Abstract
The utility model belongs to a spring-operation device for a high voltage switch, composed of side plates, shafts, cams, gears, springs, a power unit, etc. The utility model is characterized in that two side plates are connected with main shafts, output shafts, power storing shafts and spring brackets in parallel. The power storing shafts are fixedly sheathed with gears. The power unit drives the gears to engage with one-way gears. The main shafts are sheathed with one-way gears and cams. One end of each main shaft is fixed with a crank rod. Both ends of power storing springs are respectively connected with crank rods of the spring support brackets. The output shafts are fixed with crank arms. The crank arms are provided with rollers which are contacted with the cams.
Description
The utility model belongs to used for high-voltage switch spring powder operation device.
Original used for high-voltage switch spring powder operation device is made up of energy-storage system, combined floodgate tripping system and separating brake tripping system; Give spring energy-storage by manpower or motor by energy-storage system earlier during operation; Energy storage is finished rear spring by the locking of combined floodgate tripping system, is in the dispensing state of waiting for; The combined floodgate tripping system is triped, and the energy-stored spring dispensing provides energy for switch closes a floodgate, and switch is closed merge into the tripping spring energy storage, and this moment, the separating brake tripping system was in the snap close state; The separating brake tripping system is triped, and switch is separating brake under the tripping spring effect.Switch is finished the circulation of once closing the branch operation under the spring powder operation device drives like this.Therefore this spring actuating size is bigger, complex structure, and its reliability is lower, the tool statistics, the operation troubles of high-voltage switch gear more than 70% caused by powder operation device.
The purpose of this utility model provides a kind of device, and it omits the combined floodgate tripping system, forms the spring powder operation device by energy-storage system and separating brake tripping system, realizes miniaturization.Oversimplify, improved reliability.
Design of the present utility model is: design the spring powder operation device that a kind of side plate, axle, cam, gear, spring, actuating unit etc. are formed, it is characterized by: parallel main shaft, output shaft, the energy storage axle of being connected with on biside plate, and spring support, fixed cover is connected to gear and actuating unit on the energy storage axle, and gear is meshed with ratchet; Be socketed with ratchet and cam on the main shaft, main shaft one end is fixed with the cripple; The energy-stored spring two ends are connected on spring support and the cripple; Be fixed with connecting lever on the output shaft, have roller to contact on the connecting lever with cam.
The utility model fast actuating unit can be that the driven by motor reduction box is formed, also can be manual axle.
Advantage of the present utility model is as follows:
Because the spring powder operation device of the utility model design is directly by the gear drive ratchet by actuating unit, and drive main shaft 2 is the energy-stored spring energy storage, the energy-stored spring energy storage finishes and turns over the dead point delivered energy of overturning automatically and finish the energy storage and the output function of spring powder operation device, and this structure has been saved original multistage transmission mechanism combined floodgate tripping system.Simple in structure, production cost is low, and has reduced failure rate, has improved reliability of products.
Below in conjunction with accompanying drawing the utility model is described further.
Accompanying drawing 1 is the utility model example structure schematic diagram.
Accompanying drawing 2 is an accompanying drawing 1A-A cut-away view.
Among the figure: 1. side plate, 2. main shaft, 3. cam, 4. ratchet, 5. output shaft, 6. actuating unit, 7. the energy storage axle 8. cogs, 9. energy-stored spring, 10. spring support, 11. cripples, 12. rollers, 13. connecting levers.
Secured in parallel has energy storage axle 7, main shaft 2, output shaft 5 between biside plate 1.When using driven by motor, actuating unit 6 cogs by drive and 8 directly drives ratchet 4 interlock main shafts 2, the energy-stored spring energy storage is finished turn over the dead point delivered energy of overturning automatically to drive output shafts 5 by cam 3, finishes the energy storage and the output of spring powder operation device.When manual energy storage, the direct driving main shaft 2 of manpower is rotated, and this moment, ratchet 4 disengaging transmissions were to reduce the resistance on the main shaft.
Claims (2)
1. the spring powder operation device formed such as a side plate, axle, cam, gear, spring, actuating unit, it is characterized by: parallel main shaft, output shaft, energy storage axle, the spring support of being connected with on biside plate, fixed cover is connected to gear and actuating unit on the energy storage axle, and gear is meshed with ratchet; Be socketed with ratchet and cam on the main shaft, main shaft one end is fixed with the cripple; The energy-stored spring two ends are connected on spring support and the cripple; Be fixed with connecting lever on the output shaft, have roller to contact on the connecting lever with cam.
2. spring powder operation device according to claim 1, its feature also is: actuating unit can be that motor interlock reduction box is formed, and also can be manually, directly driving main shaft.
