Description

Technical Field

[0001] This invention relates to the field of mining drilling technology, and more specifically to a mining drilling device with adaptive adjustment. Background Technology

[0002] Mining drilling equipment is a specialized machine used in mining to drill holes of specific diameters and depths in media such as rocks and coal seams. It provides drilling for blasting operations, channels for loading explosives, and is a key piece of equipment for open-pit mining stripping and underground mining tunneling. It is also used for geological exploration drilling to obtain basic data such as the distribution of mineral strata and veins.

[0003] However, when splicing drill rods in drilling equipment, the splicing is mostly done manually. This splicing method poses safety hazards when the equipment is in use. In addition, the drill rods need to be moved repeatedly during splicing, which increases the workload of the workers. At the same time, the manual operation mode makes the splicing cycle long and cannot complete the splicing of drill rods quickly, so that the equipment cannot be put into production quickly. Summary of the Invention

[0004] The purpose of this invention is to provide a mining drilling device with adaptive adjustment to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] An adaptive adjustment mining drilling device includes a mounting base. A track drive for moving the drive unit is fixedly mounted on the bottom end of the mounting base. A mounting platform is mounted on the top of the upper surface of the mounting base. Hydraulic lifting units are symmetrically mounted on the top of the mounting platform. A hydraulic swing unit is fixedly mounted on the output end of the hydraulic lifting unit. A crossbeam is fixedly mounted on the working end of the hydraulic swing unit. A rotary head is slidably connected to the top end of the crossbeam near the hydraulic lifting unit for driving the drill rod to rotate and feed material. A hydraulic clamping unit is fixedly mounted on the top end of the crossbeam away from the rotary head for clamping the drill rod. A splicing mechanism is located on the side of the rotary head away from the hydraulic clamping unit and is fixedly connected to the upper surface of the mounting base for splicing the drill rod. A feeding mechanism is located on one side of the splicing mechanism and is fixedly connected to the upper surface of the mounting base for feeding the splicing mechanism.

[0007] Using the above technical solution, during the drilling process, the rotary head drives two drill rods that are spliced ​​together to drill. After the first drill rod is drilled into the ore body, the hydraulic clamping unit clamps the connection between the two drill rods. Then, the rotary head moves away from the hydraulic clamping unit to reset. After moving into position, it clamps the drill rod again, and the hydraulic clamping unit releases the clamp. Then, the new drill rod is placed on the splicing mechanism, which drives the new drill rod to rotate and connect it with the drill rod clamped by the rotary head. Then, the rotary head drives the drill rod to rotate and drill. The splicing mechanism can replace the manual splicing method for drill rod splicing, thereby saving time during drill rod splicing, reducing the workload of workers, improving the efficiency of the device during splicing, and further improving the smoothness of the device during operation. The hydraulic lifting unit can adjust the processing height of the device in real time, and the hydraulic swing unit can adjust the processing angle of the device accordingly.

[0008] A further improvement of the technical solution of the present invention is that: the splicing mechanism includes a mounting frame fixedly installed on the upper surface of the mounting substrate, a cylinder fixedly installed at the bottom end of the mounting frame, a sliding frame fixedly installed at the output end of the cylinder, and the sliding frame and the mounting frame are slidably engaged, two splicing rollers are symmetrically rotatably connected to the top end of the sliding frame, and the surfaces of the two splicing rollers are fixedly mounted with spirally arranged strips, a drive belt is fixedly installed at the end of the sliding frame, and the drive belt is fixedly connected to the ends of the two splicing rollers respectively, a drive motor is fixedly installed at one end of the sliding frame, and the output end of the drive motor is engaged with the drive belt.

[0009] Using the above technical solution, during the splicing process of the drill rod using the splicing mechanism, the new drill rod is placed on the splicing roller. The drive motor drives the two splicing rollers to rotate synchronously in the same direction via a drive belt, causing the drill rod placed on the splicing roller to rotate. To increase the stability of the drill rod on the splicing roller and the driving stability of the splicing roller on the drill rod, the splicing roller is provided with a strip, which can increase the friction between the splicing roller and the drill rod. Furthermore, the spirally arranged strip can drive the drill rod to rotate and provide an axial component force. Thus, the drill rod is driven by the splicing roller and the strip to gradually move towards the drill rod on the rotary device. This allows the drill rod on the splicing roller to rotate and splice with the drill rod on the rotary device, enabling the two drill rods to be connected end to end, completing the extension of the drill rod. Then, the rotary device drives the drill rod to perform drilling operations. The automated splicing mechanism replaces the manual splicing method, making drill rod splicing more time-saving and labor-saving. Furthermore, the mechanical splicing method avoids the safety issues associated with manual splicing, further improving the stability and safety of the device during use. In addition, two symmetrically arranged splicing rollers automatically center the drill rods placed on them, increasing the accuracy of splicing between two drill rods and further enhancing the reliability of the device. This makes it more convenient for operators to use. Moreover, automated splicing allows for continuous drill rod splicing without stopping the machine, accelerating the drilling process. Furthermore, the automatic centering correction of the drill rods during loading further improves the accuracy, stability, and smoothness of the splicing process.

[0010] A further improvement of the technical solution of the present invention is that the banner is made of rubber material, and the cylindrical surface of the banner is provided with a number of pits at equal intervals.

[0011] By adopting the above technical solution, in order to increase the friction between the strip and the drill rod, the strip is made of rubber. When the splicing roller works with the strip to drive the drill rod to rotate, the strip will deform. As the strip deforms, the pits on the surface of the strip will adhere to the drill rod, further enhancing the adhesion between the strip and the drill rod. This allows the splicing roller to work with the strip to rotate the drill rod better, thereby improving the stability and smoothness of the splicing mechanism when splicing the drill rod.

[0012] A further improvement of the technical solution of the present invention is that: the splicing mechanism further includes a downward hydraulic cylinder fixedly installed at the top of the mounting frame, the output end of the downward hydraulic cylinder is fixedly installed with a sliding seat through the side wall of the mounting frame, and a lifting frame is fixedly installed at one end of the sliding seat, a mounting bracket is slidably connected to the bottom end of the lifting frame, a pressure roller is symmetrically rotatably connected to the bottom end of the mounting bracket, and a buffer spring is provided at one end of the mounting bracket, and the buffer spring is sleeved on the bottom end of the lifting frame.

[0013] Using the above technical solution, the controller controls the downward hydraulic cylinder to press down, driving the sliding seat and lifting frame to press down synchronously. This causes the pressure roller on the mounting bracket to press down on the drill rod, making the drill rod and the strip more closely fit. Subsequently, the splicing roller drives the drill rod to move towards the rotary head and thread it with the drill rod on the rotary head. At the same time, the buffer spring is compressed. After the threaded connection between the drill rods is completed, the controller controls the downward hydraulic cylinder to rise, thereby driving the mounting bracket and pressure roller to rise synchronously through the sliding seat and lifting frame. As the pressure roller separates from the surface of the drill rod... As the mounting bracket moves away from the rotary head under the elastic force of the buffer spring, it facilitates subsequent splicing work. The pressure roller can stably press the drill rod onto the splicing roller, increasing the contact area between the drill rod and the strip, and increasing the adsorption force of the strip surface pits on the drill rod, making the drill rod more stable when moving. In addition, during the movement of the drill rod, the mounting bracket can compress the buffer spring, so that the pressure roller can move axially synchronously with the drill rod without overcoming the friction between the pressure roller and the drill rod, further improving the smoothness of the drill rod's movement.

[0014] A further improvement of the technical solution of the present invention is that: the feeding mechanism includes a support frame installed on the upper surface of the mounting base, a feeding frame is fixedly installed at the top of the support frame, an observation frame is provided on the feeding frame, crossbars are symmetrically fixedly installed on the side of the feeding frame near the lifting frame, electric push rods are fixedly installed at the top of the two crossbars, and an extrusion seat is fixedly installed at the output end of one of the electric push rods through the side wall of the crossbar, and the extrusion seat is close to the pressure roller, and a baffle is fixedly installed at the output end of the electric push rod through the side wall of the crossbar.

[0015] Using the above technical solution, to improve the smoothness and speed of drill rod feeding and splicing during the splicing process, a feeding mechanism for rapid feeding is provided on one side of the splicing mechanism. Workers place the drill rods to be used in a row inside the feeding rack. The end of the feeding rack uses an extrusion seat and a baffle to sequentially restrict the feeding of the drill rods. One drill rod is restricted between the extrusion seat and the baffle, while the remaining drill rods are blocked by the baffles within the feeding rack. During feeding, an electric push rod drives the extrusion seat upwards, causing the drill rod between the extrusion seat and the baffle to slide onto the splicing roller. The splicing roller then drives the drill rods to perform the splicing operation. Subsequently... The extrusion seat resets and the baffle rises, allowing the drill rod inside the feed rack to slide between the extrusion seat and the baffle. The baffle then resets, confining one drill rod between the extrusion seat and the baffle, facilitating the next round of feeding. This feeding mechanism further enhances the smoothness and stability of the feeding process. Mechanized feeding replaces manual feeding, improving the speed and safety of drill rod feeding. Furthermore, the feed rack allows for the storage of multiple drill rods, eliminating the need for repeated handling and reducing the splicing time during assembly, thus facilitating drill rod operation.

[0016] A further improvement of the technical solution of the present invention is that: a recycling mechanism is provided on the side of the splicing mechanism away from the feeding mechanism, and the recycling mechanism is fixedly connected to the upper surface of the mounting base. The recycling mechanism includes an inclined rod fixedly installed on the upper surface of the mounting base. A material storage bin is fixedly installed at the top of the inclined rod. An installation rod is fixedly installed at the end of the material storage bin near the lifting frame. A limiting cylinder is fixedly installed at the top of the installation rod. A limiting plate is fixedly installed at the output end of the limiting cylinder through the side wall of the installation rod.

[0017] Using the above technical solution, during the disassembly of the drill rod, the pressure roller presses the drill rod firmly, and then the splicing roller reverses to reverse the drill rod, thus disassembling it. After the drill rod is removed, the pressure roller resets, and then the electric push rod drives the extrusion seat to move downwards again from the position that restricts the drill rod, so that the inclined surface at the bottom of the extrusion seat (the extrusion seat is set in an inverted trapezoidal shape) presses against the side of the drill rod on the splicing roller, thereby squeezing the drill rod off the splicing roller into the storage bin. During this process, the limiting cylinder drives the limiting plate to move upwards, allowing the drill rod to smoothly enter the interior of the storage bin, completing the centralized collection of the drill rod. Through the setting of the recycling mechanism and the mechanized operation mode, the disassembly work can be replaced by manual labor. In addition, the storage function of the storage bin allows the device to work continuously without stopping, further improving the convenience and smoothness of the device during use.

[0018] A further improvement of the technical solution of the present invention is that a support mechanism is provided between the rotary device and the hydraulic clamping unit, and the bottom end of the support mechanism is slidably connected to the cross frame. The support mechanism includes a mounting plate slidably connected to the top of the cross frame. A mounting ring is fixedly installed on the inner ring of the mounting plate. Pressure sensors are fixedly installed at equal intervals on the inner ring of the mounting ring. Adjustment hydraulic cylinders are provided on both sides of the pressure sensors, and the adjustment hydraulic cylinders are fixedly connected to the mounting ring. A cover plate is fixedly installed on one side of the mounting plate.

[0019] Using the above technical solution, when the rotary head drives the drill rod to drill, the hydraulic clamping unit is in a released state. Due to the long length of the drill rod and the long distance between the drill bit and the rotary head, the drill rod may deviate from its drilling position without support. At this time, the drill rod will come into contact with the pressure sensor inside the mounting ring. The pressure sensor will then feed back the actual data to the controller, which will control the adjusting hydraulic cylinder to press the deviated part for preliminary correction. The deviated drill rod will be adjusted in real time so that the drill rod drills according to the preset position, increasing the drilling accuracy and further improving the effectiveness of the device in drilling.

[0020] When splicing drill pipes, the hydraulic clamping unit clamps the drill pipe while the rotary head is released. At this time, the rotary head moves along the crossbeam away from the hydraulic clamping unit. Due to the length of the drill pipe, it only has single-point support from the hydraulic clamping unit, resulting in poor stability. The support mechanism can work with the hydraulic clamping unit to support the drill pipe, further improving the stability of the device's support for the drill pipe. This avoids the increased friction between the end of the drill pipe and the rotary head caused by the single-point support of the hydraulic clamping unit, which would lead to increased wear on the surface of the drill pipe during the rotary head's movement.

[0021] A further improvement of the technical solution of the present invention is that: a transverse hydraulic cylinder is fixedly installed inside the cross frame, the output end of the transverse hydraulic cylinder is threadedly connected to a connecting seat, and the top end of the connecting seat is fixedly connected to the bottom end of the mounting plate.

[0022] Using the above technical solution, when the hydraulic clamping unit clamps the drill rod and the rotary head moves along the crossbeam away from the hydraulic clamping unit, the transverse hydraulic cylinder drives the mounting plate to move synchronously with the rotary head. Subsequently, the rotary head clamps the end of the drill rod. Then, the transverse hydraulic cylinder drives the mounting plate to move quickly towards the hydraulic clamping unit again, cooperating with the hydraulic clamping unit to support the drill rod. By setting the transverse hydraulic cylinder, the support mechanism can be driven to move and support in coordination with the rotary head, so that the drill rod can be effectively supported at different positions at different times during the splicing process. This can improve the docking accuracy of the drill rod during the splicing process and keep the drill rod in a suitable working position at all times.

[0023] A further improvement to the technical solution of the present invention is that a linear bearing is installed on the inner ring of the mounting ring.

[0024] By adopting the above technical solution, the linear bearing can further improve the smoothness of the drill rod sliding inside the support mechanism. At the same time, the linear bearing is easy to replace, improving the convenience of maintenance of the device.

[0025] A further improvement of the technical solution of the present invention is that the pressure value of the pressure sensor is transmitted to the data processing terminal, and the data terminal generates a model curve about the drill pipe and the drill path.

[0026] Using the above technical solution, the pressure sensor can collect and process data in real time based on the deviation of the drill rod, and generate a motion curve of the drill rod tunnel by combining the time and pressure data of the pressure sensor, which facilitates subsequent mining and exploration work.

[0027] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0028] 1. This invention replaces manual splicing with a splicing mechanism, making drill rod splicing more time-saving and labor-saving. Furthermore, the mechanical splicing avoids the safety issues associated with manual splicing, further improving the stability and safety of the device during use. In addition, two symmetrically arranged splicing rollers automatically center the drill rods placed on them, increasing the accuracy of splicing between the two drill rods and further enhancing the reliability of the device during use. This makes it more convenient for operators to use. Moreover, the automated splicing allows for continuous drill rod splicing without stopping the device, accelerating the drilling process.

[0029] 2. This invention increases the friction between the strip and the drill rod by creating pits on the surface of the strip. The strip is made of rubber. When the splicing roller rotates the drill rod in conjunction with the strip, the strip deforms. As the strip deforms, the pits on the surface of the strip adhere to the drill rod, further increasing the adhesion between the strip and the drill rod. This allows the splicing roller to better rotate the drill rod in conjunction with the strip, thereby improving the stability and smoothness of the splicing mechanism when splicing the drill rod, and making the device more convenient for processing.

[0030] 3. The present invention, through the setting of the recycling mechanism and the mechanized operation mode, can replace manual disassembly work. In addition, the storage function of the material storage bin allows the device to work continuously without stopping, further improving the convenience and smoothness of the device during use.

[0031] 4. The present invention, through the setting of the support mechanism, can use the actual data of the pressure sensor to feed back to the adjusting hydraulic cylinder through the controller. The adjusting hydraulic cylinder squeezes the deviated part for preliminary correction, and adjusts the deviated drill rod in real time so that the drill rod can perform drilling processing according to the preset position, thereby increasing the drilling accuracy and further improving the effectiveness of the device in drilling.

Detailed Implementation

[0044] The present invention will be further described in detail below with reference to the embodiments.

[0045] Example 1

[0046] like Figures 1-3 As shown, the present invention provides a mining drilling device with adaptive adjustment, comprising: a mounting base 1, a track drive device 2 for moving a drive device is fixedly mounted on the bottom end of the mounting base 1, a mounting platform 3 is mounted on the top end of the upper surface of the mounting base 1, a hydraulic lifting unit 4 is symmetrically fixedly mounted on the top end of the mounting platform 3, a hydraulic swing unit 5 is fixedly mounted on the output end of the hydraulic lifting unit 4, a crossbeam 6 is fixedly mounted on the working end of the hydraulic swing unit 5, and the top end of the crossbeam 6 near the hydraulic lifting unit 4 is slidably connected... A rotary actuator 7 is connected to drive the drill rod to rotate and feed material. A hydraulic clamping unit 8 is fixedly installed at the top end of the crossbeam 6 away from the rotary actuator 7 for clamping the drill rod. A splicing mechanism 9 is located on the side of the rotary actuator 7 away from the hydraulic clamping unit 8 and is fixedly connected to the upper surface of the mounting base 1 for splicing the drill rod. A feeding mechanism 10 is located on one side of the splicing mechanism 9 and is fixedly connected to the upper surface of the mounting base 1 for feeding the splicing mechanism 9.

[0047] In this embodiment, during the drilling process, the rotary head 7 drives two drill rods that are spliced ​​together to drill. After the first drill rod is drilled into the ore body, the hydraulic clamping unit 8 clamps the connection between the two drill rods. Then, the rotary head 7 moves away from the hydraulic clamping unit 8 to reset. After moving into position, it clamps the drill rod again, and the hydraulic clamping unit 8 releases the clamp on the drill rod. Then, the new drill rod is placed on the splicing mechanism 9, and the splicing mechanism 9 drives the new drill rod to rotate and connect it with the drill rod clamped by the rotary head 7. Then, the rotary head 7 drives the drill rod to rotate and drill. The splicing mechanism 9 can replace the manual splicing method for splicing drill rods, thereby saving time during splicing, reducing the workload of workers, improving the efficiency of the device during splicing, and further improving the smoothness of the device during operation. The hydraulic lifting unit 4 can adjust the processing height of the device in real time, and the hydraulic swing unit 5 can adjust the processing angle of the device accordingly.

[0048] It should be noted that the hydraulic swing unit 5 is composed of a hydraulically driven gear and rack mechanical structure, which is used to drive the crossbeam 6 to rotate, thereby adjusting the working angle of the device and increasing the adjustment range of the drilling angle. In addition, the hydraulic swing unit 5 has a worm gear structure inside. The self-locking form of the worm gear can improve the stability of the crossbeam 6 when swinging at an angle. The rotary device 7 has a hydraulic chuck inside. When it is necessary to clamp the drill rod, the hydraulic chuck clamps and fixes the drill rod to prevent the drill rod from rotating during splicing and drilling, thereby improving the stability of the drill rod during splicing and drilling.

[0049] Example 2

[0050] like Figure 3 and Figure 4 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the splicing mechanism 9 includes a mounting frame 13 fixedly mounted on the upper surface of the mounting substrate 1. A cylinder 14 is fixedly mounted at the bottom end of the mounting frame 13, and a sliding frame 15 is fixedly mounted at the output end of the cylinder 14. The sliding frame 15 and the mounting frame 13 are slidably engaged. Two splicing rollers 16 are symmetrically rotatably connected to the top end of the sliding frame 15. Spiral strips 17 are fixedly mounted on the surfaces of the two splicing rollers 16. A drive belt 19 is fixedly mounted at the end of the sliding frame 15, and the drive belt 19 is fixedly connected to the ends of the two splicing rollers 16 respectively. A drive motor 18 is fixedly mounted at one end of the sliding frame 15, and the output end of the drive motor 18 is engaged with the drive belt 19.

[0051] In this embodiment, during the splicing process of the drill rod using the splicing mechanism 9, a new drill rod is placed on the splicing roller 16. The drive motor 18 drives the two splicing rollers 16 to rotate synchronously in the same direction via the drive belt 19, causing the drill rod placed on the splicing roller 16 to rotate. To increase the placement stability of the drill rod on the splicing roller 16 and the driving stability of the splicing roller 16 on the drill rod, the splicing roller 16 is provided with a strip 17, which can increase the friction between the splicing roller 16 and the drill rod. Furthermore, the spirally arranged strip 17 can drive the drill rod to rotate and provide an axial component force. Thus, the drill rod is driven by the splicing roller 16 and the strip 17 to gradually move towards the drill rod on the rotary device 7, thereby causing the drill rod on the splicing roller 16 to rotate and splice with the drill rod on the rotary device 7, so that the two drill rods can be connected end to end, completing the extension of the drill rod. Then, the rotary device 7... The drill rod is driven to perform drilling operations. The splicing mechanism 9 replaces the manual splicing mode, making the splicing of drill rods more time-saving and labor-saving. Moreover, the mechanical splicing mode can avoid the safety problems of manual splicing mode, further improving the stability and safety of the device during use. In addition, two symmetrically arranged splicing rollers 16 can automatically center the drill rods placed on them, thereby increasing the accuracy between the two drill rods during splicing, further improving the reliability of the device during use, and making it more convenient for operators to use. Furthermore, the automated splicing can continuously splice drill rods without stopping the device, which can speed up the drilling process. In addition, the drill rods can be automatically centered and corrected during feeding, thereby improving the accuracy of the drill rods during splicing, and further improving the stability and smoothness of the splicing process.

[0052] like Figure 4 and Figure 10 As shown, preferably, the banner 17 is made of rubber, and the cylindrical surface of the banner 17 is provided with a number of pits at equal intervals.

[0053] In this embodiment, in order to increase the friction between the strip 17 and the drill rod, the strip 17 is made of rubber. When the splicing roller 16 drives the drill rod to rotate in conjunction with the strip 17, the strip 17 will deform. As the strip 17 deforms, the pits on the surface of the strip 17 will adhere to the drill rod, further enhancing the adhesion between the strip 17 and the drill rod. This allows the splicing roller 16 to better rotate the drill rod in conjunction with the strip 17, thereby improving the stability and smoothness of the splicing mechanism 9 when splicing the drill rod.

[0054] like Figure 4As shown, preferably, the splicing mechanism 9 further includes a downward hydraulic cylinder 20 fixedly installed at the top of the mounting frame 13. The output end of the downward hydraulic cylinder 20 passes through the side wall of the mounting frame 13 and is fixedly installed with a sliding seat 21. A lifting frame 22 is fixedly installed at one end of the sliding seat 21. A mounting bracket 23 is slidably connected to the bottom end of the lifting frame 22. A pressure roller 24 is symmetrically rotatably connected to the bottom end of the mounting bracket 23. A buffer spring 25 is provided at one end of the mounting bracket 23 and is sleeved on the bottom end of the lifting frame 22.

[0055] In this embodiment, the controller controls the downward hydraulic cylinder 20 to press down, causing the sliding seat 21 and the lifting frame 22 to press down synchronously. This causes the pressure roller 24 on the mounting bracket 23 to press down on the drill rod, making the drill rod and the strip 17 fit more closely. Subsequently, the splicing roller 16 drives the drill rod to move towards the rotary unit 7 and to form a threaded connection with the drill rod on the rotary unit 7. At the same time, the buffer spring 25 is compressed. After the threaded connection between the drill rods is completed, the controller controls the downward hydraulic cylinder 20 to rise, thereby causing the mounting bracket 23 and the pressure roller 24 to rise synchronously through the sliding seat 21 and the lifting frame 22. As the pressure roller 24 and the drill rod... When the surface detaches, the mounting bracket 23 will move away from the rotary device 7 under the elastic force of the buffer spring 25, facilitating subsequent splicing work. The pressure roller 24 can stably press the drill rod onto the splicing roller 16, increasing the contact area between the drill rod and the strip 17, and increasing the adsorption force of the pits on the surface of the strip 17 on the drill rod, making the drill rod more stable when moving. In addition, during the movement of the drill rod, the mounting bracket 23 can compress the buffer spring 25, so that the pressure roller 24 can move axially synchronously with the drill rod without overcoming the friction between the pressure roller 24 and the drill rod, further improving the smoothness of the drill rod when moving.

[0056] Example 3

[0057] like Figure 5 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the feeding mechanism 10 includes a support frame 26 mounted on the upper surface of the mounting base plate 1. A feeding frame 27 is fixedly mounted on the top of the support frame 26. An observation frame 28 is provided on the feeding frame 27. Crossbars 29 are symmetrically fixedly mounted on the side of the feeding frame 27 near the lifting frame 22. Electric push rods 30 are fixedly mounted on the top of both crossbars 29. An extrusion seat 31 is fixedly mounted through the side wall of one of the electric push rods 30 and is close to the pressure roller 24. A baffle 32 is fixedly mounted through the side wall of the crossbar 29 at the output end of the electric push rod 30.

[0058] In this embodiment, to improve the smoothness and speed of the drill rod feeding and splicing process during splicing, a feeding mechanism 10 for rapid feeding is provided on one side of the splicing mechanism 9. The operator places the drill rods to be used in a row inside the feeding rack 27. The end of the feeding rack 27 is used to sequentially restrict the feeding of the drill rods via an extrusion seat 31 and a baffle 32. One drill rod is restricted between the extrusion seat 31 and the baffle 32, while the remaining drill rods are blocked by the baffle 32 within the feeding rack 27. During feeding, the electric push rod 30 drives the extrusion seat 31 to move upwards, causing the drill rod between the extrusion seat 31 and the baffle 32 to slide onto the splicing roller 16. The splicing roller 16 then drives the drill rods to perform the splicing work. Subsequently, the extrusion seat 31 is reset, and the baffle 32 is raised, allowing the drill rod inside the feed rack 27 to slide between the extrusion seat 31 and the baffle 32. Then, the baffle 32 is reset, confining one drill rod between the extrusion seat 31 and the baffle 32, facilitating the next round of feeding. The feeding mechanism 10 further improves the feeding smoothness and stability of the device. Replacing manual feeding with mechanized feeding can improve the speed and safety of drill rod feeding. In addition, the feed rack 27 can store multiple drill rods without having to repeatedly move them, further reducing the splicing time during the splicing process and facilitating the drilling operation of the device.

[0059] like Figure 6 As shown, preferably, the splicing mechanism 9 is provided with a recycling mechanism 11 on the side away from the feeding mechanism 10, and the recycling mechanism 11 is fixedly connected to the upper surface of the mounting base plate 1. The recycling mechanism 11 includes an inclined rod 33 fixedly installed on the upper surface of the mounting base plate 1. A material storage bin 34 is fixedly installed at the top of the inclined rod 33. An installation rod 35 is fixedly installed at the end of the material storage bin 34 near the lifting frame 22. A limiting cylinder 36 is fixedly installed at the top of the installation rod 35. A limiting plate 37 is fixedly installed at the output end of the limiting cylinder 36 through the side wall of the installation rod 35.

[0060] In this embodiment, when disassembling the drill rod, the pressure roller 24 presses the drill rod, and the splicing roller 16 reverses to reverse the drill rod, thus disassembling it. After the drill rod is removed, the pressure roller 24 resets, and then the electric push rod 30 drives the extrusion seat 31 to move down again from the position that restricts the drill rod, so that the inclined surface at the bottom of the extrusion seat 31 (the extrusion seat 31 is set in an inverted trapezoidal shape) presses against the side of the drill rod on the splicing roller 16, thereby squeezing the drill rod off the splicing roller 16 into the storage bin 34. During this process, the limiting cylinder 36 drives the limiting plate 37 to move up, so that the drill rod can smoothly enter the interior of the storage bin 34, completing the centralized collection of the drill rod. Through the setting of the recycling mechanism 11, the mechanized operation mode can replace manual disassembly. In addition, the storage function of the storage bin 34 allows the device to work continuously without stopping, further improving the convenience and smoothness of the device during use.

[0061] Example 4

[0062] like Figures 7-9 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, a support mechanism 12 is provided between the rotary device 7 and the hydraulic clamping unit 8, and the bottom end of the support mechanism 12 is slidably connected to the cross frame 6. The support mechanism 12 includes a mounting plate 38 slidably connected to the top end of the cross frame 6. A mounting ring 41 is fixedly installed on the inner ring of the mounting plate 38. Pressure sensors 43 are fixedly installed at equal intervals on the inner ring of the mounting ring 41. Adjusting hydraulic cylinders 44 are provided on both sides of the pressure sensors 43, and the adjusting hydraulic cylinders 44 are fixedly connected to the mounting ring 41. A cover plate 42 is fixedly installed on one side of the mounting plate 38.

[0063] In this embodiment, when the rotary head 7 drives the drill rod to drill, the hydraulic clamping unit 8 is in a released state. Due to the long length of the drill rod and the long distance between the drill bit and the rotary head 7, the position of the drill rod in drilling will deviate without support. At this time, the drill rod will make squeezing contact with the pressure sensor 43 inside the mounting ring 41. The pressure sensor 43 feeds back the actual data to the controller, which controls the adjusting hydraulic cylinder 44 to squeeze the deviated part for preliminary correction. The deviated drill rod is adjusted in real time so that the drill rod drills according to the preset position, increasing the drilling accuracy and further improving the effectiveness of the device in drilling.

[0064] When splicing drill rods, the hydraulic clamping unit 8 clamps the drill rod while the rotary head 7 is released. At this time, the rotary head 7 moves along the crossbeam 6 away from the hydraulic clamping unit 8. Due to the length of the drill rod, it only has single-point support from the hydraulic clamping unit 8, resulting in poor stability. The support mechanism 12 can cooperate with the hydraulic clamping unit 8 to support the drill rod, further improving the stability of the device's support for the drill rod. This avoids the single-point support from the hydraulic clamping unit 8 causing increased friction between the end of the drill rod and the rotary head 7, which would lead to increased wear on the surface of the drill rod during the movement of the rotary head 7.

[0065] like Figures 7-9 As shown, preferably, a transverse hydraulic cylinder 39 is fixedly installed inside the transverse frame 6, and the output end of the transverse hydraulic cylinder 39 is threadedly connected to a connecting seat 40, and the top end of the connecting seat 40 is fixedly connected to the bottom end of the mounting plate 38.

[0066] In this embodiment, when the hydraulic clamping unit 8 clamps the drill rod and the rotary head 7 moves along the crossbeam 6 away from the hydraulic clamping unit 8, the transverse hydraulic cylinder 39 drives the mounting plate 38 to move synchronously with the rotary head 7. Subsequently, the rotary head 7 clamps the end of the drill rod. Then, the transverse hydraulic cylinder 39 drives the mounting plate 38 to move quickly towards the hydraulic clamping unit 8, cooperating with the hydraulic clamping unit 8 to support the drill rod. The transverse hydraulic cylinder 39 can drive the support mechanism 12 to move and support in coordination with the rotary head 7, so that the drill rod can be effectively supported at different positions at different times during the splicing process, which can improve the docking accuracy of the drill rod during the splicing process and keep the drill rod in a suitable working position.

[0067] like Figures 7-9 As shown, preferably, a linear bearing 45 is mounted on the inner ring of the mounting ring 41.

[0068] In this embodiment, the linear bearing 45 can further improve the smoothness of the drill rod sliding inside the support mechanism 12. At the same time, the linear bearing 45 is easy to replace, improving the convenience of the device during maintenance.

[0069] like Figure 9 As shown, preferably, the pressure value of the pressure sensor 43 is transmitted to the data processing terminal, and the data terminal generates a model curve about the drill pipe and the drill path.

[0070] In this embodiment, the pressure sensor 43 can collect and process data in real time based on the deviation of the drill pipe, and generate a motion curve of the drill pipe tunnel by combining the time and the pressure data of the pressure sensor 43, which facilitates subsequent mining and exploration work.

[0071] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
