Problems solved by technology

In winter, the deepest permafrost layer in the northern region reaches 1.2 meters, which brings great inconvenience to the penetration and removal of grounding drills.
Sometimes the penetration depth does not meet the requirements, resulting in excessive grounding resistance, which poses a great threat to the personal safety of operators
The long-term manual driving and removal of the grounding drill is time-consuming, laborious and unsafe, which also reduces the service life of the grounding drill and causes a certain degree of economic loss. Therefore, the grounding drill needs to be modified

Embodiment 1

[0026] The length of the spiral part of the main body of the drill used in the present invention is 600mm, and the diameter of the drill is 16mm; the length of the drill clamp ground wire plate is 70mm, the width is 30mm, and the thickness is 3mm. The diameter of the fixed ground wire hole is 14mm. The keyway of the fixed brazing device is 55mm in length, 8mm in width, 28mm in length, and 7mm in width; the shape of the drill bit is diamond-shaped and made of alloy steel.

[0027] When in use, the main body 1 of the drill is installed on the impact drill, and the fixed drill device 3 is fixed inside the impact drill. The clamping ground wire device 2 is used to fix the ground wire, which is more convenient to use. The drill bit 4 is set in a rhombus shape, so that the impact drill It can save effort when working.

[0028] It is more suitable for the actual needs of construction sites in winter. It can be easily penetrated even in the deepest permafrost layer of 1.2 meters. It ...

Abstract

An outdoor ground drill rod used on a percussion drill comprises a drill rod body, a clamping ground line board, a drill rod fixing device and a drill bit, and is characterized in that the surface of the drill rod body is in a spiral type; the clamping ground line board is arranged on the drill rod body; the drill rod fixing device is arranged at the top of the drill rod body. Compared with the prior art, the outdoor ground drill rod used on the percussion drill has the advantages that the service life of the ground drill rod is prolonged, the ground drill rod is convenient to hit and dismount, the structure is simple, operation is flexible, use is convenient, labor intensity of working staff is relieved, a large amount of time is saved, and the labor efficiency is improved greatly. The outdoor ground drill rod is more suitable for actual requirements of the construction site in winter, and can be hit into the soil of which the deepest frozen earth layer is 1.2 m, the buried depth requirement and ground resistance requirement of the ground drill rod are met, and personal safety of the working staff is ensured.

Description

technical field [0001] The invention relates to the field of electric tools, in particular to an outdoor grounding drill for impact drills. Background technique [0002] In order to ensure personal safety, the installation of closed grounding wires in power grid construction operations is one of the important safety measures taken on the job site, and the implementation of this measure plays a vital role in the personal safety of operators. The grounding wire is connected to the earth through a temporary grounding body, and the cross-sectional area of ​​the grounding body should not be less than 190mm 2 , the depth into the ground should not be less than 0.6 meters. And the deepest permafrost layer reaches 1.2 meters in the northern region in winter, which brings great inconvenience to the penetration and removal of grounding drills. Sometimes because the penetration depth does not meet the requirements, the grounding resistance is too large, which poses a great threat to ...
