Description
Technical field
The utility model relates to the moving equipment of a kind of hydraulic generator rotor dish, the especially a kind of machinery check and repair of power plant and hydraulic generator electric barring equipment of installation process of being used for.
Background technology
At present, along with Chinese economic development, China has also strengthened dynamics to the exploitation and the construction in power station, and therefore, the application of hydraulic generator in the power station also more and more widely.Yet, in the process that the hydraulic generator unit is installed, the quality of axis, the installation of whole shaft system of unit cooperates, and is directly connected to the safe and stable operation of unit.The adjustment of axle system need be rotated a week to rotor by manpower usually, generally be to finish by thrust bearing, so that determine the practical center of unit and the deviation between the theoretical center, and adjust according to measurement data, can not be exaggerated the usefulness that exceeds standard and influence unit if do not adjust its deviation by the axis prolongation, so common needs rotates repeatedly, find best center to positive status as far as possible, and repeatedly initiatively mainly drive the rotation of hydraulic generator rotor by coiling equipment and manpower jiggering.Now, the method that turning hydrogenerator set for alignment adopts at present is divided into two big classes, and a class is an electric turning, and another kind of is mechanical jiggering.Electric turning is to utilize to feed the electromagnetic torque that direct current produced in generator unit stator, the rotor coil, drags the rotor rotation of hydraulic generator, and this mode is had relatively high expectations to equipment, and cost is higher.The machinery jiggering is divided into manpower jiggering, bridge machine travel jiggering, motor machine jiggering etc. again.The manpower jiggering is that manpower promotion hydraulic generator rotor carries out jiggering, and this jiggering mode expends people's muscle power, and labour intensity is big; Bridge machine travel jiggering is the bridge machine that utilizes in the factory, and through the assembly pulley commutation, with the method for rope traction unit rotor rotation, its complex operation, jiggering efficient is not high, and the jiggering precision is low, and rest point is not accurate enough; The motor machine jiggering is to utilize motor-driven, and through gear, coupling body etc. are realized jiggering, turning gear is born by generator amature, increased the weight of the load of generator amature, in addition, motor is along with mechanism's integral body is rotated by rotor driven in the existing turning gear, lead easily twines, cause the potential safety hazard of equipment easily, and the most complex structure of existing motor machine turning gear, make and safeguard complexity, measuring accuracy is low, and application places is restricted.
Summary of the invention
The purpose of this utility model is to overcome the weak point that exists in the above-mentioned technology, a kind of compact conformation, reasonable in design is provided, the moving equipment of this hydraulic generator rotor dish is in hydraulic generator maintenance and installation process, not only axle system is not subjected to axially and diametral interference, and jiggering precision and efficient height, and rest point is accurate, manufacturing and easy to maintenance, the measuring accuracy height, gear range is wide, and rotating speed is the hydraulic generator electric barring equipment stably.
In order to achieve the above object, the technical solution adopted in the utility model is: comprise jiggering frame, drive motors and control cubicle, retarder-equipped drive motors symmetry is installed in jiggering frame upper surface, the jiggering frame is installed on the generator upper bracket, the end of decelerator is equipped with pinion, the engagement of pinion and jiggering gear wheel, jiggering gear wheel are fixed on the generator rotor shaft upper end, and control cubicle is connected with transducer on being installed in the turning gear main frame by lead and drive motors.
The utility model has the advantages that:
1, the utility model compact conformation, reasonable in design, the moving equipment of this hydraulic generator rotor dish is in hydraulic generator maintenance and installation process, not only axle system is not subjected to axially and diametral interference, and jiggering precision and efficient height, rest point is accurate, manufacturing and easy to maintenance, the measuring accuracy height, gear range is wide, and rotating speed is steady, installation, dismounting, control and simple to operation, optimize operational environment, improved working condition, reduced labour intensity, work quality and operating efficiency improve greatly, the cost performance height;
2, mechanical structure is simple, and electrical source of power is little, drives steadily reliably, and rotating speed is even, and rest point is accurate, because the principle of its moment of couple effect, the radial and axial interference of macro-axis is little, the measuring accuracy height;
3, the motor in the barring mechanism does not rotate with mechanism, and complete machine weight is by jiggering frame burden, and its rotating speed is steadily releived, and can remain on the data that accurately read each Along ent of macro-axis under the situation of continuous rotation, and is convenient and swift.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
By Fig. 1-Fig. 3 as can be known, the utility model comprises jiggering frame 1, drive motors 2 and control cubicle 8, drive motors 2 symmetries that decelerator 3 is housed are installed in jiggering frame 1 upper surface, jiggering frame 1 is installed on the generator upper bracket 7, the end of decelerator 3 is equipped with pinion 4, pinion 4 and 5 engagements of jiggering gear wheel, jiggering gear wheel 5 is fixed on the generator rotor shaft upper end, and control cubicle 8 is connected with transducer on being installed in the turning gear main frame by lead 9 and drive motors 2.
The utility model mainly comprises jiggering frame 1, drive motors 2 and control cubicle 8, reductor 3, pinion 4 and gear wheel 5 are formed reducing gear, jiggering frame 1 is installed on the hydraulic generator upper bracket 7, according to the difference of driving torque, can adopt 2,4,6 drive motors 2 symmetries of being furnished with decelerator 3 to be installed in jiggering frame 1 upper surface respectively.In the end of decelerator 3 pinion 4 is installed, these 2,4,6 pinions 4 mesh with jiggering gear wheel 5 simultaneously, the radially couple that this installation and the kind of drive can be cancelled out each other and be produced in the transmission, improved transmission accuracy, reducing gear is to adopt reductor and gear pair to finish deceleration, and wherein gear wheel puts together on the upper end of rotor 6.Control cubicle 8 is connected with transducer on being installed in the turning gear main frame by lead 9 and drive motors 2, the startup of control cubicle 8 controlling and driving motors 2 and stopping, behind electric motor starting, by reducing gear slow down and with transmission of power to generator amature 6, the rotating speed of rotor 6 is that rotating speed is 1r/15min, when finishing jiggering, the braking system braking.In whole device, the motor 2 in the barring mechanism does not rotate with mechanism, and complete machine weight is by jiggering frame 1 burden.
