[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0041] like Figures 1 to 5 As shown, the present application provides a coal mine conveying system, which includes a tunnel 10, an isolation structure 20, a conveying assembly and a storage assembly 40. The isolation structure 20 is arranged in the tunnel 10, and the isolation structure 20 extends along the extension direction of the tunnel 10 to separate the tunnel 10 into a conveying channel 11 and a pedestrian channel 12. The conveying assembly is arranged in the conveying channel 11. The storage assembly 40 is used to store coal, and the storage assembly 40 has a discharge port 421, and the discharge port 421 is arranged corresponding to the conveying assembly.
[0042] By applying the technical solution of the present application, an isolation structure 20 is provided in the tunnel 10, and one side of the isolation structure 20 is the conveying channel 11, and the other side of the isolation structure 20 is the pedestrian channel 12. When a breach occurs, coal ore gushes out from the discharge port 421, and the breached coal ore is isolated and guided by the isolation structure 20, and flows to the conveying assembly without entering the pedestrian channel 12, thereby ensuring the safety of the staff and avoiding the occurrence of safety accidents. In addition, the provision of the isolation structure 20 not only improves safety, but also makes the space of the tunnel 10 more reasonably utilized. The conveying channel 11 is specifically used for coal mine transportation, while the pedestrian channel 12 ensures the safe passage of personnel and avoids the inefficiency and safety hazards caused by the mixed use of space.
[0043] In the present application, the conveying passage 11 and the pedestrian passage 12 can be ventilated separately.
[0044] like Figure 4 As shown, the isolation structure 20 includes an operating platform 21 and an isolation wall 22 .
[0045] The operating platform 21 is arranged in the tunnel 10, and the operating platform 21 is arranged horizontally. The two sides of the operating platform 21 are respectively abutted against the two sides of the tunnel 10. There is an operating chamber between the operating platform 21 and the top plate of the tunnel 10, and the operating chamber is connected with the pedestrian passage 12. A connecting hole is arranged on the operating platform 21, and the storage component 40 is passed through the connecting hole. The discharge port 421 is located below the operating platform 21.
[0046] The partition wall 22 extends along the extension direction of the tunnel 10, and the partition wall 22 is arranged around the outer periphery of the operating platform 21. The partition wall 22 cooperates with the operating platform 21 to separate the tunnel 10 into a conveying channel 11 and a pedestrian channel 12. In general, the staff generally moves in the pedestrian channel 12 and the operating chamber, that is, the pedestrian channel 12 and the operating chamber are the operating spaces for the staff.
[0047] Such a configuration makes it easy for the staff to operate and process the isolation structure 20 .
[0048] Optionally, the staff can perform anti-slip and anti-rust treatment on the surface of the isolation wall 22 .
[0049] Optionally, the isolation wall 22 can be made of steel plates, I-beams, square steels, etc. High-strength materials such as steel plates, I-beams, square steels, etc. can withstand the impact of coal mine collapse, ensure the structural stability and long-term reliability of the isolation wall 22, and reduce maintenance costs and times.
[0050] Specifically, the isolation wall 22 includes a first wall 221 , a second wall 222 and a third wall 223 .
[0051] The first wall 221 extends along the extension direction of the tunnel 10 . A fixing groove is provided on the top of the first wall 221 . The operating platform 21 is fixed in the fixing groove. The top of the first wall 221 abuts against the top plate of the tunnel 10 , and the bottom of the first wall 221 abuts against the bottom plate of the tunnel 10 .
[0052] The second wall 222 is arranged on one side of the operating platform 21, and the second wall 222 is located above the operating platform 21, and the second wall 222 is located on the side of the first wall 221 close to the conveying passage 11, one end of the second wall 222 abuts against the first wall 221, and the other end of the second wall 222 abuts against the side of the lane.
[0053] The third wall 223 is arranged on the other side of the operating platform 21, and the third wall 223 is located above the operating platform 21. The third wall 223 is located on the side of the first wall 221 close to the conveying passage 11. One end of the third wall 223 abuts against the first wall 221, and the other end of the third wall 223 abuts against the lane side.
[0054] In this way, by laying the first wall 221 along the extension direction of the tunnel 10, and arranging the second wall 222 and the third wall 223 above both sides of the operating platform 21, a closed protective structure is formed, which effectively isolates the staff working area from the conveying component area, greatly reduces the direct harm to the staff caused by coal splashing or gushing in the event of a bunker collapse, and enhances the safety of the staff.
[0055] In addition, the top of the first wall 221 abuts against the roof of the tunnel 10, and the bottom abuts against the bottom of the tunnel 10. This arrangement ensures the stability of the first wall 221. Even in extreme cases, such as the impact of a warehouse collapse, the integrity of the structure can be maintained, providing a long-lasting protective barrier for the staff.
[0056] The operating platform 21 is fixed in a fixing groove set on the top of the first wall 221, which not only ensures the stability of the operating platform 21, but also is closely combined with the isolation wall 22 to form a more stable operating platform 21, providing a safe working environment for the staff, especially in emergency situations such as warehouse collapse, which can effectively prevent the collapse of the operating platform 21 and ensure the safety of the staff.
[0057] The isolation wall 22 and the operating platform 21 are connected in a fixed or detachable manner.
[0058] Specifically, the staff can set the length of the first wall 221 according to the demand, so that the isolation structure 20 can store the coal ore that has collapsed.
[0059] Furthermore, the thickness of the isolation wall 22 is set between 200 mm and 300 mm.
[0060] In this arrangement, when the thickness of the isolation wall 22 is less than 200 mm, the strength of the isolation wall 22 is too low, and the isolation wall 22 is prone to collapse when a bunker collapse occurs; when the thickness of the isolation wall 22 is greater than 300 mm, it will lead to a waste of cost. Therefore, the thickness of the isolation wall 22 is set between 200 mm and 300 mm, so as to ensure that the isolation wall 22 has sufficient structural strength to withstand potential coal mine impacts and bunker collapse pressure. This thickness ensures that the isolation wall 22 can remain stable in the face of a bunker collapse, effectively block and guide the bursting coal mine, protect the pedestrian passage 12 and the operating chamber from being affected, and at the same time, under the premise of ensuring functional performance, it can reduce the amount of materials used and reduce construction costs and construction difficulties.
[0061] Optionally, the thickness of the isolation wall 22 can be set to 200 mm, 250 mm or 300 mm. In the present application, the thickness of the isolation wall 22 is set to 250 mm.
[0062] Among them, an observation hole and an operation hole are arranged on the isolation wall 22. A first shielding member is arranged at the observation hole, and the first shielding member can block or open the observation hole. A second shielding member is arranged at the operation hole, and the second shielding member can block or open the operation hole.
[0063] With such arrangement, through the control of the first shielding member and the second shielding member, the staff can open the observation hole or the operation hole when necessary to monitor the equipment and perform necessary operations. The observation hole and the operation hole enable the staff to complete the work tasks safely without being affected by the flow of the coal mine, thereby improving the flexibility and efficiency of the operation.
[0064] Furthermore, the first shielding member and the second shielding member are provided so that the observation hole and the operation hole can be blocked when not necessary, thereby reducing the risk of accidental spillage or splashing of coal into the pedestrian passage 12 and protecting the safety of the staff. In particular, in the event of an emergency such as a warehouse collapse, quickly closing the shielding member can effectively isolate the coal and prevent it from entering the operation space, thus providing a guarantee for emergency evacuation and safe operation.
[0065] Specifically, the top plate of the tunnel 10 is provided with a first groove, and the bottom plate of the tunnel 10 is provided with a second groove. Both the first groove and the second groove extend along the extension direction of the tunnel 10. The top of the first wall 221 is located in the first groove, and the bottom of the first wall 221 is located in the second groove.
[0066] Such an arrangement can significantly increase the structural stability of the first wall 221, prevent displacement or collapse when subjected to external force, and ensure the reliability and safety of the first wall 221 in emergency situations.
[0067] Furthermore, the top plate of the lane 10 is provided with a third slot and a fourth slot, the top of the second wall 222 is located in the third slot, and the top of the third wall 223 is located in the fourth slot. This arrangement can enhance the structural stability of the second wall 222 and the third wall 223.
[0068] like Figure 1 As shown, the storage assembly 40 includes a coal bunker 41 and a coal flow channel 42. The bottom of the coal bunker 41 has an outlet 411, and the coal bunker 41 is used to store coal. One end of the coal flow channel 42 is connected to the outlet 411, and the other end of the coal flow channel 42 has a discharge port 421, and the coal flow channel 42 is arranged in the connecting hole.
[0069] In this way, the outlet 411 at the bottom of the coal bunker 41 is closely connected to one end of the coal flow channel 42, ensuring that the coal can flow accurately from the coal bunker 41 to the conveying assembly. This direct connection reduces the loss of coal during transportation, improves the accuracy of coal transmission, and avoids unnecessary waste and additional cleaning work.
[0070] The top of the coal bunker 41 is provided with an inlet 413, and the inlet 413 can be communicated with the upper tunnel.
[0071] Among them, usually no staff passes or stays in the conveying channel 11. When staff are needed to enter, the coal discharge gate at the coal bunker 41 outlet 411 is closed, ensuring the safety of the staff during the bunker burst and eliminating safety hazards.
[0072] Specifically, the coal bunker 41 has a transition section 412 , which is communicated with the outlet 411 and is located above the outlet 411 . The inner diameter of the transition section 412 gradually decreases in a direction approaching the outlet 411 .
[0073] With such a configuration, the transition section 412 can effectively control the speed of the coal flow from the coal bunker 41 to the outlet 411. When the coal flow passes through the transition section 412, the coal flow speed will increase accordingly due to the gradual decrease in the cross-sectional area, but at the same time, this change in geometric shape helps to suppress the excessive turbulence of the coal flow, and can guide the coal mine to prevent the coal blocks from piling up at the outlet 411 or causing the conveying component to overload.
[0074] Furthermore, the storage assembly 40 also includes a coal feeder 43, which is disposed in the coal flow channel 42 to transport the coal from the outlet 411 to the discharge port 421, and the coal feeder 43 is located in the operating chamber.
[0075] In this way, the coal feeder 43 is located in the operating chamber, so that the staff can operate and monitor the equipment in a relatively closed and safe environment, avoiding the risk of direct exposure to the coal flow channel. In particular, in emergency situations such as the collapse of the coal bunker 41, the staff can wait for rescue or take emergency measures relatively safely in the chamber, reducing the risk of injury to the staff.
[0076] At the same time, the coal feeder 43 can ensure the smooth flow of coal in the mine.
[0077] The conveying assembly includes a conveyor 31 , which is disposed corresponding to the discharge port 421 , and extends along the extension direction of the conveying channel 11 .
[0078] In this way, the conveyor 31 can be used as an automated device to achieve continuous operation without being restricted by manual operation. The precise docking with the discharge port 421 makes the coal mine transportation process more automated, reduces the need for manual intervention, and improves the continuity and automation level of the operation.
