Description

The invention relates to the design of the superstructure of a railway track, in particular to intermediate rail fastenings, and is intended for attaching a metal lining to a sleeper with a removable element for fixing a device for attaching the lining to the sleeper.

A rail clamp-bolt fastening on a reinforced concrete base is known, in which a metal lining is installed on the sleeper by means of a device for fastening the lining to the sleeper, containing two embedded bolts with nuts (see patent RU 2112823 U1, MPK7 E01B 9/02 (1995.01), 09.06. 1997).

In the known rail terminal-bolt fastening, the necessary maintainability of the main operating tracks is not ensured, due to the high corrosion of the nut and bolt of the embedded bolt, and requires sawing off the nuts of the embedded bolts during repairs.

The closest to the proposed invention in terms of the totality of essential features is a butt and separate intermediate fastening of the KB65 type on reinforced concrete sleepers with P65 and P75 rails, including a device for fastening the lining to the sleeper, containing fasteners for rail fastenings of the railway track, installed with the possibility of rotation in the groove of the sleeper and on which the fastening elements are placed (see Fastenings for reinforced concrete sleepers, Fig. 3.9., Internet site https://studref.com/439369/tehnika/skrepleniya_zhelezobetonnyh_shpal#64).

This device for fastening the lining to the sleeper does not provide the necessary maintainability of the main operating tracks, due to the high corrosion of fasteners - nuts and embedded bolts, which requires sawing off the nuts of embedded bolts during repairs.

The objective of the present invention is to create a device for attaching a lining to a sleeper, ensuring the necessary maintainability of main operating tracks.

The technical result when using the proposed invention is to increase the maintainability of main operating tracks, due to the simplicity and convenience of disassembling and assembling the device.

The specified technical result is achieved in that the device for fastening the lining to the sleeper, containing fasteners for rail fastenings of the railway track, installed with the possibility of rotation in the grooves of the sleeper and on which the fasteners are located, is equipped with fixing elements of the device for attaching the lining to the sleeper, and the fasteners made in the form of screws, at one end of which there are fastening elements of the device for attaching the lining to the sleeper with the possibility of rotation in the grooves of the sleeper and movement relative to the axis of the screws, while the fixing elements of the device for attaching the lining to the sleeper are made of polymer material with a threaded through hole and a header for centering the screw and preventing it from turning in the grooves of the sleeper, made in the form of a parallelepiped, while the fixing element of the device for attaching the lining is installed with the possibility of removal from the end of the screw.

It is also preferable that the headrest is made with rounded corners, on the side surfaces of which there are cylinders, and inside the headrest and both cylinders there is a through hole with a thread located along the central axis.

The invention is illustrated by drawings.

In fig. 1 shows a device for attaching a lining to a sleeper in a rail fastening, general view;

in fig. Figure 2 shows the fixing element of the device for attaching the lining to the sleeper, general view.

A device for fastening a lining to a sleeper of an intermediate rail fastening is intended for fastening a metal lining to a reinforced concrete sleeper.

The rail fastening consists of a metal lining 1, which is installed on both sides of the rail 2 in the sleeper 3 and secured by a device for fastening the lining to the sleeper, containing screws 4, on which insulating bushings 5, brackets 6 and washers 7 are located in the upper part, and on the lower part At the ends of the screws, there are removably installed elements 8 for fixing the device for attaching the metal lining 1 to the sleeper 3.

Rail 2 is fixed to the metal lining 1 with terminals 9 using clamp bolts 10, double-turn washers 11 and nuts 12. Between the sleeper 3 and the metal lining 1 there is a sleeper spacer 13, and between the rail 2 and the metal lining 1 there is an under-rail spacer 14.

Each element 8 of fixing the device for attaching the metal lining 2 to the reinforced concrete sleeper 3 contains a header 15 for centering the device for attaching the lining to the sleeper and preventing it from turning, and the fixing element 8 of the device for attaching the lining to the sleeper is installed with the ability to rotate and move relative to the axis of the screw 4.

The fixing element 8 of the device for attaching the lining to the sleeper is made of a polymer material, while the header 15 of the element 8 is made in the form of a parallelepiped with rounded corners, on the side surfaces of which cylinders 16 and 17 are located, and inside the header 15 and both cylinders 16 and 17 a through hole 18 with thread, located along the central axis.

The presence and implementation of element 8 for fixing the device for attaching a metal lining made of polymer material makes it possible to increase the maintainability of the intermediate rail fastening, because High corrosion of fasteners - nuts and embedded bolts, which requires sawing off the nuts of embedded bolts during repairs, is excluded.

Making the header 15 of element 8 in the form of a parallelepiped allows you to easily install the screw 4 into the groove of the sleeper 3 to center the device for attaching the lining to the sleeper and prevent it from turning, which makes it possible to increase the maintainability of the intermediate rail fastening.

Making the fastener in the form of a screw 4 increases the maintainability of main operating tracks, because there is no corrosion of the fastening elements - nuts and bolts of the embedded bolts and there is no need to cut off the nuts of the embedded bolts during repairs.

The presence of element 8 allows not only to increase the maintainability of main operating tracks, but also to simplify their maintenance, because There is no need to constantly tighten the nuts of the mounting bolts.

The device for attaching the lining to the sleeper operates as follows.

For each screw 4, the fixation element 8 is manually screwed one turn so that the thread of the screw 4 coincides with the thread of the fixation element 8. To take the mounting position, the fixing element 8 is installed in the groove of the sleeper 3 and rotated 90° clockwise. After the fixation element 8 has assumed the mounting position, the screw 4 is finally tightened to the specified value.

When carrying out repairs to replace one screw 4 or two screws 4 at the same time, the sequence of operations is repeated.

When using the claimed invention, each distinctive essential feature of the invention formula affects the achievement of the technical result, because the cause-and-effect relationship between the technical result and the set of distinctive essential features of the invention is identified and described.

The presence of distinctive essential features of the invention in the technical solution makes it possible to achieve, when used, the stated technical result: increasing the maintainability of main operating tracks, due to the simplicity and convenience of disassembling and assembling the device.
