Background technology
Railway traffic engineering has been widely used in the fields such as state-owned railroads passenger and freight transportation, city passenger's communications and transportation, closely
It is rapidly developed over year, especially city track traffic engineering undergoes an unusual development rapidly, including subway, light rail, tramcar etc.,
It is to improve the effective means of Urban Traffic Jam Based.But, railway traffic system is in the life, production active belt given people
While convenient, also turn into the occurring source of new noise and vibration.Especially in intensive residential area, commercial center and work
Industry area, railway traffic system has had resulted in very important vibration and noise pollution.
Especially in intensive residential area, commercial center and industrial area, railway traffic system has had resulted in very important
Vibration and noise pollution.With the increasingly raising that people are required quality of life, this vibration and noise pollution are increasingly drawn
Play the concern of the public.In addition, in the units such as high-tech manufacturing enterprise, hospital and scientific research institution, some highly sophisticated devices are to week
Enclosing the sensitivity of ambient vibration increasingly increases, and this also proposes higher requirement to setting up defences for new vibration pollution source.Therefore,
The vibration of railway traffic system and the pollution of Noise upon Environment are controlled, has become what field of environment protection was urgently studied and solved
Major issue.
Damping fastening of the prior art carries out vibration damping using in-orbit lower laying rubber mat plate mostly, or double-deck iron chair it
Between cushioning intermediate rubber backing plate, then coordinate rubber tie plate under rail carry out vibration damping.Their shortcoming is：The dynamic displacement of the former rail
It is larger；Latter configuration is complicated, and amount of parts is more, and cost is high.
In addition, during the construction and operation of railway traffic engineering, because of the complexity of integrated condition, track occurs
Error is unavoidable, if error exceeds limit value, it will operation is impacted.Need periodically to examine track and structure
Survey, find beyond the error limited, it is necessary to elimination error of adopting an effective measure in time, it is ensured that operation security.For example, with track
After being used for a long time, existing iron chair combining structure can produce vibrations, release, the problems such as stability is poor, just in case failure is produced, general
Serious safety problem can be brought to numerous passengers on train and train.
Therefore, in order to solve the above problems, it is the class of the invention to be studied to propose a kind of lock-up type damping steel rail fastener
