Abstract
The utility model relates to a floating plate type ballast steel spring and rubber compound vibration isolator, which comprises an inner barrel of the vibration isolator, an outer steel spring, an inner steel spring, an outer rubber spring, an outer barrel of the vibration isolator, a baffle, a pressing block, a pressing base and a bearing frame, and is characterized in that the outer rubber spring is arranged between the outer steel spring and the outer barrel of the vibration isolator, and the inner rubber spring is arranged between the inner steel spring and the inner barrel of the vibration isolator. The utility model has the advantages of novel design, stable structure, small oscillation and low noise.
Description
Technical field
The utility model has related to a kind of track traffic vibration isolation, noise abatement floating slab railway roadbed vibration isolator of being used for, and belongs to buffer device.
Background technology
Along with the develop rapidly of China's urban economy, urban rail transit construction is generally risen, for the vibration that solves track traffic better, noise interference, the pollution to surrounding environment, essential shock insulation, the noise abatement problem of solving of train operation.
Steel spring isolator shock insulation, noise abatement mechanism are: rigidity and the elasticity of utilizing steel spring self to be had, support dynamic and static load and play damping vibration attenuation, noise reduction effect.Steel spring should adapt to different load, deflection (permission relative displacement) and than the requirement of lower resonant frequency,, but the metal spring damping is less, and damping ratio is about about 0.005, and the anti-vibration performance during middle and high frequency is relatively poor; Because rail transit train is a variable-speed operation, entering the suffered exciting force of vibration isolation zone steel spring makes the steel spring three-dimensional stressed, very for a short time being easy to generate of steel spring lateral stiffness is harmful to swing, the control of should adopting an effective measure, the application rigidity that present domestic market steel spring vibration isolator has is spacing, the swing of restriction steel spring, but have a strong impact on effectiveness in vibration suppression; The application thickness organic matter that has adds and fills spacingly, but the lateral stiffness that increases is limited, the teeter after can not solution spring stress in full force and effect, and load barycenter and the displacement of vibration isolator spring center are still bigger, also influence vibration isolation, the noise reduction effect of vibration isolator.
Summary of the invention
The purpose of this utility model is to provide a kind of floating slab roadbed steel spring spring, rubber shock absorber, and it has solved the problem of the spring stress teeter in floating ballast bed.
To achieve these goals, the technical scheme of invention employing comprises: vibration isolator inner core, outer steel spring, interior rubber spring, interior steel spring, outer rubber spring, vibration isolator urceolus, baffle plate, briquetting, wedge, bearing support are formed.It is characterized in that being provided with the outer rubber spring between outer steel spring and the vibration isolator urceolus, be provided with interior rubber spring between interior steel spring and the vibration isolator inner core.
Floating slab track steel spring, rubber composite vibration isolator are compound rubber springs between steel spring and vibration isolator urceolus outside, and an also compound rubber spring between interior steel spring and vibration isolator inner core forms steel spring, rubber spring composite construction.Utilize certain rigidity of rubber spring and elasticity to limit teeter after steel spring is stressed effectively, do not influence vertically moving both vertically of steel spring again, guaranteed floating slab track steel spring, the good vibration isolation of rubber composite vibration isolator, noise reduction effect.
The utlity model has modern design, Stability Analysis of Structures, characteristics such as swing is little, noise is low.
Description of drawings
Accompanying drawing 1 is the utility model sectional structure schematic diagram.
In the accompanying drawing, 1 is the vibration isolator urceolus, and 2 is outer steel spring, and 3 is interior rubber spring, and 4 is interior steel spring, and 5 is the outer rubber spring, and 6 is bearing support, and 7 is the vibration isolator inner core, and 8 is baffle plate, and 9 is briquetting, and 10 is wedge.
The specific embodiment
Device is applied among the subway technology as shown in drawings, is used for supporting the formula railway roadbed of floating.At first with outer rubber spring 5, outer steel spring 2, interior steel spring 4, interior rubber spring 3 by placing shown in the accompanying drawing between vibration isolator urceolus 1 and the vibration isolator inner core 7; Fixedly connected between the concrete of the formula of floating railway roadbed and the metal support frame 6, the metal wedge is welded in bearing support 6 inner surfaces, when wedge 10 is pressed on outer rubber spring 5, outer steel spring 2, interior steel spring 4, interior rubber spring 3 composition structures by briquetting 9, baffle plate 8, on the composite elastic structure that outer rubber spring 5, interior rubber spring 3 are protected.So on the one hand train enormous impact power bump composite elastic structural limitations outer steel spring 2 and interior steel spring 4 sideshakes; Rubber spring has increased the elastic force of elastic system vertical direction on the other hand, and cushioning effect obviously strengthens, and noise significantly lowers.
