[0028] The mounting mechanism 2 includes a mounting component 21 and a cleaning component 22 , and the cleaning component 22 is arranged on the top of the mounting component 21 .

[0029] Furthermore, the mounting assembly 21 includes a return rope pulley shaft 211, which is arranged inside the mounting plate 31, a return rope pulley 212 is rotatably installed inside the return rope pulley shaft 211, a return rope pulley 212 is fixedly installed inside the return rope pulley shaft 211, a spring 213 is fixedly installed inside the return rope pulley shaft 211, a sliding block 214 is fixedly installed on the end of the spring 213 away from the return rope pulley shaft 211, a shift block 215 is fixedly installed on the front of the sliding block 214, and a plug-in frame 216 is fixedly installed on the front of the mounting plate 31, so that the return rope pulley shaft 211 will not fall off during the disassembly of the return rope pulley shaft 211, and the return rope pulley shaft 211 is protected during the disassembly process.

[0030] Furthermore, slots are provided at positions corresponding to the plug-in frame 216 and the sliding block 214, and the sliding block 214 is inserted into the slots. The sliding block 214 is slidably installed inside the return rope wheel shaft 211, and the hands of the staff support both ends of the return rope wheel shaft 211.

[0031] Furthermore, the cleaning component 22 includes a spring 221, which is fixedly installed inside the subbeam 1. A slider 222 is fixedly installed on one end of the spring 221 away from the spring 221. A cleaning roller 223 is rotatably installed inside the slider 222, so that the cleaning roller 223 can continuously contact the return rope wheel 212 to facilitate its cleaning.

[0032] Furthermore, a slide groove is provided at the corresponding position between the auxiliary beam 1 and the slider 222 , and the slider 222 is slidably installed inside the slide groove, so that the cleaning roller 223 rotates to clean the rope wound outside the return rope wheel 212 . Example

[0033] See also Figure 5 In combination with the first embodiment, it is further obtained that the rope blocking mechanism 3 includes a mounting plate 31, the mounting plate 31 is fixedly mounted on the inner side of the sub-beam 1, a threaded hole 32 is opened inside the mounting plate 31, a bolt 33 is threadedly mounted inside the threaded hole 32, a gasket 34 is arranged outside the bolt 33, a rope blocking plate 35 is arranged outside the bolt 33, and the rope blocking plate 35 protects the return rope wheel 212 to prevent the rope from falling off.

Since it is necessary to pinch the sliding block 214 inwardly, the staff's hands support both ends of the return rope wheel shaft 211 during the removal of the return rope wheel shaft 211, so that the return rope wheel shaft 211 will not fall during the disassembly of the return rope wheel shaft 211, and the return rope wheel shaft 211 is protected during the disassembly process. Then the through hole position of the rope retaining plate 35 corresponds to the threaded hole 32, and the bolt 33 is passed through the gasket 34 and the rope retaining plate 35 in turn to fix the rope retaining plate 35. The rope retaining plate 35 protects the return rope wheel 212 to prevent the rope from falling off. During the rotation of the return rope wheel 212, the cleaning roller 223 is driven to rotate. The cleaning roller 223 rotates to clean the rope wrapped around the outside of the return rope wheel 212 to prevent excessive accumulation of dust and impurities from affecting the operation of the return rope wheel 212. In addition, due to the setting of the spring 221, the cleaning roller 223 can continue to contact the return rope wheel 212, which is convenient for cleaning.
