[0042] Two bottom boxes 43, disposed on both sides of the bottom end of the cleaning plate 41, for receiving dust and foreign objects swept from the surface of the suspension rail;

[0043] An inlay block 44, correspondingly disposed in the bottom box 43 and having an air flow channel, for forming a conveying path for dust and foreign objects swept from the surface of the suspension rail;

[0044] A collecting cavity 45, disposed in the end plate 42 and communicated with the air outlet cavities of the inlay blocks 44 on both sides. With such a design, through the end plate 42 welded to the outer side of the mounting bracket of the driven wheel 3 and the cleaning plate 41 welded to the inner surface of the end plate 42, during the rolling process of the driven wheel 3 assembled on the base 1 of the suspension rail type charging pile in this embodiment, the cleaning plate 41 and the bottom box 43 welded to the bottom end of the cleaning plate 41 can effectively clean the contact surface between the driven wheel 3 and the suspension rail, and the swept dust and foreign objects will directly fall on the open part above the inlay block 44 embedded in the bottom box 43, and then enter the collecting cavity 45 left by turning processing in the end plate 42 through the air flow channel provided in the inlay block 44 under the suction of the air flow.

[0045] It should be noted that brush hairs are processed on the vertical surface of the cleaning plate 41 close to the suspension rail and the arc surface of the bottom box 43 close to the suspension rail, which can have a certain additive effect on the cleaning effect.

[0046] In one embodiment, several inlets 431 for sucking dust and foreign objects are spacedly arranged on the arc surface of the bottom box 43 fitting the surface of the suspension rail. With such a design, by turning and processing several inlets 431 spacedly on the arc surface of the bottom box 43 fitting the surface of the suspension rail, a small part of the dust and foreign objects near the lower side of the suspension rail can be sucked into the collecting cavity 45 through air flow negative pressure, so as to effectively clean the contact surface between the suspension rail and the driven wheel 3.

[0047] In one embodiment, the collection assembly 5 includes a negative pressure box 51 and a collection box 52 which are arranged on the end face of the base 1 and stacked up and down.

[0052] In one embodiment, two cleaning assemblies 4 with the same structure are respectively provided on the outer side of one side of the driven wheel 3. The two cleaning assemblies 4 are communicated through a connecting pipe 8 and are separately arranged on both sides of the hanging rail.
