                                                                    鐵路是供火車等交通工具行駛的軌道線路。鐵路線路是由多種鐵路配件組合而成的,且不同的鐵路配件,安裝在不同的部位,發揮著不同的作用。一個鐵路運輸系統包括很多元素,如車輛、軌道、各種調度控制、通訊信號和監控預警設備以及相關的管理制度和操作人員等,而且它們之間是相輔相成的,如果沒有合適的系統,火車將無法順利地運行。除了浙西系統,鐵路還會有很多的配件,為了能讓大家更進一步的了解鐵路配件,鄭州華銳將針對鐵路配件的種類及其作用進行簡單介紹。


                                                                  鄭州華銳來說說鐵路配件的作用


                                                                   鋼軌是鐵道器材是鐵路的重要器材,鋼軌是鐵路器材的主要標志。為了有效地抗輪軌橫向力,在鋼軌外側安裝的部件。軌撐一般安裝在小半徑曲線軌道外股鋼軌的外側,以防止列車通過曲線時,過大的橫向力造成軌道橫向位移過大,甚至造成鋼軌的翻倒。一般軌撐用于木枕軌道較多。在大多數道岔尖軌部位,在基本軌外側也安裝軌撐,以提高鋼軌的橫向剛度,軌撐的形狀也較多。


                                                                    列車運行時,常常產生作用在鋼軌上的縱向力,使鋼軌作縱向移動,有時甚至帶動軌枕一起移動。這種縱向移動,叫做爬行。爬行一般發生在復線鐵路的區間正線、單線鐵路的重車方向、長大下坡道上和進站時的制動范圍內。軌枕既要支承鋼軌,又要保持鋼軌的位置,還要把鋼軌傳遞來的巨大壓力再傳遞給道床。它需要具備一定的柔韌性和彈性,硬了不行,軟了也不行。列車經過時,它可以適當變形以緩沖壓力,但列車過后還得盡可能恢復原狀。軌枕包括木枕、混凝土軌枕。


                                                                    彈性扣件的扣壓件主要是鐵路彈條,它通過彈條的彎曲和扭曲變形,產生扣壓力作用在軌道上,長期有效地保證鋼軌之間的可靠連接,盡可能保持軌道的整體性,阻止鋼軌相對于軌枕的縱橫向移動,確保軌距正常,從而保證軌道車輛行駛安 全。另外由于火車車輪與鋼軌的接觸屬剛性接觸,因此不可避免產生震動,而彈條特殊的彈性結構使其還具有吸收車輛駛過時產生的沖擊能量,達到減震的作用
