Three-level buffer working method suitable for adjusting all levels of buffering sequences

Abstract

The invention relates to a three-level buffer working method. A three-level buffer is composed of a leading-level buffer, a middle-level buffer and a tail-level buffer. The leading-level buffer, the middle-level buffer and the tail-level buffer respectively comprise a cylinder which is in the shape of a column. Each cylinder is filled with buffering media. A cylinder cover is arranged at the opened end of the cylinder and seals an opening. A center through hole which extends axially is formed at the central axis of the cylinder cover. A piston rod penetrates through the center through hole and a piston body assembly is arranged at the top end of the piston rod, suitable for carrying out piston motion in the cylinder and matched with the inner wall of the cylinder in a movable and sealed mode. The cylinder of the leading-level buffer forms a piston rod of the middle-level buffer. The cylinder body of the middle-level buffer forms a piston rod of the tail-level buffer. A pressure sensor for detecting pressure of the media is arranged on the right end face of the piston body assembly of the leading-level buffer. When the piston body assemblies of all levels of the buffers perform piston motion, media reciprocating flow in corresponding cylinders is adjusted according to the media pressure detected by the pressure sensor so as to control speed of the piston motion.

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,...
