Mechanical System Design of Fitting Pins Maintenance for Transmission Line in Narrow Space
High-voltage transmission lines are an important channel for power transmission.There are main line fittings such as suspension clamps,shock-proof hammers,and drainage plates on the high-voltage transmission lines.These fittings are mainly connected with bolts and fittings pins.It can be said that the reliability of the fittings pin connection is directly related to the reli-ability of the fittings and pins.To the normal and stable operation of the transmission line,the harsh natural environment will in-evitably cause the corrosion,loosening or even missing of the fittings of the transmission line,which will seriously threaten the safe and stable operation of the transmission line.Therefore,the common fittings and pins of the transmission line should be sup-plemented and inserted.Maintenance work is particularly important.In response to the above problems,this article proposes a way to use a large-load UAV to carry a robot on the line and carry a hardware pin plug end tool through the robot manipulator to complete the interpolation task of the typical hardware pin of the line.Through the kinematics of the robot manipulator system Modeling analysis and control system design verified the feasibility and effectiveness of the fitting pin plugging in the narrow space.Compared with manual operation,the system greatly improves operation efficiency and reliability.The research of this arti-cle has important theoretical significance and practical application value for the intelligent operation and maintenance manage-ment of transmission lines.
