Road L-type suspension string livewire work side of wire fixture.
Background technology
Suspension string uses the form of V-type string more on super, UHV Overhead Transmission Line, in some towers for save into
This, in the straight line pole with small angle tower using the form of special L-type string.Insulator chain is directly exposed in air and undergo
Expose to the sun and rain, the Ageing of Insulators and damage in particular by ceramic material are more apparent, it is necessary to periodic inspection.And surpass, extra-high voltage
Overhead transmission line is to meet that power demands are not easy to interruption maintenance.High pressure is directly contacted by worker under circuit not power-off condition
Wire carries out operation by insulating tool, meanwhile, for a piece of Faulty insulator is taken out from an insulator string, it is necessary to make
With a kind of special mould clamp with tightening device, it is therefore an objective to make Faulty insulator and the insulator of both sides (totally three insulators) from
Tension (making insulator chain be in tensioned state because of some tons of hung wire of weight) is changed into relaxed state, in pine
To could be disengaged under relaxation state in steel cap and bulb corresponding to the bulb of Faulty insulator and steel cap from adjacent insulator, by its from
Take out and changed in suspension insulator.
Insulator chain is formed by multiple dish-type porcelain suspension insulators are stacked, and each dish-type porcelain suspension insulator passes through upper
Position insulator pin chapeau de fer tangles the next insulator the rim of a bowl and realizes flexible connection, and spring catch is arranged in the rim of a bowl, when spring catch is answered
It can be very good to fix the insulator during state of position, prevent upper insulator pin chapeau de fer from being slid from the next insulator the rim of a bowl；
When spring catch is pushed out the rim of a bowl, upper insulator pin chapeau de fer can be removed from the next insulator the rim of a bowl.In high-tension line band
, it is necessary to use insulation aid when being installed in the case of electricity, changing insulator, following wire is lifted, makes porcelain suspension insulator
Son is no longer influenced by wire tension, realizes safety work.At present, the maintenance of V-type string is changed dependent on the whole string of livewire work more, and L

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is the part of the embodiment of the present invention, rather than whole embodiments.Based on this hair
Embodiment in bright, the every other reality that those of ordinary skill in the art are obtained on the premise of creative work is not made
Example is applied, should all belong to the scope of protection of the invention.
Embodiment
A kind of livewire work side of wire fixture that the present invention develops for super, UHV Overhead Transmission Line L-type string, it is high-strength
Degree fixture can shift conductor load, on the basis of original V-type string is met, devise and meet multiple voltage grade, Duo Zhongfen
Wire form is split, the versatility lifting wire that particularly meets needs to bear horizontal tension in asymmetric L-type suspension string fills
Put.
Concrete structure：
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, Yi Zhongchao, UHV Overhead Transmission Line L-type suspension string livewire work wire
Side fixture, fixture are made of aluminum alloy materials.Fixture includes adjusting part 1, fixation kit and connector 3, and adjusting part 1 wraps
Two inverted triangle being fixedly connected structure stands are included, stake pad, adjusting part base both ends are provided between two inverted triangle structure stands
Neck 2 is respectively equipped with, screw mandrel is installed in described neck 2.The lower summit of adjusting part inverted triangle structure is by bolt with being connected
Part 3 connects, and the lower end of connector 3 is connected component.Fixation kit includes connecting plate 4, multiple clamping plates 5 and multiple fixed plates 6, even
Fishplate bar 4 connects connector 3 and clamping plate 5 respectively, and clamping plate 5 is distributed in yoke plate both sides and is bolted the clamping plate of yoke plate both sides,
The connecting cleat 5 of fixed plate 6.Each clamping plate is provided with the different bolt hole of spacing.
The fixture is functionally divided into two parts up and down, and for top main function to rotate and being lifted, bottom is fixed
Socket part point.Lower part is used for meeting different yoke plate size requirements by designing the bolt hole of multiple different distances, and for special
Asymmetric yoke plate is then realized by mobilizable clamping plate.And in order to improve component strength, used between homonymy two clamping plates
Positioning splint.Such design had both met the requirement for versatility, was also easy to reality in the case where meeting intensity requirement
Operation during construction.
The steering of fixture mainly realizes that cross reversing shaft is the group of connector and connecting plate by cross reversing shaft
Close, being directed in L-type suspension string needs to bear the situation of horizontal tension, causes lifting using the mode for adjusting reversing shaft angle
Power meets to require, so as to solve the lifting of asymmetric suspension string difficulty.
The top of fixture is then lift portion, it is contemplated that the form of construction work of livewire work, main lifting force are carried by leading screw
For the impulse stroke of leading screw is short, can meet the requirement of safe distance.Neck is used to dispose silk at the top design of device two
Bar, using triangular construction except increasing component strength, also by the symmetrical neck in both sides, wire is disperseed using two screw mandrels
Load, reduce the stress of single screw mandrel.And stake pad is have also been devised among triangle component, it is thick that different yoke plates can either be adapted to
The requirement of degree, while also component can be prevented to be deformed inward in stress, improve device intensity.
Fixture changes the hoisting way for directly using thread-lifting hook contact wire in the past, after Boards wall yoke plate, directly
Yoke plate is lifted to shift wire load.The device is assembled by multi-sheets, can be installed to by the form lifted in batches
Position, in the case where meeting intensity requirement, reduces the working strength of personnel on tower, and can meet in operation process for powered
The requirement of operation.
Operation principle：
As shown in figure 1, during work, fixation kit is fixedly connected with the yoke plate of L-type suspension string, adjusts turning for adjusting part
