UA77059C2 - Fixation of rails to tie - Google Patents

Abstract

The rail fixation to tie has springy sockets that through its insulator rest with pressing section on the base of the rail. In the concrete tie anchor block is fixed, its head is arranged with slots for fixation of the ends of the springy socket. Theanchor insulator is fixed on the ribs of the head of the anchor block. For possibility of automation of the process of mounting-dismantling the sockets in the head of the anchors are made shaped. The upper surface of slots is formed with two pairs of planes inclined one towards another at angle =140...170 DEGREE . At that the plane of each of the pair of planes placed nearer to the base of the rail is made descending, and the adjoining it - ascending.

Description

Description of the invention

The presented invention relates to the construction of the railway, namely, to the elements of the upper structure of the track. 2 The previous inventions of the TRANSROAD GROUP company in the development of spring fastenings of the upper structure of the track (patents: ОАМо51726; ШОАМо54572 and ОАМо72618| have passed many years of successful tests on the railway near Moscow, representing cheap and reliable fasteners of the rail to the sleeper.

Spring terminals can be inserted into slots in the anchor head next to the rail by hand, using a sledgehammer to drive the terminal into the slots, or mechanically using a lever device. But if it is necessary to significantly reduce the time of disassembly and installation of fasteners when replacing rails in the field, in order not to stop the movement of trains, there is a need for automated installation of the terminal, as a faster and labor-intensive process, but which can be arbitrarily multiphase, requiring accurate positioning of the terminal relative to the anchor , in order to achieve an adequate fastening of the rail.

The invention is based on the task of fastening the rails to the sleeper by changing the configuration of the head 72 of the anchor node and using separate insulators for the terminal and the anchor to ensure a complete factory assembly of the fastener with a reinforced concrete sleeper and the ability to automate the process of installing and disassembling the terminal in the field.

The technical result consists in changing the design of the anchor head to ensure additional fixing of the terminal in the "parking" position and the condition of the factory assembly of the fastener. Achieving them in the fastening, which includes an elastic terminal, which through its insulator rests with the pressure part on the sole of the rail, and an anchor node fixed in a concrete sleeper, the head of which is made with grooves for fixing the ends of the elastic terminal in the "parking" and working positions and recesses and ribs for fixing the anchor insulator.

The cause-and-effect relationship between the set of features of the invention and the technical result is that the upper plane of the grooves of the head is formed by two pairs of adjacent planes inclined to each other at an angle a in the range of 145-1762, one of which is located closer to the sole rails - placed bent upwards under (9 angle D-15...202) the end of the elastic terminal in the "working" position and in the "parking" position on adjacent planes distant from the sole of the rail. A rectangular recess is made on the upper surface of the anchor head, and on the side on the sides from the side of the sole of the rail, two ribs are placed for fixing the anchor insulator. The invention is illustrated by drawings, where: Ф

In Fig. 1, 2 and C, the rail is marked with position 1, position 2 is the sole of the rail, position Z is an elastic gasket, position 4 is a reinforced concrete sleeper, position 5 is an anchor node (Figs. 7 and 8), the head 6 of which is made of shaped grooves 7, the upper surface of which is formed by a pair of planes inclined to each other at an angle o, 140-170 of two planes 8 and 9 and 10 and 11 for fixing the elastic terminal 12. On the upper surface 13 of the head 6 of the anchor node 5 is formed from the side rails 1 rectangular recess 14 in which the anchor insulator 15 (Fig. 9, 10) is fixed by -1 with the help of a protrusion - 16, and on the side surfaces of the head 6 of the anchor assembly 5 are placed on the side of the sole 2 of rails 1 two ribs 17 on which with the help anchor insulator 15 is fixed in blind grooves 18. Two ribs 17 and head b significantly increase the contact plane with anchor insulator 15, extending its service life. The anchor insulator 15 with its lower plane 19 presses and holds the elastic spacer C (Figs. 1 and 3). The elastic terminal 12 (Fig. 4) is made of a solid rod 216bmm with bent inward terminals parallel to the parts 20, the ends of which are bent in the form of catches 21, opposite to which there is a pressing part 22, which

Ge; connected to the parts 20 by two inclined straight lines 23 and two half-rings 24. A terminal insulator 25 (Fig. b) is put on the pressing part 22 of the terminal 12.

The fastening of the rail to the reinforced concrete sleeper is mounted in the factory as follows: on the reinforced concrete vv sleeper 4, between the heads b of the anchor nodes 5 (Fig. 3), an elastic spacer C is placed, which is pressed by two anchor insulators 15, putting them on the ribs 17 of the anchor node 5 until until the projection 16 sits in (F) the rectangular recess 14, then the terminal 12 with the terminal insulator fitted to the pressure part 22

The GI is wound in parallel parts 20 into the shaped grooves 7 of the head 6, while the pressing part 22 with the terminal insulator 25 is placed on the upper surface 13 of the head 6. Then the terminal 12 is moved with the help of the device towards the rail 1 to the "parking" position, where the hooks 21 planes 10 and 11 reliably fix the terminal 12 in the "parking" position, while the pressing part 22 with the terminal insulator 25 runs, creating the necessary tension of the terminal 12, on the protrusion 16 of the anchor insulator 15 and fixes it on the ribs 17 of the anchor assembly 5, and the anchor insulator 15, the lower plane 19 holds the elastic gasket 3.

The sleepers with mounted fasteners (Fig. 3) are ready to be sent to the railway tracks, where they are placed on 65 prepared ballast, then rails are laid between the anchor insulators, and after leveling the track, an automated cart on which the operator sits is launched along it.

A lifting traverse with two pairs of drive grippers-pushers is mounted on the trolley 12. The trolley drives the traverse onto the sleeper, the sleeper catcher is activated and the traverse lowers the grippers onto all four terminals of the sleeper, the hydraulic drive of the pushers grippers is activated, which move terminals 12 into the working position, i.e. the pressing part 22 with the terminal insulator 25 hits the sole of the rail 2 and the anchor insulator 15, pressing them with the necessary force to the reinforced concrete sleeper 4 through the elastic gasket Z, while the catches 21 fix the terminal 12 on planes 8 and 9. The operator lifts the traverse and moves to the trolley to the next sleeper, where everything is repeated.

To replace worn rails, it is necessary to replace the drive grippers-pushers with others that drag the terminals from the 70 working position back to the "parking" position, releasing the entire sleeper from the fastening, which allows you to quickly replace the rails in the interval between the trains.

In the same way, the fastening allows you to quickly replace worn elastic gaskets 3, terminal insulators 25, anchor insulators 15 and adjust the height of the rail in winter.
