the control module receives the signal and then controls the driving motor to start, the ultrasonic probe is electrified to start detection, the driving shaft is driven to rotate by the driving motor so as to realize the forward movement of the mobile detector, the ultrasonic probe transmits the detected information to the ultrasonic phased array flaw detector through the second signal transceiver module and the first signal transceiver module in sequence in the forward movement process of the mobile detector, and the ultrasonic phased array flaw detector analyzes and processes the detection signal received by the ultrasonic probe and displays the analysis result on a liquid crystal display screen of the ultrasonic phased array flaw detector;
step four, after the detection of the I-steel is finished, the operation that the two clamping plates are away from each other is executed through the industrial touch panel computer, in the process, the industrial touch panel computer sends out a control signal for controlling the two clamping plates to be away from each other, the control signal is transmitted to the control module through the first signal transceiver module and the second signal transceiver module in sequence, then the control module controls the adjusting motor to start, the adjusting motor drives the rotating shaft to rotate towards the direction opposite to the rotating direction of the adjusting motor in the step two, so that the two clamping plates are away from each other, and the guide wheel on the inner side of each clamping plate is separated from the flange plate of the I-steel;
and fifthly, hoisting the mobile detection machine to the ground by using a crane to complete the detection of the I-steel.
