Abstract
The utility model relates to an actuating device of a vacuum load-break switch, comprising a controlling shaft of the load-break switch, a motor and a gear set. The characteristics of the utility model are that the gear is sleeved on the controlling shaft, the end side of the gear is provided with convex gear teeth, a clutch cum is axially disposed on the controlling shaft via sliding sleeve, a return spring is arranged between the clutch cum and the controlling shaft, a round pushing wheel is arranged on the convex wheel, the round pushing wheel is positioned in the position in which the round pushing wheel can be pushed by a rocker-arm. When hand-motion switch control is needed, the rocker-arm inserts into the end portion of the controlling shaft, the round pushing wheel is pushed inwards, which enabling the clutch cum to separate from the engagement of the teeth of the convex wheel mounted on the end side of the gear. Then, the rocker-arm can easily rotate the controlling shaft to the position of switch-closing without influencing the portions of the gear set and the motor. The utility model has reasonable design, simple structure, and convenient operation, and can protect the working surface of the gear, thereby preventing damage of the facilities resulting from man-made forcible switch closing.
Description
Technical field:
The utility model belongs to the high-voltage switch gear field, particularly relates to the driving mechanism of a kind of vacuum load switch Central Shanxi Plain actuating on-load switch operating axis.
Background technology:
Existing vacuum load switch drives operating axis and is mainly motor-driven, and its structure comprises on-load switch operating axis, motor and gear train, and motor is given operating axis by the pitch wheel group with transmission of power, finishes feed motion; In the conventional art, also be provided with hand interface,, realize manual closing operation by hand arm so that when electrical fault in the operating axis end.All does not have the clutch structure of employing and realize electronic and manual on/off switch automatic switchover in existing switch, not only there is bigger resistance in closing by hand, and on/off switch locatees and can't determine very easily pitch wheel to be pulled bad, and mechanism is damaged.
Summary of the invention:
The utility model designs a kind of vacuum load switch driving mechanism electronic and that manually can automatically switch that has at the deficiency of prior art.
The technical solution of the utility model is as follows: a kind of vacuum load switch driving mechanism, comprise on-load switch operating axis, motor and gear train composition, it is characterized in that geared sleeve is located on the operating axis, gear face is provided with cam tooth, one clutch cam axially slides on the operating axis, be provided with back-moving spring between clutch cam and operating axis, clutch cam is fixed with the round wheel of a thrust through connecting rod, and the circle wheel is in and can be pushed up the place, operating axis end that reaches by hand arm.Electronic on/off switch action is same as the prior art, when the manual on/off switch of need, when hand arm inserts the operating axis end interface, thrust circle wheel is lived interior the propelling, make the engagement of clutch cam out-of-gear edge cam tooth, at this moment, hand arm can easily rotate to operating axis the on/off switch position, and does not relate to gear train and motor part again; When shedding hand arm, clutch cam resets under the effect of back-moving spring, with the engagement of the cam tooth of gear face, waits for the need of electronic or closing by hand next time.
The utility model is reasonable in design, and is simple in structure, operates nimblely, need not to point out and do not damage the working face of gear, avoids artificially by force closing by hand that equipment is constituted and destroys.
Description of drawings:
Accompanying drawing is the utility model structural representation
Embodiment:
With reference to accompanying drawing, a kind of vacuum load switch driving mechanism, comprise on-load switch operating axis 1, motor 2 and gear train 3 compositions, its structure is that gear 3 is set on the operating axis 1, gear 3 end faces are provided with cam tooth 31, one clutch cams 4 and axially slide on the operating axis 1, and 1 of clutch cam 4 and operating axis are provided with back-moving spring 5, clutch cam 4 is fixed with the round wheel 42 of a thrust through connecting rod 41, and circle wheel 42 is in and can be pushed up the place, operating axis 1 end that reaches by hand arm.Motor 2 power driven gear groups 3, gear 3 passes to clutch cam 4 through edge cam tooth 31, drives operating axis 1 by clutch cam 4 and rotates.Clutch cam 4 plays manual and electronic clutch action, hand-operated rocker arm inserts top and thrust circle wheel 42, by connecting rod 41 clutch cam 4 is pushed up the engagement of taking off gear face cam tooth 31, the rotation of operating axis 1 promptly can not drive cover gear 3 thereon, pulls the gear tooth bad when avoiding manual.
