[Industrialization Company Dynamics] Qingyan Tongchuang Innovative Technology Helps China's First "Simplified" Catenary High-speed Railway

A few days ago, the Yancheng-Nantong high-speed railway was opened for operation. The Yantong high-speed railway is an important part of the coastal railway in my country's "eight vertical and eight horizontal" high-speed rail network. It is also the first high-speed railway in northern Jiangsu with a design speed of 350 kilometers per hour. A new generation of "simplified" catenary system independently developed by my country.

The intelligent pre-matching of the wrist arm and hanging string, which are important components in the "simplified" catenary system, is realized through the innovation of the high-speed rail catenary wrist arm intelligent pre-matching platform and the high-speed rail catenary hanging string intelligent pre-matching platform developed by Qingyan Tongchuang Company.

These two sets of intelligent provisioning platforms are based on the technical requirements of simplified catenary. The practical application on Yantong high-speed railway has contributed to China's independent high-speed railway technology and accumulated experience.
"Simplification" means simplicity, unity, and standardization. This technology is the first full-line application in the Yantong Railway. It has completely changed the status quo of parts with different speeds, different specifications, and different processes before the Chinese railway catenary. Product manufacturing, on-site construction, operation and maintenance have entered a new era of modernization, standardization and intelligence. It is a demonstration line with completely independent intellectual property rights.

The wrist arm is mainly responsible for supporting the contact network system, which is an important part of the high-speed rail contact network, and its processing and assembly accuracy and bolt fastening accuracy directly affect the quality of the contact network. For a long time, the domestic high-speed rail catenary suspension system has generally used a multi-standard wrist-arm structure, which has many constituent parts and complex connection structure. On the basis of digestion, absorption and re-innovation, my country has independently developed a new generation of catenary, which unifies technical parameters, Simplify the equipment structure, reduce the types of parts, and improve the service cycle and service performance of key parts.

Project Site

More than 8600 sets of new generation catenary wrist arm devices for Yantong high-speed railway lineIt was pre-formed through intelligent equipment at the Yantong Railway Comprehensive Support Center of China Railway Construction Electrification Bureau in Haian. Entrusted by the construction unit,Qingyan Tongchuang Company has concentrated its backbone forces. After half a year of research and development, manufacturing and debugging, Qingyan Tongchuang Company has personally experienced the first set of simplified wrist arms that meet the standards and are assembled offline through the intelligent pre-configuration platform.

2. RobotsFully automatic production, wrist arm sizeAccuracy up to ± 2mmTo ensure that 100% of the pre-matched size of each wrist arm is fully inspected, the tightening torque of each nut meets the set value requirements, and the wrist arm manufacturing data is permanently tracked. Stable wrist arm pre-matching quality and data tracking can provide great help for the electrification of high-speed rail lines.
3. The wrist arm pre-matching platform is adoptedModular designIt can quickly respond to the improvement and innovation of simplified wrist arm technology, and realize the rapid upgrade iteration of equipment at a very small cost.
4. The pre-equipped platform can directly import the wrist arm data into the industrial control computerIntelligent data extraction, integrationTo provide processing and manufacturing data for sub-platform equipment. The software automatically arranges and combines the input data to optimize the use of materials,Reduce material waste and increase output.
5. The use of host computer communication control, with more than one.
6-axis robot system, bolt tightening gun system, multi-axis servo motor control system, hydraulic system, pneumatic system, code spraying system and truss system.Simplified wrist arm automatic prefabrication, intelligent assembly of pipe clamp assembly, length online detection, wrist arm code sprayingAt the same time, it has the functions of outputting relevant detection and construction data.

 

Hanging string intelligent assembly platform helps multiple high-speed railways under construction

In order to meet the high-speed rail catenary hanging string assembly size customization requirements and high precision requirements, Yantong high-speed rail also uses the high-speed rail catenary hanging string automatic intelligent pre-matching platform developed by Qingyan Tongchuang Company.

The company's proprietary technology ensures the automated assembly of key high-speed rail components and the production of the nominal length of the hanging string.Accuracy up to ± 1mm, High-precision online inspection ensures that 100 of each hanging string is qualified, effectively improving the assembly accuracy and quality. The whole set of equipment is advanced in technology, stable in operation, and easy to operate, which meets the new needs of the railway industry and is in a leading position in the industry.

The construction party organizes to visit the hanging string pre-matching platform.

This set of hanging string pre-matching platform is the third generation of products, which has been used in the Beijing-Xiong high-speed railway (the whole line of the Beijing-Xiong intercity railway! This set of robot intelligent assembly equipment helps to build intelligent high-speed rail), Yinwu high-speed rail, and He 'an high-speed rail, which has been unanimously approved by various engineering companies, project departments and high-speed rail contact network technical experts.

The crystallization of human wisdom and sweat

 

     

 

     

At the beginning of last year, affected by the new coronary pneumonia epidemic, the wrist arm project is facing many difficulties with tight commissioning schedule and many technical difficulties, and the project team of Qingyan Tongchuang Company has carried forward the Tongchuang people.Self-improvement, seeking truth and enterprisingThe professional spirit, made great efforts, a strong guarantee of the time limit for a project. Now that we have seen the smooth operation of the Yantong high-speed railway, weFeeling proud!
