Description

The invention relates to the field of railway construction, namely to the details of rail fastening and describes a device designed to transfer the lateral load from the rail to the anchor fastening device of the rail clamp.

The prior art known solutions.

Known side insulator rail fasteners (RF patent No. 129938, published 07/10/2013), consisting of a first plate, a second plate protruding perpendicularly from the central part of the upper edge of the first plate, and at each end of the first plate there are protruding upwardly positioning insulator elements that extend perpendicular to the first plate, with the positioning elements of the insulator spaced from the second plate, each of the positioning elements in the lower surface has a groove extending parallel The first plate, the positioning supports extending from the lower surface of each positioning element of the insulator, remote from the first plate and having an inclined upper surface, and walls connecting one side of the upper surface of the positioning supports to the positioning elements of the insulator.

Also known side insulator rail fasteners (RF patent №181212, published 06/07/2018), consisting of a first plate, a second plate protruding perpendicularly from the central part of the upper edge of the first plate, with the first plate lower in its central part than at the ends, on each end of the first plate has upward protruding positioning elements of the insulator, which extend perpendicular to the first plate, with the positioning elements of the insulator spaced from the second plate, each of which positioning their elements in the lower surface has a groove extending parallel to the first plate.

The closest analogue of the patented solution is the side rail binder insulator (RF patent №2436885, published 11/20/2011), consisting of the first and second elements interconnected by means of two links. The first element consists of a vertical support face with a notch in the middle, in which there is a protrusion facing the second element. The second element consists of two spaced apart seats for the clamp, connected by an elongated link. The clamp seats have corresponding L-shaped receiving surfaces under the clamp. In the rear ends of each surface there is a recess. The elongated links and seats under the clamp are hollow elements, reinforced with edges if necessary.

A disadvantage of the known solution lies in the insufficient rigidity of the edge due to the interrupted structure, which is structurally necessary for receiving the clamp.

The technical problem is the need to increase the rigidity of the support face, since it is the main side load from the rail that falls on it. In a known solution, the cut has a protrusion, however, it is a shelf, the edges of which are located at some distance from the edges of the cut.

The problem is solved by modifying the shape of the reference face.

The technical result of the patented solution is to increase the strength of the side insulator by increasing the rigidity of the support face, which receives and redistributes the main load when interacting with the rail.

The claimed technical result is achieved due to the design of the side insulator of a rail fastening consisting of a supporting front face and a seating face interconnected by hollow rods, while the supporting face has a cutout in the lower part of which there is a protrusion beyond the inner surface of the supporting face, the protrusion being equal to the length of the cut, and the junctions of the bottom of the cut and its side walls are rounded.

In the particular case of the implementation of the utility model, the landing face has two protruding L-shaped profiles with recesses on the upper surface, interconnected by a hollow rod.

In the particular case of the implementation of the utility model, the lateral insulator is made of PA 66 - polyamide.

  Making the walls rounded provides a redistribution of the load inside the notch of the support face by eliminating the stress concentration at the junction of the side walls of the notch and its bottom. The protrusion in the lower part of the notch together with stiffening ribs placed under the protrusion, due to the fact that its length is equal to the length of the notch itself, is essentially a continuation of the notch and creates an additional stiffening rib of the support face.

Further, the solution is explained by reference to the figures, which show the following.

FIG. 2 is a general view of the side insulator of the rail fastening below.

FIG. 9 is a side insulator of rail fastening in section A-A from FIG. eight.

FIG. 10 is a side insulator of a rail fastening in section B-B from FIG. eight.

The side insulator consists of a supporting front face 1 and a landing rear face 2, interconnected by rods 3 with a cellular structure. At the same time, the rods 3 have at least two cells 13. The cellular structure increases the rigidity of the insulator and prevents lateral deformation of the structure during lateral loads received by the rail fastening unit from the rail as the train moves.

Supporting edge 1 has a notch 4, on both sides of which there are profile protrusions 12. These projections due to their profile structure have the ability to fit snugly to the front walls of the rail fastening anchor, isolating them from the rail, and also to perceive lateral loads from the rail and transfer them on the anchor.

In the lower part of the notch 4 there is a protrusion 5 protruding beyond the inner surface of the support face 1. The length of the protrusion 5 is equal to the length of the notch 4, and the joints 6 of the lower part of the notch and its side walls are rounded. The protrusion is a continuation of the vertical support face 1 and overlaps part of the anchor.

Under the protrusion there are transverse stiffening ribs 11, abutting against the inner surface of the front face 1 and the lower surface of the protrusion 5. These ribs are placed preferably with equal pitch relative to each other and can include from 2 to 10 ribs.

The second facet 2 - landing - has two protruding L-shaped profiles 7 with recesses 8 on the upper surface, interconnected by a rod 9 with a cellular structure comprising at least three cells 10. The L-shaped profiles 7 also have a cellular structure.

The side insulator is made of PA 66 - polyamide.

The proposed utility model is used as follows.

The cutout formed in the rear support edge between the profiles 7, interacts with the protrusion of the insulating platform of the rail fastening anchor, and the front edge interacts with the front wall of the upper part of the anchor on the one side and with the lateral surface of the rail foot, with the projection 4 partially overlapping the front wall of the anchor and takes part of the load from the terminal, fixed in the clamping insulator between the side walls of the anchor.
