Description

Technical Field

[0001] This utility model relates to the field of wheel and axle production technology, and more specifically, to a wheel and axle storage bracket. Background Technology

[0002] Train wheelsets are the core components of the running gear of railway vehicles. They are typically composed of wheelsets, axle box assemblies, suspension systems, braking devices, and transmission components. The core is the high-strength alloy steel axle connected to the wheels on both sides (including the wheel flanges that provide guidance and the treads that contact the rails) through an interference fit. The two ends of the axle are supported in sealed axle boxes by high-precision bearings and are connected to the bogies through a series of suspension and shock-absorbing elements. The power wheelset is also equipped with a gearbox and coupling to transmit traction force. Brake discs, axle temperature sensors, and lubrication interfaces work together to ensure the safety and stability of high-speed, heavy-load operation.

[0003] Currently, during the production and storage of wheel axles, due to their status as long, precision components, typically reaching 2-3 meters in length and weighing several tons, wheel axles must be placed on specialized supports to ensure verticality and surface finish. However, existing storage supports are mostly simple in structure, only allowing for single-layer flat arrangement of wheel axles, resulting in low storage density per unit area, insufficient warehouse capacity utilization, and significant space occupation in the production workshop.

Each first stop block group and one second stop block group are arranged opposite each other in the transverse direction, and the spacing between them is adapted to the wheel axle length. Each pair of opposite first stop block groups and second stop block groups constitutes a lower storage position for placing the wheel axle.

[0007] The second longitudinal beam is provided with multiple first support feet, and each first support foot is provided with a third stop block group.

Then, L1=L2=2D and D>d1+d2 / 2, where d1 is the maximum outer diameter of the wheel of the axle and d2 is the maximum outer diameter of the axle.

[0011] Optionally, the distance between the left beam and the right beam is greater than the wheel thickness of the axle, and multiple crossbeams connect the left beam and the right beam.

[0012] Optionally, both the left beam and the right beam are U-shaped channel beams, and the left beam and the right beam form a symmetrical layout with the channel openings facing away from each other.

Each row of the first support legs is spaced apart along the axial direction of the beam body, and the two rows of the first support legs are staggered along the axial direction of the beam body.

[0014] Optionally, the beam body is provided with two rows of the third stop block groups through two rows of the first support legs. The spacing of the third stop block groups in one row is L3, and the spacing of the third stop block groups in the other row is L4. The axial spacing of the third stop block groups in both rows on the beam body is S, which satisfies L3=L4=2S and S>d1+d2 / 2, where d1 is the maximum outer diameter of the wheel of the axle, and d2 is the maximum outer diameter of the axle.

[0015] Optionally, the first support foot includes a top plate, a bottom plate, a vertical plate, and a rib plate. The top plate is used to set the third stop block group, and the bottom plate is used to connect the second longitudinal beam. The top plate and the bottom plate are arranged in parallel. The top plate, the bottom plate, and the vertical plate are connected in a U-shaped structure. The rib plate is set on the inner side wall of the U-shaped structure and is perpendicularly connected to the top plate, the bottom plate, and the vertical plate.

[0016] Optionally, the first block group includes two blocks spaced apart.

[0032] like Figure 1-5As shown in the figure, an embodiment of the present invention provides a wheel axle storage bracket, including a first longitudinal beam 1, a second longitudinal beam 2, a third longitudinal beam 3, and a fourth longitudinal beam 4 arranged in parallel in sequence; the first longitudinal beam 1 is provided with a plurality of first stop block groups 51, and the third longitudinal beam 3 is provided with a plurality of second stop block groups 52. Each first stop block group 51 and a second stop block group 52 are arranged opposite each other in the transverse direction, and the spacing between them is adapted to the length of the wheel axle 6. Each pair of opposite first stop block groups 51 and second stop block groups 52 constitutes a lower storage position for placing the wheel axle 6; the second longitudinal beam 2 is provided with a plurality of first supports Each first support foot 7a is provided with a third stop block group 53. The fourth longitudinal beam 4 is provided with multiple second support feet 7b, and each second support foot 7b is provided with a fourth stop block group 54. Each third stop block group 53 and a fourth stop block group 54 are arranged opposite each other in the transverse direction, and the spacing is adapted to the length of the wheel axle 6. Each pair of opposite third stop block groups 53 and fourth stop block groups 54 constitutes an upper storage position for placing the wheel axle 6. The height of the upper storage position is higher than that of the lower storage position, and the vertical projection of each upper storage position is located between two adjacent lower storage positions.

[0033] In this embodiment, the basic frame structure of the wheel axle storage bracket consists of four parallel longitudinal beams, namely, the first longitudinal beam 1, the second longitudinal beam 2, the third longitudinal beam 3, and the fourth longitudinal beam 4. The first longitudinal beam 1, the second longitudinal beam 2, the third longitudinal beam 3, and the fourth longitudinal beam 4 are laid longitudinally, i.e. Figure 1 The Y direction is the horizontal direction, which is the direction that is horizontal and vertical, i.e., the X direction in the figure.

[0034] The first longitudinal beam 1 is usually provided with a plurality of first stop blocks 51 at intervals along its axial direction, and the third longitudinal beam 3 is usually provided with a plurality of second stop blocks 52 at intervals along its axial direction. Each first stop block 51 and the corresponding second stop block 52 are arranged facing each other in the horizontal direction, and the interval distance is adapted to the length of the wheel axle 6, forming a lower storage position for supporting the two ends of the wheel axle 6. That is, each pair of facing first stop blocks 51 and second stop blocks 52 constitutes a lower storage unit.

[0035] The second longitudinal beam 2 is typically provided with multiple first support legs 7a spaced apart along its axial direction, and a third stop block group 53 is provided at the top of each first support leg 7a; the fourth longitudinal beam 4 is typically provided with multiple second support legs 7b spaced apart along its axial direction, and a fourth stop block group 54 is provided at the top of each second support leg 7b; each third stop block group 53 and the corresponding fourth stop block group 54 are arranged facing each other in the horizontal direction, and the spacing is adapted to the length of the wheel axle 6, forming an upper storage position for supporting the two ends of the wheel axle 6, that is, each pair of facing third stop block groups 53 and fourth stop block groups 54 constitutes a lower storage unit.

[0036] The upper storage position is higher than the lower storage position, and the vertical projection of each upper storage position is located between two adjacent lower storage positions, thus forming a double-layer storage structure that is staggered in the vertical direction and alternately distributed in the horizontal direction. This greatly increases the density of wheel axles 6 stored per unit area, improves warehouse capacity utilization, and makes the wheel axle 6 storage area occupy less space in the production workshop.

[0037] Optionally, such as Figure 1 As shown, the first longitudinal beam 1 includes a left beam 11 and a right beam 12 arranged in parallel. The left beam 11 and the right beam 12 are respectively provided with a plurality of first stop blocks 51 at intervals along their respective axial directions, and the first stop blocks 51 on the left beam 11 and the right beam 12 are staggered and distributed along the axial direction of the first longitudinal beam 1.

[0038] In this optional embodiment, the first longitudinal beam 1 is designed as a parallel double-beam structure consisting of a left beam 11 and a right beam 12, which has a stronger load-bearing capacity than a single-beam structure. Moreover, the staggered arrangement of baffle groups on the left beam 11 and the right beam 12 staggers the adjacent lower storage positions, allowing for more baffle groups to be set within the same longitudinal beam length, thus greatly increasing the storage density.

[0039] Optionally, such as Figure 1 and Figure 5 As shown, the spacing of the first stop block group 51 on the left beam 11 is L1, and the spacing of the first stop block group 51 on the right beam 12 is L2. The spacing of the first stop block group 51 on the left beam 11 and the right beam 12 along the axial direction of the first longitudinal beam 1 is D. Then, L1=L2=2D and D>d1+d2 / 2, where d1 is the maximum outer diameter of the wheel of the axle 6 and d2 is the maximum outer diameter of the axle of the axle 6.

[0040] In this optional embodiment, the first block group 51 is evenly spaced L1 on the left beam 11, and the second block group 52 is evenly spaced L2 on the right beam 12. The first block group 51 and the second block group 52 are also evenly spaced D along the axial direction of the first longitudinal beam 1, so that the lower storage position is arranged in a double-row staggered and orderly manner, which is beneficial for robotic grippers or manual handling.

[0041] In addition, D > d1 + d2 / 2, where d1 is the maximum outer diameter of the wheel of axle 6, which is generally the outer diameter of the rim; d2 is the maximum outer diameter of the axle of axle 6, ensuring that the axles 6 placed in the two rows of lower storage positions have a safe distance in the arrangement direction.

[0042] Optionally, the distance between the left beam 11 and the right beam 12 is greater than the wheel thickness of the axle 6, and multiple crossbeams 13 are connected between the left beam 11 and the right beam 12.

[0043] In this optional embodiment, the distance between the left beam 11 and the right beam 12 is greater than the wheel thickness of the axle 6, ensuring a safe distance between adjacent wheels on the two rows of lower storage positions along the axial direction of the axle 6. Multiple crossbeams 13 are provided between the left beam 11 and the right beam 12 to increase the overall structural strength of the first longitudinal beam 1.

[0044] Optionally, such as Figure 1 As shown, both the left beam 11 and the right beam 12 are U-shaped channel beams, and the left beam 11 and the right beam 12 form a symmetrical layout with the channel openings facing away from each other.

[0045] In this optional embodiment, the U-shaped channel beam structure is simple and easy to manufacture. Moreover, the symmetrical layout of the slots facing away from each other can withstand a greater load in the vertical direction to ensure stable support for the wheel axle 6 of the lower storage position.

[0046] Optionally, such as Figure 1 As shown, the third longitudinal beam 3 has the same structure as the first longitudinal beam 1.

[0047] In this optional embodiment, the third longitudinal beam 3 has the same structure as the first longitudinal beam 1, which is also a parallel double-beam structure, reducing manufacturing costs. In addition, the first stop block group 51 and the second stop block group 52 also have the same structure, so that the third longitudinal beam 3 and the structure arranged on it can overlap with the first longitudinal beam 1 and the structure arranged on it after translation.

[0048] Optionally, such as Figure 1 As shown, the second longitudinal beam 2 includes a beam body, on which two rows of first support legs 7a are arranged in parallel. Each row of first support legs 7a is spaced apart along the axial direction of the beam body, and the two rows of first support legs 7a are staggered along the axial direction of the beam body.

[0049] In this optional embodiment, two rows of first support legs 7a are arranged in parallel on the beam body, and the two rows of first support legs 7a are staggered in the axial direction of the beam body, so that adjacent upper storage positions are staggered to the left and right, and more block groups can be set within the same length, which greatly improves the storage density.

[0050] Optionally, such as Figure 1 and Figure 5 As shown, the main beam body is provided with two rows of third stop block groups 53 through two rows of first support legs 7a. The spacing of the third stop block groups 53 in one row is L3, and the spacing of the third stop block groups 53 in the other row is L4. The axial spacing of the two rows of third stop block groups 53 in the main beam body is S. Then, L3=L4=2S and S>d1+d2 / 2, where d1 is the maximum outer diameter of the wheel of the axle 6 and d2 is the maximum outer diameter of the axle of the axle 6.

[0051] In this optional embodiment, the third block group 53 is evenly spaced L3 on the beam body, and the fourth block group 54 is evenly spaced L4 on the beam body. Furthermore, the third block group 53 and the fourth block group 54 are also evenly spaced S along the axial direction of the beam body, thereby making the upper storage position arranged in a double-row staggered and orderly manner, which is beneficial for robotic grippers or manual handling.

[0052] Additionally, S > d1 + d2 / 2, where d1 is the maximum outer diameter of the wheel of axle 6 and d2 is the maximum outer diameter of the axle of axle 6, ensuring a safe distance between the axles 6 placed in the two rows of upper storage positions in the arrangement direction. Typically, the interval S is the same as the interval D mentioned above.

[0053] Optionally, the spacing between the two rows of third stop blocks 53 on the main beam is greater than the wheel thickness of the axle 6, ensuring that the axles 6 placed on the two upper storage positions have a safe distance between two adjacent wheels along the axle 6 axis.

[0054] Optionally, the beam body has a rectangular cross-section, and a row of first support feet 7a is provided on both sides of the top surface of the beam body. The rectangular cross-section beam has high structural strength, and the flat top surface facilitates the arrangement of two rows of first support feet 7a.

[0055] Optionally, the height of the second longitudinal beam 2 is lower than the axle height of the wheel axle 6 placed in the lower storage position, so that the wheel axle 6 placed in the lower storage position can cross the second longitudinal beam 2.

[0056] Optionally, the fourth longitudinal beam 4 and the second longitudinal beam 2 have the same structure, both being rectangular cross-section beams, and both having two rows of second support legs 7b arranged on the top surface. Furthermore, the first support legs 7a and the second support legs 7b have the same structure, reducing manufacturing costs. That is, after translation, the second longitudinal beam 2 and the structure arranged on it can overlap with the fourth longitudinal beam 4 and the structure arranged on it.

[0057] Optionally, the first support foot 7a includes a top plate 71, a bottom plate 72, a vertical plate 73, and a rib plate 74. The top plate 71 is used to set the third stop block group 53, and the bottom plate 72 is used to connect the second longitudinal beam 2. The top plate 71 and the bottom plate 72 are arranged in parallel. The top plate 71, the bottom plate 72, and the vertical plate 73 are connected in a U-shaped structure. The rib plate 74 is set on the inner side wall of the U-shaped structure and is perpendicularly connected to the top plate 71, the bottom plate 72, and the vertical plate 73.

[0058] In this optional embodiment, the first support leg 7a is composed of a top plate 71, a bottom plate 72, a vertical plate 73, and a rib plate 74, which has a simple structure and provides stable support. Furthermore, the vertical plate 73 of the first support leg 7a is arranged flush with one side plate of the rectangular cross-section beam body in the transverse direction. The top plate 71, bottom plate 72, and vertical plate 73 are all rectangular plates, with the width of the top plate 71 in the transverse direction being smaller than that of the bottom plate 72, and the rib plate 74 is a trapezoidal plate.

[0060] Optionally, the first block group 51 includes two blocks spaced apart.

[0061] In this optional embodiment, the two stops can limit the wheel of the axle 6 placed between the two stops to form a storage position for the axle 6. Furthermore, the first stop group 51, the second stop group 52, the third stop group 53, and the fourth stop group 54 have the same structure, each including two stops spaced apart. The two stops in each stop group can be designed with an adjustable spacing to accommodate axles 6 of different sizes, and an arc-shaped limiting surface adapted to the tread surface of the axle 6 can be provided on the stops.

[0062] Optionally, the first longitudinal beam 1, the second longitudinal beam 2, the third longitudinal beam 3 and the fourth longitudinal beam 4 are all straight beams and are laid flat on the ground.

[0063] Optionally, the first longitudinal beam 1, the second longitudinal beam 2, the third longitudinal beam 3, and the fourth longitudinal beam 4 are all fixed to the ground with anchor bolts, which is simple to fix and easy to install.

[0064] Optionally, the first storage position and the second storage position are both horizontally supported and placed with the wheel axle 6, and all the first storage positions are at the same height, and all the second storage positions are at the same storage height, so as to form a double-layer storage structure.

[0065] Optionally, such as Figure 5 As shown, the axial distance L5 between the adjacent wheel axles 6 placed in the lower storage position and the upper storage position satisfies: L5>d1+d2 / 2, where d1 is the maximum outer diameter of the wheel of wheel axle 6 and d2 is the maximum outer diameter of the axle of wheel axle 6, so that when wheel axle 6 is placed in the lower storage position, the top of its axle maintains a safe distance from the wheel of wheel axle 6 in the upper storage position.

[0066] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
