Description
Technical field
The utility model belongs to a kind of electric armour clamp, particularly a kind of preformed armor rods hippocampus stockbridge damper using in electric power line pole tower both sides.
Background technology
Can there is multiple disaster accident because of the effect of natural conditions in overhead transmission line, threaten the safe and stable operation of circuit in the process of operation, overhead transmission line wave be exactly wherein endanger larger a kind of.Waving of overhead transmission line is a kind of air force wild effect, is a kind of low frequency of causing under the External Force Actings such as wind-force of transmission line wire, the chattering of large amplitude, is also that dynamic excitation makes the constantly result of accumulation of energy.Wave the tension variation that has caused transmission pressure excessive, can produce many-sided harm to transmission line, become comparison distinct issues of power industry.For what eliminate transmission line, wave people installation interval rod or stockbridge damper between transmission line, so that the energy that wire is swung consumes.Between the existing most of stockbridge dampers of China and transmission pressure, be all with bolts, therefore, during installation, need special-purpose wrench, if misoperation, too small or the excessive situation of moment of torsion will occur, and moment of torsion is too small, and the grip between stockbridge damper and transmission pressure does not just reach requirement.Moment of torsion is excessive, can cause the damage of transmission pressure or bolt.And, even if the grip between stockbridge damper and wire has reached the requirement of regulation when mounted, but the vibration along with transmission pressure and stockbridge damper in circuit running, stress between transmission pressure and bolt can be loose gradually, grip between transmission pressure and stockbridge damper also can reduce gradually, also there will be the loosening phenomenon of stockbridge damper, cause stockbridge damper to depart from initial installation site, this phenomenon often occurs in the line.
In order to address the above problem, people have developed Pretwisted installation type shockproof hammer, as shown in Figure 4, this Pretwisted installation type shockproof hammer mainly consists of preformed armor rods, wire clamp, messenger wire and hammer body, and the cross section of wire clamp is Y-shaped, top is with the through hole of V-arrangement, preformed armor rods, through V-arrangement through hole, then, is wrapped on transmission pressure, messenger wire is fixed in the hole of wire clamp bottom, and hammer body is fixed on the two ends of messenger wire.Though this Pretwisted installation type shockproof hammer has been eliminated the shortcoming of above-mentioned bolt fastening stockbridge damper, but inconvenience is installed, operation effort, because the below of the V-arrangement opening on wire clamp top in transmission pressure, during installation, play wire clamp, messenger wire and hammer body with a hand rest, another hand is wound around preformed armor rods, under the condition of work high above the ground, the difficulty of installation is larger.And, install rear stockbridge damper and tend to offset from perpendicular, that is to say that hammer body tends to not under transmission pressure, can be amesiality, then, must adjust mounted stockbridge damper, be torqued into transmission pressure under, not only time-consuming, effort, also can cause certain infringement to transmission pressure.In addition, conventionally adopt the mode of welding or crimping to be fixed together between messenger wire and hammer body, these two kinds of connected modes all exist certain problem.If adopt the mode of welding, because messenger wire is steel strand wire, when welding, messenger wire is heated and can blows, and affects its intensity.In addition, during welding, also can cause the destruction of messenger wire surface zinc layer, in use get rusty easily, reduce the useful life of stockbridge damper.If adopt the mode of crimping, first will be on messenger wire sleeve of crimping, then, then hammer body is crimped on sleeve, and, hammer body crimping messenger wire to connect mouth very short, its length is no more than 10 millimeters, during crimping messenger wire, its crimping fixing point is close to the bottom of hammer body, easily make the root that connects mouth occur crackle, in the process of using, have the phenomenon that hammer body comes off in wire running.Some crackles are hidden in hammer body inside, and after crimping, naked eyes be can't see at all, and this can cause very serious hidden danger to the safe operation of transmission line.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of assemble simple, be connected firmly, be convenient to install, without the preformed armor rods hippocampus stockbridge damper of potential safety hazard.
The utility model comprises preformed armor rods, wire clamp, messenger wire and hammer body, messenger wire is fixed in the hole of wire clamp bottom, hammer body has two, be separately fixed at the two ends of messenger wire, its special character is, the cross section of wire clamp is hook-shaped, and the through hole of an arc is arranged at its top, sticks with glue agent and bond together between messenger wire and hammer body.
The utility model has the advantage of:
1, between messenger wire and hammer body, sticking with glue agent bonds together, the problems such as the messenger wire of welding manner generation is blown and messenger wire surface zinc layer is destroyed have been avoided, also stopped the injury of crimping mode to hammer body root, avoid having occurred on hammer body crackle, greatly extended the useful life of stockbridge damper, guaranteed the operation that transmission line is safe and reliable, and, assembling is simple, is connected firmly, and has also improved production efficiency.
2, the cross section of wire clamp is hook-shaped, while installing on transmission line, without hand, go again holding in the palm it, wire clamp is directly hooked on transmission line and just can be installed, greatly reduce operating personnel's working strength and the difficulty of installation, and after installing, stockbridge damper can offset from perpendicular, does not need to adjust yet again.
