In down-comer axial direction, paired arc is respectively welded in shackle plate both ends, and shackle plate is provided with lifting hole(eyelet).
Further, the angle at the downside both ends of the stiffener, and the angle at the downside both ends of shackle plate, point
Not Ju You chamfering, osculum is formed at chamfering.
Further, it is 90~160 ° that the arc, which fans annular central angle, the spacing of the arc in pairs for 500~
800mm。
Further, two pieces of parallel shackle plates are provided between the paired stiffener, the shackle plate is set
It is equipped with two lifting hole(eyelet)s；The stiffener and shackle plate are rectangular slab.
The beneficial effects of the utility model are：The shackle structure of above-mentioned blast furnace down-comer, can be more balanced share lifting
Stress, shearing force suffered by reduction tube wall, by the shackle structure, can directly be lifted, without the reinforcement of weld in down-comer
Part, after the completion of lifting, shackle structure can be permanently kept in pipeline periphery, save dismantlement work, cost-saved, reduce construction
Risk.
Brief description of the drawings
Fig. 1 is shackle structure schematic top plan view of the present utility model；
Fig. 2 is shackle structure left view schematic diagram of the present utility model；
Reference is in figure：Down-comer 1, arc 2, stiffener 3, shackle plate 4, lifting hole(eyelet) 41.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples：
The shackle structure of blast furnace down-comer, including down-comer 1, the side face of down-comer 1 are welded with a pair of parallel arcs
Plate 2, the arc 2 is the fan annular being adapted to the side face of down-comer 1, and fans the plane of annular perpendicular to 1 axial cloth of down-comer
Office, the central angle that the arc 2 fans annular are 80~180 °；
Paired stiffener 3 is provided between the paired arc 2, the downside of stiffener 3 is welded on down-comer 1 week
Face, and, paired arc 2 is respectively welded in the both ends of stiffener 3 parallel to down-comer 1 axially；
Shackle plate 4 is additionally provided between paired stiffener 3, the downside of shackle plate 4 is welded on the side face of down-comer 1, and
Parallel to down-comer 1 axially, paired arc 2 is respectively welded in the both ends of shackle plate 4, and shackle plate 4 is provided with lifting hole(eyelet) 41.
This shackle structure, it is that arc 2, stiffener 3 and shackle plate 4, dispersible lifting are set in the outer peripheral face of down-comer 1
When stress, reduce tube wall suffered by shearing force, avoid piping failure, therefore can directly be lifted by shackle structure, no
Used in pipeline interior welds reinforcer.
Specifically, as shown in Figure 1, 2, shackle structure includes a pair of parallel arc 2, is welded on the side face of down-comer 1.Arc
Shape plate 2 fans annular, and internal diameter size is adapted to the side face external diameter of down-comer 1, and fans annular place plane perpendicular to the axial direction of down-comer 1.
As shown in Fig. 2 the inner arc end of arc 2 and the side face full weld of down-comer 1.
As shown in figure 1, paired stiffener 3, between paired arc 2, the downside of stiffener 3 and down-comer 1 are full
Weldering, the both ends of stiffener 3 respectively with the full weld of arc 2.
For shackle plate 4 between paired stiffener 3, shackle plate 4 is equally downside and the full weld of down-comer 1, and both ends are distinguished
With the full weld of arc 2.
Shackle plate 4 is provided with lifting hole(eyelet) 41 and connected for Current Collector Sleave, above-mentioned arc 2, stiffener 3, shackle plate 4 and pipeline
Weld simultaneously, stress during lifting can be shared, shearing force suffered by reduction tube wall, prevent from destroying.
According to the size of down-comer 1, the central angle that arc 2 fans annular under normal circumstances is 80~180 °, shackle structure institute
Suitable thickness is selected with steel plate, you can meets lifting requirements.Down-comer 1 can be lifted directly, be reinforced without being set in pipeline
Part, after rigging out, shackle structure does not have to remove, and escapable cost, reduces operating risk.
Shackle structure of the present utility model, it can preferably use the identical steel manufacture of down-comer.It is furthermore preferred that size can be with
It is that arc 2 fans annular central angle as 90~160 °, the spacing of the arc 2 in pairs is 500~800mm.
According to circumstances, can be the stiffener 3 downside both ends angle, and the downside both ends of shackle plate 4
Angle, respectively with chamfering, osculum is formed at chamfering.
Such as stiffener 3 is rectangular slab, then the right angle of its underpart two carries out chamfered, is on the one hand easy to welding, separately
On the one hand osculum can be used as, avoids rainwater from accumulating for a long time between the plate of shackle structure.Similarly, shackle plate 4 can also be
For rectangular slab, chamfering can also be set into osculum.
The quantity of shackle plate 4 can also be selected according to circumstances, can be preferably to set two pieces of parallel shackle plates 4, be hung
Otic placode 4 can set one or two lifting hole(eyelet) 41, be easy to connect.
