Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1. hydrogenerator frame, 2. hydraulic generator rotor, 3. shaft coupling, 4. jiggering workbench, 5. motor, 6. reductor, 7. little gear, 8. gear wheel, 9. driving shaft, 10 shifting blocks, 11. passive plates, A. cavity.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is further elaborated.
A kind of hydrogenerator electric barring, its structure is as it is shown in figure 1, include jiggering workbench 4, driving mechanism, gear wheel and adapter；Jiggering workbench 4 is fixedly installed in hydrogenerator frame 1；Driving mechanism is arranged on above jiggering workbench, is used for driving gear wheel to rotate；Gear wheel is arranged on below jiggering workbench by the fixing axle of gear, and it is parallel to jiggering workbench, the shaft coupling 3 that gear wheel turns top by adapter with hydrogenerator is connected, and for driving hydraulic generator rotor action under the effect of driving mechanism, completes jiggering operation.
Adapter includes being arranged on the bottom face of gear wheel driving shaft 9 and be fixedly installed on the passive plate 11 on shaft coupling top, driving shaft 9 bottom is plugged in passive plate 11；It is provided with cavity A, for installing the accessory of jiggering operation between passive plate 11 and gear wheel 8.For ensureing the stress balance of passive plate, driving shaft may be configured as two or more, and these driving shafts are evenly arranged on the circumference of gear wheel bottom face.
In this utility model, passive plate can adopt flat position, through hole or shifting block form with coordinating of driving shaft, no matter adopting any of the above-described kind of structure, be matched in clearance with coordinating of driven axle, namely flat position, through hole or shifting block are provided with the allowance space for driven axle return.
Driving mechanism includes motor 5, reductor 6 and little gear 7, and little gear 7 is positioned at below jiggering workbench and is meshed with gear wheel 8.Driving mechanism in this utility model can arrange more than two sets or two sets, and the even circumferential of these driving mechanism correspondence gear wheels is arranged on jiggering workbench.
The driving mechanism control chamber control action by being independently arranged, control chamber is provided with step switch group and display lamp group, step switch group includes power main switch, control on and off switch, main shaft normal inching turning switch, main shaft rotates forward coupled switch, main shaft reverse inching turning switchs and main shaft reversion coupled switch, and display lamp group includes power supply indicator, main shaft rotating forward display lamp and main shaft reversion display lamp.
