Abstract

PURPOSE: To improve the efficiency and safety of the working with an accurate detection of the obstacle on the rail in a contactless manner by means of a device utilizing the reflected wave of the ultrasonic wave and light provided in front of the construction vehicle for the correction of the rail tracks.
CONSTITUTION: A detector 7 is provided in front of the rail lifting device 4 and has a device 7a for receiving the ultrasonic wave reflected from the road bed 6 and a transmitter 7b for transmitting the ultrasonic wave to the road bed 6. The mounting position of the transmitter 7a and the receiver 7b and the transmission intensity of the ultrasonic wave are selected so that the overlapping part between the transmission range and receiving range covers the inside of the rails 3 and 3. The detection of the obstacle is made depending on the level change of the reflected wave received by the receiver 7b.
