Description
Technical field
The utility model relates to fast and safely exit techniques field of high-tension cable, specifically fast and safely extractor of a kind of high-tension cable, be specially adapted to change in cable line construction cutting, after utilization, need the high-tension cable that exits, prevent the injury that erroneous judgement live electric cable brings to staff.
Background technology
Power cable is different from trolly wire route, its conductor outer wrapping certain thickness insulation, there is the advantage that prevents physical electrical shock fire protection, cannot carry out direct electrical verification in the position beyond cable termination but also therefore cause, correctly judge whether cable is charged to staff and brought certain difficulty.For the injury that prevents that erroneous judgement live electric cable from bringing to staff, in " State Grid Corporation of China's electric power safety working regulation ", make following regulation: " before sawing cable; should check and conform to cable louding figure drawing; and after using instrumentation (as actinobolia) definitely to confirm that cable is without electricity; hammer into after cable core with the crooked chisel of the tape insulation handle of ground connection, can work.Hold up the people of insulation handle should wear insulating gloves and stand on insulation cushion, and take the anti-measure of burning (as mask etc.) ".
As by safety requirement, must affect construction effect, reason is as follows: 1, traditional crooked chisel design is unreasonable, can not adapt to high voltage construction, and operating personnel are with inadequate by the safe distance of thorn cable.2, traditional crooked chisel personnel that easily cause injure and adjacent operation cable is subject to damage in various degree, once there is earth fault, operating personnel are difficult to quick region out of danger.3, traditional crooked chisel is because material falls behind, of poor quality, does not often use, and corrosion is serious, and insulating bar insulation reduces, and mechanical strength reduces, and easily causes error and tool damage, poor reliability in construction.4, inner cable density in tunnel is large, narrow space, and traditional operation is easily accidentally injured other cable and maybe cannot be operated.
Traditional earthing wire-selecting method: worked is all manually with sledgehammer, the crooked chisel of tape insulation handle to be hammered into cable in the past, makes crooked chisel point and cable conductor short circuit, by cable artificial ground.As without after anomaly, change construction just can cut.According to interrelated data incomplete statistics, cutting the quantity that changes cable line increases year by year, annual 10KV and above cable are cut and are changed engineering and have up to a hundred times, successively there is erroneous judgement cable several times, cause the energy of operation cable grounding abrupt release, cause injury in various degree (because distance is too near to operating personnel, personnel are too late to dodge) simultaneously because its adjacent operation cable distance is near, also caused damage in various degree, its consequence is quite serious, for 110KV and above cable, because voltage is high, ampacity is large, by traditional construction method, once there is operation cable grounding, high-voltage breakdown electric discharge and step voltage will cause casualties.
Summary of the invention
Prick in order to overcome in order to overcome current power cable examination complicated operation, equipment heaviness, fail safe and the low deficiency of reliability that device exists, the utility model provides fast and safely extractor of a kind of high-tension cable, bundle cable is penetrated in simple to operate and realization control far away, guarantees fully personnel's safety.
The utility model is realized with following technical scheme: fast and safely extractor of a kind of high-tension cable, comprise fastener, be arranged on the ail gun on securing member, and be connected the control unit for controlling nailing transmitting with the drive unit of ail gun, on the rifle body of ail gun, be provided with junction button; Described fastener comprises rifle body fixture and is arranged on the U-shaped securing member for attached cable on rifle body fixture; Described rifle body fixture has a plate and is fixed on the pipe matching with ail gun on connecting plate, and pipe communicates with connecting plate, and pipe is provided with the draw-in groove matching with junction button, and the front end of ail gun is arranged in pipe; Described U-shaped securing member is arranged on connecting plate; Described control unit comprises that one is arranged on the casing on rifle body, control circuit for receiving remote signal, control rifle body emission bullet is installed in casing, the antenna of the shift knob, charging socket and the reception control signal that are connected with control circuit is installed on casing, also comprises a Digiplex to control circuit transmitted signal.
The beneficial effects of the utility model are: time saving and energy saving when operation, increase work efficiency, reduce labor intensity, control far away penetrate prick cable make cable conductor stable, the device of ground connection reliably and safely, thereby stop potential safety hazard, guaranteed workmen's life security.
