Abstract
The utility model relates to an anti-breakage type contact line central anchor binding clip. The two sides of a clip body (1) are respectively and fixedly provided with a clip plate (2), a central anchor binding rope (9) bypasses a protective ring (3) and is then fixed by a pressing tube (4), and the protective ring (3) is in hinge ring connection with the clip plates (2) through pins (6). When the anti-breakage type contact line central anchor binding clip is applied in a contact net suspension system of a high-speed electrified railway, the scope of compensation of a compensator can be reduced, the scope of accidents can also be reduced, the repair related to the accidents can be facilitated, the repair time for the accidents can be shortened, cables can be prevented from moving towards one side under the external force, and the requirements of the high-speed electrified railway for large tension and high speed are satisfied.
Description
Technical field
The utility model relates to a kind of anti-breaking type contact wire mid point anchor clamp, belongs to high-speed electric railway Catenary Fittings manufacturing technology field.
Background technology
Contact wire mid point anchor clamp in the contact nets in electrified railways centre anchor device is to connect contact wire and catenary at the anchor section middle part of suspension.Its effect is to dwindle the compensator compensates scope, dwindles the accident scope, helps the repairing accident and shortens the break service time; Can prevent that clue is moving to a side string under external force.The contact wire mid point anchor clamp of contact nets in electrified railways use at present generally has two kinds: crimping hair style mid point anchor clamp and anti-serial type mid point anchor clamp.Crimping hair style mid point anchor clamp work loading value is little, and anti-serial type mid point anchor clamp is applicable to low speed, the field of standing.More than two kinds of wire clamps all can not satisfy high-speed electric railway hightension, high-speed requirement.
Summary of the invention
The technical matters that the utility model solves: design a kind of anti-breaking type contact wire mid point anchor clamp, be used for high-speed electric railway overhead contact line system and can dwindle the compensator compensates scope, dwindle the accident scope, help the repairing accident and shorten the break service time, prevent that clue is moving to a side string under external force, satisfy high-speed electric railway hightension, high-speed requirement.
Technical solution of the present utility model: a kind of anti-breaking type contact wire mid point anchor clamp, has wire clip body (1), the both sides of described wire clip body (1) are fixed with clamping plate (2), central anchor is tied knots and is fixed by aluminium hydraulic pressed connecting pipe (4) after (9) walk around retaining ring (3), and retaining ring (3) encircles connection mode by pin (6) with hinge and is connected with clamping plate (2).
Described clamping plate (2) are connected and fixed by bolt (5) and wire clip body (1).
Alternately be shaped on four bolts hole and four tapped bore on the described wire clip body (1), two clamping plate (2) are fastened on the both sides of wire clip body (1) respectively by four bolts (5).
The inboard, lower end of described wire clip body (1) has and the complete adaptive special-shaped hook (11) of the special-shaped hook groove of lead (10).
The surface of described special-shaped hook (11) has anti-slop serrations.
Advantage that the utility model compared with prior art has and effect:
1, the utility model clamping plate are connected and fixed by bolt and wire clip body, and central anchor is tied knots and is connected with two clamping plate with hinge ring connection mode by heart type retaining ring, connects more firm.
2, the utility model wire clip body has the special-shaped hook identical shaped with lead, and has anti-slop serrations on the special-shaped hook, and behind the special-shaped hook groove of contact wire perfect fitting, skidproof effect is better, satisfies the requirement of high-speed electric railway hightension.
3, the utility model is not only easy to install, and the safe reliability height.
Description of drawings
Fig. 1 is a structural front view of the present utility model,
Fig. 2 is a structure birds-eye view of the present utility model,
Fig. 3 is the A-A cutaway view of Fig. 2.
The specific embodiment
1,2,3 a kind of embodiment of the present utility model is described in conjunction with the accompanying drawings.
A kind of anti-breaking type contact wire mid point anchor clamp alternately is shaped on four bolts hole and four tapped bore on its two wire clip bodies 1, two clamping plate 2 are fastened on the both sides of two wire clip bodies 1 respectively by four bolts 5 and four packing rings 8; The inboard, lower end of described two wire clip bodies 1 all has and the complete adaptive special-shaped hook 11 of lead 10 special-shaped hook grooves, and the surface of special-shaped hook 11 has anti-slop serrations, makes wire clip body 1 firm grip contact wire 10.Central anchor ties knots 9, and to walk around heart-shaped retaining ring 3 backs fixing by aluminium hydraulic pressed connecting pipe 4, and two clamping plate, 2 heads have through hole, takes the lead pin 6 to pass through hole and be connected with two clamping plate 2 with hinge ring connection mode, satisfies the tie knots requirement of connection angle variation of central anchor.At last take the lead pin 6 termination suit packing rings 8, penetrate spring cotter 7 and get final product.
The utility model is used for the contact nets in electrified railways suspension to be dwindled the compensator compensates scope, dwindle the accident scope, prevents that clue is under external force to the moving strength member of a side string.
During use, the special-shaped hook 11 of two wire clip body 1 lower ends inboard band anti-slop serrations is put into contact wire 10 special-shaped grooves, align four bolts hole and four tapped bore, two clamping plate 2 that are placed on wire clip body 1 both sides respectively and four packing rings 8 are connected by four bolts 5.Central anchor is tied knots and 9 is walked around heart type retaining ring 3 and be adjacent to its profile, will remain the parallel aluminium hydraulic pressed connecting pipe 4 that penetrates of rope then from the termination, fixes with special-purpose crimping tool crimping.The good heart type retaining ring 3 of crimping is put into two clamping plate 2 open shelves, penetrate and take the lead pin 6, suit packing ring 8, at last spring cotter 7 is penetrated and take the lead in pin 6 end holes, bending spring cotter 7 prevents to take the lead pin 6 to come off, and reaches the 9 bonded assembly effects of tiing knots of contact wire 10 and central anchor.Realization is dwindled the compensator compensates scope, dwindles the accident scope, is prevented that clue is under external force to the moving purpose of a side string.
