Description

Technical Field

[0001] This invention belongs to the technical field of coal transportation equipment, and specifically relates to a foldable anti-slip baffle for coal transportation carriages. Background Technology

[0002] Coal transportation, as a crucial link in the energy logistics system, bears the important task of efficiently and safely transporting coal from mining sites to consumer terminals such as power plants, steel mills, and chemical enterprises. In my country, railways, with their advantages of large capacity, low cost, and suitability for long-distance transportation, have become the main mode of coal transportation. As the core equipment for railway coal transportation, the structural design of the transport carriages directly affects the overall transport capacity, loading and unloading efficiency, transportation safety, and environmental performance.

[0003] Currently, most coal transport cars use a rectangular box structure with an open top, fixed side walls, and a flat or slightly sloped bottom. To prevent coal from scattering during transport, tarpaulins are typically used to cover the top of the car, either manually or mechanically. This method is not only cumbersome but also hinders loading and unloading efficiency. To further reduce coal slippage, some cars have been fitted with fixed anti-slip baffles on the top, but this structure is difficult to adapt to diverse transport conditions and loading / unloading requirements.

[0004] For example, Chinese utility model patent CN222388983U discloses a hoisting and conveying device for inclined roadways in coal mines. It features a fixed baffle on one side of the top of the loading box, which, together with protective plates on both sides of the base and an inclined sliding plate, can prevent coal from falling onto the track to a certain extent. However, this baffle is a fixed structure that cannot be folded or rotated, lacking adaptability to complex transportation scenarios (such as loading and unloading coal), and suffers from problems such as limited functionality and application limitations.

[0005] To overcome the shortcomings of existing technologies, such as non-adjustable baffles and limited applicability, this invention proposes a foldable anti-slip baffle for coal transport vehicles to improve the functionality and adaptability of the baffle to different scenarios. Summary of the Invention

[0006] To address the aforementioned problems in the existing technology, this invention provides a foldable anti-slip baffle for coal transport vehicles, which is convenient to use, easy to adjust, and has a wide range of applications.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a foldable anti-slip baffle for a coal transport car, comprising a baffle body and a connecting assembly, wherein the baffle body is disposed on the top of the side wall of the coal transport car, and the connecting assembly is used to connect the baffle body to the coal transport car;

[0008] The connecting assembly includes a lower fixed beam and an upper fixed beam that can rotate relative to each other. The lower fixed beam is fixedly connected to the side wall of the coal transport car, and the upper fixed beam is rotatably connected to the baffle body.

[0009] A first locking mechanism is provided between the lower fixed beam and the upper fixed beam to fix the upper fixed beam, which is capable of rotating relative to the lower fixed beam.

[0010] The baffle body is provided in at least two parts, and is hinged sequentially along the vertical direction;

[0011] The upper fixed beam is rotatably connected to the baffle body located at the bottom layer.

[0012] The first locking mechanism includes a first positioning block;

[0013] The first positioning block is fixedly mounted on the top of the lower fixed beam to limit the rotational position of the upper fixed beam.

[0014] The upper fixed beam is provided with a positioning groove corresponding to the first positioning block. When the upper fixed beam rotates to be on the same vertical plane as the lower fixed beam, the first positioning block cooperates with the positioning groove to fix the upper fixed beam relative to the lower fixed beam.

[0015] The first locking mechanism further includes a first bolt, which passes through the first positioning block and is threadedly connected to the upper fixed beam.

[0016] It also includes a second locking mechanism for fixing the vertically positioned baffle body to the upper fixed beam;

[0017] The second locking mechanism includes a second positioning block and a second bolt. The two second positioning blocks are symmetrically fixed at both ends of the upper fixed beam, and the second bolt passes through the second positioning block and is threadedly connected to the baffle body.

[0018] It also includes a third locking mechanism, which is disposed between two adjacent baffle bodies and is used to lock the two baffle bodies in the unfolded state.

[0019] The third locking mechanism includes a third positioning block and a third bolt. The two third positioning blocks are symmetrically fixed at both ends of the lower baffle body, and the third bolt passes through the third positioning block and is threadedly connected to the upper baffle body.

[0020] It also includes a reinforcing unit, which is fixed to the side of the baffle body facing the interior of the coal transport car;

[0021] The reinforcing unit includes a first reinforcing member and a second reinforcing member;

[0022] Multiple first reinforcing members are equally spaced along the short side of the baffle body, and multiple second reinforcing members are equally spaced along the long side of the baffle body, forming a grid-like support structure.

[0023] Both the first and second reinforcing members are square tubular structures and are fixed to the side wall of the baffle body by welding.

[0024] The connecting assembly further includes a connecting shaft, which is rotatably connected to the middle of the lower fixed beam and the upper fixed beam, so that the lower fixed beam and the upper fixed beam are rotatably connected.

[0025] The beneficial effects of this invention are:

[0026] This invention provides a foldable anti-slip baffle for a coal transport car. Multiple foldable baffle bodies are connected vertically to the top of the side wall of the coal transport car to form a folding structure, which allows the baffle bodies to be folded for storage and unfolded for use. The total height can be changed by folding the baffle bodies located on the upper layer to meet different usage scenarios.

[0027] The main body of the baffle is rotatably connected to the side wall of the coal transport car via a connecting component, allowing the baffle body to be adjusted in angle to match coal loading and unloading application scenarios.

[0028] After the main body of the baffle is unfolded, it can be locked using the first locking mechanism, the second locking mechanism and the third locking mechanism, so that the main body of the baffle can be used flexibly while also having a stable and reliable fixing mechanism.

[0036] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0037] See appendix Figure 1-5 As shown, this embodiment of the invention provides a foldable anti-slip baffle for a coal transport car, including a baffle body 4 and a connecting assembly. The baffle body 4 is disposed on the top of the side wall of the coal transport car, and the connecting assembly is used to connect the baffle body 4 to the coal transport car. The connecting assembly includes a lower fixed beam 1 and an upper fixed beam 2 that can rotate relative to each other. The lower fixed beam 1 is fixedly connected to the side wall of the coal transport car, and the upper fixed beam 2 is rotatably connected to the baffle body 4. A first locking mechanism 5 is provided between the lower fixed beam 1 and the upper fixed beam 2 to fix the upper fixed beam 2 that can rotate relative to the lower fixed beam 1. By setting the lower fixed beam 1 and the upper fixed beam 2 that can rotate relative to each other, and cooperating with the first locking mechanism 5, the angle adjustment and reliable locking of the baffle body 4 relative to the side wall of the car are realized. This allows the baffle to flexibly adjust its tilt angle according to actual transportation and loading / unloading needs, effectively preventing coal from scattering from different directions when the train starts, brakes, and travels on curves, significantly improving the environmental adaptability and anti-slip effect of the baffle, and overcoming the shortcomings of the single function of existing fixed baffles.

[0038] At least two baffle bodies 4 are provided, and they are hinged sequentially along the vertical direction. The upper fixed beam 2 is rotatably connected to the baffle body 4 located at the bottom. In this embodiment, there are specifically two baffle bodies 4, including a first baffle located at the top and a second baffle located at the bottom, which are hinged together by a hinge.

[0039] By configuring the main body 4 of the baffle into multiple segments and hinged them vertically, the folding function of the main body 4 is achieved. During non-transportation periods or when returning empty, the main body 4 can be folded in segments, effectively reducing the overall height, avoiding interference with roadside facilities, and improving traffic passability and safety. At the same time, when maintenance is required, the segmented folding structure also facilitates operation on specific sections, simplifying the maintenance process.

[0040] The first locking mechanism 5 includes a first positioning block 51. The first positioning block 51 is fixedly disposed on the top of the lower fixed beam 1 and is used to limit the rotational position of the upper fixed beam 2. By setting the first positioning blocks 51 at both ends of the lower fixed beam 1, a clear and reliable mechanical limit is provided for the rotation of the upper and lower fixed beams, ensuring that the baffle can be accurately fixed when it is unfolded to the working position (usually in a vertical state), and preventing it from rotating accidentally during vehicle operation vibration.

[0041] The upper fixed beam 2 has a positioning groove 21 corresponding to the first positioning block 51. When the upper fixed beam 2 rotates to be on the same vertical plane as the lower fixed beam 1, the first positioning block 51 cooperates with the positioning groove 21 to fix the upper fixed beam 2 relative to the lower fixed beam 1. The first locking mechanism 5 also includes a first bolt 52, which passes through the first positioning block 51 and is threadedly connected to the upper fixed beam 2. The upper fixed beam 2 has a threaded hole corresponding to the first bolt 52.

[0042] By interlocking the positioning slot 21 with the first positioning block 51 and locking it with the first bolt 52, a quick and precise positioning and rigid connection between the upper and lower fixed beams is achieved. This not only makes operation simple but also ensures a strong connection, effectively resisting impacts and vibrations generated during vehicle operation and guaranteeing the stability of the connecting components during operation.

[0043] It also includes a second locking mechanism 6 for fixing the vertically positioned baffle body 4 to the upper fixed beam 2. The second locking mechanism 6 includes a second positioning block 61 and a second bolt 62. The two second positioning blocks 61 are symmetrically fixed at both ends of the upper fixed beam 2, and the second bolt 62 passes through the second positioning blocks 61 and is threadedly connected to the baffle body 4. The end of the baffle body 4 is provided with a first threaded hole 41 corresponding to the second bolt 62, and the second bolt 62 is threadedly connected to the baffle body 4 through the first threaded hole 41.

[0044] By setting the second positioning block 61 and the second bolt 62, the baffle body 4 in the vertical working state can be rigidly connected to the upper fixed beam 1. This effectively prevents the baffle body 4 from swinging or folding around its hinge point under the lateral pressure of coal, ensuring the structural strength and posture stability of the baffle when under load (in the transportation state of loaded coal), thereby ensuring continuous protection capability.

[0045] It also includes a third locking mechanism 7, which is located between two adjacent baffle bodies 4 and is used to lock the two baffle bodies 4 in the unfolded state. The third locking mechanism 7 includes a third positioning block 71 and a third bolt 72. The two third positioning blocks 71 are symmetrically fixed to both ends of the lower baffle body 4, and the third bolt 72 passes through the third positioning block 71 and is threadedly connected to the upper baffle body 4.

[0046] By setting the third positioning block 71 and the third bolt 72, the adjacent baffle bodies 4 can be locked in the fully unfolded state. This ensures that the multiple baffle sections can form a whole and share the force when unfolded.

[0047] Specifically, the first bolt 52, the second bolt 62, and the third bolt 72 are all regular hexagonal bolts.

[0048] Preferably, the bolt specifications are M8-M12 to ensure the connection strength of the locking mechanism, which can reliably resist the vibration during vehicle operation and the lateral impact force of coal, and prevent the bolt from loosening and causing locking failure; and the bolt surface is galvanized to improve rust resistance and adapt to the humid and dusty working conditions of coal transportation.

[0049] It also includes a reinforcing unit, which is fixed to the side of the baffle body 4 facing the interior of the coal transport car. The reinforcing unit includes a first reinforcing member 43 and a second reinforcing member 44. Multiple first reinforcing members 43 are equally spaced along the short side of the baffle body 4, and multiple second reinforcing members 44 are equally spaced along the long side of the baffle body 4. The first reinforcing members 43 and the second reinforcing members 44 form a grid-like support structure.

[0050] By installing a grid-like support structure composed of first and second reinforcing members on the inner side of the baffle, the overall rigidity and impact resistance of the baffle body 4 are significantly enhanced. This reinforcing unit can effectively disperse the local pressure caused by coal on the baffle, preventing the baffle from deforming or being damaged during long-term use or under large impact, thus extending the service life of the baffle. It is especially suitable for coal transportation conditions with large capacity and high load.

[0051] Both the first reinforcing member 43 and the second reinforcing member 44 are square tubular structures and are fixed to the side wall of the baffle body 4 by welding.

[0052] By employing a square tubular structure as a reinforcing member and fixing it by welding, excellent structural strength is ensured while also achieving lightweight design. The square tubular structure has good bending resistance, a large welding contact area with the plates, and high connection strength, allowing the entire reinforcing mesh to integrate seamlessly with the baffle body, working together to further enhance the stability and durability of the structure.

[0053] The connecting assembly also includes a connecting shaft 3, which is rotatably connected to the middle of the lower fixed beam 1 and the upper fixed beam 2, so that the lower fixed beam 1 and the upper fixed beam 2 can be rotatably connected.

[0054] By setting a connecting shaft 3 in the middle to achieve the rotational connection between the upper and lower fixed beams, the force transmission path of this structure is clear and the rotation is smooth. By setting a hinge point in the middle of the lower fixed beam 1 and the upper fixed beam 2, the force on the lower fixed beam 1 and the upper fixed beam 2 can be balanced when they rotate, reducing local stress concentration, making the rotation smoother, and reducing the difficulty of operation.

[0055] When loading and unloading coal, the angle of the baffle body 4 can be adjusted to avoid the mechanical operation range, thus avoiding obstruction of the loading and unloading process and improving operation efficiency. After the coal is loaded, it can be quickly rotated back to the vertical protection position and locked, which solves the problem of interference with loading and unloading caused by the fixed baffle in the existing technology.

[0056] Example 1:

[0057] Participate in the attached Figure 1 As shown, this embodiment provides a foldable anti-slip baffle for a coal transport car, including a baffle body 4, a connecting component, a locking mechanism, and a reinforcing unit.

[0058] The connecting assembly is the base for connecting the folding anti-slip baffle to the side wall of the car body, and includes a lower fixed beam 1 and an upper fixed beam 2. The lower fixed beam 1 is fixedly installed on the top of the side wall of the coal transport car body by welding or high-strength bolts. The lower fixed beam 1 and the upper fixed beam 2 are rotatably connected by a connecting shaft 3 passing through the middle of the two, which allows the upper fixed beam 2 to rotate relative to the lower fixed beam 1 within a certain angle range.

[0059] The connecting shaft 3 has a diameter of 16-20mm and is made of 45 steel. It is installed in the middle of the lower fixed beam 1 and the upper fixed beam 2. This setting ensures that the lower fixed beam 1 and the upper fixed beam 2 are subjected to balanced forces when rotating, reduces local stress concentration, makes the angle adjustment action smoother, reduces the difficulty of operation, and meets the shear strength requirements for long-term rotation.

[0060] In this embodiment, there are two baffle bodies 4: a lower baffle and an upper baffle. They are hinged vertically by hinges or other hinge components, thus enabling the baffle bodies 4 to fold. The upper fixed beam 2 is rotatably connected to the lower baffle 41 located at the bottom layer by a hinge.

[0061] Preferably, the baffle body 4 is made of Q235 steel plate with a thickness of 5-8mm, which ensures structural strength while making the baffle body 4 lightweight. The number of baffle bodies 4 can be set to 2-3 to adapt to the coal transportation needs at different heights, taking into account both protective effect and folding convenience.

[0062] The baffle in this embodiment has an unfolded working state and a folded storage state:

[0063] When it is needed for use, first unfold the upper baffle 42 from its folded state so that it is on the same vertical plane as the lower baffle 41. Then, tighten the third bolt 72 of the third locking mechanism 7 so that the third positioning block 71 firmly locks the upper and lower baffles together to form a whole, tall anti-slip plate.

[0064] Then, the operator pushes the integrated baffle body 4, causing it to rotate around the connecting shaft 3 until the upper fixed beam 2 and the lower fixed beam 1 are on the same vertical plane. At this point, the first positioning block 51, fixed to the top of the lower fixed beam 1, is precisely inserted into the corresponding positioning groove 21 at the bottom of the upper fixed beam 2, achieving initial positioning and limiting. Then, the first bolt 52 passes through the first positioning block 51 and is threadedly connected to the upper fixed beam 2 and tightened, thereby locking the upper and lower fixed beams.

[0065] Finally, to ensure that the baffle body 4 does not swing backward when subjected to coal compression, the second bolt 62 is passed through the second positioning block 61 fixed at both ends of the upper fixed beam 2, and threadedly connected to the side wall of the lower baffle 41 and tightened, so that the baffle body 4 is completely locked in the vertical working position, which can effectively prevent coal from scattering during transportation.

[0066] A multi-node locking system is formed by the first locking mechanism 5, the second locking mechanism 6 and the third locking mechanism 7. The system achieves comprehensive locking from three dimensions: the connection between the upper fixed beam 2 and the lower fixed beam 1, the fixing of the baffle body 4 to the upper fixed beam 2, and the connection between adjacent baffle bodies 4. This ensures that the baffle body 4 has no loosening space when it is in the deployed working state. Even if the vehicle brakes suddenly or the road is bumpy, it can prevent the baffle body 4 from rotating, folding or shifting accidentally, eliminate the risk of coal spillage, and improve the safety and reliability of transportation.

[0067] When the car needs to unload coal or return empty, operate in reverse order: first loosen the second bolt 62 to release the second locking mechanism 6; at this time, the entire baffle body 4 can be pushed to rotate backward and flatten with the upper fixed beam 2 as the axis. Alternatively, loosen the first bolt 52 to release the first locking mechanism 5, allowing it to rotate around the connecting shaft 3 to avoid loading and unloading machinery. If it is necessary to further reduce the height, the third bolt 72 can be loosened to fold the upper baffle 42 downward and overlap it with the lower baffle 41, greatly reducing the space occupied.

[0068] To further enhance the durability of the baffle body 4, in this embodiment, a reinforcing unit is fixedly installed on the side of the baffle body 4 (including the lower baffle and the upper baffle) facing the interior of the carriage. This reinforcing unit consists of multiple first reinforcing members 43 evenly spaced along the short side (vertical) of the baffle and second reinforcing members 44 evenly spaced along the long side (lateral). The first reinforcing members 43 and the second reinforcing members 44 are fixed by welding, forming a robust grid-like support structure. Both the first reinforcing members 43 and the second reinforcing members 44 are preferably square steel pipes. While ensuring excellent structural strength, the grid-like support structure is lightweight compared to the plate-like support structure, effectively resisting the impact and static pressure of coal and preventing baffle deformation.

[0069] Specifically, both the first reinforcing member 43 and the second reinforcing member 44 adopt a square tubular structure with a side length of 30-50mm and a wall thickness of 3-5mm. The spacing of the first reinforcing member 43 is set to 300-400mm, and the spacing of the second reinforcing member 44 is set to 200-300mm. This grid structure can effectively disperse the local pressure of coal on the baffle body 4. Compared with a baffle without reinforcing members, it can reduce deformation and significantly improve the impact resistance and service life of the baffle. The welds at the joints of the first reinforcing member 43, the second reinforcing member 44 and the baffle body 4 are full, ensuring connection strength and making the reinforcing unit and the baffle body 4 form an integral load-bearing structure, avoiding local detachment.

[0070] The foldable anti-slip baffle for coal transport carriages provided in this embodiment

[0071] The main body of the baffle 4 can be flexibly unfolded and folded, and its angle can be adjusted to adapt to various working conditions such as transportation, loading and unloading, and empty return trips. The multi-section baffle combined with a reliable locking mechanism can prevent coal from scattering in all directions while ensuring flexible unfolding and folding, thus meeting different transportation needs.

[0072] The multi-point locking mechanism and grid-like reinforcing ribs ensure the rigidity and lifespan of the baffle under harsh working conditions.

[0073] The folding structure reduces maintenance difficulty, and all locking mechanisms are bolted together for easy assembly and disassembly.

[0074] Example 2:

[0075] The foldable anti-slip baffle for coal transport carriages provided by the present invention includes a lower fixed beam 1, an upper fixed beam 2, a baffle body 4, a first locking mechanism 5, a second locking mechanism 6, and a third locking mechanism 7.

[0076] Furthermore, by Figure 1 and Figure 2As shown in this embodiment, the upper fixed beam 2 is rotatably mounted on the top of the lower fixed beam 1 via a connecting shaft 3. The two baffle bodies 4 are hinged together vertically and hinged to the top of the upper fixed beam 2. When the upper fixed beam 2 rotates to overlap with the lower fixed beam 1, it is locked by the first locking mechanism 5. When the lower baffle body 4 is flipped to a vertical position, it is locked to the upper fixed beam 2 by the second locking mechanism 6. When the two baffle bodies 4 are flipped to overlap, they are locked by the third locking mechanism 7. With the above scheme, in use, the lower fixed beam 1 is fixed to the top side of the coal transport car body by bolts or welding. The two baffle bodies 4 block the coal and prevent it from slipping. The two baffle bodies 4 are hinged together vertically and hinged to the top of the upper fixed beam 2 to form a folding structure, which facilitates the folding and unfolding of the two baffle bodies 4. The total height can be changed by folding the upper baffle body 4 to meet different usage scenarios. After the two baffle bodies 4 are unfolded, they are locked by the first locking mechanism 5, the second locking mechanism 6 and the third locking mechanism 7, which has high stability.

[0077] When it is necessary to flip the upper fixed beam 2 to change the orientation of the two baffle bodies 4, the first locking mechanism 5 should be released first. When it is necessary to flip the two baffle bodies 4, the second locking mechanism 6 and the third locking mechanism 7 should be released first.

[0078] Optionally, by Figure 1 and Figure 2 As shown, in this embodiment, the first locking mechanism 5 includes a first positioning block 51 and a first bolt 52. The first positioning block 51 is fixed to the top end of the lower fixed beam 1. A positioning groove 21 for the first positioning block 51 to be inserted is machined on the upper fixed beam 2. The first bolt 52 passes through the first positioning block 51 and is connected to the upper fixed beam 2 by threaded engagement. With the above scheme, when it is necessary to rotate the upper fixed beam 2, the following operation can be performed:

[0079] First, using a suitable tool, such as a wrench, rotate the first bolt 52 counterclockwise. Since the first bolt 52 is connected to the upper fixed beam 2 by a threaded engagement, during the rotation, the first bolt 52 will gradually come out of the first positioning block 51 and the upper fixed beam 2. When the first bolt 52 is completely out, the locking relationship between the upper fixed beam 2 and the first positioning block 51 is released.

[0080] Next, with the connecting shaft 3 as the center, rotate the upper fixed beam 2 horizontally, so that the upper fixed beam 2 rotates relative to the lower fixed beam 1, and the first positioning block 51 will disengage from the positioning groove 21.

[0081] Align the positioning groove 21 of the upper fixed beam 2 with the first positioning block 51 on the lower fixed beam 1, then insert the first bolt 52 into the hole on the first positioning block 51 and rotate it clockwise so that it is tightly connected to the upper fixed beam 2 by means of thread engagement. When the first bolt 52 is tightened, the first positioning block 51 is stably embedded in the positioning groove 21, and the upper fixed beam 2 is firmly locked in the position that coincides with the lower fixed beam 1.

[0082] Preferably, by Figure 1 and Figure 2 As shown in this embodiment, the outer wall of the first positioning block 51 abuts against the inner wall of the positioning groove 21. With the above solution, when in use, the outer wall of the first positioning block 51 abuts against the inner wall of the positioning groove 21, which can further improve the stability and accuracy of locking between the upper fixed beam 2 and the lower fixed beam 1.

[0083] It should be noted that the reason for setting the rotating upper fixed beam 2 is that the baffle body 4 cannot continue to rotate after rotating to the vertical position. In order to improve the stability of the baffle body 4 in supporting the coal, the baffle body 4 is preferably flipped up and down from the inside of the car.

[0084] Therefore, when it is necessary to store the main body of the baffle 4, the main body of the baffle 4 can only be flipped inside the car body. After the coal is loaded, it is easy to block the main body of the baffle 4 and affect its unfolding. Therefore, a rotating upper fixed beam 2 is set up. When it is necessary to store the main body of the baffle 4, the upper fixed beam 2 is rotated 180°. At this time, the upper fixed beam 2 coincides with the lower fixed beam 1, and the main body of the baffle 4 can be flipped outward for storage. Even after loading, it is easy to unfold the main body of the baffle 4 for use.

[0085] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, the first positioning block 51, the first bolt 52, and the positioning groove 21 are all centrally symmetrically distributed in twos. After adopting the above scheme, the stability and reliability of the connection between the upper fixed beam 2 and the lower fixed beam 1 are further enhanced during use.

[0086] Moreover, the centrally symmetrical design also has certain advantages in terms of maintenance and repair. If one of the first positioning blocks 51, the first bolt 52, or the positioning groove 21 has a problem, the other symmetrical structure can still maintain the connection between the upper fixed beam 2 and the lower fixed beam 1 to a certain extent, giving maintenance personnel more time to carry out repairs. At the same time, the symmetrical structure is also more convenient when replacing parts. Maintenance personnel can accurately install new parts based on the existing symmetrical parts, reducing the difficulty and cost of maintenance.

[0087] Optionally, by Figure 1 and Figure 3As shown, in this embodiment, the second locking mechanism 6 includes: a second positioning block 61 and a second bolt 62. The two second positioning blocks 61 are symmetrically fixed at both ends of the upper fixed beam 2. A first threaded hole 41 is machined on the baffle body 4. The second bolt 62 passes through the second positioning block 61 and is screwed into the first threaded hole 41 by thread engagement. With the above scheme, when it is necessary to unfold the baffle body 4 located in the lower layer to a vertical state and lock it, the following steps can be taken: First, confirm that the upper fixed beam 2 has been stably locked to the top of the lower fixed beam 1 by the first locking mechanism 5; then, manually rotate the baffle body 4 located in the lower layer slowly around its hinge point with the upper fixed beam 2. During the rotation process, pay attention to the posture of the baffle body 4 to ensure that it smoothly transitions to a vertical state.

[0088] When the baffle body 4 is flipped to a vertical position, the first threaded hole 41 on the baffle body 4 will be aligned with the holes on the second positioning blocks 61 at both ends of the upper fixed beam 2. Since the two second positioning blocks 61 are symmetrically fixed to both ends of the upper fixed beam 2, this symmetrical structure makes the alignment process easier. As long as the baffle body 4 is in the correct vertical position, the two first threaded holes 41 can be naturally aligned with the holes on the corresponding second positioning blocks 61.

[0089] Subsequently, the second bolt 62 is taken and inserted into the holes on the two second positioning blocks 61 respectively. Using a suitable wrench, the second bolt 62 is rotated clockwise. Because the second bolt 62 needs to be screwed into the first threaded hole 41 through thread engagement, during the rotation, the second bolt 62 will gradually enter the first threaded hole 41, and as the rotation proceeds, the thread engagement between the two will become tighter and tighter. When both second bolts 62 are tightened, the baffle body 4 is firmly locked onto the upper fixed beam 2. This locking method allows the baffle body 4 to be effectively constrained in both horizontal and vertical directions, and can withstand the impact and pressure generated by coal during transportation, ensuring that the baffle body 4 always remains in a vertical protective position.

[0090] Optionally, by Figure 1 and Figure 4As shown, in this embodiment, the third locking mechanism 7 includes a third positioning block 71 and a third bolt 72. The two third positioning blocks 71 are symmetrically fixed to both ends of the lower baffle body 4. A second threaded hole 42 is machined on the upper baffle body 4. The third bolt 72 passes through the third positioning block 71 and is screwed into the second threaded hole 42 by thread engagement. When it is necessary to unfold the upper baffle body 4 to increase the protection height or to fold it for storage, the specific operation process is as follows: When it is necessary to increase the protection height and unfold the upper baffle body 4, first ensure that the lower baffle body 4 has been stably locked on the upper fixed beam 2 by the second locking mechanism 6; then, manually hold the upper baffle body 4 and slowly flip it upward around the hinge point with the lower baffle body 4. During the flipping process, pay attention to the angle and position of the upper baffle body 4 at all times to ensure that it unfolds upward smoothly.

[0091] When the transportation task is completed and the upper baffle body 4 needs to be folded and stored, first use a wrench to rotate the two third bolts 72 counterclockwise. During the rotation, the third bolts 72 will gradually come out of the second threaded hole 42. When the third bolts 72 are completely out, the locking relationship between the upper baffle body 4 and the lower baffle body 4 is released.

[0092] Preferably, by Figure 1 and Figure 4 As shown, this embodiment also includes: a first reinforcing member 43 and a second reinforcing member 44. Multiple first reinforcing members 43 are fixed at equal intervals along the short side direction to the outer wall of the baffle body 4, and multiple second reinforcing members 44 are fixed at equal intervals along the long side direction to the outer wall of the baffle body 4, forming a grid structure with the first reinforcing members 43. With the above scheme, when the baffle body 4 is unfolded to the vertical state, the lateral pressure generated by the coal on the inner wall of the baffle body 4 will be transmitted to the first reinforcing members 43 and the second reinforcing members 44 through the grid nodes. For example, when the coal accumulation height reaches 2 / 3 of the baffle position, the grid structure can transform the single-point concentrated stress into bidirectional dispersed stress, which can reduce the deformation of the baffle body 4 compared to a baffle without reinforcing members.

[0093] Preferably, by Figure 1 and Figure 4 As shown in this embodiment, both the first reinforcing member 43 and the second reinforcing member 44 are square tubes and are welded and fixed to the outer wall of the baffle body 4. With the above solution, when in use, the square tubes are used as the first reinforcing member 43 and the second reinforcing member 44 and are welded and fixed to the outer wall of the baffle body 4, which brings more significant performance improvement and usage advantages to the entire anti-slip baffle system.

[0094] When the baffle body 4 is deployed to protect the coal, the reinforcing members of the square tube structure play an excellent supporting role. The square tube has good bending and torsional resistance and can effectively resist the lateral pressure of the coal on the baffle body 4.

[0095] When coal accumulates in the carriage and compresses the baffle, the closed cross-sectional shape of the square tube allows it to evenly distribute stress when subjected to force. For example, during transportation, when the vehicle encounters bumps or sudden braking, the coal will generate a large impact force. The square tube reinforcement can distribute these impact forces to the entire baffle body 4, avoiding baffle deformation or damage caused by local stress concentration.

[0096] Among them, the first reinforcing member 43 and the second reinforcing member 44 are square tubes with a side length of 30-50mm and a wall thickness of 3-5mm. The spacing of the first reinforcing member 43 is set to 300-400mm, and the spacing of the second reinforcing member 44 is set to 200-300mm. The first reinforcing member 43 and the second reinforcing member 44 are set at intervals to ensure the reinforcing effect while avoiding the increase in weight and cost caused by excessive reinforcement. The adjacent baffle bodies 4 are hinged with stainless steel hinges with a load-bearing capacity of ≥500kg to ensure that the hinge can withstand the lateral tensile force and impact when coal is piled up, and to avoid hinge failure.

[0097] Components not described in detail in this article are existing technologies.

[0098] The working principle and usage process of the present invention: When in use, the lower fixed beam 1 of the baffle body 4 of the present invention is fixed to the top side of the coal transport car by bolts or welding. The two baffle bodies 4 block the coal and prevent the coal from slipping.

[0099] The two baffle bodies 4 are hinged together in the vertical direction and hinged to the top of the upper fixed beam 2 to form a folding structure, which makes it convenient for the two baffle bodies 4 to be folded and stored and unfolded for use. The total height can be changed by folding the upper baffle body 4 to meet different usage scenarios.

[0100] After the two baffle bodies 4 are unfolded, they are locked by the first locking mechanism 5, the second locking mechanism 6 and the third locking mechanism 7, which provides high stability.

[0101] When it is necessary to flip the upper fixed beam 2 to change the orientation of the two baffle bodies 4, first release the lock of the first locking mechanism 5; when it is necessary to flip the two baffle bodies 4, first release the lock of the second locking mechanism 6 and the third locking mechanism 7.

The total height can be changed by folding the upper baffle body 4 to meet different usage scenarios. After the two baffle bodies 4 are unfolded, they are locked by the first locking mechanism 5, the second locking mechanism 6 and the third locking mechanism 7, which has high stability.
