Abstract
The utility model provides a kind of novel railway track sleeper backing plate of plastic cement, belongs to track component technology field, is intended to solve existing track tie plate slab integral unwieldy structure, and shrinkage is poor, the problem that equipped operation is complicated.The track sleeper backing plate main body that its adopts conjunctedly bottom the dual-side be made up of thermoplastic polyester elastomer and rubber mixture is shaped with supporting leg limit and is shaped with rectangular tabular track sleeper backing plate body of expansion strip groove at its end face and bottom surface.Its overall structure is simple and practical, and shrinkage is strong, and resistance to ag(e)ing is good, and application life is long, and equipped operation is easy, is applicable to track construction.
Description
Technical field
The utility model belongs to a kind of backing plate be placed under railway track in track component technology field.
Background technology
Growing along with railway transportation, especially the lifting of train speed and continuing to increase of carrying capacity, also more and more higher to the technical requirements of track.In known technology, the existing plane rectangular track sleeper backing plate main body being placed in the backing plate between railway track and sleeper and mainly adopting rubber to make, is drilled with screw hole in four bights of backing plate main body, limit by its structure, its overall structure is clumsy, and shrinkage is poor, rolls and impact is easy to extension by train, follow the string the cushioning effect padded, in addition resistance to ag(e)ing is poor, and application life is low, and is adopt screw to connect, equipped operation is complicated, makes troubles to use.
Utility model content
In order to overcome the deficiencies in the prior art, solve existing track tie plate slab integral unwieldy structure, shrinkage is poor, the problem that equipped operation is complicated.It is simple and practical that the object of the utility model is to provide a kind of overall structure, and shrinkage is strong, and resistance to ag(e)ing is good, and application life is long, is equipped with the novel railway track sleeper backing plate that operation is easy.
The technical scheme in the invention for solving the above technical problem is:
A novel railway track sleeper backing plate for plastic cement, the track sleeper backing plate main body that its adopts conjunctedly bottom the dual-side be made up of thermoplastic polyester elastomer and rubber mixture is shaped with supporting leg limit and is shaped with rectangular tabular track sleeper backing plate body of expansion strip groove at its end face and bottom surface.
The novel railway track sleeper backing plate of above-mentioned plastic cement, any one of the expansion strip groove of described track sleeper backing plate body end face and bottom surface to be 3-6 sliver transvers section be square recess bar groove, trapezoidal recess bar groove, semi-circular indentation bar groove, or other is suitable for the recess bar groove of shape.
Above-mentioned novel railway track sleeper backing plate, track sleeper backing plate body inner clip contains 1-3 layer strengthens gauze, or mixture has reinforcement short fiber in track sleeper backing plate body, or track sleeper backing plate body inner clip contains 1-3 layer reinforcement gauze and mixture has reinforcement short fiber.
When the utility model makes, after compounding rubber, add thermoplastic polyester elastomer and mix, reenter that a plastic injection molder shot is shaping makes product.During use, according to designing requirement, on the sleeper completed, this novel track sleeper backing plate is contained on sleeper by the supporting leg checkpost of two side bottoms, steel rail laying on backing plate.This novel track sleeper backing plate body is shaped with the expansion strip groove of spill, also add reinforcement stratum reticulare, bulk strength is high, shrinkage is good, roll by train and can bounce back after impacting, play the cushioning effect of cushion, especially the backing plate that the thermoplastic polyester elastomer adopted and rubber mixture are made, to form material structure weatherability, oil resistivity, chemical resistance, uviolresistance, anti-flammability, water absorption resistance and resistance to ag(e)ing strong, application life is long, and be directly be equipped with operation, operating efficiency is high.
Because the utility model design have employed technique scheme, efficiently solve existing track tie plate slab integral unwieldy structure, shrinkage is poor, the problem that equipped operation is complicated.Also show through testing result on trial for several times, the advantages such as it compared with prior art has overall structure simple and practical, and shrinkage is strong, and resistance to ag(e)ing is good, and application life is long, and equipped operation is easy, are applicable to track construction.
