Automatic spraying robot for overhead transmission line

Abstract

The invention discloses an automatic spraying robot for an overhead transmission line. The automatic spraying robot for the overhead transmission line comprises a control system and a mobile machine body; a power supply, a travelling system and a spraying system are arranged on the mobile machine body; the spraying system comprises an air pressure tank, an insulating paint barrel and a spraying head; the spraying head is designed as a mechanical arm; the paw of the mechanical arm is provided with a closed accommodating cavity; an insulating paint in the insulating paint barrel is conveyed into the closed accommodating cavity through pressure; a spraying nozzle of the spraying head is arranged on the paw of the mechanical arm and is arranged in a manner of surrounding the overhead transmission line in the radial direction. When the automatic spraying robot for the overhead transmission line works, the paw of the mechanical arm is circularly arranged at the periphery of the overhead transmission line under the control of the control system, troubles caused by manual sleeving and mounting are avoided, the situation of locking is avoided, and the automation degree and the work reliability are high. Moreover, in case that the spraying head fails and cannot spray, the power supply of the overhead transmission line is not required to be cut off, and the mechanical arm is only required to be controlled to leave the overhead transmission line and then the spraying head is maintained; the automatic spraying robot for the overhead transmission line is convenient to use and does not influence power production.

Description

technical field [0001] The invention relates to the field of insulation treatment of overhead transmission lines, in particular to an automatic spraying robot for overhead transmission lines. Background technique [0002] The overhead transmission lines laid in the early days generally adopt the form of bare wires to save construction costs, and there are great potential safety hazards. At present, the circuit system is generally constructed by artificially spraying insulating paint to improve the insulation and safety performance of exposed overhead transmission lines. Manual spraying of insulating paint has the disadvantages of low construction efficiency, low construction safety, slow speed and poor consistency of insulation effect. [0003] In order to solve the problems of low construction efficiency, low construction safety and slow speed in manual spraying of insulating paint, Chinese patent 201220165449X discloses an overhead bare wire insulation spraying device, wh...

Problems solved by technology

The pressing device (19) of this structure, if the top is too tight, not only the driving wheel (3) will not be able to move but also damage the power line (1), if the top is too loose, the pressing effect will not be achieved at all.

Moreover, only the driving wheel (3) located at the rear of the mobile vehicle body is pressed, and the driven roller (4) located at the front of the mobile vehicle body will lean back when the spraying robot climbs a slope, or even break away from the power line (1), Work reliability is poor
