Two pairs of first through holes 1-1 and second through holes 1-2 are arranged on the upper surface of the vehicle frame 1 for the installation and assembly of the first telescopic bracket 2 and the second telescopic bracket 3. A square opening 1-3 is opened on the lower surface of the vehicle frame 1 for the transmission track 15 to pass through. A third through hole 1-4 is arranged on the side surface of the vehicle frame 1 for the lead wire of the signal receiver 19 to pass through.

[0050] like Figure 3As shown, the first telescopic bracket 2 and the second telescopic bracket 3 have the same structure, both including a support frame 2-1, a spring 2-2, and a spring fixing shell 2-3. The crossbeam of the support frame 2-1 is used to house the first roller 4 and the second roller 5. The two ends of the crossbeam are slightly protruding to limit the movement of the rollers. The two columns of the support frame 2-1 have protrusions at both ends and in the middle. The protrusions at the ends are to prevent the support frame 2-1 from falling off the spring fixing shell 2-3, and the protrusions in the middle are used to fix the spring 2-2. The spring fixing shell 2-3 is a hollow cylinder with a diameter larger than the protrusion in the middle of the column of the support frame 2-1. The top openings of the two spring fixing shells 2-3 are connected and fixed to the first through hole 1-1 and the second through hole 1-2 on the upper surface of the vehicle frame 1. The bottom of the spring fixing shell 2-3 has a hole through which the column of the support frame 2-1 can pass. One end of the spring 2-2 is fixed to the protrusion in the middle of the column leg of the support frame 2-1, and the other end is fixed to the bottom of the spring fixing shell 2-3.

[0051] like Figure 1 As shown, the surfaces of the first vertical roller 4 and the second vertical roller 5 are provided with anti-slip patterns and have a round hole in the middle. The rollers are placed on the first telescopic bracket 2 and the second telescopic bracket 3 through the round hole.

[0052] like Figure 4 As shown, the first lateral roller 6 and the second lateral roller 7 have the same structure, both including a fixed bracket 6-2 and a straight column roller 6-1. The first lateral roller 6 and the second lateral roller 7 are respectively fixed on both sides of the side surface of the vehicle frame 1 near the web of the steel arch frame 22.

[0053] like Figure 1 , 9 As shown in Figure 10, the magnet 8 is fixed in the middle of the side surface of the vehicle frame 1, that is, between the first lateral roller 6 and the second lateral roller 7. Its main function is to attach the cable laying vehicle to the web of the steel arch frame 22 in a non-contact manner, so as to prevent the cable laying vehicle from falling off the steel arch frame 22 during use.

[0054] like Figure 5 As shown, the cable locking bracket 9 is fixed to the left side surface of the vehicle frame 1, and includes multiple locking slots 9-1 and matching fasteners 9-2. The sidewalls of the locking slots 9-1 have opposing circular holes for mounting the fasteners 9-2; the short side of the fastener 9-2 has an arc-shaped opening, and a cylindrical pivot is provided at the intersection of the long and short sides. The fastener 9-2 is mounted on the circular holes in the sidewalls of the slots 9-1 via the pivot and can rotate freely.

[0055] like Figure 6As shown, the first track bracket 10 and the second track bracket 11 are U-shaped. The first track bracket 10 is fixed to the bottom of the vehicle frame 1 near the square opening 1-3 and is used to mount the drive sprocket 12; the second track bracket 11 is fixed to the bottom of the vehicle frame 1 away from the square opening 1-3 and is used to mount the idler wheel 13.

[0056] like Figure 7 As shown, the drive sprocket 12 is a double gear, with the first linkage tooth 12-1 meshing with the moving track 14 and the second linkage tooth 12-2 meshing with the transmission track 15.

[0057] like Figure 1 , 9 As shown in Figures 1 and 10, the diameter and number of teeth of the inducer wheel 13 and the first linkage tooth 12-1 are the same. The inducer wheel 13 and the drive sprocket 12 form the moving parts of the cable laying vehicle through the track 14.

[0058] like Figure 1 , 9 As shown in Figures 10 and 10, the inner side of the track 14 has a toothed structure that can mesh with the drive sprocket 12 and the idler wheel 13, and the outer side of the track 14 has an anti-slip rubber layer.

[0059] like Figure 1 , 9 As shown in Figure 10, the inner side of the transmission track 15 has a toothed structure, which meshes with the second linkage tooth 12-2 and the gear of the servo motor 16. The transmission track 15 transmits the power of the servo motor 16 to the drive sprocket 12.

[0060] like Figure 1 , 9 As shown in Figure 10, the servo motor 16 provides power to the cable laying vehicle. The servo motor 16, switch 17, controller 18, and power supply 20 are all located inside the vehicle frame 1.

[0062] A method for using a sensor external cable laying vehicle for underground engineering monitoring includes the following steps:

[0063] 1) Install the sensor external cable: First, lift the buckle 9-2, put the end of the sensor external cable 23 into the locking groove 9-1 of the cable locking bracket 9, and press the buckle 9-2 to make the sensor external cable 23 securely locked in the locking groove 9-1.

[0064] 2) Install the cable laying vehicle: Install the cable laying vehicle near the bottom of the steel arch 22. Press down the first telescopic bracket 2 and the second telescopic bracket 3 so that the cable laying vehicle can be smoothly placed into the groove of the I-beam arch 22. Position the magnet 8 of the cable laying vehicle with one side facing the web of the I-beam arch 22. The first lateral roller 6 and the second lateral roller 7 should contact the web of the I-beam arch 22, and the magnet 8 of the cable laying vehicle should generate a strong attraction with the web of the I-beam arch 22. Release the first telescopic bracket 2 and the second telescopic bracket 3 so that the first vertical roller 4 and the second vertical roller 5 of the cable laying vehicle contact the upper flange of the I-beam arch 22, and the moving track 14 contacts the lower flange of the I-beam arch 22.

[0065] 3) Laying external cables: Turn on the switch 17 of the cable laying vehicle, use the remote control 21 to control the cable laying vehicle to move along the web of the I-beam arch 22, and lay the external cables along the web of the I-beam arch to the installed sensor pin lines.

[0066] 4) Connect the external cable to the sensor pin: Lift the buckle 9-2, take out the required external sensor cable 23 from the locking groove 9-1 of the cable locking position, and connect it to the sensor pin.

[0067] 5) Dismantle the cable laying vehicle: After all the external cables of the sensors have been laid in place, control the cable laying vehicle to return to the bottom of the I-beam arch and turn off the switch 17 on the cable laying vehicle; compress the first telescopic bracket 2 and the second telescopic bracket 3 of the cable laying vehicle and forcefully remove the cable laying vehicle from the I-beam arch.
