Abstract
The present invention relates to sleeper, and is especially one kind of clad elastic sleeper. The clad elastic sleeper includes concrete sleeper and elastic cladding material in the bottom and side faces and/or end faces. Cladding the concrete sleeper with elastic cladding material can raise the elasticity of track, lower the global rigidity one the track, reduce the mutual action between wheel and track, raise the comfort and safety of train and reduce the impact of train to the track.
Description
Technical field
The present invention relates to support the sleeper of railway track, specifically a kind of cladding type spring rail sleeper.
Background technology
The sleeper that track uses has three kinds in short, sleeper, concrete sleeper and be other sleeper of representative with the metal material.
Wooden sleeper because be subjected to wind, drench with rain, the erosion of natural environment such as Exposure to Sunlight, it is rotten to wear out, application life is short, needs periodic replacement; Owing to be subjected to factor affecting such as the forest reserves, China is superseded substantially at present, just can also see at some branch lines and station track.In addition, the track stability of sleeper is bad, inapplicable high-speed overload railway.
Concrete sleeper is the most widely used a kind of sleeper of present China, but concrete sleeper exists rigidity big, the elasticity deficiency, and train can pulverize efflorescence with ballast aggregate in running, produce frost boiling, emit disease such as white, plate knot of ballast bed, using after a period of time will the removable parts ballast aggregate; In addition, because the effectiveness in vibration suppression of concrete sleeper is poor, these defectives can be more serious under train heavy duty high-speed case.Therefore, must be transformed just concrete sleeper and can be applied to the high-speed overload situation.
On May 10th, 2006, disclosed name was called " railway concrete sleeper pillow is used rubber mat plate down " Chinese patent, and publication number is: CN2778866Y, its backing plate divide end face and bottom surface, are distributed with the parallel longitudinal direction groove on the backing plate end face, and the bottom surface is distributed with circular groove.This patent has solved the defective of the vertical effectiveness in vibration suppression difference of concrete sleeper to a certain extent, but backing plate misplaces with it when concrete sleeper shakes easily, himself intensity is far smaller than the contact strength with ballast aggregate, be easy to be punctured and fester, its application life is short, often maintenance, and this patent can only be played vertical damping, does not play horizontal and vertical damping effect.
On December 28th, 2005, disclosed name was called " Wholly coated rail sleeper and manufacture method thereof " Chinese patent, publication number is: CN1712637A, a kind of Wholly coated rail sleeper is disclosed, it comprises inner core and surrounds the shell of inner core, feature is that shell is the integral coating formula, in forming process, welding is attached to constituting one on the inner core.It is owing to use the form of integral coating, the waste clad material, increased cost of production, its inner core adopts special shaped steel in addition, only replace sleeper, be used in the low speed situation, and the railway of China has generally used concrete sleeper, the sleeper that only just uses special shaped steel to constitute under special circumstances and place, this scheme obviously is not suitable for China's actual conditions.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of local elastic sleeper that coats is provided, it can solve three-dimensional impact force and the bigger problem of amplitude that under existing train high speed, the heavily loaded situation track is produced, and long service life guarantees high speed, the heavy-duty safety operation of train.
The object of the present invention is achieved like this: a kind of cladding type spring rail sleeper, comprise concrete sleeper and elasticity clad material, and wherein the elasticity clad material is coated on bottom surface and side or bottom surface and end face or bottom surface, side and the end face of concrete sleeper.
In order to prevent that the elasticity clad material from being pierced through by ballast aggregate, the bottom surface portions that the elasticity clad material contacts with ballast aggregate is a composite structure, is composited by the high pressure-bearing bottom of intensity and the elastic layer of good springiness, and the pressure-bearing bottom is provided with the web frame shape structure of groove and boss.If the intensity of said structure does not still reach requirement under some specific occasion, can in the pressure-bearing bottom, embed the terylene cord.
The elasticity clad material has the coating mode of concrete sleeper: the elasticity clad material is coated on the side of sleeper and 2/3 surface and the bottom surface of end face; The elasticity clad material coats outer bottom surface and the two sides and the end face thereof in center of concrete sleeper; The elasticity clad material carries out inserted low group to the bottom of outer both sides, the center of concrete sleeper and coats; The elasticity clad material hangs down group to the bottom of outer both sides, the center of concrete sleeper and coats.The elasticity clad material is rubber, rubber and plastic or polyurethane elastomer, adopts one-step moulding method directly to combine with the concrete sleeper surface, utilizes the ramp type structure of elasticity clad material at cooling contraction and concrete sleeper, and it is fastened on the sleeper; Also can adopt the method for stickup directly to combine, it is fastened on the sleeper with the surface of sleeper.The sleeper outer surface the elasticity clad material can be V-shaped or the U type coat, reduce the consumption of elasticity clad material, reduce cost.For the more material of saving, bigger reduces cost, and the elasticity clad material that above-mentioned all elasticity clad materials that coat the sleeper bottom surface of modes are provided with interval trough or sleeper side is provided with at interval or the elasticity clad material of sleeper bottom surface and side is provided with interval trough and at interval.Shape at interval can be a rectangle, also can be oblong, also can be other geometries arbitrarily.
The beneficial effect of cladding type spring rail sleeper of the present invention is: have vertical, vertical, horizontal three-dimensional effectiveness in vibration suppression, acceleration and amplitude that sleeper is produced reduce greatly, noise when having alleviated train operation, prolonged the application life of sleeper, satisfied the speed-raising requirement of train, high speed, the heavy-duty safety operation of train have been realized, simultaneously owing in the coating process, adopt high temperature injection or high temperature/normal temperature moulding by casting, do not need to fix with anchor pole and viscose glue, reduced manufacturing procedure, and adopted partly coating, saved manufacturing cost.Enforcement of the present invention, the track integral rigidity is descended, improved the elasticity of track greatly, alleviated the interaction between wheel track, comfortableness and safety that train is taken have been improved, reduce, alleviate that impact force has reduced the ballast aggregate efflorescence to the destruction of track in the train travelling process, greatly reduce maintenance workload and expense.
Use proof through reality: when the present invention is applied to common rail, the wheel load change has reduced about 3%, rail wear reduces about 41%, railway roadbed permanent set accumulation deflection reduces about 70%, the ballast aggregate pulverization rate reduces about 44%, the maintenance workload reduces about 40%, saves consumption of materials 90%, but extension wire maintenance period 3-5.
When the present invention was applied to culvert, the vertical peak acceleration of sleeper had reduced about 40%, and ballast aggregate maximum vertical acceleration has reduced about 60%, and the vertical peak acceleration of cover plate has reduced about 90%.
When the present invention was applied to bridge, beam body maximum transversal amplitude had reduced about 64%, and beam body maximum vertical acceleration has reduced about 85%, and beam body maximum lateral acceleration has reduced about 95%.
