Description

Technical Field

[0001] The present invention relates to the technical field of mine mining, in particular to a drilling direction guiding device of a drilling rig used for mine mining. Background Art

[0002] In the process of mining operations, drilling operations are inevitable. When the depth of the hole to be drilled is high, the length of the drill rod is also correspondingly long, which can easily cause circumferential runout during the initial drilling and the drilling process, resulting in hole angle deviation or inaccurate size. For this reason, some direction guiding devices are needed to guide the drill rod. The Chinese utility model patent application number 202421589819.1 provides a drilling direction guiding device for a drilling rig for mining. The device "several guide rollers limit drill rods of different specifications from different directions to avoid the drill rod from moving during drilling; at the same time, the first motor drives the flip ring to rotate to adjust the direction of the drill rod. The angle of the flip ring is adapted to the drilling angle of the drill rod of the drilling rig, thereby guiding the drill rod during the drilling process. "It has the following four shortcomings. First, the guide roller of the device is in a parallel state with the drill rod as shown in the attached figure, and the trajectory of the drill rod during drilling is spiral, so there is axial sliding friction between the guide roller and the guide roller. If the guide roller has a good clamping and limiting effect on the drill rod, it means that the friction force is greater, which not only hinders the axial movement of the drill rod, but also increases the wear of the guide roller and reduces the service life. If the clamping effect is reduced, although the above problems can be solved, the limiting and guiding effects on the drill rod will be reduced; second, the device is relatively limited in adjusting the angle of the drill rod and cannot perform XYZ The angle adjustment in the three axial directions is not flexible and convenient to use. Thirdly, the device lacks a corresponding lifting mechanism. During the initial drilling process, the drill bit is close to the mine surface. At this time, the clamping position should be upward to clamp the drill rod. When the drill bit is fully entered into the hole, the clamping position should be lowered and closer to the mine surface, thereby facilitating construction while ensuring the limiting effect of the drill rod. Fourthly, the device lacks a corresponding cleaning structure. During the drilling process, the surface of the drill rod is inevitably contaminated with mud, dust and other debris due to problems in the early or later stages. If it is not cleaned, it will affect the rolling friction between the outer wall of the drill rod and the guide roller, thereby affecting the limiting effect. These highlights the shortcomings of the existing technology. Summary of the Invention

When current in different directions is passed through the electromagnet, it can magnetically attract and magnetically repel the permanent magnet, so that the sliding cylinder slides back and forth along the guide plate. The speed control motor and the electromagnet are electrically connected to the electronic control system respectively.

[0010] On the basis of the above technical solution, the cleaning mechanism includes a No. 1 electric push rod, a support rod, a No. 3 support, a pulley, a steel belt, and a shield. Three horizontal No. 1 electric push rods are fixed at equal angles on the top circumference of the base, and three vertical support rods are fixed at equal angles on the top circumference. Each of the support rods and each No. 1 electric push rod is radially horizontally corresponding to the perforation. Each No. 1 electric push rod is radially concentrically arranged compared to the perforation, and the ends of the push rods away from the perforations are respectively fixed with vertical and different There are three supports of different heights, and each of the three supports is rotatably connected to a pulley.

In this way, the drill rod can be clamped and limited at a position closer to the drill hole both in the early stage of drilling and after the drill bit has fully entered the hole, thereby improving the guiding effect of the drill rod. By controlling the No. 2 linear reciprocating hydraulic cylinder to extend to different degrees through the hydraulic system, the top seat can be used to touch the support seat to different degrees. Then, the angle of the support seat relative to the base in the three axial directions of XYZ can be adjusted under the rotation connection between the spherical shell and the spherical protrusion, so as to better adapt to the angle of the drill rod relative to the base, making the drilling operation more convenient and faster. The cleaning mechanism can clean the outer walls of the drill rod on the upper and lower sides of the contact roller, reducing interference with the contact between the contact roller and the drill rod, improving the guiding effect, and intercepting debris or mud and sand ejected during the drilling process to a certain extent, making it safer and reducing the amount of diffusion along the drill rod, thereby reducing pollution to the drill rod and reducing the adverse effects on the drill rod guidance.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-6As shown, a drilling direction guiding device for a drilling rig used in mining comprises a base 1, a through hole 2, a locking mechanism, and an electronic control system 19. The base 1 is penetrated by a through hole 2 in the middle part, and a locking mechanism is fixed on the top. The base 1 is penetrated by a plurality of mounting holes 4 in the upper and lower parts. A support seat 5 is installed on the upper part of the locking mechanism. Three No. 1 supports 6 are fixed at equal angles on the circumference of the support seat 5, and a through hole 7 is penetrated by the upper and lower parts. The through hole 7 can be coaxial with the through hole 2. A horizontal hydraulic cylinder body 8 is fixed to each of the No. 1 supports 6. The hydraulic cylinder body 8 is radially arranged compared to the through hole 7. A sealing piston 9 is sealed and horizontally slidably connected in each of the hydraulic cylinder bodies 8, and the ends away from the through hole 7 are fixedly connected with an oil port 10. The sealing piston 9 can also rotate in the hydraulic cylinder body 8. The ends of the sealing pistons 9 close to the through hole 7 are respectively fixed with hydraulic rods 11 parallel to the hydraulic cylinder body 8. The bevel gears 12 are axially slidably connected to each other, and roller frames 13 are fixed to the axial ends near the through holes 7. Each of the roller frames 13 is rotatably connected to a contact roller. A rotating sleeve 15 is fixed to the end of each bevel gear 12 near the hydraulic cylinder body 8. Each rotating sleeve 15 is rotatably connected to the hydraulic cylinder body 8. The hydraulic cylinder body 8, rotating sleeve 15, bevel gear 12 and hydraulic rod 11 are coaxial. The outer circumference of the contact roller is made of rubber. The support seat 5 is rotatably connected to the vertical rotating cylinder 16 and is fixed with a rotating drive mechanism with a braking function. A bevel gear ring 18 is coaxially fixed to the outside of the rotating cylinder 16 and is driven to rotate and brake by the rotating drive mechanism. The bevel gear ring 18 is meshed with each bevel gear 12. Each of the oil ports 10 is respectively connected to the external hydraulic system. The electronic control system 19 is externally powered. The electronic control system is a known prior art, such as a single-chip microcomputer, a PLC and an industrial computer.

[0023] During use, the base 1 is fixed to the position to be drilled using mounting holes 4 with external bolts or other fasteners, so that the through-hole 2 corresponds to the point to be drilled. The drill rod is then passed through the through-hole 7 and aligned coaxially. Hydraulic oil is then injected into the oil port 10, causing the pistons, hydraulic rod 11, roller frame 13, and contact roller to move toward the drill rod, so that the contact roller contacts the outer wall of the drill rod, achieving rolling friction. During this process, according to the spiral trajectory of the drill rod drilling, the rotary drive mechanism is controlled to drive the rotating cylinder 16 to rotate appropriately and then brake. The bevel gear ring 18 and bevel gear 12 can then be used to rotate the hydraulic rod 11, sealing piston 9, and roller frame 13, thereby adjusting the inclination angle of the contact roller relative to the drill rod, so that the axial direction of the contact roller is perpendicular to the spiral trajectory. At this time, when the drill rod is drilling, the rotation direction of the contact roller can be decomposed into horizontal and vertical directions, thereby greatly reducing the obstruction to the drilling of the drill rod and reducing its own wear, while ensuring the clamping and limiting effect of the drill rod, that is, improving the guiding effect of the drill rod.

[0024] The contact roller includes a roller shaft 20, a roller plate 21, a roller sleeve 22, a No. 1 tension spring 23, and a filler 24. The roller frame 13 is rotatably connected to the roller shaft 20. The radial roller plates 21 are respectively fixed at both axial ends of the roller shaft 20. A No. 1 tension spring 23 is commonly fixed between the roller plates 21 at both ends of the same roller shaft 20. A roller sleeve 22 is commonly fixed between the roller plates 21 at both ends of the same roller shaft 20. The roller sleeve 22 is made of rubber. The roller sleeve 22 is gap-inserted outside the No. 1 tension spring 23. The No. 1 tension spring 23 is gap-inserted outside the roller shaft 20. The enclosed space formed by the roller sleeve 22 and the roller plate 21 is filled with a filler 24. The filler 24 is a granular, non-flammable and non-explosive solid.

[0025] The filler 24 can ensure that the roller sleeve 22 is in full contact with the drill rod, thereby increasing the contact area. The elastic tension of the No. 1 tension spring 23 can make the contact roller tend to restore a regular roller structure, thereby applying a repulsive force to the drill rod. Under the combined action of the two, the limit clamping effect of the drill rod is improved, making the rotation of the drill rod more stable and reducing circumferential runout.

[0026] The rotation drive mechanism includes a servo motor 25, a gear 26, an outer gear ring 27, and an inclination sensor 28. The support seat 5 is fixed with a servo motor 25 parallel to the axial direction of the rotating cylinder 16. The rotating shaft of the servo motor 25 is coaxially fixed with a gear 26 and has a braking function. The rotating cylinder 16 is coaxially fixed with an outer gear ring 27, and the gear 26 is engaged with the outer gear ring 27. Each of the roller frames 13 is respectively fixed with an inclination sensor 28. Each of the inclination sensors 28 and the servo motor 25 is respectively electrically connected to the electronic control system 19. The inclination sensor 28 is used to measure the angle between the roller frame 13 and the virtual axis of the through hole 7 in the vertical plane.

[0027] By controlling the servo motor 25 to rotate, the gear 26 is engaged with the outer gear ring 27 to drive the rotating cylinder 16 to rotate, and the inclination sensor 28 is used to measure the angle between the roller frame 13 and the virtual axis of the through hole 7, that is, the drill rod in the vertical plane, so as to maintain perpendicularity to the spiral trajectory of the drill rod.

[0028] The locking mechanism includes a No. 1 linear reciprocating hydraulic cylinder 29, a lifting seat 30, and an angle adjustment mechanism. Multiple vertical No. 1 linear reciprocating hydraulic cylinders 29 are fixed at equal angles on the top circumference of the base 1. The top of the piston rod of each No. 1 linear reciprocating hydraulic cylinder 29 is commonly fixed with a lifting seat 30. The lifting seat 30 is installed with an angle adjustment mechanism. The angle adjustment mechanism is installed with the support seat 5 and controls the angle of the support seat 5 in the three axial directions of XYZ compared to the through hole 7. Each No. 1 linear reciprocating hydraulic cylinder 29 is respectively connected to the oil circuit of the external hydraulic system.

[0029] Furthermore, the linear reciprocating hydraulic cylinder 29 can be controlled to extend and retract through an external hydraulic system, thereby enabling the lifting seat 30 and the support seat 5 to move up and down, and then changing the clamping height position of the contact roller relative to the drill rod, so that the drill rod can be clamped and limited at a position closer to the drill hole at the initial stage of drilling and after the drill bit has completely entered the hole, thereby improving the guiding effect on the drill rod.

[0030] The angle adjustment mechanism includes a No. 2 linear reciprocating hydraulic cylinder 32, a spherical head 33, a top seat 34, a spherical shell 35, a spherical protrusion 36, and a limiting groove 37. The lifting seat 30 is fixed with three vertical No. 2 linear reciprocating hydraulic cylinders 32 at equal angles on the circumference. The top of the piston rod of each No. 2 linear reciprocating hydraulic cylinder 32 is respectively fixed with a spherical head 33. Each of the spherical heads 33 is spherically connected to the top seat 34. The top of each top seat 34 is smooth, and the top can respectively fit in contact with the bottom of the support seat 5. The middle part of the lifting seat 30 is fixed with an incomplete spherical shell that runs through it from top to bottom. Body 35, an incomplete spherical protrusion 36 is fixed on the outer wall of the bottom of the support seat 5, the spherical shell 35 is spherically connected to the spherical protrusion 36, and three limiting grooves 37 are fixed at equal angles on the circumference of the bottom end of the support seat 5. Each of the top seats 34 is respectively inserted into the limiting groove 37 with a gap, and each of the No. 2 linear reciprocating hydraulic cylinders 32 is respectively connected to the external hydraulic system oil circuit. The drilling direction guiding device of the drilling rig for mining also includes a cleaning mechanism. The No. 1 linear reciprocating hydraulic cylinder 29 is a double-acting hydraulic cylinder, and the No. 2 linear reciprocating hydraulic cylinder 32 is a single-acting hydraulic cylinder.

[0031] By controlling the No. 2 linear reciprocating hydraulic cylinder 32 to extend to different degrees through the hydraulic system, the top seat 34 can be used to touch the support seat 5 to different degrees, and then the angle of the support seat 5 relative to the base 1 in the three axial directions of XYZ can be adjusted under the rotation connection between the spherical shell 35 and the spherical protrusion 36, so as to better adapt to the angle of the drill rod relative to the base 1, making the drilling operation more convenient and quick.

[0032] The cleaning mechanism includes a No. 2 support 38, a speed regulating motor 39, a guide plate 40, a sliding cylinder 41, a No. 2 tension spring 42, a permanent magnet 43, a brush 44, and an electromagnet 45. A plurality of No. 2 supports 38 are fixed at equal angles on the top circumference of the support seat 5. Each of the No. 2 supports 38 is respectively fixed with a horizontal speed regulating motor 39. The rotating shaft of each speed regulating motor 39 is respectively arranged radially in a centripetal direction relative to the through hole 7. The rotating shaft of each speed regulating motor 39 is respectively fixed with a guide plate 40 extending in the radial direction. Each of the guide plates 40 is respectively connected to a sliding cylinder 41 in an axially sliding manner relative to the rotating shaft of the speed regulating motor 39. Each of the sliding cylinders 41 A No. 2 tension spring 42 is fixed between the guide plate 40, and a permanent magnet 43 is fixed to the axial end of each sliding cylinder 41 close to the No. 2 support 38, and a disc-shaped brush 44 is fixed to the axial end away from the No. 2 support 38. An electromagnet 45 is fixed to each No. 2 support 38, and each electromagnet 45 corresponds horizontally to each permanent magnet 43. When current in different directions is passed through the electromagnet 45, it can magnetically attract and magnetically repel the permanent magnet 43, so that the sliding cylinder 41 slides back and forth along the guide plate 40. The speed control motor 39 and the electromagnet 45 are electrically connected to the electronic control system 19 respectively.

[0033] Furthermore, before drilling begins, the electromagnet 45 is not energized. At this time, the sliding cylinder 41 can be moved close to the No. 2 support 38 under the elastic tension of the No. 2 tension spring 42, so that the brushes 44 are separated from each other, and then the drill rod passes through the through hole 7; after the drill rod passes through the through hole 7, the electromagnet 45 is energized, so that the electromagnet 45 and the permanent magnet 43 are magnetically repelled, so that the brush 44 and the drill rod are fitted together, and then the speed regulating motor 39 is controlled to rotate, so that the brush 44 is rotated, thereby cleaning the outer surface of the drill rod. Since the cleaning position is above the contact roller, the drill rod will be cleaned first when drilling downward, thereby reducing the interference with the contact between the contact roller and the drill rod, making the limit of the drill rod more stable.

[0034] The cleaning mechanism includes a No. 1 electric push rod 46, a support rod 47, a No. 3 support 48, a pulley 49, a steel belt 50, and a shield 51. Three horizontal No. 1 electric push rods 46 are fixed at equal angles on the top circumference of the base 1, and three vertical support rods 47 are fixed at equal angles on the top circumference. Each of the support rods 47 and each No. 1 electric push rod 46 is radially horizontally corresponding to the perforation 2. Each of the No. 1 electric push rods 46 is radially concentrically arranged compared to the perforation 2, and the ends of the push rods away from the perforation 2 are respectively fixed with vertical No. 3 supports of different heights. 48. Each of the No. 3 supports 48 is rotatably connected to a pulley 49. The heights of the pulleys 49 are arranged differently from top to bottom, and are respectively rolled and rubbed with a steel belt 50. A protective cover 51 that half-wraps the pulley 49 is fixed to the portion of each of the No. 3 supports 48 away from the perforation 2. Each of the steel belts 50 is gap-inserted into the protective cover 51. The lower portion of the outer wall of each of the steel belts 50 is a pointed inclined chamfered structure, and can be gap-inserted with the support rod 47. The portion of each of the steel belts 50 close to the perforation 2 can be gap-inserted with the drill rod of the drilling rig.

[0035] Furthermore, before drilling, first control the No. 1 electric push rod 46 to retract, so that the length of the steel belt 50 near the perforation 2 can be increased, and then the same steel belt 50 is manually inserted into each support rod 47 with a gap, and then the No. 1 electric push rod 46 is controlled to gradually extend, so that the steel belt 50 gradually tends to be straightened. At this time, the steel belt 50 is supported and limited by the support rod 47, which can avoid further contraction and contact with the drill rod that is about to pass through. Then the drill rod and the drill bit are passed through each steel belt 50 for normal drilling. After drilling is completed, first control the No. 1 electric push rod 46 is retracted to increase the length of the steel belt 50 near the perforation 2, and then it is manually released from the gap insertion with the two support rods 47 in other directions. At this time, the steel belt 50 is only gap-inserted with the support rod 47 directly below it, and then the No. 1 electric push rod 46 is controlled to extend to make the steel belt 50 contact with the surface of the drill rod. Through this overlapping encirclement in three horizontal directions, full coverage of the circumferential angle of the drill rod can be achieved. At this time, when the drill rod is lifted, the sludge and other substances that are not easy to fall off attached to the surface of the drill rod can be scraped and cleaned, which is convenient for next use.

[0036] The cleaning mechanism includes a No. 2 electric push rod 52, a lifting frame 53, a mesh cover 54, and an elastic member. Three vertical No. 2 electric push rods 52 are fixed at equal angles on the top circumference of the base 1. The top of each No. 2 electric push rod 52 is fixed to the annular lifting frame 53. The lifting frame 53 is fixed with a mesh cover 54. The mesh cover 54 is made of soft and foldable elastic material, and the upper part has a tendency to gather toward the virtual axis position of the perforation 2. The upper part of the mesh cover 54 and the bottom end of the support seat 5 are fixed with an elastic member. The mesh cover 54 always remains stretched upward under the pull of the elastic member.

[0037] Furthermore, by utilizing the elasticity of the elastic member and the mesh cover 54 itself, the opening at the top of the mesh cover 54 can be manually enlarged, thereby facilitating the passage of the drill rod and the drill bit. During the drilling process, the elasticity of the mesh cover 54 can be utilized to tighten the mesh cover 54 and bring it closer to the drill rod, while the elastic member can be utilized to make the mesh cover 54 in an upwardly stretched state, thereby being able to intercept the ejected debris or gushing mud and sand during the drilling process to a certain extent, making it safer and reducing the amount of diffusion along the drill rod, thereby reducing contamination to the drill rod and reducing the adverse effects on the drill rod guidance. By controlling the extension and retraction of the No. 2 electric push rod 52, the height position of the mesh cover 54 relative to the perforation 2 can be adjusted, so that different adjustments can be made according to needs. For example, when the steel belt 50 needs to be manually operated, lifting the lifting frame 53 can free up more space and be more convenient for operation.

[0038] The elastic member includes a lower elastic pull belt 56, a support block 57, a ball 58, and an upper elastic pull belt 59. The lower elastic pull belt 56 is in a closed ring shape and passes through each support block 57 horizontally. The end of each support block 57 close to the virtual axis of the through hole 7 is rotatably connected to a plurality of ball 58, and the end away from the virtual axis of the through hole 7 is fixed to the upper part of the mesh cover 54. The ball 58 of the same support block 57 is arranged horizontally and arranged correspondingly up and down. The top of each support block 57 and the bottom of the support seat 5 are jointly fixed with an upper elastic pull belt 59. Under the pull of the lower elastic pull belt 56, each support block 57 has a tendency to approach each other, so that the ball 58 can roll and rub against the drill rod of the drilling rig. Under the pull of the upper elastic pull belt 59, each support block 57 has a tendency to move upward, so that the mesh cover 54 stretches upward.

[0039] Furthermore, by pulling the support block 57 with the lower elastic pull belt 56, the ball 58 can be subjected to rolling friction with the surface of the drill rod, thereby reducing the wear on the mesh cover 54 and extending its service life.

[0040] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, based on the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
