Embodiment Construction
[0026] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0027] Such as Figure 1-2 As shown in the figure, a hoisting beam for steel pipes with flange structure includes an upper plate 1 and a lower plate 2 with arc-shaped left and right ends. There are also three transverse stiffening plates 4 and one longitudinal stiffening plate 5 between the plate 1 and the lower plate 2 of the beam. The top surface of the upper plate 1 of the beam is provided with three left and right symmetrical hoisting parts, and the left and right sides of the beam are symmetrically Each is provided with a flange connecting portion connected to the steel pipe flange 10 .
[0028] In order to realize a firm and reliable hoisting structure, each hoisting part includes a hoisting earhole plate 6 with hoisting earholes 601, and hoisting stiffeners 7 perpendicular to the hoisting earhole plate 6 are provided on both ...

The invention discloses a lifting cross beam for a flange structure type steel pipe, and relates to the field of transmission line steel pipe tower assembly and erection construction. Transmission line steel pipe towers are widely used due to the remarkable structural advantages, conventional lifting appliances have the characteristics such as simple structure and convenient transportation, but the structure of the conventional lifting appliances is prone to being damaged by force, the service life is shorter, and the conventional lifting appliances are prone to being lost during use. The lifting cross beam comprises a cross beam upper plate and a cross beam lower plate, and cross beam outer connecting plates are welded between the left and right ends of the cross beam upper plate and thecross beam upper lower plate. Horizontal stiffening plates and longitudinal stiffening plates are further welded between the cross beam upper plate and the cross beam lower plate, and a plurality of left-right symmetrical lifting portions are welded on the top surface of the cross beam upper plate. Flange connecting portions connected with steel pipe flanges are arranged on the left and right sides of the cross beam. The structural strength of the cross beam is high, the lifting portions are used for hook lifting, the flange connection portions can be connected with the steel pipe flanges, andthe lifting is stable; and compared with the conventional lifting appliances, the overall structural strength of the lifting cross beam is high, and the lifting stability is good.
Description
technical field [0001] The invention relates to the field of erection and construction of steel pipe towers for transmission lines, in particular to a hoisting crossbeam for steel pipes with flange structure. Background technique [0002] With the continuous improvement of the transmission capacity and voltage level of transmission lines, double-circuit and multi-circuit lines on the same tower have been built successively in some economically developed areas and have become a development trend, and the load on towers has also continued to increase. In this case, if angle steel towers are used, the main material of the straight towers is basically two-combination or four-combination angle steel. The amount of steel and construction costs increase, the design, processing, and installation of iron towers become more difficult, and the uncertain factors affecting structural safety increase. [0003] Compared with the angle steel tower, the steel pipe tower has low wind pressur...
