3月11On the same day, Hunan Machinery Industry Association held a conference in Shanhe Industrial City, which was developed by Shanhe Intelligent Equipment Co., LTD“SWCHSeries full hydraulic crawler pile frame"SWDH series open-air hydraulic drilling truck" scientific and technological achievements evaluation meeting and new product identification meeting。The appraisal committee is composed of professors and experts from seven universities, research institutes and third-party testing institutions, including National University of Defense Technology, Hunan University, Changsha University of Science and Technology, Changsha Institute of Mining Research, and National Center for Quality Supervision and Inspection of Construction Machinery for Urban Construction。Appraisal committee hearingI took the technical research report of the project team, carefully reviewed the relevant materials, and watched the demonstration of the prototype on site。The experts at the meeting agreed that“SWCHThe results of the "series of full hydraulic crawler pile frame" project have made outstanding contributions to breaking through the situation of simple imitation of China's full hydraulic crawler pile frame, the core technology is subject to people, and the industry development is large but not strong;"SWDHSeries of open-air hydraulic drill carThe performance of the project results can replace imported equipment, breaking the long-term monopoly of foreign manufacturers in the open-air top hammer drill market, and highly appraised the advanced nature, innovation and market application prospects of the project results。

  The experts at the meeting pointed out:“SWCHSeries full hydraulic crawler pile frame "project in the development of full hydraulic crawler pile frame abandoned the domestic long-term imitation of foreign advanced products, broke the monopoly of foreign brands, promoted the development of industry technology, fill the domestic technology gap, its uniqueMultistage combined hydraulic cylinder vertical mast with large Angle amplitudeThe technology makes the small and medium-sized pile mast and transport transfer more efficient and convenient. The special retractable chassis and sliding shoe device can realize the safe and stable operation of large pile frame and promote the safe construction.The self-developed intelligent control system is ahead of the traditional instrument control of pile frame。

  “SWDHSeries of open-air hydraulic drill carThe project abandoned the long-term aluminum alloy beam at home and abroad in the selection of drilling frame propulsion beam, and developed a new section of double-sided guide steel structure propulsion beam with low cost,Good rigidityGood process performance, high guidance accuracy。Through the research of system integration and control technology, the drilling adaptive and anti-sticking control system is developed, which effectively improves the working efficiency and reduces the drilling tool loss。The disk-type drill pipe library and the automatic drill pipe jointing and unloading system are developed. The jointing and unloading of drill pipe is simple, the working intensity of operators is reduced, and the safety hazard is eliminated。The project has passed the inspection of the third party authority, and has been recognized by the end users, and has great market potential。

  Finally, after much discussion, the Appraisal Committee agreed that“SWCHThe whole technology of series full hydraulic crawler pile frame is achieved国际Advanced level, of which small and medium-sized models of vertical mast technology, large models of stability enhancement technology and machine control technology in the international leading level”；“SWDHSeries of open-air hydraulic drilling car技术达到International advanced levelAmong them, double-sided guide cold-drawn propulsion beam technology and drilling adaptive control technology have reached the international leading level”。

  The products identified are the international leading results obtained by Sanhe Intelligent in the field of construction machinery, and also a model of successful application of Sanhe intelligent pilot innovation!
