The manipulator grabs the rib plate and accurately stands it on the cover plate of the main beam of the crane, and sparks ...... at the jointLocated in the production plant of Xinke Crane Co., Ltd. in Changyuan City, the automatic production line is operating in an orderly manner.
You see, with fully automatic production equipment, one-button operation is all it takes. Cai Cunchao, a worker who was operating the equipment, told reporters.
Through the application of this set of welding equipment, the welding efficiency of the crane girder has been increased by nearly 3 times. Cai Xiaojie, the person in charge of the company, introduced on the side that this set of equipment was independently developed by the company and applied for a patent. In recent years, through continuous innovation, ST has continued to increase crane orders, and the total number of orders in 2023 will reach 3,500 units.
In addition to innovation in production, local crane companies are also constantly advancing in the research and development of new products.
A crane often weighs hundreds of tons, and the spreader shakes greatly during the operation
Walking into the experimental testing center of Weihua Group, Shan Yingge, an engineer of the electrical R&D department, was standing on a simulated crane with his colleagues for experimental operations. "By continuously optimizing the anti-sway technology, the team is working on a closed-loop anti-sway system, which is expected to achieve real-time anti-sway of the crane in a variety of environments by automatically detecting and reducing the dynamic interference of the external environment. Shan Yingge said.
Since 2006, Weihua Group began to develop the electrical anti-sway technology of the crane, and finally successfully realized the independent research and development of the anti-sway accurate automatic positioning control technology. With the continuous improvement of technology, the swing amplitude of lifting equipment is now reduced by more than 95%, which is at the leading level in the world.
We spend 4% to 6% of our annual sales revenue on product research and development, the company has more than 1,400 authorized patents, and the group will invest more than 800 million yuan in R&D in 2022. Han Hongan, chairman of Weihua Group, said.
Taking technological innovation as the starting point and new product research and development as the kinetic energy, accelerating product iteration has become an important measure for the development of the crane industry in Changyuan City. The local government continues to support enterprises to build provincial and above key laboratories, technology innovation centers and other R&D institutions, 70 enterprises have been recognized as national high-tech enterprises, and 2 enterprises have been rated as "head goose enterprises" in the provincial manufacturing industry.
Build a service platform.
Improve the industrial chain.
The unattended crane can be put into production and landed, and the first platform is the key. Han Zhaopeng, vice chairman of Giant Group, said.
According to reports, the Lifting Equipment Expo Fair, sponsored by the Changyuan Lifting Equipment Manufacturing Industry Association and undertaken by the Management Committee of Changyuan Economic and Technological Development Zone, has been held for 8 consecutive sessions. Han Zhaopeng said that through the exhibition, Changyuan City actively promoted the cooperation between Giant Group and foreign technical teams to develop unattended cranes, and also provided opportunities for foreign markets to fully understand the company's products.
Walking into the factory building of Giant Group, Han Zhaopeng pointed to a small screen on the lifting equipment. "Don't look at this lifting overload limiter as inconspicuous, its role is crucial. "Once the crane is overloaded, the lifting overload limiter will immediately cut off the power supply to ensure the safety of equipment and personnel." ”
How to purchase supporting equipment?The reporter asked.
Two kilometers away is Hengda Electromechanical, and now the supporting equipment can be purchased in the park, which is very convenient. Han Zhaopeng said.
The park mentioned by Han Zhaopeng is a professional park for lifting equipment. In March 2022, Changyuan Economic and Technological Development Zone introduced manufacturers of supporting equipment such as lifting overload limiters and reducers to invest in the construction of factories, building the park into a hoisting machinery manufacturing base with a high degree of agglomeration and a complete chain.
We came to Changyuan to invest in the construction of a factory, what we like is the agglomeration benefit of the industrial chain here, in the park, we dig deep into the products, so that the products can be delivered to the downstream production enterprises on the same day. Xu Jin, head of Henan Hengda Electromechanical Equipment Company, said.
Up to now, in addition to plates, more than 20 types of products involved in crane production have supporting production enterprises in the lifting equipment professional park, including 126 main beam manufacturing enterprises, 15 reducer production enterprises, and about 150 motor production enterprises. The park has formed a relatively concentrated layout, products supporting each other, from design, manufacturing to installation, after-sales of a relatively complete lifting industry chain.
Promote cross-border integration.
Accelerate the implementation of applications.
Scan *** Select the parking space code, the three-dimensional parking lot starts to operate, and in less than two minutes, the empty parking space comes to the front. The intelligent three-dimensional garage of Changyuan People's Hospital covers an area of 882 square meters, providing more than 300 parking spaces, designed and built by Weihua Group.
In the past, crane equipment was mostly used in the industrial field, and we have been exploring more life application scenarios. Liu Yonggang, chief engineer of Weihua Group, introduced that mechanical parking equipment belongs to the lifting machinery sub-project, the technical principle is the same as the crane, Weihua Group through the integration of existing technical resources, to promote cross-border integration in different fields.
Latent A** (automatic guided vehicle) equipment is an intelligent handling robot independently developed by Weihua Group, with a single product of the equipment that can carry 1000 kg and run at a speed of 1 per second under load2 meters, mainly used for the transfer of whole pallet goods and whole piece picking. "Handling robots and cranes belong to the same category of special equipment for lifting, and we will integrate crane manufacturing technology into robots to finally realize the application of logistics scenarios. Liu Yonggang introduced.
Under the guidance of digitalization and intelligence, the crane industry has achieved joint development with multiple industries, and more lifting equipment has also achieved multi-functional applications in emerging scenarios.
Guide the new energy heavy truck to stop accurately at the designated position of the battery swap station, start the battery swap robot, grab the battery and put it into the charging slot, and then grab the fully charged battery and load it into the truck, and in less than 5 minutes, the new energy heavy truck completes the replacement of the battery pack. In the past, it took five or six hours for a new energy heavy truck to be fully chargedNow, with an unattended battery swap station, battery swapping can be completed in no time. "No more mileage anxiety!Zhang Baojun, a driver who came to Xinke to pull goods, said.
Once, in the process of communicating with new energy heavy truck drivers, Cai Xiaojie found that drivers are often accompanied by range anxiety when driving, but the new energy heavy truck battery is large in size and heavy in weight, which is extremely inconvenient to carry. After a year of hard work, ST has developed a heavy-duty truck battery swapping station, which integrates heavy-duty truck charging equipment with intelligent lifting robots to achieve efficient and convenient battery replacement.
The heavy-duty truck battery swap station is suitable for short-distance transportation and other scenarios in ports, mines and other industries, and the battery swap station realizes autonomous obstacle avoidance, automatic lifting and precise positioning of the lifting robot through the perception equipment and intelligent control system, and finally realizes the automatic unmanned replacement of the battery, which alleviates the user's mileage anxiety.
We will continue to comply with the development trend of deep automation and intelligence of logistics, broaden the application field of the crane industry, develop new application scenarios such as automatic conveying and sorting systems, vertical circulation and other types of three-dimensional garages, and continuously improve the competitiveness of the industry.
