Turning tool

The invention relates to the technical field of self-inspection before starting of large rotary equipment, in particular to a self-inspection tool for equipment such as a wind driven generator, and particularly relates to a turning tool. Comprising a rack, a plurality of driving motors are arranged on the rack, the driving motors are matched with a rotary inner gear ring through a transmission structure and drive the rotary inner gear ring to rotate, and the rotary inner gear ring drives a turning sleeve used for being in butt joint with a rotating shaft piece to coaxially rotate. The driving motor is adopted to drive the rotary inner gear ring to rotate and drive the barring sleeve to rotate, so that the barring operation is achieved, the overall tool is smaller in size and simpler in structure, can be flexibly arranged in a cabin of the wind driven generator, and is more convenient to use and more accurate in control. 本发明涉及大型回转设备启动前自检技术领域，尤其涉及到风力发电机等设备的自检工装，具体涉及一种盘车工装。包括机架，机架上设置有若干驱动电机，驱动电机通过传动结构与回转内齿圈配合并带动
