Device.
Background technology
With the continuous expansion of China's power grid scale, transmission voltage grade and conducting wire distance to the ground are continuously improved, power transmission line
The task that road maintenance undertakes is also increasingly heavier, and power transmission lines overhauling operating personnel can only enter conducting wire to distance by climbing rope ladder
From 40 meters transmission lines of electricity below are overhauled, and the transmission line of electricity of 40 meters of conducting wire distance to the ground or more cannot then pass through rope ladder method
Into site examining and repairing, because not only taking people, laborious but also be extremely unsafe operational method apart from excessively high.In particular with me
Building up successively for state's extra-high voltage grid puts into operation, and new requirement is also proposed to the repair method of UHV transmission line, every at present
When secondary tangent tower livewire work, it can only enter highfield by swinging in method, and cannot pass through tradition that operating personnel, which enters conducting wire,
Method enters by rope ladder, the overall qualities requirement which increases the limitation of operation and to operating personnel.
And the operational method for entering highfield by rope ladder is easy, safe, easy to operation, why cannot be in extra-high crimping
Road uses, and main cause is that extra high voltage line distance to the ground is excessively high (minimum 40 meters, 100 meters of highest or more), and operating personnel can not
Normal climbing enters operation field, significantly limits the selectivity to extra high voltage line hotline maintenance method.In order to guarantee I
The hotline maintenance of state's extra-high voltage grid, it is necessary to design a kind of transmission line of electricity speed governing rope ladder climbing device, be the inspection of extra-high voltage grid
It repaiies and livewire work method is improved and provides new operation means.Transmission line of electricity speed governing rope ladder climbing device is still in blank and leads at home
Domain needs further to research and develop and test.
Invention content

Speed motor is separately fixed on upper mounting plate and lower installation board, and the output shaft of DC speed-regulating motor and the input shaft of gearbox pass through
Shaft coupling connects, and perpendicular to ground, two output shafts of gearbox on same level axis and turn to the input shaft of gearbox
It is identical, it is respectively fixed with a nylon roller on the overhanging end of two output shafts of gearbox and forms nylon capstan winch；Two thoroughly do away with
The upper end of edge rope is vertically hung on by insulating cord hanger on conducting wire, and every insulating cord is after the string holes on upper mounting plate corresponding
Be pierced by again from the string holes on lower installation board after 4 to 6 circles on the nylon roller of position, the lower end of every insulating cord by earth anchor and
Tensioned lines are fixed on ground；Described control unit and power supply are respectively and fixedly installed to the upper and lower part of climbing device framework, control
Unit includes power switch, reversing switch and speed-regulating switch, and reversing switch and speed-regulating switch are used for the steering of DC speed-regulating motor
And adjustment of rotational speed；
The gearbox is the turbine and worm reduction box of uniaxial drive twin shaft output；
Upper mounting plate and lower installation board both sides be respectively set there are one for insulating cord by string holes, in upper mounting plate and
The string holes of lower installation board homonymy is one group, and the position of every group of string holes is corresponding with the position of the nylon roller of homonymy, every group upper
Lower two string holes are located at the upper and lower part of homonymy nylon roller, and lower in vertical direction pair of upper and lower two string holes
In；
The tensile force of tensioned lines is adjusted by the tightener in tensioned lines, it is about 40 kilograms to make tension on every insulating cord.
It is an advantage of the invention that：
1) safety requirements and overall qualities requirement that operating personnel enters operation field are reduced, it is intrinsic to break transmission line of electricity
The operating type that can only enter straight line pole operation field by swinging in method, founded a kind of the new of power transmission lines overhauling operation
Method.
2) present situation that traditional approach relies on talent's climbing has been broken, has ensured that operating personnel enters operation field and there can be abundance
Physical efficiency, climbing device used electronic mode, can be entered operation field with most fast speed, significant increase operating efficiency.
3) applicability is wider, can be applicable in all overhead transmission lines.Broken conducting wire distance to the ground more than 40 meters and
It cannot directly enter the operational method of site examining and repairing.
4) higher safety and reliability can significantly more efficient reduction operation wind using speed governing rope ladder climbing device equipment
Danger promotes the security management and control to operation；Lifting means reliability.
