Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiment is a part of the embodiments of the present invention, rather than whole embodiments.Based on this hair
Embodiment in bright, those of ordinary skill in the art's every other reality obtained without making creative work
Example is applied, all should belong to the scope of protection of the invention.
Embodiment
A kind of livewire work side of wire fixture that the present invention is developed for super, UHV Overhead Transmission Line L-type string, it is high-strength
Degree fixture can shift conductor load, on the basis of meeting original V-type string, devise and meet multiple voltage grade, Duo Zhongfen
Wire form is split, the versatility lifting wire dress for needing to bear horizontal tension in asymmetric L-type suspension string is particularly met
It sets.
Specific 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 conducting wire
Side fixture, fixture are made of aluminum alloy materials.Fixture includes adjusting component 1, fixation kit and connector 3, adjusts component 1 and wraps
Two inverted triangle structure stands being fixedly connected are included, stake pad is equipped between two inverted triangle structure stands, adjusts component bottom edge both ends
It is respectively equipped with card slot 2, screw rod is installed in the card slot 2.Adjust component inverted triangle structure lower vertex by bolt with connect
Part 3 connects, and 3 lower end of connector is connected and fixed component.Fixation kit includes connecting plate 4, multiple clamping plates 5 and multiple fixed plates 6, is connected
Fishplate bar 4 is separately connected connector 3 and clamping plate 5, and clamping plate 5 is distributed in yoke plate two sides and the clamping plate of yoke plate two sides is bolted,
6 connecting cleat 5 of fixed plate.Each clamping plate is equipped with the different bolt hole of spacing.
The fixture is functionally divided into two parts up and down, and top main function is rotation and is promoted that lower part is fixed
Socket part point.Lower part is used to meet different yoke plate size requirements by designing the bolt hole of multiple and different distances, and for special
Asymmetric yoke plate is then realized by mobilizable clamping plate.And in order to improve component strength, it is used between ipsilateral two clamping plates
Positioning splint.Such design had both met the requirement for versatility, also in the case where meeting intensity requirement convenient for practical
Operation when construction.
The steering of fixture is mainly to be realized by cross reversing shaft, cross reversing shaft, that is, connector and connecting plate group
It closes, is directed in L-type suspension string and needs the case where bearing horizontal tension, come so that being promoted in the way of adjustment reversing shaft angle
Power is met the requirements, so that the promotion for solving asymmetric suspension string is difficult.
The top of fixture is then lift portion, it is contemplated that the form of construction work of livewire work, main lifting force are mentioned by lead screw
For the impulse stroke of lead screw is short, can satisfy the requirement of safe distance.Card slot is for disposing silk at the top design of device two
Bar has dispersed conducting wire using two screw rods also by the symmetrical card slot in both sides in addition to increasing component strength using triangular construction
Load, reduce the stress of single screw rod.And stake pad has 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 directlying adopt thread-lifting hook contact wire in the past, after Boards wall yoke plate, directly
Yoke plate is promoted to shift conducting wire load.The device is assembled by multi-sheets, can be installed to by way of lift in batches
