Abstract
The utility model provides a force-bearing cable dropper clamp for an integral dropper, which comprises a main body (1), a hoisting ring (2), a bolt (3), a nut (4) and a check washer (5), wherein the top of the main body (1) is an arc-shaped segment for covering a force-bearing cable (6); and two straight edges (7) of the lower part of the main body are connected with two arms (9) which are positioned at the upper part of the hoisting ring (2) through the bolt (3), the nut (4) and the check washer (5). Compared with the prior art, the utility model has the advantages that the coverage range of the force-bearing cable by the arc-shaped segment of the main body is more than 180 degrees, so as to that effectively fasten the force-bearing cable, ensure that the force-bearing cable can be stably mounted without needing auxiliary inserted pins, simplify the structure, reduce the weight, shorten the manufacturing cycle, and provide much convenience for production, installation, debugging and maintenance.
Description
Technical field
The utility model belongs to contact nets in electrified railways part technical field, is specifically related to a kind of dropper catenary hanger ear.
Background technology
Dropper is used for the contact nets in electrified railways overhead contact line with catenary and suspends contact wire in midair.One end is connected with the copper-alloy stranded conductor catenary, and the other end is connected with copper alloy contact wire.The catenary hanger ear is fixed on the catenary, connects the suspention contact wire by dropper line, contact wire hanger ear etc.The dropper of contact nets in electrified railways mainly contains with the catenary hanger ear and forges two-piece type, hinge-type, U type band bolt-type at present.It is open forging two-piece type catenary hanger ear and catenary connecting portion, and catenary is not wrapped in the wire clamp fully, and bolt looseness easily comes off, and has potential safety hazard, and quality is heavier.The clamping plate of hinge-type catenary hanger ear and intermediate connector adopt tiny rivet hinged, riveted joint place has tearing tendency under long-term complex loading conditions, and install and be subjected to force unbalance after stressed, wire clamp easily takes place reverse and then damage the dropper line, have big potential safety hazard.U type band bolt-type catenary hanger ear adopts strip to strike out U type structure, and catenary is wrapped in the wire clamp fully, and by the auxiliary clamping catenary of latch, light weight, safety are good, and being that general fast railway is a large amount of adopts a kind of structures.But it is installed clamping and must rely on latch to assist, the structure relative complex, and it is not too convenient to install.
Summary of the invention
The technical matters that the utility model solves: design a kind of dropper catenary hanger ear,, remove auxiliary bolt, make that structure is simpler, installation is more convenient by optimized Structure Design.
Technical solution of the present utility model: a kind of dropper catenary hanger ear is made of body (1), suspension ring (2), bolt (3), nut (4) and stop washer (5); The top of described body (1) is for coating the arc section (8) of catenary (6), and bottom two straight flanges (7) are connected with suspension ring (2) top two limbs (9) by bolt (3), nut (4) and stop washer (5).
Described body (1) bottom two straight flanges (7) from its upper end cross with arc section (8) points of tangency after bend inwards, make top arc section (8) to the coating face of catenary (6) greater than 180 °.
The utility model compared with prior art the body arc section to the coating face of catenary greater than 180 °, can more effectively hold catenary tightly, do not need auxiliary bolt firmly to install, simplify the structure, alleviated quality, shortened the manufacturing cycle, made production, install, debug and keeped in repair more convenient.

Fig. 1 is a structural front view of the present utility model,
Fig. 2 is a structure right elevation of the present utility model.
The specific embodiment
1,2 a kind of embodiment of the present utility model is described in conjunction with the accompanying drawings.
A kind of contact nets in electrified railways part---dropper catenary hanger ear is made of body 1, suspension ring 2, bolt 3, nut 4 and stop washer 5; The top of described body 1 is for coating the arc section 8 of catenary 6, and bottom two straight flanges 7 are connected with suspension ring 2 tops two limbs 9 by bolt 3, nut 4 and stop washer 5.Two straight flanges 7 of described body 1 are not tangent with arc section 8, but body 1 bottom two straight flanges 7 from its upper end cross with arc section 8 points of tangency after bend inwards, the coating face that makes 8 pairs of catenarys 6 of top arc section is greater than 180 °, more effectively hold catenary tightly, be issued to firm installation in the situation that does not increase auxiliary bolt, can satisfy catenary again and snap in smoothly.
During installation, catenary 6 is snapped in the arc section 8 of body 1, make the arc surface and the catenary arc surface closed contact of the inboard of arc section 8.Two limbs 9 with suspension ring 2 straddle on two straight flanges 7 of body 1 then, between the two by after connecting with bolt 3, nut 4 and stop washer 5, and the long limb of first bending both sides stop washer 5, and closely be adjacent to body 1; Clamp nut 4 is to the moment required value, the manomelia of bending both sides stop washer 5, and closely be adjacent to six aspects of nut 4 and bolt 3 heads.Long limb, manomelia by stop washer 5 have cooperated the locking effect of stop with body 1 dual-side, nut 4 and 3 sides of bolt respectively.
Claims (2)
1. dropper catenary hanger ear is characterized in that: described wire clamp is made of body (1), suspension ring (2), bolt (3), nut (4) and stop washer (5); The top of described body (1) is for coating the arc section (8) of catenary (6), and bottom two straight flanges (7) are connected with suspension ring (2) top two limbs (9) by bolt (3), nut (4) and stop washer (5).
2. dropper catenary hanger ear according to claim 1, it is characterized in that: described body (1) bottom two straight flanges (7) from its upper end cross with arc section (8) points of tangency after bend inwards, make top arc section (8) to the coating face of catenary (6) greater than 180 °.
