Abstract
The utility model relates to a railway track, which aims to provide a combined bushing used for a concrete pillow of the railway track. The combined bushing used for the concrete pillow of the railway track comprises a housing made of molding materials; a metal nut is embedded in the housing to ensure the mechanical strength and the pull-out force of the screw thread part. The combined bushing has the advantages of easy manufacture, good compatibility with the prior concrete pillow, reasonable design, high strength and long service life, and can prolong the service life of the concrete pillow, and better ensure the safety of driving.
Description
Technical field
The utility model relates to railroad track, in particular, relates to a kind of railroad track concrete crosstie assembled casing.
Background technology
The plastic bushing that uses on the railroad track concrete crosstie all uses the plastics manufacturing at present.Because be subjected to the restriction of material and structure, its mechanical performance can not satisfy instructions for use fully, because the influence of various force-bearing situations, sliding tooth is arranged, be pulled out etc. damaged phenomenon, influences the application life of concrete crosstie, influences traffic safety simultaneously in the middle of use for it.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of railroad track concrete crosstie assembled casing 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 concrete crosstie assembled casing, comprises the shell that injected plastics material is made, and shell is embedded with the nut of metal, guarantees the mechanical strength and the uplift resistance of threaded portion.
As a kind of improvement, the external surface of described shell vertically have one or more stairsteppings, increase the uplift resistance of sleeve pipe.
As a kind of improvement, the external surface of described shell is polyhedral shape, and sleeve pipe did not change when the shape of anti-rotation guaranteed railway spike bolt screwin.
As a kind of improvement, the external surface of described shell is spirochetal shape, and sleeve pipe did not change when the shape of anti-rotation guaranteed railway spike bolt screwin.
As a kind of improvement, the external surface of described shell has some small embossments or pit, increases sleeve pipe and concrete mating face, guarantees its bond strength.
Compared with prior art, the beneficial effects of the utility model are:
The railroad track concrete crosstie that the utility model provides is easily manufactured with novel assembled casing, good, reasonable in design with existing concrete pillow compatibility, intensity is high and the life-span is long, can improve the application life of concrete crosstie, guarantees traffic safety better.
Description of drawings
Fig. 1 is the utility model assembled casing external structure schematic diagram.
Fig. 2 is the sectional view of assembled casing among Fig. 1.
Fig. 3 is the scheme of installation of assembled casing in the utility model.
Reference numeral is among the figure: 1 shell, 2 nuts, 3 concrete crossties.
The specific embodiment
In conjunction with the accompanying drawings, below the utility model is elaborated.
Railroad track concrete crosstie assembled casing among the embodiment comprises the shell 1 that injected plastics material is made, and shell 1 is embedded with the nut 2 that metal is made, and can certainly make of other high-strength material.The external surface of shell 1 vertically have a stairstepping, increase the uplift resistance of sleeve pipe, can certainly make a plurality of stairsteppings.The external surface of shell 1 is polyhedral shape, and sleeve pipe did not change when the shape of anti-rotation guaranteed railway spike bolt screwin, can adopt spirochetal shape yet.The external surface of shell 1 has some small embossments or pit, increases sleeve pipe and concrete mating face, guarantees its bond strength.
When making, at first make nut 2, then by the method moulding of injection moulding, make 1 one-tenth on nut 2 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.
Claims (5)
1, a kind of railroad track concrete crosstie assembled casing comprises the shell that injected plastics material is made, and it is characterized in that shell is embedded with the nut of metal.
2, railroad track concrete crosstie assembled casing according to claim 1 is characterized in that, the external surface of described shell vertically have one or more stairsteppings.
