Yi Xiaogang’s main contributions

He spent 15 years presiding over and guiding the development of 21 major series of products with more than 120 specifications, making breakthroughs in concrete pumping, ultra-long intelligent robotic arms, engineering machinery energy saving, high-speed railway slab ballastless track, etc. A number of key technologies have been used to develop a large number of world-leading core products. Sany concrete pumps, concrete pump trucks, concrete mixing stations, and asphalt cement mortar trucks have been built into the first domestic brand, with market share ranking first for many years. It broke the long-term technology and price monopoly of foreign concrete machinery and enabled domestic concrete machinery to go from being 95% dependent on imports to 95% localized in 1995. It led the technological progress of the entire industry and ranked first in the world in production and sales of concrete machinery, changing our country. Concrete machinery relies on imports and has set and refreshed world records many times.

He is Yi Xiaogang, chief engineer of SANY Group, dean of SANY Research Institute, and director of SANY Postdoctoral Workstation. Back in the spring of 1995, it was a beautiful season when hundreds of flowers bloomed and thousands of birds sang. Sany Heavy Industry, a private enterprise located in Xingsha Town, Changsha County, fell into trouble shortly after its establishment and entered the bottleneck stage of enterprise development. At that time, Sany Heavy Industry only had one product - the HBT60 towable concrete pump. Due to unstable technical performance and poor product quality, sales were in trouble and the company was struggling. In order to get rid of the company's predicament, Liang Wengen, chairman of Sany Heavy Industry, considered that professional and technical talents were the company's most lacking resource, so he spread hero posts across the country and recruited professional and technical talents from all directions.

In the spring and summer, Liang Wengen, who was eager for talent, went through all the trouble and finally found Yi Xiaogang, a hydraulic expert at the Beijing Institute of Machinery Industry Automation of the Ministry of Machinery Industry. Yi Xiaogang was born in September 1963 to a teacher's family in Wugang City, Hunan Province. After graduating with honors from Huazhong Institute of Technology (now Huazhong University of Science and Technology) in July 1985, he was given priority in the Automation Research Institute of the Machinery Industry in Beijing. work. When recalling his ten years of life at the institute from 1985 to 1995, Yi Xiaogang said: "Today's achievements are due to the selfless teachings of all the mentors and friends in the institute, and to the foundation laid in the institute. "There he participated in and presided over the development of injection molding machines, hydraulic pumping units and other projects, and won many awards from the Ministry of Electronics Industry and the Mechanical Science Research Institute of the Ministry of Machinery Industry. As the subject leader of one of the four sub-projects of the "Research on the Localization of Key Hydraulic and Pneumatic Components of 154-ton Mining Dump Trucks" project issued by the Major Project Office of the State Council, he was awarded by the Ministry of Machinery Industry and the Mechanical Science Research Institute of the Ministry of Machinery Industry respectively. Second Prize for Scientific and Technological Progress.

Show your skills in times of crisis and donate your blood to Trinity

In June 1995, Yi Xiaogang, who was ordered to face the crisis, came to Xingsha from Beijing alone, and Sany Heavy Industry, which was in trouble shortly after its establishment, worked together to reclaim wasteland. They live in a work shed built by migrant workers with cement tiles and work in a simple workshop with yellow mud under their feet. They are surrounded by loess and barren mountains. On sunny days, the face is covered with yellow sand, and on rainy days, it is difficult to sleep due to humidity. During the day, it is accompanied by mud, sand and oil, and at night, it sleeps with rats, mosquitoes, flies and crickets. During the start-up period, the company could not even afford travel expenses. Yi Xiaogang used his own funds for travel expenses. Liang Wengen was cruel and sold his 50,000 yuan treasury bills as working capital for the company's technological transformation. Yi Xiaogang, who was accustomed to having one computer at a time when working in Beijing, led twenty or thirty colleagues to use the company's only computer. When the computer needed repairs, they used calculators to calculate data.

From computer operation to "taking charge" of calculators, Yi Xiaogang didn't complain at all. Wearing thick work clothes and rain boots, he plunged into the construction site under the scorching sun. The work clothes got wet and dried. Dry and wet. Summer nights in the south are hot and humid, and mosquitoes abound. Often after a night shift, my whole body is covered in redness and swelling from mosquito bites. At that time, ordinary technicians worked in three shifts, but Yi Xiaogang, as the project leader, stayed at the debugging site day and night in order to see the results of his design as soon as possible. Later, the technicians around him couldn't stand it anymore and took turns using fans to drive away mosquitoes for him. It was under such conditions that Yi Xiaogang relied on his hydraulic expertise and solid foundation in machinery and control, and in the spirit of hard work and technical excellence, he completely transformed the mechanical, hydraulic and electrical systems of the concrete delivery pump. , and combined hydraulic technology with computer control to solve the problem of low pumping height at that time, ensuring the quality of the product, and the domestic market of Sany pumps was rapidly expanded.

As one technical problem after another was overcome, Yi Xiaogang felt that the summer was not that long. However, before he could take a breath, another new problem appeared in front of him. The concrete delivery pumps previously launched by the company can only meet the demand for lower-height pumping due to low pumping pressure. The market for high-pressure pumps is still monopolized by foreign products.

Yi Xiaogang was determined to develop a high-pressure concrete pump. It was the Spring Festival of 1996. His wife in Beijing missed him very much. She called him one after another urging him to go home for the New Year, and every time he came out of breath. When he rushes to the office to answer the phone from a construction site far away, he usually only has one sentence: "I'll be back soon!" Once his wife couldn't help but ask him: "Are you so busy that you don't have time to say a few words? " He held back the tears that were welling up in his eyes, silently put down the phone and went to the construction site again.

In October 1996, Sany Concrete Pump participated in a worldwide concrete pump field competition at the construction site of the new terminal of Capital Airport and won second place, second only to the German Elephant Pump. This not only marks that Sany pumps have won the market by relying on quality, but also marks that Sany Heavy Industry has emerged from the predicament, and at the same time enhanced the status of domestic pumps in the international industry.

However, Yi Xiaogang was not satisfied with the second place result. He simply regarded the construction site as his home and devoted himself to the project he was studying. Until one time, when his 3-year-old son cried and asked his mother to carry him to the company to see him because he missed his father, he put down the paper and pen in his hand and enjoyed his son's kiss.

In April 1999, during the on-site construction of Shenzhen SEG Plaza Building, Sany HBT80C concrete pump successfully pumped the highest construction height of 300.8m for domestic pumps, reaching the international advanced level and winning the "Pump Award" "King" reputation.

By the end of 1999, Yi Xiaogang had applied new technologies such as full hydraulic reversal of the pumping system, computer closed-loop control of diesel engine speed, and fully automatic high and low pressure switching to the concrete pump series, making the product a Products with the largest variety and complete specifications in China. Sany's towable concrete pumps have emerged rapidly, the share of imported products in the domestic market has dropped sharply, and the company's economic benefits have grown rapidly.

In November 2002, Sany ultra-high-pressure concrete pump set a world record of 406 meters vertical pumping by a single pump at the Hong Kong International Financial Center.

In September 2003, the concrete pump truck with Asia's longest boom of 56 meters was successfully rolled off the assembly line at Sany, marking that Sany has entered the world's most advanced level in the field of pump truck and boom research and development.

In January 2007, SANY successfully developed a pump truck with the world's longest boom of 66 meters, and successfully applied for the Guinness World Records in September of that year. The global tour was a great success

< p>In December 2007, Sany ultra-high-pressure concrete pump pumped 492 meters vertically with a single pump in the Shanghai World Financial Center, setting a new record again

In December 2008, Yi Xiaogang led his research and development The team once again challenged the powerful foreign brands, and the 72-meter-long boom pump truck in the world successfully rolled off the assembly line, once again refreshing the world Guinness record created by itself.

In 2010, it developed the world's first 50MPa ultra-high-pressure concrete pump, and assumed the world record of pumping concrete at a height of 632m in Shanghai Center.

On March 19, 2011, in response to Japan’s request for help, the 62-meter pump truck developed by the company rushed to the aid of Japan’s Fukushima Nuclear Power Plant. The maple leaves in Juzizhou are red and green, the water of the Xiangjiang River is mighty and rushing forward; through the dense jungle of Yuelu Mountain, there is a broader world! Adhering to the principle of "everything comes from innovation", Sanren, under the leadership of Yi Xiaogang, has "boosted" China's construction machinery with its innovative spirit of daring to be the first in the world.

In the Chinese pump truck market in the late 1990s, Chinese companies could only produce short-boom pump trucks under 32 meters long. The long-boom pump truck market was all occupied by foreign brands. Dare to be the first in the world. Yi Xiaogang is determined to develop a world-class concrete pump truck.

In April 1999, Yi Xiaogang successfully developed my country's first 37-meter concrete pump truck with independent intellectual property rights. The core component of the concrete pump truck is the boom. Since China did not master the key technology for developing booms at that time, booms over 37 meters had to be imported. Domestic colleagues have a famous saying, "It is more difficult to extend the boom by one meter than to reach the sky." At that time, no one in the domestic colleagues dared to think that the Chinese could make the boom themselves.

"The Chinese must develop their own boom."

His mind was filled with jibs. Once, he almost caused a disaster because he was too focused. That day, he drove out by himself to search for information. On the way back, he was only thinking about how to solve the load and vibration problems of the arm. He completely forgot that he was still driving. He took his hands off the steering wheel to indicate the scale and distance. As a result, the car crashed into the car. on the roadside fence. Fortunately, the speed was relatively slow, and apart from the car being damaged, no one was injured.

After five months of struggle, Yi Xiaogang finally successfully developed a 37-meter jib designed by the Chinese. In November, the pump truck assembled with this boom was put on the market and won recognition from users and society.

Since then, Yi Xiaogang has led his R&D team to continuously launch long-boom, high-pressure, and large-displacement concrete pump trucks. In March 2001, SANY developed the 48-meter boom, the longest boom in China that year, marking that my country was in sync with internationally renowned manufacturers in the field of pump truck and boom research and development.

In September 2003, the concrete pump truck with Asia's longest boom of 56 meters was successfully rolled off the assembly line at Sany, marking that Sany has entered the world's most advanced level in the field of pump truck and boom research and development.

On October 3, 2003, shortly after the 56-meter pump truck came off the assembly line, President Hu Jintao inspected Sany. He also sincerely sent a message to Sanyin: "You have achieved a glorious past, and I hope you will work together to have a better future." Yi Xiaogang led his R&D team, keeping in mind the instructions of the party and state leaders, and worked hard with a hundredfold improvement. Enthusiastically devoted to the great mission of innovative development and revitalizing national industry.

In January 2007, SANY successfully developed a pump truck with the world's longest boom of 66 meters, and successfully applied for the Guinness World Records in September of that year. The global tour was a great success.

In December 2008, Yi Xiaogang led his R&D team to once again challenge the powerful foreign brands. The 72-meter-long boom pump truck in the world successfully rolled off the production line, once again setting a new world Guinness record created by himself. .

On March 19, 2011, in response to Japan’s request for help, the 62-meter pump truck developed by the company rushed to the aid of Japan’s Fukushima Nuclear Power Plant.

Yi Xiaogang leads his R&D team to "boost" China's construction machinery with fearless innovation. "A pump truck costs more than 3 million yuan, which is simply unaffordable. If we want to cooperate in technology, others will look down upon us. Without independent innovation, companies cannot survive, let alone develop. This is how our technological innovation is forced came out". When talking about Sany when it started, Yi Xiaogang said realistically.

At that time, 95% of China’s concrete machinery products were imported. As a private enterprise, Sany Heavy Industry is in even greater difficulty. Due to poor quality and a large backlog of products, the situation is extremely severe.

As soon as Yi Xiaogang arrived in Changsha, he began to think about concrete delivery pumps (also known as tow pumps). In order to avoid technical barriers, Yi Xiaogang changed his mind and found another way. "When others use special parts, we use general parts, and then carry out technical improvements and integration on this basis."

When switching between high and low pressure, the concrete drag pump needs to switch to different pipes. Yi Xiaogang boldly designed a valve that could rotate 90 degrees. Unexpectedly, it encountered unanimous opposition from workers to workshop directors: Pipes are used in foreign countries, and customers have not raised any objections. How can it be replaced? In the end, it was Chairman Liang Wengen who made the decision to support Yi Xiaogang. Finally, a hydraulic manifold valve group with a completely different working principle from the original product was designed. The company's first patent was born.

“This is not a difficult breakthrough, it is just a change of thinking.” Yi Xiaogang said bluntly. Abandoning the conventional path of imitating foreign product design, but boldly innovating on the basis of existing domestic and foreign technologies, this is the secret weapon for Sany Heavy Industry to succeed unexpectedly. "Some people shrink back every day, as if innovation is far away from us. In fact, this is not the case." Yi Xiaogang said. In his view, this fear of foreign technology actually stems from a lack of correct understanding of "innovation" itself.

When discussing technical issues, there are two sentences that Yi Xiaogang does not allow technicians to say: one is "This is done abroad, and we do the same", and the other is "This is not done abroad. Even if we have done it, we can’t do it.” Yi Xiaogang would also ask: "Foreign countries are wrong, are you also wrong?"

"If I have any contribution to our team, it is to continue my innovative thinking." Instill it into our R&D team of more than 8,000 people, and then work with my R&D team to continuously break through technology and solve problems one by one," Yi Xiaogang said.

"Innovation is a culture, a concept, and a courage. In other words, everyone can innovate." This is what Yi Xiaogang understands as "innovation", and it has now become a The creed of a scientific research team.

It is precisely by virtue of this unremitting technological innovation that Sany has not only won dignity for China, but also driven the development of the entire industry.

In March 2011, the 62-meter pump truck developed by Yi Xiaogang rushed to the aid of the Fukushima Nuclear Power Plant in Japan. During the entire water injection operation, the 62-meter pump truck played an irreplaceable role. Tokyo Electric Power Company highly praised the outstanding performance of the Sany pump truck, saying that it "played a very important role." Some Japanese personnel even affectionately called the Sany pump truck "the big giraffe." Sany has thus become a business card of China. Sany Heavy Industry's outstanding performance in international rescues has enabled Chinese manufacturing to begin to tear off the labels of "low price" and "low quality", greatly enhance the international image of "Made in China", and begin to expand its market share in machinery that has been monopolized by Europe and the United States for a long time. The manufacturing industry holds up the Chinese flag. Tan Jianrong, academician of the Chinese Academy of Engineering, spoke highly of Sany: "It not only leads the development of pump truck technology, but also leads the development of independent innovation in our country's entire equipment manufacturing industry." Academician Pan Yunhe, vice president of the Chinese Academy of Engineering, personally painted his calligraphy in Changsha The work "Technology Creates Sany, Quality Changes the World" was presented to Yi Xiaogang. This is not only an affirmation of the quality of scientific and technological innovation of Sany Group, but also a sincere appreciation for the unremitting innovation of Yi Xiaogang, a technology leader in scientific and technological enterprises.
