Abstract
Skretnice predstavljaju jedan od osnovnih elemenata gornjeg ustroja željeznica. Osnovni dijelovi od kojih su skretnice građene i koji omogućuju njezino pravilno funkcioniranje su prevodnički uređaj, skretničko srce i među tračnice. Glavna zadaća skretnica je razdvajanje kolosijeka na dva ili tri dijela, te omogućavanje prelaska željezničkih vozila s jednog kolosijeka na drugi. S obzirom na povećanje brzina vožnje vlakova, na skretnice se posvećuje posebna pažnja jer one predstavljaju jedan osnovnih uređaja željezničkog gornjeg ustroja za efikasno i sigurno odvijanje prometa. Paralelno s povećanjem brzina vlakova javlja se potreba za povećanjem kvalitete izrade skretnica kako bi se povećao njihov životni vijek i smanjili zahtjevi za održavanjem. Tako u različitim dijelovima svijeta imamo nove metode razvoja skretničkog sustava koji omogućavaju brže prolaske vlakova skretnicom uz održavanje kvalitete vožnje, te istodobno povećanje sigurnosti. U glavnom dijelu ćemo dati pobliži pogled prema nekima od zemalja sa najmodernijim tehnologijama izrade skretnica za velike brzine. Posebna pažnja se daje održavanju i zamjeni skretnica jer na njihovo održavanje odlazi otprilike 25 posto ukupnih troškova održavanja željezničkih kolosijeka. Zato je jako bitna kontrola i inspekcija skretnica, te svih njezinih dijelova pogotovo kako ne bi imali štetne i trajne posljedice za željeznički sustav .Prilikom održavanja skretnica postoje mnogobrojne metode i uređaji koji se koriste za provjeravanje njezine kvalitete i stanja. Prilikom zamjene skretnica, važno je skratiti proces ugradnje zbog povećanja dostupnosti usluge, te se u tu svrhu koriste posebna građevinska mehanizacija specijalizirane namjene.
Abstract (english)
Railway turnouts represent one of the main elements of the permanent way. The main parts of turnouts are switch panel, closure panel and crossing panel, which we will further described. The major task of turnouts is to separate the tracks into two or three tracks, and to enable the transition of railway vehicles from one track to another. Due to the increase in train speeds, special attention is paid to turnouts because they are a critical track component for efficient and safe railway operation. In parallel with the increase in train speeds, there is also a need for increase of the quality of turnouts and all parts that are directly related to it. Thus in different parts of the world there are new methods of developing turnout systems that allow faster trains to pass through the switch while maintaining ride quality and safety. In the main part of the paper, a closer look at some of modern technologies for high-speed turnouts will be given. Special attention is paid to the maintenance and replacement of switches, as they account for approximately 25 percent of the total maintenance cost of railway tracks. Therefore, the control and inspection of switches, and all its parts, are very important in order to mitigate harmful and lasting consequences for the railway system. For turnout maintenance, there are many methods and devices used to check its quality and condition. When replacing switches, special construction mechanization is used in order to reduce maintenance time and increase track availability.
