BG1330U1 - Elastic padding clamp for railway track at curves - Google Patents

Abstract

The present invention relates to the construction of a railway clamp, to be used in the maintenance and repair of railway track and in recycling of disused ferro-concrete sleepers, due to tearing thecoach screws connecting the rail to the ferro-concrete sleepers. This is elastic padding clamp for fastening railway elements, whereby on a ferro-concrete sleeper (2), steel rib pad (3) is placed andbeneath, there is elastic rubber pad (4). On the steel rib pad (3) there is a railway track (1), which in turn is pressed down by an elastic staple (5). The steel rib pad (3) has openings (6) drilledin the middle of the ribs (8) and through that holes (6) in the ferro-concrete sleeper (2), coach screws (13) are passing, coiled in plastic dowels (12), through which and through elastic staples (5)and washers (9), the rail (1) is pressed down and in turn the steel rib pad (3) is bent at its outside at an angle of not less than 30 degrees to the upper surface of the ferro-concrete sleeper (2), wherein a transverse channel (10) of triangular shape is formed.

Description

Technical field

The utility model relates to the construction of a rail fastening for use in the maintenance and repair of railways, as well as for the recycling of already obsolete reinforced concrete sleepers due to rupture of the typhoons connecting the rail to the sleepers.

BACKGROUND OF THE INVENTION

A rail fastening [1] is known, consisting of a rail rail fastened to a reinforced concrete cross member by means of a steel rib support and an elastic support. The rail is fixed to the rib cage bilaterally by two bolts, two clamping plates, two twin spring washers and two nuts. For their part, the steel rib support and the elastic support placed below it are secured to the reinforced concrete cross member by four typhoons wrapped in plastic dowels concreted in the reinforced concrete cross member and as many twin spring washers and nuts.

This fastening has insufficient reliability of the typhoon-dowel connection in the beam. In curves with a small radius, the lateral loading of the rolling stock results in a shear load of the typhoons, breaking the plastic dowels, in some cases breaking them.

Also known is the fastening of the elements of the track [2], whereby the rail is secured to the reinforced concrete cross member by means of an elastic support and two plastic angular fixing plates, installed in specially made transverse angular channels in reinforced concrete crosslinked, cross-reinforced concrete crossbar. The dowels are concreted in the beam and are equipped with flat washers and spring brackets that rest against the grooves of the angular strips and simultaneously to the rail. This fastening is of high cost and cannot be used for repair purposes.

The technical nature of the utility model

The object of the utility model is to provide such a flexible underlay fastening for fastening the elements of the track, thus making it possible to reuse defective reinforced concrete sleepers with the insertion of standard elements, which increases the reliability of the rail fastening.

The problem is solved with the help of an elastic underlay fastening for fastening the elements of the track, whereby a steel rib substrate which is bent on its outside at an angle of not less than 30 ° to the upper surface of the reinforced concrete is mounted on the reinforced concrete beam. , in which a triangular transverse channel is formed. An elastic rubber pad is placed underneath it, and a small elastic pad and a rail are mounted on the steel rib base. It, in turn, is clamped with an elastic bracket, with the steel rib support having holes drilled in the middle of the ribs through which holes pass typhoons wrapped in plastic dowels, which in turn are anchored in openings in the reinforced concrete beam.

The main advantage of the utility model is that, with the presence of a steel rib base with a curved one-sided end and an elastic support, at an angle of not less than 30 ° to the upper surface of the reinforced concrete cross member, which end is linearly parallel to the rail channel in the triangular cross-section, is achieved unilaterally in the direction of the outer side of the rail path of the steel rib lining in the cross-section. In this way, the lateral force of the rolling stock is counteracted by a linearly distributed reaction which has an application line in the contact between the forehead of the bent end of the steel rib cushion and an elastic support in the rail parallel to the rail, not in point contact between the typhoon and a hole in the steel rib lining. Another advantage of the utility model is that by forming an opening in the rib of the steel rib support and channel in the reinforced concrete beam, it becomes possible to recycle scrapped old sleepers with torn ones.

1330 Ul typhoons. With the utility model, the new typhoons are not loaded with lateral forces. The utility model, considered as technology, can be implemented not only in workshop conditions, but also on site without removing the traverse from the railway, which greatly reduces the road repair.

Explanation of the annexed figures

An exemplary embodiment of the utility model is shown in Figure 1, which depicts a sectional view of the attachment.

An example of a utility model

The elastic base rail fastening, in which a steel rib support 3 is mounted on the reinforced concrete beam 2 and an elastic support 4 is mounted below it. from the washer 9 and the elastic bracket 5. The steel rib support 3 has openings 6 drilled in the middle of the ribs 8 through which openings pass the typhoons 13, the latter being wound in plastic dowels 12 anchored in the openings 11 of the reinforced concrete trap. EPCA 2. In turn, the steel ribbed pad 3 is bent on the outer side at an angle not pomalak of 30 ° to the upper surface of the concrete sleeper 2 in which is formed a transverse groove 10 with a triangular shape. A plastic support 7 is mounted between the bent end of the reinforced concrete base and the transverse channel.

Using the utility model

A rectangular triangular channel 10 is made on the reinforced concrete defective crossbar with torn truffles. A reworked ribbed liner 3 is installed, on which in workshop conditions one end is bent at an angle of 30 °, holes 6 are drilled in the middle of the ribs 8 of the liner 3. Below these openings 6 holes are drilled 11 in the reinforced concrete beam 2, in which a plastic anchor is mounted by means of a chemical anchor 12. The large elastic support 4, the plastic support and the processed steel rib support 3 are fitted. The rail 1 is mounted on the steel rib support 3 and a small elastic support is mounted below the rail heel 1. help of the elastic brackets 5, the washers 9 and the typhoons 13 are fixed simultaneously to the rail 1 and the rib support 3. In curves with a small radius, the lateral force from the rolling stock loads the rail 1, hence the force is transmitted to the steel support 3 through the ribs to the plastic and to the plastic support. traverse. In this way the typhoons 13 remain unloaded by the lateral forces.
