Abstract
The utility model provides an elastic cushion plate under an iron cushion plate. The elastic cushion plate comprises a substrate and an elastic body located on the upper surface and/or the lower surface of the substrate. The elastic body protrudes out of the surface of the substrate. The length of an upper bottom edge of a longitudinal section of the elastic body is smaller than the length of the lower bottom edge of the longitudinal section of the elastic body. According to the elastic cushion plate, the shape of the elastic body, contacting with the iron cushion plate, of the surface of the elastic cushion plate is improved and is designed to be a cone, a trapezoid, and the like, the length of the upper bottom edge of the longitudinal section of the shape is smaller than the length of the lower bottom edge of the longitudinal section of the shape, the elastic body on the upper surface is connected with the lower surface of the iron cushion plate, and the elastic body on the lower surface directly contacts with a sleeper. When load consecutively increases, the elastic body contracts toward the bottom due to consecutive pressure, the contact area of a bearing face consecutively increases, the rigidity of the elastic cushion plate also consecutively increases, and at the same time, heat dissipation performance and water discharge performance of the cushion plate are ensured.
Description
Technical field
The utility model relates to the elastic shock attenuation field of track, especially, relates to resilient sleeper-bearing under a kind of iron chair.
Background technology
China is carrying out urban rail transit construction on a large scale, and the damping noise reduction of track, safe, comfortable, the change rigidity of damping means, heat radiation, draining become a big technical barrier.Because the impact force that rail joint irregularity or wheel produce is the main cause that causes vibration, noise and track to worsen, therefore, need under track, to add backing plate rail is supported, play buffering, wheel hub weight is distributed to a plurality of fastener nodes.
In the development and Design process of resilient sleeper-bearing, traditional structure design is at the upper and lower surface fluting or borehole carries out the rigidity adjusting under iron chair, and draining and radiating effect are not very desirable.
The utility model content
The utility model purpose is to provide resilient sleeper-bearing under a kind of iron chair, carries out rigidity and regulates dissatisfactory technical problem to solve under the existing iron chair resilient sleeper-bearing.
For achieving the above object, the utility model provides a kind of (claim determines that the back replenishes).
The utlity model has following beneficial effect:
The utility model has improved resilient sleeper-bearing surface and the contacted elastomer shape of iron chair, it is set to the upper base edge lengths of longitudinal section less than shapes such as the taper of bottom length, trapezoid boss, elastic body on the upper surface is connected with the iron chair soffit, and the elastic body on the soffit directly contacts with sleeper.
When bearing load, the distortion of resilient sleeper-bearing mainly concentrates on the elastic body of lower convex platform layer, because elastic body is tapered or trapezium structure, when load constantly increases, elastic body and constantly oppressed and compressed to the bottom, the contact area of bearing surface then constantly increases, and the rigidity of resilient sleeper-bearing also increases thereupon; Satisfy the vibration and noise reducing requirement of (axle is heavy) under the different loads.
Because the upper and lower surface of substrate is elastomer layer, the heat that produces in the bearing load process is than the product good heat dissipation effect of groove and pore structure, and elastic body protrudes from substrate, the easier flat surface discharge along elastomeric gap and substrate of liquid.
Except purpose described above, feature and advantage, the utility model also has other purpose, feature and advantage.With reference to figure, the utility model is described in further detail below.

The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the utility model can be implemented according to the multitude of different ways that claim limits and covers.
Referring to Fig. 3 to Fig. 5, resilient sleeper-bearing under a kind of iron chair comprises substrate 1 and is positioned at upper surface of base plate 3 and/or the elastic body 2 of soffit 4 that described elastic body 2 is projected on substrate 1 surface, and the upper base edge lengths of the longitudinal section of described elastic body 2 is less than bottom length.When stressed, after last base is impacted, to the bottom compression, make the contact area of bearing surface strengthen, the carrying dynamics also strengthens thereupon, thereby is adapted to various load conditions.
Described elastic body can be arranged on the substrate surface one or both sides, all can reach the vibration and noise reducing purpose.The elastomeric height of both sides and arrangement mode can be according to the changes and inconsistent flexibly of the concrete condition of both sides.
Described elastomeric longitudinal section can be triangle or trapezoidal, and namely elastic body itself can be taper shape, boss type or polyhedron, does not influence the realization of present embodiment.
The upper base edge lengths of described elastic body 2 can be 0.01-0.8 times of bottom length, thereby all can reach the purpose that base downward base compression increases contact surface gradually.
As depicted in figs. 1 and 2, the spacing between the adjacent described elastic body 2 can be 0.3-1.2 times of described elastic body 2 base length, can determine according to actual conditions.Elastic body can be even distribution, and namely the spacing between each elastic body equates; Can arrange according to vertical and horizontal quadrature standard, perhaps arrange according to quincuncial pile, perhaps take other forms that are beneficial to vibration and noise reducing, heat radiation draining to arrange.
The 0.5-1.5 that the described elastic body 2 of each side highly can be described substrate 1 thickness doubly when leaving compression stroke, but when also having guaranteed elastomeric upright degree and being subjected to being positioned at iron chair compressing on the upper bottom surface, transmits the characteristic of pressure downward vertically.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
