Abstract

The utility model relates to a steel rail clip, in particular to a deforming clip which has a constant section and one step, and can smooth the rail surface when the steel rail produces the high-low staggered problem, and can reduce impacts of the steel rail joints when the wheels pass through, and improves the stability of trains. For the high-low staggered problem caused by the replacement of the steel rails and the crosses after being damaged in the busy driving areas with the short rails which have the homogeneous rail style and more overall weight passed, the rail surface can be smoothed, shocks of joints generated by wheels are reduced, the maintaining period is prolonged, the maintaining workload is decreased, the quality of equipment is improved, the operational stationarity of trains is enhanced, the transport interferences are reduced, the transport benefit is improved after using the clip.

Description

A kind of Deformation clamping plate

The utility model relates to a kind of railways splint, and especially a kind of uniform section and have a step when rail height occurs and grinds one's teeth problem, can make rail level smooth-going, can reduce wheel by the time to the impact of rail joint, increase the Deformation clamping plate of train stability.

In the track overall structure, joint bar is main connected component, and the globality that keeps track is played an important role.With clamping plate and bolt rail is linked up, make joint area as far as possible with other position the same can bear train by the time huge bending moment and lateral force.At present, technique known is to adopt double end symmetry clamping plate, when rail type of the same race connects, adopts straight clamping plate and fish tail type clamping plate, as shown in Figure 1.

Along with the improving constantly of train running speed, increase that axle is heavy, and the rise of freight volume, the wheel pressure that rail is born increases, and the impact force of joint increases, and the pressure of rail falls into or abrasion are accelerated, and hurt is accelerated.This situation is particularly outstanding in the electrified sharp radius curve of short rail mountain area heavy duty location, makes a large amount of rail owing to hurt (nuclear wound, palpebral fissure and abrasion) is forced to change.It is different with the vertical mill degree of rail on the circuit to form the new rail of changing like this, thereby causes rail joint just to grind one's teeth.As shown in Figure 2, cause existing rail 1 owing to switch tracks and newly change rail 2 rail level irregularities (mill that hangs down is different), produced the h that just grinds one's teeth, use the common clamping plate 3 of double end symmetry to connect, when train by existing rail 1 when newly changing rail 2 transition, wheel produces a pressure to existing rail 1 under the effect of goods and deadweight, make existing rail 1 and newly change step of rail 2 meeting generations, because the existence that height is ground one's teeth, strengthened the degree of this step, thereby when making wheel pass through rail gap 4, produce bigger impact force to newly changing rail 2.It is smooth-going that this joint disease can't fundamentally be adjusted rail level with existing joint bar, thereby more aggravated the impact force of butt joint when train passes through, shortened equipment (locomotive, vehicle and track), especially application life of track (rail, sleeper and connected component), increased maintenance load, and directly threaten traffic safety, influence the raising of transport benefits.

The purpose of this utility model is that a kind of railways splint will be provided, especially a kind of uniform section and have a step when rail height occurs and grinds one's teeth problem, can make rail level smooth-going, can reduce wheel by the time to the impact of rail joint, increase the Deformation clamping plate of train stability.

The purpose of this utility model is achieved in that a kind of Deformation clamping plate, on the clamping plate center line, be provided with the through hole that is complementary with rail, wherein, described clamping plate comprise first section, second section and linkage section, first section width with second section of its middle clamp plate is identical, and the step that staggers is connected by means of a linkage section that tilts first, second section with clamping plate.

Having wide range of applications of the Deformation clamping plate that the utility model proposes, busy for driving, by the short rail location of the many rail types of the same race of gross weight, the height of changing after rail and the railway frog hurt and the causing problem of grinding one's teeth, can make rail level smooth-going after using these clamping plate, alleviate the impact force of wheel butt joint place, prolong to support and repair the cycle, reduce the maintenance work amount, prolong the application life of rail and equipment, improve equipment quality, strengthen the stationarity of train operation, reduce transportation and disturb, improve transport benefits.

Concrete structure of the present utility model is provided by following drawings and Examples.

Below in conjunction with accompanying drawing and most preferred embodiment the concrete structure that the utility model proposes is further described.

Extremely shown in Figure 7 as Fig. 3, a kind of Deformation clamping plate 6 that the utility model proposes, on the clamping plate center line, be provided with the through hole 7 that is complementary with rail, wherein, described Deformation clamping plate 6 comprises first section 5, second sections 9 and linkage section 8, first section 5 width with second section 9 of its middle clamp plate is identical, and the step that staggers, and is connected by means of a linkage section 8 that tilts first, second section with clamping plate.

Described Deformation clamping plate 6 side 10 along its length is complementary with the web of the rail, and opposite side 11 parallels with it, and an inclined-

plane

12,13 is upwards formed at top.

Described Deformation clamping plate 6 wherein one section inclined-plane 12 greater than the inclined-plane 13 of another section.

One section clamping plate 5 along continuous straight runs that a described skew back face is big are higher than one section little clamping plate 9 of inclined-plane.

During use, the end flange of rail pad of existing rail 1 is risen, and that Deformation clamping plate 6 along continuous straight runs are slightly high first section links by means of bolt and existing rail 1, second section by means of bolt with newly change rail 2 and link, thereby make the rail level of joint smooth-going, alleviate the impact force of wheel it.

First section of above-mentioned Deformation clamping plate 6 with second section symmetry, can determine the specification of required Deformation clamping plate according to the type of actual rail, size, existing rail that height is ground one's teeth and the position of newly changing rail.This Deformation clamping plate is can be whole rolling, casting or machine are made.
