[0041] Specifically, a device and method for quick electrode placement for TBM geological exploration includes a support stepping module, a signal control module, an electrode push-up module and other devices mounted on the TBM body. Automatic electrode placement is achieved through the support stepping module and the multi-electrode push-up module, and electrode power supply / measurement function control is achieved through the signal control module, thus realizing the integration of geological exploration instruments and TBM tunneling machines;

[0042] The support stepping module comprises a host computer control module (1), a transmission cable (2), a stepping motor controller (5), a stepping motor driving end (8), a transmission gear set (9), a telescopic support rod (12), an anchor device (10), a TBM body trolley (11), an image module (16) and other parts. The support stepping module is mainly used to control the spatial position of the electrode module. The specific working method is as follows: the host computer control module (1) issues a support stepping module telescopic instruction to the stepping motor controller (5), and the stepping motor controller (5) controls the forward and reverse rotation of the stepping motor driving end (8) according to the telescopic instruction. The stepping motor driving end (8) acts on the telescopic support rod (12) through the transmission gear set (9) to control the telescopic support rod (12). The forward rotation of the motor causes the support module to extend outward, and the reverse rotation of the motor causes the support module to retract inward. The whole set of support stepping modules is fixed to the TBM body trolley (11) through the anchor device (10), and the specific position of the support stepping module is controlled in real time through the image module (16). The entire module moves forward synchronously with the TBM body.

[0043] The signal control module comprises a host computer control module (1), a transmission cable (3), a signal conversion module (6), a transmission cable (14), a multi-electrode module (15) and other components. The signal control module is mainly used to control the specific functions of the electrode module, which is divided into two categories: power supply electrode and measurement electrode. The specific working method is as follows: the host computer control module (1) issues functional instructions to the signal conversion module (6), which are divided into two categories of instructions: power supply and measurement. The input and output functions of the two categories of instructions are realized through the signal conversion module (6), and the final functional instructions are applied to the multi-electrode module (15) through the transmission cable (14) to realize the functional control of the module.

The specific working method is as follows: the upper computer control module (1) issues an extension and retraction command to the hydraulic control module (7), and the hydraulic control module (7) is connected to the hydraulic control device (17) through the oil pipeline (13) and performs functional control; the hydraulic control device (17) is externally connected to a hydraulic extension module: it is composed of a hydraulic push-up module (18), a cable sub-line (19), a hydraulic casing (20), a hydraulic push rod (21) and other components. When the upper computer control module (1) issues an extension command, the hydraulic control device (17) extends the hydraulic push rod (21) inside the hydraulic casing (20) through the hydraulic push-up module (18); when the upper computer control module (1) issues a retraction command, the hydraulic control device (17) retracts the hydraulic push rod (21) inside the hydraulic casing (20) through the hydraulic push-up module (18). At the same time, the hydraulic push rod (21) is externally connected to the copper electrode (22), and the extension and contraction of the copper electrode (22) is controlled by the hydraulic module. A coupling head (23) is installed at the tail end of the copper electrode (22) to ensure the coupling density between the electrode and the surrounding rock wall (24). The electrode push-up module realizes the coupling between the multi-electrode module and the surrounding rock by means of the extension and contraction of the hydraulic rod, while increasing the electrode contact area and reducing the grounding resistance, ensuring that the electrode module can effectively supply power to the surrounding rock / receive current signals.

[0045] like Figure 2As shown, the specific components of the signal conversion module (6) are: a signal controller (27), a signal excitation module (28), a constant current source excitation module (29), a signal receiving module (30), an A / D conversion module (31), and a multiplexer (32). The signal conversion module (6) receives two types of instructions, namely, power supply and measurement, and performs function control in the signal controller (27) according to the instructions. When the module instruction is power supply, the instruction is transmitted to the signal excitation module (28), and power supply information control is performed, including information such as power supply current size, duration, polarity, etc. The power supply information is finally supplied through the constant current source excitation module (29), and the current signal is output to the transmission cable (14) through the multiplexer (32); when the module instruction is measurement, the instruction is transmitted to the signal receiving module (30), and data acquisition signal control is performed. The current signal in the surrounding rock is transmitted to the multiplexer (32) through the transmission cable (14), and the continuous time signal of the multiplexer is converted into a digital signal through the A / D conversion module (31), and is recorded by the signal receiving module (30), and finally transmitted back to the upper computer control software.

[0046] like Figure 3 As shown, the core structure of the multi-electrode module (15) is composed of a hydraulic module body (25) and 25 electrode telescopic modules (26), and the 25 electrodes are evenly distributed on the circular surface of the body, ensuring that the multi-electrode module (15) can be coupled with the surrounding rock wall at any rotation angle.

[0047] like Figure 4 As shown, the specific steps of coupling the multi-electrode module (15) with the surrounding rock wall (24) are:

[0048] (1) The host computer control module issues a test command to support the stepper module to rotate forward and control the multi-electrode module to extend outward. The multi-electrode module stops extending outward when it is 10 cm away from the surrounding rock wall.

[0049] (2) The hydraulic control module issues an extension command, and each hydraulic rod in the multi-electrode module extends outward, pushing the copper electrode on the push rod outward until each electrode is well coupled with the surrounding rock and stops. Since the surface of the surrounding rock wall is uneven, the extension length of each electrode is also inconsistent. The extension stop command of the hydraulic module is controlled by pressure. When the pressure in the cylinder reaches a certain threshold, it is assumed that the electrode has been pushed into place.

[0050] (3) The signal control module issues functional instructions and clicks on the module to start the specific work of power supply / measurement.

[0051] (4) After the test is completed, the hydraulic control module first controls the electrode to retract to its original position, and then the support stepper module reverses and controls the multi-electrode module to retract to its original position. After the entire set of modules is retracted, it moves forward synchronously with the TBM body, and the test process is repeated during the next test.
