[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The present invention is further described in detail below in conjunction with the embodiments.

[0021] A specific embodiment of a safe and durable mining wheel assembly provided by the utility model:

[0022] like Figure 1 and Figure 2 As shown, a safe and durable mining wheel assembly includes a rim 1, a tire 2 and a spoke 3. The outer ring of the side of the rim 1 is provided with a locking ring groove, and the locking ring groove is used to install a locking ring 5. Figure 2-5 As shown, a reinforcing ring 6 is fixed to the inner ring of the side of the rim 1. Preferably, the reinforcing ring 6 is fixed to the inner ring of the side of the rim 1 by welding. The reinforcing ring 6 corresponds to the position of the locking ring groove. The reinforcing ring 6 can have a reinforcing support effect on the locking ring groove of the rim 1. An annular side guard plate 7 is provided on the reinforcing ring 6. The annular side guard plate 7 is located on the outer side of the tire 2. The annular side guard plate 7 is installed on the reinforcing ring 6 by a number of bolts 8. When the wheel assembly reaches the end of its service life, the annular side guard plate 7 can be removed for reuse; the outer diameter of the annular side guard plate 7 needs to be smaller than the outer diameter of the tire 2 to ensure the annular The side guard plate 7 does not contact the road surface, which affects the rolling of the tire 2; in addition, there is a gap between the annular side guard plate 7 and the tire 2, which provides sufficient deformation space for the tire 2 under load; the annular side guard plate 7 is preferably a metal steel plate, which is durable and can protect the rubber tire 2 from external scratches, punctures and collisions, avoid early damage to the tire 2, and extend the service life of the tire 2; in addition, even when working in a harsh operating environment, the rim 1 is deformed and the lock ring 5 falls off, the outer annular side guard plate 7 can prevent the lock ring 5 from bursting outward under high pressure, thereby avoiding safety accidents that cause injury to people.

[0023] As another embodiment of the utility model, this embodiment also optimizes the installation of the annular side guard plate 7. Specifically, a plurality of connecting blocks 9 are fixed to the side of the annular side guard plate 7, and all the connecting blocks 9 are arranged in an annular array around the center of the annular side guard plate 7, and each connecting block 9 is fixed to the reinforcement ring 6 by a bolt 8; and when the connecting block 9 is fixed to the reinforcement ring 6 by a countersunk bolt, the connecting block 9 is close to the inner ring of the side of the rim 1, which can facilitate the positioning and installation of the annular side guard plate 7 on the one hand, and can also support the inner ring of the rim 1 on the other hand. When the annular side guard plate 7 is subjected to a collision impact, the connecting block 9 can disperse and transmit the impact force to the entire rim 1, and the installation bolts 8 are not subject to shear force, are not easy to deform, do not affect disassembly, can be reused, and reduce the cost of use.

[0024] Preferably, the bolt 8 between the connecting block 9 and the reinforcement ring 6 is a countersunk bolt, a countersunk hole 10 is opened on the connecting block 9, and a plurality of threaded holes 11 are opened on the reinforcement ring 6. The connecting block 9 and the threaded holes 11 are arranged in a one-to-one correspondence, the countersunk bolt is located in the countersunk hole 10, and the countersunk bolt is threadedly connected in the threaded hole 11. The design of the countersunk hole 10 ensures the smoothness of the outer surface of the annular side guard plate 7, protects the installed countersunk bolt, and prevents it from being scratched and deformed and affected by disassembly. The countersunk bolt can be directly screwed into the threaded hole 11 of the reinforcement ring 6 without the need to use a nut or a nut inside, which is easy to install and saves cost.

[0025] In this embodiment, a reinforcement ring 6 is welded and installed on the inner ring of the side of the rim 1. For a newly produced rim 1, it can be integrated during the production of the rim 1, and the annular side guard plate 7 is placed on the side of the tire 2, and all the connecting blocks 9 are inserted into the inner ring of the side of the rim 1. The countersunk holes 10 on the connecting blocks 9 and the threaded holes 11 on the reinforcement ring 6 are rotated to align, and the annular side guard plate 7 is installed on the reinforcement ring 6 by countersunk bolts to complete the installation; when the wheel assembly tire 2 is normally worn out and scrapped, the countersunk bolts are removed and the annular side guard plate 7 is removed for reuse.

[0026] It should be noted that, in this article, terms such as "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0027] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
