Description

Technical Field

[0001] This application belongs to the field of geotechnical engineering technology, specifically relating to a drill rod verticality detection device for geotechnical engineering drilling construction. Background Technology

[0002] Drilling is an indispensable key technology in geotechnical engineering, mainly used in geological exploration, foundation design, construction monitoring, and disaster prevention. During drilling, the drill rod is the core transmission component. Specifically, the drill rod is connected to the drilling rig (such as a rotary drilling rig or impact drilling rig) at the top, transmitting torque and axial pressure to the drill bit to cut, break, or impact the soil and rock layers to form a borehole.

[0003] In the existing technology, in order to ensure the perpendicularity of the borehole axis and the working face, the verticality detection of the drill rod is very important. The common method of drill rod verticality detection is to use an inclination sensor mounted on the drilling rig. The inclination sensor detects the angle between the drilling rig and the working face in real time to obtain the verticality of the drill rod.

[0004] The inventors discovered that under special circumstances, such as aging or damage at the connection between the drill rod and the drilling rig, the angle between the drill rod and the drilling rig will change. In this case, the result of the tilt sensor cannot directly reflect the verticality of the drill rod, affecting the reliability of the drill rod verticality detection result. Utility Model Content

[0005] This application provides a drill rod verticality detection device for geotechnical engineering drilling construction, which aims to detect the verticality of the drill rod relative to the construction surface in real time and ensure the reliability of the detection results.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0008] The base is used to fix it on the construction surface, and it has positioning holes for being coaxial with the drill hole;

[0009] A slide table is disposed on the side of the base facing away from the construction surface; the slide table has a degree of freedom to move around the positioning hole, and the slide table is connected to a driving component.

[0010] A slider, slidably connected to the slide platform and having an elastic element between it and the slide platform, is adapted to move the slider toward the central axis of the positioning hole; the slider has a probe extending toward the central axis of the positioning hole, and the extended end of the probe is used to abut against the outer peripheral wall of the drill rod; and

[0011] A ranging component is fixedly mounted on the slide platform, with its orientation parallel to the sliding direction of the slider and the ranging component facing the slider, to detect the moving distance of the slider.

[0012] In one possible implementation, a support cylinder coaxially arranged with the positioning hole is fixedly connected to the base, and the slide is slidably connected to the end face of the support cylinder facing away from the base.

[0013] In one possible implementation, the driving component includes:

[0014] A driven gear is coaxially sleeved on the outer circumference of the support cylinder and rotatably connected to the support cylinder; the driven gear is also fixedly connected to the slide table to drive the slide table to move around the central axis of the support cylinder; and

[0015] A rotating motor is fixedly mounted on the base, with its power output axis parallel to the axis of the driven gear, and a driving gear that meshes with the driven gear is fixedly connected to the power output end of the rotating motor.

[0016] In one possible implementation, the driven gear further includes:

[0017] A collar is coaxially sleeved on the outer circumference of the support cylinder and located between the driven gear and the slide table;

[0018] The collar is detachably connected to the slide, and the collar has a threaded groove on the side facing the driven gear; the driven gear has a through hole adapted to coaxially communicate with the threaded groove, and a connecting bolt adapted to pass through the through hole and be threadedly connected to the threaded groove.

[0019] In one possible implementation, the end face of the support cylinder facing away from the base is provided with an annular groove coaxially arranged therewith, and a connector is slidably embedded in the annular groove;

[0020] The connecting member is rotatably connected to the slide, and its rotation axis is parallel to the axis of the support cylinder. The connecting member has a degree of freedom to rotate relative to the support cylinder about its own central axis.

[0021] In one possible implementation, the slide has a guide shaft fixedly connected to it and extending toward the central axis of the positioning hole; the slider is slidably connected to the guide shaft, and the elastic element is a spring sleeved on the guide shaft;

[0022] The spring is located on the side of the slider facing away from the central axis of the positioning hole and is in an elastically compressed state, so as to drive the slider to move toward the central axis of the positioning hole.

[0023] In one possible implementation, the ranging component is an infrared ranging sensor fixedly connected to the slide; the infrared ranging sensor is located on the side of the slider facing away from the central axis of the positioning hole and is oriented towards the central axis of the positioning hole.

[0024] In one possible implementation, the extended end of the probe rod is provided with a concave ball groove, and a ball bearing for abutting against the outer circumferential surface of the drill rod is embedded in the concave ball groove.

Based on this, the elastic element can drive the slider to move towards the drill rod inserted into the drill hole, so that the extension end of the probe rod abuts against the outer circumferential surface of the drill rod. At this time, by driving the slide table to move around the drill rod by the driving component, the probe rod can slide along the outer circumferential surface of the drill rod. If the verticality of the drill rod changes (i.e., the drill rod tilts), the reading of the distance measuring component will change; if the verticality of the drill rod does not change, the reading of the distance measuring component will not change.

[0028] The drill rod verticality detection device for geotechnical engineering drilling construction provided in this embodiment, compared with the prior art, can use the reading of the distance measuring component to provide real-time feedback on whether the drill rod is tilted by driving the probe rod to move around the drill rod, so as to achieve the technical purpose of detecting the verticality of the drill rod relative to the construction surface. Furthermore, due to the overlap of the base and the construction surface and the driving action of the slider on the elastic element, the reliability of the aforementioned detection results is effectively guaranteed.

[0045] Please refer to the following: Figures 1 to 10 The verticality detection device for drill rods used in geotechnical engineering drilling construction provided in this application will now be described. The verticality detection device for drill rods used in geotechnical engineering drilling construction proposed in this application includes a base 1, a sliding table 2, a slider 3, and a distance measuring component 4.

[0046] The base 1 is used to fix it on the construction surface, and the base 1 is provided with a positioning hole 11 for being coaxial with the drill hole.

[0047] The slide 2 is located on the side of the base 1 facing away from the construction surface. Specifically, when the base 1 is fixed to the construction surface, the slide 2 is located on the side of the base 1 facing away from the construction surface, and there is a gap between it and the outer side of the base 1. After assembly, the slide 2 has the freedom to move around the positioning hole 11, and the slide 2 is connected to a drive component 5 for driving it to move along a preset trajectory.

[0048] The slider 3 is slidably connected to the slide table 2, and its sliding direction is parallel to the direction of the slide table 2 toward the central axis of the positioning hole 11. In this embodiment, the slide table 2 adopts a track shape extending toward the central axis of the positioning hole 11 to limit the movement trajectory of the slider 3. There is an elastic element 6 between the slider 3 and the slide table 2. In actual use, the elastic element 6 can drive the slider 3 to move toward the central axis of the positioning hole 11.

[0049] The slider 3 has a probe 7 fixedly connected to it, and the probe 7 extends toward the central axis of the positioning hole 11 so that the extended end of the probe 7 is used to abut against the outer peripheral wall of the drill rod.

[0050] The ranging component 4 is fixedly mounted on the slide table 2, with its orientation parallel to the sliding direction of the slider 3, and the ranging component 4 is positioned towards the slider 3 to detect the moving distance of the slider 3 on the preset moving trajectory.

[0051] In this embodiment, the device is fixed by fixing the base 1 to the construction surface and making the positioning hole 11 and the drill hole coaxial. Based on this, the elastic member 6 can drive the slider 3 to move toward the drill rod inserted into the drill hole, so that the extension end of the probe 7 abuts against the outer circumferential surface of the drill rod. At this time, the drive member 5 drives the slide table 2 to move around the drill rod, so that the probe 7 can slide along the outer circumferential surface of the drill rod. If the verticality of the drill rod changes (i.e., the drill rod tilts), the reading of the distance measuring member 4 will change; if the verticality of the drill rod does not change, the reading of the distance measuring member 4 will not change.

[0052] The drill rod verticality detection device for geotechnical engineering drilling construction provided in this embodiment, compared with the prior art, can use the reading of the distance measuring component 4 to provide real-time feedback on whether the drill rod is tilted by driving the probe rod 7 to move around the drill rod, so as to achieve the technical purpose of detecting the verticality of the drill rod relative to the construction surface. Furthermore, due to the overlap of the base 1 and the construction surface and the driving action of the slider 3 on the elastic element 6, the reliability of the aforementioned detection results is effectively guaranteed.

[0053] In some embodiments, such as Figure 2 , Figure 7 and Figure 10 As shown, a support cylinder 10 coaxially arranged with the positioning hole 11 is fixedly connected to the base 1. Specifically, the support cylinder 10 is fixedly connected to the base 1, and the central axis of the support cylinder 10 coincides with the central axis of the positioning hole 11.

[0054] The slide 2 is slidably connected to the end face of the support cylinder 10 facing away from the base 1, so as to fix the slide 2 to the outside of the base 1 and to slide it to the base 1.

[0055] In some embodiments, such as Figure 2 and Figure 5 As shown, the driving component 5 includes a driven gear 51 and a rotating motor 52.

[0056] Driven gear 51 is coaxially sleeved on the outer periphery of support cylinder 10 and rotatably connected to support cylinder 10; based on this, driven gear 51 is also fixedly connected to slide 2 so that when driven gear 51 rotates, it can drive slide 2 to move synchronously around the central axis of support cylinder 10.

[0057] The rotating motor 52 is fixedly mounted on the base 1, and its power output axis is parallel to the axis of the driven gear 51. The power output end of the rotating motor 52 is fixedly connected to the driving gear 521 that meshes with the driven gear 51.

[0058] By adopting the above technical solution, when the rotating motor 52 is started, the driving gear 521 drives the driven gear 51 to rotate, thereby driving the slide table 2 to move.

[0059] In some embodiments, such as Figure 5 and Figure 9 As shown, the driven gear 51 also includes a collar 8.

[0060] The collar 8 is coaxially fitted around the outer periphery of the support cylinder 10 and is located between the driven gear 51 and the slide table 2.

[0061] The collar 8 is detachably connected to the slide 2; such as Figure 4 As shown, the collar 8 has a snap-fit ​​groove on its side facing the slide table 2, and a connecting rod made of elastic material is fixedly installed on the slide table 2 to fit into the snap-fit ​​groove, so as to realize the detachable connection between the collar 8 and the slide table 2.

[0062] The collar 8 has a threaded groove 81 on the side facing the driven gear 51; the driven gear 51 has a through hole 511 adapted to coaxially communicate with the threaded groove 81, and a connecting bolt 512 adapted to pass through the through hole 511 and be threadedly connected to the threaded groove 81, so as to realize the detachable connection between the collar 8 and the driven gear 51.

[0063] In some embodiments, such as Figure 5 , Figure 7 and Figure 10 As shown, an annular groove 101 is provided on the end face of the support cylinder 10 facing away from the base 1, and a connector 9 is slidably embedded in the annular groove 101, and the connector 9 can move along the length direction of the annular groove 101 in an annular trajectory.

[0064] In order to achieve a sliding connection between the slide table 2 and the support cylinder 10, the aforementioned connecting member 9 is rotatably connected to the slide table 2, and its rotation axis is parallel to the axis of the support cylinder 10. The connecting member 9 has a degree of freedom to rotate relative to the support cylinder 10 about its own central axis.

[0065] In actual use, the slide 2 can slide along the circumference of the support cylinder 10; during the sliding process of the slide 2, the connecting piece 9 can rotate to optimize the sliding effect of the slide 2.

[0066] In some embodiments, such as Figure 6As shown, the slide 2 has a guide shaft 21, which is fixedly connected to the slide 2 by means of a protrusion at the end of the slide 2, and the axial direction of each guide shaft 21 is parallel to the direction of the slide 2 toward the central axis of the positioning hole 11.

[0067] The aforementioned slider 3 is slidably connected to the guide shaft 21, and the elastic element 6 is a spring sleeved on the guide shaft 21. Furthermore, the spring is located on the side of the slider 3 facing away from the central axis of the positioning hole 11, and the two ends of the spring are respectively connected to the slider 3 and the slide table 2. In actual use, the spring is in an elastic compression state to facilitate the movement of the slider 3 toward the central axis of the positioning hole 11, thereby ensuring that the probe rod 7 abuts against the drill rod.

[0068] In some embodiments, such as Figures 4 to 6 As shown, the ranging component 4 is an infrared ranging sensor fixedly connected to the slide table 2.

[0069] In this embodiment, the infrared ranging sensor is located on the side of the slider 3 facing away from the central axis of the positioning hole 11 and is positioned towards the central axis of the positioning hole 11, so that the reading of the infrared ranging sensor changes when the slider 3 moves.

[0070] In some embodiments, such as Figure 8 As shown, the extended end of the probe rod 7 is provided with a concave ball groove 71, and a ball 72 for abutting against the outer circumferential surface of the drill rod is embedded in the concave ball groove 71. This ball 72 can roll relative to the probe rod 7 and will not detach from the concave ball groove 71.

[0071] Compared to the method of the probe rod 7 abutting against the drill rod, the method of abutting the drill rod by the ball bearing 72 can change the line contact to point contact, thereby reducing the friction between the extended end face of the probe rod 7 and the outer peripheral surface of the drill rod, and ensuring the smooth movement of the probe rod 7 around the drill rod.

[0072] In some embodiments, such as Figure 10 As shown, a reserved hole 12 is provided on the base 1, and a reinforcing pile 13 for inserting into the construction surface is slidably inserted into the reserved hole 12 to enhance the fixing effect of the base 1 relative to the construction surface.

[0073] It should be further noted that, in this embodiment, to ensure the stability of the movement of the reinforcing pile 13, a guide cylinder coaxially connected to the reserved hole 12 is also fixedly installed on the base 1; the reinforcing pile 13 is slidably inserted into this guide cylinder so that after it is inserted into the construction surface, the head of the reinforcing pile 13 can abut against the outer end face of the guide cylinder. Furthermore, the diameter of the head of the reinforcing pile 13 is larger than the outer diameter of the guide cylinder, that is, the outer edge of the head of the reinforcing pile 13 is located outside the guide cylinder, so as to facilitate the removal of the reinforcing pile 13 during actual use.

[0074] In some embodiments, such as Figure 1As shown, the base 1 has two handles 14 on the side facing away from the construction surface. The two handles 14 are fixedly installed on both sides of the slide table 2 and are fixedly connected to the slide table 2 so as to facilitate manual handling and control.

[0075] The above content is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
