Abstract
The invention relates to a combined pre-twisted tension-resistant wire clamp, and relates to components of overhead line equipment. The combined pre-twisted tension-resistant wire clamp comprises a connecting device and two pre-twisted wires. The connecting device comprises a triangular connecting board which is in the shape of an isosceles triangle. The top corner end of the triangular connecting board is provided with a hanging hole, and two bottom corner ends are respectively hinged with a hanging board. The other ends of the hanging boards are connected with two connecting boards which are symmetrically arranged in a non-contacting manner. A rotatably roller is connected with the other end of each of the two connecting boards. Each roller is connected with a pre-twisted wire. A holding force of the combined pre-twisted tension-resistant wire clamp can reach up to more than 100%of a puling breaking force of the twisted wire. The combined pre-twisted tension-resistant wire clamp is difficult to cause damages, great in holding force and light in weight, and can reduce dynamic stress. The stress which is born by the twisted wire is uniformly distributed on a larger combining surface, and a phenomenon of stress concentration does not exist, thereby ensuring the normal service life of a system.
Description
Technical field
The present invention relates to the parts of overhead transmission line equipment, be specially a kind of combination pre-hinged strain clamp.
Background technology
Along with people's increasing rapidly electricity needs, but overhead insulating twisted wire all needs strain clamp to be connected with end at rotation angle position, and this just needs a large amount of strain clamps.Traditional strain clamp all adopts wedge structure, screw bolt-type structure or compression-type structure.Wedge strain resistance cable clamp is power of the splitting effect utilizing wedge type, and steel strand wire are locked in wire clamp.Due to the steel strand wire discontinuity be locked, this wire clamp easily damages steel strand wire thus causes its service life reduction.And bolt-type strain clamp is the frictional force utilizing the pressure at right angle of U-shaped screw and the wavy line groove of wire clamp to produce carrys out twisted pair wire and fix, but the frictional force obtained is less, the local stress at bolt-locking position is comparatively concentrated, and twisted wire easily gets loose, and fail safe is lower.Compression type strain clamp is continued and anchoring twisted wire by steel anchor, and then make aluminum pipe itself produce plastic deformation with pressure, thus make wire clamp and twisted wire in conjunction with as a whole, but need special equipment, complicated operation, installation quality is wayward.
Summary of the invention
The object of the invention is the shortcoming for overcoming prior art, providing a kind of structure simple, easy to use, and make a kind of pre-hinged strain clamp of twisted wire uniform stressed.
The technical scheme realizing above-mentioned purpose is: a kind of combination pre-hinged strain clamp, it is characterized in that: comprise jockey and two cover preformed armor rodses, described jockey comprises triangle yoke plate, triangle yoke plate be isosceles triangle, the drift angle end of triangle yoke plate is provided with hanging hole, two base angle ends of triangle yoke plate are hinged with link plate respectively, the other end of link plate is all connected with two pieces of symmetrically arranged connecting plates of not fitting, two pieces are bolted to connection between connecting plate and link plate, are all connected with rotating roller between the other end of two pieces of connecting plates; Each roller is connected to a set of preformed armor rods, and the end of two cover preformed armor rodses is nested on corresponding roller in doubled state respectively, two cover preformed armor rods remainders difference helically tubulose.
The invention has the advantages that: grip can reach more than 100% of twisted wire calculating pull-off force, and not easily cause damage, folder grip is large, lightweight, can reduce dynamic stress, the stress suffered by twisted wire is uniformly distributed at larger faying face, unstressed concentration phenomenon, thus the ordinary life of the system of guarantee.
Install simple between preformed armor rods and twisted wire, do not need any huge tool, a people can complete independently, and installation quality consistency is strong, simultaneously also conveniently checks; The twisted wire of various sectional dimension can be clamped simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention includes jockey 1 and two cover preformed armor rodses 2.
Jockey 1 comprises triangle yoke plate 3, triangle yoke plate 3 be isosceles triangle, the drift angle end of triangle yoke plate 3 is provided with hanging hole 4, two base angle ends of triangle yoke plate 3 are hinged with link plate 5 respectively, the other end of link plate 5 is all connected with two pieces of symmetrically arranged connecting plates 6 of not fitting, be bolted to connection between two pieces of connecting plates 6 and link plate 5, between the other end of two pieces of connecting plates 6, be all connected with rotating roller 7.
Each roller 7 is connected to a set of preformed armor rods 2, and the end of preformed armor rods 2 is that doubled state is nested on roller 7, preformed armor rods 2 remainder helically tubulose.
The present invention is when specifically using, first two preformed armor rodses 2 are each passed through corresponding roller 7, then by remaining preformed armor rods 2 uniform winding on twisted wire 8, the present invention is fixed in the structures such as pylon fixture by the hanging hole 4 then arranged by the drift angle end of triangle yoke plate 3.
