Abstract
The invention relates to repair equipment for a shaft diameter of a high-temperature high-pressure steam turbine rotor, which comprises a handle, a platform and an electric grinder and is characterized in that the platform is provided with an electric grinding hole; the upper surface of the electric grinding hole is connected with a rotatable regulating ring by a gland; the regulating ring is connected with a lifting sleeve by an internal screw thread; the upper end of the lifting sleeve is connected with an electric grinder clamp by a connecting shaft; the electric grinder is inserted on the lifting sleeve and is clamped and fixed by the electric grinder clamp; bent plates are respectively mounted on the two sides of the platform; each of two ends of each bent plate is respectively connected with a roller carrier by a hinge pin; two rollers are assembled on each roller carrier. The repair equipment for the shaft diameter of the high-temperature high-pressure steam turbine rotor has the advantages that a welding repairing position of the shaft diameter of the steam turbine rotor can be rapidly processed; the height of the electric grinder can be regulated by the fine screw thread on the regulating ring, that is the amount of feed can be regulated; after being processed, the surface of the shaft diameter has a good effect; a good foundation is laid for final finish machining; the repair period of the shaft diameter of the steam turbine rotor is obviously shortened; manpower and material resources are reduced; the repair equipment is suitable for the technical requirement of a power plant for rapid overhaul.
Description
Technical field
The invention belongs to a kind of prosthetic device of plant equipment, particularly a kind of prosthetic appliance of the turbine rotor diameter of axle of using in power plant steam turbine high-temperature, all kinds of repairing rotors of high pressure.
Background technology
At the turbine system in power plant and all kinds of rotors of steam generator system (high temperature particularly, high pressure cylinder body internal rotor), after certain life cycle, diameter of axle surface can be due to wearing and tearing and erosion, and high temperature, the distortion causing under hyperbaric environment, diameter of axle circularity declines, there is rotor running bad phenomenon, need to repair grinding to rotor diameter of axle surface, the problem existing is at present: (1) is because the rotor diameter of axle is generally in φ 300mm-φ 500mm left and right, a large like this diameter surface, adopt traditional hand lapping, not only time-consuming but also require great effort, need a large amount of mill-hands, and the very difficult work quality that guarantees, the maintenance milling time in power plant is generally several days very short times simultaneously, like this, the job schedule of grinding to each maintenance is brought difficulty, also give and manufacture, transport is brought difficulty.(2) current, the maintenance of most of turbine rotor diameter of axle adopts repair welding, manual electric mill or angle mill polishing, underhand polish more, and inefficiency, can not adapt to the specification requirement of power plant Quick overhaul, and some part can not reach reparation object.
Summary of the invention
The prosthetic appliance that the object of this invention is to provide a kind of high temperature, the high-pressure turbine rotor diameter of axle, on the rotor diameter of axle being placed on after dismounting, start electric mill, mix up stock removal, hand-held hand propelled, height point after repair welding is carried out to grinding, also can carry out grinding to the high point of the deformation of the diameter of axle itself, the depth of cut can be adjusted according to the difference data different from the diameter of axle 0 basal plane, quick repairing rotor diameter of axle surface and weld high point, efficiency and precision is all repaired higher than traditional Manual angular mill, significantly shortens the time between overhauls(TBO), adapts to the specification requirement of power plant's Quick overhaul.
The object of the invention is to be achieved through the following technical solutions: it comprises handle, platform and electric mill, it is characterized in that: electric mill hole is set on platform, on electric mill hole, by gland, connect rotating adjusting ring, adjusting ring connects lifting cover by internal thread, lifting set upper side connects electric mill by connecting axle and presss from both sides, electric mill is installed on lifting and puts, and by electric mill, is pressed from both sides and is fixedly clamped; In platform both sides, bent plate is installed respectively, the two ends of each bent plate respectively connect a turning rolls by bearing pin, two rollers of each turning rolls assembling.
Good effect of the present invention is: this prosthetic appliance is on the turbine rotor diameter of axle, hand-held hand propelled, is simple and easy to use; By turn adjusting ring, make lifting cover rise or decline, realize the adjusting of stock removal; Variable-angle between four groups of rollers, thereby adapt to different diameter of axle processing reparations; Easily, easily to welding high point, wash away high point and the high point of diameter of axle distortion carries out rapid stock-removal, efficiency and precision is all repaired higher than traditional Manual angular mill, significantly shortens repairing efficiency, adapts to the specification requirement of power plant Quick overhaul.

Fig. 2 is structural front view of the present invention (grinding schematic diagram).
Fig. 3 be Fig. 2 top view.
Fig. 4 is the left view (motion schematic diagram) of Fig. 2.
Fig. 5 is that electric mill is assembled in the structure cutaway view on platform.
The specific embodiment
See Fig. 1-5, concrete structure of the present invention is as follows: electric mill hole is set on platform 2, on electric mill hole, by bolt 15, is fixedly connected with gland 8, push down the outer chimb of adjusting ring 3 by the pressure mouth of gland 8, between the two circumferentially, radially all have slight clearance, realize adjusting ring 3 and can rotate; Adjusting ring 3 connects lifting cover 4 by internal thread, and lifting is overlapped 4 upper ends and by connecting axle 14, connected the electric mill folder 5 of two lobes, and electric mill presss from both sides 5 open end connecting bolt and screws nut 7; Electric mill 6 is installed on lifting cover 4, presss from both sides 5 be fixedly clamped by electric mill; In platform 2 both sides, bent plate 9 is installed respectively, the two ends of each bent plate 9 respectively connect a turning rolls 11 by bearing pin, assemble two rollers 12 on each turning rolls 11.In platform 2 both sides, be fixedly connected with handle 10 simultaneously.
Operation principle:
1. hand-held
As Fig. 1, by this prosthetic appliance, on the turbine rotor diameter of axle, right-hand man controls respectively the handle 10 of respective side, and hand-held handle 10 promotes, and can realize the reciprocating motion of this equipment on the diameter of axle, as Fig. 3.
2. stock removal regulates
As Fig. 5, rotating adjusting ring 3 makes lifting cover 4 rise or decline, realize the adjusting of stock removal, stock removal is determined according to actual conditions, be material properties, case hardness etc., rotate the regulated quantity of adjusting ring 3 every circles, can determine by the pitch of screw thread between adjusting ring 3 and lifting cover 4, different thread pitch is determined different regulated quantitys.
3. tackle the different diameters of axle
Between turning rolls 11 and bent plate 9 due to assembling roller, adopt non-locate mode connection, the variable-angle between four groups of turning rolls, so only need this equipment can start grinding across being placed on the different diameters of axle.
