Abstract

The utility model discloses an all-function grounding device, belonging to an electrical facility. The utility model is characterized in that one end of an insulated operation rod is fixedly connected with an all-function transmission turret, and the all-function transmission turret is connected with a helix wire nip; the other end of the insulated operation rod is provided with an external screw thread which is rotationally connected with a fixing device; the fixing device takes a circular buckle which can be rotationally connected on the external screw thread of the insulated operation rod; the circular buckle is provided with an insulated draught rope, and the tail end of the insulated draught rope is connected with a latch. The utility model is characterized in that the length of the operation rod is extended and the turret is rotated for 90 DEG in universally; the hanging connection is flexible and firm; the human body is unnecessary to contact with the grounding wire when in operation; the operators on the straight rod tower are protected remotely; the utility model is fixed on the operation rod through the rear draught rope, thereby avoiding the twist of the grounding wires and the falling of the insulated operation rod; and the all-function grounding device has the advantages of saving time and labor, flexible and easy use, and high safety factors when in use.

Description

Omnipotent grounding apparatus

Technical field

The utility model belongs to a kind of electric power facility, specifically a kind ofly is articulated in omnipotent grounding apparatus on the strain insulator lead, protection power industry staff construction safety.

Background technology

Existing earth connection equipment is when articulating the strain insulator lead, exist ground connection the end of a thread and poor wire connection, even the earth connection hair is given birth to the serious phenomenon that breaks away from lead, for guaranteeing that ground connection the end of a thread contacts with lead well, avoid the generation of above hidden danger, the operating personnel must articulate ground connection the end of a thread is vertical with lead, and at this moment, insulating rod also is suspended on the lead thereupon; But when removing earth connection,, could remove earth connection, perhaps directly earth connection is wrapped in during hanging earthing conductor and avoid insulating rod to fall on the insulating rod because insulating rod away from cross-arm, has only by pulling earth connection copper cash part.More than the operation human body all can inevitably touch earth connection, certainly will cause the operating personnel to have a potential safety hazard in hanging, disconnect the ground line process.Therefore, existing grounding apparatus exists following some problem: 1) have inevitable potential safety hazard; 2) the strain insulator lead can't normally articulate; 3) strain insulator shaft tower operation, working strength is big, coefficient of safety is low, break down easily; 4) articulate too near apart from setting; 5) the equipment scope of application is little.

Summary of the invention

The utility model is in order to overcome above-mentioned deficiency, but provide a kind of can be according to Field adjustment length, articulate firm, universally articulate flexibly, in operation human body can touch earth connection, and the distance protection straight line pole on personnel's the omnipotent grounding apparatus of operation.

For achieving the above object, the omnipotent grounding apparatus of the utility model comprises: spiral bayonet socket wire clamp, insulating bar, insulation pull rope, its technical scheme is: the affixed universal transmission rotary head of an end of insulating bar connects spiral bayonet socket wire clamp in this universal transmission rotary head again; The other end of insulating bar is provided with external screw thread, this external screw thread fixture that spins, described fixture is a ring-like button that can be screwed on the insulating bar external screw thread, the ring-like bar insulation pull rope of having buckled, and the tail end of this insulation pull rope connects a snap close.

Its beneficial effect is: 1) can extend or shorten the length of insulating bar according to the needs of field condition, to be suitable for the electric equipment of different electric pressures; 2) spiral bayonet socket wire clamp can firmly be detained dead lead, makes it the outside destroy power that can't come off under external force and meet non-artificial reasons such as storm such as prominent; 3) universal transmission rotary head an angle of 90 degrees and strain insulator lead articulate, and break through the problem that existing grounding apparatus can't articulate this class lead and also taken into account articulating of vertical wires straight line pole, but and the personnel of operation on the distance protection straight line pole; 4) the rear portion pull rope is used for this equipment is fixed on action bars, has avoided the winding of earth connection and falling of insulating bar.Can reach in the use save time, laborsaving, flexible, characteristics such as coefficient of safety height.

Description of drawings

Below in conjunction with accompanying drawing and preferred implementation the utility model is further elaborated.

Fig. 1 is the structural representation of the omnipotent grounding apparatus of the utility model;

Among the figure: 1-bayonet socket wire clamp, the universal transmission rotary head of 2-, 3-action bars, 31-addition rod, 4-connecting ring, the ring-like button of 5-, 6-pull rope, 7-snap close, 8-earth connection.

Embodiment

As shown in Figure 1, the omnipotent grounding apparatus of the utility model comprises: spiral bayonet socket wire clamp (1), insulating bar (3), insulation pull rope (6), its technical scheme is: the affixed universal transmission rotary head of an end of insulating bar (3) (2), connect spiral bayonet socket wire clamp (1) again in this universal transmission rotary head (2), universal transmission rotary head can be flexible the conversion all directions, bayonet socket wire clamp (1) can be articulated in from all directions articulate on the strain insulator lead; The other end of insulating bar (3) is provided with external screw thread, this external screw thread fixture that spins, described fixture is a ring-like button (5) that can be screwed on the insulating bar external screw thread, the ring-like bar insulation pull rope (6) of having buckled, the tail end of this insulation pull rope connects a snap close (7), and this snap close and pull rope can be fixed on this equipment on the object easily.

During use, earlier the earth connection (8) on the spiral bayonet socket wire clamp (1) is connected, again bayonet socket wire clamp (1) is articulated on the strain insulator lead and with it and screws, insulation pull rope (6) with the insulating bar tail end is connected and fixed then, this pull rope (6) and snap close (7) can be fixed on this equipment on the object easily, on the tower bar, have avoided the winding of earth connection and falling of insulating bar, can reach in the use save time, laborsaving, flexible, characteristics such as coefficient of safety height.

As improvement of the present utility model, the utility model also is provided with insulation addition rod (31) and connecting ring (4), described insulation addition rod (31) is that the front and back end all has and the same externally threaded stock of insulating bar, described connecting ring (4) is the wide ring with internal thread that can be screwed on the insulating bar end external screw thread, it is a stock that connecting ring (4) can and connect addition rod and action bars, make the utility model lengthening, to adapt to the operation site of long distance.More than 1.7 meters, use single insulating bar to get final product as its safe distance of the following electric equipment of 110KV; 220KV electric equipment safe distance reaches more than 3.5 meters, then the ring-like button (5) of action bars (3) end can be screwed off, addition rod (31) is connected to the male end of insulating bar (3) with connecting ring (4), ring-like button (5) is spun on the tail end of this addition rod (31), so the utility model action bars that prolongs can adapt to the operation site of 220KV electric equipment fully again.
