A kind of lead obstacle-crossing robot walking device
Technical field
The present invention relates to line walking and the protection field of high voltage transmission line, but especially in regard to a kind of obstacle crossing type single conductor and multiple fission conductor robot walking device.
Background technology
In order to ensure the normal operation of electric power circuit, need to carry out periodical maintenance to transmission line of electricity.Patrol and examine and not only understand the operation conditions of grasping circuit, also can in time find the variation of defective and the ambient environment situation of circuit and equipment, safeguard for maintenance of track and give information.It at present mainly is the mode that adopts the artificial visually examine to check, but China's transmission line of electricity mileage is long, wide coverage, some circuit is also crossed over mountain area, great river, meadow and virgin forest etc., and this just makes, and to patrol and examine labor intensity large and be difficult to guarantee that cyclic in-position measuring rate and impact patrol and examine quality.In order to remedy the deficiency of manual inspection on these circuits, just in the urgent need to using the inspection robot based on Robotics to come the indirect labor to patrol and examine.This has not only guaranteed to patrol and examine efficient, patrol and examine quality, has also reduced routing inspection cost.
, wide coverage long for China's transmission line of electricity mileage, circuit need to be through areas such as high mountain great river virgin forests greatly, actual conditions that the manual inspection difficulty is large etc., also along with the continuous progress of Robotics, adopt inspection robot based on Robotics to come the indirect labor to patrol and examine and the replacing manual inspection has become trend of the times.This improves and patrols and examines operating personnel's labor condition for improving power department automated job degree, improves and patrols and examines level of operation, and improve and patrol and examine operation quality and all have great importance, and the good operation that guarantees China's transmission line of electricity is had positive effect.
Lead obstacle-crossing robot walking device of the present invention can become inspection robot after carrying video transmission equipment, carrying deicing mechanism can become deicing robot.
Summary of the invention
Technical matters to be solved by this invention is: robot will run into various gold utensils when wire is walked, such as stockbridge damper, aluminium hydraulic pressed connecting pipe, suspension clamp etc.In order to increase work efficiency, robot will have the ability of the above-mentioned obstacle of independent technological leapfrogging.The present invention proposes a kind of rotary machine human arm of passing through with the method for avoiding obstacles, make quick, stable the clearing the jumps of robot.
Therefore, the present invention proposes a kind of lead obstacle-crossing robot walking device, it adopts both arms three joint wheeled constructions, both arms are alternately held line to avoid obstacle during obstacle detouring, comprise front walking wheel 1, rear walking wheel 2, front contact roller 3, rear contact roller 4, front walking wheel arm 5, rear walking wheel arm 6, front contact roller arm 7, rear contact roller arm 8, four front motors 9, four rear motors 10, front joint arm 11, posterior joint arm 12 and bodies 13, described body 13 is elliposoidal, and described body 13 comprises drive motor, drop-gear box, control system and the power supply of driving joint arm motion.
