Title:
ADJUSTABLE STEEL RAIL VIBRATION ABSORBER AND STEEL RAIL VIBRATION ABSORPTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/240894
Kind Code:
A1
Abstract:
An adjustable steel rail vibration absorber, comprising: a pair of vibration absorption wedge blocks (11), which are used for being attached to waist portions of two sides of a steel rail (200), and absorbing vibration energy of the steel rail (200); and at least one balancing weight (12), which is detachably connected to a non-attachment surface (113) of the vibration absorption wedge block (11), and is used for adjusting the vibration frequency of the steel rail (200). The adjustable steel rail vibration absorber can effectively absorb vibration energy of a steel rail (200); and the vibration frequency of the steel rail (200) can be changed by means of adjusting the number of balancing weights (12), thereby adapting to the vibration characteristic frequencies of steel rails (200) in different regions, and better meeting an actual engineering condition. Therefore, the adjustable steel rail vibration absorber has relatively high flexibility and adaptability, is applicable to rails in different regions, and can achieve an ideal vibration and noise reduction effect, reduce the cost of rail construction and also reduce the difficulty of later maintenance.
