Description

Technical Field

[0001] The present invention relates to the technical field of advanced geological drilling, in particular to an intelligent drilling detection device for advanced geological prediction of highway tunnels. Background Art

[0002] A geological drilling rig is a device used for advanced geological exploration in underground projects such as tunnels, mines, and water conservancy projects. Its structural design must balance high strength, stability, adaptability, and intelligence. In traditional tunnel geological drilling, the rig base is typically placed directly on the tunnel floor or secured with simple supports.

[0003] Since the drill rig base does not form an effective connection with the rock mass, the drill rig will generate large axial reaction force and vibration during the drilling process. Especially in geological conditions such as broken zones and soft rocks, the base is prone to sinking, sliding or overturning, resulting in drilling deviation or even drill sticking. Summary of the Invention

[0004] Based on this, it is necessary to provide an intelligent drilling detection device for advanced geological prediction of highway tunnels that can form an effective connection with the rock mass to address the above technical problems.

[0005] The present invention provides an intelligent drilling detection device for advanced geological prediction of highway tunnels, comprising: Drilling rigs, used to obtain geological data ahead; A support base, equipped with a bracket, a walking mechanism and a positioning mechanism, for supporting the drilling rig; a traction member, mounted on the support base, and used to connect the support base to the rock mass in front; The traction member includes a driving member, a traction solenoid, and a traction claw.

[0008] In one embodiment, the outer wall of the traction coil has a spiral groove, and the inner wall of the traction coil has a driving tooth surface.

[0009] In one embodiment, the traction claws have four groups, each of which includes a driving gear disc and a traction rod. The driving gear disc is installed at the end of the traction rod away from the traction coil outlet, and the driving gear disc is engaged with the driving tooth surface and corresponds one to one.

[0010] In one embodiment, the traction claw further includes a bite head, which is mounted on an end of the traction rod adjacent to the outlet of the traction solenoid; Among them, when the four groups of traction claws are in a closed state, the four groups of engaging heads form a complete cone, the bottom diameter of the cone matches the outer diameter of the traction screw, and the bottom surface of the cone abuts against the plane of the outlet end of the traction screw, that is, the bottom of the engaging head is in contact with the plane of the outlet end of the traction screw.

[0011] In one embodiment, the surface of the traction coil abutting against the cone has a driving groove.

[0012] In one embodiment, the engaging head has a movable groove, and when the bottom of the engaging head is in contact with the plane of the outlet end of the traction screw, the movable groove is connected to the driving groove.

[0013] In one embodiment, a pre-occlusal block is installed in the movable groove, and the pre-occlusal block can be displaced in the radial direction of the traction coil in the movable groove, and a contraction spring is installed at the bottom of the pre-occlusal block; Among them, when the bottom of the engaging head is in contact with the plane of the outlet end of the traction screw, the pre-engaging block is squeezed and contracted into the movable groove by the driving groove. When the four groups of traction claws are in an open state, the top end of the pre-engaging block is pushed out of the movable groove by the contraction spring.

[0014] In one embodiment, a dust suction pipe is installed along the axis through the traction screw and the connecting pipe, the dust outlet end of the dust suction pipe passes through the pipe wall of the connecting pipe and extends to the outside, and the dust suction end of the dust suction pipe is located inside the traction screw; The inner end of the traction rod has a limiting slot, and the annular groove body formed by the four groups of limiting slots of the traction rod matches the tube wall shape of the dust suction tube.

The term "and / or" as used in this description includes any and all combinations of one or more of the associated listed items.

[0024] The following combination Figures 1-6 The invention describes an intelligent drilling detection device for advanced geological prediction of a highway tunnel.

[0025] like Figure 1 and Figure 2 As shown, in one embodiment, an intelligent drilling detection device for advanced geological prediction of a highway tunnel includes a drilling rig 100, a support base 200 and a traction member 300.

[0026] The drilling rig 100 is used to obtain front geological data.

[0027] The support base 200 includes a bracket 210 , a traveling mechanism 220 , and a positioning mechanism 230 , and is used to support the drilling rig 100 .

[0028] It should be noted that the walking mechanism 220 is a crawler-type walking wheel, which is a conventional technical means and will not be described in detail here.

[0029] Preferably, since the ground during tunnel excavation is mostly gravel and soil, and the geology is relatively soft, the intelligent drilling detection device will be placed for a long time, which will press down the ground and cause each group of legs to sink to varying degrees, affecting the drilling angle of the drilling rig 100. The positioning mechanism 230 includes electric legs and level sensors. The level sensors are distributed and installed at the four corners of the bracket 210. The level sensors measure the balance state of the bracket 210. When it is detected that one end of the bracket 210 is tilted, the level sensor continuously outputs a signal to the controller of the intelligent drilling detection device. The controller compares the preset threshold, calculates the height difference to be compensated, and outputs an adjustment instruction to the electric legs for adjustment.

[0030] The traction member 300 is installed on the support base 200 and is used to connect the support base 200 to the front rock mass.

[0031] The traction member 300 includes a driving member 310, a traction screw 320 and a traction claw 330. The driving member 310 is installed on the support seat 200. The traction screw 320 is connected to the output end of the driving member 310. The traction claw 330 is installed in the tube body of the traction screw 320 away from the driving member 310. One end of the traction claw 330 is located in the traction screw 320 and engages with the inner wall of the traction screw 320.

[0032] Among them, when the traction screw 320 and the traction claw 330 drill into the front rock, the traction claw 330 is stored in the traction screw 320 in a closed state. When the traction screw 320 and the traction claw 330 pull the support seat 200, the traction claw 330 is in an expanded support state and engages with the inner wall of the front rock.

[0033] Specifically, when the intelligent drilling detection device is used to perform geological prediction measurement for tunnel excavation, after the intelligent drilling detection device reaches the measurement point through the walking mechanism 220, the positioning mechanism 230 fixes the position of the intelligent drilling detection device. At the same time, in order to improve the stability of the operation, the driving member 310 is started, and the driving member 310 drives the traction screw 320 and the traction claw 330 to approach the rock mass while rotating for drilling.

[0034] During drilling, the outer end of the traction claw 330 in the retracted state is tapered, effectively reducing resistance during drilling. Once the traction claw 330 has fully penetrated the rock mass, the driver 310 is activated again, causing the traction solenoid 320 to move linearly away from the rock mass. As the traction solenoid 320 moves, the meshing teeth drive the traction claw 330 outward to its maximum expansion position, thereby expanding and engaging the inner wall of the rock mass. At this point, the traction claw 330 is driven by the traction solenoid 320 to rotate to its maximum angle, maintaining the meshing state between the traction claw 330 and the traction solenoid 320. This stabilizes the overall length of the traction solenoid 320 and traction claw 330, thereby achieving a pulling effect between the support base 200 and the rock mass and helping to maintain the stability of the support base 200.

[0035] like Figure 3 As shown, in one embodiment, the driving member 310 includes a mounting seat 312, a support rail frame 314, a drilling power source 316 and a rotational power source 318. The drilling power source 316 is mounted on the mounting seat 312, and the rotational power source 318 is slidably mounted on the support rail frame 314. The output end of the drilling power source 316 is connected to the rotational power source 318 to drive the rotational power source 318 to move in the horizontal direction.

[0036] It should be noted that the drilling power source 316 may be a hydraulic cylinder.

[0037] In this embodiment, the rotational power source 318 includes a rotational drive motor 311 and a reducer 313. The rotating shaft of the rotational drive motor 311 is connected to the input end of the reducer 313. The rotating rod at the output end of the reducer 313 is installed with a connecting tube 315, and the connecting tube 315 is fixedly connected to the traction screw 320.

[0038] Specifically, when driving the traction screw 320 and the traction claw 330 to drill into the rock mass, the drilling power source 316 drives the rotary power source 318 to move toward the rock mass, thereby driving the traction screw 320 and the traction claw 330 to drill into the rock mass. Simultaneously, the rotary power source 318 drives the connecting tube 315 to rotate via the speed reducer 313, which in turn drives the traction screw 320 and the traction claw 330 to rotate, achieving a rotary drilling effect.

[0039] When driving the traction screw 320 to move outside the rock body, the drilling power source 316 drives the traction screw 320 to move synchronously through the rotation power source 318 and the connecting pipe 315 until the traction claw 330 is driven by the traction screw 320 to rotate to the maximum angle.

[0040] like Figure 4 and Figure 5 As shown, in one embodiment, the outer wall of the traction solenoid 320 has a spiral groove 321 , and the inner wall of the traction solenoid 320 has a driving tooth surface 323 .

[0041] In this embodiment, there are four groups of traction claws 330, which include a driving gear disc 332 and a traction rod 334. The driving gear disc 332 is installed at the end of the traction rod 334 away from the outlet of the traction screw tube 320. The driving gear disc 332 is engaged with the driving tooth surface 323 and corresponds one to one.

[0042] Preferably, in order to improve the stability of the meshing connection between the driving tooth surface 323 and the driving gear disc 332, there are limit baffles on both sides of the driving tooth surface 323. When the driving tooth surface 323 is meshed with the driving gear disc 332, the limit baffles are respectively in contact with the two side surfaces of the driving tooth surface 323.

[0043] It should be further explained that the meshing connection between the driving tooth surface 323 and the driving gear disc 332 limits the relative rotation between the traction solenoid 320 and the traction pawl 330 , thereby enabling the traction solenoid 320 to drive the traction pawl 330 to rotate synchronously.

[0044] In this embodiment, the traction claw 330 further includes an engaging head 336 , which is mounted on an end of the traction rod 334 adjacent to the outlet of the traction solenoid 320 .

[0045] When the four groups of traction claws 330 are in a closed state, the four groups of engaging heads 336 form a complete cone. The bottom diameter of the cone matches the outer diameter of the traction screw 320, and the bottom surface of the cone abuts against the plane of the outlet end of the traction screw 320, that is, the bottom of the engaging head 336 is in contact with the plane of the outlet end of the traction screw 320.

[0046] It should be noted that the surface of the engaging head 336 protruding from the traction rod 334 can effectively increase the friction between the engaging head 336 and the inside of the rock mass when the engaging head 336 is in an expanded state.

[0047] Specifically, when the driving traction screw 320 is displaced outside the rock body, the driving tooth surface 323 drives the driving gear disc 332 to rotate, and the driving gear disc 332 drives the engaging head 336 to rotate synchronously through the traction rod 334 until the traction rod 334 swings outward to abut against the outlet end of the traction screw 320. During this process, the gradual expansion of the engaging head 336 can increase the difficulty of the traction claw to separate from the rock body.

[0048] like Figure 6 As shown, in one embodiment, the surface of the traction solenoid 320 that abuts against the cone has a driving groove 325 .

[0049] In this embodiment, a movable groove 331 is provided on the engaging head 336 . When the bottom of the engaging head 336 is in contact with the plane of the outlet end of the traction screw 320 , the movable groove 331 is communicated with the driving groove 325 .

[0050] In this embodiment, a pre-engagement block 338 is installed in the movable groove 331 . The pre-engagement block 338 can be displaced radially of the traction screw 320 in the movable groove 331 . A contraction spring 333 is installed at the bottom of the pre-engagement block 338 .

[0051] When the bottom of the engaging head 336 is in contact with the flat surface of the outlet of the traction solenoid 320, the pre-engaging block 338 is squeezed and retracted into the movable groove 331 by the driving groove 325. When the four sets of traction claws 330 are in an open state, the top of the pre-engaging block 338 is pushed out of the movable groove 331 by the retraction spring 333.

[0052] Preferably, since soil will enter the movable groove 331 when the engaging head 336 drills into the rock mass, the bottom end of the movable groove 331 is a through structure, so that when the traction claw 330 expands, the soil in the movable groove 331 can be discharged, reducing the impact of excessive soil accumulation in the movable groove 331 on the popping out of the pre-engaging block 338.

[0053] Specifically, when the traction screw 320 is driven to move toward the outer wall of the rock body, the driving groove 325 on the traction screw 320 is separated from the pre-bite block 338, the pre-bite block 338 is released from the limit, and the pre-bite block 338 is pushed by the contraction spring 333 to move along the movable groove 331, so that the top end of the pre-bite block 338 is pushed out of the movable groove 331, and the end of the pre-bite block 338 extending out of the movable groove 331 abuts against the inner wall of the rock body, thereby increasing the friction surface between the biting head 336 and the inner wall of the rock body.

[0054] In this embodiment, a dust suction pipe 317 is installed along the axis through the traction screw pipe 320 and the connecting pipe 315. The dust outlet end of the dust suction pipe 317 extends to the outside through the pipe wall of the connecting pipe 315, and the dust suction end of the dust suction pipe 317 is located inside the traction screw pipe 320.

[0055] It should be noted that the dust suction pipe is connected to an external vacuum cleaner to suck out the dust that falls into the traction claw 330 .

[0056] Preferably, in order to facilitate the suction of dust between the traction claws 330 , dust suction channels are provided on the traction rod 334 and the engaging head 336 to increase the dust discharge path.

[0057] The inner end of the traction rod 334 has a limiting slot 401. The annular groove body formed by the limiting slots 401 of the four groups of traction rods 334 matches the tube wall shape of the dust suction tube 317. The connecting tube 315 has a movable channel 402, and the dust suction tube 317 is moved into or out of the limiting slot 401 by moving along the movable channel 402.

[0058] Specifically, when the traction claw 330 is driven to expand outward, the dust suction tube 317 is moved out of the limiting slot 401 , thereby releasing the angle limiting effect on the traction rod 334 .

[0059] When moving the traction claw 330 out of the rock mass, it is necessary to retract the traction claw 330 into the traction screw tube 320, connect the dust outlet end of the dust suction tube 317 to the negative pressure end of the vacuum cleaner, start the vacuum cleaner, and then suck out the dust between the traction claws 330, so that the traction claw 330 can be rotated inward and assembled to the initial state, and then retracted back into the traction screw tube 320, and the drilling power source 316 is started to drive the traction screw tube 320 to move toward the inner wall of the rock mass, so that the traction screw tube 320 is again in contact with the plane of the bite head 336, and at this time, the dust suction tube 317 is moved to be stuck in the limit slot 401, so that the traction claw 330 remains in a closed state.

[0060] When the traction claw 330 is driven to move out of the rock mass, the driving tooth surface 323 on the traction screw 320 drives the driving disk 332 to move synchronously, and the driving disk 332 drives the biting head 336 to move synchronously through the traction rod 334, thereby moving the traction claw 330 out of the rock mass.

[0061] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above-described embodiments merely illustrate several embodiments of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of the present invention. Therefore, the scope of the present invention shall be determined by the appended claims.
