Description

Description of the invention

The invention relates to the construction of railway tracks and can be used when equipping a non-contact track with fasteners 2.

There is a well-known rail fastening anchor |1), which has a shank built into the sleeper, a wall and a hook for attaching an elastic terminal that presses the rail to the sleeper. These features coincide with the essential features of the claimed invention. The anchor serves only to fasten the terminal and does not accept lateral loads on the rail.

The disadvantage of the anchor of this connection is the lack of the ability to transfer lateral loads from 70 rails to the sleeper through it.

A known rail fastening anchor |2), which has a shank built into the sleeper, a wall that limits the lateral movement of the rail, and a hook for attaching an elastic terminal that presses the rail to the sleeper. These features coincide with the features of the claimed invention. The shanks of two anchors, between the walls of which a rail is placed, are connected to each other. 12 The disadvantage of the anchor of this fastening is the large material and energy costs for its manufacture.

The complex design of the anchor allows you to make it only by casting, which is several times more expensive than cold stamping and worsens the environment.

The closest in terms of technical substance to the declared one is the rail fastening anchor |Z), which has a shank built into the sleeper, a wall that limits the lateral movement of the rail, a hook for attaching an elastic terminal that presses the rail to the sleeper, and a support on the sleeper. These features coincide with the features of the claimed invention. The hook for fastening the elastic terminal is made on the sides of the anchor in the form of two grooves with inclined surfaces.

The disadvantage of the anchor of this fastening is the large material and energy costs for its manufacture.

The complex design of the anchor with grooves and protrusions does not allow it to be made from a simple blank by cold stamping. Such an anchor can be made only by precision casting, which is several times more expensive than cold stamping and worsens the environment. Gee)

The basis of the invention is the task of providing a reduction in material and energy costs due to the manufacture of an anchor from a simple initial blank by cold stamping instead of casting.

To solve the specified problem, the rail fastening anchor, which has a shank built into the sleeper, with a wall that limits the lateral movement of the rail, a hook for attaching an elastic terminal that presses the rail to the sleeper, and a support on the sleeper made of a corner, one shelf which is a wall, and the second is a support, and the shank is made from the middle part of the second shelf, cut at the edge and bent in the direction of distance from the first shelf. The edge of the second shelf of the anchor is incised to form a flare at the end of the shank. On Ge") left after cutting, the extreme parts of the second shelf have protrusions for fixing the elastic terminal.

The wall of the anchor is made with two stiffeners formed from metal extruded from the inner part M of the first shelf.

The above-mentioned features of the proposed invention ensure the achievement of a technical result, which consists in reducing material and energy costs in the manufacture of an anchor due to the execution of an anchor from a simple /"F initial blank by cold stamping instead of casting. C 70 Making an anchor from a corner, one shelf of which is a wall, and the other a support, makes it possible to simplify the technology of manufacturing an anchor thanks to the use of a standard rolled product mastered by industry, which

"Iz" is cut into measured blanks.

Making the shank from the middle part of the second shelf, which is notched at the edge and bent in the direction away from the first shelf, allows you to reduce the cost of material and for the manufacture of the anchor, because the operation of notching and bending the shelf is performed in one stroke of the press without heating the workpiece with a minimum consumption of sh electricity. (se) Notching the second shelf with the formation of a widening on the end part of the shank makes it possible to make a widening from the flat shelf of the corner to hold the anchor in concrete with the help of an inexpensive operation of cold stamping.

Gee! 20 Extruding protrusions for fixing the elastic terminal on the extreme parts of the second shelf left after cutting allows to simplify the technology of manufacturing protrusions. The execution of the wall with two stiffening ribs, formed from metal extruded from the inner part of the first shelf, makes it possible to save metal and, with minimal costs, cut the metal and bend it in different directions in one stroke of the press. 29 A terminal can be attached to the proposed anchor, which is made in the form of a large loop covering

GF) the wall of the anchor and partially rests on the insert above the sole of the rail, with the ends bent inward.

The essence of the invention is explained by the drawings, which show: o in Fig. 1 - a general view of an anchor in a rail fastening; Fig. 2 is a top view of Fig. 1; 60 in Fig. 3 - a version of the anchor with stiffening ribs at the wall in a rail connection with a terminal made in the form of a large loop that covers the wall of the anchor; Fig. 4 is a general view of an anchor with a hole cut in the wall; in Fig. 5 - a view from the left in Fig. 4; Fig. 6 is a top view of Fig. 4; because in Fig. 7 - a general view of an anchor with stiffening ribs near the wall;

in Fig. 8 - a view from the left in Fig. 7; Fig. 9 is a top view of Fig. 7.

Rail fastening anchor 1 has a shank 2 built into the sleeper 3, a wall 4 that limits the lateral movement of the rail 5, a catch b for attaching the elastic terminal 7 that presses the rail 5 to the sleeper 3, and a support 8 on the sleeper 3. The anchor is made of corner 9, one shelf 10 of which is a wall 4, and the second shelf 11 is a support 8.

Shank 2 is made from the middle part of the second shelf 11. This shelf is notched at the edge 12 and bent in the direction away from the first shelf 10. The edge 12 of the second anchor shelf is notched to form a widening 13 on the end part of the shank 2. Moreover, the notch of the edge 12 of the second shelf 11 can be performed on a part of its /0 width or along the entire width, as in the second version of the anchor 14. In the second case, the shank 2 has a greater widening 13 to prevent the anchor from being pulled out of the sleeper 3. However, the material consumption increases because the shelf must have a longer length.

On the extreme parts of the second shelf 11 left after cutting, projections 15 are pressed out for fixing the elastic terminal 7 in the working position. The wall 4 of the anchor 1 can be made with a cut-out hole for the terminal or with /5 two stiffening ribs 16 formed from metal extruded from the inner part of the first shelf 10 of the anchor 14.

Stiffeners 16 must touch with their lower surfaces 17 the support 8 in order to transfer to it the load forces of the wall with the sole of the rail 5. It is possible to weld the surface 17 with the support 8. The internal, turned towards each other surfaces 18 of the stiffeners 16 can serve as guides for the end sections 19 Terminals in the case of its execution in the form of a large loop 20 covering the anchor 14.

After embedding the anchors 1 with the shanks 2 in the concrete sleeper Z with a given distance between their walls 4 and with the supports 8 touching the concrete surface, a rubber insulating gasket 21 is laid in the space between the vertical surfaces of the anchors 1. A rail 5 is placed on the gasket 21, between the edges of the sole of which and the walls insulating liners 22 are laid on the 4 anchors, which transmit the lateral force from the side of the rail 5 to the walls of the 4 anchors 1. On top of the anchors 1, rod elastic terminals 7 are laid so that the terminal 23 is located on top of the liner 22 in sections. Then, with the help of a lever tool, the terminals 7 are pushed onto the rail 5. Their middle sections 24 i) enter the catch 6, and the sections 25 lean into the protrusions 15. The rail 5 is securely pressed against the sleeper 3.

In the process of fastening, the anchor 1 perceives lateral horizontal forces from the sole of the rail 5 and vertical forces from the loaded elastic terminal 7. The anchor made of a rolled corner has high strength and plasticity, it has no porosity, which is possible in casting. The cost of the proposed anchor, made by cold stamping from a rolled corner, in mass production is about two times lower than the cost of an anchor made by casting. co
