Description
Technical Field
The utility model relates to a spring operating device, concretely relates to double spring operating device for vacuum circuit breaker.
Background
The spring operating mechanism is an important component of the vacuum circuit breaker and is used for controlling the on-off of a circuit. The spring operating mechanism is an operating mechanism which takes a spring as a power element to carry out switching-off and switching-on operations on the vacuum circuit breaker, can well meet the power matching characteristic required by the vacuum circuit breaker, and has reliable working performance. The existing spring operating mechanism comprises a machine frame, an energy storage transmission assembly arranged on the machine frame and an output transmission assembly arranged on the machine frame, however, the structural design of the existing spring operating mechanism is unreasonable, the energy storage transmission assembly of the existing spring operating mechanism adopts a single spring structural design, the fatigue resistance of a single spring cannot meet the use requirement of a user, and therefore the spring operating mechanism has the defect of short service life. When the brake is switched off, the limiting plate, the backing plate and the baffle on the output transmission assembly of the spring operating mechanism are repeatedly impacted to cause the deformation of the backing plate and the baffle, so that the service life of the spring operating mechanism is greatly shortened, and the spring operating mechanism has the defects of complex structure, unreliable performance and short service life.
Disclosure of Invention
An object of the utility model is to overcome prior art's defect, provide a simple structure, stable performance are reliable, long service life's two spring operating device.
For realizing above-mentioned purpose, the utility model discloses a double spring operating device, including framework, the energy storage drive assembly who sets up on the framework, with energy storage drive assembly matched with mainspring, the output drive assembly who sets up on the framework, output drive assembly including rotate set up on the framework output shaft, with output shaft linkage complex output turning arm, correspond output turning arm department set up the limiting plate on the framework, the activity sets up on the limiting plate and with output turning arm linkage complex pull rod, set up the spring between pull rod and limiting plate, one side of limiting plate on correspond output turning arm department and be provided with the blotter, be provided with on this blotter with output turning arm matched with backing plate.
The beneficial effect of above-mentioned structure is: be provided with respectively on the limiting plate with output turning arm matched with blotter, backing plate, the backing plate adopts 45 steel sheets and carries out thermal treatment process and make, and the blotter adopts polyurethane cowhells board to make, and withstand voltage takes precautions against earthquakes, shock-resistant, wearability are better to can avoid the limiting plate to warp because of receiving the impact of output turning arm, be favorable to prolonging this spring operating device's life.
Particularly, the limiting plate is in a [ -shape, three insertion parts are respectively arranged on one side of the limiting plate, the three insertion parts are respectively inserted into the insertion holes of the machine frame, and the three insertion parts are respectively welded in the insertion holes. The limiting plate is welded on the framework in a limiting mode in three directions, the limiting plate and the framework can be welded more firmly, and the supporting effect of the limiting plate is better.
Particularly, the main spring comprises a small spring and a large spring sleeved outside the small spring, one end of the small spring and one end of the large spring are respectively connected to a pulling plate of the machine frame, and the other end of the small spring and the other end of the large spring are respectively connected to an energy storage crank arm of the energy storage shaft. The main spring adopts a double-spring structural design, so that the fatigue resistance of the main spring can be enhanced, and the service life of the spring operating mechanism can be prolonged.
