[0006]

[Action]

 In the present invention, an extendable measuring rod is attached to a measuring carriage that can travel on rails by wheels, a tape measure is incorporated, and a wheel that can travel on the rail adjacent to the tip of the measuring rod is attached. If the measuring rod expands or contracts when the measuring carriage is moved, this is detected with a tape measure. Since the position of the tape measure does not correspond to the position of the required measurement interval, the detection result is corrected by the converter to correspond to the center interval of the track, and it is input to the data logger and recorded. According to the present invention, manual work is eliminated, manual input such as personal computer input at each measurement point is not required, and systematization from measurement to judgment is possible, improving work efficiency and data accuracy, and effectively managing track center interval. It becomes possible to do.

In FIG. 1 and FIG. 2, a generator 13, a converter 15 for correcting the data, and measurement data are recorded on a stand 12 of a measurement carriage 10 that can run on the rail 1 with three wheels 11. A data logger 15 for carrying out the measurement is mounted, and an extendable measuring rod 20 extending toward an adjacent line is attached.

Wheels 21 capable of traveling on the rail 2 of the adjacent track are provided at the tip of the measuring rod 20, and the wheels 21 rotate on the rail 2 in response to the traveling of the trolley, and also on the other end side. Has a tape measure 22 for detecting expansion and contraction of the measuring rod. The tape measure 22 is, for example, a commercially available digital tape measure, and the length of feeding or winding is detected as a digital value.

Since the position of the tape measure 22 is not in the center between the rails 1-1, the detection data is input to the converter 14 and corrected to the track center interval value, and the correction data is recorded by the data logger 15. ing. In addition to the function of converting the input measurement value into the orbital center interval and displaying it, the converter 14 uses a buzzer (not shown) when the measured value below the lower limit value is recorded by specifying the lower limit value of the measured value. It has the function of ringing to let you know the danger point.

As shown in part A of FIG. 1 and FIG. 3 which is a detailed view of the carriage, the output lead wire of the tape measure 22 incorporated in the end portion of the measuring rod 20 is connected to the converter 14, and the output of the converter is connected. The lead wire is connected to the data logger 15, and power is supplied to these devices from the generator 13. The measuring cart should be made of aluminum for easy transportation, and the wheels should be made of reinforced plastic to prevent track short circuit. Although not shown, a safety brake is installed on the measuring carriage to prevent runaway.

As for the measurement procedure, a measuring rod is attached to a measuring carriage, and the measuring rod is extended and set on a rail of an adjacent line. When the measuring carriage is moved on the rail and the measuring rod expands and contracts according to the change in the distance between the tracks, the amount of expansion and contraction is detected by the tape measure, and the detected data is corrected by the converter and input and recorded in the data logger. The data recorded in the data logger is transferred to a personal computer and, after data processing, input to the office computer to judge the measurement results. In this way, the conventional manual measurement and manual input to the personal computer are systematized, and the series of work from measurement to judgment is systematized.
