Description

[0001] The present application relates to the technical field of support equipment, and in particular to an intelligent mining support device. Background Art

[0002] Underground coal mining requires tunnels to transport coal, equipment and personnel, and the stability of the internal structure of the tunnel is directly related to the safe production and economic benefits of the mine. However, the existing support device structure is relatively simple, and only uses support frames for basic support, which is difficult to meet the needs of modern coal mining. In particular, the maintenance of the end area of ​​the fully mechanized mining and fully mechanized caving working face and the advanced area of ​​the two drifts is still in the stage of in-depth development.

[0035] As mentioned in the background technology, the existing support device has a relatively simple structure and only uses a support frame for basic support. It has low strength and is difficult to meet the needs of modern coal mining. In addition, in the mechanized coal mining process, the cumbersome roof support work not only increases the labor intensity of the workers and prolongs the waiting time of the coal machine shutdown, but more seriously, it increases the danger of mining work and brings many difficulties to safe production management.

[0036] In view of the above technical problems, the present application provides an intelligent mining support device, see Figure 1, which includes an intelligent control unit, a bracket body, a control system, a propulsion module and auxiliary components; the bracket body includes a top beam 1, a support frame 2, a base 3 and a column 4, the column 4 is installed on the base 3, the support frame 2 includes a horizontal section and support seats 10 at both ends of the horizontal section, a lifting device is fixed on the base 3, the top of the lifting device is fixedly connected to the support seat 10, the column 4 is fixed on the base 3, a support platform 21 is fixedly installed on the upper end of the column 3, the lifting device passes through the support platform 21, the top beam 1 is installed on the support seat 10, and the top beam is arranged parallel to the horizontal section.

[0037] By adding a support frame under the top beam and setting a lifting device between the column and the support frame, the present application can not only improve the stability and firmness of the support device and improve the overall safety performance; it can also be adapted to the geological conditions of different mines and increase the application scope of the support device; in addition, with the setting of the control system and the intelligent control unit, the support device of the present application can be automatically adjusted according to actual needs, and can realize functions such as remote control and automatic detection, further improving the safety and adaptability of the support device, with a high degree of automation, reducing labor costs and improving efficiency; at the same time, the various components of the support device of the present application adopt a modular setting, which is convenient for rapid assembly, disassembly and maintenance.

[0038] The present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0039] like Figure 1 As shown, an intelligent mining support device includes an energy control unit, a support body, a control system, a propulsion module and auxiliary components. The support body includes a top beam 1, a support frame 2, a base 3 and a column 4. There are two bases 3, which are located at the bottom of the support body.

[0040] The bottom of the base 3 is equipped with movable wheels 5, which can drive the entire support device to move as a walking mechanism. A driving mechanism 6 is installed inside the base 3, and the driving mechanism 6 is used to drive the movable wheels 5 to rotate. The driving mechanism 6 can be a motor, a fuel engine, a hybrid power system, etc. The embodiment of the present application does not limit the driving mechanism. A guide wheel 7 is installed inside the movable wheel 5, and the guide wheel 7 serves as a guide mechanism to ensure that the support device moves as needed in the lane. Anti-skid bumps 18 are installed at the bottom of the base 3, and the anti-skid bumps 18 can play an anti-skid role.

[0041] Two columns 4 and a lifting device are fixedly installed on the top of the base 3. The lifting device is located between the two columns 14. A support platform 21 is fixedly installed on the top of the column 4. The lifting device includes a first lifting column 14 and a power support frame 15. The power support frame 15 is fixed on the base 3. The first lifting column 14 is a retractable column installed in the power support frame 15. The power support frame 15 is installed with a power device 16. The power device 16 provides power for the first lifting column 14, so that the first lifting column 14 can be retracted in the vertical direction. The first lifting column 14 passes through the support platform 21, and the upper end is fixedly connected to the support frame 2.

[0042] like Figure 1 As shown, the power support frame 15 is also fixedly connected with a second lifting column 17, which is sleeved on the outer periphery of the first lifting column 14. The second lifting column 17 passes through the support platform 21, and the upper end thereof abuts against the bottom of the support frame. The support platform 21 is provided with openings for the first lifting column 14 and the second lifting column 17, which can provide circumferential support for the first lifting column 14 and the second lifting column 17.

[0043] The support frame 2 includes a horizontal section, both ends of which are bent downward, and a support seat 10 is fixed to the bent end. The lower end of the support seat 10 is fixedly connected to the top of the first lifting column 14 and abuts against the second lifting column 17. When the lifting device needs to be raised and adjusted, the first lifting column 14 and the second lifting column 17 are lifted and lowered to a certain height h1 at the same time. At this time, the second lifting column 17 is sleeved on the outer periphery of the first lifting column 14 to jointly provide support force for the support seat 10, which can provide a more stable support effect. When the height needs to be further increased, the first lifting column 14 can continue to rise to a height of h2, and the second lifting column 17 will no longer increase the height during this process. The first lifting column 14 and the second lifting column 17 increase the height in stages, which can achieve a double-layer ring-type telescopic effect of the lifting device. The second lifting column 17 is sleeved on the outer periphery of the first lifting column 14, which can improve the stability of the lifting device.

[0044] The support seat 10 is also equipped with a telescopic device 11. The two ends of the horizontal section of the top beam 1 are bent downward to form a bent portion, and the ends of the bent portion are fixedly connected to the top of the telescopic device 11. When height adjustment is required, the first lifting column 14 drives the support seat 2 and the top beam 1 to move up and down; when the lifting height of the lifting column 14 is difficult to meet the needs, or the force on the top beam 1 is uneven and needs further fine-tuning, the telescopic devices 11 at the left and right ends of the top beam 1 can be extended and retracted up and down to drive the top beam 1 to further rise or fall a certain height, or adjust the height of the left and right ends of the top beam 1. Through the extension and contraction of the telescopic device, uniform force and stable support of the top plate are achieved.

[0045] A telescopic rod 19 is also installed on the top beam 1. The telescopic rod 19 can be extended in a direction perpendicular to the horizontal section of the top beam 1, so that the width supported by the top beam 1 can be increased.

[0046] A reinforcing rib 12 is installed on the inner side of the bent portion of the top beam 1 , and the reinforcing rib 12 can improve the strength of the bent portion of the top beam 1 to increase the stability of the support of the top beam 1 .

[0047] like Figure 1 As shown, a stabilizing bracket 20 is also installed on the supporting platform 21. When the supporting seat 10 of the supporting frame 2 is at the lowest height, the upper end of the stabilizing bracket 20 abuts against the lower end of the supporting seat 10, providing support for the supporting frame 2 and the top beam 1, further ensuring the firmness and stability of the support of the entire supporting device.

[0048] The lower end of the support platform 21 is located outside the two pillars 4, and two stabilizing frames 22 are installed. The lower end of the stabilizing frame 22 is fixed with a buffer column 23, and the other end of the buffer column 23 is fixed to the upper surface of the base 3. The stabilizing frame 22 and the buffer column 23 are inclined to form a certain angle with the base 3. The stabilizing frame 22 and the buffer column 23 can provide a certain buffer support effect for the support platform 21, further improving the stability of the entire device.

[0049] A connector 8 is installed on the side of the horizontal section of the top beam 1, and the connector 8 can realize the connection between two adjacent support devices. A locking mechanism 9 is also installed on the base 3. When the support device is pushed to a predetermined position, the locking mechanism 9 can tightly fix the support body and the base 3 to ensure that the support device remains stable when it is subjected to the pressure of the top plate.

[0050] like Figure 1 As shown, an operating table is installed on the horizontal section of the support frame 2, and the entire control system is installed inside the operating table. The operating table is installed with a sensor analysis module 26, an electric control system 28, and an alarm system 29. The control panel of the operating table adopts a touch screen design, and the operator can control the action of the support device through this control panel.

[0051] The support device also includes an intelligent control unit, which includes an integrated PLC controller 25 installed inside the operating table, a data analysis module 27, and sensors 24 installed on the top beam 1 and the support frame 2. The sensors 24 can also be installed at other locations that need to be monitored. The sensors 24 include pressure sensors, displacement sensors, inclination sensors, etc., which can monitor the state of the support in real time, such as the pressure, inclination, displacement, etc.

[0052] The electric control system of the present application can realize automatic control of the action of the support device. When the sensor detects an abnormality, the alarm system 29 can generate sound and light alarms. The integrated PLC controller 25, data analysis module 27, and sensor analysis module 26 can analyze the signal transmitted back by the sensor 24, monitor the pressure at the support top plate and the angle between the support device frames in real time, and combine with the Internet of Things technology to process the collected data and finally display it on the display screen.

[0053] The specific operation process of the support bracket of this application is as follows:

[0054] 1. Start the intelligent control unit operation process

[0055] First, the operator must activate the intelligent control unit, which has an integrated PLC controller, sensor and data analysis module. At this time, the sensor begins to monitor the pressure condition at the support top plate and the angle change between the support frames in real time. The monitored data is analyzed by the data processing module and finally displayed on the display screen on the operating console in the form of intuitive charts or numerical values. This step ensures that the operator can obtain key information on the support status in a timely manner and provide data support for subsequent adjustments.

[0056] 2. Adjust the support body to meet the roadway conditions

[0057] The operator makes fine adjustments to the support body through the control panel of the operating table. Specifically, it includes: adjusting the height of the support body by controlling the extension and retraction of the lifting device; further adjusting the height of the support body and the force distribution of the top plate by adjusting the extension and retraction of the extension device between the top beam 1 and the support frame 2; and adjusting the angle of the support body by rotating the connection joint between the top beam 1 and the support frame 2. The above adjustments are aimed at ensuring that the support body can fully adapt to the specific height, width and other needs of the on-site laneway.

[0058] 3. Push the device to the designated position

[0059] After the bracket body is adjusted, the operator starts the drive mechanism, and the drive mechanism 6 drives the movable wheels 5 in the walking mechanism to smoothly move the device along the roadway. During this process, the sensor continuously monitors the running status of the bracket, including but not limited to displacement, inclination and pressure. Once abnormal data is detected, the alarm system is immediately activated and sends out an audible and visual alarm signal to remind the operator to take corresponding measures.

[0060] 4. Lock the bracket to ensure stability

[0061] When the device is advanced to the predetermined support position, the operator activates the locking mechanism 9. At this time, the locking mechanism tightly fixes the support body and the base 3 to ensure that the support device remains stable when subjected to the top plate pressure to prevent displacement.

[0062] 5. Adjust the telescopic device and the support device to stabilize the top plate

[0063] According to the specific needs of supporting the roof, the operator adjusts the telescopic devices 11 on both sides of the support frame 2 and the telescopic rods 19 of the top beam 1. Through the extension and contraction of the telescopic devices and the fine adjustment of the telescopic rods 19, the roof is evenly stressed and stably supported, thus completing the entire support operation process.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
