A kind of ground lead loading and unloading device, comprises strutting piece and lever, and described lever is rotationally connected described strutting piece, and described lever one end is provided with pry head.
Further, described pry head comprises spaced inner splint and external splint.
Further, described inner splint and external splint are provided with and dodge groove.
Further, described strutting piece comprises support bar.
Further, described strutting piece also comprises with support bar and splits the extension rod being connected, and described lever is rotationally connected described extension rod.
Further, described extension rod be axially arranged with connecting hole, connecting hole described in described support bar cross-under, described extension rod is interval with some installing holes vertically, described support bar is provided with the lockhole corresponding with installing hole, and described lockhole is connected by screw rod with installing hole.
Further, the bottom of described support bar is provided with plastic anti-skid cover.
Further, between described pry head and lever, be provided with brace rod.
Further, the other end of described lever is provided with insulated handle.
The beneficial effects of the utility model:
Ground lead loading and unloading device of the present utility model, strutting piece stands on bottom surface, and the bottom of the pry head of lever and ground lead upper splicing offsets, depress lever, pry head drives contact pin lifting, can easily turn the bolt between contact pin and steel tower, and ground lead is separated to steel tower.By the use of this instrument, significantly reduce the consumption of human and material resources, improve operating efficiency, the maintenance cost of highly saving equipment damage and scrapping.
These features of the present utility model and advantage will be below embodiment, accompanying drawing in detailed exposure.
[brief description of the drawings]
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the vertical view of pry head in the utility model;
Fig. 3 is the right view of pry head in the utility model.
[embodiment]
The utility model provides a kind of ground lead loading and unloading device, comprises strutting piece and lever, and lever is rotationally connected strutting piece, and lever one end is provided with pry head.By the use of this instrument, significantly reduce the consumption of human and material resources, improve work efficiency, the maintenance cost of highly saving equipment damage and scrapping.Taking certain circuit in electrical network as example, statistics after grounding resistance measurement work in 2011 completes shows, spanner is scrapped 5,54, bolt, tower material and bolt hole damage 32 places, study for a second time courses one has flunked 2 times, path loss is disregarded for the time being, amount to 1626 yuan of economic losses, by application of the present utility model, above loss can significantly reduce.50 of work area annual grounding resistance measurement task transmission lines, if things go on like this, the application of this instrument is considerable to the saving amount of human and material resources, financial resources, and guarantees the safety of the person, electrical network, equipment in grounding resistance measurement work.
Accompanying drawing below in conjunction with the utility model embodiment is explained and illustrated the technical scheme of the utility model embodiment, but following embodiment is only preferred embodiment of the present utility model, not all.Based on the embodiment in execution mode, those skilled in the art are other embodiment that obtains under the prerequisite of not making creative work, all belongs to protection range of the present utility model.
With reference to figure 1, shown in a kind of ground lead loading and unloading device, comprise strutting piece 2 and lever 1, lever 1 is rotatably connected on the upper end of strutting piece 2, strutting piece 2 uprightly on the ground, lever 1 is provided with manipulatable end 12 and pry head 11, manipulatable end 12 and pry head 11 lay respectively at the both sides of switching place, pry head 11 correspondences are pressed on the lower end of contact pin, press down after manipulatable end 12, pry head 11 is top compressing piece upwards, even if earthing sinks to causing ground lead to pull contact pin to decline, also can lifting contact pin by this device, conveniently the contact pin of ground lead upper end is removed from steel tower, and this equipment operating is simple, lever passes through lever principle, reduce labor intensity, improve operating efficiency.
With reference to figure 3, pry head 11 of the present utility model comprises the inner splint 3 and the external splint 4 that arrange along the axially spaced-apart of lever, and inner splint 3 and external splint 4 are clamped in the bottom of contact pin between the two, facilitate location and the operation of instrument.
