Vibration isolation device for track traffic

Abstract

The invention discloses a vibration isolation device for track traffic. The vibration isolation device comprises a vibration isolation inner barrel, a vibration isolation outer barrel (2) and a heightening seat (4), wherein the vibration isolation inner barrel is sleeved in the vibration isolation outer barrel (2); the heightening seat (4) is arranged in and in threaded connection with the vibration isolation outer barrel (2); the vibration isolation inner barrel comprises a base (1), an annular damping barrel (20), an upper support plate (15) and a shearing barrel (19); the annular damping barrel (20) is arranged on the base (1) and provided with an annular groove (20a); the annular groove (20a) is filled with damping liquid (20b); a vibration-damping spring (24) is arranged in the vibration isolation inner barrel; and the upper end of the vibration-damping spring (24) is pressed against the upper support plate (15), while the lower end is pressed against the base (1). The vibration isolation device has the advantages of compact overall structure, convenient installation and detachment, good vibration isolation effect, rapid after shock consumption and capability of realizing stepless heightening.

Description

technical field [0001] The invention belongs to the technical field of urban rail transit, and in particular relates to a vibration isolation device for rail transit. Background technique [0002] Urban rail transit has developed rapidly in recent years because of its remarkable characteristics such as large transport capacity, environmental protection, low energy consumption, safety and high efficiency. The impact of vibration and noise on the environment and the lives of residents in rail transit has become the focus of people's attention on urban rail transit construction, and it has also become one of the keys to the sustainable development of urban rail transit construction. Due to the limited vibration reduction effect of traditional vibration reduction technology in terms of vibration reduction and noise reduction, the vibration and noise generated when trains pass by will still directly affect people's lives and health, and also cause adverse effects on the surroundi...
