The invention relates to the study of the rail track for the movement of vehicles, to the mobile measuring apparatus for measuring the position of the path.

A device for measuring the position of the track containing supported on the wheel frame, a bearing unit for measuring the position of the path, swei transverse axis (AV. USSR N 1 276715, CL E 01 B 35/04, 1986).

The disadvantages of the known devices include the fact that it is not adjust to any misalignment of the wheels of the trolley relative to the rails of a track and do not provide simultaneous removal of all information necessary to determine the spatial characteristics of the track.

The technical result for which the invention is directed is to improve measurement accuracy by providing a tracking wheel contact points of rails of a track, as well as implementation of a frame of articulated sections, with the possibility of relative rotation in a vertical transverse plane. This excludes the possibility of disengagement of the at least one wheel to the contact surface of the rail, which distorts the results obtained, and the skew measuring unit relative to the actual position of the rails of a track. The installation of each wheel with the possibility of elastic axial movement along the axis provides a permanent connection of each wheel to the appropriate rail. With the introduction of the uprights connecting the axles to the frame, formed podrobnee space for placement of various types of traction organicheskoi of the device for measuring the position of the track, containing supported on the wheel frame, a bearing unit for measuring the position of the path associated with recording equipment, while each wheel is mounted rotatably on a standalone transverse axis, each axis is connected with the frame with the rack installed in the past with the possibility of axial movement and the lock turn, and each wheel is mounted on the external area of the corresponding axis can be rotated in a horizontal plane and is spring-loaded relative to the rack and the frame consists of two articulated sections, with the possibility of relative rotation in the transverse vertical plane, and one of them has specified block.

In addition, the axis in the zone of interaction with a rack in the transverse cross-sectional shape polygonal, and rack the corresponding shaft hole on the inner end of each axle is fixed perpendicular to her plate to limit the movement axis relative to the rack carrying the actuator motion sensor for measuring gauge mounted on the rack, and at least one of the wheels includes a probe traversed path.

In Fig. 1 image is, 3 node 1 Fig. 1; Fig.4 section l-l of Fig.1.

Device for measuring the position of the path contains based on wheel 1 for movement along the rails way the frame 2, the bearing unit 3 for measuring the position of the path associated with the recording equipment (not shown). Unit 3 to change the position of the path is airtight. Posted by equipment (not shown) for measuring the position of the track, for example, girovertikal and azimuth gyro rigidly mounted inside the unit 3 on its body, while unit 3 is rigidly fixed on the frame 2. Recording equipment may be stationary, and devices for measuring the position of the path associated with the communication line (not shown). Each wheel 1 is mounted on the axis 4, is associated with the frame 2 counter 5, and the last with the possibility of axial displacement of the lock turn and come pre-loaded outwardly by a compression spring 7. Section 6 axis 4 in the zone of interaction with the stand 5 in a transverse cross-sectional shape polygonal, and the rack is made corresponding to the shaft hole. Section 6-axis form with covering part of it stands virtually precision couple of slides, which eliminated the distortions axis, and hence associated with h is the head rail (not shown). The wheel 1 is mounted on the outer section of the axis 4 by means of a hinge 8 with the possibility of bending the track in the horizontal plane. The frame 2 is formed of two articulated hinge 9 sections. The hinge 9 provides relative rotation of the sections in the transverse vertical plane. This block 3 is mounted on one of the sections, thus tracking the spatial position of the investigated rails. On the inner end of each axle 4 is fixed perpendicular to her plate 10 to limit the movement of the axis 4 relative to the rack 5. The plate 10 is rigidly attached to the actuator 11 of the sensor 12 is moved to the measurement gauge that is installed on the rack 5. The sensor 12 is moved to the measuring gauge can be made in the form of a circular linear potentiometer, rotary transformer selsyn transmitter, or similar element, converts linear displacement into an electrical signal proportional to this displacement. At least one of the wheels 1 is the sensor 13 of the traversed path, locking wheel revolution.

The device operates as follows.

At the beginning of the operation of the device for measuring the position of the path setting is on the action on the wheels of the compression spring 7 and the total mass of the device. Next, the process of measuring the required parameters of rail track in compliance with the technical conditions and requirements for all components during operation. Due to the fact that each Autonomous axle 4 is connected with the frame 2 counter 5 is set in the past with the possibility of axial displacement and blocked from turning, and the wheel 1 are drawn outward by a compression spring 7, and the fact that the wheels 1 are mounted using a hinge 8 on the external plot axis 4 can be rotated from a horizontal plane, and the execution of frame 2 of two sections, with the possibility of rotation relative to each other in a vertical transverse plane, is adjust to any misalignment of the wheel 1 relative to the axis of the rail track when you move the device and the tracking unit 3 position in contact with the wheels of the points of the rails of a track. This eliminates the possibility of separation of at least one wheel from the contact surface of the rail and the skew measuring unit 3 relative to the actual position of the rails of a track. All this leads to improved accuracy of the measurements. Due to the presence of the uprights 5, connecting the axis 4 of the wheel 1 with a frame 2 formed podrobnee space, providing accommodation razlichnog the truck, designed for lifting the vessel out of the water. Due to the constructive embodiment of the device and the sensors 12 and 13, respectively displacements for measuring the width of the track and trail is kinematically connected with the axes 4 and at least one wheel 1, is provided for the simultaneous removal of all the information about the characteristics of the track.
