Abstract
The utility model relates to an electric jigger for steamer generator. The main body of the jigger has a motor installed on a base located the external of a casing. The end of the motor connects with a shaft coupling, of which the other end connects with a retarding mechanism. The output gear of the retarding mechanism connects with an idle pulley installed on an ejection mechanism, which is installed on the casing. The idle pulley engages with the bull gear of the jigger, which is installed the controller of rotating shaft end and is connected with the motor and a sensor on the main body of the jigger via cables. The electric jigger is compact in structure, reasonable in design, reliable in operation and low in cost. Except that a steamer generating set can be started up at any moment after being turned off, the electric jigger for steamer generator can realize automatic shutdown. Moreover, the service lifetime of a steamer generator can be prolonged. And, the electric jigger is high in automation level and deceleration efficiency.
Description
Technical field
The utility model relates to the moving equipment of a kind of rotor of steam turbo generator dish, especially a kind of steam turbine generator electric barring equipment of using than the moving rotor of steam turbo generator of slow-speed of revolution dish.
Background technique
At present, along with Chinese economic development, China has also strengthened dynamics to the exploitation and the construction in power station, and therein, the application of steam turbine generator in the power station also more and more widely.Because the steam turbine generator moment of rotation is very big, thus steam turbine generator before startup, after unit needed rotor to have certain initial velocity, generator set could start.In addition, behind the generator outage, because heat does not also in time leave; make rotor and external environment have a fixed difference difference; if stationary rotor is motionless, its inner thermal stress and extraneous gravity can make rotor generation thermal bending, and more severe patient can cause the permanent deformation of rotor shaft.So before crooked numerical value was reduced to specified value, rotor of steam turbo generator needed low-speed discs to change.Yet existing rotor of steam turbo generator dish moves the general complex structure of equipment, and retardation efficiency is not high, and automaticity is low, and fault takes place frequently, and can not realize the parking of barring gear automatically.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that exists in the above-mentioned technology; a kind of compact structure, reasonable in design is provided; reliable operation, cost is low, and Turbo-generator Set can start at any time after the shutdown and can break away from the steam turbine generator electric barring equipment of shutting down automatically behind unit starting.
In order to achieve the above object, the technical solution adopted in the utility model is: the turning engine main frame is on the outside support of casing motor to be housed, the motor end connects coupling, the coupling the other end connects reducing gear, the reducing gear output gear is connected with idle pulley, idle pulley is installed in and flicks in the mechanism, flick and be installed on the casing in the mechanism, the engagement of idle pulley and jiggering gearwheel, jiggering gearwheel are installed in rotor shaft end control cabinet and link to each other with sensor on being contained in main frame by lead and the motor of turning engine main frame.
The utility model has the advantages that:
Compact structure, reasonable in design, reliable operation; cost is low, can at any time in the starting electrical machinery group, realize the autostop of steam turbine generator electric barring equipment after shutdown in Turbo-generator Set; improved the working life of steam turbine generator greatly, its automaticity and retardation efficiency height.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1-Fig. 2 as can be known, the utility model turning engine main frame is on casing 9 outside supports motor 7 to be housed, motor 7 ends connect coupling 6, coupling 6 the other ends connect reducing gear 4, reducing gear 4 output gears are connected with idle pulley 2, idle pulley 2 is installed in and flicks in the mechanism 3, flick and be installed on the casing 9 in the mechanism 3, idle pulley 2 and 1 engagement of jiggering gearwheel, jiggering gearwheel 1 are installed in rotor shaft end control cabinet 8 and link to each other with sensor on being contained in main frame by lead 10 and the motor 7 of turning engine main frame.
The utility model mainly comprises turning engine main frame and control cabinet 8; The structure of turning engine main frame is; motor 7 is installed on the casing 9 outside supports; motor 7 ends connect coupling 6; coupling 6 is connected with reducing gear 4; its reducing gear 4 is made up of turbine and worm and a pair of gear pair; reducing gear 4 is installed in the casing 9; support by rolling bearing; the output gear of reducing gear 4 and idle pulley 2 engagements; idle pulley 2 and 1 engagement of jiggering gearwheel; jiggering gearwheel 1 is installed in the rotor shaft end, and idle pulley 2 is installed in and flicks in the mechanism 3, flicks mechanism 3 and is installed on the casing 9; jiggering gearwheel 1 outside covers with case 5; play the effect of protection jiggering gearwheel 1, control unit and change-over circuit are housed in the control cabinet 8, the data that sensor is imported into are handled with the motor master control borad and are controlled.Control cabinet 8 links to each other with sensor on being contained in main frame by lead 10 and the motor 7 of turning engine main frame.
In use, starting electrical machinery 7 drives reducing gear 4 by coupling 6, reducing gear 4 drives idle pulley 2 in succession, jiggering gearwheel 1 rotates, because jiggering gearwheel 1 is installed on the generator amature, drive also corresponding beginning of generator amature and rotate, when reaching rated speed, generator control desk is received actuating signal, after the startup, flick mechanism 3 and automatically idle pulley 2 is flicked, after idle pulley 2 is thrown off, start photoelectric sensor, control cabinet 8 receives this signal by lead 10, and control motor 7 stop operating, barring gear quits work, meanwhile, generator master control plate receives signal, the beginning proper functioning.If do not receive the signal of photoelectric sensor, generator master control plate is reported to the police automatically, and control cabinet 8 control generator master control plates are reported to the police automatically and cut off main control loop, autostop.
