Speaking of excavators, everyone is familiar with them. But which company has the best excavator technology? I'm afraid not many people really know.
is 23.5 meters high from the caterpillar to the top, as high as an 8-storey building; it weighs 2,000 tons, and after all parts are disassembled, 40 train skins need to be installed; the huge bucket used for digging is enough to accommodate 300 people. This unique "Big Mac" in the world was developed and manufactured by Taiyuan Heavy Machinery Group Company.
Seizing the wave of industrial digital intelligence, Taizhong Group, which started with the word "heavy", is accelerating reform and innovation. It is installing "intelligent brains" and "sharp eyes" on these "big guys" and attaching a new label of "smart". The reporter recently visited Taizhong Group and experienced the power of "intelligent manufacturing" of industrial heavy equipment.
Make large machinery "alive"
Whether it is an excavator or crane weighing thousands of tons, a wind turbine with an impeller diameter of more than 180 meters, or a high-speed rail wheel pair traveling around the world... As the foundation of my country's basic industry, heavy machinery The importance is self-evident.
In 1950, when the national industry was in dire need, the central government invested 750 million kilograms of millet to design and build the first heavy machinery factory in New China in Taiyuan, Shanxi. Over the past 70 years, Taizhong Group has created more than 500 firsts in China and the world. It is my country's largest production base for lifting equipment, the largest excavation equipment, and the largest space launch device production base.
Walking into the steel jungle-like equipment factory, the majestic power of industrial heavy equipment hit us. In the past two years, more and more "big guys" have gained "great wisdom".
In the south open-pit coal mine located in Huolingol, Inner Mongolia, in the clean and bright remote cab, six high-definition screens displayed coal mining scenes in real time. The mining driver Wang Yongsheng slowly pushed the handle, and a large excavator excavated a few kilometers away. Coal, loading, and a mining cycle can be completed in half a minute. The "Big Mac", which is more than 20 meters high, looks light and agile on the screen.
's remote "one-click coal mining" allows open-pit coal mining drivers to bid farewell to the dusty working environment and transform from "black collar" to "white collar". Yue Haifeng, deputy director of the Mining Institute of Taizhong Group Technology Center, said that the 5G smart excavators developed by Taizhong Group have been put into use in three coal mines, and there are more than 10 orders on hand.
Similar changes have also occurred in coking, steel and other industries. More than a month ago, the intelligent coking equipment developed and produced by Taizhong Group was officially put into use at Jinnan Iron and Steel Group, realizing "one-click coking". Wang Fenfen, driver of the coke push truck, said that the original cab temperature was close to 40 degrees Celsius, and he could barely sit still with the help of two air conditioners. After the intelligent coke oven equipment was put into operation, she sat in the operation room of the centralized control center and could automatically complete the entire process of coal loading, coke pushing, coke blocking, coke receiving, and coke quenching with a tap of her fingers.
"From focusing on hardware to focusing on both software and hardware, by integrating the most advanced sensors and intelligent decision-making systems, large machinery weighing hundreds of thousands of tons comes to life, which not only provides users with more convenient services, but also Optimizing equipment in massive data and ," said Wang Hongru, director of the Intelligent Institute of Taizhong Group Technology Center.
Holding the core technology in hand
Taizhong Group shoulders the historical mission of creating a powerful country. It has created brilliance and experienced hardships.
"Before 2004, we cooperated with a foreign company to produce large excavators of more than 20 cubic meters. However, during the 20-year cooperation period, we did more than 80% of the work and only received 20% of the money. , It gradually evolved from the initial partner to the other party's wage earner because it did not master the core technology," Yue Haifeng said.
From the birth of the 10 cubic meter excavator to the birth of the 20 cubic meter excavator, Taizhong people have gone through a long 24 years. After mastering the core technology of super-large excavators, Taichuang excavators have completed the leap from 20 cubic meters to 75 cubic meters in just a few years.Today, Taizhong Group is one of only three large excavator manufacturers in the world. With the characteristics of durable equipment and high output, its domestic market share has been almost 100% in the past two years.
Five or six years ago, Taizhong Group’s train wheel set products once encountered a market decline. Some management problems in the past few years have also forced this state-owned enterprise into a situation where it urgently needs to get out of trouble and survive.
During the trough period, Taizhong Group turned its blade inward, worked hard to practice its internal skills, continuously broke the foreign technology monopoly, seized the opportunities of the "One Belt and One Road" construction, and obtained admission tickets as a supplier of high-speed rail core components. Today, Taizhong Group produces a wheel in less than a minute, and its products are exported to more than 60 countries and regions around the world, with exports accounting for more than 50%. Since the beginning of this year, the export of Taizhong wheel and axle products has increased significantly, with exports in the first five months increasing 2.5 times year-on-year.
tackles key core technologies and firmly holds the initiative of development in its own hands, which has become the winning weapon for Taizhong Group to transform and reborn again and again and return to the center of the world manufacturing stage.
continues to surpass
on the track of innovation. "The scale of excavators from small to large is by no means simply enlarged." Yue Haifeng said that a 10 cubic meter excavator weighs 500 tons. If scaled up in the same proportion, the weight of a 70 cubic meter excavator will be Reaching 3,500 tons, this will cause the equipment to be overweight and affect practicality. The actual product is 2,000 tons lighter than this value, which means that technicians have to optimize and upgrade more than 10,000 parts one by one.
"Take the control system we conquered as an example. After switching to AC frequency conversion technology, digging a ton of coal only consumes 0.18 kilowatt-hours of electricity, and the cost is reduced to one-seventh of that of a diesel excavator." Yue Haifeng said that in the era of intelligence, Next, we need to overcome the problems of continuous operation of intelligent heavy equipment and multi-equipment collaboration.
Innovation is always the life of an enterprise. Han Zhentang, Secretary of the Party Committee and Chairman of Taizhong Group, said that we should regard innovation as our mission, regard innovation as life, and strive to innovate as hard as we can. Under the system rules of fully doing front-end market research and technical feasibility research, , plan and subvert Innovate creatively.
focuses on key technologies such as "stuck necks" and upstream and downstream industrial chains. Taizhong Group relies on the State Key Laboratory and the industry-university-research cooperation platform to implement mechanisms and systems such as "unveiling the list", performance evaluation of R&D investment, and sharing of rights and interests of invention results. Innovate the shared employment model and promote the steady growth of corporate R&D investment intensity.
Technological innovation promotes efficiency improvement. Despite the impact of the epidemic, Taizhong Group's operating performance last year was still the best in recent years; operating income in the first quarter of this year continued to grow compared with the same period last year, total profits increased by nearly 20%, and the high-quality development of and was steadily advancing.
