1993, Luo dongyuan successfully developed the "fully automatic turnout device" based on the "JD-type vehicle turnout device", and put it into use on 1993, 165438+ 10. After more than six years of practice, the device has the characteristics of safety, high efficiency and stable performance. 1995 won the national patent in February, 1997 won the second prize of Guangdong heavy chemical industry department for scientific and technological progress in June,1997 won the Guangdong patent implementation excellence award, and1999 won the silver prize in the 12th National Invention Exhibition in September. The project signed a non-patented technology transfer contract of 200,000 yuan, which opened up a new road for the automation of a large number of railway decentralized turnouts in industrial and mining enterprises. 5. In the aspect of automation and modernization of railway transportation in Shaogang, Luo Dongyuan has made the greatest efforts, made the greatest contribution to scientific and technological achievements, and initiated a new type of electrical centralized system developed by him in industrial and mining enterprises, realizing the comprehensive and comprehensive large-scale creative development in this field of technological innovation.
Independently complete the design of large-scale and super-large-scale logic control circuits in operation areas and stations; Initiated "electronic turnout DC track circuit" and "electronic centralized safety track circuit"; Console, switchboard, power screen and other supporting equipment are also innovative designs.
During the period of 1994 ~ 1997, Luo Dongyuan applied his new electric centralized system in Sanjiao industrial and mining enterprise, low copper mine crushing area, rolling station, blast furnace iron water area and No.4 blast furnace area of Shaogang. The working surface of No.4 blast furnace of Shaogang is complex and very large, with 13 tracks and 78 sets of switches. This technology alone saved enterprises 9.26 million yuan in investment.
At present, there are more than 200 turnouts in Shaogang, and more than 180 turnouts have achieved electrical control, with a power-on rate of 90%, which is at an advanced level in industrial and mining enterprises. It not only created economic benefits, but also produced remarkable social benefits. Shaoguan Iron and Steel Co., Ltd. cancelled the switch machine for heavy and dangerous jobs, which not only greatly reduced the labor intensity, but also improved the labor productivity.
