Embodiment
Embodiments of the present invention is further illustrated below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with Fig. 2,3,4,5, shown in 6, a kind of electric spring operation machine, comprise two blocks of side plates 1, be provided with switching-on mechanism between described two blocks of side plates 1 and divide gate controlling mechanism, gate controlling mechanism comprised separating brake sincere sub 23 in described minute, separating brake secondary sincere sub 24, separating brake thread off sincere sub 25 and separating brake magnet 26 (dividing the fit structure of gate controlling mechanism is common practise, do not give unnecessary details at this), described switching-on mechanism comprises energy storage motor 2, switching-in spring 3, making electromagnet 4, energy storage sprocket wheel 5, drive plate 6 and limit shaft 7, also be provided with gusset plate 8, be formed for the cavity 9 of ccontaining brake separating mechanism between described gusset plate 8 and one of them side plate 1, described brake separating mechanism comprises driving shaft 10, separating brake connecting lever 11 and tripping spring 12, drive plate 6 on described driving shaft 10 and the switching-on mechanism is connected, specifically, described driving shaft 10 and drive plate 6 are connected by spline.Described separating brake connecting lever 11 is sheathed on the driving shaft 10 and with driving shaft 10 and links, and described separating brake connecting lever 11 is connected with tripping spring 12.The invention has the beneficial effects as follows, set up brake separating mechanism, make the present invention have the divide-shut brake function simultaneously, the divide-shut brake debugging is simple, has guaranteed the performance of product, with other power consumption equipment assembling where applicables, easy to assembly, reliable in mechanical performance can provide powerful operating work, 13000 joules be can reach, high pressure, extra high voltage circuit breaker and fully closed combined electric unit can be used for.Arranging of gusset plate can be played the protection of brake separating mechanism and the double effects that the staff is protected; make that security of products can be better; and the present invention is simple in structure, dependable performance, easy to assembly, and is even also can be suitable for the high voltage power distributing cabinet with the separating brake function not, adaptive wider.
Described separating brake connecting lever 11 is connected with tripping spring 12 by chain 13.One end of described tripping spring 12 is provided with baffle plate 14, and the other end is provided with pressing plate 15, and described chain 13 passes tripping spring 12 and links to each other with pressing plate 15.Be provided with installation shaft 16 between described gusset plate 8 and the side plate 1, described installation shaft 16 is provided with the roller 17 that turns to for chain 13.Such structure can make tripping spring fast, compress reliably or flick.
Described separating brake connecting lever 11 is triangle, and two angles of separating brake connecting lever 11 are connected with driving shaft 10, tripping spring 12 respectively, is connected with the operator link 18 that links to each other with killer switch on another angle of separating brake connecting lever 11.Separating brake connecting lever 11 is generally triangle or class triangle, can certainly be other shapes such as circle, but circular occupation space is bigger, so triangle is optimal way.Such structure has effectively been utilized the space in the cavity, can make that the space between the biside plate becomes big simultaneously, makes product easy to assembly.
Be arranged with self-aligning bearing 19 on the described driving shaft 10, described self-aligning bearing 19 is located on the gusset plate 8.Self-aligning bearing the swing that has limited driveshaft end is set, make driving shaft stressed stressed to be improved as fixed middle part, two ends stressed by cantilever beam, make the intensity of driving shaft improve greatly.
Described limit shaft 7 combines by rubber sleeve is alternate with steel bushing.The existing good shock-absorbing capacity of such structure has the limit function of divide-shut brake again
Thermal energy storage process: referring to accompanying drawing 1, shown in Figure 2, after energy storage motor 2 is connected power supply, slow down by gear, sprocket wheel, energy storage sprocket wheel 5 clockwise rotates, link plate 20 drives chain compression switching-in spring 3, sincere sub 21 the time near closing a floodgate when the roller on the energy storage sprocket wheel 5, the power supply of energy storage motor 2 is cut off, and energy storage is finished.Certainly the present invention can receive that also transmitting gear, sprocket wheel carry out energy storage.
Making process: referring to Fig. 1, Fig. 2, when making electromagnet 4 is subjected to electronic work, cause sincere sub 21 dropouts of closing a floodgate, switching-in spring 3 releases energy, and cam 22 rotates, and drives drive plate 6 and turns to closing position, and separating brake sincere sub 23 is fastened.Referring to Fig. 3, Fig. 4, because driving shaft 10 is connected with drive plate 6, specifically, driving shaft 10 and drive plate 6 are connected by spline, separating brake connecting lever 11 counter-clockwise swings when making drive plate 6 rotations, make breaker body close a floodgate by operator link 18, in the time of the breaker body feed motion, separating brake connecting lever 11 drives tripping spring 12 compressions and energy storage by chain 13.Close a floodgate among the present invention and chain that separating brake adopts be the same, still the on/off switch of consideration need the energy difference, so tripping spring and switching-in spring coefficient of elasticity different.
The separating brake process: referring to Fig. 1, Fig. 2, when separating brake magnet 26 is subjected to electronic work, separating brake secondary sincere sub 24 and separating brake are threaded off and sincere sub 25 are threaded off, referring to Fig. 5, Fig. 6, tripping spring 12 releases energy, and clockwise rotates by separating brake connecting lever 11, drive operator link 18 and move downward breaker open operation.Certainly, the present invention also can drive breaker open operation by driving the operation connecting lever of circuit breaker, is manual control operation part of the present invention.
Every technical staff's notice: though the present invention describes according to above-mentioned embodiment, invention thought of the present invention is not limited in this invention, and the repacking of any utilization inventive concept all will be included in this patent scope of patent protection.
