[0011] Figure 3 is the rotating working principle schematic diagram of the vehicle-mounted lifting maintenance platform. DETAILED DESCRIPTION

[0012] The embodiments of the utility model will be further described below in combination with the drawings.

[0013] As Figure 1 shown, the embodiment comprises a vehicle body 1, a scissor lift 2 and a lifting platform 3, the bottom of the scissor lift 2 is fixed on the vehicle body 1, the lifting platform 3 is fixed at the top end of the scissor lift 2, and the lifting platform 3 is controlled to be lifted and lowered by the scissor lift 2. Above the lifting platform 3 is a working platform 5, and the lifting platform 3 and the working platform 5 are connected through a bearing 4. In order to balance, the bearing 4 is located at the center position of the lifting platform 3 and the working platform 5, and the working platform 5 can rotate horizontally relative to the lifting platform 3.

[0014] As Figure 1 and Figure 2 shown, the front end edge and the rear end edge of the working platform 5 are respectively provided with a front fence 7-1 and a rear fence 7-2 hinged to the working platform 5, both of which can be folded flat on the working platform 5. In order to prevent eversion, the outer side of the hinged part of the front fence 7-1 and the rear fence 7-2 to the working platform 5 is provided with a support block 7-5, so that the maximum angle of the upward turning of the front fence 7-1 and the rear fence 7-2 is 90 degrees. The left side edge and the right side edge of the working platform 5 are respectively provided with a left fence 7-3 and a right fence 7-4 hinged to the working platform 5, both of which can be turned 180 degrees in the vertical direction. In actual construction, the above-mentioned front fence 7-1, rear fence 7-2, left fence 7-3 and right fence 7-4 are all turned upward to 90 degrees and fixedly connected to each other to form a rectangular fence.
