[0023] Reference Figures 1 to 4 A side mounting plate mounting fixing plate 9 is provided on the top of the elevator rope sheave side mounting plate 6, and two groups of symmetrical fixing plate mounting through holes 10 are opened on the top of the side mounting plate mounting fixing plate 9. A mounting fixing reinforcing rib 18 is provided at the contact position between the side mounting plate mounting fixing plate 9 and the elevator rope sheave side mounting plate 6. The elevator rope sheave side mounting plate 6 is fixedly connected to the side mounting plate mounting fixing plate 9, and the mounting fixing reinforcing rib 18 is fixedly connected to the side mounting plate mounting fixing plate 9. The elevator rope sheave can be fixed to other parts of the elevator through these fixing plate mounting through holes 10. The mounting fixing reinforcing rib 18 can improve the fixed connection effect of the side mounting plate mounting fixing plate 9 and the elevator rope sheave side mounting plate 6.

[0024] Reference Figures 1 to 4 A limiting shaft intermediate clamping plate 11 is provided on the outer center periphery of the intermediate limiting shaft 5 of the elevator rope sheave, and a limiting shaft intermediate clamping groove 12 is provided on the elevator rope sheave inner wheel 1 corresponding to the position of the limiting shaft intermediate clamping plate 11. The limiting shaft intermediate clamping plate 11 is fixedly connected to the intermediate limiting shaft 5 of the elevator rope sheave, which can make the connection between the intermediate limiting shaft 5 of the elevator rope sheave and the inner wheel 1 of the elevator rope sheave more stable, and also helps to position the intermediate limiting shaft 5 of the elevator rope sheave.

This design can ensure that when the elevator rope sheave is disassembled, there is enough space between the elevator rope sheave side mounting plates 6 for operation, further improving the convenience of disassembly of the elevator rope sheave.

[0029] The working principle of the utility model is as follows: first, the intermediate limiting shaft 5 of the elevator rope sheave is fixed to the center of the inner wheel 1 of the elevator rope sheave and is rotatably connected. The quick-release components on both sides of the intermediate limiting shaft 5 of the elevator rope sheave are composed of the elevator rope sheave side mounting plate 6, the side mounting plate mounting limiting hole 7 and the side mounting plate mounting limiting bolt 8. The fast fixing of the elevator rope sheave side mounting plate 6 is realized by the cooperation of the bolt and the side mounting plate mounting limiting hole 7. The side mounting plate mounting fixing plate 9 above the elevator rope sheave side mounting plate 6 and its fixing plate mounting through hole 10 are used to firmly mount the rope sheave on other components of the elevator. Then, the intermediate clamping plate 11 of the limiting shaft on the intermediate limiting shaft 5 of the elevator rope sheave cooperates with the intermediate clamping groove 12 of the limiting shaft of the inner wheel 1 of the elevator rope sheave, thereby enhancing the connection stability between the two. Moreover, the elevator rope sheave limiting plate 13 and the side mounting plate fastening bolt 15 further strengthen the connection between the elevator rope sheave side mounting plate 6 and the intermediate limiting shaft 5 of the elevator rope sheave. The setting of the limit shaft buffer washer 16 reduces the noise and wear caused by vibration and impact. At the same time, lubricating liquid can be injected into the connection through the sheave lubrication injection hole 17 on the elevator sheave inner wheel 1 to improve the operating efficiency of the elevator sheave. Finally, the sufficient spacing between the elevator sheave side mounting plates 6 ensures the convenience of operation during disassembly.
