[0017] In order to more clearly illustrate the technical solutions of the embodiments of the utility model, the drawings required for use in the embodiments are briefly introduced below. Obviously, the drawings described below are some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0018] Please see Figure 1 , Figure 2 and Figure 4 The embodiment of the utility model provides a work platform with a rotating function for an aerial work vehicle, including a boom 1 connected to the lifting arm of the aerial work vehicle, a rotating mechanism 2 installed on the boom 1 and a work platform body 3, one end of the boom 1 is connected to the lifting arm of the aerial work vehicle, and the other end of the boom 1 is a free end, the work platform body 3 is a cage with a fence, which is arranged in parallel below the free end of the boom 1, the rotating mechanism 2 is arranged on one side of the upper end of the work platform body 3, the upper end of the rotating mechanism 2 is fixedly connected to the free end of the boom 1, and the work platform body 3 is suspended in parallel below the boom 1, specifically, the rotating mechanism 2 includes a base 21 and a worm gear machine 22, the base 21 is fixedly installed on one side of the upper end of the work platform body 3, the worm gear machine 22 is arranged on the base 21, and the rotating shaft 23 of the worm gear machine 22 is arranged longitudinally and upward. Extension, a flange 24 is provided at the top of the rotating shaft 23, which is fixedly connected to the free end of the boom 1 through the flange 24, the rotating shaft 23 of the worm gear machine 22 is perpendicular to the working platform body 3, and the working platform body 3 is suspended parallel to the lower part of the boom 1 through the worm gear machine 22, the rotating shaft 23 is an output shaft connected to the worm gear in the worm gear machine 22, and a second rotating handle 29 connected to the worm is provided on the outer side of the worm gear machine 22, and rotating the second rotating handle 29 can drive the working platform body 3 to rotate around the rotating shaft 23 of the worm gear machine 22, when it is necessary to adjust the orientation of the working platform body 3, the staff can rotate the second rotating handle 29 forward or reversely according to the adjusted orientation, and use the worm gear machine 22 to drive the working platform body 3 to rotate parallel to the left or right around the free end of the boom 1 to expand the working space or working range.

[0019] Please continue to see Figure 1 or Figure 2 In order to further expand the working range of the working platform body 3, a slide rail 4 is arranged in parallel on one side of the upper end of the working platform body 3, and the slide rail 4 is extended to the left and right ends of the working platform body 3. A card slot matching the slide rail 4 is arranged on the above-mentioned base 21, and the base 21 is mounted on the slide rail 4 through the card slot. The slide rail 4 and the base 21 can slide relative to each other. When performing high-altitude operations, the staff can push the working platform body 3 to move horizontally along the left and right sides of the base 21 according to the working space or needs to expand the working space. In use, in order to facilitate the staff to lock the working platform body 3, a positioning pin 27 that can penetrate into the card slot of the base 21 is arranged on the outer side wall of the base 21. The positioning pin 27 is threadedly connected with the base 21 for limiting the base 21.
