Abstract
The invention discloses a pre-formed armor connection wire clamp for a carrier cable. The pre-formed armor connection wire clamp comprises two spiral pre-formed wire sheets. The middle of the two spiral pre-formed wire sheets are wound to form a sealed circular tube. On the basis of enhancing anti-fatigue performance of the carrier cable, secondary protection of the carrier cable can be achieved: when strand breaking or wire breaking occurs to the carrier cable near a carrier cable seat, the pre-formed armor connection wire clamp can provide gripping force not lower than operation tension of the carrier cable and current-carrying capacity not lower than the current-carrying capacity of the carrier cable to the carrier cable, an overhead line system can normally operate when the carrier cable is damaged due to fatigue, and power failure and overhead line system collapse can be avoided. In addition, the pre-formed armor connection wire clamp which can be mounted with bare hands is simple and fast to operate.
Description
Technical field
The present invention relates to the railway contact line technical field, particularly relate to a kind of catenary with preformed armouring connecting clip.
Background technology
Along with the development of China's electrified railway, more and more higher to the performance requriements of contact nets in electrified railways parts.The effect of OCS Messenger Wire is by dropper contact wire to be hung up, and carries certain electric current and reduce impedance of traction electric network, reduces voltage loss and energy consumption.
The electric railway catenary is in operation affected by vibration,
Usually can cause catenary that disconnected strand or fully fracture occur at the Messenger Wire base place because of vibration, affect safe railway operation, increase inspection and maintenance cost.
Traditional catenary is at the fixing means at supporting base place, only is with putting into the catenary supporting base behind the liner parcel catenary, and is fastening and compress with gland through bolt.Because gland is narrower, when compressing catenary, thrust concentrates in the less scope in gland place, and the catenary under the gland bears very large stress.And contact net system is in vibrational state for a long time, and stress is concentrated, and very easily causes the endurance failure of catenary.
Summary of the invention
This
InventionProvide a kind of catenary to entreat with preformed armouring bond wire; there is catenary in the prior art because vibration fatigue and in the problem of Messenger Wire base place failure in order to solve, and can provides second protection to the catenary that because of vibration fatigue damage occurs at the Messenger Wire base place
,Can occur at the Messenger Wire base place to continue to guarantee the normal operation of contact system in the situation of the disconnected thigh of catenary or fracture, stop outage, the online story event of collapsing that contact system occurs because Messenger Wire base place catenary damages fully.
For reaching above-mentioned purpose, on the one hand, the invention provides a kind of catenary with preformed armouring connecting clip, described
PreformedThe armouring connecting clip comprises two screw-shaped preformed armor rods sheets, and the central authorities of two described preformed armor rods sheets are intertwined, and forms the sealing pipe.
Further, every described preformed armor rods sheet is comprised of some one metal wires, and every one metal wire all is prefabricated into spiral fashion lines consistent in shape and size.
Further, described metal filament adopts rhinemetal silk, high-strength copper silver alloy silk, high-strength copper Mg alloy wire.
Further, described

Further, part is twined in the central authorities of two described preformed armor rods sheets
Do twisting and process,Length is 300～500mm.
Further, the preformed armor rods sheet is to catenary
One-sidedHolding section length
BBe not less than 5 pitch.
Further, the metal filament sectional area summation of preformed armor rods sheet is not less than 1.5 times of catenary sectional area.
Further, the inboard of preformed armor rods sheet is bonded with conduction sand.
This
InventionBeneficial effect is as follows:
The preformed armouring connecting clip of the embodiment of the invention
CanGive full play to the preformed armor rods product to the unstressed centrostigma of wire, enhancing conductor rigidity, strengthen the characteristics of wire anti-fatigue performance.On this basis, when disconnected thigh or broken string occur near the catenary Messenger Wire base, this
Invention PreformedThe armouring connecting clip can provide the grip that is not less than the catenary running tension and be not less than the current-carrying intensity of catenary current capacity catenary, guarantees that circuit still can normally move
,Can not produce outage, collapse online story so, thereby reach the function of catenary being carried out second protection, improve the security and stability of contact net system
In addition, preformed armor rods structure, installation process need not the increase instrument,
PreformedThe armouring connecting clip is free-hand can finish installation, and fitting operation is simple and efficient.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment, to this
InventionBe further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain this
Invention, do not limit this
Invention
This
InventionEmbodiment relates to
PreformedThe armouring connecting clip is a kind of contact nets in electrified railways part, uses at OCS Messenger Wire seat place, strengthens the rigidity of Messenger Wire base place catenary, reduces the ess-strain of Messenger Wire base place catenary, effectively avoids the endurance failure of catenary; When catenary is damaged at the Messenger Wire base place, can play the interim effect that substitutes catenary, guarantee that contact net system can continue to move with security and stability, the online story event of can not cutting off the power supply, collapse.
As shown in Figure 3 originally
InventionEmbodiment relates to
PreformedThe armouring connecting clip comprises two screw-shaped preformed armor rods sheets, and the central authorities of two described preformed armor rods sheets are intertwined.
As shown in Figure 1, every preformed armor rods sheet is comprised of some one metal wires, and every one metal wire all is prefabricated into spiral fashion lines consistent in shape and size, and metal filament can adopt rhinemetal silk, high-strength copper silver alloy silk or high-strength copper Mg alloy wire.As shown in Figure 2, article two, the central wound portion of described preformed armor rods sheet is divided and is carried out twisting and process, the length of the central twisting processing section A of preformed armor rods sheet is 300-500mm, preformed armor rods sheet metal filament gross section is not less than 1.5 times of catenary cross section, side bonds conduction sand in the preformed armor rods sheet, the gripping length B one-sided to catenary is not less than 5 pitch.Preformed armouring connecting clip is wound in outside the catenary, and the internal diameter of preformed armouring connecting clip is less than the external diameter of catenary, and the internal diameter of preformed armouring connecting clip is 0.79～0.84 times of catenary external diameter.
