The neutral gear part is arranged on the ratchet wheel of the intelligent universal type motor-operating mechanism of the breaker disclosed by the invention, the accumulation of energy for the breaker is ended, and the support is inserted into the neutral gear part when the ratchet wheel is rotated to the set angle, so that the support is released from the ratchet wheel without providing a special component for pushing the support away; the intelligent universal type motor-operating mechanism of the breaker not only has a simple structure, convenience and rapidness in installation and saved cost, but also has good performance and capability of ensuring one-way operation of the main shaft of the breaker.
Description
Technical field
The present invention relates to a kind of circuit breaker operation mechanism, relate in particular to a kind of intelligent universal circuit breaker electric motor operating mechanism.
Background technology
Traditional circuit breaker operation mechanism generally comprises the ratchet that is installed on the main shaft, cooperate ratchet to be provided with support, described support is connected with the eccentric shaft of decelerator by transmission mechanism, driving ratchet by the reciprocating motion of supporting rotates, ratchet drives main shaft again and moves in a circle, realization is to the energy storage of circuit breaker, after ratchet turns to set angle, the energy storage of circuit breaker finishes, just need controlling organization, make to support and break away from ratchet, damage circuit breaker and other operating mechanisms to avoid motor under inertia, to drive main axis rotation, at present, generally adopt control board is set on the upper surface of ratchet, utilize control board to back down to be installed on the top board in the support, thereby realize supporting and the disengagement of ratchet.Obviously, there is complex structure in this mode of backing down support, installs loaded down with trivial detailsly, and cost is higher, the shortcoming that performance reliability is low.
Summary of the invention
The object of the present invention is to provide a kind of intelligent universal circuit breaker electric motor operating mechanism, it has simple in structure, saves cost, well behaved characteristics.
The objective of the invention is to be achieved through the following technical solutions:
A kind of intelligent universal circuit breaker electric motor operating mechanism, it comprises bent plate and the ratchet that is installed on the main shaft, corresponding ratchet is provided with support close-fitting with it, and described bloster hinge is connected in an end of rocking arm, the other end hinge connecting plate of described rocking arm, described connecting plate connects power set, wherein, described ratchet is provided with the neutral portion that is lower than the ratchet height, and described neutral portion is the curved surface smooth structure of no profile of tooth, after ratchet turns to set angle, support the neutral portion that embeds.
Especially, described power set are for being installed in interconnective motor and decelerator on the bent plate, and eccentric shaft on the described decelerator and connecting plate are hinged.
Especially, described bent plate is provided with positioning supports, and described positioning supports is embedding between the ratchet of ratchet under the effect of spring.
Beneficial effect of the present invention is, the ratchet of described intelligent universal circuit breaker electric motor operating mechanism is provided with neutral portion, after ratchet turns to set angle, the circuit breaker energy storage finishes, and supports the neutral portion that embeds, thereby realizes the disengagement of support and ratchet, need not the special parts of pushing support open that are provided with, not only simple in structure, it is convenient to install, and saves cost; And functional, can guarantee the unidirectional running of circuit breaker main shaft.

Embodiment
Please refer to Figure 1 and Figure 2, Fig. 1 is the structural representation of intelligent universal circuit breaker electric motor operating mechanism of the present invention; Fig. 2 is the structural representation of the ratchet of intelligent universal circuit breaker electric motor operating mechanism of the present invention.
In present embodiment, described intelligent universal circuit breaker electric motor operating mechanism, it comprises bent plate 3, described bent plate 3 is installed on main shaft 5 and the circuit breaker entablature 10, on the described main shaft 5 ratchet 4 is installed also, and corresponding ratchet 4 is provided with support 7 close-fitting with it, described ratchet 4 is provided with the neutral portion 9 that is lower than the ratchet height, described neutral portion 9 is the curved surface smooth structure of no profile of tooth, after ratchet 4 turns to set angle, supports 7 and embeds neutral portions 9.
Described support 7 is hinged in an end of rocking arm 8, the other end hinge connecting plate (not illustrating among the figure) of described rocking arm 8, described connecting plate is mounted on the bent plate 3 and interconnective motor 1 and decelerator (not illustrating among the figure), described decelerator eccentric shaft 2 is hinged with connecting plate, and described bent plate 3 is provided with positioning supports 6, described positioning supports 6 is embedding under the effect of spring between the ratchet of ratchet 4, to avoid ratchet 4 in the instantaneous reversing of supporting 7 disengaging ratchets 4.
During work, motor 1 drives decelerator eccentric shaft 2 and rotates, decelerator eccentric shaft 2 drives rocking arm 8 by connecting plate and moves reciprocatingly; the support 7 promotion ratchets 4 on the rocking arm 8 rotate; the main shaft 5 that ratchet 4 drives on the circuit breaker again moves in a circle; after the angle that turns to ratchet 4 settings; the circuit breaker energy storage finishes; at this moment; the support 7 on the rocking arm 8 just in time is in the neutral portion 9 on the ratchet 4; avoid electronic 1 to drive main shaft 5 rotations and damage circuit breaker and other operating mechanisms under inertia, prolonged the useful life of circuit breaker and electric motor operating mechanism.
The neutral portion 9 that above-mentioned intelligent universal circuit breaker electric motor operating mechanism utilizes ratchet 4 self to be provided with, realize supporting 7 with the separating of ratchet 4, need not the special parts of pushing support open that are provided with, not only simple in structure, it is convenient to install, the saving cost; And functional, can guarantee the unidirectional running of circuit breaker main shaft.
