Description

The instrument of fixing clamper and method

Technical field

The present invention relates to a kind of instrument of fixing clamper.The invention still further relates to a kind of method of fixing clamper.

Background technique

In the operation of the daily circuit of power supply enterprise, increasing the circuit branch line is more common work, such as add " straight line distribution transforming ", " wiring ", " cable is stepped on bar " on the straight line electric pole; On end bar, add " end distribution transforming ", " cable is stepped on bar "; In cooperating engineering " tearing, build the extension bar joining seam open " etc.

10 kilovolts of present charged joining seam work are often undertaken by overhead vehicle insulating glove working system, in fact, the 10 KV corridor major parts in suburb afield in, though or parallel with road, but distance is far away.Narrow die Dorfstrasse and letter drag bridge that heavy the current of livewire work overhead vehicle is restricted.In addition, all kinds of overhead conductors overlapping, crisscross with the circuit corridor, the lane that the old city town is long neglected and in disrepair, lane all make the livewire work overhead vehicle work smoothly, and outmoded hook stick wire binding machine requires progressively to be eliminated owing to the electric device that can not satisfy increasing load current and unitize.Like this, limit the carrying out of charged joining seam operation to a great extent, and adopted scheduled outage.But scheduled outage makes on every side user even long line user all have a power failure again, the reliability of influence power supply, and also power failure work also can bring many electric systems operations, not only increased workload but also cause some unsafe factors.

The hook stick instrument of wire clamp class generally has three at present: Two bors d's oeuveres wire clamp, wire clamp mounting or dismounting bar and sleeve operating stem.Use these instruments to operate and have following drawback: need to use three hook sticks, and have only two workmans on the general electric pole during work, one hand can't be operated again, therefore needs frequent tool for transmitting, makes operation not only complexity but also inconvenience; It is very inconvenient by hook stick wire clamp to be installed on live wire, very high to operator's requirement; The sleeve hook stick does not have afterburning handle, can't guarantee the moment of torsion of bolt.

Summary of the invention

Technical problem to be solved by this invention provides a kind of instrument of fixing clamper, and it is simple in structure, and is easy to carry, and the present invention also provides a kind of method of fixing clamper, can make the joining seam operation can realize livewire work under without the situation of overhead vehicle.

For solving the problems of the technologies described above, the technological scheme of the instrument of fixing clamper of the present invention is, comprise body and inner hexagon spanner, described body two ends are provided with the wire clamp seat of arc, the wire clamp seat outside is provided with spring sheet, and the middle part rear side has the limit position part and the joining seam line pressure plate corresponding with it of arc, and the below, middle part of joining seam line pressure plate is provided with rotatable screw rod, described screw rod passes the screw of body lower end, and with the threads engaged of screw inboard.

The present invention also comprises the method with above-mentioned instrument fixing clamper, and its technological scheme is, comprise the steps,

(1) upper half part with wire clamp is installed in the wire clamp seat of body, and clamps with spring sheet;

(2) the joining seam line is placed on the wire clamp and the corresponding side of limit position part;

(3) rotating screw bolt makes joining seam line pressure plate that the extruding of joining seam line is fixed in the limit position part;

(4) be connected with upper half part with bolt lower half portion, but leave enough spaces in the middle of two-part of wire clamp wire clamp;

(5) body that will accompany the joining seam line is suspended on the long line, and long line is placed in an other side on the wire clamp;

(6) tighten with the bolt of inner hexagon spanner, make wire clamp clamp long line and joining seam line firmly wire clamp;

(7) screw rod of rotation body makes joining seam line pressure plate that the joining seam line is unclamped;

(8) body is moved up, wire clamp and body are broken away from.

The present invention reduces to two with operation tool by original three, carries and uses all very conveniently, makes the work that wire clamp is installed to carry out flexibly under the situation of not using overhead vehicle, has improved working efficiency greatly.
