Abstract
The utility model relates to the rotator hoisting device of a high power heavy duty steam turbine which is characterized in that: the utility model comprises a banding ring, a press ring and a bolt. The inner ring of the banding ring is provided with stepped appearance inside hole whose step is provided with screw hole. The two sides of the outer ring of the banding ring are provided with lift eyes. The press ring is circle shaped and is divided into plurality pieces of press ring plate which is provided with through hole, the outer ring of the press ring matches the inner ring of the banding ring, and the bolt crosses the press ring plate and fixes the press ring plate on the banding ring. The utility model has the advantages of simple structure, convenient operation, stable performance and is safe and reliable, and therefore is suitable for the rotator of the steam turbine whose head face flange diameter is larger than the neck journal, particularly suitable for occasions where the head face flange diameter is slightly larger than the neck journal and the head face of the rotator of the steam engine cannot be connected with the hole.
Description
(1) technical field
The utility model relates to high-power heavy steam turbine rotor lifting tool.
(2) background technology
High-power heavy turbine rotor is bulky, and tens of tons that weigh are very high to safety, reliability requirement during handling.Welding is during turbine rotor, need be with rotor by the horizontality upset for vertical state handling butt welding to the jig, set level again after the transfer of more vertical rotor being sling after welding.The rotor that one group of through hole is arranged for the end face flange usually can vertically lift by crane with a lifting of bolt butt joint flange at rotor end-face.But the turbine rotor of certain model, there is not the hole on its end face flange, as use plain flange to lift by crane, then need the rotor blank size is made bigger modification, amplify the end face flange diameter, get out the technology screw, in subsequent handling, again the surplus of amplifying is removed then, so just cause material and the waste on man-hour.
(3) summary of the invention
The purpose of this utility model is to provide a kind of high-power heavy turbine rotor vertical lifting tool, this lifting tool is specially adapted to the end face flange does not have butt hole, the end face flange diameter is slightly larger than the turbine rotor of axle journal, this lifting tool is simple in structure, easy to operate, safe and reliable, good stability.
The utility model is achieved in that the vertical lifting tool of a kind of high-power heavy turbine rotor, it is characterized in that: comprise banding circle, pressure ring, bolt, have the stepped appearance endoporus on the banding circle inner ring, have screw on the step of stepped appearance endoporus, hanger is equipped with in both sides, banding circle outer ring; Pressure ring is an annular, and pressure ring is divided into some pressure ring sheets, has through hole on the pressure ring sheet, matches with banding circle stepped appearance inner ring in the pressure ring outer ring, and bolt passes the pressure ring sheet and is fixed on the banding circle.
Described pressure ring is divided into two, three or four pressure ring sheets.
The utility model adopts a banding circle by the stepped appearance endoporus, be divided into the pressure ring sheet of multi-disc and the vertical lifting tool of turbine rotor that bolt is formed, solved the lifting turbine rotor problem under the situation of inconvenience butt joint lifting flange, have simple in structure, easy to operate, safe and reliable, the characteristics of good stability.The utility model is applicable to the turbine rotor of end face flange diameter greater than axle journal, and being specially adapted to turbine rotor end face flange does not have butt hole, and the end face flange diameter is slightly larger than the occasion of axle journal.
(4) description of drawings
Fig. 1 is the vertical lifting tool schematic perspective view of the utility model turbine rotor;
Scheme drawing when Fig. 2 is the lifting of the vertical lifting tool of turbine rotor.
Among the figure: 1 banding circle, 2 pressure rings (pressure ring sheet), 3 bolts, 4 hangers, 5 end face flanges.
(5) specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, Fig. 2, the vertical lifting tool of a kind of high-power heavy turbine rotor comprises banding circle 1, pressure ring 2, bolt 3, has the stepped appearance endoporus on banding circle 1 inner ring, have screw on the step of stepped appearance endoporus, hanger 4 fixedly is equipped with through welding in both sides, banding circle 1 outer ring.Pressure ring 2 is an annular, and pressure ring 2 is divided into some pressure ring sheets, is divided into two, three or four pressure ring sheets as pressure ring 2, and pressure ring sheet 2 is two in the present embodiment, is symmetry shape; Having through hole on the pressure ring sheet 2, matches with banding circle 1 stepped appearance inner ring in pressure ring 2 outer rings, and bolt 3 passes pressure ring sheet 2 and is fixed in banding circle 1.
Referring to Fig. 2, during lifting, earlier banding circle 1 being passed rotor end-face flange 5 puts down, put into pressure ring sheet 2 then successively and block axle journal, and fastening with bolt 3, turbine rotor end face flange 5 is pressed on the pressure ring 2 like this, and banding circle 1 and pressure ring 2 clamp rotor journal, banding circle 1 bears total weight, loads onto shackle and can vertically lift by crane rotor on banding circle hanger 4.
The utlity model has simple in structure, easy to operate, safe and reliable, the characteristics of good stability, be applicable to the turbine rotor of end face flange diameter greater than axle journal, being specially adapted to turbine rotor end face flange does not have butt hole, and the end face flange diameter is slightly larger than the occasion of axle journal.
Claims (2)
1. vertical lifting tool of high-power heavy turbine rotor, it is characterized in that: comprise banding circle, pressure ring, bolt, have the stepped appearance endoporus on the banding circle inner ring, have screw on the step of stepped appearance endoporus, hanger is equipped with in both sides, banding circle outer ring; Pressure ring is an annular, and pressure ring is divided into some pressure ring sheets, has through hole on the pressure ring sheet, matches with banding circle stepped appearance inner ring in the pressure ring outer ring, and bolt passes the pressure ring sheet and is fixed on the banding circle.
