[0004] In the existing technology, although supports are installed on the left and right sides of the protective plate to provide support, in actual application, the butt joint between the set structures still needs to be connected using tools, which makes the installation process cumbersome and time-consuming, thereby affecting the maintenance efficiency, and the side end design of the protective plate is easily impacted by splashing ore, further reducing its service life.

[0005] In response to the above problems, there is an urgent need for innovative design based on the existing energy-saving mine safety protection devices. Therefore, this application proposes an energy-saving mine safety protection device to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an energy-saving mine safety protection device to solve the problems mentioned in the background art. Currently, the market has installed brackets on the left and right sides of the guard plate to provide support. However, in actual applications, the connection between the structures still requires the use of tools, which makes the installation process cumbersome and time-consuming, thus affecting maintenance efficiency. Furthermore, the side design of the guard plate is easily affected by the impact of splashed ore, which further reduces its service life.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving mine safety protection device, comprising a support column, a protective plate connected to the surface of the support column via a buffer assembly, a snap-fit ​​assembly installed on the top of the support column, the snap-fit ​​assembly including a support rod installed on the support column, a limiting ladder block installed on the top of the support rod, an auxiliary ladder block sleeved on the outside of the support rod, the limiting ladder block being a ladder shape that is narrower at the top and wider at the bottom, the auxiliary ladder block being a ladder shape that is wider at the top and narrower at the bottom, a fence assembly installed on the side end of the support column, the fence assembly including a support frame installed on the side end of the support column, a limiting horizontal plate installed on the upper end of the support frame, a limiting assembly provided inside the limiting horizontal plate, the limiting assembly including an inclined snap-fit ​​block installed inside the limiting horizontal plate.

[0008] Preferably, the limiting horizontal plate has a storage cavity inside, and a moving rod is transversely arranged inside the limiting horizontal plate, the moving space of the moving rod being connected to the storage cavity.

[0009] Preferably, an auxiliary spring is sleeved on the outer side of the moving rod, the moving rod is symmetrically arranged about the vertical central axis of the limiting ladder block, and an inclined locking block is installed on the opposite side of the moving rod.

[0010] Preferably, the buffer assembly includes a buffer element, the buffer element includes a telescopic structure, and a buffer spring is sleeved on the outside of the telescopic structure. The side end of the buffer element is connected to an external fluid delivery system through an air supply element.

[0011] Preferably, the support frame has a metal steel bar cross structure inside, a cover plate is connected to the surface of the support frame, and a protective seat is connected to the side surface of the cover plate through a buffer assembly.

[0012] Preferably, the protective seat has a buffer seat inside, the buffer seat has a storage slot inside, and the storage slot has an air box inside. Two adjacent air boxes are connected by a conveying pipe, and the conveying pipe is connected to an external fluid conveying system.

[0013] Preferably, a support assembly is provided on the back of the support frame. The support assembly includes a cross frame installed on the back of the support frame. A movable rod is connected to the cross frame through a first rotating seat. The movable rod has a snap-fit ​​hole.

[0014] Preferably, a sleeve is movably connected to the bottom end of the movable rod, and the movable rod and the sleeve are fixedly connected by a fixing bolt passing through the snap-fit ​​hole. A movable plate is connected to the bottom end of the sleeve through a second rotating seat.

[0015] Preferably, a guide wheel is installed under the movable plate, a support platform is provided on the side of the cross frame, a guide groove with a U-shaped longitudinal section is opened on the upper end of the support platform, and the guide groove is used to provide movement for the guide wheel. A locking member for limiting is provided inside the guide wheel, a locking groove adapted to the locking member is opened on the support platform, a cushioning material is installed on the back of the support frame, and a counterweight box is installed inside the support platform.

[0016] Compared with existing technologies, the beneficial effects of this invention are as follows: This energy-saving mine safety protection device, by having an inclined locking block engage with the bottom of the limiting ladder block, quickly fixes the support column and support frame. The overall installation is quick and convenient, reducing the inconvenience caused by the need for tools, significantly shortening installation time, and lowering labor costs. The overall structure is simple, solving the problem of increased transportation costs caused by complex structures, and improving the service life and resource utilization of the equipment. The specific details are as follows: (1) Through the snap-fit ​​design of the support column and the fence component, the quick docking installation is realized. The snap-fit ​​component at the top of the support column allows the fence to be flexibly adjusted according to the varied spatial layout of the coal mine. It can be fixed without relying on tools, which greatly improves the adaptability and efficiency of installation in complex coal mine environments and significantly saves energy consumption during the installation stage.

[0017] (2) The structure adopts a convenient disassembly mechanism. When disassembling, you only need to press down on the support frame and use the upper wide and lower narrow structure of the auxiliary ladder block to push the inclined block to compress the spring and disengage from the limit ladder block. This solves the problem of inconvenient inspection and maintenance of traditional equipment. You can inspect and maintain the equipment without complicated operations, reduce resource waste and realize resource recycling.

[0018] (3) When the protective plate is impacted, the buffer spring first absorbs the primary impact force, the buffer component is linked with the external fluid delivery system to further dissipate energy, the cross structure of the metal steel bars in the support frame enhances the impact resistance, and when the surface protective seat is impacted, the air box expands rapidly and works with the buffer component to absorb the secondary impact force, greatly improving the protection capability.

[0019] (4) Through the combined design of cross frame, movable rod and sleeve, the support angle can be flexibly adjusted. The movable rod can slide in the sleeve. The length can be locked by passing through different snap-fit ​​holes with the help of the fixing bolt. The guide wheel at the bottom of the moving plate can be finely adjusted to ensure the stability of the diagonal brace. After the angle is determined, the snap-fit ​​locks the guide wheel to prevent displacement, which improves the adaptability to the complex environment downhole and further optimizes the energy consumption of transportation and storage.

[0020] The counterweight box inside the support platform increases the weight at the bottom, significantly improving the overall anti-overturning ability and reducing the risk of accidents caused by equipment tipping over. The stable connection of the snap-fit ​​components and the locking mechanism of the guide wheels ensure that the structure remains stable in the complex downhole environment, avoids accidental displacement, and improves the safety of the working environment.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1: In this example, the tilting block 13 engages with the bottom of the limiting ladder block 7, quickly fixing the support column 1 to the support frame 9. The overall installation is quick and convenient, reducing the inconvenience caused by requiring tools for installation. Figures 1-9The technical solution shown includes a support column 1, with a protective plate 5 connected to the surface of the support column 1 via a buffer assembly. A snap-fit ​​assembly is installed on the top of the support column 1, including a support rod 6 mounted on the support column 1. A limiting ladder block 7 is installed on the top of the support rod 6, and an auxiliary ladder block 8 is fitted around the outside of the support rod 6. The limiting ladder block 7 is narrower at the top and wider at the bottom, while the auxiliary ladder block 8 is wider at the top and narrower at the bottom. A fence assembly is installed on the side of the support column 1, including a support frame 9 installed on the side of the support column 1. A limiting horizontal plate 901 is installed on the upper end of the support frame 9, and a limiting component is provided inside the limiting horizontal plate 901. The limiting component includes an inclined snap-fit ​​block 13 installed inside the limiting horizontal plate 901. The plate 901 has a storage cavity 10 inside. A moving rod 11 is horizontally installed through the limiting horizontal plate 901. The moving space of the moving rod 11 is connected to the storage cavity 10. An auxiliary spring 12 is sleeved on the outside of the moving rod 11. The moving rod 11 is symmetrically arranged about the vertical central axis of the limiting ladder block 7. An inclined locking block 13 is installed on the opposite side of the moving rod 11. The support column 1 is fixed to the ground, providing a vertical fixed foundation for the overall structure. Its top end is quickly connected to the fence assembly through a snap-fit ​​component, which facilitates layout and installation according to the coal mine environment, effectively improving installation flexibility and adapting to the complex and ever-changing spatial layout requirements of underground coal mines. The limiting horizontal plate 901 at the upper end of the support frame 9 of the fence assembly has a built-in limiting component, and the moving rod 11 inside the storage cavity 10... Auxiliary spring 12 is fitted onto rod 11, and tilting blocks 13 are installed on the opposite side. During connection, the limiting horizontal plate 901 is clamped onto the limiting ladder block 7. At this time, the tilting blocks 13 inside the limiting horizontal plate 901 move down from the top of the limiting ladder block 7 with the help of the tilting surface. Under the elastic reset action of the auxiliary spring 12, the tilting blocks 13 are clamped into the bottom of the limiting ladder block 7, completing the quick fixation of the support column 1 and the support frame 9. The overall installation is quick and convenient, reducing the inconvenience caused by the need for tools, greatly shortening the installation time, and reducing labor costs. The overall structure is simple, solving the problem of increased transportation costs caused by complex structures. When disassembly is required, the limiting horizontal plate 901 is pressed down, causing the tilting blocks 13 to move to the auxiliary ladder block 7. At the bottom of platform 8, since the auxiliary ladder platform 8, which is fitted on the outside of the support rod 6, is wider at the top and narrower at the bottom, when the support frame 9 is moved upward, the upper width of the auxiliary ladder platform 8 is greater than the lower width of the limiting ladder platform 7. The tilting block 13 will drive the auxiliary ladder platform 8 to move upward, and the auxiliary ladder platform 8 will move into the storage cavity 10 of the support frame 9. At this time, the tilting surface of the auxiliary ladder platform 8 will push the tilting block 13 to expand to both sides. That is, the moving rod 11 at the side end of the tilting block 13 compresses the auxiliary spring 12, and the tilting block 13 moves upward, thereby disengaging from the limiting ladder platform 7. The disassembly process also does not require any power tools, realizing quick disassembly, which facilitates the inspection, maintenance and recycling of the equipment, and improves the service life and resource utilization of the equipment.

[0025] Example 2: In this example, the cushioning material 31 on the back of the support frame 9 directly cushions the impact force that may be received on the back, preventing the structure from being damaged by bidirectional forces, and further improving the protective function. Specifically, as follows... Figure 1 , Figure 2 , Figure 10 and Figure 13 As shown, the following is disclosed: the buffer assembly includes a buffer member 2, which includes a telescopic structure, and a buffer spring 3 is sleeved on the outside of the telescopic structure. The side end of the buffer member 2 is connected to an external fluid delivery system through an air supply member 4. A metal steel bar cross structure 14 is provided inside the support frame 9. A cover plate 15 is connected to the surface of the support frame 9. A protective seat 16 is connected to the side surface of the cover plate 15 through the buffer assembly. A buffer seat 17 is provided inside the protective seat 16. A storage slot is opened inside the buffer seat 17, and an air box 18 is provided inside the storage slot. Two adjacent air boxes 18 are connected by an air supply member 4. The conveying pipe 19 is connected to the external fluid conveying system. The buffer component 2 on the surface of the support column 1 is fitted with a buffer spring 3. When the protective plate 5 is impacted, the buffer spring 3 first absorbs the initial impact force through elastic deformation. The buffer component 2 is connected to the external fluid conveying system through the air conveying component 4. The impact pressure pushes the buffer component 2 to compress. The external fluid conveying system further dissipates energy through gas or liquid flow, avoiding structural damage caused by hard impact. Therefore, the external fluid conveying system can be used for auxiliary protection according to the mine conditions, enhancing the adaptability of protection. The protection level can be flexibly adjusted for different impact intensities. The metal steel bar cross structure 14 inside the support frame 9 improves the overall impact resistance and effectively enhances the structural stability of the fence component, preventing frame deformation or breakage due to impact. The multi-level buffer design greatly improves the impact resistance of the device and reduces resource consumption and energy waste caused by frequent replacement. The side end of the cover plate 15 on the surface of the support frame 9 is connected to the protective seat 16 through the buffer component. When an external impact acts on the protective seat 16, the air box 18 in the buffer seat 17 is linked to the external fluid conveying system through the conveying pipe 19, and inflates. The box 18 is made of polyester fiber canvas with a polyvinyl chloride coating. It can withstand the instantaneous expansion tension during mining impacts and avoid tearing. The air box 18 inflates quickly and expands. Combined with the elastic deformation of the buffer component, it improves the overall impact resistance. The buffer material 31 on the back of the support frame 9 directly buffers the impact force that may be received on the back, preventing the structure from being damaged by bidirectional forces and further improving the protective function. The external fluid delivery system adjusts the pressure synchronously with the delivery pipe 19 through the air delivery component 4, which extends the service life of the buffer component and ensures the long-term stable operation of the protective system.

[0026] Example 3: In this example, by using the fixing bolt 24 to pass through the snap-fit ​​holes 23 at different positions, the extension length of the movable rod 22 can be adjusted, thereby adjusting the support angle and improving the environmental adaptability of the structure. Specifically, as shown below... Figure 1 ,Figure 2 , Figure 11 and Figure 12 As shown, a support assembly is provided on the back of the support frame 9. The support assembly includes a cross frame 20 installed on the back of the support frame 9. A movable rod 22 is connected to the cross frame 20 via a first rotating seat 21. The movable rod 22 has a snap-fit ​​hole 23. A sleeve 25 is movably connected to the bottom end of the movable rod 22. The movable rod 22 and the sleeve 25 are fixedly connected by a fixing bolt 24 passing through the snap-fit ​​hole 23. A movable plate 27 is connected to the bottom end of the sleeve 25 via a second rotating seat 26. A guide wheel 28 is installed under the movable plate 27. A support platform 29 is provided on the side of the cross frame 20. The upper end of the support platform 29 has a U-shaped guide groove for guiding the movement of the guide wheel 28. The guide wheel 28 has a locking member 30 for limiting movement. The support platform 29 has a locking groove that matches the locking member 30. A cushioning material 31 is installed on the back of the support frame 9. A counterweight box 32 is installed inside the support platform 29. The cushioning material 31 is a high-density polyurethane foam material with high energy absorption efficiency. It can absorb the impact force of the collision from the back of the mine through its own compression deformation, preventing the support frame 9 from deforming due to bidirectional force. The counterweight box 32 is installed inside the support platform 29. The cross brace 20 on the back of the support frame 9 is connected to the movable rod 22 via the first rotating seat 21. The movable rod 22 slides with the sleeve 25. The extension length of the movable rod 22 can be adjusted by the fixing bolt 24 passing through the snap-fit ​​holes 23 at different positions, thereby adjusting the support angle and improving the environmental adaptability of the structure. The sleeve 25 is connected to the movable plate 27 via the second rotating seat 26. The guide wheel 28 at the bottom of the movable plate 27 can be finely adjusted on the support platform 29 to ensure that the cross brace 20 forms a stable diagonal brace for the support frame 9, ensuring the effective transmission of the support force. The snap-fit ​​part 30 inside the guide wheel 28 adjusts the support angle. After adjustment, the guide wheel 28 is locked into the slot inside the support platform 29, so that the guide wheel 28 is rigidly connected to the support platform 29 through the locking member 30. At this time, the guide wheel 28 will neither rotate nor slide along the support platform 29, thus ensuring the stability of the support structure, avoiding safety hazards caused by accidental displacement, and reducing the energy consumption of repeated installation due to tipping. Since the locking member 30 is an existing screw locking structure, it will not be described in detail. The support platform 29 is supported on the ground and fixed to the ground. The counterweight box 32 inside the support platform 29 increases the weight at the bottom and improves the overall anti-tipping ability.
