Working method of two-stage buffer suitable for adjusting buffer sequences of all stages

Abstract

The invention relates to a working method of a two-stage buffer. The two-stage buffer comprises a first stage buffer and a last stage buffer, wherein the first stage buffer comprises a cylinder body and the last stage buffer comprises a cylinder body; the cylinder bodies are cylindrical and used for accommodating buffer media; cylinder covers are arranged at opening ends of the cylinder bodies with openings sealed; central through holes extending axially are formed in positions of central axes of the cylinder covers; and a piston rod penetrates through each central through hole, and a piston body component is arranged at the top of the piston rod, is suitable for performing piston motion in each cylinder body, and is in movable sealing fit with the inner wall of each cylinder body; a cylinder body of the first stage buffer forms a piston rod of the last stage buffer; a pressure sensor used for detecting medium pressure is arranged on the right end surface of a piston body component of the first stage buffer; and piston body components of both the first stage buffer and the last stage buffer are used for adjusting back and forth flows of media in corresponding cylinder bodies according to the medium pressure detected by the pressure sensor during piston motion so as to control the piston motion speed.

Description

technical field [0001] The invention relates to a working method of a buffer, in particular to a working method of a buffer using elastic colloid as a buffering medium. Background technique [0002] In the field of cushioning and shock absorption, buffers are widely used, and their main functions are to absorb various impact energy, protect equipment and reduce noise. [0003] The authorization number CN 202149175 discloses a buffer, which is a two-stage buffer, through the difference of the medium maximum force F1max and the initial minimum force F2cmin in the primary buffer and the secondary buffer, to control the primary buffer, secondary buffer The order of action of the first-stage buffer; and it is mentioned in the specification that the capacity of the entire buffer is set according to the impact energy, but in real work, because the impact energy is not constant, there may be changes, so it depends on the medium To realize the working order of buffers at all levels,...
