[0026] The drilling probe comprises a drill rod 1 and a drill bit 2 installed on the right side of the drill rod 1, and the outer side of the drill rod 1 is provided with a subassembly 3.

[0027] The subassembly 3 comprises a subassembly ring 31, the left side of the subassembly ring 31 is rotationally connected with a fixed claw 32, the side close to the drill rod 1 of the fixed claw 32 is rotationally connected with a claw foot 33, the left side of the fixed claw 32 is fixedly connected with a structure frame 34, the bottom of the structure frame 34 is fixedly connected with a contact cylinder 35, and the side close to the drill rod 1 of the contact cylinder 35 is installed with a stress sensor probe 36.

[0028] The right side of the subassembly ring 31 is fixedly connected with a tension ring 4, the left side of the tension ring 4 is fixedly connected with a connecting frame 5, the inner side of the left side of the connecting frame 5 is fixedly connected with a push ring 6, and the surface of the push ring 6 is in contact with the fixed claw 32.

[0029] In the embodiment, the drill pipe 1 and the drill bit 2 are arranged to cooperate with the drilling machine to perform the drilling operation, and the auxiliary assembly 3 can facilitate the installation of the stress sensor probe 36 on the surface of the drill pipe 1. Since the drill pipe 1 and the drill bit 2 are connected, the stress generated by the drill bit 2 during the drilling process can be indirectly transmitted to the drill pipe 1 and detected by the stress sensor probe 36, and then transmitted to the stress sensor. When the drill bit 2 is damaged or collides with the cable and the pipeline, the stress will change, and at this time, the machine can be stopped in time for processing, effectively preventing the drill bit 2 from damaging the underground pipeline and cable. When the stress sensor probe 36 is disassembled or the position thereof is adjusted, the tension ring 4 can be horizontally moved relative to the auxiliary ring 31, the connecting frame 5 connected thereto pushes the fixed jaw 32, and the fixed jaw 32 rotates along the auxiliary ring 31 to be opened when the fixed jaw 32 is pushed from the inside. At this time, the stress sensor probe 36 connected through the contact cylinder 35 is also opened, and at this time, the entire auxiliary assembly 3 can be removed from the outside of the drill pipe 1 or the position thereof is adjusted, thereby improving the flexibility of the structure in use.

[0030] Specifically, as shown in Figure 5 , the left side of the auxiliary ring 31 is fixedly connected with the rotating shaft 7, the inner side of the rotating shaft 7 is fixedly connected with the fixed jaw 32, the outer side of the fixed jaw 32 is fixedly connected with the hard torsional spring 8, and the side close to the rotating shaft 7 of the hard torsional spring 8 is fixedly connected with the rotating shaft 7.

[0031] Specifically, as shown in Figure 2 , the bottom of the claw foot 33 is provided with a non-slip pad, and the surface of the non-slip pad is provided with a non-slip pattern.

[0032] Specifically, as shown in Figure 4 , the inner side of the tension ring 4 is slidably connected with the limiting rod 9, the side close to the auxiliary ring 31 of the limiting rod 9 is fixedly connected with the auxiliary ring 31, and the outer side of the limiting rod 9 is sleeved with the pressing spring 10.

[0033] In the embodiment, the rotating shaft 7 cooperates with the fixed jaw 32, which can facilitate the rotation of the fixed jaw 32 along the left side of the auxiliary ring 31 through the rotating shaft 7. The hard torsional spring 8 can always make the fixed jaw 32 force close to the surface of the drill pipe 1. The non-slip pad can reduce the probability of slipping between structures when the claw foot 33 is subjected to the force of the fixed jaw 32 and is attached to the surface of the drill pipe 1. The limiting rod 9 cooperates with the pressing spring 10, which can limit the movement position of the tension ring 4 and make the tension ring 4 slide along the limiting rod 9. The pressing spring 10 can keep resetting when it is not affected by external force, thereby avoiding affecting the normal operation of the fixed jaw 32.

[0034] Specifically, as shown in Figure 4As shown, the left side of the auxiliary ring 31 is provided with a first side piece 11, the right side of the tension ring 4 is provided with a second side piece 12, the inner side of the second side piece 12 is threadedly connected with a screw rod 13, and the side of the screw rod 13 close to the first side piece 11 is rotationally connected with the first side piece 11.

[0035] In the embodiment, by setting the first side piece 11 to cooperate with the second side piece 12, when the auxiliary assembly 3 is disassembled, the auxiliary ring 31 and the tension ring 4 need to be relatively moved, so that the second side piece 12 is close to the first side piece 11 by rotating the screw rod 13, at this time, the spring 10 is pressed outwardly, so that the structure will not fall off, and the distance between the first side piece 11 and the second side piece 12 is reduced under the clamping of the second side piece 12 and the first side piece 11, so that the entire auxiliary assembly 3 can be conveniently moved, and when the auxiliary assembly 3 is fixed outside the drill rod 1, the first side piece 11 and the second side piece 12 can also be removed to avoid normal drilling work.

[0036] Specifically, as shown in the figure, Figure 3 The inner side of the contact cylinder 35 is fixedly connected with a partition plate 14, the inner side of the contact cylinder 35 is slidingly connected with a buffer block 15, the buffer block 15 is made of rubber material, the bottom of the buffer block 15 is fixedly connected with a bottom rod 16, the bottom of the bottom rod 16 is fixedly connected with the top of the stress sensor probe 36, and the inner side of the contact cylinder 35 is filled with fluid medium

[0037] Specifically, as shown in the figure, Figure 3 The top of the buffer block 15 is fixedly connected with a return spring 17, and the top of the return spring 17 is fixedly connected with the contact cylinder 35.

[0038] Specifically, as shown in the figure, Figure 3 The outer side of the bottom rod 16 is provided with a sealing element, and the top and bottom of the inner side of the partition plate 14 are both provided with a flow hole 18.

[0039] In the embodiment, by setting the partition plate 14, the space inside the contact cylinder 35 is divided, when the contact cylinder 35 is pressed to make the stress sensor probe 36 contact with the surface of the drill rod 1, the stress sensor probe 36 is stressed, and the bottom rod 16 connected therewith and the buffer block 15 are pushed to move inside the contact cylinder 35, so as to compensate the distance between the stress sensor probe 36 and the drill rod 1, and when normal operation, if larger vibration or impact occurs, the bottom rod 16 and the buffer block 15 push the internal fluid to flow along the flow hole 18, so as to achieve the effect of fluid damping and buffering.

[0040] Working principle: when drilling, first install the auxiliary assembly 3 on the outside of the drill pipe 1, rotate the screw 13 to make the second side piece 12 close to the first side piece 11, make the pressing spring 10 stressed, fix the relative position of the auxiliary assembly 31 and the tension ring 4. Then, move the tension ring 4 horizontally, open the fixed jaw 32 through the connecting frame 5 and the pushing ring 6, after the auxiliary assembly 3 is sleeved on the drill pipe 1 in the appropriate position, loosen the tension ring 4, use the hard torsional spring 8 to make the fixed jaw 32 close to the drill pipe 1, make the bottom anti-skid pad of the jaw foot 33 adhere to the drill pipe 1, if it is necessary to adjust the position of the stress sensor probe 36, repeat the operation of opening the fixed jaw 32, and remove the first side piece 11 and the second side piece 12 during operation, fix the probe after adjustment by restoring the position of the tension ring 4, then, the drill pipe 1 and the drill bit 2 cooperate with the drilling machine to work, the stress sensor probe 36 detects the stress generated by the drill bit 2 and conducted to the drill pipe 1, once the stress changes, stop working in time to prevent damage to underground facilities, at the same time, the buffer structure in the contact cylinder 35 plays a buffering role during operation.

[0041] The above is only a preferred embodiment of the present application, and is not intended to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
