A mine drilling rig apparatus

Abstract

The application belongs to the technical field of mining drilling machines, and specifically discloses a mine drilling machine device, which comprises a mobile main body, a drilling machine slidingly arranged on the mobile main body, a drill rod connected to the drilling machine, a limiting seat slidingly arranged on the mobile main body and used for limiting the drill rod, and a reciprocating dismounting mechanism slidingly arranged between the drilling machine and the limiting seat and comprising two groups of return letting-go clamping assemblies which are synchronously slidingly arranged along the width direction of the mobile main body. The reciprocating dismounting mechanism is arranged between the drilling machine and the limiting seat, so that the two drill rods can be removed in one reciprocating interval, which is very convenient and fast. Compared with a traditional drill rod dismounting mechanism through a mechanical arm, the reciprocating dismounting mechanism can more quickly and stably remove the drill rods, and the whole action process does not occupy space outside the mobile main body, which is very friendly to narrow tunnel areas such as underground areas.

Description

Technical Field

[0001] This application relates to the field of mining drilling rig technology, and more particularly to a drilling rig equipment for mines. Background Technology

[0002] Mining drilling equipment is developing towards automation and intelligence, with more and more auxiliary devices being installed on drilling rigs. For drilling rigs used for large-diameter boreholes, the large diameter and weight of the drill rods make the installation and disassembly of drilling equipment extremely inconvenient. In most cases, external auxiliary robotic arms are needed for disassembly and installation. However, given the size of underground drilling sites in coal mines and the installation requirements of robotic arms, the path planning of the robotic arms is relatively complex, and the probability of collisions with the robotic arms in confined spaces is significantly increased, greatly increasing the later maintenance costs.

[0003] Currently, some energy-saving drilling rigs are often equipped with wheel-type disassembly structures, which disassemble drill rods by means of rotation and clamping. For example, patent document CN221646839U discloses an automatic anchor bolt drilling rig for coal mines, in which the anchor bolt is first removed through a rod-changing mechanism and then transferred to the anchor bolt chamber assembly. The anchor bolt chamber assembly then rotates to remove the anchor bolt. The current drill rod disassembly and assembly process is similar to that of the aforementioned anchor bolt disassembly and assembly. Although it improves the portability of disassembling drill rods to a certain extent, it still has certain drawbacks. For example, such mechanisms require multiple hydraulic components to realize the clamping and transfer actions of a robotic arm, such as the swing cylinder and clamping cylinder in the aforementioned document. This results in a certain spatial movement trajectory for the mechanism. When the entire device is located in a mine tunnel, the movement trajectory of such mechanisms is very likely to interfere with the narrow tunnel space, or the movement trajectory needs to be reset, which seriously affects the normal progress of drilling work.

[0049] The present application will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present application, and therefore only show the components relevant to the present application.

[0050] like Figure 1-13 As shown, a mining drilling rig includes:

[0051] Mobile Main Body 1; Mobile Main Body 1 provides a mobile foundation and installation carrier for the entire auxiliary mechanism. It can be tracked to adapt to complex terrain in the mine and facilitate the transfer of equipment between different mine drilling sites.

[0052] The drilling rig 2 is slidably mounted on the moving body 1; a drill rod 7 is connected to the drilling rig 2; the drilling rig 2 is slidably mounted on the moving body 1, and can be docked or separated from the drill rod 7 by sliding. When drilling is performed, the drilling rig 2 slides to the working position and connects with the drill rod 7; when disassembling the drill rod 7, the drilling rig 2 can be separated from the drill rod 7 by sliding in the opposite direction, which simplifies the docking operation.

[0053] Drilling rig 2 can preferably be an energy-saving hydraulic drilling rig.

[0054] The limiting seat 5 is slidably mounted on the moving body 1 to limit the drill rod 7. The limiting seat 5 is also slidably mounted on the moving body 1, and its position can be adjusted according to the length of the drill rod 7. It achieves the limiting by cooperating with the end of the drill rod 7 to prevent the drill rod 7 from moving axially or rotating radially during disassembly and assembly, thus ensuring operational stability.

[0055] The reciprocating disassembly and assembly mechanism 4 is slidably arranged between the drilling rig 2 and the limit seat 5, including two sets of return clearance clamping components 40, which are synchronously slidably arranged along the width direction of the moving body 1.

[0056] The reciprocating disassembly and assembly mechanism 4 slides between the drilling rig 2 and the limiting seat 5. It includes two sets of return clearance clamping components 40 that slide synchronously along the width direction of the moving body 1. The synchronous sliding design ensures that the two sets of components move in unison. That is, when one set is about to remove the drill rod 7, the other set has already transported the previously removed drill rod 7 to another transfer position, thereby improving the efficiency of disassembling the drill rod 7 and further improving the working efficiency of a single drilling rig 2. This reduces the need to deploy multiple drilling rigs 2 and saves more energy.

[0057] Compared to the prior art which relies on an external robotic arm, this application sets a reciprocating disassembly and assembly mechanism 4 between the drilling rig 2 and the limiting seat 5. This allows for the removal of two drill rods 7 within a single reciprocating interval, which is very convenient and quick. Compared to the traditional drill rod 7 disassembly mechanism that uses a robotic arm, the reciprocating disassembly and assembly mechanism 4 of this application can remove the drill rods 7 faster and more stably. Furthermore, the entire process does not occupy any space other than the moving body 1, making it very suitable for narrow tunnel areas such as underground wells.

[0058] In some further embodiments, two sets of rotary transfer mechanisms 3 are also included, which are rotatably arranged and located on both sides of the width direction of the moving body 1. The rotary transfer mechanisms 3 are synchronously slidably arranged with the reciprocating disassembly and assembly mechanism 4. The rotary transfer mechanism 3 includes a rotating shaft 36 and a plurality of hinge frames 30 arranged on the rotating shaft 36. The hinge frames 30 are configured to transport the drill rod 7 in the return clearance clamping assembly 40 to one side of the width direction of the moving body 1.

[0059] Two sets of rotary transfer mechanisms 3 are rotatably arranged on both sides of the width of the moving body 1, and their symmetrical distribution ensures that the drill rod 7 can be transferred to both sides, thereby improving space utilization.

[0060] The rotating shaft 36 of the rotary transfer mechanism 3 is driven to rotate by a drive motor. Multiple hinged frames 30 are radially distributed along the rotating shaft 36, forming a circular conveying track as the rotating shaft 36 rotates.

[0061] When the reciprocating assembly / disassembly mechanism 4 delivers the drill rod 7 to the transfer position, the articulated frame 30 rotates to the bottom or side of the drill rod 7, supporting it with its own structure. As the rotating shaft 36 continues to rotate, it transports the drill rod 7 to one side of the moving body 1 in the width direction. This design achieves automated transfer of the drill rod 7, replacing manual handling, reducing labor intensity and safety hazards. Simultaneously, transferring the drill rod 7 to the side of the main body frees up top working space, facilitating subsequent stacking or retrieval of the drill rod 7 and improving operational continuity.

[0062] The rotary transfer mechanism 3 can move synchronously along the axis of the moving body 1 with the reciprocating disassembly and assembly mechanism 4, which can be achieved by connecting the cantilever 104 to each other.

[0063] In some further embodiments, the return clearance clamping assembly 40 includes two sets of grippers 41 and two sets of racks 402. The two sets of grippers 41 are spaced apart along the width direction of the moving body 1, and the two sets of racks 402 are spaced apart along the length direction of the moving body 1.

[0064] One end of one set of grippers 41 is connected to one end of one set of racks 402, and the other end is slidably connected to one end of another set of racks 402 along the width direction of the moving body 1.

[0065] One end of another set of grippers 41 is slidably connected to the other end of one set of racks 402 along the width direction of the moving body 1, and the other end is connected to the other end of another set of racks 402.

[0066] A power gear 403 is provided between the two sets of racks 402, which meshes with both sets of racks 402.

[0067] The jaw 41 is fixedly connected to the gear by bolts, while the sliding between the two is achieved by the sliding groove 420 and the sliding protrusion. That is, the sliding groove 420 is provided on the rack 402, and the sliding protrusion is provided on the jaw 41.

[0068] When the power gear 403 rotates, the two racks 402 move in the same direction or in opposite directions, causing the two grippers 41 to move closer to each other and further away from each other, thereby clamping and releasing the drill rod 7.

[0069] The power gear 403 is driven to rotate by a servo motor.

[0070] In some further embodiments, the jaw 41 includes a mounting portion 412 for connection with the rack 402 and a clamping portion 411 for clamping the drill rod 7; the clamping portion 411 is hinged to the top of the mounting portion 412; the clamping portion 411 of the two jaws 41 that are close to each other in the two sets of return clearance clamping assemblies 40 is configured to be able to rotate away from its corresponding mounting portion 412; a return torsion spring 401 is provided between the clamping portion 411 and the mounting portion 412, and the return torsion spring 401 is configured to be able to reset the clamping portion 411 that has rotated relative to the mounting portion 412.

[0071] The mounting portion 412 of the jaw 41 is used to connect with the rack 402, providing a mounting base for the clamping portion 411; the clamping portion 411 is hinged to the top of the mounting portion 412 and can rotate about the hinge axis. The clamping portions 411 of the two jaws 41 that are close to each other in the two sets of return clearance clamping assemblies 40 can rotate away from their respective mounting portions 412 (i.e., in a direction away from each other) when the two sets of assemblies are close to each other, so that the entire return clearance clamping assembly 40 is positioned exactly below the drill pipe 7 by the hinge bending of the clamping portion 411. It can be known that the hinge bending of the clamping portion 411 is precisely to avoid the drill pipe 7 to be disassembled.

[0072] The return torsion spring 401 between the clamping part 411 and the mounting part 412 can rotate the clamping part 411 back to its initial position through its elastic force after the clamping part 411 completes the yielding action, ensuring the accuracy of the next clamping action. This design enables the gripper 41 to achieve automatic reset while having a yielding function, without the need for an additional drive device, simplifying the structure while improving the automation level and working efficiency of the mechanism.

[0073] Specifically, the rotation between the clamping part 411 and the mounting part 412 can be achieved by a common shaft structure, and the return torsion spring 401 can be set on the shaft structure, with one end of the return torsion spring 401 connected to the clamping part 411 and the other end connected to the mounting part 412.

[0074] It should be noted that, due to the inclined limiting structure at the connection between the clamping part 411 and the mounting part 412, the clamping part 411 can only be hinged and bent in one direction to ensure the clamping strength of the drill rod 7.

[0075] In some further embodiments, the moving body 1 is provided with an axial sliding guide rail along the length direction of the moving body 1, and the axial sliding guide rail is provided with a first sliding seat 100 for carrying the drilling rig 2 and a second sliding seat 102 for carrying the reciprocating disassembly and assembly mechanism 4.

[0076] The first sliding seat 100 is provided with a first telescopic rod 6. One end of the first telescopic rod 6 away from the first sliding seat 100 passes through the second sliding seat 102, and a limiting handle 60 is provided on the end that passes through. The moving body 1 is also provided with a limiting plate 103 for limiting the movement of the second sliding seat 102 toward the first sliding seat 100.

[0077] The axial sliding guide rail on the moving body 1 extends along the length direction, providing guidance for the first sliding seat 100 and the second sliding seat 102, ensuring that they slide smoothly and accurately. The first sliding seat 100 supports the drilling rig 2, and the second sliding seat 102 supports the reciprocating disassembly and assembly mechanism 4, allowing the two to be independently adjusted along the guide rail to adapt to the disassembly and assembly needs of drill rods 7 of different lengths.

[0078] After a drill rod 7 is removed, the first sliding seat 100 moves closer to the limiting seat 5. During this process, the first sliding seat 100 will abut against the second sliding seat 102 and move synchronously. When the drilling machine 2 successfully attaches the next drill rod 7 to be removed and rotates to lock it, the first sliding seat 100 will move away from the limiting seat 5. When it moves to a certain distance, the extension and retraction of the first telescopic rod 6 reaches its maximum. Thus, under the action of the limiting handle 60, the second sliding seat 102 will be pulled back to its initial position. In order to prevent the second sliding seat 102 from getting too close to the first sliding seat 100 under the action of inertia, a limiting plate 103 is specially set on the moving body 1 to limit the movement of the second sliding seat 102.

[0079] In addition, a clearance hole is provided on the limiting seat 5 to allow clearance for one end of the first telescopic rod 6 that protrudes outside the second sliding seat 102, so as to ensure that the second sliding seat 102 fits with the limiting seat 5.

[0080] The synchronous movement of the two sets of return clearance clamping components 40 relative to the second sliding seat 102 is achieved through a lead screw structure. That is, the bottom of the two sets of return components can be equipped with a nut slider that cooperates with the lead screw, and the rotation of the lead screw is achieved by a motor.

[0081] In some further embodiments, multiple hinge frames 30 are arranged circumferentially along the pivot 36 to form a set of hinge frames 30. There are four sets of hinge frames 30, and the four sets of hinge frames 30 are located on both sides of the reciprocating disassembly and assembly mechanism 4 in the length direction of the moving body 1.

[0082] The hinge frame 30 is provided with a bending section.

[0083] Multiple articulated frames 30 are evenly arranged around the circumference of the rotating shaft 36 to form a set of articulated frames 30. Two of the four sets of articulated frames 30 are located on one side of the reciprocating disassembly and assembly mechanism 4, and the other two are located on the other side, so as to jointly complete the lifting of the drill rod 7.

[0084] The bent portion on the articulated frame 30 is adapted to the outer contour of the drill rod 7, and can wrap around part of the outer periphery of the drill rod 7 during transportation, enhancing the constraint on the drill rod 7. This arrangement allows the rotating shaft 36 to complete one receiving or transporting of the drill rod 7 every time it rotates a certain angle (the specific angle depends on the number of articulated frames 30 in the articulated frame group 30), thereby improving transfer efficiency; the design of the bent portion can prevent the drill rod 7 from slipping during transportation, ensuring transfer safety.

[0085] When the drill rod 7 located in the bend rotates with the rotary transfer mechanism 3, when the drill rod 7 rotates more than 90° from the time it is lifted, the drill rod 7 will slide between two adjacent hinge frames 30 in the circumferential direction, and finally slide directly from the back of a hinge frame 30 downstream of the hinge frame 30 that actually lifts the drill rod 7 into a specific drill rod 7 collection rack.

[0086] In some further embodiments, the hinge frame 30 includes a connecting arm 301 and a hinge arm 302 that are hinged to each other. The connecting arm 301 is hinged to the rotating shaft 36, and a bend is formed at the connection between the connecting arm 301 and the hinge arm 302.

[0087] In the two sets of hinged frames 30 located on one side of the reciprocating disassembly and assembly mechanism 4, the connecting arm 301 and the hinged arm 302 are hinged together with an adjustment shaft 31, and the end of the hinged arm 302 away from the bending part is hinged together with a limiting shaft 32.

[0088] The rotating shaft 36 is provided with a second telescopic rod 34 corresponding to two sets of hinge frames 30 that are far apart from each other. The end of the second telescopic rod 34 away from the rotating shaft 36 is hinged to a limiting shaft 32; the two telescopic sections on the second telescopic rod 34 are elastically connected.

[0089] The connecting arm 301 of the hinge frame 30 is hinged to the rotating shaft 36, and the hinge arm 302 is hinged to the connecting arm 301. The connection between the two forms a bend, which allows the hinge frame 30 to adjust its overall shape by rotating the two arms relative to each other, thereby satisfying the installation of the drill rod 7.

[0090] In the two sets of hinge frames 30 located on one side of the reciprocating disassembly and assembly mechanism 4, the adjusting shaft 31 connects the hinge joints of all connecting arms 301 and hinge arms 302 in the same set, and the limiting shaft 32 connects the ends of all hinge arms 302 in the same set away from the connecting arms 301, so as to ensure that the hinge frames 30 in the same set move synchronously.

[0091] The end of the second telescopic rod 34 on the rotating shaft 36 away from the rotating shaft 36 (its two telescopic sections are connected by elastic components such as spring 33) is hinged to the limiting shaft 32.

[0092] The accompanying drawings of this application show the posture of the articulated frame 30 when the drill rod 7 is disassembled. When the drill rod 7 is installed, the posture of the articulated frame 30 will change to some extent.

[0093] First, pull the adjusting shaft 31 along the bisector of the angle formed by the connecting arm 301 and the hinge arm 302. When pulled forcefully, the second telescopic rod 34 extends and the spring 33 is stretched. At this time, the angle between the connecting arm 301 and the hinge arm 302 gradually decreases and eventually becomes a flat angle. Then, continue to pull the adjusting shaft 31. Since the spring 33 has the greatest extension when in the flat angle state, the spring 33 will return to its original state after the flat angle state. At this time, the bent part in the hinge frame 30 will "reverse", so that the rotary transfer mechanism can reverse to install the drill rod 7 on the drilling machine 2.

[0094] It should be noted that during reversal, the drill rod 7 also slides down the back side of one of the hinge frames 30 downstream of the hinge frame 30 between the two jaws 41. In reality, the drill rod 7 does not slide exactly above the middle of the two jaws 41, but rather slides onto a jaw 41 that is relatively close to the middle of the entire moving body 1 and will come into contact with it. For this reason, a support rod 404 is specially provided to extend upward at the top center of the power gear 403 to support the drill rod 7 to be clamped.

[0095] As the hinge frame 30 rotates, the drill rod 7 will gradually detach from the hinge frame 30 and be supported on the top of the support rod 404.

[0096] In addition, it should be clarified that in the embodiment with simultaneous disassembly and assembly functions, only the two middle sets of the four sets of articulated frames 30 are used to support the drill rod 7 during the disassembly and assembly process. The other two sets do not participate in the transfer of the drill rod 7, but are only used to assist in changing the posture of the articulated frames 30.

[0097] The end of the second telescopic rod 34 near the rotating shaft 36 is fixedly connected to the rotating shaft 36.

[0098] In some further embodiments, a toggle frame 35 is provided on the rotating shaft 36 corresponding to two sets of hinge frames 30 that are far apart from each other. The toggle frame 35 includes a rotating ring 350 and a rotating disk 351. The rotating ring 350 is connected to all the first adjusting shafts 31 in the hinge group, and the rotating disk 351 is rotatably mounted on the rotating shaft 36.

[0099] Rotating disk 351 is connected to rotating disk 352 by connecting rod 352.

[0100] The toggle bracket 35 is mainly used to facilitate the rotation of multiple adjusting shafts 31, so as to facilitate the shape change of the hinge bracket 30.

[0101] The connecting rod 352 has an L-shaped structure.

[0102] In some further embodiments, the limiting seat 5 is provided with a limiting sleeve 50 and a limiting rod 51, the limiting sleeve 50 is provided with a limiting hole that penetrates radially, and the telescopic section of the limiting rod 51 is located in the limiting hole.

[0103] The limiting sleeve 50 on the limiting seat 5 is used to fit the drill rod 7. Its inner diameter is adapted to the outer diameter of the drill rod 7, and is slightly larger in actual practice to allow the drill rod 7 to rotate.

[0104] The limiting hole on the limiting sleeve 50 extends radially, and the telescopic section of the limiting rod 51 (which can be a hydraulic rod) passes through the limiting hole. When the drill rod 7 is inserted into the limiting sleeve 50, the telescopic section extends and presses against the outer circumference of the drill rod 7, fixing the drill rod 7 inside the limiting sleeve 50 to prevent it from moving axially or rotating radially. It should be noted that directly pressing the drill rod 7 is only used during the disassembly and assembly of the drill rod 7. When the drilling machine 2 drives the drill rod 7 to work, the drill rod 7 is not directly locked by the limiting rod 51.

[0105] The end of the telescopic section can be an arc surface that fits the outer peripheral wall of the drill pipe 7.

[0106] In some further embodiments, the mobile body 1 includes a vehicle body 11 and a working platform 10. The end of the working platform 10 away from the drilling is hinged to the vehicle body 11. The vehicle body 11 of the mobile body 1 provides the equipment with mobility. The end of the working platform 10 away from the drilling is hinged to the vehicle body 11 and can be driven by a hydraulic device to rotate around the hinge axis, thereby adjusting the tilt angle of the working platform 10 to adapt to different drilling heights or drilling site terrain.

[0107] The axial sliding guide rail is set on the working platform 10. The axial sliding guide rail is set on the working platform 10 to ensure that the drilling rig 2, reciprocating disassembly and assembly mechanism 4 and other components can still slide along the preset trajectory after the angle of the working platform 10 is adjusted.

[0108] In some further embodiments, the bottom of the movable body 1 is provided with a support leg 110, and the top of the movable body 1 is provided with a hydraulic push rod 111.

[0109] The outriggers 110 at the bottom of the mobile main body 1 extend and support the ground during operation, increasing the contact area with the ground and lowering the center of gravity of the equipment; the hydraulic jacks 111 at the top extend and press against the top of the mine, forming a fixed structure with the outriggers 110. This design enables the equipment to remain stable in complex terrain underground, preventing displacement or tipping due to vibration during operation and ensuring operational safety.
