Abstract

The invention discloses a piece of high-voltage transmission line maintenance equipment which comprises a walking mechanism and a spraying mechanism arranged on the walking mechanism. The walking mechanism comprises a left walking bracket and a right walking bracket. A beam is arranged at the upper part of the left walking bracket. A first dovetail groove is arranged in the right bottom of the beam. A first dovetail tenon matching the first dovetail groove is arranged on the top of the right walking bracket. The spraying mechanism for insulation paint spraying is arranged at the bottom of a lower bracket of the left walking mechanism. The spraying mechanism comprises a spraying bracket arranged at the bottom of the lower bracket of the left walking mechanism, an insulation paint can arranged on the spraying bracket, an airless spraying machine arranged on the spraying bracket, and a CPU module. A transmission line can be sprayed with insulation paint in an all-around and even manner. Moreover, the equipment is firmly clamped onto the transmission line in the spraying process. Thus, retreat and fall are avoided in climbing, and the working reliability is improved.

Description

technical field [0001] The invention relates to the technical field of high-voltage transmission line maintenance, in particular to a high-voltage transmission line maintenance equipment. Background technique [0002] The high-voltage transmission lines laid in the early stage 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] The invention patent with the patent publication number of CN 102637488 B discloses an overhead bare wire insulation spraying device, which includes an overhead bare wire (1) and a walking hanger (6), and the walking hanger (6) is r...
