Abstract
The utility model discloses a damping device with a limit function, comprising a top plate (5), a bottom plate (25) and a damping spring (21), wherein the top plate (5) is provided with an upper sleeve (5a) which is extended downward from the bottom surface of the top plate (5); the bottom plate (25) is provided with a lower sleeve (25a) which is extended upwards from the top surface of the bottom plate (25); and the damping spring (21) is arranged between the top plate and the bottom plate. The lower sleeve (25a) is filled with a damping material (22), and the upper sleeve (5a) is sheathed in the lower sleeve (25a). Thus, when the top plate (5) bears the load in a vertical direction, the lower end surface of the upper sleeve (5a) and the top surface of the bottom plate (25) exist a certain static distance (h). The damping device can largely save the use level of a damping agent and reaches a better damping effect at the same time. The damping sleeves provide a vertical limit function for emergency protection in spring fracturing, so that the damping device can provide emergency safety measures in extreme situations to prevent a spring fracturing accident from endangering the safety running of a train, and the safety control coefficient of a floating track bed is largely increased.

Technical field
The utility model relates to a kind of noise in the track traffic or device of vibration eliminated, and relates in particular to a kind of damping device structure that is used for orbit traffic floating board vibration isolation road bed system.
Background technology
Along with high speed development of national economy, track traffic is convenient, quick, punctual, energy-conservation with it, effectively alleviate the advantage that traffic above-ground is blocked up, and becomes the development focus that urban traffic is built rapidly.Can produce certain negative effect to environment along the line but its vibration and noise pollutes also, must build the vibration insulation and noise reduction measure of taking necessity the same period.What wherein effect of vibration and noise reduction was best still is the plate vibration isolation road bed system of floating that is made of damping spring.
Fig. 2 shows a kind of damping structure of at present existing floating ballast bed damping spring vibration isolator, comprise up and down top board 5, the base plate of arranging 25 and be placed in therebetween damping spring 21, top board 5 soffits are established upper bush 5a, base plate 25 upper surfaces are set sleeve 25a, link to each other by adapter sleeve 24 between sleeve 5a, the 25a up and down, sleeve 5a, 25a fix the upper and lower side of adapter sleeve 24 respectively with up and down.Inject fluid damping material 22 in the lower sleeve 25a or be provided with solid damping material 22, make damping spring 21 be immersed in fluid damping material 22 or the embedding solid damping material 22.The problem that this structure exists is: because spring 21 just is locally bathed in the fluid damping material or embeds among the solid damping material, inhomogeneous and the relativity amplitude of its damping action can only be the inverse of the number of coils, can't give full play to the damping action of damping agent with respect to bulk deformation (being the maximal rate input); On the other hand, just in case when spring 21 fatigue fractures occurring, it is effectively emergent spacing that existing damping structure can't provide, and causes floating ballast bed excessive convergence easily, gently then destroys the vehicle operating ride comfort, heavy then might jeopardize traffic safety.
Summary of the invention
The utility model provides a kind of damping spring floating track bed damping device with limit function at the problem that above prior art exists.This damper not only has the more damping of high-efficiency and economic, and under extremity, can provide emergent safety measure, make when the continuous mutually fatigue fracture of spring in enormous quantities in the safe range that floating ballast bed local subsidence amount is limited to several millimeters, prevent that disconnected spring accident from jeopardizing the safe passing of train, thereby increase substantially floating ballast bed safety guarantee coefficient.
For achieving the above object, the utility model is by the following technical solutions:
A kind of damping device with limit function comprises: top board has the upper bush that is extended by its bottom surface downwards; Base plate has by the upwardly extending lower sleeve of its end face; Damping spring is placed between top board and the base plate, wherein, is injected with damping material in the lower sleeve, and upper bush is sleeved in the lower sleeve, makes when top board bears the loading of vertical direction, and the lower surface of upper bush and the end face of base plate are at a distance of certain passive distance h.
Wherein, described damping spring is enclosed within described lower sleeve outside.
