Description

Technical Field

[0001] The present invention relates to the field of coal mine drilling, and in particular to a drilling rig and an application method thereof. Background Art

[0002] A mine refers to a place rich in coal resources, which is generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, it is generally chosen to excavate coal in tunnels underground. This is an underground coal mine. Due to the needs of installation and use, underground tracks in coal mines often require drilling, expansion and chamfering.

[0003] In the process of drilling in coal mines, the base surface is generally drilled through a drill rod, and some drill rods are threadedly connected to the joint. After long-term use, the drill rod and the joint are subjected to external forces such as vibration and impact, which will cause the threaded part on the joint to gradually loosen. Moreover, as time goes by, the thread on the joint is easily worn flat, resulting in a gap between the drill rod and the joint. The drill rod will become loose due to the gap, causing the drill rod to deviate during the drilling process. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a drilling rig and an application method.

[0005] In a first aspect, the present invention provides a drilling rig, including a lifting type drilling rig, wherein the lifting type drilling rig includes a drilling rig body and a chuck slidably connected to one side of the drilling rig body via a driving member, and further includes:

[0006] A threaded sleeve is fixed to the bottom center of the base through a power assembly;

[0007] a drill rod, threadedly connected to the interior of the threaded sleeve;

[0008] a disc rotatably connected to the outer wall of the power assembly;

[0009] a conversion assembly disposed on the top of the disc; when the drill rod is operating normally, the conversion assembly connects the disc and the power assembly; when the threaded connection between the drill rod and the threaded sleeve is tilted and loosened, the conversion assembly switches the connection between the disc and the holder, thereby switching the connection between the disc and the power assembly and the holder according to different states;

[0010] A gap filling mechanism is fixedly mounted on the bottom of the disc to straighten the drill rod and provide stable support when the connection between the drill rod and the threaded sleeve becomes loose, and to fill the gap between the drill rod and the threaded sleeve with metal glue to secure them after straightening;

[0011] Among them, the gap filling mechanism monitors whether the drilling trajectory of the drill rod is deviated, and is conducive to preventing the drill rod from causing wear to the gap filling mechanism during rotation. When the connection between the drill rod and the threaded sleeve is loose, causing deviation between the two, the gap filling mechanism will detect pressure information, and then the conversion mechanism will cancel the connection between the power assembly and the disc. After the connection is canceled, the disc continues to rotate under the action of inertia, and then, under the action of the conversion mechanism, it keeps synchronization with the holder and stops following the rotation of the power assembly, thereby stopping the rotation of the gap filling mechanism. Then, the gap filling mechanism will first straighten the drill rod so that the axis of the drill rod coincides with the axis of the drive shaft of the power assembly. After the drill rod is straightened, the gap filling mechanism will provide support force to the straightened drill rod to maintain the straightened state. During the continued rotation of the drill rod and the threaded sleeve, the gap filling mechanism will spray metal glue into the gap caused by wear at the connection between the drill rod and the threaded sleeve. After the metal glue sprayed into the gap cools, the threaded sleeve and the drill rod connection form a fixed connection, which is conducive to maintaining a stable connection between the two.

[0012] Preferably, the gap filling mechanism includes:

[0013] A controller is fixedly mounted on the side wall of the card seat;

[0014] There are four cylinders, which are fixed to the bottom of the disc in a circular array through a mounting plate; the telescopic ends of two adjacent cylinders are fixedly connected to an arc-shaped storage box through a detection member; the telescopic ends of the other two cylinders are fixedly connected to an arc-shaped straightening member through a detection member;

[0015] There are two groups of automatic spray heads, which are fixedly connected to the top of the arc-shaped storage box at the corresponding position in a curved array;

[0016] The arc-shaped storage box and the arc-shaped straightening member are combined and connected to support the drill pipe together;

[0017] Among them, after the detection part recognizes that the position of the drill rod is offset, the drill rod can be pushed to a position coaxial with the threaded sleeve through the cooperation between the arc storage box and the arc straightening part, and the arc storage box and the arc straightening part will limit the drill rod after being pushed to the predetermined position, which is beneficial for the drill rod to be supported and limited after straightening, and is beneficial for avoiding the situation where the drill rod is offset again after being straightened. After the drill rod is straightened, the controller will control the automatic spray head to spray the metal glue in the arc storage box into the gap between the threaded sleeve and the drill rod. It can be selected that the automatic spray head includes a micro pump and a nozzle, and the metal glue is sprayed along the nozzle through the micro pump, which is beneficial for fixing the drill rod after straightening, maintaining the drill rod and the threaded sleeve in a straight line, and facilitating the subsequent drill rod to continue drilling.

[0018] Preferably, the sliding sleeve is fixed to the telescopic end of the cylinder;

[0019] A trigger rod, one end of which is fixedly connected to the arc-shaped material storage box or the arc-shaped straightening member via a gasket, and the other end of which is slidably inserted into the interior of the sliding sleeve via an elastic telescopic rod; the sliding sleeve pushes the trigger rod to move after pushing the elastic telescopic rod to be fully compressed;

[0020] A pressure sensor is installed inside the sliding sleeve via an elastic rod; when the drill pipe deviates, the sliding sleeve is pushed to apply pressure to the pressure sensor;

[0021] Among them, the cylinder performs telescopic movement to drive the sliding sleeve toward the drill rod, and the sliding sleeve will first compress the elastic telescopic rod to shrink. After the elastic telescopic rod shrinks to the maximum shrinkage distance, the sliding sleeve pushes the trigger rod toward the drill rod through the elastic telescopic rod, and the trigger rod will push the corresponding arc storage box or arc straightening piece toward the drill rod, thereby straightening the drill rod through the cooperation between the arc storage box or the arc straightening piece, and continue to provide support force to maintain the straightening state of the drill rod after the position of the drill rod is straightened, which is conducive to the subsequent automatic spray head to spray metal glue in the gap for fixation.

[0022] Preferably, a first arc-shaped push plate is fixedly connected to the top of one of the arc-shaped straightening members, the first arc-shaped push plate is arranged obliquely, and an elastic member is fixed between the bottom of the first arc-shaped push plate and the arc-shaped straightening member.

[0023] Preferably, the top of another of the arc-shaped straightening members is fixedly connected to a second arc-shaped push plate, and the top of the second arc-shaped push plate is fixed with multiple supports in a curved array, and rollers are rotatably connected between the side walls of all the supports, and the ends of the rollers are fixedly connected to fans.

[0024] Preferably, a storage cavity is provided on the top of all the supports, and all the rollers are located directly above the storage cavities at corresponding positions.

[0031] generating first control information and second control information;

[0032] Sending first control information to the conversion component to control the conversion component to start switching to connect the card holder and the disc;

[0033] Sending the second control information to the cylinders to control all cylinders to start pushing out;

[0034] Among them, when the trigger rod moves in the direction of the pressure sensor and contacts the pressure sensor, it will apply an extrusion force to the pressure sensor, thereby generating a first request information after the pressure sensor senses the pressure signal, and then the pressure sensor sends the first request information to the controller, and then the controller generates a first control information and a second control information. The controller first sends the first control information to the electric push rod to control the electric push rod to start pushing out, and the electric push rod pushes the connecting block to drive one end of the insertion rod away from the power component, and makes the other end of the insertion rod cooperate with the block through magnetic attraction. The controller sends the second control information to all cylinders to control all cylinders to push out, thereby pushing the arc storage box and the arc straightening piece through the detection part to straighten and limit the drill rod.

[0035] Preferably, it also includes:

[0037] Sending the third control information to the automatic spray head to control the automatic spray head to spray the material into the gap;

[0038] Among them, while generating the first control information and the second control information, the third control information will also be generated. The controller then sends the third control information to the automatic spray head to control the automatic spray head to start spraying, and then the automatic spray head will spray the liquid inside the arc-shaped storage box into the gap between the drill rod and the threaded sleeve to fill it.

[0039] Preferably, the specific method for obtaining the pressure sensor includes the following steps:

[0040] Obtain pressure information;

[0041] generating first request information;

[0042] Sending the first request information to the controller;

[0043] After the trigger rod applies a squeezing force to the pressure sensor, the pressure sensor obtains a pressure signal, and then the pressure sensor generates first request information and sends the first request information to the controller.

After the drill rod is straightened, the gap filling mechanism will provide support force to the straightened drill rod to maintain the straightened state.

[0063] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may conceive of other obvious variations.

[0064] like Figures 2 to 12The drilling machine shown is a lifting type drilling machine, which includes a drilling machine body 1 and a clamping seat 2 slidably connected to one side of the drilling machine body 1 through a driving member, and further includes:

[0065] The threaded sleeve 3 is fixed to the bottom center of the base 2 through the power assembly 4;

[0066] The drill rod 5 is threadedly connected to the inside of the threaded sleeve 3;

[0067] The disc 6 is rotatably connected to the outer wall of the power assembly 4;

[0068] The conversion assembly is arranged on the top of the disc 6; when the drill rod 5 is working normally, the conversion assembly connects the disc 6 and the power assembly 4. When the threaded connection between the drill rod 5 and the threaded sleeve 3 is tilted and loosened, the conversion assembly switches the connection between the disc 6 and the holder 2, so as to switch the connection between the disc 6 and the power assembly 4 and the holder 2 according to different states;

[0069] The gap filling mechanism is fixedly installed on the bottom of the disc 6 to straighten the drill rod 5 and provide stable support when the connection between the drill rod 5 and the threaded sleeve 3 is loose. After straightening, the gap between the drill rod 5 and the threaded sleeve 3 is filled with metal glue to fix it. During operation, in the process of drilling holes in coal mines, the base surface is generally drilled through the drill rod 5, and part of the drill rod 5 is threadedly connected to the joint. After long-term use, the drill rod 5 and the joint are subjected to external forces such as vibration and impact, which will cause the threaded part on the joint to gradually loosen. As time goes by, the threads on the joint are easily worn flat, resulting in a gap between the drill rod 5 and the joint. The drill rod 5 will become loose due to the gap, causing the drill rod 5 to be difficult to drill. During the process, there is a situation of deviation. The embodiment of the present invention can solve the above problem. The specific method is as follows: during the process of the drill rod 5 vertically drilling a hole into the ground, the drilling machine body 1 will drive the chuck 2 to move up and down through the driving member. Optionally, the driving member includes a motor and a screw. When the motor is started, the screw is driven to rotate through the output shaft, and the screw drives the chuck 2 threadedly connected thereto to move vertically. The power component 4 drives the threaded sleeve 3 to rotate through the motor provided inside as a power source, and the threaded sleeve 3 drives the drill rod 5 to rotate. During the rotation of the drill rod 5, during the normal rotation working process of the drill rod 5, the conversion component connects the disc 6 and the power component 4 to make them rotate synchronously, so while the power component 4 rotates, it will also The conversion assembly drives the disc 6 to rotate, and the disc 6 drives the gap filling mechanism to rotate synchronously with the drill rod 5, so that the gap filling mechanism and the drill rod 5 remain relatively stationary, which is beneficial for the gap filling mechanism to monitor whether the drilling trajectory of the drill rod 5 is deviated, and is beneficial for avoiding that the drill rod 5 causes wear to the gap filling mechanism during the rotation process. When the connection between the drill rod 5 and the threaded sleeve 3 is loose, causing an offset between the two, the gap filling mechanism will detect pressure information, and then the conversion mechanism will cancel the connection between the power assembly 4 and the disc 6. After the connection is canceled, the disc 6 continues to rotate under the action of inertia, and then, under the action of the conversion mechanism, it keeps synchronization with the card holder 2 and stops rotating with the power assembly 4. 5 and the threaded sleeve 3 are in a state of being rotated, and the gap filling mechanism will stop rotating. Then the gap filling mechanism will straighten the drill rod 5 first so that the axis of the drill rod 5 coincides with the axis of the drive shaft of the power assembly 4. After the straightening of the drill rod 5 is completed, the gap filling mechanism will provide support force to the straightened drill rod 5 to maintain the straightened state. While the drill rod 5 and the threaded sleeve 3 continue to rotate, the gap filling mechanism will spray metal glue into the gap caused by wear at the connection between the drill rod 5 and the threaded sleeve 3. After the metal glue sprayed into the gap is cooled, a fixed connection is formed at the connection between the threaded sleeve 3 and the drill rod 5, which is conducive to maintaining a stable connection between the two, thereby helping to avoid the drill rod 5 from deviating again during the drilling process.

[0070] As an embodiment of the present invention, the gap filling mechanism includes:

[0071] The controller 7 is fixedly mounted on the side wall of the card holder 2;

[0072] There are four cylinders 8, which are fixed to the bottom of the disc 6 in a circular array through a mounting plate; the telescopic ends of two adjacent cylinders 8 are fixedly connected to the arc-shaped storage box 23 through a detection member; the telescopic ends of the other two cylinders 8 are fixedly connected to the arc-shaped straightening member 10 through a detection member;

[0073] The automatic spray head 9 is provided with two groups, which are fixedly connected to the top of the arc-shaped storage box 23 at the corresponding position in a curved array;

[0074] Among them, the arc storage box 23 and the arc straightening piece 10 are combined and connected to jointly support the drill rod 5; during operation, when it is detected that the connection between the drill rod 5 and the threaded sleeve 3 is loose, the controller 7 controls all the cylinders 8 to start, and the telescopic rods of the cylinders 8 push the corresponding arc storage box 23 and the arc straightening piece 10 close to each other through the detection piece. After the arc storage box 23 and the arc straightening piece 10 are close and fitted, they will form a complete circle that adapts to the outer wall of the drill rod 5. Therefore, no matter which position the drill rod 5 itself deviates to due to the gap, after the detection piece recognizes that the position of the drill rod 5 has deviated, the drill rod 5 can be pushed to the coaxial line with the threaded sleeve 3 through the cooperation between the arc storage box 23 and the arc straightening piece 10. position, and the arc-shaped storage box 23 and the arc-shaped straightening member 10 will limit the drill rod 5 after being pushed to the predetermined position, which is beneficial for supporting and limiting the drill rod 5 after straightening, and is beneficial for avoiding the situation where the drill rod 5 deviates again after being straightened. After the drill rod 5 is straightened, the controller 7 will control the automatic spray head 9 to spray the metal glue in the arc-shaped storage box 23 into the gap between the threaded sleeve 3 and the drill rod 5. It can be selected that the automatic spray head 9 includes a micro pump and a nozzle, and the metal glue is sprayed along the nozzle through the micro pump, which is beneficial for fixing the drill rod 5 after the correction, and is beneficial for maintaining the drill rod 5 and the threaded sleeve 3 in a straight line, which is beneficial for the subsequent drill rod 5 to continue drilling.

[0075] As an embodiment of the present invention, the detection element includes:

[0076] Sliding sleeve 11, fixed to the telescopic end of cylinder 8;

[0077] The trigger rod 12 has one end fixedly connected to the arc-shaped storage box 23 or the arc-shaped straightening member 10 through a gasket, and the other end is slidably inserted into the interior of the sliding sleeve 11 through the elastic telescopic rod 13; the sliding sleeve 11 pushes the trigger rod 12 to move after pushing the elastic telescopic rod 13 to be fully compressed;

[0078] The pressure sensor 14 is installed inside the sliding sleeve 11 through an elastic rod; when the drill rod 5 deviates, the sliding sleeve 11 is pushed to apply pressure to the pressure sensor 14; during operation, when the drill rod 5 deviates, the drill rod 5 will apply a thrust in the direction of the deviation, so that the drill rod 5 will push the arc storage box 23 or the arc straightening piece 10 at the corresponding position to move away from itself, and the movement of the arc storage box 23 or the arc straightening piece 10 will push the trigger rod 12 toward the direction of the pressure sensor 14, and the trigger rod 12 will apply an extrusion force to the pressure sensor 14. After the pressure sensor 14 senses the pressure signal, the controller 7 controls all the cylinders 8 to start, and the gas The cylinder 8 performs telescopic movement to drive the sleeve 11 toward the drill rod 5. The sleeve 11 will first compress the elastic telescopic rod 13 to shrink. After the elastic telescopic rod 13 shrinks to the maximum shrinkage distance, the sleeve 11 pushes the trigger rod 12 toward the drill rod 5 through the elastic telescopic rod 13. The trigger rod 12 will push the corresponding arc storage box 23 or the arc straightening piece 10 toward the drill rod 5, thereby straightening the drill rod 5 through the cooperation between the arc storage box 23 or the arc straightening piece 10, and continue to provide support force to maintain the straightening state of the drill rod 5 after the position of the drill rod 5 is straightened, which is conducive to the subsequent automatic spray head 9 to spray metal glue in the gap for fixation.

[0079] As an embodiment of the present invention, the top of one of the arc-shaped straightening members 10 is fixedly connected with a first arc-shaped push plate 22, the first arc-shaped push plate 22 is tilted, and an elastic member 19 is fixed between the bottom of the first arc-shaped push plate 22 and the arc-shaped straightening member 10; during operation, because the gap at the connection between the drill rod 5 and the threaded sleeve 3 is downward, after spraying metal glue into the gap generated by wear, the metal glue may flow downward under the action of gravity before it cools and solidifies, thereby easily causing part of the metal glue to be lost. The embodiment of the present invention can solve the above problem, specifically in the following way: the first arc-shaped push plate The top plate of 22 is made of a material with a certain flexibility. The elastic member 19 releases the elastic force to push the top plate of the first arc-shaped push plate 22 to tilt at a certain angle, so that after the automatic spray head 9 completes the spraying of the metal glue, the metal glue flowing downward from the gap will be received by the top of the first arc-shaped push plate 22, and the metal glue flowing down will be gathered. In the process of rotation of the drill rod 5 and the threaded sleeve 3, under the guidance of the inclined surface of the first arc-shaped push plate 22, the gathered metal glue will be driven from low to high toward the gap direction, which is conducive to allowing more metal glue to enter the gap and avoiding waste of metal glue.

[0080] As an embodiment of the present invention, the top of another arc-shaped straightening member 10 is fixedly connected to a second arc-shaped push plate 15, and the top of the second arc-shaped push plate 15 is fixed with a plurality of supports 16 in a curved array, and rollers 17 are rotatably connected between the side walls of all the supports 16, and the ends of the rollers 17 are fixedly connected to fans 18; during operation, a large amount of dust and impurities will be raised during the rotation of the drill rod 5, so that some dust and impurities will adhere to the bottom of the threaded sleeve 3, and then easily affect the bonding effect of the metal glue during the spraying process. The embodiment of the present invention can solve the above problem, specifically in the following way: the roller 17 contacts the bottom of the threaded sleeve 3, so during the rotation of the threaded sleeve 3 The driving roller 17 will be driven to rotate by friction, and the rotation of the roller 17 will drive the corresponding fan 18 to rotate. The blades of the fan 18 will generate airflow during the rotation process, thereby blowing away the dust and impurities adhering to the connection between the bottom of the threaded sleeve 3 and the drill rod 5, reducing the accumulation of dust and impurities at the connection between the bottom of the threaded sleeve 3 and the drill rod 5, which is conducive to the metal glue filling and fixing the gap between the bottom of the threaded sleeve 3 and the drill rod 5, and under the flow of airflow, it is conducive to accelerating the solidification rate of the metal glue, which is conducive to avoiding the welding from flowing out of the gap between the bottom of the threaded sleeve 3 and the drill rod 5, thereby helping to improve the fixing rate of the threaded sleeve 3 and the drill rod 5 and reduce the loss of metal glue.

[0081] As an embodiment of the present invention, a storage cavity is provided on the top of all supports 16, and all rollers 17 are respectively located directly above the storage cavities at corresponding positions. Both sides of all supports 16 are symmetrically fixedly connected with inclined storage plates 20, and both ends of the two storage plates 20 are fixedly connected with connecting plates 21, and a cleaning wire 28 is fixed between the two connecting plates 21 and is in contact with the outer wall of the roller 17; when working, the roller 17 contacts with the bottom of the threaded sleeve 3 during rotation, and it is easy to adhere to some metal glue. If the metal glue accumulates on the roller 17, Too much pressure will affect the rotation of the drum. The embodiments of the present invention can solve the above problem. The specific method is as follows: during the rotation of the drum, because the cleaning wire 28 is in contact with the outer wall of the drum 17, the cleaning wire 28 will synchronously scrape off the metal glue adhering to the outer wall of the drum 17 during the rotation of the drum 17, which is beneficial to keeping the outer wall of the drum 17 clean and tidy, and is beneficial for the drum 17 to continue to drive the fan 18 to rotate. The metal glue scraped off by the cleaning wire 28 will then be collected in the storage cavity, which is beneficial to reduce the waste of metal glue.

[0082] As an embodiment of the present invention, the conversion component includes:

[0083] The electric push rod 27 is fixed to the top of the disc 6;

[0084] The stopper 25 is fixedly connected to the side wall of the card holder 2 facing the electric push rod 27;

[0085] The plug rod 24 is fixedly connected to the telescopic rod end of the electric push rod 27 through the connecting block 26, one end of which is plugged into the through hole on the outer wall of the power assembly 4, and the other end is magnetically adapted to the stopper 25 after switching; when working, the controller 7 controls the electric push rod 27 to start, and the electric push rod 27 pushes the plug rod 24 to slide out of the through hole on the outer wall of the power assembly 4 through the connecting block 26. Because both ends of the plug rod 24 have a certain degree of elasticity, during the movement of the plug rod 24, if it encounters the power assembly 4 or the stopper 25, it will elastically give way. After the connecting block 26 drives the plug rod 24 to separate from the power assembly 4, it will continue to rotate under the action of inertia of the disc 6. When the other end of the plug rod 24 contacts the stopper 25, it will be magnetically attracted by the stopper 25. Therefore, during the continued rotation of the power assembly 4, the stopper 25 blocks and limits the plug rod 24, thereby stopping the rotation of the disc 6, and thus keeping the gap filling mechanism stationary, which is conducive to the subsequent processing of the gap between the drill rod 5 and the threaded sleeve 3.

[0086] like Figure 1 The application method of a drilling rig shown includes the following steps:

[0087] Obtaining first request information, where the first request information is generated after the pressure sensor 14 obtains pressure information;

[0088] generating first control information and second control information;

[0089] Sending the first control information to the conversion component to control the conversion component to start switching to connect the card holder 2 and the disk 6;

[0090] Send the second control information to the cylinder 8 to control all cylinders 8 to start pushing out;

[0091] Among them, after the trigger rod 12 moves in the direction of the pressure sensor 14 and contacts the pressure sensor 14, it will apply an extrusion force to the pressure sensor 14, thereby generating a first request information after the pressure sensor 14 senses the pressure signal, and then the pressure sensor 14 sends the first request information to the controller 7, and then the controller 7 generates a first control information and a second control information. The controller 7 first sends the first control information to the electric push rod 27 to control the electric push rod 27 to start pushing out, and the electric push rod 27 pushes the connecting block 26 to drive one end of the insertion rod 24 away from the power component 4, and makes the other end of the insertion rod 24 cooperate with the block 25 through magnetic attraction. The controller 7 sends the second control information to all cylinders 8 to control all cylinders 8 to push out, thereby pushing the arc storage box 23 and the arc straightening member 10 through the detection part to straighten and limit the drill rod 5.

[0092] like Figure 13As shown, as an embodiment of the present invention, it also includes:

[0093] Generating the first control information and the second control information while also generating the third control information;

[0094] The third control information is sent to the automatic spray head 9 to control the automatic spray head 9 to spray the material into the gap;

[0095] Among them, while generating the first control information and the second control information, a third control information will also be generated. Then the controller 7 sends the third control information to the automatic spray head 9 to control the automatic spray head 9 to start spraying, and then the automatic spray head 9 will spray the liquid inside the arc-shaped storage box 23 into the gap between the drill rod 5 and the threaded sleeve 3 to fill it.

[0096] like Figure 14 As shown, as an embodiment of the present invention, the specific acquisition method of the pressure sensor 14 includes the following steps:

[0097] Obtain pressure information;

[0098] generating first request information;

[0099] Sending the first request information to the controller;

[0100] After the trigger rod 12 applies a squeezing force to the pressure sensor 14 , the pressure sensor 14 obtains a pressure signal. Then, the pressure sensor 14 generates first request information and sends the first request information to the controller 7 .

[0101] Working principle of the present invention:

[0102] In the process of drilling holes in coal mines, the base surface is generally drilled through the drill rod 5, and part of the drill rod 5 is threadedly connected to the joint. After long-term use, the drill rod 5 and the joint are subjected to external forces such as vibration and impact, which will cause the threaded part on the joint to gradually loosen, and as time goes by, the thread on the joint is easily worn flat, resulting in a gap between the drill rod 5 and the joint, and the drill rod 5 will become loose due to the gap, causing the drill rod 5 to deviate during the drilling process. The embodiment of the present invention can solve the above problem. The specific method is as follows: during the process of the drill rod 5 vertically drilling a hole into the ground, the drilling machine body 1 will pass The driving member drives the card seat 2 to move up and down. Optionally, the driving member includes a motor and a screw. When the motor is started, the screw is driven to rotate through the output shaft, and the screw drives the card seat 2 threadedly connected thereto to move vertically. The power component 4 drives the threaded sleeve 3 to rotate through the motor provided inside as a power source, and the threaded sleeve 3 drives the drill rod 5 to rotate. During the rotation of the drill rod 5, during the normal rotation working process of the drill rod 5, the conversion component connects the disc 6 and the power component 4 to rotate synchronously. Therefore, when the power component 4 rotates, the disc 6 is also driven to rotate through the conversion component. The disc 6 drives the gap filling mechanism to rotate synchronously with the drill rod 5, so that the gap filling mechanism The structure and the drill rod 5 remain relatively stationary, which is beneficial for the gap filling mechanism to monitor whether the drilling trajectory of the drill rod 5 is deviated, and is beneficial for avoiding wear of the gap filling mechanism during the rotation of the drill rod 5. When the connection between the drill rod 5 and the threaded sleeve 3 is loose, causing deviation between the two, the gap filling mechanism will detect the pressure information, and then the conversion mechanism will cancel the connection between the power component 4 and the disc 6. After the connection is cancelled, the disc 6 continues to rotate under the action of inertia, and then, under the action of the conversion mechanism, it keeps synchronization with the card seat 2 and stops following the rotation of the power component 4, so that the gap filling mechanism stops rotating, and then the gap filling mechanism stops rotating. The gap filling mechanism will first straighten the drill rod 5 so that the axis of the drill rod 5 coincides with the axis of the drive shaft of the power assembly 4. After the drill rod 5 is straightened, the gap filling mechanism will provide support force to the straightened drill rod 5 to maintain the straightened state. During the process of continued rotation of the drill rod 5 and the threaded sleeve 3, the gap filling mechanism will spray metal glue into the gap caused by wear at the connection between the drill rod 5 and the threaded sleeve 3. After the metal glue sprayed into the gap cools down, a fixed connection is formed at the connection between the threaded sleeve 3 and the drill rod 5, which is conducive to maintaining a stable connection between the two, thereby helping to avoid the drill rod 5 from deviating again during the drilling process.
