[0021] Please see Figures 1-4 A traction wheel for a traction machine;

[0022] It includes: a support shaft 1, a telescopic assembly installed at one end of the support shaft 1, the telescopic assembly including a mounting groove 4, a positioning groove 5, a spring body 6, a movable shaft 7 and a positioning block 8, the mounting groove 4 is opened at one end of the support shaft 1, the positioning groove 5 is symmetrically opened on the inner walls of both sides of the mounting groove 4, the movable shaft 7 is movably installed inside the mounting groove 4, the positioning block 8 connected to the positioning groove 5 is symmetrically installed on the outer side of the movable shaft 7, and the spring body 6 is installed between the movable shaft 7 and the mounting groove 4, and the two ends of the spring body 6 are respectively connected to the mounting groove 4 and the movable shaft 7;

[0023] The support shaft 1 serves as the internal support for the traction wheel and also provides an installation position for the telescopic assembly. The telescopic assembly is installed at one end of the support shaft 1, and its telescopic effect facilitates the disassembly of the traction wheel. When the traction wheel is disassembled via the support shaft 1, since the two ends of the traction wheel are rotatably connected by the first rotating shaft 3 and the second rotating shaft 9, and the second rotating shaft 9 is connected to the telescopic assembly, the movable shaft 7 in the telescopic assembly is movably installed inside the mounting groove 4 via the spring body 6. By moving the support shaft 1 towards one end of the telescopic assembly, the telescopic assembly is compressed, thereby causing the first rotating shaft 3 at the other end of the support shaft 1 to leave the installation position, making the disassembly of the traction wheel more convenient. When the telescopic assembly extends or retracts, the support shaft 1 moves outside the movable shaft 7 through the mounting groove 4. In order to ensure stable rotation of the traction wheel, the positioning block 8 in the telescopic assembly is located inside the positioning groove 5, ensuring stable operation of the telescopic assembly.

[0024] A second rotating shaft 9 is installed at the other end of the movable shaft 7;

[0025] The second rotating shaft 9 is used for movable installation at the desired location, thereby enabling the traction wheel to be rotated and installed at the desired location.

[0026] A mounting shaft 2 is installed at the other end of the support shaft 1, and a first rotating shaft 3 is installed at one end of the mounting shaft 2;

[0027] The other end of the support shaft 1 is mounted on the first rotating shaft 3 via the mounting shaft 2, so that the support shaft 1 is rotated and supported in the required position.

[0028] Multiple limiting grooves 10 are provided on the outer side of the support shaft 1. A wear-resistant sleeve 11 is installed on the outer side of the support shaft 1 through the limiting grooves 10. Multiple limiting blocks 12 are installed on the inner wall of the wear-resistant sleeve 11, and the limiting blocks 12 are fitted and connected to the limiting grooves 10.

[0029] The limiting groove 10 provides a limiting space for the installation of the wear-resistant sleeve 11. When the wear-resistant sleeve 11 is installed, the inner side of the wear-resistant sleeve 11 is fixedly fitted into the inside of the limiting groove 10 by the limiting block 12, so that the wear-resistant sleeve 11 is stably installed on the outside of the support shaft 1, making the stability of the wear-resistant sleeve 11 higher. The wear-resistant sleeve 11 is installed on the outside of the support shaft 1, making the wear resistance of the traction wheel higher.

[0030] The working principle is as follows: First, when the traction wheel is installed and used, it is installed in the required position using the first rotating shaft 3 and the second rotating shaft 9, so that the traction wheel can rotate and be used. When the traction wheel is disassembled, since one end of the second rotating shaft 9 is connected to the telescopic component, the operator retracts the telescopic component to make the first rotating shaft 3 at the other end of the traction wheel leave the installation position, thus making the traction wheel more convenient to disassemble and improving the disassembly efficiency. At the same time, the inner side of the wear-resistant sleeve 11 is fixedly fitted into the inside of the limiting groove 10 by the limiting block 12, so that the wear-resistant sleeve 11 is stably installed on the outside of the support shaft 1, making the wear-resistant sleeve 11 more stable. The wear-resistant sleeve 11 installed on the outside of the support shaft 1 makes the traction wheel more wear-resistant.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
