Two-level buffer suitable for controlling buffering sequence step by step

Abstract

The invention relates to a two-level buffer suitable for controlling a buffering sequence step by step. The two-level buffer comprises a first-level buffer and a last-level buffer, and is characterized in that each buffer comprises a cylindrical cylinder, wherein a cylinder cover is arranged at the opening end of the cylinder in a sealing manner, a piston rod is movably matched with a through hole of the cylinder cover in a sealing manner, and a piston body component is arranged at the right end of the piston rod, suitable for performing piston motion in the cylinder and movably matched with the inner wall of the cylinder in a sealing manner; the cylinder of the first-level buffer forms the piston rod of the last-level buffer; a pressure sensor used for detecting medium pressure is arranged on the right end surface of the piston body component of each of the first-level buffer and the last-level buffer; and the piston body component of each buffer is suitable for adjusting a medium back-and-forth flow of the corresponding cylinder according to the medium pressure detected by each pressure sensor during piston motion, so that the piston motion speed can be controlled.

Description

technical field [0001] The invention relates to a buffer, in particular to a buffer using elastic colloid as a buffer 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, it is difficult to realize in practice. ...
