Description

Technical Field

[0001] This utility model relates to the field of forklift wheel rim technology, and in particular to a solid tire wheel rim for forklifts. Background Technology

[0002] Forklift solid tire rims are core metal structural components that fit solid forklift tires and connect the tires to the forklift axles. They primarily function to fix the solid tire's position and transmit power and load to the axles. Their design must match the specifications of the solid forklift tire (such as tread width and inner diameter). They are typically made of high-strength steel through forging or stamping processes, possessing wear-resistant and impact-resistant properties to meet the operational needs of forklifts in warehousing and logistics scenarios, including frequent starts and stops, carrying heavy loads (often several tons to tens of tons), and handling complex terrain (such as concrete floors and slightly bumpy surfaces). Structurally, they generally include the rim body, retaining ring, and other components. Some models optimize the rim's strength distribution and mounting interface according to the different functional requirements of the forklift's drive wheels or steering wheels, ensuring a tight fit between the solid tire and the rim to prevent tire misalignment or detachment during operation. They also help maintain the stability of the forklift's driving and steering, making them a crucial basic component for ensuring the safe and efficient operation of forklifts.

[0003] Traditional solid tire rims for forklifts, due to their one-piece design and lack of quick-access shielding for bolted connections, present significant shortcomings and safety hazards. The one-piece design means that if any part of the rim is damaged, the damaged component cannot be replaced individually; the entire rim must be disassembled and replaced. This significantly increases spare parts and repair costs, prolongs downtime, and impacts forklift operating efficiency. Furthermore, the inconvenience of quick shielding for bolted connections means that the bolts, constantly exposed, are susceptible to corrosion from dust, oil, and moisture in the forklift's operating environment. This can lead to bolt jamming and difficulty in loosening during subsequent disassembly and repair, further complicating maintenance. The lack of shielding also makes the bolts prone to loosening during operational vibrations, potentially even causing rim components to detach, threatening forklift safety and making them unsuitable for the high-frequency, high-load operation demands of forklifts. Utility Model Content

[0004] The purpose of this utility model is to provide a solid tire rim for forklifts that solves the problems of traditional solid tire rims for forklifts, which have obvious shortcomings and safety hazards due to their one-piece design and lack of quick-covering structure for bolt connections. The one-piece design means that if any part of the rim is damaged, the damaged part cannot be replaced individually; the entire rim must be disassembled and replaced. This not only significantly increases spare parts and maintenance costs but also prolongs downtime, affecting the normal operating efficiency of the forklift. Furthermore, it is not convenient to quickly cover the bolt connections. On the one hand, the bolts are exposed for a long time and are susceptible to corrosion from dust, oil, and moisture in the forklift's operating environment. This can lead to bolt jamming and difficulty in loosening during subsequent disassembly and maintenance, further increasing the difficulty of repair. On the other hand, the lack of protection makes the bolts prone to loosening during operational vibrations, and there is even a risk of rim components falling off, threatening the safety of forklift operation and making it difficult to meet the high-frequency, high-load usage requirements of forklifts.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a solid tire rim for forklifts, comprising a first hub and a second hub, and further comprising: A baffle is provided on one side of the first wheel hub and the second wheel hub; A drive component is disposed on one side of the first wheel hub and the second wheel hub; A fixing element is disposed on the inner side of the first wheel hub and the second wheel hub; The first and second wheel hubs are modularly designed, allowing for easy disassembly and installation of the first and second wheel hubs. The connection between the first and second wheel hubs can be shielded by the drive component and the baffle.

[0006] In a preferred embodiment, the pad is fixedly disposed on the inner side of the first wheel hub and the second wheel hub; The first connecting ring is rotatably mounted on one side of the pad; The connecting arm is rotatably mounted on one side of the first connecting ring; The second connecting ring is fixedly disposed on one side of the pad block; An arc-shaped groove is formed on one side of the first connecting ring.

[0007] In a preferred embodiment, a limiting head is fixedly provided in a ring on one side of the pad, and the limiting head is disposed inside the arc-shaped groove.

[0008] In a preferred embodiment, a snap-fit ​​groove is provided on the inner side of one end of the first hub and the second hub, and a protrusion is provided on the outer side of the end of the first connecting ring, with the protrusion of the first connecting ring located inside the snap-fit ​​groove.

[0009] In a preferred embodiment, a second connecting hole is provided on the protrusion on the outer side of the end of the first connecting ring to assist in rotating the first connecting ring.

[0010] In a preferred embodiment, a protective plate is fixedly provided on the inner side of one end of the first wheel hub and the second wheel hub, and the protective plate is used to cover the first wheel hub and the second wheel hub.

[0011] In a preferred embodiment, the first connecting hole is formed on the inner side of the pad; The second connecting hole is located on the inner side of the end of the protective plate.

[0012] In a preferred embodiment, the first hub and the second hub are connected by a through hole on one side, and a circular baffle can block the first connection hole and the second connection hole.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention, in use, utilizes a modular design and a convenient disassembly and protective structure for solid tire rims on forklifts, balancing maintenance convenience with operational safety. During use, the first and second wheel hubs are fitted together and connected by bolts passing through the first and second connecting holes. This modular design allows for easy replacement of either the first or second wheel hub if one side is damaged, eliminating the need for complete replacement; only the bolts on the corresponding side need to be removed, significantly reducing maintenance costs and replacement time. During disassembly, rotating the first connecting ring via the snap-fit ​​groove triggers a connecting arm that pulls a rotating baffle, removing the obstruction to the first and second connecting holes and facilitating easy disassembly of the first and second wheel hubs. The baffle's obstruction effectively prevents unnecessary accidental disassembly, avoiding safety hazards caused by loose rim components during forklift operation. This design simplifies daily maintenance processes, improves the economy of rim use, and ensures forklift stability during operation through its protective structure, making it suitable for high-frequency, high-load forklift usage scenarios.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1: Please see Figure 1 - Figure 4 This embodiment provides a solid tire rim for forklifts that facilitates the covering of the connection point. The specific idea is as follows: A solid tire rim for forklifts includes a first hub 1 and a second hub 101. The solid tire rim for forklifts also includes a baffle 2 and a drive component.

[0018] The baffle 2 for shielding is provided on one side of the first hub 1 and the second hub 101; The driving component for driving the baffle 2 to rotate is located on one side of the first hub 1 and the second hub 101. The device allows for easy disassembly and installation of the first hub 1 and the second hub 101, and the connection between the first hub 1 and the second hub 101 can be blocked by the drive component and the baffle 2.

[0019] As examples, in this embodiment, the driver includes: The pad 201 used for connection is fixedly connected to the inner side of the first hub 1 and the second hub 101; The first connecting ring 202 used for connection is rotatably connected to one side of the pad block 201; The connecting arm 203, which is used for support, is rotatably connected to one side of the first connecting ring 202; The second connecting ring 204, which serves as a connector, is fixedly connected to one side of the pad block 201; Among them, the arc-shaped groove 205, which plays a limiting role, is formed on one side of the first connecting ring 202.

[0020] In addition, a limiting head 207 is fixedly connected to one side of the pad 201 in a ring shape. The limiting head 207 is located inside the arc groove 205 and is used to limit the first connecting ring 202.

[0021] It should be noted that a snap-fit ​​groove 208 is provided on the inner side of one end of the first hub 1 and the second hub 101, and a protrusion is provided on the outer side of the end of the first connecting ring 202. The protrusion of the first connecting ring 202 is located on the inner side of the snap-fit ​​groove 208.

[0022] In addition, a second connecting hole 210 is provided on the protrusion on the outer side of the end of the first connecting ring 202 to assist in rotating the first connecting ring 202. The first connecting ring 202 can be rotated by means of the snap-fit ​​groove 208.

[0023] Among them, a protective plate 209 is fixedly connected to the inner side of one end of the first wheel hub 1 and the second wheel hub 101. The protective plate 209 is used to cover the first wheel hub 1 and the second wheel hub 101.

[0024] It should be noted that by rotating the first connecting ring 202, the connecting arm 203 can be driven to rotate. When the connecting arm 203 rotates, it will push one end of the baffle 2 to rotate, thereby driving multiple baffles 2 to rotate at the same time.

[0025] Example 2: Please see Figure 1 - Figure 4 This embodiment provides a solid tire rim for forklifts that is easy to maintain, and the specific idea is as follows: A solid tire rim for forklifts includes a first hub 1 and a second hub 101, and the solid tire rim for forklifts also includes a fixing member.

[0026] The fastener for connecting the first hub 1 and the second hub 101 is located on the inner side of the first hub 1 and the second hub 101. As examples, in this embodiment, the fastener includes a first connecting hole 206 and a protective plate 209.

[0027] The first connecting hole 206, which serves as a connection, is located on the inner side of the pad 201; The second connecting hole 210, which serves as a connection, is located on the inner side of the end of the guard plate 209.

[0028] It should be noted that the first hub 1 and the second hub 101 are connected by a through hole on one side, and the circular baffle 2 can block the first connecting hole 206 and the second connecting hole 210.

[0029] Working principle: When using this device, the user can attach the first hub 1 and the second hub 101 together and connect them by bolts through the first connecting hole 206 and the second connecting hole 210. At this time, the two first hubs 1 and the second hub 101 are modularly designed. When one side of the second hub 101 or the first hub 1 is damaged, it can be replaced by simply removing the bolts on that side. When the user needs to disassemble the first hub 1 or the second hub 101, the user can rotate the first connecting ring 202 inside the snap-fit ​​groove 208. When the first connecting ring 202 rotates, it will pull the baffle 2 on one side of the second connecting ring 204 through the connecting arm 203 to rotate, rotating the baffle 2 from the side of the first connecting hole 206 and the second connecting hole 210, so that it removes the obstruction of the first connecting hole 206 and the second connecting hole 210, and the first hub 1 and the second hub 101 can be easily disassembled. The obstruction state of the baffle 2 can prevent the accidental disassembly of the first hub 1 and the second hub 101.

[0030] The solid tire rims of this forklift feature a modular design and a convenient disassembly and protective structure, balancing ease of maintenance with operational safety. During use, the first hub 1 and the second hub 101 are fitted together and connected by bolts passing through the first connecting hole 206 and the second connecting hole 210. This modular design allows for easy replacement of either the second hub 101 or the first hub 1 if one side is damaged; only the bolts on the corresponding side need to be removed, significantly reducing maintenance costs and replacement time. During disassembly, rotating the first connecting ring 202 via the snap-fit ​​groove 208 triggers the connecting arm 203, which in turn rotates the baffle 2, removing the obstruction to the first connecting hole 206 and the second connecting hole 210. This facilitates easy disassembly of the first hub 1 and the second hub 101, while the baffle 2's obstructing state effectively prevents unnecessary accidental disassembly, avoiding safety hazards caused by loose rim components during forklift operation. This design simplifies daily maintenance procedures, improves the economy of rim use, and ensures the stability of forklift operation through a protective structure, making it suitable for high-frequency, high-load use scenarios of forklifts.
