Description
Technical Field
[0001] This utility model belongs to the technical field of coal mining equipment, specifically relating to a mine pressure relief drilling rig. Background Technology
[0002] In the mining of coal and other mineral resources, in order to effectively avoid risks and ensure operational safety, it is necessary to decompress high-stress coal and rock masses before core mining processes such as tunneling and longwall mining. Among these methods, borehole decompression is one of the most widely used decompression techniques due to its relatively simple operation and direct and controllable decompression effect. By drilling holes at specific depths and angles into the coal and rock mass, the stress accumulated inside the coal and rock mass can be released, reducing the probability of disasters.
[0003] Currently, taking the patent with publication number CN112196512A as an example, the drilling and pressure relief device consists of a machine frame, a drilling system, and an angle adjustment system. The machine frame serves as the foundation for the entire device, moving within the underground roadway to provide installation and support for each component. The drilling system includes a feed mechanism, a drive motor, and a drill bit. The drive motor provides high-speed rotational power to the drill bit, processing the coal and rock mass through cutting or impact crushing. The feed mechanism, using a screw drive structure, controls the drill bit to steadily advance along the drilling direction, gradually completing the drilling operation. The angle adjustment system is located between the machine frame and the drilling system, employing a hinged connection and hydraulic cylinder drive to adjust the angle of the drilling system to adapt to different operational needs.
[0004] However, in practical applications, the drill bit can only move forward or backward along the preset drilling direction and cannot independently make fine adjustments to its lateral position. When multiple laterally distributed boreholes need to be drilled on the same working face and at the same height, the operator needs to control the entire machine support to move laterally to adjust the lateral position of the drill bit. However, the underground roadway space is narrow, and the machine support is usually large and heavy. During the lateral movement, not only is it necessary to adjust the support status of the device multiple times, but also to manually assist in calibrating the position. The entire adjustment process is time-consuming, cumbersome, and laborious, seriously affecting work efficiency. Utility Model Content
[0005] This invention addresses the problem that the lateral displacement of the drill bit requires moving the entire vehicle body, which is time-consuming and labor-intensive. It provides a mining pressure relief drilling rig that can directly achieve the lateral displacement of the drill bit without moving the entire vehicle body, thus significantly saving operation time and labor costs.
[0006] To solve the above problems, the technical solution adopted by this utility model is as follows: a mining pressure relief drilling rig includes a vehicle body, a lifting assembly on the top of the vehicle body, a mounting frame above the lifting assembly, and an angle adjustment assembly between the mounting frame and the lifting assembly to adjust the tilt angle of the mounting frame; a transverse frame is provided above the mounting frame, and a drilling assembly and a propulsion assembly are provided on the transverse frame. The drilling assembly can drill holes in the rock wall, and the propulsion assembly can push the drilling assembly to move along the drilling direction; a transverse screw is internally threaded onto the transverse frame, the axis of the transverse screw is perpendicular to the moving direction of the drilling assembly, one end of the transverse screw is rotatably connected to the mounting frame, and the other end is fixedly connected to the output shaft of the transverse motor, which is fixed on the mounting frame; a second guide rod is provided on both sides of the transverse screw, the second guide rod is arranged parallel to the transverse screw, the second guide rod passes through the transverse frame and slides with the transverse frame, and both ends of the second guide rod pass through the transverse frame and are fixedly connected to the mounting frame.
[0007] In this technical solution, the lifting component can adjust the height of the drilling component, and the angle adjustment component can flexibly adjust the tilt angle of the drilling component. When the traverse motor drives the traverse screw to rotate, it can drive the traverse frame and the drilling component on the frame to move laterally along the traverse screw. At the same time, the second guide rod provides stable guidance for the traverse frame's lateral movement, preventing deviation. The drilling component is used to perform drilling operations on the rock wall, and the propulsion component can push the drilling component to drill steadily along the drilling direction, ensuring drilling depth and efficiency. Therefore, before drilling operations, this device can not only accurately adjust the height and tilt angle of the drilling component, but also flexibly adjust its lateral position without moving the vehicle body, eliminating the need for frequent movement of the entire equipment and effectively saving significant operating time and labor costs.
[0008] Furthermore, the lifting assembly includes a base plate fixed to the top of the vehicle body. A vertically arranged lifting cylinder is mounted on the base plate, with its cylinder barrel fixedly connected to the upper surface of the base plate. A lifting frame is fixed to the end of the telescopic rod of the lifting cylinder. A first guide rod, vertically arranged and with its lower end fixedly connected to the upper surface of the base plate, is mounted on the lifting frame. The vertically arranged lifting cylinder directly drives the lifting frame to move vertically, providing stable driving force to support the weight of the lifting frame and the upper assembly. It also allows for precise adjustment of the drilling assembly height through precise stroke control of the lifting cylinder. The first guide rod strictly limits the movement trajectory of the lifting frame, preventing lateral deviation or tilting due to uneven force on the lifting cylinder or vibrations underground during lifting. This ensures the lifting frame always moves smoothly vertically, thus guaranteeing that the upper drilling assembly maintains its preset operating posture after height adjustment.
[0009] Furthermore, the angle adjustment assembly includes a connecting frame and an angle adjustment electric cylinder. The bottom of the connecting frame is fixedly connected to the top of the lifting frame, and the top of the connecting frame is rotatably connected to the bottom of the mounting frame. The cylinder of the angle adjustment electric cylinder is rotatably connected to the top of the lifting frame, and the end of the telescopic rod of the angle adjustment electric cylinder is rotatably connected to the bottom of the mounting frame. The fixed connection between the bottom of the connecting frame and the top of the lifting frame, and the rotatable connection between the top of the connecting frame and the bottom of the mounting frame, provides a stable fulcrum for the mounting frame. At the same time, the rotatable connection between the cylinder of the angle adjustment electric cylinder and the top of the lifting frame, and the rotatable connection between the end of the telescopic rod and the bottom of the mounting frame, allows the rotating structures at both ends to flexibly adapt to the rotation trajectory of the mounting frame when the telescopic rod of the angle adjustment electric cylinder extends or retracts. This avoids movement jamming caused by rigid connections, allowing the mounting frame to rotate smoothly with the top of the connecting frame as the fulcrum. This, in turn, drives the upper transverse frame and drilling assembly to achieve multi-angle adjustments, accurately matching the drilling angle requirements of different coal seam occurrence angles or decompression processes. Its adaptability is far superior to fixed-angle or single-degree-of-freedom adjustment structures.
[0010] Furthermore, the propulsion assembly includes a propulsion frame located above the transverse frame. A propulsion screw is internally threaded onto the propulsion frame, with its axial direction parallel to the movement direction of the drilling assembly. One end of the propulsion screw is rotatably connected to the transverse frame, and the other end is fixedly connected to the output shaft of the propulsion motor, which is fixedly mounted on the transverse frame. Third guide rods are provided on both sides of the propulsion screw, parallel to it. These guide rods pass through the propulsion frame and slide within it, with both ends penetrating the frame and fixedly connected to the transverse frame. The propulsion motor is fixed to the transverse frame, its output shaft directly fixedly connected to the propulsion screw, while the other end of the propulsion screw is rotatably connected to the transverse frame. This one-end-drive-one-end-support design ensures uniform rotation of the propulsion screw. The propulsion frame is threadedly connected to the propulsion screw, allowing the screw to rotate smoothly along the drilling direction. This not only enables precise adjustment of the feed rate by controlling the propulsion motor's speed but also allows for precise control of the propulsion frame's movement distance by counting the propulsion motor's stroke, thus achieving precise control of the drilling depth. The third guide rods on both sides of the push screw are set parallel to the push screw and are inserted into the push frame to form a sliding fit. The third guide rods can strictly limit the movement trajectory of the push frame, and prevent the push frame from being slightly bent or tilted laterally due to uneven force on the push screw, such as downhole vibration. This ensures that the push frame always moves in a straight line along the drilling direction, thereby ensuring that the drill bit is always aligned with the preset drilling path and preventing the drilling tilt from affecting the pressure relief effect.
[0011] Furthermore, the drilling assembly includes a drill body, which is fixedly installed within the feed frame and positioned above the feed screw. A drill bit is mounted on the drill body, with its axial direction parallel to that of the feed screw. The fixed installation of the drill body within the feed frame ensures a stable relative position between the drill body and the feed frame. During drilling operations, the high-speed rotation of the drill body generates continuous vibration. The fixed installation prevents displacement or shaking due to vibration, ensuring the drill bit maintains its preset operating posture and providing fundamental support for drilling accuracy. Simultaneously, the feed frame provides encircling protection for the fixed drill body, reducing the direct impact of dust and rock debris on the drill body during downhole operations, lowering the risk of component wear, and extending equipment lifespan.
[0012] Furthermore, a first distance sensor is installed on the side of the vehicle body, which can monitor the distance between the vehicle body and the rock wall. Underground tunnels are narrow and the rock walls may have irregular shapes, with protruding rocks or recessed areas. If the distance is not properly controlled during the drilling rig's movement, it is prone to collision with the rock wall. The first distance sensor can provide real-time distance data, and can issue a timely warning when the vehicle body approaches the rock wall to a safe threshold, reminding the operator to adjust the direction of movement or stop moving, thus avoiding damage to the vehicle body structure or rock wall collapse, reducing equipment maintenance costs and tunnel safety hazards.
[0013] Furthermore, a second distance sensor is installed on the mounting frame, which can monitor the movement distance of the traverse frame. The second distance sensor can provide real-time feedback on the movement distance of the traverse frame, and the operator or control system can use this data to precisely control the start and stop of the traverse motor, so that the traverse frame moves exactly to the preset transverse drilling position.
[0014] Furthermore, a third distance sensor is installed on the propulsion frame, which can monitor the movement distance of the propulsion frame. The third distance sensor can provide real-time feedback on the movement data of the propulsion frame. Based on this data, operators or the control system can accurately determine whether the drilling depth has reached the preset standard. Once the depth reaches the standard, the propulsion motor can be stopped in time to avoid problems of insufficient or excessive drilling, ensuring that the depth of each pressure relief hole meets the process requirements, allowing for uniform stress release in the coal and rock mass, and improving the stability of the pressure relief effect.
[0015] Furthermore, the propulsion frame is equipped with a height sensor, an inclination sensor, and a monitoring camera. The height sensor monitors the height of the propulsion frame, the inclination sensor monitors its tilt angle, and the monitoring camera monitors the drilling process of the drilling assembly. The height sensor transmits the propulsion frame's height data to the control system in real time, allowing operators to determine the propulsion frame's height without manual measurement. The inclination sensor captures changes in the propulsion frame's tilt in real time; even if downhole vibration causes a slight shift in the angle adjustment assembly, it can promptly report the deviation data, assisting operators or the control system in fine-tuning the angle adjustment cylinder to calibrate the propulsion frame's tilt angle to the preset value. The monitoring camera clearly captures details such as the rotation of the drill bit, the smoothness of slag removal, and whether the drill bit shows signs of wear or breakage, transmitting the images back to the control terminal in real time.
[0016] Furthermore, a rock wall scanner is installed at the top of the lifting frame, which can scan and record the shape of the rock wall. The rock wall scanner can generate three-dimensional morphological data of the rock wall through scanning, clearly showing the protrusions, depressions, and fissures of the rock wall. Based on this data, operators or control systems can avoid potential hazard areas and select the best drilling points with intact rock layers and concentrated stress. At the same time, combined with the tilt trend of the rock wall, the drilling angle can be adjusted to ensure that the drilling can effectively penetrate high-stress areas, improve the pressure relief effect, and avoid operational failures or equipment damage caused by blindly selecting drilling positions.
[0017] As can be seen from the above embodiments, the beneficial effects of this utility model are as follows: In this technical solution, the lifting component can adjust the height of the drilling component, while the angle adjustment component can flexibly control its tilt angle. When the lateral movement motor drives the lateral movement screw to rotate, it can drive the lateral movement frame and the drilling component on it to move laterally along the lateral movement screw. At the same time, the second guide rod provides stable guidance for the lateral movement, preventing deviation. The drilling component is responsible for carrying out drilling operations on the rock wall, while the propulsion component pushes the drilling component to drill steadily along the drilling direction, ensuring drilling depth and work efficiency. Therefore, before drilling operations, this device can not only accurately adjust the height and tilt angle of the drilling component, but also flexibly adjust the lateral position without moving the vehicle body, avoiding frequent movement of the entire equipment, thereby significantly saving operation time and labor costs.

[0024] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.
[0025] A type of mining pressure relief drilling rig, such as Figure 1-2 As shown, the system includes a vehicle body 1, which can be remotely controlled. A first distance sensor 3 is mounted on its side. The first distance sensor 3 is a laser distance sensor, which measures the distance between the vehicle body 1 and the rock wall by emitting a laser and calculating the time difference, ensuring that the vehicle body 1 does not collide with the rock wall when moving, such as the KKIT CD-100A model. A vertically arranged support cylinder 10 is fixedly installed at the corner of the vehicle body 1, with the end of the telescopic rod of the support cylinder 10 facing downwards. When the vehicle body 1 reaches the predetermined position, the telescopic rod of the support cylinder 10 extends, which can lift the vehicle body 1 and support it stably on the ground. A drilling mechanism 2 is installed on the vehicle body 1. The drilling mechanism 2 is used to drill holes in the rock wall to relieve pressure, and the drilling position can be adjusted in both vertical and horizontal directions.
[0026] The drilling mechanism 2 includes a lifting assembly 21, an angle adjustment assembly 22, a lateral movement assembly 23, a propulsion assembly 24, and a drilling assembly 25. The lifting assembly 21 can control the drilling assembly 25 to move up and down in the vertical direction, the angle adjustment assembly 22 can control the tilt angle of the drilling assembly 25, the lateral movement assembly 23 can control the lateral movement of the drilling assembly 25, and the propulsion assembly 24 can control the drilling distance of the drilling assembly 25. The drilling assembly 25 can drill holes in the rock wall.
[0027] The lifting assembly 21 includes a base plate 211, which is welded and fixed to the top of the vehicle body 1. A vertically arranged lifting cylinder 212 is mounted on the base plate 211. The cylinder of the lifting cylinder 212 is bolted to the upper surface of the base plate 211, and a horizontally arranged lifting frame 213 is bolted to the end of its telescopic rod. A first guide rod 2111 passes through the lifting frame 213, allowing the lifting frame 213 to slide along the first guide rod 2111. The first guide rod 2111 is vertically arranged, with its lower end welded to the upper surface of the base plate 211 and its upper end welded with a stop to prevent the lifting frame 213 from sliding out. In this embodiment, there are four first guide rods 2111, arranged around the lifting cylinder 212. Furthermore, a rock wall scanner 9 is mounted on the top of the lifting frame 213. The rock wall scanner 9 is an existing device capable of scanning and recording the shape of rock walls, such as the Oslai Intelligent YHS12-RM+ model.
[0028] like Figure 3-4 As shown, the angle adjustment assembly 22 includes an angle adjustment cylinder 221 and a connecting frame 2131. The cylinder of the angle adjustment cylinder 221 is rotatably connected to the top of the lifting frame 213 via a hinge shaft, and the end of its telescopic rod is also rotatably connected to the bottom of the mounting frame 222 via a hinge shaft. There are two connecting frames 2131, vertically distributed on both sides of the mounting frame 222. Their bottoms are welded to the top of the lifting frame 213, and their tops are rotatably connected to the bottom of the mounting frame 222 via hinge shafts.
[0029] The lateral movement assembly 23 includes a lateral movement frame 233, which is located above the mounting frame 222. The drilling assembly 25 and the propulsion assembly 24 are mounted on the lateral movement frame 233 and move synchronously with it. A lateral movement screw 232 is internally threaded onto the lateral movement frame 233. The axial direction of the lateral movement screw 232 is perpendicular to the moving direction of the drilling assembly 25. One end of the screw 232 is rotatably connected to the mounting frame 222 via a bearing, and the other end is fixedly connected to the output shaft of the lateral movement motor 231 via a coupling. The lateral movement motor 231 is fixed to the mounting frame 222 with bolts. Second guide rods 2221 are provided on both sides of the lateral movement screw 232. The second guide rods 2221 are parallel to the lateral movement screw 232, pass through the lateral movement frame 233 and slide within it, and are welded to the mounting frame 222 after passing through the lateral movement frame 233 at both ends. In addition, a second ranging sensor 4 is installed on the edge of the mounting bracket 222. The second ranging sensor 4 is a laser ranging sensor, and its transmitter is facing the transverse frame 233. It measures the distance between the transverse frame 233 and the edge of the mounting bracket 222 by emitting laser and calculating the time difference, so as to accurately control the displacement distance of the transverse frame 233, such as the Pepperl+Fuchs OMT600-R201-UEP-IO-V31-L model.
[0030] The propulsion assembly 24 includes a propulsion frame 243, which is a hollow rectangular frame located above the transverse frame 233. A threaded hole, not communicating with the cavity, is located below the internal cavity, and a propulsion screw 242 is threadedly connected to the threaded hole. The axial direction of the propulsion screw 242 is parallel to the movement direction of the drilling assembly 25. One end of the screw is rotatably connected to the transverse frame 233 via a bearing, and the other end is fixedly connected to the output shaft of the propulsion motor 241 via a coupling. The propulsion motor 241 is bolted to the transverse frame 233 and is a bidirectional drive motor capable of forward and reverse rotation. Third guide rods 2331 are provided on both sides of the propulsion screw 242. These guide rods 2331 are parallel to the propulsion screw 242, pass through the propulsion frame 243 and slide within it, and are welded to the transverse frame 233 at both ends after passing through the propulsion frame 243. A third ranging sensor 5 is installed on the propulsion frame 243. This third ranging sensor 5 is a laser ranging sensor, with its transmitter facing the propulsion motor 241. It measures the distance between the propulsion motor 241 and the propulsion frame 243 by emitting laser light and calculating the time difference, thereby monitoring the movement distance of the propulsion frame 243. A height sensor 6 is fixedly installed on the outer side of the propulsion frame 243, and an tilt sensor 7 and a monitoring camera 8 are fixedly installed on the top. The height sensor 6, tilt sensor 7, and monitoring camera 8 are all existing devices, specifically the Keyence LK-G507 model, the Shandong Weimengshi Technology SN-3001-DIP-N01 model, and the Guangli Technology KJ1661 mining camera, respectively. These three devices are used to monitor the height of the propulsion frame 243, the tilt angle of the propulsion frame 243, and the drilling status of the drilling assembly 25.
[0031] The drilling assembly 25 includes a punch drill body 251, which is installed inside the internal cavity of the feed frame 243 and fixed with bolts, and is located above the feed screw 242. A punch drill bit 252 is installed on the punch drill body 251. The feed frame 243 has a communication port, through which the punch drill bit 252 extends from the internal cavity of the feed frame 243 to the outside without interfering with the feed frame 243. The axial direction of the punch drill bit 252 is parallel to the axial direction of the feed screw 242, ensuring that the punch drill bit 252 can drill axially.
[0032] The specific operating procedure is as follows: First, the operator drives the vehicle body 1 to the predetermined working position via a remote control terminal. During the movement, the first distance sensor 3 on the side of the vehicle body 1 continuously emits lasers to detect the distance to the surrounding rock walls. The data is transmitted to the remote control terminal in real time, and the operator adjusts the direction and speed of movement accordingly to ensure that the vehicle body 1 always maintains a safe distance from the rock walls until it is precisely stopped at the predetermined position. After the vehicle body 1 is in place, the telescopic rod of the control support cylinder 10 extends, driving the support plate 11 close to the ground and applying support force to lift and secure the vehicle body 1, preventing displacement due to vibration during subsequent operations. Then, the rock wall scanner 9 on the top of the lifting frame 213 is activated to perform a comprehensive scan of the working face rock wall, collect rock wall morphology data, generate a three-dimensional model, and transmit it to the remote control terminal, providing a basis for confirming the drilling location to avoid risky areas such as cracks and loose rock blocks.
[0033] According to the preset drilling parameters, the remote control terminal retrieves the current height of the propulsion frame 243 from the height sensor 6 and the current tilt angle from the tilt sensor 7, and compares them with the preset parameters. If the height does not match, the lifting cylinder 212 is controlled to extend and retract, driving the lifting frame 213 to rise and fall along the first guide rod 2111 until the height sensor 6 data matches the preset height; simultaneously, the angle adjustment cylinder 221 is controlled to extend and retract, driving the mounting frame 222 to rotate around the hinge point with the connecting frame 2131 until the tilt sensor 7 data matches the preset angle, completing the height and angle calibration. After calibration, the transverse motor 231 is started, and its output shaft drives the transverse screw 232 to rotate through the coupling, causing the transverse frame 233 to move laterally along the second guide rod 2221. The second distance sensor 4 at the edge of the mounting frame 222 detects the distance between the transverse frame 233 and the edge of the mounting frame 222 in real time. When the displacement reaches the preset value, the transverse motor 231 stops, and the transverse frame 233 stops precisely at the predetermined transverse position.
[0034] Upon entering the drilling phase, the drilling rig 251 is first started, driving the drill bit 252 to rotate at high speed. Then, the propulsion motor 241 is started, driving the propulsion screw 242 to rotate. The propulsion frame 243 moves along the third guide rod 2331 towards the rock wall, causing the drilling rig 251 and drill bit 252 to synchronously approach the rock wall and begin drilling. During this process, the third distance sensor 5 continuously monitors the distance between the propulsion frame 243 and the propulsion motor 241, calculates the drilling depth, and feeds it back to the remote control terminal. When the depth reaches the preset value, the propulsion motor 241 rotates in the opposite direction, driving the propulsion frame 243 to withdraw the drilling rig 251 and drill bit 252 from the borehole until they are completely disengaged, at which point the machine stops. During drilling, the monitoring camera 8 on top of the propulsion frame 243 continuously captures the drilling status of the drill bit 252, the slag removal situation, and the wear degree of the drill bit, transmitting the images to the terminal in real time. Operators must observe the entire process. If any abnormalities such as stuck drill or slag blockage are found, an emergency stop command must be sent immediately. First, the propulsion motor 241 must be stopped, and then the drilling machine body 251 must be stopped. Operations can only continue after the fault has been eliminated.
[0035] As can be seen from the above embodiments, the beneficial effects of this utility model are as follows: In this specific embodiment, the lifting component can adjust the height of the drilling component, while the angle adjustment component can flexibly control its tilt angle. When the lateral movement motor drives the lateral movement screw to rotate, it can drive the lateral movement frame and the drilling component on it to move laterally along the lateral movement screw. At the same time, the second guide rod provides stable guidance for the lateral movement, preventing deviation. The drilling component is responsible for carrying out drilling operations on the rock wall, while the propulsion component pushes the drilling component to drill steadily along the drilling direction, ensuring drilling depth and work efficiency. Therefore, before drilling operations, this device can not only accurately adjust the height and tilt angle of the drilling component, but also flexibly adjust the lateral position without moving the vehicle body, avoiding frequent movement of the entire equipment, thereby significantly saving operation time and labor costs.
