[0003] At present, the assembly of hydrogen fuel cell systems adopts the form of a turnover trolley. For the driving method of the turnover trolley, one is by shaking a handwheel; the other is by motor drive; both have their own advantages and disadvantages. The method of shaking a handwheel has the advantages of low cost and convenient use; the disadvantages are time-consuming and laborious, and low efficiency. The method of motor drive has the advantage of greatly improving labor efficiency, and the disadvantage is that it requires switch point control, which has certain requirements and limitations for on-site layout.

One side of the turntable has a welded and fixed connecting piece, and the connecting piece is buckled outside the turnover frame and fixed by screws. Both ends of the base have two symmetrical support frames. The side of the turntable away from the connecting piece has a fixed shaft, and the fixed shaft is embedded in the top of the support frame to realize rotational connection with the support frame, and both sides of the support frame have symmetrical reinforcing ribs;

[0007] One turntable is provided with a handwheel assembly, the other turntable is provided with a transmission assembly, and a voice control panel is installed on top of the transmission assembly.

When the servo motor drives the lower driving wheel to rotate, the upper toothed ring is driven to rotate synchronously through the chain, so that the upper toothed ring drives the turntable to rotate through the fixed shaft, thereby driving the tipping frame to tip.

[0010] Preferably, the voice control panel is internally provided with a main board, a microphone, a signal receiver, and a signal transmitter. The staff issues a voice command, which is received by the microphone for instruction transmission, thereby controlling the rotation of the servo motor.
