In the time that the commutation cycle starts, controller 1 is controlled and is transferred cylinder 2, and tapered sleeve 3 is separated with the first tapered sleeve seat 51, and after then confirming to separate completely by displacement transducer 4, controller 1 drive motor 11 rotates.
In the time that motor 11 drives the rotation of revolution turnouts to the position of the first speed reducing switch 61, the first speed reducing switch 61 detects that the rear transmission reduce-speed sign of trolley 15 is to controller 1.Controller 1 is controlled motor 11 and is slowed down.Now, from the first speed reducing switch 61 to second place B, (position of rest for the first time commutates) motor 11 is in the full retard stage, and by controller 1 displacement calculating and speed, allows second place B (position of rest for the first time commutates) speed close to 0.Then, as shown in Figure 2, buffer stopper 7, by minor impact the second buffing pad 72, allows revolution turnout in leveling off to the state stopping, and now, approach switch 14 detects when buffer stopper 7 and the second buffing pad 72 are fitted, and sends and approaches stop signal to controller 1.Controller 1 control cylinder 2 advances tapered sleeve 3 in the second tapered sleeve seat 52 subsequently, and obtains completing this commutation cycle after the confirmation of displacement transducer 4.
