[Abstract]:Full hydraulic rock drilling trolley has been widely used in energy development, transportation, hydropower engineering and national defense construction because of its advantages of low energy consumption, less pollution, high reliability and good economic benefits. It liberates the construction personnel from heavy and arduous rock drilling operations, and also effectively improves the utilization rate of resources. The feed support system of rock drilling trolley is the key part of hydraulic drilling trolley, and its performance directly affects the overall performance of rock drilling trolley. This subject comes from the development project of full hydraulic drilling trolley in Qianshan Iron Mine of Anshan Iron and Steel Group Mining Company, which takes Atlas Copco as an example to develop the related drilling trolley. In this paper, the feed support system of hydraulic drilling trolley is taken as the research object, through field measurement, the three-dimensional model of feed support system is established, and its dynamic characteristics and finite element analysis are carried out, and the mechanical characteristic data of each key component are obtained, which provides guidance for the development of rock drilling trolley. In this paper, taking a drilling trolley of Atlas Copco Company of Sweden as an example, through field measurement, the three-dimensional data information of the trolley is obtained and the three-dimensional model of the feed support system of the drilling trolley is drawn. After assembling each component and checking the relevant interference, the three-dimensional assembly model of the feed support system of the drilling trolley is obtained. Secondly, on the basis of the assembly model, the virtual prototype model of the trolley feed support system is obtained by importing it into ADAMS. Combined with the actual working condition of the drilling trolley, the dynamic simulation analysis of the six main dangerous working conditions of the feed support system of the drilling trolley is carried out, and the dynamic correlation curves of the key components of the feed support system are obtained, which provides the necessary reference for the selection and optimization of the driving cylinder, and also provides data support for the finite element analysis of the parts and components of the feed support system. Finally, the statics and modal analysis of the feed support system of rock drilling trolley under different working conditions are carried out by using ANSYS Workbench, and the stress and deformation of the whole system and its components, as well as the resonance frequency, vibration mode and its corresponding changing trend of the system are obtained, which provides the basis for the future feed support system to avoid the frequency of resonance area.
