recently, Hunan Science and Technology Award and Innovation Award conference was held in Changsha, The scientific and technological workers and innovation practitioners who have made outstanding contributions to promoting the innovative development of Hunan Province will be commended. Du Jiahao, Secretary of the provincial Party committee and director of the Standing Committee of the provincial people's Congress, Xu Dazhe, deputy secretary of the provincial Party committee and governor, and Li Weiwei, chairman of the provincial CPPCC attended the meeting and presented awards to the winning delegates

Hunan Provincial Science and Technology Award and Innovation Award conference was held in Changsha

it is reported that this award for the first time added an award jointly recognized and awarded by the provincial Party committee and the provincial government - Hunan Innovation Award, which covers four categories, including "science and technology innovation Award", "Product Innovation Award", "Cultural Innovation Award" and "management innovation award", with no more than 10 projects in each category. In the "Hunan provincial first innovation award evaluation criteria and list of objects to be commended" released by the Hunan provincial government station, the "high-precision and high-efficiency 56 meter concrete pump truck" developed by Zoomlion Heavy Industry Co., Ltd. ranked first in the list of "product innovation awards". In the afternoon of that day, Liuquan, supervisor of Zoomlion Heavy Industry Co., Ltd., Wu Dezhi, director of Zoomlion concrete pumping Research Institute, etc. attended the meeting and received the award. "This is the crystallization of our R & D team!" On the occasion of the award, Wu Dezhi was filled with emotion

overcome difficulties in the R & D stage, and the craftsman spirit has created a high-quality pump truck.

according to Wu Dezhi, in order to meet the needs of customers, Zoomlion launched the 4.0 product upgrading strategy in 2015. Zoomlion Concrete Machinery Co., Ltd. targeted the 56m pump truck with the largest market coverage as an upgrade pilot product, and transferred more than 10 core backbones from the market, technology, manufacturing, process, quality, service and other departments to form a research and development team to carry out technical research around pumping efficiency, fatigue life of structural parts, boom control, stability control of the whole machine and energy conservation

"the reliability of structural parts is a key factor to determine the service life of the pump truck." Wu Dezhi introduced. In the past, the development path of pump truck was to develop and manufacture products, sell them to customers, and then practice on the construction site; If there are any problems, they will be fed back to the manufacturing enterprises by the users after the actual operation. The innovation ability of China's new material industry is even more stretched. Now, in order to solve the problems and prolong the service life of products, Zoomlion Heavy Industry Project Team proposes a fatigue life simulation method of pump truck structural parts based on virtual prototype for structural parts such as boom and underframe legs, predicts the fatigue life of structural parts in the design stage, and judges the weak position of fatigue life of components. Classify and judge each weld of the structural parts, and the welds of different quality levels correspond to different fatigue stress thresholds, so as to ensure that each weld has the required fatigue life. Then, the field equivalent test is carried out

"some places can't reach the expected life, so they start from scratch, redesign and manufacture, and then experiment until they reach the goal." Li Xiangan, the project team, revealed to the media that in the winter of 2015, the test entered a critical period. It was necessary to simulate the workload of the pump truck for more than 10 years in more than 3 months, and work continuously every day. Several members of the project team took turns on duty

Kung Fu pays off. The test results of the equivalent bench test in the field show that the boom and underframe legs and other structural parts of the 56 meter boom concrete pump truck, which have been fatigue optimized, have a service life of 450000 m3 without cracking, and have reached the advanced level in Europe

in addition to the "fatigue life of structural parts", this pump truck also carries out technical breakthroughs in aspects such as pumping efficiency, fatigue life of structural parts, boom control, overall stability control and energy saving

put into the market and won praise repeatedly. The market share ranked first in the world.

now, Zoomlion's high-precision and high-efficiency 56 meter concrete pump truck has made a breakthrough in reliability, stability, maintainability, cost performance of accessories. Cracks caused by metal fatigue will bring disasters to mankind and system remote upgrading and other industry common problems: high-precision and high-efficiency High pressure pumping system, the pumping efficiency is% higher than that of the industry, and the energy consumption is% lower than that of the industry; The boom active vibration reduction technology realizes that the vibration at the end of the boom is controlled within 200mm under all working conditions to ensure construction safety. The self-adaptive pumping control technology under all working conditions focuses on breaking through the pumpability of poor materials, effectively overcoming the common problem of "pickiness" in the pumping system, and reducing the pumping pipe plugging rate by 65%. At present, the product has 62 patents, including 41 invention patents, 18 utility model patents and 3 design patents

it is understood that in the recent 4.0 product national tour held by Zoomlion Heavy Industry, this pump truck also received a lot of praise. Many customers personally got on the car and praised the "tall" appearance and configuration of the vehicle. At present, the product has been sold to Anhui, Hubei, Shanghai, Guangdong, Jiangsu and northwest provinces and regions on the assumption that the oil is improperly used, with a cumulative sales volume of 2.12 billion yuan, and its market share ranks first in the world among similar products

according to the person in charge of relevant projects of the company, in addition to the concrete pump truck products, the "key technology and application of 3200 ton crawler crane for nuclear power construction" project declared by Zoomlion won the second prize of the 2016 Hunan Provincial Science and technology progress award, "high chromium cast iron, its thin-walled pipe fittings and the preparation method of the thin-walled pipe fittings" invention patent won the first prize of the 2016 Hunan Provincial Patent Award, These three items were also commended and rewarded by the provincial government
