Abstract

An overturn-type grounding wire clamp comprises a wire clamp body, an elastic tensioning mechanism, a slide rail, a slide block, a push rod, an insulation rope installation ring and a grounding wire installation hole. The connection mode is as follows: the wire clamp body is formed by a first wire clamp clamping block and a second wire clamp clamping block; the first wire clamp clamping block and the second wire clamp clamping block form an opening in the upper portion and form a wire clamping portion in the middle; and the elastic tensioning mechanism is arranged between the lower portions of the first wire clamp clamping block and the second wire clamp clamping block to realize the opening and closing of the wire clamp body. The push rod is arranged between the wire clamping portion and the elastic tensioning mechanism. One end of the push rod is hinged to the first wire clamp clamping block, and the other end runs through a through-hole arranged in the second wire clamp clamping block. When the wire clamp body opens, the push rod can support on the upper outer edge of the through-hole. The outer side of the first wire clamp clamping block is provided with the slide rail from top down, and the bottom of the inner side is provided with the grounding wire installation hole. The slide rail is provided with the slide block in sliding cooperation with the slide rail; and when the slide block slides to the bottom of the slide rail, positioning can be achieved. Compared with the prior art, the grounding wire clamp is easy to operate; an operating lever is not needed; the grounding wire clamp is light in weight and convenient to carry; and wind has little influence on the grounding wire clamp.

Background technology

Hanging earthing conductor is important measures in technical safety measures in power circuit operation maintenance.Set out ground wire on the power circuit that uses suspension insulator time, there is following problem: the earth connection overall weight that uses insulating bar to operate is larger, carries inconvenience.In the time of the two enterprising line operate of multi-loop line of wiring on the same tower, opereating specification is larger, has unsafe factor.The earth connection that uses soft material to operate is in operation, is subject to operating personnel's skilled operation degree and environmental impact, affects operating efficiency.

Utility model content

The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of simple in structure, easy to operate, time saving and energy saving and convertible earthing clamp is safely and efficiently provided.

The technical solution of the utility model is: comprise wire clip body, elastic tension mechanism, slide rail, slide block, push rod, insulating cord installing ring and earth connection installing hole, connected mode is as follows: described wire clip body is made up of the first wire clamp fixture block and the second wire clamp fixture block, and opening is formed at the two top, middle part forms the opening and closing of between wire clamping part, bottom, elastic tension winding machine wire clip body being installed; Between described wire clamping part and elastic tension mechanism, push rod is installed, one end of described push rod is hinged on the first wire clamp fixture block, the other end runs through the through hole that the second wire clamp fixture block is provided with, and in the time that wire clip body opens, push rod can be supported on the outer, top of through hole; The bottom that the outside of the first described wire clamp fixture block is provided with top-down slide rail, inner side is provided with earth connection installing hole, and described slide rail is provided with the slide block being slidably matched with it, and described slide block slides to slide rail bottom and time can locate.

Such scheme can further be improved to:

Described elastic tension mechanism is made up of connecting bolt and spring leaf.

The bottom of described slide rail is the circular-arc of projection laterally.

Fixed locating stud in through hole on described the second wire clamp fixture block, and in the time that wire clip body opens, push rod can be supported on alignment pin.

Compared with prior art, the utility model is easy and simple to handle, without action bars, lightweight easy to carry, and is subject to windage little.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described further.

Referring to Fig. 1, a kind of convertible earthing clamp, comprise wire clip body, elastic tension mechanism 6, slide rail 9, slide block 1, push rod 5, insulating cord installing ring 8 and earth connection installing hole 10, connected mode is as follows: wire clip body is made up of the first wire clamp fixture block 7 and the second wire clamp fixture block 3, the two top forms opening 2, middle part and forms the opening and closing of between wire clamping part 4, bottom, elastic tension mechanism 6 being installed and realizing wire clip body, and elastic tension mechanism 6 is made up of connecting bolt and spring leaf; Between wire clamping part and elastic tension mechanism 6, push rod 5 is installed, one end of push rod 5 is hinged on the first wire clamp fixture block 7, the other end runs through on the through hole that the second wire clamp fixture block 3 is provided with, and in the time that wire clip body opens, push rod 5 can be supported on the outer, top of through hole; The bottom that the outside of the first wire clamp fixture block 7 is provided with top-down slide rail 9, inner side is provided with earth connection installing hole 10, the bottom of slide rail 9 is the circular-arc of projection laterally, slide rail 9 is provided with the slide block 1 being slidably matched with it, and described slide block slides to slide rail bottom and time can locate.

When use, first insulating cord is connected with insulating cord installing ring 8, and earth connection is connected with earth connection installing hole 10, then wire clip body is opened, and using push rod 5 supports to make to open part cannot be closed.By 1 stroke of slide block to wire clamp top (i.e. the first wire clamp fixture block 7 tops), wire clamp opening 2 upwards, pull control insulating cord wire is put into wire clamp opening 2, upwards draw insulating cord, wire presses push rod 5, wire clamp two fixture block closures are clamped wire by wire clamping part, complete earth connection and install.Loosen insulating cord slide block 1 and slide to wire clamp lower end along slide rail 9, now, draw insulating cord, be subject to slide rail 9 shape restrictions to draw piece and cannot get back to wire clamp upper end, and wire clamp to be subject to turning over turnback on backward to upper pulling force be that wire clamp opening 2 becomes downwards, on now continuing, draw insulating cord, wire backs down wire clamping part 4 and departs from by wire clamp opening 2, can complete earth connection dismounting work.

Embodiment 2
