Yun Xiang Heavy Duty Aerial Work Platform

As the boom-type aerial work platform is constructed in a high-rise building, the work platform is generally operated along the wall in a vertical plane. In order to achieve this movement trajectory, the operator usually needs to adjust the joint rotation angle and the arm length of the lever to achieve this purpose. The joint rotation angle is regulated by a variable amplitude cylinder. The amplitude change cylinder arm is regulated by its internal telescopic cylinder, and the crank boom type aerial work platform system that realizes the heavy work is very prominent in this aspect of intelligentization.

(1) Diagnostic device systematization. In order to achieve the purpose of automation, combining these very scattered fault diagnosis systems with computer technology into a device system, can better achieve the signal acquisition, feature extraction and status recognition, to achieve automation, and can be machine failure Diagnostic reports are automatically output in the form of displays, print drawings, and so on.

(2) Intelligent Expert System. The fault diagnosis expert system is a computer system with artificial intelligence. It not only has all the functions of system diagnosis, but also combines the expertise and thought methods of many experts with the enormous storage, calculation, and analysis capabilities of the computer to form a shared knowledge. Library. The intelligent expert system composed of artificial neural network, genetic algorithm and expert system is a high-level form of fault diagnosis technology.

(3) Electro-hydraulic integrated fault diagnosis system. The boom-type aerial work platform is an extremely complex large-scale equipment that integrates mechanical, hydraulic, computer, and electronics technologies. The more serious the consequences of the failure of equipment and the greater the impact, so it is required to ensure the reliability of these large-scale complex equipment. The development of electromechanical-hydraulic integrated fault diagnosis technology for transport boom-type aerial work platforms is very popular among customers.

(4) Multi-source information fusion technology. Traditional monitoring methods, diagnosis, and control methods mostly use a single information resource to diagnose and control a specific fault of a machine, lacking the coordinated use and comprehensive processing of multiple sources and multiple information. The multi-source information fusion technology that is destined for rapid development is a theory for the comprehensive processing and utilization of multi-source uncertainty information. This kind of technology has been successfully applied to the boom-type aerial work platform field. Its theory and method have become a new breakthrough in intelligent information processing.

(5) Remote fault diagnosis technology. This is also a trend in the development of fault diagnosis technology, combined with computer network technology. First of all, it is necessary to acquire the status signal on the mechanical equipment, and secondly, these collected signals are transmitted to the diagnosis center through the computer network technology, and then diagnosed. Remote fault diagnosis and maintenance can make mechanical fault diagnosis more flexible and convenient, and also can achieve resource sharing. (This article comes from Yuni Heavy Industries)
