(57) Abstract:The invention is intended for use on railway vehicles for measuring podoloski rails of the railway track. The device comprises a bar mounted on the head rail. At one end there is a plate with a measuring scale, the arrow and the stop for engagement with the side face of the rail head. Arrow is set on the axis and pressed against the sole. The technical result is to increase the measurement accuracy while simplifying the structure. 1 Il. The proposed device is intended for use on railway transport for measuring podoloski rails.A device for measuring podoloski rails of the railway track, p/N 55690 the USSR, CL E 01 35/02, 1939, containing bar, mounted on the rails in a controlled path section and carrying at one of its ends the plate with a measuring scale, the affinity, the deviation of which relative to the scales measure pagoclone and the emphasis in the bottom rail, the locking position of the device relative to the measured rail.The main disadvantage of this device is extremely low accuracy is otnositelno fixed focus translational and on the measuring scale is transmitted readings without zoom, that limits the measurement accuracy especially at small deviations of the measuring means. In addition, the emphasis, the locking position of the device, is located here by rail, facing the inside of the track that does not allow the measurement of podoloski rails if contrails.A device for measuring podoloski rails of the railway track (see Henrich Baluch. Diagnosis superstructure. M. Transport. 1981, page 146, Fig. 3.85), containing bar, mounted on the rail head and carrying at one of its ends the plate with a measuring scale, the vehicle, the deviation of which relative to the scales measure pagoclone, and a stop for engagement with the side face of the rail head, mounted on the plate.The advantage of this device in comparison with analog is that the entire plate with a measuring scale and a means of measuring the outside of the track and controls does not interfere with the measurement of podoloski the main rail. The tool dimensions are presented in the form of a system of levers, allowing for differences between the shoulders to increase the accuracy of the measurements. However, the increase in accuracy is achieved here by uvelicheniya size and weight of the entire device as a whole. As for portable handheld devices increase the weight and size is highly undesirable, in this construction it is impossible to achieve a significant increase in scale of measurement, and hence the accuracy of the instrument.Thus the disadvantages of the device are:
- limited measurement precision;
- the complexity of the design lies in its mnogodelnosti;
and, as a consequence, the size and weight of the device.However, this device is the closest in design to the declared object.The task of the invention is to improve the measurement accuracy, eliminating the complexity and mnogodelnosti design and to minimize its size and weight.The solution provided by the fact that in the proposed device the vehicle, the deviation of which relative to the scales measure pagoclone is a (single) arrow mounted on the axis for rotation and presses the spring to the bottom rail.The essence of the proposed technical solution is illustrated by a drawing, which shows a device for measuring podoloski rails in working on the us support surface 2 is the first protruding element 3, attached to the strip 1, for example, by welding and perpendicular to this plate 1. At the same end of the strap 1 is placed measuring scale 4. On the first protruding element 3 adopted arrow 5, the vehicle, the deviation of which measure pagoclone, with the possibility of rotation around the axis 6 perpendicular to the element 3. The spring 7 is trying to turn the arrow 5 in a clockwise direction (in the plane of the drawing). One end 8 of the arrow 5 extends over the edge of the end of the element 3. The second end 9 of the arrow 5 is moved in the field of measurement scales 4.The device also includes a second protruding element 10 located at the side of the supporting surface 2 of the strap 1 and perpendicular to the surface 2. The protruding element 10 is displaced relative to the speaker element 3 toward the second end of the strap 1 at a slight distance so that the end 11 served as the focus in the side of the head rail 12. Items 3, 10 and a scale of 4 made in the form of a single plate on which are mounted the axle 6 of the arrow 5 and the spring 7.The device operates as follows. Before proceeding it is installed on the rail head 12 and 13 of one of the rail track. The upper limit of 1 is based surface 2 at Glisy rail 12, Padukone surface which is to be measured. In this case, the end 8 of the rod 5 is located slightly below the soles of the rail 12.To measure podoloski the bar 1 is moved across the rail track in the direction of the rail 13 as long as the protrusion 11 is not pressed against the outer side surface of the rail 12. At the same time the arrow 5, clinging to the rail by means of the spring 7 end 8 remains in contact with the sole of the rail 12; the specified movement causes rotation of the arrow 5 about the axis 6 and the displacement of its end 9 along the scale 4. The angle of rotation 5 is proportional to the angle of deviation from vertical X-axis rail 12 and, hence, allows to quantify the magnitude of podoloski rail.Since the length of the part of the arrow 5 from the axis 6 to the end 9 may be substantially (several times) greater than the distance from the axis 6 to the contact point 14 of the arrow 5 with bottom rail 12, even a slight displacement of the point 14 will cause several times greater deviation of the end 9 of the arrow 5 on a scale of 4. This achieves high accuracy while reducing the number of parts, dimensions and weight design.We are not aware of technical solutions, in which Sov railway track, containing the bar mounted on the head rail and bearing at one of its ends the plate with a measuring scale, the vehicle, the deviation of which relative to the scales measure pagoclone, and a stop for engagement with the side face of the rail head, mounted on the plate, characterized in that the specified tool is an arrow mounted on the axis for rotation and presses the spring to the bottom rail.

SUBSTANCE: method of pulling contact system cable comes to the following: each rail 6 is read off by means of distance pickup 16 placed over rail and moved continuously in longitudinal direction of track and scanning in plane 20 passing square to longitudinal direction of track. Problem points of measurement 25 on rail defining geometry of switch are recorded as measurement values in polar system of coordinates. Polar coordinates for measurement values are converted into Cartesian coordinates and information is recorded in memory at continuous measurements of distance by means of measuring wheel after which lateral section for switch 1 is calculated basing on recorded measurement values. Actual measurement values are compared in definite points of measurement 25 with preset values of at least two of enumerated parameters kept in memory, namely, width of clearance between counter-rail and running rail, through clearance or state of tongue as to its wear, minimum width between edge of guide rail and side edge of running rail in curve, width of gauge and/or distance between counter-rails or guide surfaces and deviation of obtained values from preset values.
