Description
Technical field
The utility model relates to power circuit maintenance tool, particularly relates to a kind of tension-resistant rod track replacement stockbridge damper aid.
Background technology
The effect of the meteorological conditions such as overhead power line wind-engaging, ice, low temperature, makes circuit produce vibration and dynamic dance.Vibration frequency is higher and amplitude is very little, and wind vibration makes overhead wire at suspension point place repeatedly by stubborn folding, causes fatigue of materials, finally causes disconnected stock, line-outage contingency.The frequency of waving is very low, and amplitude is very large, long vibration is easy to cause wire fracture, alternate flashover, cause line tripping, have a power failure or the serious accidents such as wire of burning, therefore, higher at shaft tower, the overhead power line that span is larger needs stockbridge damper is installed, stockbridge damper can absorb or damping vibration energy, change circuit wobble frequency, prevent the vibration of circuit or wave, stockbridge damper is all-metal construction, comprise the aluminium armor tape of guardwire, the wire clamp of fixing cord, steel strand wire, and the symmetrically arranged hammer body in steel strand wire two ends, general weight is at about 2.2 kilograms, because the overhead transmission line long term exposure that stockbridge damper is installed in atmosphere, stockbridge damper very easily damages or aging, sometimes also can offset, in order to circuit normal operation and prevent aging stockbridge damper falling from high altitude from hurting sb.'s feelings, need to regularly replace stockbridge damper, straight line pole circuit close together, change relatively easily a bit, and the mode that existing tension-resistant rod circuit (as shown in Figure 1) changes stockbridge damper comprises: 1, staff's body carries kit on the arm, step on bar to cross-arm, hitch security personnel's rope, trick cooperation straddles on strain insulator and wire, slowly move to stockbridge damper installation place, then posture is changed, toppling over health uses spanner etc. to change by transmitting the new stockbridge damper of rope transport, satchel, security personnel's rope waits interference walking, this kind of mode (the net training of general state is also adopt in this way) is very big to staff's physical demands, psychological pressure is overweight, security risk is very high, 2 move to stockbridge damper installation place by the tightrope ladder that cross-arm and wire are connected, rope ladder swings, there is security risk equally: 3, in the level land circuit that shaft tower is not very high, by aerial lift device with insulated arm, staff is delivered to stockbridge damper installation place, changes, although this mode is changed fast, but limit by landform, aerial lift device with insulated arm can not arrive the extreme terrain such as mountain region, the woods, limits its use.
Utility model content
For Problems existing in tension-resistant rod track replacement stockbridge damper in above-mentioned prior art, the utility model provide a kind of reliable and stable, coefficient of safety is high, save muscle power tension-resistant rod track replacement stockbridge damper aid.
The technical scheme that problem to be solved in the utility model is taked is: tension-resistant rod track replacement stockbridge damper aid, comprise symmetrically arranged side lever, the bottom of side lever is provided with safety net, one end of side lever is provided with the U-shaped grapple being fixed on cross-arm, the other end of side lever is connected with wire fixer, the side of described wire fixer has metallic channel, is provided with some lateral step and instrument cases between described side lever, lateral step is provided with anti-slip veins.
The utility model has the advantages that: 1, by using the utility model to change stockbridge damper, on line, walking is convenient, and simple declaration can operate, easy accessibility, greatly reduces the physical demands of staff; 2, by the cooperation of U-shaped grapple and wire fixer, form triangle robust structure, alleviate the psychological pressure of staff; 3, arrange instrument cases, staff does not need to carry with satchel, alleviates heavy burden, interfering line is not walked.
Accompanying drawing explanation
Fig. 1 is the structural representation of strain insulator overhead transmission line,
Fig. 2 is structural representation of the present utility model.
In the drawings, 1, electric pole 2, cross-arm 3, strain insulator 4, stockbridge damper 5, wire 6, U-shaped grapple 7, lateral step 8, anti-slip veins 9, wire fixer 10, metallic channel 11, instrument cases 12, side lever 13, safety net.
Embodiment
In order to make those skilled in the art understand the technical solution of the utility model better, in conjunction with embodiment, the utility model is described in further detail with reference to the accompanying drawings below.
As shown in Figure 2, tension-resistant rod track replacement stockbridge damper aid, comprise symmetrically arranged side lever 12, the length of side lever is roughly equal to the distance of stockbridge damper with cross bar, can slightly grow a bit, side lever is cylindrical, step on sky when walking to prevent staff to fall, the bottom of side lever is provided with the safety net 13 of circular arc, safety net adopts insulated high-strength wear-resisting rope to make, one end of side lever is provided with the U-shaped grapple 6 on fixing cross-arm, the other end of side lever is connected with wire fixer 9, the hollow circular shape of the wire fixer side of being body, the side of described wire fixer has metallic channel 10, in order to better secure wires, the position of metallic channel is preferably positioned at mid point position on the lower side, wire fixer side, some lateral step 7 and instrument cases 11 are provided with between described side lever, instrument cases there is knob (not marking in figure), spanner can be deposited, the light instruments such as aluminium armor tape, in order to normally work in sleet sky, lateral step is provided with anti-slip veins 8.
During use, first have a power failure, staff carries transmission rope on the body and climbs up electric pole 1 to cross-arm 2 position along climbers, after carrying out ground connection and electrical verification work, fasten security personnel's rope, ground staff ties up admittedly good aid, on bar, staff uses and transmits rope lifting aid, being grasped by hook fixes on cross-arm, by metallic channel, wire is fixed tightly in wire fixer, first step on step in advance and check steadiness between three fixing points, then hand grabs strain insulator 3 or wire 5 slowly moves to stockbridge damper 4 place, then from feed cassette, spanner and aluminium armor tape etc. is taken out, pull down the stockbridge damper that need change, the mark original position of stockbridge damper, after the stockbridge damper more renewed by transmission rope, parcel aluminium armor tape (preventing from damaging wire), fastening stockbridge damper wire clamp, check errorless after then return cross-arm position, ground transferred by dismounting aid, pull down earth connection, then lower beam, in aforesaid operations, staff can steadily walk on aid, and physical demands is little, without larger psychological pressure, proved by practical operation, efficiency improves more than twice.
Above execution mode is only in order to illustrate the technical solution of the utility model and unrestricted; although be described in detail the utility model with reference to specific embodiment; those of ordinary skill in the art is to be understood that; can modify to the technical solution of the utility model or equivalent replacement; and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the scope of claim of the present utility model protection.
