Description

Technical Field

[0001] The present invention relates to a drilling rig, in particular to an electric drive drilling rig. Background Art

[0002] Petroleum exploration is a complex and systematic process, primarily divided into phases including geological surveys, geophysical exploration, drilling exploration, and oil and gas field development. Drilling rigs are closely and indispensable to petroleum exploration. Drilling rigs are key tools for achieving core objectives in the process, and their role runs throughout the entire drilling process. There are many types of drilling rigs, among which rotary drilling rigs are a common type. Rotary drilling rigs serve as auxiliary equipment in petroleum exploration, used for shallow geological exploration and sample collection.

[0003] Existing rotary drilling rigs rapidly obtain underground rock and soil samples through the rotation of the drill pipe and drill bit, providing fundamental data for geological structure analysis. Their efficiency and flexibility make them suitable for shallow geological exploration. The power head, the core component of the rotary drilling rig, is directly connected to the upper end of the drill pipe via its main shaft. It transmits the torque and pressure generated by the motor to the drill pipe, thereby driving the drilling tools (such as the drill bucket and auger bit) to rotate and cut the formation. The wire rope in the rotary drilling rig's hoisting system is typically connected to the power head via a hoist, thereby driving the entire drill pipe and drill bit to rise and fall.

It can not only clean the drilling tool mechanism for its subsequent use, but also collect the cleaned mud for recycling. No human intervention is required throughout the process, thereby improving the overall safety of the drilling rig. The mud cleaning station is staggered with the drilling station to prevent mud from re-entering the well. In addition, the mud cleaning component can drain the mud washed down by the water flow. After the drainage is completed, the mud can be compacted to form soil blocks, and then pushed out when the soil blocks are subsequently sent out, making it convenient for external robots to pick up, recycle and transport the soil blocks. No human participation is required in the soil processing throughout the process. The overall degree of automation is high, which improves safety and work efficiency.

[0043] In this embodiment, the drainage filtering mechanism specifically includes: a mud collecting trough 41 provided inside the mud collecting box 37, a lifting plate 42 movably connected to the inside of the mud collecting trough 41, and a plurality of water outlet holes 43 are provided on the bottom end surface of the lifting plate 42, and a plug column 44 matching the water outlet hole 43 is fixedly connected to the position of the bottom end surface of the mud collecting trough 41 corresponding to the water outlet hole 43, and a limiting column 45 is fixedly connected to the position of the bottom end surface of the mud collecting trough 41 near the edge, and a second spring column 46 is sleeved on the outside of the limiting column 45, and the two ends of the second spring column 46 are respectively fixedly connected to the bottom end surface of the mud collecting trough 41 and the bottom end surface of the lifting plate 42, a circular hole 47 is provided at the center of the bottom end surface of the mud collecting trough 41, and a lifting cylinder 15 is embedded in the center of the bottom end surface of the groove of the concave platform 40, and the top output shaft of the lifting cylinder 15 matches the circular hole 47. Compared with the traditional leak-hole drainage, the drainage filtering mechanism set up in this application adds a plug 44 under the water outlet 43. When the soil is compacted, the plug 44 can block the water outlet 43 to prevent the soil from being pressed into the water outlet 43 and affecting the next drainage work, eliminating manual hole cleaning and improving safety and work efficiency.

[0044] In this embodiment, the compacting member specifically includes a hydraulic cylinder 49 fixed at the center of the top surface of the through groove 48. The bottom output shaft of the hydraulic cylinder 49 is fixedly connected to a pressing plate 50, and the pressing plate 50 matches the mud collecting trough 41.

[0045] In this embodiment, the drive mechanism specifically includes: strip grooves 3 defined on both sides of the bottom surface of the movable platform 2; first linear guides 4 fixedly connected to the top surface of the support platform 1 corresponding to the strip grooves 3; and two parallel first linear motors 5 movably connected to the top of the first linear guides 4. The tops of the first linear motors 5 are fixedly connected to the top walls of the strip grooves 3. The drive mechanism is capable of driving the movable platform 2 to move on the top surface of the support platform 1.

[0046] In this embodiment, the anti-soil-back mechanism specifically includes: a telescopic cylinder 51 embedded in the bottom end of one side of the support platform 1; the output shafts of the two telescopic cylinders 51 are fixedly connected to a support plate 52; and two parallel side plates 53 are fixedly connected to one side of the support plate 52; a sealing plate 54 is provided between the two side plates 53; a lifting groove 55 is formed on the opposite surface of the two side plates 53, and a lead screw 57 is rotatably connected inside the lifting groove 55; lifting blocks 56 are fixedly connected to the two side surfaces of the sealing plate 54 corresponding to the lifting groove 55, and the lifting blocks 56 are located in the lifting groove 55 and are threadedly connected to the lead screw 57; a stepper motor 58 is fixedly connected to the top surface of the side plate 53 corresponding to the lead screw 57, and the output shaft of the stepper motor 58 is fixedly connected to the corresponding lead screw 57. The anti-soil-back mechanism can seal the drill hole after the drilling tool is lifted out after a rotary drilling operation is completed, preventing the accumulated soil around the drill hole from falling back into the drill hole, thereby improving drilling efficiency. At the same time, sealing the drill hole further improves safety.

[0047] In this embodiment, the bottom of the sealing plate 54 is connected to a vertical rod 59, and the outer wall of the vertical rod 59 is evenly connected to multiple bulldozer blades 60. A hydraulic telescopic rod 61 is installed between the inner wall of the bulldozer blade 60 and the outer wall of the vertical rod 59. After the sealing plate 54 moves to the top of the borehole and moves downward to a preset height, the horizontal position of the sealing plate 54 is adjusted using the telescopic cylinder 51 so that the vertical rod 59 is directly above the borehole. The hydraulic telescopic rod 61 extends, thereby driving the bulldozer blade 60 to push the soil accumulated around the top of the borehole, thereby clearing the soil around the borehole and facilitating the stable placement of the sealing plate 54 when it is subsequently used to seal the top of the borehole. At the same time, when the sealing plate 54 covers the top of the borehole to seal, the vertical rod 59 is inserted into the borehole, and the hydraulic telescopic rod 61 drives the bulldozer blade 60 to move toward the inner wall of the borehole, ultimately causing the bulldozer blade 60 to abut against the inner wall of the borehole. The plurality of bulldozer plates 60 abut against the inner wall above the borehole, which can improve the bearing capacity of the borehole inner wall opening and prevent the accumulation of a large amount of soil and other objects above the hole opening, causing the hole opening to undergo large deformation and collapse.

[0048] The working principle of the present invention is: when in use, first, the electric drill rig is installed at the place of use, and then the wire rope 10 is released by the winch 11. As the wire rope 10 is released, the drilling tool mechanism descends steadily. During the process, the drive motor 13 runs to drive the drill rod 14, the rotary drill bit 16 and the cover 17 to rotate, and the movable bracket 12 follows and descends to improve the stability of the drive motor 13. When the rotary drill bit 16 contacts the target ground, the rotating rotary drill bit 16 starts rotary drilling. After a period of time, the wire rope 10 is reeled in by the winch 11, driving the drilling tool mechanism to rise from the well, and the rotary drill bit 16 and the cover 17 carry a large amount of soil.

[0049] It should be noted that, during the process of retracting and releasing the wire rope 10, the wire rope 10 passes through the guide groove 8 of the guide seat 7, wherein the guide wheel 9 guides the wire rope 10 and reduces the friction resistance, and the guide detection rope stop component can perform real-time detection on the wire rope 10, and take emergency measures to urgently stop the wire rope 10 when the wire rope 10 is abnormal. The specific working process of the guide detection rope stop component is: when the wire rope 10 moves along the first through hole 20 of the detection box 19, the camera 21 embedded on the inner wall of the first through hole 20 collects the surface image of the wire rope 10 and sends the image to the background control terminal, which identifies and analyzes the collected image to determine whether there is any damage abnormality on the surface of the wire rope 10. Among them, image recognition and analysis is an existing well-known technology, so it will not be elaborated here. If the wire rope 10 is damaged abnormally, the emergency rope stop mechanism is given a rope stop command through the background control terminal. After the emergency rope stop mechanism receives the rope stop command, the second linear motor 33 runs along the second linear guide rail 32 to move toward the rope stop box 22. During the process, the conical head 30 on the moving seat 29 extends into the conical groove 23 of the rope stop box 22. As the conical head 30 further extends into the conical groove 23, the conical head 30 presses against the clamping plate 25 and moves accordingly. The clamping plate 25 moves in the oblique groove 24 along the optical axis 27, the first spring column 28 is compressed, and the clamping plate 25 gets closer and closer to the wire rope 10. Finally, the rubber pads 26 of each clamping plate 25 fully support the wire rope 10 from multiple angles, thereby achieving the purpose of rope stopping. This rope stopping scheme not only has efficient braking effect, but also avoids wear on the wire rope 10. After the rope stop instruction is canceled, the second linear motor 33 runs along the second linear guide rail 32 to return to the initial position, the conical head 30 disengages from the conical groove 23, and the clamping plate 25 releases the wire rope 10 under the elastic force of the first spring column 28, and the braking of the wire rope 10 is eliminated.

[0050] In addition, after the drilling tool mechanism is lifted up from the well, a large amount of mud is carried on the rotary drill bit 16 and the cover body 17. For this reason, the present application provides a mud cleaning treatment component, a support platform 1, and a mobile platform 2, which can be used to clean the mud of the drilling tool mechanism that carries out the mud through a high-pressure water flow. This not only cleans the drilling tool mechanism for its subsequent use, but also collects the cleaned mud for recycling. No human intervention is required throughout the process, which improves the overall safety of the drilling rig. The mud cleaning station is staggered with the drilling station to avoid mud from re-entering the well. The specific mud cleaning process is as follows: first, the drilling tool is lifted up, and the mud is removed from the well. The mechanism is lifted to a preset height, and then the first linear motor 5 operates according to a preset program and moves along the first linear guide rail 4 toward the compacting box 39. During the process, the movable platform 2, the support frame 6, and the drilling mechanism follow the movement. Finally, the drilling mechanism reaches the top of the mud collection box 37, and the rotary drilling bit 16 and the cover body 17 of the drilling mechanism are just located between the water spray heads 38 on both sides. Immediately afterwards, the external high-pressure water source ejects high-pressure water flow toward the rotary drilling bit 16 and the cover body 17 through the water spray heads 38, and the high-pressure water flow flushes down the soil carried on the rotary drilling bit 16 and the cover body 17. The washed-down soil and water fall into the mud collecting trough 41 of the mud collecting box 37 below. The lifting plate 42 in the mud collecting trough 41 supports the fallen soil, while the water in the soil flows through the water outlet 43 to the bottom of the mud collecting trough 41 and out of the mud collecting box 37 through the circular hole 47, thus achieving the purpose of draining the soil. During this process, as the weight of the soil supported by the lifting plate 42 increases, the lifting plate 42 slowly descends along the mud collecting trough 41, compressing the second spring column 46. After the soil is drained, the third linear motor 36 operates according to the preset program and moves along the third linear guide 35 toward the compaction box 39. The mud collecting box 37 follows the movement and finally moves the mud collecting box 37 into the through slot 48 in the compaction box 39 and is located directly below the pressure plate 50. Then, the hydraulic cylinder 49 runs and extends the output shaft to press the pressure plate 50 downward. The pressure plate 50 is pressed into the mud collecting trough 41 to compact the soil therein. During the process, the lifting plate 42 is subjected to external force and falls again, and the second spring column 46 is compressed for the second time until the lifting plate 42 contacts the top of the limit column 45. At this time, the limit column 45 stops the downward trend of the lifting plate 42, and the plug column 44 is just inserted into the water outlet 43, pushing out the soil pressed into the water outlet 43 and sealing the water outlet 43. Compared with the traditional leaky hole drainage, the present application adds a plug column 44 below the water outlet 43, which can block the water outlet 43 through the plug column 44 when compacting the soil, preventing the soil from being pressed into the water outlet 43 and affecting the next drainage work, eliminating the need for manual hole cleaning, and improving safety and work efficiency.

[0051] After the soil in the mud collecting box 37 is compacted, the compacting part returns to its initial state, and the second spring column 46 releases part of its elastic potential energy to lift the lifting plate 42 upward. Then, the third linear motor 36 moves along the third linear guide 35 toward the concave platform 40 according to the preset program, and the mud collecting box 37 follows the movement. Finally, the mud collecting box 37 is sent to the groove of the concave platform 40, and the top output shaft of the lifting cylinder 15 is aligned with the circular hole 47 of the mud collecting box 37. Subsequently, the lifting cylinder 15 runs and extends the output shaft. The top output shaft of the lifting cylinder 15 passes through the circular hole 47 to lift the lifting plate 42 to a preset height. During this process, the second spring column 46 releases its elastic potential energy and is stretched, and the soil blocks on the lifting plate 42 are sent out of the mud collecting trough 41, making it easier for external robots to pick up, recycle and transport the soil blocks. No human participation is required in the whole process of handling the soil. The overall degree of automation is high, which improves safety and work efficiency. After the external robot takes away the soil, the lifting plate 42 retracts downward to the bottom of the mud collecting trough 41 under the action of its own gravity and the elastic force of the second spring column 46.

[0052] It should also be noted that after the drilling tool mechanism is lifted up from the borehole, the soil around the borehole tends to fall back into the borehole. For this reason, the present application sets up an anti-soil-return mechanism, which seals the borehole after the drilling tool mechanism is lifted up after a rotary drilling operation is completed, thereby preventing the accumulated soil around the borehole from falling back into the borehole, thereby improving drilling efficiency. At the same time, sealing the borehole can further improve safety. The specific working process is as follows: the telescopic cylinder 51 operates to retract the output shaft, driving the support plate 52 to move in the direction of the borehole until the sealing plate 54 reaches directly above the borehole. Subsequently, the stepper motor 58 operates to drive the lead screw 57 to rotate, causing the lifting block 56 to slowly descend along the lead screw 57 in the lifting groove 55. During this process, the sealing plate 54 follows and descends until the sealing plate 54 seals the borehole. In the initial state, the sealing plate 54 is at a certain height from the borehole ground. This is to prevent the sealing plate 54 from pushing the soil around the borehole into the borehole during its translation. Before the sealing plate 54 seals the borehole, the bulldozer plate 60 can be used to push out the soil accumulated around the top of the borehole during the rotation process according to actual needs. This can not only facilitate the sealing plate 54 to be placed stably on the top of the borehole for sealing, but also further clean the area around the borehole to prevent soil from entering the borehole again.
