[0024] A conveying chain 21 is provided on one side of the bracket 1, and the conveying chain 21 includes a material blocking device 22 and a transport vehicle 23. The material blocking device 22 and the transport vehicle 23 are both arranged on the conveying chain 21, and a lifting and fixing plate 24 is arranged in front of the material blocking device 22; when the transport vehicle 23 transporting the engine 25 is blocked by the material blocking device 22, the lifting and fixing plate 24 below lifts the transport vehicle 23, and at this time the transport vehicle 23 no longer follows the conveying chain 21 to move forward, which is convenient for the flywheel torque machine to perform subsequent operations.

[0025] The bracket 1 is also provided with a lifting device, which includes a driving motor 26 and a linear driving device 29. The driving motor 26 is driven and connected to a synchronous shaft 32, and linear driving devices 29 used in conjunction with the synchronous shaft 32 are arranged on both sides of the synchronous shaft 32; the driving motor 26 drives the synchronous shaft 32, driving the linear driving devices 29 on both sides to rotate.
