| In recent years, accidents and disasters have happened on a global scale. The existingengineering machinery play an important role in forcible entry and rescue, but these engineeringmachinery have poor adaptability and may cause secondary collapse. Ultra-high pressure waterjet emergency rescue robot is a robot that using ultra-high pressure water jet technology forconcrete demolition. The ultra-high pressure water jet technology has characteristics of highenergy, cold, point cut off and so on. So this technology can achieve the purpose of energyconservation and environmental protection. This paper is supported by Tianjin Science andTechnology Foundation ‘Based on ultra-high pressure water jet disaster emergency rescuerobot’s research and development’(14ZCZDSF00022). In the project funding, the robot’smechanism is researched, including optimized design, dynamic analysis and experimentalresearch. The main research content is as follows:At first, this paper expounds the purpose and significance put forward by the subject,analyzes the ultra-high pressure water jet emergency rescue robot development trends at homeand abroad, and determines the ultra-high pressure water jet emergency rescue robot’s mainresearch content.Secondly, the ultra-high pressure water jet emergency rescue robot’s hardware platform isbuilt, the robot system model is established, and the demolition broken mechanism of ultra-highpressure water jet is analyzed. And according to this mechanism designs crawler walking deviceand the ultra-high pressure spray gun clamping device.Thirdly, determining the crawler walking device is rigid connection track. It belongs to thestatically indeterminate device. So the moment distribution method is adopted for solvingstatically indeterminate structure, and determines the dangerous points. Then, the structure isanalyzed by using ANASY Workbench. And the structure is verified reliably.Finally, According to reaction of spray gun problem, and using ADAMS to study the ultra-high pressure spray gun clamping mechanism’s dynamics simulation experiment. Then, thespray gun clamping device motion and torque diagram are attained. The results are analyzed. Atthe same time, the spray gun clamping device is verified through the experiment. |
