An energy-saving mining drilling rig

Abstract

This invention relates to an energy-saving mining drilling rig in the field of drilling equipment. It uses a fixed ring on the drill rod and a sliding ring, spring, and pressure sensor installed in the sleeve to monitor the axial pressure on the drill rod in real time. By adjusting the first lead screw module to control the position of the drill rod, the axial pressure on the drill rod is kept within a set axial pressure threshold range, reducing the probability of bending deformation of the drill rod, reducing friction between the drill rod and drill bit and the borehole wall, thereby reducing drill vibration, improving cutting efficiency, and reducing energy consumption. Simultaneously, by incorporating a sliding shaft, a prismatic worm gear ring, and a worm, the power structure of the drill tool and the driving drill tool achieves sliding transmission, replacing the traditional rigid connection between the drill tool and the drive mechanism. This slows down the increase in axial pressure on the drill rod, providing more adjustment time for the controller to adjust the axial pressure of the drill rod, reducing the speed of axial bending deformation of the drill rod, and protecting the drill rod.

Description

Technical Field

[0001] This invention relates to a drilling device, and more particularly to an energy-saving mining drilling rig used in the field of drilling equipment. Background Technology

[0002] Mining drill rigs are core equipment in mining and tunnel engineering, mainly used for drilling blast holes, water exploration holes, or anchoring holes in rock formations. They drive the drill rod to rotate at high speed and apply axial pressure through hydraulic or electric systems, which in turn drives the drill bit to break the rock. During drilling, the drill rod, as a key component for power transmission and load bearing, is continuously subjected to axial loads from the drilling rig. However, when the drilling pressure is too high or the rock conditions are complex, the drill rod is prone to axial bending or helical buckling deformation (self-torsional deformation). The contact area between the deformed drill rod and the inner wall of the borehole increases, resulting in a significant increase in frictional resistance. At the same time, the geometric instability of the drill rod can cause severe vibration. This nonlinear energy consumption not only reduces drilling efficiency but also forces the power system to output additional energy to overcome friction and vibration losses, exacerbating equipment wear and shortening the life of the drill bit.

[0003] A patent with publication number CN102678046B discloses a mining drilling rig. In this rig, the pump station, drill arm mechanism, and drilling mechanism are all mounted on a single traveling mechanism. The pump station is guided by a sliding mechanism at its bottom, which engages with a guide rail on the traveling mechanism. When the rig needs to be moved, the operator can control the traveling mechanism to move the pump station, drill arm mechanism, and drilling mechanism as a whole to the work site. Then, by controlling the sliding mechanism, the pump station is slid away from the drill arm mechanism until its rear end is near the edge of the traveling mechanism. This gives the rig a structure similar to a split-type rig in the work area. Furthermore, because the sliding device's slide seat engages with the guide rail on the traveling mechanism via a dovetail groove, the problem of the pump station tipping off the traveling mechanism due to uneven terrain in the mine is avoided during the rig's movement.

[0004] The aforementioned prior art discloses a technical solution to the problem of drilling rigs easily overturning in pits and depressions, but it does not solve the problem of increased energy consumption of drilling rigs caused by drill rod deformation. Summary of the Invention

[0005] The technical problem to be solved by the present invention in view of the above-mentioned prior art is the problem of increased energy consumption of drilling rig due to increased deformation of drill pipe under stress.

[0007] A fixed ring is fixedly connected to the side of the drill pipe near the sliding shaft. A sleeve fixedly connected to the power box is slidably sleeved on the outside of the fixed ring. A spring is installed inside the sleeve. Sliding rings that slide against the inner wall of the sleeve are fixedly connected to both sides of the spring. The sliding ring on the left side of the spring abuts against the fixed ring, and the sliding ring on the right side of the spring abuts against the detection end of the pressure sensor. The non-detection end of the pressure sensor is fixedly connected to the inner wall of the sleeve. The pressure sensor is used to detect the axial pressure received by the drill pipe. The first lead screw module, the second motor, and the pressure sensor are all connected to the same controller.

[0008] In the aforementioned energy-saving mining drilling rig, the axial pressure of the drill rod is monitored and adjusted in real time through springs, pressure sensors, and sliding shafts, thereby reducing the probability of drill rod deformation.

[0009] As a further improvement of this application, a torsion monitoring mechanism is provided inside the drill pipe. The torsion monitoring mechanism includes a detection rod inserted into the central axis of the drill pipe. A first infrared distance sensor with linear equidistant distribution is fixedly connected inside the detection rod. A reflective block is fixedly connected to the inner wall of the drill pipe and is arranged opposite to the first infrared distance sensor. The reflective block is opposite to the first infrared distance sensor and the reflective surface used to reflect light is a spiral surface.

[0010] As a further improvement of this application, a pre-inspection mechanism is also included. The pre-inspection mechanism includes a second infrared distance sensor disposed directly above the drill rod. The second infrared distance sensor is fixedly connected to a second lead screw module that drives it to move along the axial direction of the drill rod. The second lead screw module is fixedly connected to a second slot frame. The second slot frame is fixedly connected to a guide block. The guide block has a guide hole for the drill rod to pass through. The guide block is fixedly connected to a first slot frame. The second infrared distance sensor and the second lead screw module are both connected to a controller. The controller is equipped with an alarm module. The output terminal of the alarm module is connected to a buzzer. The controller and the buzzer are both fixedly connected to a movable base.

[0011] As a further improvement of this application, the adjusting frame includes a base fixedly connected to the movable seat, a rotating platform rotatably connected to the base, an output shaft of a first motor fixedly connected to the rotating platform, and the first motor fixedly nested inside the base; a hinge rod is fixedly connected to the rotating platform, the upper end of the hinge rod is hinged to the first slot frame, and a fixed end of a hydraulic cylinder is hinged to the side of the rotating platform away from the hinge rod, and the movable end of the hydraulic cylinder is hinged to the first slot frame.

[0012] As a further improvement of this application, the detection rod is provided with a receiving groove for accommodating the first infrared distance sensor, the drill rod is provided with an axial cavity for inserting the detection rod, the inner wall of the axial cavity is provided with a mounting groove for accommodating the reflector block, and the detection rod extends to the outside of the sliding shaft and is fixedly connected to the sliding shaft.

[0013] As a further improvement of this application, a guide cylinder is fixedly connected inside the guide hole. The guide cylinder is slidably sleeved on the outside of the drill rod and fixedly connected to the guide block by bolts.

[0014] As a further improvement of this application, a brushing cylinder is provided on the side of the guide block away from the power box and sleeved on the outside of the drill rod. The brushing cylinder is open and funnel-shaped and has bristles fixedly connected to its inner wall. A toothed ring is fixedly connected to the brushing cylinder. The toothed ring is rotatably connected to the guide block. The toothed ring meshes with a drive gear. The drive gear is fixedly connected to the output shaft of a third motor. The third motor is fixedly connected to the guide block.

[0015] In summary, this invention, through a fixed ring on the drill rod and a sliding ring, spring, and pressure sensor installed in the sleeve, monitors the axial pressure on the drill rod in real time during drilling. By adjusting the first lead screw module to control the position of the drill rod, the axial pressure on the drill rod is kept within a set axial pressure threshold range, reducing the probability of bending deformation of the drill rod, reducing friction between the drill rod and drill bit and the hole wall, thereby reducing drill tool (drill bit and drill rod) vibration, improving cutting efficiency, and reducing energy consumption. Simultaneously, by incorporating a sliding shaft, a prismatic worm gear ring, and a worm, the power structure of the drill tool and the driving drill tool achieves sliding transmission. When the drill bit encounters a hard rock wall, it can drive the drill rod to slide laterally, replacing the traditional rigid connection between the drill tool and the drive mechanism. This slows down the increase in axial pressure on the drill rod, providing more adjustment time for the controller to adjust the axial pressure of the drill rod, reducing the bending deformation rate of the drill rod, and protecting the drill rod.

Detailed Implementation

[0029] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0030] Implementation method 1:

[0031] Figure 1-8An energy-saving mining drilling rig is shown, including a movable base 1, an adjusting frame 2 fixedly connected to the movable base 1, a drilling mechanism 3 fixedly installed on the adjusting frame 2, the drilling mechanism 3 including a drill rod 8, a drill bit fixedly connected to the front end of the drill rod 8, a sliding shaft 7 fixedly connected to the rear end of the drill rod 8, a power box 6 slidably passing through the sliding shaft 7, a first lead screw module 5 fixedly connected to the power box 6, the first lead screw module 5 installed in a first slot frame 4, the first lead screw module 5 drives the power box 6 and the drill rod 8 to move along the first slot frame 4, realizing the drilling of the drill rod 8;

[0032] Please see Figure 3 and Figure 4 The power box 6 is equipped with a prismatic cylinder 10 that is slidably engaged with the sliding shaft 7. The prismatic cylinder 10 is rotatably connected to a support plate 601 that is fixedly connected to the inner wall of the power box 6. A worm gear ring 11 is fixedly connected to the outer side of the prismatic cylinder 10. The worm gear ring 11 is engaged with a worm 12. The worm 12 is fixedly connected to the output shaft of a second motor 13. The second motor 13 is fixedly connected to the outer wall of the power box 6. The second motor 13 drives the prismatic cylinder 10 to rotate through the worm 12 and the worm gear ring 11. The prismatic cylinder 10 drives the sliding shaft 7 to rotate. The sliding shaft 7 drives the drill rod 8 to rotate. The drill rod 8 drives the drill bit to rotate, thereby performing rotational cutting on the rock wall.

[0033] Please see Figure 3 and Figure 4 A fixing ring 801 is fixedly connected to the side of the drill rod 8 near the sliding shaft 7. A sleeve fixedly connected to the power box 6 is slidably sleeved on the outside of the fixing ring 801. A spring 14 is provided inside the sleeve. Sliding rings 15 that slide against the inner wall of the sleeve are fixedly connected to both sides of the spring 14. The sliding ring 15 on the left side of the spring 14 abuts against the fixing ring 801. The sliding ring 15 on the right side of the spring 14 abuts against the detection end of the pressure sensor 16. The non-detection end of the pressure sensor 16 is fixedly connected to the inner wall of the sleeve. The pressure sensor 16 is used to detect the axial pressure received by the drill rod 8. The first lead screw module 5, the second motor 13 and the pressure sensor 16 are all connected to the same controller.

[0034] Specifically, when the drill bit contacts the rock wall, as the drill rod 8 drills, the drill bit is squeezed by the rock wall, and the drill bit transmits the squeezing force to the drill rod 8. The fixed ring 801 on the drill rod 8 slides in the sleeve and squeezes the sliding ring 15 on the side closest to it. The sliding ring 15 on the side closest to the fixed ring 801 squeezes the sliding ring 15 on the side closest to the pressure sensor 16 through the spring 14. The sliding ring 15 on the side closest to the pressure sensor 16 squeezes the pressure sensor 16. Therefore, the axial pressure of the drill rod 8 can be monitored in real time through the pressure sensor 16.

[0035] In addition, during drilling operations, the controller starts the second motor 13 and the first lead screw module 5. The drill rod 8 drives the drill bit to rotate, cutting the rock wall. The first lead screw module 5 drives the drill rod 8 to move towards the rock wall, drilling the drill rod 8. During the drilling process, the axial pressure of the drill rod 8 is monitored in real time by the pressure sensor 16. When the drill bit encounters a hard rock wall, the spring 14 is compressed, and the axial pressure of the drill rod 8 gradually increases. However, when the axial pressure on the drill rod 8 exceeds the set axial pressure threshold range, the controller controls the first lead screw module 5 to reverse, so that the drill rod 8 and the drill bit move in opposite directions until the axial pressure on the drill rod 8 is within the set axial pressure threshold range. Then, the controller controls the first lead screw module 5 to rotate forward again to carry out the drilling operation.

[0036] Compared to traditional mining drills, this invention, through a fixed ring 801 on the drill rod 8 and a sliding ring 15, spring 14, and pressure sensor 16 installed in the sleeve, monitors the axial pressure on the drill rod 8 in real time during drilling. By adjusting the first lead screw module 5, the position of the drill rod 8 is controlled, ensuring that the axial pressure on the drill rod 8 is within a set axial pressure threshold range. This reduces the probability of bending deformation of the drill rod 8, reduces friction between the drill rod 8 and the drill bit and the hole wall, thereby reducing drill tool (drill bit and drill rod 8) vibration, improving cutting efficiency, and reducing energy consumption. Simultaneously, by providing a sliding shaft 7, a prism cylinder 10, a worm gear ring 11, and a worm 12, the power structure of the drill tool and the driving drill tool achieves sliding transmission. When the drill bit encounters a hard rock wall, it can drive the drill rod 8 to slide laterally, replacing the traditional rigid connection between the drill tool and the driving mechanism. This slows down the increase in axial pressure on the drill rod 8, providing more adjustment time for the controller to adjust the axial pressure of the drill rod 8, reducing the bending deformation rate of the drill rod 8, and protecting the drill rod 8.

[0037] Please see Figure 1 and Figure 2 The adjusting frame 2 includes a base 201 fixedly connected to the movable seat 1. The base 201 is rotatably connected to a rotating platform 202. The rotating platform 202 is fixedly connected to the output shaft of a first motor 203. The first motor 203 is fixedly nested inside the base 201. A hinge rod 204 is fixedly connected to the rotating platform 202. The upper end of the hinge rod 204 is hinged to the first slot frame 4. The fixed end of a hydraulic cylinder 205 is hinged to the side of the rotating platform 202 away from the hinge rod 204. The movable end of the hydraulic cylinder 205 is hinged to the first slot frame 4.

[0038] Specifically, the first motor 203 drives the rotating table 202 to rotate, thereby adjusting the horizontal orientation of the drill rod 8. The hydraulic cylinder 205 pushes the first slot frame 4 to rotate, thereby adjusting the vertical orientation of the drill rod 8, thus realizing the adjustment of the three-dimensional orientation of the drill rod 8. It should be noted that both the first motor 203 and the hydraulic cylinder 205 are connected to the controller.

[0039] Please see Figure 2 and Figure 6-8 The drill pipe 8 is equipped with a torsion monitoring mechanism, which includes a detection rod 18 inserted into the central axis of the drill pipe 8. A first infrared distance sensor 19 is fixedly connected inside the detection rod 18 and is linearly and equidistantly distributed. A reflective block 20 is fixedly connected to the inner wall of the drill pipe 8 and is disposed opposite to the first infrared distance sensor 19. The reflective block 20 is opposite to the first infrared distance sensor 19 and the reflective surface used to reflect light is a spiral surface.

[0040] Specifically, the reflective surface of the reflective block 20 is a spiral surface. When the drill rod 8 undergoes torsional deformation, the drill rod 8 causes the reflective block 20 to rotate relative to the first infrared distance sensor 19. The real-time distance between the first infrared distance sensor 19 and the reflective surface changes. The torsion angle of the drill rod 8 corresponds one-to-one with the distance between the first infrared distance sensor 19 and the reflective surface, thereby obtaining the degree of torsional deformation of the drill rod 8.

[0041] When the torsion angle of drill rod 8 exceeds the set torsion angle threshold range, the controller controls the second motor 13 to reduce the speed, thereby reducing the drill rod torque and reducing the torsional deformation of drill rod 8. When the speed of the second motor 13 is reduced to the set minimum drilling speed, if the torsion angle is still within the set torsion angle threshold range within the set time, the controller starts the first lead screw module 5 to perform the rod retraction operation to protect drill rod 8.

[0042] Please see Figure 7 The detection rod 18 has a receiving groove 1801 for accommodating the first infrared distance sensor 19. The drill rod 8 has an axial cavity for inserting the detection rod 18. The inner wall of the axial cavity has a mounting groove 802 for accommodating the reflector block 20. The detection rod 18 extends to the outside of the sliding shaft 7 and is fixedly connected to the sliding shaft 7.

[0043] The second implementation method:

[0044] Figure 9-11 An energy-saving mining drill rig is shown. Based on the first embodiment, it further includes a pre-inspection mechanism. The pre-inspection mechanism includes a second infrared distance sensor 21 located directly above the drill rod 8. The second infrared distance sensor 21 is fixedly connected to a second lead screw module 22 that drives it to move along the axial direction of the drill rod 8. The second lead screw module 22 is fixedly connected to a second slot frame 23. The second slot frame 23 is fixedly connected to a guide block 9. The guide block 9 has a guide hole for the drill rod 8 to pass through. The guide block 9 is fixedly connected to a first slot frame 4. The second infrared distance sensor 21 and the second lead screw module 22 are both connected to a controller. The controller is equipped with an alarm module. The output end of the alarm module is connected to a buzzer. The controller and the buzzer are both fixedly connected to a movable base 1 (not shown in the figure).

[0045] An energy-saving mining drilling rig includes the following steps during use:

[0046] Step 1: The controller starts the second motor 13, and the drill rod 8 rotates in a circular motion.

[0047] Step 2: The controller activates the second infrared distance sensor 21 and the second lead screw module 22. The second infrared distance sensor 21 detects the circumferential sidewall of the rotating drill rod 8. The second lead screw module 22 drives the second infrared distance sensor 21 to move intermittently until the second infrared distance sensor 21 measures the circumferential sidewall of the entire drill rod 8.

[0048] Step 3: During the measurement process, when the distance to the drill rod 8 measured by the second infrared distance sensor 21 is not equal to the set distance threshold range, the controller will activate the buzzer to sound an alarm.

[0049] Specifically, the drill rod 8 has a cylindrical structure. When the drill rod 8 is intact and undeformed, or when the deformation is less than the set deformation, the real-time distance value measured by the second infrared distance sensor 21 during the detection process should be within the set distance threshold range. By detecting the drill rod 8, the drilling quality is improved and energy consumption is reduced. It should be noted that when the drill rod 8 deviates horizontally, the measured real-time distance value is also not within the set distance threshold range. The reasons for the horizontal deviation of the drill rod 8 include, but are not limited to, the following: 1. Excessive wear at the rotating contact point between the drill rod 8 and the guide block 9 or sleeve; 2. Malfunction or change in position of the second infrared distance sensor 21. All of the above-listed reasons require manual inspection.

[0050] Please see Figure 9 A guide cylinder 17 is fixedly connected inside the guide hole. The guide cylinder 17 is slidably sleeved on the outside of the drill rod 8 and fixedly connected to the guide block 9 by bolts.

[0051] Specifically, by providing a guide cylinder 17, the drill rod 8 has better straightness, improving the stability of the drill rod 8 and the drill bit, improving the straightness of the drill rod 8 during inspection, improving the accuracy of inspection, and facilitating the replacement of the guide cylinder 17.

[0052] Please see Figure 9 and Figure 11 A brushing cylinder 24 is provided on the side of the guide block 9 away from the power box 6 and is sleeved on the outside of the drill rod 8. The brushing cylinder 24 is open-mouthed and funnel-shaped, and brush bristles 2401 are fixedly connected to the inner wall. A toothed ring 25 is fixedly connected to the brushing cylinder 24. The toothed ring 25 is rotatably connected to the guide block 9. The toothed ring 25 meshes with a drive gear 26. The drive gear 26 is fixedly connected to the output shaft of the third motor 27. The third motor 27 is fixedly connected to the guide block 9.

[0053] Specifically, the third motor 27 drives the gear ring 25 to rotate via the drive gear 26. The gear ring 25 drives the brushing cylinder 24 to rotate, which brushes and cleans the residual slag on the surface of the drill rod 8, reducing the interference of residual debris on the second infrared distance sensor 21. This facilitates the detection of the drill rod 8 after each drilling, reduces the probability of deformed drill rod 8 operating, and lowers the overall energy consumption.

[0054] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
