Mechanism Design And Analysis Of The Disconnector Connection Board Removal Robot

The disconnector connection plate is an indispensable fitting in the power transmission link.It is widely used in high-voltage overhead power lines and substations.It plays a role in shunting power line current to various towns.Because the connecting plate is exposed outdoors all the year round,it is easily affected by weather and environment.For example,the action of wind will cause the power line to vibrate,which will cause the bolts on the connecting plate to loosen and generate sparks,which will lead to power line disconnection accidents.Once the connection with the connection board occurs,the adhesion is easy to overheat and cause an accident.When the connection board is abnormal,at present,the connection board can only be dismantled manually.When working manually in an environment of high voltage,strong magnetic field and strong electric field,a heavy electromagnetic shielding suit must be worn.Not only is the work intensity high and the operation efficiency low,but it is also very easy to cause safety accidents.Up to now,there is no robot to assist the manual disassembly of the disconnecting switch connecting plate.In order to eliminate the hidden safety hazards of manual operation and improve the efficiency of live maintenance,a new robot for disconnecting connection board removal is introduced.The main contents are as follows:(1)The overall scheme of the disconnector connection board removal robot is given,and the disassembly mechanism,frame and positioning mechanism are designed.Through the analysis of the operating environment,operating objects and tasks,the overall plan of the robot is given;based on the analysis of the disconnection principle of the disconnector connection plate,the design of the robot disassembly mechanism is completed;Coordinate the way to design the frame;according to the analysis of the positioning principle of the disassembly mechanism,design the positioning mechanism that can accurately locate the bolt.(2)Carry out mechanical analysis and optimization improvement on the key parts of the disconnector connection board removal robot.Through research on key issues such as equivalent modeling of complex structures and meshing of finite element models,the finite element equivalent models of frames and positioning mechanisms are established.Use Ansys Workbench software to conduct static analysis on the frame and positioning mechanism to optimize and improve the structural weaknesses;because the frame is the most concentrated mechanism of the entire robot load,once the problem occurs,the robot will be destroyed and cause failure,so the frame is in a breeze state random vibration analysis to optimize the structure of its weak points.(3)Developed a prototype of the disconnector connection board removal robot,and conducted experimental verification and analysis of the experimental results in the laboratory and field environment.Draw two-dimensional engineering drawings according to the threedimensional geometric model,and make prototype of the robot;complete the laboratory and field environment operation experiments and record the experimental results;by analyzing the experimental results,it is confirmed that the robot can complete the specified operation tasks and has good work performance,verified the feasibility and reliability of the design scheme.
