Product Description

本扣件系統(tǒng)在原有扣件結(jié)構(gòu)的基礎(chǔ)上重點(diǎn)對(duì)以下幾方面進(jìn)行優(yōu)化改進(jìn):1)提高扣件系統(tǒng)的絕緣性能;2)提高彈條的疲勞性能;3)同時(shí)考慮可安裝小扣壓力彈條和摩擦系數(shù)小的復(fù)合墊板,具備小阻力扣件的功能。

1)系統(tǒng)組成

扣件系統(tǒng)由彈條、螺旋道釘、平墊圈、軌距擋板、軌下墊板和定位于預(yù)應(yīng)力混凝土有擋肩枕的預(yù)埋套管組成。鋼軌高低調(diào)整時(shí)采用調(diào)高墊板。

2)結(jié)構(gòu)特征

本扣件為有螺栓扣件系統(tǒng),屬軌枕帶混凝土擋肩的彈性不分開(kāi)式扣件??奂哂幸韵陆Y(jié)構(gòu)特征:

a)采用螺旋道釘與套管配合緊固彈條,提高了扣件系統(tǒng)的絕緣性能。

b)可安裝多種彈條,既可安裝大扣壓力彈條也可安裝小扣壓力彈條。配合不同摩擦系數(shù)的軌下墊板(橡膠墊板或復(fù)合墊板),滿足不同線路阻力的要求。

c)利用工程塑料制造的軌距擋板調(diào)整軌距并起絕緣作用,減少扣件部件數(shù)量,避免調(diào)整軌距時(shí)影響螺旋道釘?shù)氖芰顟B(tài);

d)通過(guò)在軌下墊板與混凝土軌枕承軌面間墊入調(diào)高墊板實(shí)現(xiàn)鋼軌高低調(diào)整。

4)配套軌枕接口技術(shù)要求

扣件系統(tǒng)對(duì)軌枕接口的技術(shù)要求主要是承軌槽的型式尺寸和軌枕中預(yù)埋套管的埋設(shè)位置和精度。既有IIIa型有擋肩預(yù)應(yīng)力混凝土枕僅需在原釘孔位置按規(guī)定埋設(shè)預(yù)埋套管,彈條V型扣件系統(tǒng)便可與其相配套。
