Abstract
A turbine servicing turnover watt type device is composed by a hauling device and a lifting device. The hauling device is a hoister provided with a retainer component. The contact surface between the retainer and the main shaft of the turbine is provided with a roller and the upper part of the retainer is provided with a coil cable guide groove. The lifting device is provided with a base seat and a column is installed onto the base by bearings with a support pad in the center. The lifting arm is positioned on the support pad through pin groove and pin column and the column on the tail of the lifting arm is fixed with screw-nuts. The combination of the hauling device and the lifting device has advantages of easy operation, time and labor conservation and quickened maintenance work.
Description
This reality is novel to relate to a kind of specific purpose tool that overhauls steam turbine, and particularly a kind of bearing shell to turbine spindle is measured, when scraping, adjustment, turns over low brass to the main shaft top and hangs out used overhaul of steam turbine with turning over a watt device.
Power plant is when the maintenance steam turbine, to measure or scraping, adjustment the bearing shell of main shaft, need often upset low brass, in maintenance process, turn over watt is an arduous job, particularly light maintenance, the small distance because main shaft can only be sling, workpiece is heavy, the job site is narrow, especially bearing shell is taken out of from the bearing shell nest, it is more difficult to operate, and is easy to injure main shaft or bearing shell.
The purpose of this utility model is at the deficiencies in the prior art, has proposed a kind of employing mechanical system, turns over low brass to main shaft top and bearing shell is hung out used overhaul of steam turbine turn over a watt device.
The purpose of this utility model is achieved through the following technical solutions, a kind of overhaul of steam turbine is with turning over a watt device, it comprises draw-gear and boom hoisting, be characterized in: draw-gear is provided with a motor-operated reel, be provided with deceleration device between reel and the motor, reel is provided with the volume rope, its draw-gear also is provided with a retainer assembly, the face that retainer contacts with turbine spindle is provided with roller, the top of retainer is provided with volume rope gathering sill, boom hoisting is provided with base, column is installed on the base by bearing, and the column middle part is provided with back-up block, and lifting arm is installed on the back-up block by the cotter way pin, lifting arm cotter way pin is installed the back afterbody top of fulcrum, is provided with the feed screw nut who is installed on the column.Draw-gear and boom hoisting are separately positioned on the both sides of front cover main shaft in the steam turbine, the steel wire rope of draw-gear is pulled to horizontal level to two halves bearing shell faying face by the anchor clamps that are fixed on Shang watt, pull down and connect the bolt of going up lower bearing, the lifting arm tail end is inserted in the upright supports piece groove of hoisting apparatus, the upright supports piece that the straight pin of lifting arm is put into hoisting apparatus protrudes the cotter way of end, pass through rotary screw rod, screw mandrel withstands the tail end of lifting arm downwards, the lifting arm head is raised up, and the top bearing shell of slinging is removed; Hoisting ring is screwed in the lower bearing end, the roller at two angles of retainer contacts with turbine spindle, the steel wire rope of draw-gear is connected with suspension ring by the fixed wheel on the 3rd angle of retainer, change the force direction that is subjected to of bearing shell by retainer, start draw-gear, lower bearing is pulled out most, then stop traction, use the boom hoisting relay this moment, at following watt middle part hanger is installed, hanger is connected with lifting arm, and draw-gear and boom hoisting and usefulness turn over lower bearing to the main shaft top, adjust boom hoisting, the lower bearing of slinging shifts out bearing shell, measures or scraping, adjust.
The purpose of this utility model can also be come further realization by the following technical programs, and the optimum shape of retainer is a triangle, and two angles that contact with turbine spindle are provided with roller, and the 3rd angle is provided with fixed wheel.
The utility model adopts draw-gear and boom hoisting to be used, and bearing shell is taken out of from the bearing shell nest, and is simple to operation, protected main shaft and bearing shell, time saving and energy saving, improves workman's working environment, accelerated the maintenance progress.
