Abstract

The utility model provides an e-shaped elastic strip of a railway track, which comprises an elastic strip body, wherein the elastic strip body comprises a supporting arm, a first bent part, a connecting arm, a second bent part and a pressing arm, the supporting arm, the first bent part, the connecting arm, the second bent part and the pressing arm are integrally formed and sequentially connected, the supporting arm is used for being connected with an embedded iron seat, the pressing arm is used for pressing and holding a rail, and the cross sectional area of any position of the first bent part is larger than that of the connecting arm and that of the pressing arm. Because the cross-sectional area of the optional position of first kink all is greater than the cross section of linking arm and is greater than the cross-sectional area of support arm to increased the intensity of first kink, when railway rails e type bullet strip takes place elastic deformation like this, first kink can bear stronger torsional force, just so be difficult to the breaking occur, prolonged life, guaranteed the transportation safety of railway.

Description

E-shaped elastic strip for railway track

Technical Field

The utility model relates to the field of railway accessories, in particular to an e-shaped elastic strip for a railway track.

Background

Railway rails are components that support and orient locomotives, and are secured to the sleepers of the track bed by resilient fasteners. The cramping piece of elasticity fastener is mainly the bullet strip, it is crooked and distortion through the bullet strip, produce the cramping effect on the track, guarantee the reliable connection between the rail effectively for a long time, keep orbital wholeness as far as possible, prevent the rail for the vertical lateral shifting of sleeper, but current E type bullet strip is formed by all being through the processing of the billet bending deformation that the diameter is the same, stress is all concentrated at the kink like this, and the kink that is close to pre-buried iron seat one end is the region that mainly plays the elastic action again, the crookedness is the biggest, stress is most concentrated, so the rupture phenomenon can often take place, just so need often change the bullet strip, waste time and energy.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems in the prior art, the utility model provides the e-shaped elastic strip of the railway track, which has higher strength in a bending area and is not easy to break.

The utility model provides an e-shaped elastic strip of a railway track, which comprises an elastic strip body, wherein the elastic strip body comprises a supporting arm, a first bending part, a connecting arm, a second bending part and a pressing arm, the supporting arm, the first bending part, the connecting arm, the second bending part and the pressing arm are integrally formed and sequentially connected, the supporting arm is used for being connected with an embedded iron seat, and the cross sectional area of any position of the first bending part is larger than that of the connecting arm and that of the supporting arm.

As a further improvement of the utility model, the cross section of any position of the first bending part is a circular structure.

As a further improvement of the present invention, the first bending portion includes a bending region and transition regions disposed at two ends of the bending region, the transition regions at two ends of the bending region are respectively connected to the connecting arm and the supporting arm, and the transition regions are of a structure with gradually changing diameters.

As a further improvement of the present invention, the first bent portion includes a base bent portion and a reinforcing rib disposed on a side surface of the base bent portion.

The utility model has the beneficial effects that: because the cross-sectional area of the optional position of first kink all is greater than the cross-section of linking arm and is greater than the cross-sectional area of support arm to the intensity of first kink has been increased, the cross-sectional area of first kink can be greater than one hundredth, three hundredths or five hundredths etc. of linking arm and support arm cross-sectional area, and when railway rails e type bullet strip took place elastic deformation like this, first kink can bear stronger torsional force, just so be difficult to the breaking, has prolonged life, has guaranteed the transportation safety of railway.

Detailed Description

As shown in fig. 1 to 3, the utility model discloses an e-shaped elastic strip for a railway track, which comprises an elastic strip body, wherein the elastic strip body comprises a supporting arm 1, a first bending part 2, a connecting arm 3, a second bending part 4 and a pressing arm 5, the supporting arm 1, the first bending part 2, the connecting arm 3, the second bending part 4 and the pressing arm 5 are integrally formed and sequentially connected, the supporting arm 1 is used for being connected with an embedded iron seat 6, and the cross sectional area of any position of the first bending part 2 is larger than that of the connecting arm 3 and that of the supporting arm 1. Because the cross-sectional area of the optional position of first kink 2 all is greater than the cross-section of linking arm 3 and is greater than the cross-sectional area of support arm 1 to increased the intensity of first kink 2, when railway rails e type bullet strip takes place elastic deformation like this, first kink 2 can bear stronger torsional force, just so be difficult to the breaking occur, prolonged life, guaranteed the transportation safety of railway.

In this technical solution, the cross section of any position of the first bending part 2 is a circular structure. Its this railway rails e type bullet strip carries out high temperature heating through the same reinforcing bar of whole root diameter, and rethread processing equipment rubs first kink 2's both ends with the hands thin, buckles into e type bullet strip at last again, just so can guarantee that the diameter of first kink 2 is greater than the linking arm 3 at both ends and the diameter of support arm 1, has reduced the stress influence, has guaranteed the intensity that e type bullet strip.

In this technical scheme, first kink 2 includes the bending zone and locates the transition district at bending zone both ends, the transition district at bending zone both ends respectively with linking arm 3 and support arm 1 are connected, the transition district is diameter gradual change structure, can guarantee the wholeness and the structural strength of e type bullet strip like this.

In some embodiments, the first bent portion 2 includes a base bent portion and a reinforcing rib disposed on a side of the base bent portion, so that the strength of the first bent portion 2 is improved by disposing the reinforcing rib, and the shape of the reinforcing rib and the direction of the base bent portion are the same.

The diameter of the first bending part 2 is increased to increase the structural strength, and the e-shaped elastic strip is simple in structure, low in manufacturing cost, not prone to fracture, long in service life and capable of guaranteeing the transportation safety of railways.

The foregoing is a more detailed description of the utility model in connection with specific preferred embodiments and it is not intended that the utility model be limited to these specific details. For those skilled in the art to which the utility model pertains, several simple deductions or substitutions can be made without departing from the spirit of the utility model, and all shall be considered as belonging to the protection scope of the utility model.
