Description

Technical Field

[0001] The present invention relates to the technical field of drilling equipment, and in particular to a drilling device for intelligent construction. Background Art

[0002] Intelligent construction refers to the use of advanced information technology, automation technology, and data science to optimize the planning, design, construction, and operation management of construction projects. Most of the devices used in intelligent construction are equipped with sensors to collect data during the working process and control the device according to the data, improving the construction quality and efficiency.

[0003] During the process of determining the location of a mine, detailed geological exploration is required to accurately locate the position and scale of the ore body. Therefore, intelligent drilling devices play an important role in this process. Intelligent drilling devices are usually equipped with sensors at the drill bit. When the drill bit of the intelligent drilling device moves downward to drill a hole, the underground abnormal area, that is, the area where the surrounding magnetism and conductivity change caused by the ore body, is detected by the sensor to achieve the detection of the ore body position.

[0004] However, when the existing drilling equipment works in the soil layer, the hole formed by the drill bit during the downward movement is smaller than the hole drilled by the spiral blade on the drilling equipment, resulting in continuous friction between the spiral blade near the drill bit and the soil layer, accelerating the wear of this part of the spiral blade and affecting the overall service life of the spiral blade. Moreover, when the spiral blade moves downward to drill a hole, it will lift the soil around the hole excessively upward, which is likely to cause a decrease in the compactness of the soil around the hole and affect the stability of the foundation of the subsequent mine. Summary of the Invention

[0005] In order to overcome the shortcomings that when the existing drilling equipment drills a hole in the soil layer, the spiral blade near the drill bit continuously rubs against the soil layer, causing wear and affecting the overall service life of the spiral blade, and the spiral blade is likely to cause a decrease in the compactness of the nearby soil, the present invention provides a drilling device for intelligent construction.

[0042] 3.

Detailed implementation manners

[0055] The present invention will be specifically described below with reference to the attached drawings, and the description will be made taking the Figure 2 shown orientation as an example.

[0056] Embodiment 1: A drilling device for intelligent construction, as Figures 1 - 7 shown, includes: a moving vehicle frame 1, the moving vehicle frame 1 is provided with a driving member 101; a first drill rod 2, arranged on the driving member 101, the first drill rod 2 is fixedly connected with a spiral blade, the first drill rod 2 is detachably connected with a second drill rod 3, and the second drill rod 3 is provided with a circular through hole; a drill bit 4, slidably and rotatably connected to the second drill rod 3; a rotating block 5, rotatably connected to the second drill rod 3, the rotating block 5 is slidably connected with a T-shaped plate 6, the T-shaped plate 6 is rotatably connected with a rotating disk 7, and the inclination direction of the rotating disk 7 is the same as the inclination direction of the spiral blade on the first drill rod 2; a rotating assembly, arranged on the T-shaped plate 6, and the rotating assembly adjusts the inclination angle of the rotating disk 7 according to the hardness of the drilling location; a moving assembly, arranged on the T-shaped plate 6, and the moving assembly adjusts the extending length of the rotating disk 7 according to the hardness of the drilling location.

[0057] In the above solution, the driving member 101 is composed of a hydraulic rod, a swing rod, a motor, and a slide rail. An operating platform is provided on the moving vehicle frame 1 for controlling the rotation of the output shaft of the motor on the driving member 101 and the movement of the slide rail. An annular groove is formed on the lower side of the second drill rod 3, and the drill bit 4 is provided with a sensor for sensing the presence of the ore body. Its specific structure is not shown in the figure. An inclined angle is provided at the lower part of the second drill rod 3 for scraping impurities on the outer side surface of the drill bit 4 when the drill bit 4 moves upward. The number of rotating blocks 5 is two (here, the number of subsequent parts is not specifically limited, only for facilitating the understanding of the drawings and text). They are symmetrically distributed about the center of the second drill rod 3. The rotating disk 7 is provided with a number of protrusions distributed at intervals for crushing the soil during rotation. The inclination direction of the rotating disk 7 is the same as that of the spiral blade on the first drill rod 2 for lifting the soil upward and reducing the resistance when the rotating disk 7 moves downward. The number of rotating components is two, which are respectively located on adjacent T-shaped plates 6, and the number of moving components is two, which are respectively located on adjacent T-shaped plates 6.

[0058] As Figures 6 - 9 shown, the rotating component includes: a sleeve 901 disposed in the circular through hole of the second drill rod 3. The sleeve 901 is fixedly connected with a rack frame 902, and the rack frame 902 is fixedly connected with a rectangular block 903; a telescopic rod 904 fixedly connected to the T-shaped plate 6. The telescopic part of the telescopic rod 904 is fixedly connected with a first fixing plate 905, and the first fixing plate 905 is fixedly connected with a gear 906 for meshing with the rack frame 902; a limiting block 907 fixedly connected to the gear 906, and the rectangular block 903 is used for limiting the limiting block 907; an L-shaped plate 908 fixedly connected to the inner wall of the circular through hole of the second drill rod 3, and the L-shaped plate 908 is rotatably connected with the first fixing plate 905; a connecting component disposed on the drill bit 4 for changing the movement mode of the drill bit 4 according to the hardness of the drilling location.

[0059] In the above solution, the number of the rack frames 902 is two, which are symmetrically distributed on both sides of the sleeve 901. The number of the telescopic rods 904 is two for enhancing the stability when the first fixing plate 905 rotates. The number of the limiting blocks 907 is two. The distance between the two limiting blocks 907 is equal to the width of the rectangular block 903, and the rectangular block 903 limits the two limiting blocks 907 in the initial position to ensure that the gear 906 does not rotate. When the rectangular block 903 releases the limitation on the two limiting blocks 907, the gear 906 meshes with the rack frame 902. The cross-sectional shape of the limiting block 907 is semi-circular, and both sides where the arc surface of the limiting block 907 intersects with the horizontal plane are provided with inclined surfaces to facilitate the movement of the rectangular block 903 between the two limiting blocks 907.

[0060] As Figures 4 - 8 、 Figure 10 and Figure 11As shown in the figure, the connecting component includes: a fixing rod 1001 fixedly connected to the drill bit 4, a sleeve 901 rotatably connected to the fixing rod 1001, and the fixing rod 1001 is fixedly connected with a first limiting ring 1002 and a second limiting ring 1003; a limiting plate 1004 fixedly connected to the circular through hole of the second drill rod 3, the first limiting ring 1002 and the second limiting ring 1003 are respectively located on both sides of the limiting plate 1004, the first limiting ring 1002 and the second limiting ring 1003 are respectively used for limiting the limiting plate 1004, and the fixing rod 1001 slides along the limiting plate 1004; an adjusting component is arranged in the circular through hole of the second drill rod 3, and the adjusting component is used to control the movement of the drill bit 4 according to the hardness of the drilling site.

[0061] In the above solution, a displacement sensor (the displacement sensor is an existing device, and its specific structure is not drawn in detail in the figure) is arranged on the fixing rod 1001 to detect the distance that the fixing rod 1001 moves upward relative to the limiting plate 1004. Both the first limiting ring 1002 and the second limiting ring 1003 are composed of a circular ring and uniformly distributed limiting teeth, the limiting plate 1004 is composed of a supporting plate and two groups of limiting teeth, each group of limiting teeth on the limiting plate 1004 is uniformly distributed in a circular shape, and the two groups of limiting teeth on the limiting plate 1004 are respectively located on the upper and lower sides of the supporting plate of the limiting plate 1004.

[0062] As Figures 4 - 9 shown in the figure, the adjusting component includes: a second fixing plate 1101 fixedly connected to the circular through hole of the second drill rod 3; a sliding rod 1102 slidably connected to the second fixing plate 1101, the sliding rod 1102 is rotatably connected with a disc 1103, the disc 1103 is detachably connected to the first limiting ring 1002, and a first elastic member 1104 is fixedly connected between the sliding rod 1102 and the second fixing plate 1101.

[0063] In the above solution, the diameter of the disc 1103 is greater than or equal to the diameter of the first limiting ring 1002, which is used to apply a more uniform force to the first limiting ring 1002 to avoid stress concentration. The first elastic member 1104 is a spring and is initially in a state of storing energy.

[0064] As Figure 5 、 Figure 7 and Figure 9 shown in the figure, the moving component includes: a limiting rod 1201 fixedly connected to the T-shaped plate 6; a limiting bent plate 1202 fixedly connected to the circular through hole of the second drill rod 3, and the limiting bent plate 1202 is used to limit the limiting rod 1201; a second elastic member 1203 is fixedly connected between the T-shaped plate 6 and the first fixing plate 905, and the distance from the outermost periphery of the spiral blade on the first drill rod 2 to the central axis of the second drill rod 3 is equal to the maximum distance from the rotating disc 7 to the central axis of the second drill rod 3.

[0065] In the above solution, the number of the limiting rods 1201 is two. A spherical surface is provided at the top of the limiting rod 1201 to reduce the frictional force generated when sliding along the limiting bent plate 1202. The number of the limiting bent plates 1202 is two. The limiting bent plate 1202 is used to gradually change the limiting position of the limiting rod 1201 when the first fixing plate 905 rotates. The second elastic member 1203 is a tension spring and is initially in a stretched and energy-stored state. The distance from the outermost periphery of the spiral blade on the first drill rod 2 to the central axis of the second drill rod 3 is equal to the maximum distance from the rotating disk 7 to the central axis of the second drill rod 3, so as to make the size of the hole drilled by the rotating disk 7 consistent with the size of the hole drilled by the spiral blade on the first drill rod 2, and reduce the wear of the spiral blade on the first drill rod 2 in the soil.

[0066] When using this device to drill the position of the ore body, the staff needs to first drive this device to move to the drilling position, and then start the device to carry out drilling. The staff controls the driving member 101 through the operating platform on the moving vehicle frame 1 to drive the first drill rod 2 to swing to the vertical state, and then controls the driving member 101 through the operating platform to drive the first drill rod 2 to gradually move downward and rotate. The first drill rod 2 drives the second drill rod 3 and the drill bit 4 to move downward. When the first drill rod 2 moves downward, the first drill rod 2 rotates under the control of the moving vehicle frame 1. The first drill rod 2 drives the second drill rod 3 to rotate, and the second drill rod 3 drives the limiting plate 1004 to rotate. In the initial state, the disk 1103 makes the first limiting ring 1002 maintain contact with the limiting plate 1004 under the action of the elastic force of the first elastic member 1104, so that the limiting plate 1004 limits the first limiting ring 1002 and drives the first limiting ring 1002 to rotate. The first limiting ring 1002 drives the disk 1103 and the fixing rod 1001 to rotate. The fixing rod 1001 drives the drill bit 4 to rotate to drill the soil, and the soil generated during the drilling process is brought to the outside through the spiral blade provided on the first drill rod 2.

[0067] When the drill bit 4 drills downward, it first contacts the soil layer. At this time, the resistance received by the downward movement of the drill bit 4 is not enough to overcome the elastic force of the first elastic member 1104, so that the first limiting ring 1002 always contacts the limiting plate 1004, ensuring that the drill bit 4 is always in a rotating state. As the drill bit 4 moves downward, the rotating disk 7 gradually contacts the soil and rotates under the drive of the second drill rod 3 to further expand the hole in the soil. And when the rotating disk 7 rotates, it rotates automatically under the friction of the soil to crush and refine the soil, facilitating the spiral blade on the first drill rod 2 to push out the soil, so as to expand the diameter of the hole drilled by the drill bit 4 to be the same as the diameter of the circle corresponding to the spiral blade on the first drill rod 2, thereby reducing the degree of wear caused by the friction between the spiral blade and the soil when rotating in the soil layer, and reducing the possibility of damaging the soil structure when the spiral blade scrapes the soil.

[0068] When the drill bit 4 moves downward to contact the hard layer, the drill bit 4 moves upward relative to the second drill pipe 3 under the extrusion of the hard layer. The drill bit 4 drives the first friction block 1002 to move upward through the fixing rod 1001. The first friction block 1002 drives the disc 1103 to move upward. The disc 1103 moves upward to compress the first elastic member 1104, so that the first friction block 1002 no longer contacts the friction plate 1004. At this time, the drill bit 4 loses power and stops rotating. And because the hard layer is hard, the drill bit 4 continues to move upward until it drives the second limiting ring 1003 to move upward through the fixing rod 1001 and contact the limiting plate 1004. At this time, the displacement sensor transmits a signal to the workbench of the mobile carriage 1. The staff can judge the formation where the drill bit 4 is located through the signal and reduce the downward movement speed of the drill bit 4. After the second limiting ring 1003 contacts the limiting plate 1004, the limiting plate 1004 drives the drill bit 4 to rotate through the second limiting ring 1003 and the fixing rod 1001. And during the downward movement process, the resistance encountered by the drill bit 4 during drilling increases, so that the drill bit 4 continuously applies force to the second limiting ring 1003 to ensure that the second limiting ring 1003 always contacts the limiting plate 1004.

[0069] When the fixing rod 1001 moves upward, the fixing rod 1001 drives the adjacent rack 902 to move upward through the sleeve 901. The rack 902 drives the adjacent rectangular block 903 to move upward. The rectangular block 903 moves upward to release the limitation on the adjacent limiting block 907. The rack 902 moves upward and meshes with the adjacent gear 906 to drive the adjacent gear 906 to rotate. The gear 906 drives the adjacent T-shaped plate 6 to rotate through the adjacent two telescopic rods 904. The T-shaped plate 6 drives the adjacent rotating disc 7 and the adjacent two limiting rods 1201 to rotate. While the T-shaped plate 6 rotates, under the action of the elastic force of the adjacent second elastic member 1203 and the limitation of the limiting bent plate 1202 on the adjacent limiting rod 1201, it slides toward the direction of the fixing rod 1001. The T-shaped plate 6 drives the rotating disc 7 to move, realizing shortening the extending length of the rotating disc 7 and reducing the inclination angle of the rotating disc 7, so as to reduce the contact area between the rotating disc 7 and the hard layer, ensure that the rotating disc 7 can rotate normally under the drive of the second drill pipe 3, and crush the hard layer to expand the hole formed by the downward movement of the drill bit 4, reducing the wear of the spiral blades on the first drill pipe 2 during drilling in the hard layer.

[0070] When the drill bit 4 moves downward to the required depth of the drilled hole and no ore body is detected, the current drilling work is completed. Subsequently, the staff controls the first drill pipe 2 to move upward through the operating platform on the mobile carriage 1, so that the first drill pipe 2 drives the second drill pipe 3 and its attached parts to move upward and out of the hole.

[0071] If the existence of an ore body is detected during the downward movement of the drill bit 4, the staff is informed to stop drilling downward through the sensor on the drill bit 4, and the first drill pipe 2 drives the second drill pipe 3 and its attached parts to move upward and out of the hole.

[0072] When the second drill pipe 3 moves upward, the sliding rod 1102 slides downward relative to the second drill pipe 3 under the elastic force of the first elastic member 1104. The sliding rod 1102 drives the disc 1103 to slide downward, and the disc 1103 drives the first limiting ring 1002 to slide downward. The first limiting ring 1002 drives the drill bit 4 to slide downward through the fixing rod 1001 until the first limiting ring 1002 contacts the limiting plate 1004, completing the reset of the drill bit 4.

[0073] When the fixing rod 1001 slides downward, the fixing rod 1001 drives the adjacent rack frame 902 to slide downward through the adjacent sleeve 901. The downward sliding of the rack frame 902 drives the adjacent gear 906 to rotate. The rotation of the gear 906 drives the T-shaped plate 6 to rotate through the adjacent two telescopic rods 904. And the limiting rod 1201 slides toward the periphery of the second drill pipe 3 under the limitation of the adjacent limiting bent plate 1202. The two limiting rods 1201 jointly drive the adjacent T-shaped plate 6 to slide toward the periphery of the second drill pipe 3, and at the same time, the adjacent second elastic member 1203 returns to the initial energy storage state. The fixing rod 1001 continues to slide downward and drives the two rack frames 902 to slide downward through the sleeve 901, so that the rack frame 902 no longer meshes with the adjacent gear 906. The rack frame 902 drives the adjacent rectangular block 903 to slide downward between the adjacent two limiting blocks 907 to limit the adjacent two limiting blocks 907, completing the reset of the device.

[0074] Embodiment 2: On the basis of Embodiment 1, as Figure 4 、 Figure 5 、 Figure 10 and Figure 11 shown, it further includes: a locking assembly, arranged on the side wall of the circular through hole of the second drill pipe 3, and the locking assembly is used to lock the state of the drill bit 4. The locking assembly includes: a frustum block 1301, fixedly connected to the sliding rod 1102; a fixed shell 1302, fixedly connected to the side wall of the circular through hole of the second drill pipe 3. The symmetry axis of the fixed shell 1302 passes through the central axis of the second drill pipe 3 and is perpendicular to the central axis of the second drill pipe 3. A sliding plate 1303 is slidably connected to the fixed shell 1302, and the sliding plate 1303 is used to limit the frustum block 1301. A third elastic member 1304 is fixedly connected between the fixed shell 1302 and the sliding plate 1303; an unlocking assembly, arranged on the sliding plate 1303, and the unlocking assembly is used to release the locking of the sliding plate 1303 on the frustum block 1301.

[0075] In the above solution, the diameter of the circle corresponding to the upper side of the frustum block 1301 is smaller than the shortest distance between the two sliding plates 1303, which is used to ensure that the sliding plates 1303 can contact the side surface of the frustum block 1301. The diameter of the circle corresponding to the lower side of the frustum block 1301 is larger than the shortest distance between the two sliding plates 1303, which is used to ensure that the two sliding plates 1303 can limit the frustum block 1301. The symmetry axis of the fixed housing 1302 passes through the central axis of the second drill rod 3 and is perpendicular to the central axis of the second drill rod 3, which is used to apply a stable extrusion force to the sliding plates 1303 without stress concentration. The third elastic member 1304 is a spring.

[0076] As Figure 8 、 Figure 10 and Figure 11 shown, the unlocking assembly includes: a winding frame 1401, rotatably connected to the T-shaped plate 6. A rope 1402 is fixedly connected between the winding frame 1401 and the sliding plate 1303. The rope 1402 passes through the second drill rod 3 and the fixed housing 1302.

[0077] In the above solution, a rectangular plate is provided on the winding frame 1401, which is convenient for the staff to twist it. The rope 1402 is made of a smooth surface material, such as polyethylene material, which is convenient for the movement of the rope 1402 when it is wound by the winding frame 1401.

[0078] When the drill bit 4 moves down to contact the hard layer, the drill bit 4 moves upward relative to the second drill rod 3 under the extrusion of the hard layer. The drill bit 4 drives the fixing rod 1001 to move upward. The fixing rod 1001 drives the first limiting ring 1002 to move upward. The first limiting ring 1002 drives the disc 1103 to move upward. The disc 1103 drives the frustum block 1301 to move upward through the sliding rod 1102. The frustum block 1301 moves upward and squeezes the two sliding plates 1303. The two sliding plates 1303 move away from each other and compress the adjacent third elastic members 1304 respectively. When the lower side surface of the frustum block 1301 passes through the upper side surfaces of the two sliding plates 1303, the two sliding plates 1303 move toward each other and reset under the action of the adjacent third elastic members 1304 respectively and lock the frustum block 1301, avoiding the situation that when the drill bit 4 moves downward and encounters a beast cave, the drill bit 4 loses the reaction force of the hard layer on it, and the drill bit 4 suddenly stops rotating under the action of the elastic force of the first elastic member 1104 and moves downward relative to the second drill rod 3, and avoiding the occurrence of the situation that after passing through the beast cave, the drill bit 4 has to squeeze the hard layer again to repeat the above actions, causing additional extrusion wear to the drill bit 4.

[0079] When the current drilling is completed and the first drill pipe 2, the second drill pipe 3 and the accessory parts on the second drill pipe 3 are removed from the hole, the worker rotates the winding frame 1401 to make the adjacent ropes 1402 pull the adjacent sliding plates 1303. The two sliding plates 1303 move away from each other to release the limit on the frustum block 1301 and respectively squeeze the adjacent third elastic members 1304. The frustum block 1301 moves downward to reset under the action of the elastic force of the first elastic member 1104. Subsequently, the worker releases the wound adjacent ropes 1402 by rotating the winding frame 1401. At the same time, the two sliding plates 1303 move away from each other to reset under the drive of the adjacent third elastic members 1304 and respectively drive the adjacent ropes 1402 to move back to their original positions.
