All being installed with lower hanger 5 in hole 15, the end of described lower lifting rope 3 is connected with lower hanger 5.
When using above-mentioned lifting tool lifting turbine rotor 10, after lower lifting rope 3 is enclosed within turbine rotor 10, under making
The end of lifting rope 3 is connected with lower hanger 5, the end of lifting rope 2 after being enclosed within the suspension hook 16 of hanging device by upper lifting rope 2, on making
Portion is connected with upper hanger 4, starts hanging device, then turbine rotor 10 is upwards sling by hanging device by lifting tool.On
Stating steam turbine rotor lifting tool and eliminate upper hanger of the prior art and the plate structure extended up and down of lower hanger, the application is led to
Cross be provided for connecting in the centre of web 13 supporting crossbeam 1 lifting rope 2 upper hanger 4 and under connecting lifting rope 3
Lower hanger 5, thus shorten the whole height of lifting tool, at least shorten 1-2 rice, and then add lifting tool to vapour
The sling height of turbine wheel so that this lifting tool is simultaneously suitable for short factory building and high factory building, is particularly well-suited to overhead traveling crane, driving
The short factory building of limited height, applied range.It addition, the overall structure of this lifting tool is optimized so that it is cost is lower,
Reduce the cost of investment in power plant.
In the present embodiment, described upper flange 11 and web 13, lower wing plate 12 and web 13 are for being welded and fixed, it is also possible to manufacture
Integral part, when upper flange 11, lower wing plate 12 and web 13 are manufactured into integral piece, described support crossbeam 1 preferably employs work
Word bracing members.It addition, the lower surface of described lower wing plate 12 is a horizontal-extending plane, it is simple to clear, observe lifting intuitively
Whether the lower end of instrument can encounter the blade 103 being arranged on turbine rotor.
Further, in order to enable turbine rotor to lift by crane the most vertically during lifting, as it is shown on figure 3, institute
State through hole 14 have two, left and right be arranged side by side, described lower through-hole 15 also has two, left and right is arranged side by side；Meanwhile, along propping up
The length bearing of trend of support crossbeam 1, two upper through holes 14 are between two lower through-holes 15.Correspondingly, it is fixed on through hole
Upper hanger 4 in 14 also has two, and the upper lifting rope 2 being connected with upper hanger 4 also has two；It is fixed in lower through-hole 15
Lower hanger 5 also has two, and the lower lifting rope 3 being connected with lower hanger 5 also has two, and lower lifting rope 3 is enclosed within turbine rotor two ends
Axle journal 102 on.
Further, as shown in Figure 3 and Figure 4, described upper hanger 4 is a connecting shaft front and back extended, and this connecting shaft is located in
Being welded and fixed in upper through hole 14 and with web 13, the two ends of described upper lifting rope 2 are provided with and lay respectively at both sides before and after upper flange 11
Upper collar portion 21, on this, collar portion 21 is enclosed within connecting shaft, thus is connected with connecting shaft by the suspension hook 16 of lifting appliance.
Described lower hanger 5 is a connecting plate front and back extended, and this connecting plate is welded and fixed with web 13, two ends before and after described connecting plate
Being respectively connected with shackle 6, the two ends of described lower lifting rope 3 are provided with the ring portion 31 of trapping laying respectively at lower wing plate 12 both sides front and back, under this
Collar portion 31 is enclosed within the button 61 of shackle 6, thus is connected with connecting plate by turbine rotor.It addition, described shackle 6
Being a kind of rigging, for standard component, mainly button 61 and the latch 62 connecting button 61 two ends by generally taking the shape of the letter U are constituted,
And latch 62 with button 61 for removably connecting.
Further, before and after described upper hanger 4, two ends are respectively connected with baffle plate 7, with limit upper lifting rope 2 on upper hanger 4 to
It is sliding out outward.It addition, described upper hanger 4 is removably connected by multiple screws 8 with baffle plate 7；Therefore, when inconvenience is by upper
When lifting rope 2 pries between baffle plate 7 and upper flange 11, can will unscrew screw 8, baffle plate 7 is pulled down, afterwards can be easily by upper
Lifting rope 2 pries between baffle plate 7 and upper flange 11, then installs baffle plate 7, tightens screw 8.
Further, in described two upper lifting ropes 2, at least connect on a lower lifting rope 3 and have levelling gear 9, by this tune
The levelness of flattening mechanism 9 adjustable turbine rotor, one end is high, one end is low to prevent turbine rotor from occurring during lifting
Phenomenon, to ensure that turbine rotor can smoothly be lifted by crane vertically.As shown in Figure 3 and Figure 4, described levelling gear 9
Including screw rod 91, sleeve pipe 92 and lower screw rod 93 the most successively, the upper end of upper screw rod 91 directly and is arranged on lower hanger 5
On the button 61 of snap close be welded and fixed, the lower end of lower screw rod 93 is welded on the button 61 of a snap close again, the button of this snap close
Body 61 is connected with lower lifting rope 3；Offer in described sleeve pipe 92 the contrary upper screwed hole of thread rotary orientation (also referred to as orthodontic) and under
Screwed hole (is also referred to as set one's teeth on edge), described upper screw rod 91 and the upper screwed hole threaded engagement of sleeve pipe 92, lower screw rod 93 and sleeve pipe 92
Lower screwed hole threaded engagement；Therefore, during rotating casing 92, upper screw rod 91 and lower screw rod 93 can move towards or move dorsad,
Thus the lower lifting rope 3 sling height to turbine rotor of regulation, and then adjust the levelness of turbine rotor.
In sum, the steam turbine rotor lifting tool that the application relates to has the advantage that
1, in the case of not changing support crossbeam 1 I-shaped cross-sectional structure intensity, upper hanger 4 and lower hanger 5 are all located at
Support the centre of the web 13 of crossbeam 1, thus shorten the whole height of lifting tool, at least shorten 1-2 rice, Jin Erzeng
Add the lifting tool sling height to turbine rotor so that this lifting tool is simultaneously suitable for short factory building and high factory building, especially
It is applicable to the short factory building that overhead traveling crane, ride height are limited.
2, after the height reduction of steam turbine rotor lifting tool, its structure have also been obtained simplification, so that lifting turbine rotor
Weight and the cost of instrument all reduce.
3, relative in prior art upper hanger and lower hanger be all welded on the upper flange of I-steel and the structure of the side of lower wing plate and
Speech, in the application, upper hanger 4 and lower hanger 5 are all welded on the web 13 of I-steel, with the upper flange 11 of I-steel
Not being directly connected to lower wing plate 12, therefore, the application does not destroys the upper flange 11 of I-steel and the stress distribution shape of lower wing plate 12
State；For I-steel, it is easiest to cause stress to concentrate at upper flange 11 and lower wing plate 12, therefore all of stress of the application
Point all concentrates on the inside of I-steel, rather than the outer edge of I-steel, thus improve the overall knot of steam turbine rotor lifting tool
Structure intensity.
4, the lower surface of the lower wing plate 12 of I-steel is plane, does not has any protruded object, therefore does not allows when lifting by crane turbine rotor
Easily encounter the blade being arranged on turbine rotor, meet working specification.
So, the utility model effectively overcomes various shortcoming of the prior art and has high industrial utilization.
Above-described embodiment only illustrative principle of the present utility model and effect thereof, not for limiting the utility model.Any
Above-described embodiment all can be modified under spirit and the scope of the present utility model or change by those skilled in the art.
Therefore, such as art has usually intellectual without departing from the spirit disclosed in the utility model with under technological thought
All equivalences completed are modified or change, and must be contained by claim of the present utility model.
