Abstract
The present invention relates to a kind of slip-off preventing ground clamp, be mainly used in hanging of earth connection in site safety measure, in the process that ground wire hangs, play the effect preventing ground wire from coming off.Its body design becomes question mark shape, and the opening part activity of question mark shaped body arranges stop, and stop is connected with body by connecting rod, and the main locking relying on disc stop to realize opening, by the compounding practice of insulating bar joint, realizes locking limit function.After this design ensures that ground wire hangs, be positioned at ring seal space, and unique outlet is closed, do not increasing workload, while not increasing the difficulty of work, fundamentally stopped the possibility that ground wire comes off, ensure that the personal safety of maintainer.
Description
Technical field
The present invention relates to a kind of ground clamp of electric power system, particularly relate to a kind of slip-off preventing ground clamp, be mainly used in site safety measure arrange in the hanging of earth connection, belong to electric power application.
Background technology
In the activity in production of power supply enterprise, the mounting arrangements of safety measure is the important step ensureing safety, and wherein hanging of ground wire is the important measures ensureing line construction personnel and maintainer's personal safety, is the most important thing of preparation before maintenance.Draw if bus is disconnected, ground wire comes off, and will cause human body electrification, can cause immeasurable loss.But in prior art, often due to wind pendulum or the disconnected situation of the reason such as to draw and occurring coming off, there is potential safety hazard in earth connection.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, provide a kind of slip-off preventing ground clamp, solve earth connection in prior art easily to come off, there is the problem of potential safety hazard, the present invention is connected in ground clamp by solid and reliable for wire, fundamentally stop the possibility that earth connection comes off, ensure that the personal safety of upkeep operation personnel.
Technical scheme of the present invention is as follows:
Slip-off preventing ground clamp, body design becomes question mark shape, and the opening part activity of question mark shaped body arranges stop, and stop is connected with body by connecting rod.
Described inner body wall is provided with spring clip.
Described body lower part is that hollow is arranged.
Described stop is disc.
Described connecting rod comprises three joints, one end of first segment connecting rod is connected with stop, the other end of first segment connecting rod is connected with one end of second section connecting rod, and the other end of second section connecting rod is connected with one end of Section of three connecting rod, and the other end of Section of three connecting rod connects contact plate.
Described first segment connecting rod is connected by spring with body.
Described second section connecting rod is connected with body by its central shaft.
Be provided with limit spring between the top of described contact plate and body hollow region, contact plate is provided with latch contact.
Advantageous effect of the present invention is as follows:
1, after ensureing that ground wire hangs, be positioned at ring seal space, and unique is gone out atretostomia, fundamentally stop the possibility that ground wire comes off.
2, the present invention just changes the function of ground clamp, does not change the method for operation that ground wire hangs, can not affect operating efficiency.
3, ensure fastness, reliability that ground wire hangs, make earth connection due to wind pendulum or the disconnected situation of the reason such as to draw and occurring coming off, the personal safety of maintainer can not be ensure that.

Embodiment
Referring to accompanying drawing, in conjunction with specific embodiments, the present invention is described in detail.
Embodiment
As shown in Figure 1, slip-off preventing ground clamp, body 6 is designed to question mark shape, and the inwall of question mark shaped body is provided with spring clip 1, and body lower part is that hollow is arranged; The opening part activity of body arranges disc stop 2, and disc stop 2 can be movable in the certain limit of body; Stop is connected with body by connecting rod 3; Described connecting rod comprises three joints, and one end of first segment connecting rod is connected with stop, and the other end of first segment connecting rod is connected with one end of second section connecting rod, the other end of second section connecting rod is connected with one end of Section of three connecting rod, section three, the other end of connecting rod connects contact plate 4, be used for control link activity; Described first segment connecting rod is connected by spring 7 with body; Described second section connecting rod is connected with body by its central shaft; Be provided with back-moving spring 8 between described contact plate 4 and the top of body hollow region, contact plate can be up and down in hollow region, resetted by back-moving spring, and contact plate is provided with latch contact 5.
Also can slightly adjust with body matching used insulating bar connector structure, but adjust structure can not use as usual yet.Better effects if after adjustment, the structure after its adjustment is, insulating bar connector is under the constant prerequisite of original joint geometry, and within a fitting, position arranges the cylindrical projections matched with contact plate size.
When earth connection hangs, when insulating bar connector is connected with ground clamp body, insulating bar contacts with latch contact 5, and unlocking contact 5 is for the one direction locking of contact plate 4.In insulating bar and ground clamp connection procedure, insulating bar promotes contact plate 4 and moves upward, and by connecting rod 3, is pulled downwards by stop 2, and question mark shaped opening part is opened wide, and wire can enter the clamping of ground clamp body from opening part.After insulating bar is extracted, due to action of reset spring, stop 2, contact plate 4, latch contact 5 are resetted, opening is sealed, simultaneously by the locking of contact plate 4 one direction, prevent opening part from opening wide.Ground wire demolishing process is similar with installing process.
The above know-why being specific embodiments of the invention and using, any based on the equivalent transformation on technical solution of the present invention basis, all belong within protection scope of the present invention.
Claims (7)
1. slip-off preventing ground clamp, is characterized in that body design becomes question mark shape, and the opening part activity of question mark shaped body arranges stop, and stop is connected with body by connecting rod; Described connecting rod comprises three joints, one end of first segment connecting rod is connected with stop, the other end of first segment connecting rod is connected with one end of second section connecting rod, and the other end of second section connecting rod is connected with one end of Section of three connecting rod, and the other end of Section of three connecting rod connects contact plate.
