Problems solved by technology

[0003] In the winter permafrost and when the construction soil is hard, it is often difficult to nail the grounding drill into the grounding wire, and the grounding drill is easily damaged by a hammer. In this case, pulling out the grounding drill is more difficult than driving it in. more difficult things

Embodiment 1

[0059] Such as figure 1 As shown, this embodiment provides a grounding solder used in electric power construction, which includes a columnar solder body 100 . Wherein, the drill body 100 is sequentially composed of a wiring section 110, a threaded section 120, and a polished rod section 130 from top to bottom. The threaded section 120 is threadedly connected with a pull-out nut 140. Fitting tablet 150 .

[0060] In this embodiment, the connection section 110 is provided with a connection terminal 111, and the lower end of the polished rod section 130 is gradually reduced to form a tapered insertion end 131 with a taper of 1:11. The outer diameter of the polished rod section 130 is 0.1 mm larger than that of the threaded section 120. , the length ratio of the threaded section to the polished rod section can be 1:1, the surface of the threaded section 120 is carburized with a carburized layer with a thickness of 0.2, and the surface of the polished rod section 130 is nitrided w...

Embodiment 2

[0063] This embodiment provides a grounding solder used in electric power maintenance operations, which differs from Embodiment 1 in that: Figure 4 As shown, it is a schematic cross-sectional view of the polished rod section 130 in this embodiment. The polished rod section 130 is provided with 6 excavation grooves 410 uniformly distributed along the axial direction, and the depth of the excavation grooves 410 gradually becomes deeper from top to bottom. The deepest depth of 410 is 0.2-0.3 of the outer diameter of the polished rod section.

[0064] In addition, in this embodiment, the length ratio of the threaded section and the polished rod section can be 3:1, the surface of the threaded section 120 is carburized to form a carburized layer with a thickness of 0.5 mm, and the surface of the polished rod section 130 is formed by nitriding. The thickness of the nitrided layer is 0.6 mm, and the outer diameter of the pressed sheet 150 is 5 times the outer diameter of the polished...

Embodiment 3

[0066] This embodiment provides a grounding solder used in the distribution network lightning protection system, which differs from Embodiment 1 in that: Figure 5 As shown, it is a schematic cross-sectional view of the polished rod segment 130 in this embodiment. The side wall of the polished rod segment 130 is provided with four ribs 510 along the axial direction, and the cross-section of each rib 510 is configured as a triangle.

[0067] In addition, in this embodiment, the length ratio of the threaded section to the polished rod section can be 2:1, the surface of the threaded section 120 is carburized to form a carburized layer with a thickness of 0.3 mm, and the surface of the polished rod section 130 is formed by nitriding. The thickness of the nitrided layer is 0.4 mm, and the outer diameter of the pressed sheet 150 is 4 times the outer diameter of the polished rod section 130 .

Abstract

The present invention relates to an electric power construction and maintenance work tool and particularly related to a grounding drill rod for power construction operation. The grounding drill rod comprises a cylindrical drill rod body which comprises a wire connection section, a thread section and a rod section from top to bottom, the thread section is threadingly connected to a pull-out nut, and a pressing piece which is in axial sliding fit with the thread section is arranged under the pull-out nut. The grounding drill rod is easy to pull out.

Description

technical field [0001] The invention relates to a working tool for electric power construction and maintenance, in particular to a grounding solder used in electric power construction work. Background technique [0002] In electric power construction and maintenance work, in order to ensure the safety of construction and maintenance, the installation of grounding wires is an essential and important work item. In the workplace where there is no way to borrow on-site grounding wires, most of them use local use. The ground solder is grounded. Most of the existing grounding drills are steel drills with a pointed tip at one end, which are inserted into the ground by tools such as hammers to insert them into the ground, and are pulled out after the construction is completed. [0003] In the winter permafrost and when the construction soil is hard, it is often difficult to nail the grounding drill into the grounding wire, and the grounding drill is easily damaged by a hammer. In t...
