Description

Technical Field

[0001] This utility model belongs to the field of mine safety protection technology, and specifically relates to a mine protection device. Background Technology

[0002] During mining operations (such as coal mines and metal mines), processes like drilling and blasting generate significant amounts of dust and impact loads, necessitating the installation of protective equipment around the perimeter. Existing mine safety barriers are primarily fixed to the ground with screws, and their structures include gantry frames and simple railings. During blasting, vibrations can easily loosen the screws, reducing the barrier's stability and rendering it ineffective in mitigating ground vibrations caused by blasting. The protective effect is poor, and shock absorption relies on single springs or rubber pads, which are insufficient for intercepting and absorbing blast debris or shock waves, threatening personnel safety. Frequent maintenance and replacement of screws and shock-absorbing components, coupled with the time-consuming and labor-intensive process of drilling for installation, increase both labor and material costs. Utility Model Content

[0003] In view of some or all of the above-mentioned technical problems existing in the prior art, this utility model proposes a mine protection device. By combining a dynamic plug-in with a buffer mechanism, the protection device achieves high stability and impact resistance. When subjected to impact, the buffer part rotates to drive the plug-in to penetrate deeper into the ground for enhanced fixation, which helps to improve the stability and ease of installation of the mine protection device, avoids structural loosening caused by vibration, and further enhances the protective effect and impact resistance through the shock absorption mechanism of the buffer mechanism, thus ensuring personnel safety.

[0004] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is as follows:

[0005] A mine safety device includes an installation section, a buffer section, a force-bearing section, and a buffer mechanism; wherein,

[0006] The buffer section is rotatably disposed within the mounting section about the horizontal direction, and a plug extending in the vertical direction is provided on one side of the buffer section.

[0007] The force-receiving part is located on the other side of the buffer part, and a buffer mechanism is provided between the force-receiving part and the buffer part;

[0008] When the outer side of the force-bearing part is subjected to an impact force, it drives the buffer part to rotate, thereby causing the plug-in to move vertically downward.

[0009] The above technical solution can be further improved as described below.

[0010] In one embodiment, the mounting part includes a gantry frame and a mounting housing, wherein the mounting housing is a frame formed by sequentially connecting three adjacent sides, and the frame is located at the bottom of the gantry frame.

[0011] In one embodiment, the buffer part is a buffer plate, and the bottom of the buffer plate is rotatably disposed at the bottom of the portal frame in a horizontal direction.

[0012] In one embodiment, a support member is further included, the two ends of which are respectively hinged to the buffer plate and the plug in a horizontal direction, so that when the buffer plate is subjected to an impact force, it rotates to actuate the support member and thus drive the plug.

[0013] In one embodiment, the buffer mechanism includes an airbag disposed between the buffer plate and the force-bearing part, the airbag is connected to an air pump, the air pump passes through the buffer plate, and the support member is provided with an air pump button on the side near the buffer plate for abutting the air pump.

[0018] In one embodiment, a dustproof net is detachably provided on the top of the mounting portion.

[0019] Compared with the prior art, the advantages of this utility model include at least the following:

[0020] 1. Improved stability: The dynamic fixing method of the plug replaces the traditional screw, which automatically penetrates into the ground upon impact, significantly enhancing the vibration resistance. The rotation of the buffer part drives the plug to insert into the ground, and the design of "converting impact energy into fixing force" simultaneously achieves shock absorption and stability.

[0021] 2. Graded trigger shock absorption: Through the mechanical linkage between the support components and the air pump button, different levels of impact are distinguished, and secondary shock absorption is automatically activated to avoid energy waste;

[0022] 3. Multi-level shock absorption and high-efficiency protection: The elastic support component that abuts against the installation part in the vertical direction is combined with the airbag and shock-absorbing spring to achieve dual shock absorption of "mechanical buffering + pneumatic buffering". It can repeatedly absorb impact energy and the protection efficiency is greatly improved compared with the existing technology.

[0023] 4. Safety Guarantee: The impact-bearing part and shock-absorbing pads disperse the impact force, and the airbag expands to form a flexible barrier, reducing the risk of injury from flying debris and ensuring personnel safety. Attached Figure Description

[0029] To make the technical solution and advantages of this utility model clearer, the exemplary embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not an exhaustive list of all embodiments. Furthermore, without conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0030] like Figures 1 to 3 As shown, the mine protection device 100 of this application embodiment includes an installation part 11, a buffer part 12, a force-bearing part 13, and a buffer mechanism 14. The buffer part 12 is rotatably disposed within the installation part 11 in a horizontal direction, for example, by a pin hinge to allow the buffer part 12 to rotate around the bottom end of the installation part 11. An insert 15 is provided on one side of the buffer part 12. The force-bearing part 13 is disposed on the other side of the buffer part 12, and a buffer mechanism 14 is provided between the force-bearing part 13 and the buffer part 12. When the outer side of the force-bearing part 13 is subjected to an impact force, it drives the buffer part 12 to rotate so that the insert 15 can be inserted into the ground. Specifically, in this embodiment, the inserts 15 are arranged at intervals along the horizontal direction in the buffer part 12.

[0031] Clearly, the mine protection device proposed in this embodiment of the invention achieves high stability and impact resistance by combining the dynamic plug-in 15 with the buffer mechanism 14. When subjected to impact, the buffer part 12 rotates, driving the plug-in 15 to penetrate deeper into the ground for enhanced fixation. This improves the stability and ease of installation of the mine protection device, preventing structural loosening due to vibration. Furthermore, the shock absorption mechanism of the buffer mechanism 14 further enhances the protective effect, strengthens impact resistance, and ensures personnel safety. By further spacing multiple sets of plug-ins 15 inserted into the ground, the installation stability of the mine protection device can be greatly improved.

[0032] like Figure 2 and Figure 3 As shown, specifically in this embodiment, the mounting part 11 includes a portal frame 112 and a mounting housing 114. The mounting housing 114 is a frame formed by sequentially connecting three adjacent sides, and the frame is located at the bottom of the portal frame 112. Figure 2 As shown, in this embodiment, the buffer part 12 is a buffer plate, and the bottom of the buffer plate is rotatably disposed at the bottom of the gantry frame 112 in the horizontal direction. Specifically, the mounting part 11, which cooperates with the gantry frame 112 and the mounting housing 114 of the frame structure, can install the rotating buffer plate very conveniently, and facilitates the insertion of the plug 15 to the ground between the inner side of the frame and the gantry frame. The structure is simple, compact, stable and reliable, and easy to install and arrange.

[0033] like Figure 2 and Figure 3 As shown, specifically in this embodiment, the mine protection device 100 further includes a support member 16. Both ends of the support member 16 are horizontally hinged to a buffer plate and a plug-in 15 via U-shaped members 161, respectively. This allows the buffer plate to rotate when subjected to impact force, applying force to the support member 16 and driving the plug-in 15 to insert into the ground. Specifically, the plug-in 15, through the hinged support member 16, achieves vertical insertion into the ground under the rotational drive of the buffer plate, greatly ensuring the stable and reliable insertion of the plug-in 15 into the ground, thereby significantly improving the stability and reliability of the mine protection device installation.

[0034] like Figure 1 and Figure 2 As shown, specifically in this embodiment, the buffer mechanism 14 includes an airbag 141 disposed between the buffer plate and the force-bearing part 13. The airbag 141 is connected to an air pump 142, which passes through the buffer plate. An air pump button 143 for abutting the air pump 142 is provided on the inner side of the support member 16, i.e., the side near the buffer plate. The airbag 141 is preferably a square airbag. It is easy to understand that in this embodiment, through the mechanical linkage between the support member 16 and the air pump button 143, different intensity impacts are distinguished, the secondary shock absorption is automatically activated, and the shock absorption is triggered in stages to avoid energy waste.

[0035] like Figure 2 and Figure 3 As shown, specifically in this embodiment, the plug-in 15 is a square plug rod, and the inner side of the mounting housing 114 is provided with a positioning structure 20. Specifically, the positioning structure 20 is a square positioning frame formed by connecting three adjacent sides in sequence. The two sides of the square positioning frame and the inner side of the mounting housing 114 frame enclose a square positioning space, and the square plug rod is slidably disposed in the positioning space in the vertical direction. Further, in this embodiment, the bottom of the plug rod is provided with a trumpet-shaped ground cone 17. It is easy to understand that in this embodiment, by cooperating with the square plug rod and the square positioning frame, the stability and reliability of the protective device installation can be further improved, and the setting of the trumpet-shaped ground cone 17 can greatly improve the convenience and stability of the plug-in 15 being inserted into the ground.

[0036] In an embodiment not shown, the plug 15 readily understands that includes a helical anchor and a rotary drive structure for driving the helical anchor to rotate and extend. By using a dynamic fixing method with a helical anchor instead of traditional screws, the design of "converting impact energy into fixing force" can be achieved simultaneously, realizing shock absorption and stability, as well as ease of installation.

[0037] like Figure 2 and Figure 3 As shown, specifically in this embodiment, the top of the square insert is provided with a limiting part 18. Specifically, the limiting part 18 is a plate-like structure, and the bottom of the limiting part 18 is provided with an elastic support member 19 for abutting against the top of the mounting housing 114 in the mounting part 11 in the vertical direction. Preferably, the elastic support member 19 is fixedly connected to the top of the mounting housing 114. Preferably, the elastic support member 19 is a compression spring structure. Clearly, the elastic support member 19 and the air pump airbag achieve dual shock absorption, greatly improving the protective effect.

[0038] like Figure 1 and Figure 4 As shown, specifically in this embodiment, the buffer mechanism 14 further includes a shock-absorbing spring 144 and / or a hydraulic damper disposed between the force-bearing part 13 and the buffer part 12, and a shock-absorbing plate 145 disposed on the outer surface of the force-bearing part 13, with at least three sets of shock-absorbing plates 145. Specifically, the hydraulic damper can replace the combination of the airbag 141 and the shock-absorbing spring 144, achieving buffering through liquid compression, but the response speed is relatively slow, suitable for low-frequency, high-intensity impact scenarios. Alternatively, the hydraulic damper can not replace the airbag 141, but can instead form a more stable and reliable buffer mechanism 14 together with the airbag 141, the shock-absorbing spring 144, and the shock-absorbing plate 145, resulting in a significantly improved buffering and shock absorption effect.

[0039] In an embodiment not shown, a dustproof net is detachably provided on the top of the mounting part 11. Specifically, a detachable dustproof net can be added to the top of the gantry frame 112, which is connected to the gantry frame 112 by a buckle to meet dust protection requirements without affecting the original shock absorption function.

[0040] In an embodiment not shown, the force-bearing part 13 is equipped with a pressure monitoring device and a wireless data transmission module electrically connected to the pressure monitoring device. Specifically, the pressure monitoring device is preferably a pressure sensor, and the force-bearing part 13 is preferably a force-bearing plate, which has a simple structure, low manufacturing cost, and large force-bearing area. To achieve intelligent monitoring upgrade of the mine protection device 100, a pressure sensor and a wireless data transmission module integrated into the force-bearing plate can be added to monitor the impact load in real time and send early warning signals to the central control system to achieve preventive maintenance.

[0041] The working principle of the mine protection device in this application embodiment is as follows:

[0042] Initial impact stage: When an external object impacts the force-bearing part 13, the shock-absorbing spring 144 and the shock-absorbing plate 145 provide initial buffering. The buffer part 12 rotates backward around the pin axis, pushing the support 16 to drive the plug 15 to descend. The elastic support 19 is compressed and stores energy, achieving first-level shock absorption. At the same time, the ground cone 17 inserts into a deeper soil layer to enhance stability.

[0043] High-intensity impact stage: If the impact force is too large, the buffer part 12 rotates to make the support part 16 press the air pump button 143, the air pump 142 inflates the air bag 141, and the air bag 141 pushes the force-bearing part 13 to counteract the impact energy in the opposite direction, thus achieving secondary shock absorption.

[0044] The plug-in 15 and the buffer part 12 are hinged through the support member 16 to form a "rotation-sliding" linkage mechanism;

[0045] The air pump button 143 is linked to the support 16, and the secondary damping is triggered only when the impact force exceeds the primary damping threshold.

[0046] As can be seen from the above embodiments, the mine protection device of this utility model achieves high stability and impact resistance by combining dynamic plug-in with buffer mechanism. When impacted, the buffer part rotates to drive the plug-in to penetrate deeper into the ground for enhanced fixation, which helps to improve the stability and ease of installation of the mine protection device, avoid structural loosening caused by vibration, and further enhance the protection effect and impact resistance through the shock absorption mechanism of the buffer mechanism, thus ensuring personnel safety.
