Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
The present invention adopts ratchet mechanism to increase moment, and then increase and twist the dynamics of nut of tearing open, make operator remote still can easy removal and mounting electrical element, be provided with bearing 5 at the two ends of ratchet shaft 13, the resistance of ratchet shaft 13 carry-over moment can be reduced, the corresponding dynamics increasing pullover 1.Concrete structure is see shown in Fig. 1, Fig. 2, the upper end of the insulation body of rod 8 is connected with ratchet mechanism, ratchet 15 is articulated with the inwall of pawl seat 14, the pullover 1 detachable upper end being connected to the ratchet shaft 13 of ratchet mechanism, the lower end of ratchet shaft 13 is provided with spacing shoulder 6, the two ends coordinated with pawl seat 14 at ratchet shaft 13 are respectively equipped with bearing 5, seal cover 3 is provided with in the upper end of pawl seat 14, the lower end of pawl seat 14 is fixed with connector 11, connector 11 is provided with blind hole 10, be provided with spring 7 in blind hole 10, the insulation body of rod 8 is fixedly connected with the lower end of connector 11.When the downward operation of the head of operation bar, the spacing shoulder 6 of ratchet shaft 13 can avoid ratchet shaft 13 to move down, and spacing shoulder 6 is in blind hole 10, and blind hole 10 is for holding spring 7, and spring 7 is connected with the lower end of ratchet shaft 13; Spring 7 plays the effect compressing the nut screw dismantled or turn, and during owing to being in long-range, dynamics on hand is not easily all delivered to stress point, adopts spring 7 to play the effect of compression, is convenient to dismantle nut.Spring 7 also plays the effect of support limit to ratchet shaft 13.
Wherein, the length of electric power overhaul insulation operation bar is 1-5m, and preferred length is 3-4m.
Buzzer siren 4 is provided with at the outer wall of pawl seat 14.Buzzer siren 4 is set in end, sends alarm signal when object is charged, operator is taken measures, avoid dangerous generation.
During due to electric power maintenance operation, operator needs the position according to maintenance thing and adjusts and select suitable job position, generally also need ascend operation simultaneously, more optimize to make operating type, operator generally selects the position simultaneously can carrying out operation to several position as far as possible, like this, some maintenace points can be in high position, some meetings are in lower position, namely far and near height all may be different, like this, in the nut screw of installing for needs, to nut screw be first put in pullover 1, also more convenient for high position, and for lower position, then cannot nut be fixed in pullover 1, then long distance is to maintenance point, therefore magnetic patch 2 is inlayed in the inside of pullover 1, utilize magnetic like this, nut is held the maintenace point then sent into and specify, laborsavingly like this to save time, easy to operate, avoid and change a lot of trouble such as position, simultaneously, nut under dismounting also can be inhaled on pullover 1, avoid the danger of arbitrarily dropping.
In order to the different maintenance point of suitable far and near height changes the loaded down with trivial details of position, hollow drawing and pulling type telescopic insulating bar selected by the insulation body of rod 8.Expansion link of the prior art can be adopted, because multistage needs the expansion link of joint connection in site mode to carry inconvenience, and, sometimes the distance estimated is also not too accurate, therefore, adopts the insulating bar of pull one, according to the distance pull expansion link of reality, use more flexible.
The expansion link that the present embodiment is enumerated is as follows: the top of the described insulation body of rod 8 is withdrawing part 18, bottom is support portion 19, the perforation 16 of some lateral direction penetratings is vertically evenly equipped with in withdrawing part 18, the upper end of support portion 19 is provided with the lateral connection hole with described perforation 16 equal diameters, withdrawing part 18 is through in support portion 19, and is fixedly linked by the bolt pair 17 running through lateral connection hole and perforation 16.Some perforation 16, any one all can be connected with the lateral connection hole of support portion 19, like this, increase the random flexibility of expansion link adjustment, also make operator more easily find the length of the insulating bar of applicable distance, operator is avoided also to need the crooked orientation waiting adjustment health, meanwhile, bolt pair 17 connects fastening, also makes the insulation body of rod 8 more integrated, make more to stablize on the whole, transmitting force preferably.
Anti-slip veins 9 is provided with at the lower end outer wall of the insulation body of rod 8.Because operating personnel is generally with gloves operation, easily skid, anti-slip veins 9 is set, when also avoiding operator to operate, hold skidding, reduce the efficiency of operation.
Further, connector 11 is fixedly connected with by the internal and external threads matched with pawl seat 14, and connector 11 is adopted with the insulation body of rod 8 and is screwed.Employing is threaded fastening, makes operation power transmission more stable, connects mounting or dismounting easily, also not fragile, long service life.
The present invention adopts ratchet mechanism to increase moment, and then increase the dynamics of twisting and tearing nut open, make operator remote still can easy removal and mounting electrical element, be provided with bearing at the two ends of ratchet shaft 13, the resistance of ratchet shaft 13 carry-over moment can be reduced, the corresponding dynamics increasing pullover 1, buzzer siren 4 is set in end simultaneously, send alarm signal when object is charged, operator is taken measures, avoid dangerous generation.
