Description
Technical field
The elastic force that the utility model relates to a kind of flexible member is improved one's methods and device, particularly relates to a kind of for Rail Transit System, is strengthened method and the device of resilient sleeper-bearing screen resilience, belong to technical field of rail traffic by reinforcing rib.
Background technology
For solving the serious inequality of Domestic Resources distribution and meeting socio-economic development demand, in recent years, heavy haul railway obtains develop rapidly, the demand of track fastener system is also constantly increased, along with the raising of railway operation speed and the increase of load-carrying weight, wheel track dynamic effect is aggravated, and rail clip system bearing condition is more and more severe.How under the prerequisite meeting orbit strength requirement, effectively extending the fastener system life-span becomes a large technical barrier.
Resilient sleeper-bearing is one of parts the most key in rail clip system, be used to keep on same track two rails apart from equal, and safety and signal system safety component in good condition, due to its elasticity, vibration can also be reduced significantly, keep roadbed not to be subject to the impact of train or load, improve the stationarity of train operation.But existing resilient sleeper-bearing design has following shortcoming:
(1) projection on matrix, groove or hole adopt interlaced mode to arrange, but be discontinuous layout substantially, backing plate screen resilience is not enough, and under different loads (axle weight), because the surface of the projection of resilient sleeper-bearing, groove or hole formation is in same level, existing resilient sleeper-bearing vertical stiffness is single, is difficult to meet railway transportation demand.
(2) projection of existing resilient sleeper-bearing, groove or hole adopt isolated design, under vertical or action of lateral load, transverse and longitudinal rigidity is less, easy generation Relative sliding, accelerate the wearing and tearing of backing plate, toe load of fastening declines, and then causes fastener to loosen, and affects rail system damping property and application life.
The structure of existing resilient sleeper-bearing, has three essential characteristics:
(1) basic structure of resilient sleeper-bearing is: matrix, projection, groove or the hole be arranged on matrix (one or both sides);
(2) being arranged in the projection on matrix, groove or hole adopts interlaced mode to arrange, is connected between each projection, groove or hole by matrix;
(3) material of resilient sleeper-bearing is configured to: the combination of certain macromolecular material or certain several macromolecular material.
Existing resilient sleeper-bearing is only focused on meeting vertical load bearing requirements mostly, but in train travelling process, then show performance level analysis too small, the dynamics of resilience is not enough, rail and iron chair is easily caused to occur laterally to slide, accelerated wear test destroys, and then cause fastener system to loosen, threaten the security of operation of train, then must change when may wear to a certain degree, this brings a large amount of inspections, adjustment and maintenance work to Rail Transit System, and the dynamics of the rigidity and resilience that therefore how to promote resilient sleeper-bearing horizontal direction also needs further research.
Do not find the patent identical with the utility model by domestic retrieval, but the patent similar to the utility model has following:
1. application number is 201320030477.5, name is called the utility model of " under a kind of iron chair resilient sleeper-bearing ", this utility model provides resilient sleeper-bearing under a kind of iron chair, comprise substrate and be positioned at the elastic body of upper surface of base plate and/or soffit, described elastomeric protrusions is in substrate surface, and the upper base edge lengths of described elastomeric longitudinal section is less than bottom length.This utility model improves the elastomer shape that resilient sleeper-bearing surface contacts with iron chair, the upper base edge lengths being set to longitudinal section is less than the shape such as taper, trapezoid boss of bottom length, elastic body on upper surface is connected with iron chair soffit, and the elastic body on soffit directly contacts with sleeper.When load constantly increases, elastic body and constantly oppressed and to bottom compression, the contact area of bearing surface then constantly increases, and the rigidity of resilient sleeper-bearing also increases thereupon; Ensure that the heat radiation drainage of this backing plate simultaneously.
2. application number is 201220695265.4, name is called the utility model of " a kind of thermoplastic elastic backing plate ", this utility model relates to a kind of thermoplastic elastic backing plate, belong to railway rubber materials, comprise backing plate body, the two ends of described backing plate body are provided with link slot, and backing plate body one end face is provided with multiple elongated slot, other end is provided with multiple supporting lug, the edge of backing plate body is provided with step through-hole, by increasing its elongated slot and multiple supporting lug on backing plate, the noise produced when reducing its train vibration influence, and the thermal diffusivity of backing plate is carried out by the structure design of its step through-hole, which adds its application life, also a saving the spillage of material of finished product.
3. application number is 201120361354.0, the utility model that name is called " a kind of two rigidity elastic rail pad ", a kind of two rigidity elastic rail pad, comprise elastic matrix, at the soffit of elastomer matrix, be provided with two bearing surfaces, be respectively a bearing surface and Second bearing face, a bearing surface and Second bearing face adopt different elastic stiffness respectively.A described bearing surface and Second bearing face are the plane of two differing heights with certain altitude difference, and wherein a bearing surface is higher than Second bearing face, form the plane of Second bearing face indent; A described bearing surface and the juncture area in Second bearing face are provided with transition groove; Transition groove is again to the groove of elastic matrix indent by Second bearing face; Described elastic matrix is software wear-resistant elastomeric, and bearing surface is Main Deformation, for realizing elastic damping function, provides carrying and distortion when Second bearing face is used for large load.The Low rigidity of this utility model meets the damping requirements of track, and secondary rigidity maintains rail level deflection, improves the safety of train operation while meeting comfortableness.
Although above-mentioned patent has all related to resilient sleeper-bearing, but above-mentioned patent does not all relate to the structure how improved reinforcing rib and projection and be cross-linked, therefore still there is performance level analysis too small, the dynamics of resilience is not enough, rail and iron chair is easily caused to occur laterally to slide, the deficiency that accelerated wear test destroys, therefore still needs to be improved further this.
