Abstract
The utility model relates to a windproof side pull structure for a 220-kilovolt cat-head type tower. The windproof side pull structure comprises a diagonal cross arm, diagonal rings and diagonal wires, wherein the diagonal cross arm is fixed onto a steel frame beam through a fixing piece, and the diagonal rings are fixed onto steel frame vertical bars. Two ends of the diagonal cross arm are positioned on two sides of the steel frame beam respectively, a fixing joint is fixed at one end of the diagonal cross arm, the steel frame vertical bars are positioned on two sides of the steel frame beam, the two diagonal rings are sleeved on the steel frame vertical bars respectively, connecting rods are movably connected onto the diagonal rings and fixedly connected with connecting rings, and the diagonal wires are connected among the connecting rings and the fixing joint. The windproof side pull structure is better in wind-resistant effect, convenient and rapid to mount, portable and made of small materials, and labor intensity is relieved. When over-the-ground side pull of leads is eliminated, personal safety of equipotential operators is improved, line tripping power failure is avoided, and operation troubles caused by windproof stay wires are eliminated.
Description
Technical field
The utility model relates to the windproof layback structure of a kind of 220 kilovolts of cat head towers.
Background technology
At linear pattern cat head tower, common layback method is, dug the backguy hole and prefabricated cable quadrant, stay rod are installed in the outside, phase ground, iron tower limit in advance, by the equipotential mode of livewire work a composite insulator has been hung over the lead below then, its afterbody links to each other with stay rod with steel strand.The transmission line of electricity in wind district is through behind the layback over the ground, when high wind arrives, because the lead bottom is fixed by the wire rope of flexibility, it is limited in the little scope by the wind-force swing, thereby guaranteed that transmission line of electricity when suffering the high wind invasion and attack wind sudden strain of a muscle accident does not take place, operation shows through for many years circuit, and is very effective.
Along with increasing gradually of windproof retrofit work, the drawback of traditional windproof method of layback has over the ground also exposed one by one, taking over the ground, the mode of layback wastes time and energy very much, operating efficiency is also very low, main cause is when the soil alkalinity is big, soil is very hard, and hand excavation one Ji Laxiankeng often wants wasteful time half a day, and adopts the excavator excavation to have big potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of fixing cord, prevents the windproof layback structure of 220 kilovolts of cat head towers of windage yaw.
The purpose of this utility model is achieved in that 220 kilovolts of windproof layback structures of cat head tower are tiltedly to draw cross-arm by being fixed on the steelframe crossbeam, be fixed on the oblique draw ring on the steelframe montant, and lateral conductor is formed, tiltedly draw cross-arm to be fixed on the steelframe crossbeam by stator, tiltedly draw the cross-arm two ends to lay respectively at steelframe crossbeam both sides, the one end is fixed with stationary nodes, the steelframe montant is positioned at steelframe crossbeam both sides, two oblique draw rings are placed in respectively on the steelframe montant, active connection connecting rod on oblique draw ring, connecting rod is fixedlyed connected with connecting ring, is connected lateral conductor between connecting ring and stationary nodes.
Because carry out technique scheme, the utility model is better at actual wind resistance effect positive effect with respect to traditional method of layback over the ground, the tower material at each the tie point place of lengthening cross-arm that installs additional is not simultaneously found tangible deformation.The utility model is quick and easy for installation, and material is small and exquisite, light, has alleviated labour intensity.Eliminate lead over the ground during layback, improving the personal safety that equipotential is the industry personnel, avoiding line tripping power failure phenomenon simultaneously, and stopping the operation troubles that takes place because of windproof backguy.
Description of drawings: the technical solution of the utility model is provided by following drawings and Examples:
Fig. 1 is the structural representation of 220 kilovolts of windproof layback structures of cat head tower.
Legend: 1. oblique draw ring; 2. connecting rod; 3. connecting ring, 4. lateral conductor, 5. steelframe montant, 6. steelframe crossbeam, 7. stationary nodes is 8. tiltedly drawn cross-arm, 9. stator.
The specific embodiment:
The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
Embodiment: as shown in Figure 1, it is tiltedly to draw cross-arm 8 by being fixed on the steelframe crossbeam 6 for 220 kilovolts of windproof layback structures of cat head tower, be fixed on the oblique draw ring 1 on the steelframe montant 5, and lateral conductor 4 is formed.Tiltedly draw cross-arm 8 to be fixed on the steelframe crossbeam 6 by a stator 9, tiltedly draw cross-arm 8 two ends to lay respectively at steelframe crossbeam 6 both sides, the one end is fixed with stationary nodes 7, steelframe montant 5 is positioned at steelframe crossbeam 6 both sides, two oblique draw rings 1 are placed in respectively on the steelframe montant 5, active connection connecting rod 2 on oblique draw ring 1, connecting rod 2 is fixedlyed connected with connecting ring 3, is connected lateral conductor 4 between connecting ring 3 and stationary nodes 7.Tiltedly drawing cross-arm 8 lower surfaces installing insulator, insulator links to each other with lead.Stationary nodes 7 to the vertical line of steelframe crossbeam 6 distance greater than one meter.
Triangle slant-pull structure by tiltedly drawing cross-arm 8 and lateral conductor 4 to form makes insulator play stable pulling and supporting to lead, can effectively solve the lead windage yaw.
Above technical characterictic has constituted most preferred embodiment of the present utility model, and it has stronger compliance and best implementation result, can increase and decrease inessential technical characterictic according to actual needs, satisfies the needs of different situations.
