The utility model discloses simple structure, easy dismounting, the electrically -operated that need not drive a vehicle has improved artifical barring work efficiency, every set is moved 90 and targets in place, efficient, the degree of accuracy is reliable, has eliminated because of set operation shake degree is big, the mechanical error that produces during the alignment of turbo generator rotor has greatly improved the numerical value accuracy at alignment center, greatly reduced operating personnel's intensity of labour, the easy dismounting 0 and the equipment damage accident of production when having avoided winding wire rope.
Description
Technical field
The utility model relates to mechanical equipment technical field, particularly a kind of steam turbine Special hand turning tool.
Background technique
The working principle of barring gear and performance: during barring gear work, motor drives the canine tooth torus on turbine rotor to rotate by worm screw, worm screw wheel rim, driving gear, thus the dynamic rotor of steam turbo generator of dish rotates.
But in current specific operation, be existing problems, such as, during the overhaul of Baicheng temperature of power plant steam turbine, in rotor centering central process, the same with most of power plant little unit, supporting special dish does not move rotor instrument, on-the-spot from installation, put into operation, between overhaul time, all adopt following method dish to move rotor of steam turbo generator: at the added good end face of steam turbine generator clutch and radial dial gauge, and debugging check and correction respective value, after penetrating stop centering nylon pin, to the normal disk car owner moving gear non-working surface diameter of axle, multi-turn wire rope is wound around No. 2 bearing sections of stretching out, driving driver control, driving hook lift wire line hitch dish is used to move rotor, often dish dynamic 90 ° put in place after, the position being once wrapped in wire rope on the diameter of axle will be readjusted, to be wrapped on the diameter of axle wire rope position not to or dish dynamic not in place, repeatedly adjust, operation is very loaded down with trivial details, and cooperatively interact the operation of commander's driving driver crawl, and the personnel of participation are more, driving driver control overlong time is too short, capital affects the dial gauge reading of 90 °, 180 °, 270 °, 360 °, all will cause and look for RC reading numerical error, directly having influence on rotor looks for RC result inaccurate, or do over again and start anew, and use during driving can not do other overhauling project simultaneously, waste station service, delays maintenance duration.Therefore, a kind of special hand turning tool is needed.
Model utility content
The utility model is intended at least solve one of problems of the prior art.
One of the technical problems to be solved in the utility model is to there is jiggering inconvenience in solution jiggering process, look for the inaccurate problem of RC result.
For solving the problems of the technologies described above, the utility model provides a kind of steam turbine Special hand turning tool, comprise handle, the spur gear be arranged on described handle, be sleeved on the U-shaped perforation bearing for fixing described spur gear position on described handle, fixed base, the sliding bottom be sleeved on described handle be fixed on described U-shaped perforation bearing, described handle one or both ends are welded with nut.
Further, described fixed base and sliding bottom are provided with fluting.
Preferably, described fluting is rectangular round end groove.
Further, described nut is set with staight shank solid wrench.
Further, described staight shank solid wrench is connected with extension bar.
Preferably, described nut adopts specification to be the hexagon nut of M36.
Preferably, the diameter of described handle is 51mm, and length is 1150mm.
The beneficial effects of the utility model there are provided a kind of steam turbine Special hand turning tool, the utility model structure is simple, easy accessibility, do not need electric operating of driving a vehicle, improve artificial disc car working efficiency, often dynamic 90 ° of dish puts in place, efficiency is high, degree of accuracy is reliable, eliminate because coiling rotor shake degree large, the machine error produced during rotor of steam turbo generator alignment, greatly improve and look for RC Numerical accuracy, greatly reduce the labor intensity of operator, the personal injury accident produced when avoiding lay winding wire ropes and equipment damage accident.
Accompanying drawing explanation
