Description

Technical Field

[0001] This invention belongs to the field of geological drilling technology, specifically relating to a geological drilling directional anti-deviation device and its drilling method. Background Technology

[0002] Geological drilling refers to a geological engineering project that uses certain drilling machinery and equipment and processes to obtain rock cores below the surface in order to make reliable evaluations of geological and mineral resource parameters. Geological drilling aims to find out underground geological conditions. Whether it is to understand the strata and geological structure during geological surveys or to find out the occurrence, grade and reserves of minerals during detailed surveys, drilling methods are required for exploration.

[0003] In existing technologies, during drilling, the vibration of the drill bit can cause it to deviate. As the drilling depth increases, the deviation distance also gradually increases. This deviation is most likely to occur when the drill bit first contacts the ground. Drill bit deviation can easily damage the drill bit and drill rod, increasing costs and time. Insufficiently straight boreholes can lead to uneven hole diameters, affecting drilling quality and efficiency. Deviation from the design position can prevent the borehole from meeting engineering requirements, affecting project progress and quality. Drill bit deviation can also damage underground pipelines or other facilities.

[0004] Therefore, a geological drilling directional anti-deviation device is needed to solve the problem in existing technologies where the drill bit and drill rod easily deviate during drilling, affecting the quality and efficiency of drilling. Summary of the Invention

[0005] The purpose of this invention is to provide a geological drilling directional anti-deviation device and drilling method to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a geological drilling directional anti-deviation device, comprising a base frame, and further comprising:

[0010] A circular through hole is formed in the middle of the top surface of the abutment plate. Connecting plates are fixed on both sides of the abutment plate. Movable rods are fixed on the top surfaces of the two connecting plates. Both movable rods movably pass through the support rod. A spring is sleeved on the outer surface of the movable rod. The top end of the spring is fixed to the bottom surface of the support rod, and the bottom end of the spring is fixed to the top surface of the connecting plate.

[0011] A connecting block is fixed to the outer surface of the backing plate. A movable rod is fixed to the top surface of the connecting block. An L-shaped fixing plate is fixed to one side of the top surface of the bottom frame. The end of the movable rod movably passes through the L-shaped fixing plate. A positioning component is provided on the top surface of the L-shaped fixing plate corresponding to the movable rod.

[0012] Furthermore, the positioning component includes:

[0013] A fixing block is fixed to the top surface of an L-shaped fixing plate. A rod is movably inserted through one side of the fixing block, and two insertion holes that mate with the rod are opened on the surface of the moving rod.

[0014] Two protrusions are provided and fixed to the top surface of the fixing block and the insertion rod respectively, and an elastic rope is fixed between the two protrusions.

[0015] Furthermore, the cleaning mechanism includes:

[0016] The mounting rods are provided in two parts and are fixed to the sides of the two support plates respectively. A rotating shaft is rotatably connected to one side of each of the two mounting rods. A turntable is fixed to the end of the rotating shaft. A rotating column is fixed to the surface of the turntable. A rectangular ring is movably fitted on the outer surface of the rotating column. An L-shaped push rod is fixed to the top surface of the rectangular ring. A cleaning brush that cooperates with the drill rod is fixed to the end of each of the two L-shaped push rods that are close to each other. A limit rod is fixed to the top surface of each of the two support rods. The two limit rods movably pass through the two L-shaped push rods respectively.

[0017] Furthermore, the cleaning mechanism also includes a second drive motor, which is fixedly mounted on the surface of one of the mounting rods. A transmission wheel is fixed at the end of each of the two rotating shafts away from the turntable. A belt is rotatably sleeved between the two transmission wheels. A first gear is fixedly sleeved on the outer surface of one of the rotating shafts. A second gear is fixed at the output end of the second drive motor. The first gear and the second gear mesh and transmit power.

[0018] Furthermore, a grip ring is fixed to the top of the movable rod, a pull ring is fixed to the end of the insertion rod away from the movable rod, and multiple anti-slip grooves are provided on both sides of the bottom surface of the abutment plate.

[0019] Furthermore, two fixing rods are fixed on the other side of the top surface of the bottom frame, and a collar is fixed on the side of the two fixing rods that are close to each other. A U-shaped tube is fixed between the two collars, and plugs are inserted at both ends of the U-shaped tube.

[0020] Furthermore, four rectangular casters are fixedly installed on the bottom surface of the base frame, and two side plates are fixed on both sides of the base frame, with threaded posts threaded through the top surface of the side plates.

[0021] Furthermore, a throttle is fixed to the top of the threaded post.

[0022] A drilling method for a geological drilling directional anti-deviation device includes the following steps:

[0023] (1) Adjust the drilling device by moving it to the drilling position and observing whether the liquid in the U-shaped pipe coincides with the horizontal scale line.

[0024] (2) After adjusting to the horizontal, move the insert rod to disengage it from the insertion hole, and then push the movable rod and connecting plate down under the spring force so that the abutment plate moves down to fit the ground. Then insert the insert rod into the insertion hole at the upper end to limit the movement of the rod.

[0025] (3) Start the hydraulic cylinder to push the fixed cylinder down and start the first drive motor at the same time, so that the drill rod rotates and moves down. The drill rod moves down through the limiting cylinder and then continues to move down through the circular through hole to contact the ground, thereby carrying out drilling work. The drill rod is limited by the circular through hole of the limiting cylinder and the abutment plate to prevent the drill rod from deviating when it moves down for drilling.

[0026] (4) After drilling is completed, the drill rod moves upward. At this time, the second drive motor is started, which drives the second gear to rotate. Then the second gear drives the first gear to rotate, which drives one of the shafts to rotate on the mounting rod. Then the transmission wheel and belt drive the other shaft to rotate, so that the two shafts drive the turntable to rotate, which in turn drives the rotating column to rotate. The L-shaped push rod is limited by the limit rod, so that the rotating column squeezes the rectangular ring when it rotates, which drives the L-shaped push rod to move up and down repeatedly, which in turn drives the two cleaning brushes to move up and down repeatedly to clean the surface of the drill rod during the upward movement and reduce the adhesion of debris.

[0027] Compared with the prior art, the geological drilling directional anti-deviation device provided by the present invention has at least the following beneficial effects:

[0028] (1) By setting up the limiting cylinder, the abutment plate and the anti-deviation mechanism, the drill rod is limited during the downward movement, which improves the stability of the drill rod during drilling and prevents the vibration when the drill rod and drill bit just come into contact with the ground, reducing the deviation of the drill rod during drilling, thereby improving the quality and efficiency of drilling operations. By setting up the positioning component, the stability of the abutment plate when it is in contact with the ground is improved, which is conducive to improving the stability of the drill rod during drilling.

[0029] (2) By setting up the cleaning mechanism, the cleaning brush repeatedly cleans the drill rod after drilling is completed. At the same time, the rotation and upward movement of the drill rod improves the cleaning effect of the cleaning brush and reduces the residue of corrosive stains on the surface of the drill rod, thereby protecting the drill rod.

[0030] (3) By filling the U-shaped pipe with water or other liquids, and then inserting the plugs into both ends of the U-shaped pipe, the staff can judge whether the device is level by observing whether the liquid coincides with the horizontal scale line. Then, the device is adjusted to improve the accuracy of subsequent drilling. By rotating the threaded stake, the threaded stake is inserted into the ground, which stabilizes the device and helps to improve the stability of drilling. Attached Figure Description

[0041] Example 1

[0042] Please see Figure 1-6 The present invention provides a geological drilling directional anti-deviation device, including a base frame 1, and further comprising:

[0043] Support plate 2, two support plates 2 are provided and symmetrically distributed and fixed to the top surface of the bottom frame 1. The ends of the two support plates 2 are fixed with mounting cylinders 3. Hydraulic cylinders 4 are fixedly installed inside the mounting cylinders 3. The telescopic end of the hydraulic cylinders 4 is fixed with a fixing cylinder 5. The first drive motor 6 is fixedly installed inside the fixing cylinder 5. The output end of the first drive motor 6 is fixedly installed with a drill rod 7.

[0044] Support rod 8, there are two support rods 8 and they are respectively fixed to the surface of two support plates 2. The ends of the two support rods 8 that are close to each other are fixed with limiting cylinders 9 that cooperate with drill rods 7. The lower end of the limiting cylinder 9 is provided with a stop plate 10. The top surface of the stop plate 10 is provided with an anti-deviation mechanism 11. The surfaces of the two support plates 2 are provided with cleaning mechanisms 12 corresponding to the drill rods 7.

[0045] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, it is worth noting that the anti-deviation mechanism 11 includes:

[0046] A circular through hole 111 is formed in the middle of the top surface of the abutment plate 10. A connecting plate 112 is fixed on both sides of the abutment plate 10. A movable rod 113 is fixed on the top surface of the two connecting plates 112. The two movable rods 113 movably pass through the support rod 8. A spring 115 is sleeved on the outer surface of the movable rod 113. The top end of the spring 115 is fixed to the bottom surface of the support rod 8, and the bottom end of the spring 115 is fixed to the top surface of the connecting plate 112.

[0047] A connecting block 116 is fixed to the outer surface of the abutment plate 10. A moving rod 117 is fixed to the top surface of the connecting block 116. An L-shaped fixing plate 118 is fixed to one side of the top surface of the bottom frame 1. The end of the moving rod 117 moves through the L-shaped fixing plate 118. A positioning component 119 is provided on the top surface of the L-shaped fixing plate 118 corresponding to the moving rod 117.

[0048] The circular through hole 111 on the abutment plate 10 is located directly below the limiting cylinder 9. Before drilling, the spring force of the spring 115 pushes the abutment plate 10 to contact and adhere to the ground. Through the cooperation between the limiting cylinder 9 and the circular through hole 111 of the abutment plate 10, the drill rod 7 always remains vertically downward when the drill bit of the drill rod 7 contacts the ground, thus avoiding the situation of the drill rod 7 deviating when drilling downward.

[0049] like Figure 2 As shown, the positioning component 119 includes:

[0050] The fixing block 1191 is fixed to the top surface of the L-shaped fixing plate 118. A plug rod 1192 is movably passed through one side of the fixing block 1191. Two plug holes 1193 that cooperate with the plug rod 1192 are opened on the surface of the moving rod 117.

[0051] Two protrusions 1194 are provided and are respectively fixed to the top surface of the fixing block 1191 and the insertion rod 1192. An elastic rope 1195 is fixed between the two protrusions 1194.

[0052] When the abutment 10 is in contact with the ground, the insert rod 1192 is inserted into the upper insertion hole 1193 to limit the movement rod 117, thereby maintaining the stability of the abutment 10 after it is in contact with the ground and providing support for the abutment 10. After drilling is completed, the abutment 10 is lifted off the ground by pulling up the movement rod 117. At this time, the insert rod 1192 is inserted into the lower insertion hole 1193 to limit the movement rod 117 after it is pulled up, thereby maintaining the stability of the abutment 10. After the insert rod 1192 is inserted into the insertion hole 1193, the elasticity of the elastic rope 1195 ensures that the insert rod 1192 is always inserted into the insertion hole 1193, thereby improving the stability of the insert rod 1192.

[0053] Example 2

[0054] Based on Example 1, according to Figure 4 As shown, the cleaning mechanism 12 includes:

[0055] Mounting rod 1201, two mounting rods 1201 are provided and fixed to the sides of two support plates 2 respectively. One side of each mounting rod 1201 is rotatably connected to a rotating shaft 1202. The end of the rotating shaft 1202 is fixed to a turntable 1203. A rotating column 1204 is fixed to the surface of the turntable 1203. A rectangular ring 1205 is movably sleeved on the outer surface of the rotating column 1204. An L-shaped push rod 1206 is fixed to the top surface of the rectangular ring 1205. A cleaning brush 1207 that cooperates with the drill rod 7 is fixed to the end of each of the two L-shaped push rods 1206 that are close to each other. A limit rod 1208 is fixed to the top surface of each of the two support rods 8. The two limit rods 1208 movably pass through the two L-shaped push rods 1206 respectively.

[0056] The second drive motor 1209 is fixedly mounted on the surface of one of the mounting rods 1201. The ends of the two rotating shafts 1202 away from the turntable 1203 are each fixed with a transmission wheel 1210. A belt 1211 is rotatably sleeved between the two transmission wheels 1210. A first gear 1212 is fixedly sleeved on the outer surface of one of the rotating shafts 1202. A second gear 1213 is fixed at the output end of the second drive motor 1209. The first gear 1212 and the second gear 1213 mesh and transmit power.

[0057] like Figure 2 and Figure 5 As shown, a grip ring 13 is fixed to the top of the moving rod 117, which facilitates the movement of the moving rod 117; a pull ring 14 is fixed to the end of the insertion rod 1192 away from the moving rod 117, which facilitates the movement of the insertion rod 1192; multiple anti-slip grooves 114 are provided on both sides of the bottom surface of the abutment plate 10, which improves the friction when the abutment plate 10 contacts the ground.

[0058] like Figure 1 and Figure 3 As shown, two fixing rods 15 are fixed on the other side of the top surface of the bottom frame 1. A collar 16 is fixed on the side of the two fixing rods 15 that are close to each other. A U-shaped tube 17 is fixed between the two collars 16. Both ends of the U-shaped tube 17 are plugged with plugs 18.

[0059] The two ends of the U-shaped tube 17 are equipped with horizontal scale lines. By filling the U-shaped tube 17 with water or other liquids and then inserting the plugs 18 into both ends of the U-shaped tube 17, the staff can determine whether the device is level by observing whether the liquid coincides with the horizontal scale lines. Then, the entire device can be adjusted to improve the accuracy of subsequent drilling.

[0060] like Figure 1 and Figure 3 As shown, four rectangular casters 19 are fixedly installed on the bottom surface of the base frame 1, which facilitates the movement of the entire device. Two side plates 20 are fixed on both sides of the base frame 1. Threaded stakes 21 are threaded through the top surface of the side plates 20. After the entire device is moved to the drilling position, the threaded stakes 21 are rotated to insert into the ground, thereby stabilizing the entire device and improving the stability of the drilling. A handle 22 is fixed to the top of the threaded stakes 21, which facilitates the rotation of the threaded stakes 21.

[0061] In practical use, the drilling device is moved to the drilling position, and the liquid in the U-shaped pipe 17 is observed to coincide with the horizontal scale line to adjust the drilling device. After adjusting to a horizontal position, the moving rod 1192 is disengaged from the insertion hole 1193. Then, under the elastic force of the spring 115, the movable rod 113 and the connecting plate 112 are pushed down, causing the abutment plate 10 to move down and fit against the ground. Then, the moving rod 1192 is inserted into the insertion hole 1193 at the upper end, thereby limiting the moving rod 117 and keeping the abutment plate 10 in contact with the ground. After the surface is bonded, the stability of the insertion rod 1192 is improved by the elasticity of the elastic rope 1195 after the insertion rod 1192 is inserted into the insertion hole 1193. Then, the hydraulic cylinder 4 is activated to push the fixed cylinder 5 down and at the same time, the first drive motor 6 is activated, so that the drill rod 7 rotates and moves down. The drill rod 7 moves down through the limiting cylinder 9 and then continues to move down through the circular through hole 111 to contact the ground, thereby performing drilling work. The limiting cylinder 9 and the circular through hole 111 of the abutment plate 10 limit the drill rod 7 to prevent the drill rod 7 from deviating when it moves down for drilling.

[0062] After drilling is completed, the drill rod 7 moves upward. At this time, the second drive motor 1209 is started, which drives the second gear 1213 to rotate. Then, the second gear 1213 drives the first gear 1212 to rotate, which in turn drives one of the rotating shafts 1202 to rotate on the mounting rod 1201. Then, through the transmission wheel 1210 and the belt 1211, the other rotating shaft 1202 is driven to rotate. This causes the two rotating shafts 1202 to drive the turntable 1203 to rotate, which in turn drives the rotating column 1204 to rotate. The L-shaped push rod 1206 is limited by the limiting rod 1208, so that the rotating column 1204 squeezes the rectangular ring 1205 when it rotates, which drives the L-shaped push rod 1206 to move up and down reciprocally. This, in turn, drives the two cleaning brushes 1207 to move up and down reciprocally, cleaning the surface of the drill rod 7 during the upward movement and reducing the adhesion of corrosive impurities.

[0063] The first drive motor 6, the second drive motor 1209, and the hydraulic cylinder 4 can be purchased from the market. The first drive motor 6, the second drive motor 1209, and the hydraulic cylinder 4 are equipped with power supplies. This is a mature technology in the field and has been fully disclosed. Therefore, it will not be repeated in the specification.

[0064] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
