Abstract
An elastic fastener for a railroad switch includes an elastic strip, a release bar and a railroad distance regulation bloc; wherein, the elastic trip is a U-shape strip with a protruded middle part; the release bar is also U-shaped, whose rear arch fits close to an arch bloc of a metal liner plate; a positioning bloc on the side plane of the release bar is arranged on the railroad distance regulation bloc; the two inner sides of the railroad distance regulation bloc match the bottom of the railroad. The improved elastic fastener for the railroad switch is reasonable in design and reliable in performance, which is in compliant with the technological regulations. The fasteners are characterized by a simple structure, excellent elastic performance and less steel required. In installation, the fasteners can match the original metal liner plate, which greatly cuts down manufacturing cost. After satisfactorily regulated, the device can keep safe operation of trains and satisfy the demand for improving speed of the trains. The improved elastic fasteners can be promoted and utilized in recycled railroad switches.
Description
(1) technical field
The utility model belongs to the railway switch fastener, is specifically related to a kind of railway switch elastic bar fastener.
(2) background technology
Before 1998, the fastener that uses on the railway switch all is to adopt pinch plate rail fastenings such as 63 types, 67 types, 70 types.Deficiencies such as this pinch plate rail fastening exists that rigidity is big, poor flexibility, rolled steel dosage are big, after using after a while, fastener is loosening easily on the line, and buckle press reduces, and can not satisfy the requirement of railway speed increase.The Ministry of Railways requires when using the track switch overhaul again, needs pinch plate rail fastening all is replaced by elastic bar fastener, and one group of track switch needs 100,000 yuan, and expense is higher, has increased the expense expenditure of basic-level stations and depots greatly.
Elastic bar fastener good springiness, buckle press are big, and spring is made up of the arc of three sections bendings, sees accompanying drawing 5.Use this elastic bar fastener to match with the iron chair of straight line blend stop, the iron chair of original pinch plate rail fastening band arc blend stop is all discarded, loses bigger.
(3) summary of the invention
The utility model will have pinch plate rail fastening now and be improved to elastic bar fastener, buckle after the improvement can mate with the iron chair of original band arc blend stop, spring is simple in structure, be easy to processing, satisfying the technical stipulation requirement, guaranteeing under the prerequisite of traffic safety, can reduce production costs minimizing expense expenditure greatly.
Technical solution of the present utility model is: the railway switch elastic bar fastener is made up of spring, buckle, gauge adjusting block.The spring profile is a U-shaped, two limbs middle part protuberance; The buckle profile is the shape of a hoof, and the middle part is processed with the concave surface of placing the U-shaped spring, and the center is provided with bolt hole, and the concave surface of placing spring is provided with the spring block, and the side plane of buckle is provided with locating piece; Inboard both sides of gauge adjusting block and flange of rail coupling, the upper and lower open slot that is provided with of gauge adjusting block, open slot cooperates with the buckle locating piece.
During installation, earlier shape of a hoof buckle is placed on the iron chair, buckle rear end cambered surface and iron chair arc blend stop are closely connected, again gauge adjusting block is installed on the locating piece of buckle side plane, the gauge adjusting block inboard is pressed in flange of rail portion, and then the U-shaped spring is placed on the buckle concave surface, and the spring crowning up, two outlimbs are pressed in above the gauge adjusting block, and are by T shape dormant bolt that buckle, spring and iron chair is fastening.
Railway switch elastic bar fastener after the improvement, reasonable in design, dependable performance meets the technical stipulation requirement.Fastener structures is simple, good springiness, and rolled steel dosage is few, can mate with original iron chair during installation, cost of production significantly reduces, and is respond well through on-the-spot Installation and Debugging, can guarantee traffic safety and satisfy the requirement of railway speed increase that the modified elastic bar fastener can be promoted the use of on again with track switch at railway.

Wherein: 1, T shape dormant bolt 2, nut 3, plain washer 4, spring 5, buckle 6, gauge adjusting block 7, iron chair 8, iron chair blend stop 9, spring block 10, locating piece
(5) specific embodiment
As shown in Figure 1 and Figure 2, the railway switch elastic bar fastener is made up of spring 4, buckle 5, gauge adjusting block 6.During installation, buckle is placed on the iron chair 7, and its rear end cambered surface and iron chair arc blend stop 8 closely connected location are fixed together buckle 5, spring 4, gauge adjusting block 6 by T shape dormant bolt 1, nut 2, plain washer 3 with iron chair 7.
U-shaped spring 4 adopts 60Si
2The Mn hot rolling spring steel is made, spring two limbs middle part protuberance, and under the situation of bearing 1200～1600 kilograms of pressure for a long time, maintenance elasticity that can be permanent is with rail and fastener forcing together tightly.
Through on-the-spot installation testing, technical data is as follows:
Buckle press 〉=10KN during the fastener assembling
Single-piece spring moment of torsion: 110-130Nm
Single-piece spring maximum stress: 1200Mpa
Adjust piece error ± 0.3mm
Gauge adjusting range ± 15mm
The utility model can guarantee traffic safety fully and satisfy the requirement of railway speed increase, can promote the use of on again with track switch at railway.
Claims (2)
1, a kind of railway switch elastic bar fastener is made up of spring, buckle, gauge adjusting block, it is characterized in that the spring profile is a U-shaped, two limbs middle part protuberance; The buckle profile is the shape of a hoof, and the middle part is processed with the concave surface of placing the U-shaped spring, and the center is provided with bolt hole, and the concave surface of placing spring is provided with the spring block, and the side plane of buckle is provided with locating piece; Inboard both sides of gauge adjusting block and flange of rail coupling, the upper and lower open slot that is provided with of gauge adjusting block, open slot cooperates with the buckle locating piece.
