Description

one

The device to be polished is designed to lay cable and cable into the ground while controlling the depth of the strip.

The known device containing the cable layer, alternator of alternating current and depth gauge with series-connected inductors does not allow controlling the depth of the cable with the required accuracy directly during the construction of the cable line due to the fact that the depth sensor does not keep constant position relative to the route of the cable being laid and the surface of the earth, from which the depth of the cable is measured in the soil.

In the described device, the noted defect is eliminated.

A distinctive feature of the proposed device is that in order to increase the objectivity of the control, it is equipped with a trolley connected to the cable layer, and the coils are mounted on the axis of the trolley support wheels at a distance from each other, greater than the possible amount of derailing of the trolley from the track when cornering.

FIG. 1 shows the proposed device in operation; in fig. 2 - device, rear view; in fig. 3 is a structural diagram of the hardware part of the device.

The cable layer 1, laying the cable 2 into the ground, is connected to the carriage 3 having two support wheels 4 fixed on the axis 5. The hardware part of the device has a power supply unit 6, an alternator 7, a receiver and a recorder 8. The generator is connected through contact device 9 cable unwound from the drum 10. The receiver consists of an antenna sensor of depth 11, having two inductors in series, an antenna sensor of the voltage reference 12 and an amplifier-transformer unit 13 with a recorder and an indicator 14. atuschki depth sensor are mounted on the supporting axle bogie wheels. The magnetic axis of the coils is located in the –plane, perpendicular to the path of the laid cable. The coils are separated from each other by a distance greater than that of the trolley.

from the track at its corners.

The registrar is designed as a recorder. Its tape drive mechanism 15 is driven from the support wheel using a flexible shaft 16 (or electromechanical

transfer). The pen 17 of the recorder is connected to its executive electric motor 18 by a flexible coupling 19.

During operation, generator 7 feeds the conductive element of the laid cable

alternating current, the circuit of which closes through the ground and the cable of the cable (ladder. electric field current, flow; 1 through the cable, induces in sensors 11 and 12 the voltage applied to the input of the amplifier-converting unit. The output signal of the latter controls the electric motor 18 , moving the pen of the recorder. The depth sensor maintains a constant distance from the ground when the frame of the tel is rotated in a longitudinal band while it is moving along the track.

By knowing the gear ratio of the rail mechanism, along the length of a diagram tape with recording the depth of the cable, one can determine the locations of the sections of the route with acceptable reductions in the depth of the strip. A diagram of the depth can be used as a coitrol: a document for laying a line.

Subject invention

A device for laying the cable into the ground with simultaneous control of the depth of the gasket, containing the cable layer, the alternating current generator and the depth sensor with inductance coils connected in series, is so that, in order to increase the objectivity of the control, it is equipped a trolley connected to the cable layer, and the coils are mounted on the axles of the support wheels of the trolley at a distance from each other that is larger than the possible amount of derailment of the trolley from the road when cornering.
