Abstract
Description
Technical Field
[0001] This utility model relates to the field of tire technology, and in particular to anti-skid solid tires for aerial work vehicles. Background Technology
[0002] As key equipment in fields such as power maintenance, construction, and municipal engineering, aerial work platforms often face complex road conditions, such as slippery roads in rainy or snowy weather, gravel and slag roads at construction sites, and high and low temperature environments for outdoor operations. This places extremely high demands on the anti-skid performance, structural stability, and durability of the tires.
[0003] Existing aerial work platform tires mostly rely on unidirectional tread patterns for anti-skid design. When driving or working on wet or slippery surfaces, a single tread pattern is difficult to quickly expel water between the tire tread and the ground, easily forming a water film that causes "hydroplaning" and significantly reduces tire grip. To improve anti-skid performance, some users will install additional auxiliary devices such as snow chains. However, existing snow chains have poor compatibility with aerial work platform tires and cannot accurately fit the tire tread pattern. After installation, they are prone to loosening and shifting, causing abnormal noise during driving due to friction with the tire tread, and even causing accelerated wear of the tire tread pattern. Therefore, this application proposes an anti-skid solid tire for aerial work platforms. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a non-skid solid tire for aerial work vehicles to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-skid solid tire for aerial work platforms, comprising: The wheel hub is made of aluminum alloy, and the center disc is connected to the inner side of the wheel hub by multiple circularly arrayed spokes; The tire body is fitted onto the outside of the wheel hub. The surface of the tire body has two sets of left and right distributed anti-slip patterns. The anti-slip patterns are L-shaped and the vertical part of the anti-slip patterns is inclined. The number of anti-slip patterns in the two sets is the same, and the horizontal and vertical parts of the two sets of anti-slip patterns are distributed in an interlaced manner on the surface of the tire body. The tire body and the anti-slip patterns on its surface are integrated and made by vulcanization process. Anti-skid components are fitted onto the outside of the tire body and connected to the wheel hub; A locking assembly is installed between the wheel hubs to lock the anti-slip assembly.
[0006] Optionally, two sets of positioning rods are installed on both sides of the inner side of the wheel hub. The number of positioning rods in each set is the same as the number of anti-slip patterns in each set. Each set of positioning rods is installed in a circular array on the inner side of the wheel hub. The anti-slip component is connected to the positioning rods on the inner side of the wheel hub, and the locking component is installed between the two sets of positioning rods on the inner side of the wheel hub.
[0007] Optionally, the anti-skid assembly includes anti-slip block components and anti-skid chain components. The anti-slip block components are fitted onto the surface of the tire carcass and embedded between the anti-skid patterns on its surface. The number of anti-skid chain components is the same as the number of each set of anti-skid patterns. Multiple sets of anti-skid chain components are arranged in a circular array and longitudinally connected between the anti-slip block components. The two ends of each set of anti-skid chain components are respectively connected to the positioning rod corresponding to the position inside the wheel hub.
[0008] Optionally, the anti-slip block component includes inserts, first steel cables, and insert rods. The number of inserts is the same as the number of anti-slip chain components, and each insert is fitted into the gap between adjacent anti-slip treads. Two first steel cables are provided, which are inserted through and connected between multiple inserts. A connecting rod is installed between the same end of each of the two first steel cables. The ends of the two connecting rods are provided with insertion holes. The insert rod is U-shaped and is inserted through and connected into the insertion holes inside the two connecting rods. Both ends of the insert rod are threaded with locking nuts. Three anti-slip teeth are provided at equal intervals on the outer side of each insert. The material and process of the inserts are the same as those of the tire body.
[0009] Optionally, the anti-skid chain component includes a second steel cable, anti-skid chains, a third steel cable, and hanging rings. The second steel cable is longitudinally inserted into the corresponding insert. Two anti-skid chains are provided and connected to both ends of the second steel cable respectively. The two anti-skid chains are located on both sides of the corresponding insert. Two third steel cables are provided and connected to the ends of the two anti-skid chains away from the second steel cable respectively. Two hanging rings are provided and connected to the ends of the two third steel cables away from the anti-skid chains respectively. The two hanging rings are respectively fitted onto the positioning rods corresponding to the inner side of the wheel hub.
[0010] Optionally, the locking assembly includes rings and bolts. Two rings are provided. The outer wall of the rings has a circular array of slots that are the same number and position as the positioning rods. The opening of each slot extends to the inner side of the ring. The two rings can be respectively mated to two sets of positioning rods on the inner wall of the wheel hub. The inner wall of each ring has four fixing blocks installed in a circular array. Four bolts are provided, and the four bolts are respectively inserted through and inserted between the fixing blocks at corresponding positions on the inner wall of the two rings.
[0011] The beneficial effects of this utility model are: The tire surface features an L-shaped inclined vertical section combined with interlaced horizontal sections to create an anti-skid tread structure. Compared to existing single-direction tread patterns, the interlaced horizontal sections form multi-directional drainage channels between the tire tread and the ground, quickly draining water accumulated in rainy or snowy weather, significantly reducing hydroplaning and improving grip on wet surfaces. The anti-skid components are precisely matched with the tire tread pattern: the anti-skid block inserts fit into the gaps between the horizontal sections of the anti-skid tread, preventing the inserts from shifting and further increasing the tread roughness through the anti-skid teeth on the outside of the inserts, thus strengthening the grip on the ground. The anti-skid chain components are longitudinally connected to the anti-skid block, forming a three-dimensional anti-skid structure of "lateral inserts + longitudinal chain," solving the problems of poor compatibility and easy loosening of traditional anti-skid chains with tires.
[0012] The anti-skid assembly is precisely connected to the wheel hub via a positioning rod: the hanging ring of the anti-skid chain component is fitted onto the positioning rod inside the wheel hub, thus fixing the anti-skid assembly to the wheel hub; the two rings of the locking assembly are connected to the positioning rod through grooves and locked by bolts through the fixing block, forming a double fixing structure of "positioning rod positioning + ring locking", which completely solves the problem of traditional anti-skid chains being easy to loosen after installation.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0015] Please see Figures 1-6 This utility model provides a technical solution: a solid anti-skid tire for aerial work platforms, including a hub 1 made of aluminum alloy. The hub 1 has a central disc connected to its inner side by multiple circularly arrayed spokes. A tire body 2 is fitted onto the outer side of the hub 1. The surface of the tire body 2 has two sets of left-right distributed anti-skid patterns. The anti-skid patterns are L-shaped, with the vertical portions inclined. The two sets of anti-skid patterns have the same number of patterns, and the horizontal portions are staggered on the surface of the tire body 2. The tire body 2 and its surface anti-skid patterns are integrated and vulcanized. The tire body 2 is constructed by fitting anti-skid component 3 onto the outside of the tire body 2 and connecting it to the wheel hub 1. Locking component 4 is set between the wheel hubs 1 and locks the anti-skid component 3. The tire body 2 achieves an integrated design with the L-shaped anti-skid pattern through a vulcanization process. The two sets of anti-skid patterns are distributed in an alternating manner, which can not only enhance the structural stability and durability of the tire body 2, but also quickly drain accumulated water and reduce hydroplaning through the multi-directional pattern. At the same time, together with the anti-skid component 3 and the locking component 4, a basic anti-skid and fixing system is formed to meet the core requirements of tire anti-skid and stability for aerial work vehicles operating on complex road surfaces.
[0016] like Figure 1 and Figure 5 As shown, two sets of positioning rods 11 are installed on both sides of the inner side of the wheel hub 1. The number of positioning rods 11 in each set is the same as the number of anti-slip patterns in each set. Each set of positioning rods 11 is installed in a circular array on the inner side of the wheel hub 1. The anti-slip component 3 is connected to the positioning rods 11 on the inner side of the wheel hub 1. The locking component 4 is installed between the two sets of positioning rods 11 on the inner side of the wheel hub 1. By setting a circular array of positioning rods 11 on both sides of the inner side of the wheel hub 1 to match the number of anti-slip patterns, a precise connection point is provided for the anti-slip component 3, ensuring that the installation position of the anti-slip component 3 is compatible with the anti-slip pattern of the tire body 2 and avoiding displacement. At the same time, the locking component 4 is installed between the two sets of positioning rods 11, laying the structural foundation for locking the anti-slip component 3, further improving the stability of the connection between the anti-slip component 3 and the wheel hub 1, and solving the problem of poor adaptability of traditional anti-slip auxiliary devices.
[0017] like Figure 1 , Figure 2 and Figure 3As shown, the anti-skid component 3 includes anti-slip block components 31 and anti-skid chain components 32. The anti-slip block components 31 are fitted onto the surface of the tire body 2 and embedded between the anti-skid patterns on its surface. The number of anti-skid chain components 32 is the same as the number of each set of anti-skid patterns, and multiple sets of anti-skid chain components 32 are arranged in a circular array and longitudinally connected between the anti-slip block components 31. The two ends of each set of anti-skid chain components 32 are respectively connected to the positioning rods 11 corresponding to the inner side of the wheel hub 1. The anti-slip block components 31 are embedded in the gaps of the anti-skid patterns of the tire body 2, which can fit tightly against the tire surface and prevent loosening, while increasing the roughness of the tire surface to enhance grip. The anti-skid chain components 32 are arranged in a circular array and longitudinally connected to the anti-slip block components 31, and the two ends are connected to the positioning rods 11 on the inner side of the wheel hub 1 to form a three-dimensional anti-skid structure, which greatly improves the anti-skid performance of the tire on complex road surfaces such as gravel and wet surfaces.
[0018] like Figure 2 and Figure 3 As shown, the anti-slip block component 31 includes inserts 311, first steel cables 312, and insert rods 315. The number of inserts 311 is the same as the number of anti-slip chain components 32, and each insert 311 is fitted into the gap between adjacent anti-slip treads. Two first steel cables 312 are provided, and the two first steel cables 312 are inserted through and connected between multiple inserts 311. A connecting rod 314 is installed between the same end of each of the two first steel cables 312. The ends of the two connecting rods 314 are provided with insertion holes. The insert rod 315 is U-shaped and is inserted through and connected into the insertion holes inside the two connecting rods 314. Both ends of the insert rod 315 are threaded with locking nuts. Each insert 311... Three anti-skid teeth 313 are evenly spaced on the outer side of the tire. The material and process of the insert 311 are the same as those of the tire carcass 2. The number of inserts 311 matches the anti-skid chain component 32 and is fitted into the gap of the anti-skid pattern to ensure precise fit with the tire tread. The outer anti-skid teeth 313 further enhance the ground grip. Two first steel cables 312 pass through multiple inserts 311 to connect them into one piece. With the help of the connecting rod 314, U-shaped insert 315 and locking nut, the anti-skid block component 31 can be quickly assembled and securely connected. The inserts 311 use the same material and process as the tire carcass 2 to ensure that their performance is consistent with the tire carcass 2, avoid uneven wear caused by material differences, and extend the overall service life of the tire.
[0019] like Figure 3 and Figure 4As shown, the anti-skid chain component 32 includes a second steel cable 321, anti-skid chains 322, a third steel cable 323, and hanging rings 324. The second steel cable 321 is longitudinally inserted into the corresponding insert 311. Two anti-skid chains 322 are provided and are respectively connected to the two ends of the second steel cable 321. The two anti-skid chains 322 are respectively located on both sides of the corresponding insert 311. Two third steel cables 323 are provided and are respectively connected to the ends of the two anti-skid chains 322 away from the second steel cable 321. Two hanging rings 324 are provided and are respectively connected to the ends of the two third steel cables 323 away from the anti-skid chains 322. 4 are respectively fitted onto the positioning rods 11 at the inner side of the wheel hub 1. The second steel cable 321 is longitudinally inserted into the insert 311 to achieve a stable connection with the anti-slip block component 31. Two anti-slip chains 322 are located on both sides of the insert 311 to enhance the longitudinal anti-slip effect. The combination of the third steel cable 323 and the hanging ring 324 provides a convenient and firm connection between the anti-slip chain component 32 and the positioning rod 11. The design of the hanging ring 324 fitted onto the positioning rod 11 facilitates installation and disassembly, while ensuring that the anti-slip chain component 32 does not loosen or shift during driving and operation, further improving the practicality and stability of the anti-slip component 3.
[0020] like Figure 6 As shown, the locking component 4 includes rings 41 and bolts 44. There are two rings 41. The outer wall of the rings 41 has a circular array of slots 42, which are the same number and position as the positioning rods 11. The opening of each slot 42 extends to the inner side of the ring 41. The two rings 41 can be connected to the two sets of positioning rods 11 on the inner wall of the wheel hub 1, respectively. The inner wall of each ring 41 has four fixing blocks 43 installed in a circular array. There are four bolts 44. The four bolts 44 are inserted through and inserted between the fixing blocks 43 on the inner wall of the two rings 41. The two rings 41 are connected to the positioning rods 11 through the slots 42 that match the number and position of the positioning rods 11, so as to achieve the initial positioning of the rings 41. Then, the four bolts 44 are used to lock the two rings 41 through the fixing blocks 43, forming a double fixing structure. This completely solves the problem of easy loosening after the traditional anti-skid structure is installed, and ensures that the anti-skid component 3 remains stable during the driving and operation of the aerial work vehicle, thus improving the safety of tire use.

Those skilled in the art should consider the specification as a whole.
