Description

Technical Field

[0001] The utility model relates to the technical field of coal mining, in particular to a coal mining auxiliary tool based on accurate tunneling. Background Art

[0002] Coal-rich mining areas are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, it is generally chosen to dig tunnels underground to mine coal, which is an underground coal mine. When the coal seam is very close to the surface, it is generally chosen to directly strip the surface soil layer to mine coal, which is an open-pit coal mine. Most of the coal mines in my country are underground coal mines. The scope of coal mines includes a large area above and below the ground and related facilities. Coal mines are reasonable spaces excavated by humans when digging geological layers rich in coal, usually including tunnels, shafts, and mining faces. In traditional technologies, in order to ensure the accuracy of tunnel excavation, manual inspection is generally relied on by underground workers. In addition to the easy error that leads to inaccurate tunnel excavation, this situation is also accompanied by certain safety hazards, and it is urgently needed to be improved. Utility Model Content

[0003] The utility model provides a coal mining auxiliary tool based on accurate tunneling, which solves the above-mentioned technical problems.

[0004] The utility model solves the above-mentioned technical problems as follows:

[0005] A coal mining auxiliary tool based on precise tunnel excavation, comprising a plunger, a base, a laser rangefinder and a fixed column, wherein the bottom end of the base is provided with a plunger, the base is fixed in the tunnel by plugging the plunger, a groove is provided on the base, a fixed column is provided in the groove, a laser rangefinder is fixed on the fixed column, through holes are provided on the base and the fixed column, lasers of the laser rangefinders on the bases at both ends of the same axis pass through the through holes on the middle base to ensure the excavation direction, and the excavation distance is measured by the laser rangefinder.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, the base in the middle of the same axis is used to ensure the distance between the base and the tunnel wall by a laser distance measuring ruler.

[0008] The beneficial effects of adopting the above further scheme are:

[0009] Improved safety: Maintaining an appropriate distance between the base and the tunnel wall can effectively reduce the risk of accidents. In coal mining operations, if the base is too close to the tunnel wall, it may cause the base to get stuck or squeezed, which will affect the normal work and even cause equipment damage. The laser rangefinder ensures a safe distance from the tunnel wall, which helps to reduce these potential safety hazards.

[0010] Reduce human error: Traditionally, coal miners may need to rely on experience or manual measurement to determine the distance between the base and the tunnel wall. This is easily affected by subjective and environmental factors, resulting in inaccurate measurements or large errors. The use of laser distance measuring tape greatly reduces human errors and ensures the accuracy and reliability of data.

[0011] Save time and cost: With the laser distance meter, workers do not need to spend a lot of time on manual measurement, nor do they need to frequently adjust the position of the base to ensure a safe distance. This can save time and labor costs, and improve the efficiency and productivity of coal mining operations.

[0012] Real-time monitoring and adjustment: The laser rangefinder can provide real-time distance data, allowing workers to monitor the distance between the base and the tunnel wall at any time. Once the distance exceeds the preset range, the system may issue an alarm or reminder, and the worker can immediately adjust the position of the base to ensure safe operation.

[0013] Adapt to complex environment: The working environment of coal mines is often complex and changeable, including factors such as the shape of the tunnel and geological conditions. The laser rangefinder can flexibly adapt to different working environments and provide stable and reliable measurement data, so that workers can better cope with various challenges.

[0014] Improve coal mining accuracy: By maintaining the proper distance between the base and the tunnel wall, workers can more accurately control the position and direction of coal mining tools. This helps improve the accuracy of coal mining and avoid waste and unnecessary loss of resources.

[0015] Furthermore, the laser distance meter is mounted on the clamp, and the laser distance meter is mounted on the fixing columns of the bases at both ends through the clamp.

[0016] The beneficial effects of adopting the above further scheme are:

[0017] Stable and reliable: Vibration and environmental conditions at the coal mining site may affect the stability of the equipment. The clamp, as the mounting base of the laser rangefinder, can provide more stable support to ensure that the laser rangefinder will not shake or deviate during operation. This installation method can increase the reliability of the equipment and ensure the accuracy of data measurement.

[0018] Convenient installation and disassembly: The clamp serves as the middle piece between the laser distance meter and the base, making installation and disassembly easier. Workers only need to install the laser distance meter on the clamp and then clip the clamp to the fixed column without complicated tools or steps. This can save operation time and improve work efficiency.

[0019] Flexibility and adjustability: The design of the clamp allows the laser rangefinder to rotate and adjust its position relatively freely on the fixed column. In this way, workers can adjust the angle and direction of the laser rangefinder according to actual needs to obtain the best measurement results. This flexibility makes the tool more adaptable to different working situations and roadway structures.

[0020] Evenly distribute pressure: As a connecting device, the clamp can make the installation force of the laser distance meter more even. This can reduce the risk of damage to the laser distance meter caused by uneven force and extend the service life of the equipment.

[0021] Reduce vibration interference: Vibration and shock often exist in the working environment, which may affect the measurement accuracy of the laser rangefinder. By installing the clamp, the interference of external vibration on the laser rangefinder can be reduced, ensuring the stability and accuracy of the measurement data.

[0022] Space saving: As a connecting device, the clamp is usually designed to be very compact. This means that in narrow coal mining tunnels, the laser distance meter can still be easily installed without taking up too much space.

[0023] Furthermore, the clamp and the fixing column are provided with key teeth of matching sizes, and the clamp and the fixing column are limited by the engagement of the key teeth.

[0024] The beneficial effects of adopting the above further scheme are:

[0025] Stable connection: Key teeth are a very effective connection method that can provide strong connection force and stability. The key teeth design of the same size on the clamp and the fixing column allows them to mesh perfectly together to form a solid connection. This ensures that there will be no loosening or falling off during the working process, maintaining the stability of the equipment.

[0026] Prevent misalignment: The key teeth’s engagement limit design can effectively prevent the clamp and the fixing column from being misaligned during installation. Once the key teeth are engaged, they will automatically locate in the correct position without offset or mismatch, ensuring the accuracy of the connection.

[0027] Easy installation: The key design makes the installation of the clamp and the fixing column very easy. The worker only needs to insert the clamp into the fixing column, and the key will automatically engage and limit in the correct position. This is very convenient and quick to operate, eliminating complicated installation steps and tools.

[0028] Easy to disassemble: Although the key teeth provide a strong connection force, they can also be easily disassembled. Workers only need to apply appropriate force to remove the clamp from the fixed column. This design ensures a stable connection and convenience during maintenance and replacement of equipment.

[0029] Reduce wear: The engagement limit mode of the key teeth reduces the friction between the clamp and the fixed column to a minimum. This means that during long-term working, the key teeth will be less worn, extending the service life of the clamp and the fixed column.

[0030] Improved safety: Since the clamp and the fixed column are limited by the key teeth, the connection is very firm, thus reducing the risk of accidental loosening or falling off. This helps to improve the safety of work operations and avoid accidents caused by connection problems.

[0031] Furthermore, one end of the insertion rod away from the base is conical.

[0032] The beneficial effects of adopting the above further scheme are:

[0033] Convenient installation: The conical design makes the installation of the rod very easy. Workers only need to insert the conical rod end into the base without complicated tools or steps. This design saves operation time and improves work efficiency.

[0034] Stable fixation: The conical end of the rod can be better embedded in the base, forming a more stable fixation. This ensures that the rod will not shake or shift during operation, maintaining the stability of the equipment.

[0035] Prevent rotation or sliding: The conical end of the plunger can better lock into the base, preventing the plunger from rotating or sliding during use. This ensures that the plunger remains in the desired position and will not affect the working effect due to accidental movement.

[0036] Adapts to different angles: The conical design allows the plunger to more easily adapt to bases of different angles and curvatures. In narrow environments such as coal mine tunnels, the shape and angle of the base may vary, and the conical plunger can more flexibly adapt to these changes.

[0037] Reduce friction: The end of the plug away from the base is conical, and it gradually tapers from large to small when inserted, reducing the friction between the plug and the base. This helps reduce wear on the plug and makes insertion and removal smoother.

[0038] Space saving: The conical plunger design allows for more efficient use of space in confined spaces. In narrow environments such as coal mine tunnels, space is often limited, so this design ensures that the plunger can be easily installed and takes up minimal space.

[0039] The beneficial effects of the utility model are:

[0040] Precise positioning and accurate direction of excavation: The design of this tool enables accurate positioning and accurate control of the excavation direction when performing coal mining operations in the tunnel. Through the combination of the laser distance meter and the fixed column, the worker can accurately measure the distance between the tool and the tunnel wall. This ensures that the tool can always remain in the predetermined position during coal mining operations, avoiding errors and deviations. The laser distance meter is mounted on the base, and through the through hole in the base, the laser can pass through the through hole in the middle base. This design ensures that the transmission path of the laser is straight and stable, thereby ensuring the accuracy of the excavation direction. Workers can accurately control the movement and direction of the coal mining tool according to the instructions of the laser, avoiding unnecessary corrections and adjustments.

[0041] Measuring the excavation distance and work efficiency: The installation of laser distance measuring tape allows workers to measure the excavation distance of coal mining tools in real time. This is crucial for optimizing work planning and production efficiency. Workers can make adjustments and plans based on the actual excavation distance to ensure that the entire coal mining process proceeds at the expected pace. This not only improves work efficiency, but also reduces the waste of energy and resources.

[0042] Equipment stability and safety: The design of the tool takes into account the importance of stable fixation in the tunnel. The end of the rod away from the base is conical, which makes it easy to plug and fix the rod on the base, ensuring the stability of the entire tool. In addition, there is a groove on the base, and a fixing column is set in the groove, and the laser distance ruler is fixed on the fixing column. This structure allows the laser distance ruler to be firmly installed on the tool, and it will not fall off or lose alignment due to vibration or movement during work.

[0043] Easy installation and removal: The tool's clamp and fixed column are equipped with key teeth of matching size, which makes the installation and removal of the tool more convenient and quick. Workers can easily install the laser rangefinder on the fixed column, or remove it for maintenance and replacement when necessary. This design saves the operator's time and energy, and also ensures the convenience of the tool when used on site.

[0044] Improved operation quality and efficiency: Overall, this coal mining auxiliary tool based on precise tunneling not only improves the precision and accuracy of coal mining operations, but also improves the quality and efficiency of operations. Workers can focus more on their work without worrying about position deviation or inaccurate tunneling direction. At the same time, real-time tunneling distance measurement and precise positioning control make the entire coal mining process smoother and more efficient.

[0054] Embodiment 1

[0055] A coal mining auxiliary tool based on accurate tunnel excavation includes a plunger 1, a base 2, a laser rangefinder 6 and a fixed column 7. The bottom end of the base 2 is provided with a plunger 1, and the end of the plunger 1 away from the base 2 is conical. The conical design makes the installation of the plunger 1 very simple. Workers only need to insert the conical end of the plunger 1 into the base 2 without complicated tools or steps. This design saves operation time and improves work efficiency. The conical end of the plunger 1 can be better embedded in the base 2 to form a more stable fixation. This ensures that the plunger 1 will not shake or shift during work, and maintains the stability of the equipment. The conical end of the plunger 1 can be better locked in the base 2, preventing the plunger 1 from rotating or sliding during use. This ensures that the plunger 1 remains in the desired position and does not affect the work effect due to accidental movement. The conical design allows the plunger 1 to more easily adapt to bases 2 with different angles and curvatures. In narrow environments such as coal mine tunnels, the shape and angle of the base 2 may change, and the conical plug rod 1 can adapt to these changes more flexibly. The end of the plug rod 1 away from the base 2 is conical, and gradually tapers from large to small when inserted, reducing the friction between the base 2. This helps to reduce the wear of the plug rod 1 and makes insertion and removal smoother. The conical plug rod 1 design can make more effective use of space in a limited space. In narrow environments such as coal mine tunnels, space is usually very limited, so this design can ensure that the plug rod 1 can be easily installed and occupy the smallest space. The base 2 is fixed in the tunnel by plugging the plug rod 1. A groove 5 is opened on the base 2, and a fixed column 7 is provided in the groove 5. A laser rangefinder 6 is fixed on the fixed column 7. The laser rangefinder 6 is installed on the clamp 4. The laser rangefinder 6 is installed on the fixed column 7 of the base 2 at both ends through the clamp 4. The vibration and environmental conditions at the coal mining site may affect the stability of the equipment. As the mounting base of the laser rangefinder 6, the hoop 4 can provide more stable support to ensure that the laser rangefinder 6 will not shake or deflect during operation. This installation method can increase the reliability of the equipment and ensure the accuracy of data measurement. As an intermediate piece connecting the laser rangefinder 6 and the base 2, the hoop 4 makes installation and disassembly easier. Workers only need to install the laser rangefinder 6 on the hoop 4, and then clip the hoop 4 to the fixed column 7, without complicated tools or steps. This can save operation time and improve work efficiency. The design of the hoop 4 allows the laser rangefinder 6 to rotate and adjust its position relatively freely on the fixed column 7. In this way, workers can adjust the angle and direction of the laser rangefinder 6 according to actual needs to obtain the best measurement effect. This flexibility makes the tool more adaptable to different working conditions and lane structures. As a connecting device, the hoop 4 can make the installation force of the laser rangefinder 6 more uniform. This can reduce the risk of damage to the laser rangefinder 6 caused by uneven force and extend the service life of the equipment.There are often vibrations and shocks in the working environment, which may affect the measurement accuracy of the laser rangefinder 6. Through the installation method of the clamp 4, the interference of external vibration on the laser rangefinder 6 can be reduced, ensuring the stability and accuracy of the measurement data. As a connecting device, the clamp 4 is usually designed to be very compact. This means that in narrow coal mining tunnels, the laser rangefinder 6 can still be easily installed without taking up too much space. The clamp 4 and the fixed column 7 are provided with key teeth of matching size. The clamp 4 and the fixed column 7 are limited by the engagement of the key teeth. The key teeth are a very effective connection method that can provide strong connection force and stability. The key teeth design of matching size on the clamp 4 and the fixed column 7 allows them to mesh perfectly together to form a solid connection. This ensures that there will be no loosening or falling off during the working process, and maintains the stability of the equipment. The engagement limit design of the key teeth can effectively prevent the clamp 4 and the fixed column 7 from being misaligned during the installation process. Once the key teeth are engaged, they will automatically be positioned in the correct position without offset or mismatch, ensuring the accuracy of the connection. The design of the key teeth makes the installation of the clamp 4 and the fixed column 7 very easy. The worker only needs to insert the clamp 4 into the fixed column 7, and the key teeth will automatically engage and limit in the correct position. This is very convenient and quick to operate, eliminating complicated installation steps and tools. Although the key teeth provide a strong connection force, they can also be easily disassembled. The worker only needs to apply appropriate force to remove the clamp 4 from the fixed column 7. This design ensures both a stable connection and convenience during maintenance and replacement of equipment. The engagement and limiting mode of the key teeth reduces the friction between the clamp 4 and the fixed column 7 to a minimum. This means that during long-term work, the degree of wear of the key teeth is small, which prolongs the service life of the clamp 4 and the fixed column 7. Since the clamp 4 and the fixed column 7 are limited by the engagement of the key teeth, the connection is very firm, thereby reducing the risk of accidental loosening or falling off. This helps to improve the safety of work operations and avoid accidents caused by connection problems. Through holes 3 are provided on the base 2 and the fixed column 7. The laser of the laser rangefinder 6 on the bases 2 at both ends of the same axis passes through the through hole 3 on the middle base 2 to ensure the accuracy of the excavation direction. At the same time, the excavation distance is measured by the laser rangefinder 6. The base 2 in the middle of the same axis uses the laser rangefinder 6 to ensure the distance between the base 2 and the tunnel wall. Keeping the appropriate distance between the base 2 and the tunnel wall can effectively reduce the risk of accidents. In coal mining operations, if the base 2 is too close to the tunnel wall, it may cause the base 2 to get stuck or squeezed, thereby affecting the normal progress of the work and even causing equipment damage. The laser rangefinder 6 ensures a safe distance from the tunnel wall, which helps to reduce these potential safety hazards. Traditionally, coal miners may need to rely on experience or manual measurement to determine the distance between the base 2 and the tunnel wall. This is easily affected by subjective factors and environmental factors, resulting in inaccurate measurements or large errors.The use of the laser rangefinder 6 greatly reduces human errors and ensures the accuracy and reliability of the data.

This can save time and labor costs and improve the efficiency and productivity of coal mining operations. The laser rangefinder 6 can provide real-time distance data, allowing workers to monitor the distance between the base 2 and the tunnel wall at any time. Once the distance exceeds the predetermined range, the system may issue an alarm or reminder, and the worker can immediately adjust the position of the base 2 to ensure safe operation. The working environment of coal mines is often complex and changeable, including factors such as the shape of the tunnel and geological conditions. The laser rangefinder 6 can flexibly adapt to different working environments and provide stable and reliable measurement data, allowing workers to better cope with various challenges. By maintaining the appropriate distance between the base 2 and the tunnel wall, workers can more accurately control the position and direction of coal mining tools. This helps to improve the accuracy of coal mining and avoid waste and unnecessary loss of resources.
