Abstract

The utility model discloses a pre-twisted wire type vibration-proof hammer. The pre-twisted wire type vibration-proof hammer comprises a wire clamp, a soft suspension wire, a hammer head and at least one pre-twisted wire, wherein the soft suspension wire is fixedly connected with the lower part of the wire clamp; the hammer head is fixed at the two ends of the soft suspension wire; the pre-twisted wire is wound on the upper part of the wire clamp and an overhead cable; and an anti-skid structure for preventing the wire clamp from moving on the overhead cable is arranged on each pre-twisted wire. Compared with the traditional similar vibration-proof hammer, the pre-twisted wire type vibration-proof hammer has a reasonable structure and can effectively prevent the wire clamp from moving on the overhead cable so as not to influence the using effect of the vibration-proof hammer.

Description

The pre reeled silk type stockbridge damper

Technical field

The utility model belongs to overhead transmission line protection gold utensil structure-design technique field, is specifically related to a kind of formula stockbridge damper of pre-paying.

Background technology

The phenomenon of ubiquity aeolian vibration in the overhead transmission line, the long-term vibration aerial cable that is in ultra scope may make broken cable with the friction of tower bar junction.In order to prevent the generation of this type of phenomenon, comparatively general way is that the vibrationproof gold utensil is installed on aerial cable at present, to suppress, to weaken the cable vibration that gentle breeze causes, makes it to drop within the permission limit.Stockbridge damper in the market is divided into bolt type and pre reeled silk type, and comparatively speaking both pre-pay a formula and have more advantage.The pre reeled silk type stockbridge damper mainly comprises wire clamp, be fixedly connected on the soft messenger wire of said wire clamp bottom, be fixed on the tup and the preformed armor rods at soft messenger wire two ends; Said preformed armor rods is wrapped on the top and aerial cable of said wire clamp; Adopt the stockbridge damper vibration-isolating effect of this structure more remarkable; Has good result of use; Yet the used preformed armor rods major part of existing pre reeled silk type stockbridge damper is to adopt ganoid aluminum cald steel wire, when on cable, moving after installing, though the position of preformed armor rods on cable can not change; But the stockbridge damper wire clamp have can be movable scope, general range the installation site ± 12mm.This movable scope has also had influence on stockbridge damper vibration-isolating effect on cable to a certain extent.Therefore, but the structure of existing stockbridge damper also has improvements.

Summary of the invention

To the deficiency that prior art exists, it is a kind of rational in infrastructure and vibration-isolating effect is good pre-pays a formula stockbridge damper that the utility model provides, and than traditional similar stockbridge damper, the vibration-isolating effect of the stockbridge damper in the utility model is more remarkable.

The technical scheme that realizes the utility model purpose is: a kind of pre reeled silk type stockbridge damper comprises wire clamp, is fixedly connected on the soft messenger wire of said wire clamp bottom, the tup that is fixed on soft messenger wire two ends and at least one preformed armor rods; Said preformed armor rods is wrapped on the top and aerial cable of said wire clamp; Each said preformed armor rods is provided with the anti-skid structure that prevents the activity on aerial cable of said wire clamp.

In the technique scheme, said anti-skid structure is on the outer surface of each said preformed armor rods, to be covered with the grains of sand or iron pin.

In the technique scheme, said soft messenger wire is steel strand wire, elastic steel strip or spring.

In the technique scheme, said preformed armor rods is an aluminium Baogang preformed armor rods.

In the technique scheme, the quantity of said preformed armor rods is three, and the length of every preformed armor rods is between 650mm to 700mm.

In the technique scheme, the top of said wire clamp is hook solid, forms several convexities on the top of wire clamp, forms groove between the adjacent protrusion, and each said preformed armor rods passes from said groove.

The good effect that the utlity model has is:

Each said preformed armor rods of preformed armor rods stockbridge damper in the utility model is provided with the anti-skid structure that prevents the activity on aerial cable of said wire clamp; Since the setting of anti-skid structure can effectively avoid stockbridge damper in running because wire clamp movable on aerial cable and then have influence on the result of use of stockbridge damper; Than traditional pre reeled silk type stockbridge damper; The structure of the stockbridge damper of said structure is more reasonable, and vibration-isolating effect is better.

Embodiment

(embodiment 1)

Fig. 1 and Fig. 2 have shown a kind of embodiment of the utility model.Wherein, Fig. 1 pre-pays a kind of structural representation of a formula stockbridge damper in user mode for the utility model; Fig. 2 is that Fig. 1 is along A-A line side cross sectional view;

A kind of pre reeled silk type stockbridge damper, as shown in Figure 1, comprise wire clamp 1, be fixedly connected on the soft messenger wire 2 of said wire clamp 1 bottom, the tup 3 that is fixed on soft messenger wire 2 two ends and at least one preformed armor rods 4; Said preformed armor rods 4 is wrapped on the top and aerial cable 7 of said wire clamp 1; Each said preformed armor rods 4 is provided with the anti-skid structure that prevents the activity on aerial cable 7 of said wire clamp 1; Said anti-skid structure is on the outer surface of each said preformed armor rods 4, to be covered with the grains of sand or iron pin; The grains of sand such as quartz sand etc.; Because anti-skid structure, has fully limited the scope of wire clamp 1 activity on aerial cable 7 to the effect of wire clamp, and then makes the pre reeled silk type stockbridge damper have good vibration-isolating effect.Said soft messenger wire 2 can be steel strand wire, elastic steel strip or spring, and said preformed armor rods 4 is an aluminium Baogang preformed armor rods.

In the present embodiment, the quantity of said preformed armor rods 4 is three, and the length of every preformed armor rods 4 is between 650mm to 700mm.The top of said wire clamp 1 is hook solid; Form several convexities 5 on the top of wire clamp 1; Form groove 6 between the adjacent protrusion, each said preformed armor rods 4 passes from each said groove 6, can be referring to Fig. 2; Be convenient to the installation of preformed armor rods 4 through convexity 5 is set, wire clamp 1 is more reliable with being connected of preformed armor rods 4.

Each said preformed armor rods of preformed armor rods stockbridge damper in the present embodiment is provided with the anti-skid structure that prevents the activity on aerial cable of said wire clamp; Since the setting of anti-skid structure can effectively avoid stockbridge damper in running because wire clamp movable on aerial cable and then have influence on the result of use of stockbridge damper; Than traditional pre reeled silk type stockbridge damper; The structure of the stockbridge damper of said structure is more reasonable, and vibration-isolating effect is better.

Obviously, the foregoing description of the utility model only be for explain clearly that the utility model does for example, and be not to be qualification to the execution mode of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all execution modes.And conspicuous variation that these connotations that belong to the utility model are extended out or change still belong to the protection range of the utility model.
