Bias is hinged with propulsion pawl, and energy storage camshaft is provided in energy storage axle, promotes spine of the pawl by torsional spring and energy storage camshaft
Tooth engagement is additionally provided in rack for making after the completion of switching-in spring energy storage with pawl limit cooperation is promoted, promotes pawl
The idler wheel being detached from energy storage camshaft is additionally provided with energy-storage crank arm in energy storage axle, is arranged on the output end and rack of energy-storage crank arm
The transmission of combined floodgate spring is connected.It is additionally provided with floodgate semiaxis in rack and the switching electromagnet for driving floodgate semiaxis to rotate, energy storage are convex
The closing pawl with floodgate semiaxis limit cooperation after the completion of switching-in spring energy storage is provided on wheel shaft.When switching-in spring energy storage,
Energy storage motor drives tumbler gear rotation, tumbler gear to drive transmission gear rotation, pawl is promoted to push energy storage cam axle,
Energy storage camshaft drives energy-storage crank arm to carry out energy storage to switching-in spring, after switching-in spring energy storage, pawl is promoted to encounter rolling
The pressure that torsional spring is given is overcome when wheel just can lift and be detached with energy storage camshaft automatically, so that transmission shaft is dallied, to protect machine
Structure energy storage in place in the case of, be unlikely to mechanism to draw bad.Switching-in spring energy storage in place when, closing pawl links closely combined floodgate half
Axis, switching-in spring were in dead-centre position, and when needing closing operation, switching electromagnet pushes floodgate semiaxis to turn an angle,
Closing pawl instantaneous trip, switching-in spring release energy.
The existing this form that closing operation is just completed by switching electromagnet, lacks necessary closing protective, is easy
There is the case where breaker causes to close a floodgate suddenly in separating brake due to operating personnel's operation error, such case is danger close
's.
Utility model content
The utility model in view of the above-mentioned deficiencies in the prior art, provides a kind of spring operating mechanism.
The technical solution that the utility model solves above-mentioned technical problem is as follows：
A kind of spring operating mechanism, it is characterised in that：Including drive shaft, transmission shaft, axis first, driven shaft, connecting shaft, axis
Second, drive disk, driven disc, transmission gear and driven gear；The drive disk is the sickle shaped of upper bending and passes through its center
Circular hole is fixed on the driving shaft, and the driven disc middle and upper part is equipped with slotted hole, and the transmission gear passes through transmission shaft and driven disc
Connection, but the two is not integrated, and the driven gear is fixed by transmission shaft；The downside of the drive disk by connecting shaft with from
The slotted hole of Moving plate connects, and the lower left quarter of the driven disc is fixed with driving pawl, the upper right side of the driven disc by axis second
Equipped with managing pawl by the way that axis first is fixed, the transmission gear respectively with driving pawl and manage pawl and act on, in addition, described
Transmission gear is also acted on the driven gear of lower right side.
Compared with prior art, the utility model has the beneficial effects that：The utility model is by setting up driving pawl and behaviour
The double pawls of pawl are held, transmission gear is alternately driven or keep, transmission gear one-way movement, transmission gear is made to there is gear to have tool
There is the double characteristic of ratchet；Staff in this way can ensure electric brake when false switching by the effect of pawl
Safety.
Based on the above technical solution, the utility model can also do following improvement.
Further, the upside in knee is equipped with limit shaft in the drive disk.
Advantageous effect using above-mentioned further scheme is：The movement locus and fortune of drive disk can be limited by limit shaft
Dynamic direction, guarantee is provided for subsequent alternating movement.

Specific implementation mode
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining this practicality
It is novel, it is not intended to limit the scope of the utility model.
A kind of spring operating mechanism, including drive shaft 1, transmission shaft 2, axis first 3, driven shaft 4, connecting shaft 5, axis second 6, driving
Disk 7, driven disc 8, transmission gear 9 and driven gear 10；The drive disk 7 is the sickle shaped of upper bending and the circle by its center
Hole is fixed in drive shaft 1,8 middle and upper part of the driven disc be equipped with slotted hole 14, the transmission gear 9 by transmission shaft 2 with from
Moving plate 8 connects, but the two is not integrated, and the driven gear 10 is fixed by transmission shaft 2；The downside of the drive disk 7 passes through
Connecting shaft 5 is connect with the slotted hole 14 of driven disc 8, and the lower left quarter of the driven disc 8 is fixed with driving pawl 11 by axis second 6,
The upper right side of the driven disc 8 is equipped with manages pawl 12 by the way that axis first 3 is fixed, the transmission gear 9 respectively with driving pawl
11 act on pawl 12 is managed, in addition, the transmission gear 9 is also acted on the driven gear of lower right side 10；In the drive disk 7
The upside in knee is equipped with limit shaft 13.
The operation principle of the utility model is：
Drive shaft 1 and drive disk 7 move reciprocatingly simultaneously, and motion range is limited by limit shaft 13.
When 8 clockwise movement of driven disc, clockwise movement under the action of in axis second 6 in return spring of pawl 11 is driven, and
And keep being bonded with 9 flank of tooth of transmission gear, drive driving pawl 11 to move, the tip of driving pawl 11 heads on transmission gear 9
Tooth root, band nutating gear 9 synchronize clockwise movement, and driven gear 10 rotates counterclockwise；When transmission gear 9 rotates, it will manage
Pawl 12 jacks up, and manages pawl 12 under the action of return spring with the flank of tooth for being bonded transmission gear 9 as driving pawl 11 always；
When driven disc 8 rotates counterclockwise, manages the limit moving gear 9 of pawl 12 and remain stationary as, when driven disc 8 rotates clockwise again,
Transmission gear 9 follows driven disc 8 to rotate, and such drive disk 7 and driven disc 8 move repeatedly, and transmission gear 9 is made to realize list clockwise
To rotation.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
