Hunan construction machinery industry to speed up the intelligent upgrade, the stability of the aerial work platform to enhance--

42 meters high up and down, not a drop of water in the cup (new economic orientation, transformation and upgrading of traditional manufacturing industry)

Reporter Shen Zhilin "People's Daily" (02nd Edition, May 29, 2024)

General Secretary Xi Jinping emphasized that "the manufacturing industry is the foundation of our country and the foundation of a strong country" and "promote the high-end, intelligent, and green development of the manufacturing industry".

Traditional manufacturing industry is the main body of China's manufacturing industry and the base of modern industrial system. The added value of traditional manufacturing industries such as steel, non-ferrous metals, machinery, and textiles accounts for nearly 80% of the total manufacturing industry, which is an important foundation for supporting the development of the national economy and meeting the needs of people's lives.

In recent years, in order to promote the transformation and upgrading of the traditional manufacturing industry, various regions and departments have made practical efforts, made practical moves, and sought practical results. The business entities of various industries have also accumulated a lot of good ideas, good experiences, and good practices. Recently, our reporter entered the factory, went to the workshop, and explored the production line to see how the traditional manufacturing industry can enhance new momentum and burst new vitality in the transformation and upgrading.

Lifting, translation, rotation, drop... In just a few minutes, Hunan Xingbang Intelligent Equipment Co., Ltd., a high-meter arm car work bar, in the 42-meter altitude up and down a back and forth.

"Look, a glass full of water, not a drop spilled." Pick up the water cup just placed on the work bar, said Luo Shiqiang, chief engineer of Hunan Xingbang Group Technology Research Institute, the parent company of Xingbang Intelligence.

For aerial work platforms, the slight shaking on the ground may be magnified several times or even dozens of times at an altitude of tens of meters. Stability and smoothness are the key to product quality, but it is not easy to improve.

"Large orders cannot be taken in a hurry, and overseas markets cannot enter." A few years ago, Xingbang Intelligence faced a dilemma: its innovation ability was not strong enough, its production process was not refined enough, and its production efficiency and product quality did not have many advantages compared with peers.

Under the pressure of competition, Xingbang Intelligence is determined to transform to automation and digitalization.

The difficulty is far greater than imagined. The research talent reserve is insufficient, and it is impossible to solve the problem of end-to-end data connection in each link.

Xingbang Intelligence found an industrial digital transformation service provider, and only after consulting did it know that the transformation needs the corresponding software to support the system.

Every task of transformation is urgent: purchase complete sets of digital software and build a digital management system; Change thinking and improve management's digital concept; Step up training of digital engineers in practical skills......

With the help of service providers, the enterprise will start from scratch and adapt step by step. The second phase of factory construction will be completed in 2020, initially realizing the digitization of the production process, the background data can be traced back to the source, and the product quality will be greatly improved.

The massive data of product application is a huge resource pool, but it is necessary to wake up the precipitated data resources so that product development and production can be targeted, which is beyond the scope of the previous service provider's ability.

What to do? This time, Starband Intelligence decided to do it on its own, setting up and expanding its corporate research center. During this period, enterprises found that digital software to better serve the construction machinery industry, service aerial work platform products, generally need secondary development, for specific application scenarios to optimize.

In the face of technological gaps, enterprises actively make up for the shortcomings of innovative talents, expand the Ministry of Information Technology into a Smart Research Institute, and increase the number of personnel from a few to dozens. Under the joint force, the hard bones in the intelligent process are gnawed down by 1.1 points. Take production line control as an example, the first thing to be solved is the data upload and application of each production link. For example, the setting of the tightening torque of each screw is accompanied by data upload analysis and process adjustment, and the fineness can be seen.

In 2022, the fourth phase of the plant will be completed, and more innovative results will appear. On the digital production line, in the detection and calibration sorting station, the handling robot grabs the rectangular tube that has just been welded and places it in front of the laser detection equipment to complete the ranging and hydraulic calibration at one time to ensure that the welding straightness is always controlled within 1mm-the accuracy is nearly 10 times higher than that before the transformation. In that year, Xingbang Intelligent's operating income was close to 2.6 billion yuan, up nearly 37% year on year. In 2023, the company won the top 50 construction machinery manufacturers in the world.

As one of the main suppliers of Xingbang intelligent non-metallic parts, Changsha Zhongjing Machinery Co., Ltd. receives a new version of the technical standard from the host company almost every year. "The pace of transformation and upgrading of leading enterprises has accelerated, forcing supporting enterprises to keep up quickly." Enterprise general manager Chen Xingyu said.

For example, according to the new standard, the solid rubber tires of aerial vehicles produced by Zhongjing Machinery are not consistent and stable enough. Enterprises have found a number of domestic colleges and universities to demonstrate the feasibility of the theory, and then repeatedly test the practical application.

Investment in research and development needs money. Zhongjing Machinery has filled in all the funds awarded by the provincial enterprise technology center and the special funds for the development of small and medium-sized enterprises. Finally, it has invested more than 600,000 yuan to develop new equipment, which can control the vulcanization and molding temperature of rubber tires. As a result, each batch can build 8 tires, each tire has higher consistency and more stable performance.

In order to support the construction machinery industry to accelerate the intelligent transformation and digital transformation, Hunan has issued special fund management measures for the development of small and medium-sized enterprises, promoted the identification of provincial enterprise technology centers, and a number of measures encourage the formation of a scale effect of "upgrading one leading enterprise and driving one transformation supporting enterprise.

"With the improvement of intelligent supporting capabilities for Xingbang, we are now entering the supply chain system of Zoomlion, Guangxi Liugong, Sany Heavy Industry, Xugong Fire and other enterprises." Wu Zhong, general manager of Changsha Changheng Intelligent Technology Co., Ltd., said that at the end of last year, the company initially realized the digital management of the whole process of product processing, and the detection rate of a defective product produced dropped from five ten thousandths to one ten thousandth.

The improvement of stability and ride comfort is the epitome of the systematic transformation and upgrading of Hunan aerial work platform production enterprises. At present, Hunan is focusing on this advantageous industry, strengthening the reconstruction of the industrial foundation and tackling key problems of major technical equipment. Many aerial work platform enterprises are making efforts in the development direction of lightweight products, heavy load, low energy consumption, precise and intelligent control, and have made certain breakthroughs.
