Description

Technical Field

[0001] The present invention relates to the technical field of coal bunker blockage clearing and treatment, and in particular to a coal bunker blockage clearing device and an operation method. Background Art

[0002] The height of existing vertical coal bunkers is generally in the range of 20m-30m; the cross-sectional area of ​​the coal bunker is 5-25m², the diameter of the circular section is 2.5-5m, the width of the arched section is about 3m, and the height is greater than 2m; the inclination angle of the inclined coal bunker is greater than or equal to 60°. The lower part of the coal bunker is generally a conical closing funnel, which can better reduce congestion. However, a common problem in production operation is that every winter or on rainy days, due to the humid weather, the raw coal bunker is often blocked, affecting the normal supply of coal. The coal bunker structure is as follows: Figure 1 shown.

[0003] Most coal mines still use the traditional manual cleaning method, such as Figure 1-2 Manual bunker cleaning doesn't require special equipment, but it's time-consuming and labor-intensive. The lack of ventilation in the bunker, harmful gases, and the large amounts of dust and other particulate matter created by the cleaning process can seriously harm workers' health. While working in the bunker, adhesives can sometimes fall and injure workers due to knocks and gravity.

[0004] Another solution is to install two electric vibrators on each coal bin. When there is a blockage, the coal can be loosened by vibration and fall down. This solution has a certain effect, but when the coal is very humid and has a high moisture content, it will stick to the wall and sometimes the more it is vibrated, the more solid it becomes, making it difficult to drop the coal.

[0005] Henan Polytechnic University has designed a vertical dredging equipment based on the technology of air cannon and the principle of dynamic high pressure. Figure 2 During the dredging process, the rubber bullets in the firing canister are accelerated by controlled high-pressure air and hit the coal in the coal bunker at high speed.

[0006] Air cannons are easy to operate and can be controlled manually, pneumatically, or electrically, individually or in groups. When using air cannons to clear the coal, the lower portion must be cleared first, followed by the upper portion, to facilitate coal removal. While air cannons significantly improve efficiency compared to manual clearing and relieve workers from high-intensity manual labor, they require a time-consuming energy storage process, resulting in low efficiency.

[0007] Most of the coal bunker blockage clearing solutions available on the market can remove the coal slag near the center of the coal bunker and make it slide out of the coal bunker. However, since the diameter of the coal bunker is as long as 2.5-5m, most of the existing treatment solutions are unable to solve the problem of coal slag accumulated on both sides of the coal bunker, causing the coal slag in the coal bunker to still accumulate on both sides of the coal bunker. Moreover, the force that can be generated by most of the existing coal bunker coal slag treatment solutions is unable to break up and drop the coal slag that has accumulated for a long time due to excessive viscosity, and cannot completely solve the blockage problem of the coal bunker. Summary of the Invention

[0008] Therefore, the technical problem to be solved by the present invention is to overcome the fact that most of the coal slag treatment solutions in the existing technology can generate forces that cannot break up and drop the coal slag accumulated for a long time due to excessive viscosity, and cannot completely solve the problem of coal bin blockage, thereby providing a coal bin clearing device and operating method.

[0009] In order to solve the above technical problems, the present invention provides a coal bunker blockage clearing device, comprising: a robot, the robot comprising an intermediate platform and an impact mechanism, moving mechanisms are provided on both sides of the intermediate platform, the moving mechanism comprises a pneumatic motor and a spiral propulsion mechanism, the pneumatic motor is connected to the spiral propulsion mechanism, the pneumatic motor is connected to the valve box in the intermediate platform, and the pneumatic motor is used to drive the spiral propulsion mechanism to move; the impact mechanism is arranged on the intermediate platform, and a pneumatic integrated component is provided on the impact mechanism, and the pneumatic integrated component comprises a pneumatic spear and an air cannon integrated into one piece; a lifting mechanism is provided on the coal bunker and is arranged close to the coal bunker entrance, an air compressor is provided in the lifting mechanism, and the pneumatic integrated component is connected to the air compressor; an observation mechanism is provided at the coal bunker entrance, and the observation mechanism is used to detect the internal situation of the coal bunker.

[0010] Furthermore, the impact mechanism includes a mechanical arm and a mechanical claw, the mechanical arm is rotatably arranged on the intermediate platform, the mechanical claw is arranged on the mechanical arm, and the mechanical claw is used to clamp the pneumatic integrated component.

[0011] Furthermore, the mechanical claw includes a base, a main body, and a clamping claw. The base is arranged at one end of the mechanical arm, the main body is arranged on the base, and the clamping claw is arranged on the main body. The clamping claw is used to clamp the pneumatic integrated component.

[0012] Furthermore, the pneumatic motor is connected to the valve box via a hose.

[0013] Furthermore, the lifting mechanism includes a lifting platform, a lifting device, and a driving member. The lifting device and the driving member are both arranged on the lifting platform. A lifting arm is provided at one end of the lifting device, and a steel cable is provided on the lifting arm. One end of the steel cable is connected to the driving member, and the other end is connected to the robot.

[0014] Furthermore, a clamp is provided at the other end of the steel cable, and the clamp is used to clamp the robot.

[0015] Furthermore, a fixed pulley is provided on the boom, and the steel cable is provided on the fixed pulley.

[0016] Furthermore, the driving member includes a motor and a drum, the motor is connected to the drum, and one end of the steel cable is wound around the drum.

[0017] Furthermore, the observation mechanism includes a depth camera and a fill light. The depth camera is used to obtain color images and depth images, detect coal slag accumulation, obstacle detection, distance measurement, and path planning and automatic control during robot operation. The observed data information is transmitted to the remote control system via WiFi.

[0018] The present invention also provides an operation method of the coal bunker blockage clearing device, comprising: a sling is arranged above the coal bunker entrance, a clamp is aligned with the coal bunker entrance, a robot is clamped with the clamp and aligned with the upper entrance of the coal bunker, a motor drives the steel cable to drop the robot clamped by the clamp onto the coal slag accumulated in the center of the coal bunker and then releases the clamp, an observation mechanism for observing downward is arranged at the coal bunker entrance, the observed data information is transmitted to the remote control system via WiFi, the computer of the external remote control system issues a command, the robot starts working, carries a pneumatic spear and walks to the coal slag accumulation blockage position, the robotic arm rotates and falls, so that the spear head of the pneumatic spear is against the surface of the blocked coal slag, the pneumatic spear starts working, the spear head of the pneumatic spear penetrates into the accumulated coal slag and impacts the coal slag, so that the accumulated The coal slag is crushed. If the viscosity of the coal slag is high due to excessive humidity and ordinary impact cannot crush the coal slag, an air cannon is used to release the impact gas to directly impact the accumulated coal slag, destroy the static friction between the coal slag, and restore the coal slag to a state of gravity sliding. The loosened coal slag flows out of the coal bunker along the conical inner wall at the bottom of the coal bunker. After the dredging work is completed, the user can directly pull the hose installed behind the pneumatic spear outside the coal bunker to make the pneumatic spear leave the coal bunker and realize the recovery of the pneumatic spear. After the robot transports the pneumatic spear to the coal slag pile, the external computer sends a command to make the robot return to the position under the clamp, so that the clamp re-clamps the robot, and the sling drives the steel cable to rise, and lifts the robot from the coal bunker entrance to realize the recovery of the robot.

[0019] The technical solution of the present invention has the following advantages:

[0020] The coal bunker blockage clearing device provided by the present invention includes: a robot, the robot includes an intermediate platform and an impact mechanism, moving mechanisms are provided on both sides of the intermediate platform, the moving mechanism includes a pneumatic motor and a spiral propulsion mechanism, the pneumatic motor is connected to the spiral propulsion mechanism, the pneumatic motor is connected to the valve box in the intermediate platform, and the pneumatic motor is used to drive the spiral propulsion mechanism to move; the impact mechanism is provided on the intermediate platform, and a pneumatic integrated component is provided on the impact mechanism, and the pneumatic integrated component includes a pneumatic spear and an air cannon integrated into one piece; a lifting mechanism is provided on the coal bunker and is arranged close to the coal bunker entrance, an air compressor is provided in the lifting mechanism, and the pneumatic integrated component is connected to the air compressor; an observation mechanism is provided at the coal bunker entrance, and the observation mechanism is used to detect the internal situation of the coal bunker.

[0021] A hoisting mechanism, located at the entrance to the coal bunker, facilitates the robot's transport to the interior of the bunker, where it can be used to clear accumulated coal slag. The robot comprises a central platform, a mobile mechanism located on either side of the platform, and an impact mechanism. A pneumatic motor within the mobile mechanism drives the rotation of a spiral propulsion mechanism, enabling the robot to navigate the complex coal bunker environment. Simultaneously, an observation mechanism is used to adaptively adjust the robot. The pneumatic assembly comprises a pneumatic spear and an air cannon, all integrated into one unit. Compressed air from an air compressor forces the pneumatic spear's piston to reciprocate, continuously impacting the spearhead, which squeezes the surrounding clogged coal slag and propels the spear forward. As the pneumatic spear advances, it can pull pipelines with smaller diameters into the coal slag, achieving deeper dredging. When conventional impact forces are unable to break or clear coal slag, the air cannon dredging device delivers a greater impact on the accumulated coal slag, clearing the clogged coal slag. The air cannon is powered by compressed gas. When it contacts accumulated coal slag, it suddenly releases the compressed gas through an air blast device, creating a powerful jet of air. The airflow can exceed the speed of sound, directly impacting the blocked area in the coal bunker. Because the compressed air creates a strong impact, this impact destroys the static friction between the coal slag, causing the stored material in the coal bunker to resume falling. The loosened coal slag flows out of the coal bunker along the tapered inner wall at the bottom of the coal bunker. Once the dredging work is completed, the user can directly pull the hose installed behind the pneumatic spear from outside the coal bunker to remove the pneumatic spear from the coal bunker and complete the recovery of the pneumatic spear. The robot transports the pneumatic spear to the coal slag pile and then uses the hoisting mechanism to lift the robot to the top of the coal bunker.

[0022] This coal bunker clearing device breaks up and drops coal slag that has accumulated for a long time due to excessive viscosity, completely resolving the problem of coal bunker blockage. It effectively clears the coal slag that has accumulated in the coal bunker, allowing it to be discharged smoothly, thus resolving the dangerous working environment in the coal bunker. Traditional methods cannot solve the problem of the two sides being too far from the center of the coal bunker. This device relieves workers from heavy physical labor and harsh working environments, protecting their lives and is also a key way to improve coal production and coal washing efficiency. It also features explosion-proof, dustproof, and waterproof features to ensure stable operation in harsh underground environments. Its automated operation improves the efficiency and safety of bunker clearing operations.

[0041] The preferred embodiments of the present disclosure are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0042] See also Figures 3 to 9 As shown, the present invention provides a coal bunker blockage clearing device, comprising: a robot 1, the robot 1 comprising an intermediate platform 2 and an impact mechanism 3, moving mechanisms 4 are provided on both sides of the intermediate platform 2, the moving mechanism 4 comprises a pneumatic motor 5 and a screw propulsion mechanism 6, the pneumatic motor 5 is connected to the screw propulsion mechanism 6, the pneumatic motor 5 is connected to the valve box 7 in the intermediate platform 2, and the pneumatic motor 5 is used to drive the screw propulsion mechanism 6 to move; the impact mechanism 3 is arranged on the intermediate platform 2, and a pneumatic integrated component 8 is provided on the impact mechanism 3, and the pneumatic integrated component 8 includes a pneumatic spear and an air cannon integrated into one piece; a hoisting mechanism 9 is provided on the coal bunker 10 and is arranged near the entrance of the coal bunker 10, an air compressor 11 is provided in the hoisting mechanism 9, and the pneumatic integrated component 8 is connected to the air compressor 11; an observation mechanism (not shown in the figure) is provided at the entrance of the coal bunker 10, and the observation mechanism is used to detect the internal situation of the coal bunker 10.

[0043] The hoisting mechanism 9, located at the entrance to the coal bunker 10, facilitates the transport of the robot 1 into the coal bunker 10. This facilitates the operation of the robot 1, thereby clearing the accumulated coal slag 12 in the coal bunker 10. The robot 1 comprises an intermediate platform 2, a moving mechanism 4 disposed on either side of the intermediate platform 2, and an impact mechanism 3. The pneumatic motor 5 within the moving mechanism 4 drives the rotation of the screw propulsion mechanism 6, enabling the robot 1 to navigate the complex environment of the coal bunker 10. At the same time, the robot 1 is adaptively adjusted in conjunction with the observation mechanism. Since the pneumatic assembly 8 includes a pneumatic spear and an air cannon integrated into one piece, the pneumatic spear, under the action of compressed air generated by the air compressor 11, causes the piston inside the pneumatic spear to reciprocate, continuously impacting the spear head, which squeezes the surrounding clogged coal slag 12 and drives the spear body forward. As the pneumatic spear advances, pipelines with a smaller diameter than the spear body can be brought into the coal slag 12 to achieve deeper dredging work. When encountering coal slag 12 that cannot be broken and dredged by conventional impact, the air cannon dredging device is used to achieve a greater impact on the accumulated coal slag 12, thereby dredging the clogged coal slag 12. The air cannon is powered by compressed gas. When the air cannon contacts the accumulated coal slag 12, the compressed gas is suddenly released through the air impact device, forming a strong jet of air. The air flow speed can exceed the speed of sound and directly impact the clogged area in the coal bin 10. Since the airflow formed by the compressed air has a great impact force, this impact destroys the static friction between the coal slag 12, causing the materials stored in the coal bin 10 to resume falling, and the loosened coal slag 12 flows out of the coal bin 10 along the conical inner wall at the bottom of the coal bin 10. After the dredging work is completed, the user can directly pull the hose 18 installed behind the pneumatic spear outside the coal bin 10 to make the pneumatic spear leave the coal bin 10 and realize the recovery of the pneumatic spear. The robot 1 transports the pneumatic spear to the pile of coal slag 12, and then uses the lifting mechanism 9 to lift the robot 1 to the top of the coal bin 10.

[0044] This coal bunker blockage clearing device breaks up and drops coal slag 12 that has accumulated for a long time due to excessive viscosity, completely resolving the problem of coal bunker blockage. It also clears the coal slag 12 accumulated in the coal bunker 10, allowing it to be smoothly discharged from the coal bunker 10, thereby resolving the dangerous working environment in the coal bunker 10. The device also relieves workers from heavy physical labor and harsh working environments, protecting their lives. It is also an important way to improve coal production and coal washing efficiency. It also features explosion-proof, dustproof, and waterproof features to ensure stable operation in harsh underground environments. Its automated operation improves the efficiency and safety of bunker clearing operations.
