And drill pipe section composition, leading screw section and drill pipe section rotation direction are identical, one is coaxially connected from up to down, and connecting terminal and handle are connected to
The leading screw section upper end of grounding rod main body；Connection swivel nut is threadedly coupled to form lead screw pair with the leading screw section of grounding rod main body；
Connection swivel nut both sides are respectively fixedly connected with a supporting rod, and two supporting rods are arranged in inverted V-shaped, two supports
The lower end of bar is respectively fixed with a pedal.
Further, the leading screw segment length of the grounding rod main body is more than drilling rod segment length, and connects swivel nut and adjust to leading screw
When section lower end, the lower end of drill pipe section is not less than pedal.
Further, the outer diameter of the leading screw section of the grounding rod main body is equal to or less than drill pipe section outer diameter.
Further, the supporting rod lower end and pedal connection in T shape, two pedals are arranged in parallel.
Further, the pedal bottom is equipped with sting.
Further, the handle is telescopic structure or folding body of rod structure design.
Further, the handle with the leading screw section top of grounding rod main body is in T shape is fixedly connected.
Further, the handle passes through the bidirectional ratchet mechanism leading screw section top in T shape for being connected to grounding rod main body
End.
The utility model has the beneficial effects that：
The utility model provides a kind of novel grounding rod, and drill pipe section is arranged in grounding rod main body hypomere, using screw-in side
Grounding rod main body is wedged ground by formula, and effective solution hammer mode setting ground connection drill rod is difficult to the problem wedged and pulled out.
The present apparatus is especially suitable for cold district winter construction, and staff scrunches pedal, while both hands pull handle, and operator can be abundant
Connection swivel nut and grounding rod main body are pushed using the weight of oneself, is exerted a force downwards by lead screw pair and drill pipe section is screwed in into underground, kept away
Exempt from directly to push grounding rod energetically, muscle power has been greatly saved, the operation of cuttage grounding rod can be completed in a people；Reversely pull hand
Handle can easily extract grounding rod main body, and working efficiency greatly improved, and save manually, reduce labor intensity, ensure that good
Good earthing effect.
The technical solution of the utility model is described in detail with reference to the accompanying drawings and detailed description.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
In figure：1, connecting terminal, 2, handle, 3, grounding rod main body, 31, leading screw section, 32, drill pipe section, 4, connection swivel nut, 5,
Supporting rod, 6, pedal, 7, sting.
Embodiment 1
From fig. 1, it can be seen that technical solutions of the utility model include grounding rod main body 3, connecting terminal 1, handle 2, connection swivel nut
4, supporting rod 5, pedal 6, grounding rod main body 3 are made of the identical leading screw section 31 of rotation direction and drill pipe section 32, leading screw section 31 and drilling rod
One is coaxially connected from up to down for section 32.
Connecting terminal is fixed in 31 upper end of leading screw section of grounding rod main body, to connect ground wire.
Handle 2 with 31 upper end of leading screw section of grounding rod main body is in T shape is fixedly connected, for ease of carrying and storing, handle
It may be designed to telescopic structure or fold body of rod structural poles body, when use is unfolded to increase rotating torque.
Connection swivel nut 4 is threadedly coupled to form lead screw pair with the leading screw section 31 of grounding rod main body, and drill pipe section 32 is located at connection spiral shell
4 lower section of set；4 both sides of connection swivel nut are respectively fixedly connected with a supporting rod 5, and two supporting rods 5 are opened downwards in inverted V-shaped
It opens, the lower end of two supporting rods 5 is respectively fixed with a pedal 6；Pedal 6 and the T-shaped connection in 5 lower end of supporting rod, and two pedals are parallel sets
It sets, balance and stability can be played the role of.31 length of leading screw section of the grounding rod main body is more than 32 length of drill pipe section, and connects spiral shell
When set 4 is adjusted to leading screw 31 lower end of section（I.e. grounding rod main body 3 is adjusted to highest point）, the lower end of drill pipe section 32 is not less than pedal 6
（That is the line of two pedals）；The outer diameter of the leading screw section 31 of grounding rod main body is equal to or less than 32 outer diameter of drill pipe section.
6 bottom of pedal is equipped with sting 7, prevents drill pipe section from piercing 5 stress of supporting rod in surface process and skids.
In use, grounding rod main body 3 will be adjusted to highest point, that is, the lower end that swivel nut 4 is located at leading screw section 31 is connected, will be grounded
The lower end of stick main body drill pipe section 31 contradicts ground, and construction personnel firmly scrunches pedal, and the sting 7 of pedal lower part is made to be embedded in ground surface soil
Earth, and stand on pedal, handle is pulled using leading screw section 31 and the lead screw pair for connecting the composition of swivel nut 4, and grounding rod main body is screwed in
In soil.The design of the pedal structure can make construction personnel that the weight of oneself be made full use of to pressurize for grounding rod main body, only pull
Grounding rod main body can be screwed in underground by handle, avoided and directly pushed grounding rod energetically, muscle power, a people is greatly saved
Complete the wedging operation of grounding rod；Handle is reversely pulled after construction easily to screw out grounding rod main body.
