Abstract
The invention discloses a special tool for manual turning of a steam turbine. The special tool comprises a handle, a straight gear installed on the handle, a U-shaped perforated support seat installed on the handle in a sleeving manner and used for fixing the position of the straight gear, a fixed base fixed on the U-shaped perforated support seat, and a slide base installed on the handle in a sleeving manner, wherein a nut is welded at one end of the handle or welded at each of the two ends of the handle. The special tool disclosed by the invention is simple in structure, and convenient to detach and install; an electric driving operation is not needed, thus the working efficiency of manual turning is improved; a rotor is turned 90 degrees in place every time, high efficiency and reliable accuracy are achieved, and the mechanical error generated during centring of the rotor of a steam-turbine generator due to a high jitter degree of rotor turning is eliminated; therefore, the numerical precision of centring is improved, the labour intensity of operating personnel is greatly reduced, and the personal injury accidents and equipment damage accidents generated during steel wire rope winding are avoided.
Description
Technical field
The present invention relates to mechanical equipment technical field, particularly to a kind of steam turbine Special hand turning tool.
Background technology
The operation 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 concrete operations, it is existing problems, such as, during Baicheng temperature of power plant steam turbine overhaul, in rotor centering central process, the same with most of power plant little units, the not dynamic rotor instrument of supporting special dish, on-the-spot from installation, put into operation, during overhaul, it is all adopt the dynamic rotor of steam turbo generator of following method dish: at the added good end face of steam turbine generator clutch and radial direction dial gauge, and debug check and correction respective value, after penetrating stop centering nylon pin, No. 2 bearing sections of stretching out to normal disk car owner's moving gear non-working surface diameter of axle are wound around multi-turn steel wire rope, driving driver control, use the driving hook dynamic rotor of lift wire line hitch dish, often dish dynamic 90 ° put in place after, will readjust and once be wrapped on the diameter of axle position of steel wire rope；Be wrapped on the diameter of axle steel wire rope position not to or dish move not in place, repeatedly adjust, operation is extremely loaded down with trivial details, and cooperate commander's driving driver's crawl operation, 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 result in and look for RC reading numerical error, directly influencing rotor looks for RC result inaccurate, or do over again and start anew, and other overhauling project can not be done during use driving simultaneously, waste station service, delay maintenance duration.Accordingly, it would be desirable to a kind of special hand turning tool.
Summary of the invention
It is contemplated that at least solve one of problems of the prior art.
One of the technical problem to be solved in the present invention is in that in solution jiggering process there is jiggering inconvenience, looks for the inaccurate problem of RC result.
For solving above-mentioned technical problem, the present invention provides a kind of steam turbine Special hand turning tool, boring a hole bearing, the firm banking being fixed on described U-shaped perforation bearing, the sliding bottom that is sleeved on described handle including handle, the spur gear being arranged on described handle, the U-shaped being sleeved on described handle for fixing described spur gear position, described handle one or both ends are welded with nut.
Further, described firm banking and sliding bottom are provided with fluting.
Preferably, described fluting is rectangle round end groove.
Further, described nut is set with staight shank fork spanner.
Further, described staight shank fork spanner is connected to extension bar.
Preferably, described nut adopts specification to be the hex nut of M36.
Preferably, the diameter of described handle is 51mm, and length is 1150mm.
The beneficial effects of the present invention is and provide a kind of steam turbine Special hand turning tool, present configuration is simple, easy accessibility, do not need driving electric operating, improve artificial disc car work efficiency, often dynamic 90 ° of dish puts in place, efficiency is high, accuracy is reliable, eliminate because the dynamic rotor shake degree of dish is big, 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, it is to avoid the personal injury accident produced during lay winding wire ropes and equipment damage accident.
Accompanying drawing explanation
Fig. 1 show the structural representation of a kind of steam turbine Special hand turning tool of the embodiment of the present invention.
Detailed description of the invention
The present invention is described in detail below in conjunction with specific embodiment.It should be noted that, what the combination of technical characteristic described in following embodiment or technical characteristic was not construed as isolating, they can be mutually combined thus reaching superior technique effect.
Embodiment
The present embodiment provides a kind of steam turbine Special hand turning tool, as it is shown in figure 1, include handle 1, the spur gear 2 that is arranged on described handle 1, the U-shaped being sleeved on described handle 1 for fixing described spur gear 2 position bore a hole bearing 31, the firm banking 32 being fixed on described U-shaped perforation bearing 31, the sliding bottom 4 that is sleeved on described handle 1.Handle 1 is of a size of φ 51 × 1150mm.
In the present embodiment, sliding bottom 4 can slide along handle 1, to adjust the distance between firm banking 32；The position of spur gear 2 and U-shaped perforation bearing 31 opposite handle 1 is fixed.Described firm banking 32 and sliding bottom 4 are provided with fluting 5, and fluting 5 is rectangle round end groove, and rectangle round end groove is for being fixedly connected firm banking 32 and sliding bottom 4 at other device by bolt.
In the present embodiment, it is welded with nut 11 at the two ends of described handle 1, it is also possible at left end or right-hand member one described nut 11 of welding of described handle 1, nut 11 is the hex nut of M36, and thickness is 22mm；Described nut 11 is set with the staight shank fork spanner (not shown) of a S46mm,；Described staight shank fork spanner is connected to the extension bar (not shown) of a φ 60 × 2000mm.
