Technical Services/Products

This technology is a new type of integral insulated platform door technology independently developed by our institute, which researches the basic theory of platform door insulation connection, insulation deterioration mechanism, stray current protection and other key technical issues, and puts forward the concept of eliminating the connection line, and adopts the co-extruded molding process of composite insulating material and steel structure to realize the main structure of the platform door, under the premise of not changing the appearance, installation mode and use function of the platform door. Integral insulation. Developed a series of new overall insulated platform door technology and equipment, to solve the current urban rail transit platform door system commonly exists in the insulation index is difficult to reach, poor durability, fire, stray current protection and other related to passenger safety, affecting the level of subway service of the industry's pain and difficulty. The technology has successfully passed the evaluation of scientific and technological achievements led by academicians, and the evaluation concluded that it is at the international advanced level, and it has been granted one authorized invention patent, two authorized utility models, two provincial awards and one municipal award.

Technical features and advantages/innovations

(1) Realizing the fundamental change of the concept of platform door insulation and rail connection, and laying the foundation for opening up the technical line of not connecting the platform door with the train;

(2) The use of composite insulating materials, such as extrusion molding process, to achieve the integration of the platform door door body of the overall insulation;

(3) superior insulation performance, according to third-party test data, the average value of the measured insulation of the platform door is not less than 4MΩ, which is much larger than the target requirement of 0.5MΩ;

(4) Superior mechanical properties, according to third-party test data, the deformation of the composite material column, door frame and threshold is reduced by more than 18% compared with the traditional platform door;

(5) Excellent durability, the life of the new integral insulated platform door can be up to 30 years, which is much larger than the life of 5~8 years of the traditional technology such as surface insulation spraying or filming;

(6) It has the advantages of simple operation and maintenance, not affecting the overall appearance, and simple construction process, etc. Estimating the full life cycle of the platform door, it can save about 160,000 RMB per station per year.

Applications/Scenarios

According to incomplete statistics, part of the results of this scientific and technological innovation or the overall results have been successively in Guangzhou Metro, Shenzhen Metro, Beijing Metro, Hangzhou Metro, Zhengzhou Metro, Wuhan Metro, Montreal REM project (overseas) and so on more than 40 lines in 16 cities to promote the application of the project, and has achieved good economic and social benefits.

This scientific and technological innovation mainly applies to the urban rail transit platform door lines with DC traction power supply and rail return, and also applies to other insulated application scenarios that require integrally molded parts.
