Description

High-altitude quick wiring device for high-voltage electric test Technical Field The invention relates to the technical field of manufacturing of special instruments for resistance measurement, in particular to high-altitude quick wiring equipment for a high-voltage electric test. Background The high-voltage electric test is a core link of inspection and acceptance before operation, overhaul in operation and fault investigation of electric power system equipment, and the operation safety, the wiring reliability and the operation flexibility of the high-voltage electric power system equipment directly influence the test efficiency and the data accuracy by taking high-altitude cable wiring operation as a key step of test implementation. At present, the high-altitude electrical test wiring tool widely applied in the power industry mainly comprises dead-weight wiring pliers, the tool has extremely high popularity in outdoor and high-altitude wiring scenes of transformer substations by virtue of the advantages of simple structure, convenience in operation and low cost, and the intrinsic structural defect of the dead-weight wiring pliers in the actual operation process causes difficulty in adapting to complex working condition requirements. Firstly, dead weight type wiring pliers completely rely on the self weight of a tool to realize the biting clamping of a cable, the clamping force is limited, the function of cleaning foreign matters is avoided, the high-altitude cable is exposed in natural environment for a long time, water frost wall hanging is easy to form in rainy and snowy weather, dust, sand grains and corrosive impurities in the air can be accumulated under the sunshine condition, and the impurities can be attached to the surface of the cable and the contact surface of a clamping head of the wiring pliers. When wiring, foreign matters are clamped between the clamping head and the cable, on one hand, the clamping head is dirty, the stability of conductive contact is damaged, test signals are attenuated, data drift is caused, even detection interference misjudgment occurs, on the other hand, the existence of the foreign matters can aggravate the abrasion of the clamping head, the service life of a tool is shortened, and the local insulation performance is possibly reduced due to water frost attached under a humid environment, so that the operation safety risk is increased. Secondly, the holding rod of current dead weight formula wire connecting pliers is mostly integral type rigid structure, only can realize perpendicular suspension centre gripping, can't adjust the holding rod angle of buckling according to the detection demand. In personnel's operation scene of ascending a height, if need detect the specific section, branch node or the hidden position of cable, restricted by holding rod rigid structure, the wiring pincers are difficult to accurately extend to the target detection point, and operating personnel need frequently adjust the position of ascending a height, and the rigid holding rod still can't realize covering detection on a large scale, leads to partial region to detect to miss, leaves equipment operation potential safety hazard. Finally, after the high-altitude operation is finished, dust, water frost residues and corrosive impurities attached to the surface of the clamp head of the wiring clamp cannot be cleaned at the first time on site, the dirt is gradually solidified and hardened in the natural air drying, insolation or temperature change process to form refractory attachments, in the prior art, operators need to carry tools back to the ground and clean the tools in a manual wiping mode, the cleaning is not timely and the efficiency is low, and during subsequent use, the refractory dirt is difficult to thoroughly clean, so that the clamping stability and the service life of the tools are further reduced. Disclosure of Invention (One) solving the technical problems Aiming at the defects of the prior art, the invention provides high-altitude rapid wiring equipment for a high-voltage electric test, which solves the problems that the existing dead weight wiring pliers cannot clean the surface dirt of a cable detection position, the chuck dirt is difficult to clean in time, and the detection range of a rigid structure is limited. (II) technical scheme In order to achieve the purpose, the high-altitude quick wiring device for the high-voltage electric test comprises a main shaft, wherein a cleaning part is arranged on the main shaft, an adjusting part is connected between the main shaft and the cleaning part, a decontamination part is arranged on the main shaft, and a clamping part is arranged on the decontamination part. Preferably, the cleaning part comprises an L-shaped locating plate, the L-shaped locating plate is fixedly connected to the outer wall of the main shaft, one end of the L-shaped locating plate is fixedly connected with a box body, two rotating shafts are rotatably connecte
