Description

Technical Field

[0001] This utility model specifically relates to the technical field of anti-impact protection mechanisms for gangue silos, and more specifically to an anti-impact protection mechanism for gangue silos with a buffer structure. Background Technology

[0002] In the mining production process, gangue bins are core facilities for the temporary storage of gangue, undertaking the crucial tasks of gangue transfer and storage. However, for a long time, when gangue falls from a height, it carries enormous kinetic energy, causing a strong impact on the bin structure. Traditional gangue bins mostly use simple steel or concrete structures, lacking effective cushioning designs. Under continuous impact, the bin structure is prone to deformation and cracking, which not only significantly shortens its service life and increases equipment maintenance and replacement costs, but may also lead to safety hazards such as gangue leakage due to structural damage, affecting production continuity and the safety of the working environment.

[0003] Meanwhile, the complex composition of gangue, with some sharp and hard pieces exacerbating wear on the inner wall of the storage bin and reducing its sealing performance, and the traditional gate control of gangue storage bins is mostly manual or simple mechanical structure, which is prone to jamming during the opening and closing process, making it impossible to accurately control the flow of gangue, further leading to unstable impact of falling gangue and aggravating damage to the storage bin.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6In this embodiment of the utility model, an anti-impact protection mechanism for a gangue silo with a buffer structure includes a gangue silo body 1, on which controllable gates 2 are symmetrically installed on the front and rear sides; the lower end of the gangue silo body 1 is fixedly connected to the anti-impact protection mechanism 3.

[0031] The impact protection mechanism 3 includes a base support platform 31, which is a rectangular frame, and each of the four sides of the inner frame of the base support platform 31 is provided with a plurality of fixed seats 32, which are symmetrically arranged and have the same number of fixed seats 32.

[0032] The foundation bearing platform 31 has three fixed seats 32 installed symmetrically on the upper surface of the left and right sides, and each fixed seat 32 has a helical spring damper 33 fixedly installed on its upper end.

[0033] The upper ends of the helical spring dampers 33 are all fixedly connected to the support connecting seats 13. The support connecting seats 13 are arranged along the four sides of the upper outer frame of the chamber frame 11, and the number of support connecting seats 13 arranged symmetrically is the same.

[0034] The upper left and right sides of the silo frame 11 are symmetrically equipped with three support connecting seats 13; the silo frame 11 is tapered, and the upper front and rear sides of the silo frame 11 are symmetrically equipped with two support connecting seats 13.

[0035] The lower ends of the support connecting seats 13, which are symmetrically arranged on the front and rear sides of the upper end of the silo frame 11, are fixedly connected to the main support rod 14. The lower ends of the main support rod 14 are connected to the fixed seats 32, which are symmetrically installed on the upper surfaces of the front and rear sides of the foundation bearing platform 31. There are two fixed seats 32 on each of the symmetrically installed upper surfaces of the front and rear sides of the foundation bearing platform 31.

[0036] By adopting the above technical solution, the basic bearing platform 31 has a rectangular frame with symmetrically arranged fixed seats 32 and helical spring dampers 33, which, together with the main support rod 14 and support connecting seat 13, make the load of the silo frame 11 evenly distributed to the foundation structure, avoid local stress concentration, ensure the structural stability of the silo frame 11 under long-term impact and heavy load conditions, and reduce the risk of maintenance and production stoppage due to structural deformation.

[0037] In this embodiment, the inner four sides of the silo frame 11 are provided with elastic wear-resistant layers 12, the upper front and rear sides of the silo frame 11 are symmetrically equipped with hydraulic connecting rod connecting seats 16, and the lower left and right sides are symmetrically equipped with gate connecting seats 15.

[0038] By adopting the above technical solution, the helical spring damper 33 and the elastic wear-resistant layer 12 work together to construct a multi-level buffer system; the elastic wear-resistant layer 12 initially buffers the impact of falling gangue, and the helical spring damper 33 further absorbs and dissipates vibration energy, significantly delaying fatigue damage on the inner side of the silo frame 11, and significantly improving the impact resistance and service life of the silo frame 11.

[0039] In this embodiment, hydraulic drive cylinders 21 are installed on the hydraulic connecting rod connecting seat 16. The lower end of the hydraulic drive cylinder 21 is connected to the drive connecting rod 22. The lower end of the drive connecting rod 22 is connected to the connecting ear plate 23. The connecting ear plate 23 is fixedly installed on the arc gate 24. The arc gate 24 is correspondingly installed on the lower end of the silo frame 11.

[0040] By adopting the above technical solution, the controllable gate 2, composed of the symmetrically installed hydraulic drive cylinder 21 and the arc gate 24, realizes the automation and precise control of the unloading process; it can flexibly adjust the flow of gangue according to production needs, prevent excessive unloading impact, and the arc gate 24 opens and closes smoothly and is not easy to jam, improving the efficiency and safety of unloading operations and adapting to different production rhythms.

[0041] The working principle of this utility model is as follows: Gangue enters the silo frame 11 through the feed inlet. During the fall, the elastic wear-resistant layer 12 first contacts the gangue and absorbs part of the impact kinetic energy by its own elastic deformation, thereby reducing the direct impact on the silo frame. At the same time, the anti-impact protection mechanism 3 provides a stable support foundation based on the foundation bearing platform 31. The helical spring damper 33 on the fixed seat 32 works in conjunction with the support connecting seat 13 and the main support rod 14. When the silo is impacted and vibrates, the helical spring damper 33 converts the impact energy into heat energy and dissipates it through spring compression, extension and damping, thereby weakening the vibration transmission and ensuring the stability of the silo structure.

[0042] When unloading is required, the hydraulic drive cylinder 21 receives a control signal and generates thrust or pull, which is transmitted to the connecting lug 23 via the drive linkage 22, causing the arc gate 24 to rotate around the connecting structure, thus opening and closing the gate. By precisely controlling the extension and retraction of the hydraulic drive cylinder 21, the opening of the arc gate 24 can be adjusted, thereby controlling the flow rate and speed of the falling gangue, avoiding secondary impact caused by excessively fast unloading. In conjunction with the anti-impact protection mechanism 3, impact protection is optimized from the source of unloading. The helical spring damper 33 and the elastic wear-resistant layer 12 work together to construct a multi-level buffer system. The elastic wear-resistant layer 12 initially buffers the impact of falling gangue, and the helical spring damper 33 further absorbs and dissipates vibration energy, significantly delaying fatigue damage on the inner side of the silo frame 11, and significantly improving the impact resistance and service life of the silo frame 11.

[0043] The basic load-bearing platform 31 is symmetrically arranged with rectangular frame fixed seat 32 and helical spring damper 33, and together with main support rod 14 and support connection seat 13, so that the load of the silo frame 11 is evenly distributed to the foundation structure, avoiding local stress concentration, ensuring the structural stability of the silo frame 11 under long-term impact and heavy load conditions, and reducing the risk of maintenance and production stoppage due to structural deformation.

[0044] The controllable gate 2, consisting of a symmetrically installed hydraulic drive cylinder 21 and an arc-shaped gate 24, enables automated and precise control of the unloading process. It can flexibly adjust the flow rate of gangue according to production needs, prevent excessive unloading impact, and the arc-shaped gate 24 opens and closes smoothly and is not prone to jamming, thereby improving the efficiency and safety of unloading operations and adapting to different production rhythms.
