[0024] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A wear-resistant chain for bucket elevators includes: an inner section 1, with two sets of wear-resistant rings 2 on the inner side of the inner section 1, a pin assembly movably mounted on the inner side of the wear-resistant rings 2, the pin assembly including a support block 4 mounted on the inner side of the wear-resistant rings 2, a limiting block 3 installed between the two sets of support blocks 4, an assembly shaft 5 mounted on one end of the limiting block 3, a first slot 6 on the outer side of the assembly shaft 5, a sealing ring 7 movably mounted on the outer side of the first slot 6, a limiting ring 8 mounted on the outer side of the assembly shaft 5, the limiting ring 8 abutting against the outer wall of the inner section 1, and the sealing ring 7 mounted on the inner side of a second slot 12;
[0025] The inner section 1 fixes the two sets of wear-resistant rings 2 on the inner side to ensure the stability of the two sets of wear-resistant rings 2. The two ends of the limiting block 3 are fixedly connected to the support block 4, and one end of the support block 4 is fixedly connected to the assembly shaft 5 to ensure the stability of the structure of the limiting block 3, the support block 4 and the assembly shaft 5. The first slot 6 is opened at one end of the assembly shaft 5. The first slot 6 limits the sealing ring 7 on the inner side. The support block 4 rotates inside the wear-resistant ring 2. The wear-resistant ring 2 improves the wear resistance of the chain and extends the service life of the chain.
[0026] The diameter of the limiting block 3 is larger than that of the support block 4. The limiting block 3 and the support block 4 work together to limit the wear-resistant ring 2, making it convenient for users to accurately install the inner section 1.
[0027] The surfaces of the limiting block 3, support block 4, and assembly shaft 5 are subjected to high-frequency treatment, and the core is subjected to tempering heat treatment. This improves fatigue strength and wear resistance.
[0028] A connecting assembly is movably mounted on the outer side of the assembly shaft 5. The connecting assembly includes a fixing sleeve 10 mounted on the outer side of the assembly shaft 5. The fixing sleeve 10 abuts against one side of the limiting ring 8. One end of the fixing sleeve 10 has a groove 11 and the other end has a second slot 12. An outer section 9 is mounted on the outer side of the fixing sleeve 10. An accessory piece 13 is mounted on one side of the outer section 9. A through opening is opened on the inner side of the accessory piece 13. The fixing sleeve 10 rotates on the outer side of the assembly shaft 5.
[0029] The assembly shaft 5 limits the outer fixing sleeve 10, making it convenient for users to accurately install the fixing sleeve 10 and disassemble the assembly chain. One end of the fixing sleeve 10 has a groove 11, which is locked on the outside of the limiting ring 8. The fixing sleeve 10 fixes the outer section 9, ensuring the stability of the outer section 9. The sealing ring 7 is installed inside the first slot 6 and the second slot 12 to block dust and debris, so as to protect the assembly shaft 5 from dust and debris adhesion during use and prevent jamming later.
[0030] Working principle: The inner section 1 fixes the two sets of wear-resistant rings 2 on the inner side, ensuring the stability of the two sets of wear-resistant rings 2. The two ends of the limiting block 3 are fixedly connected to the support block 4, and one end of the support block 4 is fixedly connected to the assembly shaft 5, ensuring the stability of the structure of the limiting block 3, support block 4, and assembly shaft 5. The first slot 6 is opened at one end of the assembly shaft 5, and the first slot 6 limits the sealing ring 7 on the inner side. The support block 4 rotates inside the wear-resistant ring 2. The wear-resistant ring 2 improves the wear resistance of the chain and extends the service life of the chain. The diameter of the limiting block 3 is larger than the diameter of the support block 4. The support block 4 cooperates with the wear-resistant ring 2 to limit the position, making it convenient for the user to accurately install the inner section 1. The assembly shaft 5 limits the outer fixing sleeve 10 to limit the position, making it convenient for the user to accurately install the fixing sleeve 10. One end of the fixing sleeve 10 has a groove 11, which is locked on the outside of the limiting ring 8. The fixing sleeve 10 fixes the outer section 9 to ensure the stability of the outer section 9. The sealing ring 7 is installed inside the first slot 6 and the second slot 12 to block dust and debris, so as to protect the assembly shaft 5 from dust and debris adhering to the assembly shaft 5 during use and prevent jamming later.
