Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for geological drilling rotary drilling rigs, and specifically to a coring auxiliary equipment for geological drilling rotary drilling rigs. Background Technology

[0002] Geological rotary drilling rigs are specialized equipment widely used in mineral resource exploration, geological structure research, oil and gas extraction, geothermal energy development, engineering construction, hydrology, and environmental fields. Their mature mechanical structure design results in a low failure rate, making them suitable for long-term stable operation, hence their high usage rate in the geological industry. However, in actual operation, numerous problems arise during the installation and disassembly of drill rods and core tubes, causing considerable inconvenience.

[0003] Currently, drill pipe installation and removal mainly rely on conventional pipe wrenches. Pipe wrenches can only be rotated half-turns to tighten or loosen the drill pipe. This method is not only inefficient, but also prone to slippage when the drill pipe surface is covered with drilling fluid, groundwater, silt, or other impurities, leading to difficulty in operation and potentially damaging the drill pipe threads. Furthermore, when the threads at the drill pipe connection are stuck, it is difficult to disassemble smoothly using only pipe wrenches, requiring the use of other auxiliary tools, further increasing the complexity and time cost of the operation.

[0004] The installation and removal of core tubes mainly rely on manual labor to lift them to the control platform or erect them in the drilling rig. For large-diameter core tubes (such as Φ150mm and above), their weight is significant, and combined with the weight of the core itself during coring, manual lifting and placement poses considerable safety hazards. Workers are prone to slipping the core tube due to improper force or coordination errors, causing injury or equipment damage. Furthermore, manual lifting and placement of core tubes is not only physically demanding but also prone to inefficiency due to frequent operations, affecting the overall drilling progress.

[0005] In order to solve the above-mentioned existing problems, improve the efficiency of drill pipe installation and disassembly and core tube handling, reduce the intensity of manual operation and reduce safety risks, this application proposes a core sampling auxiliary device for geological drilling rotary drilling rigs. Utility Model Content

[0006] This utility model provides an auxiliary device for coring in geological drilling rotary drilling rigs.

[0007] The specific technical solution is as follows:

[0008] A core sampling auxiliary device for a geological drilling rotary drilling rig includes a drill rod knob and a core tube auxiliary carriage. The drill rod knob can be rotated continuously to tighten or loosen the drill rod, and the core tube auxiliary carriage can realize the automatic core tube retrieval and drilling functions.

[0009] Furthermore, preferably, the drill rod knob includes an outer ring handle and a drill rod clamp. The drill rod clamp is a U-shaped component composed of a clamping plate and two side plates. Its U-shaped open end is connected to both ends of the outer ring handle by two connecting rods to form a fan-shaped opening. A fixing rod is connected between the clamping plate and the outer ring handle.

[0010] Furthermore, preferably, two reinforcing rods are symmetrically connected between the two side plates and the outer ring handle to enhance structural stability.

[0011] Furthermore, preferably, the core tube auxiliary vehicle includes a track and a trolley. The bottom of the trolley is equipped with rollers, which are slidably mounted on the track. The top of the trolley is provided with a slot along the track direction, and a baffle is vertically provided at one end of the slot. A winch rope is connected to the end of the trolley away from the baffle, and the other end of the winch rope is fixed to the shaft of a winch. The winch is mounted on the track, and a motor is provided on one side of the winch. The output end of the motor is connected to the shaft of the winch.

[0012] Furthermore, preferably, hooks are provided at the ends of both rails near the winch for securing the rails.

[0013] Furthermore, preferably, the track is concave in shape.

[0014] Furthermore, preferably, the length of the track is greater than the length of the core tube.

[0015] The beneficial effects of this utility model are:

[0016] This invention, through the innovative design of a drill pipe knob and a core tube auxiliary trolley, achieves highly efficient collaborative operation between the two. Focusing on the two key aspects of drill pipe installation and disassembly and core tube transportation in geological drilling operations, it successfully overcomes the problems of low efficiency and numerous safety hazards in traditional operation modes, comprehensively improving the efficiency, safety, and smoothness of geological drilling operations. Specifically, the drill pipe knob, with its unique structural design, can quickly complete the tightening or loosening of drill pipes. Compared to the traditional method of relying on pipe wrenches to turn half a turn at a time, it significantly shortens the time required for drill pipe installation and disassembly, thereby powerfully promoting a significant improvement in the overall efficiency of drilling operations. The core tube auxiliary trolley, through the ingenious cooperation of components such as tracks, trolleys, and motor-driven winches, achieves automated transport of core tubes. Operators only need to place the core tube on the trolley and control the motor via a remote control button to easily complete the automatic core tube retrieval and lowering functions, eliminating the need for manual lifting and placing, greatly improving the automation level of the operation, effectively reducing the intensity of manual labor, and eliminating the safety hazards caused by manual handling of core tubes.

[0017] Furthermore, the overall design of this invention is simple and practical, facilitating on-site processing and installation, and enabling it to quickly adapt to various complex geological drilling environments and different operational requirements. Each component of the equipment possesses excellent adjustability and optimizability, allowing for flexible adaptation to specific application scenarios, demonstrating high versatility and applicability. This enables the invention to be widely applied in various geological drilling projects, possessing significant practical value and broad application prospects. It is expected to bring considerable economic and social benefits to the geological drilling industry, promoting technological progress and sustainable development within the sector.

[0022] To make the technical problems and solutions solved by this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0023] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figure 1-3 As shown, this utility model relates to a core sampling auxiliary device for a geological drilling rotary drilling rig, including a drill rod knob and a core tube auxiliary vehicle.

[0026] like Figure 1 As shown, the drill pipe knob 1 includes an outer ring handle 11 and a drill pipe clamp 12. The drill pipe clamp 12 is a U-shaped component composed of a clamping plate 120 and two side plates 121. Its U-shaped opening is connected to both ends of the outer ring handle 11 via two connecting rods 13, forming a fan-shaped opening. A fixing rod 14 connects the clamping plate 120 and the outer ring handle 11. The two connecting rods 13 and the fixing rod 14 securely connect the drill pipe clamp 12 to the outer ring handle 11. Furthermore, two reinforcing rods 15 are symmetrically connected between the two side plates 121 and the outer ring handle 11 to further enhance structural stability.

[0027] During manufacturing, the outer ring handle 11 is made of threaded steel to increase friction and prevent slippage during operation; the connecting rod 12, fixing rod 14 and reinforcing rod 15 can be made of threaded steel or ordinary smooth steel bars; the drill rod clamp 12 is made of steel plate to increase the contact area with the drill rod and ensure a firm clamping; the size of the opening formed by the drill rod clamp 12 matches the diameter of the drill rod to accommodate drill rod designs of different specifications.

[0028] Working principle: The operator places the drill rod clamp 12 onto the outer surface of the drill rod's clip and begins to rotate the outer ring handle 11. The rotation of the outer ring's large wheel drives the inner ring's small ring drill rod clamp 12 to rotate synchronously, causing the two side plates 121 to hold the drill rod and rotate together. The entire process can be repeated several full rotations, thus quickly and effortlessly completing the tightening or loosening of the drill rod.

[0029] like Figure 2-3 As shown, the core tube auxiliary vehicle 2 includes a track 21 and a trolley 22. Rollers 23 are installed at each of the four corners of the bottom of the trolley 22, and the rollers 23 are slidably mounted on the track 21. With the cooperation of the rollers 23 and the track 21, the trolley 22 can reciprocate along the track 21. It should be noted that the length of the track 21 is generally longer than the length of the core tube.

[0030] The top of the trolley 22 is provided with a slot 24 along the direction of the track 21 for fixing the core tube; a baffle 25 is provided vertically at one end of the slot 24 to prevent the core tube from sliding out.

[0031] The end of the trolley 22 furthest from the baffle 25 is connected to a winch rope 26 (made of steel cable). The other end of the winch rope 26 is fixed to the shaft of the winch 27. The winch 27 is mounted on the track 21, and a motor 28 is mounted on one side of the winch 27. The output end of the motor 28 is connected to the shaft of the winch 27. The motor 28 drives the shaft of the winch 27 to rotate, thus moving the trolley 22 forward or backward.

[0032] To facilitate the fixing of the rails 21, hooks 29 are provided at the ends of both rails 21 near the winch 27 to fix the rails 21 and prevent them from shifting or deviating.

[0033] During manufacturing, the track 21 is made of U-shaped steel plate (such as channel steel), and the rollers 23 at the bottom of the trolley 22 are stuck in the groove to ensure that the trolley 22 slides smoothly on the track 21 and prevents it from derailing.

[0034] Working principle: First, hook the two hooks 29 of the track 21 onto the drilling rig platform to fix the core tube auxiliary vehicle.

[0035] During drill bit retrieval, the initial position of the trolley 22 is near the beginning of the track 21 on the drilling rig platform. The bottom end of the core tube, which has left the borehole, is placed in the slot 24 of the trolley 22, with the baffle 25 acting as a barrier to prevent the core tube from slipping out. Then, the hoisting mechanism and motor 28 on the drilling rig are activated. The hoisting mechanism moves one end of the core tube downwards, while the motor 28 drives the winch 27 to rotate in the opposite direction, extending the winch rope 26. Under the weight of the core tube, the trolley 22 and the core tube above it move together away from the drilling rig platform until the core tube is completely transferred from the drilling rig platform to the trolley 22, at which point it can be removed.

[0036] During drilling, the initial position of the trolley 22 is at the end of the track 21, away from the drilling rig platform. One end of the core tube is placed in the slot 24 on the trolley 22, and the other end is connected to the hoist. Then, the hoisting mechanism and motor 28 on the drilling rig are started. The hoisting mechanism moves one end of the core tube upwards, while the motor 28 drives the winch 27 to rotate, retracting the winch rope 26 and moving the trolley 22 and the core tube above it together towards the drilling rig platform until the core tube detaches from the trolley and stands upright on the drilling rig platform. Afterwards, the core tube is connected to the drill pipe, and drilling can begin.

[0037] In practical use, a remote control can be equipped to control the movement of the crane and motor 28, completing the automatic core tube retrieval and lowering process. This equipment saves manpower during core tube retrieval and lowering, solves the problem of lifting large-diameter core tubes, eliminates the safety hazards of manually lifting core tubes, and improves operational efficiency and safety.

[0038] The present invention has been described in detail above through specific and preferred embodiments. However, those skilled in the art should understand that the present invention is not limited to the embodiments described above. Any modifications or equivalent substitutions made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
