[0002] At present, when the contact network is powered off in the inspection depot of the EMU, it is often necessary to remove and hang the ground wire, so as to ensure that the residual electricity in the roof maintenance operation area can be reliably grounded after the isolating switch is powered off and isolated, thereby ensuring that there is no risk of electric shock to the workers who climb to the top in the maintenance operation area. In the prior art, the ground wire is usually removed and hung by manually hanging the ground pole, which is not only time-consuming and laborious, but also may cause great harm to the human body.

When the hook head of the ground pole is connected to the contact network, its resistance is too large. When the contact network short-circuits and sparks, it is difficult to effectively conduct a large current to the ground, which greatly reduces the work efficiency of grounding and conduction. Therefore, how to scrape and peel off the dirt on the contact network while avoiding manual work to ensure the stability of grounding and conduction is a problem that people in this field need to solve.

[0037] At present, when the contact network is powered off in the inspection depot of the EMU, it is often necessary to remove and hang the ground wire, so as to ensure that the residual electricity in the roof maintenance operation area can be reliably grounded after the isolating switch is powered off and isolated, thereby ensuring that there is no risk of electric shock to the workers who climb to the top in the maintenance operation area. In the prior art, the ground wire is usually removed and hung by manually hanging the ground pole, which is not only time-consuming and laborious, but also may cause great harm to the human body. In addition, since the contact network is exposed to the air for a long time, a thicker oxide layer and dirt layer are easily generated on its surface. When the hook head of the ground pole is connected to the contact network, its resistance is too large. When the contact network short-circuits and sparks, it is difficult to effectively conduct a large current to the ground, which greatly reduces the work efficiency of grounding and conduction. Therefore, how to scrape and peel off the dirt on the contact network while avoiding manual work to ensure the stability of grounding and conduction is a problem that people in this field need to solve.
