The invention relates to a device registration status turnouts or crossings with sensors monitoring the end position of astramovich rails, in particular for diagnosing wear and define the intervals at which maintenance inspection.

It is known a device for recording the status of switches and crossings containing installed in all of astramovich rails sensors control their end position, with actuators that interact with the frame rails and connected with the indicator.

A disadvantage of the known device is that it does not provide a diagnosis of deterioration of the wag.

The purpose of the invention is the extension of EC is relochnyi translations and their crosses, containing installed in all of astramovich rails sensors control their end position, with actuators that interact with the frame rails and connected with the indicator, between mathematical center and edge crosses the sensor is installed to register the deviation of the vehicle wheels moving over the switch, in the lateral and vertical directions with Executive management, the building of which, interacting with the wheel of the vehicle, is mounted on the pole can move in a vertical plane and provided with a tapered extension at side sleepers and side edge crossings associated with the housing and indicator elements fixing pressure wheel, moreover, the faces of the housing formed by the same angle as the edge of the crosses.

The objective is also achieved by the fact that the housing Executive level set can be rotated about an axis that is parallel to the bisector of the angle crosses, and made with a cavity in the lower part, with a switch to lock rotation angle, and the fact that the housing is mounted for movement in a vertical plane, and the fixation element pressure vypolnit leaf springs, and fixation of the pressure - in the form of strain gauges, mounted on the inner side, facing each other, the surfaces of the plate springs in the lower part thereof, the free ends of which is mounted on a pole and bent outward, as well as the fact that in the upper part of the body at the junction of the leaf springs between a fixed convex head for engagement with a wheel of the vehicle, and the fact that the cavity formed by the plate springs are filled by weight with long-term elasticity in the form of a synthetic resin or foam, as well as the fact that before the body is equipped with a protective device.

In Fig. 1 shows a diagram of the device of Fig. 2 crossbar switch in an enlarged scale, in the zone of the tip which is the sensor of Fig. 3 - section in the direction of the bisector of the angle crosses through the sensor (the first version of the run) when removing the Executive level; Fig. 4 is a view along the rails on the sensor with the Executive level in the zone of the tip of the spider of Fig. 5 - same embodiment of the sensor of Fig. 6 is a view As in Fig. 5.

In Fig. 1 shows: arrow 1, switch point rails rails 2 which are in position, open the STW alarm, centralization and blocking. In this zone at a distance from the tip end can be provided by the position sensors of wit and minimum passage. Signal the actuator is indicated by the position 4 and is connected to the processing circuit 5. The force transfer arrows and especially the consumption of the actuator arrow energy registered by the processing circuit 5, and the corresponding control lines indicated by the position 6. In addition, schematically illustrates the signal wire 7 which is used for remote control of insulating joint or optionally heating the arrow.

Through the signal line 9 in the area of the spider 8, you can register the minimum distance between the chassis rail and the guide rail, the groove controls or wear in height. On the signal line 10 to the processing circuit 5 receives the data about the bolted connection of the spider. The signals on circuit 5 processing are processed in the processing automatic data processing machine 11, and optionally displayed on the indicator 12.

The location of the sensor in the zone crosses 8 shown in detail in Fig. 2, where the area of the spider shown in an enlarged scale, the zone located outside the running rail with controlsa 13 shows without compliance with the mn receiving gap 14, which narrows to the input size. Gutter width between the edge of the cross lies at a distance from theoretical (mathematical) center-17, which represents a point of intersection of imaginary extensions of the sides of edge crossings. Between the effective edge 16 and mathematical center 17 is a sensor 18, which gives information about sverhdorogimi wear. In close proximity to the sensor 18 in the direction of mathematical (theoretical) center 17 is a protective device 30.

According to the first variant implementation of the sensor 18, he provided Executive level 19, with the possibility of rotation around the axis 20 of rotation (Fig. 3 and 4) that is parallel to the bisector 21 of angle cross members 8 (Fig. 2). Bearing element 22, which can be rotated attached Executive level 19, provided with a hole 23 for the switch, which is actuated by rotation of the actuating element 19. Additionally it may be possible bias element 22 in the vertical direction by the arrow 24, to lock the vertical variation and especially the contact surface of the rolling wheel with the switch. To this end, the element 22 is spring-loaded pruinosa with the upper edge 27 of the Executive management. Excessive wear or exceeding the tolerances decrease the distance 29 between the face of the guiding rail and a lateral side of the chassis rail, which is determined by the gap between contralesa 143 and the cross-piece 7, is indicated in the case, if the crest of the wheel tread will enter into interaction with the side edges 28 Executive level 19, as in this case, the actuating element is rotated about the axis 20, resulting actuates the switch in the hole 23. This option is shown in the drawings without protective devices.

Another embodiment of the sensor 18 (Fig. 5) represents two leaf spring 31 between which enclose an acute angle . On the inner side surfaces of the leaf springs 31 are the strain gages 32. The free ends of leaf springs 31 are bent outward and the strain gages are located in the bends, with the free ends 33 of the plate springs is fixed on the base 34, for example, by means of bolts 35. The acute angle enclosed between the plate springs 31, corresponds to the angle between the faces of edge crossings, while the verge of a cross (Fig. 3) is schematically shown dash-dotted lines 36. Similar Cooma center. In addition, in Fig. 5 at the junction of the leaf springs 31 shows the exhaust cylinder 37.

In Fig. 5 and 6 more shows in detail the mounting of the sensor 18, which is formed from two plate springs placed on them by the strain gages, based on General principles 34. Fastening the free ends of the leaf springs 31 are made through holes in the base 34, while the protective device 30 is welded to the base 34.

To protect the leaf springs 31 and is particularly located inside in the bending area of the strain gages 32, the space between the plate springs 31 are filled by weight with long-term elasticity, such as a synthetic resin or foam.

In addition to this basic information about the state of wear of controlso or guardrail or crosses you can use other sensors (Fig. 1), for example, pressure sensors located between the sealing washers and bolt heads crosses, to ensure comprehensive monitoring of the reliability of the switch and especially due to the continuous control of the drive of the arrow and through the use of actual gaps are also observed and when pushed ostrakova reguliruemoi thus the arrow. Continuous measurement of the distance between the face of the guiding rail and a lateral side of the chassis rail using contact and non-contact measuring means provides additional information which can't be obtained by using only non-contact measurement tools. First of all, it becomes possible to control certain limit and fundamental values during the passage of the arrow and advance fixing unacceptable loads on the edge of the spider. Thanks to continuous monitoring of the tightness of the bolted joints using pressure sensors or strain gauges in a timely manner is detected by the loosening of bolts that exceed a certain limiting value. The usual control fit someone said damage and disconnection of the wag with the magnetic field and the induction field or even with the help of infrared sensors can be under continuous monitoring and recording in advance to detect changes in the characteristics of the fit or wear surface of the rail switch point rails in excess of limits. Continuous monitoring efforts permutations power consumption of a drive motor allows you to determine th environmental pollution, caused by excessive lubricant consumption.
