A three-stage buffer suitable for step-by-step control of buffer sequence

Abstract

The invention relates to a three-level buffer suitable for controlling buffering sequence level by level. The buffer comprises a primary level buffer, a middle level buffer and a last level buffer. Each level of buffer comprises a cylinder body which is cylindrical and used for being filled with buffering media, a cylinder cover is arranged at the opening end of each cylinder body in a sealing mode, a piston rod is arranged in a center through hole of each cylinder cover in a sealing, movable and matching mode, and the right end of each piston rod is provided with a piston body component which is suitable for conducting piston motion in the cylinder body and is matched with the inner wall of the cylinder body in a movable and sealing mode. The cylinder body of the primary level buffer forms the piston rod of the middle level buffer, and the cylinder body of the middle 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 face of the piston body component of the primary level buffer. The piston body component of each level of buffer is suitable for adjusting the back-and-forth flow of media in a corresponding cylinder body to control the speed of the piston motion according to the medium pressure detected by the pressure sensor when the piston motion is conducted.

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 CN202149175 discloses a buffer, which is a two-stage buffer, and the maximum force F1max and the initial minimum force F2cmin of the medium in the first-stage buffer and the secondary buffer are different to control the first-stage buffer and the secondary buffer. The action sequence of the buffer; and it is mentioned in the manual that the capacity of the entire buffer is set according to the impact energy. However, in real work, because the impact energy is not constant, it may change, so it depends on the medium. Realizing the working order of buffers at all levels is difficult to realize in practice.
