01.Track operation and maintenance equipment
After years of field practice and several iterations of upgrading, Tianjin Santroll has developed the third generation equipment with mature technology and stable performance, and applied for invention patents. The equipment adopts metal atom fusion technology to realize the welding of the contact wire joint, which can realize the precise docking of the broken wire. After the welding, the excess mother material will be automatically removed, and the mechanical and electrical properties will remain unchanged. The equipment has carried out welding tests for many times and in many places, and the tests of key parameters such as mechanics and electricity of the welded samples all meet the requirements of the national standard TB/t 2809-2017, which has the conditions for commercialization.
The intelligent welding equipment greatly reduces the operating unit's operating costs, solves the industry's pain points in the overhead contact system wear management, uses the online welding breakpoint connection process to replace the whole anchor section wire change, truly realizes the targeting, targeted management of weak links, and realizes the optimization of the wire change mode. Taking Tianjin Metro Line 5 as an example, the entire anchor section 360 meters wire change cost is about 144,000 yuan. The breakpoint is used to continue the local wire change process, assuming that the wire change point is the intermediate point, the maximum wire change point is only 180 meters, the maximum cost of the contact wire change is more than 72,000 yuan, and the cost of each anchor section change can save at least 72,000 yuan. According to the existing wear state, the average annual replacement of 8 anchor sections for each operating wire can save at least 576,000 yuan per year. In the comparison of economic benefits, it has a high value of application and promotion.
02.Contract cooperation
Recently, Tianjin Santroll and Tianjin Railway Power Supply Co., Ltd. successfully signed a cooperation agreement. The signing of the agreement marks a new stage in the research and development of contact wire breakpoint connection equipment and process research, and Santroll's advanced welding technology and pioneering industry solutions have been further recognized.
Before the signing ceremony, the two sides reviewed the process of research and development of the breakpoint connection process since the cooperation of the subway project, and affirmed the stage results achieved. Subsequently, in-depth exchanges were conducted around the pain points and difficult problems of the rail transit industry. The two sides agreed that through cooperation, they can give full play to each other's advantages in application scenarios and technical research, and achieve mutual complementarity and win-win. In the future, the two sides will continue to deepen cooperation achievements, broaden cooperation areas, and create a new situation of win-win cooperation.
03.Intelligent operation and maintenance Forum and academic conference
Previously, Tianjin Santroll brought intelligent welding equipment for rail transit contact wire to the 8th International Academic Conference on Smart City and Rail Transit, and demonstrated Santroll's advanced welding technology and pioneering industry solutions to rail transit industry leaders, technical experts, and academic elites through live demonstrations, which received wide attention and praise.
In the intelligent operation and maintenance forum, Tianjin Railway Power Supply Company made a theme report on the "Research and Application of breakpoint connection process of traction power supply contact wire System", and Tianjin Pine was on the spot welding demonstration.
04.Expert Review
Jointly organized by Tianjin Santroll and Tianjin Power Supply Company, the "Contact wire breakpoint connection process hanging effect Review meeting" was held in Tianjin Santroll.
Tianjin Santroll and Tianjin metro related leaders participated in the review meeting, and also invited five senior experts in the rail transit industry to attend the meeting. With rich professional knowledge and practical experience, the experts conduct strict evaluation on the research results and technological innovation of participating enterprises.
During the review process, the key issues were discussed in depth to ensure the fairness and fairness of the review results. During the evaluation process, the welding process was demonstrated in the Tianjin Santroll workshop.
Finally, the following conclusions are given:
1. The contact wire breakpoint connection equipment welding fine, high degree of automation, welding contact wire in line with the industry specifications, for the industry's first.
2. Second, the contact wire cold press welding breakpoint connection process is scientific and reasonable, to meet the quality and construction efficiency requirements of rail transit contact wire, and the cost reduction effect is significant.
3. The equipment and process have been tested and verified in Tianjin Railway with good results.
Tianjin Santroll will continue to use scientific and technological innovation to empower the new quality productivity of rail transit, adhere to innovation-driven development, strengthen industry cooperation, and constantly explore new processes and new means to provide continuous power support for the high-quality development of rail transit.
