[0050] After installation is completed, the rotary drive source 31 is started to drive the turnover frame 12 and the gearbox thereon to reset to a horizontal state, and then the connecting sliding plate 22 is reset to release the product and hoist out through the telescopic drive source 24.

[0051] During the above working process, whether the gearbox is clamped to the position is detected by the action sensor of the telescopic drive source 24 during the clamping process of the clamping assembly 2, and the overturning assembly 1 can only perform the overturning action after clamping to the position, so that the safety of production is ensured.
