The special lifting device provided by the utility model can improve the utilization rate of the lifting machine.
Description
Technical field
The utility model belongs to the wind power generating set special hanger for hoisting.
Background technology
The equipment hoisting process of wind power generating set need be used the general or special purpose crane tool of large-tonnage and cooperate; These cooperate the selection of elevator machinery to take into account convenience, the safety of cutting between appearance and blower fan usually; Factors such as the weight of key component cabin, tower tube and height in place, workyard; Wherein crawler crane, full ground hoisting crane, automobile crane are used comparatively general in the wind power generating set equipment hoisting for these; The full ground of large-tonnage hoisting crane has occupied leading position in the wind energy turbine set installation process in mountain and hill area, high mountain zone; Like the heavy 41.5t in cabin in certain 1MW Fan Equipment, height 51m in place, crawler crane or the full ground of the 500t hoisting crane of selecting 250t and above rated load weight usually are as the equipment hoisting cooperative mechanical.In the practice of construction process because the duration is tight, the operation place is little; Distance is not very good than far away and construction time road conditions again between each blower fan; Crawler crane is not because to need dismounting to be combined in the high mountain wind energy turbine set be very to be suitable for, to the full ground of large-tonnage hoisting crane regular meeting run into the required full ground of this large-tonnage hoisting crane of lifting can not be in the required time period just idle or occur since tonnage more the height lease valency that causes more less relatively of large resource lack the economy consideration.
Summary of the invention
The lower deficiency of degree of utilization of elevator machinery when lifting in order to overcome existing wind power generating set, the utility model provides a kind of wind power generating set special hanger for hoisting that improves the elevator machinery degree of utilization.
The utility model solves the technical scheme that its technical matters adopted:
A kind of wind power generating set special hanger for hoisting, said suspender comprises built H beam and suspension hook, said suspension hook is installed at the middle part of said built H beam, installs on the said built H beam with the rigging of elevator machinery and hangs the bonded assembly hanger.
Further, said hanger is installed at the two ends of said built H beam.
Further again, said hanger is installed at the middle part of said built H beam.
Further, the I-beam section welding that described built H beam is I40 by 2 models forms, and with steel plate composite beam is sealed into the box shoulder pole girder.
The technical conceive of the utility model is: the two-shipper that institute's design-calculated wind-force wind-powered electricity generation unit special hanger can be fit to heaviest piece blower fan cabin lifts (or poly-machine lifting crane) this suspender capable of using again effectively to be reduced the lifting of impeller assembly is carried out in the requirement that cooperates the loop wheel machine lifting altitude smoothly, realizes the suspender function diversity.Lift preceding 2 cooperation elevator machineries in the heaviest piece cabin and can carry out the lifting of wind turbine alone, accelerated wind energy turbine set single-piece construction speed greatly.
The beneficial effect of the utility model mainly shows: in the practice of construction process, run into required hoister in large tonnage tool can not the required time period rent and have on the leasing market 2 little other elevator machineries of tonnage level maybe can rent but since loop wheel machine tonnage large resource lack the high construction cost of value of leass relatively and can't bear; Design and produce suitable special hanger; Lift the lifting that just can accomplish blower fan heaviest piece cabin through 2 little other elevator machineries of tonnage level; And the lifting of the foundation ring of blower fan, tower tube, impeller assembly can have the separate unit elevator machinery to accomplish; The whole wind electric field has promptly had 2 elevator machineries like this; 2 loop wheel machines cooperate completion in place when the lifting in every typhoon machine heaviest piece cabin; Remove to shift fast separately in addition and carry out the lifting of wind turbine, manoevreability improves greatly, and whole wind electric field progress is accelerated greatly.Utilize this to take back the special hanger that changes suspension hook from the practice of construction situation, solved the unstable situation of the big lifting of on-the-spot wind-force, lifting distribution of load can be effectively controlled.Rationally use 2 elevator machineries on the contrary than construction organization design desired 1 more the large-tonnage elevator machinery have more economy, integral construction cost, progress have obtained actv. control.
Description of drawings
Fig. 1 is the scheme drawing of blower fan generator set special hanger for hoisting.
Fig. 2 is the A-A section drawing of Fig. 1.
Fig. 3 is a cabin lifting elevation drawing.
Fig. 4 is the birds-eye view of Fig. 3.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1～Fig. 4; A kind of wind power generating set special hanger for hoisting; Said suspender comprises built H beam 1 and suspension hook 2, and said suspension hook 2 is installed at the middle part of said built H beam 1, installs on the said built H beam 1 with the rigging of elevator machinery and hangs bonded assembly hanger 3.
Said hanger is installed at the two ends of said built H beam 1.Adopt two elevator machineries to work simultaneously.Said hanger is installed at the middle part of said built H beam, also can adopt three even more a lot of heavy-duty machine tool to work simultaneously.。
The I-beam section welding that described built H beam is I40 by 2 models forms, and with steel plate composite beam is sealed into the box shoulder pole girder.Certainly, also can adopt other versions.
Suspension hook is suspension hook transformation commonly used on the elevator machinery, promptly removes the lifting hook pulley group, and H-girder is pressed assembly pulley mount pin shaft alignment and perforate, and suspension hook two side plates insert built H beam and are welded into integral body with it.
Wind electric field blower is arranged comparatively and is disperseed; The full ground of large-tonnage hoisting crane is used in the wind electric field blower equipment hoisting in mountain and hill area, high mountain zone and has been occupied leading position, and in the practice of construction process, often can run into required hoister in large tonnage tool again can not rent and have 2 little other elevator machineries of tonnage level maybe can rent on the leasing market but because loop wheel machine tonnage large resource lacks the unaffordable situation of the high construction cost of value of leass relatively in the required time period.
The special hanger for hoisting of present embodiment designs for satisfying above-mentioned blower fan lifting environmental requirement just.Below with the lifting of certain 1MW Fan Equipment with the special hanger design, be applied as example, but the blower fan special hanger for hoisting reference design of different big or small units.
The design calculation of special hanger: this type heaviest piece cabin 41.5t, design special hanger for hoisting as the load of checking.

2) cross section property: Wx=2180cm
3
Edge of a wing thickness t f=15.8mm web thickness tw=10mm
3, correlation parameter
1) material: Q235
2) x axle plasticity development coefficient gamma x:1.05
3) amount of deflection of beam control [v]: L/750
4, inner forces calculation result
1) end reaction RA=RB=243KN
2) end reaction RB=Pd/2=243KN
3) maximal bending moment Mmax=Pd * L/4=369KN.M
5, intensity and rigidity checking result
1) bending normal stresses σ max=Mmax/ (γ x * Wx)=161.2N/mm
2
2) maximum defluxion fmax=Pk * L^3/48 * 1/ (E * I)=3.55mm
3) relative amount of deflection v=fmax/L=1/844.6
Bending normal stresses:
σ max=161.2N/mm
2＜bending Design value f:215N/mm
2
Meet the requirements!
The mid-span deflection relative value:
V=L/844.6＜amount of deflection controlling valu [v]: L/750
