When the hydraulic ram 601 is not operating, the distance sensor 800 detects the driving module 300 at the same time as the sensor in the translation module 200 detects the driving module 300, and the hydraulic ram 601 is in a closed state.
When the length of the porcelain bushing is greater than the distance between the two sets of fixing assemblies 500, the hydraulic push rod 601 at one end is first actuated, so that the fixing assembly 500 connected with the porcelain bushing can move in a direction away from the other fixing assembly 500, thereby extending the distance between the two sets of fixing assemblies 500. Then, two sets of fixing assemblies 500 are respectively fixed at two ends of the porcelain bushing, and cleaning work is started. When the sensor in the translation module 200 detects the driving module 300, the distance sensor 800 cannot detect the driving module 300 because the distance between the fixing member 500 and the housing 100 is elongated. Therefore, the two sets of hydraulic push rods 601 are simultaneously given working instructions, so that one set of hydraulic push rods 601 near the porcelain bushing cleaning mechanism 407 begins to contract, and the other set of hydraulic push rods 601 begins to synchronously stretch. The rack 100 drives the porcelain sleeve cleaning mechanism 407 to integrally move towards the extended set of fixing assemblies 500, so that the moving stroke of the porcelain sleeve cleaning mechanism 407 is increased, and the compatibility of the cleaning device is improved.
