The utility model blocks preburied iron base between two limb pieces of Insulation rail distance keeper.

The utility model, insulation are heightened sleeve and are heightened and be matched in clearance between the spring.

The utility model, be octagonal insulation and heighten that the work plane A of sleeve parallels with work plane C, work plane B parallels with work plane D, work plane C heightens sleeve circle centre distance L4＞work plane D to insulation and heightens sleeve circle centre distance L3 to insulation, work plane D heightens sleeve circle centre distance L3＞work plane B to insulation and heightens sleeve circle centre distance L2 to insulation, and work plane B heightens sleeve circle centre distance L2＞work plane A to insulation and heightens sleeve circle centre distance L1 to insulation.

The utility model insulation is heightened sleeve and is contained in spring and withholds on the toe-end bar, and spacing by being contained in the circlip of withholding in the toe-end ring shaped slot of heightening spring, limits insulation with this and heightens sleeve and withhold toe-end from spring and skid off; Insulation is heightened between sleeve and the spring and to be that matched in clearance, insulation heighten sleeve and can freely rotate on the spring heightening; Insulation is heightened in eight faces of sleeve outer surface, four relative work planes are arranged, the distance at these four work planes and endoporus center is all unequal, Insulation rail distance keeper is contained between preburied iron base and rail, be used for the rail located lateral, different with the matching used track gauge block of existing III type spring is that Insulation rail distance keeper is by two limb piece location, rail vertically on, come spacing by the preburied iron base of two limb interblocks; Transversely come spacing at rail by preburied iron base and rail; In the vertical direction is pressed in two limb pieces of Insulation rail distance keeper upper limit by the middle toe of heightening spring.

When rail need be heightened certain altitude, the rotating insulated sleeve of heightening, correspondence is heightened highly (L1＜L2＜L3＜L4) wherein for L1, L2, L3 or L4, work plane A, work plane B, work plane C or work plane D withhold aerofoil below the rail as work plane, because insulation is heightened sleeve and is directly withheld on rail, rail has been heightened certain altitude, but insulation is heightened the work plane of sleeve and is changed, the height of withholding toe-end of spring does not change, be that buckle press does not change, therefore, heightening elastic bar fastener forms four times of can satisfy rail and heightens.Simultaneously, heighten elastic bar fastener and form the restriction that no longer is subjected on the joint bar space, therefore, heighten the elastic bar fastener composition and realized in the joint and the non-joint of rail general.

The beneficial effects of the utility model are, heighten elastic bar fastener and form three times of can satisfy rail and heighten, and general, simple in structure, easy to install in joint and the non-joint of rail, production application proves the maintenance efficiency that can significantly improve rail track.
