The specific embodiment
As depicted in figs. 1 and 2, the 1 clamping contact wire of joint line clamping plate, joint wire clamp connecting panel 2 couples together joint line clamping plate 1 and connecting panel 3 by fastening gauge member 9, and connecting panel 3 couples together by the monaural on fastening gauge member 9 and the framework 6.Whole framework 6 is a welding structural element, is connected with long slide plate 10, short slide plate 4 by fastening gauge member 9 on the framework 6, and long slide plate 10, short slide plate 4 constitute the water conservancy diversion slideway, is welded with starting rod A5, starting rod B5 on long slide plate 10, the short slide plate 4 and constitutes the extinguishing arc horn gap.Connecting panel 3 bottoms are the large radius arc transition, can make pantograph be smoothly transitted into the water conservancy diversion slideway from the contact wire bottom along certain slope; Middle part silicon rubber insulator 8 its end machining of two ends crimping armor clamp have screw thread, couple together with framework 6, four openings that connect the fluent road of insulation slide plate 7 confined beds on the silicon rubber insulator 8, restriction pantograph attitude, avoid scraping bow, beat the bow phenomenon, the two ends of water conservancy diversion slideway are great circle arcuation K/UP, and under dynamic pressure, pantograph can smoothly be passed through at a high speed.
The 1 clamping contact wire of joint line clamping plate, when locomotive passes through, pantograph carries out the transition to the water conservancy diversion slideway gradually along the bottom circular arc of joint wire clamp connecting panel 2 and connecting panel 3, its gradient is 2%, pantograph by the time only contact water conservancy diversion slideway and insulation slideway, water conservancy diversion slideway bottom is high, silicon rubber insulator 8 bottoms are low, make water conservancy diversion slideway bottom have the discrepancy in elevation, do not contact silicon rubber insulator 8, thereby there is not pollution problem in silicon rubber insulator 8 with silicon rubber insulator 8 bottoms.
6 formed deads in line of bolt on silicon rubber insulator 8 axis and the connecting panel 3 and overlap with the groove of contact wire, thereby this structural segmented shackle is pure tension state when lead is subjected to tension force, do not produce moment of flexure.
