The invention discloses a special-shaped shipbuilding bridge crane girder which comprises a box type girder composed of an upper flange, a connecting slope, an inner web plate, a lower flange and an outer web plate, the upper flange and the lower flange are located at the top and the bottom respectively and arranged in parallel, the width of the upper flange is smaller than that of the lower flange, and the inner web plate and the outer web plate are located on the two sides respectively. The inner web is lower than the outer web, the outer web is vertically connected with the upper flange and the lower flange, the upper flange is connected with the top end of the inner web through a connecting inclined plane, and the inner web is vertical to the lower flange. The device adopts a special-shaped section design, so that the overall height of the hoisting structure can be reduced; longitudinal bars are arranged, the strength of the whole main beam structure is enhanced, and deformation caused by long-time use of the structure is avoided; the partition plates are arranged to enhance the stability of the main beam structure; according to the lifting structure assembled by the device and the upper and lower trolleys, the height of the whole lifting structure is reduced, the height space required by equipment can be reduced, the upper-layer space is reduced, and the investment of an external plant of the lifting structure is saved.
本发明公开了一种异型造船桥式起重机主梁,包括由上翼缘、连接斜面、内腹板、下翼缘、外腹板组成的箱体式主梁,上翼缘、下翼缘分别位于顶部与底部,上翼缘、下翼缘平行设置,上翼缘宽度小于下翼缘,内腹板、外腹板分别位于两侧,内腹板高度低于外腹板,外腹板与上翼缘、下翼缘垂直连接,上翼缘通过连接斜面与内腹板顶端连接,内腹板与下翼缘垂直设置。本装置为异型截面设计,能减小起重结构总体高度;设置纵筋,加强整体主梁结构的强度,避免结构长时间使用产生变形;设置隔板,增强主梁结构的稳定性;本装置与上下小车组装成的起重结构,整体起重结构高度下降,能减少装备需要的高度空间,降低上层空间,节约起重结构外部厂房的投资。
