Create the Chinese's own shield

Li Gang, a special technician of China Railway Equipment Shield Company. In 2003, it coincided with the "Shield Machine Experimental Simulation Platform" National 863 plan just settled in the company. As a most basic electrical worker, Li Gang began to intervene in the 863 plan of the "Shield Machine Simulation Platform". At that time, the domestic and foreign markets were monopolized by the "Yang Shield". The "Shield Machine Simulation Experimental Platform" was the starting plan for making domestic shields. Starting from the drawings, he sorted out the trend of each system and cables, and each connector was connected. From scratch, from strange to familiar, from familiarity to familiarity with his chest, he used this process for five years.

In 2007, the "Shield Machine Simulation Experimental Platform" passed the acceptance of the National 863 Program expert review team. Subsequently, he devoted himself to the manufacturing of the first domestic shield to be responsible for the electrical system of this shield. The first shield in 2008 was smoothly offline and applied to the construction of Tianjin Metro. This is the first time that domestic shields have been used for "actual combat". The prelude. At present, the shield orders of China Railway equipment have already been ranked more than 1,300, becoming a "fist product" that sells worldwide, and Li Gang is the electrical system "trader" of these equipment.

Workers also have to innovate

Since joining the work, Li Gang has been engaged in the work of shield machine electrical systems and participated in the process of witnessing the domesticization of the shield machine. He deeply understands the importance of independent innovation.

"Don't think that technological innovation is just a matter of designing research and development and technical personnel. As a front -line worker, we also have a lot of jobs to do in innovation." Li Gang not only educated employees in the education workshop, but also practiced.

In the "China Railway 37" shield project, in order to ensure the smooth progress of debugging, Li Gang proposed that the 275KW motor used the solution to use the antihypertensive conditions of 400V and 29Hz, which solved the debugging problem. The successful application of motor antihypertensive is a breakthrough in the domestic and foreign electrical industries, creating conditions for the factory debugging of the product.

In November 2013, the world's largest rectangular shield "China Railway 88" was applied to the construction of tunnel construction under the Zhengzhou Metro Zhongzhou Avenue construction. During the debugging process, the problem of communication interference was encountered. Li Gang led the team members to conduct repeated experiments and proposed a solution to the communication interference problem by increasing the wound coil filtering and removing miscellaneous waves.

Optimize the wiring box wiring method, fix the sensor with a tube card on the roller of the belt, design and make the wiring workbench workmade ... Behind these technological innovation, Li Gang and his team can always be seen.

Big country craftsman's reputation

After more than 30 years of electrical fighting, Li Gang's technology and theory have been improved. He has been hailed as the top shield machine electrical trader in China. After a century of monopoly foreign companies, the performance has jumped in the world's first, and has been unanimously recognized by leaders and colleagues in the field of electrical professionalism.

In May 2017, Li Gang's Great Power Craftsman Studio was established. It successively carried out nearly 30 topics and technical innovation projects, and obtained more than 10 practical patents. He successively trained 3 electrical senior technicians, more than 10 technicians, and more than 50 senior workers.Names, cumulative cultivation of nearly 400 shield electrical technicians, has strongly strengthened the company's electrical design and assembly talent teams.He has also won the "China National Railway General Trade Union Medical", "Henan May 1 Labor Medal", "Henan Young Craftsman", "Henan Provincial Technical Experts", "Top Ten Experts in China", "China Railway Outstanding Communist Party Members" and so on.The honorary title and enjoy the special allowance of the State Council.With a diligent and pragmatic attitude, the pioneering energy of innovation, and a meticulous dedication spirit, he worked hard in the development and production positions of the electrical systems of tunnel equipment, and will be persistent and unrequited.Essence
