Description

Technical Field

[0001] This invention relates to the field of drilling rig machinery technology, and more specifically to a drilling device. Background Technology

[0002] Directional drilling rigs play an irreplaceable role in the field of coal mining, as they can drill along a pre-set trajectory to precisely reach the target layer or location.

[0003] In a single operation, directional drilling rigs require connecting drill rods one by one before drilling. Manual loading and unloading of drill rods is labor-intensive and poses safety hazards. Mainstream automatic drill rod systems typically have a drill rod storage box and a robotic arm for grabbing drill rods mounted on the side of the machine. For example, Chinese patent CN111852332B discloses an automatic drill rod adding rig with a built-in drill rod box, specifically disclosing the drill rod box, lifting mechanism, and robotic arm assembly. This system is not only complex in structure but also occupies a large space, which is not conducive to narrow downhole working spaces. Furthermore, after replacing drill rods, the suspended portion of the drill rod is relatively long, and the lack of support makes it prone to bending, causing the drill rod to rotate eccentrically and potentially damaging the drill rod or related equipment.

[0004] Based on this, the present invention designs a drilling device to solve the above problems. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a drilling device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A drilling apparatus includes a frame and a drilling control mechanism mounted on the frame; A storage box for storing drill rods is fixedly installed at the rear end of the frame. A drill rod loading and unloading mechanism is installed at the lower end of the storage box. Multiple sets of the drill rod loading and unloading mechanism are evenly distributed along the length of the drill rod. The drill rod loading and unloading mechanism includes a translation component, a clamping support component, and a loading and unloading component. The translation component is installed on the frame. The moving end of the translation component is equipped with the clamping support component and the loading and unloading component. The loading and unloading component is used to control the flow of the drill rod between the storage box and the clamping support component. The clamping support component is used to clamp the drill rod to cooperate with the translation component to control the loading and unloading of the drill rod and support the suspended part of the drill rod. The right end of the frame is also equipped with a high-efficiency cleaning mechanism, which is used to clean impurities on the surface of the drill rod when it is being recycled.

[0007] Furthermore, the clamping support assembly includes a fixed support assembly and a flipping clamping assembly, both of which are mounted on a translation plate, and the two work together to clamp and fix the drill rod.

[0008] Furthermore, the fixed support assembly includes a stand and fixed clamping wheels. The stand is fixedly connected to the moving end of the translation assembly. The stand is rotatably mounted with fixed clamping wheels, and multiple fixed clamping wheels are arranged on the same arc. The flipping clamping assembly includes a flipping shaft, a flipping frame, movable clamping wheels, and a flipping drive assembly. The flipping shaft is hinged to the upright frame, and the flipping frame is fixedly connected to the flipping shaft. Movable clamping wheels are rotatably mounted on the flipping frame, and multiple movable clamping wheels are arranged on the same arc. The flipping drive assembly is mounted on the translation plate, and the output end of the flipping drive assembly is connected to the flipping shaft.

[0009] Furthermore, the storage box includes a support base, partitions, and end telescopic limiting components. Two support bases are fixedly installed on the left and right sides of the frame, and the two support bases are connected and fixed together by steel profiles. Multiple partitions are fixedly installed on the support bases along the length of the support bases, and the partitions divide the front of the support bases into multiple independent storage compartments for vertically storing drill rods. End telescopic limiting components are installed on both sides of each storage compartment, and the end telescopic limiting components extend into the end of the drill rod to limit and release the drill rod at the bottom of the storage compartment.

[0010] Furthermore, the loading and unloading assembly includes an auxiliary support assembly and a lifting loading and unloading assembly. The lifting loading and unloading assembly is used to control the lifting and lowering movement of the drill rod on the clamping support assembly, and the auxiliary support assembly is used to provide transitional support for the drill rod before the clamping support assembly clamps the drill rod.

[0011] Furthermore, the auxiliary support assembly includes a support block, a slide rod, a roller, and a control ramp. The lower end of the slide rod is slidably connected to the moving end of the translation assembly, and the upper end of the slide rod is fixedly connected to the support block. The lower end of the support block is rotatably mounted with a roller. The front end of the translation assembly is fixedly mounted with a control ramp that is slidably connected to the roller.

[0012] Furthermore, the high-efficiency cleaning mechanism includes a first cleaning mechanism, a second cleaning mechanism, and a water collection tank. The water collection tank is fixedly installed at the right end of the frame and located on the right side of the clamp. The first cleaning mechanism and the second cleaning mechanism are installed on the water collection tank, with the second cleaning mechanism located between the first cleaning mechanism and the clamp. The first cleaning mechanism is used to perform preliminary cleaning of the drill rod and soften its surface dirt. The second cleaning mechanism is used to perform deep cleaning of the drill rod and remove the dirt from its surface. The water collection tank is used to collect wastewater during the cleaning of the drill rod.

[0013] Furthermore, the first cleaning mechanism includes a first bracket, a surface wiping component, and a centering drive component. The first bracket is fixedly installed on the upper end of the water collection tank, the centering drive component is installed on the upper end of the first bracket, and the surface wiping component is installed on the centering drive component.

[0014] Furthermore, the surface wiping assembly includes a liquid inlet pipe, a mounting block, and a cleaning block. The mounting block is fixedly installed at the end of the liquid inlet pipe, and a cleaning block for wiping dirt off the drill pipe surface is fixedly installed on the mounting block. The liquid inlet pipe stores cleaning fluid, and the mounting block has a small gap communicating with the liquid inlet pipe.

[0015] Furthermore, the second cleaning mechanism includes a second bracket, a rotating drum, a brush tube, a nozzle, and a second rotary drive assembly. The second bracket is fixedly connected to the water collection tank. A rotating drum is rotatably mounted on the upper end of the second bracket. A brush tube is installed inside the rotating drum, and the inner wall of the brush tube is evenly covered with bristles. A second rotary drive assembly is installed between the rotating drum and the second bracket. Multiple nozzles are also fixedly mounted in a circumferential array on the upper end of the second bracket. The nozzles are used to spray clean water onto the drill rod.

[0016] Compared with the prior art, the beneficial effects of this invention are as follows: 1. The storage box and the frame are integrated into a single structure. The independent storage compartments allow the drill rods to be arranged in a matrix-like dense arrangement within the storage box, which significantly increases the storage box capacity and reduces the number of times drill rods need to be added to the storage box during a single drilling operation. The matrix arrangement of the drill rods also facilitates the recording of the number and position information of the drill rods in the drill rod box, which is beneficial for controlling the lateral position of the support slide rail. This application controls the vertical movement of the drill rods separately by gravity, the lifting and unloading components, and the side push cylinder, and controls the lateral movement of the drill rods by the translation component. This allows the drill rod loading and unloading mechanism to achieve the transfer action of the drill rods even when the installation space is limited. At the same time, it can effectively prevent the position of the drill rods from shifting during the clamping process, so as to achieve a precise conveying effect of the drill rods. Meanwhile, during the drill rod pushing operation, the drill rods are supported by the cooperation of fixed clamping wheels and movable clamping wheels to prevent the drill rods from being too long and deformed. The overall structure of this invention is compact and simple, and easy to manufacture, assemble, and maintain.

[0017] 2. When the drill rod needs to be recycled, the centering drive component controls the cleaning blocks to fit tightly against the drill rod surface to achieve a wiping effect. Multiple cleaning blocks are staggered on the drill rod surface to achieve a thorough wiping effect without dead angles. At the same time, cleaning fluid continuously flows onto the drill rod to soften the dirt on the drill rod surface. Then the drill rod moves into the rotating drum, where the rotating drum continuously brushes the drill rod surface. Then, clean water is sprayed onto the drill rod surface through the nozzle to achieve an all-round, thorough cleaning effect. Finally, the drill rod surface is dried by the dryer to prevent the drill rod from rusting. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0023] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-2 A drilling apparatus includes a frame 10 and a drilling control mechanism mounted on the frame 10; The drilling control mechanism includes a clamp 11, a power head 12, and a linear slide 13. The linear slide 13 is fixedly installed on the upper end of the frame 10. The linear slide 13 can be a hydraulically driven slide, a gear and rack slide, etc. The power head 12 is fixedly installed on the moving end of the linear slide 13. The power head 12 is used to control the rotation of the drill rod and the clamping of the drill rod. The power head 12 and the linear slide 13 work together to realize the feeding and pushing of the drill rod. The clamp 11 is fixedly installed on the right end of the frame 10. The clamp 11 is a hydraulic cylinder clamping double clamp. The front half of the clamp 11 is used to clamp the drill rod in the hole, and the rear half of the clamp 11 works with the power head 12 to connect and disconnect the drill rod.

[0024] The rear end of the frame 10 is fixedly equipped with a storage box 2 for storing drill rods. The lower end of the storage box 2 is equipped with a drill rod loading and unloading mechanism 3. Multiple sets of the drill rod loading and unloading mechanism 3 are evenly distributed along the length of the drill rod. The drill rod loading and unloading mechanism 3 includes a translation component 31, a clamping support component 32, and a loading and unloading component. The translation component 31 is mounted on the frame 10. The moving end of the translation component 31 is equipped with the clamping support component 32 and the loading and unloading component. The loading and unloading component is used to control the flow of the drill rod between the storage box 2 and the clamping support component 32. The clamping support component 32 is used to clamp the drill rod to cooperate with the translation component 31 to control the loading and unloading of the drill rod and to prevent the suspended part of the drill rod from being too long and deformed.

[0025] The right end of the frame 10 is also equipped with a high-efficiency cleaning mechanism 4, which is used to clean impurities on the surface of the drill rod when retrieving the drill rod.

[0026] In this invention, the linear slide 13 drives the power head 12 to move along the drill rod axis, and with the cooperation of the clamp 11, the drill rod can be automatically loaded and unloaded. The loading and unloading assembly controls the drill rod to flow between the storage box 2 and the clamping support assembly 32. Then, the translation assembly 31 drives the clamping support assembly 32 to move horizontally, so that the clamping support assembly 32 clamps and limits the drill rod and then moves the drill rod between the frame 10 and the storage box 2. At the same time, when the drill rod is pushed forward, the fixed clamping wheel 322 prevents the drill rod from being too long and deformed. When the power head 12 approaches, the translation assembly 31 controls the clamping support assembly 32 to automatically avoid it.

[0027] Please see Figures 3-8The translation component 31 includes a support slide rail 311, a translation plate 312, a translation rack 313, a translation gear 314, and a translation motor 315. The support slide rail 311 is fixedly connected to the frame 10, and the translation plate 312 is slidably connected to the support slide rail 311. The translation rack 313 is fixedly installed at the lower end of the translation plate 312. The translation motor 315 is fixedly connected to the frame 10, and the output end of the translation motor 315 is fixedly installed with a translation gear 314 that meshes with the translation rack 313. The translation motor 315 drives the translation gear 314 to rotate, and the translation rack 313 drives the translation plate 312 to slide along the support slide rail 311.

[0028] The clamping support assembly 32 includes a fixed support assembly and a flipping clamping assembly. Both the fixed support assembly and the flipping clamping assembly are mounted on the translation plate 312, and the two cooperate to clamp and fix the drill rod. The fixed support assembly includes a frame 321 and fixed clamping wheels 322. The frame 321 is fixedly connected to the translation plate 312. The fixed clamping wheels 322 are rotatably mounted on the frame 321. Multiple fixed clamping wheels 322 are provided and are on the same arc. The flipping clamping assembly includes a flipping shaft 323, a flipping frame 324, movable clamping wheels 325, and a flipping drive assembly. The flipping shaft 323 is hinged to the upright frame 321, and the flipping frame 324 is fixedly connected to the flipping shaft 323. Movable clamping wheels 325 are rotatably mounted on the flipping frame 324, and multiple movable clamping wheels 325 are arranged on the same arc. The flipping drive assembly is mounted on the translation plate 312, and the output end of the flipping drive assembly is connected to the flipping shaft 323. The flipping drive assembly includes a pull rod 326 and a flipping control push cylinder 327. One end of the pull rod 326 is fixedly connected to the flipping shaft 323. The housing of the flipping control push cylinder 327 is hinged to the translation plate 312. The output end of the flipping control push cylinder 327 is hinged to the end of the pull rod 326 away from the flipping shaft 323. By controlling the extension and retraction of the output end of the flip control cylinder 327, the pull rod 326 drives the flip frame 324 to rotate through the flip shaft 323, so that the movable clamping wheel 325 and the fixed clamping wheel 322 are on the same circumference, thereby achieving the clamping and limiting effect on the drill pipe.

[0029] The storage box 2 includes a support base 21, partitions 22, side push cylinders 23, and limiting blocks 24. Two support bases 21 are fixedly installed on the left and right sides of the frame 10, and the two support bases 21 are fixed together by steel profiles. Multiple partitions 22 are fixedly installed on the support bases 21 along the length of the support bases 21, and the partitions 22 divide the front of the support bases 21 into multiple independent storage compartments for vertically storing drill rods. Side push cylinders 23 are distributed on both sides of each storage compartment. The side push cylinders 23 are fixedly connected to the support bases 21, and the output end of the side push cylinders 23 is fixedly installed with a limiting block 24 for extending into the end of the drill rod. By controlling the extension and retraction of the output end of the side push cylinder 23, the limiting and release effect of the drill rod at the bottom of the storage compartment can be achieved. The loading and unloading assembly includes an auxiliary support assembly 33 and a lifting loading and unloading assembly 34. The lifting loading and unloading assembly 34 is used to control the lifting and lowering movement of the drill rod on the clamping support assembly 32. The auxiliary support assembly 33 is used to provide transitional support for the drill rod before the clamping support assembly 32 clamps the drill rod.

[0030] The auxiliary support assembly 33 includes a support block 331, a slide rod 332, a roller 333, and a control ramp 334. The lower end of the slide rod 332 is slidably connected to the translation plate 312, and the upper end of the slide rod 332 is fixedly connected to the support block 331. The support block 331 has a U-shaped groove that mates with the drill rod. The roller 333 is rotatably mounted on the lower end of the support block 331. The control ramp 334, which is slidably connected to the roller 333, is fixedly mounted on the front end of the support slide rail 311. When the support slide rail 311 moves under the storage box 2, the roller 333 rolls on the support slide rail 311, causing the support block 331 to rise. When the support slide rail 311 moves out from under the storage box 2, the roller 333 rolls out from the support slide rail 311 along the control ramp 334, causing the support block 331 to automatically descend.

[0031] The lifting and unloading assembly 34 includes a lifting block 341, a lifting cylinder 342, and a guide rod 343. The lifting cylinder 342 is fixedly connected to the translation plate 312, and the output end of the lifting cylinder 342 is fixedly connected to the lifting block 341. The upper end of the guide rod 343 is fixedly connected to the lifting block 341, and the lower end of the guide rod 343 is slidably connected to the translation plate 312. The lifting block 341 has a V-shaped groove for receiving drill rods. The lifting cylinder 342 can drive the lifting block 341 to move vertically under the limiting action of the guide rod 343.

[0032] In this invention, when a drill rod needs to be added, the translation component 31 moves the clamping support component 32 to the lower side of the corresponding storage compartment. First, the lifting block 341 lifts the drill rod at the bottom of the storage compartment. Then, the side push cylinder 23 controls the limiting block 24 to retract and avoid the drill rod. The lifting block 341 drives the drill rod to slowly fall onto the support block 331, and the side push cylinder 23 controls the limiting block 24 to extend into the second lowest end of the drill rod in the storage compartment to limit it. Subsequently, the flipping frame 324 flips to make the fixed clamping wheel 322 and the movable clamping wheel 322 rotate. The holding wheel 325 cooperates to clamp and limit the drill rod; the translation component 31 controls the drill rod to move between the chuck 11 and the power head 12, and the auxiliary support component 33 automatically moves down to avoid the drill rod, so that the chuck 11 and the power head 12 can cooperate with the drill rod. The fixed clamping wheel 322 and the movable clamping wheel 325 still support the drill rod to prevent the drill rod from deforming due to the excessive length of the suspended part. As the power head 12 gradually moves towards the chuck 11, the translation component 31 controls the clamping support component 32 to achieve an automatic avoidance effect.

[0033] When it is necessary to unload the drill rod, the fixed clamping wheel 322 and the movable clamping wheel 325 first clamp the drill rod together. The translation component 31 drives the drill rod to move downwards towards the storage box 2. The support block 331 automatically moves upwards to lift the drill rod, while the flip shaft 323 flips to release the drill rod from the movable clamping wheel 325. After the drill rod moves to the bottom of the set storage compartment, the lifting block 341 lifts the drill rod on the support block 331 upwards until the drill rod abuts against the bottommost drill rod in the storage compartment. At this time, the side push cylinder 23 controls the limit block 24 to retract, and then the lifting block 341 can lift the drill rod into the storage compartment, making the drill rod the bottommost drill rod in the storage compartment. Finally, the side push cylinder 23 controls the limit block 24 to extend and limit the drill rod, realizing automatic unloading of the drill rod.

[0034] In this invention, the storage box 2 and the frame 10 are integrated. The independent storage compartments allow the drill rods to be arranged in a matrix-like dense arrangement within the storage box 2, which significantly increases the capacity of the storage box 2 and reduces the number of times drill rods need to be added to the storage box 2 during a single drilling operation. The matrix arrangement of the drill rods also facilitates the recording of the number and position information of the drill rods in the drill rod box, which is beneficial for controlling the lateral position of the support slide rail 311. In this application, the vertical movement of the drill rods is controlled separately by gravity, the lifting and unloading assembly 34, and the side push cylinder 23, while the lateral movement of the drill rods is controlled by the translation assembly 31. This allows the drill rod loading and unloading mechanism 3 to achieve the transfer of drill rods even when the installation space is limited. At the same time, it can effectively prevent the position of the drill rods from shifting during the clamping process, so as to achieve a precise conveying effect of the drill rods. The overall structure is compact and simple, and easy to manufacture, assemble, and maintain.

[0039] In this invention, when the drill rod needs to be recycled, the cleaning block 417 is controlled by the centering drive component to closely adhere to the surface of the drill rod to achieve a wiping effect. Multiple cleaning blocks 417 are staggered on the surface of the drill rod to achieve a thorough wiping effect without dead angles. At the same time, cleaning liquid continuously flows onto the drill rod to soften the dirt on the surface. Then, the drill rod is moved into the rotating drum 422, and the surface of the drill rod is continuously brushed by the rotation of the rotating drum 422. Then, clean water is sprayed onto the surface of the drill rod through the nozzle 424 to achieve an all-round, thorough cleaning effect. Finally, the surface of the drill rod is dried by the dryer 44 to prevent the drill rod from rusting.
