Description
Technical field
It is the utility model relates to a kind of aerial cable protective hardware that overhead power transmission line road uses, in particular to a kind of pre-
Hank knotting damper.
Background technique
It usually all needs to install and use damper on overhead power transmission line road, vibrates pine to avoid cable caused by wind etc.
It is de-.Damper used at present is that wire clamp is made to carry out compression suspension to aerial condutor by bolt mostly, and this form is when long
Between in use process the pressing force of bolt can decline, there is sliding of the wire clamp on conducting wire.In practice in order to meet wire clamp to leading
The grip of line can only select large diameter bolt, increase wire clamp to the pressure of conducting wire, also increase the damage to conducting wire, for a long time
Vibration friction can wear conducting wire, reduce route operation safety.Also, requirement of this form to installation quality compared with
Height is not easy to check whether qualification after installation, just can determine that after only running.
For above-mentioned phenomenon, 201821067 U of patent CN discloses a kind of pre-twisted wire damper, including wire clamp and fixation
The lateral steel strand wires of wire clamp lower part are connected to, the both ends of steel strand wires are respectively connected with tup, and the top of wire clamp is in hook solid, corresponding outstanding
It hangs on aerial condutor, matched multiply preformed armor rods are wrapped on wire clamp top and aerial condutor, constitute the connection of Wound-rotor type wire clamp
Fixed structure；The utility model compresses wire clamp using preformed armor rods winding and aerial condutor, preformed armor rods are big to the grip of aerial condutor,
It is connected firmly, wire clamp will not slide, and stress distribution is uniform, not damage wires, improve conducting wire vibration resistance, greatly prolong
The service life of conducting wire.Also, installation process is simple, is not necessarily to any specific purpose tool, and convenient for construction, behaviour is can be completed in a people
Make, is substantially shorter the construction time, the installation quality of wire clamp is easy to guarantee, can with the naked eye test, be not required to specially instruct
Practice；But there are still certain disadvantages for the pre-twisted wire damper of the structure：Cable is maked somebody a mere figurehead for a long time in the sky, will receive invading for sleet
Erosion increases the weight of cable, and the pre-twisted wire damper of the specification will be unable to the vibration of cable caused by effectively avoiding wind etc. and loosen,
Pre-twisted wire damper is needed to change, existing structure needs integral replacing, and it is inconvenient in turn result in replacement.
Therefore, it is anti-that a kind of preformed armor rods replaced conveniently and the vibration of cable caused by wind etc. can effectively be avoided to loosen are researched and developed
Vibration hammer is necessary.
Utility model content
Wind etc. can be avoided to cause the technical problem to be solved by the present invention is to provide a kind of replacement convenience and effectively
Cable vibrate the pre-twisted wire damper that loosens.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of pre-twisted wire damper, including wire clamp and
The lateral steel strand wires of wire clamp lower part are fixedly connected on, the both ends of steel strand wires are respectively connected with tup；The top of the wire clamp is in crotch
Shape, correspondence is suspended on aerial condutor, and matched multiply preformed armor rods are wrapped on wire clamp top and aerial condutor, constitutes coiling
Formula wire clamp is connected and fixed structure；Its innovative point is：The wire clamp adopts a split structure, and wire clamp top and wire clamp lower part are logical
Connected structure is crossed to be connected and fixed.
Further, the lower end on the wire clamp top is set as inverted U cavity configuration, and wire clamp lower part is set as cooperating with inverted U chamber
Convex shape structure；The upper end two sides of the convex shape structure are symmetrically provided with groove A, the cavity two sides of the inverted U cavity configuration
It is symmetrically arranged with the raised A with groove A cooperation；The bottom end two sides of the inverted U cavity configuration are symmetrically provided with groove B, the convex shape
The upper surface of the lower end two sides of structure is symmetrically arranged with the raised B with groove B cooperation.
Further, the top of the wire clamp is additionally provided with several protrusions, and each protrusion interval is evenly distributed, each stock preformed armor rods
The corresponding spacing convave trough across each protrusion.
The utility model has the advantage of：
（1）The utility model pre-twisted wire damper, wire clamp adopt a split structure, and wire clamp top passes through with wire clamp lower part
Connected structure is connected and fixed；Thus, cable is maked somebody a mere figurehead for a long time in the sky, and by the erosion of sleet, cable weight increases, and is needed to change
It is able to bear the pre-twisted wire damper of bigger weight specification, wire clamp lower part is only needed to change, i.e., is connect with lateral steel strand wires end
Tup, replacement is convenient, and no replacement is required, and pre-twisted wire damper is whole, and can effectively avoid the vibration pine of cable caused by wind etc.
It is de-；
（2）The utility model pre-twisted wire damper, wire clamp top and wire clamp lower part are above and below, left and right plug connection shape
Formula forms a stable triangular structure form, so that wire clamp top is connected firmly with wire clamp lower part.
Detailed description of the invention
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the structural schematic diagram of the utility model pre-twisted wire damper.
Specific embodiment
The following examples can make professional and technical personnel that the utility model be more fully understood, but therefore will not
The utility model is limited among the embodiment described range.
Embodiment
The present embodiment pre-twisted wire damper, as shown in Figure 1, including wire clamp 1 and the lateral steel for being fixedly connected on wire clamp lower part
Twisted wire 2, the both ends of steel strand wires 2 are respectively connected with tup 3；The top of wire clamp 1 is in hook solid, and correspondence is suspended on aerial condutor 4, and
Matched multiply preformed armor rods 5 are wrapped on 1 top of wire clamp and aerial condutor 4, are constituted Wound-rotor type wire clamp and are connected and fixed structure.
Wire clamp 1 adopts a split structure, and wire clamp top is connected and fixed with wire clamp lower part by connected structure；Specially line
The lower end on folder top is set as inverted U cavity configuration, and wire clamp lower part is set as the convex shape structure cooperated with inverted U chamber；Convex shape structure
Upper end two sides be symmetrically provided with groove A, the cavity two sides of inverted U cavity configuration are symmetrically arranged with the protrusion 11 with groove A cooperation；U
The bottom end two sides of cavity structure are symmetrically provided with groove B, and the upper surface of the lower end two sides of convex shape structure is symmetrically arranged with matches with groove B
The protrusion 12 of conjunction.
The top of the wire clamp 1 of the present embodiment is additionally provided with several protrusions 6, and each protrusion 6 is spaced evenly distributed, each stock
The spacing convave trough across each protrusion 6 is then corresponded to when preformed armor rods 5 are installed so that it is convenient to preformed armor rods 5 installation, while making preformed armor rods
The Winding pressure of 5 pairs of wire clamps 1 is more balanced.Aluminum-cladding stranded wire can be used in preformed armor rods 5, and intensity is high, and preformed armor rods 5 is outer
