智能高壓輸電線路巡檢機器人設(shè)計
[Abstract]:High voltage transmission line inspection robot is one of the hot topics in the field of robotics. The failure of high voltage transmission line will directly lead to the great loss of people, industrial enterprises and national interests. Therefore, it is necessary to carry out regular maintenance. Due to the high intensity of transmission line inspection, complex environment and extremely inconvenient manual inspection, the robot studied in this paper is developed to replace the manual inspection of transmission lines, which can reduce the cost and ensure the safety of workers. Based on the analysis of the working environment of 500kv EHV transmission line inspection operation, this paper mainly includes the assumption of the structure scheme of the inspection robot, and the modeling, analysis and optimization of kinematics and dynamics based on Pro-E and Adams. Finally, through the developed prototype system, through the laboratory stage performance test, the actual line field inspection test, completed the initial goal, realized the robot automatic inspection. The specific research contents are as follows: firstly, the environment and inspection content of inspection operation are introduced, the typical line model is established, and according to the characteristics of different fittings, the scheme idea and type selection analysis are put forward. Secondly, the specific structure design of the inspection robot is carried out, including the design of walking mechanism, opening and closing fixture, brake mechanism, obstacle avoidance mechanism, and some auxiliary mechanisms such as counterweight. Thirdly, the theoretical model of the robot is established, which is mainly described from the degree of freedom of the mechanism, the motion form, the obstacle trajectory and the climbing. Then the 3D solid model of the robot designed in Pro-E is imported into ADAMS, to carry on the complete kinematic analysis of the robot, and the action planning of crossing the obstacle is verified and modified. Finally, the analyzed model is drawn and processed and made into a physical prototype. Through the laboratory test, based on the built line test, the experimental data are analyzed, and the possibility and shortcomings of the inspection robot are obtained. The research contents of this paper mainly verify the rationality of the designed inspection robot which can avoid obstacles independently from the aspects of theoretical model analysis, virtual prototype analysis, physical prototype analysis and so on.
