Abstract

The utility model discloses a portable short-circuit grounding wire device, which belongs to grounding tools during high-voltage circuit maintenance and structurally at least comprises a wire clamp for clamping a wire and being connected with a grounding wire and an insulating operation rod connected with the lower end of the wire clamp. The lower end of the wire clamp is connected with a cylindrical clamping head, and a clamping roller is arranged on the side face of the clamping head. The upper end of the insulating operation rod is connected with a magnetic clamping base with the inner diameter matched with the outer diameter of the clamping head, and a clamping opening which achieves clamping connection and is matched with the clamping roller is arranged on the lateral wall of the magnetic clamping base. The wire clamp and the insulating operation rod achieve detachable connection in a clamping mode, the insulating operation rod can be taken down after the wire clamp is fixed to the wire, users enable the insulating operation rod to be connected with the wire clamp after the overhaul is finished, and the wire clamp is taken down from the wire. Accordingly, influence caused by the insulating operation rod during the circuit overhaul process can be avoided, and safety accidents are better avoided.

Description

A kind of portable short-circuit grounding wire device

Technical field

Earthing tool when the utility model belongs to the high-tension circuit maintenance is specifically related to a kind of carry-along short-circuit grounding wire device.

Background technology

In the maintenance process of high-tension circuit, for maintainer's personal safety, need to overhaul the down circuitry of part usually, and on the circuit of maintenance, connect the short-circuit grounding wire device high-voltage line ground connection, prevent that circuit incoming call or electric leakage etc. suddenly from causing the accident.Yet the short-circuit grounding wire device of prior art mostly is the structure that adopts integral type; The hook stick that just will insulate is fixedly connected on the lower end of ply-yarn drill; In the maintenance circuitry processes; The insulation hook stick of short-circuit grounding wire device is suspended on ply-yarn drill below, hinders service work, and unexpected easily touching insulation hook stick and cause the ply-yarn drill that blocks electric wire that is connected with the hook stick that insulate to become flexible even fall and the accident that meets accident.

Summary of the invention

The purpose of the utility model is: the short-circuit grounding wire device that provides a kind of ply-yarn drill and insulation hook stick can be for convenience detach or to be connected, and to overcome the deficiency that prior art exists.

For realizing the purpose of the utility model; Adopt following technical scheme to be achieved: to comprise at least being used for clip on electric wire and be connected with the ply-yarn drill of earth lead; And the insulation hook stick that is connected with the ply-yarn drill lower end; Described ply-yarn drill lower end is connected with columniform dop, and the dop side is provided with the card rod; Described insulation hook stick upper end is connected with the magnetic deck that internal diameter and dop external diameter are complementary, and magnetic deck sidewall offers and block the bayonet socket of the realization clamping that rod is complementary.

As preferred version: described insulation hook stick lower end is socketed with an electro-insulating rubber handle.

Compared with prior art; The beneficial effect of the utility model is: owing to be to realize removably connecting through the clamping form between ply-yarn drill and the insulation hook stick; After being fixed to ply-yarn drill on the electric wire, just can the insulation hook stick be taken off; The hook stick that will insulate again after extremely maintenance finishes is connected with ply-yarn drill, ply-yarn drill is taken off from electric wire get final product.So just avoid the influence that the insulation hook stick causes in the circuit maintenance process, avoided the generation of security incident better.

Embodiment

According to accompanying drawing the embodiment of the utility model is done a detailed explanation below.

According to illustrated in figures 1 and 2; The utility model structurally comprises at least and is used for clip on electric wire and be connected with the ply-yarn drill 1 of earth lead; And the insulation hook stick 4 that is connected with ply-yarn drill 1 lower end, described ply-yarn drill 1 lower end is connected with columniform dop 2, and dop 2 sides are provided with card rod 21; Described insulation hook stick 4 upper ends are connected with the magnetic deck 3 that internal diameter and dop 2 external diameters are complementary, and magnetic deck 3 sidewalls offer and the bayonet socket 31 that blocks the realization clamping that rod 21 is complementary.Wherein, magnetic deck 3 is in order to guarantee that it contacts with the tight of dop 2.As shown in Figure 2, the hook stick 4 as long as low-angle ground turn is insulated just can be realized itself and being connected or separating of ply-yarn drill 1 easily.

Described insulation hook stick 4 lower ends are socketed with an electro-insulating rubber handle 5.Like this, before the maintenance circuit, under the whether charged situation of unknown circuit, make the operation safe when being fixed to ply-yarn drill 1 on the electric wire.

Before the maintenance circuit; The hook stick 4 that will insulate earlier is installed on the ply-yarn drill 1; As shown in Figure 2; The dop of ply-yarn drill 1 lower end 2 is inserted in the magnetic deck 3 of insulation hook sticks 4 upper ends, clockwise rotate insulation hook stick 4 and make the card rod 21 of dop 2 snap in extending laterally part and can ply-yarn drill 1 being connected together with insulation hook stick 4 of bayonet socket 31, the hand-held then handle 5 that insulate hook stick 4 clips to ply-yarn drill 1 on the electric wire of Awaiting Overhaul; Then, rotating counterclockwise insulation hook stick 4 makes the card rod 21 of dop 2 and bayonet socket 31 disengagings of magnetic deck 3 can take off insulation hook stick 4.After treating that line maintenance finishes, adopt the said method hook stick 4 that will insulate to be connected with ply-yarn drill 1, the use hook stick 4 that insulate takes off ply-yarn drill 1 and gets final product from electric wire then.

Like this, in the process of maintenance circuit, have only ply-yarn drill 1 to be clipped on the electric wire, can not make ply-yarn drill 1 break away from electric wire and cause the accident because of accident touching insulation hook stick 4.
