Abstract
The utility model discloses a kind of earth potential dismounting screw tools for live working, solve the problem that prior art cannot carry out equipment screw in equal potential working dismounting charging operation, it comprises ratchet spanner, described ratchet spanner is furnished with both forward and reverse directions adjuster, arranges holder, at afterbody setting operation parts at the middle part of ratchet spanner; Described holder is flexibly connected insulating bar.The restriction of operating environment and space length is not subject to when the utility model uses, convenient operation, carrying portable, practical flexibly and field work safe reliable, one man operation can be carried out, ensure operating personnel and charging operation device security distance, greatly reduce equipment screw live-working safety risk and labour intensity in the equipotential dismounting charging operation of operating personnel.
Description
Technical field
The utility model relates to a kind of dismounting screw tool, particularly relates to a kind of device of earth potential dismounting charging operation power transmission and transforming equipment screw.
Background technology
At present; often have the situation that charging equipment loosened screw in operation causes equipment loose contact to be generated heat; in operation equipment long-term fever or temperature is too high all may scaling loss equipment, can complete rapidly smoothly heat generating spot screw dismounting or fastening be the key of abatement apparatus potential safety hazard.The upkeep operation method of tradition dismounting or holding screw has two kinds: one to be adopt common wrench dismounting or fastening operational method after equipment has a power failure, operation is simple, quick, and job safety there is very little risk, but equipment has a power failure and will bring the loss of electricity, affects power delivery and power supply reliability; When another kind is equipment live operation, operating personnel enters highfield and adopts spanner dismounting or fastening Equipotential live working method close to equipment, operating personnel must wear a complete set of screening clothing and carry out equal potential working, labour intensity is larger, and certain safe distance over the ground and space must be kept, run into narrow space or the special circumstances such as distance to the ground is inadequate time, especially, when the facility environment such as transformer station, switchyard is compact, the method cannot be adopted to carry out upkeep operation.
Summary of the invention
The purpose of this utility model is to solve in the charging operation such as transformer station, switchyard facility compact, narrow space and will to keep a safe distance etc. and cannot carry out an equipment screw difficult problem in equal potential working dismounting charging operation, a kind of earth potential dismounting screw tools for live working is provided, be not subject to the restriction of operating environment and space length, convenient operation, carrying portable, practical flexibly and field work safe reliable, can one man operation be carried out, greatly reduce equipment screw live-working safety risk and labour intensity in the equipotential dismounting charging operation of operating personnel.
The utility model comprises ratchet spanner, and described ratchet spanner is furnished with both forward and reverse directions adjuster, it is characterized in that: arrange holder at the middle part of ratchet spanner, at afterbody setting operation parts; Described holder is flexibly connected insulating bar.
Described insulating bar top is provided with connector, and connector and holder all have connecting hole, and bolt is fixed through connecting hole nut.
Described functional unit comprises load draw ring, insulating cord, and insulating cord connects load draw ring.
Described insulating cord one end is with the insulation rope sling be connected with the load draw ring that ratchet spanner afterbody welds.
Described both forward and reverse directions adjuster can adjusting elasticity screw direction, effectively can ensure ratchet spanner load dismounting screw; Described holder its excess-three face except the solder side welded with ratchet spanner is polished as smooth arc surface, reduces ratchet spanner rotational resistance.
Operation principle of the present utility model: insulating bar is fixed on ratchet spanner holder by connector, pull the functional unit of ratchet spanner afterbody, as the insulating cord that load draw ring connects, ratchet spanner rotates parbuckle screw under leverage, realizes the dismounting that in running, charging equipment is tightened up a screw.
The beneficial effects of the utility model: through field test repeatedly with improve and optimizate proof, the restriction of operating environment and space length is not subject to when this instrument uses, convenient operation, carrying portable, practical flexibly and field work safe reliable, one man operation can be carried out, ensure operating personnel and charging operation device security distance, greatly reduce equipment screw live-working safety risk and labour intensity in the equipotential dismounting charging operation of operating personnel.
