HYJCG-1Hand push contact rail measuring instrumentPortable multifunctional detection device for contact rail Non contact third rail parameter detector Portable third rail image measuring instrument

HYJCG-1Hand push contact rail measuring instrumentIt is a device that uses machine vision technology to measure the geometric parameters of the third rail of the subway, realizing fixed-point static measurement and dynamic continuous measurement of relevant technical parameters such as the guide height and pull-out value of the contact rail, ensuring the installation accuracy of the contact rail equipment, reducing the labor intensity of personnel during the installation process, and improving labor efficiency; At the same time, it also provides real and accurate data reference for the daily maintenance of the contact rail, ensuring stable and reliable current collection between the collector shoe and the contact rail, which is of great significance for the safe, stable and reliable operation of subway trains.

Feature Introduction

1. The instrument adopts a manual or automatic walking detection trolley, with three working modes: dynamic measurement mode, static fixed-point measurement mode, and manual measurement mode for automatic continuous measurement without stopping. It realizes real-time high-definition image acquisition and automatic continuous, non-contact detection of geometric parameters of the return rail, end bends, protective covers, expansion joint clearances, bolts, and wear values of the receiving surface (some functions need to be selected).

2. High definition video recording can be selected for the current receiving surface and surrounding areas of the contact rail, which can clearly reflect the state of the current receiving surface.

3. Using positioning sensors, combined with inherent information of the line and database positioning technology, accurately locate the fault point of the contact rail.

4. The device can detect and measure data in less than 0.5 seconds, with full cross-section measurement and faster speed.

5. Structural features: The equipment adopts an integrated structure as a whole, without the need for assembly, reducing errors. The cover plate can be unfolded for immediate use, and there is no need to assemble or disassemble components before and after equipment use; The inspection car is made of aviation aluminum, which has high strength, light weight, and is easy to carry; The device can switch the pushing direction without turning the body.
