Abstract
The invention discloses a combined damper. The combined damper comprises a pair of damper bodies. Each damper body comprises a central supporting base, wherein the bottom end of each central supporting base is connected with a damper weight through a steel wire rope, each damper weight is of a U shape, the upper end of each central supporting base is of a hook shape, one or more groove are formed in the outer surface of the upper end of each central supporting base, the hook-shaped portion of the upper end of each central supporting base is clamped on a cable needing to be fixed, strand twisted ropes penetrate through the grooves after being wrapped on the cables, and the side faces of the central supporting bases of the damper bodies are connected through a steel wire rope. The combined damper is simple in structure and convenient to implement; due to the fact that the grooves are formed in the outer surfaces of the central supporting bases, the twisted ropes for fixation can conveniently penetrate through the central supporting bases, and therefore on the one hand, the central supporting bases are fixed, and on the other hand, the outer surfaces of the cables cannot be damaged; after the damper bodies arranged on the two cables respectively are connected through the steel wire rope, the vibration prevention effect is further improved.
Description
technical field
The present invention relates to a kind of combined damper, belong to mechanical field.
Background technology
Stockbridge damper, establishes because wind-force shame plays vibration in order to reduce wire.High-tension overhead line bar position is higher, and span is larger, when wire is subject to wind-force, does the used time, can vibrate.During conductor vibration, the condition of work of wire hanging position is the most unfavorable.Due to repeatedly vibration, wire is because periodically bending can generation fatigue rupture.When overhead transmission line span is greater than 120 meters, generally adopt stockbridge damper vibrationproof.
Traditional stockbridge damper is clamped cable by fixture fixing, long in the time after, the drawback of this fixed form just displays, due to long-term swing, phase mutual friction between cable and fixture, can produce damage to cable outer surface.
Summary of the invention
For overcoming above-mentioned deficiency, the object of the invention is to provide and a kind ofly cable outer surface is not produced to damage, and firm effect good combined damper still.
A combined damper, comprises a pair of stockbridge damper;
Described stockbridge damper comprises central branches bearing, and described central branches bearing bottom connects hammer pouring weight by steel wire rope, and described hammer pouring weight is U-shaped shape;
Described central branches bearing upper end is hook solid, at upper end outer surface, more than one groove is set; The crotch place of central branches bearing upper end is fastened in required fixed cable, and hank knotting rope passes above-mentioned groove after wrapped cable;
Between described a pair of stockbridge damper, by steel wire rope, central branches bearing side is separately connected.
Further, described groove quantity is two, and described hank knotting rope quantity is two, respectively through groove.
Further, described groove quantity is identical with hank knotting rope quantity.
The present invention is simple in structure, and it is convenient to implement; By central branches supporting block outer surface is arranged to groove, convenient fixing with hank knotting rope passed central branches supporting block, on the one hand, central branches supporting block is further fixing, on the other hand, can not produce damage to cable outer surface.By after being separately positioned on two stockbridge dampers on cable and connecting by steel wire rope, further improve vibration-isolating effect.
Accompanying drawing explanation
Fig. 1 is vertical view of the present invention.
Fig. 2 is the Facad structure schematic diagram of stockbridge damper of the present invention.
Fig. 3 is the side structure schematic diagram of stockbridge damper of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
A combined damper, comprises a pair of stockbridge damper, is respectively stockbridge damper I 8, stockbridge damper II 9, and described stockbridge damper comprises central branches bearing 1, and described central branches bearing 1 bottom connects hammer pouring weight 3 by steel wire rope 2, and described hammer pouring weight is U-shaped shape; Described central branches bearing 1 upper end is hook solid, at upper end outer surface, more than one groove 4 is set; The crotch place 5 of central branches bearing 1 upper end is fastened in required fixed cable 6, and hank knotting rope 7 passes above-mentioned groove 4 after wrapped cable 6.
Described groove 4 quantity are two, and described hank knotting rope 7 quantity are two, and through groove, described groove 4 quantity are identical with hank knotting rope 7 quantity respectively.
The present invention fixes two stockbridge dampers separately by steel cable, make the vibration-isolating effect after combination better.
Although above the specific embodiment of the present invention has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present invention and change and revise; when its function producing does not exceed spiritual that specification contains yet, all should be within protection scope of the present invention.
