Abstract
The utility model relates to an on-site restoration self-adapting working platform for shaft neck strain of a low-pressure rotor for a steam turbine. The on-site restoration self-adapting working platform comprises a base, a horizontal adjusting screw, tracks, adjusting screw rods, a supporting adjusting rack, a lifting platform, argon cylinder fixing rings, safety protection railings and a movable soft ladder. The base is divided into an upper layer, a middle layer and a lower layer; bolts for adjusting the horizontal level are arranged at the four corners of the lower layer, front/rear adjusting screw rods are welded on a steel plate of the base, and front/rear tracks are welded at the two edges of the steel plate; the steel plate at the middle layer is welded with left/right tracks and left/right adjusting screw rods, track wheels are welded at the bottom part of the steel plate, and the bottom part of the steel plate is in contact with the track at the lower layer; the supporting adjusting rack is arranged between the upper layer and the lifting platform, the safety protection railings are arranged at the periphery of the lifting platform, the argon cylinder fixing rings are arranged at the two corners of the lifting platform, and the movable soft ladder is arranged at one side. The on-site restoration self-adapting working platform not only solves the problems that the working platform built on site is inflexible, is poor in safety performance and cannot carry out shaft neck restoration according to different height of the low-pressure rotor for the steam turbine on site, but also has the advantages of being safe as well as steady, being convenient for getting on/off, and being capable of adjusting the shaft neck restoration of the low-pressure rotor for the steam turbine in front-rear, upper-lower and left-right manners.
Description
Technical field
The utility model belongs to plant equipment site examining and repairing workbench.
Background technology
The steam turbine low-pressure rotor is the critical component of Turbo-generator Set.Because contingencies such as rotor journal is pulled, gouge, wearing and tearing usually can take place in a variety of causes such as manufacturing, installation or operation.The damage defect of axle journal, the even performance of oil film, the vibration performance of unit during the influence operation; Local damage causes stress to concentrate, and influences rotor strength; These all will bring serious harm to Turbo-generator Set safety.The steam turbine low-pressure rotor journal is pulled field repair, is a very significant job.It substantially all is scaffold that existing steam turbine low-pressure rotor journal is pulled the field repair workbench, not only the need of work that can not repair with on-the-spot axle journal and front and back, up and down, about adjust, and poor stability, personnel, equipment, instrument etc. drop easily, pull field repair work for the steam turbine low-pressure rotor journal and have caused great inconvenience.
Summary of the invention
In view of above-mentioned, the purpose of this utility model aims to provide a kind of steam turbine low-pressure rotor journal and pulls field repair self adaptation workbench.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of steam turbine low-pressure rotor journal is pulled field repair self adaptation workbench, comprises that base, horizontal set screw, front and back track, left and right sides track, front and back regulate leading screw, left and right adjusting leading screw, Adjustable supporter, hoistable platform, argon bottle fixed bit, safety guide rail, up and down rope ladder up and down.Base divides three layers of upper, middle and lowers, and four jiaos of bolts that the adjusting level is arranged of lower floor are welded with on the base steel plate and can regulate leading screw in front and back, track before and after two edges of plate is welded with; Middle level steel plate welding left and right sides track and left and right adjusting leading screw, steel plate bottom welded rails wheel contacts with the lower floor track; Between upper strata and hoistable platform Adjustable supporter is arranged, around the hoistable platform safety barrier is arranged, two jiaos have the argon bottle retainer ring, and a side has movable rope ladder.
The beneficial effect of advantage of the present utility model and generation:
The utility model can adapt to the steam turbine low-pressure rotor journal reparation of differing heights, and safety and firmness is easy for going up and down, works on platform as ground, and installing/dismounting is efficient and convenient, has created good condition for the axle journal repair, has promoted reparation speed greatly; Solved the on-the-spot workbench poor stability of building, dumb, can not have safety and firmness with the problem of the steam turbine low-pressure rotor journal of field repair differing heights, easy for going up and down, front and back, up and down, the advantage of left and right adjusting.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is Fig. 1 lower floor vertical view.
Fig. 3 is Fig. 1 middle level vertical view.
The specific embodiment
As Figure 1-3, a kind of steam turbine low-pressure rotor journal is pulled field repair self adaptation workbench, comprises that base 1, horizontal set screw 2, front and back track 3, left and right sides track 4, front and back regulate leading screw 5, left and right adjusting leading screw 6, Adjustable supporter 7, hoistable platform 8, argon bottle fixed bit 9, safety guide rail 10, up and down rope ladder 11 up and down.Area and on-the-spot space size according to the required workbench 8 of the steam turbine low-pressure rotor journal of each reparation install base 1.Three layers of 1 fen upper, middle and lowers of base, four jiaos of bolts 2 that the adjusting level is arranged of lower floor's base, base 1 thickness 20.00mm, width 500.00mm, leading screw 5 welding can be regulated in the steel plate of length 2500.00mm and front and back, track 3 before and after two edges of plate is welded with can be regulated leading screw 5 and can regulate any the moving in middle level base front and back in the 1200.00mm scope.The thick 20.00mm of middle level base, width 2000.00mm, the steel plate of length 2500.00mm is made, middle level steel plate welding left and right sides track 4 and left and right adjusting leading screw 6, track and adjusting leading screw direction and lower bottom base track, leading screw are vertical; Steel plate bottom welded rails wheel 12 contacts with the lower floor track.Same and the middle level base cooperation of upper strata base, left and right adjusting leading screw 6 can make the upper strata base adjustable in the 600.00mm scope of the left and right sides.8 of upper strata base and hoistable platforms have Adjustable supporter 7, and the upper strata base is fixed with hoistable platform 8.Hoistable platform 8 areas are 20.00mm * 2000.00mm * 2000.00mm's, the oscilaltion amplitude is 1000.00mm, the detachable safety barrier 10 of plug-in type is arranged around the hoistable platform 8, two jiaos have argon bottle retainer ring 9, one side has the up and down rope ladder 11 of length adjustable, makes things convenient for about the staff.
