Abstract

The utility model discloses a rail heightening elastic strip fastener which can be used repeatedly, comprising an elastic strip, an heightening sleeve, a gauge block, an heightening base plate, an insulating base plate and a pre-buried seat, and is characterized in that the toe end of the elastic strip is riveted with the heightening sleeve which is arranged on the gauge block above the rail; as a further improvement of the utility model, the heightening sleeve is a steel part. The utility model has the advantages of good reliability, convenient integral disassembly, repeated use and simple operation.

Description

Reused rail is heightened elastic bar fastener

Technical field

The utility model relates to a kind of elastic bar fastener of heightening that is used for rail.

Background technology

Heighten elastic bar fastener and be used for fixing rail, the patent No. is: 200720078328.0 utility model discloses a kind of formula rail elastic bar fastener of heightening, comprise spring 11, heighten sleeve 12, track gauge block 13, height adjusting cushion plate 14, insulating pad 15 and pre-buried seat 16, heightening sleeve 12 is installed on the rail, toe-end at spring 11 is provided with downward seam, the endoporus of heightening sleeve 12 is provided with the step that matches with seam, according to the different amounts of heightening, contact with rail by heightening sleeve 12 different bases, reach the purpose of heightening, spring is to the buckle press of rail when using with assurance; This structure need not other parts such as alignment pin, and used part is minimum, use is easy to maintenance, cost is lower, but has the possibility of spring 11 slippage from heighten sleeve 12, and its reliability can't be protected, and also is not easy to integral demounting; And heighten sleeve 12 and generally adopt plastic cement material, easy to wear, need frequently to change; Track gauge block 13 comes off easily, need be special, and the part that site operation need be changed is many, complicated operation.

The utility model content

The purpose of this utility model is the above-mentioned deficiency at prior art, provides a kind of reused rail to heighten elastic bar fastener, and it has good reliability, is convenient to integral demounting, advantage reusable, simple to operate.

For achieving the above object, reused rail of the present utility model is heightened elastic bar fastener, comprise spring, heighten sleeve, track gauge block, height adjusting cushion plate, insulating pad and pre-buried seat, it is characterized in that described spring and heighten the sleeve riveted joint, heighten on the track gauge block that sleeve is installed on the rail top;

Since the toe-end of spring with heighten the sleeve riveted joint, so spring can't slippage from heighten sleeve, good reliability is convenient to integral demounting; While can be utilized the track gauge block of original normal use, and the convenience when making things convenient for the adjustment of gauge and constructing use can not come off, and installs to connect reliably;

As further improvement of the utility model, the described sleeve of heightening is a steel part, and abrasion resistance is good, and is reusable.

In sum, the utlity model has good reliability, be convenient to integral demounting, advantage reusable, simple to operate.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Embodiment one

By Fig. 3, Fig. 4 and shown in Figure 5, the reused rail of this embodiment is heightened elastic bar fastener, what comprise spring 1, steel heightens sleeve 2, track gauge block 3, height adjusting cushion plate 4, insulating pad 5 and pre-buried seat 6, wherein spring 1 is an III type spring, the projection 7 of described spring 1 by being located at its toe-end with heighten sleeve 2 riveted joints, heighten on the track gauge block 3 that sleeve 2 is installed on the rail top; Because spring 1 can't slippage from heighten sleeve 2, good reliability is convenient to integral demounting; The abrasion resistance of heightening sleeve 2 is good, reusable.

Embodiment two

By shown in Figure 6, the difference that the reused rail of this embodiment is heightened elastic bar fastener and embodiment one only is that spring 8 is IV type spring, and its former straightway 8a indent can be used for high-speed railway.

Claims

1. elastic bar fastener is heightened in a reused rail road, comprise spring, heighten sleeve, track gauge block, height adjusting cushion plate, insulating pad and pre-buried seat, the toe-end that it is characterized in that spring with heighten the sleeve riveted joint, heighten on the track gauge block that sleeve is installed on the rail top.

2. reused rail as claimed in claim 1 is heightened elastic bar fastener, it is characterized in that the described sleeve of heightening is a steel part.
