The invention relates to railway transport and can be used for diagnostic tools rails laid in the way, particularly for funds that use combined ultrasonic and magnetic methods of nondestructive testing with higher resolution.

Known rail inspection car, which houses the control equipment registration system, under the car is a special trolley to place a tracking system and ultrasonic sensors, the cart is attached to the car frame and contains pneumatic and manual system recovery in the transport position (see L. Fendrich Rail. Int. in 1991, No. 6/7, s-32).

The disadvantages of the known devices include using only ultrasonic non-destructive testing method, the lack of dynamic stability of the device when driving on the track, but also a relatively high weight and dimensions.

Closest to the invention is a mobile tool for monitoring of railway track, comprising a carriage, a frame which is fixed defectoscopy cart support device is located on the axis of the rail and pressed thereto by wheel-pneumatic system. During the control of a steering wheel of this system moves along the edge of the rail head, providing tsirovanna the position of the ultrasonic transducers. In the transport position transducers raised, and the idler wheel does not touch the rail (see US 4468966, 73-636, 04.09.84).

The disadvantages of the known means is not sufficiently high resolution diagnostic tools rails, low dynamic resistance of the device when driving on the track, but also high weight and dimensions.

The technical result is to increase the resolution diagnostic tools rails, to increase dynamic stability of the device when moving along the track and to reduce mass and size parameters.

The technical result is achieved by the fact that the mobile device to control the track, including the vehicle on a frame which is fixed defectoscopy trolley with pneumatic and manual system recovery in the transport position, and in the witness of the ski, is attached to the chassis testing truck, mounted block converters ultrasonic inspection device, equipped with pneumatic system forced down defectoscopes truck to the rails, configured to adjust the magnitude of the force of the clamp on the vertical axis, and the cross stabilization, consisting of a roller carriage with elastic damper support, the axes of wheel pairs defectos the Noah carts are placed and interconnected successively magnetizing coil of the magnetic inspection device, the inductive sensor is installed for block converters in the rear part of the witness of the skis relative to the direction of movement defectoscopes truck, the magnetizing coil is mounted on bearings and are located in a protective cover fixed to the frame defectoscopes truck, the housing unit converters, protective cover and frame defectoscopes truck is made of a nonmagnetic material, and the wheels defectoscopes truck installed with the possibility of their independent rotation.

The vehicle may be a machine or a self-propelled truck or vehicle can be made on the basis of the car.

The drawing shows a schematic depiction defectoscopes truck fixed on the frame of the car.

Mobile device for controlling the track consists of a vehicle on a frame 1 which is fixed defectoscopy cart with pneumatic 2 forced down to the rails, configured to adjust the magnitude of the force of the clamp on the vertical axis, manual system 3 and a pneumatic system (not shown) of the boom in the transport position, the device 4 transverse stabilization, consisting of a roller carriage 5 with the elastic damper support, the axes of wheel pairs defectoscopes truck placed and connected to the interconnected successively magnetizing coil of the magnetic inspection device (not shown), inductive sensor 6 magnetic device control installed by block 7 transducers in the rear part of the witness skis 8 relative to the direction of movement defectoscopes truck, the magnetizing coil is mounted on bearings and are located in a protective cover fixed to the frame defectoscopes truck, building block 7 transducers, protective cover and frame 9 defectoscopes truck is made of nonmagnetic material, the wheel 10 defectoscopes truck installed with the possibility of their independent rotation.

Before starting the movement of the mobile device to control the track to the testing area path defectoscopy cart with pneumatic system or manual system 3 is installed in the transport position. Installed in the car diagnostic equipment connected to the unit 7 transformers, the magnetizing coils and inductive sensor 6, and logging off. The controlled part of the way to control defectoscopy cart with pneumatic system (not shown) or manual system 3 is transferred from the transport position into the working position. Included pneumatic system 2 forced clamp for rails. The necessity of using pneumatic force clamp for rails due to the Jena implementation defectoscopes truck with a small structural mass (about 6-7 times less compared to the currently used defektoskopie trucks). The ability to adjust the magnitude of the force of the clamp on the vertical axis allows you to set the desired value of the clamping force with regard to the weight and the operating speed defectoscopes truck, thereby providing the necessary stability when driving defectoscopes truck in the working position. The enforcement of the clamp to the rails on the vertical axis, using the cross-system 4 stabilization, consisting of a roller carriage 5 with the elastic damper support, and installation of wheels 10 truck with the possibility of their independent rotation enabled to provide a desired fixed position transducers of the ultrasonic inspection device placed in block 7 of the converters, and the inductive sensor 6 magnetic device control. When this is achieved the required accuracy of control and high resolution. To reduce the stray fields from the body of the unit converters, protective cover and frame defectoscopes truck is made of nonmagnetic material. The implementation of these design elements of a nonmagnetic material, and installation of the inductive sensor in the rear part of the witness of the skis relative to the direction of movement defectoscopes truck and placing on the axis of wheel pairs defectoscopes truck magnetizing coils with their serial connection allows the t to minimize the impact of these design elements to work converters diagnostics, as well as the interaction between transducers of ultrasonic inspection device and the inductive sensor and the magnetizing coils of the magnetic inspection device. This fact enabled by combining two methods based on different physical principles, to get the effect that exceeds the total efficiency separately used magnetic and ultrasonic methods carriages and flaw detectors. Use combined ultrasonic and magnetic methods of nondestructive testing allows the highest degree to ensure the identification of defective rails at an early stage of their development. Upon completion of the diagnostic instrumentation and logging off, off pneumatic system 2 forced clamp for rails and defectoscopy cart with pneumatic system or manual system 3 is installed in the transport position.

SUBSTANCE: invention relates to methods of continuous recording of spatial position of track gauge. Proposed method includes recording of information from pickups of rail-to-rail space, covered distance, current course angle, longitudinal and cross grades at vehicle running and calculating of current coordinates of track gauge using data of pickups.

Device for determining spatial parameters of rail tracks has running truck including support wheel and first and second measuring wheels and odometer wheel arranged on one axle over one of rail lines. Support wheel is connected with measuring wheels by link installed at angle of 90° relative to direction of running. Track gauge width pickup is installed on said link.
