Abstract

The invention provides a shear-stress-resisting flange butt joint device. The device comprises a flange plate I, a flange plate II, bolt fasteners, a safety device, a connecting body and a connecting body. The flange plate I and the flange plate II are square plates in shape. Opening grooves are formed in the lower middle portions of the flange plate I and the flange plate II. A transversely-through groove is formed in the middle of the butt joint face of the flange plate I and the flange plate II. The height of the groove is consistent with the height of the flange plate II. The depth of the groove is consistent with the thickness of the flange plate II. The groove is in clearance fit with the flange plate II. Bolt connecting holes are formed in the peripheral edges of the flange plate I and the flange plate II. The flange plate I is welded to the end face of the corresponding connecting body, and the flange plate II is welded to the end face of the corresponding connecting body. The flange plate II is embedded in the groove in the flange plate I and is fastened through the bolt fasteners, and the connecting bodies are in butt joint. After the flange connecting structure of the shear-stress-resisting flange butt joint device is adopted, the connecting face is allowed to bear large shear force, bolts are protected, and the connecting reliability is improved.

Description

technical field [0001] The invention belongs to the technical field of launch vehicles or missile ground transport and launch devices, and in particular relates to a shear stress-resistant flange butt joint device. Background technique [0002] Flange connection is a commonly used mechanical connection method, mainly through a pair of flange faces and its upper bolt holes and bolt fasteners to fasten the two parts together, which is convenient for installation and disassembly. Generally speaking, in the flange design, in order to ensure the strength of the bolts and the reliability of the connection structure, it is required to ensure that the bolts only bear axial pressure or tension and less shear force. member. For components that need to bear larger scissors on the connecting surface and require easy disassembly, the existing products at home and abroad are less used. The inventive scheme proposed in this paper is just to solve this problem. Contents of the invention...
