When a car passes through a tunnel, it will generate particularly strong airflow. Over time, the fixing parts are prone to loosen, causing cable leakage, power cable collapse, fiber optic repeater and antenna loosening, resulting in intrusion and potential safety hazards. In order to ensure the safe and stable operation of trains, it is necessary to conduct limit measurements on tunnel communication equipment and cables, in order to promptly identify and eliminate hidden dangers.

HYSG-3Railway tunnel leakage cable and antenna limit scanning measuring instrumentIt is a boundary detection instrument that uses electronic sensor systems, laser image acquisition systems, computer processing systems, etc. that are different from laser points and laser radar for uninterrupted full section inspection. Adopting a walking dynamic detection car, the instrument automatically scans and measures the limit data of tunnels and communication equipment (leaky cables, fiber optic repeater stations, base station antennas, video equipment, etc.), power cables (contour, horizontal limit, height limit, track gauge, track super elevation, etc.), and automatically measures and corrects curved sections. The software system completes real-time limit detection, data collection, data analysis and processing, display, and over limit judgment, and generates detection reports. Its operation is simple and fast, with high measurement accuracy and comprehensive measurement data, which improves detection efficiency and saves labor costs.

Features

1. Meet the requirements of JJG (Railway) 197-2022 "Verification Regulations for Railway Building Gauge Measurement Devices" and TB/T3308-2013 "Actual Gauge Measurement and Data Format for Railway Buildings".

2. The equipment adopts a fully automatic two-level trigger measurement system characterized by laser image scanning measurement, pulse triggering measurement, and full-time perception measurement control. It features high-resolution array scanning and automatic extraction of regional features, with high reliability, stable data, high accuracy, and long service life. Unlike laser points, which can only measure a single point, rather than the entire contour surface.

3. The instrument can simultaneously complete the scanning of the entire contour surface of the current equipment and cable, as well as automatically identify and measure horizontal protrusions and vertical highest points within 1 second. During the movement of the detection car, the instrument automatically and simultaneously measures, displays, and saves complete original records of data such as level, height, superelevation, and exceedance values, equipment images, track status, etc. Curve segments are automatically calculated and corrected.

4. Measurement has comprehensiveness and high efficiency. The device collects thousands of data points and identifies and measures the most unfavorable point data in less than 1 second. It scans the entire section without delay, making the measurement more comprehensive and faster.

5. Structural features: The probe and detection car adopt an integrated structure, and the probe adopts a bracket free design, which does not require assembly, does not produce vibration displacement, and eliminates mechanical errors; The device has portability; The material of the running wheel has good insulation properties.
