Product Optimization

I-type adjusted fasteners were improved on the basis of clip type I fasteners.

Product Description

The spring clip type I height adjustment fastener is a shoulder type, suitable for 60kg/m rails. It is improved on the basis of spring clip type I fasteners, the gauge baffle is raised, and a height adjustment pad is added. The height adjustment amount is increased from 10mm of spring clip type I fasteners to 20mm. In concrete bridge sleepers or integral roadbed sections, the rail top elevation can be adjusted with the rail height adjustment pad.

Fastener Parts:

The clip type I adjusted fastener consists of type I spring clips, gauge baffles, baffle seats, rubber pads, height adjustment pads and spiral spikes. Its structure is the same as that of ordinary clip type I fasteners. The difference is that its height adjustment amount is 20mm, while that of ordinary spring clip type I is 8-10mm. In order to achieve this height adjustment amount, the gauge baffle and baffle seat have been improved structurally to maintain a good ability to buckle the rails.

Scope Of Application And Technical Support:

The spring clip type I adjusted fastener is only applicable to 60kg/m rails, and the spring clip is type A. The spring clip type I height adjustment fastener is similar to the spring clip type I height adjustment fastener. The spring clips are divided into middle spring clips, joint spring clips and reinforcement spring clips. It is suitable for 50 and 43kg/m rail concrete sleeper lines, where it is inconvenient to carry out tamping operations and the rail height adjustment gaskets are required to make large adjustments to the rail level. The maximum height adjustment is 25mm.

Features & Advantages

The follow are features and advantages of type I rail fastening system.

Structure Features:

1) The spring bars of the I-type fastener system are divided into two types, A and B;
2) Among them, the A-type spring bar is longer and is used on 50 and 60kg/m rails. The track baffles for 50kg/m rails are divided into two types, middle and joint, each with two numbers 14 and 20. For 50kg/m rails, except for the 14th joint gauge baffle, the rest are installed with A-type spring bars;
3) There is only one type of gauge baffle for 60kg/m rails, with two numbers 6 and 10, both of which are installed with B-type spring bars;
4) The buckle pressure of a single spring bar of the A-type spring bar is 8 kN, and the spring range is 9 mm. The buckle pressure of a single spring bar of the B-type spring bar is 9 kN, and the spring range is 8 mm. The static stiffness of the rubber pad under the rail is 90-120 kN/mm;
5) Due to the high buckle pressure, the use of spring bar I-type fasteners does not require the installation of rail anti-climbing equipment, and the line is stable. It is still widely used in railways.

Advantages Of Type I Rail Fastening System:

1) Compact structure, high buckling pressure on railway sleepers;
2) Adjustable gauge;
3) Contains relatively few parts;
4) Low maintenance workload;
5) Used on straight or curved tracks of standard gauge (radius not less than 300 meters);
6) Elastic I-type rail fasteners have good elasticity, small pressure loss, and can better maintain the geometric shape of the rail track;
7) Suitable for standard gauge railway straight lines and curved sections with a radius of ≥ 300 mm, connected with 50 kg/m and 60 kg/m rails.
