摘要
Abstract
The main beam,saddle and leg structure of gantry crane need to be split design,among which the main beam structure needs to be segmented design,and the segment or split place is connected by flange and bolt group.Aiming at the box section structure,the type and strength calculation method of bolt group at the section or split point are introduced,and the influence of structural internal force on the calculation of wing plate bolt group and web bolt group is expounded.By introducing the structure composition and splitting method of gantry crane,the calculation method of wing plate bolt group and web bolt group at the section of main beam is expounded.It is explained that the bending moment of main beam is borne by wing plate and web bolt group,and the influence of bending moment of main beam on web bolt group is analyzed,and the best arrangement scheme of web bolt group is given.The calculation method of the upper and lower flange bolt groups is introduced.It is shown that the bending and stretching action of the flange bolt groups decreases under the action of the leg shaft pressure,and the influence of the shear force and torque of the flange surface on the flange bolt groups cannot be ignored.关键词
