With reference to Fig. 1, Fig. 2, in some embodiments, the conical component of lifting device lifting is the tail cone 1 of aero-engine,
Lifting device includes hanging scaffold 2, suspension hook 6, the quantity at least two of suspension hook 6, such as the quantity of suspension hook 6 is in the embodiment of Fig. 1
Four, one end connection of each suspension hook 6 is located at the first connecting portion 4 of hanging scaffold 2, and first connecting portion 4 is equal along the first circumference of hanging scaffold 2
Even distribution, i.e., the angle that each first connecting portion 4 is separated by is equal, such as when only there are two first connecting portion 4, then and each first
Angle between interconnecting piece 4 is 180 °, and when there are three when first connecting portion 4, the angle between each first connecting portion 4 is
120 °, when there are four when first connecting portion 4, the angle between each first connecting portion 4 is 90 ° as shown in Figure 1, and so on,
The pulling force that equally distributed first connecting portion 4 distributes each suspension hook 6 is impartial, guarantees lifting, transfer and installation process
Stability；First connecting portion 4 can be clamping pin structure as shown in Figure 1, and but not limited to this.The other end of each suspension hook 6 is
Hook portion 61, for connecting conical component.Lifting device further includes centring means 5, and centring means 5 includes taper sheath 9, taper sheath 9
It is coaxially arranged with hanging scaffold 2.In assembly, the big end of tail cone 1 is connect with the hook portion 61 of suspension hook 6, the small end and taper sheath of tail cone 1
9 medial surface connection, the i.e. small end that is set in tail cone 1 of taper sheath 9, when lifting device lifting, transfer and installation tail cone 1, due to
The setting of suspension hook 6 and hanging scaffold 2 avoids tail cone 1 in axial shaking, and the taper sheath 9 of centring means 5 is to the small end of tail cone 1
Pressing force, tail cone 1 is avoided in radial shaking, to play the role of lifting centering.
With reference to Fig. 1, Fig. 2, in some embodiments, hanging scaffold 2 is provided centrally with screw threads for fastening structure 20, tight by screw thread
Fixing structure 20 applies pressing force to taper sheath 9, so that taper sheath 9 compresses the small end of tail cone 1.Although can also have other to fixed
The taper sheath 9 of center device 5 applies pressing force, and then the mode of centering is compressed to tail cone 1, fills for example, by using spring structure to centering
The taper sheath 9 for setting 5 applies pressing force.Beneficial effect using screw threads for fastening structure 20 is that screw threads for fastening structure 20 can be square
Just pressing force is adjusted, and structure is simple, be easily assembled, convenient for operation.Further, screw threads for fastening structure 20 can be such as Fig. 2
It is shown, using the screw fastening structure of the first screw 3, although the other ways such as structure can also be connected by screw bolts.Using spiral shell
The beneficial effect for clenching fixing structure is that screw fastening structure is more simple, and the part of use is few, and without twisting spiral shell from the other side
Mother, it is easy to operate.
With reference to Fig. 1, Fig. 2, Fig. 5, in some embodiments, lifting device further includes buffer stopper 7, one end of buffer stopper 7 with
The contact of first screw 3, the toe contact of the other end and taper sheath 9 prevent taper sheath 9 to increase the forced area of taper sheath 9
Small end forms stress and concentrates and influence fatigue life.Further, the material of buffer stopper 7 can be resin, using having for resin
Beneficial effect is that resin elasticity is good, i.e., cushion performance is good, and wear-resisting, is not likely to produce during stress and CONTACT WITH FRICTION broken
Bits, avoid buffer stopper 7 from generating the impurity such as clast in hoisting process and fall into tail cone 1.As shown in figure 5, the specific size of buffer stopper 7
Can be width is d2, and the width d3 of the groove for contacting with the first screw is slightly larger than the diameter of the first screw 3.
Referring to figs. 2 to Fig. 4, the side of the taper sheath 9 of centring means 5 is double-layer structure, and internal layer side 92 is by rubber material
It is made, to be preferably bonded the side of cone 1, the internal layer side 92 of rubber can be pasted onto outer layer side 91 by binder,
Outer layer side can offer observation window 12, and to observe tail cone 1, whether process is normal during the installation process, can monitor tail cone 1
Whether abnormal conditions in the installations such as installation site offset are occurred.As shown in figure 3, the specific structure size of taper sheath 9 can be
The Angular Dimension a of taper sheath 9 is equal to the coning angle of tail cone 1；End diameter the size d >=d2, d2 of taper sheath 9 are buffer stopper 7
Width can be calculated with placing buffer stopper, the height dimension h of taper sheath 9 and the d1 of diameter dimension according to the height of tail cone 1,
So that so taper sheath 9 can be made for tail cone 1 in the range of the end face of the small end of tail cone 1 just reaches (1/3~2/3) h
Pressing force it is moderate, avoid occurring pressing force it is excessive cause stress concentrate deformation or pressing force it is too small and centering effect is paid no attention to
The case where thinking.
With reference to Fig. 1, Fig. 2, in some embodiments, it includes outer ring that the example of the specific structure of hanging scaffold 2, which can be hanging scaffold 2,
21, hub 22 and spoke 23, outer ring 21 include the first circumference that first connecting portion 4 is distributed with, the axis of hub 22 with hang
The axis of disk 2 is overlapped, and one end of spoke 23 connects hub 22, and the other end connects outer ring 21.Although hanging scaffold 2 can also use other
Structure, such as solid disc structure.The setting of circle 21, hub 22 and spoke 23, so that hanging scaffold 2 is before meeting structural strength
It puts, reduces weight, realize lightweight.Specifically, the quantity of spoke 23 is identical as the quantity of suspension hook 6, spoke 23 and outer
The junction 231 of circle 21 is identical as the circumferential position of first connecting portion 4, and radial position can be identical or first connecting portion
4 are located at the external of radial direction.The beneficial effect of such setting is that spoke 23 can more effectively bear suspension hook 6 to hanging scaffold 2
Pulling force further enhances the structural strength and stability of hanging scaffold 2.Latch hook 13 can also be arranged in the outer ring 21 of hanging scaffold 2, for wearing
Cable wire is crossed to sling hanging scaffold.
With reference to Fig. 2, in some embodiments, the hook portion 61 of suspension hook 6 includes connecting hole, hook portion 61 and the big end of tail cone 1
Connection structure is that the threaded connection of above-mentioned connecting hole is passed through using the second screw 8.Although other connection types can also be used,
Such as card slot is arranged in the big end of tail cone 1, hook portion 61 is connected together with card slot.It is to connect using the beneficial effect of threaded connection
Reliably, and hook portion 61 is allowed to have the dimensions error, reduces the difficulty of processing of suspension hook 6.
From described above available, the lifting of aero-engine tail cone 1 is walked using the lifting device of above-described embodiment
Suddenly include:
1) when tail cone 1 is placed vertically, centring means 5 first is placed in the small end of tail cone 1, so that the internal layer of 9 rubber of taper sheath
Side 92 is fitted in the outer surface of tail cone 1；
2) sub-assembly of hanging scaffold 2, four first connecting portions, 4, four suspension hooks 6 is moved into 1 top of tail cone, with four the second spiral shells
At the technique screw hole for the big end that the hook portion 61 of four suspension hooks 6 is connected to tail cone 1 by nail 8；
3) buffer stopper 7 is placed at position shown in the upper diameter d of centring means 5；
4) the first screw 3 is tightened on hanging scaffold 2, buffer stopper 7 is pressed on centring means 5 by way of tightening screw thread
On, so that the taper sheath 9 of centring means 5 is pressed on the presumptive area of tail cone 1；
5) with the latch hook 13 and crane of four isometric cable wire connection hanging scaffolds 2, crane is operated by tail cone 1 and is moved to specific bit
It sets and is installed.
