Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing, the content of embodiment is not the restriction to protection content of the present utility model.
The utility model relates to a kind of automatic detaching apparatus of power circuit earth rod, its insertion at earth rod and rise and pull out in process and do not need staff to apply external force, can reduce labour intensity significantly, increase work efficiency.
Fig. 1 shows the schematic diagram of the automatic detaching apparatus of power circuit earth rod of the present utility model.As shown in Figure 1, the automatic detaching apparatus of power circuit earth rod of the present utility model comprises the body of rod 1, rotating speed-regulating AC machine 2 and auxiliary body 6.In the utility model, preferably, the area of section of the described body of rod 1 is greater than 200 square centimeters.Can guarantee that the described body of rod 1 has enough hardness and electric conductivity like this, thus both be convenient to be inserted in ground and prevent it from damaging, electricity can be let out rapidly again.The bottom of the described body of rod 1 is provided with screw thread 5, thus makes it be more convenient for piercing in ground.In the utility model, preferably, thread depth more preferably greater than 60 centimetres, thus guarantees that the described body of rod 1 has better brill ground ability.In the utility model, more preferably, the bottom of the described body of rod 1 can arrange wolfram steel head, thus improves its hardness, can bore harder ground on the one hand, and the body of rod 1 can be prevented on the other hand damaged in brill ground process.
In the utility model, the output shaft 3 of described rotating speed-regulating AC machine 2 is connected with the upper end of the described body of rod 1 by mandrel connector 4.Like this, by adjusting turning to of described rotating speed-regulating AC machine 2, with just can realizing the brill of the described body of rod 1 and extract, thus it is bored do not need manually to carry out with extracting, therefore, it is possible to reduce the labour intensity of staff, and improve its operating efficiency.Meanwhile, the difference of base area surface hardness, can regulate the rotating speed of described rotating speed-regulating AC machine 2, thus is convenient to the better ground auger ground of the described body of rod 1.
