Background technology
Design for tension-resistant rod steel tower form using dry font, its shaft tower height are substantially exhausted in more than 40m, middle phase conductor Edge uses double insulator string, and structure length is in 2400mm or so.To ensure the safe operation of power grid, power supply reliability is improved, The powered work team that transmits electricity is required on the type shaft tower repeatedly carry out equipotential live-line maintenance operation every year.Such as:Equipotential is more Change the work such as strain insulator, equipotential adjustment damper, equipotential processing foreign matter.Because insulator chain length is too short, between combination Gap cannot meet " across the requirement that two short three " enter electric field, simultaneously because iron tower structure limits, can not install by insulator chain The common hard ladder of dielectric level carries out potential transfer.At present, equipotential live line work part is carried out on such shaft tower and uses insulated flexible ladder Or method of playing on a swing enters electric field, since shaft tower height is high, rope ladder hitch point is high, and physical demands is very when equipotential electrician climbs Greatly, when equipotential electrician is swung into below hitch point by tower body, rotation and shaking amplitude are big, to equipotential electrician psychology, muscle power and Technical requirements are high, and a whole set of operational method operating efficiency and safety coefficient are relatively low.
Utility model content
The purpose of the utility model is to overcome in place of the deficiencies in the prior art, and provide a kind of equipotential live line work personnel into Go out the instrument of electric field, its efficiently solve conventional 220V do equal potentials operation in font strain rod tower can not realize or operation in Safety coefficient during equipotential live line work redundant labor transfer current potential, the problem of operating efficiency is low, while the set instrument is convenient for disassembly and assembly, light weight It is full of, operational method is simple and safe, and technical requirements are low.
Phase transfer current potential power tool in a kind of dry font anchor support, includes insulated centipede, insulated ladder, is insulating The one end of flat ladder is provided with a ratchet, a fixed seat is additionally provided with ratchet shaft, the fixed seating is on ratchet shaft It can be rotated around ratchet shaft, the hole for insulated centipede insertion is provided with fixed seat, insulated centipede is inserted into fixed seat Hole after be threadedly coupled part locking, the sidepiece of fixed seat is provided with the hole seat for installing pawl, one end of hole seat is opposite Ratchet, when insulated ladder and insulated centipede angular adjustment are fixed, pawl is pinned by being stretched out in hole seat in the groove for snapping into ratchet, It is exposed in pawl and the locating rod perpendicular with it is provided with the other end of hole seat, is provided with the one side wall of hole seat respective end One open slot, its pawl is just against in ratchet slot when the locating rod on pawl is caught in open slot, has locating rod in pawl That one end is provided with link, and fixed pulley is provided with insulated centipede, and the one end for the drawstring that insulate is connected on link, the other end Around the control that pawl is realized after fixed pulley, resetting spring is provided with pawl, the upper end of insulated centipede is provided with connection Hook.
The spring being connected with pawl is internally provided with fixed seating, promotes pawl to work as insulation to ratchet slot direction stress When rope does not exert a force pawl link, the locating rod on pawl is caught in open slot, and pawl is snapped into the groove of ratchet by being stretched out in hole seat Locking, two-section ladder angle is fixed at this time.When insulating cord exerts a force pawl link, locating rod is left open slot, be can adjust at this time Two-section ladder angle.The spring set inside fixed seating can prevent pawl from deviating from from fixed seating.
The hook of the connection hook with blocking device.
The connection hook is linked up with using blocking device, ladder hook using high-strength alloy, stainless steel material After being connected stress with conducting wire can close locking, when dismounting automatically opens up.
Fixed seat is structure as a whole with hole seat.
In summary, the utility model following advantage compared with prior art:
Kit is convenient for disassembly and assembly, and quality is slim and graceful, and operational method is simple and safe, is suitable for the strain rod tower in different structure Upper progress equipotential personnel's potential transfer;The close locking of energy after ladder connection hook is connected stress with conducting wire, when dismounting, beat automatically Open;Operating personnel by insulating cord can remote control and regulation pawl and ratchet card slot state, and then adjust the angle between two section ladders Degree;Transfer current potential is realized by the binodal ladder angle adjustable that insulate, efficiently solves the equal potentials in dry font strain rod tower Safety coefficient in operation, the problem of operating efficiency is low, a kind of new way of equipotential disengaging electric field is opened up.
