Description

Technical Field

[0001] The utility model relates to the technical field of elevator guide shoes, in particular to a guide shoe assembly. Background Art

[0002] The guide shoe is a sliding nylon block between the elevator guide rail and the car. The guide shoe fixed on the car can move back and forth along the fixed guide rail installed on the wall of the building's hoistway to prevent the car from deflecting or swinging during operation.

[0003] A Chinese authorized patent with announcement number CN210594808U discloses an elevator guide shoe with a cleaning function, including a guide shoe frame, the guide shoe frame including a base, the base vertically connected to a first column and a second column, the first column is connected to a first roller, the second column is connected to a second roller, an end roller is connected between the first column and the second column, the guide shoe frame is also connected to a cleaning mechanism, the cleaning mechanism includes a first brush assembly connected to the first column, a second brush assembly connected to the second column, a third brush assembly connected to the bottom plate, a first brush assembly and a second brush assembly.

[0004] The above-mentioned elevator guide shoe with cleaning function cleans the three contact surfaces of the guide rail by means of a provided brush. However, in actual use, when too much impurities accumulate on the brush, the brush will shake when in contact with the guide rail when the elevator moves up and down, which may cause the impurities on the brush to fall onto the guide rail again, resulting in a poor cleaning effect on the guide rail. Moreover, if the particles attached to the guide rail are relatively stubborn, effective cleaning cannot be performed using only a brush.

[0005] To this end, we propose a guide shoe assembly. Utility Model Content
