[0020] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0021] like Figure 1-Figure 3As shown, the present embodiment provides a pulley block structure for a large-load freight elevator, comprising a bracket 5, a rotating shaft 4 is installed between the brackets 5, three groups of pulley sleeves 7 are installed in an array on the rotating shaft 4, and a wear-resistant pad 6 is arranged on the outer wall of the pulley sleeve 7, a bracket 5 is installed on one side of the support 1, three groups of fixed blocks 8 are installed in an array on the bracket 5, a telescopic column 10 is arranged on one side wall of the fixed block 8, a spring 11 is sleeved on the outer side of the telescopic column 10, a scraper 12 is fixed to the movable end of the telescopic column 10, a collecting trough 9 is installed on one side wall of the support 1, and a guide plate 2 is arranged on the inner bottom end of the support 1.

[0022] The rotating shaft 4 is rotatably connected to the bracket 5, the pulley sleeve 7 is fixed on the rotating shaft 4, the wear-resistant pad 6 is bonded to the pulley sleeve 7, the rotating shaft 4 and the pulley sleeve 7 are combined to guide the movement of the wire rope, and the wear-resistant pad 6 improves the wear resistance of the pulley sleeve 7.

[0023] The bracket 5 is welded to the support 1, and the fixing block 8 is connected to the bracket 5 by screws. The fixing block 8 provides an installation position for the cleaning mechanism.

[0024] The fixed part of the telescopic column 10 is fixedly connected to the fixed block 8, and the spring 11 is welded to the outer wall of the telescopic column 10. The combination of the telescopic column 10 and the spring 11 can make the scraper 12 have a mobile buffering performance, thereby protecting the wear-resistant pad 6 in the pulley sleeve 7 and itself.

[0025] The scraper blade 12 is connected to the movable end of the telescopic column 10 by screws. The scraper blade 12 is made of silicone. When the pulley sleeve 7 rotates, the scraper blade 12 can automatically scrape and clean the sludge formed therein.
