Embodiment
Now in conjunction with the accompanying drawings, structure of the present utility model and operation principle are further described.
Be contained in the axle head of energy storage camshaft 1 among Fig. 2 for switching-in spring 17, the energy storage camshaft is contained on the energy storage axle 2, cam 10 is housed on the energy storage axle, interior elastic cylindrical pin 5, outer elastic cylindrical pin 6 fixedly connected clutch covers 7 are passed through in bearing pedestal 3 backs that the energy storage axle passes on the supporting plate 9, cylindrically coiled spring 4 half fixed cover are on bearing pedestal, second half is enclosed within on the clutch cover, and circlip for shaft 8 is equipped with in the clutch cover end.Because releasing energy at switching-in spring, spring operating mechanism suitable overshoot energy must be arranged when carrying out closing operation, can guarantee that just circuit breaker reliably closes a floodgate, if the motion of reverse resilience takes place in switching-in spring because of resilience force, then make and corresponding energy storage camshaft, energy storage axle, cam generation gyration the position between cam and the combined floodgate roller 11 is changed.As shown in Figure 3, in case when between cam and the combined floodgate roller not being closely extruding, then by first win in succession 15, second win 16 in succession, interlock mutually will take place in output shaft 12, sincere sub 13 quadric chains that constitute of separating brake, sincere son of separating brake and separating brake semiaxis 14 snappings take place loosening, thereby it is not in place to cause closing a floodgate, the separating brake action of influencing then not in place of closing a floodgate will be if serious electric accident will take place in normal separating brake.In order to prevent the generation of above-mentioned accident, the technology that the utility model adopted is at the fixedly connected clutch cover in the end of energy storage axle, on clutch cover and bearing pedestal, assemble cylindrically coiled spring, the contraction and the relaxation principle of internal diameter when the forward and reverse rotation of the clutch cover that utilizes the cylindrically coiled spring internal diameter and match produces friction, the energy storage axle is embraced during the overshoot resilience in the switching-in spring making process, promptly limited the resilience force effect of switching-in spring, guaranteed that combined floodgate or separating brake are reliable.
When switching-in spring drive energy storage camshaft, energy storage axle, cam and clutch cover according to Fig. 1 in the K direction be seen as when rotating synchronously counterclockwise, the state that adequate friction between clutch cover and the cylindrically coiled spring makes cylindrically coiled spring be in to loosen, at this moment, do not produce self-locking between clutch cover and the bearing pedestal, do not influence the regular event of switching-in spring.When switching-in spring releases energy according to the solid line among Fig. 2 when moving to dotted line counterclockwise, see that from the K direction energy storage camshaft, energy storage axle, cam and clutch cover are also for motion counterclockwise, so cylindrically coiled spring also is in the state that loosens this moment.But when producing resilience after the switching-in spring overshoot, the switching-in spring that is dotted line position among Fig. 2 is seen as when driving energy storage camshaft, energy storage axle, cam and clutch cover and rotating along clockwise direction from the K direction, friction between clutch cover and the cylindrically coiled spring at this moment makes cylindrically coiled spring be in the state of contraction, cylindrically coiled spring is held clutch cover tightly, the energy storage axle can not turn round, so just limited the resilience force effect of switching-in spring, make and closely push between combined floodgate roller 11 and the cam, sincere son of separating brake and separating brake semiaxis closely fasten, and have guaranteed the reliability of separating brake.
