The invention discloses an oval main beam structure device of a bridge crane. The oval main beam structure device comprises a lower circular plate and an upper cover plate which are welded through a front-rear end web, right-angle mounting notches are formed between included angles between the left end face and the right end face of the upper portion of the web and the upper cover plate, the leftend face and the right end face of the lower portion of the web and a lower circular plate are inverted-trapezoid-shaped circular bead plates; a connecting plate is welded and fixed to the end faces of the right-angle mounting notch beams, a fixing mounting hole is formed in the attaching face of the connecting plate; inner upper and lower semicircular plate reinforcing ribs, two side end face reinforcing ribs and web reinforcing ribs are welded between a horizontal frame plate and an upper cover plate, wherein the horizontal frame plate is installed on the web up and down; limiting plates arearranged at the left and right ends of the upper cover plate; and a trolley track is welded at the top end of the center. The oval main beam structure device of the bridge crane reduces the self weight of the crane, reduces the installation height, is more concentrated and stable in acting force, less in welding, high in strength, not prone to dust accumulation and water storage, higher in practical performance, reasonable in design, simple in overall structure and suitable for wide popularization.

    本发明公开了一种桥式起重机椭圆形主梁结构装置,包括由前后端腹板焊接的下圆板及上盖板;所述的腹板上方左右两端面与上盖板夹角之间设置有直角安装槽口,所述的腹板下方左右端面与下圆板设置为倒梯形圆角板;所述的直角安装槽口梁端面处焊接固定有连接板,其连接板贴合面上设置有固定安装孔;所述的腹板上下安装的水平框架板与上盖板之间焊接有内上下半圆板加强筋,两侧端面加强筋及腹板加强筋;所述的上盖板左右端设置有限位板,其中央顶端焊接有小车轨道;本发明桥式起重机椭圆形主梁结构装置减少起重的自身重量,降低安装高度,作用力更加集中稳定,焊接少强度高,不易积灰存水,实用性能更高,其设计合理,整体结构简单,适合广泛推广。
