Abstract

(57) [Summary] Railroad track tongue rail tip monitoring device [Purpose] By detecting the amount of displacement of the tongue rail tip of a turnout, it is possible to constantly monitor the contact state between the basic rail and the tongue rail and set a limit value. Allows foreseeable timing. [Structure] Since the diverter is based on the comprehensive and continuous displacement motion of each part of the conversion device, the close contact between the basic rail and the tongue rail is not monitored intermittently, but always at any time of the day or night. Need to be continuously monitored. This device consists of a plurality of non-contact sensor parts arranged on the side of the basic rail, a metal piece fixed to the tip of the tongue rail so as to face them, a sensor output amplifier part, a data processing device part, a display panel / warning. It is characterized in that it is composed of a light section, and that it performs a time-dependent data analysis process on the sensor detection data via the data processing apparatus section to constantly judge the safety level and predict the time to reach the safety management limit value. Tongue rail tip monitoring device for railway tracks.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention measures the amount of displacement of the tongue rail tip by a metal piece installed at the tip of the tongue rail for railroad tracks and a plurality of non-contact sensors installed on the side of the basic rail, and the detected data is measured by a data processor. This is related to a tongue rail tip monitoring device for railway tracks, which is calculated as monitoring management data and constantly monitors and manages the opening amount and inclination angle between the base rail and the tongue rail tip.

[0002]

[Prior art]

 As a method of monitoring the contact state between the tip of the railway tongue rail and the basic rail, a method of performing visual inspection by measurement using a dial gauge or intermittently detecting the displacement of the rolling rod is used. was there.

[0003]

[Problems to be solved by the device]

 However, each of the above detection methods has the following problems. Visual inspection using a dial gauge makes it difficult to make continuous measurements at any time. With the displacement of the rolling rod, the accuracy of measurement cannot be maintained due to the bending of the rolling rod, the looseness of the mounting part, and the generation of gaps over time. Therefore, the applicant measured the opening amount between the tip of the tongue rail and the basic rail and the tilt angle at the same time with high accuracy, and the momentary displacement amount through the data processing device, the maximum and minimum displacement amount within the specified period. The purpose of the present invention is to provide a tongue rail tip monitoring device that can calculate the average amount of displacement, accurately grasp the limit amount up to the specified value, and predict when the limit value will be reached.

[0004]

[Means for solving problems]

 Therefore, as a means to solve the above problems, one side of the metal piece is fixed to the tip of the tongue rail so as to face the contact surface of the basic rail, and multiple non-contact sensors are attached to the side surface of the basic rail. The metal piece fixed to the tip of the tongue rail is fixed so as to face one surface, and the displacement amount detection data in the horizontal and vertical tilt directions of the metal piece that is displaced simultaneously with the displacement of the tip of the tongue rail is processed. A tongue rail tip monitoring device for railroad tracks, which is configured to be input to the device.

[0005]

[Action]

 The present invention is configured as described above, and the non-contact sensor detects the close contact state of the basic rail and the tongue rail day and night, and the detection data of the opening amount and the tilt angle is highly accurate and can be used in the data processor every moment. Since it is input, the operating state of the tip of the tongue rail can be monitored accurately and efficiently, and safety management of the tip of the tongue rail can be easily implemented.

The operation flow of the device of the present invention will be described with reference to FIG. First, when the basic rail and tongue rail are in close contact with each other, a plurality of non-contact sensors placed on the side surface of the basic rail facing the one surface of the metal piece fixed to the tip of the tongue rail are attached to the metal. The sensor output intensifier 9 adjusts the sensor output level to 0 by bringing them close to each other so as to form a slight gap.

With the above initial settings, the data processing device stores that the basic rail and the tongue rail are in close contact.

When the tongue rail is displaced from this contact state and an opening distance or an inclination distance is generated, sensor detection data corresponding to the displacement distance is input to the data processing device.

With the sensor detection data input as described above, it is possible to judge the safety level based on the momentary displacement amount via the data processing device and predict the time when the limit value is reached. To
