Description

The utility model relates to railway transport, namely to traveling machines designed to control, measure and straighten a railway track and can be used to identify the true state of the track with respect to a given state during repair and maintenance of railways.

To increase the efficiency of work in the construction, repair and operation of Russian railways, it is necessary to implement advanced highly economical technologies, which in turn requires the creation of new generation machines.

An analysis of technological processes for the reconstruction of railways, based on the best practices of leading European countries (Austria, Germany, France, etc.), shows that for the implementation of highly economical technologies in the reconstruction and repair of railways, they should be based on high-performance new generation machines capable of one technological window to monitor and measure the parameters of the railway track, as well as carry out its alignment.

A number of track machines are known, both domestic and foreign, described in the technical and patent literature. However, some of them are designed to control a single parameter, for example, the straightness of the rail [see author testimonial. USSR No. 1470828, class ЕВВ 35/00, publ. 1989], the distance between the rails [see author testimonial. USSR No. 1641922, class ЕВВ 35/00, publ. 1991]. Other machines control a whole range of parameters, for example, a well-known machine [see author testimonial. USSR No. 1671756, class ЕВВ 35/00, publ. 1991] is intended for

control deviation of rail tracks in a longitudinal profile, plan or level. Also known is a device that is designed to determine the spatial position of the rail track [see RF patent 2026448, cl. ЕВВ 35/00, publ. 1995], a device designed to detect irregularities on the rolling surface of a rail [see RF patent 2035534, cl. ЕВВ 35/00, В61К 9/08, publ. 1995]. Thus, a common drawback of the above analogues is the limited functionality.

As an analogue of the proposed utility model, one can also consider a new generation machine developed by the Austrian company Plasser and Teurer, [see RF patent 2041308, cl. ЕВВ 29/04, 27/17, publ. 1995], patented in Russia in 1992. The machine is designed to straighten the railway track and consists of a frame supported by running trolleys, travel drive, motor and driver's cab. In the area of the rear end of the machine there is a lifting and leveling unit driven by the drives, which can be moved in height and in the lateral direction. In front of the lifting-leveling unit, two jacks are installed, which serve to support the machine on the base of the track. Behind the lifting and leveling unit there is a measuring trolley with a reflector to reflect the reference light beam emitted by the IR transmitter. In the driver's cab is the central control unit (CBU) and the operator's seat. On the straightened section of the track located behind the machine, there is a theodolite with an infrared transmitter or receiver and distance meter. Theodolite is connected to a computer and a central computer. Thus, the known machine is equipped with modern measuring equipment and is a new generation machine. However, it only carries out the alignment of the railway, which must be preceded by complex and expensive work to measure and evaluate the true condition of the track. These works are carried out during a measuring trip on a special measuring machine, which is essential

a disadvantage of the known machine, which does not allow straightening the railway track in one window.

The closest in its technical essence to the proposed utility model is a machine on the rail, designed to measure, register and adjust the position of the track [see RF patent 1505447, cl. EB01 35/04, publ. 1989]. The machine selected as a prototype consists of a track-measuring car and a trolley, which in the transport position is located on the site of the front section of the car. Entrance of the truck to the site is carried out on the rails of the platform, mating with the rails of the car and the rails of the railway track. Tracking car contains a central drive and power supply unit, travel drive, as well as a wiring closet with electronics and a recording device or computer. A laser receiver, track measuring reference systems for measuring the position of the rails in the plan and profile for interacting with fixed points located outside the track, namely, on the masts of the contact network, are mounted on the cart. An additional laser emitter and a laser receiver are also installed on the trolley. The trolley can be made with an operator's cab to control a device for measuring the position of the path in plan and height. A well-known track machine has an important advantage, which consists in the fact that without a preliminary measuring trip it allows you to measure deviations of the true position of the track in relation to the design. However, it should be noted a number of disadvantages, of which the most important are:

- the inability to automatically identify the site (only visual identification of the site of work by the operator);

- the inability to automatically determine the location of the machine on the site, to compare the actual position of the track in space with its reference position;

- the impossibility without the participation of the operator to determine or select from the on-board computer database the reference characteristics of the site;

- changing the reference characteristics of the section (for example, when increasing the speed of trains) requires changes to the database on all on-board computers of all track machines that can be used for repairs on the changed section.

These disadvantages significantly limit the functionality of the machine.

The objective of the proposed utility model is to expand the functionality of the device while increasing productivity, rational operation of equipment, as well as high quality of work.

To achieve this technical result, a track machine is proposed, which, like the one closest to it, selected as a prototype, contains a frame supported by running trolleys, equipped with any replaceable equipment, for example, straightening, straightening, ballasting, finishing, and others. The track machine is equipped a control and measuring system consisting of sensors measuring the position of points of the railway track relative to each other, the position of the contact network, the state of the rail and other characteristics of the track, and the on-board computer that stores information from the sensors.

A feature of the proposed utility model that distinguishes it from the well-known track machine adopted as a prototype is that the track machine additionally has a radio frequency identification transceiver (reader) with an antenna connected to the on-board computer, and radio frequency tags are installed on the railway track ( tags) that store reference information about the parameters of the railway track. Radio frequency tags (tags) are installed either in the earthen

the canvas under the rail-sleeper grid, or they can be mounted directly on the railway sleepers.

The technical result achieved in the proposed utility model is obtained by equipping any track machine (straightening straightening, ballasting, finishing, etc.) with a radio frequency identification transceiver (reader) with an antenna and installation of radio frequency tags (tags) on the railway track, which store reference information about the parameters of the railway track. These newly introduced features significantly expand the functionality of the track machine, selected as a prototype, providing storage of all information about the condition of the track (design parameters and deviations from them, the name of the section and station, laying temperature, contact network parameters) directly on the railway track in radio frequency tags (tags). Now all the information collected by track cars is stored directly on the track and transmitted to any straightening and repair equipment at any time and without operator intervention. The transmission of information about the reference characteristics of the track, unlike the prototype, is carried out not via information networks, not via floppy disks or any intermediate devices, but directly through the railway. This, in turn, allows you to straighten the path for one window without a measuring trip, carry out finishing work, etc. At the same time, the machine is positioned on the path automatically, while in the prototype the operator manually enters the start point of the measured section, guided by special marks on the sleepers , special picket posts or supports of the contact network. As a result, with an increase in the productivity of work, the rational use of equipment, the quality of the work performed also increases.

It should also be noted that the information in the RF tags (tags) can be supplemented and changed, and the data on the RF tag can be classified. Labels are durable, inexpensive, and reliably protected from environmental influences.

Thus, the combination of the above features allows us to solve the tasks.

Two specific examples of the implementation of the proposed utility model are described below, in accordance with paragraphs 2 and 3 of the patent claims.

The proposed utility model is illustrated by drawings, which depict:

figure 1 - the proposed track machine (General view);

figure 2 is a diagram of a first example implementation of the proposed utility model, illustrating the use of radio frequency tags (tags) as permanent path devices;

figure 3 presents a diagram of a second example of implementation of the proposed utility model, illustrating the use of radio-frequency tags (tags) as temporary devices of the path;

figure 4 is a diagram of the installation of an RFID tag (tag) on a wooden sleeper.

Tracking machine consists (see Fig. 1) of frame 1, supported by running trolleys 2. In these specific examples, straightening and leveling equipment 3 is installed on frame 1. Tracking machine is equipped with a control and measuring system 4 consisting of sensors 5. In the cab 6, the operator has an on-board computer 7 that stores and processes real-time information from the control and measuring system 4 and sensors 5. On the track machine above the railway 8, a radio frequency identification transceiver 9 is installed (read ) From the transmission-reception antenna 10, coupled to cable (Fig. Not shown) with the onboard computer 7. The RF tags 11 (tags) can be installed in the roadbed 12 under-rail plank

lattice (see figure 2), or can be fixed on the sleepers 13 of the railway track (see figure 3).

As the transceiver 9 can be used, for example, readers operating at frequencies of 868 MHz, with a detection range of more than 100 m, with an identification frequency of 100 times per second, with a memory size of 32 kB rewritable tag, for example, readers of the Austrian company Baumer Ident. As radio frequency tags 11, for example, tags DT.AO.F1.xx-x of the same company can be used.

The installation of the transceiver 9 (reader) and RF tags 11 (tags) is as follows.

On railway straightening machines (VPR (s) and track cars, a radio frequency identification transceiver 9 (reader) and a transceiver antenna 10 are installed. Installation is carried out on the floor of the track machine frame 1 from the bottom.

When using RF tags 11 (tags) as permanent path devices, they are installed in the subgrade 12 under the rail-sleeper grid at a depth of 1 m from the surface (see figure 2). This arrangement of radio frequency tags 11 (tags) is due to the fact that if they are located on the surface, they can be damaged during repairs on the way by mechanisms, people, or be stolen.

In the case of using radio-frequency tags 11 (tags) as temporary track devices, for example, during the production of major or medium track repairs, their installation is carried out on the sleepers 13 of the railway track (see figure 3). The radio frequency tag 11 (tag) is located at the point of commencement of work. For wooden sleepers 13, a plastic gasket 14 is installed on its surface, which is attached to the sleepers 13 with two screws 15 through holes 16 (see figure 4). Gaskets 14 are glued to reinforced concrete sleepers with epoxy

compound. On the gasket 14, which has two clips 17 through the holes 16, a radio frequency tag 11 (tag) is temporarily installed with information recorded in its memory about the types and volumes of work performed on the site. Radio frequency tags 11 (tags) are placed in the middle of the sleepers. The gasket 14 is mounted on the sleeper 13 once before starting work on the site, and the radio frequency tag 11 (tag) is installed on the gasket 14 in front of each working window.

The operation of the device is as follows.

When the track machine moves along the railway track, the radio frequency identification transceiver 9 (reader) continuously polls the radio frequency tags 11 (tags) and, when passing over the radio frequency tag 11 (tags), gives a signal to the on-board computer 7 about its passage over the radio frequency tags 11 (tags) and all information recorded in the radio frequency tag 11 (tag). The on-board computer 7 can overwrite all the information in the RF tag 11 (tag). Part of the memory of the RF tag 11 (tag) may be with limited access for various users with a password. In the memory of the radio-frequency tag 11 (tag), you can store: the name of the track section, the picket, the characteristics of the track’s upper structure, rail characteristics, and contact network characteristics.

Thus, the proposed utility model by means of simple re-equipment of any track machine makes it possible to make a new generation machine out of it, in which all information about the state of the track is stored directly on the railway track. Information is also transmitted directly through the railway. The machine is multifunctional, high-performance, allows you to rationally operate the equipment with high quality work.
