Abstract
The utility model relates to a railway track which aims to provide an insulating joint for rails of a railway track. The insulating joint comprises a joint splint, wherein the joint splint is a bar-shaped steel core coated with a housing of insulating materials. The insulating joint for rails of a railway track has the advantages of convenient manufacture, reasonable design, high strength, long service life, simple installation and few components during line use, does not need a special insulating railway gauge block and a strip, can be repeatedly used, and reduces the maintenance work for an engineering affair department.
Description
Technical field
The utility model relates to railroad track, in particular, relates to a kind of railroad track rail insulating joint.
Background technology
The insulating joint that uses on the railroad track rail has various ways such as the insulating joint of splicing, combined type insulating joint at present, but because there are all weak points in its structure or instructions for use.As glued joint insulating joint trouble is installed, to operator's technical requirements height, joint can only disposablely be installed, and can not dismantle again and use.And combined type insulating joint spare and accessory parts comprise a plurality of parts such as plastic spacer, insulation sleeve more, and globality is poor, the stretching resistance deficiency, and the line upkeep workload is big.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of railroad track rail insulating joint is provided.
In order to overcome the above problems, the utility model is achieved through the following technical solutions.
The utility model provides a kind of railroad track rail insulating joint, comprises joint bar, and described joint bar is the strip steel core that has wrapped up insulating material housing.
As a kind of improvement, described joint bar has two, lays respectively at the rail both sides, is bolted to connection.
As a kind of improvement, on the shell of described joint bar, on the surface of inboard, anti-skid design is set.
As a kind of improvement, described joint bar has the profile that adapts with the rail side.
Compared with prior art, the beneficial effects of the utility model are:
The railroad track rail that the utility model provides is easily manufactured, reasonable in design with insulating joint, intensity is high and the life-span is long, install simply in circuit uses, spare and accessory parts are few, do not need special-purpose Insulation rail distance keeper and spring, can reuse, reduce the maintenance work of works department.
Description of drawings
Fig. 1 is the utility model insulating joint mounting structure schematic diagram, is labeled as among the figure: 1 rail, 2 insulating joints, 3 high-strength bolts, 4 high-strength steel washers, 5 track gauge blocks.
Fig. 2 is the insulating joint schematic diagram.
Fig. 3 is the insulating joint sectional view, is labeled as among the figure: 6 shells, 7 strip steel cores.
The specific embodiment
In conjunction with the accompanying drawings, below the utility model is elaborated.
Railroad track rail insulating joint among the embodiment, comprise two joint bars, has the shell 6 that wear-resisting measuring body insulation materials is made, shell 6 is embedded with the strip steel core 7 that high strength steel is made, strip steel core 7 is coated within the shell 6 fully, whole joint bar all insulate, and shell 6 has the various decorative patterns that improve frictional force with rail 1 surperficial position contacting, to improve the stretching resistance of insulating joint.
When making, at first make steel core 7, the method by injection moulding, mold pressing or spraying etc. coats shell 6 then, makes 6 one-tenth on strip steel core 7 and shell as a whole.
At last, it should be noted that the above specific embodiment of the utility model of enumerating.Obviously, the utility model is not limited to above embodiment, and a lot of distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
