Abstract
The utility model discloses an anti-looseness damper for a transmission line, solving the problem that the prior damper is liable to damage a preformed wire armor rod on a wire, which leads to the looseness of a chuck and the easiness of the falling of the dampert. The technical proposal comprises two hammerheads which are respectively connected with the two ends of a wire rope, and the chuck sleeved on the wire rope. The chuck comprises a chuck seat board, a chuck cover and a wire hole. The chuck seat board is connected with the chuck cover by a fastener. The upper end of the chuck cover is articulated with the chuck seat board. An elastic cushion is arranged inside the wire hole. The chuck of the utility model has good chucking effect and is not easy to loose. The wire does not have to wind the preformed wire armor rod. The structure is simple and the installation is convenient.
Description
Technical field
The utility model relates to a kind of electric power protection gold utensil that is used for transmission line, a kind of specifically anti-loosening stockbridge damper.
Background technology
When lead is subjected to strong wind and blows, stronger vibration can take place, the effect of stockbridge damper in transmission line is the vibration that prevents and alleviate lead.In the prior art; and be that guardwire is avoided vibrating, wire clamp compression, friction, electric arc and other damage that all are external; usually be wound with preformed armor rods on the lead and protect lines; and the chuck of stockbridge damper is the rigidity structure; the preformed armor rods that is easy to damage on the lead in the long-term vibrationproof vibration damping process protects lines, thereby it is loosening to make its breaking strain that chuck is taken place, and reduces the clamping force to lead; influence vibration-isolating effect, even the problem that stockbridge damper comes off takes place.
On the other hand, because the chuck seat board of chuck only is connected by securing member such as bolt with the chuck lid, cause the clamping force of lead inhomogeneous, not only easily produce wearing and tearing to lead, and when taking place clamping force reduces, when chuck is loosening, lead is easy to be covered in the slit of end by chuck seat board and chuck, for transmission line brings serious potential safety hazard.
Summary of the invention
The purpose of this utility model is in order to solve the problems of the technologies described above, provide a kind of simple in structure, vibration-isolating effect good, the anti-loosening stockbridge damper big to the lead clamping force.
Technical scheme comprises two tups that are connected with the wirerope two ends respectively and is enclosed within chuck on the wirerope, described chuck comprises chuck seat board, chuck lid, wire guide, be connected by securing member between chuck seat board and the chuck lid, it is hinged with the chuck seat board that described chuck covers end, be provided with cushion in the wire guide that described chuck lid and chuck seat board form, described cushion is preferably selected elastomeric material for use, not only has elastic performance, also has certain anti-skidding effect.
Described chuck lid has two at least.
It is hinged with the chuck seat board that the utility model covers end by chuck, installs more convenient, again by securing member with lead fixed in the wire guide of chuck, increased the clamping force of chuck to lead, and by the cushion in the wire guide evenly conduction to lead.When the chuck clamping wire, because the existence of cushion, lead can directly not contact with the chuck of rigid material, damages distortion to cause chuck loosening thereby significantly reduce because of wearing and tearing repeatedly cause preformed armor rods to protect lines, thus the long-term variety of issue that uses the back stockbridge damper to come off and brought.Because the cushion effect that also has vibration damping, alleviate wire clamp compression, arc damage, therefore lead of the present utility model is installed need not to twine preformed armor rods and protect lines, reduced installation cost.The chuck lid is designed to two, can increases the clamping force of chuck greatly, further reduce the generation of above-mentioned safety problem lead.
Description of drawings
Fig. 1 is the utility model scheme of installation.
Fig. 2 is the cutaway view of chuck.
Wherein: 1-tup, 2-tup, 3-wirerope, 4-chuck, 4.1-chuck seat board, 4.2-chuck lid, 4.3-bolt, 4.4-wire guide, 4.5-rubber blanket, 4.6-bearing pin, 5-lead.
Embodiment
Below in conjunction with accompanying drawing the utility model is further explained explanation:
With reference to Fig. 1, Fig. 2, wirerope 3 two ends are connected with tup 2 with tup 1 respectively, chuck 4 includes chuck seat board 4.1, chuck lid 4.2, bolt 4.3, wire guide 4.4, rubber blanket 4.5 and bearing pin 4.6, described chuck seat board 4.1 lower ends are enclosed within on the wirerope 3, it is hinged by bearing pin 4.6 that chuck seat board 4.1 upper ends and two chucks side by side cover 4.2 upper ends, it is fixing to use bolt 4.3 that chuck lid 4.2 and chuck seat board 4.1 are tightened, and the wire guide 4.4 that described chuck lid 4.2 and chuck seat board 4.1 inner faces form also is provided with the rubber blanket 4.5 of annular.
During installation; open two chuck lids 4.2 simultaneously; lead 5 is inserted in the wire guide 4.4; close up chuck lid 4.2 then; respectively two chucks lid 4.2 and chuck seat board 4.1 are tightened with two bolts 4.3 fixing, rubber blanket 4.5 can with this clamping force evenly conduction not be worn for lead 5 and guardwire 5.Even when chuck 4 takes place slightly when loosening, its hinge arrangement can guarantee that also lead 5 can not deviate from easily from wire guide 4.4, avoid stockbridge damper to come off.
Claims (2)
1, a kind of anti-loosening stockbridge damper, comprise two tups that are connected with the wirerope two ends respectively and be enclosed within chuck on the wirerope, described chuck comprises chuck seat board, chuck lid and wire guide, be connected by securing member between described chuck seat board and the chuck lid, it is characterized in that: it is hinged with the chuck seat board that described chuck covers end, is provided with cushion in the described wire guide.
