The self-adjusting tensile force deicing suspension clamp is additionally provided with a cover on an existing suspension clamp, which can effectively prevent icy snow or icy rain from entering the clamp boat body and an eccentric chuck block, thereby, the clamp boat body and the eccentric chuck block can not be frozen, the eccentric chuck block still can act freely even in cold and wet winter, thereby, line conductors can be twitched, the tensile force self-adjustment is realized, the tensile force balance of the line conductors on two sides of a straight line tower is guaranteed, and the possibility of tower collapse of the straight line tower due to tensile force imbalance on two sides after the line conductors are covered with ice is reduced. Furthermore, since the cover can swing forwards and backwards, thereby, ice can not be accumulated on the clamp boat body and the cover easily, which plays good deicing effect.
Description
Technical field
The utility model relates to the suspension clamp that a kind of circuit of transmitting electricity is used, and relates in particular to the anti-icing suspension clamp of a kind of self-regulated tension force.
Background technology
It mainly is to rely on the transmission of electricity circuit to finish that present electric power is carried, and twisted wire is installed in that direct-connected equipment mainly is suspension clamp, strain clamp etc. on the iron tower, and twisted wire is guided and supported in the effect of suspension clamp with exactlying on tangent tower, go here and there through dangling to link to each other with the cross-arm of shaft tower.
Used suspension clamp is made up of wire clamp hull, connecting bolt, U bolt, tension disc, pin etc. usually at present, and such suspension clamp can only play the effect of guiding and supporting twisted wire, can not self-regulated tension force.Also have this class suspension clamp under southern china freezing disaster weather in 2008, expose can not be anti-icing problem, accumulated ice appears easily.
The utility model content
Technical problem to be solved in the utility model provides a kind of energy self adjustment of tonicity and has the anti-icing suspension clamp of self-regulated tension force of good anti-icing effect.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
The anti-icing suspension clamp of self-regulated tension force, comprise the wire clamp hull, it is characterized in that, also comprise a dual U-shaped connector and a lid, the following U-shaped connector of described dual U-shaped connector flexibly connects by bearing pin and described wire clamp hull, described lid be installed on the described dual U-shaped connector and cover cap on described wire clamp hull.
The cross section of described lid becomes the U type and is made by elastomeric material.
In order to make the utility model under normal operation, lead do not presented to hold put forth effort, under unbalanced state, lead can be twitched and the utility model is limited grip, the utility model also comprises an eccentric fixture block, described eccentric fixture block is a fan-shaped fixture block, backs down one at the fan of described fan-shaped fixture block and holds the hole that described bearing pin passes, and described bearing pin passes this hole described eccentric fixture block off-centre is installed in the described main body; The segmental arc of described eccentric fixture block is provided with a draw-in groove, and this draw-in groove is held lead with described wire clamp hull.
In order to improve self-damping vibration-damping function of the present utility model, in described wire clamp hull and the rubber buffer that is provided with U type structure in the segmental arc of described eccentric fixture block.Adopting rubber buffer one is to improve self-damping vibration-damping function of the present utility model, the 2nd, prevent the wearing and tearing of lead.
Described body rim portion and bight are slick and sly streamlined.
The side plate of described lid is triangular in shape, and the two ends of lid are provided with bead, and the purpose that bead is set is to prevent that ice and snow or rainwater from flowing in the main body or on the lead, to prevent main body, eccentric fixture block accumulated ice along lid.
Be provided with the groove that the appearance lead passes in bead bottom, the two ends of described lid, this groove is pressed on the lead, when lead is twitched, the accumulated ice of lead can clash into lid, because lid adopts elastomeric material, to make as rubber, ice impinges upon soft covering and can break, strip down and fall down from lead, thereby embody anti-icing purpose of the present utility model more.
The edge part of described lid and bight are slick and sly streamlined.The utility model has one at caping and holds the hole that the dual U-shaped connector passes, be provided with some spreading seams at the edge in described hole, when the dual U-shaped connector passed hole on the caping, these spreadings seams can spreadings, make the U-shaped connector of dual U-shaped connector upper end pass this hole smoothly.After the U-shaped connector of dual U-shaped connector upper end passed this hole smoothly, these spreading seams can restore, and wrap on the joint pin of dual U-shaped connector, by an anchor ear described lid and dual U-shaped connector are fastenedly connected again.
After the utility model uses lid, can prevent effectively that ice and snow or ice rain water from entering into main body, eccentric fixture block, therefore main body, eccentric fixture block can not be frozen in, even in cold, moist winter, eccentric fixture block also can move freely, thereby lead can be twitched, realized the self-regulated of tension force, guaranteed the balance of tangent tower both sides wire tensions, reduced tangent tower because behind the wire icing, the both sides tension imbalance causes down the possibility of tower.Because therefore the swing of lid energy is not easy accumulated ice at the wire clamp hull with covering, played good anti-icing effect in addition.
The utility model deft design, result of use is good, has improved the fail safe and the reliability of power cable line, can satisfy the grip requirement of circuit operation.
Description of drawings
Fig. 1 is the structural representation of the anti-icing suspension clamp of the utility model self-regulated tension force.
Fig. 2 is the exploded perspective view of Fig. 1.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
Referring to Fig. 1 and Fig. 2, the anti-icing suspension clamp of self-regulated tension force comprises wire clamp hull 100, a dual U-shaped connector 200, one eccentric fixture block 600 become the U type with a cross section lid 300.
Be provided with the groove 310 that the appearance lead passes in the bead bottom, two ends of lid 300, this groove 310 is pressed on the lead, when lead is twitched, the accumulated ice of lead can clash into and cover 300, because lid 300 adopts elastomeric material, makes as rubber, ice impinges upon on the soft lid 300 and can break, strip down and fall down from lead, thereby embody anti-icing purpose of the present utility model.
