Description

Technical Field

[0001] This application belongs to the field of drilling technology for goaf areas, specifically relating to a horizontal directional drilling device for treating goaf areas in small kilns. Background Technology

[0002] A drilling and exploration device for goaf areas in a mine, disclosed in CN118481522A, includes a frame. A sliding plate is slidably connected between the two sides of the inner wall of the frame, and a sleeve is rotatably connected to the bottom of the sliding plate. A connector is fitted onto the inner wall of the sleeve. Installation components are provided on both sides of the sleeve. Each installation component includes a housing fixed to one side of the sleeve, and a first motor is fixedly connected to one side of the inner wall of the housing. When installing the auger drill rod, the connector is aligned with the sleeve, and then the first motor is started, driving the threaded rod to rotate. Under the guidance of a movable block, the locking rod moves into the sleeve until it enters a fixed groove. This allows the connector to be fixed to the sleeve, and conversely, the drill rod can be disassembled. The operation is simple and quick, requiring no special tools for loading and unloading, saving manpower and resources and improving work efficiency. Although the above application has many beneficial effects, it still has the following shortcomings: Since the casters and the base are rigidly connected, and the ground in ore mining sites is generally uneven, this design causes all the vibration force generated when the equipment moves to be directly transmitted to the equipment body. In this process, the motor on the equipment body will inevitably be affected by the vibration. Over time, this may cause the connecting parts between the motor and the equipment to loosen. In addition, continuous vibration will also have an adverse effect on the service life of the motor. Summary of the Invention

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0054] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., 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 invention according to the specific circumstances.

[0055] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0056] See also Figure 1-7 As shown, according to an embodiment of this application, a horizontal directional drilling device for treating goaf areas in small kilns is provided, comprising:

[0057] A base 1, on which a drilling assembly 2 is provided, and a plurality of mounting holes are symmetrically opened in pairs on the base 1;

[0058] The movable component 3 is disposed within the mounting hole and is used to move the base 1.

[0059] A buffer component 4 is disposed between the two moving components 3 and is used to support and buffer the moving components 3.

[0060] Specifically, a drilling assembly 2 is installed on the base 1 for horizontal directional drilling operations in the goaf of the small kiln. Several mounting holes are symmetrically arranged in pairs on the base 1, providing positions for the installation of the moving assembly 3. The moving assembly 3 is used to move the base 1 and the entire drilling device, facilitating equipment transfer on uneven mine surfaces. A buffer assembly 4 is positioned between the pairs of moving assemblies 3, providing support and cushioning. When the equipment moves on rough ground, the moving assembly 3 will be subjected to ground impact forces. The buffer assembly 4 absorbs and mitigates these impact forces, preventing the vibration force from being directly and entirely transmitted to the base 1 and the drilling assembly 2.

[0061] When the moving component 3 encounters a ground protrusion or depression, it will generate upward or downward vibration. The buffer component 4 will offset some of the vibration energy, thereby reducing the vibration force transmitted to the base 1. The drilling component 2 and other components will not be continuously affected by strong vibration, which can effectively reduce the probability of loosening of the connection parts between the motor and the equipment. It also helps to extend the service life of the motor and ensure that the drilling operation can be carried out stably and efficiently.

[0062] There are four mounting holes, which are located at the four corners of the base 1. Therefore, there are also four corresponding moving components 3, which are located at the four corners of the base 1 and can support the smooth movement of the base 1. There are two buffer components 4, which are installed between the two moving components 3 and can provide buffer support for the moving components 3 respectively.

[0063] The moving component 3 includes:

[0064] Mounting block 31, which is slidably disposed within the mounting hole;

[0065] Support base 32, the support base 32 is disposed on the mounting block 31;

[0066] The universal wheel 33 is disposed at the bottom of the mounting block 31.

[0067] Specifically, the moving component 3 includes a mounting block 31, a support base 32, and casters 33. The mounting block 31 is slidably disposed within the mounting hole of the base 1. Vertical grooves are formed on both sides of the mounting hole. Sliding blocks installed on both sides of the mounting block 31 at positions corresponding to the grooves are embedded in the grooves, allowing the mounting block 31 to slide stably along the grooves. The support base 32 is disposed on the mounting block 31 and is used to connect with the buffer component 4. The casters 33 are installed at the bottom of the mounting block 31 and can move the entire drilling device on the ground in the goaf of the mine.

[0068] During equipment movement, when encountering uneven ground, the casters 33 move up and down with the undulations of the ground, thereby driving the mounting block 31 to slide within the groove via the slider. This sliding connection method allows the moving component 3 to better adapt to changes in the ground, reducing the direct impact of ground bumps on the base 1 and drilling component 2.

[0069] During the up-and-down sliding process of the mounting block 31, the up-and-down movement is transmitted to the buffer component 4 through the support seat 32. The buffer component 4 buffers the up-and-down movement, which can reduce the transmission of vibration to a certain extent, improve the stability of the drilling device when it moves, and help protect the drilling component 2.

[0070] See also Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, the buffer component 4 includes:

[0071] A rotating seat 41 is disposed on the base 1, and a shaft 42 is disposed on the rotating seat 41;

[0072] Linkage rod 43, the first end of which is connected to the support base 32, and the second end of which is fixedly connected to the shaft 42. When the mounting block 31 moves up and down, the shaft 42 can be rotated through the linkage rod 43. An elastic element is provided between the linkage rod 43 and the base 1.

[0073] Damping element 44, the damping element 44 is disposed on the base 1;

[0074] A tension rod 45 is connected to the damping element 44;

[0075] The pulling member 46 is located between the shaft 42 and the tension rod 45. When the connecting rod 43 drives the shaft 42 to rotate, the pulling member 46 will simultaneously drive the tension rod 45 to move in the direction of the connecting rod 43. At this time, the damping member 44 generates a damping effect.

[0076] Specifically, the buffer assembly 4 includes a rotating seat 41, a shaft 42, a connecting rod 43, an elastic element, a damping element 44, a tension rod 45, and a pulling element 46. The rotating seat 41 is fixed on the base 1, and the shaft 42 is mounted on the rotating seat 41 and can rotate flexibly around the rotating seat 41. The first end of the connecting rod 43 is connected to the support seat 32, and the second end is fixed on the shaft 42. When the elastic element between the connecting rod 43 and the base 1 is in its natural state, it can provide initial support for the connecting rod 43. When the mounting block 31 moves up and down with the universal wheel 33, the support seat 32 will drive the connecting rod 43 to move synchronously, and the connecting rod 43 will in turn drive the shaft 42 to rotate on the rotating seat 41.

[0077] A damping element 44 is mounted on the base 1. A tension rod 45 is connected to the damping element 44, and a pulling element 46 is connected between the shaft 42 and the tension rod 45. When the shaft 42 rotates under the drive of the connecting rod 43, the shaft 42 will rotate, and the pulling element 46 will pull the tension rod 45 to move in the direction of the connecting rod 43. At this time, the damping element 44 will generate a damping force, which will hinder the movement of the tension rod 45.

[0078] When the equipment encounters bumps during movement, the upward movement of the mounting block 31 causes the connecting rod 43 to rotate the shaft 42, stretching the elastic element and generating a reverse elastic force. At the same time, the pulling element 46 pulls the tension rod 45, and the damping effect of the damping element 44 slows down this process, achieving buffering. On a flat surface, the elastic element resets, causing the mounting block 31 to move downward and return to its initial position.

[0079] Among them, the elastic element is a spring, and there are multiple springs.

[0080] See also Figure 5 As shown, the damping element 44 includes:

[0081] A first powerful magnet 441 is disposed on the base 1;

[0082] The second strong magnet 442 is slidably disposed on the base 1. The tension rod 45 is connected to the second strong magnet 442. The opposite ends of the second strong magnet 442 and the first strong magnet 441 are magnetically repelled.

[0083] Specifically, the damping element 44 includes a first strong magnet 441 and a second strong magnet 442. The first strong magnet 441 is fixedly mounted on the base 1 and its position remains unchanged; the second strong magnet 442 is slidably mounted on the base 1 and can move along a preset direction of the base 1. One end of the pull rod 45 is connected to the second strong magnet 442 and can drive the second strong magnet 442 to move synchronously.

[0084] In this configuration, the second strong magnet 442 and the first strong magnet 441 have the same magnetism at opposite ends, meaning they repel each other. When the pull rod 45 moves towards the connecting rod 43 under the action of the pull member 46, it pulls the second strong magnet 442 to slide closer to the first strong magnet 441. At this time, the repulsive force between the second strong magnet 442 and the first strong magnet 441 increases as the distance decreases, forming a damping force that hinders the movement of the second strong magnet 442.

[0085] When the equipment encounters bumps during movement, as the mounting block 31 moves upward, the pulling member 46 drives the tension rod 45 to move. The second strong magnet 442 then moves closer to the first strong magnet 441, increasing the repulsive force. The damping force is transmitted to the shaft 42 and the connecting rod 43 through the tension rod 45 and the pulling member 46, slowing down the upward movement speed of the mounting block 31 and achieving smooth buffering.

[0086] The base 1 has a fixing groove, the first strong magnet 441 is fixedly installed in the fixing groove, and the second strong magnet 442 is slidably installed in the other end of the fixing groove.

[0087] See also Figure 2 , Figure 3 and Figure 5 As shown, the pulling member 46 includes:

[0088] A take-up roller 461 is connected to the shaft 42;

[0089] A pull belt 462 is disposed between the take-up roller 461 and the tension rod 45.

[0090] Specifically, the pulling component 46 includes a take-up roller 461 and a pull belt 462, used to convert the rotation of the shaft 42 into a pulling force on the tension rod 45. The take-up roller 461 is fixedly connected to the shaft 42 and rotates synchronously with the shaft 42. One end of the pull belt 462 is wound around the take-up roller 461, and the other end is connected to the tension rod 45. When the connecting rod 43 drives the shaft 42 to rotate, the take-up roller 461 will rotate accordingly, thereby winding up the pull belt 462. When the mounting block 31 moves upward, the shaft 42 rotates to one side, and the take-up roller 461 rotates synchronously and winds up the pull belt 462. After the pull belt 462 is tightened, it will pull the tension rod 45 to move towards the connecting rod 43, thereby driving the second strong magnet 442 to approach the first strong magnet 441, causing the damping component 44 to produce a damping effect.

[0091] The pull belt 462 is made of a high-strength and flexible material, which ensures that it is not easy to break during winding and unwinding. It can also be closely attached to the take-up roller 461. The size of the take-up roller 461 is matched with the width of the pull belt 462, which allows the pull belt 462 to be evenly wound on it, further improving the transmission efficiency.

[0092] The buffer assembly 4 also includes an adjusting member 47, which is disposed between the tension rods 45 and is used to adjust the position between the two tension rods 45.

[0093] See also Figure 5 , Figure 6 As shown, the adjusting member 47 includes:

[0094] Fixing plate 471, the fixing plate 471 is disposed on the base 1;

[0095] An adjusting tube 472 is rotatably mounted on the fixed plate 471.

[0096] An extension rod 473 is provided, the first end of which is connected to the corresponding tension rod 45, and the second end of which is disposed opposite to the adjusting tube 472. A guide hole is provided on the extension rod 473.

[0097] A limiting rod 474 passes through the guide hole and is connected to the base 1;

[0098] When the adjusting tube 472 is rotated, the extension rod 473 can be driven to move in opposite directions or in the same direction within the adjusting tube 472.

[0099] Specifically, the buffer assembly 4 includes an adjusting component 47, which is disposed between two tension rods 45 to adjust the relative position of the two tension rods 45, thereby adapting to different buffering requirements. The adjusting component 47 includes a fixed plate 471, an adjusting tube 472, an extension rod 473, and a limiting rod 474. The fixed plate 471 is fixedly mounted on the base 1, providing stable support for the adjusting tube 472. The adjusting tube 472 is rotatably mounted on the fixed plate 471 and can rotate freely around its own axis. It has a threaded structure inside that matches the extension rod 473. The first end of the extension rod 473 is fixedly connected to the corresponding tension rod 45, and the second end extends into the adjusting tube 472. The extension rod 473 has a guide hole extending along its length. The limiting rod 474 passes through the guide holes of the two extension rods 473 and is fixed on the base 1, guiding and limiting the movement of the extension rod 473 to prevent it from rotating synchronously with the adjusting tube 472.

[0100] When it is necessary to adjust the position between the two tension rods 45, the adjusting tube 472 is rotated. Since the adjusting tube 472 and the extension rod 473 are connected by threads, and the extension rod 473 cannot rotate under the constraint of the limiting rod 474, the rotational motion of the adjusting tube 472 is converted into the linear motion of the extension rod 473. If the adjusting tube 472 rotates in the forward direction, the two extension rods 473 will move towards each other within the adjusting tube 472, causing the corresponding tension rods 45 to move closer to each other; if the adjusting tube 472 rotates in the reverse direction, the extension rods 473 will move in the reverse direction, causing the two tension rods 45 to move away from each other.

[0101] When the ground is bumpy, the initial distance between the two tension rods 45 can be increased by adjusting the adjustment component 47, so that the initial repulsive force of the damping component 44 is more suitable for violent vibration. When the ground is relatively flat, the distance can be reduced to reduce unnecessary damping consumption and improve movement flexibility.

[0102] An adjustment plate 475 is provided on the adjustment tube 472, and an adjustment groove is provided on the outer circumference of the adjustment plate 475.

[0103] Specifically, an adjusting disc 475 is provided on the adjusting tube 472. Several adjusting grooves are evenly distributed on the outer circumference of the adjusting disc 475, providing convenient operating points for rotating the adjusting tube 472. The adjusting disc 475 is coaxially and fixedly connected to the adjusting tube 472, and its diameter is larger than that of the adjusting tube 472. When the operator needs to adjust the position of the two tension rods 45, they can rotate the adjusting tube 472 by holding the adjusting disc 475 and applying rotational force. Compared to directly rotating the adjusting tube 472, the adjusting disc 475 increases the lever arm, making the rotation operation more effortless. This is especially beneficial when the adjusting tube 472 and the extension rod 473 are difficult to rotate due to a tight threaded fit, effectively reducing the difficulty of operation.

[0104] See also Figure 5 , Figure 6 As shown, the adjusting tube 472 and the extension rod 473 are threadedly connected. The adjusting tube 472 has reverse threads inside and on both sides of the adjusting disc 475. The extension rod 473 is located on both sides of the adjusting disc 475.

[0105] Specifically, the adjusting tube 472 and the extension rod 473 are connected by threads, and the adjusting tube 472 has reverse threads on both sides of the adjusting plate 475. The extension rods 473 on both sides are respectively engaged with the corresponding reverse threads, so that when the adjusting tube 472 is rotated, the extension rods 473 can move in opposite directions. With the adjusting plate 475 as the boundary, the thread direction of the adjusting tube 472 is clockwise on one side and counterclockwise on the other side. When the operator rotates the adjusting tube 472 through the adjusting plate 475, since the extension rods 473 on both sides are engaged with threads of different directions, and the extension rods 473 cannot rotate with the adjusting tube 472 under the constraint of the limiting rod 474, they can only move axially. Therefore, the extension rods 473 on both sides will move in opposite directions, so as to adjust the position of the two tension rods 45, and thus adjust the damping force of the damping element 44 according to the usage requirements.

[0106] See also Figure 4 As shown, the support base 32 includes:

[0107] A support frame 321 is provided with a top rod 322. A drive hole is provided on the first end of the connecting rod 43, and the top rod 322 is located in the drive hole.

[0108] Specifically, the support frame 321 is fixedly mounted on the mounting block 31 and moves up and down synchronously with the mounting block 31. A top rod 322 is mounted on its top. The first end of the connecting rod 43 has an elongated drive hole so that the top rod 322 can move within the drive hole during the up and down movement of the mounting block 31.

[0109] When the mounting block 31 moves up and down due to ground vibrations, the support frame 321 drives the push rod 322 to move synchronously. The push rod 322 moves within the drive hole, thereby pushing or pulling the connecting rod 43, causing the connecting rod 43 to rotate around the shaft 42. For example, when the mounting block 31 moves upward, the push rod 322 pushes the first end of the connecting rod 43 upward, causing the connecting rod 43 to rotate upward around the shaft 42, thereby driving the shaft 42 to rotate and triggering the damping and elastic buffering effect of the buffer assembly 4; when the mounting block 31 moves downward, the push rod 322 moves downward accordingly, the connecting rod 43 rotates downward under the action of the elastic element, the shaft 42 rotates in the opposite direction, and the buffer assembly 4 resets, so that the up and down movement of the moving assembly 3 can be smoothly converted into the rotation of the connecting rod 43, ensuring that the buffer assembly 4 responds in a timely manner and plays a buffering role.

[0110] See also Figure 7 As shown, the drilling assembly 2 includes:

[0111] Mounting box 21, a movable plate 22 is slidably disposed inside the mounting box 21, and sliding grooves are provided on both sides of the mounting box 21. Sliding blocks matching the sliding grooves are provided on both sides of the movable plate 22.

[0112] The first lead screw 23 is disposed inside the mounting box 21 and is threadedly connected to the movable plate 22;

[0113] The first drive motor 24 is mounted on the mounting box 21 and connected to the first lead screw 23;

[0115] The second drive motor 26 is mounted on the movable plate 22, and its output end is connected to the drill rod 25.

[0116] Specifically, the drilling assembly 2 includes a mounting box 21, a movable plate 22, a first lead screw 23, a first drive motor 24, a drill rod 25, and a second drive motor 26. The mounting box 21 is fixed to the base 1, and its interior has grooves on both sides. The sliders on both sides of the movable plate 22 are embedded in the grooves, allowing the movable plate 22 to slide stably horizontally along the grooves. The first lead screw 23 is horizontally disposed inside the mounting box 21 and threadedly connected to the movable plate 22. The first drive motor 24 is mounted on the mounting box 21, and its output end is connected to the first lead screw 23, which can drive the first lead screw 23 to rotate. The first end of the drill rod 25 is connected to the movable plate 22, and the second end extends out through the mounting box 21 to the outside, for contacting and drilling into the rock strata of the goaf. The second drive motor 26 is fixed to the movable plate 22, and its output end is connected to the drill rod 25, which can drive the drill rod 25 to rotate at high speed.

[0117] During drilling operations, the first drive motor 24 starts, driving the first lead screw 23 to rotate. Since the moving plate 22 is threadedly connected to the first lead screw 23 and cannot rotate due to the limitations imposed by the sliding groove and slider, the rotational motion of the first lead screw 23 is converted into the horizontal movement of the moving plate 22, pushing the drill rod 25 towards the goaf area. Simultaneously, the second drive motor 26 starts, driving the drill rod 25 to rotate at high speed. The rotating drill rod 25, pushed by the moving plate 22, continuously penetrates deeper into the rock strata to complete the drilling. If the position of the drill rod 25 needs to be adjusted, the first drive motor 24 rotates in the opposite direction, driving the first lead screw 23 to rotate in the opposite direction. The moving plate 22 then drives the drill rod 25 to move in the opposite direction, achieving the retraction of the drill rod 25. The cooperation of the sliding groove and slider ensures the stability of the moving plate 22 during movement, preventing the drill rod 25 from tilting during movement and ensuring the accuracy of the drilling direction. This ensures the safety and reliability of the drilling process and can better adapt to the complex drilling environment of small-scale goaf areas.
