Description

Technical Field

[0001] This utility model relates to the field of mining technology, and in particular to a support pile structure. Background Technology

[0002] In coal mining and transportation operations, mine cars are the core equipment for transferring coal from the mining area to the storage or processing area, and their operation relies on dedicated mine car tracks laid on support frames. However, in existing coal mine transportation systems, mine car tracks and support frames generally lack effective shock absorption mechanisms. When mine cars travel on the tracks, they experience significant vibrations due to factors such as track joints, uneven ground, and changes in the load on the mine cars themselves. This vibration not only causes the coal loaded on the mine cars to fall off, resulting in resource waste and reduced transportation efficiency, but it also accelerates wear and tear on the mine cars and tracks, shortening the equipment's lifespan. Furthermore, high-frequency vibrations may cause the support frame structure to loosen, posing safety hazards and seriously affecting the stability and safety of coal mine transportation operations. To address the aforementioned issues, Chinese Patent CN220079591U discloses a coal mine transport track support and a coal mine transport track. This support achieves elastic support for the track by incorporating buffer blocks, fixing blocks, and elastic elements between the base plate and the support plate. It attempts to absorb vibration energy through the deformation of the elastic elements, reducing the vibration amplitude during mine car movement and thus lowering the probability of coal falling. While this solution improves upon the shortcomings of traditional non-damping structures to some extent, providing basic buffering capacity for the track, it still has significant technical shortcomings in practical applications. First, its elastic component structure is too simple, using a single or a few sets of buffer springs as the core elastic components. The overall elastic buffering capacity is limited, making it difficult to cope with the large impact forces generated by heavy-load, high-speed mining cars, resulting in poor buffering performance. Second, the structure lacks a damping structure, relying solely on the elastic deformation of the springs for shock absorption. This leads to continuous reciprocating vibrations after vibration, which not only fails to effectively suppress the vibration amplitude but may also further exacerbate the bumps between the mining car and the track due to excessively high vibration frequency, thus increasing the risk of coal mine collapses. Furthermore, the support height of the support is fixed, making it unable to flexibly adjust according to actual transportation needs, such as adapting to the height of different mining car models or compensating for track wear. Its poor adaptability makes it difficult to meet the diverse needs of coal mine transportation scenarios. Therefore, the existing technology has certain defects and shortcomings, requiring improved design. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a support pile structure to more accurately resolve the problems described above.

[0004] This utility model is achieved through the following technical solution: This utility model proposes a support pile structure, including a base, a buffer mechanism fixedly installed on the top of the base, a telescopic mechanism fixedly installed on the inner side of the buffer mechanism, and a bearing plate fixedly installed on the top of the telescopic mechanism. The buffer mechanism includes a side frame, which is fixedly installed on the top two sides of the base. Buffer modules are fixedly installed on the inner side of the side frame in a linear arrangement at equal intervals. A main frame is fixedly installed on the inner side of the buffer modules. The telescopic mechanism is fixedly installed on the inner side of the main frame.

[0005] Furthermore, mounting holes are provided at all four corners of the base, and mounting holes are also provided at the center of both sides of the bottom of the support plate and at the center of both the front and rear sides. The mounting holes are countersunk holes, and the outer surface edges of the base and the support plate are rounded.

[0006] Furthermore, the telescopic mechanism includes a support sleeve, which is fixedly installed in the middle of the inner side of the main frame. A support slide rod is slidably connected to the inner side of the support sleeve. The top of the support slide rod is fixedly connected to the bottom of the bearing plate. Two limiting screws are threaded to the upper ends of both sides of the support sleeve, and the ends of the limiting screws penetrate the support sleeve.

[0007] Furthermore, side supports are fixedly installed on both sides of the top of the main frame. The inner side of the side support is fixedly connected to the outer side of the support sleeve. The top view shape of the internal cavity of the support sleeve and the top view shape of the support slide are both set as regular hexagons. The limiting screw is set as a hand-tightening screw.

[0008] Furthermore, support and reinforcement frames are fixedly installed at both ends of the outer side of the side frame. The bottom of the support and reinforcement frame is fixedly connected to the top of the base, and the overall shape of the support and reinforcement frame is triangular.

[0009] Furthermore, a support guide rod is fixedly installed at each of the four corners at the bottom of the support plate, and a support conduit is sleeved on the outer surface of the support guide rod. The bottom of the support conduit is fixedly connected to the top of the side frame.

[0010] Furthermore, the buffer module includes a fixed plate and a damper. The fixed plate is linearly arranged at equal intervals and fixedly installed inside the side frame. A fixed seat is fixedly installed on the inner side of the fixed plate. The fixed seat is generally arranged in an isosceles triangle. Buffer springs are linearly arranged at equal intervals on the inclined surfaces at the top and bottom of the inner side of the fixed seat. A connecting frame is fixedly installed on the outer end of the buffer spring. The main frame is fixedly installed inside the connecting frame. The damper is fixedly installed on both sides of the bottom of the main frame. The bottom of the damper is fixedly connected to the top of the base.

[0011] The beneficial effects of this utility model are: 1. During the application of this technical solution, by setting up a buffer mechanism with multiple sets of buffer modules and dampers, multiple sets of buffer springs can be used to absorb vibration energy during use. Then, the dampers suppress the reciprocating vibration of the buffer springs, thereby achieving the effect of efficiently absorbing and attenuating vibration. This solves the problem that the support in the prior art relies on only a single set or a few springs for shock absorption, has limited buffering capacity, and lacks a damping structure, resulting in continuous vibration. It can effectively cope with the impact force generated by the heavy-load high-speed travel of mine cars, reduce the vibration amplitude of the track and mine cars, and reduce the probability of coal mine falls. At the same time, the cooperation of the support reinforcement frame on the outside of the side frame with the support guide rod and support guide tube further improves the stability of the structure during vibration, avoids the side frame tilting or the load-bearing plate shifting, and ensures the overall reliable operation of the support. 2. During the application of this technical solution, by setting up a telescopic mechanism and multiple sets of hand-tightened limiting screws, the height of the bearing plate can be adjusted by sliding the support slide along the support sleeve during use. The limiting screws are then fixed by embedding them into the threaded holes of the support slide. The threaded holes in the support slide also enhance the connection stability, thereby achieving the effect of flexibly adjusting the support height and fixing it firmly. This solves the problems of fixed support height, inability to adapt to different mine car models or track wear compensation requirements, and insufficient connection stability in the existing technology. The hand-tightened limiting screws can be operated without additional tools, making on-site adjustment convenient. The overall structure can adapt to diverse coal mine transportation scenarios, while ensuring the stability of the support after adjustment, meeting the use requirements of track support under different working conditions.

Example 1

[0015] A support pile structure includes a base 1, a buffer mechanism 2 fixedly installed on the top of the base 1, a telescopic mechanism 3 fixedly installed on the inner side of the buffer mechanism 2, and a bearing plate 4 fixedly installed on the top of the telescopic mechanism 3. The buffer mechanism 2 includes side frames 21, which are fixedly installed on the top two sides of the base 1. Buffer modules 22 are fixedly installed on the inner side of the side frames 21 in a linear arrangement at equal intervals. A main frame 23 is fixedly installed on the inner side of the buffer modules 22. A telescopic mechanism 3 is fixedly installed on the inner side of the main frame 23. During application, the buffer mechanism 2 and the telescopic mechanism 3 work together to allow the base 1 to be fixed to the foundation ground first, the bearing plate 4 to be connected to the coal mine transport track, and the height of the bearing plate 4 to be adjusted to fit the track requirements using the telescopic mechanism 3. The buffer mechanism 2 then mitigates track vibration. In use, the bearing plate 4 bears the weight and vibration transmitted by the track and transmits the force to the telescopic mechanism 3, which is fixed to the buffer module 22. The inner side of the main frame 23 of the impact mechanism 2 can stably support the bearing plate 4 and adapt to different height requirements; the side frame 21 of the buffer mechanism 2 provides an installation frame for the buffer module 22. The buffer modules 22 arranged at equal intervals on the inner side of the side frame 21 can absorb vibration energy. The main frame 23 connects the telescopic mechanism 3 to the buffer module 22 to ensure effective force transmission. This design allows the device to flexibly adapt to the track height through the telescopic mechanism 3 and enhance the vibration buffering capacity through multiple sets of buffer modules 22. It solves the problems of fixed support height and limited buffering capacity in the existing technology, reduces the vibration amplitude when the mine car is running, reduces the probability of coal falling, and at the same time ensures the stability of the track support, meeting the basic usage requirements of the support for coal transportation.

[0016] Combination Figures 1-4As shown, mounting holes 5 are provided at all four corners of the base 1, and mounting holes 5 are also provided at the center of both sides of the bottom and the center of both front and rear sides of the bearing plate 4. The mounting holes 5 are countersunk holes. The outer edges of the base 1 and the bearing plate 4 are rounded. The telescopic mechanism 3 includes a support sleeve 31, which is fixedly installed in the center of the inner side of the main frame 23. A support slide rod 32 is slidably connected to the inner side of the support sleeve 31. The top of the support slide rod 32 is fixedly connected to the bottom of the bearing plate 4. Two limit screws are threaded to the upper ends of both sides of the support sleeve 31. The end of the positioning screw 33 passes through the support sleeve 31. Side supports 24 are fixedly installed on both sides of the top of the main frame 23. The inner side of the side support 24 is fixedly connected to the outer side of the support sleeve. The top view shape of the internal cavity of the support sleeve 31 and the top view shape of the support slide rod 32 are both set as regular hexagons. The positioning screw 33 is a hand-tightening screw. Support reinforcement frames 25 are fixedly installed on both ends of the outer side of the side frame 21. The bottom of the support reinforcement frame 25 is fixedly connected to the top of the base 1. The overall shape of the support reinforcement frame 25 is triangular.

[0017] The technical solution described in the above-described embodiments of this application, during the application of this device, through the setting of mounting holes 5, support sleeves 31, support slide rods 32, and support reinforcement frames 25, allows the base 1 to be fixed to the foundation ground and the support plate 4 to the bottom of the coal mine transport track by first using the mounting holes 5 at the four corners of the base 1 and the mounting holes 5 at the bottom of the bearing plate 4, respectively. The mounting holes 5 are countersunk holes to avoid the bolt heads protruding and affecting the surrounding structure. The outer edges of the base 1 and the bearing plate 4 are rounded to prevent personnel from bumping into them. If it is necessary to adjust the support height, loosen the hand-tightened limit screw 33, push the bearing plate 4 to drive the support slide rod 32 to slide along the inner side of the support sleeve 31. Both the support slide bar 32 and the support slide bar 32 are hexagonal in shape when viewed from above, which can prevent the support slide bar 32 from rotating. After adjusting to the target height, tightening the limit screw 33 can fix it. The side supports 24 on both sides of the top of the main frame 23 can enhance the stability of the support sleeve 31. The triangular support reinforcement frame 25 at both ends of the outer side of the side frame 21 can improve the connection strength between the side frame 21 and the base 1. This design makes the installation and fixing of the device more convenient, the height adjustment is flexible and the fixation is firm. The support reinforcement frame 25 and the side supports 24 further ensure the structural stability. The countersunk hole and the rounded corner improve the safety of use. It solves the problems of inconvenient installation, difficult height adjustment and insufficient stability of the support in the prior art, and meets the actual needs of coal mine transportation track support. Example 2

[0018] Combination Figures 1-3 and Figure 5As shown, support guide rods 6 are fixedly installed at the four corners of the bottom of the support plate 4. Support guide tubes 7 are sleeved on the outer surface of the support guide rods 6. The bottom of the support guide tubes 7 is fixedly connected to the top of the side frame 21. The buffer module 22 includes a fixed plate 221 and a damper 222. The fixed plate 221 is fixedly installed inside the side frame 21 in a linear arrangement with equal spacing. A fixed seat 223 is fixedly installed on the inner side of the fixed plate 221. The fixed seat 223 is arranged in an isosceles triangle. Buffer springs 224 are fixedly installed in a linear arrangement with equal spacing on the inclined surfaces of the top and bottom of the inner side of the fixed seat 223. A connecting frame 225 is fixedly installed on the outer end of the buffer spring 224. The main frame 23 is fixedly installed inside the connecting frame 225. The damper 222 is fixedly installed on both sides of the bottom of the main frame 23. The bottom of the damper 222 is fixedly connected to the top of the base 1.

[0019] In the above-described embodiments of this application, during the application of this device, by setting up support guide rods 6, support guide tubes 7, and a buffer module 22 including fixing plates 221 and dampers 222, the support guide rods 6 at the four corners of the bottom of the bearing plate 4 can slide along the inner side of the support guide tube 7 during use. When the bearing plate 4 is subjected to force or vibration, it can prevent horizontal displacement and ensure the stability of the structure. When the buffer module 22 is working, the fixing plates 221 arranged at equal intervals inside the side frame 21 provide the mounting base for the fixing seat 223. The isosceles triangular fixing seat 223 makes the buffer springs 224 at the top and bottom slopes of the inner side evenly stressed. When the main frame 23 is subjected to vibration transmission, the main frame 23 is squeezed or pulled by the connecting frame 225. The buffer spring 224 absorbs vibration energy through deformation. At the same time, the dampers 222 on both sides of the bottom of the main frame 23 can quickly suppress the reciprocating vibration of the buffer spring 224 and further attenuate the vibration amplitude. This design allows the device to ensure structural stability when dealing with vibrations generated by the movement of mine cars during transportation. It can also enhance the shock absorption effect by means of the cooperation between the support guide rod 6 and the support guide tube 7. This solves the problems of easy deviation and limited shock absorption effect of the support when the support vibrates in the existing technology. It makes the coal mine transportation track more stable during the support process, reduces the coal mine falling due to vibration, and meets the needs of coal mine transportation operations for support shock absorption and stability.

[0020] The working principle and advantages of this utility model are as follows: During the application of this device, the device is first installed and fixed. Bolts are passed through the mounting holes 5 at the four corners of the base 1 to fix the base 1 to the foundation ground below the coal mine transport track. By setting the mounting holes 5 with countersunk holes, the bolt heads can be prevented from protruding and affecting the surrounding structure during use. The outer surface of the base 1 is rounded at the corners to prevent personnel from being bumped and injured. The base 1 provides a bearing foundation for the entire support pile structure. Then, the bearing plate 4 is fixedly connected to the bottom of the coal mine transport track through the mounting holes 5 at the middle of the bottom two sides and the middle of the front and rear sides. The outer surface of the bearing plate 4 is also rounded at the corners. The bearing plate 4 is used to bear the weight of the track and transmit the vibration of the track to the telescopic mechanism 3 and the buffer mechanism 2 below, laying the foundation for subsequent shock absorption and buffering work. After installation, if the support height needs to be adjusted according to the mine car model or track wear, first loosen the hand-tightened limiting screws 33 at the upper ends of both sides of the support sleeve 31, so that the ends of the limiting screws 33 are disengaged from the surface of the support slide rod 32. During use, threaded holes can be opened on the support slide rod, and corresponding threaded holes are also opened on the support slide rod 32 to accommodate the ends of the limiting screws 33. At this time, push the bearing plate 4 up and down, and the bearing plate 4 will drive the bottom support slide rod 32 to slide along the inner side of the support sleeve 31. The top view of the support slide rod 32 and the support sleeve 31 are both regular hexagonal. This shape design can prevent The support slide rod 32 rotates during the sliding process, thereby ensuring the levelness of the bearing plate 4. After adjusting to the target height, tighten the limiting screw 33 so that the end of the limiting screw 33 is embedded in the threaded hole of the support slide rod 32. The threaded hole on the support slide rod can be used with corresponding fasteners to further enhance the connection stability between the support slide rod and the surrounding structure. The setting of multiple limiting screws 33 can improve the support reinforcement effect and enhance the support stability after the overall fixation. The side supports 24 on both sides of the top of the main frame 23 can enhance the connection stability between the support sleeve 31 and the main frame 23 and prevent the support sleeve 31 from shaking when under force. After installation, during use, when the mine car vibrates while traveling on the track, the vibration is transmitted to the bearing plate 4 through the track. The bearing plate 4 drives the bottom support slide rod 32 and the support guide rod 6 to move together. The support guide rod 6 slides along the inner side of the support guide tube 7. This cooperation can prevent the bearing plate 4 from shifting horizontally during vibration, ensuring the overall stability of the structure. The support slide rod 32 transmits the vibration to the main frame 23. The main frame 23 drives the outer connecting frame 225 to move synchronously. The connecting frame 225 will compress or stretch the buffer spring 224 in the buffer module 22. The buffer spring 224 is fixed on the inclined surface at the top and bottom of the inner side of the fixed seat 223. The fixed seat 223 is an isosceles triangle, which makes the buffer spring 224 evenly stressed. When subjected to pressure, all of them... The buffering force of the buffer spring 224 can be concentrated at the center of the main frame 23, thereby further improving the buffering effect and stability. In conjunction with the damper 222, the buffering effect can be further enhanced. The fixing plates 221 are evenly spaced and fixed inside the side frame 21 to ensure that the buffer module 22 is stable inside the side frame 21. The buffer spring 224 absorbs part of the vibration energy through its own deformation. At the same time, the dampers 222 on both sides of the bottom of the main frame 23 start to work. The dampers 222 can quickly suppress the reciprocating vibration after the deformation of the buffer spring 224 and attenuate the vibration amplitude. The support and reinforcement frame 25 at both ends of the outer side of the side frame 21 is triangular. The triangular structure has high stability and can enhance the connection strength between the side frame 21 and the base 1, preventing the side frame 21 from tilting or deforming under vibration. As can be seen, this device, through the cooperation of multiple buffer modules 22 and buffer springs 224, solves the problem of limited buffering capacity of existing supports. The simultaneous deformation of multiple buffer springs 224 can absorb more vibration energy, which can cope with the impact force generated by the heavy-load high-speed travel of mine cars and reduce the probability of coal mine collapse. The setting of damper 222 solves the problem of lack of damping structure in existing supports, which can quickly suppress reciprocating vibration and reduce vibration frequency. The telescopic mechanism 3 cooperates with multiple sets of limit screws 33, and the threaded holes on the support slide can further strengthen the connection, solving the problems of non-adjustable height and insufficient connection stability of existing supports, adapting to different scenario requirements. The hand-tightened limit screws 33 can be operated without additional tools, which is convenient for on-site adjustment. The cooperation of support guide rod 6 and support guide tube 7, and the triangular design of support reinforcement frame 25, further improve the structural stability. The setting of countersunk hole and rounded corner enhances the safety of use. Overall, it realizes stable support and efficient vibration reduction of coal mine transportation track, meeting the use requirements of coal mine transportation operations for supports. The scope of protection of this application does not involve improvements to the electronic components of the device or equipment. Therefore, the working principles of each electronic component are not described in detail here. The electronic components in this application are all conventional electronic components used in the prior art. They are all conventional technical means in the prior art, and the application of the prior art is very mature. Therefore, they will not be elaborated here.

[0021] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
