Contact network detector

product description

    The railway contact network geometric parameter measuring instrument is a special instrument and equipment for measuring the geometric parameters of the electrified railway contact network. The equipment is mainly composed of two parts, measuring frame and laser geometric parameter measurement.

1: The measurement rack is composed of a high-precision linear displacement sensor, a high-precision inclination angle sensor and an aluminum alloy profile. Through the host, it can accurately measure the rail gauge and (horizontal) ultra-high.

2: Measurement of geometric parameters of laser The measuring device of geometric parameters, which is a combination of a high-precision laser ranging sensor and a high-precision grating encoder, can guide and pull out the contact line of the catenary through the cooperation of the rotating mechanism and the video sighting device. Values, side limits, gauges, (horizontal) ultra-high geometry parameters for fast and accurate measurements.

Features:

1. The profile of measuring frame adopts industrial-grade aluminum profile, after special special die extrusion molding, and the surface is anodized and hardened, the mechanical strength is high, and it is not easy to be deformed and beautiful.

2. The insulated racks at the two ends of the measuring frame are molded by a special mold. The high hardness is not easy to be deformed and the insulation performance is excellent. It ensures the safety measurement between the two tracks.

3. Wear-resistant ceramic strips are installed on the ends of the two rail insulation brackets to ensure the measurement accuracy of the equipment and to facilitate maintenance, repair and replacement.

4. The connection method between the host head and the measuring stand adopts the total station to quickly connect the base structure, and the repeat accuracy and consistency of the device can be effectively ensured after quick disassembly.

5. Install spotlighting device to facilitate nighttime operation;

6, high-capacity rechargeable batteries, fully fired after measuring laser 10,000 times, continuous work 12 hours;

7. The use of industrial-grade TFT LCD screens constitutes a brand-new double-line video sighting system, realizing rapid sighting and greatly improving work efficiency;

8, no dead angle measurement, head rotation angle up to ± 120 degrees;

9, with measurement data storage, Bluetooth, GPS positioning;

10, laser emission power in line with national security standards;

11, the working temperature: -20 °C ~ 50 °C;

12, size: measuring frame 1618x66x125mm, host head 261x162x210mm;

13, weight: measuring frame 3.9kg, host head 2.6kg.
