[Abstract]:Crawler crane is one of the most common mobile cranes in modern engineering construction, and torque limiter is the most important device in crawler crane safety monitoring system. With the requirements of safety and reliability of crawler cranes becoming higher and higher, the precision of the matching torque limiter is becoming more and more high. Based on the project of torque limiter of crawler crane developed jointly by Dalian University of Technology and Shanghai Piffin automatic Control Technology Co., Ltd., this paper puts forward some common core algorithms of torque limiter for crawler crane. Finally, the torque limiter algorithms of small crawler crane and medium and large crawler crane are modified in theory. The main work and research results are as follows: (1) in view of the crawler crane boom system, the theory of Temmoxinko beam and the equivalent moment of inertia method of lattice members are introduced. The jib model of crawler crane is simplified, and the stress condition of crawler crane jib is analyzed concretely. (2) for the small crawler crane, the equivalent moment of inertia of track-crane is obtained by the theory of Timuxinko beam and the equivalent moment of inertia of lattice structure. In order to improve the accuracy of the algorithm, the angle of arm root is corrected, and the field verification test of 80 ton crawler crane is carried out. The feasibility of the algorithm and algorithm correction theory is demonstrated. (3) for medium and large crawler cranes, the method of equivalent moment of inertia of lattice components and the angle of the root of boom and the angle of head of boom are modified by the theory of Temocco beam and the equivalent moment of inertia method of lattice components. Then, the revised jib angle calculation value is obtained, and the accuracy of the algorithm is improved finally, and the field verification test of 750 ton crawler crane is carried out. The feasibility of the algorithm and algorithm correction theory is demonstrated. (4) the influence of boom amplitude and arm length on the precision of moment limiter algorithm of crawler crane is further analyzed and verified by two field verification tests. In this paper, the core algorithm and algorithm correction theory of torque limiter for crawler crane are studied. The research results have been applied to the actual product development. It provides a theoretical basis for the design and improvement of torque limiter algorithm for crawler crane.
