The aerial work mechanism 1 includes a working basket 11 and an arm structure. The sliding mechanism 2 includes a sliding trolley 21 and a slide rail 22. The slide rail 22 is installed on the work trolley 4 and is arranged along the travel direction of the work trolley 4. The sliding trolley 21 is slid on the slide rail 22. The upper end of the arm structure is connected to the sliding trolley 21. The working basket 11 is installed at the lower end of the arm structure. The lifting mechanism 3 is transmission-connected to the sliding trolley 21 and is used to drive the sliding trolley 21 to slide along the slide rail 22 so that the aerial work mechanism 1 is extended to the front of the work trolley 4, or retracted to the top of the work trolley 4. The arm structure is used to drive the working basket 11 to move in the inclined shaft space so that the working basket 11 reaches the specified position.

[0028] When the aerial work mechanism 1 is retracted to a position above the work trolley 4, the aerial work mechanism 1 is in a non-operating state. The lifting mechanism 3 fully lifts the sliding trolley 21 until the sliding trolley 21 reaches the rear end of the slide rail 22, and is locked by the upper locking mechanism 23 to limit the movement of the sliding trolley 21 and avoid the risk of safety accidents. In this state, the boom structure of the aerial work mechanism 1 is completely retracted into the work trolley 4, and the other working devices 41 of the work trolley 4 can operate freely.
