Description
Technical field
The present invention relates to mechanical equipment technical field, more particularly to a kind of steam turbine Special hand turning tool.
Background technology
The operation principle and performance of barring gear：When barring gear works, motor passes through worm screw, worm screw wheel rim, active
Gear drives the canine tooth torus rotation on turbine rotor, to which disk moves rotor of steam turbo generator rotation.
But in current concrete operations, for example, when Baicheng temperature of power plant steam turbine overhaul, looked in rotor there are problem
During center, as most of power plant small units, there is no mating dedicated disk turn sub- instrument, scene from installation,
It puts into operation, during overhaul, is all that rotor of steam turbo generator is moved using the following method disk：It is held well in the restocking of steam turbine generator clutch
Face and radial dial gauge, and check and correction respective value is debugged, after penetrating stop centering nylon pin, in No. 2 bearing section of stretching out to normally
Multi-turn steel wire rope is wound on the jiggering driving gear non-working surface diameter of axle, driver control of driving a vehicle lifts steel wire rope using driving hook
Detain disk turn, often dynamic 90 ° of disk in place after it is necessary to readjusting the primary position for being wrapped in steel wire rope on the diameter of axle；It is wrapped in axis
Steel wire rope position is not pair on diameter or disk moves not in place, repeatedly to adjust, process is extremely cumbersome, and cooperate commander's driving driver's point
Dynamic operation, the personnel of participation are more；Drive a vehicle driver control overlong time it is too short, can all influence 90 °, 180 °, 270 °, 360 ° hundred
To divide meter reading, will all cause the reading numerical error at centering center, the result for directly influencing rotor centering center is inaccurate, or
Person does over again from the beginning, and using that cannot do other overhauling project when driving a vehicle simultaneously, wastes station service, delay maintenance duration.Cause
This, needs a kind of dedicated hand turning tool.
Invention content
The present invention is directed at least solve one of problems of the prior art.
It is inconvenient, centering center that one of the technical problem to be solved in the present invention is during solution jiggering that there are jiggerings
As a result inaccurate problem.
In order to solve the above technical problems, the present invention provides a kind of steam turbine Special hand turning tool, including handle, installation
Spur gear on the handle is sleeved on U-shaped perforation bearing, fixation for fixing the spur gear position on the handle
Firm banking, the sliding bottom that is sleeved on the handle on U-shaped perforation bearing, the handle one or both ends weldering
It is connected to nut.
Further, the firm banking is equipped with fluting with sliding bottom.
Preferably, the fluting is rectangle round end slot.
Further, it is set with staight shank fork spanner on the nut.
Further, it is connected with extension bar on the staight shank fork spanner.
Preferably, the nut uses specification for the hex nut of M36.
Preferably, a diameter of 51mm of the handle, length 1150mm.
The beneficial effects of the present invention are providing a kind of steam turbine Special hand turning tool, the configuration of the present invention is simple,
It is convenient for disassembly and assembly, it is not required to driving electric operating, improves artificial disc vehicle working efficiency, often disk moves 90 ° in place, efficient, accuracy
Reliably, it eliminates because disk turn son shake degree is big, the machine error that when rotor of steam turbo generator alignment generates greatly improves
The Numerical accuracy at centering center greatly reduces the labor intensity of operating personnel, avoids the people generated when lay winding wire ropes
Body injury accident and equipment damage accident.
