Currently, the ultra-high extraction hydraulic support connection devices used in high-extraction fully mechanized longwall mining projects have some shortcomings in practical applications.

[0003] Traditional connecting devices struggle to achieve efficient balance adjustment of the supports during operation. Due to the uncertainty of geological conditions at coal mining faces, these traditional connecting components are ill-suited to the changing working environment, lacking real-time feedback and dynamic adjustment mechanisms, and unable to respond promptly to potential instability in the supports during operation. This significantly limits the adaptability and safety of the supports, hindering the efficient execution of mining projects. Summary of the Invention

Multiple telescopic parts are spaced apart at the top of the hydraulic column along the circumferential direction. One end of each telescopic part is hinged to the hydraulic column, and the other end of each telescopic part is hinged to the top plate. The telescopic parts are used to support the top plate. A gyroscope is mounted on the top plate and is used to monitor the tilt angle of the top plate. A control unit, which is connected to the gyroscope and the telescopic part; The control unit controls multiple telescopic parts to move separately based on the tilt angle information of the top plate monitored by the gyroscope, so as to adjust the top plate to a horizontal state.

[0006] The ultra-high mining height hydraulic support connection device in this embodiment of the invention uses a gyroscope to achieve real-time monitoring of the roof tilt state, providing precise data support for support balance adjustment and solving the problem of lack of real-time feedback in traditional devices. A dynamic adjustment mechanism is established through the control unit, which can promptly issue action commands to the telescopic section based on monitoring data, achieving rapid response to the support status. Differential movement of the telescopic section allows for targeted adjustment of the roof posture, achieving efficient balance adjustment of the support and adapting to varying geological working environments. The synergistic effect of each component enhances the adaptability and operational safety of the support, reduces the occurrence of instability, and ensures the efficient progress of mining projects.

[0007] In some embodiments, the vertical central axis of the top plate is perpendicular to the top plate to support the top plate.

[0008] In some embodiments, the telescopic portion is disposed obliquely between the top plate and the hydraulic column relative to the vertical direction, and the telescopic portion extends in a direction away from the vertical central axis of the hydraulic column to distribute the force applied to the top plate by the multiple telescopic portions.

[0009] In some embodiments, the telescopic part includes a hydraulic cylinder and a hydraulic pump, the hydraulic pump being connected to the hydraulic cylinder, and the hydraulic pump being used to control the amount of hydraulic oil in the hydraulic cylinder to cause the hydraulic cylinder to extend or retract.

[0010] In some embodiments, the hydraulic pump is connected to the control unit, and the control unit controls the start and stop of the hydraulic pump based on the tilt angle information monitored by the gyroscope.

[0011] In some embodiments, a mounting plate is provided at the top of the hydraulic column, and a plurality of telescopic parts are provided on the mounting plate, the mounting plate being used to install the telescopic parts.

[0014] In some embodiments, the control unit includes a data preprocessor that filters and calibrates the acquired angle data to ensure that the data is accurate and reliable.

[0015] The method for connecting hydraulic supports with extremely high mining heights according to embodiments of the present invention utilizes the hydraulic support connection device for extremely high mining heights described in any of the above embodiments.

[0020] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] like Figure 1 , Figure 2 As shown, the ultra-high mining height hydraulic support connection device of this invention includes a top plate 1, a hydraulic column 5, multiple telescopic parts 3, a gyroscope 7, and a control unit.

[0022] Top plate 1 is used for connection to the top of the hydraulic support; The hydraulic column 5 is installed on the lower side of the top plate 1 and is used to connect to the bottom of the hydraulic support. Multiple telescopic parts 3 are spaced apart at the top of the hydraulic column 5 along the circumferential direction. One end of the telescopic part 3 is hinged to the hydraulic column 5, and the other end of the telescopic part 3 is hinged to the top plate 1. The telescopic part 3 is used to support the top plate 1. The gyroscope 7 is mounted on the top plate 1 and is used to monitor the tilt angle of the top plate 1. The control unit is connected to the gyroscope 7 and the telescopic part 3; The control unit controls multiple telescopic parts 3 to move according to the tilt angle information of the top plate 1 monitored by the gyroscope 7, so as to adjust the top plate 1 to a horizontal state.

[0023] The ultra-high mining height hydraulic support connection device in this embodiment of the invention uses a gyroscope to achieve real-time monitoring of the roof tilt state, providing precise data support for support balance adjustment and solving the problem of lack of real-time feedback in traditional devices. A dynamic adjustment mechanism is established through the control unit, which can promptly issue action commands to the telescopic section based on monitoring data, achieving rapid response to the support status. Differential movement of the telescopic section allows for targeted adjustment of the roof posture, achieving efficient balance adjustment of the support and adapting to varying geological working environments. The synergistic effect of each component enhances the adaptability and operational safety of the support, reduces the occurrence of instability, and ensures the efficient progress of mining projects.

[0024] Specifically, the gyroscope 7 monitors the tilt angle information of the top plate 1 in real time and transmits this information to the control unit; after receiving the tilt angle information transmitted by the gyroscope 7, the control unit processes and analyzes the data; based on the analysis results, the control unit sends control commands to multiple telescopic parts 3 spaced apart along the circumference; the telescopic parts 3 respond to the control commands and move accordingly (because one end of the telescopic part 3 is hinged to the top of the hydraulic column 5 and the other end is hinged to the top plate 1), ultimately adjusting the top plate 1 to a horizontal state; the hydraulic column 5 is located on the lower side of the top plate 1, providing basic support for the entire device, while the top plate 1 is used to connect to the top of the hydraulic support, ensuring stable assembly of the device and the hydraulic support.

[0025] Furthermore, the gyroscope 7 and the control unit are existing technologies and will not be described in detail here.

[0026] In some embodiments, such as Figure 1 , Figure 2 As shown, the vertical central axis of the top plate 1 is perpendicular to the top plate 1 to support the top plate 1.

[0027] The ultra-high mining height hydraulic support connection device in this embodiment of the invention provides a stable benchmark for the balance adjustment of the support through the vertical central axis design of the top plate, ensuring the accuracy of the adjustment process; through the reasonable structural layout of the top plate, it realizes uniform force transmission, reduces local stress concentration, and improves the overall load-bearing capacity of the device.

[0028] Specifically, the vertical center axis of the top plate 1 is set perpendicular to the top plate 1, forming a stable force reference. This vertical structure enables the top plate 1 to uniformly transmit the force to the hydraulic column 5 in the vertical direction when receiving the support force of the telescopic part 3. With the help of the gyroscope 7 to monitor the tilt angle of the top plate 1 and the control unit to control the command, the movement and adjustment of the telescopic part 3 is always based on the vertical center axis of the top plate 1, ensuring that the top plate 1 accurately returns to a horizontal state.

[0029] In some embodiments, such as Figure 1 , Figure 2 As shown, the telescopic part 3 is inclined between the top plate 1 and the hydraulic column 5 relative to the vertical direction. The telescopic part 3 extends in a direction away from the vertical central axis of the hydraulic column 5 to disperse the force applied to the top plate 1 by multiple telescopic parts 3.

[0030] The ultra-high mining height hydraulic support connection device in this embodiment of the invention, through the inclined extension design of the telescopic part, disperses the force application position on the roof, avoids local force concentration, and improves the uniformity of roof support; through the inclined layout of the telescopic part, it expands the support coverage area, enhances the ability to adjust the posture of different areas of the roof, and improves the flexibility of balance adjustment; through the inclined setting of the telescopic part, the support force is decomposed in multiple directions, better resisting the lateral force in complex geological environments, and strengthening the overall stability of the support.

[0031] Specifically, the telescopic part 3 is set between the top plate 1 and the hydraulic column 5 in an inclined posture relative to the vertical direction, and extends in a direction away from the vertical central axis of the hydraulic column 5. This inclined extension structure disperses the force application positions of multiple telescopic parts 3 on the top plate 1, forming a multi-point, wide-coverage support pattern. When the gyroscope 7 detects that the top plate 1 is tilted, the control unit sends a command to the corresponding telescopic part 3 according to the tilt information. The tilted telescopic part 3 generates a support force along its own tilt direction through the telescopic action, and uses the dispersed force application points to achieve precise attitude correction of the top plate 1, and finally adjusts the top plate 1 to a horizontal state.

[0032] In some embodiments, such as Figure 1 , Figure 2 As shown, the telescopic part 3 includes a hydraulic cylinder and a hydraulic pump. The hydraulic pump is connected to the hydraulic cylinder and is used to control the amount of hydraulic oil in the hydraulic cylinder so that the hydraulic cylinder can extend and retract.

[0033] The ultra-high mining height hydraulic support connection device in this embodiment of the invention achieves precise adjustment of the hydraulic cylinder's extension and retraction stroke through precise control of the hydraulic pump, ensuring the accuracy of roof posture correction; the extension and retraction drive of the hydraulic cylinder provides stable and sufficient support force, enhancing the load-bearing and adjustment capacity of the roof; the cooperation between the hydraulic pump and the hydraulic cylinder enables the rapid response action of the extension and retraction section, promptly addressing roof tilting and improving dynamic adjustment efficiency; and the characteristics of the hydraulic structure give the extension and retraction section strong load-bearing capacity, adapting to the complex stress environment of mining engineering and extending the service life of the device.

[0034] Specifically, after the gyroscope 7 detects the tilt angle information of the top plate 1, it transmits the data to the control unit; the control unit sends a control command to the hydraulic pump in the telescopic part 3; the hydraulic pump responds to the command and adjusts the hydraulic oil volume of the input or output hydraulic cylinder; the hydraulic cylinder realizes the telescopic action through the change of hydraulic oil volume, thereby driving the top plate 1 to adjust its posture, and finally making the top plate 1 reach a horizontal state.

[0035] Furthermore, hydraulic cylinders and hydraulic pumps are existing technologies and will not be described in detail.

[0036] In some embodiments, the hydraulic pump is connected to the control unit, which controls the start and stop of the hydraulic pump based on the tilt angle information monitored by the gyroscope 7.

[0037] The ultra-high mining height hydraulic support connection device in this embodiment of the invention achieves on-demand control of the hydraulic pump's start and stop through the precise judgment and command issuance of the control unit, ensuring the timeliness and pertinence of adjustment actions; through the controllable start and stop of the hydraulic pump, ineffective operation is avoided, energy consumption is reduced, and the economic efficiency of the device operation is improved; through the linkage of the gyroscope, control unit, and hydraulic pump, a closed-loop control is formed to ensure the stable maintenance of the roof's horizontal state.

[0038] Specifically, the gyroscope 7 continuously monitors the tilt angle information of the top plate 1 and transmits this information to the control unit in real time. The control unit judges the received tilt angle information. If the top plate 1 deviates from the horizontal state, it sends a start command to the hydraulic pump. The hydraulic pump starts in response to the command of the control unit, adjusts the hydraulic oil in the hydraulic cylinder, and drives the hydraulic cylinder to extend and retract. As the hydraulic cylinder extends and retracts, the attitude of the top plate 1 is adjusted. When the gyroscope 7 detects that the top plate 1 has returned to the horizontal state, the control unit sends a stop command to the hydraulic pump, and the hydraulic pump stops working.

[0039] In some embodiments, such as Figure 1 , Figure 2 As shown, the top of the hydraulic column 5 is provided with a mounting plate 4, and multiple telescopic parts 3 are provided on the mounting plate 4. The mounting plate 4 is used to install the telescopic parts 3.

[0040] The ultra-high mining height hydraulic support connection device in this embodiment of the invention provides a stable installation benchmark through the mounting plate, ensuring the arrangement accuracy of multiple telescopic parts 3 and guaranteeing the synchronization of adjustment actions; the mounting plate realizes a stable connection between the telescopic parts and the hydraulic column, enhancing the connection reliability between components and improving the overall load-bearing capacity of the device; the mounting plate simplifies the assembly process of the telescopic parts through its transition installation function, reducing the difficulty of later maintenance and replacement; the mounting plate disperses the force transmitted by the telescopic parts, avoiding localized force concentration at the top of the hydraulic column and extending the service life of the hydraulic column.

[0041] Specifically, a mounting plate 4 is fixedly installed at the top of the hydraulic column 5 to provide a mounting carrier for multiple telescopic parts 3; the multiple telescopic parts 3 are arranged at intervals along the circumferential direction through the mounting plate 4 and are hingedly connected to the mounting plate 4 (associated with the hydraulic column 5).

[0042] In some embodiments, such as Figure 1 , Figure 2 As shown, the mounting plate 4 is provided with a plurality of first hinge seats 6, which correspond one-to-one with a plurality of telescopic parts 3, and the first hinge seats 6 are hinged to the bottom of the telescopic parts 3.

[0043] The ultra-high mining height hydraulic support connection device in this embodiment of the invention achieves precise hinged connection between the telescopic part and the mounting plate through the first hinge seat, ensuring the flexibility of the telescopic movement and improving the smoothness of posture adjustment; the one-to-one correspondence of the first hinge seats ensures the accurate installation position of each telescopic part, avoids movement interference, and ensures the coordination of multiple telescopic parts working together; the first hinge seat enhances the connection stability between the telescopic part and the mounting plate, disperses the force transmission, reduces wear on the connection parts, and extends the service life of the components; the first hinge seat simplifies the hinge assembly process of the telescopic part, reduces installation difficulty, and provides convenience for later inspection and maintenance.

[0044] Specifically, the mounting plate 4 is provided with multiple first hinge seats 6 corresponding to multiple telescopic parts 3, and each first hinge seat 6 forms a hinge engagement with the bottom of a telescopic part 3; the control unit sends telescopic commands to each telescopic part 3 according to the tilt information of the top plate 1 monitored by the gyroscope 7; the telescopic part 3 performs telescopic movement with the first hinge seat 6 as the hinge fulcrum, and drives the top plate 1 to adjust its posture through the hinge connection with the top plate 1, so that the top plate 1 reaches a horizontal state.

[0045] In some embodiments, such as Figure 1 , Figure 2As shown, a plurality of second hinge seats 2 are provided on the top plate 1, and the plurality of second hinge seats 2 correspond one-to-one with a plurality of telescopic parts 3. The second hinge seats 2 are hinged to the top of the telescopic parts 3.

[0046] The ultra-high mining height hydraulic support connection device in this embodiment of the invention provides stable upper hinge support for the telescopic part through the second hinge seat, ensuring the flexibility and accuracy of the telescopic part's movement and improving the smoothness of roof posture adjustment; the one-to-one correspondence of the second hinge seats ensures accurate connection positions between multiple telescopic parts and the roof, avoiding interference during movement and ensuring the coordination of multiple components working together; the second hinge seat strengthens the connection strength between the telescopic part and the roof, disperses local stress during support force transmission, reduces wear at the connection points, and extends the overall service life of the device; the second hinge seat simplifies the assembly process of the telescopic part and the roof, reduces the difficulty of installation and subsequent maintenance, and improves the ease of device maintenance.

[0047] Specifically, multiple second hinge seats 2 are provided on the top plate 1 corresponding to multiple telescopic parts 3, and each second hinge seat 2 forms a hinge engagement with the top of a telescopic part 3; the control unit sends telescopic control commands to each telescopic part 3 according to the tilt information of the top plate 1 monitored by the gyroscope 7; the telescopic part 3 uses the second hinge seat 2 as the upper hinge fulcrum, and in conjunction with the hinge of the bottom with the first hinge seat 6, it performs telescopic movement, thereby driving the top plate 1 to adjust to a horizontal state.

[0048] In some embodiments, the control unit includes a data preprocessor that filters and calibrates the acquired angle data to ensure that the data is accurate and reliable.

[0049] The ultra-high mining height hydraulic support connection device in this embodiment of the invention removes interference noise from angle data through filtering by a data preprocessor, ensuring the purity of data transmission; corrects data deviations through the calibration function of the data preprocessor, ensuring the accuracy and reliability of angle data; provides a scientific basis for the control unit to issue commands through the precise data output by the data preprocessor, improving the accuracy of roof attitude adjustment; and enhances the dynamic response stability of the device through the collaboration of the data preprocessor, control unit, and gyroscope, adapting to the working requirements of complex geological environments.

[0050] Specifically, after the gyroscope 7 monitors the tilt angle information of the top plate 1, it transmits the raw data to the control unit. The data preprocessor in the control unit receives the raw angle data, filters it, and removes interference noise. The data preprocessor further calibrates the filtered angle data to correct data deviation. The accurate angle data after filtering and calibration is fed back to the control unit, which then sends precise telescopic control commands to the telescopic part 3 to adjust the top plate 1 to a horizontal state.

[0051] Furthermore, the data preprocessor is existing technology and will not be described in detail here.

[0052] The method for connecting hydraulic supports with extremely high mining heights according to embodiments of the present invention utilizes the hydraulic support connection device for extremely high mining heights described in any of the above embodiments. The method includes the following steps: Connection support: The top plate of the connecting device is fixedly connected to the top of the hydraulic support, and the hydraulic column of the connecting device is fixedly connected to the bottom of the hydraulic support, so that multiple telescopic parts arranged at intervals along the circumference are respectively hinged between the top of the hydraulic column and the top plate to form a support structure for the top plate. Angle acquisition: Activate the gyroscope installed on the top plate to monitor the tilt angle information of the top plate in real time, and transmit the tilt angle information to the control unit connected to the gyroscope in real time; Information Judgment: After receiving the tilt angle information, the control unit determines whether the top plate is in a horizontal state. If not, it generates a corresponding telescopic adjustment command based on the tilt angle information and sends the telescopic adjustment command to multiple telescopic parts connected to the control unit. Horizontal adjustment: After receiving the telescopic adjustment command, multiple telescopic parts move along their own telescopic direction. By adjusting the telescopic amount of different telescopic parts, the force distribution on the top plate is balanced until the gyroscope detects that the tilt angle of the top plate meets the horizontal requirements. The control unit then controls the multiple telescopic parts to stop moving, thus completing the horizontal adjustment of the top plate.

[0053] The ultra-high mining height hydraulic support connection method in this embodiment of the invention constructs a stable support structure through a connection and support step, providing a solid foundation for subsequent horizontal adjustment and ensuring the reliability of the connection between the device and the hydraulic support; the angle acquisition step enables real-time capture of the tilt angle, providing timely and continuous data support for adjustment actions and avoiding untimely adjustments due to information lag; the information judgment step accurately identifies the roof state, ensuring the pertinence of telescopic adjustment commands, avoiding ineffective adjustments, and improving adjustment efficiency; the differentiated telescopic control in the horizontal adjustment step achieves dynamic balance of roof forces, ensuring the roof quickly returns to a horizontal state and enhancing the working stability of the support; the orderly connection of each step forms a complete closed-loop adjustment process, adapting to complex geological environments and improving the efficiency and safety of mining engineering.

[0054] Specifically, Perform the connection and support steps: fix the top plate 1 to the top of the hydraulic support, fix the hydraulic column 5 to the bottom of the hydraulic support, and hinge multiple telescopic parts 3 arranged at intervals along the circumference between the top of the hydraulic column 5 and the top plate 1 to form a support structure. Execution angle acquisition steps: Activate the gyroscope 7 on the top plate 1. The gyroscope 7 monitors the tilt angle information of the top plate 1 in real time and transmits the information to the control unit in real time. Execution information judgment steps: After receiving the tilt angle information, the control unit determines whether the top plate 1 is horizontal. If it is not horizontal, it generates a telescopic adjustment command based on the information and sends it to multiple telescopic parts 3. The horizontal adjustment process is as follows: After receiving the command, the multiple telescopic parts 3 move along their own telescopic direction. By adjusting their respective telescopic amounts, they balance the force distribution on the top plate 1 until the gyroscope 7 detects that the tilt angle of the top plate 1 meets the horizontal requirements. Then, the control unit controls the telescopic parts 3 to stop moving, thus completing the adjustment.

A method for connecting a hydraulic support for ultra-high mining height, comprising the hydraulic support connection device for ultra-high mining height according to any one of claims 1-9, characterized in that, Includes the following steps: Connection support: The top plate of the connecting device is fixedly connected to the top of the hydraulic support, and the hydraulic column of the connecting device is fixedly connected to the bottom of the hydraulic support, so that multiple telescopic parts arranged at intervals along the circumferential direction are respectively hinged between the top of the hydraulic column and the top plate to form a support structure for the top plate; Angle acquisition: Activate the gyroscope installed on the top plate, monitor the tilt angle information of the top plate in real time through the gyroscope, and transmit the tilt angle information to the control unit connected to the gyroscope in real time; Information Judgment: After receiving the tilt angle information, the control unit determines whether the top plate is in a horizontal state. If not, it generates a corresponding telescopic adjustment command based on the tilt angle information and sends the telescopic adjustment command to the multiple telescopic parts connected to the control unit. Horizontal adjustment: After receiving the telescopic adjustment command, the multiple telescopic parts move along their own telescopic direction. By adjusting the telescopic amount of different telescopic parts, the force distribution of the top plate is balanced until the gyroscope detects that the tilt angle of the top plate meets the horizontal requirements. Then, the control unit controls the multiple telescopic parts to stop moving, thus completing the horizontal adjustment of the top plate.
