[Abstract]:With the rapid development of mining industry, as one of the important equipment of open-pit mine transportation, mining vehicles are increasingly developed to the large-scale development of 108-ton and 154-ton electric wheel mining vehicles are more and more widely used. Because of the large size and heavy weight of the tire, it is difficult to disassemble and assemble the tire. At the same time, the earlier manual method is not only low efficiency, labor intensity, but also easy to cause accidents. Therefore, in the mine operation, must be equipped with special equipment, in order to successfully complete the demolition and assembly of large mining vehicle tires, this kind of special equipment tire disassembly machine has been widely used. The automobile tire disassembly machine used in opencast mine is mainly composed of working device tire manipulator and construction machinery forklift truck or loader. Its function is mainly used in metal mines, non-metal mines and large truck tyres in hydropower projects, the function of which is mainly used in the disassembly and assembly of heavy truck tyres in metal mines, non-metallic mines and hydropower projects. Handling and palletizing work. This paper mainly takes the LCZ-40 heavy duty mine tire disassembly machine of a certain company as the research object. The tire manipulator of this model mainly depends on the hydraulic drive, using the combined action of the manipulator and the forklift truck, it can realize the tire clamping. Translation of left and right, lateral flip, tire flip, while the whole device can be lifted, forward and back tilt and other actions. Firstly, using the special 3D design software SOLIDWORKS, according to the drawing requirements, the modeling of the parts and components of the tire manipulator of the working device is completed. In the process, according to the performance requirements, the simple design and modeling of the hydraulic cylinder and tire are carried out, and then the manipulator parts and the simplified model hydraulic cylinder are assembled into the whole machine model. Secondly, using SOLIDWORKS data interface, the whole machine model is imported into ADAMS to complete the establishment of manipulator rigid system. Finally, using finite element analysis software ANSYS, the modal neutral files of the parts are generated from the three-dimensional parts of the tire manipulator which need flexibility. Then, in the rigid system of the manipulator, the tire is generated by using the generated modal neutral file. The rigid part of hydraulic rod is replaced with flexible body, and the rigid and flexible coupling system of tire manipulator is established. After the rigid-flexible coupling modeling is completed, the tire turnover of the manipulator and the lateral swing of the whole working device are simulated in the software ADAMS. By comparing the simulation results of rigid system and rigid-flexible coupling system, it is proved that the rigid-flexible coupling system is more realistic and the data is more accurate. Finally, due to the importance of the chuck parts, the static strength analysis and modal analysis of the chuck are completed in ANSYS to verify that the strength of the chuck can meet the requirements of the work well.
