The invention provides an auxiliary device for maintenance of a luffing mechanism and a gantry crane, and relates to the field of crane maintenance. The auxiliary device comprises a first sliding rodand a second sliding rod which are hinged to a stand column, wherein the first sliding rod matches with a first trolley moving in the axial direction of the first sliding rod, the first sliding rod horizontally rotates around a vertical line where a hinged point of the first sliding rod and the stand column is located, the second sliding rod is hinged to a balance beam through a connecting rod andused for jointly rotating in a vertical plane under the action of the balance beam, a second trolley moving in the axial direction of the second sliding rod matches with the second sliding rod, and the first trolley and the second trolley are used for cooperatively conveying luffing mechanism parts. The auxiliary device for maintaining the luffing mechanism is arranged on a four-bar linkage balance structure of the crane in advance, during maintaining, the auxiliary device binds and restrains the four-bar linkage balance structure of the crane, a four-bar linkage maintaining crane assembly and a rotary maintaining crane assembly are adopted, lifting lugs do not need to be installed and welded any more, nondestructive construction is achieved, restorative construction is not needed, and the whole maintenance efficiency is improved.

    本公开提供一种用于变幅机构维护保养的辅助装置及门座起重机,涉及起重机维保领域,包括用于铰接在立柱上的第一滑杆和第二滑杆,第一滑杆配合有沿其轴向移动的第一小车,第一滑杆绕其与立柱铰接点所在竖直线水平转动,第二滑杆通过连杆铰接在平衡梁上,用于受平衡梁作用共同在竖直面内转动,第二滑杆上配合有沿其轴向移动的第二小车,第一小车和第二小车用于协同运送变幅机构零部件,通过将变幅机构维护保养用的辅助装置预先布置在起重机四连杆平衡结构上,在进行维护保养时,辅助装置将起重机四连杆平衡结构进行捆绑约束,采用四连杆维护行车组件和旋转维护吊组件,无需再装焊吊耳,无破坏性施工,无需恢复性施工,提高了整个维护保养的效率。
