Description

The inventive utility model relates to mobile control and measuring devices designed to check the condition of the railway track, and is a tool for diagnosing rail tracks, containing a trolley mounted on rails, equipped with the necessary measuring equipment and devices for determining track parameters and (or) diagnostics of rail defects. The trolley is a removable structure, has a small weight, is moved and removed from the rails by maintenance personnel manually.

Known removable travel trolley containing a frame and traverses resting on the measuring wheels, one of which is rigidly mounted on the frame, and the second is mounted on a rod mounted on the frame with the ability to move along it and the possibility of limited rotation, mounted on the frame level position sensor, a track position sensor along the track gauge, connected to the measuring wheels through a movable traverse, and a recording unit connected to the indicated sensors (see AS SU 1041613, IPC E 01 B 35/00, publication date 09/15/1983 , "Tracking trolley").

A disadvantage of the known design is the narrow focus of the diagnostics of the track measuring equipment, which consists in measuring two parameters of the rail track: the position of the track along the gauge and the position of the track along the level.

However, during the operation of the rail tracks, it is also necessary to check for defects in them, which requires the presence of other special equipment, for example, for ultrasonic or magnetic control, and for this purpose a separate special trolley equipped with flaw detection equipment is currently used.

Also known is the design of a flaw detector mounted on a trolley and designed for continuous ultrasonic testing by echo-pulse and mirror-shadow methods of both strands of a railway track. The flaw detector contains five independent flaw detection channels on each side of the cart, two of which work with inclined transducers (input angles of 55 ° and

70 °) for echo detection of internal defects in the rail head, two with inclined transducers (45 ° input angles) for echo detection of internal defects in the rail neck, and one with separately combined for detecting defects in the rail neck echo - and mirror-shadow methods (Ultrasonic flaw detector UDS2-RDM-2, Republic of Moldova, Chisinau, http://www.rdm.md/rus/rdm2.html).

The known flaw detector is designed to detect and register defects in both rails of a railway track during continuous monitoring for selective manual control of welded joints, individual sections and sections of the rail, determining the coordinates of the detected defects and their conditional length. The flaw detector remembers and registers defectograms of the controlled path with the possibility of viewing on the screen its color matrix indicator or on a computer monitor.

But it is not intended for measuring path parameters. Therefore, in addition to checking the rail track with a flaw detector, it is mandatory to carry out track-measuring measurements, which are carried out using special track-measuring removable trolleys.

The inability to carry out rail track diagnostics, consisting of track measuring with the simultaneous detection of rail defects, requires the creation of separate specialized track measuring carts and flaw detection carts with the corresponding equipment, which entails significant material costs for their creation and maintenance, additional time costs for maintenance personnel for separate execution measuring and flaw detection diagnostics, as well as additional congestion of glands th road.

The objective of the proposed technical solution is to increase the efficiency of diagnostics of the railway track by expanding the range of simultaneously diagnosed parameters, in reducing material, time and labor costs.

The problem is solved thanks to the creation of a mobile flaw detector - track gauge, characterized in that it is made in the form of a removable trolley mounted on rails, on which an automated

a diagnostic complex equipped with a positioning system, track measuring equipment, flaw detection equipment and a microprocessor system unit.

The implementation of a mobile flaw detector-tracker in the form of a removable trolley mounted on rails equipped with an automated diagnostic complex allows a comprehensive approach to assessing the operability of a railway track by expanding the range of simultaneously diagnosed track parameters.

The presence in the automated diagnostic complex of a system of track measuring and flaw detection equipment ensures its versatility, allowing simultaneously, in one pass of the trolley, to measure the state of the rail track and flaw diagnostics of rails.

The combination of flaw detection and travel measuring equipment in a single complex with a common system microprocessor unit and a positioning system improves the efficiency of diagnostics of the condition of the rail track by providing comprehensive verification and analysis of complex parameters. At the same time, the use of an automated diagnostic complex improves the quality of diagnostics, increases the speed and accuracy of measurement analysis.

In addition, the placement of a universal diagnostic complex on one trolley, instead of two separately existing specialized trolleys, allows you to save significant material resources spent on their separate manufacture and maintenance, as well as reduce overall labor costs for the diagnosis of rail tracks.

At the same time, railroad congestion is reduced by reducing the time it takes to carry out the necessary diagnostic work. The overall weight characteristics of the mobile complex remain within the limits characteristic of a single flaw detector trolley.

The presence of distinctive features in the claimed technical solution allows us to conclude that it meets the condition of patentability “novelty”.

The patentability condition "industrial applicability" is confirmed by the example of a specific implementation.

figure 4 is a structural diagram of an automated diagnostic complex.

Mobile flaw detector-tracker is made in the form of a removable trolley, consisting of a frame 1, on which on one side there are two attachment points 2, rigidly fixed to the frame. The axles of these units are equipped with running wheels 3 for moving the trolley along the rails 4, and locking wheels 5 for fixing and holding the trolley from rolling off the rails 4. Two rotary frames 6 are mounted on the trolley, on which spring-loaded units with axles for the running 3 are mounted and locking 5 wheels. To transfer the trolley in an inoperative position to the place of work, the locking lever 7 is used to compress and fix the spring of the swinging frame 6. To remove the trolley from the track and transfer it outside the railway track, pull-out handles 8 are installed on the frame 1.

The trolley positioning system contains a satellite transceiver mounted on the trolley for determining the location of the trolley on the ground and an angular displacement sensor, which is installed in one of the attachment points 2 and serves to measure the distance traveled, and also synchronizes the operation of the microprocessor unit, which controls the work of the measuring and flaw detector equipment.

Tracking equipment contains electronic units 9 for receiving signals from sensors for measuring gauges of the gauge (width) of the rail gauge and for receiving signals from sensors for measuring the level of rail threads. The measuring mechanism of the rail gauge template is connected by a spring-loaded lever 10 with a pivoting frame 6 of the trolley. The tensile springs 11 provide a constant lateral pressing of all the locking wheels 5 of the trolley to the inner side surfaces of the rail gauge heads, thereby providing control of the rail gauge width.

Flaw detection equipment contains: receiving-generating unit 12; search ski 13, centering system 14 search ski 13; equipment for storing and supplying contacting fluid.

The receiving-generating unit 12 is used for receiving, amplifying and selecting echo signals and for exciting ultrasonic waves in ultrasonic resonators. On the ski ski 13, ultrasonic resonators are installed, which are connected to the inputs of the receiving-generating unit 12. The centering system 14 of the ski search

13 is used to center the search ski 13 relative to the center of the rail head 4. Equipment for storing and supplying contacting fluid under the search ski 13 includes: a container for storing contact fluid 15 (see Fig. 1), supply hoses (not shown in Fig.), through which the contacting liquid from the storage tank 15 enters under the ski ID 13; controls for the quantitative supply of contacting fluid.

The system microprocessor unit 16 (Fig. 4) of an automated diagnostic complex comprises: an interface device 17 for receiving a clock signal from a positioning system; an interface device for communication with a measuring equipment 18 and an interface device for communication with a flaw detector electronic equipment 19; a device for visual display of information 20; storage device 21 received control data; control device 22 software complex; an interface device 23 for receiving and transmitting data to external computers.

After the system microprocessor unit is turned on, the microprocessor is loaded with 16 initial installation programs to initialize internal and external interface devices, preparing the automated diagnostic complex for work. From the control device 22, the initial settings of the flaw detector and travel measuring equipment are entered.

Using the positioning system, we bind the cart to the terrain. All these configuration and binding operations are controlled on the screen of the display device 20. After entering the initial parameters of the monitored area, its diagnostics are started.

At the beginning of the movement of the trolley, the signals from the angular displacement sensor are sent to the system microprocessor unit 16. These signals coming through the same distance traveled by the path of the monitored section synchronize the operation of all communication interfaces 17, 18, 19, 23 of the system microprocessor unit 16. Through communication interfaces 17, 18, 19, 23, data is exchanged between the system microprocessor unit 16 and the positioning system, track measuring equipment, and flaw detection equipment.

The obtained measurement data is supplied to the data storage device 21 for storage. Read by the microprocessor 16, data from the data storage device 21 is supplied to the display device 20 (screen).

Management of the selection of information from the data storage device 21 and its output to the screen of the display device 20, as well as the selection of the operating modes of the measuring and flaw detection equipment or items in the software menu of the automated diagnostic complex, is carried out by the control device 22.

The obtained control data can be transferred to an external computer for further processing.

Thus, the inventive mobile flaw detector-tracker, equipped with a new automated diagnostic complex, consisting of a positioning system, track measuring equipment, flaw detection equipment and a system microprocessor unit, provides an integrated approach to diagnosing the condition of the railway track, allows you to expand the range of simultaneously diagnosed track parameters, improve quality and reliability of measurement results, as well as their processing and analysis.

The claimed technical solution increases economic efficiency both in the manufacture of a mobile flaw detector-tracker, and during its operation due to a single pass while simultaneously conducting line-measuring measurements and defectoscopy diagnostics.

These technical advantages provide, on the whole, an increase in the efficiency of diagnostics of railway tracks, increasing the safety of their operation.
