Description

Technical Field

[0001] This utility model belongs to the technical field of axle placement racks, specifically relating to a placement rack for axle transportation. Background Technology

[0002] In vehicle manufacturing and maintenance, axles, as critical load-bearing and transmission components, require frequent movement and temporary storage in factory workshops or during logistics transportation. To ensure safety and efficiency during transportation, robust axle racks with limiting functions are typically used to position and support the axles. However, most existing axle racks are simple in structure and have limited functionality, making them limited in adapting to axles of different sizes.

[0003] Currently, most widely used storage racks rely on fixed slots or a single type of support structure to restrict the axle. These racks typically cannot be flexibly adjusted according to the axle length, resulting in ineffective restraint at both ends of the axle. This makes the axle prone to axial movement during transport, posing a significant safety hazard. Furthermore, some storage racks use rigid contact structures in the support areas, failing to effectively reduce frictional resistance during loading and unloading, leading to difficulties in manual handling, especially when the axle is placed in the internal support slot, making pushing and pulling inconvenient and impacting actual efficiency.

[0004] In addition, traditional racks are not very adaptable to axles of different diameters. When changing axle models, it is often necessary to replace the entire rack or additional adjustment parts, which is cumbersome and has poor versatility, making it difficult to meet the needs of assembly lines or multi-model parallel operation scenarios. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a placement rack for axle transportation. It can realize a flexible structure, stable support, reliable positioning and easy operation of axle transportation placement device, so as to improve the safety of transportation process and the convenience of loading and unloading.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a placement rack for transporting axles, comprising a movable base frame, the inner side of which is hollow, and a movable frame symmetrically and slidably mounted on the upper side of which axle is mounted. Multiple crossbeams are horizontally arranged on the inner side of the movable frame, and V-shaped grooves for placing axles are evenly opened on the upper surface of the crossbeams.

[0007] The crossbeam has an installation groove inside, and multiple V-shaped grooves are horizontally connected through the installation groove. A lifting beam is slidably installed inside the crossbeam, and a support roller is rotatably installed on the top of the lifting beam. The support roller supports the axle when picking up or putting down the axle.

[0008] A rotating shaft is uniformly mounted on one side surface of the mobile base frame. The rotating shaft is positioned below a V-groove, and a stop bar for limiting the end of the axle is provided on one side of the rotating shaft.

[0009] Furthermore, rollers are symmetrically mounted on both sides of the bottom of the mobile base, and fixed rods are symmetrically arranged on the inner side of the mobile base. A bidirectional screw is rotatably mounted at the center of the inside of the mobile base, and the bidirectional screw is placed between the two fixed rods. A slider is provided at the bottom of the mobile base, and the slider slides on the surface of the two fixed rods and is screwed onto the bidirectional screw.

[0010] Furthermore, a threaded rod is rotatably mounted on the lower inner side of the mounting groove, one end of the threaded rod passing through the side of the movable frame, and a knob is provided at the end of the threaded rod.

[0011] Furthermore, the bottom of the lifting beam is uniformly provided with extrusion cone blocks, a moving block is horizontally slidably installed inside the mounting groove, the moving block is screwed onto the threaded rod, and the upper surface of the moving block is uniformly provided with inclined blocks, which are in contact with the extrusion cone blocks.

[0012] Furthermore, the surface of the movable frame is uniformly provided with positioning holes, which are located directly above the rotating shaft. A sliding bolt is slidably installed on the surface of the stop bar, and the end of the sliding bolt is adapted to the internal size of the positioning hole.

[0013] Furthermore, a pull rod is provided at the end of the bolt away from the positioning hole. The pull rod passes through the stop bar, and a spring is sleeved on the surface of the pull rod. The spring is placed inside the stop bar, and the spring applies a force to the bolt in the direction of the positioning hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, by setting a bidirectional screw, slider and fixed rod structure inside the mobile base frame, and establishing a symmetrical adjustment mechanism between the two mobile frames, the user can adjust the distance between the two mobile frames according to the axle length, thereby ensuring that both ends of the axle are always in a limited state, effectively avoiding the problem of axial movement of the axle during transportation, and improving the overall transportation stability.

[0016] In this invention, multiple V-groove structures are provided on the surface of the crossbeam of the mobile frame, which can adaptively fit and support according to the diameter of the axle. This not only enhances the compatibility with axles of different specifications, but also improves the stability when the axle is placed, thus solving the defects of existing devices that have a narrow range of axle size adaptability and poor support effect.

[0017] In this invention, a lifting beam is set below the V-groove, and a rotatable support roller is installed on it. The lifting and lowering of the support roller is achieved by using a slanted block pressing cone block structure in conjunction with a threaded rod drive method. This raises the support position of the axle during the loading and unloading process, reduces the direct friction between the axle and the V-groove, effectively reduces the resistance of the axle during loading and unloading, improves the convenience of manual operation, and overcomes the problem of difficult operation caused by high frictional resistance in traditional structures.

[0018] In this invention, a flip-up stop bar structure is set on the rotating shaft, and a self-locking limiting mechanism consisting of a sliding bolt, a pull rod, and a spring is set on it. After the stop bar is rotated to the limiting position, the sliding bolt can automatically enter the positioning hole set on the moving frame under the action of the spring force, thereby quickly fixing the stop bar and thus stably limiting both ends of the axle, avoiding accidental displacement of the stop bar due to vibration or tilting, and significantly improving the structural safety and reliability during transportation.

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] refer to Figures 1-5As shown, a placement rack for transporting axles includes a movable base frame 1, which is hollow inside. A movable frame 2 is symmetrically slidably mounted on top of the movable base frame 1. Multiple horizontal beams 21 are horizontally arranged on the inner side of each movable frame 2. V-shaped grooves 22 for placing axles are evenly formed on the upper surface of each beam 21. The bottom of the V-shaped grooves 22 has a "V" shape, which can improve the fit and support capacity for axles of different diameters without increasing the contact area, thereby improving stability during transport. An installation groove 23 is formed inside each beam 21, and the installation groove 23 extends horizontally through the multiple V-shaped grooves 22 to reserve adjustable space for support components. A lifting beam 3 is slidably mounted inside each beam 21, and the lifting beam 3 can move up and down within the installation groove 23. The support structure is adjustable in height; a support roller 31 is rotatably installed on the top of the lifting beam 3. The support roller 31 can reduce frictional resistance during the picking and placing of the axle by rotating, effectively improving the smoothness of the axle when pushing or pulling it out, thereby solving the problem of difficult manual operation caused by large friction in the prior art; a rotating shaft 6 is uniformly rotatably installed on one side surface of the movable base frame 1. The rotating shaft 6 passes through the lower part of multiple crossbeams 21 and is located in the lower space of the V-groove 22, and is used to drive the action of the limiting mechanism; a stop bar 61 is provided on one side of the rotating shaft 6 to limit the end of the axle. The stop bar 61 can be changed from a horizontal state to a vertical state by rotating to limit the two ends of the axle, prevent axial displacement during transportation, and improve the safety and reliability of the transportation process.

[0027] refer to Figures 1-3 As shown, rollers 11 are symmetrically mounted on both sides of the bottom of the movable base 1. The rollers 11 contact the ground and provide movement, giving the entire placement rack device good mobility. Fixed rods 13 are symmetrically arranged inside the movable base 1, along its length, serving as a slider guide structure to control the precise movement of the movable frame 2 in a straight line. A bidirectional screw 12 is rotatably mounted at the center inside the movable base 1, passing between the two fixed rods 13 and parallel to them. The section is equipped with a left-right reverse thread structure, which can drive the movable frames 2 located on both sides to move towards each other or away from each other when rotated, thereby realizing the adjustment of the distance between the movable frames 2; the bottom of the movable frame 2 is equipped with a slider 24, which is embedded in the surface of the fixed rod 13 and screwed into the bidirectional screw 12. By rotating the bidirectional screw 12, the slider 24 can be driven to slide along the fixed rod 13, so that the movable frame 2 can be adjusted laterally along the movable base frame 1 to adapt to the placement requirements of axles of different lengths, thereby solving the problem that the existing placement frame cannot be adjusted according to the axle length.

[0028] refer to Figure 3 and Figure 5As shown, a threaded rod 4 is rotatably installed on the lower inner side of the mounting slot 23. The threaded rod 4 passes through the interior of the crossbeam 21 and is arranged parallel to the bottom surface of the mounting slot 23. One end of the threaded rod 4 passes through the side of the movable frame 2 and extends to the outside, which is convenient for manual operation by the user. A knob is provided at the end of the threaded rod 4. The knob is used to drive the threaded rod 4 to rotate and transmit power to the internal components, thereby controlling the lifting and lowering action of the support mechanism to improve the convenience and accuracy of axle loading and unloading.

[0029] refer to Figure 5 As shown, the bottom of the lifting beam 3 is uniformly provided with extrusion cones 32. The extrusion cones 32 are rigidly connected to the lifting beam 3 and distributed along its length direction, and are used to achieve contact transmission with the thrust inclined block below. The moving block 5 is horizontally slidably installed inside the mounting groove 23. The moving block 5 is screwed with the threaded rod 4. Rotating the threaded rod 4 can make the moving block 5 slide along the mounting groove 23. Inclined blocks 51 are uniformly provided on the upper surface of the moving block 5. The inclined blocks 51 are in contact with the inclined surfaces of the extrusion cones 32. When the moving block 5 moves, the axial thrust can be applied to the extrusion cones 32 through the inclined blocks 51, pushing the lifting beam 3 upward, thereby driving the support roller 31 to rise out of the bottom of the V-groove 22, lifting the axle to reduce the contact resistance during loading and unloading, and solving the problem that the traditional bracket affects the operating efficiency due to excessive friction during the axle loading and unloading process.

[0030] refer to Figure 4 As shown, the surface of the movable frame 2 is evenly provided with positioning holes 25, which are vertically arranged above the rotating shaft 6 and correspond to the locking position of the stop bar 61. A sliding bolt 7 is slidably installed on the surface of the stop bar 61. The sliding bolt 7 can slide along the longitudinal direction of the stop bar 61 and be positioned inside the positioning hole 25, thereby realizing the vertical limit fixation of the stop bar 61, ensuring that the limit mechanism does not deflect due to vibration during transportation, and improving the stability and reliability of the structure.

[0031] refer to Figure 4 As shown, a pull rod 71 is provided at the end of the sliding bolt 7 away from the positioning hole 25. The pull rod 71 passes through the stop bar 61 and is connected to the sliding bolt 7. It is used to transmit external force to realize the retraction action of the sliding bolt 7. A spring 8 is sleeved on the surface of the pull rod 71. The spring 8 is located inside the stop bar 61 and is arranged around the pull rod 71. The spring 8 is used to apply a pushing force to the sliding bolt 7 in the direction of the positioning hole 25, so that the sliding bolt 7 can automatically embed into the positioning hole 25 for limit locking after the stop bar 61 is in place. This improves the self-resetting ability of the limit structure, avoids repeated manual operation, and effectively improves the efficiency and safety of transportation operation.

[0032] The working principle of this utility model is as follows: When in use, the distance between the two movable frames 2 is adjusted according to the length of the axle to ensure that both ends of the axle are limited by the stop bar 61 after the axle is placed. When adjusting, the knob at the end of the bidirectional screw 12 is rotated to control the relative movement of the two movable frames 2 through different thread surfaces, thereby achieving the purpose of adjustment. Under normal conditions, the support roller 31 moves down and retracts into the mounting groove 23 and is lower than the bottom of the V-groove 22, so that both ends of the axle are supported by the V-groove 22 to keep it fixed. Rotating the shaft 6 makes the stop bar 61 vertically upward. At this time, the spring force of the spring 8 allows the sliding bolt 7 to enter the positioning hole 25 to limit the stop bar 61 and keep it vertical, thereby limiting the end of the axle and preventing it from moving during transportation, improving the stability of transportation. Moreover, this device can use the V-groove 22 to adapt to support axles of different diameters and lengths.

[0033] When picking up or putting down the axle, especially in the inner placement position, it is necessary to push or pull the axle along the axis. At this time, the limit of the stop lever 61 on the end of the axle can be released first, and then the threaded rod 4 can be rotated to control the moving block 5 to move laterally. The pressing of the extrusion cone block 32 by the inclined block 51 causes the lifting beam 3 to move upward, which in turn causes the support roller 31 to move upward beyond the bottom of the V-groove 22, lifting the axle to reduce the friction between the axle and the inner wall of the V-groove 22 during movement. At this time, whether pushing or pulling out, the rotation of the support roller 31 can reduce the resistance and improve the convenience of loading and unloading.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
