[0028] The utility model provides a device for simultaneously equipping two tires of different or same specifications for a working machine such as a crane. For different tire models, large and small tires can be equipped at the same time. Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The specific implementation of the spare tire bracket of the present utility model is described.

[0029] The utility model provides a spare tire bracket, comprising a first bracket and a second bracket. The first bracket comprises a first base portion 10 mounted on the rear of an operating machine, and a first assembly plate 11 located at an end of the first base portion 10 away from the operating machine, the first assembly plate 11 being provided with a first assembly hole group adapted for a first spare tire 31 of the operating machine. The second bracket comprises a second base portion 20, one end of the second base portion 20 being provided with a second base plate 21, the second base plate 21 being provided with mounting holes adapted for the first assembly hole group, the other end of the second base portion 20 being provided with a second assembly plate 22, the second assembly plate 22 being provided with a second assembly hole group adapted for a second spare tire 32 of the operating machine. The first spare tire 31 and the second base plate 21 are mounted on the first assembly plate 11 by fasteners, and the second base plate 21 is located on the outside of the first spare tire 31, and the second spare tire 32 is mounted on the second assembly plate 22 by fasteners.

[0030] The first base portion 10 of the first bracket is responsible for securing the entire spare tire bracket to the work machine through welding or other fixing methods. A first mounting plate 11 is provided at the end of the first base portion 10 facing away from the work machine. This first mounting plate 11 has a set of first mounting holes for mounting a first spare tire 31 suitable for the work machine. A second base portion 20 of the second bracket is provided at one end with a second base plate 21. This second base plate 21 has mounting holes that match the first mounting hole set on the first mounting plate 11, allowing the second bracket to be secured to the first mounting plate 11. A second mounting plate 22 is provided at the other end of the second base portion 20. This second mounting plate 22 has a set of second mounting holes for mounting a second spare tire 32 suitable for the work machine. The first spare tire 31 is mounted to the first mounting plate 11 via fasteners, while the second base plate 21 is secured to the first mounting plate 11 via fasteners and is positioned outside the first spare tire 31. The second spare tire 32 is also mounted to the second mounting plate 22 via fasteners, enabling simultaneous mounting of two spare tires.

[0031] The spare tire bracket of the present invention can not only support the simultaneous installation of multiple spare tires, but also can preferably adjust the design of the second assembly plate 22 according to spare tires of different sizes and specifications, thereby achieving flexible configuration of spare tires of different sizes, improving the versatility and adaptability of the spare tire bracket, solving the problem of the singleness of traditional spare tire mounting racks, and improving the convenience and economy of engineering machinery in spare tire replacement and maintenance.

[0032] Preferably, in the spare tire bracket provided by the present invention, the first base portion 10 and the second base portion 20 in the above-described embodiment are both triangular prism structures. Compared to other shapes, the triangular prism structure provides better mechanical stability, especially when subjected to lateral forces, effectively dispersing stress and increasing the stability of the entire spare tire bracket. It is understood that, depending on actual use requirements, the first base portion 10 and the second base portion 20 may also be configured as other polygonal prism structures or cylindrical structures.

[0033] According to the utility model, a spare tire bracket is provided with a first base portion 10, and three support plates 12 extend along the ridges of the triangular prism structure of the first base portion 10. When the first spare tire 31 is mounted on the first assembly plate 11, at least a portion of the inner edge of the first spare tire 31 is supported on the support plates 12. The first base portion 10 adopts a triangular prism structure, which provides good stability and strength. Support plates 12 are provided on each ridge of the triangular prism structure, extending along the ridge direction, forming a stable support frame around the periphery of the triangular prism structure. The main function of the support plates 12 is to provide additional support points when the first spare tire 31 is mounted on the first assembly plate 11, ensuring that the spare tire is evenly stressed when installed and preventing displacement or shaking during transportation. By placing a portion of the inner edge of the spare tire on the support plates 12, the weight of the spare tire is distributed, reducing the local pressure between the spare tire and the assembly plate, and thus improving the stability of the spare tire's fixation.

[0034] Furthermore, according to a spare tire bracket provided by the present invention, a first base plate 13 is provided at one end of the first base portion 10 facing the operating machine; the first base plate 13 is fixed to the tail of the operating machine; and the support plate 12 is welded and fixed to the first base plate 13 at one end facing the first base plate 13. The first base plate 13 is connected to the tail of the operating machine by welding or other fixing methods to ensure that the spare tire bracket is firmly installed. By fixing the first base plate 13 to the tail of the operating machine and welding the support plate 12 to the first base plate 13, an additional supporting connection is provided between the first base portion 10 and the first base plate 13 by the support plate 12. The welding and fixing method of the support plate 12 and the first base plate 13 enhances the structural strength of the entire spare tire bracket, which can ensure the stability of the entire spare tire bracket on the operating machine. The width of one end of the support plate 12 close to the first base plate 13 is preferably greater than the width of the rest of the support plate 12, thereby increasing the welding area between the support plate 12 and the first base plate 13 and improving the welding strength on the one hand, and forming a stepped edge structure at the outer edge of the support plate 12 on the other hand, which can provide a limiting effect on the inner side of the first spare tire 31.

[0035] On the other hand, according to a spare tire bracket provided by the present invention, an extension bracket 23 perpendicular to the second assembly plate 22 is preferably provided on the side of the second assembly plate 22 facing away from the second base portion 20. When the second spare tire 32 is mounted on the second assembly plate 22, at least a portion of the inner edge of the second spare tire 32 is supported on the extension bracket 23. The extension bracket 23 is designed to provide an additional support point to ensure that the second spare tire 32 can be stably fixed on the second assembly plate 22 after installation. When the second spare tire 32 is mounted on the second assembly plate 22, at least a portion of the inner edge of the second spare tire 32 will be supported on the extension bracket 23, so that the second spare tire 32 is not only fixed by the second assembly plate 22, but also receives additional support from the extension bracket 23 on its inner edge, thereby enhancing the fixing effect.

[0036] Furthermore, in the spare tire bracket provided by the present invention, the distal end of the extension bracket 23 is preferably provided with an upward-facing hook-shaped structure. This hook-shaped structure primarily serves to provide a position-limiting function on the outside of the second spare tire 32. This hook-shaped structure effectively prevents the second spare tire 32 from lateral or longitudinal displacement due to vibration or inertia during driving, thereby improving the stability of the spare tire when installed.

[0037] According to a spare tire bracket provided by the utility model, the fastener includes a long bolt 41 and a nut 42 adapted to the long bolt 41. Specifically, regarding the installation of the first spare tire 31, the long bolt 41 is used to pass through the first assembly plate 11, the wheel hub of the first spare tire 31, and the second base plate 21 in sequence. After passing through these three components, the long bolt 41 cooperates with the long bolt 41 on the other side of the second base plate 21 through the nut 42 to achieve the fixation of the first spare tire 31, the first assembly plate 11, and the second base plate 21. Regarding the installation of the second spare tire 32, the long bolt 41 is used to pass through the second assembly plate 22 and the wheel hub of the second spare tire 32. After passing through these two components, the long bolt 41 cooperates with the long bolt 41 on the other side of the second assembly plate 22 to achieve the fixation of the second spare tire 32. Through the cooperation of the long bolt 41 and the nut 42, the first spare tire 31 and the second spare tire 32 can be firmly fixed to their respective assembly plates. It is understandable that the fasteners may also adopt other structural forms, such as snap-on fixing components or other types of threaded parts that are more convenient to install and disassemble.

[0038] Furthermore, according to a spare tire bracket provided by the utility model, the fastener includes a washer 43 adapted to the long bolt 41. The use of the washer 43 further optimizes the fastening effect, reduces the wear between the spare tire and the assembly plate, and extends the service life of the spare tire and the bracket. Specifically, the washer 43 can be used to increase the contact area between the fastener and the spare tire or the assembly plate, thereby reducing the pressure per unit area. The washer 43 can be of various types such as ordinary flat washers 43 and flat anti-loosening washers 43. The spare tire bracket of the utility model can select a suitable washer 43 according to different usage requirements. When using the long bolt 41 to fix the spare tire, a washer 43 can be added between the bolt and the nut 42. The washer 43 can be placed between the bolt head and the spare tire or the assembly plate, or between the nut 42 and the second base plate 21 or the second assembly plate 22.

[0039] According to a spare tire bracket provided by the utility model, the second spare tire 32 has a variety of sizes and specifications; wherein, the spare tire bracket is provided with a variety of different types of second brackets; the second base plates 21 of the various second brackets are the same, and the second assembly plates 22 of the various second brackets respectively have a second assembly hole group adapted to the second spare tires 32 of different sizes and specifications. By designing a variety of second brackets, the spare tire bracket can adapt to the second spare tires 32 of different sizes and specifications, thereby improving the versatility and flexibility of the spare tire bracket. Users can choose the appropriate type of second bracket according to actual needs without having to replace the entire spare tire bracket. The second base plates 21 of the various second brackets are the same, which means that all types of second brackets can be matched with the first assembly plate 11 of the first bracket, ensuring interchangeability. The second assembly plates 22 of different types of second brackets have different assembly hole groups, which can adapt to spare tires of different sizes, thereby improving the adaptability of the spare tire bracket to different vehicle models and spare tire sizes.

[0040] The utility model also provides a working machine provided with the spare tire bracket of any one of the above embodiments.

[0041] In the embodiments of the present invention, the type of working machine is not limited, for example, the working machine may be an excavator, a crane, a loader, etc. In other words, as long as the working machine can use the spare tire bracket of the present invention, it will be fine.

[0042] Preferably, the first bracket is welded to the tail of the crane, the large spare tire is installed on the first bracket, then the second bracket is installed close to the large spare tire, and finally the small spare tire is installed on the second bracket, so that two sizes of spare tires can be installed at the tail of the crane through one spare tire bracket.
