The invention discloses a bridge structure with a built-in hinged end beam. The bridge structure with the built-in hinged end beams comprises two main beams, two auxiliary main beams, two end beams and four end beam hinged shafts, the two main beams are symmetrically arranged, the two end beams are symmetrically arranged between the two main beams through the four end beam hinged shafts respectively, the two auxiliary main beams are symmetrically arranged between the two end beams, and the two auxiliary main beams are symmetrically arranged between the two end beams. According to the bridge structure with the built-in hinged end beams, the end beams are positioned on the inner sides of the fulcrums, so that the limitation of wheel positions of a cart running mechanism and the height of a cart rail surface on the bridge structure is thoroughly eliminated, the overall height of a crane is effectively reduced, and the construction cost of a new plant is effectively reduced.

    本发明公开了一种内置铰接端梁的桥架结构。内置铰接端梁的桥架结构包括两个主梁、两个副主梁、两个端梁和四个端梁铰轴,其中:两个主梁对称设置,两个端梁分别通过四个端梁铰轴对称设置在两个主梁之间,两个副主梁对称设置在两个端梁之间,该内置铰接端梁的桥架结构使端梁位于支点内侧,彻底摆脱大车运行机构车轮位置和大车轨面高度对其的限制,有效降低了起重机的整车高度,从而有效减少新厂房的建设成本。
