From June 22 to 24, 2021, the three-day "2021 Shanghai International Advanced Rail Transit Technology Exhibition" was grandly held at the Shanghai New International Expo Center. More than 200 exhibitors and 20,000 professional visitors from all over the world gathered at the event. The sponsor: Urban Transportation Network; the organizer: Urban Public Transportation Branch of China Civil Engineering Society, China Rail Transit Science and Technology Alliance; the guiding unit: National Development and Reform Commission of the People's Republic of China, the Ministry of Science and Technology of the People's Republic of China jointly hosted the International Rail Transit Exhibition. Shengtong Intelligent Laser Equipment Group, as an outstanding enterprise representative in the field of laser cleaning, appeared at this rail transit industry event with its rail transit cleaning and maintenance solutions.

New starting point, new leap, domestic and foreign rail transit one-stop whole industry chain communication platform fully launched

The Shanghai International Advanced Rail Transit Technology Exhibition in 2021 is an authoritative industry event in the Asia-Pacific region, providing a valuable platform for promoting technical exchanges and cooperation between international and domestic peers, involving vehicles and parts, tunnels and underground engineering, rail transit communications, public works cleaning and maintenance, maglev air rail trains/cloud rail trains, vehicle interiors and materials, and electrified railway equipment.

Laser cleaning escorts future intelligent rail transit maintenance

2021 is the beginning year of the "14th Five-Year Plan". Focusing on transportation power, railway first, high-quality development orientation, and focusing on integrated development has become the consensus of industry people. As a leading enterprise in high-end laser equipment technology in the cleaning field, Shengtong Intelligent Laser has occupied a pivotal position in the field of laser cleaning. As a well-known laser processing equipment manufacturer, its products mainly include: laser cleaning series, laser rust removal series, laser deoxidation layer series, laser degreasing series, laser cultural relics restoration series, laser paint removal series, laser glue removal layer series, laser deplating coating series, intelligent laser cleaning series, laser cleaning automation solutions, etc. Products have been widely used in the field of railway rail traffic maintenance and maintenance.

Due to the fact that the rail is exposed to the air all year round and needs to face the natural environment of wind and rain, its surface is prone to rust. In order to ensure the smooth operation of the train, the railway department will regularly carry out the track rust removal work. The current track rust removal mainly relies on grinding and rust removal, including manual grinding and rust removal, and the use of large-scale rail rust removal grinders. Manual grinding and rust removal is the main way of rail maintenance at present, but its labor intensity is high, the operation is difficult, and the work efficiency is low. Large-scale rail rust removal grinders are more efficient than manual grinding and rust removal, but the rust removal equipment is large in size and needs to be used with its own generator. It is driven by a traction locomotive to run on the railway. The single cleaning cost is high, which has a great impact on the surrounding environment of the rail.

Laser cleaning is a new type of cleaning method. Laser cleaning technology is a cleaning solution using high-frequency short-pulse laser as the working medium. The specific wavelength of high-energy beam of light is absorbed by the rust layer, paint layer and pollution layer, forming a rapidly expanding plasma, and at the same time generating shock waves, which turn pollutants into fragments and are removed. The substrate will not absorb energy, will not damage the surface of the object to be cleaned, and will not reduce the surface finish. Laser cleaning equipment can work alone or with the robot arm cleaning operation. The cleaning cost is low, environmentally friendly and efficient. The cleaning effect is good and does not hurt the rail substrate. It gradually replaces the traditional cleaning method. The market capacity is large and the development prospect is promising.

Shengtong Intelligent Laser joins hands in the field of rail transit cleaning and maintenance for win-win cooperation

Shengtong Intelligent Laser, as a representative of high-tech enterprises in the field of laser cleaning at this rail exhibition, Mr. Rong Xiancheng, the general manager, was interviewed by Wang Xinyu, a reporter from the CCTV "Quality" program group, and discussed the company's development strategy and research and development direction. Mr. Rong said: Shengtong has experienced more than ten years of development in the field of laser cleaning, and has always adhered to the tenet of "green low-carbon, clean and efficient, and harmonious symbiosis". Shengtong has a complete set of quality system certifications. It has passed strict international, European Union, and factory certifications to ensure the stability of each equipment without any worries, including research and development software, cleaning gun heads, and lasers. Now it has independently developed and produced ultra-high-power 6000-watt laser cleaning equipment, which has reached the international advanced technical level. It can perform rust removal operations on difficult-to-handle parts of rail transit, and can also realize cleaning light source adaptive rail arc surface, green environmental protection, no damage to the substrate. It can be widely used in rail transit and other fields to clean rust layer dirt and paint surfaces, including train wheelsets, brake beams, bogies, and local inspection before cleaning. Now it owns two laser brands and four holding companies, "Shengtong" and "Chengjing". It has a number of core R & D personnel from Tsinghua University, Chinese Academy of Sciences and other famous institutions. It has obtained 53 national Expanding to more sophisticated fields, contributing more to the high-quality development of rail transit. Today, with the rapid development of laser cleaning, the company has formed a modular, standardized, and integrated management model, enabling enterprises to move towards refinement, specialization, and high-end.

This time, Shengtong Intelligent Laser has brought high-end products such as laser cleaning series STQX-1200F, STQX-1350S, STQX-1500S, STQX-16000S, and automatic cleaning robots. These laser cleaning equipment has been widely used in train wheel pair cleaning, train rail rust removal, train brake beam cleaning, etc. Laser cleaning equipment can achieve single-person operation or cooperate with robot integration work, avoiding additional applications for railway transportation plans, further providing work efficiency, and saving millions of labor costs and consumables costs for customers every year.

Time flies, the three days of the exhibition are crowded with the booth, in full swing, customers have direct needs, there are also joint research and development, and some also take the samples that their company needs to clean to the scene for proofing, all kinds of problems The consultation is in full swing, seeing the satisfied smile of customers, every employee of Shengtong is very gratified! Looking forward to our meeting in 2022 and empowering the future for the development of China's rail transit!
