The invention provides a beam structure of a quay crane, the quay crane and an assembly method of the beam structure. The girder is arranged opposite to the cross beam in the height direction of the beam structure, the interior of the girder is hollow to form a first cavity, the side, facing the cross beam, of the girder is provided with a girder panel, the girder panel is provided with a top face facing the cross beam and a bottom face deviating from the cross beam, and the girder panel is provided with an insertion opening communicated with the first cavity; a first part of the side connecting plate extends into the first cavity through the insertion port so as to be respectively connected with the cavity bottom of the first cavity and the bottom surface of the girder panel in a welding manner; and the second part of the side connecting plate extends out of the girder from the insertion port so as to be respectively welded on the top surfaces of the cross beam and the girder panel. In this way, the load is directly conducted to the girder bottom plate from the side connecting plates and passes through the girder panel, so that the girder panel, the first welding seam and the second welding seam are prevented from being affected by load conduction, the fatigue performance of a welding area on the girder panel is improved, and the service life of the quay crane is guaranteed.
本发明提供了一种岸桥的梁结构、岸桥及梁结构的装配方法,其中,梁结构包括:横梁;沿梁结构的高度方向与横梁相对设置的大梁,大梁内部中空形成第一腔体,大梁朝向横梁的一侧为大梁面板,大梁面板具有朝向横梁的顶面和背离横梁的底面,大梁面板设置连通第一腔体的插接口;侧连接板,侧连接板的第一部分由插接口伸入至第一腔体内,以分别焊接相连第一腔体的腔底和大梁面板底面;侧连接板的第二部分由插接口伸出至大梁外,以分别焊接相连于横梁和大梁面板顶面。这样载荷直接由侧连接板传导至大梁底板,而经过大梁面板,以避免大梁面板、第一焊缝和第二焊缝受载荷传导的影响,进而提高大梁面板上焊接区域的疲劳性能,以保证岸桥的使用寿命。
