Abstract

The invention belongs to power line maintenance tools and relates to a barrier removing tool for power lines, in particular to a maintenance tool used in the line patrol process of the power lines. The barrier removing tool is characterized by comprising an insulating telescopic rod, a connector, an arc-shaped knife saw, a shovel blade, a rod and an inclined hook; the lower end of the connector is in threaded connection with the upper end of the insulating telescopic rod; the arc-shaped knife saw is welded to the left side face of the connector; the left lower portion of the arc-shaped knife saw is an arc-shaped knife edge; the right lower portion of the arc-shaped knife saw is arc-shaped sawteeth; the shovel blade is welded to the right side face of the connector; the edge of the shovel blade faces upwards; the lower end of the rod is in threaded connection with the upper end of the connector; the upper end of the rod is a conical head; the inclined hook is welded to the upper portion of the rod. The barrier removing tool can be used for removing both branches near wires and entangled objects on the wires of electric poles, can remove bird nests on power transmission facilities and can also break and remove ice on outdoor substation equipment.

Description

The circuit instrument of removing obstacles

Technical field

The invention belongs to power circuit maintenance tool, the maintenance tool particularly using when a kind of power circuit line walking.

Background technology

Along with the development of China's modernization construction, also development thereupon of power grid construction, but in actual line walking work, near branch cleaning electric wire, need to use different line walking cutter saws, realizes and the multi-mode operation such as hooks, saws, shovels, draws, cuts.

On power transmission and transformation line, usually can run into the defect that has twister on electric pole wire; these twisters have formed certain threat to electrical network and personal safety; if defect elimination just likely causes line short switch trip not in time; cause large-area power-cuts and human casualty accident, certainly will bring unnecessary loss and potential safety hazard to electrical network and the person and masses' property.

Outdoor type converting equipment is in outdoor operation throughout the year, enter winter, falling into of light rain or snow, by the sharply decline of temperature, its surface has one deck and freezes parcel, if do not removed, along with constantly falling into of snow-broth, its ice sheet can be thickeied gradually, not only can cause the dielectric strength of equipment to reduce; In addition may be because of the heavy burden of icing, cause the holding strength of insulating sleeve to decline, until damage.

Summary of the invention

The object of the present invention is to provide a kind of circuit instrument of removing obstacles, this instrument can be cleared up near branch electric wire, can clear up again the twister on electric pole wire, also can remove the bird's nest on power transmission facility, also can abolish the ice on outdoor type converting equipment.

The technical scheme that technical solution problem of the present invention adopts is: the circuit instrument of removing obstacles, is characterized in that: it comprises insulating telescopic bar, connector, arc knife saw, perching knife, bar, oblique hook; The bottom of connector is threaded with the upper end of insulating telescopic bar, and the left surface of connector is welded with arc knife saw, and the lower left quarter of arc knife saw is curved blade, and the right lower quadrant of arc knife saw is arcuate serrated; The right flank of connector is welded with perching knife, and the blade of perching knife upward; The bottom of bar is threaded with the upper end of connector, and the upper end of bar is conehead, and the top of bar is welded with oblique hook.

Tiltedly the angle between hook and bar is 15-35 degree.

The invention has the beneficial effects as follows: simple in structure, easy to use, be easy to carry, function is many.This instrument can be cleared up near branch electric wire, can clear up again the twister on electric pole wire, also can remove the bird's nest on power transmission facility, also can abolish the ice on outdoor type converting equipment.

Brief description of the drawings

Fig. 1 is the structural representation of invention.

In figure: 1-insulating telescopic bar, 2-connector, 3-arc knife saw, 4-curved blade, 5-arcuate serrated, 6-perching knife, 7-bar, the oblique hook of 8-, 9-conehead.

Embodiment

As shown in Figure 1, the circuit instrument of removing obstacles, it comprises insulating telescopic bar 1, connector 2, arc knife saw 3, perching knife 6, bar 7, oblique hook 8; The bottom of connector 2 is threaded with the upper end of insulating telescopic bar 1, and (connector and insulating telescopic bar are separable, be easy to carry), the left surface of connector 2 is welded with arc knife saw 3 (for arcuate structure), the lower left quarter of arc knife saw 3 is curved blade 4, the right lower quadrant of arc knife saw 3 is that (blade is for cutting off a little bit smaller branch, and sawtooth is for sawed-off larger branch for arcuate serrated 5; Blade and sawtooth are combined, mixed and use, its effect of removing obstacles is remarkable, and efficiency is high); The right flank of connector 2 is welded with perching knife 6, and the blade of perching knife 6 is (for sliding trackle branch upwards) upward; The bottom of bar 7 is threaded with the upper end of connector 2 (bar 7 is separable with connector, is easy to carry), and the upper end of bar 7 is that conehead 9 (can be used for inserting in twister, then left behind by oblique hook; Also can be used for the ice-spur cut on equipment, then insert in cut ice is pulled up by the left end of arc knife saw 3), the top of bar 7 is welded with oblique hook 8 (tiltedly the angle between hook and bar 7 is 15-35 degree).

Near branch cleaning electric wire: adopt arc knife saw 3, perching knife 6.

Twister on cleaning electric pole wire, the bird's nest on power transmission facility is removed: adopt bar 7, oblique hook 8.

Abolish the ice on outdoor type converting equipment: adopt the conehead 9 of bar 7, and the left part of arc knife saw 3.
