Description

Technical Field

[0001] This application relates to the field of train parts technology, and in particular to the design of a wheel storage unit and a wheel storage stacking module. Background Technology

[0002] The storage of train wheels is a crucial part of vehicle maintenance. There is a significant demand for storing train wheels, especially in railway vehicle repair workshops and storage centers.

[0003] There are two traditional methods for placing train wheels: one is to lay the wheels flat on the ground one by one, but this method takes up too much space, has low site utilization, and is inconvenient for lifting the wheels. The second method is to use a pallet made of welded steel bars to form a simple wheel placement platform, and then stack the train wheels on the pallet. This method poses safety hazards and is also prone to causing wear and tear between the wheels.

[0004] Therefore, existing wheel storage methods suffer from low space utilization, inconvenient access, and easy wear and tear, making it difficult to meet the needs of efficient management and space optimization. Utility Model Content

[0005] This application provides a wheel storage unit and a wheel storage stacking module to solve at least one of the problems of low space utilization, inconvenient access, and easy wear in the prior art when storing wheels.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] A first aspect of this application provides a wheel storage unit, comprising: a base, the base including a support frame and a guide post; wherein the guide post is connected to the center of the support frame and extends along the height direction of the support frame; the support frame is configured to allow wheels to be stacked along the height direction of the support frame, and the guide post is configured to pass through a central hole of the wheel; and an isolation assembly including two opposing isolation members movably connected to opposite sides of the support frame; wherein the isolation members have a laid-out state and a retracted state; when the isolation members are in the laid-out state, the isolation members are placed between two adjacent wheels; when the isolation members are in the retracted state, the isolation members can provide clearance space for the storage and retrieval of wheels below the isolation members.

[0008] As an alternative implementation, the isolation element includes: a plate that can move relative to the support frame; and a buffer layer connected to opposite sides of the plate in the thickness direction.

[0009] As an optional implementation, it further includes: a sliding member, which is connected to the isolation member and sleeved on the support frame, and can slide along the height direction of the support frame; and a fixing member, which is detachably connected between the sliding member and the support frame.

[0010] As an optional implementation, the isolator is rotatably connected to the slider.

[0011] As an alternative implementation, the base also includes a base plate disposed on the inner bottom wall of the support frame, and the bottommost wheel is in contact with the base plate.

[0012] As an optional implementation, a buffer structure is provided on the side of the base plate facing the isolation member.

[0013] As an optional implementation, there are at least two isolation components; the multiple isolation components are spaced apart along the height direction of the support frame.

[0014] As an optional implementation, the support frame includes: an upper support frame, a lower support frame, and legs connecting the corners of the two; wherein, the lower support frame includes an outer rectangular frame and a diagonal beam; the diagonal beam is connected to the diagonal of the outer rectangular frame.

[0015] As an optional implementation, the support frame further includes a limiting member, which is connected between the upper support frame and the lower support frame and is located on the side of the two opposing isolation members that are far apart from each other.

[0016] As an optional implementation, the support frame further includes: a reinforcing member connected between the outer rectangular frame and the inclined beam, and / or between adjacent inclined beams.

[0017] A second aspect of this application provides a wheel storage stacking module, including at least two of the aforementioned wheel storage units, each wheel storage unit being stackable along the height direction of the wheel storage unit.

[0018] As an optional implementation, a positioning element is provided at the top of the support frame, and a positioning hole is provided at the bottom of the support frame; and / or, a positioning element is provided at the top of the guide column, and a positioning hole is provided at the bottom of the inclined beam of the support frame; and, the positioning element of one of the adjacent wheel storage units is connected to the positioning hole of the other.

[0019] The wheel storage unit and wheel storage stacking module provided in this application include a base and an isolation assembly. The base includes a support frame and guide posts. The guide posts are connected to the center of the support frame and extend along the height direction of the support frame. The support frame is configured to allow wheels to be stacked along the height direction of the support frame, and the guide posts are configured to pass through the center holes of the wheels. The isolation assembly includes two opposing isolation members, which are movably connected to opposite sides of the support frame.

[0020] Furthermore, the spacer has both an installed and a retracted state. When installed, the spacer is placed between two adjacent wheels. When retracted, the spacer provides clearance for the wheels located beneath it.

[0021] With this configuration, the wheels can be stacked one by one along the height of the support frame under the guidance of the guide column and stored on the support frame. This can effectively reduce the area required for wheel storage, improve space utilization, and facilitate the positioning of the wheels when hoisting equipment stores and retrieves them.

[0022] Furthermore, by introducing spacers, the wheels can be separated from each other, reducing the chance of wear between adjacent wheels due to direct contact, thereby alleviating the wear problem that may occur when wheels are stacked.

[0023] Furthermore, since the isolation component and the support frame are movably connected on opposite sides, the laying and storage states of the isolation component can be switched according to the specific operational needs on site, thereby further optimizing the efficiency of wheel storage and retrieval.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0039] The storage of train wheels is a crucial part of vehicle maintenance. There is a significant demand for storing train wheels, especially in railway vehicle repair workshops and storage centers.

[0040] There are two traditional wheel placement methods:

[0041] The first method involves laying the wheels flat on the ground one by one and then lifting them using a hoisting device. However, due to the large size and weight of train wheels, this method requires too much space, especially when storing multiple wheels, resulting in low site utilization and wasted space. Furthermore, due to insufficient space underneath, the hoisting equipment cannot grip the wheels when they need to be retrieved or stored, and even if successfully gripped, the hoisting equipment still needs to be moved multiple times, leading to low operational efficiency.

[0042] The second method involves placing the wheels on a simple wheel storage platform, which may include a pallet on which the train wheels can be stacked. However, this method presents safety hazards, and the contact between upper and lower wheels during storage can lead to wear, scratches, and other damage. Furthermore, it makes handling by hoisting equipment inconvenient, affecting operational efficiency.

[0043] In summary, traditional wheel storage methods often suffer from low space utilization, inconvenient access, and easy wear and tear, making it difficult to meet the needs of efficient management and space optimization.

[0044] In view of this, embodiments of this application provide a wheel storage unit and a wheel storage stacking module. The wheel storage unit includes a base and an isolation assembly. The base includes a support frame and a guide post. The guide post is connected to the center of the support frame and extends along the height direction of the support frame. The support frame is configured to allow wheels to be stacked along the height direction of the support frame, and the guide post is configured to pass through the center hole of the wheel. The isolation assembly includes two opposing isolation members, which are movably connected to opposite sides of the support frame.

[0045] Furthermore, the spacer has both an installed and a retracted state. When installed, the spacer is placed between two adjacent wheels. When retracted, the spacer provides clearance for the wheels located beneath it.

[0046] With this configuration, the wheels can be stacked one by one along the height of the support frame under the guidance of the guide column and stored on the support frame. This can effectively reduce the area required for wheel storage, improve space utilization, and facilitate the positioning of the wheels when hoisting equipment stores and retrieves them.

[0047] Furthermore, by introducing spacers, the wheels can be separated from each other, reducing the chance of wear between adjacent wheels due to direct contact, thereby alleviating the wear problem that may occur when wheels are stacked.

[0048] Furthermore, since the isolation component and the support frame are movably connected on opposite sides, the laying and storage states of the isolation component can be switched according to the specific operational needs on site, thereby further optimizing the efficiency of wheel storage and retrieval.

[0049] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0050] Figure 1 This is a schematic diagram illustrating the usage state of the wheel storage unit provided in an embodiment of this application.

[0051] Reference Figure 1As shown, this application embodiment provides a wheel storage unit 10. The wheel storage unit 10 includes a base 100 and an isolation component 200.

[0052] The base 100 includes a support frame 120 and a guide post 110. The guide post 110 is connected to the center of the support frame 120 and extends along the height direction of the support frame 120. The support frame 120 is configured to allow wheels 20 to be stacked along its height direction, and the guide post 110 is configured to pass through the center hole 21 of the wheel 20. This allows multiple wheels 20 to be stacked sequentially on the support frame 120, reducing the space required for wheel storage and improving space utilization. Furthermore, the guide post 110 guides the hoisted wheels 20, reducing the possibility of center of gravity shift during stacking and improving the stability of the stacked wheels 20.

[0053] For example, when it is necessary to place the wheel 20, the hoisting equipment can use the guide column 110 as a reference to move the center hole 21 of the wheel 20 to the position of the guide column 110, and then lower the wheel 20 one by one onto the support frame 120. At this time, under the constraint of the guide column 110, the radial offset distance of each wheel 20 is small when it is placed, which can improve the stability of the wheel storage unit 10, making it less likely to tip over and ensuring good safety.

[0054] The isolation assembly 200 includes two opposing isolation members 210. The isolation members 210 are movably connected to opposite sides of the support frame 120. For example, the isolation members 210 can be slidably connected to the support frame 120, or rotatably connected to the support frame 120, or both slidably and rotatably connected to the support frame 120; no limitation is made here.

[0055] Furthermore, the spacer 210 has both an installed state and a retracted state. When the spacer 210 is in the installed state, it is placed between two adjacent wheels 20. When the spacer 210 is in the retracted state, it provides clearance for the wheels 20 below it to access the wheel.

[0056] It should be noted that the isolation components 200 can be set as one group or multiple groups. For example, there can be two, three, or four groups of isolation components 200, which can be adjusted as needed. No specific limit is made here. When there are multiple groups of isolation components 200, the support frame 120 can be divided into multi-layer stacking spaces.

[0057] For example, when two sets of isolation components 200 are provided. Figure 1 As shown, refer to Figure 1In the paper orientation, the three wheels 20 are stacked from bottom to top. When it is necessary to place the bottom wheel 20, the multiple separators 210 located above the bottom wheel 20 and connected to the support frame 120 can be switched to the storage state. In this way, operating space is freed up for the placement of the bottom wheel 20, so that the bottom wheel 20 can be placed on the support frame 120.

[0058] Once the bottom wheel 20 is in place, the isolation piece 210 adjacent to the bottom wheel 20 (middle layer) can be switched to the laying state, and the hoisting equipment can then place another wheel 20 (middle layer wheel 20) on top of the bottom wheel 20. At this time, the isolation piece 210 of the middle layer can be sandwiched between the bottom wheel 20 and the middle layer wheel 20, so that there is a certain gap between the two wheels 20.

[0059] This reduces wear on the surface of adjacent wheels 20 caused by relative friction due to direct contact. Furthermore, because the two wheels 20 are separated from each other, it provides sufficient operating space for the lifting equipment's grippers to clamp the wheels 20 when they are subsequently retrieved, making the retrieval of the wheels 20 more convenient.

[0060] Similarly, after the intermediate layer wheels 20 are placed, the isolation piece 210 adjacent to the intermediate layer wheels 20 (upper layer) can be switched to the laying state, and the hoisting equipment can place another wheel 20 (upper layer wheel 20) on top of the intermediate layer wheels 20. At this time, the upper layer isolation piece 210 can be sandwiched between the intermediate layer wheels 20 and the upper layer wheels 20, so that there is a certain gap between the two wheels 20.

[0061] Understandably, during the entire storage process, the weight of the upper wheel 20 can be transferred to the lower wheel 20 through the spacer 210, and is ultimately supported by the bottom of the support frame 120. There is a certain distance between the two spacers 210 in the same spacer assembly 200. The spacer 210 can avoid the guide post 110 while also contacting the surface of the wheel 20, thus separating adjacent wheels 20.

[0062] In one implementation, there are at least two isolation components 200, which are spaced apart along the height direction of the support frame 120. In this way, the wheels 20 can be stacked along the height direction of the support frame 120, and the wheel storage unit 10 can store at least three wheels 20, which significantly reduces the space occupied by the wheel 20.

[0063] For example, two isolation components 200 can be provided. In this way, the support frame 120 can be divided into three layers of space and can be used to stack three wheels 20, thereby achieving efficient utilization of storage space.

[0064] Of course, there can be more than two isolation components 200, such as three, four, or five. Understandably, as the number of isolation components 200 increases, although the wheel storage unit 10 can accommodate more wheels 20, the weight that the support frame 120 needs to bear also increases, requiring higher reliability and stability from the support frame 120, which may lead to increased costs.

[0065] The following explanation uses two isolation components, 200, as an example.

[0066] Figure 2 This is a schematic diagram of the wheel storage unit provided in an embodiment of this application. (Refer to...) Figure 2 As shown, the isolation member 210 may include a plate 211 and a buffer layer 212.

[0067] The plate 211 is movable relative to the support frame 120. For example, the plate 211 can translate, rotate, or both translate and rotate relative to the support frame 120. A buffer layer 212 is connected to opposite sides of the plate 211 in the thickness direction. Thus, the movement of the plate 211 is more reliable due to its inherent rigidity.

[0068] By providing buffer layers 212 on the upper and lower sides of the plate 211, the wheels 20 above the plate 211 and the wheels 20 below the plate 211 can both come into contact with the buffer layers 212, thereby further reducing the possibility of wear between the wheels 20 and also reducing the impact on the lower wheels 20 when the upper wheels 20 are stacked.

[0069] For example, the buffer layer 212 can be made of a wear-resistant and non-slip material, such as nitrile rubber sheet, so that the surface of the train wheel 20 can be protected by the buffer layer 212 to prevent scratches, collisions or other damage. In addition, it can also prevent the train wheel 20 from sliding on the surface of the plate 211.

[0070] Based on this, multiple small holes can be distributed on the buffer layer 212. When the buffer layer 212 is compressed, the small holes allow the rubber wall to bend and collapse into the holes. This allows the buffer to deform under relatively small forces, optimizing the buffering effect. At the same time, the presence of small holes guides the deformation mode of the material, making the buffering process more linear and controllable.

[0071] It is understood that the buffer layer 212 can be semi-circular, and the buffer layer 212 can cover the contact area between the separator 210 and the wheel 20.

[0072] As another implementation, the spacer 210 can also be a flexible element. This allows the flexible element to provide cushioning and anti-wear protection for the wheel 20.

[0073] Continue to refer to Figure 2As shown, the wheel storage unit 10 may further include a sliding member 310 and a fixing member 320. The sliding member 310 is connected to the isolation member 210 and is sleeved on the support frame 120, and can slide along the height direction of the support frame 120. The fixing member 320 is detachably connected between the sliding member 310 and the support frame 120.

[0074] The slider 310 corresponds to the spacer 210. For example, one spacer 210 can correspond to two sliders 310, or one spacer 210 can correspond to three sliders 310 or four sliders 310. No limitation is made here.

[0075] It should be noted that the movable sleeve can be made of high-strength materials, such as metal or alloy materials, to ensure the stability of the isolation component 210 when it slides, rotates, or flips.

[0076] In some embodiments, the fastener 320 may pass through the slider 310 and abut against the support frame 120.

[0077] For example, an adjusting pin can be installed on the slider 310. When the slider 310 is adjusted up and down in the height direction of the support frame 120, the adjusting pin is released. After the position adjustment is completed, the adjusting pin is tightened so that the slider 310 is held against the support frame 120 and cannot move. If the position of the slider 310 needs to be adjusted again, the adjusting pin is released again.

[0078] In this way, the sliding member 310 can drive the isolation member 210 to be located at any height of the support frame 120, thereby improving the flexibility and applicable scenarios of the wheel storage unit 10, without affecting the overall rigidity of the support frame 120.

[0079] It is understandable that the weight of the wheel 20 is transferred to the support frame 120 layer by layer. The fastener 320 can be used to prevent the isolation member 210 from falling when it is in the stored state. Since the isolation member 210 itself is relatively light, the friction generated when the fastener 320 abuts against the support frame 120 can effectively support the isolation member 210.

[0080] In other embodiments, the support frame 120 may have multiple mating holes (not shown), through which the fixing member 320 passes sequentially through the sliding member 310 and the mating holes on the support frame 120, locking the sliding member 310 at a certain height. This further enhances the stability of the connection between the sliding member 310 and the support frame 120, preventing the sliding member 310 from slipping off the support frame 120.

[0081] In addition, the fixing member 320 can be set on the side of the sliding member 310 away from the isolation member 210, so as to avoid interference between the isolation member 210 and the fixing member 320 when the isolation member 210 moves relative to the support frame 120.

[0082] With the above settings, the position of the isolation member 210 in the height direction of the support frame 120 can be adjusted by the slider 310, and the slider 310 can be fixed at different heights by the fixing member 320. Thus, the user can adjust the distance between the isolation members 210 in different isolation components 200 according to the different thicknesses of the wheel 20, thereby expanding the application scenarios of the wheel storage unit 10.

[0083] Figure 3 This is a partial enlarged view of the slider provided in an embodiment of this application.

[0084] As one implementation method, refer to Figure 3 As shown, the isolator 210 is rotatably connected to the slider 310. The slider 310 may be provided with a connecting seat 311, and the isolator 210 may be connected to a rotating shaft 213. The rotating shaft 213 may pass through the connecting seat 311 and may rotate relative to the connecting seat 311.

[0085] Thus, when the separator 210 is in the retracted state, it is in a vertical position, occupying little internal space of the support frame 120. When it is necessary to switch the separator 210 to the laying state, the separator 210 can be rotated relative to the connecting seat 311 via the rotating shaft 213 and switched to a horizontal position, thereby separating the upper and lower wheels 20.

[0086] In another embodiment, the isolation member 210 can also be slidably connected to the sliding member 310.

[0087] For example, a slide rail can be provided on the slider 310, and the spacer 210 can be slidably connected to the slide rail and move towards the outside of the support frame 120, thereby freeing up space for storing the lower wheel 20. After the lower wheel 20 is placed, the height of the spacer 210 can be adjusted accordingly, and it can slide into the support frame 120, sandwiching between the two wheels 20.

[0088] Continue to refer to Figure 2 As shown, the base 100 may also include a base plate 130, which is disposed on the inner bottom wall of the support frame 120, and the bottommost wheel 20 is in contact with the base plate 130.

[0089] In this way, by placing the base plate 130 between the support frame 120 and the wheel 20, the wear that may occur between the bottom wheel 20 and the support frame 120 can be reduced, and the storage stability of the wheel 20 can be enhanced.

[0090] As one implementation method, such as Figure 2 As shown, two base plates 130 can be provided, and the two base plates 130 can be connected to both sides of the support frame 120 respectively, corresponding to the isolation component 200. Specifically, the two base plates 130 can be fixedly connected to the inner bottom wall of the support frame 120.

[0091] In this way, the base plate 130 and the separator 210 can use the same structural plate 211, thereby reducing the number of parts and related manufacturing processes in the wheel storage unit 10.

[0092] As another implementation, the base plate 130 can also be configured as a single plate 211 with clearance holes. This configuration increases the contact area between the base plate 130 and the support frame 120, and also better distributes stress onto the support frame 120. The clearance holes allow the guide post 110 to pass through, thus preventing interference.

[0093] For example, a buffer structure 131 may be provided on the side of the base plate 130 facing the isolation member 210. This can reduce the possibility of wear between the wheel 20 and the inner bottom wall of the support frame 120, and can prevent relative sliding between the two. At the same time, it can also buffer the impact of the wheel 20 on the support frame 120.

[0094] Understandably, the buffer structure 131 can be made of the same material as the buffer layer 212, such as nitrile rubber sheet, which can increase the versatility of the parts.

[0095] The following provides a detailed description of the specific structure of the support frame 120 and various possible implementation methods.

[0096] Figure 4 This is a schematic diagram of the structure of the base provided in an embodiment of this application.

[0097] Reference Figure 4 As shown, the support frame 120 includes an upper support frame 121, a lower support frame 122, and legs 123 connecting the corners of the two. It is understood that the spacer 210 can be slidably connected to each leg 123 via a slider 310.

[0098] The lower support frame 122 includes an outer rectangular frame 124 and a diagonal beam 125. The diagonal beam 125 is connected to the diagonal of the outer rectangular frame 124. This results in a simple structure and good stability for the support frame 120. Simultaneously, the diagonal beam 125 provides support for the wheel 20 and further transmits force to the entire support frame 120, thus improving the reliability of the support frame 120.

[0099] Furthermore, the upper support frame 121 can enclose a rectangular opening to facilitate access to the wheel 20.

[0100] Specifically, the outer rectangular frame 124 in both the upper support frame 121 and the lower support frame 122 is provided with four crossbeams 126. The two crossbeams 126 connected to the same leg 123 are respectively connected to the adjacent two side surfaces of the leg 123, and the crossbeams 126 are perpendicular to each other.

[0101] It is understandable that when the wheel storage unit 10 is not equipped with a base plate 130, the wheel 20 can be placed directly on the inclined beam 125, and the force can be transmitted to the entire support frame 120 through the inclined beam 125.

[0102] To ensure that the support frame 120 has sufficient strength, the support frame 120 may be made of high-strength steel.

[0103] When the wheel storage unit 10 is provided with a base plate 130, the base plate 130 can be connected to the upper surface of the inclined beam 125, and the base plate 130 can be fixedly connected to the corner of the outer rectangular frame 124 so that there will be no relative movement between it and the support frame 120, thereby further ensuring the stability of the wheel storage unit 10.

[0104] For example, the support frame 120 may also include a limiting member 127. The limiting member 127 is connected between the upper support frame 121 and the lower support frame 122, and is located on the side of the two opposing spacers 210 that are far apart from each other.

[0105] In this way, when the isolation component 210 switches from the laying state to the storage state, the rotation of the isolation component 210 can be limited by the limiting component 127 to prevent the isolation component 210 from flipping outwards towards the support frame 120 and occupying extra space.

[0106] In one implementation, the support frame 120 may also include a reinforcing member 128.

[0107] The reinforcing member 128 can be connected between the outer rectangular frame 124 and the inclined beam 125, or the reinforcing member 128 can be connected between adjacent inclined beams 125. Alternatively, the reinforcing member 128 can be connected both between the outer rectangular frame 124 and the inclined beam 125 and between adjacent inclined beams 125.

[0108] This further enhances the stability of the wheel storage unit 10, preventing it from tipping over or breaking due to excessive weight of the wheel 20.

[0109] To further improve the strength of the support frame 120, the support frame 120 may also include a support member 129.

[0110] The support member 129 can be connected between the support leg 123 and the upper support frame 121, or between the support leg 123 and the lower support frame 122. Alternatively, the support member 129 can be connected both between the support leg 123 and the upper support frame 121 and between the support leg 123 and the lower support frame 122.

[0111] For example, the support member 129 can be a stiffening plate with weight-reducing holes. One side of the stiffening plate is connected to the outer wall of the crossbeam 126, and the other side is connected to the outer wall of the support leg 123. In this way, the deformation resistance of the support frame 120 can be further enhanced, making the wheel storage unit 10 more reliable.

[0112] In one implementation, a positioning element 400 may be provided at the top of the support frame 120, and a positioning hole may be provided at the bottom of the support frame 120. Alternatively, a positioning element 400 may be provided at the top of the guide column 110, and a positioning hole may be provided at the bottom of the inclined beam 125 of the support frame 120. For example, the positioning element 400 may be a positioning pin.

[0113] It is understood that the positioning element 400 can be set on the crossbeam 126 of the upper support frame 121 or on the top of the support leg 123, and the positioning hole can be set on the crossbeam 126 of the lower support frame 122 or on the bottom of the support leg 123. No limitation is made here.

[0114] In this way, the wheel storage units 10 can be stacked by the cooperation of the positioning hole and the positioning part 400, thereby further saving space.

[0115] Based on this, a lifting lug 1231 can be connected to the outer wall of the outrigger 123. When multiple wheel storage units 10 are stacked together, the lifting equipment can separate the multiple wheel storage units 10 through the lifting lug 1231.

[0116] This application embodiment also provides a wheel storage stacking module, which includes at least two of the above-described wheel storage units 10. Each wheel storage unit 10 can be stacked along the height direction of the wheel storage unit 10.

[0117] In this way, by stacking the wheel storage units 10 together, the storage space for the wheels 20 can be further saved, and the space utilization rate can be improved.

[0118] For example, the positioning member 400 of one of the adjacent wheel storage units 10 can be connected to the positioning hole of the other. In this way, the wheel storage units 10 can be stably stacked, and the wheel storage units 10 can also be flexibly separated.

[0119] The usage process of the wheel storage unit 10 and wheel storage stacking module provided in this application embodiment is as follows:

[0120] 1. Storage process:

[0121] (1) Spacing adjustment of the isolation parts: Based on the rim width of the wheel 20 (rim width tolerance range ±5mm), adjust the installation position of the sliding part 310 on the support leg 123 through the fixing part 320 (pin-type positioning and locking mechanism) to determine the spacing of the isolation parts 210 and ensure that the axial clearance of different specifications of wheels 20 is adapted.

[0122] (2) Pre-positioning of isolation components: By rotating the shaft 213 of the isolation component 210, the upper isolation component 210 is switched from the laying state (the angle between the load-bearing surface of the isolation component 210 and the horizontal plane is 0°) to the storage state (the angle between the shelf and the beam 126 is 90°), forming a hoisting operation space.

[0123] (3) Wheel hoisting and positioning: The wheel 20 is hoisted to the wheel storage unit 10 using the overhead crane hoist (wheel 20 gripper), the position of the wheel hub hole of the wheel 20 is adjusted to be basically aligned with the guide column 110, and then slowly lowered onto the lower support frame 122 or the base plate 130.

[0124] (4) Reset the isolation component: Reset the isolation component 210, which was originally in the storage state, to the horizontal position to form the next storage plane, which is in contact with the upper surface of the wheel 20.

[0125] 2. Retrieval process:

[0126] (1) Taking the upper wheel: Use the overhead crane to clamp the rim of the uppermost wheel 20 and lift the wheel 20 vertically until it is separated from the guide column 110.

[0127] (2) Dynamic isolation component switching: Before taking the middle layer wheel 20, the upper layer isolation component 210 is switched from the laying state to the storage state through the rotation shaft 213 of the isolation component 210, releasing the operating space of the lifting tool, and then the middle wheel 20 is lifted.

[0128] (3) Wheel transfer protection: During the handling process, the contact surface between the wheel 20 and the isolation piece 210 is softly buffered by the buffer layer 212, and the contact surface between the wheel 20 and the base plate 130 is softly buffered by the buffer structure 131, so as to avoid mechanical scratches on the wheel flange surface.

[0129] 3. Palletizing process:

[0130] When the lower wheel storage unit 10 is fully loaded, the upper empty wheel storage unit 10 is hoisted by an overhead crane. The positioning pins on the top of the lower wheel storage unit 10 and the positioning holes of the upper wheel storage unit 10 are used to achieve quick centering and stacking. The upper storage unit can store and retrieve the wheels 20 according to the storage and retrieval process.

[0131] The wheel storage unit 10 and wheel storage stacking module provided in this application have the following beneficial effects:

[0132] (1) Based on the number of wheels 20 to be stored and the mass of the wheels 20, a force analysis is carried out on the force path of the wheel storage unit 10. Even when the wheels 20 are fully loaded, the strength redundancy of the wheel storage unit 10 is sufficient to ensure the safety and stability of the storage of the train wheels 20.

[0133] (2) The flip-out isolation component 210 structure can facilitate the access of the wheels 20 and also separate each wheel 20, thus protecting the wheels 20.

[0134] (3) The wheel storage unit 10 can store wheels 20 of different diameters, which improves the versatility of the wheel storage unit 10.

[0135] (4) The isolation member 210 of the wheel storage unit 10 can be moved up and down by the sliding member 310, which can adapt to the rim width of different wheels 20.

[0136] (5) The wheel storage unit 10 is equipped with positioning pins and positioning holes, which can realize stacking between storage racks, further improving space utilization and optimizing storage efficiency. It can be adapted to both overhead crane transport and forklift transport. It is particularly suitable for railway vehicle maintenance workshops, warehousing centers and other scenarios.
