Honeycomb crossbeam structure

Abstract

The invention discloses a honeycomb crossbeam structure. The honeycomb crossbeam structure comprises a crossbeam frame; a plurality of reinforcing rib plates are arranged in the crossbeam frame; connecting plates are arranged between adjacent reinforcing rib plates and between the adjacent reinforcing rib plates and the crossbeam frame; the reinforcing rib plates are connected into a whole through the connecting plates. The bending deformation of the crossbeam is greatly reduced under the conditions of the same materials, the same sectional area and the equal stress, so that the cross sectional area is reduced in the same deformation tolerance range, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to a honeycomb beam structure, which is suitable for heavy-duty long-span gantry beams. Background technique [0002] Under the current technical conditions, the design and manufacture of long-span heavy-duty gantry milling beams is mainly to reduce the beam deformation caused by gravity and load as the main research direction. The design concept of disc reinforcement and large cross-section machine is mostly used to achieve high strength and high stability of the beam, thereby reducing deformation. The larger the cross-sectional area of ​​the beam, the better its bending resistance, tensile strength, and stability. However, if the cross-sectional area is too large, the weight of the beam will be too heavy, which will increase the deformation of the beam. [0003] In order to overcome the deformation of the beam, it is generally adopted to add reinforcing ribs to the cross-section of the beam. The traditional reinforcement genera...

Problems solved by technology

Its disadvantage is that to ensure its own rigidity, it needs to increase the cross-sectional area and the height and thickness of the rib plate
