Description

Technical Field

[0001] This utility model relates to the technical field of locomotive parts storage equipment, and in particular to a locomotive brake disc storage device. Background Technology

[0002] Level 4 and 5 maintenance of railway locomotive wheelsets is crucial for ensuring the safe operation of locomotives. As the core component of wheelset braking, the locomotive brake disc is prone to accumulating rust, mud, and other foreign matter on its surface after long-term service, which can affect braking performance. Therefore, thorough cleaning is necessary during maintenance. With the development of railways towards high speed and heavy load, the efficiency and quality requirements for locomotive brake disc cleaning processes have also significantly increased.

[0003] In the pretreatment stage before laser rust removal of locomotive brake discs, the industry generally adopts a model of temporary storage, batch transfer, and decentralized processing. When large foreign objects that cannot be removed by laser are detected on the surface of the locomotive brake disc, workers use a bridge crane or hydraulic forklift to lift them to a temporary storage rack. After a certain number have accumulated, they are transferred in batches to the cleaning area. At this time, the locomotive brake discs are stored in close contact. To facilitate the cleaning of larger foreign objects on the locomotive brake discs, workers manually lift the locomotive brake discs one by one off the temporary storage rack and clean them. After cleaning, the locomotive brake discs are lifted to a pallet storage rack and returned to the laser rust removal loading area.

[0004] However, the close-packed stacking design of the storage racks conflicts with the pre-processing requirements. The locomotive brake discs obstruct each other, making direct processing impossible. Each disc must be lifted off the storage rack individually before operations can begin, adding an extra lifting step. Secondly, a single batch of locomotive brake discs requires multiple stages of individual transfer, which not only significantly increases the labor intensity of the workers but also noticeably increases the overall processing time, resulting in low operational efficiency. Furthermore, during frequent lifting operations, issues such as shaking of the lifting equipment and insecure fixing can easily lead to collisions, deformation, surface scratches, or even the discs falling off, posing significant safety hazards and quality risks.

[0005] Therefore, there is an urgent need to provide a locomotive brake disc storage device to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a locomotive brake disc storage device that can solve the problems of mutual obstruction of locomotive brake discs in traditional storage, and the cumbersome and risky transportation when cleaning is required.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] A locomotive brake disc storage device, comprising:

[0009] Base;

[0010] The support frame is vertically fixed to the base;

[0011] Multiple sets of support components are evenly spaced along the height direction of the support frame, and the distance between two adjacent sets of support components is greater than the thickness of the locomotive brake disc. Each set of support components includes at least three support members and at least three limiting blocks. The support members and limiting blocks of each set of support components correspond one-to-one and are respectively spaced around the support frame. The support members are rotatably connected to the support frame and have a storage position and a ready position.

[0012] In the initial state, the support members of the lowest support assembly are all in the preparatory position. Under the action of gravity, the support members abut against the base and partially protrude from the support frame. The support members of the other support assemblies are all in the storage position under the action of gravity. The locomotive brake disc can be sleeved on the support frame in the vertical direction and push the lowest support member to rotate until the support member abuts horizontally against the corresponding limiting block and supports the locomotive brake disc. When the support member rotates, it can push the adjacent upper support member to rotate from the storage position to the preparatory position to wait for the placement of the next locomotive brake disc.

[0013] Preferably, the support member includes a support portion and a pushing portion arranged at an angle. The support portion is rotatably connected to the support frame via a rotating shaft. When the support portion is pushed outward by the locomotive brake disc, the pushing portion rotates inward and can push against the pushing portion of the adjacent upper support member.

[0014] Preferably, the support portion is provided with a guide slope, and when the support member is in the storage position, the guide slope gradually tilts towards the support frame from top to bottom.

[0015] Preferably, the support frame includes at least three columns, which are circumferentially spaced around the base and the support member is rotatably connected to the columns.

[0016] Preferably, the tops of the columns are interconnected by horizontally arranged top grids, which are formed by multiple crossbars connected in a cross pattern.

[0017] Preferably, the base includes two first support beams and two second support beams. The two first support beams are arranged in parallel and spaced apart, and connected by the two second support beams arranged in parallel and spaced apart. The second support beams are perpendicular to the first support beams. The support frame includes four columns, which are fixed one-to-one to the upper surfaces of the two first support beams and the two second support beams. The columns are located at the midpoint of the fixed first support beam or the second support beam along the length direction.

[0018] Preferably, both the first support beam and the second support beam are square steel tubes.

[0019] Preferably, the surfaces of the support and / or the limiting block are coated with an anti-rust coating.

[0020] The beneficial effects of this utility model are:

[0021] This invention provides a locomotive brake disc storage device. Because multiple sets of support components are spaced apart along the height of the support frame with a spacing greater than the thickness of the locomotive brake disc, each locomotive brake disc is independently supported by a corresponding support component, and there is no close contact or obstruction between the discs. When a large foreign object that cannot be removed by laser is detected on the surface, it is not necessary to lift each disc from the storage rack individually as in the previous method; the target locomotive brake disc can be directly cleaned, thus reducing the safety and quality risks associated with frequent lifting. The locomotive brake disc is vertically mounted to push the support component to rotate, triggering the upper support component to rotate to the ready position. This allows for orderly storage of each disc on the same storage device, reducing multi-stage batch transfers and the need for workers to perform piece-by-piece transfers using bridge cranes or hydraulic forklifts. This reduces labor intensity, shortens overall processing time, and further reduces the safety and quality risks associated with frequent lifting. Attached Figure Description

[0035] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] like Figures 1-5As shown, this utility model provides a locomotive brake disc storage device, including a base 1, a support frame 2, and multiple sets of support components 3. The support frame 2 is vertically fixed on the base 1. The multiple sets of support components 3 are evenly spaced along the height direction of the support frame 2, and the distance between two adjacent sets of support components 3 is greater than the thickness of the locomotive brake disc 100. Each set of support components 3 includes at least three support members 31 and at least three limiting blocks 32. The support members 31 and limiting blocks 32 of each set of support components 3 correspond one-to-one and are respectively arranged circumferentially around the support frame 2. The support members 31 are rotatably connected to the support frame 2 and have a storage position and a ready position. In the initial state... The support members 31 of the lowest support assembly 3 are all in the ready position. Under the action of gravity, the support members 31 abut against the base 1 and partially protrude from the support frame 2. The support members 31 of the other support assemblies 3 are all in the storage position under the action of gravity. The locomotive brake disc 100 can be sleeved on the support frame 2 in the vertical direction and push the lowest support member 31 to rotate until the support member 31 abuts against the corresponding limit block 32 horizontally and supports the locomotive brake disc 100. When the support member 31 rotates, it can push the adjacent upper support member 31 to rotate from the storage position to the ready position to wait for the placement of the next locomotive brake disc 100.

[0037] The working principle of the locomotive brake disc storage device is as follows: In the initial state, such as Figure 1 As shown, the base 1 serves as the overall support foundation. The support frame 2, vertically fixed to the base 1, provides a central reference for the vertical mounting of the locomotive brake disc 100. Among the multiple sets of support components 3 evenly spaced along the height direction of the support frame 2, the support member 31 of the lowest set of support components 3 is in a preparatory position, that is, it rests against the base 1 under gravity and partially protrudes from the support frame 2, while the support members 31 of the other support components 3 are in a retracted position under gravity. When the first locomotive brake disc 100 needs to be placed, refer to... Figure 4 and Figure 5 The operator vertically mounts the locomotive brake disc 100 onto the support frame 2. As the disc descends, it pushes the support member 31 of the lowest support assembly 3 to rotate until the support member 31 horizontally abuts against the corresponding limiting block 32. At this point, the support member 31 stably supports the locomotive brake disc 100. Simultaneously, the rotation of the support member 31 pushes the support member 31 of the adjacent upper support assembly 3, causing it to rotate from its storage position to a ready position, awaiting the placement of the next locomotive brake disc 100. This process is repeated for each subsequent locomotive brake disc 100. By pushing the current support member 31 of the support assembly 3 to a horizontal supporting state, and simultaneously triggering the upper support member 31 to switch to the ready position, multiple locomotive brake discs 100 are placed independently and sequentially along the height of the support frame 2.

[0038] Firstly, because multiple sets of support components 3 are spaced apart along the height of the support frame 2 with a spacing greater than the thickness of the locomotive brake disc 100, each locomotive brake disc 100 is independently supported by the support member 31 of the corresponding support component 3, and there is no close contact or obstruction between the locomotive brake discs 100. When a large foreign object that cannot be removed by laser is detected on the surface, it is not necessary to lift it off the storage rack piece by piece as in the original mode. The target locomotive brake disc 100 can be directly cleaned, which also reduces the safety and quality risks caused by frequent lifting. The locomotive brake disc 100 pushes the support member 31 to rotate by vertically sleeved and triggers the upper support member 31 to rotate to the ready position. It can be stored in an orderly manner on the same storage device, reducing the number of batch transfers in multiple stages and reducing the number of operations for workers to transfer pieces by piece using bridge cranes or hydraulic forklifts. This reduces labor intensity, shortens the overall processing time, and further reduces the safety and quality risks caused by frequent lifting.

[0039] Specifically, such as Figure 1 and Figure 2 As shown, the support member 31 includes a support part 311 and a pushing part 312 arranged at an angle. The support part 311 is rotatably connected to the support frame 2 via a rotating shaft 33. When the support part 311 is pushed outward by the locomotive brake disc 100, the pushing part 312 rotates inward and can push against the pushing part 312 of the adjacent upper support member 31. When the locomotive brake disc 100 falls along the support frame 2 and pushes the support part 311, the support part 311 rotates outward around the rotating shaft 33. Since the support part 311 and the pushing part 312 are set at an angle, the pushing part 312 rotates inward synchronously, which can precisely push the pushing part 312 of the adjacent upper support 31, so that the upper support 31 can smoothly switch from the storage position to the ready position. No additional power is required. It is triggered entirely by the placement action of the locomotive brake disc 100 itself, avoiding the operation of manually adjusting the position of the support 31, reducing human intervention error, making the storage process of each locomotive brake disc 100 more continuous and stable, and reducing the complexity of operation for staff. In addition, the support part 311 and the pushing part 312 of the support 31 are integrated structures and are rotatably connected to the support frame 2 through the rotating shaft 33. The overall structure is simple and there are no complex transmission parts. During subsequent maintenance, only the flexibility of the rotating shaft 33 and the wear of the support part 311 and the pushing part 312 need to be checked, which reduces maintenance costs and difficulty.

[0040] In this embodiment, the rotating shaft 33 is a pin.

[0041] More specifically, the support part 311 is provided with a guide slope 3111. When the support part 31 is in the retracted position, the guide slope 3111 gradually tilts towards the support frame 2 from top to bottom. When the operator vertically places the locomotive brake disc 100 along the support frame 2, if the initial placement position of the locomotive brake disc 100 is slightly off, the inner edge of the locomotive brake disc 100 will first contact the guide slope 3111 of the support part 311 during the descent. Since the guide slope 3111 tilts towards the support frame 2 from top to bottom, it provides a centripetal guiding force for the off-center locomotive brake disc 100, achieving automatic centering and smooth descent, reducing the difficulty of operation, thereby avoiding collision between the inner edge of the locomotive brake disc 100 and the edge of the support part 311, and effectively reducing the risk of the support part 311 scratching the surface of the locomotive brake disc 100.

[0042] Specifically, such as Figure 1 and Figure 3 As shown, the support frame 2 includes at least three columns 21, which are circumferentially spaced around the base 1. The support member 31 is rotatably connected to the columns 21. Each column 21 is structurally independent, requiring no complex splicing, and can be directly fixed circumferentially along the axis of the base 1, simplifying the installation process. Furthermore, the multiple columns 21 are circumferentially spaced, forming a wide gap between adjacent columns 21. When the support member 31 rotates around the column 21, it will not interfere with other columns 21. Moreover, when the supporting part 311 and the pushing part 312 of the support member 31 rotate, they can complete their movements entirely within the gaps between the columns 21, without the need for additional clearance space. This ensures the flexibility of the support member 31's rotation and avoids rotation jamming caused by space constraints, further improving the operational reliability of the device.

[0043] More specifically, the tops of the columns 21 are interconnected by horizontally arranged top grids 22, which are formed by multiple crossbars 221 intersecting each other. By connecting the tops of multiple columns 21 into a whole through the crossbars 221, the lateral force and impact force can be dispersed, improving the device's anti-overturning ability; it can also restrain the vertical deformation of the columns 21, ensuring that the spacing of the support components 3 is uniform and ensuring the long-term stable use of the device.

[0044] More specifically, the base 1 includes two first support beams 11 and two second support beams 12. The two first support beams 11 are arranged in parallel and spaced apart, and connected by the two second support beams 12, which are also arranged in parallel and spaced apart. The second support beams 12 are perpendicular to the first support beams 11. The support frame 2 includes four columns 21, which are fixed one-to-one to the upper surfaces of the two first support beams 11 and the two second support beams 12. The columns 21 are located at the midpoint of the length of the fixed first support beam 11 or second support beam 12. The four columns 21 are fixed at the midpoint of the two first support beams 11 and the two second support beams 12. This ensures that the load from the upper support frame 2 and the locomotive brake disc 100 can be vertically transferred through the columns 21 to the structural midpoint of the first support beams 11 and the second support beams 12, i.e., the position with the smallest bending moment and the best bending resistance, making the stress on the entire base 1 more uniform and greatly improving its stability. Furthermore, the rectangular base 1 has a simple frame structure, consisting only of a first support beam 11 and a second support beam 12 connected together. This reduces the number of components and the connection points, lowering manufacturing and assembly complexity while still meeting the requirements for stability and load-bearing capacity. In this embodiment, each column 21 is evenly spaced with seven support members 31 along the vertical direction.

[0045] More specifically, both the first support beam 11 and the second support beam 12 are square steel tubes. Square steel tubes have the characteristics of hollow structure and rigidity. Under the same load-bearing capacity, the steel tubes are lighter, which not only reduces the overall weight of the base 1, making it easier to transport and install the device, but also reduces the load-bearing pressure on the ground and avoids damage to the ground caused by excessive weight of the base 1.

[0046] Specifically, the surfaces of the support member 31 and / or the limiting block 32 are coated with an anti-rust coating. This can isolate moisture and debris in the maintenance environment of the locomotive brake disc 100, prevent component corrosion, and extend the replacement cycle; it can also maintain the smoothness of the component surface, ensuring that the support member 31 can rotate flexibly around the rotating shaft 33 and accurately abut against the limiting block 32, preventing the locomotive brake disc 100 from shifting under support; at the same time, it eliminates the need for frequent rust removal steps, reduces maintenance manpower and component wear costs, and meets the needs of efficient maintenance.

[0047] In this embodiment, the anti-rust coating is a composite coating of epoxy zinc-rich primer and polyurethane topcoat.

[0048] In other embodiments, the anti-rust coating may also be a hot-dip galvanized coating. It should be noted that anti-rust coatings are a mature technology in the field, and the specific material can be selected and replaced according to the actual usage environment and cost requirements of the storage device.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
