Elevator landing door sill device with self-cleaning function

Abstract

The invention belongs to elevator components, and provides an elevator landing door sill device with a self-cleaning function. The elevator landing door sill device comprises a landing door sill and asill bracket; the landing door sill is provided with a sill groove, a hairbrush fixedly connected with a landing door is arranged in the sill groove, and a first ash leakage hole and a second ash leakage hole which are in communication with each other are correspondingly formed in the middle parts of the landing door sill and the sill bracket; the elevator landing door sill device further a dustcollecting device, a collecting box and a handle, wherein the dust collecting device comprises an ash discharging groove fixedly formed in the bottom of the sill bracket, the ash discharging groove isprovided with a feeding end and a discharging end, and the feeding end is located under the second ash leaking hole and is higher than the discharging end; the collecting box can move in the longitudinal direction and can move to the discharging end of the ash discharging groove so as to be used for collecting dust discharged from the ash discharging groove; the lower end of the handle is fixedlyconnected with the collecting box; and an ash taking opening allowing the collecting box and the handle to pass through is formed in the upper surface of the landing door sill, and a cover plate capable of being opened and closed is arranged at the ash taking opening. According to the elevator landing door sill device, the function that maintenance personnel regularly take away dust discharged from the dust leaking holes is achieved.

Description

technical field [0001] The invention belongs to elevator components, in particular to an elevator floor door sill device with self-cleaning function. Background technique [0002] In the sill groove connecting the landing door sill and the landing door, dust and debris tend to accumulate over a long period of time, resulting in the failure of the landing door to close normally. Usually, maintenance personnel are required to periodically clean the dust and foreign objects in the sill groove , time-consuming and laborious, and not easy to be removed. [0003] The utility model patent with the authorized notification number CN208150754U discloses a self-cleaning car sill device for elevators, which blows away the dust and debris in the sill groove by blowing air. The problem with this method is that the cleaning process There is a lot of dust, and the cleaning effect on small stones and other debris is poor. [0004] The utility model patent whose authorized notification numb...
