Product Description
列車運(yùn)行時(shí)，常常產(chǎn)生作用在鋼軌上的縱向力，使鋼軌作縱向移動，有時(shí)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(fā)生在復(fù)線鐵路的區(qū)間正線、單線鐵路的重車方向、下坡道上和進(jìn)站時(shí)的制動范圍內(nèi)。 線路爬行往往引起軌縫不勻，軌枕歪斜等現(xiàn)象，對線路的破壞性很大，甚至造成；車輛脫軌跑道，危及行車安全。因此，必須采取有效措施來防止爬行，通常采用防爬器和防爬撐來防止線路爬行。
1、穿銷式防爬器是由帶擋板的軌卡的穿銷組成的。安裝時(shí)，軌卡的一邊卡緊軌底，另一邊楔進(jìn)穿銷，使整個(gè)防爬器牢固地卡住軌底。這樣，鋼軌在受到縱向阻力時(shí)，由于軌卡的擋板緊貼著軌枕，于是軌枕和道訂就阻止鋼軌爬行。為了充分發(fā)揮防爬器的作用，通常在軌枕之間還安裝防爬撐，把3～5根軌枕聯(lián)系起來，共同抵抗鋼軌爬行。?
2、防爬器分為焊接式防爬器和緊固式防爬器，分別適用于多種型號的鋼軌。這種鐵路軌道用螺旋式強(qiáng)力防爬器，分為鑄造型和焊接型兩個(gè)形式，鑄造型是由凸、凹形軌卡、螺栓、承力板所組成；焊接型由軌卡、鎖軌扣、螺栓、軌擋和承力板所組成。這兩個(gè)形式的螺旋式強(qiáng)力防爬器是通過擰緊螺栓使軌卡緊緊卡住鋼軌，從而防止了鋼軌在機(jī)車行駛和剎車時(shí)造成的爬行現(xiàn)象，可減少鐵路事故的發(fā)生。
