[0002] An excavator, also known as an excavating machine, is an earth-moving machine that uses a bucket to dig materials above or below the bearing surface and load them into transport vehicles or unload them to a stockpile. The materials excavated by the excavator are mainly soil, coal, silt, and pre-loosened soil and rocks. Judging from the development of construction machinery in recent years, the development of excavators has been relatively rapid. Excavators have become one of the most important construction machinery in engineering construction. Track wheels are an important component in the walking system of large construction machinery such as excavators. Track wheels need to be positioned when they are assembled, so a positioning device for track wheel assembly is needed.

[0003] When operators position the supporting rollers, they often use corresponding positioning devices for supporting roller assembly. Although the existing devices can achieve the purpose of positioning, the positioning method is single and the stability is poor during actual use. In addition, the supporting rollers need to be lifted manually during assembly. This operation method increases the labor intensity of the operators and may reduce the efficiency of assembly.
