The invention discloses a turnout detection system which comprises a distance measuring device arranged on a track bed and used for measuring the states of a switch rail and a stock rail; a protectivecover which comprises a protective shell and a movable piece, wherein the protective shell is fixedly arranged on the track bed, one end of the movable piece is arranged in the protective shell, andthe other end of the movable piece is exposed out of the protective shell and abuts against the switch rail; when the switch rail moves, the movable piece synchronously moves along with the switch rail; the distance measuring device is arranged in the protective shell and used for measuring the displacement of the movable piece. According to the turnout detection system, the protective cover is arranged, no matter which state the switch rail is in, the protective cover is attached to the switch rail, and the problem that the laser displacement sensor is shielded by rain, snow and dust is solved.

    本发明公开了一种道岔检测系统,包括测距装置,测距装置设置于轨道道床上,用于测量尖轨与基本轨的状态;还包括防护罩,防护罩包括防护壳和活动件,防护壳固定设置于轨道道床上,活动件的一端设置于防护壳内,活动件的另一端外露于防护壳,并与尖轨抵接;当尖轨运动时,活动件跟随尖轨同步运动;测距装置设置于防护壳的内部,且测距装置用于测量活动件的位移量。本发明的目的在于提供一种道岔检测系统,在该系统中,设置有防护罩,无论尖轨处于哪种状态下,防护罩均与尖轨贴合,解决雨雪和尘沙遮挡激光位移传感器问题。
