Description

A kind of link rod of Electrified fastening screw
Technical field
The utility model belongs to power domain, especially relates to a kind of link rod for high tension overhead transmission line Electrified fastening screw.
Background technology
Overhead transmission line due to its junction of long-time running unavoidable appearance loosen, gap, junction increase, new line build or old line maintenance fitting process in, screw install not in place, there is gap in gold utensil; Corner pole is in the gold utensils such as the effect tension folder of angle for a long time and occurs that distortion causes loosened screw wherein, there is the reasons such as gap between gold utensil, capital occurs that capacitor discharge scene causes connecting position of wires gold utensil temperature to raise the lighter and can injure the generation that wire severe one can cause line-outage contingency, transmission line is that major network just causes large-area power-cuts to affect power supply reliability once line outage, so process conductor joint heating problem is exactly a considerable job.
General employing at present has a power failure and processes this type of defect, but, electric power is the important foundation industry of national economy and social development, along with the development of economic society, national economy and the degree of dependence of the lives of the people to supply of electric power more and more stronger, more and more higher to the requirement of power supply reliability, the economic loss that power failure causes is also increasing.This type of defect of process that has a power failure so special is more and more unrealistic, and this type of conductor joint heating problem of on-line treatment also exists following problem:
1. adopt equal potential working method, equal potential working personnel wear screening clothing and enter electric field metal spanner holding screw to process conductor joint heating problem along insulator string (being only limited to the two insulator string of strain rod tower), this mode is high to staff's physical fitness requirement, operating risk is large, and operational security is low;
2. adopt equal potential working method, it is that instrument enters electric field, this operating type under the cooperation of electrician such as the face of grade with insulated flexible ladder that equal potential working personnel wear screening clothing, although risk reduces still operation but requires that personnel are many, instrument is many, and workload is large, and operating personnel has a strong constitution.Its limitation be on the circuit tightly playing type shaft tower or the arrangement of double back upper, middle and lower mutually and middle due to safe distance inadequate, the electric operating condition of discontented foot straps;
3. adopt earth potential working method, metal spanner is tied up on insulating bar with circle silk or cord by earth potential working personnel, carries out fastening work to the screw that gold utensil loosens down keeping a safe distance with electrified body.Shortcoming: instrument is coarse, coefficient of safety is low, can only be used for shirtsleeve operation, and firmly excessive to cause the connection of spanner and insulating bar to occur loosening, and serious spanner and insulating bar depart from thus cause falling object from high altitude to hamper normally carrying out of operation.
Therefore, research and develop a kind of link rod of Electrified fastening screw, both can carry out defect elimination under the state do not had a power failure, workload can be reduced again, increase job safety coefficient, on-line treatment be carried out to terminal heating problem and has very important significance.
Summary of the invention
In order to overcome above problem, the utility model provides a kind of link rod of Electrified fastening screw, and technical scheme is as follows:
A link rod for Electrified fastening screw, the utility model is characterised in that, comprises link rod and ratchet spanner handle; Offer nipple in the termination of link rod, be connected to junction button in ratchet spanner handle, at its lower end by bolt hinge, be provided with screw rod joint in junction button bottom; Be provided with the axle center sleeve vertical with link rod at ratchet spanner handle upper portion, in the cylinder of sleeve, be set to interior hexagon.
The utility model offers connecting hole at ratchet spanner handle upper portion, is provided with the threaded connecting pin of a head, inserts connecting hole by connecting pin in the rear end of sleeve, adopts nut to be fastened on ratchet spanner handle by sleeve.
The utility model ratchet spanner handle adopts insulating material, preferred epoxy.
Described sleeve can be dismantled, and according to use bolt size, changes corresponding large small sleeve.The raw material of sleeve are metal.
Described ratchet spanner handle should select the good material of insulation property to make, lightweight, convenient operation, glass mat or epoxy resin or polytetrafluoroethylene, preferred epoxy; Insulating material reason is adopted to be when holding screw, insulation distance between aerial condutor, shaft tower is not by shadow, effectively prevent the clearance of the tower and conductor that existing metal handle reduces virtually when operation, thus cause wire to the generation of shaft tower electric discharge hazard event.
Described bolt metal material makes, for connecting described junction button and ratchet spanner handle.
Described junction button metal material makes, and during work, is tightened by screw rod joint be connected with the nipple of link rod, and staff can stand and completes fastening bolt on the ground and process the work of conductor joint heating.
Described link rod can adopt joint formula (being applicable to 10kV ~ 35kV), two-segment type (being applicable to 110kV), three-section type (being applicable to 220kV), four joints formula (being applicable to 500kV) according to line voltage distribution grade.
The utility model compared with the existing technology, has the following advantages and beneficial effect:
1. prior art process terminal heating problem needs electrician on equipotential electrician, bar, ground electrician and work director more than totally 4 people, and adopt the utility model only to need work director and ground electrician 2 people just can work, number of work obviously reduces;
2. improve prior art process conductor joint heating problem and not only need insulating bar, and need the present situation of the various instrument such as insulated flexible ladder and insulating cord; Adopt the utility model, required Work tool only has a set of link rod and the telescopic insulating ratchet wrench after improving;
3. operational method is simple, and workload greatly reduces, and the operating time shortens, and facts have proved that the operating time reduces to present 5 minutes and can complete the fastening of 1 screw, largely improves operating efficiency;
4. the utility model has simple, the easy to use, safe advantage such as effectively of structure.The handle that insulating material makes is lightly flexible, and fail safe is high, practical; The improvement of this spanner saves manpower, decreases operating time and workload, has saved operating cost; Work tool carries, easy to install and use, practical, security performance is good, reduces the risk that working method is in the past brought.
