The specific embodiment
1,2,3,4,9 first kind of embodiment of the present invention---jackscrew type termination fitting for contact wire is described in conjunction with the accompanying drawings.
A kind of jackscrew type termination fitting for contact wire is made of terminal ears (1), screw thread bush (2), chock (3), screw thread cover of wedge (4) and briquetting (5).The inner of terminal ears (1) is shaped on through hole (13), and is shaped on outside thread on its outer wall; Be shaped on taper hole (14) on the screw thread cover of wedge (4), and be shaped on outside thread on its inner outer wall, the outer end is outer hexagon; Have negative thread on the two ends inwall of screw thread bush (2), be shaped on outer hexagon (16) on the outer wall, the middle part is shaped on the boss (15) of symmetry, and the interior outer face of boss (15) is the inclined-plane that is parallel to each other with screw thread cover of wedge (4) inner conical surface, boss (15) is gone up symmetry and is shaped on inner bolt hole (8), and inner bolt hole (8) is perpendicular to the interior outer face of boss (15); Briquetting (5) inboard curved, the outside is the inclined-plane that is parallel to each other with screw thread cover of wedge (4) inner conical surface.Taper chock (3) is positioned at the taper hole (14) on the screw thread cover of wedge (4), passes through cone match between the two.The inner of screw thread cover of wedge (4) is contained in an end of screw thread bush (2) by the external thread rotary on it, the inner of terminal ears (1) is contained in the other end of screw thread bush (2) by the external thread rotary on it, briquetting (5) is symmetricly set in the screw thread bush (2) and is positioned between terminal ears (1) and the taper chock (3), and the inclined-plane of briquetting (5) inclined-plane, the outside and boss (15) the inner is close to, be installed with bolt (6) on the inner bolt hole (8), the inner of bolt (6) is pressed on the inclined-plane, the outside of briquetting (5), is installed with black nut (7) on the bolt (6) and black nut (7) is pressed on the outer face of boss (15).The outer end of terminal ears (1) is shaped on connecting bore (9), is fitted with pin (10) on the connecting bore (9).
Terminal ears (1), screw thread bush (2) and screw thread cover of wedge (4) adopt behind the copper bar material forging forming machine to add and form; Chock (3), briquetting (5) adopt Corson alloy to process.All have anti-skidding screw thread on the inside and outside wall of chock (3), axially be evenly equipped with 4 tiny flutings (17), chock (3) can resilient radial be shunk.
Using method: contact wire (19) is passed chock (3) endoporus by the taper hole (14) on the screw thread cover of wedge (4) and pass from the big end of chock (3), and guarantee that contact wire stretches out chock (3) large end face 60mm, strike with hammer then and make chock (3) male cone (strobilus masculinus) and screw thread cover of wedge (4) internal taper hole face closely connected, make chock (3) resilient radial contraction clip close contact line; Then with the inner spinning of screw thread cover of wedge (4) a end at screw thread bush (2), again briquetting (5) is put into screw thread bush (2), and the small end face that guarantees briquetting (5) contacts with chock (3) large end face, the inboard cambered surface of briquetting (5) is close to that inclined-plane, the outside is right against puller bolt (6) on the outer wall of contact wire (19), and pretension bolt withstands briquetting (5) and prevents its rotation.With the inner spinning of terminal ears (1) the other end in screw thread bush (2), promote briquetting (5) thus promoting chock (3) moves axially, the one, force the inner conical surface effect of the male cone (strobilus masculinus) and the screw thread cover of wedge (4) of chock (3), chock (3) radial shrinkage further clamps contact wire, two is that two briquettings (5) move axially the lateral surface that the inner end surface that forces boss (15) acts on two briquettings (5), by the inboard cambered surface clamping contact wire of two briquettings (5).Screw bolt (6) and force briquetting (5) to move radially, clamp contact wire once more.Fastening nut (7) prevents that bolt (6) is loosening.Go up plug-in mounting pin (10) at connecting bore (9) at last, on pin (10), put on β pin (18), the present invention is connected with other parts by pin (10).
5,6,7,8,9 second kind of embodiment of the present invention---jackscrew type termination fitting for catenary is described in conjunction with the accompanying drawings.
Its basic structure is identical with first kind of embodiment, and difference is: be shaped on annular groove (11) on the outer wall of chock (3), snap ring (12) is housed on the annular groove (11).Preventing that outer monofilament (21) behind catenary (20) wire stripping from snapping in the fluting (17) of chock (3) influence the chock contraction.
Using method: after catenary (20) passes screw thread cover of wedge (4) outer end, 60mm is cut short in the outer strip off of catenary, make catenary internal layer twisted wire pass chock (3) endoporus, then chock (3) is moved axially between the inside and outside layer of the catenary of strip off, make the catenary skin be positioned at the periphery of snap ring (12), and guarantee that catenary internal layer twisted wire stretches out chock (3) large end face 60mm.Chock (3) moves together with catenary its male cone (strobilus masculinus) and screw thread cover of wedge (4) inner conical surface is adjacent to, and strikes with hammer then to make chock (3) make chock (3) resilient radial shrink the clamping catenary; Then with the inner spinning of screw thread cover of wedge (4) a end at screw thread bush (2), again briquetting (5) is put into screw thread bush (2), and the small end face that guarantees briquetting (5) contacts with chock (3) large end face, the inboard cambered surface of briquetting (5) is close on the outer wall of catenary (19) internal layer twisted wire, outer side plane is right against puller bolt (6), pretension bolt withstands briquetting (5), prevents its rotation.With the inner spinning of terminal ears (1) the other end in screw thread bush (2), promote briquetting (5) thus promoting chock (3) moves axially, the one, force the inner conical surface effect of the male cone (strobilus masculinus) and the screw thread cover of wedge (4) of chock (3), chock (3) radial shrinkage further clamps catenary, two is that two briquettings (5) move axially the lateral surface that the inner end surface that forces boss (15) acts on two briquettings (5), by the inboard cambered surface clamping catenary of two briquettings (5).Screw bolt (6) and force briquetting (5) to move radially, clamp catenary once more.Fastening nut (7) prevents that bolt (6) is loosening.Go up plug-in mounting pin (10) at connecting bore (9) at last, on pin (10), put on β pin (18), the present invention is connected with other parts by pin (10).
