Abstract
The utility model relates to a suspension clamp, belonging to the technical field of the suspension clamp used for an overhead power transmission line. The suspension clamp comprises a wire clamp boat body, a pressing plate and a hanging plate, wherein the transverse center on the upper surface of the wire clamp boat body is provided with a wire slot; the pressing plate is also provided with a groove and is connected with the wire clamp boat body by a fastening piece; the wire slot is opposite to the groove; the edges and the corners of the wire clamp boat body are in smooth transition; the angle formed between the parts of the wire slot close to the two ends of the wire clamp boat body and the plane is within the range of 0-22 degrees; a port of the wire slot is inclined downwards; and the wire clamp boat body and the pressing plate are made of aluminium alloy. The suspension clamp prevents corona, and is light in weight, safe and reliable.
Description
Technical field
The utility model relates to a kind of overhead transmission line suspension clamp.
Background technology
Electric power conveying at present mainly is to rely on transmission line to finish, and twisted wire is installed in the direct-connected equipment suspension clamp that arrives commonly used on the iron tower, by suspension clamp twisted wire is tightened in certain position.Suspension clamp, in limited grip scope, lead wire and earth wire does not allow the generation of slip or break-off in wire clamp when normal operation of circuit or short circuit in requirement.
The Zhoushan of the whole nation first high tower, span maximum and the continent big overhead crossing engineering of networking mainly distributes across the sea.Crossover tower is the highest reaches 370m, the crossing span maximum reach 2756m, these two technical data be overhead crossing engineering.To use suspension clamp in this overhead crossing engineering.Suspension clamp originally can not satisfy the needs of actual use.
Summary of the invention
The purpose of this utility model provides a kind of anticorona, light weight, safe and reliable suspension clamp.
The utility model adopts following technical scheme:
The suspension clamp that this use is novel, comprise wire clamp hull, pressing plate and link plate, wire clamp hull upper surface transverse center has wire casing, fluted on the pressing plate, pressing plate links to each other with the wire clamp hull by securing member, and wire casing is relative with groove, wire clamp hull edge and angle are rounding off, wire casing is 0～22 ° near the part at wire clamp hull two ends with level angle, and the wire casing port is oblique down, and wire clamp body and pressing plate are the wire clamp body and the pressing plates of aluminium alloy system.
Described pressing plate number is more than or equal to 1.Described securing member is the bolt of stainless steel.
Compared with prior art, the utlity model has following advantage:
1, the material of wire clamp hull and pressing plate all adopts aluminium alloy, has alleviated the weight of product, has saved material, reduces the construction volume difficulty simultaneously, has saved cost.
2, the utlity model has obvious energy-saving effect.The wire clamp hull adopts non magnetic high-strength aluminum alloy material, and the design of the slyness of hull, and corona is no longer produced, and comparing traditional suspension clamp more has energy-saving effect.
3, the utlity model has superior decay resistance.Because wire clamp adopts aluminum alloy material, fastening bolt adopts stainless steel, makes product more corrosion-resistant, is fit to the use than heavily contaminated or high altitude localities.
4, wire casing is 0～22 degree near the part at wire clamp hull two ends and horizontal line angle, make that produce owing to gravity sag the concentrating with the stress wire casing port of cable eliminated or reduced, thereby the stress that reduces cable weares and teares.
5, the pressing plate number can be fixed in the wire clamp hull lead more than or equal to 1 preferably.

Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of catenary plate shown in Figure 1.
Fig. 3 is the left view of catenary plate shown in Figure 1.
Wherein 1, wire clamp hull; 2, pressing plate; 3, link plate; 4, wire casing; 5, groove; 6, bolt.
Embodiment
Suspension clamp of the present utility model, comprise wire clamp hull 1, pressing plate 2 and link plate 3, wire clamp hull 1 upper surface transverse center has wire casing 4, on the pressing plate fluted 5, pressing plate links to each other with wire clamp hull 1 by tight stainless steel bolt, wire casing 4 is relative with groove 5, cable is fastening, wire clamp hull 1 edge and bight are rounding off, wire casing is 0～22 degree near the part at wire clamp hull 1 two ends with the horizontal line angle, and wire casing 4 ports are oblique down, and wire clamp hull 1 and pressing plate 2 are wire clamp hull 1 and pressing plates 2 of aluminium alloy system.Link plate 3 is connected with wire clamp hull 1.
As shown in Figure 2, the pressing plate of present embodiment is 4.
The present embodiment suspension clamp is applicable to that it is that the preformed armor rods of 6.3mm protects lines that the JLB23-380 lead twines one deck external diameter outward, holds and puts forth effort to be not less than 65kN, and vertical breaking load is not less than 210kN.
