Abstract
The utility model refers to devices of an electric railway catenary, in particular to a translation arm supporting device. Arms of prior art plane supporting structures are of stable trigonometry structure and can swing along the line direction, which are used only in the expansion of the catenary when the compensation temperature is changed. The arm structure can not slide up and down along a strut. When the arm structure is used in the parallel translation catenary, the contact wire is liable to retort thus influence the system stability. The arm device of the utility model adopts a parallelogram combination arm structure with a crank sliding guide mechanism, therefore during the horizontal moving process of support catenary, the consistency of the contact wire height and smoothness of the movement can be ensured and the contact wire can also be prevented from distorting so that the stability of the catenary parallel moving system is guarantied, which is suitable for parallel moving catenaries.

The specific embodiment
Referring to Fig. 1, existing Horizontal Cantilever underwork is used to support electrification railway contact net catenary and contact wire, mainly is made up of Horizontal Cantilever, oblique wrist and arm and insulator.Bracket is stable three-legged structure, can be along the line direction swing, and contact system is flexible when only being used for compensates, and cantilever structure can not slide up and down along pillar, easily causes contact wire to reverse when being used for parallel mobile catenary, influences the stability of system.Therefore, existing Horizontal Cantilever underwork can not be used as the mobile catenary bracing or strutting arrangement.
The utility model translation bracket underwork aims at and can design by parallel mobile contact net system; compare with existing contact system Horizontal Cantilever underwork, have can slide up and down along pillar, move steadily, protection contact wire do not deform, guarantees that the parallel mobile system of contact system is stable.
Referring to Fig. 2, Fig. 2 parallelogram combination cantilever structure schematic diagram, principle of work is: mechanism size satisfies and concerns AB=BC=BD, when slide block along perpendicular line (pillar) when sliding up and down, rod end point D makes accurate straight-line motion along horizon.CD=EF in the mechanism, CF=DE, bar, slide block, bar and member constitute parallel-crank mechanism, and therefore, member is made accurate linear translational motion with rod end point D along horizon.
Translation bracket underwork is taked parallelogram (four connecting rods) mechanism parallel motion mode, contact system its geometric configuration in moving process can not change under this mode, the contact system moving process do not have fatigue, zero damage, safety, reliable, the life-span is long, maintenance workload is little, operating cost is low.
Referring to Fig. 3, Fig. 4, translation bracket supportive device, comprise pillar 1, bracket device 2, described bracket device 2 adopts the parallelogram combination cantilever structure of band slide crank frame mechanism, one end of the flexible armed lever 3 of the parallelogram of bracket device 2 is hinged on the balladeur train 4, and contact system suspension member 5 is set on its other end, and catenary and contact wire steady arm 10 are set on the suspension member 5; The upward flexible armed lever and the crank connecting link 6 of bracket device 2 are hinged, and described balladeur train 4 is arranged in the chute of pillar 1, and is connected with traction steel wire 7.
Under the haulage cable tension, the contact wire that hangs on hanger is positioned at the railway center, for locomotive by the time get stream, when haulage cable slowly loosened tension force, clump weight slowly descended and drives cantilever structure by parts effects such as hanger balladeur train, pulleys and bounces back to the pillar side; On the contrary, haulage cable makes the parallel railway center that moves to of hanger by promoting clump weight when being subjected to pulling force.
In order to realize steadily moving of contact system, clump weight 8 is set on balladeur train 4, traction steel wire 7 is connected by the interior balladeur train 4 of pulley 9 and chute.
But the translation contact system adopts the parallelogram combination cantilever structure of band slider-crank mechanism, mobile catenary hangs on the connecting rod (overhead contact line locating support) of parallel-crank mechanism, the contact wire registration device also is installed on this connecting rod, therefore when driving sliding block is moved, just can realize the translation of contact system.In this operating process, the geometric configuration of contact system can not change, and has ensured the contact system stability of structure.
