Three-dimensional elastic support

Abstract

The invention relates to a three-dimensional elastic support. The three-dimensional elastic support comprises a sliding plate, a top seat, a pedestal and a disk spring component, wherein the lower surface of the sliding plate is a smooth plane; the main body of the top seat is inverted cup-shaped; the sliding plate is positioned on a top plate of the top seat; the top plate is connected with a guide column which extends downwards; the main body of the pedestal is cup-shaped; an upper sleeve of the pedestal is cylindrical; the disk spring component sleeves the guide column, the upper end is supported against the top plate, and the lower end is supported against the bottom plate; an upper flange on the upper sleeve and a lower flange on the bottom plate are provided with threaded fastening members. The support has a simple, firm and durable structure and wide applicability; the requirement on free sliding in a three-dimensional space of a supported object can be met while complex change load is born; the supported object is also allowed to rotate around the normal of the supporting surface; the support is particularly suitable for supporting facilities and equipment under complex working conditions such as superimposed changeable load and multi-dimensional deformation.

Description

technical field [0001] The invention relates to a three-dimensional elastic bearing, which can be mainly used in the engineering fields of petrochemical industry, water conservancy and electric power, light industry, textile, road and bridge, etc., and is especially suitable for complex working conditions such as superimposed variable load and multi-dimensional deformation. Support for facilities and equipment. Background technique [0002] At present, for some equipment and facilities with special structures and complicated operating conditions, rigid support will cause excessive local stress in the structure, and the stress state does not meet the requirements of the specification and may easily cause damage to the equipment and facilities. For example, the gas phase pipeline connected to the scraper condenser in the polyester plant has a large size, high temperature, and high rigidity of the system, which will generate large pipeline stress when heated; the vertical and h...

Problems solved by technology

[0002] At present, for some equipment and facilities with special structures and complicated operating conditions, rigid support will cause excessive local stress in the structure, the stress state does not meet the requirements of the code, and it is easy to cause damage to the equipment and facilities

For example, the gas phase pipeline connected to the scraper condenser in the polyester plant has a large size, high temperature, and high rigidity of the system, which will generate large pipeline stress when heated; the vertical and horizontal dimensions of the scraper condenser itself are large , has a certain amount of expansion; the self-weight of the equipment itself and the gravity of the material, as well as the vibration caused by the rotating parts; due to these complex additional loads, thermal expansion, vibration and other factors, the traditional rigid support cannot meet the normal use of the equipment

In order to solve such problems, equipment designers usually adopt two methods: increasing the size of components or increasing the strength level of structural materials. On the one hand, it causes waste of materials, and on the other hand, it cannot fundamentally solve the problem
