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] Smart 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 smart construction are equipped with sensors to realize data collection during the work process, control the devices according to the data, and improve construction quality and efficiency.

[0003] In the process of determining the location of a mine, detailed geological surveys are required to accurately locate the location and size 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 down to drill holes, the sensor detects underground abnormal areas, that is, areas where the surrounding magnetism and conductivity changes caused by the ore body, so as to realize the detection of the ore body location.

[0004] However, when the existing drilling equipment is working 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, causing the spiral blade close to the drill bit to constantly rub against the soil layer, accelerating the wear of this part of the spiral blade, and affecting the overall service life of the spiral blade. In addition, when the spiral blade moves downward to drill a hole, it will lift the soil around the hole excessively upward, which can easily lead to a decrease in the compactness of the soil around the hole, affecting the stability of the foundation for subsequent construction of the mine. Summary of the invention

[0005] In order to overcome the shortcomings of existing drilling equipment that, when drilling holes in the soil layer, the spiral blades close to the drill bit constantly rub against the soil layer and cause wear, affecting the overall service life of the spiral blades, and the spiral blades easily cause the compactness of the nearby soil to decrease, the present invention provides a drilling device for intelligent construction.

DETAILED DESCRIPTION

[0021] The present invention will be described in detail below with reference to the accompanying drawings. Figure 2 The directions shown are described as examples.

[0022] Embodiment 1: A drilling device for intelligent construction, such as Figure 1-Figure 7As shown, it includes: a mobile frame 1, which is provided with a driving member 101; a first drill rod 2, which is 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, which is slidably and rotatably connected to the second drill rod 3; a rotating block 5, which is 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 consistent with the inclination direction of the spiral blade on the first drill rod 2; a rotating component, which is arranged on the T-shaped plate 6, and the rotating component adjusts the inclination angle of the rotating disk 7 according to the hardness of the drilling location; a moving component, which is arranged on the T-shaped plate 6, and the moving component adjusts the extension length of the rotating disk 7 according to the hardness of the drilling location.

[0023] In the above scheme, the driving member 101 is composed of a hydraulic rod, a swing rod, a motor and a slide rail. An operating table is provided on the mobile frame 1 for controlling the rotation of the motor output shaft on the driving member 101 and the movement of the slide rail. An annular groove is provided on the lower side of the second drill rod 3. The drill bit 4 is provided with a sensor for sensing the presence of an ore body. The specific structure is not shown in the figure. The lower part of the second drill rod 3 is provided with an angle for scraping impurities on the outer surface of the drill bit 4 when the drill bit 4 moves upward. The number of rotating blocks 5 is two (the number of parts here and in the subsequent parts is not specifically limited, only for the convenience of understanding the figure and text), which are centrally symmetrically distributed on the second drill rod 3. A plurality of protrusions are provided on the rotating disk 7 for crushing the soil during the rotation process. The inclination direction of the rotating disk 7 is consistent with the inclination direction of the spiral blade on the first drill rod 2, which is used to lift the soil upward and reduce the resistance of the rotating disk 7 when it 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.

[0024] like Figure 6-Figure 9 As shown, the rotating assembly includes: a sleeve 901, which is arranged in the circular through hole of the second drill rod 3, the sleeve 901 is fixedly connected to a rack rack 902, and the rack rack 902 is fixedly connected to a rectangular block 903; a telescopic rod 904, which is fixedly connected to the T-shaped plate 6, and the telescopic part of the telescopic rod 904 is fixedly connected to a first fixed plate 905, and the first fixed plate 905 is fixedly connected to a gear 906, and the gear 906 is used to engage with the rack rack 902; a limit block 907, which is fixedly connected to the gear 906, and the rectangular block 903 is used to limit the limit block 907; an L-shaped plate 908, which is 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 to the first fixed plate 905; a connecting assembly, which is arranged on the drill bit 4, and is used to change the movement mode of the drill bit 4 according to the hardness of the drilling location.

[0025] In the above scheme, there are two rack racks 902, which are symmetrically distributed on both sides of the sleeve 901. There are two telescopic rods 904, which are used to enhance the stability of the first fixed plate 905 during rotation. There are two limit blocks 907, and the distance between the two limit blocks 907 is equal to the width of the rectangular block 903. The two limit blocks 907 are limited in the initial position of the rectangular block 903 to ensure that the gear 906 does not rotate. When the rectangular block 903 releases the limit on the two limit blocks 907, the gear 906 engages with the rack rack 902. The cross-sectional shape of the limit block 907 is semicircular, and the two edges where the arc surface of the limit block 907 intersects with the horizontal plane are provided with inclined surfaces to facilitate the rectangular block 903 to move between the two limit blocks 907.

[0026] like Figure 4-Figure 8 , Fig.10 and Fig.11 As shown, the connecting assembly includes: a fixed rod 1001, fixedly connected to the drill bit 4, a sleeve 901 is rotatably connected to the fixed rod 1001, and the fixed 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 to limit the limiting plate 1004, and the fixed rod 1001 slides along the limiting plate 1004; an adjusting assembly, arranged in the circular through hole of the second drill rod 3, and the adjusting assembly is used to control the movement of the drill bit 4 according to the hardness of the drilling location.

[0027] In the above scheme, a displacement sensor is arranged on the fixed rod 1001 (the displacement sensor is an existing device, and its specific structure is not drawn in detail in the figure), which is used to detect the distance that the fixed rod 1001 moves upward relative to the limit plate 1004. The first limit ring 1002 and the second limit ring 1003 are both composed of circular rings and limit teeth evenly distributed in annular shapes. The limit plate 1004 is composed of a support plate and two groups of limit teeth. Each group of limit teeth on the limit plate 1004 is evenly distributed in annular shapes. The two groups of limit teeth of the limit plate 1004 are respectively located on the upper and lower sides of the support plate of the limit plate 1004.

[0028] like Figure 4-Figure 9 As shown, the adjustment assembly includes: a second fixed plate 1101, fixedly connected to the circular through hole of the second drill rod 3; a sliding rod 1102, slidably connected to the second fixed plate 1101, the sliding rod 1102 is rotatably connected to a disk 1103, the disk 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 fixed plate 1101.

[0029] In the above scheme, the diameter of the disk 1103 is greater than or equal to the diameter of the first limiting ring 1002, and 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 stored force state.

[0030] like Figure 5 , Figure 7 and Fig. 9 As shown, the movable assembly includes: a limit rod 1201, fixed to the T-shaped plate 6; a limit bend plate 1202, fixed to the circular through hole of the second drill rod 3, and the limit bend plate 1202 is used to limit the limit rod 1201; a second elastic member 1203, fixed between the T-shaped plate 6 and the first fixed plate 905, and the distance from the outermost edge 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.

[0031] In the above scheme, there are two limit rods 1201, and a spherical surface is provided on the top of the limit rod 1201 to reduce the friction generated when sliding along the limit bend plate 1202. There are two limit bend plates 1202. The limit bend plate 1202 is used to gradually change the limit position of the limit rod 1201 when the first fixed plate 905 rotates. The second elastic member 1203 is a tension spring, and is initially in a stretched and force-storing state. The distance from the outermost edge 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, which is used 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, thereby reducing the wear of the spiral blade on the first drill rod 2 in the soil.

[0032] When using the device to drill at the location of the ore body, the staff needs to first drive the device to the drilling position, and then start the device to start drilling. The staff controls the driving member 101 through the operating table on the mobile frame 1 to drive the first drill rod 2 to swing to a vertical state, and then controls the driving member 101 through the operating table 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 mobile frame 1, and the first drill rod 2 drives the second drill rod 3 The second drill rod 3 drives the limiting plate 1004 to rotate. In the initial state, the disc 1103 maintains 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, driving the first limiting ring 1002 to rotate. The first limiting ring 1002 drives the disc 1103 and the fixed rod 1001 to rotate. The fixed 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 blades arranged on the first drill rod 2.

[0033] When the drill bit 4 drills downward, it first contacts the soil layer. At this time, the resistance encountered by the drill bit 4 when moving downward is not enough to overcome the elastic force of the first elastic member 1104, so that the first limit ring 1002 is always in contact with the limit 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 driven by the second drill rod 3 to further expand the hole in the soil. When rotating, the rotating disk 7 rotates due to the friction of the soil, crushing and refining the soil, making it easier for the spiral blades on the first drill rod 2 to push out the soil, thereby expanding the diameter of the hole drilled by the drill bit 4 to the same diameter as the circle corresponding to the spiral blades on the first drill rod 2, thereby reducing the degree of wear caused by the friction between the spiral blades and the soil when rotating in the soil layer, and reducing the possibility of damaging the soil structure when the spiral blades scrape the soil.

[0034] When the drill bit 4 moves down to contact with the hard layer, the drill bit 4 is squeezed by the hard layer and moves upward relative to the second drill rod 3. The drill bit 4 drives the first friction block 1002 to move upward through the fixed 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 is no longer in contact with the friction plate 1004. At this time, the drill bit 4 loses power and stops rotating. Since the hard layer is hard, the drill bit 4 continues to move upward until it drives the second limit ring 1002 through the fixed rod 1001. 3 moves upward and contacts with the limit plate 1004. At this time, the displacement sensor transmits a signal to the workbench of the mobile frame 1. The staff can judge the stratum where the drill bit 4 is located through the signal and reduce the downward movement speed of the drill bit 4. After the second limit ring 1003 contacts with the limit plate 1004, the limit plate 1004 drives the drill bit 4 to rotate through the second limit ring 1003 and the fixing rod 1001, and the resistance to drilling of the drill bit 4 increases during the downward movement, so that the drill bit 4 continuously applies force to the second limit ring 1003, ensuring that the second limit ring 1003 is always in contact with the limit plate 1004.

[0035] When the fixed rod 1001 moves upward, the fixed rod 1001 drives the adjacent rack 902 to move upward through the sleeve 901, and the rack 902 drives the adjacent rectangular block 903 to move upward. The rectangular block 903 moves upward to release the limit of the adjacent limit block 907, and the rack 902 moves upward to engage 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 two adjacent telescopic rods 904, and the T-shaped plate 6 drives the adjacent rotating disk 7 and the two adjacent limit rods 1201 to rotate. At the same time as the T-shaped plate 6 rotates At the same time, under the action of the elastic force of the adjacent second elastic member 1203 and the limiting position of the adjacent limiting rod 1201 by the limiting bent plate 1202, it slides toward the direction of the fixed rod 1001, and the T-shaped plate 6 drives the rotating disk 7 to move, thereby shortening the extended length of the rotating disk 7 and reducing the inclination angle of the rotating disk 7, thereby reducing the contact area between the rotating disk 7 and the hard layer, ensuring that the rotating disk 7 can rotate normally under the drive of the second drill rod 3, and crushing the hard layer to expand the hole formed by the downward movement of the drill bit 4, thereby reducing the wear of the spiral blades on the first drill rod 2 when drilling holes in the hard layer.

[0036] When the drill bit 4 moves down to the required depth of the hole to be drilled and still no ore body is detected, the drilling work is completed. Then the staff controls the first drill rod 2 to move upward through the operating table on the mobile frame 1, so that the first drill rod 2 drives the second drill rod 3 and its attached parts to move upward and out of the hole.

[0037] If the presence of an ore body is detected during the downward movement of the drill bit 4, the sensor on the drill bit 4 will inform the staff to stop drilling downward, and the first drill rod 2 will drive the second drill rod 3 and its attached parts to move upward and out of the hole.

[0038] When the second drill rod 3 moves upward, the sliding rod 1102 slides downward relative to the second drill rod 3 under the action of the elastic force of the first elastic member 1104, the sliding rod 1102 drives the disc 1103 to slide downward, 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 fixed rod 1001, until the first limiting ring 1002 contacts the limiting plate 1004, and the drill bit 4 is reset.

[0039] When the fixed rod 1001 slides downward, the fixed rod 1001 drives the adjacent rack 902 to slide downward through the adjacent sleeve 901, and the rack 902 slides downward to drive the adjacent gear 906 to rotate. The rotation of the gear 906 drives the T-shaped plate 6 to rotate through the two adjacent telescopic rods 904, and the limiting rod 1201 slides toward the periphery of the second drill rod 3 under the limit 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 rod 3, and at the same time, the adjacent second elastic member 1203 is restored to the initial force storage state. The fixed rod 1001 continues to slide downward through the sleeve 901 to drive the two racks 902 to slide downward, so that the rack 902 no longer meshes with the adjacent gear 906, and the rack 902 drives the adjacent rectangular block 903 to slide downward to between the two adjacent limit blocks 907, and limits the two adjacent limit blocks 907 to complete the resetting of the device.

[0040] Embodiment 2: Based on embodiment 1, Figure 4 , Figure 5 , Fig.10 and Fig.11 As shown, it also includes: a locking component, which is arranged on the side wall of the circular through hole of the second drill rod 3, and the locking component is used to lock the state of the drill bit 4. The locking component includes: a truncated cone block 1301, which is fixed to the sliding rod 1102; a fixed shell 1302, which is fixed to the side wall of the circular through hole of the second drill rod 3, and the symmetry axis of the fixed shell 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. The fixed shell 1302 is slidably connected to a sliding plate 1303, and the sliding plate 1303 is used to limit the truncated cone block 1301. A third elastic member 1304 is fixed between the fixed shell 1302 and the sliding plate 1303; an unlocking component, which is arranged on the sliding plate 1303, and the unlocking component is used to release the locking of the sliding plate 1303 on the truncated cone block 1301.

[0041] In the above scheme, the diameter of the circle corresponding to the upper side of the truncated cone block 1301 is smaller than the shortest distance between the two sliding plates 1303, which is used to ensure that the sliding plate 1303 can contact the side of the truncated cone block 1301. The diameter of the circle corresponding to the lower side of the truncated cone 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 truncated cone block 1301. The axis of symmetry of the fixed shell 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 plate 1303 without stress concentration. The third elastic member 1304 is a spring.

[0042] like Figure 8 , Fig.10 and Fig.11As 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 , and the rope 1402 passes through the second drill rod 3 and the fixed shell 1302 .

[0043] In the above scheme, a rectangular plate is provided on the winding frame 1401 to facilitate the staff to twist it, and the rope 1402 is made of a material with a smooth surface, such as polyethylene, to facilitate the movement of the rope 1402 when being wound by the winding frame 1401.

[0044] When the drill bit 4 moves down to contact with the hard layer, the drill bit 4 is squeezed by the hard layer and moves upward relative to the second drill rod 3, the drill bit 4 drives the fixed rod 1001 to move upward, the fixed rod 1001 drives the first limit ring 1002 to move upward, the first limit ring 1002 drives the disc 1103 to move upward, the disc 1103 drives the truncated cone block 1301 to move upward through the sliding rod 1102, the truncated cone block 1301 moves upward to squeeze the two sliding plates 1303, the two sliding plates 1303 move back to back to compress the adjacent third elastic member 1304 respectively, when the truncated cone block 1301 When the lower side surface 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 and lock the truncated cone block 1301, so as to prevent the drill bit 4 from encountering a beast's hole when moving downward, causing the drill bit 4 to lose the reaction force of the hard layer on it, and the drill bit 4 suddenly stops rotating due to the downward movement relative to the second drill rod 3 under the action of the elastic force of the first elastic member 1104, and to prevent the drill bit 4 from squeezing the hard layer again to repeat the above action after passing the beast's hole, causing additional extrusion and wear to the drill bit 4.

[0045] When the drilling is completed and the first drill rod 2, the second drill rod 3 and the attached parts on the second drill rod 3 are removed from the hole, the staff rotates the winding rack 1401 to make the adjacent ropes 1402 pull the adjacent sliding plates 1303. The two sliding plates 1303 move backwards to release the limit on the truncated cone block 1301, and squeeze the adjacent third elastic members 1304 respectively. The truncated cone block 1301 moves downward and resets under the action of the elastic force of the first elastic member 1104. Then the staff releases the wound adjacent ropes 1402 by rotating the winding rack 1401. At the same time, the two sliding plates 1303 move backwards and reset under the drive of the adjacent third elastic members 1304, and respectively drive the adjacent ropes 1402 to move and reset.
