China's high-speed rail track automatic detection technology has reached the international advanced level
Xinhua News Agency, Beijing, June 13 (Zi Zhongxi, Wang Yiwei) The 15,000th high-speed rail CRTSIII track plate qualified by intelligent robots was launched on the 13th at the Beijing-Shenyang high-speed railway Gyeonggi section of the board factory, which marked the automatic detection of high-speed rail track in China. The technology has reached the international advanced level.
According to reports, this technology has been jointly researched by China Railway 22nd Bureau Group, Southwest Jiaotong University, high-speed railway safety operation space information technology national and local joint engineering laboratory and other related experts and technicians. After more than two years, the company successfully developed integration. High-speed railway CRTSIII track plate automatic detection system for intelligent robots and 3D imagers. The inspection process is consistent with the production process of the track plate. No manual intervention is required. The inspection time of each track plate is shortened to 6 minutes, and the detection accuracy is plus or minus 0.15 mm, which fully meets the requirements of high-speed railway construction specifications.
Liu Jingan, an academician of the Chinese Academy of Engineering, said that the technology has improved the level of intelligent detection of high-speed railway track panels in China, and promoted the high-end evolution of China's high-speed rail parts testing to "smart detection" and "smart measurement", adding new advantages to China's high-speed rail technology. .
According to Qin Fei, the project leader of the technical research group and the project manager of the Beijing-Shenyang section of the China Railway 22nd Bureau Group 2, the CRTSIII track plate is a high-speed rail product developed by China with complete independent intellectual property rights. The fasteners used in the track plate have very high precision requirements, and the allowable deviation is plus or minus 0.5 mm. Previously, it took more than 40 minutes to detect a track plate.
NPT Hydraulic Fittings are a type of hydraulic fittings designed to be used with NPT (National Pipe Taper) threads. These fittings are used to connect hydraulic hoses and pipes in various hydraulic systems, such as those found in industrial equipment, construction machinery, and automotive applications.
NPT hydraulic fittings are made from high-quality materials such as stainless steel, brass, and carbon steel. They are designed to withstand high pressure and temperature, making them ideal for use in demanding hydraulic applications. The fittings come in a wide range of sizes and configurations to fit different types of hydraulic systems.
One of the main benefits of NPT hydraulic fittings is their ease of installation. They can be quickly and easily installed by hand without the need for special tools or equipment. This makes them a popular choice for applications that require frequent maintenance and repairs.
Overall, NPT hydraulic fittings are a reliable and versatile choice for hydraulic systems of all kinds. Whether you are building a new hydraulic system or upgrading an existing one, NPT hydraulic fittings offer the durability, ease of installation, and flexibility needed to get the job done right.
