Abstract
The utility model relates to a novel termination anchoring wire clip for a carrier cable. The termination anchoring wire clip consists of a wire clip body (1), a thread wedge jacket (2) and a tapered wedge (3), wherein the upper part of the wire clip body (1) is a U-shaped double-lug, and the lower part thereof is a thread sleeve; the tapered wedge (3) is inserted in the inner taper hole of the thread wedge jacket (2); the inner end of the thread wedge jacket (2) is screwed in the thread sleeve at the lower part of the wire clip body (1) by external screw thread on the outer wall of the thread wedge jacket (2); a connecting hole (6) is arranged on the U-shaped double-lug at the upper part of the wire clip body (1); and a pin (4) is inserted into the connecting hole (6). The termination anchoring wire clip has simple structure and convenient installation, debugging and maintenance, and adopts the outer layer unidirectional active clipping mode, thereby improving the safety and reliability of anchorage installation and disjunction connection, therefore, the safety property of the whole electrical contact net is more superior.
Description
Technical field
The utility model relates to a kind of novel bearing rope end anchorage wire clip, belongs to contact nets in electrified railways Parts manufacturing technology field.
Background technology
The catenary of contact nets in electrified railways in use needs segmentation to cast anchor inevitably or disjunction connects, termination fitting for catenary is exactly to be used for the strength member that online bitter end head connects with other parts, and how the performance of terminal anchoring clamp directly has influence on the safety of whole electrified contacting nets.With the immediate prior art of the utility model be cast steel (or cast copper) ears wedge clamp, awl tube (ears) bolt type terminal anchoring clamp and template ears taper sleeve type terminal anchoring clamp.Simple in structure, easily manufactured, the simple installation of cast steel (or cast copper) ears wedge clamp, but clue must bend and pack tightly chock during owing to installation, and the copper alloy clue hardness that generally adopts at present is higher, the more large and small radius bending of diameter difficulty, and has problems such as bending back broken lot, Internal and external cycle stress be inconsistent.Awl tube (ears) bolt type terminal anchoring clamp complex structure, need the wire stripping layering when installing, complex operation, and operation difficulty relatively when using the high strength clue; Template ears taper sleeve type terminal anchoring clamp adopts passive clamping mechanism, has safety hazard.
Summary of the invention
The technical matters that the utility model solves: design a kind of novel bearing rope end anchorage wire clip, simple in structure, installation, debugging and easy to maintenance, adopt outer unidirectional active clamping mode, having improved the safety and the reliability of cast anchor installation and disjunction connection, having made the safety performance of whole electrified contacting nets more superior.
Technical solution of the present utility model: a kind of novel bearing rope end anchorage wire clip, constitute by wire clip body (1), screw thread cover of wedge (2) and taper chock (3), the top of wire clip body (1) is " U " type ears, the bottom is a screw thread bush, taper chock (3) is inserted in the internal taper hole on the screw thread cover of wedge (2), the inner of screw thread cover of wedge (2) is contained in the screw thread bush of wire clip body (1) bottom by the external thread rotary on its outer wall, be shaped on connecting bore (6) on " U " type ears on wire clip body (1) top, be fitted with pin (4) on the connecting bore (6).
The outer end of described screw thread cover of wedge (2) is shaped on outer six side's boss (7).
The tapering of described chock (3) is greater than the tapering of screw thread cover of wedge (2) internal taper hole.
Described wire clip body (1), screw thread cover of wedge (2) adopt behind the copper alloy forging forming machine to add and form, and chock (3) adopts copper alloy bar to process.
Advantage that the utility model compared with prior art has and effect:
1, the utility model integral structure is simple, only need penetrate, screw two major control links during installation, and is easy to use, safe and reliable.
2, the utility model chock when wire clip body screws initiatively shrinks; clamp clue; and the tapering of chock is greater than the tapering of screw thread cover of wedge; clue is clamped in proper order; the protection clue; improved catenary and casted anchor and install and the safety and the reliability of disjunction connection, made the safety performance of whole electrified contacting nets more superior.
3, can prevent that chock from withdrawing from after the utility model wire clip body screws, further improve catenary and casted anchor and install and the safety and the reliability of disjunction connection.

The specific embodiment
1,2,3,4,5 a kind of embodiment of the present utility model is described in conjunction with the accompanying drawings.
A kind of novel bearing rope end anchorage wire clip, constitute by wire clip body (1), screw thread cover of wedge (2) and taper chock (3), the top of wire clip body (1) is " U " type ears, the bottom is a screw thread bush, taper chock (3) is inserted in the internal taper hole on the screw thread cover of wedge (2), the inner of screw thread cover of wedge (2) is contained in the screw thread bush of wire clip body (1) bottom by the external thread rotary on its outer wall, be shaped on connecting bore (6) on " U " type ears on wire clip body (1) top, be fitted with pin (4) on the connecting bore (6).
The outer end of screw thread cover of wedge (2) is shaped on outer six side's boss (7), and the instrument of being convenient to blocks the screw thread cover of wedge, makes its spinning in the screw thread bush of wire clip body (1) bottom.Chock (3) tapering can make clue clamp in proper order greater than the tapering of screw thread cover of wedge (2) internal taper hole, the protection clue.Have anti-skidding screw thread on the inwall of chock (3), axially be evenly equipped with 8 tiny flutings (8), chock can resilient radial be shunk.
Wire clip body (1), screw thread cover of wedge (2) adopt behind the copper alloy forging forming machine to add and form, and chock (3) adopts copper alloy bar to process.
Using method: after catenary (9) passes screw thread cover of wedge (2) internal taper hole, piercing into big end from the small end of chock (3) passes, then with wire clip body (1) spinning the inner in screw thread cover of wedge (2), the male cone (strobilus masculinus) of taper chock (3) is contacted with the inner conical surface of screw thread cover of wedge (2), screwing wire clip body withstands chock and forces chock (3) to move axially, under the effect of screw thread cover of wedge (2) inner conical surface, chock (3) produces radial shrinkage and clamps clue.Withstand chock after wire clip body screws and can prevent that chock from withdrawing from, safety and reliability are higher.On connecting bore (6), be fitted with pin (4) at last, on pin (4), put on spring cotter (5).By pin (4) the utility model is connected with other parts.
