Further, as shown in Figure 3, two outward flanges 2 are bilateral V-type weld seam with the weld seam of cylindrical shell 1.This place's weld seam is bilateral V-type weld seam, and for ensureing that outward flange 2 is in the time welding, these weld seam both sides are all heated simultaneously, thereby prevent welding deformation, further ensure that steel rope 5 there will not be the problem such as disorder cable or rope skipping in the time being wound on cylindrical shell 1.
Further, as illustrated in fig. 1 and 2, two inside flanges 3 are monolateral V-type weld seam with the weld seam of cylindrical shell 1, and the opening direction of the groove of monolateral V-type weld seam is the center arrangement of cylindrical shell 1 dorsad.The welding towards making two inside flanges 3 and cylindrical shell 1 of this groove can be carried out in the outside of cylindrical shell 1, thereby avoid operator need to pierce that cylindrical shell 1 is interior carries out welding operation to the weld seam of inside flange 3, in the time that the diameter D of cylindrical shell 1 is less than 1.5m, the sight line of cylindrical shell 1 inside is poor, and then cannot ensure the welding quality of this place's weld seam, can fully ensure the molten property of weld seam and avoid weld defect in the welding of the outside of cylindrical shell 1, thus the quality of guarantee weld seam.
Particularly, weld packing ring 1a on the inwall of cylindrical shell 1, packing ring 1a is arranged on the sidewall that two inside flanges 3 are relative.This packing ring 1a can coordinate the monolateral V-shaped weld of interior side flange 3 to use, and the thickness of packing ring 1a is 4-8mm, and packing ring 1a is the circular ring type structure of pottery or steel material.Wherein, this packing ring 1a can put on the inwall that is welded in cylindrical shell 1 or on the sidewall of inside flange 3.
Particularly, as shown in Figure 2, the angle [alpha] of this groove is 30-40 °, and the height h1 of the leg of weld seam is 4mm～8mm.
Particularly, the end face at the two ends of cylindrical shell 1 is concordant with the sidewall of two outward flanges 2.
Particularly, the difference in internal diameters of the internal diameter of cylindrical shell 1 and inside flange 3 is 30-50mm.
In conjunction with above-mentioned embodiment, the present embodiment provides another kind of implementation, as shown in Figure 4, is provided with two without grooving district 4b on the outer wall at the two ends of cylindrical shell 1, equal the footpath, the end of grooving 4a without the external diameter of cylindrical shell 1 corresponding to grooving district 4b, outward flange 2 is positioned at the 4b without grooving district.
Further, without the width Ls of grooving district 4b be arranged on the steel rope 5 on grooving 4a diameter d s 0.6-1.2 doubly, and be π × D without the length of grooving district 4b
o, D
0for the footpath, the end of grooving 4a.
Particularly, grooving 4a is for lay winding wire ropes 5, as shown in Figure 4, cylindrical shell 1 revolves and turns around, grooving 4a is grooving pitch P of upper feeding in the horizontal direction, a from Fig. 4 is the grooving 4a of a whole circle to b place, and the grooving 4a of the whole circle indicating taking right shade part is as example, and the width of this dash area is that grooving 4a diameter p, length are π × D
o, oblique angle is the slightly-inclined shape region of δ (tan δ=p/ π D).
As shown in Figure 1 and Figure 4, this can provide certain operational space for welding two relative sidewalls of outward flange 2 without grooving district 4b, wherein, is Ls without the width of grooving district 4b, and length is also π × D
oin the time processing without grooving district 4b, first on cylindrical shell 1, process grooving 4a, on grooving 4a, process again without grooving district 4b, now, grooving 4a and have in the horizontal direction lap without grooving district 4b, this lap need to be processed into the 4b without grooving district with turnning and milling, provides certain operational space without the weld joint on inner side welding operation that exists for outer flange 2 of grooving district 4b.
Further, without being provided with rope climbing piece (not shown) or wedge shape filling block (not shown) on grooving district 4b, rope climbing piece or wedge shape filling block are positioned on the sidewall that two outward flanges 2 are relative.In the time that the steel rope 5 on cylindrical shell 1 is wound around more than 2 layers or 2 layers, on without grooving district 4b, rope climbing piece or wedge shape filling block are installed, rope climbing piece and wedge shape filling block can enclose to next for rope hoisting.
Cylinder is important stressed member, its weld seam need to carry out 100% ultrasonic flaw detection, as Fig. 1, Fig. 2, shown in Fig. 3 and Fig. 4, hypracoustic probe detects inside flange 3 and outward flange 2 respectively, can reach by adjusting the internal diameter size of inside flange 3 requirement that flaw detection is adjusted the distance, the external diameter of outward flange 2 is to the outermost distance >=2.5ds of steel rope 5, wherein ds is the diameter of steel rope 5, can reach by adjusting the external diameter of outward flange 2 requirement that flaw detection is adjusted the distance, and the weld seam form of inside flange 3 and outward flange 2 is easy to welding operation and carries out ultrasonic flaw detection, weld seam by 100% ultrasonic flaw detection after the assay was approved, the bulk strength of cylinder is effectively guaranteed.
The utility model embodiment is by welding the outer wall at the inwall of two outward flanges and cylindrical shell two ends, the inwall welding at the outer wall of two inside flanges and cylindrical shell two ends, thereby the weld seam between outward flange and inside flange and cylindrical shell is become to horizontal direction, and then avoid weld seam can bear the intensity that affects weld seam compared with large shearing stress, in addition, outward flange and inside flange adopt respectively bilateral V-type weld seam and monolateral V-type weld seam to weld, thereby ensure the welding quality of weld seam.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
