[Abstract]:Tire crane is an important equipment in port operation. QLY50 fully hydraulic tire crane can adapt to the port wharf working environment very well. In the cargo yard the passage road is narrow and the parking space is very small. Even when there is no standard crane working position, it can still carry on the production loading and unloading operation, has the very high reliability, therefore this paper carries on the analysis and the research to the crane hydraulic system. It solves the problems in the process of operation, and the research results have important practical application value. The QLY50 full hydraulic tire crane used in Qinhuangdao port has been running at high load for a long time, which leads to a series of problems such as large oil leakage, high oil temperature and damage to hydraulic components. In this paper, the main technical performance and main structure of the crane are analyzed, the hydraulic system and the hydraulic components are introduced, and the hydraulic pump circuit, hoisting mechanism loop and amplitude change mechanism loop are analyzed emphatically. The circuit of walking mechanism, the loop of rotary mechanism and the circuit of supporting leg provide the basis for its overhaul and renovation. On the basis of the analysis of the rotary mechanism, the simulation calculation is carried out by using AMEsim software, which is one of the important mechanisms of the crane. Its dynamic characteristics directly affect the working performance of the whole crane. Through the simulation calculation of the hydraulic system, the pressure dynamic characteristics of the system are analyzed, and the slope curve is properly controlled. It can improve the stability of rotary operation under the condition of large moment of inertia, at the same time, it has higher working efficiency in the case of small moment of inertia, and increases the reliability of the whole machine. Safety. It can also provide theoretical basis for improving, optimizing and designing the rotary hydraulic system of tire crane. According to the principle and working condition of the hydraulic system of crane, this paper analyzes the hydraulic system and finds out the cause of the malfunction of the hydraulic system in combination with the actual operation on the spot. At the same time, the corresponding improvement scheme is put forward to solve the problems of wire rope opening damage and the oil temperature of hydraulic oil being too high.
