The device in the invention comprises a steel wire drawing frame, wherein the steel wire drawing frame is arranged on a support through a steel wire frame supporting plate and comprises a bottom plate; the bottom plate is provided with an adjusting device; a steel wire fixing frame is connected with the adjusting device; and the steel wire fixing frame is provided with a steel wire pulling block.
Description
Technical field
The present invention relates to a kind of steam turbine assembling and draw the steel wire centering apparatus.
Background technology
Steam turbine is as a high-precision equipment of HTHP, and in its assembling process, the position accuracy demand of impeller etc. is very high, so need one to assist the middle mode of looking for.Mode is during dummy shaft is looked in mainly the looking for of present domestic existence, promptly earlier through cylinder body with the dummy shaft centering, be located at the steam turbine cylinder center.Utilize again during it looks for the impeller of newly packing into.Mainly have following problem during the use dummy shaft is looked for: for avoiding dummy shaft because of long (steam turbine generally needs length more than 6 meters), descend because of its deadweight causes the middle quality of looking for that distortion causes, it is thicker that general dummy shaft is all done, to guarantee its rigidity.So dummy shaft is generally relatively heavier, relatively waste material; Guarantee axiality through equidistance radially because of in looking for the time, so high to the circumferential requirement on machining accuracy of dummy shaft, surface smoothness requires high, processing difficulties; For cooperating dummy shaft to use, two ends must have high accuracy to support, and each needs the false bearings of a special processing two ends; The adjustment dummy shaft is relatively wasted time and energy during the position.
Summary of the invention
The object of the invention provides a kind of steam turbine assembling to draw the steel wire centering apparatus exactly for addressing the above problem, and it is simple in structure, and is easy to use, more accurate when steel wire is adjusted.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
The steel wire centering apparatus is drawn in a kind of steam turbine assembling, and it comprises draws steel wire rack, and it is rack-mount to draw steel wire rack to pass through the steel wire rack gripper shoe; The said steel wire rack that draws comprises base plate, on base plate, is provided with adjusting device, and the fixation with steel wire frame is connected with adjusting device, on the fixation with steel wire frame, is provided with the steel wire pulling block.
Said adjusting device comprises that a pair of branch is listed in the vertical first adjustment plate and a pair of horizontal second adjustment plate that is distributed in the base plate upper and lower sides of base plate both sides; Two longitudinally the first adjustment plate outside be respectively equipped with first side guide, be respectively equipped with second side guide in the two second horizontal adjustment plate outsides; On each adjustment plate and each side guide, distribute and be connected one and adjust screw.
The said screw of respectively adjusting is connected with each adjustment plate through back-up block respectively.
Device of the present invention is mainly by drawing steel wire rack, steel wire rack gripper shoe, support etc. to form.Its medium-height trestle is mainly used in the adjustment of supporting total and the big position of horizontal direction; The steel wire rack gripper shoe is mainly used in connecting rack and the adjustment of drawing the big position of steel wire rack and vertical direction; Steel wire rack is mainly used in the horizontal vertical fine position of taut wire and structure.
Draw steel wire rack mainly to constitute by part base plate, the solid frame of steel wire, first side guide, second side guide, the first adjustment plate, the second adjustment plate, adjustment screw back-up block, steel wire pulling block, adjustment screw etc.
Be fixed on the steam turbine one end workbench through support during work, fixation with steel wire is placed a same device at the steam turbine other end on the steel wire pulling block, and steel wire passes the steel wire pulling block with calculating desirable weight taut wire.
The adjustment of steel wire position, coarse adjustment is through the whole horizontal level of adjustment support; Fine setting then utilizes draws the adjustment screw on the steel wire rack, promotes the first adjustment plate or the second adjustment plate carries out respectively vertically and the position of horizontal direction steel wire through tightening or unscrewing.
The invention has the beneficial effects as follows: steel wire is general thick to be 0.4-0.6mm, so the steel wire deadweight is very little, after the tightening force tension that calculates, the linearity of steel wire is well guaranteed; This device is than dummy shaft compact volume and convenience, and service condition is loose; Cost of manufacture is low, and requirement on machining accuracy is low, practices thrift a large amount of financial cost; Need not other auxiliary equipment; Easy when steel wire is adjusted, accurate.
