Parallel type self-resetting efficient buffering brake device

Abstract

The invention discloses a parallel type self-resetting efficient buffering brake device which comprises a connecting rod and two identical buffering brake mechanisms, wherein the two buffering brake mechanisms are symmetrical; one ends of the two buffering brake mechanisms are connected through the connecting rod; and each of the buffering brake mechanisms comprises a brake outer cylinder, a brakeinner cylinder, an annular sealing element of a brake inner cylinder end cover sealing ring, a first frictional plate, two limiting bolts, a plurality of disk springs and two second frictional plates. The first frictional plate and the two second frictional plates are fastened together through bolts; efficient energy dissipation is realized through metal yield, generation of heat by friction andviscous damping; the brake inner cylinder is embedded in the brake outer cylinder to be filled with liquid, and a liquid flowing hole formed by the interval between the brake inner cylinder and the brake outer cylinder plays a hydraulic brake effect during the braking process; and the disk springs provide resilience for the device through the elastic deformation of the material. The parallel typeself-resetting efficient buffering brake device is used for buffering huge impact load and realizes resetting and has the advantages of being excellent in parallelism, smooth in buffering and counter-recoil, steady in brake force, light in weight, high in buffering performance and large in energy dissipation.

Description

technical field [0001] The invention belongs to the field of buffer devices, in particular to a parallel self-resetting high-efficiency buffer brake. Background technique [0002] The parallel self-resetting high-efficiency buffer brake is a new type of buffer and shock absorbing device. This device can not only serve as the anti-recoil device of the current artillery, but also act as an earthquake buffer and anti-shock device. [0003] In the article "Seismic Analysis of Self-resetting Frictional Damping Steel Frame Buildings", Zhu Songye proposed a self-resetting frictional energy dissipator, which uses high-strength bolt connections and superelastic nickel-titanium alloys for frictional energy dissipation, but there is prestress The material memory alloy is expensive and the recovery force is greatly affected by temperature, the anchorage of the composite steel strand is relatively complicated, the stiffness degrades quickly after energy consumption, and the residual defo...
