The invention relates to the technical field of rail detection devices, in particular to an ultrasonic-based rail detection device which comprises a rail and a detection vehicle body, steel rails are arranged on the outer walls of the two sides of the top end of the rail, mounting plates are fixedly connected to the outer walls of the two sides of the bottom of the detection vehicle body, and first ultrasonic emitters are mounted on the inner walls of one sides of the mounting plates; a second ultrasonic transmitter is mounted on the inner wall of the other side of the mounting plate, and a first ultrasonic receiver and a second ultrasonic receiver are sequentially mounted on the outer wall of the mounting plate from left to right; pigment is output from the first spray pipe and the second spray pipe and accurately sprayed to the defect position on the steel rail, the steel rail detecting and positioning effect is further enhanced, when the defect is small, the sliding amplitude of the first screen plate or the second screen plate is small, mesh overlapping is small or the interval is long, consequently, the sprayed pigment is less, and when the defect is larger, the sprayed pigment is more. The maintenance scheme can be quickly determined according to the size and specification of the pigment mark, and the detection efficiency of the rail is improved.

    本发明涉及铁轨检测装置技术领域,具体是一种基于超声波的铁轨检测装置,包括轨道和检测车体,所述轨道顶端的两侧外壁设置有钢轨,所述检测车体底部的两侧外壁固定连接有安装板,所述安装板的一侧内壁安装有超声波发射器一,所述安装板的另一侧内壁安装有超声波发射器二,所述安装板的外壁从左到右依次安装有超声波接收器一和超声波接收器二;本发明使颜料分别从喷管一和喷管二输出,精准喷射在钢轨上缺陷位置,进一步增强钢轨检测定位效果,且缺陷小时,网板一或网板二的滑动幅度小,网眼的重合小或者间隔长,导致喷出的颜料少,缺陷更大时喷出的颜料也更多,便于根据颜料标记的尺寸和规格快速确定维护方案,提高了铁轨的检测效率。
