Embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention is further illustrated:
By Fig. 1 in conjunction with Fig. 2, 3, shown in 4, a kind of frame circuit breaker energy storing drive device, comprise the first ratchet 4 being arranged on circuit breaker power transmission shaft 6, be arranged on circuit breaker side plate 1 first pallet 2 and the operating grip 3 suitable with the first ratchet 4, described power transmission shaft 6 is provided with the tooth papillae assembly 7 that is connected the first gear 5 and is rotatably assorted with power transmission shaft 6 with circuit breaker power transmission shaft 6, tooth papillae assembly 7 its installing holes are circular hole, tooth papillae assembly 7 can rotate around power transmission shaft 360 degree, between described operating grip 3 and tooth papillae assembly 7, be provided with arrangement of clutch 9, described tooth papillae assembly 7 comprises the second gear 71 being connected with gear assembly 8 and the second ratchet 72 matching with the second pallet 93 on arrangement of clutch 9, described side plate 1 is provided with installation shaft 10, described gear assembly 8 is located in installation shaft, described gear assembly 8 and the first gear 5 are connected.The invention has the beneficial effects as follows, increased the first gear, tooth papillae assembly, gear assembly and arrangement of clutch, when not changing power transmission shaft rotation direction, can be according to the difference of gearratio while making breaker energy storage, workman's operating physical force while reducing energy storage, minimizing workman's labour intensity.And the present invention also has simple and reasonablely, operation is advantage easily merrily and lightheartedly.
Described gear assembly 8 comprises the 3rd gear 81 being meshed with the second gear 71 and the 4th gear 82 being meshed with the first gear 5, described the 3rd gear 81 and the 4th gear 82 are connected, the second described gear 71 and the gearratio of the 3rd gear 81 are 1:1, and the gearratio of the 4th gear 82 and the first gear 5 is 1:2 or 1:3.Certainly, can regulate the gearratio of the second gear 71 and the 3rd gear 81, and the gearratio that regulates the 4th gear 82 and the first gear 5, make this product to make workman laborsaving according to the gearratio of arbitrary proportion, but such gearratio setting can increase difficulty of processing and the production cost of product.Due to the reserved limited space of its operating mechanism of frame-type circuit breaker, therefore the transmission specific energy that the 4th gear 82 and the first gear 5 arrange 1:2 is economized half power for workman, meet workman's production, operation requirements, make again workman's operation be unlikely to undue loaded down with trivial details, be optimal way of the present invention simultaneously.The second described gear 71 is connected by rivet 73 with the second ratchet 72.Such structure makes the production and processing of tooth papillae assembly convenient, dependable performance.
Described arrangement of clutch 9 comprises the cam 91 that is connected with power transmission shaft 6, be located at the dividing plate 92 in operating grip 3 and be located on dividing plate 92 and with tooth papillae assembly 7 on suitable the second pallet 93 of the second ratchet 72, the second described pallet 93 has the primary importance of blocking tooth papillae assembly 7 and the second place that is made operating grip 3 idle running by cam 91 jack-up.Such structure can make power transmission shaft reliable movement while making operating grip work, when energy storage completes, by cam jack-up the second pallet, makes operating grip idle running, plays the effect of clutch.
Described power transmission shaft 6 is provided with V-type groove 61, on the first described ratchet, the first gear, cam, is equipped with the fixture block suitable with V-type groove, and the first ratchet, the first gear, cam can be connected with power transmission shaft.
The course of work, workman's rotating operation handle 3, operating grip is by rotate counterclockwise (during the energy storage) of dividing plate 92, and the second pallet 93 on dividing plate 92 drives tooth papillae assembly 7 to rotate, and the second pallet 93 is contained on dividing plate 92, and resets by back-moving spring 94; Tooth papillae assembly 7 driven gear assemblies 8 rotate, and in energy storing drive device, installation shaft 10 is fixed on side plate 1, and gear assembly 8 is arranged in installation shaft 10; Gear in gear assembly 8 the 4th gear driven the first gear 5 rotates, and the first described gear 5 drives V-type power transmission shaft 6 to rotate, and V-type power transmission shaft 6 drives structural member motion in the first ratchet 4, cam 91 and stored energy mechanism.When dividing plate 92 rotate counterclockwise certain angle time, the first pallet 2 is under the effect of spring, embed in the groove of the first ratchet 4, stop 6 counter motions of V-type power transmission shaft, continued operation 13 times or 14 times, can complete whole thermal energy storage process, now cam 91 carrys out the second pallet 93 jack-up, makes dividing plate 92 after completing stored energy operation, while being rotated further, realize " idle running " function of operating grip, cam 91 coordinates with the second pallet 93 effect of having played clutch.
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.
