Embodiment 1

[0026] A retractable ground wire with an insulated handle, such as figure 1 As shown, it includes a retractable three-stage insulating handle 2, a reel 3 located at one end of the insulated handle 2, a central shaft is fixed inside the reel 3, a rotating shaft is installed on the outside of the central shaft through a bearing, and multi-strand annealed copper wire 1 Wrapped with a transparent sheath and wound on the rotating shaft, one end of the annealed copper wire 1 protrudes from the reel 3 and then connects to the grounding wire clamp 5, which is directly fixed on the grounding device through bolts and nuts, and the annealed copper wire The other end of 1 passes through the insulating handle 2 and is connected to the wired terminal clamp 4. The rotating shaft stretches out of the reel 3, such as figure 2 As shown, the end of the rotating shaft is a hexagonal sleeve, and the rotating shaft is driven by a crank handle 6 with a hexagonal column at the end (or the end of th...

Embodiment 2

[0028] This embodiment has the same structure as Embodiment 1 except the following features:

[0029] Such as Figure 4 As shown, the insulating handle 2 is a three-stage telescopic rod, and its structure is: the insulating handle 2 includes a hollow top rod 23, a bottom rod 21 and a connecting rod 22, the top rod 23 is set in the connecting rod 22, and the connecting rod 22 is set in the Inside the bottom rod 21; the bottom rod 21 is provided with a screw rod 26 that is equal in length to the bottom rod 21 and has a screw thread on the outer surface. The bottom of the bottom rod 21 is provided with a bevel gear I24 fixed on the bottom rod 21. There is also a bevel gear II 25 cooperating with the bevel gear I 24, the central axis of the bevel gear II 25 extends out of the bottom bar 21 and the end of the central axis is a hexagonal sleeve (or the end of the central axis is set in the shape of a hexagonal column);

[0030] The connecting rod 22 is provided with the inner rod 2...

Abstract

The invention discloses a retractable grounding wire with an insulation handle, and relates to the field of connecting components hanging on overhead lines or the other suspension lines used for making conductive parts connected with one another. By means of the retractable grounding wire with the insulation handle, the problems that according to a throwing grounding wire, time and energy are wasted in the throwing process, or the personal safety is endangered due to violation of regulation, for example, the grounding wire is directly taken by a hand for installation are solved. The retractable grounding wire comprises an annealed copper wire and a grounding wire clamp fixed to one end of the annealed copper wire, and further comprises the telescopic insulation handle and a reel fixed to one end of the insulation handle; the annealed copper wire is wound in the reel, one end of the annealed copper wire is grounded through the grounding wire clamp, and the other end of the annealed copper wire is connected with a wire end clamp after passing through the insulation handle. The retractable grounding wire with the insulation handle is used for installing the throwing grounding wire.

Description

technical field [0001] The present invention relates to a connecting element for interconnecting conductive parts for hanging on an overhead line or other suspended line, and in particular to a retractable earthing wire with an insulating handle. Background technique [0002] At present, the grounding wires we use are mainly hanging type grounding wires. Due to the restrictions on the installation and removal of the grounding wires in the "State Grid Corporation of Electricity Safety Work Regulations", it is necessary to install insulating ropes on the grounding wires or use special insulation operations. Operate with an insulated rope and hang it with an insulating rope. Limited by the accuracy of the throwing and hanging, it is time-consuming and laborious. If you use an insulating operating rod to hang the grounding wire, the grounding wire often falls off from the operating rod, prolonging the time for installing the grounding wire. In order to save effort, the grounding...
