Description

A kind of coupling plate for transmission line lifting device
Technical field
The utility model belongs to electric power system field of overhead power transmission lines, is specifically related to a kind of coupling plate for transmission line lifting device.
Background technology
V-arrangement insulator string is the device that current ultra-high-tension power transmission line aerial condutor is commonly used.Insulator string is in series by multi-disc dish-type insulator, in running, due to reasons such as thunderbolt, pollution flashover, deteriorations, need change insulator string at any time; Simultaneously according to varying environment change, require different to the creepage distance of insulator string, also need to change insulator string.For not affecting the normal operation of circuit, needing workmen to carry out live line working on ultra-high-tension power transmission line, directly contacting high-voltage conducting wires by workman or carrying out changing the operation of insulator string by insulating tool.Conventional replacing options uses line lifter to carry out V-arrangement insulator string charged for replacement at present, and in work progress, after side insulator string departs from bowl head, yoke plate can be downward-sloping because of getting loose of one-sided pulling force, considerably increases difficulty of construction.
Utility model content
The utility model provides a kind of coupling plate for transmission line lifting device, this device can hold up from bottom by V-arrangement insulator string yoke plate entirety, realize the Integral lifting of yoke plate and wire, prevent yoke plate to both sides and the laterally inclined center of gravity deflection caused, solve the yoke plate tilt problem in charged for replacement V-arrangement insulator string work progress.
The utility model is realized by following scheme:
A kind of coupling plate for transmission line lifting device, comprises holding clamp, screw rod lifting device, insulation pull-rod, isosceles plate body, U-shaped supporting plate and cross-arm; Described holding clamp is arranged on cross-arm; Described insulation pull-rod is arranged on isosceles plate body, and described isosceles plate body is fixedly connected with U-shaped supporting plate; Described U-shaped supporting plate is arranged on V-arrangement insulator string yoke plate.
Preferably, described holding clamp is anchored on cross-arm by fixed groove.
Preferably, described U-shaped supporting plate is fixed by clamp nut and V-arrangement insulator string yoke plate.
Preferably, described isosceles plate body is provided with the first screwed hole group, and insulated tension pole is fixedly connected with by screwed hole group with isosceles plate body.
Preferably, described isosceles plate body is provided with the first sets of vias.
Preferably, described U-shaped supporting plate wooden partition top is provided with the second sets of vias, and bottom is provided with the second screwed hole group.
Preferably, described U-shaped supporting plate quantity is two.
The beneficial effects of the utility model are as follows:
When overhauling or change V-arrangement insulator string, by screw rod lifting device described in the utility model, yoke plate and wire integral lifting are promoted, after preventing one-sided insulator string from getting loose, yoke plate and wire are because of the one-sided stressed and difficulty of construction offseting and cause that drops, improve the convenience of operation, increase work efficiency and construction safety guarantee.The utility model is reasonable in design, and structure is simple, by the coupling of fixing hole group in use procedure, can adapt to difform V-arrangement insulator string yoke plate installation requirements, constructability personnel flexible operating.

Embodiment
As shown in Figure 1, this device comprises holding clamp 1, screw rod lifting device 2, insulation pull-rod 3, isosceles plate body 4, U-shaped supporting plate 5.
Described U-shaped supporting plate 5 quantity is 2.
Holding clamp 1 is anchored on cross-arm 9.Isosceles plate body 4 is connected by nut 6 and insulation pull-rod 3, and is connected by bolt group 7 and U-shaped supporting plate 5.U-shaped supporting plate 5 is fixed by clamp nut 8 and V-arrangement insulator string yoke plate 10.
As shown in Figure 2, holding clamp 1 is provided with cross-arm fixed groove 101, lifting device fixing hole 102.
As shown in Figure 3, isosceles plate body 4 drift angle place is provided with screwed hole group 401, and equilateral base angle is symmetrically arranged with sets of vias 402.
As shown in Figure 4 and Figure 5, U-shaped supporting plate 5 liang of wooden partition tops are symmetrically arranged with sets of vias 501, and bottom is symmetrically arranged with screwed hole group 502.
In the process changing V-arrangement insulator string, holding clamp 1 is first installed on the angle steel of cross-arm 9 by fixed groove 101 by operating personnel, and installs screw rod lifting device 2 at lifting device fixing hole 102 place; Insulated tension pole 3 and isosceles plate body 4 are connected by screwed hole group 401; By U-shaped supporting plate 5 by lower from be installed with V-arrangement insulator string yoke plate 10, according to the difference of the size of yoke plate, shape and thickness, select the different fixing holes of screwed hole group 502, be fixed by clamp nut 8.U-shaped supporting plate 5 can be exerted pressure in yoke plate both sides with being fixed of V-arrangement insulator string yoke plate 10 simultaneously, also can one-sidedly exert pressure.The top of U-shaped supporting plate 5 and isosceles plate body 4 are connected by bolt group 7.According to the difference of yoke plate shape, the coupling by sets of vias 402 and sets of vias 501 determines optimum fixation position.Insulation pull-rod 3 is connected with screw rod lifting device 2.After connecting above device, workmen lifts by crane screw rod lifting device 2, is lifted by crane by V-arrangement insulator string yoke plate 10, and insulator string lower end hanging point is relaxed, and implements the replacing operation of insulator string.
Above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, other amendments that those of ordinary skill in the art make the technical solution of the utility model or equivalently to replace, only otherwise depart from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of right of the present utility model.
