Abstract

An iron floor plate capable of preventing over mounting of an elastic strip is arranged between a sleeper and a rail, and comprises a plate body with a bolt hole, and elastic strip mounting seats provided with through holes and fixed onto two sides of the plate body. The iron floor plate is characterized in that a limiting dog is additionally arranged at the elastic strip outlet end of the elastic strip mounting seat. The iron floor plate has the benefits that the structure is simple, the design of an existing iron floor plate is not changed, only a limiting device is needed to be arranged in the structure of the original iron floor plate, and a big problem in practice is solved, so that an effect of doing more with less efforts can be realized; the experiments of three million coupler assembly fatigue shows that the result is good, and the property of the elastic strip is not influenced.

Description

A kind ofly prevent that spring from crossing the iron chair of installation

Technical field

The utility model belongs to the railway track fastener field, relates in railway rail clip the iron chair for fixed rail, particularly a kind ofly prevents that spring from crossing the iron chair of installation.

Background technology

Fastener is for connecting rail and sleeper, rail is fixed on sleeper, fastener comprises iron chair, spring, rubber mat plate, nylon part, bolt etc., spring is arranged in iron chair spring hole, pass through elastic deformation, rail is produced to a downward pressure, fix rail and prevent that rail from rocking through out-of-date generation at train.The bending that the structure of spring is similar e type, as shown in Figure 1, after spring inserts in the spring installing hole, between sweep and spring mount pad, the regulation design gaps is 8-10mm.Because train can produce outside tension force to rail, rail can produce corresponding active force to spring simultaneously, if be less than this design gaps, train is through out-of-date, particularly, at the train turning, this active force can be concentrated the bending place that acts on spring, and the bending place of spring can form the concentrated stress point, just be easy to cause fracture, if after fractureing, spring loses buckle press to rail, and rail can form horizontal play, consequence is hardly imaginable, therefore must guarantee this design gaps.Prior art is in installation process, there is no the factors such as mounting limit when while due to the construction workman, drawing spring, firmly inequality is with design, cause having the situation of installing many times all can occur, crossing to install to cause gap to reduce, the spring bending part contacts with iron chair, the stressed arc position that focuses on the spring weakness, easily cause the spring fracture.

Summary of the invention

The purpose of this utility model is exactly in order to overcome the deficiencies in the prior art, has designed a kind ofly can prevent that spring from crossing the iron chair of installation, by stopping means is set in iron chair, has guaranteed the design gaps between spring and spring mount pad.

The technical solution adopted in the utility model is, a kind ofly prevent that spring from crossing the iron chair of installation, be arranged between sleeper and rail, comprise with the plate body of bolt hole and be fixed on the spring mount pad that has through hole on the plate body both sides, key is: the spring port of export at the spring mount pad is set up positive stop.

The position of described spring mount pad on plate body is the diagonal angle setting.

Described positive stop is fixed on the ,Huo bottom, top of through hole or is enclosed in through hole.

The beneficial effects of the utility model are, simple in structure, need not change the design of existing iron chair, only increase a stopping means in the structure of existing iron chair, can solve actual very large problem, can talk about the effect of getting twice the result with half the effort, good by 3,000,000 fasteners assembling fatigue experiment, result, prove the spring performance is not affected.

1 represents plate body, and 2 represent the spring mount pad, and 3 represent positive stop, and 4 represent spring, and 5 represent sleeper, and 6 represent rail, and 7 represent resilient sleeper-bearing under rail, and 8 represent bolt, and 9 represent resilient sleeper-bearing under iron chair, and 10 represent height adjusting cushion plate.

The specific embodiment

A kind ofly prevent that spring from crossing the iron chair of installation, be arranged between sleeper 5 and rail 6, comprise with the plate body 1 of bolt hole and be fixed on the spring mount pad 2 that has through hole on plate body 1 both sides, key is: the spring port of export at spring mount pad 2 is set up positive stop 3.

The position of described spring mount pad 2 on plate body 1 is the diagonal angle setting.

Described positive stop 3 is fixed on the ,Huo bottom, top of through hole or is enclosed in through hole.

In the specific implementation, referring to Fig. 1, sleeper 5 tops are disposed with resilient sleeper-bearing 7 and rail 6 under resilient sleeper-bearing 9 under iron chair, height adjusting cushion plate 10, iron chair, rail to the utility model, and the plate body 1 in iron chair is fixed on sleeper 5 by bolt 8.Referring to Fig. 3, be provided with positive stop 3 in the through hole due to spring mount pad 2, even workman's barbarous operation in work progress, as long as design the position of positive stop 3 in through hole, can guarantee the gap between spring 4 kinks and spring mount pad 2.
