The excavation proceeds while water is supplied to the cutter head 11. Excavation proceeds while the excavated soil is discharged to an excretion pipe together with water. The position and the propulsion direction of the excavator 10 are continuously measured, .

Here, the conventional directional control device for a tilting machine includes a target having a surface light source for measuring a position and a propulsion direction of the cutter head 11 of a tilter 10 for excavating underground, And a jack for controlling the propelling direction of the cutter head 11 in accordance with the measurement result is connected to the cutter head 11.

2 to 6, the directional control device for a tiltable excavator according to a preferred embodiment of the present invention includes an excavation start position from a pipe inlet 1 to an expected arrival position A trough 100 for excavating the gravel to an outlet 2 of the pipe and forming a channel through the buried buried pipes 20 connected to the rear by performing a plowing operation, A transmitting means 200 comprising a transmitter 220 for supplying an electric current to the transmitting coil 210 and transmitting electromagnetic waves for forming a magnetic field having a predetermined phase from the transmitting coil 210 toward the duct outlet 2, The electromagnetic waves w1 transmitted from the transmission coil 210 and the electromagnetic waves w1 transmitted through the plurality of reception coils 310 arranged in the 'L' or '+' The phase induced by the peripheral induced current having a different magnetic field And a receiver 320 for receiving an electromagnetic wave w corresponding to a composite magnetic field with the JAW wave w2, a receiving unit 300 configured to perform Fourier transform on the received electromagnetic wave w, (400) for separating and detecting an electromagnetic wave (w1) having a magnetic field of a phase and a component of an electromagnetic wave (w2) having a magnetic field having a phase different from that of the electromagnetic wave (500) for calculating an output magnitude, and a calculation unit (500) for calculating an output magnitude of the electromagnetic wave And a direction control means 600 for controlling the advancing direction of the tilting machine 100 to be smaller than the magnetic field of the tilting machine 100 so that the tilting machine 100 is aligned with the propelling schedule line.

The excavator 100 excavates the excavated soil from the excavation starting position (1) to the pipeline exit (2), which is a position to be reached, for the burial of the buried pipe (20) The cutter head 110 has a generally cylindrical shape and corresponds to a front portion of the pushing direction and has a half-round shape. The cutter head 110 has a cylindrical shape, A jack 120 for controlling the driving direction of the cutter head 110 and a discharging means for discharging the excavated soil from the cutter head 110 to the rear, (130), and the like.

Here, the tilting machine 100 may have a known structure as disclosed in, for example, Japanese Patent Laid-Open No. 10-2015-0099533, and thus a detailed description thereof will be omitted.

The transmitting means 200 includes transmitting coil 210 wound around the front component of the tester 100 and means for transmitting electromagnetic waves having a predetermined phase to the receiving means 300, And a transmitter 220 which is located on the ground and supplies a current to the transmission coil 210 so that an electromagnetic wave that forms a magnetic field having a predetermined phase from the transmission coil 210 is transmitted toward the channel outlet 2 .

The transmitting coil 210 is wound around the cutter head 110 of the tilting machine 100. More preferably, the outer circumferential surface of the cutter head 110 is formed with a groove having an L- The opening portion 111a of the winding groove 111 is formed by winding an O-ring (O) having a synthetic resin material, Sealed manner.

Here, the winding groove 111 in which the transmission coil 210 is wound has a concave structure of a wired "L" shape when viewed from the end face on the outer peripheral surface of the cutter head 110, As the diameter is about several meters, it takes a long time to wind up the coil. If it has a concave shape, the surface of the continuous enameled wire becomes uneven. In the case of the partially wound enameled wire, The surface of the wind-up portion, which is pushed to the edge, is exposed to the outside and does not have an even distribution, thereby failing to perform its function by being easily broken when rubbing against the stone or the like in the soil.

Thus, when the winding groove 111 has the "L" shape of the wire, the enameled wire wound around the opening 111a is pushed to the inside of the receiving portion 111b by the continuous enameled wire So that the wind-up work can be carried out easily and quickly, and the wind-up part of the anamelous wire is mostly located inside the accommodating part 111b, and there is no fear that it is directly rubbed against the stone or the like in the soil, Even if the coil is broken due to the stone in the soil, the maintenance can be performed quickly and the working efficiency is improved.

In addition, since the O-ring O having a diameter corresponding to the diameter of the opening 111a is sealed in an interference fit manner, the opening 111a is filled and cured with an epoxy resin or the like, Maintenance costs can be reduced.

The receiving means 300 is a means for receiving electromagnetic waves transmitted from the transmitting coil 210 of the tilting machine 100 and includes a plurality of And a magnetic field having a different phase from the electromagnetic wave w1 transmitted from the transmitting coil 210 through the receiving coil 310 and a peripheral induced current caused by the magnetic field of the electromagnetic wave w1 And a receiver 320 for receiving an electromagnetic wave w corresponding to a composite magnetic field with the electromagnetic wave w2.

The reception coil 310 provides a function of receiving the magnetic field of the electromagnetic wave transmitted from the transmission coil 210. The reception coil 310 is provided with a plurality of 'L' or '+' And has a directionality corresponding to the placement position.

Here, an AC magnetic field is used in the receiving coil 310 to distinguish the electromagnetic wave w1 from the magnetic field (DC magnetic field) when the electromagnetic wave w1 according to the magnetic field having a predetermined phase is transmitted from the transmitting coil 210 An electromagnetic wave w2 generated by a magnetic field having a phase different from that of the electromagnetic wave w1 is generated due to an induced current of a metal or the like in the ground. At this time, the electromagnetic wave w2 has a cosine wave And the electromagnetic wave w corresponding to the composite magnetic field in which the sine wave and the cosine wave are synthesized is received.

The receiver 320 has a plurality of reception coils 310 arranged in an 'L' shape or a '+' shape so as to have a directivity with respect to the propelling planes, And separates the sine wave and the cosine wave to detect an electromagnetic wave w1 corresponding to a magnetic field having a predetermined phase transmitted from the transmission coil 210. [

Here, the receiver 320 includes a band-pass filter for receiving electromagnetic waves (w) according to a plurality of synthesized magnetic fields from the reception coil 310 and extracting the same waveform, an amplifier for amplifying the signal strength of the extracted waveform And an A / D converter for converting the amplified signal from analog to digital.

At this time, it is preferable that the receiver 320 and the transmitter 220 synchronize the electromagnetic wave w1 and the received electromagnetic wave w which are transmitted in synchronization with each other by GPS or the like.

The detecting means 400 and the calculating means 500 perform a Fourier transform on the received electromagnetic wave w to generate an electromagnetic wave w1 having a magnetic field of a predetermined phase transmitted from the transmitting coil 210, The components of the electromagnetic wave w2 are separated and detected and computed. The digital-converted signal is Fourier-transformed to separate and detect a sinusoidal wave having the same phase as the predetermined phase transmitted from the transmission coil 210 and a cosine wave having a different phase And calculates the output magnitudes of the plurality of electromagnetic waves (w1) having the magnetic field of the predetermined phase detected separately.

The direction control means 600 controls the tilting direction of the tilting machine 100 so that the tilting machine 100 is aligned with the propelling plan line so that the receiving coil 310 is in the 'L' The plurality of electromagnetic waves w1 have respective directivities because the plurality of electromagnetic waves w1 have the same directionality with respect to the propulsive planar line, and when the electromagnetic waves have the same size, It is determined that the direction of advance of the tilting machine 100 is in the direction of a large electromagnetic wave when the electromagnetic wave has a different magnitude and it is determined that the direction does not coincide with the propelling plan line.

If the calculated output power of the plurality of electromagnetic waves (w1) is different from each other, it is determined that the electromagnetic wave (w1) has deviated from the propelling plan line and a small output The pushing amount of the jack 120 of the tilting machine 100 is adjusted so that the direction of the tilting of the tilting machine 100 is controlled to correspond to the propelling plan line.

 Therefore, when the buried pipe 20 is buried in the ground by using the excavator 100, the receiving means 300 installed on the pipe exit 2 side is transmitted from the transmitting means 200 of the excavator 100, It is possible to accurately measure the tilting direction and to control the tilting direction so that the tilting machine 100 can be precisely guided to the expected arrival position.

In addition, a transmitting means (not shown) formed of anamelic wire is attached to the outer circumferential surface of the cutter head 110 of the tilting machine 100 in a winding groove 111 having a concave structure of a streamlined 'L' The opening portion 111a of the winding groove 111 is sealed by the O-ring O having a synthetic resin material in a forced fit manner, Thereby simplifying the coil installation work and reducing manufacturing and maintenance costs.

Although the present invention has been described with reference to the specific embodiments, various modifications may be made without departing from the scope of the present invention. Accordingly, the scope of the invention is not to be determined by the embodiments described, but should be determined by equivalents of the claims and the claims.
