The invention provides an auxiliary pull rod of a front girder of a quay crane, which is applied to the quay crane. The quay crane comprises a main frame structure, a front girder and a main pull rod, the front girder and the main pull rod are both connected with the main frame structure, the main pull rod comprises a first pull rod and a second pull rod, one end of the first pull rod and one end of the second pull rod are connected with the main frame structure, and the other end of the first pull rod and the other end of the second pull rod are both connected with the front girder. The auxiliary pull rod comprises a first rod piece and a second rod piece, wherein the first end of the first rod piece is hinged to the front crossbeam; the first end of the connecting piece is hinged to the second end of the first rod piece; the first end of the second rod piece is hinged to the second end of the connecting piece, and the second end of the second rod piece is hinged to the middle of the second pull rod. The foldable auxiliary pull rod is arranged between the front girder and the second pull rod, bounce of the main pull rod and shaking of the front girder are reduced during box grabbing and releasing operation of the trolley, the vertical rigidity of the front girder is improved, and the stability and reliability of quay crane operation are improved.

    本发明提供一种岸桥前大梁的辅助拉杆,应用于岸桥上。岸桥包括主架结构、前大梁和主拉杆,前大梁与主拉杆均与主架结构连接,主拉杆包括第一拉杆和第二拉杆,第一拉杆的一端与第二拉杆的一端和主架结构连接,第一拉杆的另一端和第二拉杆的另一端均与前大梁连接,辅助拉杆包括:第一杆件,第一杆件的第一端与前大梁铰接;连接件,连接件的第一端与第一杆件的第二端铰接;第二杆件,第二杆件的第一端与连接件的第二端铰接,第二杆件的第二端与第二拉杆的中间部位铰接。本发明通过在前大梁和第二拉杆之间设置可折叠的辅助拉杆,在小车抓放箱作业时减少了主拉杆的弹跳和前大梁晃动,提高了前大梁垂向刚度,有助于提升岸桥作业时的平稳性和可靠性。
