A kind of transmission line deicer
The present invention relates to a kind of power transmission lines overhauling device, particularly a kind of transmission line deicer.
For many years; Particularly 2008; A lot of local overhead transmission lines winter-spring season because of ice rain weather cause () the line icing, and taken place in succession conductor galloping cause and lead () broken string, gold utensil and the shaft tower of line damage even accident such as collapse, and causes large-area power failure; Lose great, and the safe and stable operation of serious threat electrical network.
Artificial de-icing method is also adopted in domestic powerline ice-covering removing work at present mostly; Adopt and artificially to knock or with mode deicing such as rifleries with excellent rod; Need more personnel's inputs and resources input like this and do not reach needed efficient, also be difficult to ensure deicing personnel's life security.Perhaps adopt the method for high-voltage line ice-melt, but high-voltage line ice-melt consumes energy too, and the energy consumption of application machine method deicing is much smaller than great current deicing.Great current deicing method efficient is higher, but costly, and complicated operation has considerable influence to system safety.

And described external gear left and right sides symmetric arrangement one external gear wheel roller, this external gear roller is connected through bearing on the inwall of shell, the contact-making surface of external gear and external gear roller is taper, and the vertex of a cone of external gear roller overlaps outside on the Gear axis.
And have bonnet to be arranged on an end of this transmission line deicer, and an end of this bonnet is connected on the outer wall of sun gear, and the other end is connected with shell.
One end of retainer is connected with shell through baffle plate; The other end cooperates with the inwall of bonnet through the retainer roller; Has groove on the contact-making surface of baffle plate and retainer; Have ball to be arranged in this groove, the contact-making surface of retainer roller and bonnet inwall is taper, and the vertex of a cone of retainer roller overlaps on the sun gear axis.
And on the planet pin symmetric arrangement three pairs of bearings, inboard pair of bearings cooperates with external gear, the pair of bearings of centre cooperates with sun gear, the pair of bearings in the outside cooperates with retainer.
And described sun gear, retainer, shell, bonnet fasten by two parts up and down and form, and connect respectively through alignment pin.
And drive motors is connected on the shell through cover plate.
The invention has the advantages that: 1. with milling cutter to de-icing of power transmission lines, effective.2. walk on power transmission line with robot for overhauling, efficient is high.3. whole process need not manual operation, and security performance is good, and the deicing cost is low.

To combine embodiment that the present invention is further specified in conjunction with below Fig. 1～10.
The present invention relates to a kind of power transmission lines overhauling device; Particularly a kind of transmission line deicer; Comprise the sun gear 5 that is fastened on the power transmission line 20, be arranged on the retainer 7 that the outer and inwall of sun gear 5 is provided with for the shell 3 of " O " shape, along sun gear 5 outer wall circumference, cap 4, drive motors 12 and the decelerator that is connected with shell 3 tops and bottom; It is characterized in that: comprise 2～4 planet pins 2; These planet pin 2 one ends are connected with milling cutter 1, and the other end is connected with motor gear axle 10 through travelling gear and places in the chamber between sun gear 5 and the shell 3, and each planet pin 2 is arranged along the circumference of sun gear 5; One end of motor gear axle 10 cooperates with external gear 6 through travelling gear, described external gear 6, planet pin 2, sun gear 5, retainer 7 composition planetary gear mechanisms.
During work transmission line deicer is connected with the robot 19 of walking along transmission line through connecting plate 18, transmission line deicer can the power transmission line walking in the drive lower edge of the robot 19 of walking along transmission line.Sun gear 5, planetary gear wheel shaft 2, external gear 6, motor gear axle 10 form the planetary gear transmission; Sun gear 5 is axially static with respect to power transmission line 20 during work; Drive motors 12 drive motors gear shafts 10 rotate; And through motor gear axle 10, travelling gear, external gear 6, planet pin 2 power is conducted to milling cutter 1, make milling cutter 1 in rotation around sun gear 5 revolution.So milling cutter 1 can be removed the icing on the power transmission line.Should leave certain safety clearance between milling cutter 1 and the power transmission line 20, guarantee that milling cutter 1 can not damage power transmission line 20 in the ice detachment.Described robot 19 along the transmission line walking can select for use the patent No. to be: 200410061316.8, and name is called: a kind of robot that goes along aerial high-voltage power transmission line, the applying date is: the robot that is put down in writing in the invention of 2004.12.10 day.
And described external gear 6 left and right sides symmetric arrangement one external gear wheel roller 13; This external gear roller 13 is connected on the inwall of shell 3 through bearing; External gear 6 is taper with the contact-making surface of external gear roller 13, and the vertex of a cone of external gear roller 13 overlaps outside on the Gear axis.
At external gear 6 left and right sides symmetric arrangement one external gear wheel roller 13, external gear wheel 6 location are collected together its not meeting when rotating up and down.
Further technical scheme can be to have bonnet 8 to be arranged on an end of this transmission line deicer, and an end of this bonnet 8 is connected on the outer wall of sun gear 5, and the other end is connected with shell 3.
8 pairs of transmission line deicers of bonnet seal, and make it inner keep airtight relatively environment, can not should be sleety weather and influence its result of use.
And an end of retainer 7 is connected with shell through baffle plate 9; The other end cooperates with the inwall of bonnet 8 through retainer roller 15; Has groove on the contact-making surface of baffle plate 9 and retainer 7; Have ball 17 to be arranged in this groove, retainer roller 15 is taper with the contact-making surface of bonnet 8 inwalls, and the vertex of a cone of retainer roller 15 overlaps on sun gear 5 axis.
Retainer 7 is used for to planet pin provided thereon 2 location.
Retainer roller 15 is pyramidal structures with the contact-making surface on bonnet 8 tops; And the vertex of a cone that keeps two pyramidal structures overlaps and coincide point on the central shaft of sun gear 5; Retainer roller 15 is rolling friction with retainer 7 friction between retainer roller 15 and the bonnet 8 when sun gear 5 revolution; The coefficient of effectively reducing friction prolongs its useful life.
And on the planet pin 2 symmetric arrangement three pairs of bearings, inboard pair of bearings cooperates with external gear 6, the pair of bearings of centre cooperates with sun gear 5, the pair of bearings in the outside cooperates with retainer 7.
The ring gear of each bearing all cooperates with planet pin 2, and external toothing matches with each self-corresponding workpiece.
Further also can be described sun gear 5, retainer 7, shell 3, bonnet 8 by two parts up and down fasten technical scheme forms, and connect respectively through alignment pin.
Each main member is fastened by two parts up and down and forms, and the also easy access of breaking down is installed, convenient disassembly.
And drive motors 12 is connected on the shell 3 through cover plate 11.
The power of drive motors 12 is exported from motor gear axle 10 after slowing down.
