[0001] This utility model belongs to the field of vehicle axle storage and transportation technology, specifically relating to a detachable vehicle axle turnover rack. Background Technology
[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.
[0003] In the transportation of vehicle axles, the storage and transport stages are crucial. Traditional vehicle axle turnover racks mostly adopt a fully welded fixed structure, which has many drawbacks: First, fully welded fixed turnover racks are large in size, occupy a lot of space, require a large area for storage, and are inconvenient to transport, increasing transportation costs; second, fully welded fixed turnover racks have poor versatility, often requiring different specifications of turnover racks for different models and sizes of axles, which not only increases equipment purchase costs but also brings many inconveniences to management and use; finally, in environments with limited space, such as workshops, fully welded fixed turnover racks lack flexibility and are difficult to quickly adjust and optimize their layout according to actual work needs.
[0004] The prior art discloses a detachable turnover rack, including a base frame and a mating frame, which are detachable. The base frame includes a base frame and an upright frame fixedly connected to the base frame.
[0005] The above solution allows multiple underframes to be stacked after the mounting bracket is removed from the underframe; however, the following drawbacks still exist: the underframe dimensions are fixed, and stacking multiple underframes in sequence will still occupy a large space, requiring a large area for storage; in addition, the fixed underframe dimensions mean that a different underframe needs to be made for each height and each width for different models and sizes of axles, resulting in poor versatility. Utility Model Content
[0006] In view of this, the purpose of this utility model is to provide a detachable axle turnover rack. The complete disassembly of the turnover rack can solve the problems of existing technologies where the base frame is stacked and stored, which still occupy a lot of space and have poor versatility.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A detachable axle turnover frame is provided, including a first upright and a second upright of the same size, and multiple cross braces can be detachably connected between the first upright and the second upright;
[0009] Multiple sets of socket tubes are fixed at the bottom of the first and second uprights, and multiple socket tubes in the same set are evenly fixed on the first or second uprights at intervals along the vertical direction.
[0010] Each cross brace consists of multiple struts, with short struts fixed between the struts; the number of struts in a cross brace is equal to the number of socket tubes in the same group;
[0011] The socket tubes are vertically installed on the opposite surfaces of the first and second uprights. When the first and second uprights are installed opposite each other, the positions of the corresponding socket tubes are aligned. The two ends of the cross brace are inserted into the socket tubes of the first or second upright. Bolt holes are opened on both ends of the cross brace and on the socket tubes for bolt fasteners to be inserted.
[0012] Preferably, the length of the cross brace is varied, and the height of the first and second uprights is varied to accommodate different specifications of axles. The appropriate cross brace is selected and connected to the first and second uprights according to the corresponding specifications of the axle.
[0013] Preferably, at least two bolt holes are provided on each end of the strut and on each socket tube.
[0014] Preferably, a pin hole is provided at the end of the bolt fastener connecting the nut, and the pin is inserted after the nut is connected.
[0015] Preferably, either the first or second upright includes a crossbeam, with columns fixedly connected vertically at both ends of the crossbeam. The connection between the crossbeam and the column is located at a predetermined distance above the bottom of the column, thereby forming a support leg at the bottom of the column.
[0016] Preferably, a support leg is added between the columns of the first or second upright, and the top of the support leg is fixedly connected to the crossbeam.
[0017] Preferably, the socket tube is fixed on the support leg, with a set of socket tubes fixed on each support leg, and the bottom socket tube is set at a certain distance from the ground.
[0018] Preferably, the spacing between the socket tubes is equal to the length of the short rod.
[0019] Preferably, diagonal bracing is provided between the columns of the first frame.
[0020] Preferably, a foot pad is provided at the bottom of each leg.
[0021] Compared with the prior art, the advantages and positive effects of this utility model are:
[0022] This invention fixes multiple sets of socket tubes at the bottom of the first and second uprights. The socket tubes are vertically arranged on the opposite surfaces of the first and second uprights. The two ends of the cross brace are inserted into the socket tubes of the first or second upright, and then fastened with bolts to form a detachable axle turnover frame. After disassembly, the first and second uprights are aligned and the cross brace is placed on one side. Compared with the stacking of the base frame in the prior art, it can save more space. In addition, the cross brace in this invention has various lengths, and the first and second uprights have various heights to adapt to different specifications of axles. The cross brace of the appropriate length can be selected and connected with the first and second uprights of the appropriate height according to the corresponding axle specifications. Compared with the prior art, which makes a base frame for each height and a base frame for each width, this embodiment can make the cross brace according to the width and the first and second uprights according to the height, and combine them as needed, which has better versatility.

[0029] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.
[0030] The present invention will now be described in detail with reference to the accompanying drawings.
[0031] This embodiment discloses a detachable axle turnover rack, such as Figure 1As shown, it includes a first upright 1 and a second upright 2 of the same size, with multiple cross braces 3 detachably connected between the first upright 1 and the second upright 2. Figure 1 , Figure 2 As shown, multiple sets of socket tubes 4 are fixed to the bottom of both the first upright 1 and the second upright 2. The socket tubes 4 are perpendicular to the first upright 1 or the second upright 2. There are multiple socket tubes 4 in each set. The multiple socket tubes 4 in the same set are fixed to the first upright 1 or the second upright 2 at equal intervals along the vertical direction. The cross brace 3 is inserted into the socket tube 4 to connect the first upright 1 and the second upright 2.
[0032] It should be noted that the first upright 1 and the second upright 2 are arranged opposite each other, and the socket tube 4 is arranged on the surface on which the first upright 1 and the second upright 2 are arranged opposite each other. When the first upright 1 and the second upright 2 are arranged opposite each other, the positions of the opposite socket tubes 4 are corresponding, so that the cross brace 3 is perpendicular to the first upright 1 and the second upright 2, ensuring the stability of the force.
[0033] like Figure 1 , Figure 2 As shown, each horizontal brace 3 includes multiple support rods 31, and short rods 32 are fixedly connected between the multiple support rods 31; the number of support rods 31 in the horizontal brace 3 is equal to the number of socket tubes 4 in a group. In this embodiment, each horizontal brace 3 includes two support rods 31, and the number of socket tubes 4 in each group is two. The two ends of the two support rods 31 of a horizontal brace 3 are respectively inserted into the socket tubes 4 corresponding to the first upright 1 and the second upright 2.
[0034] like Figure 1 , Figure 2 As shown, bolt holes of equal number and corresponding positions are opened at both ends of each support rod 31 and on the socket tube 4. After the support rod 31 is inserted into the socket tube 4, the bolt holes are exactly aligned. The bolt fasteners 5 are inserted into the bolt holes and tightened. Multiple cross braces 3 are connected together with the first upright 1 and the second upright 2 to form a detachable vehicle axle turnover frame.
[0035] In this embodiment, multiple cross braces 3 are removed from the first upright 1 and the second upright 2, the first upright 1 and the second upright 2 are aligned and placed, and the cross braces 3 are placed on one side, which can save more space compared with the base frame of the prior art.
[0036] In this embodiment, the cross brace 3 is a horizontally arranged long strip structure, and its two ends are connected to the socket tube 4 by bolt fasteners 5 to form a stable support frame.
[0037] In this embodiment, the length of the cross brace 3 is varied, and the height of the first upright 1 and the second upright 2 is varied to adapt to different specifications of axles. The cross brace 3 of the appropriate length and the first upright 1 and the second upright 2 of the appropriate height can be selected and connected according to the corresponding specifications of the axle. Compared with the prior art, which makes a base frame for each height and a base frame for each width, this embodiment can make the cross brace according to the width and the first upright 1 and the second upright 2 according to the height, and combine them as needed, which has better versatility.
[0038] It should be noted that, in order to increase the connection stability of the cross brace 3, multiple short rods 32 can be evenly arranged between the support rods 31.
[0039] In this embodiment, as Figure 2 As shown, at least two bolt holes are provided at the end of each strut 31 and on each socket tube to ensure the stable connection between the strut 31 and the socket tube 4, thereby ensuring the stable connection between the cross brace 3 and the socket tube 4.
[0040] In some implementations, a pin hole can be made at one end of the bolt fastener connecting the nut. After the nut is connected, a pin is inserted into the pin hole to prevent the nut from loosening and falling off the bolt, which would cause the connection between the cross brace 3 and the socket tube 4 to fail.
[0041] like Figure 1 , Figure 2 As shown, both the first upright 1 and the second upright 2 include a crossbeam 12, with uprights 11 vertically fixed to both ends of the crossbeam 12. The connection between the crossbeam 12 and the upright 11 is located at a predetermined distance above the bottom of the upright, thus forming a support leg 13 at the bottom of the upright 11. The support leg 13 is supported on the ground, creating a gap between the turnover rack and the ground, facilitating forklift loading and transportation. In this embodiment, the connection between the crossbeam and the upright is located 23 to 26 centimeters above the bottom of the upright, preferably 25 centimeters.
[0042] like Figure 1 , Figure 2 As shown, to increase the overall stability of the turnover frame, support legs 13 are added between the columns 11 of the first upright 1, and the top of the support legs 13 is fixedly connected to the bottom of the crossbeam 12; support legs 13 are also added at the corresponding positions of the second upright. In this embodiment, the distance between the support legs 13 and the adjacent column 11 is equivalent to one-fifth to one-quarter of the overall length of the crossbeam 12.
[0043] like Figure 1 , Figure 2As shown, the socket tube 4 is fixed to the support leg 13, that is, a set of socket tubes 4 is fixed on each support leg 13, and the bottom socket tube 4 is set at a certain distance from the ground, so as to ensure that after the cross brace 3 is connected to the socket tube 4, the bottom support rod 31 is at a certain height from the ground, which facilitates forklift loading and transportation. In this embodiment, the bottom socket tube is nine to ten centimeters from the ground.
[0044] In this embodiment, the length of the short rod 32 is equal to the spacing between the socket tubes 4, ensuring that the support rod 31 of the cross brace 3 can be inserted into the corresponding socket tube 4.
[0045] like Figure 1 , Figure 2 As shown, diagonal bracing 14 is provided between the columns 11 of the first support frame 1. Specifically, the diagonal bracing 14 includes two diagonal rods, which are fixedly connected at their centers to form an X shape. The top ends of the two diagonal rods are fixedly connected to the tops of the two columns 11 respectively, and the bottom ends of the two diagonal rods are fixedly connected to the connection between the column and the crossbeam respectively.
[0046] It should be explained that each horizontal brace 3 and each leg 13 form a frame. In this embodiment, by setting three horizontal braces 3, it is equivalent to setting three frames between the first upright 1 and the second upright 2. Stable support can be formed between the first upright 1 and the second upright 2. However, in the other direction, that is, between the columns of the same upright, only the crossbeams provide support, which lacks certain constraints. Therefore, diagonal braces are set on the first upright to increase the stability of the entire turnover frame.
[0047] In some implementations, a foot pad can be provided at the bottom of each outrigger 13 to reduce noise when the outrigger 13 contacts the ground.
[0048] In this embodiment, the fixed connection between the crossbeam and the column, the fixed connection between the socket tube and the crossbeam, column, or leg, the fixed connection between the diagonal brace and the column or crossbeam, the fixed connection between the crossbeam and the short rod, and the fixed connection between the leg and the crossbeam are all achieved by welding.
[0049] like Figure 3 As shown, a stress analysis under simulated full-load conditions was performed on the detachable axle turnover frame in this embodiment. The frame structure composed of columns, beams, cross braces, and diagonal braces has small stress concentration areas at key connection points, proving that the structural design can effectively distribute the load and avoid local overload. The pressure on the contact surface is distributed in a ring-shaped diffusion pattern, which not only avoids excessive local stress leading to deformation or damage, but also ensures the stability of the turnover frame when carrying the axle.
[0050] In this embodiment, the detachable design does not weaken the overall strength; the components are tightly connected and work together to bear loads. This allows the turnover rack to maintain structural integrity during frequent disassembly and assembly, satisfying both flexibility and ensuring operational safety through a scientifically designed force transmission path.
[0051] In this embodiment, the diagonal bracing enhances the resistance to tilting and deformation, maintaining structural stability even when bearing heavy loads such as axles. Whether in static storage or dynamic turnover, the excellent load-bearing performance ensures the safety of the axles, and the bracing is flexible in assembly and disassembly, convenient in transportation and storage, and combines practicality with mechanical reliability.
[0052] Overall, this detachable axle turnover rack has good load-bearing strength and can meet the storage needs of axles of different heights and widths. It has broad application prospects in the fields of automobile manufacturing and repair, and provides reliable and stable support for the storage, transportation and assembly of axles.
[0053] The detachable axle turnover rack in this embodiment is easy to maintain and solves the problems of traditional turnover racks that are not detachable, occupy a large area, and have poor versatility. The detachable axle turnover rack in this embodiment can be well applied to the production and turnover scenarios of axles.
[0054] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
