Specific implementation mode
The utility model is described in detail below in conjunction with the accompanying drawings.
A kind of heat exchanger integral hoisting tooling, including heat exchanger tube body 1, lifting lug 2, peripheral frame 3 and crane 4, it is described
1 end set flange 5 of tube body, is equipped with four groups of lifting lugs 2 on 5 end face of flange, and each lifting lug 2 is connected to 5 end face of flange by connector 6
On, the heat exchanger is located in frame 3, and crane 4 is equipped in 3 outside side of frame；
The crane 4 is equipped with arm bar 7；
The heat exchanger tube body is equipped with tube bank bearing；
Four groups of lifting lugs 2 are on 5 end face of flange, and centered on the flange center of circle, 4 lines are square；
The lifting lug 2 includes rectangle bottom plate 8, two bolts hole 9 is uniformly provided on bottom plate 8, in the long side of bottom plate 8
It is correspondingly provided with a triangle joint beam 10 respectively, the position between the bolt hole 9 of two, 8 center of bottom plate is equipped with intermediate beam 11, in
Between set that there are one be tied hole 12 on beam 11；
The length of the triangle joint beam 10 is less than the length of bottom plate 8, and the height of triangle joint beam 10 is less than intermediate beam
11 height；
On-site hoisting operation specific embodiment：
A, lifting lug 2 is installed:Upper flange 5 is restrained on E2403,4 groups of prefabricated lifting lugs is uniformly installed, each lifting lug is with 2 groups
8.8 grades of high-strength bolts connection fastening of M36 × 240, amounts to 8 groups；
B, crane is in place:100 tons of truck cranes press designated position erect-position, and 7 rotation of arm bar fastens rope to 2 top of E2403 lifting lugs
Hook, and rigging is tightened to 10 or so of lifting strength in advance, determine that hoisting rig and crane run rope without deflection；
C, rope examination is played to hang:Crane plays rope, and E2403 tube banks are vertically sling, and tube bank bearing is made to be higher by basis top plane 300mm
Afterwards, stop lifting, check that Lift-on/Lift-off System includes each position stressing conditions such as crane, erect-position point, lifting lug, rigging, if any exception, stand
It will restrain to put down and be handled；
D, after errorless on inspection, traction crane slowly plays rope, when restraining bearing and being promoted under upper cover platform, stopping
It is promoted, tube bank is rotated into 45 degree of angles, tube bank bearing is enable to pass through from the space after upper brace cutting；Commander's crane hangs tube bank
It after rising, lies on the vacant lot of ground, tube bank lower part is good with tie plate in advance；The performance parameter value of the lifting lug is calculated：Lifting lug is drawn
Stress calculation
σ=P/A=monaurals lift heavy/＜ (shackle plate wide-lifting lug aperture) × lifting lug plate thickness ＞
=(22/4 × 103Kgf)/<(10cm-5cm)×2cm>
=0.55 × 103Kgf/cm2 is less than [σ]=1.6 × 103Kgf/cm2
Therefore lifting requirements can be met；
Lifting lug Calculation Shear
Shear stress τ=P/A
=monaural lift heavy/＜ (shackle plate circular arc outer diameter-lifting lug hole outer diameter) lifting lug plate thickness ＞
=(22/4 × 103Kgf)/<(14.5cm-8.5cm-2.5cm)×2cm>
=0.785 × 103Kgf/cm2 is less than [τ]=0.98 × 103Kgf/cm2
Therefore lifting requirements can be met
High-strength bolt is calculated
The path of M36 high-strength bolts (grade 8.8) Nominal Tensile 800MPa, M36 bolt is 30mm；Its maximum fracture
T=800MPa*3.14*30^2/4=565200N=56.5 tons of pulling force；Hoisting Security COEFFICIENT K selects 5, therefore the high-strength spiral shells of single M36
The safe pulling force of bolt is 11.3 tons, and the safe pulling force of 8 high-strength bolts is 90.4 tons, and significantly larger than 22 tons of lifting is heavy, because
This calculates safety；
Safe wire cable is calculated
Steel wire rope selects Φ 32, rupture pull force 380KN, fracture safety coefficient to select 5, therefore the safe pulling force of single wire rope
It is 76KN=7.75 tons；
It is 31 tons that E403 liftings, which use 4 32 steel wire ropes of Φ, safe pulling force, is more than 22 tons of lift heavy；Crane lifting ability is selected
With accounting
E403 is restrained：G=22t, 100t truck crane：Go out pole length=36.9m；Operating radius=12m；Crane rated load
For Q volumes=23.5t
Q volume ＞ P, therefore safety is checked, crane meets Lifting Capacity.
