Description

Technical Field

[0001] This utility model relates to the field of wheel hub manufacturing technology, specifically to a wheel hub transfer device. Background Technology

[0002] During the manufacturing process of wheel hubs, placement and transportation are necessary, typically achieved using wheel hub trolleys. Existing standard wheel hub trolleys have fixed placement racks, manufactured using welding, resulting in a fixed space for wheel hubs. However, wheel hub sizes are becoming increasingly diverse, ranging from 16 to 21 inches. Factories often produce wheel hubs of various sizes, making it difficult for single-sized trolleys to meet the compatibility requirements of different sizes. For example, a smaller trolley may not be able to accommodate a 21-inch wheel hub in its lower compartment, leading to wasted space and failing to maximize trolley space utilization. Even if some trolleys can accommodate larger wheels in their lower compartments, insufficient space between the upper and lower compartments can cause wheel abrasions or collisions, sometimes necessitating cross-placement.

[0003] Existing fixed-size wheel trolleys typically only accommodate and transport wheels of that specific size. If producing wheels of multiple sizes, trolleys of various sizes must be prepared, leading to resource waste. Furthermore, the lack of clear markings between different sized trolleys makes identification difficult and inconvenient to use. Additionally, fixed-size wheel trolleys are usually welded together from metal bars, making disassembly and maintenance difficult, and the direct contact between the metal and the wheel increases the risk of scratches. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a wheel hub frame vehicle that can adjust the size of the accommodating space between different layers to accommodate wheel hubs of various sizes.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is as follows:

[0006] A wheel hub frame cart includes a support frame and multiple support rods for placing wheel hubs. The support frame has multiple support slots along a vertical direction for mounting the support rods. These support slots are located at different heights on the support frame. The support rods are detachably mounted on these support slots, and each support rod has a fixing part that mates with the support slot. Because the support rods are detachably mounted on the support slots at different heights via their fixing parts, the wheel hub placement space between different layers can be adjusted by moving the support rods up and down. This allows for adjustments based on different wheel types, effectively improving the space utilization of the wheel hub frame cart and reducing inconvenience caused by fixed, unadjustable placement spaces. It offers good applicability and flexibility. Furthermore, the detachable design of the support rods facilitates maintenance and repair.

[0007] Preferably, in the aforementioned wheel hub frame vehicle, the fixing part includes a pair of opposing and spaced-apart limiting baffles, with a concave limiting groove between the pair of limiting baffles. The support slot has a fixing position for the limiting groove to engage. The concave limiting groove can engage with the fixing position on the support slot, while the limiting baffles on both sides can restrict the axial movement of the support rod, allowing the support rod to be securely fixed on the support slot, ensuring the stability of the structure. Furthermore, the way the fixing part engages with the support slot facilitates disassembly, simplifying the disassembly process. Compared to other connection methods, this connection method improves work efficiency and reduces labor intensity.

[0008] Preferably, in the aforementioned wheel hub frame vehicle, the support slot is provided with a plurality of fixing positions at equal intervals. Each fixing position includes a guide portion and a placement portion. The upper end of the guide portion is provided with an opening, and the guide portion extends obliquely from top to bottom in a direction away from the support frame. The placement portion communicates with the guide portion, and the placement portion matches the limiting slot. Specifically, multiple fixing positions on the support slot are arranged along the width of the support frame. By setting multiple fixing positions, the distance between the two support rods can be adjusted, thereby better accommodating wheel hubs of different sizes. In use, the limiting groove of the support rod is inserted into the guide part and then placed in the placement part. Since the guide part is inclined and extends from top to bottom away from the support frame, if the support rod is to be removed, force needs to be applied along the guide part towards the inner and upper side of the support frame. That is, the support rod can only be removed along the special direction of the guide part, which can effectively avoid the problem of the support rod falling off due to bumps during movement. In addition, after the wheel hub is placed on a pair of support rods, the support rod will be squeezed downward and outward under the gravity of the wheel hub. The structure of the guide part and the placement part can cooperate with it to ensure the stability of the support rod after the wheel hub is placed.

[0009] Preferably, in the aforementioned wheel hub frame vehicle, the support frame is provided in pairs, with the pair of support frames facing each other and spaced apart. The support rod is detachably disposed between the pair of support frames. Multiple support rods are mounted between the pair of support frames, wherein two support rods that are substantially at the same height level can form a set to create a placement rack for wheel hubs. The wheel hubs can be placed on the placement rack between the pair of support frames, and multiple placement racks can be formed between the support frames for wheel hubs. This structure effectively utilizes space and has good structural stability.

[0010] Preferably, in the aforementioned wheel hub frame vehicle, the fixing parts are located at both ends of the support rod, and the surface of the support rod at its middle position is provided with a rubber protective layer. The rubber protective layer on the middle surface between the fixing parts at both ends of the support rod can reduce wheel hub scratches.

[0011] Preferably, in the aforementioned wheel hub frame vehicle, the support frame includes an outer pair of outer frame columns. Each pair of outer frame columns has a set of support slots along its vertical direction. An intermediate column is also provided between the outer frame columns, and the intermediate column has two sets of support slots along its vertical direction. The set of support slots on the outer frame columns and the set of support slots on the intermediate column cooperate with each other. After support rods are placed on the support slots that are basically at the same height level, the two spaced-apart support rods can form a wheel hub placement frame. Wheel hubs can be placed on the two support rods. This structural design of an outer frame column and an intermediate column allows two sets of wheel hubs to be placed at the same height level, effectively improving the loading capacity of the frame vehicle while ensuring the overall structural stability.

[0012] Preferably, the outer frame column of the aforementioned wheel hub frame vehicle is provided with a gripping part that allows the worker to hold it and push the wheel hub frame vehicle to move, so that the worker can better control and push the wheel hub frame vehicle.

[0013] Preferably, in the aforementioned wheel hub frame cart, the two sets of support slots on the central column are positioned at a lower height than the two sets of support slots on the pair of outer frame columns. The support slots on the central column are slightly lower than those on the outer frame columns, with the height difference not being too large, ideally around 1-2 centimeters. This arrangement creates a structure where the sides are slightly higher and the middle slightly lower after the wheel hub is placed. This ensures the wheel hub is placed stably and prevents it from falling off the outside of the cart and injuring personnel in case of shaking, thus improving safety.

[0014] Preferably, in the aforementioned wheel hub frame vehicle, the support slot is provided with a locking mechanism to prevent the support rod from dislodging from the support slot. After the support rod is placed in the support slot, the locking mechanism can be used to retain the support rod within the support slot, preventing the support rod from falling out of the support slot and improving stability and safety.

[0015] Preferably, in the aforementioned wheel hub frame vehicle, each of the support slots is equipped with a marking layer. The marking layer at the support slot indicates the wheel hub size that the support slot corresponds to. That is, when the support rod is placed in the corresponding support slot, the resulting mounting bracket can hold a wheel hub of the corresponding size, allowing for quick adjustment to the desired position according to different wheel hub sizes.

[0016] Preferably, in the aforementioned wheel hub frame vehicle, the support frame is equipped with a wipeable recording board, and the top of the recording board is equipped with a shield. The recording board can be wiped and reused repeatedly. Status identification information can be recorded on the recording board, which helps to reduce the waste of disposable status recording cards. The shield on the top of the recording board serves to prevent water or other substances from falling on the recording board and affecting the clarity of the status identification information on the recording board.

[0017] Preferably, the aforementioned wheel hub frame cart further includes a bottom frame, on which multiple fixed support rods are fixedly mounted, and multiple wheels are provided below the bottom frame. Since the bottom frame serves to support the overall structure, and the bottommost storage space can be adjusted by changing the support rods of the upper layer, the bottom frame adopts a fixed connection structure. Multiple fixed rods are fixedly connected to the bottom frame to ensure the stability of the overall structure. The wheels below the bottom frame facilitate the movement of the wheel hub frame cart to transfer wheel hubs placed on it.

[0018] Compared with the prior art, the advantages of this utility model are:

[0019] This utility model's wheel hub frame cart has a simple structure and is convenient and flexible to use. It is suitable for placing and transporting wheel hubs of various sizes. Its support rods are detachably set on support slots at different heights through a fixing part. Therefore, the wheel hub placement space between different layers can be adjusted by moving the support rods up and down. During use, adjustments can be made according to different wheel types, effectively improving the space utilization rate of the wheel hub frame cart and reducing the inconvenience caused by fixed and unadjustable placement space. It has good applicability and flexibility. In addition, the support rods are set in a detachable manner, which facilitates their maintenance and repair, and has high practical application value.

[0027] To facilitate understanding of this utility model, the following description will be provided in more comprehensive and detailed manner with reference to the accompanying drawings and preferred embodiments. However, the scope of protection of this utility model is not limited to the following specific embodiments.

[0028] Example 1:

[0029] like Figure 1 and Figure 2 As shown, the wheel hub frame vehicle of this embodiment includes a support frame 1 and multiple support rods 2 for placing wheel hubs. The support frame 1 has multiple support slots 3 for placing the support rods 2 along the vertical direction. The multiple support slots 3 are arranged at different heights of the support frame 1. The multiple support rods 2 are detachably mounted on the support slots 3. The support rods 2 are provided with fixing parts 21 that cooperate with the support slots 3. Specifically, there are four sets of support slots 3 at different heights of the support frame 1. The four sets of support slots 3 are arranged at intervals from top to bottom. The support slots 3 are support ears that extend outward. The support ears have downward recessed portions that can cooperate with the fixing parts 21 of the support rods 2.

[0030] In this embodiment, the fixing part 21 includes a pair of opposing and spaced-apart limiting baffles 211, with a recessed limiting groove 212 between the pair of limiting baffles 211. The support slot 3 has a fixing position for the limiting groove 212 to be engaged. Specifically, after the support rod 2 is placed on the support slot 3, the limiting groove 212 is embedded in the support ear, and the limiting baffles 211 on both sides are engaged on the left and right sides of the support ear to fix the support rod 2 and restrict the support rod 2 from moving along its axial direction.

[0031] In this embodiment, a pair of support frames 1 are provided, which are arranged opposite each other and spaced apart. The support rod 2 is detachably disposed between the pair of support frames 1. Specifically, the support frame 1 includes a first support frame and a second support frame, and the support rod 2 is disposed between the first support frame and the second support frame. The two support rods 2 together form a placement frame for placing the wheel hub, and the wheel hub can be placed on the placement frame between the first support frame and the second support frame.

[0032] In this embodiment, the fixing part 21 is provided at both ends of the support rod 2, and a rubber protective layer 22 is provided on the surface of the middle position of the support rod 2. The body of the support rod 2 can be made of metal to improve the load-bearing capacity, and covering the middle surface of the support rod 2 body with a rubber protective layer 22 can reduce damage to the wheel hub.

[0033] In this embodiment, the support frame 1 includes an outer frame column 11, each of which has a set of support slots 3 along its vertical direction. An intermediate column 12 is also provided between the outer frame columns 11, and the intermediate column 12 has two sets of support slots 3 along its vertical direction. Specifically, the support frame 1 consists of an outer frame column 11, an intermediate column 12, and two horizontal connecting rods. The outer frame column 11 and the intermediate column 12 are parallel to each other and vertically arranged. The two horizontal connecting rods are fixed to the top and bottom ends of the outer frame column 11 and the intermediate column 12, connecting them to form a complete support frame 1. Furthermore, diagonal supports are provided between the outer frame column 11 and the intermediate column 12, which can improve the load-bearing capacity of the support frame 1.

[0034] In this embodiment, the outer frame column 11 is provided with a gripping part for easy handling by workers to move the wheel hub frame cart. Specifically, the gripping part adopts a circular tube structure to facilitate workers' control of the wheel hub frame cart.

[0035] In this embodiment, the height of the two sets of support slots 3 on the middle column 12 is basically equal to the height of the two sets of support slots 3 on the outer frame column 11.

[0036] In this embodiment, each support slot 3 is provided with a marking layer. Specifically, the marking layer is a mark engraved on the support ear. The marking layers of the support slot 3 from top to bottom are 20-21 inches for the top layer, 18-19 inches for the second layer, and 16-17 inches for the third layer. When in use, the support rod 6 can be placed in the support slot 3 of appropriate height according to the wheel hub size.

[0037] In this embodiment, the support frame 1 is provided with a wipeable recording board 4, and the top of the recording board 4 is provided with a cover plate 41. Specifically, the recording board 4 is a small whiteboard, which is set on the outside of the support frame 1. It can record status information and be reused. The cover plate 41 is specifically the part that extends outward from the top of the recording board 4.

[0038] In this embodiment, the wheel hub frame vehicle also includes a bottom frame 5, on which multiple fixed support rods 6 are fixedly installed, and multiple traveling wheels 7 are provided below the bottom frame 5. When a layer of support rods 6 is placed on the support slot 3, wheel hubs can be placed not only on the support rods 6, but also on the fixed support rods 6, thereby realizing the placement of wheel hubs in two or even more layers, improving the overall space utilization.

[0039] The cart in this embodiment can hold at least two layers of wheel hubs. The lower layer of wheel hubs is placed on a placement frame composed of multiple fixed support rods 6, and the upper layer of wheel hubs is placed on a placement frame composed of multiple support rods 6. The lower layer has four fixed support rods 6, which are paired to form two placement frames, and can hold two rows of wheel hubs. The upper layer has four detachable support rods 6, which are paired to form two placement frames, and can also hold two rows of wheel hubs.

[0040] When using the wheel hub frame cart in this embodiment, refer to the marking layer on the support slot 3, and place the support rod 6 on the corresponding support slot 3 according to the size of the wheel hub to be placed. After ensuring that the support slot 3 is placed stably, place the wheel hub to be placed vertically on the placement frame composed of two support rods 6 or on the placement frame composed of two fixed support rods 6. At this time, the round wheel hub is placed vertically between the two support rods 6, and the wheel hub can be transferred by moving the frame cart.

[0041] Example 2:

[0042] The wheel hub frame vehicle in this embodiment is basically the same as that in Embodiment 1, with the main difference being: Figure 3 and Figure 4 As shown, in this embodiment, the support slot 3 is provided with multiple fixing positions 32 at equal intervals. Each fixing position 32 includes a guide portion 321 and a placement portion 322. The upper end of the guide portion 321 has an opening, and the guide portion 321 extends obliquely from top to bottom away from the support frame 1. The placement portion 322 communicates with the guide portion 321 and matches the limiting groove 212. Specifically, each support slot 3 has three fixing positions 32 along the width direction of the wheel hub frame vehicle to facilitate adjustment of the spacing between a pair of support rods 6. The guide portion 321 of each fixing position 32 extends outward and downward.

[0043] In this embodiment, the height of the two sets of support slots 3 on the middle column 12 is lower than the height of the two sets of support slots 3 on the outer frame columns 11. Specifically, the height difference is 1 cm, that is, for the support slots 3 at the same height level, the support slots on the middle column 12 are all 1 cm lower than the support slots on the outer frame columns 11, so as to form a structure that is slightly lower in the middle and slightly higher on both sides.

[0044] Example 3:

[0045] The wheel hub frame vehicle in this embodiment is basically the same as that in embodiment 2, with the main difference being: Figure 5 As shown, in this embodiment, the support slot 3 is provided with multiple fixing positions 32 at equal intervals, and the fixing positions 32 are straight grooves for inserting the support rod 2. The support slot 3 is provided with a locking mechanism 31 to prevent the support rod 2 from falling out of the support slot 3. Specifically, the locking mechanism 31 includes an upper locking hook and a side locking hook. The upper locking hook is disposed above the multiple fixing positions 32 of the support slot 3. One end of the upper locking hook is hinged to the support slot, and the other end is provided with a hook portion that engages and locks with the side locking hook. The side locking hook is disposed on the outer side of the support slot 3. One end of the side locking hook is hinged to the support slot, and the other end is provided with a hook portion that engages and locks with the upper locking hook. When using, first forcefully separate the hook parts of the upper locking hook and the side locking hook, then rotate the upper locking hook and the side locking hook along their respective hinge points to release the fixing position 32. Then, select a suitable fixing position 32 to insert the support rod 2, and then rotate the hook parts of the upper locking hook and the side locking hook together, and forcefully engage the hook parts of the two to achieve fixation. At this time, the upper locking hook covers the fixing position 32, and even if there is shaking or bumping, the support rod 2 will not come off the support slot 3, effectively improving safety and stability.

[0046] In other embodiments, in order to prevent collisions or friction between two rows of wheel hubs located at the same height level, a partition can be installed between the two intermediate columns 12. The partition is specifically a rubber partition, which can separate the two rows of wheel hubs on the same level and prevent collisions or scratches between the wheel hubs when there is a large amount of shaking.

[0047] In other embodiments, the wheel hub frame vehicle can be equipped with more support slots at different height levels according to actual conditions, or multiple support rods 6 can be installed at different height levels to form two or more layers of placement racks to accommodate more wheel hubs.

[0048] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
