Fig. 1 is a kind of structural representation of the present invention;
Fig. 2 is the cutaway view of Fig. 1 along A-A line;
Fig. 3 is a kind of perspective view of mechanism body in Fig. 1.
In figure, sequence number illustrates: 1 installing rack, 2 bearing pedestals, 3 hollow shafts, 4 straight plate torsion springs, 5 axle sleeves, 6 frameworks, 7 operating axis, 8 cams, 9 ratchets, 10 supports, 11 separating brake ratchets, 12 splice grafting ground ratchets, 13 points of ground connection ratchets, 14 combined floodgate ratchets, 15 springs.
Embodiment
Concrete structure of the present invention is described in detail according to Fig. 1 ~ 3.The small modular operating mechanism of this three station isolation grounding switch comprises for parts such as the installing rack 1 of fixing isolating switch pole, the rotating shaft utilizing bearing pedestal 2 and support 10 assembling be fixed on installing rack 1 and mechanism body.Its shaft is the hollow shaft 3 that inner chamber is provided with straight plate torsion spring 4.Periphery is that one end of hexagonal hollow shaft 3 and straight plate torsion spring 4 utilizes same axle sleeve 5 to be assembled on bearing pedestal 2.The cross section of axle sleeve 5 adopts inner circumferential to be hexagon, and periphery is circular sleeve, together can rotate with hollow shaft 3 and the sliding bearing in bearing pedestal 2.
Mechanism body comprises clamping plate type framework 6, be assembled in the ratchet 9 in framework 6, the multiple ratchets be meshed with ratchet 9 periphery, as separating brake ratchet 11, splice grafting ground ratchet 12, point ground connection ratchet 13 and combined floodgate ratchet 14, cam 8, the part such as operating axis 7 grade that drive cam shaft is rotated.Mechanism body is fixed on the support 10 of installing rack 1 other end.The other end of hollow shaft 3 is coaxially fixedly connected with ratchet 9, rotates together.The axle center of cam 8 that operating axis 7 drives and the axle center of ratchet 9 are positioned on same axis.Operating axis 7 driving cam 8 rotates, can drive ratchet 11 ~ 14 on diverse location respectively with the clutch of ratchet 9, make ratchet 9 and hollow shaft 3 rotate simultaneously or stop simultaneously.The other end of straight plate torsion spring 4 is fixedly connected with camshaft, and rotates with cam 8 and complete the storage of energy, also can complete the release of energy with the rotation of ratchet 9 and hollow shaft 3.When the axle of operating axis 7 driving cam 8 rotates, and ratchet 9 by ratchet 11 ~ 14 withstand no longer rotate time, then straight plate torsion spring 4 is now by energy storage.When backing down in ratchet 11 ~ 14 when the boss of cam 8 periphery rotated, straight plate torsion spring 4 just releases energy, thus driving pawl 9 and hollow shaft 3 rotate, until when ratchet 9 is withstood by next ratchet, stop operating.
During separating brake, use the counterclockwise actuating operating axis 7 of operating grip, operating axis 7 driving cam 8 and straight plate torsion spring 4 rotate, because one end of straight plate torsion spring 4 and hollow shaft 3 is fixed on axle sleeve 5, the other end and the ratchet 9 of hollow shaft 3 are fixed, the stop of separating brake ratchet 11, makes ratchet 9 and hollow shaft 3 not rotate, so straight plate torsion spring 4 is by energy storage.When cam 8 backs down separating brake ratchet 11, ratchet 9 loses stop, and the energy of spring store is released, and energy drives ratchet 9 and the hollow shaft 3 of abrupt release rotate, and realize the quick acting switching-off of operating mechanism.When splice grafting ground ratchet 12 withstands ratchet 9, hollow shaft 3 stops operating.Realize separating brake ratchet 11 by spring 15 to reset, now realize the isolated operation of three station isolation grounding switchs.
During splice grafting ground, use the counterclockwise actuating operating axis 7 of operating grip, operating axis 7 driving cam 8 and straight plate torsion spring 4 rotate, and due to the stop of splice grafting ground ratchet 12, ratchet 9 and hollow shaft 3 can not rotate, so straight plate torsion spring 4 is by energy storage.When cam 8 backs down splice grafting ground ratchet 12, ratchet 9 loses stop, and the energy of spring store is released, and the energy of abrupt release promotes ratchet 9 and hollow shaft 3 rotates.When combined floodgate ratchet 14 withstands ratchet 9, hollow shaft 3 stops operating.Realize splice grafting ground ratchet 12 by spring 15 to reset, now realize the ground connection operation of three station isolation grounding switchs.
When dividing ground connection, use the clockwise actuating operating axis 7 of operating grip, operating axis 7 driving cam 8 and straight plate torsion spring 4 rotate, and due to the stop of combined floodgate ratchet 14, ratchet 9 and hollow shaft 3 can not rotate, so straight plate torsion spring 4 is by energy storage.When cam 8 backs down combined floodgate ratchet 14, ratchet 9 loses stop, and the energy of spring store is released, and the energy of abrupt release promotes ratchet 9 and hollow shaft 3 rotates, and realizes the rapid grounding of operating mechanism.When a point ground connection ratchet 13 withstands ratchet 9, hollow shaft 3 stops operating.Realize combined floodgate ratchet 14 by spring 15 to reset, now realize point ground connection operation of three station isolation grounding switchs.
During combined floodgate, use the clockwise actuating operating axis 7 of operating grip, operating axis 7 driving cam 8 and straight plate torsion spring 4 rotate, and due to the stop of point ground connection ratchet 13, ratchet 9 and hollow shaft 3 can not rotate, so straight plate torsion spring 4 is by energy storage.When cam 8 backs down point ground connection ratchet 13, ratchet 9 loses stop, and the energy of spring store is released, and the energy of abrupt release promotes ratchet 9 and hollow shaft 3 rotates, and realizes the rapid grounding of operating mechanism.When separating brake ratchet 11 withstands ratchet 9, hollow shaft 3 stops operating.Realize a point ground connection ratchet 13 by spring 15 to reset, now realize the closing operation of three station isolation grounding switchs.
