Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of lithium mine drilling, and in particular relates to a drilling device for pegmatite type lithium mine. BACKGROUND

[0002] In the field of drilling engineering today, especially when exploring and exploiting deep stratum resources such as high-strength pegmatite type lithium mine, drilling depth is one of the key factors to obtain accurate geological information and valuable mineral resources. In order to reach a sufficient depth, it is often necessary to achieve this goal by connecting multiple drill rods.

[0003] However, the current commonly used drill rod connection method is a threaded connection method. In actual application, each time the drill rod is connected, the operation is extremely tedious. The operator needs to spend a lot of time and effort to accurately align the threads and carefully tighten them step by step to ensure the stability of the connection; at the same time, the drill rod needs to be rotated, which is tedious and time-consuming. In deep hole drilling projects, due to the large number of drill rods that need to be connected, the time spent on this seemingly simple operation accumulates a lot, which seriously hinders the overall drilling progress. This inefficient connection method greatly limits the rapid and continuous connection and growth of the drill rod, making it difficult to achieve the desired drilling depth. CONTENT OF THE INVENTION

[0017] A plurality of locking rods are arranged in the mounting space at intervals, a through hole is formed in the second drill rod, a corresponding locking hole is formed in the extension, and the locking rod can be inserted into the locking hole through the through hole to lock the extension;

[0018] A guide rod is connected to the inner wall of the mounting space and is inserted with the locking rod, used for supporting the locking rod when all the locking rods are in the mounting space, and the mounting direction of the guide rod is parallel to the moving direction of the locking rod inserted into the locking hole;

[0019] An elastic member is arranged in the mounting space and used for rebounding the locking rod to the locking hole, and a connecting rope is wound in each rope groove of the rotating drum and is connected to the end of the locking rod, wherein rotating the rotating drum can make the connecting rope retract the locking rod away from the locking hole, and after being positioned, the locking rod compresses the elastic member;

[0020] A guide member is used for guiding the connecting rope to pull the connecting rope in the moving direction of the locking rod.

[0021] In the drilling equipment for pegmatite type lithium ore provided in the application, a striking metal piece is further connected to the locking hole in a floating manner, when the locking rod is inserted into the locking hole by the elastic member, the locking rod strikes the striking metal piece to produce a striking sound, and the locking rod continues to move to press the striking metal piece against the bottom of the locking hole.

[0022] In the drilling equipment for pegmatite type lithium mine provided by the application, the impact metal sheet is connected to the inner wall of the locking hole by an elastic piece and is located at the bottom position.

[0023] In the drilling equipment for pegmatite type lithium mine provided by the application, the elastic piece comprises a spring, the guide piece is located in the inner ring of the spring, and the connecting rope passes through the gap of the spring into the guide piece.

[0029] 2. In the drilling of high-strength pegmatite type lithium mine, in view of the defect that the traditional threaded connection is easy to loosen under complex stress, a locking mechanism is arranged in the mounting space of the second drill rod and is specially used for locking the extension inserted into the mounting hole and the second drill rod, which is quite different from the existing stable mode relying only on threaded connection and greatly enhances the reliability of the connection. The traditional drill rod connection mode lacks consideration of complex drilling environments, and in the high-strength pegmatite type lithium mine environment, external impurities are easy to affect the connection structure. The locking mechanism is arranged in the mounting space and on the surface of the second drill rod, which can effectively seal the mounting space and prevent impurities from entering, which is a deficiency of the prior art.

[0040] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, not all embodiments. It should be noted that the embodiments and features in the embodiments in the present disclosure can be combined, separated, interchanged and / or rearranged without conflict. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0041] In the drawings, the size and relative sizes of parts can be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be carried out in different ways, a specific process sequence can be performed in a different order from the described order. For example, two consecutively described processes can be performed substantially simultaneously or in an order opposite to the described order. Also, like reference numerals denote like parts throughout the specification.

[0042] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. Furthermore, to the extent that the terms "including," "includes," "having," "has," "a," "an," "one," and / or "said" are used in the detailed description and / or claims, such terms are intended to be inclusive (i.e., in a manner that says that one), unless explicitly indicated to the contrary.

[0043] One specific embodiment of the present utility model, such as Figures 1-3 As shown in the figure, a kind of drilling equipment for pegmatite lithium mine is disclosed, including first drill rod 10, end portion has the extension 11 of polygonal section;Second drill rod 20, corresponding with the end portion of first drill rod 10 is equipped with the mounting hole adapted to extension 11, second drill rod 20 is also provided with installation space 201, installation space 201 is immediately adjacent to mounting hole, and installation space 201 penetrates the lateral surface of second drill rod 20;Locking mechanism 30, it is set in installation space 201, for locking together with the extension 11 of being installed to mounting hole and second drill rod 20;Sealing mechanism 40, it is set in installation space 201, and located second drill rod 20 surface, for sealing installation space 201.

[0044] The extension part 11 is a regular hexagonal structure. In this embodiment, the polygonal cross-section extension part 11 of the first drill pipe 10 is inserted into the mounting hole of the second drill pipe 20, and the preliminary positioning is achieved by matching the shapes of the two. Then the extension part 11 and the second drill pipe 20 are stably connected by the locking mechanism 30, which ensures that the two will not separate during drilling. The sealing mechanism 40 is used to protect the components in the mounting space 201 and prevent foreign matter from entering and affecting the normal operation of the locking mechanism 30. Compared with the traditional threaded connection method, this design does not require tedious thread alignment and tightening operations. Through the matching of the polygonal extension part 11 and the mounting hole, the drill pipe connection can be quickly achieved, greatly improving the connection efficiency. The locking mechanism 30 ensures the stability of the connection, and adapts to the complex stress conditions in the drilling of high-strength pegmatitic lithium ore. The sealing mechanism 40 can prolong the service life of the equipment and reduce failures. At the same time, the workers do not need to surround the drill pipe and rotate the drill pipe for replacement and installation, reducing physical exertion.

[0045] In some embodiments, the sealing mechanism 40 includes a sliding cover 401 that slides along the length direction of the second drill pipe 20. The sliding cover 401 is in sliding connection with a retraction groove opened on the second drill pipe 20, and a magnet piece is arranged on the top of the sliding cover 401 and in the retraction groove, so that the sliding cover 401 can be attracted when it is retracted.

[0046] When the locking mechanism 30 and other internal components need to be operated, slide the sliding cover 401 along the length direction of the second drill pipe 20 to open the mounting space 201. The sliding cover 401 can be attracted when it is retracted. It is convenient to operate, and after the operation is completed, the sliding cover 401 is pushed back. A corresponding magnet assembly can also be arranged at the bottom of the sliding cover 401, so that the sliding cover 401 can be attracted and fixed by the magnet when it seals the mounting space 201. The sliding cover 401 is fixed in the closed position to achieve the sealing of the mounting space 201.

[0047] The outside of the sliding cover 401 is provided with a plurality of notches 402. The notches 402 increase the friction of the surface of the sliding cover 401, which is convenient for the operator to manually operate the sliding of the sliding cover 401. In the complex conditions of oil stains, water stains and the like on the drilling site, the notches 402 can enable the operator to more stably grasp the sliding cover 401 for operation. Even if wearing gloves, the sliding cover 401 can be easily slid, improving the convenience and safety of operation.

[0048] In some embodiments, the locking mechanism 30 includes a rotating clamping shaft 301 rotatably connected to the inner wall of the mounting space 201; a coil spring 302, one end of which is clamped on the rotating clamping shaft 301 and sleeved thereon; a rotating drum 303 sleeved outside the coil spring 302, the other end of which is connected to the rotating drum 303, and a plurality of rope grooves spaced apart on the rotating drum 303; a plurality of locking rods 304 spaced apart within the mounting space 201, a through hole being provided in the second drill rod 20, and a corresponding locking hole being provided on the extension 11, the locking rods 304 being able to pass through the through hole into the locking hole to lock the extension 11; and a guide rod 3. 05, connected to the inner wall of the installation space 201, intersecting with the locking rod 304, used to support the locking rod 304 when it is fully inside the installation space 201, the installation direction of the guide rod 305 is parallel to the moving direction of the locking rod 304 when it is inserted into the locking hole; elastic element, set in the installation space 201, used to spring the locking rod 304 back to the locking hole; connecting rope 307, wound in each rope groove of the rotating drum 303 and connected to the end of the locking rod 304, wherein, rotating the rotating drum 303, the connecting rope 307 can drive the locking rod 304 to retract away from the locking hole, and after it is in place, the locking rod 304 compresses the elastic element.

[0049] The elastic element causes the locking rod 304 to tend to move towards the locking hole. When it is necessary to connect the drill rod, the rotating drum 303 is rotated, the coil spring 302 stores force, and the rotating drum 303 pulls the locking rod 304 back into the installation space 201 via the connecting rope 307. At this time, the extension 11 of the first drill rod 10 is inserted into the installation hole of the second drill rod 20. Then the rotating drum 303 is released, and under the action of the elastic element, the locking rod 304 passes through the through hole and inserts into the locking hole of the extension 11, thus locking. The guide rod 305 is used to limit the movement direction of the connecting rope 307 to ensure that it accurately moves the locking rod 304.

[0050] This locking mechanism 30 is ingeniously designed, controlling the extension and retraction of the locking rod 304 by rotating the drum 303, making operation relatively simple. Compared with traditional connection methods, it can quickly lock and unlock the drill pipe, improving connection efficiency. Meanwhile, the cooperation between the elastic element and the guide rod 305 ensures the reliability of the locking, adapting to complex stress conditions during drilling.

[0051] Compared to a single locking rod 304, multiple locking rods 304 can disperse the force on the drill pipe connection, making the stress distribution more uniform and preventing the single locking rod 304 from deforming or being damaged under complex external forces (such as torque, impact force and axial force in drilling high-strength pegmatite).

[0052] A single locking rod 304 provides only one locking point, making it susceptible to loosening due to uneven stress or external impact. Multiple locking rods 304 provide multi-directional locking, forming a stable network that significantly enhances connection stability and reduces the possibility of loosening. If a single locking rod 304 fails, the drill pipe connection can be severely damaged or even separated. Multiple locking rods 304 provide redundancy, preventing immediate disconnection of the drill pipe in the event of partial failure, thus reducing the risk of accidents. The combined effect of multiple locking rods 304 enhances connection strength, enabling them to withstand greater tensile, compressive, and torque forces, ensuring a stable drill pipe connection in high-strength pegmatite lithium mine drilling.

[0053] In some embodiments, an impact metal plate is also floatingly connected inside the locking hole. When the locking rod 304 is pushed into the locking hole by the elastic member, the locking rod 304 impacts the metal plate, producing an impact sound, and the locking rod 304 continues to move, pressing the impact metal plate against the bottom of the locking hole.

[0054] When the locking lever 304 moves towards the locking hole under the action of the elastic element, it strikes the impact metal plate of the floating connection, producing an impact sound to indicate to the operator that the locking action is complete. Subsequently, the locking lever 304 continues to move, pressing the impact metal plate against the bottom of the locking hole, making the connection more secure.

[0055] The impact sound can serve as a direct feedback signal, allowing operators to confirm whether the drill pipe is properly locked.

[0056] The impact metal plate is connected to the inner wall of the locking hole by an elastic element and is located at the bottom.

[0057] The elastic element allows the impact metal plate to have a certain floating space within the locking hole. When it is impacted by the locking rod 304, it can generate displacement and impact sound. At the same time, as the locking rod 304 continues to move, it can be pressed against the bottom. Furthermore, the elastic element can buffer the impact force and reduce damage to the components.

[0058] The flexible connection design ensures the impact function is realized while also buffering the impact force, protecting the locking lever 304 and the impact metal plate, and extending the service life of the components. At the same time, it ensures the correct position and function of the impact metal plate during the locking process, enhancing the reliability and stability of the locking mechanism.

[0059] In some embodiments, the elastic element in the locking mechanism 30 includes a spring 306, a guide 308 located in the inner ring of the spring 306, and a connecting rope 307 passing through the gap in the spring 306 into the guide 308.

[0060] Spring 306 acts as an elastic element to provide the locking lever 304 with a rebound force, causing it to move towards the locking hole. Guide element 308 is located in the inner ring of spring 306 and guides the connecting rope 307, ensuring that the direction of force of the connecting rope 307 is accurate when pulling the locking lever 304. At the same time, the connecting rope 307 passes through the gap of spring 306 to avoid interference.

[0061] The guide member 308 includes a cylinder 309 with an opening on its outer side. A connecting rope 307 enters the cylinder 309 through the opening, extends from the end of the cylinder 309, and is connected to the locking rod 304. The cylinder 309 and the locking rod 304 are collinear.

[0062] The connecting rope 307 enters from the opening on the outer side of the cylinder 309, extends along the interior of the cylinder 309 to its end, and connects to the locking rod 304. Because the cylinder 309 and the locking rod 304 are collinear, the direction of the tension force exerted by the connecting rope 307 on the locking rod 304 is consistent with the direction of movement of the locking rod 304, accurately controlling the extension and retraction of the locking rod 304. Guided by the cylinder 309, the accuracy of the tension direction of the connecting rope 307 is ensured, allowing the locking rod 304 to move more stably and accurately between the installation space 201 and the locking hole, improving the working accuracy and reliability of the locking mechanism 30.

[0063] The openings of the multiple cylinders 309 are offset from each other, ensuring that the connecting ropes 307 do not interfere with each other when passing through the cylinders 309. Designing the openings of the multiple cylinders 309 in a relatively offset manner avoids interference between the connecting ropes 307 and the cylinders 309 when multiple locking rods 304 and connecting ropes 307 are working simultaneously, ensuring that each connecting rope 307 can smoothly apply tension to its corresponding locking rod 304. This design optimizes the simultaneous operation of multiple locking rods 304, ensures the normal operation of the entire locking mechanism 30 under complex conditions, improves the stability and reliability of the equipment, and avoids locking failures caused by interference from the connecting ropes 307.

[0064] This application also includes a knob 50 connected to the inner wall of the rotating drum 303, with the knob 50 facing the outlet of the mounting space 201.

[0065] The operator rotates the knob 50 to drive the drum 303 to rotate, thereby controlling the movement of the connecting rope 307 and the locking rod 304. The knob 50 is located at the exit of the installation space 201 for easy operator access. The design of the knob 50 provides a convenient operating method, allowing the operator to easily control the rotation of the drum 303, thus locking and unlocking the drill pipe. This improves operational convenience and ease of use, especially in complex operating environments such as downhole drilling.

[0066] The above specific embodiments further illustrate the purpose, technical solution and beneficial effects of this application. It should be understood that the above are only specific embodiments of this application and are not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
