Description

Technical Field

[0001] This invention relates to the field of support device technology, specifically to an adaptive support device for intelligent hydraulic supports in coal mines. Background Technology

[0002] The intelligent hydraulic support adaptive support device for underground coal mines is a hydraulic support equipment used in underground coal mine working faces. It can automatically adjust the support status through an intelligent system to adapt to complex geological conditions and mining conditions. Its core is to achieve active and precise support of the roadway roof by combining hydraulic drive and intelligent control, so as to ensure mining safety and efficiency.

[0003] Traditional automated control systems for intelligent hydraulic supports in underground coal mines suffer from problems such as low automation and strong reliance on manual operation. For example, in traditional control schemes, the adjustment of the support configuration of the support group is mostly done in a semi-automatic manner, requiring manual judgment of the relative positional relationship between the support and the coal mining machine, and then providing adjustment signals. The control accuracy is low, the support group cannot operate in conjunction with the coal mining machine, and the lack of adjustment support structure at the bottom significantly reduces the stability of the support device. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent hydraulic support adaptive support device for underground coal mines, which has the advantage of adjustable support and solves the problems in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The intelligent hydraulic support adaptive support device for underground coal mines includes a support base plate. An adjusting support assembly for laterally adjusting the support position is provided on the upper end of the support base plate. Linkage sliding plates are fixedly installed on both sides of the upper end of the adjusting support assembly. Side support components are provided on the upper end of the linkage sliding plates. Support mounting plates are provided on the side support components. A controller is fixedly installed on the upper end of the support mounting plates. An adjusting hydraulic rod is fixedly installed on the upper end of the controller. A support frame plate is fixedly installed at the output end of the adjusting hydraulic rod. A telescopic adjustment assembly is provided on the support frame plate. The side support components include a side support vertical plate fixedly installed on the upper end of the linkage sliding plate, an inclined support plate fixedly installed on the side end of the side support vertical plate, an inclined hydraulic push rod fixedly installed on the inclined support plate, and a support inclined plate fixedly connected to the output end of the inclined hydraulic push rod.

[0006] Preferably, the adjusting support assembly includes a protective outer frame plate fixedly installed on the upper part of the support base plate and a bidirectional drive motor fixedly installed at the center of the protective outer frame plate.

[0007] It is worth noting that the protective outer frame plate can provide physical protection for core components such as the bidirectional drive motor and bidirectional threaded rotating rod inside the adjustment support assembly, preventing underground dust and gravel from directly impacting or covering the components and extending their service life; however, it is necessary to ensure that the connection with the support base plate is firm during installation to avoid loosening due to underground vibration.

[0008] Preferably, a bidirectional threaded rotating rod is fixedly installed at the output end of the bidirectional drive motor, and two sets of bidirectional moving sleeves are threadedly connected to the outer side of the bidirectional threaded rotating rod, with the upper end of the bidirectional moving sleeves connected to the lower end of the linkage slide plate.

[0009] It is worth noting that the bidirectional thread design on the surface of the bidirectional threaded rotating rod allows the two sets of bidirectional moving blocks to move synchronously in opposite directions or in the opposite direction when they rotate, ensuring the symmetry and stability of the lateral adjustment and avoiding support imbalance caused by unilateral adjustment; however, it is necessary to ensure the coaxiality of the bidirectional threaded rotating rod during installation to avoid accelerated thread wear or jamming due to installation deviation.

[0010] Preferably, guide sliding grooves are provided on both sides of the protective outer frame plate, and guide cross plates are fixedly connected to both sides of the bidirectional moving sleeve block.

[0011] It is worth noting that: one end of the guide plate is fixed to the bidirectional moving sleeve block, and the other end can slide along the guide sliding groove and the transverse guide rod, which can constrain the movement of the bidirectional moving sleeve block in the horizontal direction, enhance the stability of the bidirectional moving sleeve block when it moves, and prevent it from tilting or shaking; however, it is necessary to ensure that the connection between the guide plate and the bidirectional moving sleeve block is firm to prevent the connection from falling off due to vibration.

[0012] Preferably, the upper end of the protective outer frame plate is provided with two sets of movable grooves, and the upper ends of the support base plate are fixedly connected with side mounting plates on both sides.

[0013] It is worth noting that the side mounting plates are fixed to the upper sides of the support base plate, providing a stable installation foundation for the transverse guide rod and ensuring that the installation position of the transverse guide rod is accurate and firm. However, it is necessary to ensure the perpendicularity and connection between the side mounting plates and the support base plate during installation to avoid the transverse guide rod tilting due to installation deviation.

[0014] Preferably, a transverse guide rod is fixedly connected to the inner side of the side mounting plate, and the transverse guide rod is slidably connected to the guide plate.

[0015] It is worth noting that the transverse guide rod is slidably connected to the guide plate, which can guide the movement of the guide plate from the other side. Together with the guide sliding groove, it forms a double guide structure, which further improves the linearity and stability of the bidirectional moving block. However, it is necessary to keep the surface of the transverse guide rod smooth and apply grease regularly to reduce sliding friction with the guide plate.

[0016] Preferably, the upper end of the linkage slide plate is fixedly connected to a transverse rotating shaft that is rotatably connected to the support slope plate, and the upper end of the support slope plate is connected to a connecting side plate, and the side end of the connecting side plate is connected to the side end of the bracket mounting plate.

[0017] It is worth noting that the connecting side plate uses a shaft connection to connect the support slope plate and the bracket mounting plate, which allows for a certain degree of relative rotation between the two. This ensures that when the tilt angle of the support slope plate is adjusted, the bracket mounting plate can move smoothly accordingly, avoiding excessive stress on the components due to rigid connection. However, it is necessary to lubricate the shaft connection part of the connecting side plate regularly to prevent rust or wear that could lead to inflexible rotation.

[0018] Preferably, the telescopic adjustment assembly includes a control cavity formed inside the support frame plate and a lateral drive hydraulic rod fixedly installed inside the control cavity.

[0019] It is worth noting that: the lateral drive hydraulic rod, as the power source of the telescopic adjustment component, can provide a large lateral driving force to realize the telescopic movement of the first extension support plate and adjust the support length range; however, it is necessary to select a hydraulic rod model that meets the requirements of explosion-proof and pollution-resistant in underground coal mines, ensure the sealing of the hydraulic system, and prevent hydraulic oil leakage from polluting the environment or affecting the driving performance.

[0020] Preferably, a vertical connecting rod is fixedly installed at the output end of the horizontal drive hydraulic rod, a fixed crossbar is fixedly connected to the side end of the vertical connecting rod, an installation connecting block is fixedly connected to the upper end of the fixed crossbar, a telescopic storage groove is opened inside the support frame plate, a first extension support plate that slides inside the telescopic storage groove is fixedly connected to the upper end of the installation connecting block, and a first detection plate is fixedly connected to the side end of the first extension support plate.

[0021] It is worth noting that the first detection plate integrates multiple sensors, which can collect key data such as the pressure and displacement changes of the top plate on the side of the first extended support plate in real time, providing the controller with accurate environmental monitoring data and helping to achieve adaptive adjustment of the support device. The first detection plate is small in size and easy to install, and can move directly synchronously with the first extended support plate to ensure the real-time performance and accuracy of the monitoring data. However, it is necessary to select sensors with waterproof, dustproof and anti-interference performance to ensure stable operation in the harsh underground environment.

[0022] Preferably, both sides of the support frame are provided with side-end expansion components. The side-end expansion components include side hydraulic telescopic rods fixedly installed on both sides of the support frame, linkage side plates fixedly connected to the side ends of the side hydraulic telescopic rods, a second extension support plate fixedly connected to the upper end of the linkage side plate, and a second detection plate fixedly installed on the side end of the second extension support plate.

[0023] It is worth noting that the second detection plate complements the first detection plate in function. It can monitor the top pressure, displacement and surrounding rock deformation at the side of the second extended support plate in real time, providing the controller with comprehensive downhole environmental monitoring data and avoiding untimely support adjustments due to monitoring blind spots. However, it is necessary to clean the dust on the surface of the detection plate regularly to prevent dust from covering the sensors and affecting the monitoring accuracy.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention features a flexible lateral adjustment function for the adjustable support components. The support position can be adjusted in real time according to the width of the underground roadway and the roof support requirements. It can also drive the upper linkage slide plate to move laterally synchronously, thereby adjusting the lateral position of the support components on both sides and the upper support frame. This achieves flexible adaptation of the support range in the horizontal direction, overcoming the limitations of traditional "fixed-position support" devices. The position can be precisely adjusted for the support needs of different areas of the roof, reducing support blind spots. Furthermore, the telescopic adjustment components can flexibly adjust the support length according to the length of the underground roadway or the longitudinal support requirements of the roof, eliminating the need for additional support devices, reducing equipment investment costs, improving the device's adaptability to roadways of different lengths, and reducing support blind spots caused by excessively long roadways.

It meets the ExdI coal mine explosion-proof standard; the controller 6 is fixedly installed with an adjusting hydraulic rod 7, and the output end of the adjusting hydraulic rod 7 is fixedly installed with a support plate 8.

The two-sided support components include a side support vertical plate 401 fixedly installed on the upper end of the linkage slide plate 3, an inclined support plate 402 fixedly installed on the side end of the side support vertical plate 401, an inclined hydraulic push rod 403 fixedly installed on the inclined support plate 402, and a support inclined plate 404 fixedly connected to the output end of the inclined hydraulic push rod 403. The upper end of the linkage slide plate 3 is fixedly connected with a transverse rotating shaft 405 that is rotatably connected to the support inclined plate 404. The upper end of the support inclined plate 404 is axially connected with a connecting side plate 406, and the side end of the connecting side plate 406 is connected to the side end of the bracket mounting plate 5.

[0030] The adjusting support assembly includes a protective outer frame plate 201 fixedly installed on the upper end of the support base plate 1, and a bidirectional drive motor 202 fixedly installed at the center of the protective outer frame plate 201. The bidirectional drive motor 202 is a YBK2-160M-4 mining explosion-proof three-phase asynchronous motor with a rated power of 11kW, a rated speed of 1440r / min, and a protection level of IP54. A bidirectional threaded rotating rod 203 is fixedly installed at the output end of the bidirectional drive motor 202. The bidirectional threaded rotating rod 203 is made of 40CrNiMoA alloy structural steel with a diameter of 50mm, a surface treated with quenching and tempering, a hardness of HRC28-32, and is machined with rolled threads with a thread accuracy of 6g. The bidirectional moving sleeve 204 is made of... Made of ZCuAl10Fe3 aluminum bronze, the inner part has an internal thread that matches the bidirectional threaded rotating rod 203. The outer thread of the bidirectional threaded rotating rod 203 is connected to two sets of bidirectional moving sleeves 204, and the upper end of the bidirectional moving sleeves 204 is connected to the lower end of the linkage slide plate 3. The protective outer frame plate 201 has guide sliding grooves 205 on both sides. The bidirectional moving sleeves 204 are fixedly connected to guide horizontal plates 206 on both sides. The upper end of the protective outer frame plate 201 has two sets of moving grooves 207. The upper end of the support base plate 1 is fixedly connected to the side mounting plates 208 on both sides. The inner side of the side mounting plates 208 is fixedly connected to the transverse guide rods 209, and the transverse guide rods 209 are slidably connected to the guide horizontal plates 206.

[0031] The telescopic adjustment assembly includes a control cavity 901 located inside the support frame plate 8, and a transverse drive hydraulic rod 902 fixedly installed inside the control cavity 901. The transverse drive hydraulic rod 902 is a CG200×400 mining hydraulic rod with a rated thrust of 50kN and a stroke of 400mm. A vertical connecting rod 903 is fixedly installed at the output end of the transverse drive hydraulic rod 902. A fixed crossbar 904 is fixedly connected to the side end of the vertical connecting rod 903. A mounting connecting block 905 is fixedly connected to the upper end of the fixed crossbar 904. A telescopic storage groove 906 is provided inside the support frame plate 8. The upper end of the connecting block 905 is fixedly connected to a first expansion support plate 907 that slides inside the telescopic storage slot 906. The side end of the first expansion support plate 907 is fixedly connected to a first detection plate 908. The first detection plate 908 integrates a PT124G-111 mining pressure sensor with a measurement range of 0-60MPa and an accuracy of 0.5 grade. It also includes a KTC-102 mining displacement sensor with a measurement range of 0-500mm and an accuracy of ±0.5%FS. All sensors have ExdI explosion-proof certification and are suitable for underground working environments of -20℃ to 60℃ and relative humidity of ≤95%.

[0032] During operation, the device is first fixed to the designated position on the underground working face by the support base plate 1. After the controller 6 is initialized, the adjustment support assembly is started to achieve lateral position adjustment: the bidirectional drive motor 202 is powered on and runs, and the output end drives the bidirectional threaded rotating rod 203 to rotate. Since the outer thread of the bidirectional threaded rotating rod 203 is connected to two sets of bidirectional moving sleeves 204, and the guide horizontal plates 206 on both sides of the bidirectional moving sleeves 204 slide along the guide sliding groove 205 of the protective outer frame plate 201 and the lateral guide rod 209 of the side mounting plate 208 respectively, the two sets of bidirectional moving sleeves 204 move laterally in opposite directions along the bidirectional threaded rotating rod 203, thereby driving the linkage slide plate 3 fixed at the upper end to move laterally synchronously until it is adjusted to the support position that matches the width of the roadway, and the bidirectional drive motor 202 stops running. Subsequently, the tilt angle of the two-sided support components is adjusted: after receiving the command from the controller 6, the inclined hydraulic push rod 403 on the inclined support plate 402 extends or retracts at its output end, pushing the support inclined plate 404 to rotate around the transverse rotating shaft 405 at the upper end of the linkage slide plate 3. At the same time, the upper end of the support inclined plate 404 drives the bracket mounting plate 5 to move smoothly through the connecting side plate 406, ensuring that the bracket mounting plate 5 always remains in a horizontal state. During this period, the displacement sensor of the first detection plate 908 collects the angle change data of the support inclined plate 404 in real time and feeds it back to the controller 6. When the angle is adjusted to match the tilt of the top plate, the inclined hydraulic push rod 403 stops moving. Finally, the adjusting hydraulic rod 7 and the telescopic adjustment assembly are activated to achieve vertical support and longitudinal expansion: After the adjusting hydraulic rod 7 is energized, its output end pushes the support frame plate 8 to rise vertically until the support frame plate 8 is in contact with the roof of the well. At this time, the pressure sensor of the first detection plate 908 collects the roof pressure data in real time and feeds it back to the controller 6. When the pressure reaches the preset support threshold, the adjusting hydraulic rod 7 maintains the pressure. If the first detection plate 908 detects a support blind zone in the longitudinal direction, and the displacement sensor detects that the distance between the roof and the first expansion support plate 907 is >50mm, the controller 6 activates the lateral drive hydraulic rod 902. Its output end pushes the vertical connecting rod 903, which drives the fixed crossbar 904 to move laterally. The mounting connecting block 905 at the upper end of the fixed crossbar 904 then drives the first expansion support plate 907 to slide along the telescopic storage groove 906 of the support frame plate 8 until the first expansion support plate 907 is in contact with the roof. The pressure sensor reports that the pressure has reached the standard, and the lateral drive hydraulic rod 902 stops moving, completing the foundation adaptive support.

[0033] Example 2: Please refer to Figures 1-8 Based on Embodiment 1, a side-end expansion assembly is added, including a side hydraulic telescopic rod 1001 fixedly installed on both sides of the support frame plate 8, a linkage side plate 1002 fixedly connected to the side end of the side hydraulic telescopic rod 1001, a second extension support plate 1003 fixedly connected to the upper end of the linkage side plate 1002, and a second detection plate 1004 fixedly installed on the side end of the second extension support plate 1003.

[0034] Among them, the side hydraulic telescopic rod 1001 is a DYG-C-100×350 mining hydraulic telescopic rod with a rated thrust of 100kN, a stroke of 350mm, and a working pressure of 31.5MPa; the linkage side plate 1002 is made of Q355B steel with a thickness of 10mm and a size of 150×120mm; the second extension support plate 1003 is made of the same material as the first extension support plate 907 with a thickness of 18mm; the second detection plate 1004 has the same configuration as the first detection plate 908, integrating a PT124G-111 pressure sensor and a KTC-102 displacement sensor to ensure the accuracy and stability of lateral support monitoring.

[0035] During operation, after the basic support is completed in Example 1, the controller 6 receives the monitoring data from the second detection plate 1004. If the displacement sensor detects that the distance between the two sides of the support frame plate 8 and the top plate of the roadway sidewall is greater than 50mm, that is, there is a blind spot in the lateral support, the controller 6 sends an action command to the side hydraulic telescopic rod 1001. After the side hydraulic telescopic rod 1001 is energized, the output end extends and pushes the linkage side plate 1002 to move laterally. The second extension support plate 1003 at the upper end of the linkage side plate 1002 then unfolds to both sides until the displacement sensor of the second detection plate 1004 detects that the second extension support plate 1003 is in contact with the top plate and the pressure sensor reports that the pressure reaches the preset threshold. Then the side hydraulic telescopic rod 1001 stops moving, and the lateral support extension is completed. Throughout the support process, sensor data from the first detection plate 908 and the second detection plate 1004 are transmitted to the controller 6 in real time. If a sudden increase in pressure or a sudden change in displacement occurs, the controller 6 immediately initiates an emergency adjustment procedure: the adjusting hydraulic rod 7, the inclined hydraulic push rod 403, the lateral drive hydraulic rod 902, and the side hydraulic telescopic rod 1001 work together to increase the support pressure or adjust the support range to avoid the risk of roof collapse. When the coal mining machine moves to the next working face, after receiving the position signal, the controller 6 controls each hydraulic rod to retract and the bidirectional drive motor 202 to reverse, driving the device to reset and adjust to the new support position, thus achieving continuous adaptive support.

[0036] The above working principle can be summarized as follows: the bidirectional drive motor 202 drives the bidirectional threaded rotating rod 203 to rotate. Through the cooperation of the bidirectional moving sleeve 204 with the guide sliding groove 205, the guide horizontal plate 206, and the transverse guide rod 209, the linkage slide plate 3 and the upper components move laterally, adapting to different roadway widths and solving the limitations of the traditional device's "fixed position support". The inclined hydraulic push rod 403 pushes the support inclined plate 404 to rotate around the transverse rotating shaft 405. Combined with the linkage of the connecting side plate 406, the posture of the bracket mounting plate 5 is adjusted so that the upper structure fits the inclined top plate, avoiding the support gap caused by the fixed angle of the traditional device. Adjusting the hydraulic rod 7 pushes the support plate 8 to fit against the top plate, and the pressure sensor of the first detection plate 908 feeds back pressure data to ensure that the support force meets the standard; the lateral drive hydraulic rod 902 drives the first extension support plate 907 to extend and retract, eliminating the longitudinal support blind spot and improving the support coverage. The side hydraulic telescopic rod 1001 drives the second extension support plate 1003 to unfold, and the second detection plate 1004 monitors the lateral pressure and displacement in real time, realizing five-dimensional support of "lateral-oblique-vertical-longitudinal-lateral". Combined with the closed-loop control of the controller 6, it achieves intelligent adaptive adjustment and reduces manual intervention.
