Embodiment Construction

[0017] The specific steps of the automatic flaw detector probe replacement method of the present invention are:

[0018] 1. Manually park the flaw detection trolley where the probe of the automatic flaw detector is to be replaced in the service area of ​​the automatic flaw detector, and select the WinCC computer operation mode in the automatic flaw detector operating computer as "local operation".

[0019] 2. Close the water valve of the automatic flaw detector.

[0020] 3. Lift the probe of the automatic flaw detector that needs to be replaced on the flaw detection trolley separately, and unplug the wire plug of the probe.

[0021] 4. Use the hex wrench to remove the fixing screws of the probe and the frame, and place the screws in the order of removal.

[0022] 5. After unplugging the water pipe connecting the coupling water main pipe and the probe, use a 1-meter-long string to pass it through the probe support frame, and tie one side to the head of the unplugged probe wire...

Abstract

The invention provides a replacing method for a probe of an automatic flaw detector. The method comprises selecting 'local operation' as the WinCC computer operation mode, closing a water valve, individually raising a to-be-replaced probe, pulling out a probe lead plug, dismounting the probe and a frame fixing screw by using a wrench; pulling out a water pipe connecting a coupling agent water main pipe and the probe, using a fine rope with the length of 1 m to penetrate a probe supporting frame, tying one end at the pulled-out probe lead plug head, and lifting the old probe plug out of the supporting frame; installing a new probe on a probe support, connecting with the coupling agent water pipe, and connecting with a probe plug; adjusting the distance between the probe surface and the to-be-detected detection surface by adjusting the screw; opening the flaw-detector water valve; and calibrating the probe by using a calibration test block, and selecting 'remote operation' as the WinCC computer operation mode. The probe replacing method is simple, practicable and convenient in operation, is capable of shortening the replacing time by 20 min or more, helps to greatly improve work efficiency and satisfies requirement of on-site production rhythm.

Description

technical field [0001] The invention belongs to the field of steel plate flaw detection equipment, and in particular relates to a method for replacing a probe of an ultrasonic automatic flaw detection machine. Background technique [0002] With the aging of the automatic flaw detector equipment, the original method of replacing the probe of the ultrasonic automatic flaw detector causes the problem of probe scratching and probe support frame during the process of probe removal and installation, and the problem of probe scratching and probe support frame is solved on average. It takes 10 minutes, and the replacement speed is slow, which affects the production rhythm. Contents of the invention [0003] The invention provides a method for replacing a probe of an ultrasonic automatic flaw detector, aiming at shortening the replacement time of the probe of the automatic flaw detector and improving operation efficiency and production rhythm. [0004] For this reason, the solutio...
