交叉渡線道(dao)岔(cha)是軌道(dao)線路中(zhong)普遍常(chang)用(yong)(yong)的一種(zhong)兩道(dao)相(xiang)互轉換(huan)行走的道(dao)岔(cha)。（1）軌距一致：如(ru) ZDK622 /4 /12，只用(yong)(yong)于600mm軌距（2）軌型相(xiang)符：可(ke)相(xiang)同或高一級，不能低(di)一級。
道(dao)岔(cha)(cha)全長(chang)(chang)L=75378mm，道(dao)岔(cha)(cha)前長(chang)(chang)a=13839mm，線(xian)(xian)(xian)(xian)(xian)(xian)路交(jiao)(jiao)叉(cha)(cha)中心水平(ping)距47700mm，道(dao)岔(cha)(cha)容許通過速度直線(xian)(xian)(xian)(xian)(xian)(xian)≤90Km/h，側線(xian)(xian)(xian)(xian)(xian)(xian)≤30Km /h，導曲(qu)線(xian)(xian)(xian)(xian)(xian)(xian)半(ban)徑R=180000mm，尖軌(gui)(gui)長(chang)(chang)度6450mm(圖(tu)(tu)號(hao)(hao)專(zhuan)線(xian)(xian)(xian)(xian)(xian)(xian)4142-6），基(ji)本軌(gui)(gui)長(chang)(chang)度11200mm（圖(tu)(tu)號(hao)(hao)專(zhuan)線(xian)(xian)(xian)(xian)(xian)(xian)4142-4、5），轍(che)叉(cha)(cha)長(chang)(chang) 度3588mm（圖(tu)(tu)號(hao)(hao)專(zhuan)線(xian)(xian)(xian)(xian)(xian)(xian)4143-4），銳角(jiao)轍(che)叉(cha)(cha)長(chang)(chang)度3108mm(圖(tu)(tu)號(hao)(hao)專(zhuan)線(xian)(xian)(xian)(xian)(xian)(xian)7514-3），鈍(dun)角(jiao)轍(che)叉(cha)(cha)長(chang)(chang)度4440（圖(tu)(tu)號(hao)(hao)專(zhuan)線(xian)(xian)(xian)(xian)(xian)(xian)7515-3），護(hu)(hu)軌(gui)(gui)長(chang)(chang)度 直線(xian)(xian)(xian)(xian)(xian)(xian)3600mm（圖(tu)(tu)號(hao)(hao)專(zhuan)線(xian)(xian)(xian)(xian)(xian)(xian)4143-5），側線(xian)(xian)(xian)(xian)(xian)(xian)3050mm（專(zhuan)線(xian)(xian)(xian)(xian)(xian)(xian)7521-4），銳角(jiao)護(hu)(hu)軌(gui)(gui)3050mm（圖(tu)(tu)號(hao)(hao)專(zhuan)線(xian)(xian)(xian)(xian)(xian)(xian)7522-3），護(hu)(hu)軌(gui)(gui)形式分(fen)開式可調(diao)護(hu)(hu)軌(gui)(gui)。總重(zhong)55.495T，木岔(cha)(cha)枕體積35.7立方米。型號(hao)(hao) 50-9#規(gui)格 5.3m交(jiao)(jiao)叉(cha)(cha)渡線(xian)(xian)(xian)(xian)(xian)(xian)道(dao)岔(cha)(cha)是礦井運輸交(jiao)(jiao)通航道(dao)中的重(zhong)要環節，所以你(ni)的質(zhi)量和安全的顧慮(lv)是必(bi)須的。
