A self-adaptive compressive support device

Abstract

The present invention relates to the technical field of pressure support devices, in particular to an adaptive anti-pressure support device, which includes two backing plates and a support column, the support column includes a main column, and the upper end of the main column is provided with A pressure-bearing ring, an elastic backing ring is provided between the main cylinder and the pressure-bearing ring; the upper end surface of the pressure-bearing ring is provided with a chute extending along its radial direction, and the chute A sliding bar is installed in the middle slide, one end of the sliding bar protrudes from the pressure bearing ring, and the other end extends into the inner hole of the pressure bearing ring, and the upper end surface of the sliding bar is slidingly matched with the upper backing plate; The main cylinder is provided with a driving block that extends into the inner hole of the pressure bearing ring, and the driving block is in the shape of a cone with a small upper part and a larger lower part; the slide bar extends into the inner hole of the pressure bearing ring One end is in driving contact with the side wall of the driving block. The pressure-bearing surface of the invention can be self-adaptively expanded and dispersed, avoiding excessive concentration of the pressure-bearing surface, making the support more stable, and the structure is not easy to be damaged.

Description

technical field [0001] The present invention relates to the technical field of pressure support devices, and in particular, to an adaptive pressure resistance support device. Background technique [0002] In the fields of construction and industry, the support and storage of various components, equipment, raw materials and even transfer vehicles are relatively common. For the above-mentioned support occasions, the usual practice is to use supports for support, for example, a support frame made of steel welding At present, there is a type of support, which is composed of two upper and lower backing plates and several support columns distributed in the middle. It is mainly used for gravity support in occasions where the storage area is small and the space gas circulation is required to be high. It has strong pressure capacity, wide range of upper and lower pressure bearing, and strong practicability, so it is used in many fields, but the pressure bearing surface of the support...
