The specific embodiment

Below in conjunction with embodiment and accompanying drawing thereof, the utility model is illustrated further.

Embodiment 1

In sky, Tianjin pipe Taiyuan Iron and Steel Co. ERW welded tube projects, be this condition of 32t according to two overhead traveling crane biggest lifting capacities in factory building, two length of linking up with while driving a vehicle side by side are between 9 meters-10 meters, for meeting 2 overhead traveling crane work compounds, need realize by a special carrying pole type beam handling and the installation of equipment, considering the weight of self, is 60 tons according to maximum weight-lifting equipment weight, selects 2 H section steel manufactures of HM588*300*12*20 to become the double row flat spreader beam.

Now refer to Fig. 1 and Fig. 2, the hanger structure schematic diagram that Fig. 1 is the utility model embodiment, the cutaway view that Fig. 2 is A-A in Fig. 1.As shown in the figure, described two H shaped steel 1 are and are arranged in parallel, be provided with two roads between two H shaped steel and be connected and fixed plate, the 1st be connected and fixed plate 4 and the 2nd and be connected and fixed plate 5, two road connecting panels all adopt the 20mm steel plate, and two H shaped steel center-to-center distances are 1 meter, and stiffener 6 adopts the 20mm steel plate to arrange at interval of 300mm, be made into the double row flat spreader beam, the specifications and models of described H shaped steel are HM588*300*12*20;

Described two shackle plates are two block plates, i.e. the 1st shackle plate 2 and the 2nd shackle plate 3, the space certain distance is and is arranged in parallel, the rectangular shape of every block plate, shackle plate adopts the thick steel plate of 40mm, and is provided with a hanger circular arc 7 on its long limit, the radius of hanger circular arc is 600mm, be provided with hanger hole 8 below hanger circular arc 7, the radius in hanger hole is 250mm, in the left and right sides in hanger hole, according to the distance of H shaped steel is parallel, has two holes;

Wherein: described two shaped steel are through complete suspender of two hole formations of below, two shackle plate hanger holes.Described shackle plate can move freely setting on H shaped steel 1, and the fixed form between shackle plate and H shaped steel is inclined sizing block.Edges and corners, described shaped steel upper and lower flange plate edge are welded and fixed the steel pipe of half sheet DN40, the stressed wearing and tearing of steel rope while preventing from lifting by crane.

Force analysis for the suspender that lifts ERW equipment of the present utility model:

The force analysis schematic diagram of the suspender that Fig. 3 is the utility model embodiment.According to the maximum deadweight of equipment, 60t calculates, and according to on-site actual situations, need be lifted with the double row flat spreader beam, and four suspension centres are set, because shoulder pole girder is welded as a whole, twin beams is checked and can be reduced to the single-beam check, and force analysis as shown in Figure 3.

According to the needs of engineering reality, the maximum defluxion of beam and hard-over are no more than a certain specified value.The rigidity condition of beam is thus:

|y| _max≤[y]

|θ| _max≤[θ]

Figure 3 shows that a crane girder, 10 meter two suspension centre spacing of span length is 9 meters, biggest lifting capacity F _w=300KN, beam is the I-beam section cross section, permissible stress [σ]=140MPa(is according to using the steel plate model), the license amount of deflection

elastic modulus E=200GP _a(according to using the steel plate model to check in).

The selecting and checking of material

Select 2 H shaped steel of 588*300*12*20, when hoisting heavy, during at suspender mid point C, the C cross section will produce maximal bending moment and maximum defluxion.Maximal bending moment is

${\left(M_{\max }\right)}_W=\frac{1}{4}{F}_{W}l:=675\mathrm{kN}.m$

According to strength condition, obtain

$W_z\≥\frac{{\left(M_{\max }\right)}_W}{\left[\mathrm{\σ}\right]}=482{\mathrm{cm}}^3$

Table look-up this H shaped steel cross section property, W _z=600.52 cm ³, I _z=113283cm ⁴.

Rigidity is checked

$\left[y\right]=\frac{F_W{l}^3}{48{\mathrm{EI}}_z}$ Obtain it [y]=20mm $\left[y\right]=\frac{l}{400}=\frac{10000}{400}\mathrm{mm}=25\mathrm{mm}$ |y| _max＜[y]

Therefore meet the demands.

The stressed sketch of the shackle plate of the suspender that Fig. 4 is the utility model embodiment.When hanger bears maximum load, by Fig. 3 and Fig. 4, can be found out, main strength weak point position b, a, a place, if this three place meets requirement of strength, other positions are no problem.

Known: Fmax=30T

Yield strength: σ s=235N/ ㎜ 2 (thickness of slab is greater than 16mm<=40mm)

Tensile strength: σ b=205N/ ㎜ 2 (thickness of slab is greater than 16mm<=40mm)

At first check a district:

A0=Fmax/σs=30T/235N/㎜2=1276㎜2

Steel plate thickness δ=40mm

a‘=A0/δ=1276/40mm=32mm

Safety factor is made as 1.25

A>=1.25a ', a, a place meets requirement of strength; On-the-spot processing a gets 150mm

B district strength check, be pulling force because it is stressed, and whole steel plate bears shearing, so select: tensile strength: σ b=205N/ ㎜ 2 (thickness of slab is greater than 16mm<=40mm) is checked:

Tmax=2Fmax=60T

σb=Tmax/A0

Ab=Tmax/σb=60T/205N/㎜2=2967㎜2

Steel plate thickness δ=40mm

b’=Ab/δ=2967㎜2/40mm=73mm

Safety factor is made as 1.25

If b>=1.25b ', the b place meets requirement of strength; This beam b is in to add and gets 200mm man-hour

Illustrate: in general check process, as without specific (special) requirements (essential environmental factors as strong wind, at a high speed), safety factor can not got.

Meet construction requirement through calculating and adjusting this suspender.

ERW welded tube engineering of constructing at sky, Tianjin pipe Taiyuan Iron and Steel Co. for the suspender that lifts ERW equipment of the present utility model is used, stability, the reliability of on-the-spot actual verification suspender, effect is remarkable, can not only be applied in the ERW Welded Pipe Plant and carry out equipment hoisting, and also can apply in corresponding equipment installation project, for saving cost, improve work efficiency and crudy and all have very important significance.

Above embodiment is only for illustration of the utility model, but not, to restriction of the present utility model, person skilled in the relevant technique, in the situation that do not break away from spirit and scope of the present utility model, can also make various conversion or variation.Therefore, all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
