Description

Technical Field

[0001] This utility model belongs to the field of mining drilling rigs and relates to a transfer device for fixing drill rods in the vertical direction. Background Technology

[0002] In today's era of rapid technological advancement, automated drilling rig technology is maturing at an unprecedented pace. Modern automated drilling rigs can now perform a series of operations, including loading and unloading drill rods, drilling, and attitude adjustment, all in a fully automated manner. This technological breakthrough has greatly improved the efficiency and safety of drilling operations and has been widely applied in disaster prevention and control projects such as gas extraction and water exploration, playing a crucial role in ensuring safe production in underground workplaces such as coal mines.

[0003] However, the drill pipe delivery system, a core component of the widely used automated drilling rig technology, still faces some pressing issues. Currently, most automated drilling rigs employ a three-stage drill pipe delivery system consisting of two robotic arms combined with a transfer device. In this system, the transfer device, as a crucial component for the transfer of drill pipe between the two robotic arms, directly impacts the stability and reliability of the entire drill pipe delivery system.

[0004] Existing transfer devices mainly come in two forms: translation and horizontal rotation, and their movement trajectories are limited to the horizontal plane. During operation, the transfer device clamps both ends of the horizontally placed drill rod by moving and rotating in the horizontal plane, thereby ensuring that the drill rod can be accurately aligned with the drill rod box or frame, and realizing the smooth transport of the drill rod. However, this design also brings a significant drawback: existing transfer devices lack vertical fixation.

[0005] Due to the lack of vertical fixation, existing transfer devices are inadequate for drilling operations requiring steep inclination angles. Under steep inclination conditions, the drill rod is subjected to a significant gravitational component in the vertical direction, and existing transfer devices cannot provide effective vertical support for the drill rod. This leads to problems such as swaying, shifting, and even detachment of the drill rod during transport, severely affecting drilling accuracy and quality, and potentially causing safety accidents that threaten the lives of operators.

[0006] Limited by this technological bottleneck, the drilling inclination range of existing automatic drilling rigs is severely constrained. In practical applications, many working conditions requiring large-angle drilling, such as gas extraction under complex geological conditions and deep groundwater exploration, are beyond the reach of existing automatic drilling rigs. This limits the application of automatic drilling rigs in a wider range of fields, preventing them from fully realizing their advantages of automation and high efficiency.

[0007] To overcome this technical bottleneck, it is necessary to propose a transfer device that can fix the drill rod in the vertical direction, further expand the application scope of automatic drilling rigs, and promote the development of drilling technology to a higher level. Utility Model Content

[0008] In view of this, the purpose of this utility model is to provide a vertically fixed drill rod transfer device, which solves the problem that the current drill rod transfer device lacks a drill rod fixing mechanism in the vertical plane, and the drill rod falls off due to tilting motion.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A vertically fixed drill rod transfer device includes a base plate, a support block, a pressure plate, and an axial clamping block. The support block is disposed on the base plate for supporting the drill rod. The axial clamping block is disposed on the base plate and located on both sides of the support block. A pressure plate is rotatably connected to the upper part of the axial clamping block, and the pressure plate is located above the support block. The axial clamping block clamps and fixes the drill rod axially upwards. The axial clamping block includes at least one slider slidably disposed on the base plate. The pressure plate presses the drill rod against the support block.

[0011] Optionally, a sliding cylinder is provided at the bottom of the base plate, and the sliding cylinder is connected to the slider to drive the slider to slide along the length direction of the base plate.

[0012] Optionally, the axial clamping block is rotatably connected to the pressure plate. When the transfer device is in a state of waiting to load or remove the drill rod, the pressure plate rotates upward to open, facilitating the loading or removal of the drill rod.

[0013] Optionally, the pressure plate is also provided with a clamping cylinder to drive the rotation of the pressure plate.

[0014] Optionally, the clamping cylinder is located outside the two axial clamping blocks.

[0015] Optionally, the clamping cylinder is hinged to the upper part of the axial clamping block.

[0016] Optionally, the upper part of the support block is provided with a groove that matches the outer diameter of the drill rod.

[0017] Optionally, the support block is provided in at least two.

[0018] The beneficial effects of this utility model are as follows:

[0019] (1) Facilitates drill pipe loading and unloading: When the transferor is in the state of waiting to load or unload drill pipes (other clamping mechanisms have already clamped the drill pipes), the clamping cylinder drives the pressure plate to rotate and open upwards, while the sliding cylinder drives the slider to move outwards, expanding the internal space of the transferor. This design makes the loading and unloading of drill pipes more convenient, reduces obstacles in the loading and unloading process, and improves work efficiency.

[0020] (2) Enhanced drill rod stability: When the drill rod is placed in the transfer device and the transfer device needs to rotate or move, the clamping cylinder drives the pressure plate to clamp the drill rod, and the sliding cylinder drives the slider to move towards the center. By clamping the drill rod at both ends with the slider and pressing it at the top with the pressure plate, the drill rod is fixed from multiple directions, which greatly enhances the stability of the drill rod during the transfer process. This effectively avoids problems caused by shaking, deviation, or even falling of the drill rod during the transfer process, ensuring the safety of the operation and the accuracy and quality of the drilling.

[0021] (3) Adaptability to steep inclination conditions: Currently, the transfer device lacks a vertical drill rod fixing mechanism, which prevents it from performing steep inclination movements, thus limiting the drilling inclination range of the automatic drilling rig. However, this transfer device adopts the aforementioned fixing method, which ensures the stability of the drill rod under steep inclination conditions, preventing the drill rod from falling off during inclination adjustment. This expands the application range of the automatic drilling rig, enabling it to adapt to more working conditions requiring steep inclination drilling, such as gas extraction under complex geological conditions and deep groundwater exploration, fully leveraging the automation and high efficiency advantages of the automatic drilling rig.

[0031] Please see Figures 1-2 It is a transfer device for fixing drill rods in a vertical direction, including a base plate 801, a support block 802, a pressure plate 803, a clamping cylinder 804, an axial clamping block, and a sliding cylinder 806.

[0032] The base plate 801 is the main load-bearing and connecting component on the transfer device, providing the mounting foundation for all parts of the transfer device. Components such as the support block 802, axial clamping block, and sliding cylinder 806 are directly or indirectly mounted on the base plate 801, ensuring the integrity and stability of the transfer device structure and enabling all components to work together to complete the transfer and fixing of the drill pipe.

[0033] At least two support blocks 802 are disposed on the base plate 801. The upper part of the support block 802 is provided with a groove matching the outer diameter of the drill rod for supporting the drill rod. In some embodiments of this utility model, two support blocks 802 are preferred. When the drill rod is placed into the transfer device, the drill rod can be stably placed in the groove of the support block 802. The support block 802 bears the main weight of the drill rod, providing reliable support for the drill rod and ensuring that the drill rod will not sink or shake due to its own weight during the transfer process.

[0034] Axial clamping blocks are disposed on the base plate 801 and located on both sides of the support block 802. The axial clamping blocks clamp and fix the drill rod axially. The axial clamping blocks include at least one slider 805 slidably disposed on the base plate 801. In some embodiments of the present invention, one of the axial clamping blocks on both sides of the support block 802 is a fixed block and the other is a slider 805. By sliding the slider 805 on one side on the base plate 801, the internal space can be expanded when the drill rod is placed or removed, or the drill rod can be clamped onto the fixed block on the other side. In other embodiments of the present invention, both axial clamping blocks are sliders 805.

[0035] A pressure plate 803 and a pressure cylinder 804 are hinged to the upper part of the axial clamping block. The pressure plate 803 is located above the support block 802 and is rotatably connected to the upper part of the axial clamping block. The pressure cylinder 804 is located on the outside of the two axial clamping blocks. The pressure cylinder 804 drives the pressure plate 803 and is the power source for rotating the pressure plate 803. Through the extension and retraction of the pressure cylinder 804, power can be transmitted to the pressure plate 803, causing the pressure plate 803 to rotate along a predetermined trajectory, realizing the action of clamping or releasing the drill rod until the drill rod is clamped on the support block 802. The pressure plate 803 applies pressure to the drill rod from the top, further restricting the movement of the drill rod in the vertical and horizontal directions, enhancing the stability of the drill rod fixation, and preventing the drill rod from falling off during transportation. The precise control of the clamping cylinder 804 ensures that the pressure plate 803 applies appropriate pressure to the drill rod, preventing the drill rod from being unable to be effectively fixed due to insufficient pressure, or from being damaged due to excessive pressure.

[0036] A sliding cylinder 806 is provided at the bottom of the base plate 801. The sliding cylinder 806 is connected to the slider 805 and is the power device that drives the slider 805 to slide along the length of the base plate 801. Driving the slider 805 to slide towards the center along the length of the base plate 801 causes the slider 805 to clamp the drill rod, restricting the axial movement of the drill rod. Together with the support block 802 and the pressure plate 803, it forms a multi-directional fixation of the drill rod. The stable operation of the sliding cylinder 806 can accurately control the position and moving speed of the slider 805, ensuring the smooth loading, unloading and fixing of the drill rod, and guaranteeing the stability of the drill rod during transportation.

[0037] When the transfer device is in the state of waiting to load or remove drill rods (other clamping mechanisms have already clamped the drill rods), the clamping cylinder 804 drives the pressure plate 803, which rotates upward to open. The sliding cylinder 806 drives the slider 805 to move to both sides, expanding the internal space to facilitate the loading or removal of drill rods. After the drill rods are loaded or removed, the clamping cylinder 804 drives the pressure plate 803 to rotate back to the clamping position.

[0038] When the drill rod is placed into the transfer device, and the transfer device needs to be rotated or moved, the clamping cylinder 804 drives the pressure plate 803 to clamp the drill rod, and the sliding cylinder 806 drives the slider 805 to move towards the center to keep the internal drill rod stable and prevent it from falling off.

[0039] This utility model adds pressure plates 803, clamping cylinders 804, sliders 805, and sliding cylinders 806 to both ends of the support block 802, and uses a combination of clamping at both ends and pressing at the top to fix the drill rod during transportation, thereby preventing the drill rod from falling off during tilt adjustment.

[0040] When the transferor is in a state of waiting to load or unload drill pipes (while other clamping mechanisms have already secured the drill pipes), the clamping cylinder 804 drives the pressure plate 803 to rotate and open upwards, while the sliding cylinder 806 drives the slider 805 to move outwards, expanding the internal space of the transferor. This design makes loading and unloading drill pipes more convenient, reduces obstacles during loading and unloading, and improves work efficiency.

[0041] When the drill rod is placed into the transfer device, and the transfer device needs to rotate or move, the clamping cylinder 804 drives the pressure plate 803 to clamp the drill rod, and the sliding cylinder 806 drives the slider 805 to move towards the center. By clamping the drill rod at both ends with the slider 805 and pressing it at the top with the pressure plate 803, the drill rod is fixed from multiple directions, greatly enhancing its stability during transfer. This effectively avoids problems caused by shaking, shifting, or even falling during transfer, ensuring operational safety and drilling accuracy and quality.

[0042] Currently, the transfer device lacks a vertical drill rod fixing mechanism, preventing it from performing large-angle movements and thus limiting the drilling angle range of automatic drilling rigs. However, this transfer device, employing the aforementioned fixing method, ensures the drill rod remains stable under large-angle conditions, preventing it from falling off during angle adjustments. This expands the application range of automatic drilling rigs, enabling them to adapt to more situations requiring large-angle drilling, such as gas extraction under complex geological conditions and deep groundwater exploration, fully leveraging the automation and high efficiency advantages of automatic drilling rigs.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
