Posted on

[ Instrument Network Instrument Development ] On September 10, 2019, the Guangdong Provincial Measurement and Control Technology and Equipment Application Promotion Association and the Guangzhou Instrument and Control Society organized and held the former AQSIQ completed by Guangzhou Special Electromechanical Equipment Testing and Research Institute in Guangzhou. Science and Technology Plan Project "Research and Application of Micro-crack Detection Technology for Crane Box Beam Based on Ultrasonic-Infrared" (No.: 2017QK064), former Guangdong Provincial Bureau of Quality and Technical Supervision Project "Analysis of Degradation of Metal Structure Performance of Portal Crane Based on Multi-feature Parameters (No.: 2016CT05) 2 Scientific and Technological Achievements Appraisal Meeting.
From South China University of Technology, Guangdong University of Technology, Guangzhou Special Pressure Equipment Inspection and Research Institute, Guangdong Optical Society, Guangdong Special Equipment Inspection and Research Institute, Guangzhou Metrology and Testing Technology Research Institute, Guangdong Quality Supervision Machinery Inspection Station, etc. 7 An expert constitutes an appraisal committee. The appraisal meeting was hosted by Zhang Jianmin, Senior Manager of Guangdong Measurement and Control Technology and Equipment Application Promotion Association and Guangzhou Instrumentation Society.
Based on the research and application of ultrasonic-infrared crane box beam micro-crack detection technology, the project designed a micro-crack detection system for crane box beam based on ultrasonic-infrared. Based on the characteristics of ultrasonic guided wave and infrared thermal imaging detection, a comprehensive method for detecting cracks in crane box beam is proposed, and a set of ultrasonic-infrared detection equipment experimental platform for crane box beam microcrack is developed. The project applies for 3 national invention patents (2 authorized), 2 software copyright registrations, 3 academic papers, and independent intellectual property rights. The experimental platform is subject to third-party professional testing and field testing, and meets the relevant standards. After demonstration use, it reflects well and has obvious social benefits prospects. The appraisal committee unanimously believes that the project is innovative and has reached the international advanced level in the research on the micro-crack size identification method of the crane box-type load-bearing beam based on the thermal image sequence wavelet neural network, and agreed to pass the scientific and technological achievements appraisal.
"Analysis of Degradation of Metal Structure Performance of Portal Cranes Based on Multi-feature Parameters" The project establishes a degradation model suitable for the performance analysis of metal structures of portal cranes, simulates the performance degradation behavior of metal structures, and studies the initial and degraded quantities of mechanical properties. In the corresponding relationship, the method of multi-feature parameter analysis of metal structure performance degradation is proposed, which provides a new simple engineering evaluation method for the safety of metal structure of portal crane. The project obtained 2 authorized utility model patents, promulgated 1 local standard in Guangdong Province, and published 3 academic papers with independent intellectual property rights. The results of the project have been applied in Guangzhou Port Co., Ltd. Nansha Grain General Terminal Branch, Guangzhou Nansha Port Container Terminal Co., Ltd. and Guangzhou Wenchong Shipyard Co., Ltd., etc., reflecting good results and having important application prospects. The appraisal committee unanimously believes that the project is innovative and has reached the domestic advanced level in the application of multi-feature parameter evaluation methods for the degradation of metal structure performance of portal cranes.
The project appraisal meeting will give full play to the third-party technology evaluation role of the science and technology community, enhance the innovation and service capabilities of the society, and promote the transfer of government functions.

Electric Hoist, can be used indepently, or together with cranes, it has Wire Rope Electric Hoist and Electric Chain Hoist two types. It can travel rotation through the trolley hanging on the I-steel, and install on the Single Beam Crane, Gantry Crane , Jib Crane , overhang crane and monorail crane to rise and fall the cargos. So it can be used in factories, mines, wharf, warehouse, freight yards, and shops and so on which need lifting equipment for lifting heavy objects. Such as mining companies and railways, docks, warehouses. It is prohibited to manned.
