Abstract

The utility model relates to a grading and shielding ring with adjustable, it includes two supports, a grading and shielding ring, a connecting seat and an adjustable support arm, two supports are approximate V -arrangement structure, the equal and grading and shielding ring fixed connection in every support both ends, the V -arrangement structure bottom of two supports all with connecting seat fixed connection, connecting seat and adjustable support arm swing joint. The connecting seat is provided with two bolt holes through welding mode and grading and shielding ring and two support fixed connection on the connecting seat. Adjustable support arm horizontal direction is provided with two regulation holes side by side, and two bolts pass two regulation holes respectively with adjustable support arm and connecting seat swing joint, and the vertical direction of adjustable support arm is provided with a plurality of regulation holes side by side. The utility model provides a current grading and shielding ring can't adjust for fixed mode, with the problem of draining jumper looks likely to suffer from collision.

Description

One is adjustable all presses shading ring
Technical field
This utility model relates to all pressures shading ring in a kind of transmission line of electricity, especially with regard to a kind of use in UHV transmission line anchor support adjustable all press shading ring.
Background technology
At present, the anchor support of transmission line of electricity carries the critical functions such as corner, lead wire and earth wire tension force, isolation accident, alignment, adjustment tower height, and anchor support is great with work transmission line security relationship.1000kV UHV transmission line engineering requires height because of its width of corridor, and social influence and environmental effect are relatively big, and therefore buckling factor strain insulator length bigger, average is shorter.The average strain section length of built southeast Shanxi~Nanyang~mono-time extra high voltage line of Jingmen 1000kV and Huainan~Zhe Bei~Shanghai 1000kV double back extra high voltage line is about 3.4km, needs the anchor support quantity used many;Anchor support is the tangent tower of same height because the quantity and specification bearing the material such as lead wire and earth wire tension force and angle load, tower material, basic and attached insulator, gold utensil, wire jumper is all significantly larger than;The wire jumper of extra-high voltage project and jumper string not only cost is high, and is construction, the weak link run.Extra high voltage line wire jumper drainage thread has the features such as line footpath is thick, rigidity is big, division number is many, wire jumper distance, difficulty of construction are big, is the difficult point of Poling Construction all the time.Practice of construction and the ruuning situation of engineering is sent according to 1000kV UHVAC demonstration project and Wan electricity Dong, big corner and single loop anchor support drainage thread in time jumping often occur all to press with strain insulator-string shading ring to collide situation about interfering, cause drainage thread and the abrasion of relevant gold utensil, deformation, cause drainage thread premature abrasion, disconnected stock or broken string, bigger hidden danger is brought to UHV transmission line safe operation, although taking measures such as having installed TJ2 type jumper wire spacing rod and space-adjusting wire clamp additional, serve some protective effects, but owing to line hardware is chronically at the natural environment that field is severe, especially under large wind effect, still it is difficult to reach very good technique effect.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of adjustable all presses shading ring, and which solving existing all pressures shading ring is that fixed form cannot be carried out regulation, the problem easily collided with drain wire jumper.
For achieving the above object, this utility model takes techniques below scheme: a kind of adjustable all presses shading ring, it is characterised in that it includes two stands, one all presses the adjustable support arm of shading ring, a connecting seat and;Support described in two is approximation v-shaped structure, and each described support two ends are all fixing with described all pressures shading ring to be connected, and the v-shaped structure bottom of support described in two is all connected the fixing connection of seat with described, and described connection seat is flexibly connected with described adjustable support arm.
Preferably, described connection seat is connected by welding manner is fixing with described all pressure shading rings and described two stands, and described connection seat is provided with two bolts hole.
Preferably, described adjustable support arm horizontal direction has been arranged side by side two adjustment holes, and two bolts are each passed through two described adjustment holes and are flexibly connected with the described seat that is connected by described adjustable support arm;Described adjustable support arm vertical direction is provided with some described adjustment holes side by side.
This utility model is owing to taking above technical scheme, it has the advantage that 1, this utility model uses and adjustable all presses shading ring, by regulation all pressure adjustable support arms of shading ring, change all pressure shading ring distances away from strain insulator-string split conductor division circle center, avoid drain wire jumper, reach the purpose not collided with shading ring after wire jumper is installed.2, this utility model employing is adjustable all presses shading ring, and simple in construction is suitable for, regulation dependable performance, large-scale application convenient for installation and maintenance, suitable.

Detailed description of the invention
With embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
As shown in FIG. 1 to 3, this utility model offer one is adjustable all presses shading ring, and it includes that two stands 1, all presses shading ring 2, a connecting seat 3 and an adjustable support arm 4.Two stands 1 is approximation v-shaped structure, and each support 1 two ends are all connected with all pressure shading ring 2 is fixing, by two stands 1 fixing all pressures shading ring 2.The v-shaped structure bottom of two stands 1 all be connected that seat 3 is fixing to be connected, connect seat 3 to be flexibly connected with adjustable support arm 4, seat 3 is connected in the position of adjustable support arm 4 by regulation, and then the position of regulation all pressure shading rings 2, make all to press shading ring 2 away from drain wire jumper, it is to avoid drain wire jumper and the collision all pressing shading ring 2.
In above-described embodiment, two stands 1 by welding manner respectively with all press shading ring 2 and be connected the fixing connection of seat 3, connection seat 3 is provided with two bolts hole, is used for being fixed on adjustable support arm 4.
In the various embodiments described above, as shown in Figure 4, adjustable support arm 4 horizontal direction has been arranged side by side two adjustment holes 5, and two bolts are each passed through two adjustment holes 5 and are flexibly connected with being connected seat 3 by adjustable support arm 4.Adjustable support arm 4 vertical direction is provided with some adjustment holes 5 side by side, connects seat 3 and is flexibly connected by the adjustment hole 5 with diverse location, regulates the position all pressing shading ring 2.
The various embodiments described above are merely to illustrate this utility model; the structure of each parts, size, position is set and shape all can be varied from; on the basis of technical solutions of the utility model; all improvement carried out individual part according to this utility model principle and equivalents, the most should not get rid of outside protection domain of the present utility model.
