When the turntable 2 drives the slewing bearing 6 to rotate, the approach switch has a signal, the number of the steel balls 61 recorded by the counter is added by 1, and after one rotation, the number of the steel balls 61 is the detection number.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
