Embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention is further illustrated:
By Fig. 1 composition graphs 2, 3, 4, 5, shown in 6, a kind of electric spring operation machine, comprise two blocks of side plates 1, switching-on mechanism and point gate controlling mechanism is provided with between two blocks of described side plates 1, a described point gate controlling mechanism comprises separating brake sincere sub 23, separating brake secondary sincere sub 24, (fit structure of point gate controlling mechanism is common practise for separating brake dropout sincere sub 25 and separating brake magnet 26, therefore not to repeat here), 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, the cavity 9 being used for accommodating brake separating mechanism is formed 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, described driving shaft 10 is connected with the drive plate 6 on switching-on mechanism, specifically, described driving shaft 10 is connected by spline with drive plate 6.Described separating brake connecting lever 11 to be sheathed on driving shaft 10 and to be connected with driving shaft 10, 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 divide-shut brake function, divide-shut brake debugging is simple, ensure that the performance of product simultaneously, where applicable is assembled with other power consumption equipments, easy to assembly, reliable in mechanical performance, can provide powerful operating work, 13000 joules can be reached, can be used for high pressure, extra high voltage circuit breaker and fully closed combined electric unit.Arranging of gusset plate can be played the protection of brake separating mechanism and the double effects to staff's protection; make the security performance of product better; and structure of the present invention is simple, dependable performance, easy to assembly, even if also can be suitable for the high voltage power distributing cabinet not with separating brake function, 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 is connected with pressing plate 15 through tripping spring 12.Be provided with installation shaft 16 between described gusset plate 8 and side plate 1, described installation shaft 16 is provided with the roller 17 turned to for chain 13.Such structure can make tripping spring compress fast, 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, another angle of separating brake connecting lever 11 are connected with the operator link 18 be connected with killer switch.Separating brake connecting lever 11 is generally triangle or class triangle, can certainly be other shapes as circle, but the space that circle takies is larger, so triangle is optimal way.Such structure effectively make use of the space in cavity, the space between biside plate can be made simultaneously to become large, make the easy to assembly of product.
Described driving shaft 10 is arranged with self-aligning bearing 19, and described self-aligning bearing 19 is located on gusset plate 8.The setting of self-aligning bearing limits the swing of driveshaft end, make driving shaft stressed by cantilever beam, stressed to be improved as fixed middle part, two ends stressed, the intensity of driving shaft is improved greatly.
Described limit shaft 7 combines by rubber sleeve is alternate with steel bushing.The existing good shock-absorbing capacity of such structure, has again the limit function of divide-shut brake
Thermal energy storage process: shown in accompanying drawing 1, Fig. 2, after energy storage motor 2 switches on power, by gear, chain sprocket decelerating, energy storage sprocket wheel 5 rotates clockwise, link plate 20 drives chain to compress switching-in spring 3, when the roller on energy storage sprocket wheel 5 is near closing pawl 21, the power supply of energy storage motor 2 is cut off, and energy storage completes.Certain the present invention also can receive transmitting gear, sprocket wheel carries out energy storage.
Making process: referring to Fig. 1, Fig. 2, when the powered action of making electromagnet 4, cause closing pawl 21 to be threaded off, switching-in spring 3 releases energy, and cam 22 rotates, and drive drive plate 6 to turn to closing position, separating brake sincere sub 23 is fastened.Referring to Fig. 3, Fig. 4, because driving shaft 10 and drive plate 6 are connected, specifically, driving shaft 10 is connected by spline with drive plate 6, separating brake connecting lever 11 counter-clockwise swing when drive plate 6 is rotated, by operator link 18, breaker body is closed a floodgate, while breaker body feed motion, separating brake connecting lever 11 drives tripping spring 12 to compress and energy storage by chain 13.To close a floodgate in the present invention and chain that separating brake adopts is the same, but the energy difference of the on/off switch needs considered, so tripping spring and switching-in spring coefficient of elasticity different.
Separating brake process: referring to Fig. 1, Fig. 2, when the powered action of separating brake magnet 26, separating brake secondary sincere sub 24 and separating brake dropout sincere sub 25 are threaded off, referring to Fig. 5, Fig. 6, tripping spring 12 releases energy, and is rotated clockwise by separating brake connecting lever 11, operator link 18 is driven to move downward, breaker open operation.Certainly, the present invention also can by driving the operation connecting lever of circuit breaker, and driving breaker open operation, is Non-follow control operation part of the present invention.
Every technical staff's notice: although 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 include in this patent scope of patent protection.
