Grounding rock drill suitable for disassembling grounding wire in winter

Abstract

The invention relates to a grounding rock drill suitable for disassembling a grounding wire in winter; the grounding rock drill comprises a drill rod, a drill bit and a supporting rod; the drill rod and the drill bit are of an integrated structure; the drill bit is of a conical structure; the supporting rod is welded to the top of the drill rod; the supporting rod is in an isosceles triangle; thetop end of the drill rod extends out of the bottom edge of the isosceles triangle, and a mounting hole is formed in the waist of the supporting rod; the bottom end of the drill rod extends to form thedrill bit, and a marking line is arranged on the drill rod; the drill rod is of a regular prism structure, or the drill rod is of a circular truncated cone-shaped structure with a large upper part and a small lower part. The grounding rock drill has the advantages of being reasonable in structure and easy to machine and manufacture. According to the isosceles triangle supporting rod, the safety of a human hand is protected, the force surface of a large hammer is increased; the top end of the drill rod extends out of the supporting rod, so that the beating resistance of the grounding rock drill can be improved. The drill rod adopts a regular prism or a circular truncated cone structure, so that the grounding rock drill can be conveniently pulled out of frozen soil. A marking line is arranged on the drill rod, so that safety monitoring is facilitated, and the burial depth is effectively recognized.

Description

technical field [0001] The invention relates to a grounding drill suitable for installing and disassembling grounding wires in winter. Background technique [0002] Frozen soil layers will be formed in winter in Northeast China, and the soil will become extremely hard. During the installation and removal of grounding wires in power distribution operations (including some power transmission operations), the existing grounding solders are difficult to install and even more difficult to pull out, and often break or even The phenomenon of scrapped ground solder. [0003] Chinese Patent Application No. 201420462776.0 discloses a grounding drill structure that is not easy to loosen and can be easily pulled out, which increases the strength of the grounding drill to a certain extent, and a hand-held structure is set on the top, which is more convenient to pull out. However, in winter in the Northeast, due to the The rod is a cylindrical structure, and even if there is a hand-held ...

Problems solved by technology

[0002] Frozen soil layers are formed in winter in Northeast China, and the soil becomes extremely hard. During the installation and disassembly of grounding wires in power distribution operations (including some power transmission operations), the existing grounding solders are difficult to install and even more difficult to pull out, and often break or even The phenomenon of discarded ground solder

[0003] Chinese patent application number 201420462776.0 discloses a grounding drill structure that is not easy to loosen and is easy to pull out, which increases the strength of the grounding drill to a certain extent. The rod is a cylindrical structure. Even if there is a hand-held structure on the frozen soil, it is extremely difficult to pull out the grounding drill by hand.

When drilling into permafrost, a sledgehammer is usually used. If the strength is not well controlled, it is easy to bend the drill, or directly damage the ground wire terminal board, or even damage the ground wire. The lack of identification is not conducive to detecting whether the ground drill is in place.
