A high-strength support plate

Abstract

The invention discloses a high-strength support disc, which comprises a support seat and a support shaft, wherein the support seat comprises a bottom plate, two transverse reinforcing rib plates, two longitudinal reinforcing rib plates, four diagonal reinforcing rib plates, two large cover plates, two small cover plates and an upper cover plate, wherein the support shaft is vertically fixed at the middle part of the upper side surface of the bottom plate; the two transverse reinforcing rib plates, the two longitudinal reinforcing rib plates and the four diagonal reinforcing rib plates are distributed on the periphery of the support shaft in the transverse and longitudinal directions and along the diagonal line, and are welded and fixed with the bottom plate and the support shaft; the upper cover plate sleeves the outer side of the support shaft through a round hole formed in the center and is welded and fixed; the two large cover plates and the two small cover plates are welded and fixed with the bottom plate, the upper cover plate and the adjacent diagonal reinforcing rib plates; the upper end surface of the support shaft is provided with a round groove along the axle line; and the groove bottom of the round groove is further provided with a spherical groove. The high-strength support disc has the advantages that the deformation cannot easily occur; the strength is high; the stress is strong; and the born stress can be uniformly distributed on the ground, so that the support force is improved.

Description

technical field [0001] The invention relates to a support device, in particular to a support plate with high strength and dustproof function. Background technique [0002] The support plate is a commonly used part of equipment such as cranes and support platforms, and its performance directly determines the stability and use effect of the support. Especially for special fields such as launch platforms of launch vehicles, the support plate is required to have the characteristics of large support force and low pressure to meet the requirements of special use conditions, which puts forward higher requirements for the strength and self-weight of the support plate. For example, for some types of launch vehicles, the launch platform is designed with 4 outriggers, and each leg is connected to a support plate to be supported from the ground. Not only the support force of the support plate is required to be as large as 60t, but also The pressure of the disk to the ground should be e...
