A heavy-duty truss

Abstract

The invention relates to a heavy-load truss. The heavy-load truss comprises a plurality of bottom beams, a plurality of transverse beams and skin. The bottom beams are in semicircular-ring shapes, openings of the bottom beams are upward, the multiple bottom beams are distributed in the horizontal direction and arranged in parallel, and the circle centers of the semicircular-ring shapes of the multiple bottom beams are located on one horizontal line. The multiple transverse beams are fixedly arranged inside the multiple bottom beams in the horizontal direction and distributed in the circumferential directions of the semicircular-ring shapes. The skin is laid on the transverse beams. The heavy-load truss has the advantages of being large in supporting weight, high in strength and light in weight, and the accuracy guide effect can be improved.

Description

technical field [0001] The invention relates to the field of support frames, in particular to a heavy-duty truss with a high-precision guiding structure. Background technique [0002] The traditional truss products are welded by steel pipes, the structure is relatively simple, and the function is too single, mainly by setting two or more supports in the truss to support the product, and the supported products are fixed relative to the truss, and cannot be moved during the process. It is mainly used in the field of product reprinting. [0003] This traditional truss product cannot meet the use requirements in some special fields, especially in the field of rocket body support technology. Traditional truss products are mainly used for the support of small rocket bodies, and most of the rocket bodies are unfilled. The weight to be supported is light. For larger and heavier rocket bodies, traditional trusses are difficult to meet the needs of use. Under such working condition...

Problems solved by technology

[0005] In order to solve the defects in the prior art that the traditional truss support weight is small, the products to be supported cannot move relative to the truss, and there is no guiding function, a heavy-duty truss of the present invention includes multiple groups of bottom beams, multiple beams and skins, bottom beams It is a semi-circular ring with an opening upward, and multiple sets of bottom beams are distributed along the horizontal direction and arranged in parallel. The centers of the semi-circular rings of multiple sets of bottom beams are on the same horizontal line, and multiple cross beams are fixedly arranged inside the semi-circular rings of multiple sets of bottom beams along the horizontal direction. And distributed along the circumference of the semicircle, the skin is laid on the beam
