The invention relates to electric rail transport, intended to control the spatial position of the current-removable part of current collectors.

The purpose of the invention is to improve the accuracy of control.

FIG. 1 shows a device for monitoring the spatial position of the current-collecting part of the current collectors, a general view; in fig. 2 same, top view; on

FIG. The same, side view in the direction of the tram; in fig. 4 - probe; in fig. about the same, side view

The device 1 is fixedly mounted over the tracks at the height of the contact wires 1. The contact wires are fixed to the track bus 3 of the device with the help of end clamps 4.

To compensate for the torque that occurs when forces are applied to the device from the contact wires 2, equilibrated cables 6 are fixed to the frame through insulators 5 using end wedge clamps 7.

The running tire 3 is fastened through insulating gaskets to the lower frame 8, which is rigidly connected to the upper frame 9. to form a spatial frame. The top frame is the base for mounting the insulating bar 10 with probes 11 and two brackets 12 to which the side probes 13 are attached.

In order to increase the reliability of the device and the safety of the staff of Chicago 3, it can be isolated from the contact wires 2 suitable for it using sectional insulators 14, allowing the movement of trams in both the forward and reverse directions ... Then the movement of trams in the control zone should occur by inertia, in case of an unforeseen stop of the car.

The probe consists of a bracket 15, which is mounted on the sensor 16, made with. A non-contact grounding switch, for example, a BVK-231-24 and a swing lever 17 with control plates 18, pivotally mounted on a horizontal base 19, and attached to the insulating bar 10 by means of a threaded pin 20, which allows adjusting the probe installation. in the vertical plane

The device works as follows

P) and the movement of the tractor in the zone of control, its current collection part in series contacts with the code bus 3 of the device in a wide range with the entire surface of the contact insert. The probes 11, which are installed symmetrically to the tire, control the spatial position of the collector part of the current collector followers at points located symmetrically.

relative to the axis of symmetry at an equal distance from the points on the contact insert, which are at the same time in contact with the running tire 3, while the ends of the running tire 3 and their corresponding probes And are located from the axis of the track at a distance of maximum removal of the contact wire .

At any time, each point of the contact insert, which is in contact with the chassis tire 3 of device I, corresponds to a point symmetrically located, lying in the same horizontal plane, on the surface of the contact pin, whose spatial position is monitored by probe 11. deviations in the horizontal plane, the ends of the probes 13 will enter into contact with the current collector only at those points whose locations in space are outside the permissible limits, as indicated by the electrical circuit The device will emit a signal to the corresponding lamps of the mimic circuit, the registration and information blocks, and, if necessary, a sound and light signal.

The number of control points and, accordingly, the number of probes i 1 can be increased by reducing the angles between the planes of placement of the probes 11 and the running tire 8. In this case, the device can be used to control the wear of the contact surface of the current collector part of the current collector. In this way, the accuracy of control and monitoring of spatial deviations of current collectors with an accuracy of 1 mm can be improved.
