The course of work of puncture earthing clamp of the present invention is as follows: in puncture action in earlier stage, as shown in Figure 2, upper shell 2, enough spacing are kept between lower house 4, floating gear 9 and sleeve 19 form ratchet structure and be in engagement, ground loop 22 is articulated on the lower metal puncture tooth 27 on lower house 4, puncture earthing clamp is hanging to wait to puncture by recycling insulating bar, and insulated conductor 28 treats site of puncture, make to treat that puncture insulated conductor 28 outer surface contacts with the upper metal puncture tooth 21 on upper shell 2, described ground loop 22, treat that puncture insulated conductor 28 lays respectively at the both sides of telescopic lever 1.
Puncture command signal is sent to microcontroller by remote controller, the enabling signal that microcontroller sends starts drive motors 13, driven wheel 11 on drive motors 13 output shaft drives reduction gearing 15 to rotate, travelling gear 16 and reduction gearing 15 synchronous rotary, floating gear 9 is driven to rotate, floating gear 9 drive sleeve 19 rotates, sleeve 19 drive nut 20 rotates, make telescopic lever 1 relative to the downward rectilinear motion of sleeve 19, thus drive upper shell 2 to move downward relative to lower house 4, in the process, puncture the insulation sheath waiting to puncture insulated conductor 28 after upper metal puncture tooth 21 pressurized to contact with wire metals core body, the insulation sheath puncturing ground loop 22 after lower metal puncture tooth 27 pressurized contacts with metallic core.Puncture pressure control mechanism on puncture earthing clamp carries out puncture Stress control by the preset value of torque setting spring 17, when the pressure that punctures reaches preset value, the end ratchet that floating gear 9 and sleeve 19 form is threaded off, overcome torque setting spring 17 thrust to move downward, and depress the puncture travel switch 18 of corresponding side, make mutually to skid between floating gear 9 and sleeve 19 ratchet, namely puncture earthing clamp is in clamping puncture state, as shown in Figure 3, Figure 4.The actuating signal of puncture travel switch 18 exports microcontroller to, and control drive motors 13 by it and shut down, puncture completes.After puncture completes, pine can be sent by remote controller to microcontroller and move back command signal, reverse signal is sent to drive motors 13 by microcontroller, drive motors 13 carries out reverse rotation after starting, upper shell 2 is moved upward relative to lower house 4, until the spacing between upper shell 2 and lower house 4 return to puncture before normal level.
Consider the cross section normally circular configuration treating puncture insulated conductor 28, ground loop 22, can the puncture portion on upper shell 2 be arranged curved, be fixedly connected on the upper metal puncture tooth 21 ring puncture portion arrangement in puncture portion, similarly, also can the puncture portion on lower house 4 be arranged curved, be fixedly connected on the lower metal puncture tooth 27 ring puncture portion arrangement in puncture portion, as shown in Figure 2.Therefore, when upper shell 2 moves downwardly to clamping puncture state as shown in Figure 4 relative to lower house 4, upper shell 2, lower house 4 can coated state with wait the insulated conductor 28 that punctures, ground loop 22 contacts, add upper shell 2, puncture portion on lower house 4 with wait the insulated conductor 28 that punctures, contact area between ground loop 22, guarantee point of puncture contact stabilization, improve and wait the insulated conductor 28 that punctures, the clamping puncture stability of ground loop 22, and make metal puncture tooth 21, lower metal puncture tooth 27 punctures more easily waits the insulated conductor 28 that punctures, the insulation sheath of ground loop 22, be conducive to the complete machine energy consumption reducing puncture earthing clamp.
In the process of moving relative to lower house 4, deflection or rotation is there is in order to prevent upper shell 2, as shown in Fig. 1, Fig. 3, Fig. 5, the telescopic lever 1 of two groups of same structures, nut 20 can be set, correspondingly, the floating gear 9 of two groups of same structures, sleeve 19 are set, namely the ratchet structure of two groups of same structures is set, two telescopic levers 1 be arranged in parallel, thus effectively prevent upper shell 2, relative to lower house 4, deflection or rotation occur, job stability, the reliability of earthing clamp of guaranteeing to puncture.Two floating gears 9 also be arranged in parallel and simultaneously with travelling gear 16 engaged transmission, pinion stand 10 fixedly mounts two puncture travel switches 18, these two puncture travel switches 18 are electrically connected with microcontroller respectively, the actuating signal of its induction all exports microcontroller to, when microcontroller detect two puncture travel switches 18 all action time, namely microcontroller controls drive motors 13 and shuts down, and puncture completes.Adopt such structure to make the complete machine structure of puncture earthing clamp compacter, and clamping puncture action is more stable, reliable, effective puncture pressure of output also more greatly, is conducive to the complete machine energy consumption reducing puncture earthing clamp.After tested, the complete machine energy consumption of puncture earthing clamp can be controlled in below 0.5mW.
Described upper metal puncture tooth 21, lower metal puncture tooth 27 double as high pressure detector probe, when it punctures after insulation sheath contacts with metallic core, if wire 28 is with high pressure, to conduct on ground loop 22 by high pressure by upper metal puncture tooth 21, lower metal puncture tooth 27, the high pressure test side of high voltage testing circuit is connected with ground loop 22.As shown in Figure 8, during without high input voltage, triode Q1, Q2 all end, and high voltage testing circuit output low level is to microcontroller; When there being high input voltage, high pressure causes triode Q1 base stage and makes triode Q1 conducting after resistance R1, R2 dividing potential drop, triode Q2 also conducting then, and high voltage testing circuit exports high level to microcontroller.When microcontroller detects that high voltage testing circuit exports as high level, can judge that wire 28 is charged, the warning device of output signal driving subsequently sends light signal or acoustical signal carries out alarm for high voltage instruction.If warning device does not send light signal or acoustical signal carries out alarm for high voltage instruction, then can carry out ground wire mounting operation safely.Like this, be integrated in one by high voltage testing instruction is punctured with remote control, can also confirm the charged situation of circuit while puncture procedure, thus eliminate the electrical verification operation before ground wire mounting, improve the operating efficiency of line maintenance.
Puncture earthing clamp compact conformation of the present invention, quality is light, volume is little, and power transmission lines overhauling personnel can use insulating bar to be suspended to easily to wait to puncture and insulated conductor 28 treats site of puncture.Because puncture earthing clamp adopts the remote control transceiver module be made up of remote-control receiving circuit and remote controller, antijamming capability is strong, operating personnel can carry out straighforward operation on ground, and manipulation is convenient, simple, and this Touchless manipulation mode fundamentally ensure that the personal safety of operating personnel.Accurately can be controlled puncture pressure by puncture pressure control mechanism, puncture pressure regulating mechanism, make the moderate pressure that punctures, point of puncture contact stabilization, guarantees to cause damage to wire core body.Therefore, in Electric Power Line Overhaul, maintenance work, adopt puncture earthing clamp of the present invention effectively can improve the operating efficiency of operating personnel, alleviate the labour intensity of operating personnel.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, it should be pointed out that all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
