Description

Technical Field

[0001] The invention relates to the technical field of mine engineering support technology, in particular to a fixing device for mine engineering support. Background Art

[0002] Mining engineering support refers to a series of support and reinforcement measures taken during the mining process to maintain the stability of underground engineering structures such as underground tunnels and mining areas and to prevent surrounding rock from deformation, collapse and other damage. It is a key link in ensuring safe production in mines.

[0003] In mining engineering, support brackets play a vital role in mining engineering support. Support methods such as wooden support and metal support mainly work by bearing the pressure from the surrounding rock through their own structure, and reasonably dispersing and transmitting these pressures to maintain the stability of underground spaces such as tunnels and mining areas.

[0004] Under complex geological conditions, especially in areas of high stress or rich aquifers, wooden support structures have a greater risk of failure due to their own material properties and structural limitations. Although metal supports have higher strength and stability, they are usually larger and more bulky. In some narrow passages and bends, it becomes difficult to transport large metal support components, and the installation process is relatively complicated, which limits the convenience of using metal supports under complex geological conditions.

[0020] Preferably, the strain sensor, temperature and humidity sensor, and vibration sensor are all electrically connected to the display screen.

[0021] Working principle: First, the screen and other components need to be transported to underground tunnels, mining sites and other underground projects. Then, appropriate holes are drilled at equal distances on the top of the tunnel, and the screen is laid on the top of the tunnel. After that, the expansion tube in the fixing mechanism is inserted into the corresponding hole. If it cannot be fully inserted into the hole, the expansion tube can be pushed into the hole with the help of a tool, and then the hexagonal hole at the bottom of the screw can be rotated with the tool to pull the screw out of the expansion tube. At this time, the conical block will squeeze the expansion tube, causing the outer diameter of the expansion tube to increase, so that it is aligned with the hole. The wall is tightly squeezed, thereby generating friction, so that it is firmly fixed on the top of the tunnel, and the support plate will lift the barrier, so that the barrier contacts the inner wall of the tunnel to prevent the fragments of the surrounding rock from falling. Then, the support mechanism is placed at a suitable position in the tunnel, and the arc-shaped protrusion 1 at one end of the arc plate is inserted into the arc plate 2, and the card block 1 and the card block 2 are clamped to the connection between the arc plate 1 and the arc plate 2, and they are fixed together with bolts, and a strain sensor is arranged at the connection between the card block 1 and the card block 2, and the strain sensor is attached to the surface. The size and direction of the strain can be measured to understand the stress state of the component. After the arc plate 1 and the arc plate 2 are combined, the arc-shaped protrusion 2 at the other end of the arc plate 1 is inserted into the protruding groove of the support rod, and then the limit plate 3 on the arc plate 1 is connected to the support rod with bolts. Then, through the adjustment component in the support mechanism, the worm is rotated with the help of a tool to drive the screw on the worm gear, and the screw drives the fixed plate fixed inside the square tube to move on the screw, so as to adjust the height of the base to adapt to different situations. After that, the seismic isolation mechanism on the arc plate 1 and the arc plate 2 is contacted with the blocking net. By adjusting the two nuts, the nuts are used to squeeze the spring so that the deformation size of the spring is adjusted, so that the abutment plate is in contact with the blocking net, or in contact with the corresponding groove on the blocking net to enhance stability. The display screen can also display the values ​​of the temperature and humidity sensors and vibration sensors set on the arc plate 1 and the arc plate 2, and the values ​​of the temperature and humidity sensors and vibration sensors are displayed in real time and accurately, so that the staff can understand the environmental conditions of the tunnel and ensure safe production in the mine.

[0022] The present invention provides a fixing device for supporting mining projects. It has the following beneficial effects:

[0023] 1. The seismic isolation mechanism adopted in the present invention can effectively prevent the support bracket from shifting or falling off due to vibration in the mining environment, such as mine car operation, mine blasting, and groundwater scouring and other adverse factors. By reducing the impact of vibration on the support structure, the integrity and effectiveness of the structure under dynamic loads are ensured, thereby avoiding support failure and ensuring the safety of mining operations.

[0024] 2. The present invention can adjust the height of the support mechanism through the adjustment component, and the support column enables it to effectively bear and disperse the surrounding rock pressure, thereby preventing the deformation and collapse of the tunnel surrounding rock, ensuring the stability of the tunnel structure, and providing the necessary basic conditions for safe production in mines. Since the adjustment component uses a worm and worm gear mechanism to change the height of the support mechanism, and the worm and worm gear have a self-locking function, it can provide effective support for key parts such as the mine roof, thereby ensuring the safety of operators and the normal operation of equipment, maintaining the stability of the mine, and reducing safety accidents and economic losses caused by mine collapse.

[0025] 3. The present invention achieves stable fixation through the coordinated work of arc plate 1, arc plate 2 and other components and the blocking net by using expansion screws. The blocking net prevents the falling of surrounding rock fragments, enhances the protection function for personnel and equipment in the tunnel, and reduces the risk of safety accidents. The fixing mechanism is detachable and easy to reuse, thereby improving the utilization efficiency of resources and reducing support costs. A display component is also provided. The temperature and humidity sensors and vibration sensors in the display component are electrically connected to the display screen, which can accurately display the temperature, humidity and vibration values ​​in the tunnel in real time, so that the staff can understand the tunnel environment in time and take corresponding measures according to the monitoring data to ensure production safety and normal operation of equipment.

[0036] Example:

[0037] Please see attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 With attached Figure 7The embodiment of the present invention provides a fixing device for supporting mining engineering, including a supporting mechanism 2, which is used to maintain the stability of the connecting assembly, prevent the surrounding rock in the space such as the tunnel or the mining area from deformation and collapse, provide a solid supporting force, ensure that in a complex underground environment, the surrounding rock can maintain a relatively stable state, and ensure the safety of mining operations. The supporting mechanism 2 includes a supporting rod 201, and the supporting rod 201 is used as the main bearing component of the supporting mechanism 2. A convex groove 202 is provided on the top of the supporting rod 201. The convex groove 202 is used to engage with the arc-shaped convex block 212 in the connecting assembly to achieve a stable connection between the connecting assembly and the supporting mechanism 2, so that the entire supporting structure can form an organic whole. In order to withstand the pressure from the surrounding rock, a square groove 203 is provided at the bottom of the support rod 201. The square groove 203 provides space for installation and operation of other internal components, ensuring the normal operation of the adjustment components and other components. A square cylinder 205 slides inside the square groove 203. The square cylinder 205 can slide in the square groove 203, so that the height of the support mechanism 2 can be adjusted within a certain range to adapt to tunnels or mining environments of different heights, thereby improving the versatility and adaptability of the support mechanism. A base 2010 is provided at the bottom of the square cylinder 205. The base 2010 is used to increase the contact area with the ground or the bottom of the tunnel, disperse the pressure borne by the support mechanism, and make the support more stable and reliable.

[0038] The connecting assembly is located above the supporting mechanism 2, and is used to better withstand and disperse the surrounding rock pressure. The connecting assembly plays an important role in connecting various parts and transmitting the surrounding rock pressure evenly, just like the connecting part of a bridge, connecting different components together to work together. The connecting assembly includes an arc plate 9, and a limit plate 3 13 is arranged at the lower end of the arc plate 9. The limit plate 3 13 can play a limiting role. The lower part of the limit plate 3 13 is provided with an arc-shaped protrusion 2 12, and the arc-shaped protrusion 2 12 is engaged with the protrusion 202 at the top of the supporting rod 201.

The upper end of the arc plate 1 9 is provided with an arc-shaped protrusion 11, and the arc-shaped protrusion 11 is snapped into the inside of the arc plate 2 10, so that the connection between the arc plate 1 9 and the arc plate 2 10 is tighter, and can work better together to jointly withstand the pressure from the surrounding rock. The connection between the arc plate 1 9 and the arc plate 2 10 is provided with a connection mechanism 3, and the connection mechanism 3 further strengthens the connection stability between the arc plate 1 9 and the arc plate 2 10;

[0039] The connecting mechanism 3 is arranged on the outside of the connecting component, and is used to connect and fix the connecting component to increase stability. The connecting mechanism 3 includes a clamping block 1 301 and a clamping block 2 302. The clamping block 1 301 and the clamping block 2 302 are both clamped at the connection between the arc plate 1 9 and the arc plate 2 10, and the clamping block 1 301 and the clamping block 2 302 are connected to the arc plate 1 9 and the arc plate 2 10 through multiple bolts. The combination of clamping and bolt connection not only ensures the tightness of the connection, but also provides sufficient strength to make the connection between the arc plate 1 9 and the arc plate 2 10 more secure and not easy to loosen or separate. Multiple limit rods 303 are equidistantly arranged at the adjacent diagonals of the clamping block 1 301 and the clamping block 2 302, and multiple limit rods 303 are equidistantly arranged at the adjacent diagonals of the clamping block 1 301 and the clamping block 2 302. The limiting hole 304 and the limiting rod 303 are all engaged with the corresponding limiting hole 304. The matching design of the limiting rod 303 and the limiting hole 304 further enhances the connection accuracy and stability between the card block 1 301 and the card block 2 302, and prevents the occurrence of dislocation or offset during installation and use. A strain sensor 305 is arranged between the top of the card block 1 301 and the card block 2 302. The strain sensor 305 is used to be attached to the surface of the connection between the card block 1 301 and the card block 2 302. The strain sensor 305 can monitor the stress of the connection mechanism 3 in real time. By measuring the size and direction of the strain, the staff can understand the deformation of the connection component when it is subjected to the surrounding rock pressure, so as to take corresponding measures to avoid safety accidents.

[0040] The seismic isolation mechanism 5 is located above the connecting assembly, and a blocking net 1 is arranged above the seismic isolation mechanism 5 to reduce the impact of vibration on the stability of the support and surrounding rock, absorb and disperse vibration energy, and reduce the impact of vibration on the entire support structure, and the blocking net 1 is used to prevent the falling of fragments of the surrounding rock. The seismic isolation mechanism 5 includes a bolt barrel 501, and the bolt barrel 501 is equidistantly arranged on the upper side of the arc plate 9 and the arc plate 2 10. The outer side of the bolt barrel 501 is threadedly connected with a plurality of nuts 502. By adjusting the position of the nut 502, the compression degree of the spring 503 can be changed, thereby adjusting the seismic isolation effect of the seismic isolation mechanism 5. A limiting plate 506 is arranged inside the bolt barrel 501. The limiting plate 506 can limit the moving range of the guide rod 505 to prevent the guide rod 505 from escaping from the bolt barrel 501. The limiting plate 506 A guide rod 505 is arranged in the middle part, and the guide rod 505 provides a guiding effect for the movement of the limit plate 2 507 and the abutment plate 504. A limit plate 2 507 is arranged on the upper end of the guide rod 505, and the limit plate 2 507 is convenient for installing the abutment plate 504. A abutment plate 504 is arranged on the top of the limit plate 2 507, and the pressure from the blocking net 1 is transmitted to the spring 503, and the vibration energy is absorbed by the elastic deformation of the spring 503. A spring 503 is arranged between the nut 502 and the abutment plate 504, which can effectively reduce the transmission of vibration. The abutment plate 504 is arranged on the lower side of the blocking net 1.

The screw rod 204 plays a role in transmitting power and realizing displacement in the entire adjustment process. The lower end of the screw rod 204 is rotatably connected to a movable plate 206. The movable plate 206 can provide a certain support and stability for the screw rod 204 to prevent the screw rod 204 from shaking or bending during the rotation process. The movable plate 206 slides inside the square tube 205. A fixed plate 207 is provided on the upper side of the interior of the square tube 205, and the screw rod 204 penetrates the fixed plate 207. When the screw rod 204 rotates, it drives the fixed plate 207 to move up and down, thereby pulling the square tube 205 to slide in the square groove 203. The worm 209 is meshed with the worm wheel 208, and the transmission of the worm wheel 208 and the worm 209 has a self-locking function, which can maintain the stability of the support mechanism 2 after the height is adjusted, and will not easily change the height due to the pressure of the surrounding rock or other external forces. At the same time, by providing a cross slot at one end of the worm 209, it is convenient for the staff to use tools, such as an electric screwdriver, to rotate the worm 209, thereby realizing the driving of the screw 204 and completing the adjustment of the height of the support mechanism 2. The operation is simple and convenient, and it adapts to the complex working environment of the mine.

[0042] Please see attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 6 With attached Figure 8The fixing mechanism 4 is located above the barrier 1, and serves to connect the surrounding rock with the supporting structure as a whole.

A special tool, such as an hexagonal electric wrench, can be used to rotate the screw 402 through the hexagonal hole 405, which facilitates installation and adjustment operations. A conical block 403 is provided at the upper end of the screw 402. When the screw 402 moves downward, the conical block 403 squeezes the expansion tube 401 to expand its outer diameter, thereby tightly squeezing with the hole wall at the top of the tunnel to generate friction, thereby realizing the firm fixation of the fixing mechanism 4 inside the tunnel hole. The outer side of the screw 402 is threadedly connected with the expansion tube 401, and the expansion tube 401 is expanded.

The display screen 6 is arranged on the outside of the arc plate 10, which is convenient for the staff to directly observe and obtain relevant data. A temperature and humidity sensor 7 and a vibration sensor 8 are arranged on the top of the arc plate 10. The temperature and humidity sensor 7 can monitor the temperature and humidity changes in the tunnel in real time, which is very important for understanding the environmental conditions of the tunnel. Through the monitoring of the temperature and humidity sensor 7, corresponding measures can be taken in time, such as adjusting the ventilation system, strengthening moisture-proof measures, etc., to ensure the safety and smooth progress of mine production. The vibration sensor 8 is used to monitor the vibration in the tunnel. The underground tunnel may be affected by various factors during the mining process and produce vibrations. , such as blasting operations, geological structure movements, etc., the vibration sensor 8 can capture these vibration signals in time and display them on the display screen 6. The staff can evaluate the stability of the tunnel and the stress condition of the support structure based on the amplitude and frequency of the vibration, and timely discover potential safety hazards and take corresponding reinforcement or adjustment measures.
