Abstract

This invention relates to a device for monitoring rail track gauge. The purpose of the invention is a new operational reliability. The track-measuring trolley contains body 1, a line of 2 reed switches is mounted on the koTopoM, and a movable rod 3. The switches of the | -ercons are interconnected and connected to the plus of the power source. The reed switch outputs are connected to the power amplifier 8 and the circuit OR 7. Under the reed switch line, an electromagnet 4 is installed on the rod. It is connected to the output of the sawtooth generator 5, which is started by timer 6. The result of the measurement is displayed on the board 9 connected to decoder outputs 8. 1 pl. sl co oi oo

Description

This invention relates to a device for measuring the ring elimination of rings of an elz transport.

The purpose of the invention is to increase operational reliability.

The drawing shows a functional circuit diagram of the measuring trolley.

The track-measuring trolley contains a corn 1, on which a line of 2 reed switches is fixed. A control electromagnet 4 is mounted on rod 3. The register unit includes a sawtooth generator (GNN) 5, timer 6, circuit OR 7, decoder 8, and digital display 9 (power supply is not shown on the diagram).

The recording unit may be located directly on the device case or may be placed on HJ. iaiire and zakrenlei, for example, on the operator's chest.

Track measurement te.chzhka works in harmony, they form.

When installing And ablo11 pa rails, the uniValuy electromagnet 4 is set depending on the 1-rip gauge against one of the reed switches.

In the initial state of the circuit, the control unit of the electromagnet 4 is de-energized, all the screws of the ruler 2 are disconnected, and on the digital display 9 the result of the airless measurement is displayed. When the current from timer 6 is started, the FPG 5 is started and dropped to the display of display 9. With the increase in voltage supplied from the FPG 5 to the winding of the electromagnet 4, the magnetic flux of the nose, 1 moment also returns and the moment comes.

4 g srcon closest to the electromagnet is included. The positive notional from the closed reed switch nostunat to one of the inputs of the circuit OR 7 and turns off the FPG 5. The current in the winding of the electromagnet 4 stops and the gyro switch turns off. However, the signal from the included reed switch will also be sent to the corresponding input 1. of the decoder 8. Depending on the number of the reed switch turned on, the value of the measured gauge is displayed on the display 9. After turning off the handgrip, the information on the display 9 is saved - until the next pulse of timer 6 is opened.
