I would like to thank my parents, without them hard to pay itI am today, at this moment, will pay the highest tribute dedicated to you! II 摘要转辙机是道岔控制系统的执行机构。用于转换锁闭道岔尖轨或心轨,表示监督联锁区内道岔尖轨或心轨的位置和状态。具有道岔转换器、锁闭器和监督表示器的功能。作为转换器,具有足够大的牵引力以完成道岔尖轨或心轨的转换, 因故转换不到其极限位置时,应能随时操纵使其返回原来的位置。作为锁闭器, 当道岔尖轨或心轨转换到一个极限位置时,对尖轨或心轨实施锁闭,不应因外力辆除该锁闭;因故转换不到极限位置时,不应实施锁闭。 ZD6 系列电动转辙机是我国铁路使用最广泛的系列电动转辙机,它用于非提速区段以及提速区段的侧线上。 ZD6 型转辙机在铁路信号系统中有着不可磨灭的作用。关键词:转辙机、 ZD6 型转辙机、铁路信号 III Abstract Switch Machine is the executive body of the switch control system . For the conversion to lock the switch rail or nose rail , said supervision interlock switch rail in the region or the location and status of the heart rail . Turnout converter locking and supervision of said device functions . The converter is large enough traction plete the conversion of the switch rail or nose rail , for any reason to convert less than its limit position , should be able at any time manipulation to return to its original position . Locking device when the switch rail or nose rail converted toa limit position , the switch rail or nose rail implementation of the lock should not be due to external units in addition to the lock ; for some reason convert less than the limit position , should not be implementation of the lock .
